卫生研究

目的综合评价我国农村留守儿童的心理健康状况,为了解留守儿童存在的心理卫生问题及在留守儿童中开展心理健康教育提供依据。方法计算机检索中国生物医学文献光盘数据库(CBM)、万方数据库、维普数据库(VIP)、中国期刊全文数据库(CNKI)、PubMed等,并结合文献追溯的方法,收集1994～2009年在国内外公开发表的关于我国农村留守儿童心理健康状况调查研究的文献。文献研究类型为现况研究,测量工具为SCL-90。使用RevMan4.2软件,选择强迫、抑郁、焦虑等9个维度进行Meta分析。用加权均数差(WMD)作为效应指标,对纳入研究进行一致性检验后,采取固定效应模型或随机效应模型进行综合定量分析。结果共检索39篇文献,纳入8篇文献。Meta分析显示除"强迫"之外,其他8个维度WMD均有统计学意义(P<0.05);按抽样方法进行分层分析,结果发现,整群抽样除了"敌对"和"偏执",其他7个维度均有统计学意义(P<0.05);随机抽样除了"强迫",其他8个维度均有统计学意义(P<0.05)。敏感性分析显示结果可靠。结论农村留守儿童较之非留守儿童存在更多的心理健康问题。

Objective To evaluate the mental health status of the left-behind children in rural area. Methods A computerized literature search was carried out in PubMed,CBM (Chinese Biomedical Database),CNKI (Chinese National Knowledge Infrastructure),Wanfang ( Chinese),VIP ( Chinese) databases and so on,to collect articles published between 1994 and 2009 concerning the mental health status of the left-behind children in rural area. We also checked the reference lists of relevant articles. The study type was cross-sectional study and the survey instrument was SCL-90. Meta-analyses were performed to assess 9 dimensions,i. e. compulsion,depression, anxiety,etc. Fixed and random effect models were employed to combine results after a heterogeneity test,with weighted mean difference (WMD) used as the indicator of intervention effect. Results In total,39 literatures were searched and 8 literatures were included. Meta-analyses showed that there were statistical significance with WMD of 8 dimensions (P < 0. 05) except"compulsion". When the results from the Meta-analyses were stratified according to sampling methods,the outcomes showed that there were statistical significance with WMD of 7 dimensions ( P < 0. 05) except "hostility"and "paranoid"by using cluster sampling,and there were statistical significance with WMD of 8 dimensions (P < 0. 05) except"compulsion"by using random sampling. The sensitivity analysis did not change the pattern of results. Conclusion There were more serious mental health problems in the left-behind children than other children in rural area.
