Overweight and Obesity Prevalence and Trends Among Mississippi Public School Students: A Decade of Data Between 2005 and 2015.

This study estimated. the prevalence of overweight and obesity in Mississippi public school students in grades K-12 and examined changes between 2005 and 2015. In 2015, the prevalence of overweight, obesity, and both combined remained higher than national averages, yet the rates have neither increased nor decreased significantly since 2005 (p = 0.6904). In 2015, as with all previous years, there was no difference between boys and girls (p=0.570). As in all previous years, the prevalence of obesity in 2015 was significantly higher among black students (p < 0.001) than among white students. Similar to 2011 and 2013, there was a significant difference by grade level in 2015 (p=0.0029), with the lowest prevalence again among the elementary students. The significant linear decrease in obesity prevalence among elementary school students observed during 2013 continued to 2015 (p = 0.0209). Trends are discussed in the context of state policy and recent research.
