Social inactivity predicts adverse health events, but less is known about how different dimensions of social activity are related to health. The aim of this study was to investigate collective (e.g., cultural and organizational activities) and productive (e.g., helping others) social activity as predictors of risk for mortality and institutionalization in old age.
A total of 1,181 community-living people aged 65-84 years at baseline were interviewed face to face as part of the Evergreen project, in Jyväskylä, Finland in 1988. Time to institutionalization and mortality were analyzed in separate models for proportional hazard regression on mortality and competing risks analysis on institutionalization and mortality.
At follow-up, approximately 17 years later, 22% of persons were institutionalized and 71% had died. When sociodemographics, health, functioning, and intensity of physical activity were controlled for, collective social activity reduced risk for mortality and initially for institutionalization although this latter effect diminished over time.
Collective social activity may be associated with a reduced risk for mortality and institutionalization in older people. Further studies on the mechanisms underlying the association between social activity and health are needed.
社会活动不足可预测不良健康事件，但对于不同维度的社会活动与健康的关系知之甚少。本研究旨在探讨集体（如文化和组织活动）和生产性（如帮助他人）社会活动与老年人死亡和入院风险的关系。
1988 年，在芬兰于韦斯屈莱的常青项目中，共有 1181 名 65-84 岁的社区居住者接受了面对面访谈。使用比例风险回归分析死亡率和竞争风险分析入院和死亡率，分别对入院和死亡率进行了分析。
在随访中，大约 17 年后，22%的人被收容入院，71%的人死亡。当控制了社会人口统计学、健康、功能和身体活动强度后，集体社会活动降低了死亡风险，并最初降低了入院风险，尽管这种影响随着时间的推移而减弱。
集体社会活动可能与老年人死亡和入院风险降低有关。需要进一步研究社会活动与健康之间关联的潜在机制。
