“There is no healthcare delivery system for non-pregnant 15- to 24-year olds,” said the U.S. Global AIDS Coordinator, Ambassador Deborah Birx, at a recent Wilson Center event on efforts to reduce the prevalence of HIV/AIDS among adolescent girls in sub-Saharan Africa. In 2014, the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) established the DREAMS program, which aims to create “a health care system where young people interact in a proactive and positive way,” said Birx.

“All or most of the children living in these communities are by nature vulnerable,” said Melanie Yahner of Save the Children at a recent Wilson Center event on the sexual, reproductive, and maternal health of urban adolescents. Given that half of the global population living in urban areas today is under the age of 25, addressing the health needs of adolescents living in cities has become critical. “Who is shaping their norms and practices?” said Yahner. “How do we develop and adapt interventions that are meaningful for their needs?”

At 1.8 billion strong, the current generation of 10 to 24 year olds is the largest in human history. Approximately 90 percent of these adolescents live in less developed countries. This poses an unprecedented challenge for health systems and social policies which largely struggle to meet the unique needs of young people, according to a new Lancet commission.

“If we are serious about results, [the Sustainable Development Goals] must be developed from the perspective of the young person, particularly the adolescent girl. It is about her challenges, her rights, and her future. Our collective success begins and ends with her,” said Benoit Kalasa, director of the technical division for the United Nation’s Population Fund at the Wilson Center on October 19. [Video Below]

Adolescent boys are 75 percent more likely to die from HIV/AIDS than girls. Why? That’s unclear. Lack of data and failure to engage boys in discussions about sexual and reproductive health and HIV care has left many suffering, says Elizabeth Berard, a health science specialist with the U.S. Agency for International Development, in this week’s podcast.

In July, thousands of people attended the 20th International AIDS Conference and the 2014 Girls Summit to work towards an AIDS-free generation and ending child and forced marriage. But such attention is rare; by and large, these girls are invisible to development efforts. [Video Below]

Twenty thousand girls under the age of 18 give birth every day, and 90 percent of these births occur within the context of marriage, according to the UN Population Fund’s latest State of the World Population report. This year’s edition, launched at the Wilson Center on October 30, focuses on adolescent pregnancy and finding ways to better protect this vulnerable group of young women.
