Premature Ejaculation: Prevalence and Relationship with Body Mass Index

Le résumé fourni par la source

Introduction: Premature ejaculation is one of the major disorders of sexual functions in males. The prevalence rate of 25-40% has been reported across all age groups globally. Ejaculation latency is affected by psychosomatic factors which may include obesity but the relationship between PE and obesity have not been well documented in sub-Saharan Africa. This study evaluates the prevalence of PE and correlation between PE and body mass index. Methods: This is a prospective cross-sectional study carried out in Federal Capital Territory (FCT) Abuja, Nigeria over a period of 2 years from January 2019 to December 2020. By simple random sampling, participants were recruited for the study. Two questionnaires (a proforma and PEDT) were administered to all the participants who gave consent to be enrolled and met the inclusion criteria. Two basic anthropometric measurements (weight and height) were objectively obtained. Data obtained were analyzed using Statistical Package for Social Sciences version 20.0. P value of less than 0.05 was considered statistically significant. Results: A total of 426 persons participated in the study. Majority of the participants (51.88%) fell within the age range of 20-30 years, while seventy-five participants (17.61%) were between the age ranges of 31-40 years. Those that fell within the age range of 41-50, 51-60, and 61-70 years were 16.43%, 8.22% and 5.87% respectively. Seventy-two participants (16.9%) had PE while three hundred and six participants (71.83%) had no PE. Probable/borderline PE was noted in 48 (11.27%) participants. Mean age of participants with PE was 27.88 years while the mean age of participants with borderline PE was 25.67 years. Mean age of participants with no PE was 41.85 years. Sixty-seven participants (15.73%) were obese, 131 (30.75%) were overweight while 228 (53.52%) had normal BMI. Amongst the participants who had PE, 48 (66.67%) had normal BMI, 16 (22.22%) were overweight while 8 (11.11%) were obese. Majority of participants (66.67%) with probable/borderline PE had normal BMI, 16.67% were overweight while 16.67% were obese. P value of less than 0.05 was significant. Conclusion: This study shows that premature ejaculation is common amongst all age group and has a variable relationship with body habitus, possibly dependent on the sub-type of premature ejaculation. There was an inverse correlation between PE and BMI in younger populations which suggests a lifelong sub-type. PE was also commoner in leaner younger participants and the number of participants with PE decreased as BMI increased.
