Dieta e gordura corporal na adolescência.

Abstract

This study evaluated the longitudinal relationship between diet and body fat in adolescents. Dietary patterns were generated among the adolescents cohort of 1993 Pelotas at 15 and 18 years of age from dietary data obtained from food frequency questionnaire. Investigated the tracking and changes these patterns and their association with body fat. Body fat was assessed at 18 years of age through air displacement plethysmography (Bod Pod). Four dietary patterns were identified at 15 years of age (Varied, Traditional, Dieting and Processed Meats). Three of which were maintained at 18 years (Varied, Traditional and Diet) together with a fourth dietary pattern (Fish, fast food and alcohol). The dietary pattern more adhered to 15 years was the "Varied", while at 18 years was "Dieting". It was observed that adherence to any dietary pattern to 15 years was not directly associated with body fat percentage to 18. However, adolescents who adhered to a "Dieting" dietary pattern at 15 years and remained at 18, as well as those who changed to this dietary pattern from 15 to 18 years, had higher percentages of body fat.
