NAFLD vs. MAFLD: What’s in a name?
Non-alcoholic fatty liver disease (NAFLD) and metabolic associated fatty liver disease (MAFLD) demonstrate highly similar clinical courses and mortality rates, and a name change may not be clinically beneficial, based on data from more than 17,000 patients.
Instead, etiologic subcategorization of fatty liver disease (FLD) should be considered, reported lead author Zobair M. Younossi, MD, of Betty and Guy Beatty Center for Integrated Research, Inova Health System, Falls Church, Va., and colleagues.
“There is debate about whether NAFLD is an appropriate name as the term ‘non-alcoholic’ overemphasizes the absence of alcohol use and underemphasizes the importance of the metabolic risk factors which are the main drivers of disease progression,” the investigators wrote in Hepatology. “It has been suggested that MAFLD may better reflect these risk factors. However, such a recommendation is made despite a lack of a general consensus on the definition of ‘metabolic health’ and disagreements in endocrinology circles about the term ‘metabolic syndrome.’ Nevertheless, a few investigators have suggested that MAFLD but not NAFLD is associated with increased fibrosis and mortality.”
To look for clinical differences between the two disease entities, Dr. Younossi and colleagues turned to the National Health and Nutrition Examination Survey (NHANES). Specifically, the NHANES III and NHANES 2017-2018 cohorts were employed, including 12,878 and 4,328 participants, respectively.
MAFLD was defined as FLD with overweight/obesity, evidence of metabolic dysregulation, or type 2 diabetes mellitus. NAFLD was defined as FLD without excessive alcohol consumption or other causes of chronic liver disease. Patients were sorted into four groups: NAFLD, MAFLD, both disease types, or neither disease type. Since the categories were not mutually exclusive, the investigators compared clinical characteristics based on 95% confidence intervals. If no overlap was found, then differences were deemed statistically significant.
Diagnoses of NAFLD and MAFLD were highly concordant (kappa coefficient = 0.83-0.94). After a median of 22.8 years follow-up, no significant differences were found between groups for cause-specific mortality, all-cause mortality, or major clinical characteristics except those inherent to the disease definitions (for example, lack of alcohol use in NAFLD). Greatest risk factors for advanced fibrosis in both groups were obesity, high-risk fibrosis, and type 2 diabetes mellitus.
As anticipated, by definition, alcoholic liver disease and excess alcohol use were documented in approximately 15% of patients with MAFLD, but in no patients with NAFLD. As such, alcoholic liver disease predicted liver-specific mortality for MAFLD (hazard ratio, 4.50; 95% confidence interval, 1.89-10.75) but not NAFLD. Conversely, insulin resistance predicted liver-specific mortality in NAFLD (HR, 3.57; 95% CI, 1.35-9.42) but not MAFLD (HR, 0.84; 95% CI, 0.36-1.95).
“These data do not support the notion that a name change from NAFLD to MAFLD will better capture the risk for long-term outcomes of these patients or better define metabolically at-risk patients who present with FLD,” the investigators concluded. “On the other hand, enlarging the definition to FLD with subcategories of ‘alcoholic,’ ‘non-alcoholic,’ ‘drug-induced,’ etc. has merit and needs to be further considered. In this context, a true international consensus group of experts supported by liver and non-liver scientific societies must undertake an evidence-based and comprehensive approach to this issue and assess both the benefits and risks of changing the name.”
According to Rohit Loomba, MD, director of the NAFLD research center and professor of medicine in the division of gastroenterology and hepatology at University of California, San Diego, the study offers a preview of the consequences if NAFLD were changed to MAFLD, most notably by making alcohol a key driver of outcomes.
“If we change the name of a disease entity ... how does that impact natural history?” Dr. Loomba asked in an interview. “This paper gives you an idea. If you start calling it MAFLD, then people are dying from alcohol use, and they’re not dying from what we are currently seeing patients with NAFLD die of.”
He also noted that the name change could disrupt drug development and outcome measures since most drugs currently in development are directed at nonalcoholic steatohepatitis (NASH).
“Is it worth the headache?” Dr. Loomba asked. “How are we going to define NASH-related fibrosis? That probably will remain the same because the therapies that we will use to address that will remain consistent with what we are currently pursuing. ... It’s probably premature to change the nomenclature before assessing the impact on finding new treatment.”

Screening for diabetes at normal BMIs could cut racial disparities
Use of race-based diabetes screening thresholds could reduce the disparity that arises from current screening guidelines in the United States, new research suggests.
In August 2021, the U.S. Preventive Services Task Force (USPSTF) lowered the recommended age for type 2 diabetes screening from 40 to 35 years among people with a body mass index of 25 kg/m2 or greater.
However, the diabetes rate among ethnic minorities aged 35-70 years in the United States is not just higher overall but, in certain populations, also occurs more frequently at a younger age and at lower BMIs, the new study indicates.
Among people with a BMI below 25 kg/m2, the diabetes prevalence is two to four times higher among Asian, Black, and Hispanic Americans than among the U.S. White population.
And the authors of the new study, led by Rahul Aggarwal, MD, predict that if screening begins at age 35 years, the BMI cut-off equivalent to 25 kg/m2 for White Americans would be 18.5 kg/m2 for Hispanic and Black Americans and 20 kg/m2 for Asian Americans.
“While diabetes has often been thought of as a disease that primarily affects adults with overweight or [obesity], our findings suggest that normal-weight adults in minority groups have surprisingly high rates of diabetes,” Dr. Aggarwal, senior resident physician in internal medicine at Harvard Medical School, Boston, told this news organization.
“Assessing diabetes risks in certain racial/ethnic groups will be necessary, even if these adults do not have overweight or [obesity],” he added.
Not screening in this way “is a missed opportunity for early intervention,” he noted.
And both the authors and an editorialist stress that the issue isn’t just theoretical.
“USPSTF recommendations influence what payers choose to cover, which in turn determines access to preventative services ... Addressing the staggering inequities in diabetes outcomes will require substantial investments in diabetes prevention and treatment, but making screening more equitable is a good place to start,” said senior author Dhruv S. Kazi, MD, of the Smith Center for Outcomes Research in Cardiology and director of the Cardiac Critical Care Unit at Beth Israel, Boston.
