| Research Abstract |
To investigate correlation between cancer and dietary hadits of the patients, 30- 69 year-age classes of members of the National Health Insureance System from the general populations in 20 cities, towns and villages of Japanese rural areas were asked on the present status of 60 kinds of foods, beverages and tobacco which have been reported to have any relationship with cancer incidences through life stage. The survey was made about every decades from past and present. More than 50,000 persons were surveyed. However, 31,505 persons were judged as effective as the cohort.
Among 60 kinds of foods, 10 aqnd 7 were classified as the mutagen-positive and the mutagen-negative food groups and were given the positive and the negative scores, respectively.
The evaluation of the food habit was made by follow-up the intake pattern of the mutagen-positive and the -negative food scores by age-group.
On the other hand, the cancer patients were listed from the deaths certificates and the National Health Insurance medical records, and the correlations between the dietary patterns and the cancer sites were observed among 265 patients so far collected.
These preliminary results showed that in the gastic cancer patients, they take more often rice bowls and alcoholic beverages, the patients of colon and recttum cancer take more wild plants such as brakens and fungus, the lung cancer patients took more meats and fishes, also they took more tobaccos than other cancer patients or than controls. Breast cancer patients also took more meats and fishes and also tobaccos. Our cohorts showed to be very useful to follow the relationship between cancer mortality or incidence and dietary patterns of various cancers as cohort study.
