Bowel habit in a Yoruba rural community: preliminary report

The bowel habit of a rural population 80 kilometres outside Ibadan was examined. Based on the pattern of the diet there, 91% of the apparently healthy subjects have daily bowel actions, 60% have two or more motions a day and the stool was soft in 51% of them. There was no alteration in the frequency and consistency of the stool with advancing age. The range of bowel actions was two to three soft motions per day. Recognizable dietary factors producing this pattern include not only the bulky carbohydrate diet but also the vegetables, pepper, fruits and traditional as well as proprietary laxative products commonly taken by these subjects. The implication of the bowel habit on the prevalence of certain gastrointestinal disease on the basis of Burkitt's hypothesis was examined. Measurements of food transit time and stool weights will form the basis of subsequent studies.
