Unadjusted values are means ± SDs; adjusted values are means ± SEs. BMIZ, BMI-for-age z score; IFA, iron and folic acid; LAZ, length-for-age z score; LNS, lipid-based nutrient supplement for pregnant and lactating women; MUAC, midupper arm circumference; WAZ, weight-for-age z score.
P values are based on ANCOVA (PROC MIXED; SAS Institute) accounting for union and the random effect of cluster and controlling for selected covariates in adjusted models. Intracluster correlation was zero for the primary outcomes.
Adjusted for maternal education, assets quintile, time interval (season) at birth, maternal height, maternal BMI, child sex, food-security category, parity, gestational age at enrollment (imputed), and accounting for union and the random effect of cluster.
