Regular physical activity is associated with multiple health benefits for children. Evidence from cross-sectional studies suggests that physical activity is positively associated with health-related quality of life (HRQoL). The promotion of physical activity, and hence HRQoL, through a school-based intervention is therefore an important endeavor, particularly in disadvantaged areas of low- and middle-income countries, including South Africa.
We designed a multicomponent physical activity intervention that was implemented over a 20-week period in 2015 in eight disadvantaged primary schools of Port Elizabeth, South Africa. Overall, 687 children aged 8-13 years participated. HRQoL was measured with the 27-item KIDSCREEN questionnaire. Self-reported physical activity was assessed with a single item of the Health-Behavior of School-Aged Children test, and cardiorespiratory fitness with the 20-m shuttle run test.
Higher baseline levels as well as increasing levels of self-reported physical activity predicted children’s HRQoL. Baseline levels and increases in cardiorespiratory fitness predicted children’s self-perceived physical wellbeing (a HRQoL subscale). Participation in the multicomponent physical activity intervention only explained limited variance in children’s HRQoL.
Higher and increasing self-reported physical activity predict HRQoL, which underlines that the promotion of regular physical activity among children living in disadvantaged settings is an important public health measure. Policy makers should encourage schools to create physical activity friendly environments while schools should implement regular physical education as proposed by the school curriculum.
