LUTS prevalent among adults in China, Taiwan, South Korea
The prevalence of lower urinary tract symptoms (LUTS) is high in Chinese, Taiwanese and South Korean populations, and further increases with age, according to a new population-based study.
In a survey of 8,284 adults (≥40 years of age; 50.8 percent female), the prevalence of LUTS, as determined by the International Continence Society (ICS) 2002 criteria, was significantly higher in South Korea (68.2 percent) than in China (59.0 percent) and Taiwan (58.5 percent; p=0.001).
The combination of voiding, storage and postmicturation symptoms were present in 35 percent of the study sample. In contrast, voiding or postmicturation symptoms alone were in 7.3 and 3.0 percent, respectively. Storage symptoms frequently occurred alone and were observed in 29.9 percent of LUTS patients.
LUTS were significantly more common in males (62.8 percent) than in females (59.7 percent; p=0.004). Voiding and postmicturation symptoms were also more prevalent in males (7.2 and 2.1 percent, respectively) than in females (1.8 and 1.6 percent, respectively). Storage symptoms were more common in females (23.8 percent) than in males (12.6 percent).
Individuals above the age of 60 had a significantly higher prevalence of LUTS than those in the 40 to 44 age group (69.7 vs 49.9 percent; p=0.001).
In terms of comorbidities, diabetes and neurological diseases yielded the greatest increases in the risk of LUTS compared with individuals without the comorbidity (26.5 and 26.1 percent increase, respectively).
Tested and verified internet surveys were administered to the selected participants; questions included international prostate symptom scores and ICS definitions. Endpoints of the study were LUTS prevalence in the entire study sample and across different sociodemographic groups.
