All models are adjusted for maternal age, BMI before pregnancy, maternal education level, prenatal vitamin use, annual household income, maternal ethnicity, gestational age, infant sex, and neighborhood SES z-sum (the sum of the z-scores for median household income, percent of households with interests, dividends, or rent income, percent of residents with high school diploma, percent with college degree, percent with professional occupation, and median value of owner-occupied housing units).
