To examine the relationship between social capital and depression among community-dwelling older adults in Anhui Province, China.
A cross-sectional study was conducted among older people selected from three cities of Anhui Province, China using a multi-stage stratified cluster random sampling method. Data were collected through questionnaire interviews and information on demographic characteristics, social capital, and depression was collected. The generalized linear model and classification and regression tree model were employed to assess the association between social capital and depression.
Totally, 1810 older people aged ≥60 years were included in the final analysis. Overall, all of the social capital dimensions were positively associated with depression: social participation (coefficient: 0.35, 95% CI: 0.22-0.48), social support (coefficient:0.18, 95% CI:0.07-0.28), social connection (coefficient: 0.76, 95% CI:0.53-1.00), trust (coefficient:0.62, 95% CI:0.33-0.92), cohesion (coefficient:0.31, 95% CI:0.17-0.44) and reciprocity (coefficient:0.30, 95% CI:0.11-0.48), which suggested that older people with higher social capital had a smaller chance to develop depression. A complex joint effect of certain social capital dimensions on depression was also observed. The association with depression and the combinative effect of social capital varied among older adults across the cities.
Our study suggests that improving social capital could aid in the prevention of depression among older adults.
探讨中国安徽省社区老年居民社会资本与抑郁之间的关系。
采用多阶段分层整群随机抽样方法，对来自中国安徽省三个城市的老年人进行横断面研究。通过问卷调查收集数据，收集人口统计学特征、社会资本和抑郁方面的信息。采用广义线性模型和分类回归树模型评估社会资本与抑郁之间的关联。
最终纳入分析的≥60岁老年人共1810名。总体而言，所有社会资本维度均与抑郁呈正相关：社会参与（系数：0.35，95%置信区间：0.22-0.48）、社会支持（系数：0.18，95%置信区间：0.07-0.28）、社会联系（系数：0.76，95%置信区间：0.53-1.00）、信任（系数：0.62，95%置信区间：0.33-0.92）、凝聚力（系数：0.31，95%置信区间：0.17-0.44）和互惠性（系数：0.30，95%置信区间：0.11-0.48），这表明社会资本较高的老年人患抑郁症的机会较小。还观察到某些社会资本维度对抑郁有复杂的联合效应。不同城市的老年人中，社会资本与抑郁的关联及联合效应各不相同。
我们的研究表明，提高社会资本有助于预防老年人抑郁。
