Epidemiology of child psychiatric disorders
This article needs to be updated.(November 2021) |
The epidemiology of child psychiatric disorders is the study of the incidence, prevalence, and distribution of conditions in child and adolescent psychiatry. Subfields of pediatric psychiatric epidemiology include developmental epidemiology, which focuses on the genetic and environmental causes of child psychiatric disorders. The field of pediatric psychiatric epidemiology finds widely varying rates of childhood psychiatric disorders, depending on study population, diagnostic method, and cultural setting.
Prevalence of mental illness
A 2016 study conducted in the United States found that 17.4% of children between the ages of 2 and 8 have a mental, behavioral, or mental health disorder.
England
Between 2005 and 2017, the number of adolescents (12 to 17 years) who were prescribed antidepressants has doubled. On the other hand, antidepressant prescriptions for children aged 5-11 decreased between 1999 and 2017.[4][5]
From April 2015, prescription increased for both age groups (for people aged 0 to 17) and peaked during the first COVID lockdown in March 2020.[6]
Between 1998 and 2017, children and adolescents living in deprived areas were more often prescribed antidepressants while Black, Asian and minority ethnic (BAME) teenagers were less likely to receive prescriptions than their White peers.[4][5]
Developmental epidemiology
Developmental epidemiology seeks to "disentangle how the trajectories of symptoms, environment, and individual development intertwine to produce psychopathology".[7]
Socio-economic influences
Mental illness in childhood and adolescence is associated with parental unemployment, low family income, being on family income assistance,[8] lower parental educational level, and single-parent, blended or stepparent families.[9]
Methodological issues
Epidemiological research has produced widely divergent estimates, depending on the nature of the diagnostic method (e.g. structured clinical interview, unstructured clinical interview, self-report or parent-report questionnaire), but more recent studies using
