Consumption of the amount of caffeine in two cups of coffee increases the likelihood of urinary incontinence (UI) in men, a study found.

In a study of men who participated in the 2005-2006 and 2007-2008 National Health and Nutritional Examination Survey, researchers found that caffeine intake in the upper 75th percentile (234 mg/day or more) and 90th percentiles (392 mg/day or more) was significantly associated with a 72% and twofold increased risk of having moderate-to-severe UI, respectively, reports reported online ahead of print in The Journal of Urology. The effect size of the association remained after adjusting for prostate conditions.

The study, led by Alayne Markland, MD, of the University of Alabama in Birmingham, looked at data from 3,960 men aged 20 years or older who had complete data. Of these, 12.9% had UI. Men with an Incontinence Severity Index score of 3 or higher were considered to have moderate-to-severe UI.
