One of the greatest challenges of old age is the risk of cognitive decline. Engagement in social activities has been identified as a possible protective factor. However, it is not yet clear what are the mechanisms underlying this association. This study aims to elucidate the pathways through which social activities impact cognitive functioning, focusing on physical activity and mental health as possible mediators.
The study utilized 3 waves of data-the fourth, fifth, and sixth waves of the Survey of Health, Ageing and Retirement in Europe, collected in 2011, 2013, and 2015, respectively. It focused on respondents aged 60 and older. Cognitive functioning was assessed via immediate recall, delayed recall, and fluency. Social activities were measured by volunteering and attending social clubs. Data were analyzed using a structural equation modeling approach.
The results indicated a significant direct effect of social activities on cognitive functioning. That is, being socially active at baseline was related to better cognitive function 4 years later. The results also indicated the existence of indirect effects. Engaging in social activities was related to better mental health and more physical activities 2 years later, which were related to better subsequent cognitive performance.
These findings highlight the mediating roles of physical activity and mental health in the effects of social activities on cognitive functioning. Understanding these mechanisms can help optimize social activity interventions to improve cognitive aging.
老年面临的最大挑战之一是认知能力下降的风险。参与社交活动已被确定为一种可能的保护因素。然而,这种关联背后的机制尚不清楚。本研究旨在阐明社交活动影响认知功能的途径,重点关注身体活动和心理健康作为可能的中介因素。
该研究使用了三轮数据——分别于2011年、2013年和2015年收集的欧洲健康、老龄化与退休调查的第四波、第五波和第六波数据。研究重点关注60岁及以上的受访者。认知功能通过即时回忆、延迟回忆和流畅性进行评估。社交活动通过志愿服务和参加社交俱乐部来衡量。数据采用结构方程建模方法进行分析。
结果表明社交活动对认知功能有显著的直接影响。也就是说,在基线时社交活跃与4年后更好的认知功能相关。结果还表明存在间接影响。参与社交活动与2年后更好的心理健康和更多的身体活动相关,而这又与随后更好的认知表现相关。
这些发现突出了身体活动和心理健康在社交活动对认知功能影响中的中介作用。理解这些机制有助于优化社交活动干预措施以改善认知老化。
