Hyperglycemia and type 2 diabetes among Filipino women in the Philippines, Hawaii, and San Diego.

BACKGROUND: Diabetes risk increases as immigrant populations adopt western lifestyles. We compared the prevalence of fasting hyperglycemia among Filipino women aged 40-79 years in the Philippines, Hawaii, and San Diego. METHODS: Data were obtained from the (1) Philippine National Nutrition Survey (1998), (2) Native Hawaiian Health Research Project (1997-2001), and (3) University of California San Diego Filipino Women's Health Study (1995-1999). Fasting glucose after an 8h fast, blood pressure, and body mass index (BMI) were measured in all three regions; a 75 g oral glucose tolerance test was performed in San Diego and Hawaii. RESULTS: The proportion of Filipinas with BMI > or = 30 kg/m2 was higher in Hawaii (20%) compared to women in San Diego (9.3%) or the Philippines (5.2%, p<0.001). Fasting hyperglycemia prevalence (fasting plasma glucose > or = 126 mg/dl or fasting whole blood glucose > or = 110 mg/dl) did not differ among Filipinas in the Philippines (11.8%), San Diego (14.1%), and Hawaii (14.7%, p = 0.323). Type 2 diabetes prevalence was similar among Filipinas in San Diego (31.6%) and Hawaii (24.9%, p = 0.79). CONCLUSIONS: Despite regional differences in obesity, fasting hyperglycemia was similar among Filipinas in the Philippines, San Diego, and Hawaii and type 2 diabetes prevalence was similar among Filipinas in San Diego and Hawaii.

A comparison of dietary habits among women in Japan and Hawaii.

OBJECTIVE: To compare the dietary habits of Japanese women in Japan with those of Japanese and Caucasian women living in Hawaii. DESIGN: Data from two previous cross-sectional studies conducted within two years in Hawaii and Gifu, Japan were pooled and analysed. Dietary intakes were assessed with validated food-frequency questionnaires and urine samples were collected for isoflavone measurement. SETTING: Participants were recruited through mammography clinics in both locations. SUBJECTS: In Hawaii, 164 Caucasian and 146 Japanese women; in Japan, 206 women. RESULTS: Dietary habits differed considerably by ethnicity and location. In comparison to the Caucasian diet, the diet in Japan was relatively low in fat and high in carbohydrates and protein, whereas the Japanese women in Hawaii reported intermediate intakes. Japanese women in Gifu consumed a diet that was relatively high in fish, soy, eggs and vegetables, and low in fruits, dairy products and meat. In contrast, the Caucasian women consumed the most dairy products and fruits and the Japanese women in Hawaii reported the highest grain and meat intakes. CONCLUSIONS: The diet of Japanese women in Hawaii appeared to be a combination of foods eaten in Japan and the dietary habits of Caucasian women in Hawaii, but eating habits in Japan are also different from traditional nutritional patterns. This study illustrates several problems related to dietary comparisons across populations and provides information for future investigations on chronic disease risk.

Near elimination of hepatitis B virus infections among Hawaii elementary school children after universal infant hepatitis B vaccination.

OBJECTIVES: Hawaii implemented routine infant hepatitis B vaccination in 1992 and required it for school entry in 1997. Previously, in 1989, a serologic survey among Hawaii school children in grades 1 to 3 indicated that 1.6% had chronic hepatitis B virus infection, and 2.1% had resolved infection. We conducted a follow-up survey to examine changes in hepatitis B virus infection rates. PATIENTS AND METHODS: This study was performed in Oahu, Hawaii, during the 2001-2002 school year among children in grades 2 and 3. Consenting parents/guardians provided demographic information including place of birth. Participants were tested for serologic evidence of hepatitis B virus infection and their vaccination status was determined by reviewing school records. Rates of symptomatic acute hepatitis B among persons aged < or = 19 years were calculated from cases reported from Hawaii to the Centers for Disease Control and Prevention between 1990 and 2004. RESULTS: Completed hepatitis B vaccination series were documented for 83% of the 2469 participants by age 18 months and for 97% by age 5 years. Past or present hepatitis B virus infection was detected among 6 participants (0.24%), including 1 (0.04%) with chronic infection and 5 (0.20%) with resolved infections. Compared with the 1989 survey, these prevalences represent declines of 97% and 90% in chronic and resolved hepatitis B virus infections, respectively. The incidence of symptomatic acute hepatitis B in Hawaii children and adolescents aged < or = 19 years decreased from 4.5 cases per 100,000 in 1990 to 0.0 during 2002-2004. To date, the last reported case in a child aged < 15 years in Hawaii occurred in 1996. CONCLUSIONS: Hepatitis B virus infection has nearly been eliminated in Hawaii children born after universal infant hepatitis B vaccination was implemented. These findings suggest that hepatitis B prevention goals are being met through routine immunization and related prevention programs among US children.

