摘要
目的分析2007—2012年广西壮族自治区（广西）吸毒人群人类免疫缺陷病毒（humanimmunodeficiencyvirus，HIV）阳性率及相关危险行为的变化趋势。方法通过全区多个市县设立HIV监测哨点，每年4—7月由统一培训的工作人员通过滚雪球抽样（社区）及连续采样（强戒所）的方法对吸毒人员开展面对面访谈，获取一般人口学、行为学等信息，并采血3—5ml检测HIV、梅毒及丙型病毒性肝炎（丙肝），数据采用SPSS20．0软件分析。结果吸毒人群HIV阳性率（中位数）从2007年13．9％下降到2012年5．7％，梅毒阳性率（中位数）从2007年3．4％上升到2012年6．0％；吸毒人群曾经共用针具率逐年下降，但2012年最近1个月共用针具率为14．0％，商业性行为比例逐年上升，安全套使用率提高不明显。结论2007—2012年广西吸毒人群HIV阳性率呈现逐年下降趋势，各年龄组吸毒人群HIV阳性检出率也在逐年下降。吸毒人群经静脉注射感染HIV呈减缓趋势，但针对吸毒人群的艾滋病综合干预仍不容松懈。
Objective To understand the infection status of HIV and related risk behaviors among the drug users in Guangxi from 2007 to 2012. Methods HIV sentinel surveillance system was established in Guangxi. The annum face to face interview was conducted among drug users sampled in communities and drug rehabilitation center during April-July to obtain their demographic and behavioral information, and blood samples （ 3 - 5 ml） were drawn to conduct HIV, syphilis, HCV tests. Software SPSS 20.0 was used for data analysis. Results The HIV positive rate （Median） increase the drug users declined from 13.9% in 2007 to 5.7% in 2012, the syphilis positive rate （Median） increase from 3.4% in 2007 to 6.0% in 2012. The needle sharing rate declined with year, but this rate once reached 14.0% in 2012. The proportion of drug users who had commercial sex increased with year, but the condom use rate increased slightly. Conclusion The HIV infection rate declined with year among the drug users in Guangxi, and the HIV infection through intravenous drug use became less common, but it is still important to strengthen the comprehensive HIV/AIDS intervention targeting drug users.
