在佛罗里达达尼丁退休社区的一个大型队列（N = 3110）中进行了一项前瞻性研究，以确定定期休闲时间体力活动（包括休闲散步）是否与骨折风险相关。队列中63%为女性，均为白色，平均年龄为73.0岁± 5.3岁（SD）。基线时定期进行体力活动的参与者骨折风险降低;男性和女性骨折风险比（RR）分别为RR = 0.41，95%CI = 0.17 ~ 1.01和RR = 0.76，95%CI = 0.50 ~ 1.15。每周3次至少1英里的步行似乎对两性都有保护作用。在控制了潜在的混杂变量（包括体重和选定的健康状况）后，男性和女性定期体力活动对骨折发生率的RR基本保持不变。我们的结论是，定期的身体活动，如散步，可以防止老年人骨折。
A prospective study to determine if regular leisure-time physical activity (including recreational walking) is associated with fracture risk was conducted in a large cohort (N = 3110) of free-living elderly men and women in the retirement community of Dunedin, Florida. Sixty-three percent of the cohort was female, all were white, and the average age was 73.0 years ± 5.3 (SD). Participants in regular physical activity at baseline had a reduced risk of fracture; the risk ratio (RR) of fracture for men and women, respectively, was RR = 0.41,95% CI = 0.17 to 1.01 and RR = 0.76, 95% CI = 0.50 to 1.15. Walking at least one mile 3 times/week appeared to offer a protective effect for both sexes. After controlling for potentially confounding variables including body mass and selected health conditions, the RR for regular physical activity on fracture incidence in men and women remained essentially unchanged. We conclude that regular physical activity such as walking may protect against fracture in older persons.
