Title: Prevention of Falls and Fractures in Old People by Administration of Calcium and Vitamin D. Randomized Clinical Trial (ANVITAD)
Brief Summary: The first objective is to determine the efficacy of calcium and vitamin D supplementation at doses of 1200 mg and 800 IU, respectively, to reduce the incidence of falls and fractures in non-institutionalized elderly people.

The second objective is to measure and compare treatment groups (calcium and vitamin D vs placebo) as regards muscle strength and musculoskeletal function, bone mineral density, calcidiol level and treatment safety.
