Racial and Ethnic Differences in the Severity of Sexual Dysfunction Symptoms in Patients with Multiple Sclerosis

Sexual dysfunction (SD) is a common symptom for many with multiple sclerosis (MS). However, most studies researching this topic have predominantly White samples. While this matches epidemiological estimates, research has shown that those of other ethnic groups, such as African Americans/Blacks and Hispanics/Latinos, tend to exhibit more symptomology. This study aimed to determine if this greater symptomology in other ethnic groups with MS holds for SD. Study participants were recruited from the North American Research Committee on Multiple Sclerosis (NARCOMS) Registry. Participants completed the MSISQ-19 and the PDDS and provided demographic information. Study participants were 5445 respondents (Mage = 51 years, SD = 9.56, 75% female, 93% White). White, African American/Black, and Hispanic/Latino groups were compared on sexual dysfunction. Linear mixed effects modeling revealed that the MSISQ-19 subscale scores were significantly different for the African American/Black group (t =  − 2.48, p < 0.013) and all female participants (t =  − 2.58, p < 0.010). African American/Black participants had the least amount of primary SD (M = 10.56, 95% CI [9.09, 12.03]). African American/Black participants had the highest amount of secondary SD (M = 18.62, 95% CI [17.15, 20.09]), though the result was not statistically significant. Additionally, African American/Black females scored higher in all subscale scores when compared to African American/Black males, with a 3-point and 2-point difference in primary and tertiary symptoms. Our study has highlighted the importance of clinicians assessing for SD within their patients and to consider potential differences in symptom presentations of racial groups.
