Body Dissatisfaction, Weight Status and Health-related Quality of Life in Adolescents

Abstract

Background: Studies on the effect of weight on quality of life provide conflicting results. The purpose of the research was to assess the interconnection between the anthropometric variables and health-related quality of life (HRQoL) in a community-based sample of schoolchildren and to establish the role of body dissatisfaction (BD) in this association. Methods: A number of tenth-year schoolchildren ( n = 413) completed a questionnaire making it possible to describe their sociodemographic and behavioral characteristics and assess body satisfaction and HRQoL (PedsQL 4.0, France). The hypothesis of BD as reflecting the relationship between anthropometric variables and HRQoL was tested using the logistic regression method. Results: No significant correlation was found between BMI and integral HRQoL scores. Waist circumference showed a significant negative correlation with the HRQoL scores in the girls, but not in the boys. The frequency of BD was 60.3% ( n = 249). The relationship between BD and anthropometric variables proved to be differently directed in the boys and the girls. BD had a significant negative correlation with psychosocial and total HRQoL scores in adolescents of both sexes and with the girls’ physical functioning scores. The relationship between HRQoL and anthropometric indices in the girls, after making adjustment for sociodemographic, behavioral variables and BD in multivariate models, was no longer significant. Conclusion: This study has shown that BD is widespread among adolescents and has a significant impact on HRQoL. The impact of actual weight status on girls’ quality of life is entirely mediated by their dissatisfaction with their own bodies, thus justifying the approach to BD as a stand-alone problem having important psychosocial implications and requiring active identification and targeted intervention.
