title: Dietary patterns of Brazilian adolescents: results of the Brazilian National School-Based Health Survey (PeNSE).
abstract: The objectives of this study were to identify dietary patterns in Brazilian adolescents, describe their distributions in Brazil's State capitals and Federal District, and analyze the correlations with the Municipal Human Development Index (HDI-M). The study analyzed a sample of 60,954 ninth-graders from public and private schools who participated in the National School-Based Health Survey (PeNSE) in 2009. Cluster analysis was used to characterize dietary patterns. Three patterns were identified: healthy (27.7%), unhealthy (34.6%), and mixed (37.7%). Adolescents in the country's Southeast, South, and Central West regions showed a higher proportion of the healthy eating pattern. HDI-M showed a positive correlation with the healthy pattern and a negative correlation with the mixed pattern. The identification of different dietary patterns within and between regions and according to HDI-M highlights the need for better knowledge of each local context in terms of both the magnitude of events and the examination of determinants within these different realities.
