OBJECTIVE: To assess the efficacy of HIV/AIDS prevention and control among long-distance drivers in China. METHODS: Based on the principles and methods of Cochrane systematic reviews, we searched literature from CBM (from 1978 to 2009), VIP (1989 to 2009) CNKI (1980 to 2009), and MEDLINE (1950 to 2009) and also assessed the risk of bias of the included before-after studies according to Newcastle-Ottawa scale and their characteristics. Cochrane Collaboration’s software RevMan 5.0 was used for Meta-analysis. RESULTS: 13 studies were included, with most of them were of low quality as having high risk of bias. (1) Knowledge index 1: We included 7 ‘pre-post’ studies. Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the knowledge index 1 among long-distance drivers (RD = 0.15, 95%CI: 0.04 – 0.26). (2) Knowledge index 2: We included 10 pre-post studies, in which the results from Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the knowledge index 2 among long-distance drivers (RD = 0.24, 95%CI: 0.17 – 0.30). (3) Behavior index: We included 6 pre-post studies in which the results from Meta-analysis showed that AIDS/HIV prevention and control was effective in promoting the behavior index among long-distance drivers (RD = 0.15, 95%CI: 0.10 – 0.19). CONCLUSION: Current evidence demonstrated that HIV/AIDS prevention and control programs were effective.
