BEIJING, Dec. 25 -- Youth who study just a short walk from a
fast-food outlet eat fewer fruit and vegetables, drink more soda and are more
likely to be obese than students at other schools, according to research
published Tuesday.
The study, which involved more than 500,000 adolescents at middle schools
and high schools in California, lends new fuel to a growing backlash against the
fast-food industry as studies suggest they contribute to the rising obesity
epidemic in the United States.
"We've basically discovered that kids who are going to a school that is
near a fast-food restaurant have a higher chance of being overweight and obese
than kids who are at a school that is not near a fast-food restaurant," said
Brennan Davis of Azusa Pacific University in California, whose study appears in
the American Journal of Public Health.
U.S. youth obesity rates have tripled since 1980, although they leveled off
this decade. The government says 32 percent of U.S. children are overweight and
16 percent are obese.
Consumer groups have pushed for laws such as July's moratorium on new
fast-food restaurants in certain Los Angeles neighborhoods, while the food
industry often maintains that a lack of exercise is more to blame.
The researchers said it is not yet clear whether their results apply to
other parts of the United States, and this should be studied further.
But their study adds to prior research showing that fast-food restaurants
tend to be clustered near schools.
"We are actually making a connection between fast food proximity to schools
and obesity," Davis said in a telephone interview.
"Students who were exposed to nearby fast food have a higher level of body
mass index -- they weigh more. They are more likely to be overweight and obese,"
he said.
For the study, Davis and colleagues examined the relationship between
fast-food restaurants located within one half mile of schools and obesity among
middle and high school students in California.
They took weight and dietary information from a statewide school survey
between 2002 and 2005 and cross referenced the data with a database of top fast
food chains located near each school.
"Overall, our patterns are consistent with the idea that fast food near
schools affects students' eating habits, overweight and obesity," Davis and
colleagues wrote.
They also found that students whose schools were located near-fast food
restaurants eat fewer servings of vegetables and fruits, and drink far more soda
than students at schools not located near fast-food restaurants.
The study could not determine why fast-food restaurants near schools have
such an impact, but Davis said it likely goes well beyond access to burgers,
fries and tacos.
"A nearby fast-food restaurant is really a hangout place for people to
socialize," Davis said.
