This is the VOA Special English Health Report.
Premature or preterm births are defined as live births before a woman completes 37 weeks of pregnancy. A new study found that about 15 million babies were born prematurely around the world in 2010. The study was the first of its kind, and shows that the problem exists in poor countries as well as in wealthy ones.
Researchers gathered information from 84 countries. The researchers were from Save the Children, a nongovernmental organization. They found that more than one in ten babies are born too soon.
The research team found that 15 countries -- including the United States and Brazil -- had two-thirds of all preterm births. Sixty percent of preterm births happen in South Asia and sub-Saharan Africa.
Problems related to premature birth are the second most common cause of death in children under five, after pneumonia. The study found that these complications of preterm birth result in more than a million deaths around the world every year.
Babies born early are more likely to develop learning disabilities and problems with their eyesight and hearing. They can also suffer cerebral palsy, a neurological condition, and a lifetime of lung disease. The risk of death in a newborn also increases sharply if babies are born after less than 32 weeks of pregnancy.
But eight out of ten premature babies are born between 32 and 37 weeks. Joy Lawn of Save the Children in South Africa led the team that wrote the report for the World Health Organization. She says with the right medical care and loving attention, these newborns have a good chance of survival.
JOY LAWN: "They would survive with really basic care. So, being breastfed, being kept warm. And they are at much higher risk of infection, so treating with antibiotics."
She says only five percent of preterm babies were born at 28 weeks or less. Those that survived birth required intensive hospital care.
The research team found that only three countries -- Croatia, Ecuador and Estonia -- had a decrease in their preterm birth rates between 1990 and 2010.
JOY LAWN: "Really we can't point to one solution and say this is what caused it. Just as we couldn't point to something in the US and say this is what caused the very high rates in the US."
In the United States, 12 percent of all live births in 2010 were preterm.

This study would have interested Mary Ellen Avery. She was a medical researcher who made a discovery that helped save the lives of many preemies. Next week, learn about Dr. Avery and her discovery more than 50 years ago.
