Objectives: This study assessed the effect of vitamin A supplementation at 6-month intervals on child growth.
Methods: Sudanese children (n = 28,740) 6 to 72 months of age were weighed and measured at baseline and at each of three follow-up visits.
Results: Periodic vitamin A supplementation had no effect on the rate of weight or height gain in the total population or on the incidence of wasting, stunting, or wasting and stunting among children who were normally nourished at baseline.
Conclusions: Reducing poverty and improving access to adequate diets should remain the goals of programs designed to improve the nutritional status of malnourished populations.
