Abstract
We studied as to whether the incidence of heart diseases in farm areas and in non-farm. areas is different or not. The areas, where the percentage of farm households exceeds 80 per cent of all the households in the areas, were defined by us as the farm areas, and the areas, where the percentage of non-farm households exceeds 80 per cent of all the households in the areas, were defined as the non-farm areas. As heart diseases were the following diseases defined: arteriosclerotic and degenerative heart disease, other heart disease, cardiac arrythmia, arterial disease, venous disease and disease of lymphatic vessel and lymphatic gland. We examined the consultation rates of heart diseases during about two years among all those who carried the National Health Insurance in Toyama Prefecture, comparing farm areas with non-farm areas. When the following two conditions were taken in consideration, such as the difference of the consultation rates of all the diseasesa nd the difference of the incidence of new diseases from those, who consulted doctors, in these two areas, the consultation rates of heart diseases in farm. areas were significantly higher than those in non-farm areas, as well as the consultation rates of hypertension and cerebrovascular disturbances Moreover, we divided all the diseases in 33 categories and studied the differences of the consultation rates of these diseases in farm areas and in non-farm areas, which were also reported.
