摘要：OBJETIVO: Descrever a prevalência de deficiência de vitamina A (DVA) em gestantes adolescentes segundo os indicadores: funcional (cegueira noturna - XN gestacional) e dietético (consumo dietético inadequado de vitamina A), bem como os fatores associados à XN gestacional. MÉTODOS: Estudo transversal desenvolvido com 303 gestantes adolescentes (idade RESULTADOS: A prevalência de XN gestacional foi de 13.2% (n=40). O fator associado com a XN gestacional nas adolescentes identificado no modelo final da regressão logística foi o uso de cigarro e álcool na gestação (OR = 3.94; IC 95% 1.01-15.41). Embora não associado à XN gestacional, o consumo inadequado de vitamina A foi observado em 44,1% e 38,1% das adolescentes, no 1º. e 2º. trimestres de gestação, respectivamente. CONCLUSÃO: Os achados revelam alta prevalência de XN gestacional e de consumo dietético inadequado de vitamina A dentre as gestantes adolescentes. A investigação da XN gestacional deve fazer parte das rotinas de pré-natal.
其他摘要：OBJECTIVE: Describe the prevalence of vitamin A deficiency (VAD) in pregnant adolescent women according to the indicators: functional (gestational night blindness -XN) and dietary (inadequate dietary intake of vitamin A), as well as factors associated with gestational XN. METHODS: Cross-sectional study developed with 303 pregnant teenage mothers (age<20 years), with a single fetus gestation and without chronic diseases, attended at a public maternity hospital in Rio de Janeiro. 76 women were attended in the period 2004-2006, called group I, and 227 attended in the period 2007-2010, called group II. XN was identified through a validated interview. The dietary intake of vitamin A was evaluated by the semi-quantitative consumption frequency method. Multivariate logistic regression was used to identify the factors associated with gestational XN. RESULTS: The prevalence of gestational XN was 13.2% (n = 40). Factor associated with gestational XN in pregnant adolescents was the use of cigarettes and alcohol during pregnancy (OR = 3.94, 95% CI 1.01-15.41). Although was not associated with gestational XN, inadequate intake of vitamin A was observed in 44.1% and 38.1% of adolescents, in the 1st. and 2nd. trimesters, respectively. CONCLUSION: The findings describe a high prevalence of gestational XN and inadequate dietary intake among pregnant adolescents. The investigation of gestational XN should be part of prenatal routines.
