  1. Relation of consumption of Vitamin E, Vitamin C, and carotenoids to risk for stroke among men in the United States.

    Article - En anglais


    Antioxidants increase the resistance of low-density lipoprotein to oxidation and may thereby reduce risk for atherosclerosis.


    To determine whether intake of vitamin E, vitamin C, or carotenoids predict risk for total or ischemic stroke.


    Prospective observational study.


    The Health Professionals Follow-up Study.


    43 738 men 40 to 75 years of age who did not have cardiovascular disease or diabetes.


    Repeated and validated dietary assessments were done by using a self-administered 131-item food-frequency questionnaire, which included questions on dose and duration of vitamin supplement use.

    The follow-up period was 8 years.


    A total of 328 strokes occurred : 210 ischemic, 70 hemorrhagic, and 48 unclassified.

    After adjustment for age, smoking, hypertension, hypercholesterolemia, body mass index, physical activity, parental history of myocardial infarction, alcohol consumption, and total energy intake, the relative risk for ischemic stroke in the top quintile of vitamin E intake (median, 411 lU/d) compared with the bottom quintile (5.4 lU/d) was 1.18 (95% Cl, 0.77 to 1.82).

    The relative risk for ischemic stroke in the top quintile of vitamin C intake (1167 mg/d) compared with the bottom quintile (95 mg/d) was 1.03 (Cl, 0.66 to 1.59).

    Results for total stroke were similar

    Associations of vitamin intake with hemorrhagic stroke were also nonsignificant, but the Cls were wide. (...)
