Children born to women who have high blood levels of lead are more likely be overweight or obese, compared to those whose mothers have low levels of lead in their blood, according to a study funded by the National Institutes of Health and Health Resources and Services Administration. The study was conducted by Xiaobin Wang, M.D., of the Johns Hopkins Bloomberg School of Public Health in Baltimore, and colleagues. It appears in JAMA Network Open.
Researchers analyzed data on 1,442 mother-child pairs from the Boston Birth Cohort <https://clinicaltrials.gov/ct
