玉溪市2006-2011年新报告HIV-1感染者中新近感染比例及其影响因素

Proportions and Correlates of Recent HIV Infections Among Newly Reported HIV-1 Cases from 2006 Through 2011 in Yuxi Prefectures

目的探究云南省玉溪市2006-2011年新报告HIV-1感染者中新近感染比例及其影响因素。方法对玉溪市2006-2011年新报告HIV-1阳性的血清采用微量Hl V-1抗体明胶颗粒凝聚法（ML-PA）方法检测以确定新近感染者,并分析相关的影响因素。结果 2006-2011年玉溪市累计新报告HIV感染者2 018例,其中64例（3.17%）为新近感染者,各年新近感染比例依次为6.91%,1.90%,2.83%,2.66%,2.40%和3.48%。Logistic多因素回归分析显示,在控制了各变量间的混杂作用影响后,女性新近感染者高于男性,16~35岁青壮年高于其他年龄组,未婚及同居者高于已婚者,大专及以上文化程度高于其他文化程度,娱乐场所服务人员及驾驶员高于其他职业,男男同性性传播新近感染比例较高。结论 2006-2011年云南省玉溪市新报告HIV-1感染者中新近感染比例保持较低水平,新近感染被多种因素影响。

Objective To discuss the proportions and correlates of recent HIV infections among newly reported HIV-1 cases from 2006 through 2011 in Yuxi prefectures,Yunnan province. Methods All available serum samples of newly reported HIV / AIDS cases during 2006- 2011 in Yuxi prefecture,were tested using the ML-PA HIV incidence method,thus,we can get the new infection proportions and analyze its correlates.Results A total of 2018 HIV / AIDS cases were newly reported in 2006 to 2011,64 of which（3. 17%）are new HIV-1-infected ones. The proportion of recent HIV-1 infection among newly reported HIV / AIDS cases was 6. 91%（17 /246） in 2006,1. 90%（6 /316） in 2007,2. 83%（ 11 /389） in 2008,2. 66%（ 10 /376） in 2009,2. 40%（9 /375） in 2010,and 3. 48%（11 /316） in 2011. Multiple logistic regression analysis indicated that the proportion of recent HIV infections among newly reported HIV / AIDS cases were all significantly which the females higher than males,the 16 ~ 35 years old group higher than others,unmarried ＆ cohabitation higher than married,junior college and higher education level higher than others,entertainment waiters and drivers higher than others,and men who have sex with men higher than others.
