Abstract

BackgroundThere 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.MethodsAn 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.ResultsOne 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.ConclusionLUTS prevalence and severity vary with age, but not with BMI, MAC or Wealth-Index.

Highlights

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
Though the prevalence of LUTS among men may vary from community to community [3, 4], the onset of these symptoms is usually insidious and the course usually progressive
There are indications as well that storage LUTS may be more prevalent than voiding LUTS and post-void LUTS [4]

Summary

Introduction

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. The prevalence of lower urinary tract symptoms (LUTS) increases with increasing age in men. The severity of these lower urinary tract symptoms tend to worsen over time from mild less bothersome symptoms to severe quite bothersome symptoms [5], though there may be intermittent remissions in symptoms of varying durations within this natural history of symptom progression. Hospital-based estimates of the prevalence of LUTS in southeast Nigeria, a higher low-income country, has been documented [7], but community-based prevalence of LUTS in the region is essentially lacking. There are indications as well that storage LUTS may be more prevalent than voiding LUTS and post-void LUTS [4]
