Summary

Constipation is a symptom based disorder with a prevalence of 15% in the adult population and its management remains challenging. Although not life threatening, constipation is associated with impaired quality of life, increased healthcare costs and excess work absenteeism. Constipation represents a heterogeneous disorder with a multifactorial pathogenesis. Several risk factors have been suggested to lead to the condition and are divided in 3 main categories: a) physiological, b) environmental and c) demographic. To date, there is lack of large epidemiological studies on proposed aetiological factors of constipation, especially studies assessing all proposed risk factors of constipation together. The overall aim of this study is to investigate the multidimensional (physiological, environmental and demographic) predictors of constipation with the use of a multivariate analysis statistical model. This is a large single centre case control study comparing constipated adults with healthy individuals matched for age, gender and ethnicity. The duration of the study is 2 weeks in total and includes a screening visit, a 2 week run-in period and a baseline visit at the end of the run-in period. Transit time between constipated and healthy individuals is assessed at baseline visit. Differences in gastrointestinal symptoms, dietary intake as well as differences in stool output (e.g. stool frequency and consistency) between constipated and healthy individuals are assessed over the baseline period (the week before the baseline visit). Differences in female sex hormone levels as well as stool markers and markers of fermentation (e.g. fecal water, stool pH, short chain fatty acids) between constipated and healthy individuals are assessed at baseline visit. Furthermore, differences in environmental measures (physical activity, anxiety, smoking) and differences in demographic measures (age, gender, body mass index) between patients suffering from constipation and healthy individuals are also assessed at baseline visit.
