Between 1994 and 1997, a community-randomized, placebo-controlled trial was conducted in the Sarlahi district of Nepal to assess the impact on maternal and infant health and survival of weekly vitamin A or beta-carotene supplementation among 44 646 women of childbearing age. Distributors spent an average of 5 hours per week delivering supplements. The mean coverage rate among the 345 distributors was 61% (range: 16% to 86%).
