The observed effect of zinc supplementation on diarrheal morbidity varies between trials and there is a need to identify subgroups most likely to benefit from improved zinc nutriture. In a randomized, double-blind trial in 2296 children in New Delhi, India, we assessed whether baseline cobalamin or folate status modified the effect of zinc supplementation on the incidence of prolonged (>= 7 d duration) and acute diarrhea. Children aged 6-30 mo received zinc or placebo daily for 4 mo. We measured plasma concentrations of folate, cobalamin, total homocysteine (tHcy), and methylmalonic acid (MMA) at enrollment and assessed the efficacy of zinc supplementation in subgroups based on these variables. The efficacy of zinc on reducing the risk of prolonged diarrhea was higher in those with plasma cobalamin concentrations below the 25th percentile and in those with tHcy and MMA concentrations above the 75th percentile. The OR (95% Cl) for children below and above the 25th percentile for cobalamin were 0.53 (0.35-0.78) and 0.90 (0.73-1.11), respectively (P-interaction = 0.015). There were similar differences for the OR when comparing efficacy in those above and below the 75th percentile for tHcy and MMA (P-interaction = 0.045 and 0.188, respectively). Baseline folate status did not modify the effect of zinc on prolonged diarrhea. Neither cobalamin nor folate status influenced the effect of zinc on acute diarrhea. Children with poor cobalamin status benefited more from zinc supplementation for the prevention of prolonged diarrhea J. Nutr. 141: 1108-1113, 2011.
