Summary
A new internet-based diet questionnaire for Chinese (IDQC) was developed and validated for assessing dietary intake in Northern China. The IDQC demonstrated satisfactory consistency with diet diaries for food groups and nutrients.
Area of Science:
- Nutritional epidemiology
- Dietary assessment methodology
Background:
- National dietary surveys are crucial but challenging to implement in China.
- Accurate dietary assessment tools are needed for public health and clinical nutrition research.
Purpose of the Study:
- To develop and validate an internet-based diet questionnaire for Chinese (IDQC).
- To assess dietary intake in the Northern China population.
Main Methods:
- Recruited 292 city residents in Harbin.
- Validated the IDQC against 3-day diet diaries using paired t-tests and Pearson's correlations.
- Assessed agreement using cross-classification in quartiles.
Main Results:
- Positive correlations observed between IDQC and diet diaries for all food groups (0.28-0.63) and nutrients (0.37-0.98).
- Overall agreement for food groups and nutrients exceeded 69.2%, indicating good consistency.
- High correlation (0.98) found for iodine intake.
Conclusions:
- The IDQC is a reliable tool for estimating food and nutrient intake in Northern China.
- The IDQC is suitable for clinical nutrition epidemiology and public health nutrition.
- The IDQC system (v1.0) is publicly available online.
