Fast food not the major cause of rising childhood obesity rates
Date:1/15/2014

For several years, many have been quick to attribute rising fast-food consumption as the major factor causing rapid increases in childhood obesity. Now researchers at the University of North Carolina at Chapel Hill report that fast-food consumption is simply a byproduct of a much bigger problem: poor all-day-long dietary habits that originate in children's homes.

The study, led by Barry Popkin, W.R. Kenan Jr. Distinguished Professor of nutrition at UNC's Gillings School of Global Public Health, found that children's consumption of fast food is only a small part of a much more pervasive dietary pattern that is fostered at an early age by children's parents and caregivers. The pattern includes few fruits and vegetables, relying instead on high amounts of processed food and sugar-sweetened beverages. These food choices also are reinforced in the meals students are offered at school.

"This is really what is driving children's obesity," said Popkin, whose work appears in The American Journal of Clinical Nutrition. "Eating fast foods is just one behavior that results from those bad habits. Just because children who eat more fast food are the most likely to become obese does not prove that calories from fast foods bear the brunt of the blame."

The study looked at data acquired through the National Health and Nutrition Examination Survey between 2007 and 2010. The researchers studied the dietary intake of 4,466 children between 2 and 18 years old and whether they ate at fast-food establishments or elsewhere. The children were further categorized as being nonconsumers of fast food (50 percent of the children), low consumers (less than or equal to 30 percent of calories from fast foods; 40 percent of the children) or high consumers (more than 30 percent of calories from fast foods; 10 percent of the children). The researchers then determined which factors were most related to dietary adequacy and risk for obesity.
