Physical Activity, Nocturia Inversely Linked

(HealthDay News) — Men who are physically active are less likely to report nocturia, commonly associated with benign prostatic hyperplasia (BPH), according to a study published online July 9 in Medicine & Science in Sports & Exercise.

Kathleen Y. Wolin, ScD, from Loyola University Chicago, and colleagues examined the association of physical activity (PA) with BPH-related outcomes and nocturia among participants in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. The correlation was examined with both prevalent (28,404 cases) and incident (4,710 cases) BPH-related outcomes.

The researchers observed a weak positive association for PA with several prevalent BPH-related outcomes, and a strong inverse association with prevalent nocturia. In incident analyses, the only association was for PA with nocturia. Compared with men who reported no PA, those who were active one or more hours/week were 13 and 34% less likely to report nocturia and severe nocturia, respectively. For men with and without additional BPH-related outcomes, the associations were similar, except for prevalent nocturia where the correlation was stronger for men without other BPH-related outcomes.

“Combined with other management strategies, PA may provide a strategy for the management of BPH-related outcomes, particularly nocturia,” the authors write.
