Health Behaviour in School-aged Children (HBSC), a WHO collaborative cross-national study, has provided information about the health, well-being, social environment and health behaviour of 11-, 13- and 15-year-old boys and girls for over 30 years.

The document summarizes priority areas for WHO action based on global evidence. Improving the health and development of children and adolescents means that WHO will need to shape its implementation of the strategy to the epidemiological needs of specific regions and countries.

This booklet examines the impact of HIV/AIDS on young people, looking at why they are being hit by the epidemic. It puts forward some ideas for HIV/AIDS prevention education and lists some principles for working with young people.