Screen minorities at a younger age if current BMI threshold kept
In their study, based on data from the National Health and Nutrition Examination Survey (NHANES) for 2011-2018, Dr. Aggarwal and colleagues also calculated that, if the BMI threshold is kept at 25 kg/m2, then the equivalent age cut-offs for Asian, Black, and Hispanic Americans would be 23, 21, and 25 years, respectively, compared with 35 years for White Americans.
The findings were published online in the Annals of Internal Medicine.
The prevalence of diabetes in those aged 35-70 years in the NHANES population was 17.3% for Asian Americans and 12.5% for those who were White (odds ratio, 1.51 vs. Whites). Among Black Americans and Mexican Americans, the prevalence was 20.7% and 20.6%, respectively, almost twice the prevalence in Whites (OR, 1.85 and 1.80). For other Hispanic Americans, the prevalence was 16.4% (OR, 1.37 vs. Whites). All of those differences were significant, compared with White Americans.
Undiagnosed diabetes was also significantly more common among minority populations, at 27.6%, 22.8%, 21.2%, and 23.5% for Asian, Black, Mexican, and other Hispanic Americans, respectively, versus 12.5% for White Americans.
‘The time has come for USPSTF to offer more concrete guidance’
“While there is more work to be done on carefully examining the long-term risk–benefit trade-off of various diabetes screening, I believe the time has come for USPSTF to offer more concrete guidance on the use of lower thresholds for screening higher-risk individuals,” Dr. Kazi told this news organization.
The author of an accompanying editorial agrees, noting that in a recent commentary the USPSTF, itself, “acknowledged the persistent inequalities across the screening-to-treatment continuum that result in racial/ethnic health disparities in the United States.”
And the USPSTF “emphasized the need to improve systems of care to ensure equitable and consistent delivery of high-quality preventive and treatment services, with special attention to racial/ethnic groups who may experience worse health outcomes,” continues Quyen Ngo-Metzger, MD, Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, California.
For other conditions, including cancer, cardiovascular disease, and infectious disease, the USPSTF already recommends risk-based preventive services.
“To address the current inequity in diabetes screening, the USPSTF should apply the same consideration to its diabetes screening recommendation,” she notes.
‘Implementation will require an eye for pragmatism’
Asked about how this recommendation might be carried out in the real world, Dr. Aggarwal said in an interview that, because all three minority groups with normal weight had similar diabetes risk profiles to White adults with overweight, “one way for clinicians to easily implement these findings is by screening all Asian, Black, and Hispanic adults ages 35-70 years with normal weight for diabetes, similarly to how all White adults ages 35-70 years with overweight are currently recommended for screening.”
Dr. Kazi said: “I believe that implementation will require an eye for pragmatism,” noting that another option would be to have screening algorithms embedded in the electronic health record to flag individuals who qualify.
In any case, “the simplicity of the current one-size-fits-all approach is alluring, but it is profoundly inequitable. The more I look at the empiric evidence on diabetes burden in our communities, the more the status quo becomes untenable.”
However, Dr. Kazi also noted, “the benefit of any screening program relates to what we do with the information. The key is to ensure that folks identified as having diabetes – or better still prediabetes – receive timely lifestyle and pharmacological interventions to avert its long-term complications.”
This study was supported by institutional funds from the Richard A. and Susan F. Smith Center for Outcomes Research in Cardiology. Dr. Aggarwal, Dr. Kazi, and Dr. Ngo-Metzger have reported no relevant relationships.

Obesity interactions complex in acute pancreatitis
Obesity, in combination with other risk factors, is associated with increased morbidity and mortality in acute pancreatitis (AP); however, body mass index (BMI) alone is not a successful predictor of disease severity, new research shows.
“As there was no agreement or consistency between BMI and AP severity, it can be concluded that AP severity cannot be predicted successfully by examining BMI only,” reported the authors in research published recently in Pancreatology.
The course of acute pancreatitis is typically mild in the majority (80%-85%) of cases; however, in severe cases, permanent organ failure can occur, with much worse outcomes and mortality rates of up to 35%.
Research has previously shown not only a link between obesity and acute pancreatitis but also an increased risk for complications and in-hospital mortality in obese patients with severe cases of acute pancreatitis – though a wide range of factors and comorbidities may complicate the association.
To more closely evaluate the course and outcomes of acute pancreatitis based on BMI classification, study authors led by Ali Tuzun Ince, MD, of the department of internal medicine, Gastroenterology Clinic of Bezmialem Vakif University, Istanbul, analyzed retrospective data from 2010 to 2020 on 1,334 adult patients (720 female, 614 male) who were diagnosed with acute pancreatitis per the Revised Atlanta Classification (RAC) criteria.
The patients were stratified based on their BMI as normal weight, overweight, or obese and whether they had mild, moderate, or severe (with permanent organ failure) acute pancreatitis.
In terms of acute pancreatitis severity, based on RAC criteria, 57.1% of patients had mild disease, 20.4% had moderate disease, and 22.5% had severe disease.
The overall mortality rate was 9.9% (n = 132); half of these patients were obese, and 87% had severe acute pancreatitis.
The overall rate of complications was 42.9%, including 20.8% in the normal weight group, 40.6% in the overweight group, and 38.6% in the obese group.
Patients in the overweight and obese groups also had higher mortality rates (3.7% and 4.9%, respectively), interventional procedures (36% and 39%, respectively), and length of hospital stay (11.6% and 9.8%, respectively), compared with the normal-weight group.
Other factors that were significantly associated with an increased mortality risk, in addition to obesity (P = .046), included old age (P = .000), male sex (P = .05), alcohol use (P = .014), low hematocrit (P = .044), high C-reactive protein (P = .024), moderate to severe and severe acute pancreatitis (P = .02 and P < .001, respectively), and any complications (P < .001).
Risk factors associated with increased admission to the ICU differed from those for mortality, and included female gender (P = .024), smoking (P = .021), hypertriglyceridemia (P = .047), idiopathic etiology (P = .023), and moderate to severe and severe acute pancreatitis (P < .001).
Of note, there were no significant associations between BMI and either the RAC score or Balthazar CT severity index (Balthazar CTSI) groups.
Specifically, among patients considered to have severe acute pancreatitis per Balthazar CTSI, 6.3% were of normal weight, 5% were overweight, and 7.1% were obese.
