Hepatitis B Prevalence and Risk Factors in Foreign-Born Asians and Pacific Islanders at a Federally Qualified Health Center in Hawai'i, 2015-2020.

The objective of this study was to estimate the prevalence of chronic hepatitis B infection in foreign-born Asians and Pacific Islanders at Kalihi-Palama Health Center in Honolulu, Hawai'i, and to assess the association between both chronic and resolved hepatitis B infection and risk factors such as household exposure to hepatitis B virus and geographic location of birthplace. The study involved cross-sectional data from 997 participants who accessed medical services at Kalihi-Palama Health Center between September 2015 and July 2020. The prevalence of chronic hepatitis B was 10.7%. On multivariable logistic regression analysis, the adjusted prevalence odds ratio of chronic hepatitis B infection was 3.3 times greater (95% confidence interval: 1.1, 9.2) for those who reported household contact with a person with hepatitis B infection than those who reported no such contact. No association was found with place of birth in this study population. Age was a significant predictor of chronic hepatitis B, with participants between 35-44 years of age having the highest prevalence. Age was also a significant predictor of resolved hepatitis B infection, with participants 65 years of age or older having the highest prevalence. These findings emphasize the need for targeted screening and appropriate follow-up-including vaccination or treatment-in this at-risk population.

The prevalence of soil transmitted helminth infections in minority indigenous populations of South-East Asia and the Western Pacific Region: A systematic review and meta-analysis.

INTRODUCTION: Soil transmitted helminth (STH) infections cause one of the most prevalent diseases in man. STHs disproportionately impact socio-economically disadvantaged communities including minority indigenous populations. This systematic review aimed to quantify the prevalence of STH infection within minority indigenous populations of the South-East Asia and Western Pacific Regions. METHODS: The systematic review was conducted in accordance with The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines following a published protocol. A random effects meta-analysis was used to estimate the pooled prevalence of STH infection, and meta-regression analysis was used to quantify associations with study characteristics. Where comparative data were available, sub-group analysis was conducted to evaluate the risk of STH infection in minority indigenous people relative to other population groups. The heterogeneity between studies was evaluated visually using Forest plots and was assessed quantitatively by the index of heterogeneity (I2) and Cochran Q-statistics. RESULTS: From 1,366 unique studies that were identified, 81 were included in the final analysis. The pooled prevalence of infection within minority indigenous populations was 61.4% (95% CI 50.8, 71.4) for overall STH infection; 32.3% (95% CI 25.7, 39.3) for Ascaris.lumbricoides; 43.6% (95% CI 32.6, 54.8) for Trichuris.trichiura; 19.9% (95% CI 15.7, 24.5) for hookworm and 6.3% (95% CI 3.2, 10.2) for Strongyloides.stercoralis. A significant increase in T. trichiura prevalence was observed over time. The stratified analysis showed that the prevalence of infection for STH overall and for each STH species were not significantly different in minority indigenous participants compared to other populations groups. CONCLUSION: The prevalence of STH infection is high within minority indigenous populations across countries at very different levels of socio-economic development. The increasing prevalence of T. trichiura calls for the implementation of more effective therapies and control strategies.

Multiethnic genome-wide association study of differentiated thyroid cancer in the EPITHYR consortium.

Incidence of differentiated thyroid carcinoma (DTC) varies considerably between ethnic groups, with particularly high incidence rates in Pacific Islanders. DTC is one of the cancers with the highest familial risk suggesting a major role of genetic risk factors, but only few susceptibility loci were identified so far. In order to assess the contribution of known DTC susceptibility loci and to identify new ones, we conducted a multiethnic genome-wide association study (GWAS) in individuals of European ancestry and of Oceanian ancestry from Pacific Islands. Our study included 1554 cases/1973 controls of European ancestry and 301 cases/348 controls of Oceanian ancestry from seven population-based case-control studies participating to the EPITHYR consortium. All participants were genotyped using the OncoArray-500K Beadchip (Illumina). We confirmed the association with the known DTC susceptibility loci at 2q35, 8p12, 9q22.33 and 14q13.3 in the European ancestry population and suggested two novel signals at 1p31.3 and 16q23.2, which were associated with thyroid-stimulating hormone levels in previous GWAS. We additionally replicated an association with 5p15.33 reported previously in Chinese and European populations. Except at 1p31.3, all associations were in the same direction in the population of Oceanian ancestry. We also observed that the frequencies of risk alleles at 2q35, 5p15.33 and 16q23.2 were significantly higher in Oceanians than in Europeans. However, additional GWAS and epidemiological studies in Oceanian populations are needed to fully understand the highest incidence observed in these populations.

The epidemiology of patients undergoing meningioma resection in Auckland, New Zealand, 2002 to 2011.

