To investigate whether school-meal observations influenced children’s 24-hour dietary recalls. Over three school years, 555 randomly selected fourth-grade children were interviewed to obtain a 24-hour dietary recall; before being interviewed, 374 children were observed eating two school meals (breakfast, lunch) and 181 children were not observed. Within observation-status groups (observed; unobserved), children were randomized within sex to one of six combinations from two target periods (prior-24-hours; previous-day) crossed with three interview times (morning; afternoon; evening). For each of five variables (interview length, meals/snacks, meal components, items, kilocalories), naïve and adjusted equivalence tests rejected that observation-status groups were different, indicating that school-meal observations did not influence children’s 24-hour dietary recalls. There was a target-period effect on length (P<0.0001) (longer for prior-24-hour recalls), a school year effect on length (P=0.0002) (longer for third year), and a target-period-by-interview-time interaction on items (P=0.0110) and kilocalories (P=0.0047) (both smaller for previous-day recalls in the afternoon than prior-24-hour recalls in the afternoon and previous-day recalls in the evening), indicating that variables were sufficiently sensitive and psychometrically reliable. Conclusions about 24-hour dietary recalls by fourth-grade children observed eating school meals in validation studies are generalizable to 24-hour dietary recalls by comparable but unobserved children in non-validation studies.
