Randomized treatments included: vitamin D₃ (cholecalciferol), marine omega-3 fatty acids, or matching placebo. 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).<h4>Results</h4>Among the 11,486 men who provided data at year 2 and 10,474 at year 5, mean age was 68 years at year 2, with 23% racial/ethnic minorities. In primary analyses, vitamin D supplementation compared to placebo did not lower odds of overactive bladder at year 5 (OR 0.97, 95% CI 0.87-1.08) or weekly urinary incontinence at year 2 (OR 0.94, 95% CI 0.83-1.05) or year 5 (OR 0.98, 95% CI 0.88-1.09). We found interactions of baseline serum 25-hydroxyvitamin D level with vitamin D supplementation for overactive bladder (<i>P</i> value for interaction = .001), and secondarily, for any urinary incontinence at year 2 (<i>P</i> value for interaction = .05). Men with baseline 25-hydroxyvitamin D <20 ng/mL, who were assigned to vitamin D supplements, had lower odds of overactive bladder (OR 0.51, 95% CI 0.35-0.76) compared to placebo, yet higher odds of any urinary incontinence (OR 1.24, 95% CI 0.93-1.64).<h4>Conclusions</h4>Overall, vitamin D supplementation did not improve overactive bladder or urinary incontinence compared to placebo. However, specific use of vitamin D in men with lower 25-hydroxyvitamin D levels had inconsistent findings.The Journal of urologyEffect of Vitamin D Supplementation on Overactive Bladder and Urinary Incontinence Symptoms in Older Men: Ancillary Findings From a Randomized Trial.PMC9742141R01 AT011729U01 CA138962R01 CA138962UL1 TR002378K24 AG073586R01 DK115473K24 AG068601Tangpricha VVaughan CPBubes VYManson JECook NRLee IMKim EBuring JRMarkland ADGrodstein FHuang AJfalseEffect of Vitamin D Supplementation on Overactive Bladder and Urinary Incontinence Symptoms in Older Men: Ancillary Findings From a Randomized Trial.<h4>Purpose</h4>Our goal was to evaluate vitamin D supplementation for preventing or treating overactive bladder and urinary incontinence in men.<h4>Materials and methods</h4>Ancillary study of men aged ≥55 years in VITAL (VITamin D and OmegA-3 TriaL).
