Calcium is an essential mineral that is found and u in the human body. An estimated 1.5 million fractures occur each year in the United States due to osteoporosis. The aim of this study is to evaluate the effectiveness of a calcium nutrition intervention for middle school students in Las Vegas, Nevada. The overarching research question is whether the intervention was successful in improving the calcium nutrition knowledge of the students. Data have been collected from pretests and posttests completed by the students. To determine whether each student benefited from the intervention, the percentage improvement from pretest to the posttest was calculated. Paired t-tests (PROC TTEST), mixed linear models (PROC MIXED), and frequency distributions in SAS ® 9.2 were used. The SAS code can be seen in the Appendix section at the end of the paper
