Abstract
Objective: To evaluate spirometric indices and quality of life of children and adolescents with obesity and their correlation with body mass index (BMI). Methods: Observational, cross-sectional, quantitative study, comprising 48 volunteers of both sexes, aged 8 to 12 years, divided into Group 1 (G1; eutrophic) and Group 2 (G2; obese). Anthropometric, spirometric data and the response to the Pediatric Quality of Life Iventory (PedsQL™) child report and Pediatric Quality of Life Iventory (PedsQL™) parents report for child questionnaires were collected. Descriptive and inferential statistical data were analyzed with the aid of the BioEstat software version 5.3, considering p £ 0.05. Results: The sample, with a mean age of 10.42 (±1.28) years, being 60.41% male, did not show statistical significance for the domains of the QOL questionnaire between G1 and G2, as well as for the spirometric profile. However, a significant difference was observed for scores in four domains regarding the perception of parents and their children for PedsQL4.0. Conclusion: There was no direct correlation between BMI, spirometric data and the quality of life of the studied volunteers.
