Epidemiologic studies of coronary heart disease and stroke in Japanese men living in Japan, Hawaii and California. Coronary heart disease risk factors in Japan and Hawaii.

Various risk factors were evaluated to explain a significantly greater incidence of coronary heart disease in men of Japanese ancestry resident in Hawaii compared with men resident in Japan. The independent predictors of incidence of coronary heart disease in both Japan and Hawaii were systolic blood pressure, serum cholesterol, relative weight and age. These factors appeared to influence incidence similarly in both areas because in each case the correlation coefficients for Japan and Hawaii did not differ significantly. The hypothesis that the greater incidence in Hawaii could be attributed to differences in levels of these risk factors was tested with the Walker-Duncan method. The four variable multiple logistic function describing the probability of coronary heart disease in Japan was applied to the cohort characteristics observed in Hawaii. The estimated incidence thus obtained was not significantly different from that actually observed in the men resident in Hawaii. Therefore the increased coronary risk profile in Hawaii compared with Japan can account for the greater incidence of coronary heart disease in the former. Current cigarette smoking was significantly related to the risk of coronary heart disease in Hawaii but not in Japan. This difference requires further investigation.

Diabetes mellitus and its vascular complications in Japanese migrants on the Island of Hawaii.

Japanese migrants and their offspring on the island of Hawaii and Japanese living in Hiroshima were examined for diabetes mellitus and its vascular complications. the same methods and investigators were used in both locations. Death certificates of Japanese and Caucasians dying on the island during the past 26 yr were analyzed. Diabetes, defined as a venous serum glucose concentration of at least 200 mg/dl 2 h after a 50-g oral glucose load, was significantly more common in the Hawaiian Japanese than in the Hiroshima Japanese subjects. This suggests that diabetes is more prevalent in Japanese in Hawaii than in Japan, although lack of knowledge about the total population of Japanese migrants in Hawaii makes this generalization uncertain. The proportion of deaths attributed to diabetes was much higher in Japanese migrants and their offspring in Hawaii than in Japan. During the 1950s, the proportional death rate from diabetes was about half as large in Japanese Hawaiians as in Caucasian Hawaiians, but it increased to become 1.6 times the Caucasian rate during the 1970s. A nutritional study revealed that the total caloric intake was similar in Japanese in Hawaii and Hiroshima, although the estimated level of physical activity was less in the Hawaiian subjects. Consumption of animal fat and simple carbohydrates (sucrose and fructose) were at least twice as high in Hawaiian as in Hiroshima Japanese. Conversely, Hiroshima Japanese consumed about twice the amount of complex carbohydrate as the Hawaiian Japanese. These observations support the hypothesis that a high fat, high simple carbohydrate, low complex carbohydrate diet and/or reduced levels of physical activity increase risk of diabetes. The proportion of deaths attributed to ischemic heart disease was higher in both diabetic and nondiabetic Japanese Hawaiians than in diabetic subjects in Japan. The rates were similar for Japanese and Caucasians in Hawaii. There was no evidence of an environmental influence on the development of microangiopathy (retinopathy) in diabetes, as the prevalence of diabetic retinopathy (stratified for diabetes duration) was similar in Japanese subjects in Hawaii and in Japan, and it was similar to previous reports from England. On the other hand, diabetes alone did not appear to account for the greater prevalence of macroangiopathy in Hawaiian Japanese than in Hiroshima. Thus environmental factors, possibly including diet, appear to be involved in the development of macrovascular complications of diabetes.

Frequency of systemic lupus erythematosus in different ethnic groups in Hawaii.

A survey of systemic lupus erythematosus (SLE) patients was conducted in civilian general hospitals on Oahu, Hawaii for the years 1970-75. One hundred sixty-eight cases were ascertained, of which 107 were considered "definite." Age-adjusted prevalence rates per 100,000 were estimated for definite cases at the end of 1975 as follows: white 5.8, Chinese 24.1, Filipino 19.9, part-Hawaiian 20.4, and Japanese 18.2. There was a heavy preponderance of females in each ethnic group, averaging 90% of the definite cases overall. Review of vital statistics for the United States and Hawaii during this period showed age-adjusted SLE mortality rates per million as follows: U.S. white 3.04, U.S. non-white 8.82, Hawaii white 1.89, Hawaii non-white 14.46. The cause of the very high SLE prevalence and mortality in the Oriental and Polynesian people of Hawaii is not clear.

The Hawaii Medical Fellowship Mission to China.

The Hawaii Medical Fellowship Foundation is a non-profit Hawaii corporation to provide and exchange medical fellowship, knowledge, care, cooperation and service, and to support other humanitarian causes here in Hawaii and abroad. The Foundation plans a mission to China in October 1991. Hawaii physicians, at their own expense and time, will be spending a week in Shantou, China, providing medical service to and sharing techniques with their Chinese counterparts. The Foundation also plans to establish scholarships for students in Hawaii who wish to pursue health careers and to establish clinic/health fairs for the immigrants. It is willing to entertain ideas and suggestions for additional projects.

Pneumococcal bacteremia in Hawaii: initial findings of a pneumococcal disease prevention project.

