In the primary model the numbers of participants were n = 1111 for all birth-weight models, n = 1092 for all birth-length models, and n = 1091 for all head-circumference models. All models adjusted for maternal age, gestational age, child sex, maternal BMI, parity, alcohol use in pregnancy, and socioeconomic status. LC-PUFA, long-chain PUFA; MeHg, methylmercury.
