青少年男男性行为人群性感觉寻求水平与首次同性性行为研究

目的 研究青少年男男性行为人群（young men who have sex with men，YMSM）性感觉寻求水平与首次同性性行为状况的关系。方法 通过互联网宣传、外展活动以及例行的艾滋病自愿检测服务，招募YMSM作为调查对象进行匿名问卷调查。结果 调查的375名YMSM首次同性性行为年龄为（18.98±2.11）岁，83.38%报告为双方自愿，61.93%的性伴年龄比调查对象大，50.94%在首次同性性行为时使用安全套，35.12%的性伴为朋友。性感觉寻求水平与首次同性性行为年龄及安全套使用状况均呈负相关（偏相关系数分别为-0.171和-0.248）。多因素分析结果显示，性感觉寻求得分每增加1分，首次同性性行为年龄由20岁以上降至18~20岁及18岁以下的可能性分别增加0.065倍和0.109倍（OR=1.065，95%CI：1.016~1.117；OR=1.109，95%CI：1.046~1.175），且首次同性性行为不使用安全套的可能性增加0.070倍（OR=1.070，95%CI：1.034~1.107）。性感觉寻求水平越低者，越倾向于与朋友发生首次同性性行为，而非偶遇性伴（OR=0.936，95%CI：0.900~0.974）。结论 性感觉寻求水平越高者首次同性性行为年龄越小、越倾向于选择偶遇性伴，且在首次同性性行为时不使用安全套。

Relationship between sexual sensation seeking and the situation of having sex with men for the first time among young men who have sex with men

Objective To explore the association between sexual sensation seeking and the situation of having sex with men for the first time among young men who have sex with men (YMSM). Methods YMSM were recruited through online publicity, organization of outreach activities together with HIV voluntary testing services. And they were investigated via anonymous questionnaires. Results A total number of 375 valid questionnaires were received.The first gay sex age was (18.98±2.11), 83.38% happened by mutual consent, 61.93% had sex with man who was older, 50.94% used condoms for the first time, 35.12% chose friend as the first sexual partner. Results from partial correlation analysis showed that sexual sensation seeking was negatively correlated with the first gay sex age and condoms using (r=-0.171 and -0.248,respectively). The multinomial logistic regression results showed that every point increasing of sexual sensation seeking score indicated that the possibility of the first gay sex age dropped from 20 and above to 18~20 and less than 18 increased 0.065-fold and 0.109-fold respectively (OR=1.065,95% CI:1.016-1.117; OR=1.109,95%CI:1.046-1.175). And the possibility of the first gay sex without using condoms increased 0.070-fold (OR=1.070, 95% CI:1.034-1.107). On the contrary, those who owned lower sexual sensation seeking score tended to choose friends rather than encounter sexual partners when having sex with men for the first time (OR=0.936, 95% CI:0.900-0.974). Conclusions YMSM who owned higher sexual sensation seeking score were younger and tended to choose encounter sexual partners when having sex with men for the first time. They were also more likely to have sex for the first time without using condoms.
