The focus of the Seven Countries Study was on population differences in risk factors, CHD risk and rates, first among cohorts and then within. The long-term follow-up provided information on trends in risk factors and CHD mortality among and within countries.
Trends on risk factors and CHD mortality
Here you can find a visual representation of the trends for serum cholesterol levels, blood pressure, BMI, smoking and diabetes during 25-years of follow-up and for CHD mortality during 40 years of follow-up. It should be noted that these trends are in surviving cohorts and do not accurately represent time trends in the population of these areas.
