Meal consumption patterns and anthropometric measurements in adolescents from a low socioeconomic neighborhood in the metropolitan area of Rio de Janeiro, Brazil.

We investigated the association between meal consumption and anthropometric measurements in a probabilistic sample of 528 12-18-year-old adolescents assessed in a population-based cross-sectional study developed in the Rio de Janeiro Metropolitan Area, Brazil. A score ranging from zero to nine according to the frequency of meal consumption (breakfast, lunch and dinner) assessed meal patterns which were defined as satisfactory or unsatisfactory. Nutritional status was defined by the sex- and age-specific body mass index cut-offs. Underweight was observed in 5.7% of the adolescents (8.6% boys, 2.5% girls) and overweight in 20.9%. The omission of breakfast was observed in 4.5% of the boys and 12.4% of the girls. Unsatisfactory meal consumption pattern was more frequent among girls (38.7% vs. 29.2%), and among teenagers over 15 years of age (40.0% vs. 25.4%). Boys with unsatisfactory patterns of meal consumption presented higher means of BMI and of waist and hip circumferences than the ones with satisfactory patterns. The higher values of anthropometric measurement observed among adolescents with an unsatisfactory meal pattern indicate that they may be at risk for overweight or obesity.
