Overweight and Obesity among Children: An Evaluation of a Walking Program.

The purpose of this study was to identify the prevalence of overweight and obesity among 5,158 school-age children and to evaluate the effectiveness of a walking program to encourage physical activity among children in Western Pennsylvania. According to the National Health and Nutrition Examination Survey (NHANES), obesity in school-age children affects approximately 19% of children 6-11 years old in the United States (Centers for Disease Control and Prevention 2010c ). Data were collected over six years. The results of the study revealed the prevalence of obesity and overweight was higher than the national averages: 36% versus 20%. The results also revealed the walking program to be beneficial in reducing students' prevalence of obesity and overweight and keeping them moving.
