†Adjusted for maternal age, BMI, education, smoking, parity, child’s sex and gestational age at birth. Models with birthweight z-scores as outcome were not adjusted for sex or gestational age. Stratified models were not adjusted for sex.
‡Results are derived from the stratified WQS model allowing for sex-specific weights and including the interaction term WQS*sex (p-valueint).
