背景:生活满意度(LS)是积极心理感觉的一部分,可以保护个人免受老年时身体下降的影响。健康的生活方式,包括体力活动(PA)和健康饮食,例如水果和蔬菜的摄入量(F&V),可以在老年人中获得更好的LS体验。然而,对于LS,在老年人中同时发生PA和F&V摄入习惯之间的关联尚不清楚.该研究旨在调查台湾老年人群的LS中PA和F&V摄入量的综合关联。
方法:分析了1999年至2015年台湾老龄化纵向调查收集的五波基于人口的数据。1999年被定为基线,受访者人数为4,440人。独立变量包括频率,持续时间,PA的强度和F&V摄入的频率。LS采用生活满意度指数进行评估。我们进行了广义估计方程(GEE)分析,并对健康行为和健康指标的协变量进行了调整。
结果:调整混杂因素后,模型1显示,中度和高度PA水平与LS(比值比[OR]=1.41,95%CI=1.12-1.79)和OR=1.74,95%CI=1.50-2.02)显着相关。此外,高F&V摄入量与LS显著相关(OR=2.07,95%CI=1.69-2.53)。关于模型2中显示的组合关联,与低PA和F&V摄入量组相比,双高组的LS显著较高(OR=4.69,95%CI=3.49-6.31),仅高F&V摄入量(OR=2.87,95%CI=2.14-3.85),仅高PA(OR=2.48,95%CI=1.74-3.52)。
结论:我们的研究结果表明,老年人中PA和F&V摄入量与LS之间存在显著的联合关联。此外,从事频率较高的老年人,持续时间,每日PA的强度加起来每周7次以上的F&V摄入量的LS明显高于仅从事低PA或仅摄入较少F&V的人群。在日常生活中采用多种健康行为是在老年人中促进LS的安全有效方法。
Life satisfaction (LS) is part of a positive psychological feeling that protects individuals from a physical decline in old age. A healthy lifestyle, including physical activity (PA) and a healthy diet, such as the intake of fruits and vegetables (F&V), can lead to a better experience of LS in older adults. However, the association between PA and F&V intake habits when occurring together in older adults is still unclear for LS. The study aimed to investigate the combined association of PA and F&V intake on LS among a cohort of older Taiwanese adults.
Five waves of population-based data gathered by the Taiwan Longitudinal Survey on Aging between 1999 and 2015 were analyzed. The year 1999 was set as the baseline, and the number of respondents was 4,440. The independent variables included the frequency, duration, and intensity of PA and the frequency of F&V intake. LS was assessed by using the Life Satisfaction Index. We performed generalized estimating equations (GEE) analysis with adjustment for covariates of health behaviors and health indicators.
After adjusting for confounders, model 1 showed that moderate and high-PA levels significantly correlated with LS (odds ratio [OR] = 1.41, 95% CI = 1.12-1.79) and OR = 1.74, 95% CI = 1.50-2.02). Moreover, high-F&V intake significantly correlated with LS (OR = 2.07, 95% CI = 1.69-2.53). Regarding the combined association shown in model 2, compared with both the low PA and F&V intake group, there were significantly higher LS in the both-high-group (OR = 4.69, 95% CI = 3.49-6.31), only-high-F&V intake (OR = 2.87, 95% CI = 2.14-3.85), only-high-PA (OR = 2.48, 95% CI = 1.74-3.52).
Our findings show the significant combined association of PA and F&V intake on LS among older adults. In addition, older adults who engaged in higher frequency, duration, and intensity of daily PA combined more than seven times a week of F&V intake had significantly higher LS than those who only engaged in low PA or only intake less F&V. Adopting multiple healthy behaviors in daily life is a safe and effective approach to promote LS among older adults.
