Abstract

Background There is a paucity of accurate data regarding any association in the general population between defecation and lifestyle factors such as diet, exercise, physique, and childbirth.Aims of the study To evaluate the effects of such lifestyle factors on defecation among regional residents of Japan.Methods Residents (n = 1,699) of northern Japan, aged over 40 years, were surveyed in 1995 using a questionnaire to assess their lifestyle factors (diet, beverage consumption, exercise, physique, and childbirth), and examining their defecation status. We evaluated the relationship between these lifestyle factors and defecation using logistic regression analysis. The authors used four measures (defecation frequency, subjective defecation state, subjective fecal properties, and fecal consistency) and assigned the subjects to a group defined by their defecatory status: constipation, diarrhea, or normal, depending on the responses of the subjects to all four criteria.Results The tendency for constipation correlated positively with age in males ( p = 0.130), although this trend was not observed in females ( p = 0.641). Of the dietary factors examined, only rice, which accounts for the largest proportion of daily dietary fiber intake in Japan, demonstrated a preventive effect on constipation in both sexes ( p = 0.050 in males and 0.003 in females). Walking was a preventive factor for constipation among males ( p = 0.049), and alcohol also inhibited constipation among males ( p = 0.007).Conclusions These results suggest that exercise, such as walking, and a high intake of dietary fiber, such as rice, were useful in the maintenance of defecation.

  • The decreased abundance of Prevotella in functional constipation is consistent with the observation that functional constipation patients usually have a low-fiber diet.

    “Therefore, the decreased abundance of Prevotella in FC is consistent with the observation that FC patients usually have a low-fiber diet [ 30 , 31 ].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
