An epidemiological study on adult diseases among Japanese rural inhabitants - Mortality of inhabitants after mass health screening / 日本農村医学会雑誌

ABSTRACT

A follow-up study was conducted until the end of 1980 on 28, 643 rural inhabitants who had undergone mass health screening between 1971 and 1978. For those who died, the causes of death were confirmed by death certificates.<BR>The results obtained were as follows<BR>1) During the observation period, there were 876 death (about 3% of participants). The mortality was three times greater for males than for females and increased with age. These differences between sexes were statistically significant except the group of 29years old or under.<BR>2) Forty-two percent of the total deaths were for cerebro-cardiovascular diseases, 32% for malignant neoplasms and 26% for others. For males, the mortality of cerebro-cardiovascular diseases was greater than those of other causes of death. On the other hand, the mortality of malignant neoplasms was higher among females.<BR>3) The mortality rate per 1, 000 person-years of observation was 5.2 (11.8 for males and 3.2 for females). Cause- specific mortality rates were 1.7 per 1, 000 person-years for malignant neoplasms (3.1 for males and 1.2 for females); 1.2 for cerebrovascular diseases (2.8 for males and 0.7 for females), 0.9 for cardiovascular diseases (2.3 for males and 0.5 for females), 0.3 for accidents and 0.2 for pneumonia. The mortality rates of each aged-group according major causes of death were higher among males than among females except two groups of 29 years old or under and 70 years old or over of cerebral bleeding.
