Assessment of the Gastrointestinal System II: Health Perception Pattern01:29

Assessment of the Gastrointestinal System II: Health Perception Pattern

152
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Area of Science:

  • Nutritional Epidemiology
  • Digital Health Technologies
  • Dietary Assessment

Background:

  • Epidemiological research increasingly utilizes digital data collection methods.
  • Traditional dietary assessment tools face challenges in scalability and ease of use.
  • Development of user-friendly, digital tools is crucial for advancing nutritional epidemiology.

Purpose of the Study:

  • To evaluate the validity and reproducibility of a novel computerized Food Frequency Questionnaire (FFQ).
  • To assess the usability and digital capabilities of the developed FFQ for large-scale research.

Main Methods:

  • Dietary intake assessed via 24-hour Dietary Recalls (DRs) and the new FFQ (133 items).
  • FFQ features include visualized portion sizes, food group categorization, and processing levels.
  • Reproducibility tested with two FFQ submissions; validity compared FFQ to three 24-h DRs for nutrient intake.

Main Results:

  • FFQ showed moderate to high reproducibility for nutrient and food group intake (ICC 0.53-0.83).
  • Spearman's correlation indicated moderate to strong agreement for specific food items (p < 0.05).
  • FFQ generally overestimated nutrient intake compared to DRs, indicating acceptable validity.

Conclusions:

  • The developed digital FFQ exhibits moderate to high reproducibility and acceptable validity.
  • Its user-friendly interface and digital format support large-scale, multilingual nutritional research.
  • The tool is adjustable and easy to use, enhancing dietary data collection efficiency.
