Fall prevention strategies exist, but little is known about factors that influence whether they are used. We assessed whether social isolation modifies the association between fear of falling (FOF) and bathroom environmental modification. Data were included from 2858 Medicare beneficiaries in the National Health and Aging Trends Study. FOF and social isolation were assessed at baseline (2011); new bathroom modifications were assessed 1-year post-baseline. Social network size was dichotomized as any versus no social contacts. Logistic regression assessed associations between FOF and bathroom modification. Effect modification between FOF and social isolation was assessed with multiplicative interaction terms. FOF was associated with increased odds of bathroom modification. We observed a statistically significant interaction between FOF and social isolation ( = 0.03). Among those with no social contacts, FOF was associated with reduced odds bathroom modification that did not reach statistical significance (OR 0.5, 95% CI 0.2-1.3).
存在预防跌倒的策略，但对于影响这些策略是否被采用的因素知之甚少。我们评估了社交孤立是否会改变对跌倒恐惧（FOF）与浴室环境改变之间的关联。数据来自国家健康与老龄化趋势研究中的 2858 名医疗保险受益人。FOF 和社交孤立在基线（2011 年）进行评估；新的浴室改造在基线后 1 年进行评估。社交网络规模分为有社交接触和没有社交接触。逻辑回归评估了 FOF 与浴室改造之间的关联。FOF 和社交孤立之间的效应修饰作用通过乘法交互项进行评估。FOF 与浴室改造的可能性增加有关。我们观察到 FOF 和社交孤立之间存在统计学显著的交互作用（ = 0.03）。在没有社交接触的人群中，FOF 与浴室改造的可能性降低有关，但没有达到统计学意义（OR 0.5，95%CI 0.2-1.3）。
