Prevalence of Epilepsy in People of Sexual and Gender Minoritized Groups.

Abstract

Epilepsy is a highly treatable condition for many people, but there are large treatment gaps with suboptimal seizure control in minoritized groups. The sexual and gender minority (SGM) community is at risk for health disparities, yet the burden of epilepsy in this community is not known. To estimate the prevalence of active epilepsy among SGM people in the United States. This was a cross-sectional, nationally representative survey study of community-dwelling US adults who answered questions about epilepsy, sexual orientation, and gender identity in the 2022 National Health Interview Survey (NHIS). Self-identification of transgender or gender-diverse identity, or sexual orientation including gay, lesbian, bisexual, or other orientation, excluding straight (ie, heterosexual). Participants self-reported epilepsy status, medical treatment, seizure frequency, demographic characteristics, sexual orientation, and gender identity. Logistic regression was used to estimate the association of epilepsy with SGM identification. A total of 27 624 participants (15 050 [54%] women; 3231 [12%] Black; mean [SD] age, 48.2 [18.5] years) completed the NHIS and were included. Active epilepsy was present in 1.2% (95% CI, 1.0%-1.3%) of the population. A higher proportion of SGM adults than non-SGM adults reported active epilepsy (2.4% [95% CI, 1.4%-3.3%] vs 1.1% [95% CI, 1.0%-1.3%], respectively). After adjusting for age, race, ethnicity, income, and education, SGM people were more than twice as likely to report active epilepsy than were non-SGM adults (adjusted odds ratio, 2.14; 95% CI, 1.35-3.37). The findings suggest that SGM adults in the United States have a disproportionate prevalence of epilepsy. The reasons for this disparity are likely complex and may be associated with biological and psychosocial determinants of health unique to this population; as such, these individuals are in need of protected access to medical care.
