Objective:
Evidence regarding the association between exercise habits and irritable bowel syndrome (IBS) remains scarce in a young population. It is also unknown whether the existence of an exercise partner affects this issue. The purpose of this study was to explore the association between exercise habits that include an exercise partner and IBS in a young Japanese population.
Methods:
This study enrolled 8923 Japanese university students and examined exercise frequency and intensity, and exercise partners using self-administered questionnaires. IBS and functional dyspepsia were defined according to the Rome III criteria.
Results:
The prevalence of IBS in this survey was 6.5%. Moderate frequency exercise was inversely related with IBS [adjusted odds ratio (aOR): 0.65 (95% confidence interval, CI: 0.51-0.83), P for trend = 0.005]. Moderate and high exercise intensities were independently and inversely related with IBS, respectively [aORs were moderate: 0.76 (95% CI: 0.61-0.95) and high: 0.62 (95% CI: 0.48-0.78), P for trend = 0.001]. Exercising with a group or with friends instead of alone was independently inversely related with IBS [aOR with groups: 0.53 (95% CI: 0.40-0.70) and with friends: aOR 0.71 (95% CI: 0.54-0.93)]. After excluding subjects with overlapping IBS and functional dyspepsia, an inverse association between high intensity of exercise or exercise in a group and IBS remained significant.
Conclusion:
The frequency and intensity of exercise may be independently inversely related with IBS in a young Japanese population. Also, exercise with others may be important for preventing IBS.
