This article examines whether the percentage of children with high body mass index varied between 2003 and 2006. While the prevalence of childhood obesity has increased since the 1980s, this research can provide a better understanding of recent trends in childhood obesity.
The authors analyzed data from 8,165 children who completed the National Health and Nutrition Examination Survey between 2003 and 2006. Height and weight measurements were used to calculate the prevalence of Body Mass Index (BMI) above the 85th, 95th and 97th percentiles of Centers for Disease Control and Prevention (CDC) BMI-for-age growth charts.
Although rates of overweight have increased for children in the past two decades, there was no statistically significant change in the prevalence of high BMI between 2003 and 2006.
