目的分析评估中外青少年罹患流行性癔症(EH)特征的差异。方法采用文献综述和比较分析的方法收集和整理数据,通过描述性分析和Meta分析的方法评估青少年EH罹患率的流行病学特征,罹患率的计算采用纳入研究各罹患率组合加权方法,采用R软件3.2.0提供的随机效应模型估计青少年EH合并罹患率。结果 54篇文献(N=100 617人)被纳入Meta分析,5 789名青少年罹患EH。54篇研究文献质量评估均为中上等。中国青少年EH总罹患率[15.3%,95%CI(0.115~0.200),P<0.000 1]比国外[11.8%,95%CI(0.094~0.144),P<0.000 1]高,中外青少年EH的流行病学特征罹患率范围分别为5.4%~31.8%、5.6%~31.9%;不同特征罹患率比较分析,除了高中、小学、大气污染和春季的青少年EH罹患率低于国外,其他特征的EH罹患率均是中国青少年高于国外青少年。结论中外青少年罹患EH的流行特征存在差异,青少年EH发生可能与生活方式、教育模式、社会心理和文化因素以及社会人口学背景等因素关联。
Objective To analyze and evaluate the differences of characteristics of epidemic hysteria (EH) among adolescents in China and abroad. Methods The data were collected and analyzed by literature review and comparative analysis. The epidemiological characteristics of adolescent EH attack rate were evaluated by descriptive analysis and Meta-analysis. The attack rate was calculated by using the combination weighted method of each attack rate and R The random effects model provided in Software 3.2.0 estimates the incidence of adolescent EH co-morbidities. Results 54 articles (N = 100 617) were included in the meta-analysis and 5 789 adolescents had EH. The quality of the 54 research articles are of the highest quality. The overall incidence of EH in adolescents in China was higher than that in other countries (11.8%, 95% CI: 0.094-0.1444, P <0.0001), 15.3% (95% CI: 0.115-0.200) Epidemiological characteristics of the attack rate range from 5.4% to 31.8%, 5.6% to 31.9%; different characteristics of the attack rate comparison analysis, in addition to high school, primary school, air pollution and youth adolescent EH attack rate is lower than abroad, other characteristics of EH Attack rates are higher than young people in China adolescents abroad. Conclusions The prevalence of EH in adolescents in China and other countries is different. The occurrence of EH in adolescents may be related to lifestyle, educational patterns, social psychological and cultural factors, and socio-demographic background.