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.

The Hawaii Diet: ad libitum high carbohydrate, low fat multi-cultural diet for the reduction of chronic disease risk factors: obesity, hypertension, hypercholesterolemia, and hyperglycemia.

OBJECTIVE: The purpose of this study was to determine the health effects of a high carbohydrate, low fat multi-cultural traditional diet, The Hawaii Diet, fed ad libitum to an adult population. METHODS: Twenty-two adults recruited from various cultural backgrounds in Hawaii were fed, without calorie or portion size restriction, the Hawaii Diet for 21 days. The Hawaii Diet, based on familiar traditional foods from different cultures, is high in complex carbohydrate (77% of calories), low in fat (12% of calories), and moderate in protein (11% of calories). Participants were encouraged to eat to satiety. RESULTS: There was a significant weight loss on The Hawaii Diet averaging 10.8 lbs (23.8 kg) (P < .0001). Blood pressure was decreased from an average of 136.0/82.7 mm Hg to 125.5/78.9 mm Hg yielding a significant decrease of 10.4 mm Hg for systolic (P < .01). Beginning diastolic levels were normal so decreases in these values were not significant. Average lipid values also decreased with total serum cholesterol being significantly reduced from 205.3 to 156.9 mg/dl (P < .0001); LDL from 125.9 to 94.9 mg/dl (P < .001); and HDL from 38.3 to 31.3 mg/dl (P < .0005). Triglycerides (238.7 to 152.2 mg/dl) and the Chol:HDL ratio (5.8 to 5.2) improved at marginally significant levels (P < .08). There was also a significant reduction in blood glucose levels from 112.2 to 91.5 mg/dL (P < .01). CONCLUSION: The Hawaii Diet consisting of high carbohydrate, low fat ethnic meals appears to have a beneficial influence on weight loss and in decreasing systolic blood pressure, total cholesterol, LDL, and blood glucose values. Marginal improvement occurred for triglyceride levels. There was also a significant drop in HDL levels, however, the Chol:HDL was ratio did not increase. Further studies of longer duration with a control group should be conducted to test the effectiveness of The Hawaii Diet in maintaining these health benefits over a longer period of time.

Family-centered care: thriving in Hawaii under Part H.

Hawaii's system of prevention and early intervention embodies Part H principles that a child with a disability is first surrounded by a family, then by a community. Since 1986, families in Hawaii have been active in early intervention, first by persuading the governor to name the Department of Health as the lead agency, and then by writing much of the original grant application, interviewing and selecting staff members, and serving on the Hawaii Early Intervention Coordinating Council and its subcommittees. Families helped develop Hawaii's broad definition of the population to be served and were vocal advocates before the legislature to obtain funding for the program. Under Part H, Hawaii serves 6% of all children under the age of three, a larger percentage than any other state. Services focus on the family's needs as much as on the child's. The Individualized Family Support Plan (IFSP), developed jointly by the parents and professionals, recognizes families as the final decision-maker on the IFSP team. Families choose options that fit their needs. IFSP meetings are at times and places convenient to families and, to the extent feasible, in the family's native language. Care coordinators, of whom several are parents of children with special needs, monitor services to ensure that families receive quality care. Families receive (1) services at no cost, (2) preference when applying for positions in the Zero-to-Three Hawaii Project, and (3) compensation when serving in advisory or policy-making areas. In Hawaii, families are the center of early intervention services.

Avirulence gene avrRxv from Xanthomonas campestris pv. vesicatoria specifies resistance on tomato line Hawaii 7998.

