Vitamin A deficiency is a severe condition particularly in malnourished children and women in developing countries.1,2 It has been estimated that approximately 250 000 to 500 000 malnourished children go blind each year from a deficiency of vitamin A, approximately half of whom die within a year of becoming blind. The most recent survey data obtained from 8 state surveys in 2003 suggest that 62% of preschoolers in India are vitamin A deficient, having serum retinol concentrations lower than 20 μg/dL (to convert to micromoles per liter, multiply by 0.0349).3 Against this background of rural deficiency, we conducted this study to assess the prevalence of symptoms of vitamin A deficiency in schoolchildren in urban central India.
