2010-2012年南京市浦口区吸毒人群艾滋病哨点监测分析

目的了解南京市浦口区吸毒人群艾滋病相关知识行为及HIV/HCV/梅毒感染现况。方法 2010-2012年根据《全国艾滋病哨点监测实施方案》要求,每年随机选取浦口区戒毒所新羁押吸毒人群400名进行问卷调查以及HIV/HCV/梅毒抗体检测。结果监测对象羁押前吸食的毒品主要为海洛因和冰毒,分别占71.1%、25.8%;注射吸毒者占46.8%,其中曾共用针具者占35.8%;发生过商业性行为者占12.8%,其中每次均使用安全套的比例为86.3%。3年间吸毒人群主要吸食海洛因的比例在逐年下降,而吸食冰毒的比例在逐年上升,注射吸毒比例呈逐年下降趋势(P0.001)。吸毒人群艾滋病知识的知晓率为99.4%,HIV、梅毒、HCV抗体阳性率分别为0.3%、7.6%、47.0%。有注射吸毒史者HCV抗体阳性率(61.7%)显著高于无注射吸毒史者(33.4%)(P0.001)。结论浦口区吸毒人群HIV感染率较低,但HCV感染率较高。注射吸毒比例呈现逐年下降趋势,但存在一定比例的共针行为。应继续对该人群进行艾滋病宣传教育及行为干预,加大监测力度。

Analysis of sentinel surveillance on HIV/AIDS among drug users in Pukou District from 2010 to 2012

Objective To learn about AIDS related knowledge, risk behaviors and the status of HIV/HCV/Syphilis infection among drug users in Pukou District, Nanjing. Methods Guided by ＂National HIV/AIDS Sentinel Surveillance Implementation Plan＂, 400 new detention drug users were selected by random sampling with anonymous questionnaires and HIV/HCV/ Syphilis test per year in drug relief reformatory in Pukou District. Results It was found that prior to detention, heroin and methamphetamine were mainly used for the target group with 71.1% and 25.8%, respectively. The injecting drug users were 46.8%, 35.8% of them were syringes sharing. There were 12.8% drug users ever had commercial sexual behavior, 86.3% of them had condom use with sexual behavior for every time. In drug users, the proportions of heroin use and injecting drug were decreased by years from 2010 to 2013 （P〈0. 001）, while methamphetamine use showed a rising trend （P〈0. 001）. The awareness rate of AIDS related knowledge was 99.4%. The prevalence of HIV/Syphilis/HCV infection were 0.3%, 7.6% and 47.0%, respectively. The positive rate of HCV antibody in injecting group （61.7 %） was significantly higher than that in non injection drug users （33.4%） （P〈0. 001）. Conclusion HIV infection rate was lower while HCV infection was higher for drug users in Pukou District. Mean time proportion of injecting drug use declined yearly while syringes sharing existed with certain proportion. Therefore, publicity campaign on HIV/AIDS and interventions should be conducted continuously and surveillance force should be strengthened for the drug users group.
