Hypothesis
The study aims to determine the reliability and relative validity of a child nutrition questionnaire assessing dietary patterns and food behaviours in children.
Conclusion
The child nutrition questionnaire is a valid and reliable tool for assessing dietary patterns and food behaviours in Australian school children aged 10–12 years.
Supporting Evidence
- The questionnaire was developed to measure dietary patterns and food behaviours relevant to childhood obesity prevention.
- Test-retest reliability showed ICCs ranging from 0.47 to 0.66 for most scores.
- Spearman correlations for validity ranged from 0.34 to 0.48.
Takeaway
Researchers created a questionnaire to help understand what kids eat and how they feel about food, and found it works well.
Methodology
A 14-item questionnaire was administered to children aged 10-12 years, with test-retest reliability assessed using ICC and validity assessed with Spearman correlations.
Potential Biases
Potential overestimation of fruit and vegetable intake due to children's difficulty in estimating portion sizes.
Limitations
The questionnaire's complexity may have affected the accuracy of responses, and the food diary used for validation was not a validated tool itself.
Participant Demographics
62% female, approximately one-third from each grade (36% grade five, 33% grade six, 31% grade seven), 66% from metropolitan schools, 61% from public schools.
