Prevalência de sobrepeso/obesidade e fatores associados, em escolares de 10 a 14 anos de Campo Grande - MS

Abstract

Important changes in the lifestyle contributing for the development of obesity and overweight on children, mainly through the sedentariness and bad eating habits. The aim of this study was to assess the prevalence of overweight and obesity in schoolchildren with 10 to 14 years old from Campo Grande - MS, and to identify some factors associated to the alimentary and physical activity habits. The sample was composed of 941 students (50.3% male), being 758 students from public school and 183 from private school. For assessment of anthropometric data was used body mass index, and the standard adopted for the classification was Cole et. al. (2000) reference for children and adolescents. The body composition was obtained through the percentage body fat, estimated from the value of triceps to scapular skinfold thickness, where were used the predictive equations compiled by Slaughter et. al. and the classification was held though the proposed by Lohman (1987), specifies for children and adolescents between 7 to 14 years old. The habits of physical activity and feed were obtained through an easy acceptance. The results showed prevalence ration of 23.1% overweight and obesity on students and 56.1% presented high body fat. Overweight and obesity prevalence was higher in the schoolchildren with signs of present sexual maturation; and the scholars' frequency with weight excess was lower with those of the larger old year. Overweight and obesity prevalence was higher in the schoolchildren with signs of present sexual maturation; and the scholars' frequency with weight excess was smaller with those of the larger old year. There was not association between obesity or overweight prevalence and the of physical activity and the alimentary habits, except the weekly time destined to the physical education practice wich was higher for the scholars of low or appropriate body fat percentage. The students of the private schools presented a prevalence 1.5 times higher of overweight and obesity, and 1.3 times higher of high body fat percentage, indicating that is necessary further analysis in this population, as well as the adoption of measures to minimize the obesity in childhood and adolescence as to stimulate the change of habits, since that problem may persist in the adult life, providing even more worrying problems.
