A longitudinal analysis using a population-based cohort study known as Research on Osteoarthritis/osteoporosis Against Disability (ROAD) clarified the associations of physical performance and bone and joint diseases with falls. A total of 452 men and 896 women were analyzed in the present study (mean age, 63.9 years) . A questionnaire was used to assess the number of falls during the 3-year follow-up. Grip strength, 6-m walking time, and chair stand time were measured at baseline. Knee osteoarthritis (OA) and lumbar spondylosis were defined as Kellgren Lawrence = 3 or 4. Vertebral fracture (VFx) was assessed with the Japanese Society of Bone and Mineral Research criteria. Knee and lower back pain were estimated by an interview. During a 3-year follow-up, 17.4% men and 24.1% women reported at least one fall. Multinomial logistic regression analysis after adjustment for age and BMI showed that a longer 6-m walking time was a risk factor for multiple falls in men and women. Knee pan was also a risk factor for multiple falls in women. Walking time and knee pain may be a simple and quick option for measuring the risk of falling.
一项基于人群队列研究的纵向分析，即骨关节炎/骨质疏松症抗残疾研究（ROAD），阐明了身体机能以及骨骼和关节疾病与跌倒之间的关联。本研究共分析了452名男性和896名女性（平均年龄63.9岁）。通过问卷调查评估3年随访期间的跌倒次数。在基线时测量握力、6米步行时间和从椅子上站起的时间。膝关节骨关节炎（OA）和腰椎病定义为凯尔格伦·劳伦斯分级为3级或4级。根据日本骨与矿物质研究学会的标准评估椎体骨折（VFx）。通过访谈评估膝关节和下背部疼痛情况。在3年随访期间，17.4%的男性和24.1%的女性报告至少发生过一次跌倒。在对年龄和体重指数进行调整后的多项逻辑回归分析显示，6米步行时间较长是男性和女性多次跌倒的危险因素。膝关节疼痛也是女性多次跌倒的危险因素。步行时间和膝关节疼痛可能是评估跌倒风险的简单快捷方法。