“In addition, since agreement and consistency between BMI and Balthazar score cannot be determined, the Balthazar score cannot be estimated from BMI,” the authors reported.
While the prediction of prognosis in acute pancreatitis is gaining interest, the findings underscore the role of combined factors, they added.
“Although many scoring systems are currently in use attempt to estimate the severity [in acute pancreatitis], none is 100% accurate yet,” the authors noted. “Each risk factor exacerbates the course of disease. Therefore, it would be better to consider the combined effects of risk factors.”
That being said, the findings show “mortality is increased significantly by the combined presence of risk factors such as male sex, OB [obesity], alcohol, MSAP [moderate to severe acute pancreatitis] and SAP [severe acute pancreatitis], all kinds of complications, old age, low Hct, and high CRP,” they wrote.
Obesity’s complex interactions
Commenting on the study, Vijay P. Singh, MD, a professor of medicine in the division of gastroenterology and hepatology at the Mayo Clinic in Scottsdale, Ariz., agreed that the complexities risk factors, particularly with obesity, can be tricky to detangle.
“Broadly, the study confirms several previous reports from different parts of the world that obesity was associated with increased mortality in acute pancreatitis,” he said in an interview.
“However, obesity had two complex interactions, the first that obesity is also associated with increased diabetes, and hypertriglyceridemia, which may themselves be risk factors for severity,” he explained.
“The second one is that intermediary severity markers [e.g., Balthazar score on imaging] did not correlate with the BMI categories.”
Dr. Singh noted that is “likely because therapies like IV fluids that may get more intense in predicted severe disease alter the natural course of pancreatitis.”
The findings are a reminder that “BMI is only a number that attempts to quantify fat,” Dr. Singh said, noting that BMI doesn’t address either the location of fat, such as being in close proximity to the pancreas, or fat composition, such as the proportion of unsaturated fat.
“When the unsaturated fat proportion is higher, the pancreatitis is worse, even at smaller total fat amounts [for example, at a lower BMI],” he said. “Taking these aspects into account may help in risk assessment.”
The authors and Dr. Singh had no disclosures to report.
Obesity, in combination with other risk factors, is associated with increased morbidity and mortality in acute pancreatitis (AP); however, body mass index (BMI) alone is not a successful predictor of disease severity, new research shows.

Vegan diet helps shed pounds but doesn’t dint diabetes
on average, new research indicates.
No effect was seen on blood pressure, triglycerides, or high-density lipoprotein cholesterol. HbA1c was reduced by a mean of –0.18 percentage points (P = .002), and there was a small reduction in total cholesterol and low-density lipoprotein cholesterol, on average, across all the studies examined in this meta-analysis.
The work, which compared a number of trials looking at vegan diets versus “normal” eating or other kinds of weight loss diets, “indicates with reasonable certainty that adhering to a vegan diet for at least 12 weeks may result in clinically meaningful weight loss [and] can be used in the management of overweight and type 2 diabetes,” said Anne-Ditte Termannsen, PhD, who reported the findings during a press conference at the European Congress on Obesity 2022, where the work was also presented as a poster.
A vegan diet most likely led to weight loss because it is “associated with a reduced calorie intake due to a lower content of fat and higher content of dietary fiber,” added Dr. Termannsen of the Steno Diabetes Center Copenhagen.
Asked to comment, Janet Cade, PhD, who leads the Nutritional Epidemiology Group at the University of Leeds (England) said the results are likely attributable to fewer calories in the vegan diet, compared with the “control” diets. “Of course, a vegan diet can be healthier in a range of ways, such as higher fruit and vegetables, more fiber and antioxidants; however, the same would be true of a vegetarian diet,” she noted.
And she warned that longer-term data are needed on health outcomes associated with vegan diets, noting, “there have been links to poorer bone health and osteoporosis in people consuming a vegan diet.”
Gunter Kuhnle, PhD, professor of nutrition and food science, University of Reading (England) told the UK Science Media Centre: “The authors conducted a systematic review of intervention studies and found that, compared with no dietary interventions, vegan diets showed the strongest association with body-weight reduction.”
However, “When comparing vegan diets with other dietary interventions – such as the Mediterranean diet – the association was much weaker,” he noted.
Vegan, habitual, or a range of weight-loss diets
Dr. Termannsen and colleagues set out to look at the effect of a plant-based diet on cardiometabolic risk factors in people with overweight or type 2 diabetes. They searched the literature for randomized controlled trials with adult participants with overweight (body mass index ≥ 25 kg/m2), prediabetes, or type 2 diabetes.
Participants followed a vegan diet that lasted at least 12 weeks; habitual diets without any changes or energy restriction; a Mediterranean diet; a host of different “diabetes” diets; a low-fat diet; or portion-controlled diets.
“The vegan diets were nearly all low-fat vegan diets but vary substantially regarding the protein, fat, carbohydrate content. All but one study was ad libitum fat, and there were no energy restrictions,” Dr. Termannsen said.
Control diets were more varied. “Some continued their habitual diet, and about half were energy restricted and the others were not,” she acknowledged.
Outcomes comprised body weight, BMI, HbA1c, systolic and diastolic blood pressure, total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides, which were assessed across studies.
A total of 11 trials were included in the meta-analysis, and studies were a mean duration of 19 weeks. A total of 796 participants were included.
Compared with control diets, those on vegan diets lost on average –4.1 kg (–9 lb) (P < .001), with a range of –5.9 kg to –2.4 kg.
BMI dropped by –1.38 kg/m2 (P < .001). Total cholesterol dropped by –0.30 mmol/L (–11.6 mg/dL; P = .007) and LDL cholesterol by –0.24 mmol/L (–9.28 mg/dL; P = .005).
Further analyses found even greater reductions in body weight and BMI when vegan diets were compared with continuing a normal diet without dietary changes, on average, at –7.4 kg (–16.3 lb) (P < .001) and –2.78 kg/m2 (P < .001) respectively.
When compared with other intervention diets, however, body weight dropped by –2.7 kg (–6 lb; P < .001) and BMI by –0.87 kg/m2 (P < .001).
Commenting on limitations of studies compared to the real world, Dr. Termannsen said: “Some studies reported high adherence to their diet, usually due to a high level of support, suggesting that providing continued face-to-face contact with participants may partly explain the adherence differences.”
