(May 2003) Nearly 1.7 billion people, about one-third of the world’s total population, are between the ages of 10 and 24 (United Nations 2001), with the vast majority living in developing countries. As they mature, young people are increasingly exposed to reproductive health risks such as sexually transmitted infections (STIs), unintended or early pregnancies, and complications from pregnancy and childbirth. Improving young people’s reproductive health care is key to improving the world’s future economic and social well-being. But young people’s reproductive health needs are often overlooked or viewed through a lens of cultural values that limit care. Health facilities frequently fail to provide young adults with specialized reproductive health information, counseling, and services. Lack of experience in social negotiation, ignorance about their bodies and where to seek care, social stigma, and poor treatment by providers often limit young people’s access to the services they need.
