Hypothesis
Is the food frequency questionnaire (CFFQ) a valid tool for assessing dietary intake in children and adolescents?
Conclusion
The CFFQ is a useful tool for assessing dietary intake in younger children, but it underestimates intake in adolescents.
Supporting Evidence
- The CFFQ showed a median correlation coefficient of 0.76 with the first FFQ.
- The AFFQ had a lower ability to rank habitual intake compared to the CFFQ.
- The study found that the CFFQ underestimated dietary intake in adolescents.
Takeaway
This study shows that a special questionnaire can help us understand what kids eat, but it doesn't work as well for older kids.
Methodology
The study involved 103 children who completed two food frequency questionnaires and weighed dietary records over a month.
Potential Biases
Selection bias may have occurred as participants were chosen by teachers, potentially leading to a more health-conscious group.
Limitations
The study had a small sample size and was conducted in only one season, which may affect the generalizability of the results.
Participant Demographics
Participants included 50 young children (3-11 years) and 53 adolescents (12-16 years) from schools in Japan.
