Abstract:
During a countrywide survey, we assessed the prevalence of vitamin A deficiency by impression cytology method with transfer in a randomized sample of 650 representative of the children's population of the Republic of Malawi. A vitamin A deficiency was indicated by the results of the ophthalmic examination (XN = 1,4%; X2 = 0,2%) and the ICT test (22% with deficient cytology). Results of ICT were related to age. Vitamin A deficiency seems to be a public health problem in the Republic of Malawi.
