Mapping a global agenda for adolescent health.

Major changes in health are underway in many low- and middle-income countries that are likely to bring greater focus on adolescents. This commentary, based on a 2009 London meeting, considers the need for strategic information for future global initiatives in adolescent health. Current coverage of adolescent health in global data collections is patchy. There is both the need and scope to extend existing collections into the adolescent years as well as achieve greater harmonization of measures between surveys. The development of a core set of global adolescent health indicators would aid this process. Other important tasks include adapting and testing interventions in low- and middle-income countries, growing research capacity in those settings, better communication of research from those countries, and building structures to implement future global initiatives. A global agenda needs more than good data, but sound information about adolescent health and its social and environmental determinants, will be important in both advocacy and practice.
