摘要:
目的 分析广州市男男性行为人群(men who have sex with men,MSM)性感觉寻求与高危性行为的关联。 方法 2017年6月-2018年4月,通过智同公益服务中心友同门诊招募年龄18岁及以上的MSM。采用自行设计的电子问卷收集一般人口学特征、性行为特征、高危性行为和性感觉寻求等信息。采用非条件Logistic回归分析多性伴、一夜情和无保护肛交与性感觉寻求的关联。 结果 500名调查对象平均年龄(27.77±5.96)岁。调整了一般人口学特征与性行为特征后,多因素Logistic回归分析结果显示高性感觉寻求得分的MSM发生多性伴(OR=2.05,95%CI:1.40~2.30,P < 0.001),一夜情(OR=2.11,95%CI:1.44~3.09,P < 0.001)和无保护肛交(OR=1.70,95%CI:1.16~2.50,P=0.007)的风险高于低性感觉寻求者。 结论 广州市MSM高性感觉寻求者更可能发生高危性行为,在制定行为干预措施时应该考虑性感觉寻求的影响,以提高艾滋病干预的效果。 Abstract:Objective To evaluate the association between sexual sensation seeking (SSS) and sexual risk behaviors among men who have sex with men (MSM) in Guangzhou. Methods MSM aged 18 and over were recruited in Zhitong Charity from June 2017 to April 2018. Data on socio-demographic characteristics, sexual behaviors and SSS were collected using an electronic questionnaire. Logistic regression analyses were performed to evaluate the association between SSS and sexual risk behaviors. Results A total of 500 MSM were included in the current study. The mean age of the participants was (27.77±5.96) years old. The multiple logistic regression analyses showed that MSM with high SSS scores were more likely to engage in multiple sexual partners (OR=2.05, 95% CI: 1.40-2.30, P < 0.001), one-night stand (OR=2.11, 95% CI: 1.44-3.09, P < 0.001), and unprotected anal intercourse (OR=1.70, 95% CI: 1.16-2.50, P=0.007) than those with low SSS scores. Conclusions High SSS is associated with an increased risk of sexual risk behavior among MSM in Guangzhou. The behavior intervention strategy should be tailored for MSM with high SSS to improve the effectiveness to reduce sexual risk behaviors. -
