  1. The adjusted model for wasting at 6 months controlled for season of birth, season of visit, maternal short stature, maternal age, and household wealth. The adjusted model for wasting at 24 months controlled for child sex, season of birth, season of visit, breastfeeding status, maternal literacy, paternal literacy, maternal short stature, maternal BMI, maternal low MUAC, whether the household was from a nomadic pastoralist tribe, and household wealth. The adjusted model for stunting at 6 months controlled for child sex, paternal literacy, maternal short stature, maternal BMI, number of children in the household, whether household was from a nomadic pastoralist tribe, and household wealth. The adjusted model for stunting at 24 months controlled for child sex, breastfeeding status, maternal literacy, paternal literacy, maternal short stature, maternal BMI, maternal low MUAC, maternal age, whether household was from a nomadic pastoralist tribe, and household wealth
