MONDAY, June 9 (HealthDay News) -- Nocturia -- defined as two or more voidings per night -- may be associated with obstructive sleep apnea in men younger than age 50, according to the results of a study published in the June issue of Urology.
Yoji Moriyama, M.D., of Gifu University Hospital in Gifu, Japan, and colleagues assessed 73 patients who were diagnosed with obstructive sleep apnea between October 2005 and April 2006, and classified the group by presence or absence of nocturia and by age: younger than age 50 and age 50 or older.
The researchers identified nocturia in eight patients (27.6 percent) under age 50 and in 22 patients (50 percent) aged 50 or older. They found that the mean Apnea-Hypopnea Index was significantly higher in patients under age 50 with nocturia compared to those without nocturia (86 versus 43, respectively) but not in men older than age 50 with or without nocturia.
"The findings of our study suggest that obstructive sleep apnea syndrome should be taken into consideration for patients less than 50 years of age who complain of nocturia," the authors conclude.
