目的分析南京市2012年新报告HIV抗体阳性病例的流行病学特征。方法采用Excel数据库和SPSS 13.0统计软件对南京市2012年在国家艾滋病防治信息系统中报告的543例病例资料进行整理和分析。结果新报告的543例研究对象中,男性占91.53%,平均年龄(37.01±12.44)岁,本市籍占47.88%。感染途径以性途径为主,占93.01%。职业分布以商业服务(25.41%)、家政家务或待业(23.03%)为主,学生病例占6.6%。样本来源以医疗机构(54.41%)和自愿咨询检测门诊(voluntary counseling and testing,VCT)(20.41%)为主。43.24%的HIV抗体阳性病例CD4+T淋巴细胞计数<350个/μl。单因素分析显示,不同传播途径、婚姻状况、职业以及文化程度与新发现HIV抗体阳性病例病程阶段均有关(P<0.05)。结论今后南京市应进一步加大MSM、学生和50岁以上等重点人群的艾滋病控制力度;并通过充分利用社会组织动员检测,全面推进医疗机构PITC(provider initiated HIV testing and counseling,PITC)服务等,扩大检测覆盖面,提高病例早发现能力。

The samples were mainly from medical institutions (54.41%) and voluntary counseling and testing (VCT) (20.41%). 43.24% of HIV-positive cases had CD4 + T lymphocyte counts <350 / μl. Univariate analysis showed that different routes of transmission, marital status, occupation and education level were related to the course of the newly discovered HIV antibody positive cases (P <0.05).
