OBJECTIVETo investigate the status and influencing factors on knowledge, attitude and practice (KAP) about AIDS among the migrant workers in railway construction sites and to provide evidence for strategy development and measures on AIDS related health education and behavioral intervention.

METHODS943 migrant workers in railway construction sites were surveyed. Univariate analysis, multivariate Logistic regression and correlation analysis were used to explore their influencing factors.

RESULTSThe migrant workers in railway construction sites had poor AIDS knowledge as a whole. People with high educational level and income had higher AIDS correlative knowledge than other groups. Only 37.5% (275) of 734 migrant workers who had heard about AIDS felt pity 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" or "wenching". There were 90 (9.5%) migrant workers admitted having non-marital sex for the last three months but 22 (28.6%) admitted never using condoms,and only 8 (10.4%) had used each time. It appeared that the higher educational level and scores about AIDS knowledge one had,the higher the rate of using a condom. Both longer time interval away from their families and working time were, the lower they would usage a condom.

CONCLUSIONMigrant workers in construction sites were potential high risk population for HIV/AIDS. AIDS health education and behavioral intervention should be carried out
