Teen Anger May Add Up to Extra Pounds
Overweight Kids Develop Unhealthy Ways of Dealing With Emotions, Says Researcher
March 5, 2004 -- From Rebel Without a Cause to The OC,teens have never had an easy time with anger management, but now a new study suggests that anger may "feed" teenage appetites and increase risk of obesity.
Researchers from the University of Texas Health Science Center at Houston report that problems expressing anger set teens up for a lifetime of weight problems.
In a prepared statement, William H. Mueller, PhD, who is lead researcher of the study, says, "Overweight kids have poor health behaviors, including anger expression, which may lead to increased weight, especially in girls." The research was presented at the American Heart Association's 44th annual Conference on Cardiovascular Disease Epidemiology and Prevention.
The Link Between Anger and BMI
American Heart Association spokeswoman Julia Steinberger, MD, MS, associate professor of pediatric cardiology at the University of Minnesota in Minneapolis, tells WebMD that the study is interesting but doubts it makes a strong enough case to suggest that anger management is the key to lifelong weight control.
"Just because they are finding an association doesn't mean that anger is the cause of the obesity. I don't mean to belittle the importance of psychological variables, but I have a hard time saying this [anger] is clearly what links cardiovascular disease and BMI." BMI, or body mass index, is an indicator of body fat.
The Texas researchers have been studying anger and teens since the mid-1990s when a small study suggested a link between obesity and anger.
Mueller and colleagues followed a group of 160 teens aged 14 to 17 for three years. Researchers measured BMI at the start of and during the study. The teenagers also completed an anger evaluation questionnaire to gauge anger levels, which measured "anger in," "anger out," "anger control," and "anger expression."
"Anger in" is not expressing feelings out of fear of what other people will think, Mueller says. "Anger out" is yelling, slamming doors, and other aggressive behaviors. The "anger control" score measured the level of maturity and healthy expression of feelings. The "anger expression" score factored in all of the scores -- increasing with higher "anger in" and "anger out" scores and decreasing with higher a "anger control" score.
