Abstract
The incidence of tussive and phlegmatic symptoms has increased among older persons, even those living in rural areas, in Japan. Since 1959 a comprehensive health care program has been available for all inhabitants in the rural village of Yachiho in Nagano Prefecture. A comparative study of mortality data was performed for this population taking the years 1960 to 1967 and comparing that data with data collected for the years 1968 to 1975. A 25 percent drop in cerebrovascular attack and a 4 percent drop in cancer were noted in the later time period. Heart disease increased by 14 percent. The incidence of respiratory cancer increased 22 percent, primarily among older individuals. Deaths due to pneumonia and bronchitis decreased by half. A check was made of the ratio of appearance or worsening of tussis and sputum in regard to 459 individuals who were engaged in farm work. The ratio was low in rice transplanting work and in rice reaping; but it was high in rice threshing. In a study of the dust discharged during rice threshing at least 10 to 15 milligrams of dust was inhaled per 10 acres threshed. Some of the particles exceeded 100 micrometers and had a granular form. The repeated occurrence of thresher's bronchitis yearly over many years gives rise to chronic bronchitis and increases the incidence of pneumoconiosis. The author indicates the importance of using personal protective equipment for individuals engaged in rice threshing.
