身体活动和身体表现与老年人的跌倒风险有关。作者在男性骨质疏松性骨折研究中检查了身体活动和身体表现与事件福尔斯之间的关系，该研究是一项大型前瞻性队列研究，涉及美国5，995名至少65岁的社区居住男性。作者还研究了哪些类型的活动与跌倒有关。2000年至2005年之间的事件福尔斯被捕获的17个三年一次的后续调查问卷，每个参与者和广义估计方程进行了分析。平均随访4.5年。在随访的前4个月，跌倒的平均风险为6.6%。最活跃的四分位数的跌倒风险显著高于最不活跃的四分位数（相对风险= 1.18，95%置信区间（CI）：1.07，1.29）。腿部力量和握力较大的男性跌倒风险显著降低（最高腿部力量四分位数与最低腿部力量四分位数：相对风险= 0.82，95% CI：0.73，0.92;最高握力四分位数与最低握力四分位数：相对风险= 0.76，95% CI：0.69，0.85）。活动的划分成分显示跌倒风险与休闲活动之间没有关联，但与家庭活动呈正相关（最高四分位数与最低四分位数：相对风险= 1.17，95%CI：1.07，1.28）。
Physical activity and physical performance have been linked to fall risk in the elderly. The authors examined the relation between physical activity and physical performance with incident falls in the Osteoporotic Fractures in Men Study, a large prospective cohort study of 5,995 community-dwelling men in the United States at least 65 years of age. The authors also examined what types of activities are associated with falling. Incident falls between 2000 and 2005 were captured from up to 17 triannual follow-up questionnaires per participant and analyzed with generalized estimating equations. Follow-up averaged 4.5 years. The average risk of falling in the first 4 months of follow-up was 6.6%. The most active quartile had a significantly greater fall risk than did the least active quartile (relative risk = 1.18, 95% confidence interval (CI): 1.07, 1.29). Men with greater leg power and grip strength had significantly reduced fall risk (for highest leg power quartile vs. lowest: relative risk = 0.82, 95% CI: 0.73, 0.92; for highest grip strength quartile vs. lowest: relative risk = 0.76, 95% CI: 0.69, 0.85). Partitioning components of activity showed no association between fall risk and leisure activities but a positive association with household activities (for highest quartile vs.lowest: relative risk = 1.17, 95% CI: 1.07, 1.28).
