Multidisciplinary obesity treatment program improved health-related quality of life and positively correlated with anthropometric and body composition but not with cardiorespiratory fitness parameters in adolescents.

Abstract

The aim of the present study was to verify the effects of a 16-week multidisciplinary obesity treatment program (MOTP) on health-related quality of life (HRQoL) in adolescents with weight excess. In addition, we verified a possible association between changes on HRQoL and anthropometric, body composition, and cardiorespiratory fitness (CRF) parameters. Two hundred four adolescents aged from 15 to 18years were distributed in control group (CG) and intervention group (IG). They underwent a 16-week MOTP composed by nutritional, psychological, and health-related physical activity group sessions. Moreover, they performed physical exercise sessions three times per week during the whole 16-week program. Data on HRQoL, body composition, CRF and anthropometry were collected using standard protocols and validated questionnaires. The MOTP promoted significant enhancements in all HRQoL domains, except for the school domain in IG. Furthermore, positive correlations between HRQoL and body weight (BW), body fat (BF), waist circumference (WC), and body mass index (BMI) z-score were verified. Higher scores of HRQoL might be achieved by improving these variables. The 16-week MOTP was effective to improve HRQoL in adolescents with weight excess. This improvement has a positive correlation with enhancements in BW, BMI z-score, WC, and BF. Nevertheless, these findings have not reached a consensus on literature and still need to be further enlightened.
