, a population-based prospective cohort study shows.
METHODOLOGY
- Investigators analyzed data from a large cohort of singleton children with insurance born in Kaiser Permanente Southern California hospitals between 2001 and 2014.
- They ascertained ASD diagnosis, maternal race and ethnicity, and maternal address at time of birth.
- Neighborhood disadvantage was determined by the percentage of families in the mother’s neighborhood considered to be living in poverty, unemployed, have female-headed households with children, using public assistance, less than a high school education, among other variables.
TAKEAWAY
- Among 318,300 mothers who delivered babies during the study period, 6350 children were diagnosed with ASD during follow-up, and median age at diagnosis was 3.5 years.
- Greater neighborhood disadvantage at birth was associated with a higher likelihood of ASD diagnosis (adjusted hazard ratio [aHR], 1.07; 95% CI, 1.02-1.11)
- ASD diagnoses were more likely among children of mothers who were Black (aHR, 1.13; 95% CI, 1.02-1.25), Asian/Pacific Islander (aHR, 1.11; 95% CI, 1.02-1.20), or Hispanic (aHR, 1.07; 95% CI, 1.00-1.15), even after the researchers controlled for neighborhood.
- While odds of an ASD diagnosis were higher among children from minority racial and ethnic groups, neighborhood disadvantage was significantly associated with ASD diagnosis only for children of White mothers (aHR, 1.17; 95% CI, 1.09-1.26).
IN PRACTICE
Investigators noted that they could only speculate about the factors driving the association between neighborhood disadvantage and a stronger risk for ASD diagnosis in children of White mothers. “They may be due to systemic racism, discrimination, and their impact on maternal health during pregnancy,” they wrote.

Xin Yu, MS, and Daniel Hackman, PhD, of the University of Southern California Los Angeles, led the study, which was published online November 15 in JAMA Psychiatry.
LIMITATIONS
The research was limited by a lack of information on fathers and variables such as incomes, which may have confounded the findings. The authors also acknowledged that the study should be replicated in other health service settings.
DISCLOSURES
The study was funded by the National Institutes on Environmental Health Sciences, the National Institutes of Health (NIH), and the Environmental Protection Agency. Dr. Hackman reported receiving grant funding from NIH during the conduct of the study. Other disclosures are available in the original study.
