To examine the associations between dietary fat intake and ischemic stroke among postmenopausal women.We conducted a prospective cohort study of 87,025 generally healthy postmenopausal women (age, 50-79 years) enrolled in the Women's Health Initiative Observational Study. Repeated and validated dietary assessments were done using a self-administered food frequency questionnaire. We used Cox proportional hazards models to estimate hazard ratios (HRs) of ischemic stroke based on quintiles of the c...
