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.

Although exclusive breastfeeding is recommended when medically possible, a new study published in the journal Pediatrics has found that supplementing breast milk with formula will not compromise breastfeeding, and that in some cases formula may even help mothers to have successful breastfeeding experiences when their babies are losing weight. More from The New York Times:
Researchers randomly assigned 38 infants who had lost 5 percent or more of their weight in the days after birth to either breast-feeding alone (the controls), or breast-feeding along with a supplement of formula at the end of each session.
At 1 week of age, all were still breast-feeding, but 9 of 19 infants in the control group were now using formula, compared with only 2 in the group that had used formula at the start. By age 3 months, 79 percent of the early formula users were breastfeeding exclusively, compared with 42 percent of the controls.
The researchers emphasize that they used a careful procedure — small volumes of formula and careful administration with a syringe to prevent confusion between breast and bottle nipple.
“Most babies don’t need formula,” said the lead author, Dr. Valerie J. Flaherman, a pediatrician at the University of California, San
Francisco, Benioff Children’s Hospital. “But some kids are at risk for weight loss, and this could be an option.”

Teenagers with asthma have better oversight of their care from parents and doctors than young adults in their early 20s, so teens’ care is more consistent, a new study published in the journal Pediatrics has found. More from Boston.com:
Parents of teens with asthma can remind them to take medications, fill their prescriptions, and make appointments with pediatricians who probably know the child well. But a few years later, when the young adult has left home for college or to live independently, that oversight is gone — and their care can suffer.
Twenty-nine percent of young adults with asthma received treatment at an emergency room during the previous year, compared with 19 percent of younger teenagers with the condition, according to an analysis of national survey data collected between 1999 and 2009. Losing health insurance coverage is a major — but not the only — factor in this declining care, the study found.

The research, led by Dr. Kao-Ping Chua of Harvard Medical School and Boston Children’s Hospital, suggests that many young people wait for a medical crisis rather than seeking preventive care from primary care doctors they may not know well.

Doctors are increasingly making the diagnosis of “GERD,” or gastroesophageal reflux disease, in infants, and the label may be prompting parents to medicate for infant issues that pediatricians would otherwise regard as normal, such as crying and spitting up.
A new report published in the journal Pediatrics argues that the use of the disease label is leading to the growing use of medication. “Labeling an otherwise healthy infant as having a “disease” increased parents’ interest in medicating their infant when they were told that medications are ineffective,” the article concludes. “These findings suggest that use of disease labels may promote overtreatment by causing people to believe that ineffective medications are both useful and necessary.”
Previous research has already established the growing number of medical interventions for GERD. One 2010 study by the Food and Drug Administration found that the prescription rate for a particular class of acid blockers increased 11-fold in the years between 2002 and 2009 for babies under age 1.
The new study, which was conducted as a survey of parents in a general pediatric clinic, attributes the rise to the use of the disease label GERD. From the survey’s abstract, “Parents who received a GERD diagnosis were interested in medicating their infant, even when they were told that the medications are likely ineffective. However, parents not given a disease label were interested in medication only when medication effectiveness was not discussed (and hence likely assumed).”

The American Academy of Pediatrics recommends that babies be fed only formula or breast milk until they are 6 months old, but more than 90 percent of mothers are offering solid food to their babies earlier than that, with 40 percent offering solids before 4 months, according to a new study by the Centers for Disease Control and Prevention. The CDC survey, which was published in the journal Pediatrics, said the findings are “worrisome” in that babies may be at increased risk for developing chronic diseases, such as diabetes, obesity, eczema, and celiac disease. More from NBC News:
The mothers who volunteered for the CDC study filled out food diaries and questionnaires designed to ferret out their opinions on why and when solid foods should be offered.
Among the moms offering solid foods to infants younger than 4 months, the most commonly cited reasons for doing so included: “My baby was old enough;” “My baby seemed hungry;” “I wanted to feed my baby something in addition to breast milk or formula,” “My baby wanted the food I ate;” “A doctor or other health care professional said my baby should begin eating solid food;” and “It would help my baby sleep longer at night,” researchers reported.
What’s more, moms who fed their babies formula were far more likely to start solids too early versus those who exclusively breast-fed (53 percent versus 24 percent), the study showed.
One food expert unaffiliated with the CDC study suggested that some health-care providers may simply be unfamiliar with current baby-feeding recommendations.
“I think this is worrisome,” said Ann Condon-Meyers, a pediatric dietician at the University of Pittsburgh Medical Center and Children’s Hospital of Pittsburgh. “I think it may show that word isn’t getting out that … it is 6 months before solid foods should be offered.”
