Life Satisfaction, Physical Activity and Quality of Life Associated with the Health of School-Age Adolescents

The main purpose of this study is to understand the Quality of Life Associated with Health (QLAH) of a sample of school-age adolescents, and the existing associations between the latter and other variables, such as family life satisfaction, personal life satisfaction (LS), friendships satisfaction, physical activity with family, friends and personal physical activity. The sample consisted of 1226 Spanish school-age adolescents (50.9% boys and 40.1% girls) with ages between 12 and 16 years old. Several scales that were extracted from the international Health Behaviour in School-aged Children (HBSC) 2016 study, sponsored by the World Health Organization (WHO), were used as working instruments in this piece of research. SPSS (24.0) was the software package used to perform the analyses of descriptive statistics, correlation and multiple regression, whereas AMOS (24.0) was used for structural equations. The results reveal a strong association between the physical activity (PA) students undertake (personal, with their families and friends) and life satisfaction, family life satisfaction and satisfaction with the relationships with friends. Additionally, both constructs (physical activity and satisfaction, understood as an indicator of good health) can predict the respondents’ Quality of Life Associated with Health. The variables (QLAH, LS and PA) are interrelated, thus resulting in major practical implications.
