Health-related quality of life, Mediterranean diet, physical activity and socioeconomic factors of Greek adolescents during COVID-19: A cross sectional study

Abstract

BACKGROUND: Health related quality of life of the adolescents during quarantine and social isolation potentially decreases, with significant alteration on physical activities and nutrition behaviour. OBJECTIVE: The present study investigates the relationship between Greek adolescents’ health related quality of life and socioeconomic factors, lifestyle and dietary characteristics, along with their adherence to the Mediterranean Diet immediately after the lockdown period in Greece. METHODS: A total sample of 459 students aged 12–16 years old were recruited from secondary schools in the area of Athens. The KIDSCREEN-27 questionnaire for children and adolescents, the KIDMED test, the Godin and Shephard Leisure Time Physical Activity Questionnaire and the Family Affluence Scale III, were used for the statistical analysis. T-tests, Kruskal Wallis, Chi-square, Anova tests and multiple regression analyses were employed. RESULTS: Econometric analysis reveals that adolescents’ health related quality of life is higher among boys, adolescents who live with both parents, tend to sleep more during night and do not spend many hours on screen viewing. Also, adolescents with higher family affluence level, being physically active and with a high adherence to the Mediterranean Diet have higher health related quality of life. CONCLUSIONS: Adolescents’ adherence to the Mediterranean Diet, physical activity, socioeconomic characteristics and life style behaviors are highly correlated with perceived health related quality of life during COVID-19 period.
