Telling children to "clean their plates" or finish all of their food at any given meal is associated with a higher risk of obesity later in life by a study published this week in the journal Pediatrics. More from CNN.com:
Denying certain foods to children or pressuring them to eat every bit of a meal are common practices among many parents. But researchers at the University of Minnesota found parents who restricted foods were more likely to have overweight or obese children. And while those who pressured children to eat all of their meals mostly had children of normal weight, it adversely affected the way those children ate as they grew older, according to the study published Monday in the journal Pediatrics.
Investigators combined data from two separate research studies. The first, EAT 2010 (Eating and Activity in Teens), studied around 2,800 middle and high school students from public schools in Minneapolis and St. Paul, Minnesota. Participants in the project responded to survey questionnaires designed to examine dietary intake and weight status.
Researchers combined that data with information from the Project F-EAT (Families and Eating and Activity Among Teens), a study designed to examine factors within the family environment on weight in adolescents.
From the combined information, researchers were able to gain a better understanding of how parents' approach to food and feeding is related to adolescents' weight. According to the Centers for Disease Control and Prevention, obesity now affects 17% of all children and adolescents in the United States - triple the rate from just a generation ago.
"We found that between 50 and 60% of parents from our sample reported requiring that their child eat all of the food on their plate at a meal," said researcher Katie Loth, the study's lead author. "Further, we found that between 30-40% of parents from within our sample reported encouraging their child to continue eating even after their child stated that they were full.
"While these pressure-to-eat behaviors were more frequent among parents of non-overweight adolescents, they were still endorsed quite frequently by parents of overweight and obese adolescents, indicating that many parents endorse these behaviors regardless of their child's current weight status," she said.
