目的了解广东省广州市吸毒人群的艾滋病相关知识、行为特征、性病感染和卫生服务利用情况。方法采用横断面方法,对广州市某强制戒毒所的戒毒学员进行自填问卷调查。结果433名戒毒学员对艾滋病的传播途径知晓程度相对较好,但对其他知识的知晓程度相对较差;75.9%发生过婚前性行为。入所前6个月与固定性伴侣、临时性伴侣、商业性伴侣和同性性伴侣发生过性关系的比例分别为62.1%,32.8%,16.2%和1.8%;发生性关系时每次均使用安全套分别占14.0%,19.0%,31.5%,12.5%;247人有静脉注射吸毒史,占57.0%。入所前6个月内有41人与别人共用过注射器,占静脉吸毒者的16.6%;女性性病率高于男性,差异有统计学意义(χ2=14.326,P<0.001);有139人曾经接受过有关艾滋病预防措施的服务,占31.1%。结论广州市吸毒人群对艾滋病相关知识有一定程度的了解,但普遍具有传播艾滋病的高危行为,且健康水平不高,艾滋病卫生服务利用率较低,应加强艾滋病的宣传、检测和咨询服务。 Objectives To understand AIDS-related knowledge, behavioral characteristics, STD infection and health service utilization among drug addicts in Guangzhou, Guangdong Province. Methods The cross-sectional method was used to conduct self-administered questionnaire survey on drug addicts in a mandatory detoxification center in Guangzhou. Results 433 drug addicts knew relatively well the AIDS transmission routes, but they were less aware of other knowledge and 75.9% had premarital sexual behaviors. Sexual relationships with fixed-sex partners, temporary partners, business partners and same-sex partners were 62.1%, 32.8%, 16.2% and 1.8% respectively in the first 6 months of the study. Condoms were used each time a sexual relationship occurred Accounting for 14.0%, 19.0%, 31.5% and 12.5%, respectively; 247 people had a history of intravenous drug abuse accounting for 57.0%. In the first 6 months before admission, 41 people shared the syringe with others, accounting for 16.6% of the intravenous drug addicts. The rate of STD in women was higher than that in men (χ2 = 14.326, P <0.001); 139 people once accepted Services on HIV prevention measures accounted for 31.1%. Conclusions There is a certain degree of knowledge about HIV / AIDS related knowledge among drug users in Guangzhou. However, high-risk AIDS-related behaviors are commonly reported in Guangzhou. However, their health is not high and the utilization rate of HIV / AIDS health services is low. HIV / AIDS awareness, testing and counseling services should be strengthened.
