BACKGROUND
Physical activity is associated with health-related quality of life (HRQL) in clinical populations, but less is known whether this relationship exists in older men and women who are healthy. Thus, this study determined if physical activity was related to HRQL in apparently healthy, older subjects.
METHODS
Measures were obtained from 112 male and female volunteers (70 +/- 8 years, mean +/- SD) recruited from media advertisements and flyers around the Norman, Oklahoma area. Data was collected using a medical history questionnaire, HRQL from the Medical Outcomes Survey short form-36 questionnaire, and physical activity level from the Johnson Space Center physical activity scale. Subjects were separated into either a higher physically active group (n = 62) or a lower physically active group (n = 50) according to the physical activity scale.
RESULTS
The HRQL scores in all eight domains were significantly higher (p < 0.05) in the group reporting higher physical activity. Additionally, the more active group had fewer females (44% vs. 72%, p = 0.033), and lower prevalence of hypertension (39% vs. 60%, p = 0.041) than the low active group. After adjusting for gender and hypertension, the more active group had higher values in the following five HRQL domains: physical function (82 +/- 20 vs. 68 +/- 21, p = 0.029), role-physical (83 +/- 34 vs. 61 +/- 36, p = 0.022), bodily pain (83 +/- 22 vs. 66 +/- 23, p = 0.001), vitality (74 +/- 15 vs. 59 +/- 16, p = 0.001), and social functioning (92 +/- 18 vs. 83 +/- 19, p = 0.040). General health, role-emotional, and mental health were not significantly different (p > 0.05) between the two groups.
CONCLUSION
Healthy older adults who regularly participated in physical activity of at least moderate intensity for more than one hour per week had higher HRQL measures in both physical and mental domains than those who were less physically active. Therefore, incorporating more physical activity into the lifestyles of sedentary or slightly active older individuals may improve their HRQL.
背景
在临床人群中，身体活动与健康相关生活质量（HRQL）相关，但对于健康的老年男性和女性中是否存在这种关系，人们了解较少。因此，本研究确定了在明显健康的老年受试者中，身体活动是否与HRQL相关。
方法
从俄克拉荷马州诺曼地区周围通过媒体广告和传单招募的112名男性和女性志愿者（70±8岁，均值±标准差）获取测量数据。使用病史问卷、医学结果调查简表-36问卷中的HRQL以及约翰逊航天中心身体活动量表来收集身体活动水平数据。根据身体活动量表，将受试者分为身体活动水平较高组（n = 62）或身体活动水平较低组（n = 50）。
结果
报告身体活动水平较高的组在所有八个领域的HRQL得分均显著更高（p < 0.05）。此外，与身体活动水平较低组相比，身体活动水平较高组的女性较少（44% 对 72%，p = 0.033），高血压患病率较低（39% 对 60%，p = 0.041）。在对性别和高血压进行调整后，身体活动水平较高组在以下五个HRQL领域的值更高：身体功能（82±20对68±21，p = 0.029）、角色-身体（83±34对61±36，p = 0.022）、身体疼痛（83±22对66±23，p = 0.001）、活力（74±15对59±16，p = 0.001）和社会功能（92±18对83±19，p = 0.040）。两组之间的总体健康、角色-情感和心理健康没有显著差异（p > 0.05）。
结论
每周定期进行至少中等强度身体活动超过一小时的健康老年人，在身体和心理领域的HRQL测量值均高于身体活动较少的老年人。因此，将更多的身体活动纳入久坐或轻度活动的老年人的生活方式中，可能会改善他们的HRQL。
