Finally, the “Traditional” pattern corresponded to 5.24% of the variability, indicating a high consumption of rice, tuberous roots, beans, red and white meat, eggs, processed meats, and artificial juices. Table 2 shows the results of the bivariate and multivariate regression analysis of factors associated with dietary patterns. The bivariate regression analysis indicated that adolescents
with per capita family income higher than half a minimum wage were more likely to consume foods of the “junk food” pattern (OR = 1.66, 95% CI = 1.07 to 2.56), whereas overweight adolescents were less likely to consume food of the “healthy” pattern (OR = 0.56, 95% CI = 0.35 to 0.91). After adjusting the data to the logistic regression model, these variables still remained significant (p < 0.05), with explanatory power similar Fulvestrant mw to that of previous analysis. This study identified, by applying the principal component analysis (PCA), three dietary patterns among check details the adolescents: “junk food,” “healthy,” and “traditional.” It also showed that the consumption of low nutritional quality foods was positively associated with family income, and that overweight adolescents usually do not consume foods from the “healthy” pattern. Dietary patterns can vary depending on cultural, geographic, and economic habits. Thus, although different studies consider
a dietary pattern with the same name, e.g., “Western diet”,4 and 20 it does not mean that the food items this pattern represents in each context are the same. In the present study, the terminology used for the dietary patterns was based on Brazilian studies. The study by Salvatti et al.7 identified, in adolescents from a public school in the city of São Paulo, the “traditional,” “urban,” “healthy,” and “junk food” patterns.7 In another study based on obese adolescents, Dishchekenian et al.21 classified Protein Tyrosine Kinase inhibitor the patterns as “traditional,” “in transition,” and “fast food.” It should be emphasized, however, that the type of foods grouped in each category is specific for each study. The “traditional” dietary
pattern corresponded to foods found in the staple diet of Brazilians, and is similar to the “traditional” pattern reported in other studies.7, 17 and 21 In the present study, this pattern included the consumption of processed meats and artificial juices, which may indicate a trend toward the inclusion of new items in the staple diet of the Brazilian population. The Household Budget Survey (HBS) conducted in 2008-200922 confirms the increased consumption of these, often due to their convenience and low cost. The foods that constitute the “healthy” dietary pattern are rich in vitamins, minerals, and fiber, which are considered protective against nontransmissible chronic diseases.23 This dietary pattern also includes skim dairy products, which have a low percentage of fat. The low consumption of these foods by adolescents has piqued the interest of researchers.
