Feb. 8, 2010 -- Simple lifestyle habits at home, such as having more family
meals, could reduce obesity in preschoolers, new research suggests.
A study to be published in the March issue of the journal Pediatrics
says preschoolers could reduce their risk of obesity by nearly 40% if they ate
more evening meals as a family, limited their time watching TV, and got
Taking one or more of the three actions would likely lower obesity risk in
that age group, says Sarah Anderson, PhD, lead author of the study and an
assistant professor of epidemiology at Ohio State University.
Four-year-olds living in homes that followed all three of those lifestyle
routines had an almost 40% lower prevalence of obesity than children in homes
that didn’t practice any, the researchers report. The findings took into
account risk factors such as maternal obesity and household income.
Anderson and colleague Robert Whitaker, MD, professor of public health and
pediatrics at Temple University, analyzed data on 8,550 4-year-old U.S.
children in 2005. Eighteen percent of the children were determined to be
The odds of obesity in children who were exposed to all three household
routines was 37% less than in children who were exposed to none.
“The routines were protective even among groups that typically have a high
risk for obesity,” Anderson says in a news release. “This is important because
it suggests that there’s a potential for these routines to be useful targets
for obesity prevention in all children.”
The information on the children came from the Early Childhood Longitudinal
Study, Birth Cohort, a study conducted by the National Center for Education
Statistics that’s aimed at finding information about health and healthy
learning environments in children.
The researchers defined the three healthy routines as eating the evening
meal as a family more than five times per week, getting at least 10.5 hours of
sleep nightly, and watching less than two hours of TV on weekdays.
The researchers say adopting just one of the practices could lower a child’s
risk of becoming obese. Each routine was linked with 23%-25% lower odds of
“I imagine people are going to want to know which of the routines is most
important,” Anderson says. “Is it limited TV, is it dinner, is it adequate
But she says the research doesn’t answer that question.
“Each one appears to be associated with a lower risk of obesity, and having
more of these routines appears to lower the risk further,” she says in the
