This study aimed to determine whether the incidence of hip fracture is greater among those living in institutions compared with those living in private homes. Over two and a half years of surveillance, 1832 hip fractures were identified, of which 58% were sustained by those living in private homes and 42% by those living in institutions. The risks of hip fracture, unadjusted for age and sex, were 10.5 times greater for those living in institutions compared with those living in private homes. After adjusting for age and sex, these greatly increased risks were maintained, although for both men and women the risks decreased with age, such that at ages over 90 years the risks were not significantly different. Given these findings, hip fracture prevention strategies that focus particularly on individuals within institutions are highly commended.
本研究旨在确定居住在养老院的人群与居住在私人住宅的人群相比，髋部骨折的发生率是否更高。在超过两年半的监测期内，共识别出1832例髋部骨折，其中58%发生在居住在私人住宅的人群中，42%发生在居住在养老院的人群中。在未对年龄和性别进行调整的情况下，居住在养老院的人群发生髋部骨折的风险是居住在私人住宅人群的10.5倍。在对年龄和性别进行调整后，这种大幅增加的风险仍然存在，尽管男性和女性的风险都随着年龄的增长而降低，以至于在90岁以上时，风险没有显著差异。基于这些发现，强烈推荐特别关注养老院人群的髋部骨折预防策略。
