This study examined the moderating influences of active social networks (ASN), sedentary social networks (SSN) and ASN lost on the relationship between neighbourhood walkability and social activity in community-dwelling older adults aged 60 years or more in Accra, Ghana. A total of 863 individuals participated after G*Power 3.1 was utilized to calculate the minimum sample size. We analysed the data with Pearson's correlation test and hierarchical linear regression models. A sensitivity analysis was conducted to select the ultimate confounding variables. The study found a positive influence of neighbourhood walkability on social activity after the covariate adjustment (β = 0.18; t = 5.2; p = 0.000). The positive influence of neighbourhood walkability on social activity was significantly reduced by ASN lost and SSN. ASN did not have a significant moderating influence on the primary relationship. The study concludes that the positive influence of walkable neighbourhoods on social activity decreases as SSN and ASN lost increase.
本研究考察了积极社交网络（ASN）、久坐社交网络（SSN）和 ASN 丧失对加纳阿克拉市 60 岁及以上社区居住老年人的邻里可步行性与社交活动之间关系的调节作用。在使用 G*Power 3.1 计算最小样本量后，共有 863 人参与了研究。我们使用 Pearson 相关检验和层次线性回归模型分析了数据。进行敏感性分析以选择最终的混杂变量。研究发现，在调整协变量后，邻里可步行性对社交活动有积极影响（β=0.18；t=5.2；p=0.000）。ASN 丧失和 SSN 显著降低了邻里可步行性对社交活动的积极影响。ASN 对主要关系没有显著的调节作用。研究得出结论，随着 SSN 和 ASN 丧失的增加，邻里可步行性对社交活动的积极影响会降低。