The molecular and genetic control of the interaction between tomato races of Xanthomonas campestris pv. vesicatoria (XcvT) and tomato was studied. Based on inoculation phenotype and analysis of in planta bacterial growth, tomato line Hawaii 7998 is resistant to XcvT race 1 75-3 but not to XcvT race 2 89-1. Two cosmid clones from a genomic library of XcvT race 1 75-3 converted the normally virulent race 2 89-1 to avirulence on Hawaii 7998. The two clones contained the previously isolated, nonhost avirulence gene avrRxv, and their activity was localized to a 2.1-kbp subclone of avrRxv. avrRxv inhibits growth of race 2 89-1 in the resistant line Hawaii 7998 and an insertional mutation in avrRxv prevents this inhibition. In addition, a dramatic increase in electrolyte leakage of leaves of Hawaii 7998 occurred after 12-hr postinfiltration with race 2 89-1 carrying avrRxv. The nucleotide sequence of avrRxv revealed one major open reading frame (ORF) that accords well with activity analysis of nested deletions. ORF 2-2 encodes a putative protein of 374 amino acids with a molecular weight of 42.1 kDa and a pI of 10.7. Inheritance of the avrRxv-specific resistance in Hawaii 7998 was studied in a total of 587 F2 individuals from crosses between Hawaii 7998 and susceptible lines. The inheritance of avrRxv-specific resistance in Hawaii 7998 appears to be governed by more than one locus.

Kawasaki syndrome in Hawaii.

OBJECTIVE: To describe the incidence and epidemiology of Kawasaki syndrome (KS) in Hawaii. METHODS: Retrospective analysis of the State Inpatient Database for Hawaii residents hospitalized with KS during 1996 through 2001. RESULTS: During 1996 through 2001, 267 persons younger than 18 years of age living in Hawaii were hospitalized with KS; 226 (84.6%) were younger than 5 years of age. The average annual incidence for KS was 45.2 per 100,000 children younger than 5 years of age. The incidence was higher for children younger than 1 year of age than for those 1-4 years of age (74.3 and 37.5 per 100,000). The KS incidence for Asian and Pacific Islander children and for White children was 70.9 and 35.3 per 100,000, respectively. Incidence was highest among Japanese American children living in Hawaii (197.7 per 100,000). Honolulu County had the most KS patients (85.0%) and the highest incidence (53.1 per 100,000) among Hawaii counties. For children younger than 5 years of age hospitalized with KS, the median length of stay was 2 days, and the median hospital charge was $9379. CONCLUSION: During 1996 through 2001, the annual incidence rate for KS among children younger than 5 years of age in Hawaii was the highest in the United States. The incidence among Japanese American children in Hawaii was higher than that among other racial groups in the state and when compared with children living in Japan.

Descriptive epidemiology of thyroid cancer in Hawaii.

Data were analyzed from 1110 thyroid cancer cases between 1960 and 1984 identified by the Hawaii Tumor Registry, a population-based Statistics, Epidemiology and End Results (SEER) participant covering the entire state of Hawaii. Incidence rates for men and women were relatively stable during this 25-year period. The overall age-adjusted rates were 8.1 per 100,000 for women and 3.1 per 100,000 for men. There was a significant variation in incidence on the basis of ethnicity, with the highest rates for women occurring in Filipinos (18.2 per 100,000) and for men in Chinese (6.3 per 100,000). A comparison of different populations around the world showed that Hawaii has some of the highest reported incidence rates for thyroid cancer. In addition, a comparison of ethnic-specific incidence rates for groups living in Hawaii with people of the same ethnic backgrounds living in other geographic areas showed that Hawaii residents generally have much higher rates, suggesting that environmental influences are responsible for the unusually high rates in Hawaii.

Inter- and intra-ethnic differences for female breast carcinoma incidence in the continental United States and in the state of Hawaii.

BACKGROUND: Ethnic diversity is well-documented for female breast carcinoma incidence in the continental US but is not so well-established in the state of Hawaii. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) program, we analyzed n=323,607 in situ and invasive female breast cancer cases for major ethnic groups in the continental US and in Hawaii, diagnosed during the years 1992-2002. RESULTS: In the continental US, age-specific incidence rate patterns and prognostic factor profiles were good-risk for Asian or Pacific Islanders (API), intermediate for Whites, and poor-risk for Blacks. For example, early age-at-onset, high nuclear grade, aggressive histopathologic subtypes, and hormone receptor negative expression was associated with Black race in the continental US. In Hawaii, age-specific rate and prognostic profiles were more favorable for API than for White women, albeit not so striking as in the continental US. CONCLUSION: We observed inter- and intra-ethnic differences for female breast carcinoma in the continental US and in the state of Hawaii. While inter-racial disparities were expected, intra-racial differences were somewhat unexpected and possibly due to variations in racial subgroup mixing and/or cultural assimilation. For example, API women with breast carcinoma in the continental US included 96.03% Asians and 2.4% Pacific Islanders. In contrast, API women with breast carcinoma in Hawaii included 76.52% Asians and 23.46% Pacific Islanders. Moreover, APIs were more likely to be first-generation migrants in the continental US ( approximately 92%) than in Hawaii ( approximately 34%). Future studies should attempt to disaggregate racial data to separately characterize epidemiological patterns for individual ethnic groups.

