Outcome measures
Primary outcome
- Disease characteristics; date of first complaints and diagnosis, date of last
complaints due to IBD and/or IBS and type of complaints, frequency of
complaints, and occurrence of extra-intestinal manifestations.
- Lifestyle characteristics; dietary intake, smoking behaviour, alcohol use,
stress, depression, anxiety, physical and sexual abuse.
Secondary outcome
- Clinical characteristics; measles vaccination or (perinatal) infection,
gastroenteritis, appendectomy, cholestectomy, hysterectomy, use of antibiotics,
and use of oral contraceptive and hormone replacement therapy (for women only),
family members with UC, CD, or IBS.
- Treatment characteristics; number of hospitalizations due to IBD or IBS,
number and kind of operations due to IBD, medication use including analgesic,
and Prednisone and Prednisolon.
Background summary
Ulcerative colitis (UC) and Crohn*s disease (CD), both inflammatory bowel
diseases (IBD), and irritable bowel syndrome (IBS) are common diagnoses in
gastroenterology. Several factors may influence the development or course of
IBD and IBS: lifestyle factors, like smoking, dietary intake including
probiotic use, and psychosocial factors including stress, but also clinical
factors like infection and vaccination, appendectomy, and use of oral
contraceptives, analgesics, and antibiotics. Genetic factors might also
influence the development and course of IBD and IBS. Unfortunately, causal
relationships are hard to establish and a lot of controversies exist about
underlying mechanisms. Our study is unique because it describes clinical
factors as well as lifestyle factors, resulting in a broad overview of
suggested factors for the development and course of IBD and IBS. Since IBD and
IBS are studied simultaneously and with the same methods, comparisons can be
made between the IBD and IBS population.
Study objective
At first, to describe the UC, CD, and IBS outpatient population in the
Netherlands. Secondly to gain insight into disease and treatment
characteristics, as well as lifestyle and clinical factors identified as
potential risk factors of a UC, CD, and IBS outpatient population in the
Netherlands. Thirdly, to search for associations between disease and treatment
characteristics and (changes in) lifestyle and clinical factors. Finally, to
assess the feasibility of a prospective cohort study with IBD and IBS
outpatients.
Study design
Mono-centre cross-sectional study.
Study burden and risks
Participating in the IDeaL study means filling in a questionnaire about disease
and treatment characteristics as well as lifestyle and clinical factors, and
personal information. This will take approximately 30 minutes. There are no
risks for the participants of this study.
