Concurrent sexual relationships facilitate the spread of HIV infection, and sex with non-primary partners may pose particularly high risks for HIV transmission to primary partners.
We examined the sexual and alcohol-related risks associated with sex partners outside of primary relationships among South African men and women in informal drinking establishments.
Men (n=4959) and women (n=2367) with primary sex partners residing in a Xhosa-speaking South African township completed anonymous surveys. Logistic regressions tested associations between having outside partners and risks for sexually transmitted infections (STI)/HIV.
Forty-four percent of men and 26% women with primary sex partners reported also having outside sex partners in the previous month. Condom use with outside partners was inconsistent for men and women; only 19% of men and 12% of women used condoms consistently with outside sex partners. Multivariable regressions for men and women showed that having outside partners was significantly associated with having been diagnosed with an STI, consuming alcohol in greater frequency and quantity, alcohol use during sex, meeting sex partners in alcohol-serving venues, and higher rates of unprotected sex.
Having outside sex partners was associated with multiple risk factors for HIV infection among South African shebeen patrons. Social and structural interventions that encourage condom use are needed for men and women with outside partners who patronise alcohol-serving venues.
同时存在性伴侣会促进 HIV 感染的传播,与非主要性伴侣发生性行为可能会对 HIV 向主要性伴侣传播带来特别高的风险。
我们研究了南非非正式饮酒场所中,主要性伴侣关系之外的性伴侣和与酒精相关的风险,与男女参与者相关。
与主要性伴侣居住在科萨语区的南非男性(n=4959)和女性(n=2367)参与者完成匿名调查。逻辑回归检验了拥有外部伴侣与性传播感染(STI)/HIV 风险之间的关联。
44%的男性和 26%的女性与主要性伴侣报告在过去一个月内也有外部性伴侣。男性和女性与外部性伴侣使用安全套的情况不一致;只有 19%的男性和 12%的女性与外部性伴侣始终使用安全套。男性和女性的多变量回归显示,拥有外部伴侣与被诊断患有性传播感染、更频繁和大量饮酒、性行为中饮酒、在供应酒精的场所中认识性伴侣以及无保护性行为的比例更高有关。
在南非饮酒场所的常客中,拥有外部性伴侣与 HIV 感染的多个风险因素有关。需要针对有外部性伴侣且光顾供应酒精场所的男性和女性实施鼓励使用安全套的社会和结构性干预措施。
