Conclusions of the research in the Seven Countries
With hundreds of peer-reviewed publications, the Seven Countries Study generated an incredible amount of information. We’ve selected 82 main results and summarized them for you in our articles.
Diet, risk factors and coronary heart disease rates in the 16 cohorts of the Seven Countries Study
Early on in the study Ancel Keys and colleagues noticed interesting associations across cultures in the Seven Countries Study; cultures differed in their diets and corresponding differences were seen in saturated fat, serum cholesterol, and coronary heart disease (CHD) incidence after 5 and 10 years of follow-up.
Follow-up after 25 and 50 years
These associations were repeated using 25-year and 50-year CHD mortality data and extended with associations on flavonoids and dietary patterns.

Since the first measurements in 1958, the Seven Countries Study focused on predictors of cardiovascular disease (CVD) outcomes.
Risk factors like serum cholesterol and blood pressure level were related to CHD and blood pressure was also associated with stroke.
Diet, including nutrients, foods and dietary patterns varied widely among countries. The different aspects of diet and CVD were studied in cohorts and individuals.
Lifestyle may be the most personal category and habits like smoking or alcohol were investigated in relation to CVD.
From 1984 onwards, additional studies started to examine indicators of healthy aging in the elderly populations of in the SCS and related studies.
All-cause mortality is proxy variable for life expectancy. Here we examine cardiovascular predictors in relation to all-cause mortality.
Mental health is a major contributor to quality of life. We investigate predictors of cognitive decline, depression and optimism.
Physical health is a key element of healthy ageing. Physical activity and other lifestyle choices may impact the physical functioning of the body.
