Box jellyfish (Carybdea alata) in Waikiki. The analgesic effect of sting-aid, Adolph's meat tenderizer and fresh water on their stings: a double-blinded, randomized, placebo-controlled clinical trial.

The study measured the analgesic effects of three popular Hawaii remedies for stings from the box jellyfish, Carybdea alata. Analysis of data showed that aerosol sprays of Sting-Aid (an aluminum sulfate solution), Aldolph's meat tenderizer dissolved in water, and fresh water neither increased nor decreased the pain of box jellyfish stings more than the control (seawater).

Box jellyfish (Carybdea alata) in Waikiki: their influx cycle plus the analgesic effect of hot and cold packs on their stings to swimmers at the beach: a randomized, placebo-controlled, clinical trial.

The study measured the analgesic effect of hot and cold packs on box jellyfish (Carybdea alata) stings to Waikiki swimmers at the beach. Analysis of data showed a minimal trend toward pain relief 10 minutes after the application of hot packs, particularly when the initial pain was mild to moderate. Cold packs showed no clinically significant relief of pain, compared to the control. Data tracking shows that most box jellyfish appear in Waikiki waters on the 9th or 10th day after the full moon.

A longitudinal study of drinking and cognitive performance in elderly Japanese American men: the Honolulu-Asia Aging Study.

OBJECTIVES: This study prospectively describes the relationships between alcohol intake and subsequent cognitive performance among participants in the Honolulu Heart Program (HHP). METHODS: Alcohol intake was assessed at Exam III of the HHP, and cognitive performance was measured approximately 18 years later with the Cognitive Abilities Screening Instrument (CASI). Complete information was available for 3556 participants, aged 71 to 93 years at follow-up. RESULTS: In multivariate analyses, the relationship between drinking and later cognitive performance appeared nonlinear, as nondrinkers and heavy drinkers (more than 60 ounces of alcohol per month) had the lowest CASI scores and the highest risks of poor and intermediate CASI outcomes. Compared with nondrinkers, the risk of a poor CASI score was lowered by 22% to 40% among men who consumed 1-60 ounces of alcohol per month. CONCLUSIONS: We report a positive association between moderate alcohol intake among middle-aged men and subsequent cognitive performance in later life. However, it is possible that the health risks associated with drinking outweight any potential benefits for many elderly persons.

Dietary intake of modernizing Samoans: implications for risk of cardiovascular disease.

OBJECTIVE: To describe the dietary intake of American and Western Samoans, with emphasis on nutrients conventionally related to risk factors for cardiovascular disease. DESIGN: Cross-sectional dietary survey. Intake estimates were based on 24-hour recall interviews. SUBJECT: Community-based samples of 946 men and women (455 American Samoans, 491 Western Samoans) aged 25 to 55 years. STATISTICAL ANALYSES: Tests of differences in means (t tests) and proportions (chi 2 tests). Correlation and multivariate linear regression analyses were conducted to describe correlates of energy and nutrient intakes. RESULTS: Few differences were noted between the energy and nutrient intakes of men and women, but substantial differences were found between residents of American Samoa and those of the less modernized country of Western Samoa. American Samoans consumed significantly more energy as carbohydrate (47% vs 44%) and protein (18% vs 13%) and less as fat (36% vs 46%) and saturated fat (16% vs 30%). Energy-adjusted intakes of cholesterol and sodium were higher among American Samoans. These differences persisted after adjustment for age, gender, years of education, occupation, and categories of a 10-point material lifestyle score. Samoans in the lowest category of material lifestyle had significantly lower energy-adjusted intakes of protein, cholesterol, and sodium and higher intakes of saturated fat than those in the upper 2 categories. Additional analyses described the contribution of specific foods to the intakes of energy and macronutrients. CONCLUSIONS/APPLICATIONS: The observed energy and nutrient intake patterns are consistent with previously reported levels of obesity and risk factors for cardiovascular disease among Samoans and suggest dietary modification for those at highest risk. Dietetics practitioners who counsel Samoan and other Pacific Islander clients should be aware of these intake patterns, which seem particularly malleable to levels of personal income. More generally, results from this study illustrate that the food choices of certain ethnic groups may be profoundly affected by the process of modernization within a country or by migration to a more economically developed locale.

Intakes of selected foods and beverages and the incidence of gastric cancer among the Japanese residents of Hawaii: a prospective study.

