The pervasiveness of obesity and obesity-related disease among children living in the United States is causing increasing attention. In the past two decades, childhood obesity has more than doubled in children aged six to 11, rising from 6.5% in 1980 to 17.6% in 2006. Obesity among adolescents between the ages of 12 and 19 has more than tripled from 6.5% to 17.6% within the same period (Li, & Hooker, 2010).
The increased prevalence of childhood obesity creates many reasons for concern. Many obese children suffer from physical and psychological effects. In addition, childhood obesity can adversely affect social and economic development and lead to adult obesity causing more adverse health conditions. The costs of treating obesity in the United States are steadily increasing. Estimates show the direct and indirect costs associated with treating obesity was near $139 billion in 2003 (Li, & Hooker, 2010). The focus of this paper is to examine a peer-reviewed research article conducted by Ji Li, PhD. and Neal Hooker PhD published in the Journal of School Health, to show how the application of background and methodology of the research process can be applied to problems in health care. By examining the purpose of the study, the hypothesis, the variables employed, and the framework used to guide the study, a better understanding of the research process will be gained.
Study Purpose Schools have been the subject of many research studies regarding childhood obesity. Surveys have examined issues such as race, ethnicity, and gender-specific differences relating to issues such as how television viewing affects weight gain and how physical activity effects academic achievement. The National School Lunch Program (NSLP) School Breakfast Program (SBP) and have been the subject of many studies (Li, & Hooker, 2010). The studies examined food choices; comparing the nutritional content of program meals to other
