OBJECTIVE: To identify factors associated with mental and psychomotor development of infants enrolled at public day care centers of Recife, Pernambuco, Brazil. METHODS: This is a cross-sectional study conducted with 108 infants aged four to 24 months attending four public day care centers of the Municipality of Recife from February to April 2005. Mental and psychomotor development was assessed by the Bayley Scale of Infant Development II. Family socioeconomic and demographic conditions and infant biological characteristics at birth (weight, sex and gestational age) were obtained by maternal interview. Nutritional status was assessed by the indexes "weight-for-age", "length-for-age" and "weight-for-length" and by hemoglobin level. RESULTS: Mean mental and psychomotor development indexes were 88±11 and 95±12, respectively. Gestational age showed significant association with mental and psychomotor development. Birthweight and current nutritional status assessed by "weight-for-length" were associated with psychomotor development. CONCLUSIONS: Mental and psychomotor development were in the the normal range, but, below the expected for infants of the same age group of reference populations in developed countries. The factors associated with poor developmental indexes in this population are related to biological factors, with emphasis on nutritional deficits. Their reduction should be a priority for health and educational policy managers.
