Bold signifies p < 0.05.
MDI: mental development index, PDI: psychomotor development index, BRS: behavioral rating scale.
Model 1 of 6 months adjusted for baseline characteristics (maternal age, maternal education, log income, parity, maternal BMI, birth weight), age at BSID assessment on 6 months, weight of infants at 6 months, and HOME score at 6 months. For Model 1 of 24 months, baseline characteristics plus age at BSID assessment on 24 months, weight of infants at 24 months, and HOME score at 6 months were adjusted. For Model 1 of 36 months, baseline characteristics plus age at BSID assessment on 36 months, weight of infants at 36 months, and HOME score at 36 months were adjusted. Model 2 of all months adjusted Model 1 plus log As.
