43例海洛因依赖者HIV感染情况分析

目的：了解海洛因滥用者HIV感染情况并分析其相关因素。方法：对我院2005年、2006年两年收治的4481例海洛因依赖者进行HIV血清抗体检测，初筛阳性者填写HIV／AIDS感染个案调查登记及流行病学调查表并上报上级防疫部门进行复查确诊。结果：4481例海洛因滥用者中HIV抗体阳性者43例占0.96％，其中2005年10例占0.42％（10／2367），2006年33例占1.56％（33／2114），两年比较差异有显著性（P〈0．01），所有感染者均为静脉注射吸毒者，其中42例有共用注射器情况。43例HIV感染者均有性乱行为。结论：静脉注射特别是共用注射器是造成HIV在吸毒群体中迅速传播的危险因素，性乱行为加速了HIV从吸毒人群到普通人群的蔓延。因此，加强对吸毒人群特别是注射毒品者进行教育和行为干预，改变吸毒者的认知及行为方式，拒绝共用注射器，拒绝性乱行为，能有效地避免HIV／AIDS的传播。

Analysis of HIV infection in 43 heroin addicts

Objective： To investigate HIV infection in heroin addicts and analyze the correlative factor. Methods：HIV antibody detection was conducted in 4481 heroin addicts who were hospitalized in 2005 and 2006. The addicts with positive result filled out HIV/AIDS infection questionnaire and epidemiology questionnaire. Two questionnaires were reported to superior epidemic prevention department to get callback and reconfirmed. Results： 43 （0.96%） were reported HIV-positive among 4481 heroin addicts, 10 （0.42%） in 2005 and 33 （1.56%） in 2006 （P （0.01）. They were all injection drug users with improper sexual behavior while 42 shared syringes. Conclusions： Intravenous injection, especially sharing syringes caused HIV rapid transmitting in drug abusers. Improper sexual behavior is the most minatory factor of HIV prevalence by accelerating spread of HIV from drug abusers to common group. It＇s the effective method to avoid the spread of HIV/AIDS, by enhancing the education and behavior intervention in drug addicts （especially the injection drug users）, influencing their cognitive and behavioral styles to decline sharing syringes and improper sexual behavior.
