Health Education And Behavioural Intervention For Preventing AIDS Among The Migrant Workers In Hefei's Large-Scale Railway Construction Unit

Objective To investigate the status and influencing factors of knowledge, attitude and practice (KAP) about AIDS among the migrant workers in railway construction sites and to provide evidence for constituting strategies and measures for AIDS health education and behavioral intervention.To evaluate the effect of behavioral intervention for the prevention of AIDS among the migrant workers in railway construction sites.Methods 943 migrant workers from two railway construction sites were surveyed by cluster sampling. Univariate analysis, multivariate Logistic regression and correlation analysis were used to explore their influencing factors of knowledge, attitude and practice about AIDS among the migrant workers. Health education and behavioral intervention on AIDS were carried out among the migrant workers for 4 to 5 months, which included mini-media, peer education and so on. Questionnaire survey was conducted among them before and after the intervention to evaluate the effect of behavioral intervention.Results The migrant workers in railway construction sites had poor AIDS knowledge as a whole. People with high educational level and income had higher AIDS-related knowledge than other groups. There were only 37.5% (275) of 734 migrant workers who heard about the name of AIDS sympathized for people with HIV/AIDS. There were 39.6%, 7.3% and 6.9% of 943 migrant workers did not object to"pre-marital sex","prostitution"and"wenching". There were 90(9.5%) migrant workers admitted having non-marital sex among three months before the survey, but 22(28.6%) admitted never using condoms, and only 8(10.4%) had used each time. The higher educational level and scores about AIDS knowledge were, the higher the usage of condom was. The longer time interval for visiting their families and working time were, the higher the usage of condom was.The results showed that the knowledge awareness of the migrant workers on the transmission routes, preventions of AIDS and self-protection consciousness increased significantly by comparing the indexes of 943 before-intervention with those of 671 after-intervention workers. After intervention procedures , the rate of those workers who would adopt negative attitudes towards the HIV infected persons because of fear and discrimination was decreased from 9.8%,10.5% to 6.3%, 3.5% (both P<0.05); the rate of those workers admitted having non-marital sex among three months before the survey was decreased from 24.8% to 3.8% (P<0.01); the rate of those workers, who used condoms recently once when having non-marital sex, was raised from 41.9% to 64.3% (P<0.05). There was no statistical significance in the usage of condoms of the subjects between before- and after-intervention among three months before the survey. There was no statistical significance in the scores about AIDS knowledge and self-protection consciousness of the subjects between 139 new migrant workers and the population of baseline survey. But the knowledge awareness on AIDS-related knowledge, positive attitudes towards the HIV infected persons and self-protection consciousness of 671 after-intervention workers were higher than those of 139 new migrant workers(P<0.01).Conclusions Migrant workers in construction sites are potential high risk population for HIV/AIDS. AIDS health education and behavioral intervention work should be carried out imminently. The behavioral intervention based on the construction sites for migrant workers were effective measures in AIDS prevention and control. But if altering migrant workers'high rish sexual behaviors on STI/AIDS, we need make unremitting efforts to carry through behavioral intervention.
