Deaths from heart disease as analyzed according to occupation

"In order to analyze the deaths from heart disease associated with various occupations, we examined [1985 vital statistics for Japan] and calculated the risk ratio as well as the attributable risk percent (ARP), for deaths from all forms of heart disease, from ischemic heart disease, [and] from heart failure. The risk ratio for all forms of heart disease was highest in Group E (agricultural, forestry and fisheries workers) and Group F (mining workers) in most age groups. The second highest ratio was seen in Group J (service workers), especially those in their 30s and over. The ratio was also higher in Group D (sales workers) in their 50s and over."
