Little research has evaluated the social and sexual network-related health outcomes of young black transgender women (TGW) or compared these outcomes with those of black men who have sex with men (MSM). Social network analysis offers one potent means of understanding the dynamics driving the broad spectrum of adverse outcomes experienced by these subgroups. We examined the social and sexual health network traits of 618 black individuals assigned male at birth who have sex with men, 47 (7.6%) of whom identified as TGW. Using respondent-driven sampling, data collection occurred over three waves between 2013 and 2016, in Chicago, Illinois. Univariate, logistic regression, and confidant and sexual network analyses were conducted to characterize dynamic network features. TGW's mean age was 22.1 (standard deviation ±2.6). TGW's sexual networks were significantly less stable (stability ratio of 0.175 vs. 0.278 among MSM, =0.03) and had greater network turnover (turnover ratio of 0.825 vs. 0.735, =0.04). TGW also had significantly more sex partners (7.6 vs. 4.0, =0.0002) and exchange sex (odds ratio=2.97; 95% confidence interval: 1.66-5.32, <0.001), lower rates of employment (39.6% vs. 71.1%, <0.001), and more reported an income <$20,000 (93.5% vs. 80.8%, =0.029). Within confidant networks, TGW had a borderline significantly higher network turnover ratio (0.703 vs. 0.625, =0.06). Furthermore, both TGW and MSM had high, but similar, HIV rates (42.3% vs. 30.6%, respectively; =0.17). There were no significant structural network differences vis-à-vis mean degree (=0.46), betweenness centrality (=0.40), closeness centrality (=0.18), or average shortest path length (borderline statistically significant at =0.06). Using data from a representative sample of younger black individuals, we observed black TGW have less sexual network stability in contrast to black MSM but comparable structural network features. We further observed that both groups, and black TGW especially, possess considerable system-level, socioeconomic, and sexual health burdens.
很少有研究评估年轻黑人跨性别女性(TGW)与社会和性网络相关的健康结果,或将这些结果与男男性行为者(MSM)的结果进行比较。社会网络分析提供了一种有效的手段,来理解驱动这些亚群体经历广泛不良后果的动态因素。我们研究了618名出生时被认定为男性的男男性行为黑人个体的社会和性健康网络特征,其中47人(7.6%)认定自己为TGW。利用应答驱动抽样方法,于2013年至2016年期间在伊利诺伊州芝加哥分三个阶段收集数据。进行了单变量分析、逻辑回归分析以及密友和性网络分析,以描述动态网络特征。TGW的平均年龄为22.1岁(标准差±2.6)。TGW的性网络稳定性显著较低(稳定性比率为0.175,而MSM为0.278,P = 0.03),且网络更替率更高(更替率为0.825,而MSM为0.735,P = 0.04)。TGW的性伴侣也显著更多(分别为7.6个和4.0个,P = 0.0002)且存在性交易(优势比 = 2.97;95%置信区间:1.66 - 5.32,P < 0.001),就业率较低(分别为39.6%和71.1%,P < 0.001),更多人报告收入低于20,000美元(分别为93.5%和80.8%,P = 0.029)。在密友网络中,TGW的网络更替率略高(0.703和0.625,P = 0.06)。此外,TGW和MSM的艾滋病毒感染率都很高,但相近(分别为42.3%和30.6%;P = 0.17)。在平均度数(P = 0.46)、中间中心性(P = 0.40)、接近中心性(P = 0.18)或平均最短路径长度方面(P = 0.06时具有边缘统计学显著性),没有显著的结构网络差异。利用来自年轻黑人个体代表性样本的数据,我们观察到与黑人MSM相比,黑人TGW的性网络稳定性较低,但结构网络特征相当。我们还进一步观察到,这两个群体,尤其是黑人TGW,都承受着相当大的系统层面、社会经济和性健康负担。
