Administration of vitamin D 50,000 units once monthly will: - Maintain serum 25-OH vitamin D above 20 ng/ml - Reduce falls - Increase calcaneal BMD - Reduce bone turnover - Be well tolerated: volunteers will not develop hypercalcemia - Improve performance on a swallowing quality of life questionnaire

Study summary:

1. Research questions: We propose a prospective double-blind, randomized, placebo-controlled trial of once-monthly vitamin D oral capsules (50,000 units) in nursing-home residents. Subjects from several Wisconsin nursing homes were randomized to receive once-monthly vitamin D oral capsules (50,000 units) or placebo. Blood levels of 25-OH D, parathyroid hormone, serum calcium, and a marker of bone turnover will be measured periodically by standard lab assays. Swallowing quality of life was measured by questionnaire. Appropriate statistical tests (paired T tests, 95% confidence intervals will be calculated with the large sample approximation for binomial variables, other).


Inclusion Criteria: - Male or Female - Nursing Home Resident in Wisconsin Exclusion Criteria: - Renal Failure - Hypercalcemia - Metastatic Cancer
