Although foot pain has been linked to fall risk, contributions of pain severity, foot posture, or foot function are unclear. These factors were examined in a cohort of older adults.
The purpose of this study was to examine the associations of foot pain, severity of foot pain, and measures of foot posture and dynamic foot function with reported falls in a large, well-described cohort of older adults from the Framingham Foot Study.
Foot pain, posture, and function were collected from Framingham Foot Study participants who were queried about falls over the past year (0, 1, and ≥2 falls). Logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for the relation of falls with foot pain, pain severity, foot posture, and foot function adjusting for covariates.
The mean age of the 1,375 participants was 69 years; 57% were female, and 21% reported foot pain (40% mild pain, 47% moderate pain, and 13% severe pain). One-third reported falls in the past year (1 fall: n = 263, ≥2 falls: n = 152). Foot pain was associated with a 62% increased odds of recurrent falls. Those with moderate and severe foot pain showed increased odds of ≥2 falls (OR 1.78, CI 1.06-2.99, and OR 3.25, CI 1.65-7.48, respectively) compared to those with no foot pain. Foot function was not associated with falls. Compared to normal foot posture, those with planus foot posture had 78% higher odds of ≥2 falls.
Higher odds of recurrent falls were observed in individuals with foot pain, especially severe foot pain, as well as in individuals with planus foot posture, indicating that both foot pain and foot posture may play a role in increasing the risk of falls among older adults.
尽管足部疼痛与跌倒风险相关，但疼痛严重程度、足部姿势或足部功能的作用尚不清楚。在一组老年人中对这些因素进行了研究。
本研究的目的是在弗雷明汉姆足部研究中一个规模大、描述详细的老年人群队列中，研究足部疼痛、足部疼痛严重程度以及足部姿势和动态足部功能指标与报告的跌倒之间的关联。
从弗雷明汉姆足部研究参与者中收集足部疼痛、姿势和功能数据，这些参与者被询问过去一年的跌倒情况（0次、1次和≥2次跌倒）。使用逻辑回归计算跌倒与足部疼痛、疼痛严重程度、足部姿势和足部功能之间关系的比值比（OR）和95%置信区间（CI），并对协变量进行调整。
1375名参与者的平均年龄为69岁；57%为女性，21%报告有足部疼痛（40%为轻度疼痛，47%为中度疼痛，13%为重度疼痛）。三分之一的人报告在过去一年中有跌倒（1次跌倒：n = 263，≥2次跌倒：n = 152）。足部疼痛与跌倒复发几率增加62%相关。与无足部疼痛的人相比，中度和重度足部疼痛的人≥2次跌倒的几率增加（分别为OR 1.78，CI 1.06 - 2.99和OR 3.25，CI 1.65 - 7.48）。足部功能与跌倒无关。与正常足部姿势相比，扁平足姿势的人≥2次跌倒的几率高78%。
在有足部疼痛的个体中，尤其是重度足部疼痛的个体，以及扁平足姿势的个体中，观察到跌倒复发几率更高，这表明足部疼痛和足部姿势都可能在增加老年人跌倒风险中起作用。
