“Low prices, convenience, and free toys target the middle class—especially budget-conscious, hurried parents—very well," Leigh said.
As earnings increase from low to middle class, so does the frequency of fast-food dining, weakening the argument that fast food can be blamed for higher rates of obesity among the poor.
“There is a correlation between obesity and lower income, but it cannot be solely attributed to restaurant choice,” says J. Paul Leigh, professor of public health sciences at University of California, Davis. “Fast-food dining is most popular among the middle class, who are less likely to be obese.”
For a new study, published online in Population Health Management, Leigh and co-author DaeHwan Kim used data from the 1994 to 1996 Continuing Survey of Food Intakes by Individuals and the accompanying Diet and Health Knowledge Survey.
The nationally representative sample of nearly 5,000 people in the U.S. included data about food consumption patterns, including restaurant visits over two nonconsecutive days, which was compared with demographic variables such as household income, race, gender, age and education.
