- Abstract
Summary: In this population-based study of more than 2,600 elderly, people with dementia received less preventive treatment for osteoporosis compared to people without dementia, although osteoporotic fractures were more common in patients with dementia. Thus, our results indicate an undertreatment of osteoporosis in dementia. Introduction: This study compares the use of osteoporosis drugs in elderly with and without dementia, taking into account osteoporotic fractures and type of housing. Methods: We analyzed data from the baseline examination (2001-2004) of The Swedish National Study on Aging and Care- Kungsholmen (SNAC-K), Stockholm, Sweden. Participants were aged ≥66 years ( n = 2610). We analysed the use of bisphosphonates, raloxifene, and calcium/vitamin D combinations in relation to clinically based dementia diagnosis. Information about osteoporotic fractures during the previous 4 years was obtained from the Swedish National Patient Register. We used logistic regression to analyze the association between dementia status and use of osteoporosis drugs. Results: Osteoporosis drugs (mainly calcium/vitamin D combinations) were used by 5% of the persons with dementia and 12% of the persons without dementia. Furthermore, 25% of the persons with dementia and 7% of the persons without dementia had had at least one osteoporotic fracture during the past 4 years. After controlling for age, sex, osteoporotic fractures, and type of housing (own home or institution), persons with dementia were less likely to use osteoporosis drugs than persons without dementia (OR = 0.34; 95% CI, 0.19-0.59). Conclusions: Our results indicate an undertreatment of osteoporosis in persons with dementia, although osteoporotic fractures are common among these patients.
