Physical capacity and subjective wellbeing are important for healthy aging. Our aim was to study how objective/subjective physical capacity and subjective health relate to life satisfaction, in a 10-year follow-up of aging women.
The participants (n = 1485, mean age 67.4 years) consisted of community-dwelling older women living in Kuopio, Finland. Grip strength and one-legged stance test time were used as objective, and self-rated mobility (SRM) as subjective physical capacity measures. Self-rated health (SRH) and SRM were assessed with one-item scales and life satisfaction with a 4-item scale. Correlation and linear regression were used to analyze these relationships and correlation network analysis to visualize them. Age and BMI were included in the analysis as adjusting factors.
All the study variables were significantly correlated with baseline and follow-up life satisfaction, except BMI, which was only associated with life satisfaction at follow-up. On both occasions, SRH and SRM were the two strongest correlates of life satisfaction, but their mutual correlation was still higher. In linear regression analyses, SRH was positively associated with both baseline and follow-up life satisfaction, but physical capacity measures became non-significant after including SRH and SRM in the model. In the partial correlation network analyses, SRH and SRM were the most central nodes, connecting every other variable.
Self-reports on health, mobility, and life satisfaction are closely intertwined and provide easily accessible health information among aging women, but the impacts of objective physical capacity measures warrant further longitudinal studies in respect to subjective wellbeing among aging people.
身体能力和主观幸福感对健康老龄化很重要。我们的目的是研究在对老年女性进行的 10 年随访中，客观/主观身体能力和主观健康与生活满意度的关系。
参与者（n=1485，平均年龄 67.4 岁）由居住在芬兰库奥皮奥的社区老年人组成。握力和单腿站立测试时间用作客观指标，自我评估的移动能力（SRM）用作主观身体能力指标。自我评估的健康（SRH）和 SRM 使用单项量表进行评估，生活满意度使用 4 项量表进行评估。使用相关和线性回归分析这些关系，并使用相关网络分析可视化它们。年龄和 BMI 被纳入分析作为调整因素。
除 BMI 外，所有研究变量均与基线和随访生活满意度显著相关，而 BMI 仅与随访时的生活满意度相关。在这两种情况下，SRH 和 SRM 是生活满意度的两个最强相关因素，但它们之间的相互相关性仍然更高。在线性回归分析中，SRH 与基线和随访生活满意度均呈正相关，但在包括 SRH 和 SRM 后，身体能力测量变得不显著。在部分相关网络分析中，SRH 和 SRM 是最中心的节点，连接着其他每个变量。
健康、移动能力和生活满意度的自我报告紧密交织在一起，为老年女性提供了容易获得的健康信息，但客观身体能力测量对老年人主观幸福感的影响还需要进一步的纵向研究。
