Tóm tắt :

273-279 To determine vitamin A status using conjunctival impression cytology [CIC] in children aged 2- 5 years, we assessed 1257 randomly selected children in urban and rural areas of Tehran. History of using supplemental vitamin A, respiratory or diarrhoeal infection in the previous 6 months, residential location, parents' education, family economic status, and child's age, sex and weight were recorded. Sub- clinical vitamin A deficiency [defined as abnormal CIC] was found in 23.6% of the sample, a rate classified as a moderate public health problem. There was a statistically significant relationship, between sex and age and abnormal CIC [P < 0.05]
