目的了解少数民族流动人口艾滋病高危性行为现况,分析流动模式对艾滋病高危性行为的影响。方法 2012年7-10月,采用分阶段抽样方法 ,在贵州省兴义市、七星关区、威宁县少数民族流动人口就业集中的工厂、建筑工地、服务场所随机抽取845名有性交行为的流动人口进行艾滋病高危性行为一对一面访匿名问卷调查,统计分析采用多元Logistic逐步回归方法。结果少数民族流动人口艾滋病高危性行为(商业性行为或临时性伴侣性行为或多性伴性行为)构成比为66.8%,高于汉族流动人口49.8%的艾滋病高危性行为构成比(P<0.01)。不同民族、性别、年龄、婚姻状况、迁移类型、流动城市(镇)数等特征的流动人口艾滋病高危性行为比较,差异有统计学意义。苗族、布依族流动人口较汉族流动人口易发生艾滋病高危性行为,OR值分别为3.88,2.08;男性流动人口较女性流动人口、迁移类型为跨县或跨乡流动人口较跨省流动人口、流动城市(镇)数3个的流动人口较流动城市(镇)数1个的流动人口易发生艾滋病高危性行为,OR值分别为2.37,1.75,2.27,2.17;年龄≥35岁的流动人口较15~24岁的流动人口不易发生艾滋病高危性行为,OR值为0.55。结论少数民族流动人口发生艾滋病高危性行为的概率高于汉族流动人口;迁移类型、流动城市(镇)数对艾滋病高危性行为有影响。
Objective To understand the status quo of HIV / AIDS high risk behaviors among minority migrants and analyze the impact of mobility patterns on HIV / AIDS risk behaviors. Methods From July to October 2012, a sample of 845 migrant workers was selected randomly from factories, construction sites and service establishments in Xingyi City, Qixingguan District, Weining County where ethnic minority migrants are concentrated in employment in a phased sampling method. One-on-one interview with anonymous questionnaires was conducted among the population for high-risk sexual behaviors of AIDS. The statistical analysis adopted the multiple Logistic stepwise regression method. Results The proportion of HIV / AIDS high risk behaviors (commercial sex or temporary partner sex or multi-sex sexual behavior) among ethnic minority migrants was 66.8%, which was higher than that of 49.8% of floating population (P <0.01) ). There were significant differences in HIV / AIDS risk behaviors among floating population with different ethnic groups, gender, age, marital status, type of migration and number of mobile cities (counties). Miao and Buyi ethnic migrants are more likely to have HIV / AIDS than migrants, with ORs of 3.88 and 2.08, respectively. Migrants are more migrant than females and migrants are more transatlantic than migrants The number of floating population in 3 counties (cities) is higher than that of 1 floating population in mobile cities (counties), with ORs of 2.37,1.75,2.27 and 2.17 respectively. The floating population aged 35 and older is 15 The 24-year-old floating population is not prone to AIDS-related high-risk sexual behaviors with OR of 0.55. Conclusion The probability of AIDS-related high-risk behaviors of migrant ethnic minority population is higher than that of Han migrant population. The type of migration and the number of mobile cities (towns) have an impact on the high-risk sexual behaviors of AIDS.
