Key Points Question Is there an association between neighborhood-level measures of opportunity and social vulnerability in early life and trajectories of body mass index (BMI) and obesity risk from birth to adolescence? Findings In this cohort study including 20 677 US children, residence in neighborhoods with higher-opportunity or lower social vulnerability in early life, especially at birth, was associated with a lower mean BMI trajectory and a lower risk of obesity from childhood to adolescence. Meaning These findings suggest that residence in higher-opportunity neighborhoods in early life may promote maintenance of favorable BMI patterns during childhood.
