Preventing Hiv/Aids in Young People a Systematic Review of the Evidence from Developing Countries

92-4-120938-0_FM_a The World Health Organization was established in 1948 as a specialized agency of the United Nations serving as the directing and coordinating authority for international health matters and public health. One of WHO’s constitutional functions is to provide objective and reliable information and advice in the field of human health, a responsibility that it fulfils in part through its extensive programme of publications. The Organization seeks through its publications to support national health strategies and address the most pressing public health concerns of populations around the world. To respond to the needs of Member States at all levels of development, WHO pub- lishes practical manuals, handbooks and training material for specific categories of health workers; internationally applicable guidelines and standards; reviews and anal- yses of health policies, programmes and research; and state-of-the-art consensus reports that offer technical advice and recommendations for decision-makers. These books are closely tied to the Organization’s priority activities, encompassing disease prevention and control, the development of equitable health systems based on pri- mary health care, and health promotion for individuals and communities. Progress towards better health for all also demands the global dissemination and exchange of information that draws on the knowledge and experience of all WHO’s Member countries and the collaboration of world leaders in public health and the biomedical sciences. To ensure the widest possible availability of authoritative information and guidance on health matters, WHO secures the broad international distribution of its publications and encourages their translation and adaptation. By helping to promote and protect health and prevent and control disease throughout the world, WHO’s books contribute to achieving the Organization’s principal objective — the attainment by all people of the highest possible level of health. The WHO Technical Report Series makes available the findings of various international groups of experts that provide WHO with the latest scientific and technical advice on a broad range of medical and public health subjects. Members of such expert groups serve without remuneration in their personal capacities rather than as representatives of governments or other bodies; their views do not necessarily reflect the decisions or the stated policy of WHO. An annual subscription to this series, comprising about six such reports, costs CHF 168.00/US$ 106.00 (CHF 128.40/ US$ 115.00 in developing countries).

Introduction and rationale Bruce Dick,a Jane Ferguson,a & David A. Rossb 1.1 Background In 1995, WHO in collaboration with UNFPA and UNICEF convened a study group on programming for adolescent health and development. One of the products of this group was a joint technical report publication on Program- ming for adolescent health and development (1). The report synthesized the evidence for the effectiveness of interventions for adolescent health and development, and it set the direction and provided the conceptual framework for much of the programming for young people’s health and development that has taken place since its publication (2–6). The challenges posed by HIV have progressed inexorably during the past decade, especially for young people in developing countries. (Young people are defined in this report as those aged 10–24 years; this group combines adolescents – aged 10–19 years – and youth – aged 15–24 years). At the same time, many lessons have been learnt about developing and implementing programmes for young people’s health and development, including programmes to prevent the spread of HIV.
