Abstract

Objectives: To compare the effects of 12 months of vitamin D 3 supplementation with that placebo on lean mass, bone mineral density ( BMD ), and muscle strength in overweight or obese postmenopausal women completing a structured weight‐loss program. Design: Double‐blind, placebo‐controlled randomized clinical trial. Setting: Fred Hutchinson Cancer Research Center, Seattle, Washington. Participants: Postmenopausal women aged 50 to 75 with a body mass index ( BMI ) of 25 kg/m 2 or greater and a serum 25‐hydroxyvitamin D (25(OH)D) concentration between 10.0 and 32.0 ng/mL (insufficient) (N = 218). Intervention: Oral vitamin D 3 2,000 IU/d or placebo in combination with a lifestyle‐based weight loss intervention consisting of a reduction of 500 kcal to 1,000 kcal per day and 225 min/wk of moderate‐ to vigorous‐intensity aerobic exercise. Measurements: Serum 25(OH)D, body composition, and muscle strength were measured before randomization (baseline) and at 12 months. Mean changes of the groups were compared (intention to treat) using generalized estimating equations. Results: Change in 25(OH)D was significantly different between the vitamin D and placebo groups at 12 months (13.6 ng/mL vs −1.3 ng/mL, P < .001), but no differences in change in lean mass (−0.8 kg vs −1.1 kg, P = .53) or BMD of the spine (−0.01 g/cm 2 vs 0.0 g/cm 2 , P = .82) or right femoral neck (both −0.01 g/cm 2 , P = .49) were detected between the groups. Leg strength decreased in the vitamin D group but not in the placebo group (−2.6 pounds vs 1.8 pounds, P = .03). In women randomized to vitamin D, achieving repletion (25(OH)D ≥ 32 ng/mL) did not alter results. Conclusion: Vitamin D 3 supplementation during weight‐loss decreased leg strength but did not alter changes in lean mass or BMD in postmenopausal women with vitamin D insufficiency.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
