Abstract
Objective: To evaluate a web-based nutritional knowledge questionnaire for primary-school children. Design: Children's nutritional knowledge was assessed in five domains: healthy choices (twenty-seven items), estimated recommended portions/servings (eight items), nutrient content (five items), main food function (five items) and categorization of food items (eight items). Setting: The questionnaires were completed in school. Subjects: A convenience sample of 576 Belgian children (aged 7-12 years) from fourteen primary schools completed the questionnaire once, 386 completed the questionnaire twice. Results: Healthy choices could be answered correctly by 73% of the children, nutrients by 59 %, food categorization by 49 %, main function by 38% and portion estimation by 36 %. Children's test-retest intra-class correlations were 0.75 for healthy choices, 0.33 for nutrients, 0.61 for food categorization, 0.44 for main function, 0.47 for portion estimation and 0.76 for the total scale. The intra-class correlation was lower in the youngest age group (grade 2: 0.51, grade 4: 0.65, grade 6: 0.66). The total score was significantly lower in the retest. The instrument was in general positively evaluated by the children. Conclusions: The instrument is a promising, practical, inexpensive tool with acceptable test-retest reliability in fourth and sixth graders.
