Disparities in Subjective Cognitive Impairment by Sexual Orientation and Gender in a National Population Based Study of U.S. Adults, 2013-2018.

Objectives

This is the first national population-based study to examine cognitive impairment disparities among sexual minority mid-life and older adults.

Methods

Using the National Health Interview Survey (2013-2018), we compared weighted prevalence of subjective cognitive impairment by sexual orientation and gender, among those aged 45 plus, applying logistic regressions adjusting for age, income, education, race/ethnicity, and survey years.

Results

Sexual minorities (24.5%) were more likely to have subjective cognitive impairment than heterosexuals (19.1%). Sexual minority women had higher odds of greater severity, frequency, and extent of subjective cognitive impairment. Sexual minorities were also more likely to report activity limitations resulting from cognitive impairment and were no more likely to attribute limitations to dementia or senility. Discussion: Cognitive health disparities are of particular concern in this historically and socially marginalized population. The investigation of explanatory factors is needed, and targeted interventions and policies are warranted to address cognitive challenges faced by sexual minorities.
