Official title
Reliability of a Food Frequency Questionnaire in the Assessment of Dietary Intake Including FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols) in Different Populations, and Relationship With IBS (Inflammatory Bowel Syndrome) Symptoms and the Degree of Self-assessed Physical Activity
Overview
During an online assessment participants will fill in questionnaires evaluating demographic data, psychological variables, the degree of self-assessed physical activity and symptoms of irritable bowel. Dietary intake will be assessed by a newly developed food frequency questionnaire (FFQ) and a 4 days food diary. In order to validate the FFQ in different populations, participants will be recruited from university students, staff of UZ Brussel and VUB, and from the community by advertisement (including social media). IBS patients will be recruited from the gastro-enterology outpatient clinic.
Interventions
- Other questionnaire
questionnaire will be filled in by all participants
Primary outcome measures
- To validate the newly developed food frequency questionnaire against the standard 4-day food diary across different populations [Time frame: 2 years]
Secondary outcome measures (3)
- Comparison of dietary and FODMAP intake in IBS vs. non-IBS patients in different populations [Time frame: 2 years]
- Comparison of the degree of physical activity in IBS vs. non-IBS patients in different populations [Time frame: 2 years]
- Comparison of the degree of physical activity and IBS symptom severity in different populations [Time frame: 2 years]
