目的了解社区静脉吸毒人群(IDU)高危行为相关疾病重叠感染状况及影响因素,为开展行为干预工作提供基线资料。方法采用同伴推动抽样法(RDS)在清城区和连州市招募社区IDU;于2009年4-12月对调查对象进行问卷调查,并采集血样检测HIV、HBV、HCV和梅毒。结果共问卷调查社区IDU203人,62.07%曾与别人共用针具吸毒,最近6个月、最近1月以及最近1次与别人共针的比例分别为38.92%、26.11%、15.27%;40.87%最近1年有商业性行为,与商业性伴从不和每次使用安全套的比例分别为15.66%、33.73%,最近1次与商业性伴使用安全套的比例为57.83%;HIV、HBsAg、HCV和梅毒感染率分别为6.59%、18.56%、65.27%、11.38%,二重、三重和四重感染率分别为17.96%、6.59%、0;多因素Logistic回归模型分析结果表明本市户籍、累计入戒毒所次数多和曾共用针具吸毒是社区IDU高危行为相关疾病重叠感染的危险因素,商业性行为每次使用安全套和最近一年接受过性病艾滋病相关服务是保护因素。结论清远市社区IDU高危吸毒和性乱行为仍较普遍,安全套使用率较低,高危行为相关疾病感染率较一般人群高,不安全注射吸毒和不安全性行为是主要危险因素,有必要广泛、持久地在吸毒人群中开展艾滋病性病相关知识宣传教育和行为干预活动。

Methods Community-based IDU was recruited by peer-driven sampling method (RDS) in Qingcheng District and Lianzhou City. From April to December 2009, questionnaires were conducted on the surveyed subjects and blood samples were collected for detection of HIV, HBV, HCV and syphilis. Results A total of questionnaire surveyed community IDU203 people, 62.07% had shared needles with others to take drugs, the proportion of the most recent 6 months, the most recent 1 month and the last one was 38.92%, 26.11% and 15.27% respectively; 40.87% 1 year of commercial sex with commercial partners and 15.66%, 33.73% respectively of condom use and 57.83% of commercial condom use lately; HIV, HBsAg, HCV and syphilis The infection rates were 6.59%, 18.56%, 65.27% and 11.38% respectively, and the rates of double, triple and quadruple infection were 17.96% and 6.59% respectively. The multivariate logistic regression analysis showed that the registered permanent residents The frequency and frequency of sharing needles is a risk factor for overlapping infections among high-risk behavior-related diseases in community-based IDUs. Commercial sex Use of condoms and STD-related services in the recent year are protective factors. Conclusion High-risk drug abuse and sexual disorder are still common among IDUs in community of Qingyuan City.
