  1. Fulltext. Nutrient intake in relation to bladder cancer among middle-aged men and women.

    Article - En anglais

    Fulltext.

    This population-based case-control study examined the association between selected nutrients, foods, and diet behaviors and bladder cancer.

    Bladder cancer cases (n=262) were identified from the Surveillance, Epidemiology, and End Results Program cancer registry for western Washington, and controls (n=405) were identified through random digit dialing.

    Cases were diagnosed between January 1987 and June 1990, and eligible subjects were Caucasian, aged 45-65 years, and residents of King, Pierce, or Snohomish counties.

    Subjects completed a self-administered, 71-item food frequency questionnaire and a structured telephone interview.

    Analyses were conducted by logistic regression analysis and included adjustment for age, sex, smoking (current, former, never), and county.

    Odds ratios and their 95% confidence intervals for highest versus lowest level of intake were examined.

    An inverse association was found between the risk of bladder cancer and dietary retinol (odds ratio (OR) across quartiles : 1.00,1.09,0.97, and 0.52 ; 95% CI 0.29-0.97 ; trend p value=0.03) and dietary vitamin C (OR across quartiles : 1.00,0.96,0.67, and 0.50 ; 95% CI 0.28-0.88 ; trend p value=0.009), adjusted for calories.

    The use of multivitamin supplements daily over the 10-year period ending 2 years before diagnosis versus no use was associated with a decreased risk of bladder cancer (OR=0.39 ; 95% Cl 0.24-0.63) as was use of supplemental vitamin C (OR for>502 mg/day over the 10 years vs. none=0. (...)