BACKGROUND: We report on the associations between the intake of certain foods and beverages and the incidence of gastric cancer in a cohort of 11,907 randomly selected Japanese residents of Hawaii (6297 women and 5610 men). METHODS: The daily intake of six beverages, cigarettes and alcohol and the weekly frequency of intake of 13 foods and food groups was estimated with a short food frequency questionnaire. Over an average follow-up period of 14.8 years, 108 cases of gastric cancer (44 women, 64 men) were identified via linkage to the Hawaii Tumor Registry. RESULTS: In gender-combined proportional hazards analyses, the consumption of fresh fruit seven or more times per week was associated with a significantly reduced risk of gastric cancer, compared to lower levels of consumption (relative hazard (RH): 0.6, 95% confidence interval (CI): 0.4-1.0, P = 0.03). The combined intake of fresh fruit and raw vegetables was inversely associated with the risk of gastric cancer in the total cohort, and among the men (P < 0.05). No significant relationships were found between gastric cancer incidence and the intake of pickled vegetables, miso soup, dried or salted fish, or processed meats among either gender. Compared to non-drinkers, men who drank one cup of coffee per day had a significantly elevated risk of gastric cancer (RH: 2.5, 95% CI: 1.0-6.1, P = 0.05), but there was no evidence of a dose-response relationship. Cigarette smoking and consumption of alcohol were not related to gastric cancer, in analyses restricted to the men. CONCLUSIONS: The results related to fruit and vegetable intake are consistent with an anti-nitrosating effect of these foods, while the unexpected association between coffee consumption and gastric cancer is difficult to explain and may represent a chance finding.

Anthropometric predictors of breast cancer incidence and survival in a multi-ethnic cohort of female residents of Hawaii, United States.

OBJECTIVES: The purpose of the study was to describe the associations between height and body mass index (BMI) (wt/ht2) and breast cancer incidence and survival among female residents of Hawaii. METHODS: The study sample is a randomly-selected, multi-ethnic cohort of 17,628 women. A total of 378 incident breast cancer cases were identified via linkage to the Hawaii Tumor Registry over an average follow-up period of 14.9 years. Using age 50 as a cut-point, 86 were considered premenopausal cases, and 292 were postmenopausal. Proportional hazards analysis was used to describe the risks associated with height and BMI, after adjustment for age, education, race/ethnicity, and drinking status. For mortality analyses, there were 34 breast cancer deaths among the 365 breast cancer cases for which staging information was available. RESULTS: The risk of postmenopausal breast cancer was found to increase progressively across approximate tertiles of the distribution of height (P = 0.02 for trend test), with a significantly excess risk among women in the tallest tertile (risk ratio [RR] = 1.5, 95 percent confidence interval [CI] = 1.1-2.1). Baseline levels of BMI were related positively to breast cancer incidence among postmenopausal women, after control for the above covariates (P = 0.01 for trend test). Among postmenopausal women in the highest quintile of the BMI distribution, the RR was 1.5 (CI = 1.0-2.3, P = 0.04). Further analyses indicated the association between BMI and postmenopausal breast cancer incidence was strongest among women aged 65 years and older. After statistical control for the above covariates and stage of disease, pre-morbid levels of BMI were significantly predictive of death from breast cancer, with an approximate nine percent increase in risk per unit increase in BMI (P = 0.01). Compared with women in the lowest two quartiles, the RR among the heaviest women was 2.2 (CI = 0.9-5.4,P = 0.08). Height was not associated with risk of breast cancer mortality. CONCLUSIONS: Relative weight may be an important modifiable risk factor for both breast cancer incidence and prognosis. The association between height and breast cancer incidence is more difficult to interpret, but may underscore the importance of early life exposures in the development of breast cancer.

Relative weight, weight change, and risk of coronary heart disease in the Honolulu Heart Program.

Risk of coronary heart disease (CHD) among the Honolulu Heart Program participants was examined in relation to body mass index (BMI) at age 25 and two subsequent periods of weight change: age 25 to examination I (1965-1968) and examination I to examination III (1971-1974). During a maximum follow-up period of 17 years after examination III, there were 479 incident cases of CHD among the study sample of 6,176 Japanese-American men. Levels of BMI at age 25 were positively related to CHD incidence after statistical control for age, smoking, and subsequent weight change. Relative risk between the lowest and highest BMI categories was 2.44 (95% confidence interval (CI) 1.61-3.69). Compared with a weight change of less than 2.5 kg between age 25 and examination I, relative risks were 1.41 (95% CI 1.00-1.97) for a weight gain between 2.6 and 5 kg, 1.60 (95% CI 1.22-2.11) for a weight gain between 5.1 and 10 kg, and 1.75 (95% CI 1.32-2.33) for a weight gain of more than 10 kg. During the examination I-III period, in contrast, the highest risk of CHD was found in men who lost the greatest amount of weight; the relative risk of CHD for men who lost more than 2.5 kg was 1.25 (95% CI 0.98-1.60). The authors conclude that levels of relative weight in early adulthood were positively related to risk of CHD occurring much later in the lives of these men. The association between CHD incidence and weight change appeared to be modified by age, with higher risks for earlier weight gain and later weight loss in the lives of these men.

