A few years can make a life-saving difference for girls who give birth in their teens.
That's according to a United Nations survey showing that girls who give birth before the age of 15 are five times more likely to die in childbirth, compared to women who gave birth in their 20s.
The director of UNICEF says 70,000 women between the ages of 15 and 19 die in childbirth or from pregnancy complications every year. The U.N.'s annual children's survey paints a bleak picture of the many health and lifestyle risks of teenage pregnancy. Teen pregnancy is especially common in developing countries.
The study also finds that teen births risk more than the mother's life. If a teen give birth under the age of 18, her baby's risk of dying in its first year is 60 percent greater.
