Reduced physical activity is a known risk factor for many illnesses. Research in adolescent populations found increased physical activity levels improves objective health outcomes, but there is conflicting evidence regarding the relationship between physical activity levels and self-reported health status. To synthesise current evidence on the association between physical activity and self-reported health status in adolescents. Secondary objectives are to assess whether the relationship is dose dependant, and the appropriateness of WHO recommendations on adolescents' physical activity. The main databases were searched using keywords for the main outcome of interest (health status, health behaviour and self-perception) and exposure of interest (motor activity, physical activity and exercise), supplemented with manual searches, secondary citation and reference searches. Quality appraisal was carried out using the Strengthening the Reporting of Observational Studies in Epidemiology checklist. Eleven studies entered this review. Nine studies reported a significant relationship between increased levels of physical activity and improved self-reported health status, however two did not. Two studies followed up participants and found that the relationship persisted over time. Two papers described a dose-response relationship. Improvements in self-perceived health can be observed even below the current recommended levels of physical activity. The review supports initiatives to encourage adolescents to engage in physical activity as it improves self-reported health status. Sub-optimal levels of physical activity can also be beneficial. Further research should use standardised measurement scales and objectively measured physical activity levels. The roles of gender, income and culture should be further investigated.
身体活动减少是许多疾病已知的风险因素。对青少年人群的研究发现，增加身体活动水平可改善客观健康结果，但关于身体活动水平与自我报告的健康状况之间的关系，证据存在矛盾。为综合当前关于青少年身体活动与自我报告的健康状况之间关联的证据。次要目标是评估这种关系是否存在剂量依赖性，以及世界卫生组织关于青少年身体活动建议的适当性。使用与主要关注结果（健康状况、健康行为和自我认知）和关注暴露因素（运动活动、身体活动和锻炼）相关的关键词搜索主要数据库，并辅以手动搜索、二次引用和参考文献搜索。使用《加强流行病学观察性研究报告规范》清单进行质量评估。11项研究纳入本综述。9项研究报告身体活动水平增加与自我报告的健康状况改善之间存在显著关系，然而有2项研究未发现此关系。2项研究对参与者进行了随访，发现这种关系随时间持续存在。2篇论文描述了剂量反应关系。即使低于当前推荐的身体活动水平，也可观察到自我感知健康状况的改善。该综述支持鼓励青少年参与身体活动的倡议，因为这可改善自我报告的健康状况。次优水平的身体活动也可能有益。未来研究应使用标准化测量量表，并客观测量身体活动水平。应进一步研究性别、收入和文化的作用。