“This also questions the long-term feasibility of the diet and the applicability of this as long-term care,” she added.
Following a vegan diet requires good planning to ensure adequate nutrition and avoid any deficiencies, she urged. “We need to remember that the menu plans in the studies were created by dietitians.”

FROM ECO 2022
One in four obese teens don’t know they’re obese
New research from 10 countries around the globe, including 1,164 participants from the United Kingdom, presented at this year’s European Congress on Obesity shows that nearly one-quarter (24%) of adolescents living with obesity (ALwO) do not know they have obesity.
“The impact of obesity – in children and adults – on individuals, society, and our health care systems should not be underestimated,” said lead author Professor Jason C.G. Halford, PhD, C.Psychol, AFBPS, head of the school of psychology, University of Leeds (England), and president of the European Association for the Study of Obesity.
The new findings come from the ACTION teens global survey study, a quantitative survey-based study that collected data in 10 countries (Australia, Colombia, Italy, Korea, Mexico, Saudi Arabia, Spain, Taiwan, Turkey, and the United Kingdom) and included ALwO, their caregivers, and health care professionals (HCPs) who had direct, recent experience of clinical obesity management in adolescents.
Included in the survey were:
- 5,275 ALwO aged 12-17 years with current body mass index–for-age (based on self-reported sex, age, height, and weight) in the top 5% (≥95th percentile) for age and sex.
- 5,389 caregivers aged 25 years and over, who were the parent or legal guardian of an ALwO who lived in the same household at least 50% of the time and were involved in their ALwO’s health care decisions.
- 2,323 HCP, primary care physicians, pediatricians, or other specialists, who had been in clinical practice for at least 2 years, spent at least 50% of their time in direct patient care, and treated at least 10 ALwO in a typical month
An online panel, telephone calls, and in-person meetings were utilized to survey participants on a wide range of topics, including attitudes towards obesity and its impact, number of weight-loss attempts, and motivations/barriers to weight loss.
Many believe losing weight is their sole responsibility
The authors reported that around 9 out of 10 (89%) HCPs indicated that obesity has a strong impact on a person’s overall health and wellbeing. Fewer ALwO and caregivers, however, had similar views about this (72% and 67% respectively). In addition, the authors said that “most participants thought obesity was at least as, or more, impactful than heart disease, cancer, or diabetes.”
Despite many ALwO not recognizing being obese, most surveyed (85%) were worried about the impact of their weight on their future health, with two-thirds (65%) feeling it was their sole responsibility to deal with their excess weight. This compared to 37% of caregivers and around one in four HCPs (27%) feeling that losing weight was solely the ALwO’s responsibility.
Study coauthor Vicki Mooney, chairwoman of the Irish Coalition for People Living with Obesity and executive director of the European Coalition for People living with Obesity, said: “It is hard to fathom the pressure for these teenagers, especially as two-thirds believe it is their sole responsibility to lose weight, with many of their parents/caregivers struggling to know how to best care for their child.”
Teenagers unable to speak to parents about losing weight
Many ALwO said they struggled to talk to those closest to them about their weight, with 1 in 3 saying they couldn’t talk to either parent about their weight, and alarmingly 1 in 10 feeling they couldn’t talk to anyone about their weight. However, around one in three could talk to their doctor, and 74% said that they trusted the advice of a HCP about weight management.
Ms. Mooney said: “The results show us teenagers want to lose weight and improve their health, however, one in three teenagers feel unable to speak to their parents about it and many revert to social media for guidance.”
When it came to sources of information YouTube (34%), social media (28%), family and friends (25%), search engines (25%), and doctors (24%) were the most popular.
Motivation, barriers, and attempts
Weight-loss attempts by ALwO appeared to be underestimated by HCPs, the authors explained, while caregivers tended to underestimate both the impact of obesity on health and wellbeing, and ALwO’s weight-loss attempts.
Efforts had been made to try and lose weight in the past year by more than half (58%) of ALwO, with three-quarters (75%) being somewhat/very likely to attempt to lose weight in the next 6 months. However, fewer (41%) caregivers reported that their ‘linked’ ALwO attempted weight loss over the past year or that their ALwO was somewhat/very likely (63%) to attempt to lose weight in the next 6 months. Amongst HCPs, only about two out of five (38%) responded that their ALwO patients had made a serious weight loss attempt in the past year.
Motivation is a key component of successful weight reduction and wanting to be more fit/in better shape (40%), not being happy with their weight (37%), and wanting to feel more confident (35%) were the most common motivators for ALwO, and also the most common motivators reported by caregivers for their ALwO. For HCPs, though, things were somewhat different, with the top three motivators they reported for ALwO to lose weight were wanting the have more confidence/self-esteem (69%), improved social life and popularity (69%), and wanting to look like peers their age (65%).
The top three barriers to losing weight reported by ALwO and by caregivers for their ALwO were not being able to control hunger (38%), lack of motivation (34%), and enjoying eating unhealthy food (32%). For HCPs, the top three barriers they reported for ALwO losing weight were unhealthy eating habits (93%), lack of exercise (92%), and enjoying eating unhealthy food (91%).
“Key motivations and barriers for weight loss were not aligned between ALwO and HCPs,” said the authors. They pointed out that these disconnects may “negatively impact the level of support and effectiveness” of obesity care ALwO receive from caregivers and HCPs.
Prof. Halford said: “There is urgent need for governments and society to recognize and treat obesity as a disease, so that more teens can get the right support to help them live happier and healthier lives.”

New research from 10 countries around the globe, including 1,164 participants from the United Kingdom, presented at this year’s European Congress on Obesity shows that nearly one-quarter (24%) of adolescents living with obesity (ALwO) do not know they have obesity.
“The impact of obesity – in children and adults – on individuals, society, and our health care systems should not be underestimated,” said lead author Professor Jason C.G. Halford, PhD, C.Psychol, AFBPS, head of the school of psychology, University of Leeds (England), and president of the European Association for the Study of Obesity.
The new findings come from the ACTION teens global survey study, a quantitative survey-based study that collected data in 10 countries (Australia, Colombia, Italy, Korea, Mexico, Saudi Arabia, Spain, Taiwan, Turkey, and the United Kingdom) and included ALwO, their caregivers, and health care professionals (HCPs) who had direct, recent experience of clinical obesity management in adolescents.
