Teen moms at greater risk for later obesity, U-M study finds

A new study debunks the myth that younger moms are more likely to “bounce back” after having a baby – teenage pregnancy actually makes women more likely to become obese.

Women who give birth as teens are significantly more likely to be overweight or obese later in life than women who were not teen moms, University of Michigan Health System researchers found.

The nationally representative study, which is the first believed to identify teen pregnancy as a predictor of obesity, appears in the American Journal of Obstetrics & Gynecology.

“When taking care of teen moms, we often have so many immediate concerns - child care, housing, school, social and financial support - that we don’t often think of the long term health effects of teen pregnancy,” says lead author Tammy Chang, M.D., MPH, MS, a clinical lecturer in the department of family medicine at the U-M Medical School and a Robert Wood Johnson Foundation Clinical Scholar.

“For the first time, we’ve identified our youngest moms as a high risk group for obesity, which we know to be one of the most debilitating, long-term health issues we face.”

The study was based on data from The National Health and Nutrition Examination Survey (NHANES), a national study designed to assess the health and nutritional status of adults and children in the United States.

Teen moms at greater risk for later OBesity

After controlling for factors such as race, education, and socio-economic indicators, researchers found that women who had first given birth between the ages 13-19 had a 32 percent higher risk of obesity than women who had given birth at age 20 or later. The findings also showed that a significantly fewer number of women with a teen birth were normal weight compared to women without a teen birth.

Teen obesity tied to poor mom-child relationship
Toddlers who have poor relationships with their moms are more likely to pack on extra pounds as they grow up, a new U.S. study shows.
Tracking nearly 1,000 kids into their teens, researchers found more than a quarter of those who scored lowest on mother-child relationship tests as toddlers went on to become obese at age 15.
By contrast, only 13 percent of the children who had a good relationship with their mother became obese.
While that doesn’t prove cause and effect, researchers say other work has shown links between children’s emotional and intellectual development and how they interact with their mothers at a young age.
According to Sarah E. Anderson, who worked on the new study, it’s possible that a stressful childhood could make a lasting impression on kids’ brains.

“We need further studies to better understand the link between teen birth and obesity, so that physicians and policymakers can provide the best care to teen mothers and women who have given birth as teenagers,” Chang says.

Teen moms at greater risk for later OBesity

Despite declines in the last two decades, teen pregnancy rates in the United States continue to be one of the highest in the developed world. Obesity rates among reproductive age women in the U.S. also remains high, with between a quarter and a third of women age 20-44 categorized as obese. Pregnancy itself is a strong risk factor for obesity.

‘We know that teen pregnancy is tied to certain immediate risks, such as babies having low birth weight and mothers struggling to complete high school – and now we know that it is also associated with poor long-term health outcomes,” says Chang.

It seems to me that both obesity and teen pregnancy are things that, society-wide, we should be doing everything in our power to prevent. From bike lanes and subsidized veggies (obesity) to sex ed and community support (teen moms), governments are completely correct to advocate that reduction of these phenomena is a societal good.

That said, the minute a teenager gets pregnant, they deserve all the resources of the state to help them raise their child. Not only for their own basic dignity, but to break the cycle of poverty and lack of opportunity that drive rates of teen pregnancy in the first place. Those kids weren’t born to teen moms from any fault of their own, and they should have every opportunity for education, health and security.

The same paradigm should govern obesity: Try really hard at the societal level to prevent obesity, but accept that being overweight is significantly easier than not being overweight, and it doesn’t make economic sense to discriminate fat people out of the workplace, healthcare or beneficial social relationships.

The problem is that this strikes most people as a complete contradiction, and is really difficult to express in the precocious-fifth-grader vocabulary our politicians speak in. We can promote and we can stigmatize, but we have no way of saying as a culture ‘you shouldn’t be here, but you are. So let’s get to work.’

“Obesity is a prevalent, expensive health problem with detrimental health consequences and it’s difficult to reverse, which is why it’s incredibly important to identify at risk groups early so that we can intervene.”
