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 ( = 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 ( = 50, 15.5%) were marginally more likely to endorse negative condom-use attitudes compared to those reporting coincident sexuality ( = 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.
分支性取向——以性认同、行为和吸引力的组合形式存在（例如异性恋认同、与男性发生性行为、对女性有吸引力），与一致的组合形式（例如同性恋/同性爱认同、与男性发生性行为、对男性有吸引力）不同——在黑人少数性取向男性中已经观察到，并且可能与性健康相关。我们使用参加性健康干预试验的黑人少数性取向男性（n=323）的基线调查数据，检查了性认同、行为和吸引力，以确定分支性取向的流行率，并使用修正的泊松回归和稳健方差估计来检验与性健康的关联。与报告一致性取向（n=273，84.5%）的男性相比，报告分支性取向（n=50，15.5%）的黑人少数性取向男性更有可能对负面的 condom 使用态度表示认可（调整后的患病率比[aPR]=1.48，95%置信区间[CI]=0.94，2.32），并且与报告同性恋/同性爱一致性取向的男性相比，更有可能对负面的 condom 使用态度表示认可（aPR=1.85，95% CI=01.07，3.22）。与报告一致性取向的男性相比，报告分支性取向的男性过去一年进行性传播感染检测的可能性显著较低（PR=0.52，95% CI=0.28，0.94）或报告同性恋/同性爱一致性取向的男性（PR=0.46，95% CI=0.25，0.84），仅在二项分析中。需要进一步了解黑人少数性取向男性的性取向，并改善性数据收集工作。
