Estimated effects (β) with 95% confidence intervals (CI) are shown for a 1-SD increase in adipokines. Weight change was defined as the difference in weight between birth and 6 months (kg). The sex-specific weight-for-age z-score calculated based on CDC 2000 growth chart. Models were adjusted for maternal age, gestational age, race/ethnicity, sex (where appropriate), parity, maternal pre-pregnancy BMI, and
birthweight as indicated. Pinteraction tests effect modification of sex. Sample sizes for males/females were HMW adiponectin (n=23/23), leptin (n=22/23), and leptin / HMW adiponectin (L/A) ratio (n=22/23).
