Abstract

Introduction: The etiology of overweight and obesity in children and adolescents, as well as its relationship with physical activity, fitness and caloric intake underlie greater investigative interest. Objectives: examine the associations between dietary composition, physical activity levels and physical fitness in children and adolescents with overweight and obesity in Matola city. Methods: 106 subjects of both sexes aged 10 to 15 years old (61 girls and 45 boys) were selected for convenience. Anthropometric measurements consisted of weight, height and waist circumference, measured according to the procedures described by Lohman et al.1 The body mass index resulted from the weight ratio by the square of height. The battery of motor test Fitnessgram2 was used to assess physical fitness. The modified and adapted by Florindo et al.3 for children and adolescents of the Baecke4 questionnaire was administered to assess physical activity. The feed composition was determined from information obtained through the questionnaire on eating habits. To examine the association between the variables of interest was applied to the Chi-Square in SPSS 21.0 program, 95% confidence interval. Results: There were obvious higher proportions of subjects classified as unfit in almost all tests of physical fitness, especially aerobic capacity, where the proportions, differ significantly (apt: 2 (1.9%); unfit: 104 (98.1%), X2 = 13.396; p<0.01). The physical activity of vigorous intensity proved to be associated with all indicators of physical fitness. The food composition did not limit the results observed in physical fitness. Conclusions: confirmed the negative influence of both overweight, as obesity on physical fitness; the association between physical fitness and physical activity seemed to be determined by the intensity of this; the feed composition was not consistently associated with any variable.
