(CNN) - Ask any parent, their children are pretty much perfect in their eyes. But that's the problem, the love that parents have for their children could be blinding them from seeing a growing problem.
A study from the University of Nebraska-Lincoln found that some parents are overlooking their kids' obesity.
The researchers analyzed 20 years of data from nearly seventy studies of children ages 2 to 18-years-old.
Researchers found more than 50 percent of parents underestimated the weight of their overweight or obese child.
This has important implications for kids and parents.
"What you don't know can hurt you. If parents don't know that their children have a weight problem, then they may not take the steps to make appropriate lifestyle changes, and get the support that they need. And there can be real long term health implications," said Timothy Nelson, assistant professor of psychology at the University of Nebraska-Lincoln, who helped conduct the study.
The study found the younger the kids are, the more parents overlooked weight concerns. After the child reaches 5-years-old, parents' perceptions of their children became more accurate.
And there is a gender divide. Parents are more accurate in judging the size of their daughters than sons.
And while no one believes parents should be overly critical of their children, especially when it comes to body image, this is a matter of health. The childhood obesity rate is three times what it was 30 years ago in our country.
