Effect of Vitamin D Supplementation on Overactive Bladder and Urinary Incontinence Symptoms in Older Men: Ancillary Findings From a Randomized Trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

Who Took Part

The age groups tagged for this paper are older adults.

Ancillary study of men aged ≥55 years in VITAL (VITamin D and OmegA-3 TriaL).

Randomized treatments included: vitamin D3 (cholecalciferol), marine omega-3 fatty acids, or matching placebo.

How the Study Was Run

The design is described as randomized and placebo-controlled.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

Structured urinary incontinence questions measured the prevalence of overactive bladder at year 5 and urinary incontinence at years 2 and 5, along with incidence and progression of urinary incontinence from years 2 to 5.

Prespecified subgroup analyses examined men with low baseline serum 25-hydroxyvitamin D (<20 ng/mL).
