The adverse environmental factors inducing reduced GMV and rsFC in antisocial individuals remains unanswered. Since the exposure to increasing levels of traffic related air pollutants and adverse living environment is found to have significant detrimental impacts on mental health problems, this study aimed to investigate the environmental and neural factors of antisocial behaviors in Hong Kong youth and young adults. One hundred- sixty participants (130 healthy participants and 30 schizophrenia patients) were recruited and assessed at the baseline and one-year follow-up. Their mean age was 24 years old (SD= 8.76) and 34% of them were male. All participants underwent brain scans using magnetic resonance imaging (MRI). Their environmental estimates (e.g., greenspace density within a radius of 300 meters surrounding their home) and antisocial behaviors (e.g., Reactive-Proactive Aggression Questionnaire) were measured. The preliminary results showed that the exposure to adverse environmental factors and brain abnormalities in the frontal lobe at the baseline predicted antisocial behaviors at the 1-year follow-up. These findings have both theoretical and clinical implications. For instance, the policymakers may adopt new environmental measures to enhance brain functioning and reduce antisocial behaviors.enConference Paper
