Abstract
Retinol was determined spectrophotometrically in the blood of 291 mothers at delivery and in the umbilical cord of the newborn. The mothers came from different socioeconomic strata in Rio de Janeiro. Levels of retinol were determined using spectrophotometry (Bessey et al). The circulation levels of retinol were low (below 1.05 micromol/L) in 22.0% of the mothers and in 54.2% of the newborn. A close association was found between low levels in the mothers' serum and those in the children's umbilical cord (p <0.0001). There was no association between maternal vitamin A deficiency (DVA) and socioeconomic stratum, family income or level of education. DVA is a distressing health problem among mothers and newborns and its diagnosis must be included in antenatal care. This reinforces the concept that intervention programs must emphasize changes in feeding practices and focus on the most vulnerable groups, of which pregnant women warrant special attention, regardless of socioeconomic stratum.

Summary
REJANE ANDRÉA RAMALHO*, HERNANDO FLORES, ELIZABETH ACCIOLY, CLÁUDIA SAUNDERS Trabalho realizado pelo grupo de pesquisa em vitamina A do Instituto de Nutrição Josué de Castro da Universidade Federal do Rio de Janeiro, Rio de Janeiro, RJ. Investigou-se a associação entre deficiência de vitamina A (DVA) e condições sociodemográficas em 291 puérperas de diferentes estratos socioeconômicos e seus respectivos recém-nascidos (RN), atendidos em uma maternidade pública do município do Rio de Janeiro, Brasil. Objetivou-se, no presente estudo, avaliar a associação entre o estado nutricional de vitamina A e as condições sociodemográficas de mães e RN, atendidos em maternidade pública do município do Rio de Janeiro, Brasil. Não foi evidenciada associação significativa entre o estado nutricional de vitamina A do binômio mãe-filho com as variáveis idade materna, grau de escolaridade materna e renda familiar per capita. Entre os RN, a média dos níveis de retinol no sangue de cordão foi 0,98 mmol/L (DP± 0,45), sendo a prevalência de DVA de 54,2%, com um total de 11,2% de valores abaixo de 0,35 μmol/L (Tabela 3). Idade materna (anos) < 20 20 a 35 > 35 Renda familiar per capita (salários mínimos) 5 Grau de escolaridade Analfabeta Ensino fundamental incompleto Ensino fundamental completo Ensino médio incompleto Ensino médio completo Superior
