Pregnancy jeopardizes the rights, health, education and potential of far too many adolescent girls, robbing them of a better future. Action must be taken to prevent "children having children", as we are commemorating World Population Day 2013 on Thursday, which focuses on adolescent pregnancy.

Around the world, about 16 million girls aged 15 to 19 give birth each year. In developing countries, 19 out of 100 girls give birth by the age of 18 and three give birth before the age of 15. Complications from pregnancy and childbirth are the leading cause of death among girls in this age group, especially in developing countries.

Millions of teenage girls across the world are, or will be, practicing unsafe sex, and far too many lack access to information, contraceptives and basic education in the fundamentals of sexual and reproductive health. If young people are able to receive age-appropriate and comprehensive sex education, they will develop the knowledge and skills they need to protect their health throughout their lives. If young people can access good quality youth-friendly sexual and reproductive services, they will be able to make informed choices to keep them healthy. The opportunities and choices girls have during adolescence will enable them to begin adulthood as empowered and active citizens.
