Violence and Injury Prevention

Youth violence

Youth violence dramatically increases health, welfare and criminal justice costs; reduces productivity; and generally undermines the fabric of society. Beyond deaths, injuries and psychological harm, youth violence can lead to increased health risk behaviours such as smoking, substance abuse, unsafe sex, and further violence. These in turn are associated with chronic respiratory diseases, cancer, cardiovascular diseases, diabetes, early pregnancy and sexually transmitted diseases. Effective prevention and response strategies include those that promote parenting and early childhood development; school-based bullying prevention, academic, and life and social skills development programmes; therapeutic approaches with high-risk individuals, and community- and society-level approaches like reducing access to and misuse of alcohol and firearms, hotspots and problem-oriented policing, urban upgrading, and poverty de-concentration.