The Hawaii Department of Health (DOH) recently established a pneumococcal disease initiative to determine the scope of serious pneumococcal disease in residents of Hawaii and to investigate methods of increasing vaccine utilization in the State. The initial phase of the project involved a review of pneumococcal bacteremia at all 38 microbiology laboratories in Hawaii during 1986 and 1987. Two hundred twenty-two residents with bacteremia were identified. Eighty-six percent of adults had pneumonia as the primary source of bacteremia. In children greater than 5 years old, pneumonia was present in 24%, otitis media in 35%, and meningitis in 11%. Bacteremia with no apparent focus of infection was found in 30% of children. The overall annual incidence of pneumococcal bacteremia was 9/10(5) population. Rates were highest in children greater than 2 years old (103/10(5] and persons greater than or equal to 65 years old (22/10(5]. These are similar to rates reported from other populations in the United States during the 1970s and early 1980s, but are less than those detected in 2 more recent population-based studies. The overall case-fatality rate in our study was relatively low (16%); however, 35% of persons greater than or equal to 65 years old died. A record of previous pneumococcal vaccination was found in the medical records of only 2 (1%) patients. Our study confirms that pneumococcal bacteremia causes significant morbidity and mortality among elderly residents of Hawaii and suggests that vaccine coverage is very low among this high-risk population. Phase 2 of the initiative included surveys of Hawaii physicians and the public to ascertain attitudes toward pneumococcal immunization.(ABSTRACT TRUNCATED AT 250 WORDS)

Gastrointestinal carcinoma in the Japanese of Hawaii: a status report.

The primary aim of the Japan--Hawaii Cancer Study was to identify factors that could explain the changes in cancer risk experienced by Japanese who migrated to Hawaii. Many investigations were conducted in this long-term prospective study since its inception in 1971. Among the findings that relate to gastrointestinal carcinoma were the following: 1) Bowel transit time does not appear to be related to the occurrence of large bowel cancer or to any of the benign conditions with which it is associated; 2) adenomatous and hyperplastic polyps, as well as diverticula, are much more prevalent among autopsy specimens from Japanese who had lived in Hawaii than of those in Japan; 3) adenomatous polyps and diverticula are positively associated with atherosclerosis in the necropsy population in Hawaii; 4) although the incidence of the diffuse histopathologic type of gastric cancer does not differ appreciably among the Japanese in Hawaii and Japan, the migrants have a significantly lower incidence of the intestinal type of stomach cancer; and 5) case-control studies indicated that the two conditions frequently associated with gastric carcinoma, i.e., gastric ulcer and intestinal metaplasia of the stomach, are associated with high salt intakes and adherence to the traditional Japanese diet.

Breast cancer in multi-ethnic populations: the Hawaii perspective.

The five major ethnic groups in Hawaii's population of 1.1 million are the Japanese, comprising 23%; Caucasians, 23%; ethnic Hawaiians, 19.9%; Filipinos, 11.3%; and Chinese, 4.8%. Only 14% of the population is foreign born. Breast cancer incidences are 29.2 per 100,000 among Filipinos, 51.3 for Japanese, 64.1 for Chinese, 104.3 for Hawaiian, and 105.6 for Caucasian women. The Caucasian incidence is similar to mainland US rates, but the incidence among Hawaii's Japanese is more than twice the rate in Japan. Japanese in Hawaii have less postmenopausal breast cancer than Caucasians, fewer axillary lymph node metastases, and a greater proportion of non-invasive tumors. Late stage at diagnosis is common among Filipino and ethnic Hawaiian woman, and their risk of death is 1.5-1.7 times that of Caucasian, Chinese, and Japanese women with the disease, even after adjustment for age, extent of disease, and socio-economic status. In the BCDDP screening study, only 20% of breast cancers detected in ethnic Hawaiians were not yet palpable and were found by mammography alone. Comparative studies of diet and estrogen levels in the ethnic groups of Hawaii and the parental populations in Japan and the West do not account for the degree of variation observed in breast cancer incidence and tumor pathology. Future research directions are suggested with a view to accounting for these differences.

Epidemiologic studies of coronary heart disease and stroke in Japanese men living in Japan, Hawaii and California. Incidence of myocardial infarction and death from coronary heart disease.

The incidence of myocardial infarction and death from coronary heart disease was studied in defined samples of 45 to 68 year old Japanese men in Japan, Hawaii and California. The incidence rate was lowest in Japan where it was half that observed in Hawaii (P less than 0.01). The youngest men in the sample in Japan were at particularly low risk. The incidence among Japanese men in California was nearly 50 percent greater than that of Japanese in Hawaii (P less than 0.05). A striking increase in the incidence of myocardial infarction appears to have occurred in the Japanese who migrated to the United States; this increase is more pronounced in California than in Hawaii.

Epidemiologic studies of coronary heart disease and stroke in Japanese men living in Japan, Hawaii and California: prevalence of coronary and hypertensive heart disease and associated risk factors.

