HIV knowledge and high-risk sexual behaviors of men who have sex with men in college students

Abstract

Objective To understand HIV knowledge and high-risk sexual behaviors among men who have sex with men (MSM) in the HIV-infected students’social network, and to provide a scentific reference of making targeted and effective measures.

Methods A mixed recruitment method of snowball sampling and respondent driven sampling was used to recruit HIV-infected students with the help of local CDC in Harbin, Tianjin, Xi’an and Chongqing, with demographic information, sexual behaviors and HIV knowledge collected via questionnaire survey.

Results A total of 549 valid questionnaires were analyzed. Among them, the awareness rate of “Guo Ba Tiao” was 90.7% and the awareness rate of “Qing Ba Tiao” was 89.4%, the consistent condom use rate was 59.4%. Among those who were aware of HIV, 40.8% exhibit the mismatch between HIV knowledge and condom use behavior, which was significantly associated with number and types of sex partners. Those who had 1-3 regular male sex partners (1 partner: a OR = 2.48, 95% CI =1.61-3.82; 2-3 partners: a OR = 2.45,95% CI = 1.44-4. 15), or 1-3 causal male sex partners (1 partner: a OR =1.74, 95% CI =1.10-2.77; 2-3 partners: a OR = 2.15, 95%CI =1.34-3.46) were more likely for this mismatch. Those who had more than one commercial male sex partner (aOR =3.35, 95% CI = 1.15 — 9.80), or more than one regular female sex partner (aOR = 2.49, 95% CI =1.17-5.28), or more than one casual female sex partner ( OR = 2.80, 95% CI =1.01-7.71), the risk for this mismatch was also high.

Conclusion The mismatch between HIV knowledge and condom use behavior among MSM students from the social network of young students living with HIV/AIDS is severe. It is necessary to carry out tailored HIV intervention to reduce the transmission of HIV among those people.

【摘要】目的 了解艾滋病感染者推介（社交网络中）的青年学生男男性行为MSM人群（men who have sex with men, MSM)髙危性行为和艾滋病知识现状，为针对该人群制定有效的干预措施提供科学依据。 方法在哈尔滨、天津、西安、重 庆4个城市，通过对学生艾滋病感染者发布招募信息，动员其主动预约参加调査，然后通过滚雪球抽样和受试者推荐的混 合抽样方法，对艾滋病感染青年学生社交圈中的学生MSM人群共549名进行横断面调査，收集一般人口学特征、髙危性行 为发生情况和艾滋病知识知晓情况。 结果青年学生的“中国艾滋病防治督导与评估指标体系”知晓率为90.7%，“中国 疾病预防控制中心关于印发艾滋病宣传教育核心知识与艾滋病知识的通知”知晓率为89.4%，安全套持续使用率为 59. 4%。在达到知晓水平的调査对象中，有40.8%出现艾滋病知识和坚持使用安全套行为的分离，且艾滋病知行分离与 HIV感染及不同的性伴类型与性伴数量均存在紧密相关，青年学生有1~3个固定男性伴（1个:aOfl = 2.48，95% CI =1.61~ 3.82； 2~3 个：aOfi = 2.45，95%CT= 1.44~4.15)，或 1~3 个临时男性伴（1 个：aOfi =1.74，95%CI = 1.10-2.77； 2~3 个:aOfi = 2.15，95%CI =1.34-3.46)时，出现知行分离的概率增加；有1个及以上的商业男性伴（aOfl =3.35，95% CI = 1.15 ~9.80)，或 1个及以上的固定女性伴（aOfl = 2.49，95%CI =1.17-5.28)，或1个及以上的临时女性伴（aOfl = 2.80，95%CI =1.01-7.71) 的青年学生也会出现知行分离（ P值均<0.05)。 结论艾滋病感染青年学生社交圈中的学生MSM人群艾滋病知识和安全 套坚持使用行为分离现象严峻，需要进一步提供针对性措施以降低HIV在该人群中的传播。