Breast cancer survival among Hawaii Japanese and Caucasian women. Ten-year rates and survival by place of birth.

Unlike past breast cancer survival comparisons between Japan and the United States, a recent study in Hawaii showed that Japanese women did not retain their survival advantage over Caucasian women after adjustment was made for stage at diagnosis. To test whether this finding in Hawaii was due to the limited duration of the follow-up (five years) or to the effects of migration, the survival experience of 1,357 Caucasian and 1,029 Japanese women with invasive breast carcinoma diagnosed in Hawaii between 1960 and 1979 was examined over a 10-year period as well as by place of birth. Multivariate adjustment by the proportional hazards regression model confirmed that the survival advantage of Japanese women in Hawaii is fully explained by their earlier stage of disease at diagnosis and suggested that, after recognition, the disease progresses at a similar pace in the two races. The survival comparison by place of birth revealed that second generation Hawaii Japanese women had better breast cancer survival rates than Japanese migrants from Japan, even after adjusting for stage, and that for Caucasian women, nativity was not associated with survival. These findings suggest that westernization, genetic constitution, or early life exposures cannot explain the overall or stage-adjusted breast cancer survival patterns observed among Caucasian and Japanese women in Hawaii.

Prevalence of joint pain is higher among women in rural Japan than urban Japanese-American women in Hawaii.

OBJECTIVE: Environmental factors such as farming contribute to the frequency of joint symptoms. The purpose of this study is to explore the possible role of environment (lifestyle), by comparing the prevalence of joint pain between Japanese in a rural farming district in Japan and in urban Hawaii. SUBJECTS AND METHODS: Current or previous pain at specific joints was surveyed among 222 women in rural Japan and 638 Japanese women in urban Hawaii aged 60-79. The age adjusted prevalence was compared using logistic regression. RESULTS: The prevalence of pain at one or more joints was approximately 70% in Japan and 50% in Hawaii. The prevalence of knee pain in Japan ranged from 36% at ages 60-69 years to 53% at 70-79 years (mean 41%), whereas knee pain affected only 20% of women in Hawaii in both age groups. The odds ratio (and 95% CI) was 3.2 (2.1, 4.8) for knee pain, and 4.0 (2.2, 7.4) for mid-back pain in Japan, compared with Hawaii. Pain was also significantly more common in Japan at the shoulder, elbow, and ankle, but not at other joints. Women in Japan were shorter and weighed less than in Hawaii. Adjustment for body mass index increased the odds ratios to 4.4 (2.9, 6.8) for knee, and 4.5 (2.4, 8.5) for mid-back pain. CONCLUSION: Although the potential influence of cultural factors or other sources of bias cannot be ruled out, the large differences in the prevalence of pain at specific joints suggest that environmental factors are probably responsible, because both populations are of similar genetic stock.

Seasonal variation of sudden infant death syndrome in Hawaii.

OBJECTIVE: To test whether the sudden infant death syndrome (SIDS) rate displays the universal winter maximum and summer minimum in Hawaii where there is no appreciable seasonal variation of temperature. DESIGN: The null hypothesis is tested that there is no seasonal variation of necropsied SIDS in Hawaii. The numbers of live births and SIDS cases by month for the years 1979 to 2002 were collected and the monthly SIDS distribution is predicted based on the age at death distribution. SETTING: The state of Hawaii, located in the midst of the Pacific Ocean, has a semi-tropical climate with temperatures fluctuating diurnally as 25 +/- 5 degrees C throughout the year. Therefore homes are unheated and infants are not excessively swaddled. The Hawaii State Department of Health maintains vital statistics of all infant births and deaths. MAIN RESULTS: The results reject the null hypothesis of no seasonal variation of SIDS (p = 0.026). An explanation for the seasonal effect of the winter maximum and summer minimum for Hawaiian SIDS is that it arises from the cycle of the school session and summer vacation periods that represent variable intensity of a possible viral infection vector. SIDS rates in both Hawaii and the United States increase with parity, also indicating a possible role of school age siblings as carriers. CONCLUSIONS: The winter peak of the SIDS in Hawaii is support for the hypothesis that a low grade viral infection, insufficient by itself to be a visible cause of death at necropsy, may be implicated as contributing to SIDS in vulnerable infants.

