Aging in isolation: Sexual orientation differences in navigating cognitive decline

Abstract

IntroductionSubjective cognitive decline is a self-reported measure of worsening memory and day-to-day decision making. Cognitive decline may impair an individual's ability to complete instrumental activities of daily living (IADL) such as preparing meals or taking medication, ultimately limiting one's ability to live independently. People with IADL impairments typically rely on informal care from spouses or children. Interpersonal and structural discrimination towards sexual minority (SM, including lesbian, gay, bisexual, and other queer identified) populations may contribute to disparities in cognitive decline and informal care outcomes. ObjectiveEstimate differences in prevalence, severity, and receipt of social support for subjective cognitive decline stratified by sex and SM status. MethodsCross-sectional study design using a probability sample (n = 172,047) from the Behavioral Risk Factor Surveillance System 2015–2019. Prevalence estimates and multivariable Poisson regression models were used to compare outcomes by sex and sexual identity. ResultsCompared to heterosexual peers, SM men and women were more likely to experience cognitive decline (15% of SM men, 11% of heterosexual men, 17% of SM women, 11% of heterosexual women). In adjusted models, SM women were 22% more likely (95%CI:3%–44%, p < .05) to report IADL impairments due to cognitive decline but were 17% less likely (95%CI:1%–31%, p < .05) to receive any social support with IADL impairments compared to heterosexual women. In adjusted models, SM men were 25% more likely (95%CI: 0%–56%, p < .05) to report IADL impairments due to cognitive decline but reported no significant difference in receiving social support with IADL impairments compared to heterosexual men. DiscussionWe identified significant unmet need for social supports for IADL impairments, with highest unmet need among SM women. Comprehensive strategies such as LGBTQ + affirming assisted living and home and community-based services are needed to ensure equity in receipt of long-term supports and services for SM populations.
