VITamin D and OmegA-3 TriaL (VITAL) bone health ancillary study: clinical factors associated with trabecular bone score in women and men.

ABSTRACT: We investigated the association of clinical variables with TBS at baseline in the bone health sub-cohort of the VITamin D and OmegA-3 TriaL (VITAL). Lower TBS was associated with female sex, aging, BMI???25 kg/m2, SSRI use, high alcohol intake, and presence of diabetes; there was a trend towards significance between lower TBS and history of fragility fractures. INTRODUCTION:We investigated whether TBS differs by sex, race, body mass index (BMI), and other clinical variables. METHODS:The VITamin D and OmegA-3 TriaL (VITAL) is determining effects of vitamin D3 and/or omega-3 fatty acid (FA) supplements in reducing risks of cancer and cardiovascular disease. In the VITAL: Effects on Bone Structure/Architecture ancillary study, effects of these interventions on bone will be investigated. Here, we examine the associations of clinical risk factors with TBS assessments at baseline in the bone health sub-cohort, comprised of 672 participants (369 men and 303 women), mean (±?SD) age 63.5?±?6.0 years; BMI???37 kg/m2, no bisphosphonates within 2 years or other bone active medications within 1 year. RESULTS:TBS was greater in men than women (1.311 vs. 1.278, P?

Project description:Although supplemental vitamin D is used to promote bone health in the general population, data from randomized controlled trials (RCTs) have been inconsistent. We determined whether daily, vitamin D3 supplementation improves bone mineral density (BMD) and/or structure. VITamin D and OmegA-3 TriaL (VITAL) is a double-blind, placebo-controlled RCT of supplemental vitamin D3 (2000 IU/d) and/or omega-3 fatty acids (1 g/d) in 25,871 adults nationwide. This ancillary study included a subcohort of 771 participants (men ≥50 and women ≥55 years; not taking bone active medications) evaluated at baseline and at 2-year follow-up (89% retention). Total 25(OH)D levels were measured by liquid chromatography tandem mass spectrometry (Quest Diagnostics, San Juan Capistrano, CA, USA). Free 25(OH)D (FVD) levels were measured using the ELISA assay by Future Diagnostics Solutions BV (Wijchen, Netherlands). Primary endpoints were 2-year changes in areal (a) BMD at the spine, hip, and whole body determined by dual-energy X-ray absorptiometry (DXA). Secondary endpoints were 2-year changes in volumetric (v) BMD and cortical thickness at the radius and tibia assessed by peripheral quantitative computed tomography. Supplemental vitamin D3 versus placebo had no effect on 2-year changes in aBMD at the spine (0.33% versus 0.17%; p = 0.55), femoral neck (-0.27% versus -0.68%; p = 0.16), total hip (-0.76% versus -0.95%; p = 0.23), or whole body (-0.22% versus -0.15%; p = 0.60), or on measures of bone structure. Effects did not vary by sex, race/ethnicity, body mass index, or 25(OH)D levels. Among participants with baseline FVD levels below the median (<14.2 pmol/L), there was a slight increase in spine aBMD (0.75% versus 0%; p = 0.043) and attenuation in loss of total hip aBMD (-0.42% versus -0.98%; p = 0.044) with vitamin D3 . Whether baseline FVD levels help to identify those more likely to benefit from supplementation warrants further study. Supplemental vitamin D3 versus placebo for 2 years in general healthy adults not selected for vitamin D insufficiency did not improve BMD or structure. © 2020 The Authors.
