Efficacy of a nutrition education program designed for grades K--3 piloted in Johnson County schools

The purpose of this study was to increase the nutrition knowledge of elementary school students by implementing nutrition education lessons. The subjects included 49 kindergarten through third grade students in Johnson County, Tennessee during the fall of 2004. Knowledge increase was measured by pretest and posttest scores. The tests were analyzed by paired t-tests. While all students showed an increase in mean score, kindergarten and first grade students did not show a significant increase in posttest scores. However, second and third grade students showed a significant increase in posttest scores, indicating an increase in nutrition knowledge.
