Objective.
Lower urinary tract symptoms (LUTS) in men are often associated with discomfort and restriction of social activity. We wanted to estimate the prevalence of LUTS by severity (using the International Prostate Symptom Score, IPSS), and to assess the association between putative risk factors and the presence of LUTS.
Subjects and Methods.
Between 1995 and 1997, LUTS data were collected from 21,694 male residents aged = 20 years in Nord-Trøndelag County in Norway, using the IPSS. Using the IPSS scale (range 0-35), LUTS was defined as a score of = 8, indicating moderate to severe symptoms. We estimated the prevalence of LUTS, and used logistic regression analysis to study lifestyle and anthropometric factors, and co-morbidity related to LUTS.
Results.
The overall prevalence of moderate to severe LUTS was 15.8% (13.2% moderate, and 2.6% severe symptoms). The prevalence of LUTS increased strongly with age, from ˜ 5% among men aged 30% when aged = 70 years. Factors positively associated with an increased risk of moderate and severe LUTS were anthropometric (body mass index and waist hip ratio) and lifestyle factors (alcohol consumption and smoking), as well as co-morbid conditions including diabetes, history of stroke, muscle complaints, and osteoarthritis.
Conclusion.
Although LUTS may be viewed as an inevitable consequence of the ageing process, it appears to be exacerbated by lifestyle factors and co-morbid conditions. This study confirms that the prevalence of LUTS among men increases strongly with age. Management of LUTS represents a big challenge to the general practitioner.
