title: Nutrition education and mega-dose vitamin A supplementation in Nepal.
abstract: Two approaches to improve vitamin A nutriture are compared: nutrition education and mega-dose capsule distribution. The impact of these programmes on vitamin A deficiency (VAD), wasting malnutrition, and excessive childhood mortality are compared for approximately 40,000 children who were assigned to either intervention cohorts or a control group from 75 sites within seven districts in two ecological settings (Terai, or lowland, and hills) of Nepal. Twenty-four months after the implementation of the project, the reduction of risk of xerophthalmia was greater among children of mothers who were able to identify vitamin A-rich foods [relative risk (RR) = 0.25; 95% CI = 0.10-0.62] than among children who received mega-dose capsules (RR = 0.59; 95% CI = 0.41-0.84). The risk of mortality at two years was reduced for both the nutrition education cohort (RR = 0.64; 95% CI = 0.48-0.86) and capsule distribution cohort (RR = 0.57; 95% CI = 0.42-0.77). The nutrition education program, however, was more expensive to deliver than the capsule distribution programme. High rates of participation in the supplementation programme were achieved within a short period. The nutrition education message spread rapidly throughout the study population, although practice was slower to change. Where maternal literacy was low and channels of communication were limited, the capsule programme appeared to be more cost-effective. However, economies of scale for nationwide programmes exist for nutrition education programmes that do not exist for capsule distribution programmes. A comprehensive national programme requires both dietary supplementation and nutrition education.
