*Adjusted for maternal HIV status (0 = negative; 1 = positive), PBF at Month 6 (0 = no breastfeeding or partial breastfeeding; 1 = predominant breastfeeding or exclusive breastfeeding), Maternal Cryptosporidium infection at Month 1 (0 = uninfected; 1 = infected), animal ownership (0 = no animals; 1 = owns animals), hand washing (0 = mother doesn't wash hands prior to infant feeding; 1 = mother washes hands prior to infant feeding), wealth (0 = lower 2 tertiles; 1 = top tertile), and maternal literacy (0 = mother cannot read; 1 = mother can read).

OR = odds ratio; CI = confidence interval; EBF-WHO = WHO definition of exclusive breastfeeding; PBF = exclusive or predominant breastfeeding; Washes hands = mother's self report of washing hands prior to feeding infant; Wealth = index (0–10) calculated by summing a categorical list of household possessions and then stratified into wealth (top tertile) vs. not wealthy (lower 2 tertiles); maternal literacy = mother's self-report that she can read.
