At school breakfast, this child was observed eating vanilla milk and cheese toast; for school breakfast, this child reported eating vanilla milk, syrup, and French toast. At school lunch, this child was observed eating hot dog, vanilla milk, and brownie; for school lunch, this child reported eating hamburger, vanilla milk, and brownie.
Every food item that was observed, reported, or both observed and reported is listed.
From the Nutrition Data System for Research database (NDS-R, version 4.03, Nutrition Coordinating Center, University of Minnesota, Minneapolis, MN, 2000), product information, or recipes obtained from the school district’s nutrition program.
All energy values are products of serving amounts and energy per serving. Reference energy is either corresponding or unreported; thus, in each row, corresponding energy from matches + unreported energy from matches + unreported energy from omissions = reference energy. Reported energy is either corresponding or overreported; thus, in each row, overreported energy from intrusions + overreported energy from matches + corresponding energy from matches = reported energy.
M = match; O = omission; I = intrusion. (See Table 1 for definitions.)
Overreported energy from intrusions = energy from intrusions.
Overreported energy from matches = the part of reported energy from matches that exceeded reference energy.
Corresponding energy from matches = the part of reported energy from matches that was less than or equal to reference energy.
Unreported energy from matches = the part of energy from matches for which reference energy exceeded reported energy.
Unreported energy from omissions = energy from omissions.
Applesauce was observed on this child’s tray, but none was eaten; this child mentioned applesauce during the interview but reported that none was eaten. Pineapple was observed on this child’s tray but none was eaten and pineapple was not reported by this child during the interview. Neither applesauce nor pineapple was included when calculating reporting accuracy for this child.
