NOTES:

*Estimates may not be reliable due to inadequate cell size or a large coefficient of variation. Standard error not displayed when percentage is less than 3 or greater than 97. Sample excludes students with unreliable height or weight data. kcal = calories; N = sample size; SE = standard error.

SOURCE: Third School Nutrition Dietary Assessment study (SNDA-III) (USDA/FNS, 2007a), 24-hour dietary recalls, school year 2004–2005. Weighted tabulations based on first and second 24-hour recalls prepared by Mathematica Policy Research, Inc. Usual intake distributions were determined for each subgroup using the PC version of the Software for Intake Distribution Estimation (PC-SIDE) (ISU, 1997). Sample includes all students, including those who did not consume a lunch.
