School Lunches Linked to Kids' Obesity
Study Shows Kids Who Bring Lunch From Home Are Less Likely to Be Overweight
March 15, 2010 (Atlanta) -- Attention, parents! More than one in three
middle school students who regularly eat school lunches are obese or
overweight. They're also more likely to have high LDL "bad" cholesterol levels
than kids who bring lunch from home.
The research suggests that efforts to provide healthier choices on school lunch
menus still have a long way to go, says Elizabeth Jackson, MD, MPH, assistant
professor of internal medicine at the University of Michigan Health System in
"The school environment is an excellent opportunity we should not be missing
to teach kids to make healthy choices, both in terms of food and exercise," she
That's particularly important in middle school, as that's when children
start to become more independent, Jackson says. The choices they make then will
shape their eating and exercise habits as they get older, she says.
The study involved 1,076 middle school students who filled out
questionnaires asking what they ate, how much physical activity they got, and
the number of hours they watched TV, played video games, and spent on the
computer each day.
Then they were divided into three groups, depending on whether they said
they "always" or "almost always" ate school lunches, "always" or "almost
always" brought their midday meal from home, or sometimes did one and sometimes
The findings were presented at the annual meeting of the American College of
School Lunch vs. Lunch From Home
Compared with kids who brought lunch from home, those who ate school
- Were more likely to be overweight or obese (38.2% vs. 24.7%)
- Were more likely to eat two or more servings of fatty meats like fried
chicken or hot dogs daily (6.2% vs. 1.6%)
- Were more likely to have two or more sugary drinks a day (19% vs.
- Were less likely to eat at least two servings of fruits a day (32.6% vs.
- Were less likely to eat at least two servings of vegetables a day (39.9%
- Had higher levels of LDL "bad" cholesterol
The school-lunch kids also were less likely to participate in active sports
like basketball, moderate exercise like walking, or team sports than their
home-fed counterparts. And they spent more time watching TV, playing video
games, and using computers outside of school.
"One-third of kids in the U.S. are now overweight or obese, which means
one-third of kids are at risk of heart disease and diabetes as they age. That
scares me," Jackson says.
"If we don't do something now, the recent trend toward fewer deaths due to
heart disease among U.S. adults is in jeopardy of reversing, she says.