Smoking history in middle age and subsequent cognitive performance in elderly Japanese-American men. The Honolulu-Asia Aging Study.

The associations between cigarette smoking history and later cognitive performance were examined among 3,429 Japanese-American participants of the Honolulu Heart Program (HHP) and its extension, the Honolulu-Asia Aging Study (HAAS). Cognitive performance was measured by the Cognitive Abilities Screening Instrument (CASI), administered as part of HAAS (mean age at HAAS exam (standard deviation (SD)): 77.7 (4.6) years). Information on smoking history was collected during the first and third HHP exams (mean age (SD) at Exam III: 58.6 (4.7) years). Compared with never-smokers, those who had smoked continuously between Exams I-III and those who had quit smoking during that period had significantly lower CASI scores, after adjustment for age, education, Japanese acculturation, and Exam III alcohol intake. In multiple logistic regression controlling for the above covariates, a significantly higher risk of cognitive impairment (CASI score < 82) was associated with continuous smoking (odds ratio (OR) = 1.36, 95% confidence interval (CI) 1.10-1.69) and quitting between Exams I-III (OR = 1.36, 95% CI 1.03-1.80) compared with never smoking. This excess risk of cognitive impairment among continuous smokers and Exam I-III quitters was slightly diminished by further adjustment for body mass index and several vascular covariates. Additional analyses suggested a reduced risk of cognitive impairment among the longer-term quitters. This study suggests a positive association between smoking during middle age and later risk of cognitive impairment.

Ten-year changes in the obesity, abdominal adiposity, and serum lipoprotein cholesterol measures of Western Samoan men.

Previously reported associations between abdominal adiposity and coronary heart disease (CHD) may be mediated through serum lipids. In the present longitudinal study, 43 Western Samoan men who participated in a 1982 study were recontacted for a second determination of anthropometric and serum lipoprotein cholesterol levels. The men showed dramatic increases in weight (mean change +/- SD: 10.5 +/- 8.8 kg), abdominal circumference (10.0 +/- 7.6 cm), total cholesterol (49.5 +/- 26.4 mg/dl), and non-HDL cholesterol (53.1 +/- 26.6 mg/dl). A new indicator was used to estimate changes in abdominal adiposity: the residual from the regression of change in the abdominal circumference on change in body weight (the AR). The AR was significantly correlated with changes in total (r = 0.38) and non-HDL cholesterol (r = 0.39). Changes in HDL cholesterol were correlated with changes in weight only (r = -0.37). These bivariate relations remained significant in multiple linear regression analyses. These longitudinal results are the first to suggest changes in abdominal adiposity are related to changes in total and non-HDL cholesterol levels.

Relations of body fat and fat distribution to the serum lipid, apolipoprotein and insulin concentrations of Samoan men and women.

OBJECTIVE: To examine relations between obesity and serum concentrations of lipoprotein cholesterol, apolipoproteins, triglycerides and insulin in American and Western Samoans. Associations are also described between these CHD risk factors and abdominal adiposity, and the potential mediating role of insulin in these relationships is examined. DESIGN: Cross-sectional, using a sub-sample from an observational epidemiological study of cardiovascular disease risk factors among Samoans. MEASUREMENT: Obesity is estimated by the body mass index (BMI), and fat distribution by the abdomen-hip circumference ratio (AHR). All biochemical parameters were measured in the fasted stated. SUBJECTS: The sub-sample is 178 men and 147 women who were free from hypertension, diabetes and heart disease. RESULTS: In multivariate linear regression analyses in men the BMI was positively associated with levels of total cholesterol, the total-HDL cholesterol ratio, apolipoprotein B, and the log of triglyceride and insulin concentrations, and negatively associated with HDL and HDL2 cholesterol. The quadratic term for BMI was also found to be significantly predictive of all metabolic parameters in men, except for the log of serum insulin concentrations. Among the women, in contrast, BMI levels were significantly associated only with concentrations of HDL2 cholesterol, triglyceride and insulin. In men, the associations between the AHR and the metabolic parameters were similar to those described for the BMI, but showed no indication of non-linearity. Addition of the log of insulin to these models had little effect on the relations between the AHR and the lipid parameters, with the exceptions of total cholesterol and triglycerides. As with BMI, the AHR was much les predictive of metabolic parameters in women than in men, with a significant relation existing only with the log of insulin concentrations. CONCLUSIONS: These cross sectional data indicate that overall and abdominal adiposity are important correlates of serum lipid parameters among Samoan men, though the associations with BMI are attenuated at higher levels. Neither anthropometric indicator has much relation with these CHD risk factors among the women, perhaps due to extremely high levels of obesity in this group.
