Study Summary
Vitamin D supplements might substantially reduce the risk of falls, potentially by more than 25%. The proposed study is a clinical trial that will determine the effects of 4 doses of vitamin D (200 International Units \[IU\]/day, 1000 IU/day, 2000 IU/d and 4000 IU/d) as a means to prevent falls in high-risk adults, ages 70 and older. Results of this trial will be directly relevant to public health and clinical guidelines, and will immediately influence policy.
Primary Outcome
Falls were ascertained by a monthly fall calendar completed by each participant, scheduled interviews at 1 month and 3 months after randomization and every 3 months thereafter up to 24 months or trial end. Death was ascertained primarily by reports from family or friends.
