Teen birth rates are high in the border region, an area that crosses four U.S. states, according to a recent article published by the Centers for Disease Control and Prevention.

Researchers examined birth certificates for infants born in 2009 to Mexican mothers and U.S. Hispanic women near the U.S.-Mexico border.

Jill McDonald, a professor at New Mexico State University and former CDC epidemiologist, was the lead author on the report.

McDonald said the research shows women in this border region receive less prenatal care compared to other mothers in both countries. The study also found low birth weight and early-term births were more prevalent on the U.S. border than the Mexican border.

“We’ll I think that we need to pay more attention to reproductive health problems here in the border region," she said. "It’s difficult to know how to exactly go about that, but I think the first step would be to explore the problem a little more and then start to think about intervention strategies."

The report also found Arizona Hispanic women in the border region have a higher percentage of preterm and early term births compared to U.S. Hispanic women overall.
