About 30 percent of reproductive-age women in the U.S. are currently classified as obese. And with obesity rates on the rise nationally, monitoring and understanding healthy weight gain during pregnancy has become a real concern for healthcare professionals.
Dangers abound for women who are obese and pregnant, including miscarriages, birth injuries, and a chance of having gestational diabetes, among other issues for the child down the road, TIME reports.
But research just out from the journal Obesity has promising news. The study found that the risk level can be lowered if women join in a program that encourages them to adopt a healthier lifestyle.
The study followed 114 women who were classified as obese, based on the Institute of Medicine guidelines. A test group was given an “intervention program,” which included individualized calorie goals, advice to follow the Dietary Approaches to Stop Hypertension dietary pattern without sodium restriction, and attended weekly group meetings, while the control group was only given advice one-time dietary advice.
And the results? Women who participated in the intervention programs gained less weight than their counterparts and their babies also had lower numbers of large-for-gestational age weights.
“Most interventions to limit weight gain among obese women during pregnancy have failed, but our study shows that with regular contact and support, these women can limit the amount of weight they gain, which will also reduce the risk of complications during and after pregnancy,” author Kim Vesco, MD, MPH, a practicing obstetrician/gynecologist, said in a press release.
Not sure what a healthy weight range is for you during pregnancy? Take a look at our general guidelines. But remember, you should always ask your healthcare provider about what’s best for you and your baby.

The obesity rate among American kids may actually be higher than the 18 percent of children the Centers for Disease Control currently classifies as obese, according to an analysis published in the journal Pediatric Obesity. As many as 25 percent of obese or overweight kids may not be counted because the tally is based on the body mass index (BMI), a calculation that researchers say is flawed because children’s height and weight change rapidly as they grow–and not always in proportion with each other.
More from The Wall Street Journal:
“BMI is not capturing everybody who needs to be labeled as obese,” said Francisco Lopez-Jimenez, director of preventive cardiology at the Mayo Clinic in Rochester, Minn., who headed the study with Asma Javed, a pediatric endocrinology fellow.
Measuring body-mass index is a relatively easy and inexpensive way to screen for obesity among large groups of people, such as children in a school setting. A problem is that BMI, a calculation based on a person’s height and weight, isn’t well suited to children because their height and weight don’t proportionally increase as they grow, said Ruth Loos, a professor of preventive medicine at the Icahn School of Medicine at Mount Sinai in New York, who wasn’t involved with the Mayo study.
“It doesn’t mean that we cannot use BMI in childhood but it requires extra caution,” she said.
Other recent research has linked everything from sleep deprivation to weight-based name calling with an elevated risk of childhood obesity. Research released earlier this year had claimed a significant drop in the childhood obesity rate in the U.S., but subsequent research actually showed a sharp increase in the number of severely obese kids.

A boy who is diagnosed during childhood with attention deficit hyperactivity disorder (ADHD) has a greater risk of developing obesity as an adult, twice the risk of a child without ADHD, according to a new study published in the journal Pediatrics. The findings are, at first glance, counter-intuitive because children with ADHD are known for being active–overly so. But the study identifies a number of factors that contribute to the elevated obesity risk. More from NBC News:
These findings, published in Pediatrics, may be surprising to parents because drugs such as Ritalin or Adderall used to treat ADHD can suppress appetite, said Dr. F. Xavier Castellanos, the study co-author and a professor of child and adolescent psychiatry at New York University.
“It’s not uncommon for kids treated with ADHD medications to be fairly thin,” Castellanos said. Because parents often worry that thinner boys won’t grow as tall, “sometimes [they] will encourage their boys to eat more.”
Instead, to help avert weight problems down the road, parents should be alert to poor eating habits. “If anything, you have to pay attention to how many times they’re having fast food, how many times they’re having fried food, whether they’re getting meals supersized,” Castellanos said.
The study comes at a time when ADHD rates are rising. A new report from the Centers for Disease Control and Prevention found that ADHD is the most common mental health issue in children ages 3-17, with nearly 7 percent of kids receiving a diagnosis.
The NYU researchers followed 222 boys — 111 with ADHD and 111 without, for an average of 33 years — hoping to better understand the disorder’s effects on the brain. The boys with ADHD, all from middle-class, white families, were diagnosed between the ages of 6 and 12.
Decades later, when some of the men returned for brain scans, many of the now 40-something adults who had ADHD as children had gained so much weight they barely fit into the fMRI machine, Castellanos said.

Telling children to “clean their plates” or finish all of their food at any given meal is associated with a higher risk of obesity later in life by a study published this week in the journal Pediatrics. More from CNN.com:
Denying certain foods to children or pressuring them to eat every bit of a meal are common practices among many parents. But researchers at the University of Minnesota found parents who restricted foods were more likely to have overweight or obese children. And while those who pressured children to eat all of their meals mostly had children of normal weight, it adversely affected the way those children ate as they grew older, according to the study published Monday in the journal Pediatrics.
Investigators combined data from two separate research studies. The first, EAT 2010 (Eating and Activity in Teens), studied around 2,800 middle and high school students from public schools in Minneapolis and St. Paul, Minnesota. Participants in the project responded to survey questionnaires designed to examine dietary intake and weight status.
Researchers combined that data with information from the Project F-EAT (Families and Eating and Activity Among Teens), a study designed to examine factors within the family environment on weight in adolescents.
From the combined information, researchers were able to gain a better understanding of how parents’ approach to food and feeding is related to adolescents’ weight. According to the Centers for Disease Control and Prevention, obesity now affects 17% of all children and adolescents in the United States – triple the rate from just a generation ago.
“We found that between 50 and 60% of parents from our sample reported requiring that their child eat all of the food on their plate at a meal,” said researcher Katie Loth, the study’s lead author. “Further, we found that between 30-40% of parents from within our sample reported encouraging their child to continue eating even after their child stated that they were full.
“While these pressure-to-eat behaviors were more frequent among parents of non-overweight adolescents, they were still endorsed quite frequently by parents of overweight and obese adolescents, indicating that many parents endorse these behaviors regardless of their child’s current weight status,” she said.

A modestly lower number of children from low-income families are clinically obese, a new report from the Centers for Disease Control and Prevention says. Recently, the Robert Wood Johnson Foundation released a study finding declines in childhood obesity rates in some major U.S. cities. More on this week’s report from The New York Times:
The study, by researchers from the Centers for Disease Control and Prevention, drew on the height and weight measurements of 27 million children who were part of the federal Women, Infants and Children program, which provides food subsidies to low-income mothers and their children up to the age of 5.
The study was based on data from 30 states and the District of Columbia and covered the years from 1998 to 2010. The share of children who were obese declined to 14.9 percent in 2010, down from 15.2 percent in 2003, after rising between 1998 and 2003. Extreme obesity also declined, dropping to 2.07 percent in 2010 from 2.22 percent in 2003. The study was published Tuesday in The Journal of the American Medical Association.
The report defined a 3-year-old boy of average height, almost 3 feet 2 inches tall, as being obese when he weighed 37 pounds or more. The same boy was categorized as being extremely obese when he weighed 44 pounds or more.
“The declines we’re presenting here are pretty modest, but it is a change in direction,” said Heidi M. Blanck, one of the study’s authors and the acting director of the Division of Nutrition, Physical Activity and Obesity at the disease centers. “We were going up before. And this data shows we’re going down. For us, that’s pretty exciting.”
