Adjusted for age, race/ethnicity, smoking, and pre-pregnancy body mass index. Adjusted mean values reported 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 25–34 years of age, with a pre-pregnancy BMI <25 kg/m2.

Adjusted for age, race/ethnicity, parity, smoking and pre-pregnancy body mass index. Adjusted mean values reported are from a regression model based on nulliparous women only (N = 2,146) with indicators variables specified to represent Non-Hispanic white, nulliparous, non-smoking women 25–34 years of age, with a pre-pregnancy BMI <25 kg/m2.

Adjusted for age, race/ethnicity, parity, smoking and pre-pregnancy body mass index. Adjusted mean values reported are from a regression model based on multiparous women only (N = 1,227 with indicators variables specified to represent Non-Hispanic white, nulliparous, non-smoking women 25–34 years of age, with a pre-pregnancy BMI <25 kg/m2.