Melanoma and Hawaii's youth.

Hawaii's sandy beaches, warm crystal waters, and mild climate attract tourists and residents alike to enjoy hours of outdoor activities under the sun. As frequent participants of these sun related activities, Hawaii's youth are exposed to high levels and duration of ultraviolet radiation throughout their early lives. This study aims to define occurrence trends of cutaneous malignant melanoma in Hawaii in correlation to increased childhood ultraviolet exposure. This paper addresses trends in melanoma incidence during 1979-2002 for Hawaii residents < 25 years of age. Data obtained from this review were analyzed by age group and ethnicity. Results show that although the incidence of melanoma is increasing for Hawaii residents over 25 years of age, the rate of melanoma occurrence in Hawaii's youth (< 25 years) is not increasing.

AANCART comes to Hawaii.

There are 176,707 foreign-born Asian Americans living in Hawaii, according to the 2000 Census. Data from the Hawaii Tumor Registry show that foreign-born Asian Americans in Hawaii are diagnosed with cancer at a later stage than the white population in Hawaii. It is the intent of AANCART at the Cancer Research Center of Hawaii to address this disparity of cancer status of the foreign-born Asian American population in Hawaii.

Leptospirosis in Hawaii: shifting trends in exposure, 1907-1984.

Leptospirosis was first recognized as an occupational disease of sugar plantation workers in Hawaii in 1907. Since then, shifts have been noted in the animal transmission cycles, the occupational groups at risk, and an increasing recognition of cases associated with avocational exposure. Surveys of the small mammal populations indicate rats, mice, and mongooses are the most important vectors in Hawaii. Serologic surveys of workers in high-risk occupations show antibody prevalence rates ranging from 12 to 82 percent. The epidemiology of leptospirosis in Hawaii is described, based on 182 cases reported to the Hawaii Department of Health from 1970-1984. The most common infecting serovar was mankarso in the Icterohaemorrhagiae serogroup; other serovars in the Icterohaemorrhagiae group were also frequently implicated as causing disease. The manifestations of disease noted by physicians in Hawaii are similar to those observed in the continental U.S. Fever, myalgia, and headache were the most common symptoms reported in the majority of cases in Hawaii; jaundice was noted in the records of 24 percent. Recommendations made to interrupt the cycle of transmission and reduce the chances of exposure in occupational settings include the control of rodent populations and vaccination of domestic animals. Personal hygiene among workers is to be encouraged, and the development of prophylactic measures is suggested either by immunization or by chemoprophylaxis.

A comparison of the prevalence and risk factors of high blood pressure among Japanese living in Japan, Hawaii, and Los Angeles.

THE AUTHORS STUDIED THE PREVALENCE AND RISK FACTORS of hypertension in samples of 2053 Japanese ages 40 to 70 in Hiroshima, Hawaii, and Los Angeles. The prevalence of hypertension (systolic blood pressure greater than or equal to 140 mmHg, diastolic blood pressure greater than or equal to 90 mmHg, or receiving antihypertensive drug treatment) was higher in Hawaii and Los Angeles for both sexes and almost all ages than in Hiroshima. The age- and sex-adjusted prevalence of hypertension in Hawaii, Los Angeles, and Hiroshima was 42.6%, 37.2%, and 29.7%. Hypertension was associated with a significant elevation in serum glucose, insulin, triglyceride, and total cholesterol levels in the combined participant population of Hawaii, Los Angeles, and Hiroshima. Age- and sex-adjusted mean values of serum total cholesterol, triglyceride, and insulin were highest in Hawaii and lowest in Hiroshima. The mean body mass index and 2-hour serum glucose levels were greatest in Hawaii and equal in the two other cohorts. These results suggest that hyperinsulinemia and hyperlipidemia may explain the prevalence of hypertension in the research participants.

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.
