What is the relationship between body mass index and risk of stroke?
Several studies have examined the relationship between body mass index (BMI) and risk of stroke. Studies have found that being overweight or obese is associated with an increased risk of stroke, especially among women. For example, the JPHC study in Japan found that BMI is positively associated with the risk of stroke in both men and women. Additionally, the study by Kurth et al. found that being overweight or obese is associated with an increased risk of stroke in women, but not in men. Finally, the study by Bazzano et al. found that BMI is a significant risk factor for stroke in both Chinese men and women. Overall, these studies suggest that being overweight or obese is associated with an increased risk of stroke, particularly among women.
