Seasonal variation in cardiovascular disease risk factors in a subarctic population: the Tromso Study 1979-2008
Background Seasonal changes in cardiovascular disease (CVD) risk factors may be due to exposure to seasonal environmental variables like temperature and acute infections or seasonal behavioural patterns in physical activity and diet. Investigating the seasonal pattern of risk factors should help det...
