A Meta-Analysis of Blood Pressure Disparities Among Sexual Minority Men

The aim was to review and summarize reports on three measures of elevated blood pressure (BP) among sexual minority men (encompassing men who have sex with men [MSM] and both men and women [MSMW]), using men who have sex with women (MSW) as the reference population. Crude prevalence rates were calculated, and a meta-analysis was conducted to summarize the likelihood of elevated BP history, antihypertensive medication use, and elevated BP above a cutoff value, as well as the mean differences (MDs) in systolic BP (SBP) and diastolic BP (DBP) measurements. We used random effects to generate estimates with their respective 95% confidence intervals (CIs); alpha was set at 0.05. Studies (n = 20) were published between 2007 and 2018, mostly in the United States. The likelihood of elevated BP history was not statistically significantly higher among sexual minority men, except when the measurement of sexual orientation was multidimensional (odds ratio [OR] 1.41, 95% CI 1.12-1.78). The likelihood of antihypertensive medication use was only statistically significantly higher for men who self-identified as MSMW (OR 1.44, 95% CI 1.11-1.85). When elevated BP was determined through a set cutoff, MSM were less likely (OR 0.34, 95% CI 0.16-0.70), whereas MSMW were more likely (OR 2.25, 95% CI 1.54-3.28) to have elevated BP. Although there were no statistically significant findings in the MD for SBP, the MD for DBP among sexual minority men was significantly higher (MD 1.46, 95% CI 1.38-1.55 mmHg) than among the MSW comparison group. Sexual minority men classified using a multidimensional approach to sexual orientation had a significantly higher likelihood of elevated BP history. Using BP cutoffs yielded opposite effects in MSM and MSMW. Although SBP was not different compared to MSW, DBP-a marker of hypertension at earlier ages-was elevated among sexual minority men.
