Secondary risk factors that indirectly increase the risk of stroke by increasing the risk of heart disease include: high cholesterol; lack of exercise; and obesity.
Other factors affecting the risk of stroke:
Geographic location. Strokes are more common in the southeastern United States than in other areas. The same situation is in Ukraine.
Season and climate. Stroke deaths occur more often during extremes (hot or cold) of temperature.
Excessive alcohol intake. Excessive drinking (average of greater than one drink per day for women and more than two drinks per day for men) and binge drinking can indirectly lead to a stroke by raising blood pressure, contributing to obesity, and causing heart failure.
