title: The diffusion of cardiovascular disease in the Norwegian farming community: a combination of morbidity and mortality data.
abstract: This article analyses an observed increase in cardiovascular morbidity among male farmers in Norway during the last decade in the light of the traditionally low mortality in farmers. Three hypotheses to explain the increases in CVD morbidity are tested, of which one, stating that there is a time lag in the spread of risk factors, proves to be most fruitful. Mortality data for agricultural communities show no increase in overall CVD rates, but when age-specific rates are analysed, an increase in the younger age groups emerges, especially for ischaemic heart disease. If this process continues, farmers and farming areas may change from low to high mortality, relatively speaking. It is argued that this change is due to a time lag in two waves, first an increase in risk factors such as smoking, more fatty diets and less physically demanding work, then improved lifestyles due to a better perception of risk factors. Both waves may be affecting rural areas later than the urban centres. Knowledge of such geographical and socio-economic diffusion processes is important in the planning and implementation of prevention programmes.
