Sexual identity differences in ideal cardiovascular health among cisgender adults in the All of Us Research Program

Cardiovascular health (CVH) disparities have been documented among sexual minority adults, yet prior research has focused on individual CVH metrics. We sought to examine sexual identity differences in CVH using the American Heart Association's composite measure of ideal CVH, which provides a more comprehensive assessment of future CVD risk.

Data from the All of Us Research Program were analyzed. Sexual identity was categorized as heterosexual, gay/lesbian, bisexual, or other. Individual CVH health metrics and cumulative ideal CVH (range 0-100) were assessed. We ran sex-stratified multiple linear regression models to estimate differences across individual CVH metrics and cumulative ideal CVH between sexual minority and heterosexual adults. We also explored differences in CVH across racial/ethnic and age groups.

The sample included 11 047 cisgender adults with a mean age of 61.1 years (± 13.85); 80% were non-Hispanic White. Lesbian women, gay men, and bisexual women reported greater nicotine exposure than their heterosexual counterparts. Compared to heterosexual men, gay men (B [95% CI] = -8.95 [-14.50, -3.39]) had worse physical activity scores. Gay men also had better body mass index scores than heterosexual men (B [95% CI] = 3.21 [0.09, 6.33]). Bisexual women and men had lower cumulative ideal CVH scores than heterosexual adults. Exploratory analyses revealed several differences in individual CVH metrics and cumulative ideal CVH across racial/ethnic and age groups.

Clinical interventions to improve the CVH of bisexual adults are needed. Findings can inform the design of interventions that are tailored for specific subgroups of sexual minority adults.