Included in the survey were:
- 5,275 ALwO aged 12-17 years with current body mass index–for-age (based on self-reported sex, age, height, and weight) in the top 5% (≥95th percentile) for age and sex.
- 5,389 caregivers aged 25 years and over, who were the parent or legal guardian of an ALwO who lived in the same household at least 50% of the time and were involved in their ALwO’s health care decisions.
- 2,323 HCP, primary care physicians, pediatricians, or other specialists, who had been in clinical practice for at least 2 years, spent at least 50% of their time in direct patient care, and treated at least 10 ALwO in a typical month
An online panel, telephone calls, and in-person meetings were utilized to survey participants on a wide range of topics, including attitudes towards obesity and its impact, number of weight-loss attempts, and motivations/barriers to weight loss.
Many believe losing weight is their sole responsibility
The authors reported that around 9 out of 10 (89%) HCPs indicated that obesity has a strong impact on a person’s overall health and wellbeing. Fewer ALwO and caregivers, however, had similar views about this (72% and 67% respectively). In addition, the authors said that “most participants thought obesity was at least as, or more, impactful than heart disease, cancer, or diabetes.”
Despite many ALwO not recognizing being obese, most surveyed (85%) were worried about the impact of their weight on their future health, with two-thirds (65%) feeling it was their sole responsibility to deal with their excess weight. This compared to 37% of caregivers and around one in four HCPs (27%) feeling that losing weight was solely the ALwO’s responsibility.

‘Critical window’ to intervene for weight issues in early childhood
Signs of cardiometabolic damage in children who are overweight appear as early as 6-8 years of age, but were not evident in preschoolers, providing a window of opportunity for intervention, show the latest results from a long-running Danish study of childhood weight.
The proportion of children who were overweight (nearly 14% in 2015) was similar between the two groups – those of preschool age (2-5 years) and school age (6-8 years) – but only the latter showed significant signs of cardiometabolic abnormalities.
The results, published in Obesity Research & Clinical Practice, are the latest in a series of many findings from the HOLBAEK study (formerly known as The Danish Childhood Obesity Biobank) that have emerged since it began in 2007. They were presented, along with a meta-analysis of much of their work, at the European Congress on Obesity (ECO) 2022.
“When comparing children with and without overweight, there were only barely significant differences among the preschool children,” said investigator Christine Frithioff-Bøjsøe, MD, but in contrast, “the school children with overweight exhibited significantly higher systolic blood pressure, glucose, insulin, and higher HDL cholesterol,” among other markers, she noted.
“Detection needs to start as early as age 2-5 years because if you wait just a few years longer these children will show early signs of disease starting to take hold. This could provide a critical window to detect and manage overweight,” said Frithioff-Bøjsøe, PhD, of the Children’s Obesity Clinic, Copenhagen University, Hospital Holbaek, Denmark.
Asked to comment, Aaron S. Kelly, PhD, professor of pediatrics, codirector, University of Minnesota Center for Pediatric Obesity Medicine in Minneapolis, said: “Recent results from HOLBAEK highlight the critical importance of identifying obesity early in life, before its complications spring up.
“Ideally, we should be in the business of managing and reducing excess adiposity as soon as it surfaces with the goal of preventing the onset of cardiometabolic risk factors, not watchful waiting and hoping for the best.”
Routine dental visits checked overweight
In the newest study, the researchers trained dental assistants to measure weight and height and carried out body mass index assessments during routine appointments.
A total of 335 preschool and 657 school-age children were recruited for the study. Of these, 40% attended additional hospital-based examinations including blood pressure measurement and a blood sample. Children were reexamined approximately 1 year later.
Systolic blood pressure, for example, was significantly higher in 6- to 8-year-olds with overweight compared to those of normal weight (P = .001). There was no significant difference between systolic blood pressure of 2.5- to 5-year-olds without and with overweight.
Likewise, with insulin resistance, there was no significant difference between preschoolers with and without overweight. However, in schoolchildren, homoeostasis model of assessment–insulin resistance (HOMA-IR) was significantly higher in those with overweight, at 2.2, compared to those without, at 0.9 (P < .001).
Also, during follow-up (around a year later), the prevalence of overweight did not change in preschool children but increased from 13.7% to 17.0% in schoolchildren.
The researchers noted that, in Europe, it is the primary health care sector that has continuous contact with the pediatric population, with the potential for early evaluation of children at risk. Their decision to use dental health care assistants to assess weight in this particular study is novel, but feasible, they observed.
Danish model for treating overweight and obesity is ‘game-changing’
As part of the HOLBAEK initiative, clinical data and biological samples have been collected from children and adolescents receiving treatment at The Children’s Obesity Clinic, Holbaek Hospital, using a population-based cohort as a reference group. Data have been collected on about 8,000 children and adolescents so far.
Jens-Christian Holm, PhD, along with colleague and research assistant Maria Frauland, both from Copenhagen University, Hospital Holbaek, presented a review of the HOLBAEK studies (2007-2021) at ECO 2022. They said the results highlight the importance of taking an integrated approach to managing children and adolescents with obesity.
The review, which included 82 papers, found a wide variety of obesity-related complications already present at a young age in some of the cross-sectional studies, including dyslipidemia in 28% of children with obesity, hepatic steatosis in 31%, obstructive sleep apnea in 45%, and prehypertension or hypertension in 52%.
The family-based interventional weight management programs adopted by HOLBAEK showed a 75% reduction in the “degree of obesity,” which comprised a measure of dyslipidemia, hypertension, hepatic steatosis, sleep apnea, and parental obesity.
“The HOLBAEK method is a holistic approach where we integrate everything,” Dr. Holm told this news organization.
Ms. Frauland said: “The HOLBAEK study has provided important insights into childhood overweight. It has highlighted that obesity is a serious multisystem disease that can be managed and treated effectively, reducing the degree of overweight and improving overweight-related complications.”
Dr. Kelly, the U.S. pediatrician, applauded the HOLBAEK philosophy, which emphasizes that obesity is not the fault of the child or parent, but rather the manifestation of dysregulated energy metabolism. “The recognition that obesity is a biologically driven, chronic, refractory, and relapsing disease is interwoven into the approach, which shifts the responsibility to the care provider for ensuring positive outcomes of treatment.
