Anthropometric indices as predictor of obesity and comorbidities in children from public schools in Southern Brazil
Main Article Content
Abstract
Introdução: To analyse anthropometric indices as predictors of obesity and its comorbidities among children in public schools in an urban area of southern Brazil. Methods: Cross-sectional study with a sample of 283 students aged 7-8 years, from public schools in southern Brazil. Weight (W), height (H), abdominal waist (AW) and body mass index (BMI) were obtained, according to the Technical Standard of the Ministry of Health; the abdominal waist to height ratio was also
evaluated (W / H). For the statistical analysis between the variables, the Pearson correlation index was used. Results: The students are on average 7.8 years old, 164 (58%) of whom are male; in relation to AW, it was found that in 27 (9.54%) students it is high, of which 15 (55.55%) are girls. As for W / H, 89 (31.50%) of the students have this high index, 59 (66.29%) of which are girls.Conclusions: There is a high
proportion of severe obesity, 3.7 times higher in boys. The values of high AW were similar between boys (15) and girls (12), however the high W / H was higher in girls (66.29%). Although boys have severe obesity, girls also appear to be at cardiovascular risk due to higher W / H. There was also a statistically linear and highly significant correlation between W / H and AW, with p <0.001. The study suggests that AW is equally important in detecting obesity and possibly central
