Prevalence of child and adolescent psychiatric disorders in India: a systematic review and meta-analysis

BACKGROUND The importance of epidemiological studies lies in recognition of cases that do not come to treatment settings. The increasing focus on child adolescent mental health in India points to the necessity of epidemiological studies on children. Although there are a few such studies done in different parts of India in different socio-cultural settings, data from those cannot be generalized to the entire country. This need can be served by meta-analysis. There has been no meta-analysis reported from India for the child and adolescent psychiatric epidemiology. AIM To review and do the meta-analysis of epidemiological studies on child and adolescent psychiatric disorder from India. METHODS Sixteen community based studies on 14594 children and adolescents; and seven school based studies on 5687 children and adolescents, reporting prevalence of child and adolescent psychiatric disorder were analyzed and overall prevalence was calculated. RESULTS The prevalence rate of child and adolescent psychiatric disorders in the community has been found to be 6.46% (95% confidence interval 6.08% - 6.88%) and in the school it has been found to be 23.33% (95% confidence interval 22.25% - 24.45%). CONCLUSIONS This is the first meta-analysis determining the epidemiology of child and adolescent psychiatric disorders in India. It has been found that the reporting systems of psychiatric disorders in children are inadequate.
