Abstract

We conducted a randomized, double-blind placebo controlled, community trial in rural Bangladesh in children 4-59 mo of age to compare the efficacy of a 5- and 10-d course of zinc therapy on the incidence and duration of diarrhea over the subsequent 90-d follow-up after initial treatment for an acute childhood diarrheal (ACD) episode. Children (n = 1622) with ACD were randomly allocated to either 5 or 10 d of zinc treatment. Female field workers visited each child daily, supervised the administration of zinc, recorded the duration of current episode, and the occurrence and duration of diarrhea over the subsequent 3mo. The incidence of diarrhea over the 90 d of follow-up did not differ between the 5-d (1.08 ± 1.38 episodes) and 10-d (1.02 ± 1.35 episodes) groups (P = 0.35). Children in both groups experienced a comparable duration of diarrheal episodes (3.1 ± 5.6 d vs. 2.9 ± 5.6 d, 5-d vs. 10-d, respectively; P = 0.64) with a mean difference between groups within the defined range of equivalence. Time to onset of the first episode and the proportion children experiencing diarrhea during the 90-d follow-up also did not differ between groups. These findings suggest that among Bangladeshi children, a 5-d zinc treatment for ACD is as efficacious as 10 d in preventing diarrhea in the subsequent 3 mo.
