2010—2016年广西15～24岁新发现HIV/AIDS病例流行特征分析

Analysis on the Epidemic Characterization of Newly Occurred HIV/AID Scases aged 15～24 years in Guangxi during 2010—2016

目的了解2010—2016年广西15~24岁新发现艾滋病病毒(HIV)感染者/艾滋病(AIDS)病人(简称HIV/AIDS)的流行病学特征,为控制艾滋病在青少年人群中的传播提供决策依据。方法收集2010—2016年广西新发现年龄在15~24岁HIV/AIDS疫情资料,采用描述性流行病学方法分析。结果 2010—2016年广西新发现HIV/AIDS病例76 502例,其中15~24岁4 407例,占5.76%。2010—2016年,新发现报告15~24岁病例数逐年下降,但新发现报告15~24岁学生病例数逐年上升,差异有统计学意义(趋势χ2=175.185,P<0.001)。15~24岁病例中,男性占54.23%,女性占45.77%;职业以农民为主(39.75%),其次为家政、家务及待业(24.57%)和学生(9.96%);未婚占67.69%,初中文化占52.92%;样本来源以检测咨询(32.95%)和其他就诊者检测(17.54%)为主;传播途径以异性为主(75.88%),同性性传播占的比例逐年增高;报告同性性传播的15~24岁病例中,学生所占比例(62.64%)明显高于非学生(13.04%),差异有统计学意义(χ2=673.861,P<0.001)。结论2010—2016年以来广西新发现15~24岁HIV/AIDS病例数逐年下降,但学生病例数逐年上升;以异性性传播为主,同性性传播已成为HIV主要感染途径,应采取有针对性的措施降低HIV对该人群的危害。

OBJECTIVE To studyepidcmiological characteristics of newly occurred HIV/AIDS cases aged 15~24 years in Guangxi dur- ing 2010---2016 , thus providing scientific basis for HIV controlamongyoungsters. METHODS The epidemic data of newly occurred HIV/AIDS cases aged 15~24 years in Guangxi during 2010--2016 were collected and analyzed with descriptive epidemiology. RE- SULTS A total of 76502HIV/AIDS cases were newly reported in Guangxiduring 2010--2016, and those aged 15~24 years accounted for 5.76%（4407/76502）. The number of newly diagnosed and reported HIV/AIDS cases aged 15~24 years decreased by years during 2010-2016, while the students cases aged 15~24 yearsincreased by years, with significant difference （x2=175.185, P〈0.001）： Among cases aged 15~24 years, male were 54.23% and female were 45.77%. The majority of the cases were farmers（39.75%）, fol- lowed by housekeepers/houseworkers/the unemployed（24.57%） and students（9.96%）. Of those, 67.69% were unmarriedand the ones with cultural level of junior middle school made up to 52.92% of the cases. Most of the samples sources were VCT（32.95%） and other clinic clients（17.54%）. The main transmission route was heterosexual contact（75.88%） while cases infected by homosexual contactin- creased year by year. Among cases aged 15~24 years infected by homo contact, the proportion of students （62.64%） was obviously higher than non-students（13.04%） and there was significant difference（x2=673.861, P〈0.001）. CONCLUSIONS The cases of newly oc- curred HIV/AIDS cases aged 15~24 years in Guangxi during 2010--2016 decreased by years, while the cases of students increased year by year. Heterosexual contact was the main transmission route, and ＇so was homo contact. Pertinence measures should be taken to reduce the harm to the population.
