| Summary |
In a cohort study, which is a method of conducting epidemiological research, people with and without a certain factor (e.g., smokers and non-smokers) are observed for a number of years and the incidence of disease (or death) is examined. The researcher then estimates the number of times a certain factor increased susceptibility to the disease, compared to the probability of the same outcome in the absence of that factor. One of the major findings of such research so far is that cigarette smokers are more likely to develop lung cancer than non-smokers. In Japan, a large cohort study called the “Six Prefectures Cohort” was initiated in the late 1960s by the late Dr. Yu Hirayama. This study revealed that women who do not smoke are more likely to develop lung cancer if their husbands smoke, compared to women whose husbands do not smoke, and that cigarette smoking is not only associated with the development of lung cancer but also cancers in many other parts of the body. The lifestyle habits of Japanese people (e.g., smoking habits, eating habits, exercise habits, etc.) are said to have changed significantly in recent years. Coincident with these changes, both the number and rate of cancer deaths are increasing year by year, necessitating not only the study of effective treatment methods but also the implementation of appropriate cancer prevention measures in Japan. The JACC study was initiated in 1988 by Professor Kunio Aoki of Nagoya University, with the cooperation of several institutions, and funded by the Ministry of Education, Culture, Sports, Science and Technology (then the Ministry of Education, Culture, Sports, Science and Technology). The purpose of this cohort study was to clarify the relationship between Japanese people’s recent lifestyle and cancer. The study involved about 120,000 members of the general public. The data provided are baseline information and follow-up results (deaths/transfers and follow-up period) for a portion of the JACC study follow-up subjects (80,365 subjects). The number of subjects was limited because the survey items corresponding to the baseline information excluded special districts. In 31 of the surveyed districts (about 50,000 people), an interim survey was conducted about five years after the baseline survey, but the results are not included among the data provided. |
