title: [Dietary patterns and its relation with overweight and obesity in Chilean girls of medium-high socioeconomic level].
abstract: The aim of the present study was to identify dietary patterns in girls and to assess their association with obesity or overweight. A school-based sample of 108 girls between 8 and 11 years of medium-high socioeconomic level was selected in Santiago, Chile. The body mass index was calculated and a quantified food frequency and physical activity questionnaires (validated in the FAO/MINEDUC/INTA Project Nutritional Education in primary schools) were applied. Four distinct dietary factors or patterns were obtained explaining 54% of the total variation using factorial analysis. The first factor was characterized by an energy-dense diet (high consumption of fat foods, ice creams, chocolates, French fries, snacks). The second factor represented a healthy diet (dairy products, fruits and salads). The third factor represented intake of soft drinks (either with or without sugar). The fourth factor represented a diet rich in calories and sugars (bread, sausages, sweets). The association between the four dietary factors and overweight/obesity was assessed through logistic regression models. The first factor, energy-dense foods, was the only one significantly associated with the presence of obesity (OR = 1.86; 95% CI: 1.12 - 3.09). The results of this research about dietary patterns are consistent with studies carried out in other countries.
