Abstract

Background: There is paucity of information on the community-based prevalence and severity of lower urinary tract symptoms (LUTS) in men who are 40 years and older in the southeast region of Nigeria. This study seeks to determine the community-based prevalence of LUTS and the relationship between LUTS, and body mass index (BMI) and mid-abdominal circumference (MAC) in men.

Methods: An interviewer-administered, questionnaire-based survey. Three of nine settlement clusters were randomly selected while systematic random sampling of 1 in 3 eligible subjects was used to select participants. Analysis was done using SPSS® version 20.

Results: One thousand three hundred and nineteen duly completed questionnaires were analyzed. The respondents are within ages 40-92 years with mean age 54.2 ± 10.2 years, mean BMI 25.97 ± 4.18Kg/m2 and mean MAC 89.80 ± 12.43 cm. Overall prevalence of LUTS is 20.2%. Nocturia at a prevalence of 19.2% is the most prevalent lower urinary tract symptom and also the earliest to manifest. LUTS prevalence and severity increases with increasing age. About 9.6% report moderate LUTS while 2.3% report severe LUTS. Storage LUTS are reported more frequently than voiding LUTS. LUTS did not vary significantly with BMI, MAC or Wealth-Index.

Conclusion: LUTS prevalence and severity vary with age, but not with BMI, MAC or Wealth-Index.

Keywords: BMI; LUTS; Men; Mid-abdominal circumference.

A line chart showing the relationship between respondents’ age and the proportion of respondents experiencing at least one lower urinary tract symptom (N = 1319). This figure shows that there is a gradual increase in the prevalence of LUTS from 40 years of age. The increase is at the rate of 7% per decade from 40 to 70 years. Beyond 70 years of age the rate of increase is nearly tripled

A cluster bar chart showing severity of lower urinary tract symptoms within the various age categories of respondents with LUTS (N = 267) Before the age of 60 years, mild LUTS is more prevalent, while beyond the age of 70 years, moderate to severe LUTS become more prevalent. This pattern is significant statistically
