Adjusted for age, race/ethnicity, parity, smoking and prenatal vitamin use. Adjusted mean values reported for MODEL 1 are from a regression model based on the entire study cohort (N = 3,373) with indicators variables specified to represent Non-Hispanic white, nulliparous, non-smoking women from 25–34 years of age.
Adjusted for age, race/ethnicity, parity, smoking, prenatal vitamin use, and pre-pregnancy body mass index. Adjusted mean values reported for MODEL 2 are from a regression model based on the entire cohort (N = 3,373) with indicators variables specified to represent Non-Hispanic white, nulliparous, non-smoking women from 25–34 years of age, with a pre-pregnancy BMI < 25 kg/m2.
