Mortality data were obtained from the registration records of the population of 148,928 during 1983 to 1988, which provided 744,640 person-years of observation.
The data regarding average consumption of each kind of grain, potatoes and sweet potatoes were from food allocation records.
The data regarding consumption of meat, eggs, fruit, vegetables and the data regarding alcohol drinking were from interviews.
The concentrations of nitrite and of nitrate in pickled vegetables and in drinking water were measured.
