The relationship between health-related quality of life (HRQoL), physical activity (PA), and cardiorespiratory fitness (CRF) among disadvantaged communities in low- and middle-income countries is poorly understood. In South Africa, children from socioeconomically deprived households are at an elevated risk of sedentary lifestyles and poor HRQoL. We examined whether higher self-reported PA and higher CRF levels are associated with better HRQoL in South African schoolchildren from disadvantaged neighbourhoods.
Overall, 832 children aged 8-12 years participated in this cross-sectional study. HRQoL was assessed through five dimensions of the KIDSCREEN-27 tool. Self-reported PA was measured using a single item of the Health-Behaviour of School-Aged Children test, and CRF with the 20-m shuttle run test.
Higher self-reported PA was significantly and positively related to HRQoL. Significant, but small group differences existed across all dimensions of HRQoL between low and high self-reported PA. No significant associations were observed between CRF levels and HRQoL.
Schoolchildren reporting PA of at least 60 min on at least 6 days a week (the recommended minimum) report higher HRQoL than their peers with lower PA levels.
在中低收入国家，健康相关生活质量（HRQoL）、体力活动（PA）和心肺功能适应性（CRF）之间的关系在处境不利社区中了解甚少。在南非，来自社会经济贫困家庭的儿童更有可能久坐不动和生活质量较差。我们研究了南非贫困社区的学童中，较高的自我报告体力活动水平和较高的 CRF 水平是否与更好的 HRQoL 相关。
共有 832 名 8-12 岁的儿童参与了这项横断面研究。通过 KIDSCREEN-27 工具的五个维度评估 HRQoL。使用 Health-Behaviour of School-Aged Children 测试的一个单项来衡量自我报告的 PA，使用 20 米往返跑测试来衡量 CRF。
较高的自我报告 PA 与 HRQoL 呈显著正相关。在所有 HRQoL 维度上，低和高自我报告 PA 之间存在显著的小组差异。CRF 水平与 HRQoL 之间没有显著的关联。
每周至少 6 天进行至少 60 分钟推荐最低运动量的儿童报告的 HRQoL 比低运动量的同龄人更高。
