目的 了解昆明市通过社会组织新报告HIV感染的MSM的流行病学特征及梅毒感染情况,为进一步制定更有针对性的防控策略和干预措施提供依据.方法 2018年1月至2019年12月在昆明市通过社会组织收集新报告HIV感染MSM的行为特征、实验室检测和梅毒感染情况,并进行分析.结果 共计纳入研究对象280名,年龄21~30岁占55.0%(154/280),大专及以上文化程度占66.4% (186/280),未婚人数占84.6%(237/280).实验室检测结果显示,CD4细胞计数小于200个/μL的研究对象占15.0% (37/247),病毒载量在104~105 copies/mL之间占48.9%(132/270).梅毒抗体阳性率为21.1%(59/280),多因素Logistics回归分析提示既往有性病史是梅毒感染的危险因素.结论 昆明市通过社会组织新发现HIV感染MSM中梅毒阳性率较高,且既往有性病史是梅毒感染的危险因素.需要采取有效措施落实MSM的HIV防控策略和干预手段,并且控制梅毒在该人群中的传播.

目的 评价“心理-行为-社会”综合干预模式对重庆市新确证HIV阳性的MSM的干预效果.方法 采取对照试验研究方法,按照研究对象HIV初筛阳性时顺序,分干预组和对照组.干预组采取“心理-行为-社会”综合干预模式,在对照组的基础上开展心理干预、行为干预和社会支持.对照组按照国家要求开展常规的阳性告知和每6个月一次的随访.在干预前、干预后分别对干预组和对照组共做2次问卷调查.数据核对后,通过SPSS18.0软件对数据进行统计分析,评估干预措施效果.结果 共完成干预组和对照组各50人的干预前后问卷调查及干预活动.
