Brazilian High Risk Cohort Study (BHRC)
The BHRC is designed to understand the developmental trajectories of psychopathology and mental disorders. The study recruited children born between 1998 and 2004 living in Brazil through public schools in Sao Paolo and Porto Alegre. Close to 10,000 children were screened for family history of mental health conditions, from which a sample, aimed to be representative of the community, and a high-risk sample of children based on their parents’ history of a mental health condition, were selected. This resulted in over 2,500 participants at inception.
