Although the benefits of regular physical activity on morbidity and mortality are established, relationships between recommended levels of physical activity and health-related quality of life (HRQOL) have not been described. The authors examined whether recommended levels of physical activity were associated with better HRQOL and perceived health status.
Using data from 175,850 adults who participated in the 2001 Behavioral Risk Factor Surveillance System survey, the authors examined the independent relationship between recommended levels of moderate or vigorous physical activity and four measures of HRQOL developed by the U.S. Centers for Disease Control and Prevention. Multivariate logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for age, race/ethnicity, sex, education, smoking status, and body mass index.
The proportion of adults reporting 14 or more unhealthy days (physical or mental) was significantly lower among those who attained recommended levels of physical activity than physically inactive adults for all age, racial/ethnic, and sex groups. After multivariate adjustment, the relative odds of 14 or more unhealthy days (physical or mental) in those with the recommended level of activity compared to physically inactive adults was 0.67 (95% CI: 0.60, 0.74) for adults aged 18-44 years, 0.40 (95% CI: 0.36, 0.45) for adults aged 45-64 years, and 0.41 (95% CI: 0.36, 0.46) for adults aged 65 years or older. The results persist even among adults with a chronic condition such as arthritis.
These results highlight the need for health programs to increase participation in regular physical activity.
尽管规律体育活动对发病率和死亡率的益处已得到证实，但推荐的体育活动水平与健康相关生活质量（HRQOL）之间的关系尚未得到描述。作者研究了推荐的体育活动水平是否与更好的HRQOL和感知健康状况相关。
利用参加2001年行为危险因素监测系统调查的175,850名成年人的数据，作者研究了推荐的中等或剧烈体育活动水平与美国疾病控制与预防中心制定的四项HRQOL指标之间的独立关系。采用多变量逻辑回归来获得调整年龄、种族/民族、性别、教育程度、吸烟状况和体重指数后的比值比（OR）和95%置信区间（CI）。
在所有年龄、种族/民族和性别组中，达到推荐体育活动水平的成年人报告14天或更多不健康天数（身体或精神方面）的比例显著低于不参加体育活动的成年人。多变量调整后，与不参加体育活动的成年人相比，达到推荐活动水平的成年人出现14天或更多不健康天数（身体或精神方面）的相对比值比在18 - 44岁成年人中为0.67（95%CI：0.60, 0.74），在45 - 64岁成年人中为0.40（95%CI：0.36, 0.45），在65岁及以上成年人中为0.41（95%CI：0.36, 0.46）。即使在患有关节炎等慢性病的成年人中，结果依然成立。
这些结果凸显了健康项目增加规律体育活动参与度的必要性。
