  1. Physical activity, water intake and risk of colorectal cancer in Taiwan : A hospital-based case-control study.

    Article - En anglais

    The age-adjusted mortality rates of colorectal cancer have been rising in Taiwan over the past 2 decades, and colorectal cancer is now the third leading cause of cancer mortality in the country.

    We conducted a hospital-based case-control study to clarify the nature of the association between physical activity, water intake and colorectal-cancer risk in Taiwan.

    A total of 163 subjects (aged 33-80 years) with histologically confirmed primary colorectal cancer and 163 hospital controls were enrolled during 1992.

    Dietary intake, physical activity and other lifestyle activities were assessed using a comprehensive food-frequency and lifestyle-activity questionnaire.

    Adjusted odds ratios (OR) and 95% confidence intervals (Cl) were estimated using conditional logistic-regression analysis.

    A strong inverse dose-response relation between increased water intake and rectal cancer was found among men after adjustment for other risk factors (p for trend=0.0005).

    The OR for rectal cancer among men in the highest tertile of water intake was 0.08 (95% Cl, 0.02-0.35) compared with that among men in the lowest tertile (OR=I).

    Similar but not significant trends were seen among women (p=0.29).

    The OR for colon cancer among men with active leisure-time physical activity was 0.19 (95% Cl, 0.05-0.77) times that among sedentary men (p for trend=0.03).

    However, physical activity was not associated with colon-cancer risk among women (p=0.48). (...)
