Prevalence, risk factors and the bother of lower urinary tract symptoms in China: a population-based survey.
Int Urogynecol J. 2015 Jun; 26(6):911-9.IU

Abstract

INTRODUCTION AND HYPOTHESIS

Lower urinary tract symptoms (LUTS) consist of storage, voiding and postmicturition symptoms and cause discomfort in approximately 15.8 to 82.0 % of adults worldwide. Despite the wide range in prevalence rates, certain potential risk factors for LUTS have been identified, advanced age being the most noted one. However, the true extent of symptom discomfort among the affected population may be underestimated because of the considerable underreporting of the problem. The objective of this study was to evaluate the prevalence, risk factors and discomfort caused by LUTS in China.

METHODS

This population-based, cross-sectional survey was conducted in five geographical regions of China. A stratified, clustered, systematic sample of individuals aged ≥18 years was selected to answer demographic questionnaires and the International Consultation on Incontinence Questionnaire Male/Female Lower Urinary Tract Symptoms Long Form.

RESULTS

A total of 3,023 participants (1,551 men; 1,472 women) were included in this study, and 61.2 % (61.2 % men; 61.1 % women) reported at least one LUTS. The prevalence of storage symptoms (59.8 % men; 60.5 % women) was greater than that of voiding (23.6 % men; 8.8 % women) plus postmicturition symptoms (14.6 % men; 6.3 % women). Nocturia (58.2 % men; 56.9 % women) was the most common specific LUTS. Advanced age, alcohol consumption and smoking were risk factors for LUTS among participants of both sexes. Enlarged prostate, diabetes mellitus and lower education levels correlated positively with LUTS in men, whereas higher parity and hypertension correlated positively with LUTS in women. Subjects with LUTS had great discomfort. Nocturia was the least bothersome symptom in both sexes, whereas nocturnal enuresis and urge urinary incontinence were the most bothersome in men and women respectively.

CONCLUSIONS

Lower urinary tract symptoms are highly prevalent in China and many known risk factors are associated with these bothersome symptoms. However, the perception of the extent of symptom discomfort differed between sexes, and it may not correspond with symptom prevalence. Thus, an appropriate symptom discomfort assessment tool is needed to identify the clinically relevant conditions that warrant treatment.
