Annotation	In a representative sample of very old subjects, including people living in the community and institutions, this study in Gothenburg, Sweden, showed the prevalence of hip fracture increased in women with dementia, irrespective of cause. Bone density was not associated with dementia or hip fracture. Body mass index and body weight were lower in women with dementia and women with hip fracture. The prevalence of hip fracture was also increased in subjects who used psychotropic drugs, especially tricyclic antidepressants and benzodiazepines. A logistic multiple regression analysis showed that dementia, use of antidepressants and gender independently contributed to hip fracture. The reason for increased risk of hip fractures in those with dementia may be that they have a defective neuromuscular regulation, gait apraxia, use more antidepressants, and have a lower body mass index; surgery and anaesthesia are also implicated.
