Abstract

Background: Hypertension is a leading risk factor for cardiovascular disease. Self-measured blood pressure (SMBP) monitoring has been identified as an effective strategy to achieve BP control among adults with hypertension. Although there is growing evidence that sexual minority (e.g., gay/lesbian, bisexual) adults are at higher risk of hypertension than heterosexual adults, there is no data on hypertension self-management among sexual minority people with hypertension. Methods: We used data from the 2019 Behavioral Risk Factor Surveillance System to examine differences in SMBP monitoring between sexual minority and heterosexual participants with hypertension. Participants were asked questions regarding SMBP monitoring at home, including whether they were advised by a healthcare professional to check their BP at home, regularly checked their BP at home, and if they shared their home BP readings with a healthcare professional. We ran sex-stratified logistic regression models, adjusted for demographic factors and healthcare utilization, to estimate differences in SMBP monitoring between sexual minority and heterosexual participants. Results: The sample included 25,461 participants with a mean age of 54.1 ( ± 16.8) of which 95.1% were heterosexual, 1.7% were gay/lesbian, and 2.2% were bisexual. Although there were no differences in the odds of being advised by a healthcare professional to check their BP at home, lesbian women were more likely than heterosexual women to report taking their BP at home (AOR 1.23, 95% CI = 1.03-4.85) and sharing their home BP readings with a healthcare professional (AOR 2.31, 95% CI = 1.04-5.17). In contrast, bisexual women were less likely than heterosexual women to report taking their BP at home (AOR 0.59, 95% CI = 0.43-0.81) and sharing their home BP readings with a healthcare professional (AOR 0.56, 95% CI = 0.40-0.78). No differences in SMBP monitoring were found between sexual minority and heterosexual men. Conclusions: As the first examination of sexual identity differences in SMBP monitoring among adults with hypertension, this study addresses important knowledge gaps within cardiovascular and sexual minority health research. Lesbian women with hypertension exhibited more favorable self-management behaviors compared to heterosexual women. However, bisexual women with hypertension were less likely than heterosexual women to engage in SMBP monitoring. Findings suggest there is a need for clinical interventions to improve hypertension self-management among bisexual women.
