尽管体力活动与生活质量 (QOL) 相关，但有关这种关系背后机制的经验证据有限。在本研究中，我们以社区居住的老年人为样本，研究了自我效能感和健康状况在从基线到 18 个月随访的身体活动与生活质量关系中所发挥的中介作用。社区居住的成年人（N = 321，M 年龄 = 63.8 岁）被招募参加一项横断面研究，随后联系参加 18 个月的随访。个人完成了一系列问卷调查，评估身体活动、自我效能、身体自我价值、残疾限制和生活质量。使用协方差建模框架内的面板分析来分析数据。总体而言，该模型与数据拟合良好（χ2 = 61.00，df = 29，p < 0.001，标准化根均值残差 = 0.05，比较拟合指数 = 0.97），身体活动的变化通过独立于基线关系和人口因素的运动自我效能、身体自我价值和残疾限制的变化，间接影响从基线到 18 个月的生活满意度变化。具体来说，体力活动的增加与运动自我效能的提高相关，而运动自我效能感又与更高的身体自我价值和更少的残疾限制相关，而残疾限制则与更高的生活满意度相关。这项研究的结果表明，老年人身体活动与整体生活质量之间的关系可能是通过更近端的可改变的结果来调节的，这些结果可以作为身体活动计划和干预措施的目标。
Although physical activity has been associated with quality of life (QOL), the empirical evidence regarding the mechanisms underlying this relationship is limited. In the present study, we examined the mediating roles played by self-efficacy and health status in the physical activity-QOL relationship from baseline to 18-month follow-up in a sample of community dwelling older adults. Community dwelling adults (N = 321, M age = 63.8 years) were recruited to participate in a cross-sectional study and were later contacted to participate in an 18 month follow-up. Individuals completed a battery of questionnaires assessing physical activity, self-efficacy, physical self-worth, disability limitations, and quality of life. A panel analysis within a covariance modeling framework was used to analyze the data. Overall the model was a good fit to the data (χ2 = 61.00, df = 29, p < 0.001, Standardized Root Mean Residual = 0.05, Comparative Fit Index = 0.97) with changes in physical activity indirectly influencing change in life satisfaction from baseline to 18 months via changes in exercise self-efficacy, physical self-worth, and disability limitations independent of baseline relationships and demographic factors. Specifically, increases in physical activity were associated with increases in exercise self-efficacy which, in turn, was associated with higher physical self-worth and fewer disability limitations which were associated with greater life satisfaction. The findings from this study suggest the relationship between physical activity and global QOL in older adults may be mediated by more proximal modifiable outcomes that can be targeted in physical activity programs and interventions.
