VITamin D and OmegA-3 TriaL (VITAL): Fractures, Vitamin D and Genetic Markers
August 7, 2023 updated by: Meryl LeBoff, Brigham and Women's Hospital
The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a randomized clinical trial in 25,871 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses.
This ancillary study is being conducted among participants in VITAL and will examine (1) whether vitamin D reduces incident total, non-vertebral fractures, and hip fractures and (2) whether this reduction is modified by vitamin D levels

Detailed Description
The VITAL: Vitamin D, Fractures, and Genetic Markers is an ancillary study of the parent VITAL trial (VITamin D and OmegA-3 TriaL).
The study will require the adjudication of all self-reported incident fracture events among 25,871 men and women.
Findings from this ancillary study will inform clinical practice on the role(s) of vitamin D supplements in fracture prevention.
This proposal will generate important positive or informative negative results about effects of supplemental vitamin D3 alone on fracture risk, while also elucidating the relative importance of vitamin D biomarkers and genetic variations in vitamin D-related pathways on bone.
Findings from the proposed ancillary study have the potential for major clinical as well as public health impact for both men and women in the U.S.
