NOTES: NSLP = National School Lunch Program; SBP = School Breakfast Program; SNDA-III = third School Nutrition Dietary Assessment study; y = years. The bold font in the columns for the NSLP participants show the range for the percentage of the day’s calories consumed at lunch, and the bold font in the columns for the SBP participants show the range for the percentage of the day’s calories consumed at breakfast. aThe percentages that are based on recall data represent the percentages of calories from eating occasions that occurred during specified time periods, following rules developed for the School Nutrition Dietary Assessment study (USDA/FNS, 2007a). bThe percentages of student-defined values represent the percentages of calories from eating occasions that the students defined as breakfast, lunch, dinner, and snacks.

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. |

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. |
