To systematically review the effect of physical activity (PA) on health-related quality of life (HRQoL) among children and adolescents and the magnitude of association, so as to provide an evidence-based support for optimizing health promotion strategies for children and adolescents.
Medline (PubMed), EMBASE, the Cochrane Library, SCIELO, PEDro, CNKI, Wanfang and VIP databases were searched to collect literature on PA and HRQoL in children and adolescents, which were published up to January 1, 2025. Cochrane ROB tool and specific evaluation system were used to assess literature quality, Stata 16.0 software was used for Meta-analysis. For descriptive studies, correlation(r) and 95% confidence interval(CI) were used as effect indicators, and the inverse variance method was used to merge the data. Standardized mean difference(SMD) and 95%CI were used to calculate the combined effect size of intervention studies.
A total of 22 studies involving 27 303 healthy children and adolescents were included, including 9 descriptive studies and 13 intervention studies. The results of descriptive analysis showed that PA level was positively correlated with HRQoL (r=0.27, 95%CI=0.21-0.32, P < 0.01). The analysis of intervention studies showed that PA had significant effects on overall HRQoL (SMD=0.10, 95%CI=0.05-0.16), physical functioning (SMD=0.16, 95%CI=0.08-0.23), and mental functioning (SMD=0.17, 95%CI=0.10-0.25)(P < 0.01). Subgroup analysis found that the effects of physical activity on overall HRQoL, physiological function, and psychological function in children and adolescents were maximized when the intervention duration was less than 6 months (SMD=0.13, 0.18, 0.20), the frequency was≥5 times per week (SMD=0.13, 0.19, 0.24) and there was a supplementary plan(SMD=0.10, 0.18, 0.23)(P < 0.01).
PA is an important factor affecting the HRQoL of healthy children and adolescents, and the systematic PA intervention has a effect on improving the HRQoL.
