    Article - En anglais

    BACKGROUND

    In a population-based case-control study of colon carcinoma and nutrition involving the francophone community in Greater Montreal, a total of 402 cases (200 males and 202 females) and 668 controls (239 males and 429 females) were interviewed.

    METHODS

    Cases from 1989-1993 were identified through the admission offices of 5 major francophone teaching hospitals in Montreal and were ages 35-79 years.

    Controls matched by age, place of residence, and language were selected by a modified random digit dialing method.

    Information on dietary intake was collected with a quantitative food frequency questionnaire.

    RESULTS

    No associations were evident between colon carcinoma and total energy, protein, or carbohydrate consumption, whereas a suggestive inverse association was found with total fat intake, with an odds ratio (OR) of 0.78 (P=0.0637), and with saturated fat intake as well (OR=0.71, P=0.0893).

    A strongly significant inverse association was found with dietary fiber (OR=0.50, P=0.0018).

    The strongest inverse association concerning fiber was found with fiber from vegetable sources (OR=0.57, P=0.0096), and a suggestive (although nonsignificant) inverse association (OR=0.74, P=0.0687) was found with fiber from fruits.

    Calcium was inversely associated with risk (OR=0.69, P=0.0411), as was dietary intake of vitamin A (OR=0.67, P=0.0162), retinol, (OR=0.069, P=0.0409), vitamin E (OR=0.53, P=0.0028), and alphatocopherol (OR=0.63, P=0.0256). (...)
