To evaluate the mental health status of the left-behind children in rural area.
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.
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.
There were more serious mental health problems in the left-behind children than other children in rural area.
评估农村留守儿童的心理健康状况。
在PubMed、CBM（中国生物医学数据库）、CNKI（中国知网）、万方（中文）、维普（中文）等数据库进行计算机文献检索，收集1994年至2009年期间发表的有关农村留守儿童心理健康状况的文章。我们还查阅了相关文章的参考文献列表。研究类型为横断面研究，调查工具为SCL-90。进行Meta分析以评估9个维度，即强迫、抑郁、焦虑等。在进行异质性检验后，采用固定效应模型和随机效应模型合并结果，以加权平均差（WMD）作为干预效果指标。
共检索到39篇文献，纳入8篇文献。Meta分析显示，除“强迫”外，8个维度的WMD有统计学意义（P<0.05）。当根据抽样方法对Meta分析结果进行分层时，结果显示，采用整群抽样时，除“敌对”和“偏执”外，7个维度的WMD有统计学意义（P<0.05）；采用随机抽样时，除“强迫”外，8个维度的WMD有统计学意义（P<0.05）。敏感性分析未改变结果模式。
农村留守儿童的心理健康问题比农村其他儿童更为严重。
