[Editorial] The next phase for adolescent health: from talk to action (Lancet)

Close to 1000 delegates from more than 65 countries are expected in New Delhi, India, on Oct 27-29, for the 11th World Congress of the International Association for Adolescent Health--a doubling of participants compared with the last conference 4 years ago. In addition, many more representatives are from low-income and middle-income countries (LMICs), and 125 youth delegates are attending, as are many more UN agencies and international non-governmental organisations, who have discovered adolescents as an important new group to focus on.
