[Food consumption by pregnant adolescents in Rio de Janeiro, Brazil]

The increase in teenage pregnancy has been viewed with concern by public health experts. Food consumption to help maintain high nutrient demands has been identified as one of the most relevant components. This study aims to present the habitual consumption of food and energy-specific nutrients by pregnant adolescents. A total of 1,180 adolescent mothers were interviewed in maternity hospitals in the City of Rio de Janeiro, and a simplified questionnaire on semi-quantitative frequency of food consumption was applied. Lower consumption of fruit juice, vegetables, and fruits was observed among adolescent mothers over 15. Adolescent mothers classified in the lowest quartile of consumption lack the minimum recommended consumption of energy and nutrients. An inverse association was found between the number of household members and energy and nutrient consumption. Adolescent mothers who received dietary information and changed their eating habits during pregnancy showed better results concerning the consumption of energy and nutrients. Prenatal care was a key factor for improving the results of pregnancy, emphasizing the importance of providing dietary information.
