Chapter 2: Literature Review The conceptual framework for this research is based on studies conducted over periods of 6 months to 6 years, the strength of evidence is high that school-based diet and physical activity interventions with a home component or school based combination interventions with a home component prevent obesity or overweight (Wang, 2005). The strength of evidence is moderate that school-based interventions contribute to obesity prevention (Sharma, 2012). The strength of evidence is moderate that school-based diet or physical activity interventions with either home components using a combination intervention contribute to obesity prevention.

The increasing proportion of young people failing into this category is taking on the characteristics of a pandemic and as such is triggering discussion and action in an effort to reverse obesity trends. The role of various stakeholders in these efforts have been explicated by the literature. According to the CDC (2014), there has been significant research completed on how parents, teachers and the external school environment impact the dietary habits of young people. However, although there has been a great deal of focus on steps that these groups can take to improve the eating habits of young people, there is a lack of integrative work examining potential mediating cognitive mechanisms in parental involvement as it relates to school programs. In the following section, the research in these areas is examined and
