    Abstract:
    BACKGROUND: Aged residents in nursing homes are at particularly high risk of fractures. Vitamin D and calcium have a preventative role. OBJECTIVE: To describe the use of vitamin D and calcium supplementations, and their association with nutritional factors among nursing home residents. METHODS: Our study is a cross-sectional assessment of long-term residents in all nursing homes in Helsinki during February 2003. We collected residents' background information, nutritional status (Mini Nutritional Assessment, MNA), and data on daily nursing routines in institutions, including nutritional care. Vitamin D and calcium supplementations were inquired after in the questionnaire and retrieved from residents' medication lists. RESULTS: 2,114 (87%) of all 2,424 eligible residents had available data on the use of vitamin D and calcium supplementation. Their mean age was 83 years, and 80.7% were female. Of all participants, 32.9% received vitamin D supplementation and 27.7% calcium supplementation. Altogether 20.0% received both. However, only 21.3% received vitamin D in the therapeutic dose of 10 mg (400 IU) or more, and 3.6% in the recommended dose of 20 microg (800 IU) or more. In logistic regression analysis, residents who received vitamin D supplementation also had better nutritional status (MNA), ate snacks between meals, did not have constipation and their weight was checked more frequently. CONCLUSIONS: Regardless of the known benefit and recommendation of vitamin D supplementation for the elderly residing mostly indoors, the proportion of nursing home residents receiving vitamin D and calcium was surprisingly low.
