Abstract
Introduction
A growing body of research has demonstrated extensive mental health disparities affecting sexual minority populations, yet little research has assessed how these disparities may affect cognitive functioning among subgroups of sexual minorities.
Methods
Data come from the 2021 National Health Information Survey (NHIS). Survey-weighted linear regression analyses were used to assess self-reported measures of cognition, stratified by subgroups sexual identity. In particular, we focused on the association between symptoms of depression or anxiety and each of the measures of cognition, adjusting for demographic covariates.
Results
Among 31,994 NHIS participants in the 2021 survey, 5,658 (17.7%) reported at least some difficulty in remembering or concentrating. Basic demographic differences existed when assessing any cognitive difficulty, particularly for bisexual participants (aOR = 2.73; 95% CI: 2.07, 3.60) and participants identifying as a different identity (aOR = 4.22; 95% CI: 2.72, 6.56). Depression was significantly associated with cognitive difficulty with the largest relationship observed among gay/lesbian participants (aOR = 1.39; 95% CI: 1.29, 1.49). The association between anxiety and cognitive difficulty was smallest among bisexuals (aOR = 1.13; 95% CI: 1.08, 1.18) and relatively consistent across other subgroups: heterosexuals (aOR = 1.23; 95% CI: 1.22, 1.24), gay/lesbians (aOR = 1.27; 95% CI: 1.19, 1.36), and those with a different identity (aOR = 1.22; 95% CI: 1.10, 1.35).
Conclusion
There is a clear set of health disparities between sexual minority subgroups and heterosexuals across all cognitive difficulties. Future research should focus on developing a better understanding of differences in cognition based on sexual minority status while also working to ascertain how disparities vary among sexual minorities.
