Abstract

Hypothesis / aims of study
We evaluated the prevalence of Lower Urinary Tract symptoms (LUTS) and the impact of LUTS on quality of life (QoL) in different genders using validated questionnaires as well as identifying the potential risk factors that were associated with the occurrence of LUTS in these community residents.
Study design, materials and methods
This study was carried out in three communities located in the west and south area of central Taiwan.  Community residents of both sexes, aged 40 years and above were invited to participate in this three-year study.  The residents who agreed to participate in this study were asked to fill in a set of validated questionnaires such as the IPSS and OABSS (Homma’s version) for subjective perception of LUTS, the UDI-6 and IIQ-7questionnaires for the impact of LUTS on QoL, and the SF-36 questionnaire for general health status.
Results
A total of 2,411 community residents aged 40 years and above who completed all the questionnaires in the initial survey were recruited, of which 1469(60.9%) were women and 942 (39.1%) were men. The percentage distributions of participants in different age cohorts (e.g. 40-49 years, 50-59 years etc.) were similar among both genders. Prevalence of stress urinary incontinence, urge urinary incontinence, mixed incontinence, overactive bladder, and voiding difficulty between female and male residents were significantly different (46.7% vs.2%; 26.8%vs. 16.1%; 21.2% vs. 1.2%; 33.1% vs. 26.5%; 28.3% vs. 39%; all P < 0.05) (Table 1). 
Prevalence of overactive bladder increased with age in both genders (P < 0.05) and was higher in women than men in each age cohort except those at ages ≧70 years (Table 2). 
Female residents with stress urinary incontinence, urge urinary incontinence, mixed urinary incontinence, overactive bladder and voiding difficulty had significantly lower scores in all eight domains of the SF-36 indicating poorer physical, mental, social health and functional status. However, male residents with urge urinary incontinence, overactive bladder and voiding difficulty were associated with a significantly lower score in all eight domains. 
For the female residents, age≧60 years, menopause and a history of diabetes mellitus were the risk factors for overactive bladder. Voiding difficulty was associated with age≧60 years, BMI ≧25 and instrument-assisted deliveries. For the male residents, age≧60 years and a history of diabetes mellitus were the risk factors for overactive bladder.  Age≧60 years, a history of diabetes mellitus, low educational level and a previous history of urolithiasis were the risk factors for voiding difficulty.
Interpretation of results
Our results imply that prevalence of stress urinary incontinence, urge urinary incontinence, mixed urinary incontinence, overactive bladder and voiding difficulty have significant gender diversity. Prevalence of overactive bladder increased with age in both genders (P < 0.05) but was higher in women than men in each age cohort. Age≧60 years was the common factor associated with the occurrence of overactive bladder and voiding difficulty.
Concluding message
In general, female residents with stress urinary incontinence, urge urinary incontinence, mixed incontinence, overactive bladder or voiding difficulty have significant score in domains of physical, mental, social health and functional status. Male residents with urge urinary incontinence, overactive bladder and voiding difficulty have significant lower score in all eight domains of general health status in SF-36 questionnaire.
