Branched sexuality and sexual health among Black cisgender sexual minority men in Baltimore, Maryland: an exploratory study.

Branched sexuality - in form of combinations of sexual identity, behaviour and attraction (e.g. heterosexual identity, sex with men, attraction to women) that differ from coincident combinations (e.g. gay/homosexual/same-gender-loving identity, sex with men, attraction to men) - has been observed among Black sexual minority men and may correlate with sexual health. Using baseline survey data from Black sexual minority men ( N  = 323) enrolled in a sexual health intervention trial, we examined sexual identity, behaviour and attraction to determine the prevalence of branched sexuality and used modified Poisson regression with robust variance estimation to test associations with sexual health. Black sexual minority men reporting branched sexuality ( n  = 50, 15.5%) were marginally more likely to endorse negative condom-use attitudes compared to those reporting coincident sexuality ( n  = 273, 84.5%; adjusted prevalence ratio [aPR] = 1.48, 95% confidence interval [CI] = 0.94, 2.32) and significantly more likely to endorse negative condom-use attitudes compared to those reporting gay/homosexual/same-gender-loving-coincident sexuality (aPR = 1.85, 95% CI = 01.07, 3.22). Those reporting branched sexuality were significantly less likely to report past-year testing for sexually transmitted infections compared to those reporting coincident (PR = 0.52, 95% CI = 0.28, 0.94) or gay/homosexual/same-gender-loving-coincident sexuality (PR = 0.46, 95% CI = 0.25, 0.84) in bivariate analyses only. Increased understanding of Black sexual minority men's sexuality and improved sexuality data collection efforts are needed.
