Our aim was to examine whether engagement in productive activities, including volunteering, paid work, and childcare, protects older adults against the development of geriatric frailty.
Data from the first (1988) and second (1991) waves of the MacArthur Study of Successful Aging, a prospective cohort study of high-functioning older adults aged 70-79 years (n = 1,072), was used to examine the hypothesis that engagement in productive activities is associated with lower levels of frailty 3 years later.
Engagement in productive activities at baseline was associated with a lower cumulative odds of frailty 3 years later in unadjusted models (odds ratio [OR] = 0.74, 95% confidence interval [CI] = 0.58-0.96) but not after adjusting for age, disability, and cognitive function (adjusted OR = 0.78, 95% CI = 0.60-1.01). Examination of productive activity domains showed that volunteering (but neither paid work nor childcare) was associated with a lower cumulative odds of frailty after adjusting for age, disability, and cognitive function. This relationship diminished and was no longer statistically significant after adjusting for personal mastery and religious service attendance.
Though high-functioning older adults who participate in productive activities are less likely to become frail, after adjusting for age, disability, and cognitive function, only volunteering is associated with a lower cumulative odds of frailty.
我们旨在研究参与生产性活动(包括志愿服务、有偿工作和育儿)是否能保护老年人免受老年衰弱的影响。
使用“麦克阿瑟成功老龄化研究”(MacArthur Study of Successful Aging)第一(1988 年)和第二(1991 年)波的数据,这是一项对 70-79 岁高功能老年人进行的前瞻性队列研究(n=1072),检验了这样一个假设,即参与生产性活动与 3 年后衰弱程度较低有关。
在未调整模型中(比值比[OR] = 0.74,95%置信区间[CI] = 0.58-0.96),基线时参与生产性活动与 3 年后衰弱的累积几率较低相关,但在调整年龄、残疾和认知功能后则不相关(调整后的 OR = 0.78,95%CI = 0.60-1.01)。对生产性活动领域的检查表明,调整年龄、残疾和认知功能后,志愿服务(而非有偿工作或育儿)与衰弱的累积几率较低相关。在调整个人掌握和宗教服务参与度后,这种关系减弱且不再具有统计学意义。
尽管参与生产性活动的高功能老年人衰弱的可能性较低,但在调整年龄、残疾和认知功能后,只有志愿服务与较低的衰弱累积几率相关。
