跌倒和跌倒恐惧(FOF)是老年人功能受限的独立危险因素。然而，FLOWS和FOF在功能限制以及独居或非独居的调节作用方面的联合作用尚不清楚。我们的目标是研究(1)跌倒和FOF对老年人功能限制的独立和联合影响，以及(2)独居是否缓和了这些联系。我们使用了来自国家健康和老龄化趋势研究(NHATS)的数据，包括第一轮(2011年)和第二轮(2012年)的5950名65岁及以上的美国社区居住老年人。通过询问参与者在过去一年中是否有任何跌倒，以及他们是否担心前一个月在R1摔倒，确定了跌倒和FOF。评估的功能限制包括R2在行动、自我照顾或家庭活动方面的任何困难。泊松回归模型被用来检验跌倒和FOF与功能限制和基线独居的缓和效应之间的纵向联系。在5950名参与者中，16.3%的人只有跌倒；14.3%的人只有FOF；14.3%的人两者都有，55.1%的人在基线时都没有。在调整后的模型中，同时发生摔倒和FOF的患者发生R2功能障碍的风险比没有发生的患者更高(活动能力：发生率风险比[IRR]=1.34，95%CI：1.24~1.45；自理：IRR=1.18，95%CI：1.11~1.26；家庭：IRR=1.20，95%CI：1.11~1.30)。此外，独居显著缓和了同时跌倒和FOF与活动受限的纵向关联。这些发现表明，同时改善FLOWS和FOF的策略可能有助于防止功能限制。与他人生活在一起并有跌倒或FOF的老年人应该接受干预，以促进他们的行动能力。
Falls and fear of falling (FOF) are independent risk factors for functional limitations in older adults. However, the combined effect of falls and FOF on functional limitations and the moderating role of living alone or not is unclear. We aimed to examine (1) the independent and combined effect of falls and FOF on functional limitations in older adults and (2) whether living alone moderates these associations. We used data from the National Health and Aging Trends Study (NHATS) and included 5,950 U.S. community-dwelling older adults aged 65 and older from Round 1 (Year 2011) and Round 2 (Year 2012). Falls and FOF were ascertained by asking participants whether they had any falls in the last year and whether they had worried about falling in the previous month at R1. Assessed functional limitations included any difficulties with mobility, self-care, or household activities at R2. Poisson regression models were used to examine the longitudinal associations of falls and FOF with functional limitations and the moderation effects of baseline living alone. Of the 5,950 participants, 16.3% had falls only; 14.3% had FOF only; 14.3% had both, and 55.1% had neither at baseline. In the adjusted model, those who experienced concurrent falls and FOF in R1 had a higher risk of functional limitations at R2 than those with neither (Mobility: Incidence risk ratio [IRR] = 1.34, 95% CI: 1.24–1.45; Self-care: IRR = 1.18, 95% CI: 1.11–1.26; Household: IRR = 1.20, 95% CI: 1.11–1.30). Moreover, living alone significantly moderated the longitudinal associations of concurrent falls and FOF with mobility activity limitations. The findings suggest that strategies to improve falls and FOF together could potentially help prevent functional limitations. Older adults who live with others and have falls or FOF should receive interventions to promote their mobility activities.
