Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To validate the newly developed food frequency questionnaire against the standard 4-day food diary across different populations		2 years
Secondary	Comparison of dietary and FODMAP intake in IBS vs. non-IBS patients in different populations	differences in number and type of FODMAP intake between groups	2 years
Secondary	Comparison of the degree of physical activity in IBS vs. non-IBS patients in different populations	differences and correlation of IPAQ (International Physical Activity Questionnaire) scores between groups, IPAQ evaluates the level of physical activity. Scoring a HIGH level of physical activity on the IPAQ means your physical activity levels equate to approximately one hour of activity per day or more	2 years
Secondary	Comparison of the degree of physical activity and IBS symptom severity in different populations	differences and correlation of IPAQ scores between groups; IPAQ evaluates the level of physical activity. Scoring a HIGH level of physical activity on the IPAQ means your physical activity levels equate to approximately one hour of activity per day or more	2 years
