Subjective and social well-being, avoiding sedentary behavior (SB), and engaging in physical activity (PA) are important factors for health in older adults, but the extent to which they are related to each other remains unclear. We aimed to investigate these correlations, and whether they differ by age.
A cross-sectional study was carried out in 595 people aged 66 years and older, from the Swedish National study on Aging and Care in Kungsholmen. Subjective and social well-being (life satisfaction, positive and negative affect, social connections, social support, and social participation) were assessed through validated questionnaires and activPAL3 accelerometers provided information on SB and PA. Data were analyzed using multi-adjusted quantile regression models.
Higher positive affect was significantly associated with less daily sitting time (β = -27.08, 95% confidence interval [CI]: -47.77, -6.39) and higher levels of light PA (LPA) (β = 40.67, 95% CI: 21.06, 60.28). Higher levels of social support and social participation were associated with less daily sitting time (β = -22.79, 95% CI: -39.97, -5.62; and β = -21.22, 95% CI: -39.99, -2.44) and more time in LPA (β = 23.86, 95% CI: 4.91, 42.81; and β = 25.37, 95% CI: 6.27, 44.47). Stratified analyses suggested that the associations of positive affect and social participation were strongest for individuals aged 80 years and older.
Our results suggest that older adults with higher levels of subjective and social well-being spend less time sitting and engage more in PA. This was especially evident among the oldest-old individuals. Future research should longitudinally investigate the directionality of these correlations.
主观和社会幸福感、避免久坐行为（SB）和进行身体活动（PA）是老年人健康的重要因素，但它们之间的关联程度尚不清楚。我们旨在研究这些相关性，以及它们是否因年龄而异。
这项横断面研究在瑞典 Kungsholmen 老龄化和护理国家研究中招募了 595 名年龄在 66 岁及以上的参与者。通过验证过的问卷和 activPAL3 加速度计评估主观和社会幸福感（生活满意度、积极和消极情绪、社交联系、社会支持和社会参与），后者提供了关于 SB 和 PA 的信息。使用多调整分位数回归模型分析数据。
更高的积极情绪与每天坐着的时间减少（β = -27.08，95%置信区间 [CI]：-47.77，-6.39）和更高水平的低强度 PA（LPA）（β = 40.67，95% CI：21.06，60.28）显著相关。更高水平的社会支持和社会参与与每天坐着的时间减少（β = -22.79，95% CI：-39.97，-5.62；和β = -21.22，95% CI：-39.99，-2.44）和更多的 LPA 时间相关（β = 23.86，95% CI：4.91，42.81；和β = 25.37，95% CI：6.27，44.47）。分层分析表明，积极情绪和社会参与与 80 岁及以上人群的相关性最强。
我们的结果表明，主观和社会幸福感水平较高的老年人坐的时间更少，参与身体活动的时间更多。这在最年长的老年人中尤为明显。未来的研究应该纵向调查这些相关性的方向性。
