摘要
目的综合评价以健康教育为主的干预措施对中国中小学生伤害控制的效果,为伤害控制相关部门决策提供科学依据。方法应用Meta分析对纳入的多项研究进行定量综合分析;采用Peto法估计同质资料的综合效应值及其95%可信区间,异质资料则用随机效应模型(D-L法)。结果共纳入原始文献7篇,各研究结果不同质(Q=583.9585>χ(20.005,6),P<0.005)。假定中国某地区干预前中小学生伤害发生率为x%,则以健康教育为主的干预措施的保护率PR=1-1/(3.6324-0.026324x),其95%CI为[1-1/(2.0018-0.010018x),1-1/(6.5912-0.055912x)]。结合中国中小学生伤害发生率约为50%的现况,可得PR=56.83%,此类干预将使中小学生伤害在原来发生率基础上下降56.83%。结论以健康教育为主的干预措施对控制中国中小学生伤害是卓有成效的,值得大力推广。
Objective To synthetically evaluate the effect of intervention measures which are mainly composed of health education on pupils and middie school students＇ injury control in China. Methods Meta-analysis was used to synthetically and quantitatively evaluate the studies included. The Peto method and random effects meta-analyses（ DerSimonin and Laird） were applied to estimate combined effect values and their corresponding 95% confidence intervals of homogenous and inhomogenous data respectively. Results Seven pieces of literature included were inhomogenous（ Q = 583.9 585〉 ×210.00%,61, P 〈 0.005）. Supposing the injury prevalence rate of primary and secondary school students before intervention in a certain area in China is x%, protective rate （ PR） of intervention measures mainly composed of heath education will be equal to 1 - 1/（ 3. 632 4 - 0.026 324x ）, and its 95 % CI will be [ 1 - 1/（ 2.001 8 - 0.010 018x）, 1 - 1/（6.591 2 - 0.055 912x） ]. The injury prevalence rate of primary and high school students in China was about 50%, and as far as it was concerned, the PR will be 56.83%. The injury prevalence rate among primary and high school students will reduce by 56.83% due to the intervention. Conclusion Intervention measures against injury control among pupils and middle school students which are mainly comprised of health education are effective and of great worth applying widely in China.
