Problems Feed Childhood Obesity
Study finds overweight kids twice as likely to misbehave.

If your child is
antisocial, anxious, dependent, depressed, headstrong,
hyperactive or withdrawn, the likelihood of his or her becoming
obese is greatly increased, a new study says.
"We found that children who are overweight are twice as likely
to have behavioral problems compared with children who don't
have behavioral problems," says study author Dr. Julie Lumeng, a
researcher investigator at the University of Michigan.
Most obese children do not have behavior problems, Lumeng says.
But behavior problems seem to be one cause of obesity, she adds.
The research team was curious if behavior problems start before
children become overweight, and if they contribute to becoming
overweight. "We found that normal weight children who have
significant behavior problems are five times more likely to
become overweight over the following two years," Lumeng says.
In their study, reported in the November issue of Pediatrics,
Lumeng's team collected data on 755 children, aged 8 to 11. The
parents of these children completed a questionnaire that asked
about their child's behavior.
"The mind and the body are so interrelated that you cannot
ignore a child's mental health," Lumeng says. "If we as a
country are trying to stem the tide of obesity in children, we
really have to look at the root of what is triggering children's
behavior leading to obesity."
Lumeng believes that to lessen the chance of becoming obese,
behavior problems need to be recognized and treated.
Lumeng says the reasons why behavior problems lead to obesity
remain unknown. "It could be that these children don't go
outside and play as much as other children, or maybe they spend
too much time watching TV, or maybe they are using food to make
themselves feel happier."
Parents who have a child who shows significant behavior problems
should see their pediatrician and get the child into therapy,
Pediatricians need to investigate the behavior problems of their
normal weight patients and get them help. They also need to be
aware of behavioral problems among their patients who are
already obese, she adds.
One of the goals in dealing with behavior problems is to prevent
children from becoming overweight, Lumeng notes. "If you can
treat the behavior problems, hopefully, you can prevent the
progression to obesity."
Lumeng says the epidemic of obesity in the United States, of
which the child with behavior problems is a small piece, is a
result of the ever-increasing ease that has become a hallmark of
In addition, she says food in restaurants is being super-sized
and food is so much more accessible. "These are the reasons that
the average American child is becoming obese today," she says.
David Katz, an associate clinical professor of public health at
Yale University, comments that "it comes as no great surprise
that behavioral problems in childhood increase the risk of
weight gain over time and obesity."
"Restrained eating in our 'toxic' nutritional environment is
difficult for all and it's much more difficult for those with
emotional and behavioral difficulties," he adds.
Katz agrees with Lumeng that physical activity is likely to
suffer in children with significant emotional and behavioral
problems who cannot "simply go out to play with friends."
In addition, he notes American parents have difficulty
cultivating healthful eating habits in even the most emotionally
balanced children. Children with emotional and behavioral
problems are much more of a challenge, Katz adds.
"While this research is valid and interesting, its importance
should not be over-interpreted," Katz says. "The critical
message of our day is that all children are at increasing risk
of obesity. Currently, nearly 80 percent of adults are
overweight, and the rates of childhood obesity are rising
If something is not done, there will be a generation of adults
in whom the prevalence of obesity is nearly 100 percent, he
says. "This is the big picture, the crisis at hand, and the
take-away message for anyone concerned about childhood obesity."