A study of coronary heart disease (CHD) among Japanese migrants compared with Japanese living in Japan provided the opportunity to study factors possibly responsible for the high rates of CHD in America as compared with Japan. Comparable methods were employed in examining 11,900 men of Japanese ancestry aged 45--69 living in Japan, Hawaii and California. The age-adjusted prevalence rates for definite CHD as determined by ECG were: Japan 5.3, Hawaii 5.2 and California 10.8/1000. For definite plus possible CHD the rates were 25.4, 34.7 and 44.6. The prevalence of angina pectoris and pain of possible myocardial infarction, determined by questionnaire, showed a similar gradient. Elevated serum cholesterol showed a Japan-Hawaii-California gradient, but the prevalence of hypertension in Japan was intermediate between the prevalence in Hawaii and the higher prevalence in California. The three geographic locations were compared as to prevalence of CHD at comparable levels of blood pressure and cholesterol. At each blood pressure level and at each cholesterol level, the greater prevalence of CHD in California persisted. These facts, plus the near universality of smoking in Japan, suggest that conventional risk factors only partly explain the observed gradient in CHD.

Primary antituberculous drug resistance in Hawaii, 1957 to 1977.

A study of primary antituberculous drug resistance in Hawaii was conducted from 1957 to 1977 to determine the incidence of primary resistance with respect to time. A total of 1,869 initial cultures of Mycobacterium tuberculosis submitted to Leahi Hospital in Honolulu were screened to identify drug resistance. Of 256 patients who excreted resistant bacilli, only 55 had no history of previous antituberculous chemotherapy. The frequencies of primary drug resistance from July 1957 to July 1977 were as follows: streptomycin, 0.86 per cent; isoniazid, 1.2 per cent; para-aminosalicylic acid, 1.5 per cent. No strains were resistant to ethambutol or rifampin. A slight decrease in the incidence of drug resistance during a 20-year period was observed. This was especially significant because Hawaii's tuberculosis problem is principally confined to its foreighn-born population. Although no serious primary drug resistance problem was discovered, Hawaii possesses both the highest immigration rate and the highest incidence of tuberculosis in the United states. Therefore, there is a need for continued periodic monitoring of drug resistance in Hawaii.

Health status and lifestyle in elderly Hawaii Japanese and Australian men. Exploring known differences in longevity.

OBJECTIVE: To contrast health status and lifestyle in two elderly populations with differing longevity. DESIGN: Comparison of two cross-sectional data sets. SETTING: Non-institutionalised subjects. SUBJECTS: Men aged 60-81 years resident in Dubbo, New South Wales (n = 1183, 1988-1989) and Japanese men of the same ages resident in Hawaii (n = 1376, 1980-1982). MAIN OUTCOME MEASURES: Cardiovascular and non-cardiovascular disease prevalence, risk factors, social and health status. RESULTS: A history of heart attack, angina and stroke was twice as prevalent in Dubbo men as in Hawaii Japanese. Other diseases were many times more prevalent in Dubbo--liver disease sixfold, prostate and renal disease twofold, and arthritis 1.5-fold. Hypercholesterolaemia and untreated hypertension were more prevalent in Dubbo (threefold and 1.5-fold respectively). Current smoking was similar in both groups, while diabetes was twice as prevalent in the Hawaii Japanese. More Dubbo men were widowed or lived alone, and fewer remained in paid employment. Dubbo men had more limited physical mobility. CONCLUSIONS: Elderly Dubbo men have an excess of cardiovascular disease and associated risk factors, as well as an excess of non-cardiovascular disease, compared with Hawaii Japanese. This may account, in part, for a higher total mortality rate in elderly Australians compared with Japanese. Some of this disease burden may be amenable to risk factor intervention.

Colon cancer: its precursors and companions in Hawaii Japanese.

Following migration to Hawaii, the Japanese have acquired the same risk of developing large bowel cancer as that experienced by Caucasians. This tumor is uncommon in Japan. Other conditions are also more common in Hawaii Japanese, e.g., myocardial infarction, severe atherosclerosis, diverticulosis, and polyposis of the colon. Comparative studies in Hawaii and Japan suggest that the basis of these differences is probably related to the consumption of characteristically western foods by Hawaii Japanese.

Hospitalizations for hip fractures among elderly persons in Hawaii, 1986-1990.

Hawaii differs ethnically, geographically, and culturally from other states; therefore, United States hip fracture data cannot be assumed to apply to Hawaii. The purpose of this research was to gain new knowledge about hip fracture in Hawaii to plan and target appropriate services and design preventive measures. Peer Review Organization Medicare data were analyzed for persons age 65+ over a 4-year period. Average length of hospital stay was 20 days resulting in an average estimated charge per hospitalization of $20,000. Of those with E-Codes, 94% sustained falls. Fifty-five percent had one or more complicating illness. Unexpected significant differences were found among the islands: the average annual hospitalization incidence rate/1,000 on Kauai (8.4) was almost twice that of the Island of Hawaii (4.4), and Maui (3.9), and significantly greater than Oahu (5.4), primarily in women over 85. The island differences raise important questions in need of investigation, and suggest target populations and locations for prevention.