“Highlighting this fact to the parents and child can be game-changing since it removes the blame and shame associated with obesity and unburdens the family by framing the problem in a different light,” Dr. Kelly stressed.
Dr. Frithioff-Bøjsøe has reported no relevant financial relationships. Dr. Holm has an obesity management company called Holm. Dr. Kelly serves as an unpaid consultant for Novo Nordisk, Vivus, Eli Lilly, and Boehringer Ingelheim and receives donated drug/placebo from Vivus for a clinical trial funded by the National Institutes of Health.

Calorie counting and exercise ‘of limited value’ for obesity weight loss
Counting calories, joining a gym, and taking part in exercise programs are popular methods used by people in the United Kingdom who want to shed some pounds, but they seem to be fairly ineffective strategies, according to an investigation.
A survey of adults with obesity from six countries in western Europe found that most who set out to reduce a meaningful amount of weight failed in their attempt.
The preliminary results, presented in two posters at the European Congress on Obesity, underlined the need for better support and solutions for weight management, the authors suggested.
Marc Evans, MB, BCh, a consultant physician in diabetes and endocrinology, from University Hospital, Cardiff, Wales, who led the analysis, said that, “while obesity’s impact on health is well known, our finding that a sizable proportion of adults with obesity appear at elevated risk of hospitalization or surgery due to multiple underlying illnesses, undoubtedly adds a sense of urgency to tackling Europe’s growing obesity epidemic.”
The study, which also involved analytics consultancy firm Lane Clark & Peacock, conducted a cross-sectional survey of 1,850 adults. Of those 500 were from the UK, and the remainder from France, Germany, Italy, Spain, and Sweden.
All participants had a body mass index of 30 kg/m2, or higher. More specifically, 56.3%; were classified as obesity class I, 26.8% obesity class II, and 16.9% obesity class III.
Obesity-related conditions
In total, 25.7% of participants reported no obesity-related health conditions, 28.4% had one condition, 19.6% had two, and 26.3% had three or more. The most common comorbidities were hypertension, dyslipidemia, and type 2 diabetes.
Overall, 78.6% of respondents reported having tried to lose weight in the previous year. Asked in a questionnaire about how they had tried to achieve this, the responses indicated that the most common strategies were:
- Calorie-controlled/restricted diet (71.9%)
- Exercise program course (21.9%)
- Pharmaceutical treatment/medication (12.3%)
- Joined a gym (12%)
- Digital health app (9.7%)
Among other participants, 8.1% said they had used alternative treatments, 7.6% a weight loss service, and 2.1% cognitive-behavioral therapy.
Analysis of the survey results showed that 78% of the individuals who attempted to lose weight did not achieve a clinically meaningful loss of 5% or more of their body weight, while some actually weighed more afterward.
Exercise and restricted diet
Notably, while exercise and calorie-controlled or restricted diets were among the most popular weight-loss methods in U.K. participants, they were amongst the least successful strategies. For instance, while 26.5% of adults who controlled their diet said they had lost weight, 17.1% reported their weight had increased. For those who took part in an exercise program, 33.3% said they lost weight, but 15.5% said they gained weight.
Signing up for gym membership also scored poorly, with 27% shedding weight, compared with 32.4% who put weight on.
“Our survey results indicate that, while the majority of adults with obesity are actively trying to reduce their weight, using a variety of strategies, most are unsuccessful,” said Dr. Evans.
Further studies were needed to assess whether people who lose weight succeed in maintaining their weight loss, the authors said.
The conference posters have yet to be published in a journal but were peer reviewed by the ECO selection committee.
The studies were sponsored by Novo Nordisk, a researcher into and manufacturer of diabetes and obesity medications, and employer of several of the coauthors.

CDC flags uptick in hypertensive disorders in pregnancy
Hypertensive disorders in pregnancy affect nearly 16% of women who give birth in U.S. hospitals and appear to be increasing, according to an April 29 report from the Centers for Disease Control and Prevention.
Older patients and Black women are substantially more likely to experience hypertension in pregnancy, the analysis found.
“Addressing hypertensive disorders in pregnancy is a key strategy in reducing inequities in pregnancy-related mortality,” study coauthor Wanda Barfield, MD, MPH, director of CDC’s Division of Reproductive Health, said in a statement.
Age, obesity, diabetes
The overall prevalence of hypertensive disorders in pregnancy increased from 13.3% in 2017 to 15.9% in 2019, the researchers reported in the CDC’s Morbidity and Mortality Weekly Report.
The uptick in hypertension coincides with trends toward older maternal age and higher rates of obesity and diabetes, which may explain the increase, they said.
For the study, Dr. Barfield and her colleagues analyzed nationally representative data from the National Inpatient Sample. They identified patients with a diagnosis of chronic hypertension, pregnancy-associated hypertension, or unspecified maternal hypertension during their hospitalization.
Among women aged 45-55 years, the prevalence of hypertension was 31%. Among those aged 35-44 years, it was 18%.
Hypertension diagnoses were more common in women who were Black (20.9%) or American Indian or Alaska Native (16.4%), than in other groups.
Of patients who died during delivery hospitalization, 31.6% had a hypertensive disorder.
The study shows a marked increase in hypertensive disorders over a relatively short time, according to Jane van Dis, MD, of the department of obstetrics and gynecology at the University of Rochester (N.Y.), who was not involved in the research. The phenomenon is consistent with her own experience, she said.
“When I am admitting patients, I’m oftentimes surprised when someone does not have a hypertensive disorder because I feel like the majority of patients these days do,” Dr. van Dis told this news organization.
Dr. Van Dis speculated that factors related to the environment, including air pollution and endocrine disrupters, could contribute to elevated rates of hypertensive disorders.
Natalie Bello, MD, MPH, director of hypertension research at Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles, said rates of hypertension today could be even higher than in the study.
The CDC report relied on pre-COVID data, and the pandemic “increased disparities in health outcomes,” Dr. Bello said in an interview. “I’m worried that in actuality these numbers are an underestimation of the current state of hypertension in pregnancy.”
