Hip fractures and Alzheimerʹs disease in elderly institutionalized Canadians

Purpose To examine the associations among Alzheimerʹs disease, hip fractures, and falls in elderly Canadians greater-or-equal, slanted65 years of age (n = 1513) who participated in the National Population Health Survey for Health Institutions between 1994 and 1995. Methods The survey was designed to provide health-related information for residents of Canadian health institutions. Logistic regression analysis was used to assess the association between hip fractures and Alzheimerʹs Disease (AD). Covariates assessed included osteoporosis, age, sex, medications, and comorbid conditions. We did an additional analysis confined to participants who fell, in an attempt to tease out the contribution of falling to the relation between AD and hip fractures. Results The adjusted odds ratio relating Alzheimerʹs disease to hip fracture was 2.18 (95% CI: 1.26–3.79). Among those who reported falling, the adjusted odds ratio relating Alzheimerʹs disease to hip fracture was 1.78 (95% CI: 1.01–3.14). Conclusions The most important finding in this study is the independent relation between Alzheimerʹs disease and hip fractures.
