R. M. Worth: Article Analysis

In the study posted in the American Journal of Epidemiology, by R. M. Worth, who is affiliated with the University of Hawaii School of Public Health, Biomedical Sciences Building, 1960 East-West Road, Honolulu, Hawaii 96822; H. Kato who is affiliated with the Atomic Bomb Casualty Commission and Japanese National Institute of Health, Hiroshima and Nagasaki, Japan; G. G. Rhoads and A. Kagan, who is affiliated with the Honolulu Heart Study, National Heart and Lung Institute, and National Institutes of Health; and S. L. Syme, who is affiliated with the Department of Epidemiology, University of California School of Public Health, Berkeley, observes the epidemiologic studies of stroke and coronary heart disease of Japanese men currently residing
in the country and states: Japan, Hawaii and California. The study is funded and supported by the Epidemiology Program at the School of Public Health, in the University of California at Berkeley; Honolulu Heart Study located in Honolulu, Hawaii; and the Atomic Bomb Casualty Commission that is located the cities of Hiroshima and Nagasaki, Japan. The funding is was awarded through grant No. 5 P01 NB06818 from the National Institute of Neurological Diseases and Stroke, Grant No. HL14783 from the National Heart and Lung Institute, the National Heart and Lung Institute Intramural Program, and the National Heart and Lung Institute made available to the Atomic Bomb Casualty Commission through the Atomic Energy Commission.
The authors of the study, R.
M. Worth, H. Kato, G. G. Rhoads, A. Kagan, and S. L. Syme, were trying to discover whether or not, if there were any reliable differences regarding the mortality rates from the causes of stroke or coronary heart disease (CHD) between Japanese American men that reside in Honolulu and San Francisco or Japanese men that reside in Hiroshima and Nagasaki. According to the study, the stroke, coronary heart disease (CHD) and total mortality were assessed from death certificates of Japanese men whose ages ranged from 45-64 years old that resided in Hiroshima and Nagasaki during the time period of 1965-1970, Honolulu during the time period of 1966-1970, and the San Francisco area during the time period of 1968-1972. The study examines the authentication of the fundamental causes of death by studying the death certificates of males who lived in Japan and Hawaii to determine what the statistics were, regarding the number of Japanese American males who died aged 45-64 years old. The study also examines the estimated error in death certification of coronary heart disease and stroke in Japan and Hawaii to monitor the detection rate and confirmation rate of Japanese American males who died from a stroke or a chronic health
disease.
The findings showed that the overall mortality rate was the highest in Japan, where there were not any differences in mortalities between Japanese American men that resided in Honolulu or San Francisco. The findings also showed that the death rates for American Japanese men who died as a result of having a stroke was equal to the amount of American Caucasian males that resided in the United States who were the same age as the Japanese American males, but were considerably worse compared to Japanese males who resided in Japan. In regards to the death rates of American Japanese men who died, as a result of having a coronary heart disease, the American Caucasian males was shown as being higher than the Japanese males who resided in the United States or Japan.
One of the limitations involved in the study is that as a result of the researchers utilizing a partial amount of cohorts in the study, the minute changes in stroke deaths that varied between Japan and the US, is statistically noticeable only in the 60-64 year age group.
However, it is constant with reports that have shown that wider age groups and males and female are all being utilized. Another one of the limitations involved in the study is how the researchers disregarded how serum cholesterol and glucose intolerance levels are related to thrombotic strokes. There may be an unknown environmental factor concerning those who had fatal strokes in Japan due to the major public health importance because even though the average amount of men who had serum cholesterol and whose glucose intolerance is the same of Japanese men who were residing in their native country, the average level of men who have serum cholesterol and whose glucose intolerance is greater in Japanese American men. Therefore, the amount of men who died of a stroke was lower if they decided not to migrate from Japan versus if they did migrate from Japan to Hawaii or
California.
