  1. Dietary vitamin C and bêta-carotene and risk of death in middle-aged men : the Western Electric Study.

    Article - En anglais

    In the Western Electric Company Study, carried out in Chicago, Illinois, data on diet and other factors were obtained in 1958 and 1959 for a cohort of 1,556 employed, middle-aged men.

    Nutrients included vitamin C and bêta-carotene.

    An index that summarized combined intake of both nutrients was constructed.

    Mean intakes of vitamin C in the lowest and highest tertiles of the index were 66 and 138 mg/day ; corresponding values for bêta-carotene were 2.3 and 5.3 mg/day.

    A total of 522 of 1,556 men died during 32,935 person-years of follow-up, 231 from coronary heart disease and 155 from cancer.

    After adjustment for potentially confounding factors, relative risks (95% confidence intervals) associated with an increment of 19 points in the index (difference between means of the lowest and highest tertiles) were 0.60 (0.39-0.93) for cancer mortality, 0.70 (0.49-0.98) for coronary disease mortality, and 0.69 (0.55-0.87) for all-cause mortality.

    These results support the hypothesis that consumption of foods rich in vitamin C and bêta-carotene reduces risk of death in middle-aged men.
