The Economic Impact of Subthreshold and Clinical Childhoo Mental Disorders: Supplemental Material

Supplemental online material for the Journal of Mental Health article "The Economic Impact of Subthreshold and Clinical Childhood Mental Disorders".
Background: Mental disorders are common health problems associated with serious impairment and economic impact. Aims: To estimate the costs of clinical and subthreshold mental disorders in a sample of Brazilian children. Method: The High Risk Cohort Study is a community study conducted in two major Brazilian cities. Subjects were 6-14 years old children being registered at school. From an initial pool of 9,937 children, two subgroups were further investigated using a random-selection (n=958) and high-risk group selection procedure (n=1,554), resulting in a sample of 2,512 subjects. Mental disorder assessment was made using the Development and Well-Being Assessment. Costs for each child were estimated from the following components: mental health and social services use, school problems and parental loss of productivity. Results: Child subthreshold and clinical mental disorders showed lifetime mean total cost of $1,750.9 and $3,141.2, respectively. National lifetime cost estimate was $10.8 billion for subthreshold mental disorders and $12.8 billion for clinical mental disorders (values in US$ purchasing power parity). Conclusions: This study provides evidence that child mental disorders have a great economic impact on society. There is an urgent need to plan an effective system of care with cost-effective programs of treatment and prevention to reduce economic burden.
