1913 men study - a longitudinal study of the development of stroke in a population.

Risk factors for the development of stroke was studied in a prospective long-term investigation of 855 male in a random population sampled of the same age. After 13 years of follow-up 25 participants had suffered from stroke, which gives an incidence of 19/10,000 annually. At the 1963 year investigation several parametras were studied. The stroke-prone person had higher values of systolic and diastolic blood pressure and had a significant greater total heart volume. Blood parametras as the fasting of serum cholesterole, triglyceride and erytrocyte sedimentation rate were significantly elevated in those who developed stroke. They also tended to consume more coffee and showed a higher tobacco consumption. By applying the multiple regression model it was disclosed that the most predective risk-variables were diastolic blood pressure, erytrocyte sedimentation rate and smoking habits.
