Abstract:
Objective:To understand the related factors of tic disorders(TD) and early intervention among schoolchildren.Methods:Using stratified-cluster random sampling techniques,4,020 children were selected from 61,836 schoolchildren in Daxing district of Beijing.Totally 4,020 children and their parents were asked to fill in a self-designed questionnaire covering both motor and vocal tics and general information.A three-stage procedure was used:screening,interview and clinical investigation.A total of 3,813 children were investigated successfully.The children who were reported with tic symptoms as well as those who were reported by their teachers or classmates were surveyed according to the TD criteria in Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition(DSM-Ⅳ).Eighty-six TD children were investigated respectively about the related factors of TD,and 86 healthy children matched in age,sex and grade were selected as controls.Telephone interview was carried out to find the doubtful TD cases in family members.Those people identified as having tics underwent a semistructured interview to determine whether they had TD according to DSM-Ⅳ criteria.Related risk factors of TD were investigated according to self-designed formulary medical history sheet. Results:Positive TD inheritance family history(7.0%),abdominal delivery style(36.0%),carbonate drink(10.5%),obesity(14.0%) and psychological stress were risk factors of TD(P<0.05).The multivariate analysis of variance indicated that inheritance family history,delivery style,dwelling environment,carbonate drink,parent-child relation,hobby,underachieve,self-care ability were closely related to the high incidence of TD (P<0.05).Conclusion:The occurrence of tic disorders may be related to multiple interacted factors.Early intervention is most important.
