Teen Births May Increase Risk of Obesity Later in Life
Having a child before age 20 linked to 32 percent greater odds of obesity, study finds

Researchers analyzed data from the U.S. National Health and Nutrition Examination Survey and found that 44 percent of women who had their first child when they were teens were obese, compared with 35 percent of those who had their first child at age 20 or later.
After adjusting for a number of factors, such as education level and race/ethnicity, the researchers determined that women who had their first child in their teens were 32 percent more likely to be obese in later adulthood than those who had their first child at age 20 or later.
The study findings were released online in advance of publication in the July print issue of the American Journal of Obstetrics and Gynecology.
"When clinicians care for teen mothers, we have so many immediate considerations -- child care, housing, school, social and financial support -- that we may fail to consider the long-term health effects of teen pregnancy," lead author Dr. Tammy Chang, a Robert Wood Johnson Foundation clinical scholar at the University of Michigan, said in a foundation news release. "What we have found in our study is that teen childbirth carries a long-term risk of obesity."
The teen birth rate in the United States is one of the highest among industrialized countries. Teenagers account for one in every 11 deliveries in the nation, according to 2010 U.S. Census data.
"These findings indicate that we need to start considering the long-term health risks of teen childbirth, as well as short-term risks, in health and policy discussions about teen pregnancy," Chang said. "And now we know that long-term risks include obesity later in adulthood."
Although the study found an association between childbirth in the teen years and greater risk of obesity later in life, it did not prove a cause-and-effect relationship.
