Assessment of Female Sexual Dysfunction and Erectile Dysfunction and Its Association with Lower Urinary Tract Symptoms in Women and Men Over 18 Years Old: Results From the COBaLT Study

Abstract

Background: Female sexual dysfunction and erectile dysfunction (FSD/ED) have been linked with lower urinary tract symptoms (LUTS), from both epidemiological data and basic research studies, but few studies have been conducted in Latin America addressing these issues and most of them do not include the young population.

Aim: To determine the prevalence of FSD/ED and its association with LUTS in Colombia.

Methods: Sub-analysis of a cross-sectional, population-based study conducted in subjects ≥18 years old to evaluate LUTS/OAB. The estimated sample size was 1,054. ED was defined as ≤21 points in the SHIM and FSD as ≤19 in the FSFI-6. For LUTS/OAB, we used the 2002 ICS and 2010 IUGA/ICS definitions and validated questionnaires. Descriptive and inferential statistics were employed.

Outcomes: Prevalence of FSD/ED and association of FSD/ED and LUTS.

Results: We included 1,060 participants; the median age was 40 (IQR 27-54) years. Fifty-seven (11.4%) men and 182 (32.7%) women were sexually inactive. The prevalence of FSD/ED in sexually active participants was 47% (men 52.9%, women 38.9%). The most common FSD/ED symptoms were diminished/absent lubrication in women (42%) and diminished erection maintenance after penetration in men (13%). Individuals with FSD/ED had higher rates of various LUTS. The multivariable logistic regression model found that the city of residence (OR = 0.4, 95% CI 0.2-0.9), diabetes mellitus (DM) (OR = 8.4, 95% CI 1.4-48.7), menopause (OR=3.5, 95% CI 1.9-6.2), urge urinary incontinence (UUI) (OR=1.9, 95% CI 1.1-3.3) and nocturia ≥2 (OR = 2.2, 95% CI 1.2-4.2) were associated with FSD. In men, age 40-59 (OR = 2.3, 95% CI 1.4-3.7) and ≥60 (OR = 5.5, 95% CI 2.4-12.5), the city of residence (OR = 0.2, 95% CI 0.1-0.3), less than a high-school diploma vs higher education (OR = 2.0, 95% CI 1.2-3.2), depression (OR = 4.6, 95% CI 1.8-11.5), UUI (OR = 3.2, 95% CI 1.1-10.2) and feeling of incomplete bladder emptying (OR = 2.1, 95% CI 1.3-3.5) were associated with ED.

Clinical implications: This study underlines the importance of assessing LUTS in women and men of all affected age groups who present with symptoms of FSD/ED and vice versa, which could help achieve a better approach for these patients.

Strengths & limitations: This is the first study in Colombia and one of the few in Latin America that addresses both FSD/ED and LUTS in men and women aged 18 years and older. Limitations include being a sub-analysis of a study aiming to determine the prevalence of LUTS/OAB and not FSD/ED.

Conclusions: Regardless of age, LUTS were observed more frequently in patients with FSD/ED. Various LUTS were associated with FSD/ED. Bravo-Balado A, Trujillo CG, Caicedo JI, et al.
