目的了解吸毒人群艾滋病和梅毒的感染状况,分析相关高危行为,为制定吸毒人群干预措施提供科学依据。方法收集山东省2012-2015年吸毒人群哨点监测资料,分析其人口学特征、毒品种类、行为学特征及艾滋病病毒(HIV)、梅毒感染状况。结果共调查吸毒者3 199人,97.9%吸食冰毒。最近一次发生性行为时使用安全套的占30.5%(640/2099),56.0%(1 793/3 199)最近一年与商业性伴发生过性行为,商业性行为时每次都使用安全套的比例为11.9%(214/1793)。2012-2015年HIV抗体阳性者3例,阳性率0.09%;梅毒阳性者369例,阳性率11.5%。各年的阳性率分别为7.1%、12.0%、13.1%、13.9%,呈上升趋势(χ2趋势=11.9,P<0.05)。结论山东省吸毒人群普遍存在高危性行为,安全套使用率低,梅毒感染率高,需要探索制定针对吸食冰毒等新型毒品者的干预措施。
Objective To understand the status of AIDS and syphilis infection among drug users and to analyze related high-risk behaviors so as to provide a scientific basis for formulating interventions for drug users. Methods The surveillance data of sentinel drug users in Shandong Province during 2012-2015 were collected and analyzed for their demographic characteristics, drug types, behavioral characteristics and HIV and syphilis infection status. Results A total of 3 199 drug abusers were investigated, 97.9% of them took methamphetamine. 30.5% (640/2099) of condom use on recent sexual intercourse, 56.0% (1 793/3 199) Condom use on commercial sex in the most recent year, percentage of condom use on commercial sex each time 11.9% (214/1793). 3 cases of HIV antibody positive in 2012-2015, the positive rate of 0.09%; 369 cases of positive syphilis, the positive rate of 11.5%. The positive rates of each year were 7.1%, 12.0%, 13.1% and 13.9%, respectively (χ2 = 11.9, P <0.05). Conclusions There is a high prevalence of sexual behavior among drug users in Shandong Province. The condom use rate is low and the syphilis infection rate is high. Therefore, it is necessary to explore and make interventions for new drug users such as methamphetamine.
