This study examined differences in grade school students' BMI percentiles before and after the "Healthy, Hunger Free Kids Act" of 2012 and factors that may have influenced those differences. Using publically available data from the Pennsylvania Departments of Health and Education, a comparative analysis of BMI percentiles, ethnicity, gender, student enrollment, free or reduced lunch eligibility, and total school lunch sales for school years 2008-2009 and 2012-2013 was conducted. A combination of Chi Square and T Tests analyses revealed a significant difference in BMI measures, the number of students within ethnic categories, and total lunch sales; and no significant differences in the number of students within each gender category, free or reduced lunch eligibility, or student enrollment between the two study years. These findings suggested that the "Healthy, Hunger Free Kids Act" of 2012 was successful in reducing student obesity statistics.
