Concordance of high blood pressure among middle-aged and older same-sex couples in the USA.

ABSTRACT

Heterosexual couples in romantic relationships are known to influence each other's hypertension risk. However, the role of partners on an individual's hypertension status in same-sex relationships is less understood. Our objective is to characterize the burden of high blood pressure among middle-aged and older couples consisting of men who have sex with men (MSM) and women who have sex with women (WSW) living in the US. Among 81 same-sex couples from the Health and Retirement Study 2006-18, 72.4% (95%CI 23.4-95.7) MSM couples and 61.0% (95%CI 30.4-84.8) WSW couples consisted of both partners with hypertension. Same-sex couples demonstrate high concordance of hypertension and related risk factors, suggesting a need to develop novel interventions targeting MSM and WSW couples.
