Eg. Toporoff et al., DO CHILDREN EAT WHAT THEY SAY - VALIDITY OF INTENDED FOOD CHOICES AMONG NATIVE-AMERICAN SCHOOL-CHILDREN, Obesity research, 5(2), 1997, pp. 87-92
Objective, To examine the agreement between school children's intended
food choices and observed food choices. Design. Native American stude
nts in the second through fifth grade completed a questionnaire that a
sked them to select from 10 paired food choices for a given meal or sn
ack. Three weeks later students chose among foods identical to those o
n the questionnaire as part of their usual school lunch or breakfast o
ver three consecutive days; afternoon snacks were also offered. Result
s, Agreement between students' intended food choices and observed food
choices was examined across 10 food pairs. The composite kappa coeffi
cient between intended and observed food choices was 0.09 (95% confide
nce interval 0.06, 0.12), indicating virtually no agreement above that
expected by chance. There were no differences in agreement by sex or
grade. Conclusions, Intended food choices were not significantly assoc
iated with observed food choices. It is unclear whether intended food
choices reflect nutrition knowledge, socially desirable responses, foo
d preferences, or some other dimension of eating behavior. Although re
sponsive to school-based nutrition interventions, the interpretation o
f changes in intended food choices must be clarified in future researc
