African, Caribbean, and Black men constitute the second-highest category of males living with HIV in Ontario, which increased from 15.4% to 17% between 2011 and 2016. Previous studies have attributed this disproportionately higher rate to multiple concurrent sexual partnerships and low rates of HIV testing. Drawing on theoretical constructs of the health belief model (HBM), this study examined the relationship between multiple concurrent sexual partnerships and the uptake of HIV testing services among heterosexual Black men in Ontario.
Using a cross-sectional sample data of 829 individuals from four cities in Ontario, we employed the multinomial logit analysis to examine the relationship between multiple sexual partnerships and the uptake of HIV testing services among heterosexual Black men.
The findings show that heterosexual Black men with multiple concurrent sexual partners were more than twice (RRR = 2.306, < 0.01) as likely to test for HIV within the past 12 months when compared to those with one partner. Furthermore, being an immigrant, having good knowledge of HIV transmission, and earning lower annual income predicted higher odds of testing while sexual debut between the ages of 16 and 20 years, no visit to a healthcare provider in the past year and difficulty accessing healthcare significantly predicted lower likelihood of testing for HIV.
These findings align with the theoretical constructs of the health belief model but more importantly, they suggest heterosexual Black men with concurrent sexual partners may be aware of their HIV risk and are taking measures to know their serostatus. Hence, making HIV screening services accessible and at safer spaces could increase their use of HIV screening services.
在安大略省，非裔、加勒比裔和黑人男性是感染 HIV 的男性中第二大群体，其比例从 2011 年到 2016 年从 15.4%增加到 17%。先前的研究将这一不成比例的高比率归因于多重性伴关系和低艾滋病毒检测率。本研究借鉴健康信念模型（HBM）的理论结构，研究了安大略省异性恋黑人男性的多重性伴关系与艾滋病毒检测服务的采用之间的关系。
本研究使用安大略省四个城市的 829 名个体的横截面样本数据，采用多项逻辑回归分析，研究了异性恋黑人男性的多重性伴关系与艾滋病毒检测服务的采用之间的关系。
研究结果表明，与只有一个性伴的异性恋黑人男性相比，有多个同时性伴的异性恋黑人男性在过去 12 个月内进行艾滋病毒检测的可能性高出两倍多（RRR = 2.306， < 0.01）。此外，作为移民、对艾滋病毒传播有较好的了解以及收入较低与更高的检测几率相关，而在 16 至 20 岁之间首次发生性行为、过去一年未就诊于医疗保健提供者以及难以获得医疗保健与较低的检测几率显著相关。
这些发现与健康信念模型的理论结构一致，但更重要的是，它们表明同时有多个性伴的异性恋黑人男性可能意识到自己的艾滋病毒风险，并正在采取措施了解自己的血清状况。因此，使艾滋病毒筛查服务更容易获得并在更安全的场所提供，可以增加他们对艾滋病毒筛查服务的使用。
