Objective: To determine the age-specific prevalence, severity of LUTS and the commonest risk factor among Nigerian patients.
Methods: A prospective, non-randomized study of 360 men was carried out at the Ekiti State University Teaching Hospital, Ado-Ekiti, south- western Nigeria between 1st of January, 2012 and 31st of December, 2014. The International Prostate Symptoms Score (IPSS) questionnaire was used for the assessment of LUTS and quality of life [QoL].
Results: The mean age of the study population was 64±12.8 years and men in the age group 60-69 years had the highest prevalence of 27.8%. Eighty-two and half percent [82.5%] of the men had moderate to severe symptoms (IPSS score > 7). The prevalence of storage symptoms was significantly higher than that of voiding symptoms in all age groups. LUTS was not associated with smoking or body mass index, p>.05. Men with diabetes had odd ratio of 1.640[95%CI=0.895-3.005] and hypertension 1.071 [95%CI=0.773-1.484] higher than those without two diseases and also poorer QoL. Known alcoholic patients were less likely to develop LUTS and poor QoL than non alcoholics, odd ratio [OR] was 0.774[95%CI=0.573-1.047]. The age of patient was also significantly associated with good QoL with patients aged >65 years having good QoL compared to those aged<65years (p<0.05). The OR for developing poor QoL for patients aged˂65years was 1.331[95%CI=1.063-3.543] while for aged>65 years, it was 0.686[95%CI=0.470-1.001].
Conclusion: LUTS was commonest in the 7th decade of life and alcohol consumption was the commonest but protective risk factor in south -western Nigeria. Majority of the patients presented with moderate to severe symptoms.
