Epidemiologic studies of coronary heart disease and stroke in Japanese men living in Japan, Hawaii and California: mortality.
Stroke, coronary heart disease (CHD) and total mortality are evaluated from death certificates in enumerated cohorts of 45-64-year old Japanese men in Hiroshima and Nagasaki (1965-1970), in Homolulu (1966-1970), and in the San Francisco area (1968-1972). Total mortality is highest in Japan with no consistent differences between Japanese Americans in Homolulu and San Francisco. Age-specific CHD death rates are markedly lower in all three Japanese groups than in American whites. The CHD rates are consistently and significantly lower in Japan that in American Japanese. Stroke death rates for American Japanese men appear equivalent to figures for US white men of the same age, but are significantly lower than in the Japan cohort for the 60-64-year-old group. The number of stroke deaths below that age are too few as yet for analysis. Validation of mortality ascertainment and of the accuracy of death certification has been carried out in Japan and in Hawaii. The international differences in mortaltiy do not appear to be due to certification or other methodologic artifact.