Dr. Bello, who has studied the need for better training in cardio-obstetrics, applauded Vice President Kamala Harris’ efforts to improve maternal health.
“The racial and geographic disparities that we continue to see in the field are disheartening but should be a call to action to redouble our work to improve maternal outcomes,” Dr. Bello told this news organization. “The good news is that a lot of morbidity related to hypertension can be avoided with timely diagnosis and treatment of blood pressure. However, we need to act to provide all pregnant persons with optimal care.”
Janet Wright, MD, director of CDC’s Division for Heart Disease and Stroke Prevention, said blood pressure home monitoring is a “great example” of a strategy clinicians can use to identify and manage patients with hypertension.
But one approach – self-monitoring blood pressure from home during pregnancy – did not significantly improve the health of pregnant women, according to new results from randomized trials in the United Kingdom.
Trial results published in JAMA show that blood pressure home-monitoring coupled to telemonitoring, as compared with usual care, did not significantly improve blood pressure control among patients with chronic or gestational hypertension.
A second trial published in JAMA that included patients at risk for preeclampsia found that self-monitoring with telemonitoring did not lead to significantly earlier diagnoses of hypertension.
“Individuals at risk for a hypertensive disorder of pregnancy, or with gestational or chronic hypertension, cannot be treated with a single approach,” Malavika Prabhu, MD, with Weill Cornell Medicine, New York, and coauthors write in an editorial accompanying the JAMA studies. Although the data suggest that self-monitoring of blood pressure is practical and tolerated, “More research is needed to determine optimal, high-value, equitable approaches to averting adverse perinatal outcomes associated with hypertensive disorders of pregnancy,” they write.
The CDC study authors and Dr. van Dis have disclosed no relevant financial relationships. Dr. Bello is funded by the National Institutes of Health to study blood pressure monitoring in pregnancy. The JAMA editorial authors disclosed university, government, and corporate grants and work with publishing companies.

New research holds promise for fighting obesity, says expert
Caroline Apovian, MD, codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital, described some of the new insights about obesity she has gained during her talk at the annual meeting of the American College of Physicians.
“When I was a medical student a while back, I learned that fat tissue just sat there and stored fat,” she said. “Now we know it’s an endocrine organ.”
This tissue secretes hormones, such as leptin, and other factors that have an array of effects on the brain, pancreas, heart, liver, and muscles. Moreover, it has plasticity, with the ability to change, constantly adjusting our metabolism as nutrient supply and demand changes, she continued.
Obesity leads to a decline in this plasticity, leading to fibrosis and inflammation and other problems. These changes can further impair the function of adipose tissue, leading to metabolic disease. But the central role of adipose tissue, and its dynamic nature, presents an opportunity for treatment, Dr. Apovian said, during her talk.
Hints to why obesity has become more common
More than 42% of the U.S. population – “unbelievably,” Dr. Apovian said – is obese, meaning they have a BMI over 30, according to the Centers for Disease Control and Prevention. That’s up by about 25% since 1960, although calories eaten hasn’t increased, and physical activity has increased somewhat, she said.
The root cause is still a bit of a mystery, but according to “good hints and clues” from animal models that are starting to be translated to the study of human obesity, “it has to do with epigenetics and how our brains and our bodies are perceiving the environment,” she noted, during her presentation.
“Our genes haven’t changed. Our environment has changed,” she said.
The industrialization of the food supply, the use of pesticides and preservatives, the dawn of fast food have all combined, most likely, to do “a number on our bodies,” Dr. Apovian said.
But not all hope is lost thanks to new research, Dr. Apovian suggested.
New treatments show promise for helping patients’ obesity
New research that has increased Dr. Apovian’s understanding of the sophisticated role of adipose tissue may be helpful for treating patients with obesity, offering more targets for intervention, she told the audience.
Some treatment avenues already identified have started producing results, Dr. Apovian noted.
Gastric bypass surgery typically leads to a loss of 25% of body weight, but is often shunned by patients, she said. “With such a great surgical procedure, we still only do 256,000 procedures and we have millions of Americans with a BMI over 30.”
Weight control with obsessive dieting, meal-planning and calorie-counting, “can be done, but it’s really hard,” Dr. Apovian noted.
More appealing therapies targeting hormones and appetite suppression have produced impressive results. Recently approved semaglutide produced 14% weight loss, compared with about 2% for placebo, she said.
Results just released for tirzepatide, a dual agonist of gut hormones GLP-1 and GIP, show a 22% total weight loss, compared with about 2% for placebo, with about 56% of patients losing more than 20% of their body weight, Dr. Apovian said.
Referencing studies finding that several hormones are altered during weight loss, she predicted that targeting multiple hormones with drug treatment will also be necessary for best results.
But, she noted, “we’re treating obesity now with one- or two-drug combos.”
Medication costs are too high for many patients
Isis Smith, MD, an internist at University Medical Center in New Orleans, said in an interview that the cost of the most effective medications – which are not covered by Medicaid – means that many of her patients don’t have access to these treatments.
“We’re talking about $1,000 a month. And so there is no way they can afford [them]. I can prescribe phentermine [but] unless a patient has another indication, Medicaid will not pay for it,” she explained.
“I love hearing about all of the new developments. ... It’s interesting to hear, but we need to get insurance to pay so that I can actually prescribe,” Dr. Smith noted.
Dr. Apovian reports financial relationships with Xeno Biosciences, Cowen, Allergan, Novo Nordisk, Abbott Nutrition, and other companies.

The industrialization of the food supply, the use of pesticides and preservatives, the dawn of fast food have all combined, most likely, to do “a number on our bodies,” Dr. Apovian said.
But not all hope is lost thanks to new research, Dr. Apovian suggested.
New treatments show promise for helping patients’ obesity
New research that has increased Dr. Apovian’s understanding of the sophisticated role of adipose tissue may be helpful for treating patients with obesity, offering more targets for intervention, she told the audience.
Some treatment avenues already identified have started producing results, Dr. Apovian noted.
Gastric bypass surgery typically leads to a loss of 25% of body weight, but is often shunned by patients, she said. “With such a great surgical procedure, we still only do 256,000 procedures and we have millions of Americans with a BMI over 30.”
Weight control with obsessive dieting, meal-planning and calorie-counting, “can be done, but it’s really hard,” Dr. Apovian noted.
