目的了解药物滥用(drug abuse,DA)、同性性行为(HS)和商业性行为(prostitution,PT)HIV感染者的感染风险,为科学防控艾滋病(AIDS)提供依据。方法采用随机抽样方法选取DA,HS和PT HIV感染者113例,同类人员非HIV感染者202例,对其性交带安全套、每周性交次数、性道德观和HIV传播途径等进行问卷调查,计算患病率和OR值。结果性交带安全套、每周性交≤3次、认为应当遵守性道德和准确掌握HIV传播途径者HIV感染率为24.50%,28.21%,25.00%和18.30%,性交不带安全套、性交频率每周>3次、认为不应当遵守性道德和不掌握HIV传播途径者HIV感染率为46.34%,43.40%,47.68%和50.32%,两者差异均有统计学意义(P<0.01)。Logistic分析表明,DA,HS,PT,性交不带安全套,不遵守性道德和不掌握HIV传播途径等是HIV感染的重要危险因素,患病风险分别是5.3,2.9,8.2,2.4,3.9和4.2倍。结论 DA,HS,PT,安全套,性交频率,遵守性道德和HIV传播途径的认知力是防控AIDS的活跃因素,规范这些人群的性行为,使用安全套、减少性交频率、遵守性道德和提高人群HIV传播途径的认知力对防控HIV感染有益。
Objective To understand the risk of drug abuse (DA), homosexuality (HS) and prostitution (PT) infection among HIV-infected persons and provide basis for scientific prevention and control of AIDS. Methods One hundred and thirteen cases of DA, HS and PT HIV infection were selected by random sampling method. 202 cases of non-HIV infected persons of the same type were recruited. Questionnaires were conducted on the sexual intercourse condoms, frequency of sexual intercourse, sexual morality and HIV transmission Prevalence and OR values. Sexual intercourse without condom, frequency of sexual intercourse> 3 weeks, sexual intercourse without condom, frequency of sexual intercourse> 3 times. The prevalence of HIV infection was 46.34%, 43.40%, 47.68% and 50.32%, respectively. The difference was statistically significant (P <0.01). Logistic analysis showed that DA, HS, PT, condoms without condom, non-compliance with morals and non-possession of HIV transmission were all important risk factors for HIV infection. The prevalences were 5.3, 2.9, 8.2, 2.4, 3.9 and 4.2 respectively Times CONCLUSION Cognitive power of DA, HS, PT, condoms, frequency of sexual intercourse, adherence to ethics and HIV transmission is an active element in the prevention and control of AIDS, regulating sexual behavior in these populations, using condoms, reducing frequency of sexual intercourse, observance of ethics and promotion Cognition of HIV transmission in the population is good for preventing HIV infection.
