摘　　要：目的掌握农民工人群艾滋病相关知识水平、实施艾滋病预防行为的动机、行为技巧以及农民工人群的性行为情况,探讨信息-动机-行为技巧(IMB)模型在农民工人群的适用性及艾滋病预防行为的影响因素。方法在哈尔滨地区抽取建筑工地21处,用自制问卷对工地的农民工进行现场匿名调查。资料应用Epidata3.1软件进行数据录入,使用SAS 9.1软件进行资料整理与统计分析,应用AMOS 18软件进行IMB模型的结构方程模型分析。结果农民工艾滋病基本知识知晓率为58.21%。不同文化程度以及不同家庭住址艾滋病基本知识知晓率存在差别。在所调查人群中,有固定性伴的人数占总人数的82.29%,有过固定性伴以外性行为的人数占总人数的17.58%。固定性伴性行为及非固定性伴性行为中,每次都使用安全套的比例分别为2.42%和8.20%。非固定性伴性行为的人数占总人数的14.41%,而其中安全套使用者占54%。IMB模型拟合良好(c2=184.995,DF=59,NC=3.136,RMR=0.076,RMSEA=0.079,GFI=0.927,CFI=0.915)。动机对行为技巧的回归系数为0.634,行为技巧对行为的回归系数为0.627,信息对行为技巧及行为的回归系数无统计学意义。动机对行为的回归系数无统计学意义。结论农民工人群艾滋病知识结构不平衡,对血液传播及性行为传播途径掌握程度高,对非传播途径和预防措施掌握程度低。农民工人群性行为时安全套的使用率低。IMB模型在农民工人群适用。动机和行为技巧是影响艾滋病预防行为的重要因素,其中行为技巧直接影响预防行为,动机通过激发行为技巧来间接影响预防行为。Objective To investigate migrant workers＇ AIDS-related knowledge level,the motivation of implementing AIDS-preventive behavior,behavioral skills and sexual behavior. To explore the applicability of information-motivation-behavioral skills（ IBM） model in the migrant population and the influencing factors of HIV /AIDS preventive behavior. Methods We adopted the random sampling in 21 construction sites in Harbin and surveyed migrant workers anonymously with self-made questionnaires. Epidata 3. 1 was used for data entry,SAS9. 1 was used for sorting and analyzing data and AMOS 18 was employed to perform structure equation model（ SEM） analysis. Results The awareness rate of AIDS-related knowledge of the migrant workers was 58. 21%. There were statistically significant differences in the awareness rate of basic AIDS-related knowledge among the migrant workers with different educational backgrounds and different home address. Among the population surveyed,82. 29% had a fixed sexual partner and 17. 58% had non-spouse sexual partners besides a fixed sexual partner. The proportions of the workers using a condom with a regular sexual partner and with non-regular sexual partners during every sexual intercourse were 2. 42% and 8. 20%,respectively. The proportion of the workers having sexual behavior with non-regular sexual partners was 14. 41%,and the condom users accounted for 54%. The IMB model fitted well（ c2= 184. 995,DF = 59,NC= 3. 316,RMR = 0. 076,RMSEA = 0. 079,GFI = 0. 927,CFI = 0. 915）. The regression coefficient on behavioral skills of motivation was 0. 634 and behavioral skills＇ regression coefficient on behavior was 0. 627. No statistical significance was found in the regression coefficients of information on behavioral skills and behavior as well as motivation on behavior. Conclusions The migrant workers＇ AIDS-related knowledge structure is imbalanced,knowing well the knowledge about the spread of AIDS through blood-borne transmission and sexual contact,but rarely knowing knowledge on non-transmi
