泸州市艾滋病异性传播病例高危性行为史调查分析

目的 调查了解泸州市艾滋病病毒(HIV)感染者经异性传播的具体来源。 方法 招募经异性性行为传播的HIV感染者,采用深入访谈的方式调查其诊断HIV之前高危性行为信息和方式,分析其感染HIV最可能的时间和地点。 结果 对300名经异性性行为感染HIV的感染者的调查表明,男性和女性感染HIV的方式差异有统计学意义(χ²=164.834,P<0.001),男性以商业异性性行为为主(90.8%),另外固定性伴性行为占5.1%,临时异性性行为4.1%;而女性中以固定性伴性行为为主(71.9%),商业异性性行为占17.1%,临时异性性行为11.0%。自述经过商业异性性行为感染HIV的调查对象中,25.9%的人自述曾在2个以上地市发生过商业性行为,25.0%在2个及以上的省份发生过商业性行为;64.3%的调查对象自我判断在泸州市感染,而认为自己是在户籍地以外的其他省份感染HIV的调查对象占29.3%。 结论 泸州市艾滋病经异性性传播的情况较为复杂,亟需系统而全面地在全人群和重点人群中开展健康教育和行为干预工作。

History of high-risk sexual behavior among HIV/AIDS cases involving heterosexual transmission in Luzhou City

Objective To investigate the sources of HIV/AIDS infections through heterosexual transmission in Luzhou City. Methods HIV-infected/AIDS patients involving heterosexual transmission were enrolled for a face-to-face interview in Luzhou City. Demographic characteristics and modes concerning high-risk sexual behavior before HIV diagnosis among the patients were collected to identify the most likely time and venues for their HIV infection. Results Three hundred HIV-infected/AIDS patients through heterosexual transmission were interviewed in Luzhou City. There was a statistically significant difference in the routes of HIV infection between male and female patients(χ²=164.834,P<0.001). Commercial sexual contact was the most common route in male patients (90.8%), followed by sexual contact with a regular partner (5.1%) and casual sexual contact (4.1%). Sexual contact with a regular partner was the prevailing route in female patients (71.9%), followed by commercial sexual contact (17.1%) and casual sexual contact (11.0%). Among the self-reported patients with HIV infection through commercial sexual contact, 25.9% self-reported to have commercial sexual activities in two or more cities, and 25.0% in two or more provinces. About 64.3% self-identified that they were infected with HIV in Luzhou City, and 29.3% thought their HIV infection took place out of their home provinces. Conclusions HIV epidemics caused by heterosexual transmission in Luzhou City are complex and widely affected. It is necessary to continue implementation of the targeted health education and intervention among general population and key affected population.
