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.”

The childhood obesity rate–still believed to be a nationwide epidemic–is actually dropping in some major U.S. cities, a new report by the Robert Wood Johnson Foundation has found. More from The New York Times:
“It’s been nothing but bad news for 30 years, so the fact that we have any good news is a big story,” said Dr. Thomas Farley, the health commissioner in New York City, which reported a 5.5 percent decline in the number of obese schoolchildren from 2007 to 2011.
The drops are small, just 5 percent here in Philadelphia and 3 percent in Los Angeles. But experts say they are significant because they offer the first indication that the obesity epidemic, one of the nation’s most intractable health problems, may actually be reversing course.
The first dips — noted in a September report by the Robert Wood Johnson Foundation — were so surprising that some researchers did not believe them.
Deanna M. Hoelscher, a researcher at the University of Texas, who in 2010 recorded one of the earliest declines — among mostly poor Hispanic fourth graders in the El Paso area — did a double-take. “We reran the numbers a couple of times,” she said. “I kept saying, ‘Will you please check that again for me?’ ”
Researchers say they are not sure what is behind the declines. They may be an early sign of a national shift that is visible only in cities that routinely measure the height and weight of schoolchildren. The decline in Los Angeles, for instance, was for fifth, seventh and ninth graders — the grades that are measured each year — between 2005 and 2010. Nor is it clear whether the drops have more to do with fewer obese children entering school or currently enrolled children losing weight. But researchers note that declines occurred in cities that have had obesity reduction policies in place for a number of years.

At 9 years old, Breanna Bond weighed 186 pounds, a number that had her doctor and her family alike worried for her health in an age of childhood obesity and rampant Type II diabetes that affects an estimated 12.5 million U.S. children. As CNN.com reports, the involvement of the whole family was the key motivating factor that helped Breanna shed 65 pounds:
“Conversations about a child’s weight can be fraught with psychological landmines, says Dr. Denise Wilfley, director of the Weight Management & Eating Disorders Program at Washington University School of Medicine.
“Mainly what we suggest is actually having the whole family take on a healthier lifestyle — for everybody to eat as well as possible, as nutritiously as possible, so the overweight child is not singled out,” she says.
Wilfley encourages parents in her programs to “walk the walk” and be a role model for their children. She talks about food as energy for kids’ bodies — eating better will help them think harder, jump higher, play more.
Her families try to follow the traffic light diet, with green-light foods such as vegetables, yellow-light foods such as lean protein and red-light foods such as sweets or simple carbohydrates.
“We focus a lot on not defining self-worth by the number on the scale,” she says. “The best way to prevent eating disorders is having very healthy eating patterns.”
[Heidi] Bond realized that in order to get [her daughter] Breanna to exercise regularly, they would had to make it a family activity. The Bonds started walking four miles, four days a week, on a trail near their home in Clovis, California.
“It was the hardest thing I’ve ever had to do,” Bond says. “There were times where she refused to move.” But in the end, “a little tough love to save the rest of their life” was worth it, she says.
It’s best to avoid a power struggle when it comes to exercise and healthy eating, according to Jelalian. She says it’s easy for parents to become the “food police” without getting at the deeper issues. Parents should ask why a child wants a certain food or doesn’t want to work out and problem-solve with them to find a healthy alternative.
She recommends parents give their kids a choice as much as possible — not about being active or not active, but about what activity they want to do.
“It really takes that balance in parenting of being firm — this part is not negotiable, but being warm, caring in how you do that.”
Identifying your child’s motivation for losing weight is key, Wilfley says. Do they want to be able to run faster? Play football? Avoid teasing at school? Combining that goal with incentives such as sleepovers or family outings should help to keep a child motivated.”
