Bowel function in an urban black African population.

G J Oettlé, I Segal

    Diseases of the Colon and Rectum
    |October 1, 1985
    PubMed
    Summary

    Urban Africans have low fiber intake but also low incidence of fiber deficiency diseases. Their bowel habits resemble westernized populations more than rural Africans, challenging typical fiber deficiency disease associations.

    Area of Science:

    • Gastroenterology
    • Nutritional Science
    • Epidemiology

    Background:

    • Dietary fiber intake is crucial for digestive health.
    • Low fiber intake is typically associated with increased risk of colorectal diseases.
    • Previous studies highlight differences in bowel function between populations.

    Purpose of the Study:

    • To investigate the relationship between dietary fiber intake and disease incidence in an urbanized African population.
    • To compare the bowel habits of urbanized Africans with those of westernized whites and rural blacks.

    Main Methods:

    • Observational study comparing dietary habits and disease incidence.
    • Assessment of stool weight, defecation frequency, and colonic transit time.

    Main Results:

    • Urbanized Africans exhibit low daily dietary fiber consumption.
    • This population shows a low incidence of diseases typically linked to fiber deficiency.
    • Stool weight, defecation frequency, and transit times align more closely with westernized white populations than rural blacks.

    Conclusions:

    • The low incidence of fiber deficiency diseases in urban Africans despite low fiber intake warrants further investigation.
    • Bowel habit parameters may be more indicative of disease risk than dietary fiber intake alone in certain populations.
