MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Conduct problems (CP) are the most common reason for child treatment referral in the UK, costing an estimated £22 billion per year. Children with CP engage in a range of aggressive and antisocial behaviours (e.g. fighting, stealing, lying), that affect their ability to follow rules and adapt to society, do well in school, and form healthy relationships. Those who do not receive treatment are also at increased risk for many negative outcomes in adulthood, including lower job prospects and earnings, more contact with the police and a lower quality of life. Therefore, it is important to understand how CP develop in the first place, in order to create more effective prevention and intervention strategies.

Studies have found that children who develop conduct problems before the age of 10 (early-onset CP) are at greatest risk for poor outcomes across the lifespan. Compared to other children, those showing early-onset CP tend to have experienced more adversity in early life (e.g. prenatal stress, poverty) as well as having more genetic risk. However, little is known about about how genetic factors interact with environmental influences – especially during foetal development – to increase the risk for early-onset conduct problems.
