目的评估青少年群体性癔症(MH)罹患率的流行病学特征。方法采用文献综述和比较分析方法收集和整理数据,通过描述性分析和meta分析方法评估青少年MH罹患率,罹患率的计算采用纳入研究各罹患率组合加权方法。结果 95项研究(n=118 939人)被纳入meta分析,8 721名青少年罹患MH,64项研究文献质量评估中上等;青少年MH总罹患率为14.6%(95%CI=0.117~0.181,P<0.000 1),青少年MH时间、人群、地区分布特征罹患率范围分别为11.7%~25.3%、4.8%~25.8%和7.0%~23.9%,女性青少年MH罹患风险是男性青少年的2.9倍(95%CI=2.1~4.1,P<0.000 1)。结论青少年罹患MH具有不同的流行病学特征,青少年罹患M H可能与性别、民族、教育与经济状况、发病时间和地点、触发因子和不同首发病例等因素关联。
Objective To assess the epidemiological characteristics of adolescent hysteria (MH). Methods The literature review and comparative analysis were used to collect and collate the data. The destructive rates of MH in adolescents were evaluated by descriptive analysis and meta-analysis. The attack rates were calculated by using the combination weighted method. Results Ninety-five studies (n = 118,939) were included in the meta-analysis, with 8,721 adolescents suffering from MH, and 64 studies rated superior in quality. The overall prevalence of adolescent MH was 14.6% (95% CI = 0.117-0.181, P <0.0001). The attack rates of MH, time of population, and regional distribution in adolescents ranged from 11.7% to 25.3%, 4.8% to 25.8% and 7.0% to 23.9%, respectively. The risk of MH among female adolescents was 2.9 times that of male adolescents 95% CI = 2.1 ~ 4.1, P <0.000 1). Conclusions Adolescents with MH have different epidemiological characteristics. Adolescents with MH may be related to gender, ethnicity, educational and economic status, time and place of onset, triggers and different initial incidences.
