About The Study: In this cohort study, both prenatal depression and gestational diabetes were associated with childhood obesity risk, with larger effect sizes observed for gestational diabetes. Children exposed to both conditions had the greatest risk, although associations appeared additive rather than synergistic. These findings underscore the need for universal prenatal screening and risk stratification, along with targeted interventions for children exposed to these conditions.
