目的：探讨健康相关生活质量(HRQOL)与体力活动(PA)的关系。方法：通过全国电话调查获得9173名调查对象的横断面数据(应答率30.9%，协作率51.4%)。测量HRQOL的4项指标：自评健康、身体不健康天数、精神不健康天数和活动受限天数。根据体重指数(BMI)类别和PA水平计算患病率估计值。Logistic回归分析将体重指数作为高质量生活质量与个人生活质量之间关系的效应修饰符。结果：无论体重指数类别如何，不活跃的成年人对较差的高质量生活质量的评价均高于活跃的成年人(P<；0.001)。结论：低HRQOL的患病率与PA的参与程度呈负相关，且这种关系不受BMI状态的影响。不管成年人的体重状况如何，都应该鼓励他们参与PA。
Objective: To examine the association between health-related quality of life (HRQOL) and physical activity (PA).Methods: Cross-sectional data were obtained via a national telephone survey from 9173 respondents (30.9% response rate; 51.4% cooperation rate). Four indicators of HRQOL were measured: self-rated health, physically unhealthy days, mentally unhealthy days and activity limitation days. Prevalence estimates were calculated by body mass index (BMI) category and PA level. Logistic regression evaluated BMI as an effect modifier of the relationship between HRQOL and PA.Results: Inactive adults reported more fair to poor HRQOL than active adults, regardless of BMI category (P < 0.001). BMI did not modify the association between PA and any of the four HRQOL indicators.Conclusion: Prevalence of low HRQOL is inversely related to PA participation, and the relationship is not altered by BMI status. Regardless of their weight status, adults should be encouraged to engage in PA.
