To estimate the proportion of U.S. men affected by specific lower urinary tract symptoms (LUTS) and to assess whether the prevalence of LUTS varies by race/ethnicity.


Included were 30+-year-old men who took part in the Third National Health and Nutrition Examination Survey. Men were asked whether they experienced nocturia, incomplete emptying, or hesitancy. Men 60+ years old were also asked whether they had a decreased urinary stream or had ever undergone noncancer prostate surgery. To obtain the estimated prevalences for the U.S. population, we applied sampling fraction weights. We calculated age-adjusted odds ratios (ORs) of 3+ symptoms or surgery by race/ethnicity using logistic regression analysis.


Only nocturia was common in 30 to 59-year-old men. Among men who had not had prostate surgery, 59.9% of men 60 to 69 years old and 75.1% of men 70+ years old had at least one symptom. All four symptoms were reported by 3.0% of men 60 to 69 years and 5.6% of men 70+ years old. Of the men 60 to 69 years old and men 70+ years old, 8.0% and 22.4%, respectively, reported having undergone surgery. In men 60+ years old, the age-adjusted OR for either having 3+ symptoms or surgery was 0.8 for non-Hispanic black men compared with non-Hispanic white men. The odds of having 3+ symptoms (OR = 1.6), but not surgery (OR = 1.1), appeared greater for Mexican-American men than for non-Hispanic white men.


Specific LUTS are common in older U.S. men. Older black men were not more likely to have LUTS than were older white men. The apparent modestly higher prevalence of LUTS in older Mexican-American men requires additional study.
