Violence is defined by the World Health Organization as the intentional use of physical force or power, threatened or actual, against a person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation. This definition associates intentionality with the committing of the act itself, irrespective of the outcome it produces. Globally, violence takes the lives of more than 1.5 million people annually: just over 50% due to suicide, some 35% due to homicide, and just over 12% as a direct result of war or some other form of conflict. For each single death due to violence, there are dozens of hospitalizations, hundreds of emergency department visits, and thousands of doctors' appointments. Furthermore, violence often has lifelong consequences for victims' physical and mental health and social functioning and can slow economic and social development. Violence, however, is preventable. Evidence shows strong relationships between levels of violence and potentially modifiable factors such as concentrated poverty, income and gender inequality, the harmful use of alcohol, and the absence of safe, stable, and nurturing relationships between children and parents. Scientific research shows that strategies addressing the underlying causes of violence can be effective in preventing violence. Examples of scientifically credible strategies to prevent violence include nurse home-visiting and parenting education to prevent child maltreatment; life skills training for children ages 6Ц18 years; school-based programmes to address gender norms and attitudes; reducing alcohol availability and misuse through enactment and enforcement of liquor licensing laws, taxation and pricing; reducing access to guns and knives; and promoting gender equality by, for instance, supporting the economic empowerment of women
The World Health Organization (WHO) is a specialized agency of the United Nations (UN) that is concerned with international public health. It was established on 7 April 1948, with headquarters in Geneva, Switzerland, and is a member of the United Nations Development Group. Its predecessor, the Health Organization, was an agency of the League of Nations. The constitution of the World Health Organization had been signed by all 61 countries of the United Nations by 22 July 1946, with the first meeting of the World Health Assembly finishing on 24 July 1948. It incorporated the Office International d'Hygiene Publique and the League of Nations Health Organization. Since its creation, WHO has been responsible for playing a leading role in the eradication of smallpox. Its current priorities include communicable diseases, in particular, HIV/AIDS, malaria and tuberculosis; the mitigation of the effects of non-communicable diseases; sexual and reproductive health, development, and aging; nutrition, food security and healthy eating; occupational health; substance abuse; and drive the development of reporting, publications, and networking. WHO is responsible for the World Health Report, a leading international publication on health, the worldwide World Health Survey, and World Health Day (7th-April of every Year). Its links with the International Atomic Energy Agency and distribution of contraception have both proved controversial, as have guidelines on healthy eating and the 2009 flu pandemic.
