摘要目的 了解2015-2017年杭州市经非婚非商业异性性传播的新报告HIV感染者特征及其相关因素.方法 利用我国艾滋病综合防治基本信息系统,研究对象为2015年1月1日至2017年12月31日新报告HIV感染者,且现住址为杭州市、传播途径为非婚异性性传播.采用SPSS.20软件统计分析,比较不同特征的感染者经非婚异性性传播的比例,采用多因素logistic回归模型分析非婚非商业异性性传播感染HIV的相关因素.结果 新报告HIV感染者中的非婚异性性传播占38.03％(1 393/3 663),其中,非商业性传播占非婚异性性传播的50.83％(708/1 393),商业性传播占非婚异性性传播的49.17％(685/1 393).男女性别比为3.51∶1(1 084/309).男性以非婚商业性传播为主(61.81％,670/1 084),女性以非婚非商业性传播为主(95.1％,294/309).多因素分析结果显示,非婚非商业异性传播的相关影响因素包括女性(aOR=48.25,95％CI:26.94～88.44)、年龄＜30岁组(aOR=2.43,95％CI:1.31～4.51)、30～岁组(aOR=1.92,95％CI:1.11～3.33)、40～岁组(aOR=1.80,95％CI:1.08～3.00)、已婚和未婚(与离异或丧偶相比,aOR=1.57,95％CI:1.10～ 2.24;aOR=1.78,95％CI:1.15～2.78)、高中及以上文化程度(与小学及以下相比,aOR=1.82,95％CI:1.18～2.80)、职业为干部/职员(与农民相比,aOR=2.03,95％CI:1.04～ 1.91)、非婚性伴数＜5个(与非婚性伴数≥5个相比,aOR=10.65,95％CI:6.41～17.42).结论 2015-2017年杭州市非婚异性性传播HIV感染者比例高,不同性别、年龄、婚姻状况、文化程度和职业的HIV感染者在非婚非商业异性性传播的风险上存在差异,应采取针对性的防治措施.

abstractsObjective To describe the characteristics of newly reported HIV/AIDS cases via non-marital or non-commercial heterosexual transmission and to find out the relative factors in Hangzhou,from 2015 to 2017.Methods Data were collected through the national HIV/AIDS comprehensive control and prevention data system.Study subjects would include those reported HIV/AIDS cases who were residents of Hangzhou and were infected via non-marital heterosexual transmission,between January 1,2015 and December 31,2017.Demographic characteristics and behavioral information were collected.x2 test was used to compare different characteristics of the non-married heterosexual transmission subjects.Logistic regression was used to assess factors that associated with non-marital but non-commercial HIV heterosexual transmission with SPSS.20 software used to analyze statistically.Results Non-marital HIV heterosexual transmission accounted for 38.03％ (1 393/3 663) of the total new reported HIV/AIDS cases in 2015-2017.Out of the 1 393 HIV/AIDS cases,those infected through non-marital but non-commercial heterosexual transmission accounted for 50.83％ (708/1 393),and those through non-martial commercial transmission was accounted for 49.17％ (685/1 393).Male to female ratio was 3.51 ∶ 1 (1 084/309).Male HIV cases reported that their major way of infection was via non-marital commercial transmission (670/1 084,61.81％),while female patients reported the way was via non-marital non-commercial (294/309,95.1％).Results from multivariate logistic analysis showed that the related risk factors and ORs for non-marital but non-commercial transmission appeared as:female (aOR=48.25,95％ CI:26.94-88.44),＜30 year olds (aOR=2.43,95％CI:1.3 1-4.5 1),30-39 year olds (aOR=1.92,95％CI:1.11-3.33),40-49 year olds (aOR=1.80,95％ CI:1.08-3.00),married or unmarried (vs.divorced or widowed,aOR=1.57,95％CI:1.10-2.24;aOR=1.78,95％CI:1.15-2.78),high school and above of education level (vs.primary school and under of education level,aOR=1.82,95％ CI:1.18-2.80),administrative officers or employee (vs.farmers,aOR=2.03,95％ CI:1.04-l.91).Number of non-marital partners less than 5 (vs.number of non-marital partners more than 5,aOR=10.65,95％CI:6.41-17.42).Conclusions HIV/AIDS cases with non-marital heterosexual transmission accounted for considerable proportion regarding the HIV transmission in Hangzhou from 2015 to 2017.Differences were found in the following factors as non-marital and non-commercial heterosexual transmission with diverse gender,age,marital status,educational level and occupation among of the HIV/AIDS patients.
