To investigate the accuracy of parental perceptions of their child's weight status and also the relationship between parental perceptions and the prevalence of childhood obesity in Mississippi.

Methods: Data from multi-year surveys (2009-2012) with random samples of public school parents (N=14,808). Descriptive statistics and multiple logistic regression were conducted with quantitative data to examine the relationship between parental perception and childhood obesity.

Results: More than 2 out of 5 parents misperceived the weight status of their child (k-12). The greatest difference occurred with kindergartners, 83.9% of parents categorized them as "healthy", when only 28.3% actually were. Parents who misperceived their child's weight were almost 12 times more likely of having an obese child.

Conclusions: Only half of the children in this study had a healthy weight (54.5%). Health care providers, nutritionists, social workers, teachers, and school health councils could play an important role in educating parents and children on how to recognize an unhealthy weight. Conclusions: The strongest predictor of childhood obesity was parental misperception of their child's weight status.