More appealing therapies targeting hormones and appetite suppression have produced impressive results. Recently approved semaglutide produced 14% weight loss, compared with about 2% for placebo, she said.
Results just released for tirzepatide, a dual agonist of gut hormones GLP-1 and GIP, show a 22% total weight loss, compared with about 2% for placebo, with about 56% of patients losing more than 20% of their body weight, Dr. Apovian said.
Referencing studies finding that several hormones are altered during weight loss, she predicted that targeting multiple hormones with drug treatment will also be necessary for best results.
But, she noted, “we’re treating obesity now with one- or two-drug combos.”
Medication costs are too high for many patients
Isis Smith, MD, an internist at University Medical Center in New Orleans, said in an interview that the cost of the most effective medications – which are not covered by Medicaid – means that many of her patients don’t have access to these treatments.
“We’re talking about $1,000 a month. And so there is no way they can afford [them]. I can prescribe phentermine [but] unless a patient has another indication, Medicaid will not pay for it,” she explained.
“I love hearing about all of the new developments. ... It’s interesting to hear, but we need to get insurance to pay so that I can actually prescribe,” Dr. Smith noted.
Dr. Apovian reports financial relationships with Xeno Biosciences, Cowen, Allergan, Novo Nordisk, Abbott Nutrition, and other companies.

Vegetarian diet as good for children, with slight risk of underweight
With more families placing their children on vegetarian diets, the results from a Canadian longitudinal cohort study are reassuring: It found no clinically meaningful differences in height, growth, or biochemical measures of nutrition in young children on vegetarian and nonvegetarian diets.
While z scores (the standard deviation above or below the mean) were similar in both dietary groups, there was a weak association between a vegetarian diet and lower mean z height, as well as slightly higher odds of underweight.
No significant associations were identified between vegetarian and nonvegetarian diets for child z body mass index (BMI), serum ferritin, 25(OH)D, and serum lipids, according to Jonathon L. Maguire, MD. MSc, of St. Michael’s Hospital Pediatric Clinic in Toronto.
Moreover, the magnitude of the height and vegetarian diet association was small at just 0.3 cm for a 3-year-old child and unlikely to be clinically meaningful, Dr. Maguire and colleagues wrote online in Pediatrics.
In a secondary study outcome, cow’s milk consumption was associated with higher serum lipid levels for both diets. Serum lipids were similar among those who did or did not consume a vegetarian diet and consumed the recommended 2 cups of cow’s milk per day.
“The vast majority of children with vegetarian diets have similar growth and nutrition as children without vegetarian diets,” said Dr. Maguire, who is also a professor of pediatrics and nutritional sciences at the University of Toronto, in an interview. “But, I think we should be mindful to carefully plan vegetarian diets for children [who are] underweight.”
The study conclusion was based on 8,907 children, 6 months to 8 years of age, including 248 vegetarian and 25 vegan children, at baseline. They were part of theTARGet Kids! practice-based research network in Toronto.
The mean age of children at baseline was 2.2 years (standard deviation, 1.5), and 52.4% were male. Participants were followed for an average of 2.8 years (SD, 1.7).
Those with a vegetarian diet had longer breastfeeding duration: 12.6 months (SD, 9.5) versus 10.0 months (SD, 7.0). They were also more likely to be of Asian ethnicity: 33.8% versus 19.0%. Otherwise, children with and without a vegetarian diet were similar at baseline.
In study outcomes, vegetarian children had higher odds of underweight: body mass index z score less than –2 (odds ratio 1.87; 95% confidence interval, 1.19-2.96, P = .007), while no association with overweight or obesity was found.
In a secondary outcome, cow’s milk consumption was associated with higher levels of non–high-density lipoprotein cholesterol (P = .03), total cholesterol (P = .04), and low-density lipoprotein cholesterol (P = .02) in young children on a vegetarian diet. Levels were similar in children with and without a vegetarian diet who consumed the recommended 2 cups of cow’s milk per day.
Previous studies have found that vegetarian children have normal growth and development but tend to be leaner than their omnivore peers.
As for the potential effect of following a fully vegan diet on these nutritional measures, Dr. Maguire said, “Unfortunately, there were not enough children with vegan diets to make meaningful conclusions.”
Would results likely be similar in older children who have more independence and engage more with their peers?“ I don’t know, but we will be following these children for many years to come through the TARGet Kids! research network, Dr. Maguire said.
Studies such as this are timely as plant-based eating becomes more widespread in the United States. The 2007-2010 National Health and Nutrition Examination Surveys found that 2.1% of American adults followed a vegetarian diet, and that figure appears to have increased, with 5% of American adults self-identifying as vegetarian in a 2019 Gallup poll.
Offering her perspective on the Canadian study but not involved in it, Stephanie Di Figlia-Peck, MS, RDN, agreed the results indicate that “a vegetarian diet is not a negative thing for growth and development.” She is a lead registered dietitian in the division of adolescent medicine at Cohen Children’s Medical Center in New Hyde Park, N.Y. She noted, however, that the study looked only at very young children on average.
She stressed that vegetarian regimens require family commitment and agreed on the need for planning. “For these diets to work, a lot has to go into it. But if they’re carefully planned, there is adequate protein and micro- and macronutrients and there’s a nonnegative effect on growth and development.”
The study results mirror what she sees in clinical practice, with vegetarian children tending to weigh less. “Some obese and overweight children will adopt vegetarian diets to lose weight,” Ms. Di Figlia-Peck said.
And perseverance has rewards. “When people follow a vegetarian diet, they tend to have lower blood pressure and cholesterol. A plant-based diet can favorably impact diseases for an entire lifetime.”
This study was supported by the Canadian Institutes of Health Research and the St. Michael’s Hospital and SickKids Hospital foundations. Dr. Maguire received an unrestricted research grant for a previous investigator-initiated study from Dairy Farmers of Canada, and D drops provided nonfinancial support (vitamin D supplements) for a previous investigator-initiated study on vitamin D and respiratory tract infections. Coauthor David Jenkins, MD, PhD, DSc, reported research support from multiple private-sector and nonprivate organizations; several of his family members are involved in the promotion of vegetarian diets. Ms. Di Figlia-Peck had no competing interests to declare.
