%X In our cluster randomised controlled trial for efficacy of hip protector with 672 ambulatory elderly women, a hip protector was more effective for prevention of hip fractures in residents with fall history (n = 202; hazard ratio (HR), 0.375; 95%CI, 0.14-0.98; p = 0.05) and body-mass index (BMI) &lt;/= 19.0 (n = 206; HR, 0.37; 95%CI, 0.14-0.95; p = 0.04) by a Cox proportional hazards regression model. INTRODUCTION: Hip fractures result from both osteoporosis and falling. A potentially cost-effective method of preventing hip fractures involves the use of hip protectors but recent studies have revealed the uncertain effectiveness of hip protectors even in institutional settings. METHODS: This study was a cluster randomised controlled trial with nursing homes. We randomly assigned 76 homes with 672 ambulatory but frail elderly women. Several risk factors were assessed at baseline and incorporated into a Cox proportional hazards regression model. UMIN Clinical Trials Registry number is UMIN000000467. Research period was between January 2004 and March 2006. RESULTS: In the intervention group, 19 hip fractures occurred (54.0/1,000 person-years), whereas 39 hip fractures occurred in the control group (78.8/1,000 person-years). Hazard ratio of hip fracture in the intervention group was 0.56 (95%CI, 0.31-1.03; p = 0.06) after adjusting for risk factors. In subgroup analysis, hip protectors were more effective for prevention of hip fractures in residents with fall history (n = 202; HR, 0.375; 95%CI, 0.14-0.98; p = 0.05) and BMI &lt;/= 19.0 (n = 206; HR, 0.37; 95%CI, 0.14-0.95; p = 0.04). Overall compliance with use of hip protectors was 79.7%. CONCLUSION: Risk of hip fracture can be reduced by hip protectors among elderly women with fall history and low BMI. <p p="0.04)" overall="overall" compliance="compliance" use="use" was="was" conclusion:="conclusion:" risk="risk" of="of" fracture="fracture" can="can" be="be" reduced="reduced" by="by" hip="hip" protectors="protectors" among="among" elderly="elderly" women="women" with="with" fall="fall" history="history" and="and" low="low"></p><p>Language: en</p>
