The Relationship between the Severity of Constipation and Exercise Status in the Japanese Population according to Questionnaire Survey

Abstract

Objective. The Japanese guideline for the treatment of chronic constipation recommends that nonpharmacological treatment be applied. However, only a small proportion of patients with constipation seek medical care, and even when they do visit a hospital for constipation in Japan, most are only prescribed medication. This is because the effectiveness of exercise therapy for constipation is still unclear. The purpose of this study was to evaluate the prevalence of constipation in Japanese subjects and the relationship between constipation and exercise. Methods. We conducted a questionnaire survey over a period of four months to determine the prevalence of chronic constipation in nonexercise and exercise groups, as well as the effectiveness of exercise on chronic constipation. Subjective constipation was defined by the constipation scoring system. Multiple regression analysis was performed on risk factors for high constipation scoring system scores, and factors related to constipation symptoms were extracted. Result. We analysed responses regarding 556 participants ranging in mean age 35.6 ± 17.2 years. The constipation scoring system score was significantly higher in the nonexercise group than in the exercise group. Independent predictors for the constipation scoring system score were sex, implementation of exercise, and presence of disease under treatment. Conclusion. The result showed that independent predictors for the constipation scoring system score were sex, implementation of exercise, and presence of disease under treatment. Thus, the present study demonstrated that exercise affects constipation symptom.
