TOPLINE:
Higher high-density lipoprotein cholesterol (HDL-C) levels show a positive association with prediabetes reversal to normoglycemia in Chinese adults, but only up to a certain threshold.
METHODOLOGY:
- Researchers examined the correlation between HDL-C levels and the reversion of people with prediabetes to normoglycemia in a secondary analysis of data from a population-based cohort study.
- The analysis included 15,420 Chinese patients with prediabetes who underwent health screening between 2010 and 2016 (mean age, 51 ± 13 years; 5414 (35%) women).
- The outcome measure, reversion to normoglycemia, was determined by no self-reported diabetic event and fasting plasma glucose < 5.6 mmol/L at follow-up.
- They categorized the adults into four groups on the basis of HDL-C quartiles.
- They used multiple statistical models to investigate the association between HDL-C levels and reversion from prediabetes, assess the linearity of the association, and account for independent variables and confounding factors.
TAKEAWAY:
- After a median follow-up of nearly 3 years, 6627 (43%) of patients with prediabetes had a reversion to normoglycemia.
- The groups with higher HDL-C levels had a higher likelihood of prediabetes reversal to normoglycemia (adjusted hazard ratio [HR], 1.90; P < .001).
- They found a nonlinear association and threshold effect: The probability of reversal from prediabetes to normoglycemia stabilized rather than continued to increase at an inflection point (1.54 mmol/L in men, 1.62 mmol/L in women).
- A significant positive correlation with reversal to normoglycemia was observed below the HDL-C threshold (men: HR, 2.78; 95% CI, 2.37-3.26; women: HR, 2.22; 95% CI, 1.80-2.73).
IN PRACTICE:
“Keeping HDL-C levels near the inflection point in patients with prediabetes may greatly increase the likelihood of reversion from prediabetes to normoglycemia,” the authors wrote.
SOURCE:
The study, with lead author Zihe Mo, Department of Physical Examination, Dongguan Tungwah Hospital, Dongguan, China, was published online in Scientific Reports.
LIMITATIONS:
The study included individuals of Chinese descent, necessitating more studies into the HDL-C and normoglycemia relationship across diverse genetic backgrounds. The study relied solely on fasting plasma glucose measurements and was unable to capture the entirety of prediabetes complexity. As a secondary analysis of previously published data, the study faces limitations in managing unmeasured variables not initially included in the dataset. The observational study cannot determine a causal relationship between HDL-C and reversion from prediabetes to normoglycemia.
DISCLOSURES:
The study was supported by the Natural Science Funding of China. The authors declared no conflicts of interest.
