Among the multiple factors that can cause obesity is an abnormal neurocognitive or behavioral response to food cues. The brain becomes wired to seek and expect greater rewards from food, which leads to unhealthful overeating.
Attention modification programs, which train a person to ignore or disregard specific, problematic cues or triggers, have been used effectively to treat cases of anxiety and substance abuse. In a novel study published this week in the journal Appetite, Kerri Boutelle, PhD, professor of pediatrics and psychiatry at the University of California, San Diego School of Medicine, and colleagues report using a single session of attention modification to decrease overeating in obese children.
"Attentional bias is a long-studied psychological phenomenon," said Boutelle. "Attentional bias to food means that food grabs a person's attention. If two people were in a room with potato chips on the table, the person with attentional bias would be paying attention to, maybe looking at, the chips and the person without the bias would not really notice or pay attention to them.
"We believe that there is a group of people who are inherently sensitive to food cues and, over time, eating in response to paying attention to food makes them pay even more attention. It's based on Pavlovian conditioning."
Obesity in the United States is a well-documented problem, with more than a third of American adults considered to be obese. Child obesity is equally alarming, with an estimated one-third of American children (4 to 5 million individuals) overweight or obese. These children are at greater risk for cardiovascular disease, cancer, orthopedic and endocrine conditions and more likely to die earlier.
Boutelle and colleagues investigated whether attention modification training might be another way to treat problematic eating and obesity in children. In a novel pilot study, they recruited 24 overweight and obese chi
