Abstract:

目的系统评价我国艾滋病预防干预对控制长途汽车司机高危性行为的效果.方法计算机检索CBM光盘版(1978-2009)、CNKI(1980-2009)、VIP(1989-2009)以及MEDLINE (1950-2009)数据库发表的中国长途汽车司机艾滋病预防干预的文献,筛选自身前后对照试验或包括自身前后对照试验的空白对照试验.参考Newcastle-Ottawa scale,结合自身前后对照研究的特点评估纳入研究偏倚风险,采用RevMan 5.0软件进行统计分析.结果共纳入13篇文献,纳入研究存在发生偏倚的高度风险,Meta分析结果显示:(1)知识指标1:纳入7个研究,干预后长途汽车司机的知识指标1高于干预前(RD=0.15,95%CI:0.04～0.26).(2)知识指标2:纳入10个研究,干预后长途汽车司机的知识指标2高于干预前(RD=0.24,95%CI:0.17～0.30).(3)行为指标:纳入6个研究,干预后长途汽车司机的行为指标高于干预前(RD=0.15,95%CI:0.10～0.19).结论艾滋病预防干预对提高长途汽车司机的知识水平、促进其采取保护性性行为有一定的效果.

English Abstract:

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-posr'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.
