江苏省2005~2008年吸毒人群艾滋病病毒哨点监测结果分析

目的:通过对2005～2008年江苏省吸毒人群艾滋病病毒(HIV)哨点监测结果的分析,了解该人群艾滋病感染状况及高危行为状况变化趋势,评价近年对吸毒人群的干预效果。方法:采用SPSS11.5统计软件对2005～2008年江苏省7个吸毒人群艾滋病哨点监测数据进行统计分析。结果:吸毒人群中艾滋病病毒抗体(HIV抗体)阳性率为0.7%,丙肝(HCV)阳性率为34.04%。注射吸毒率逐年呈下降趋势且有统计学差异(χ2=156.66,P<0.01);注射吸毒且共用针具者与注射吸毒但不共用针具者艾滋病感染状况有统计学差别(χ2=18.173,P<0.01);发生商业性行为时从不使用安全套的比例有逐年下降趋势(χ2=11.67,P<0.01)。此外,注射吸毒者HCV感染率与非注射吸毒者HCV感染率有统计学差异(χ2=708.945,P<0.01)。结论:在吸毒人群中普遍存在艾滋病、HCV等血源传染性疾病流行的风险,加强对吸毒人群的监测和防病知识宣传教育及行为干预,有利于控制诸如艾滋病、HCV等血源性疾病的传播和蔓延。

Analysis on sentinel surveillence results of HIV among drug users in Jiangsu during 2005~2008

Objective:To analyze the rate of HIV infection among drug users from Jiangsu in 2005~2008, understand the status of HIV infection and risk factors among drug users,and evaluate the effect of intervention on drug users. Methods:The data of surveillance among drug users in Jiangsu during 2005~2008 were analyzed by SPSS11.5. Results:Total of 7739 drug users were detected for HIV and HCV and the infection rate of HIV and HCV was 0.7% and 34.04%, respectively. The trend of injection rate among drug users was down from 2005 to 2008 and had significant difference that in(P < 0.01). The rate of HIV infection in sharing of syringes group was higher than the no-sharing group(P < 0.01). The trend of rate actives who never used condom in commercial sexual was down from 2005 to 2008(P < 0.01). In addition,HCV infection among drug users by injection was higher than that without injection(P < 0.01). The rate of HCV infection Compared with group, the rate of HIV infection in group was down from 2005 to 2008(P < 0.01). Conclusion:The risk really existed that bloodborne diseases,such as HIV and HCV,were transmitted and spread among drug users. It is necessary to enhance surveillance,education on the prevention of the diseases and behavioral intervention for drug users so as to reduce prevalence of bloodborne infectious diseases such as HIV and HCV.
