Associação entre o nível de atividade física, sobrepeso e obesidade em adolescentes entre 14 e 16 anos de um estabelecimento particular de ensino da cidade de Curitiba

Abstract

The objective of this study was to investigate the association between the level of physical activity, overweight and obesity in adolescents between 14 and 16 years of age of a particular educational establishment in the city of Curitiba. Participants 316 adolescents (161 males and 155 females) selected by invitation and willingness of all the students enrolled in first. and 2nd. series of high school. The level of physical activity was assessed by two questions where teenagers should report the number of days per week in performing physical activities for more than 20 and more than 60 minutes according to the recommendations (Cavill; BIDLLE ; Salles, 2001). To assess overweight and obesity used BMI as the index. For the classification of overweight and obesity, we used the criteria proposed by Miller et al. (2010). The data were processed by descriptive statistics to characterize the sample and to test the association between overweight and obesity with physical activity we used the chi-square test for proportions adopting a 5% significance level. It was observed that only 32.2% of adolescents surveyed reach the criterion of physical activity 20 minutes a day. As the proportion of those who reach the criterion of 60 minutes is 21.6%. This means that 67.8 and 78.4% respectively have insufficient levels of physical activity for health maintenance. 25.9% are overweight and obesity 2.5%. However, when comparing the proportion of adolescents who are overweight and obesity with physical activity level did not detect a significant difference between those who meet the criteria of 20 and 60 minutes daily. Although there was no significant association, the levels of overweight and obesity with physical activity, overweight levels are high which suggests some kind of counseling / intervention, because the behavior during adolescence tend to be maintained during adulthood.
