Prevalência e concordância na predição de excesso de peso corporal por dois critérios antropométricos em adolescentes da Amazônia ocidental brasileira

Abstract

-The aim of this study was to identify the prevalence and concordance of excess weight (BMI) and body fat (fat %) in adolescents of both sexes from cities of Rio Branco-AC and Porto Velho-RO. This study evaluated 4,310 adolescents, 2,167 from Rio Branco and 2,143 from Porto Velho. No difference (p=0.46) for excess weight between adolescents from Rio Branco (34.8%) and Porto Velho (33.8%) was observed. Fat percentage was significantly higher (p<0.01) in adolescents from Porto Velho (59.8%) compared to those from Rio Branco (44.3%). In intra-pubertal and pubertal stages, moderate concordance was identified (p<0.01) and in pre-pubertal stage, substantial concordance was observed (p<0.01). Thus, the findings of this study point out the adequacy of screening and diagnosis of obesity and overweight, which will enable earlier approach and treatment of adolescents.Key words: Adolescents; Body fat; Body mass index; Overweight.

Overweight and obesity: prevalence in children and adolescents in Northern Brazil

“…In addition, because the evaluation used only the zBMI that measures overall value of fat and lean mass and may present false positives. It should be noted the recommendation made by Farias et al 28 that the two indicators, zBMI and fat percentage are identification tools of overweight and obesity in order to avoid false positives.…”
