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

Assessment of the Gastrointestinal System II: Health Perception Pattern

162
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
  • Public Health Nutrition
  • Dietary Assessment Methods

Background:

  • Developing region-specific dietary assessment tools is crucial for accurate nutritional epidemiology.
  • Existing food frequency questionnaires (FFQs) may require adaptation for diverse populations.
  • Xi'an City, Shaanxi Province, presents a unique dietary landscape for study.

Purpose of the Study:

  • To establish an efficient and region-specific semi-quantitative food frequency questionnaire (SQFFQ).
  • To create a simple, effective, and widely applicable dietary measurement tool.
  • To validate the developed SQFFQ for use in Xi'an, Shaanxi.

Main Methods:

  • Development of an initial FFQ and 24-hour dietary recall survey (24hDR) for 129 common food items.
  • Combined methods to enhance questionnaire convenience and credibility.
  • Reliability and validity testing of the developed SQFFQ.

Main Results:

  • A 104-item SQFFQ was finalized after collecting 367 questionnaires (FFQ and 24hDR).
  • High correlation coefficients (Pearson 0.60-0.75, Spearman/Kendall 0.50-0.89, CCC 0.5-0.95) were observed between repeated SQFFQ administrations.
  • Strong agreement (75-80% in identical or adjacent tertiles) was found between the SQFFQ and 24hDR for energy and nutrient intake.

Conclusions:

  • The developed SQFFQ is a reliable and valid tool for assessing nutrient intake in Xi'an, Shaanxi.
  • This SQFFQ can be effectively utilized in dietary pattern surveys and nutritional correlation studies.
  • The method provides a model for developing region-specific dietary assessment tools.
