目的探索广东省中山市艾滋病自愿咨询检测(VCT)HIV抗体阳性率及影响因素。方法从《中国疾病预防控制信息系统》下载2010—2012年广东省中山市艾滋病VCT数据;对参加VCT的人员进行HIV、梅毒血清学检测;在描述性分析基础上,对影响HIV阳性率的因素进行单因素分析和多因素非条件logistic回归分析。结果广东省中山市设置3个VCT点,2010—2012年对3 613人次提供服务,其中3 601人次(99.7%)接受HIV抗体检测,阳性率5.9%(212/3 601),其中男性、女性HIV抗体阳性率分别为:5.8%(173/2 972)、6.2%(39/629);2 759人次接受梅毒抗体检测,梅毒阳性率4.4%(121/2 759),其中男性、女性梅毒阳性率分别为4.9%(117/2 389)、1.1%(4/370)。梅毒阳性者的HIV阳性率为25.6%(31/121)。不同求询原因人群HIV阳性率分别为:既往检测怀疑阳性66.7%(8/12),既往输血卖血史17.6%(3/17),固定性伴阳性13.1%(29/221),注射吸毒12.7%(8/63),男男性行为人群(MSM)10.4%(114/1 096),性病史6.3%(3/48),固定性伴高危行为人群5.9%(4/68),母亲阳性3.0%(1/33),非婚异性性行为2.5%(22/896),商业异性性行为人群2.4%(20/825);职业暴露、母亲之外其他家庭成员阳性、拔牙、针刺等不安全行为、健康检查和恐艾人群均未发现阳性者。多因素logistic回归结果表明:文化程度越低(AOR=1.39),HIV阳性的风险越高;相对于梅毒阴性者,梅毒阳性者HIV阳性的风险更高(AOR=4.14);MSM、固定性伴阳性人群HIV阳性的风险分别高于非婚异性性行为人群(AOR=4.78、4.71,均P<0.01)。结论中山市接受VCT服务的人群中,文化程度低、梅毒抗体阳性、MSM及固定性伴阳性人群有着更高的HIV感染率,需要在这些人群中开展更加有效的综合防治工作。
Objective To explore the prevalence and influencing factors of HIV antibody in voluntary counseling and testing (VCT) of HIV / AIDS in Zhongshan City, Guangdong Province. Methods The AIDS VCT data of Zhongshan City, Guangdong Province from 2010 to 2012 were downloaded from China Disease Prevention and Control Information System. HIV and syphilis serological tests were performed on VCT staff. Based on the descriptive analysis, the influencing factors of HIV positive rate Univariate analysis and multivariate non-conditional logistic regression analysis. Results Three VCT sites were set in Zhongshan City, Guangdong Province, and 3,133 were served from 2010 to 2012. Among them, 3 601 (99.7%) were tested for HIV antibody, with a positive rate of 5.9% (212/3601), of which male and female The positive rates of HIV antibodies were 5.8% (173/2 972) and 6.2% (39/629), respectively. The positive rate of syphilis was 2 759 (211/2 759) in syphilis, of which male and female were positive for syphilis Rates were 4.9% (117/2 389) and 1.1% (4/370) respectively. The positive rate of HIV in syphilis was 25.6% (31/121). The prevalence rates of HIV in different groups were as follows: 66.7% (8/12) of the suspected positive cases, 17.6% (3/17) of the previous blood transfusions, 13.1% (29/221) of positive fixed sex partners, (8/63), MSM 10.4% (114/1 096), STD history 6.3% (3/48), and those with high-risk sexual behavior were 5.9% (4/68), mothers were positive 3.0% (1/33), 2.5% (22/896) for non-marital sexual behavior and 2.4% (20/825) for commercial heterosexual sex; occupational exposure, positive family members other than mothers, tooth extraction and acupuncture Unsafe behavior, health checks and fear of AIDS-free population were found no positive person. Multivariate logistic regression results showed that the lower the educational level (AOR = 1.39), the higher the risk of HIV positive; the risk of HIV positive was higher for syphilis positive than that of syphilis negative (AOR = 4.14); MSM, The positive rate of HIV positive in positive population was higher than that of non-same-sex population (AOR = 4.78, 4.71, both P <0.01). Conclusions Among the population of patients receiving VCT in Zhongshan City, people with low education level, positive syphilis antibody, positive MSM and fixed sex partners have a higher HIV infection rate, and more effective integrated prevention and control work needs to be carried out in these populations.