The incidence of meningioma is known to vary by gender and ethnicity. This study aimed to describe the epidemiological characteristics of a 10-year cohort of patients undergoing meningioma resection at Auckland City Hospital, Auckland, New Zealand. Of particular interest was whether there was any difference in meningioma incidence and recurrence rates between New Zealand Maori and Pacific Island patients compared with other ethnic groups. The study was a retrospective analysis of 493 patients with pathologically confirmed meningioma over the period 1 January 2002 to 31 December 2011. Based on this neurosurgical cohort, the minimum incidence of meningioma in the Auckland region was 3.39 per 100,000 population per year (95% C.I. 3.02-3.80) for the study period. Meningioma was significantly more common in women than men by a ratio of 4.2:1. New Zealand Maori and Pacific Island patients had a significantly higher incidence of meningioma than other ethnic groups. New Zealand Maori had a meningioma incidence 2.74 times that of Europeans (95% C.I. 2.01-3.73, p < 0.001). Pacific Island patients had 2.03 times higher incidence of meningioma than Europeans (95% C.I. 1.42 - 2.89, p < 0.001). The overall meningioma recurrence rate was 21.6% with a mean follow-up of 77 months. Recurrence rates for meningioma among Pacific Island patients were significantly higher than for other ethnic groups (hazard ratio 1.73, p = 0.008). Multivariate analysis of clinical variables confirmed the significance of traditional prognostic factors such as WHO tumour grade and Simpson grade of surgical excision in predicting meningioma recurrence.

Predictors of mortality in Maori, Pacific Island, and European patients diagnosed with dementia at a New Zealand Memory Service.

BACKGROUND: As the economic impact of dementia on health and social care increases, governments require disease-specific epidemiological data that will help inform spending and policy decisions. The aim of this study is to examine predictors of mortality in dementia in consecutive referrals to a New Zealand (NZ) memory service that includes Maori, Pacific Islander, and NZ European patients. METHODS: Date of birth, sex, ethnicity, living situation, cognitive function, dementia subtype, dementia severity, physical comorbidity, and medication data were collected from electronic health records. The resulting data set was linked to administrative data on mortality and last hospital contact dates to allow time-dependent survival analyses. RESULTS: The risk of death in people with dementia was increased by age (adjusted HR per year 1.08, 95%CI:1.05-1.12) and lower cognitive score at baseline (adjusted HR for severe impairment:2.54, 95% CI:1.25-5.16), and was reduced by cholinesterase inhibitors (adjusted HR:0.54, 95% CI:0.34-0.88). Compared to NZ Europeans (HR:1.19, 95% CI:0.63-2.25), antipsychotics increased the risk of death three-fold in Maori (adjusted HR:3.62, 95% CI:0.79-16.7) and Pacific Islanders (adjusted HR:2.54, 95%CI:1.10-5.85). CONCLUSIONS: Further research is required to elucidate the mechanisms underlying the survival rates in Maori and Pacific Islanders living with dementia in NZ,and their increased risk of death if antipsychotics are used.

Coastal proximity of populations in 22 Pacific Island Countries and Territories.

The coastal zones of Small Island States are hotspots of human habitation and economic endeavour. In the Pacific region, as elsewhere, there are large gaps in understandings of the exposure and vulnerability of people in coastal zones. The 22 Pacific Countries and Territories (PICTs) are poorly represented in global analyses of vulnerability to seaward risks. We combine several data sources to estimate populations to zones 1, 5 and 10 km from the coastline in each of the PICTs. Regional patterns in the proximity of Pacific people to the coast are dominated by Papua New Guinea. Overall, ca. half the population of the Pacific resides within 10 km of the coast but this jumps to 97% when Papua New Guinea is excluded. A quarter of Pacific people live within 1 km of the coast, but without PNG this increases to slightly more than half. Excluding PNG, 90% of Pacific Islanders live within 5 km of the coast. All of the population in the coral atoll nations of Tokelau and Tuvalu live within a km of the ocean. Results using two global datasets, the SEDAC-CIESIN Gridded Population of the World v4 (GPWv4) and the Oak Ridge National Laboratory Landscan differed: Landscan under-dispersed population, overestimating numbers in urban centres and underestimating population in rural areas and GPWv4 over-dispersed the population. In addition to errors introduced by the allocation models of the two methods, errors were introduced as artefacts of allocating households to 1 km x 1 km grid cell data (30 arc-seconds) to polygons. The limited utility of LandScan and GPWv4 in advancing this analysis may be overcome with more spatially resolved census data and the inclusion of elevation above sea level as an important dimension of vulnerability.

The Importance of Pedestrian Network Connectivity for Adolescent Health: A Cross-sectional Examination of Associations between Neighbourhood Built Environments and Metabolic Health in the Pacific Islands Families Birth Cohort Study.

The research aim was to investigate associations between objectively-assessed built environment attributes and metabolic risk in adolescents of Pacific Islands ethnicity, and to consider the possible mediating effect of physical activity and sedentary time. Youth (n = 204) undertook a suite of physical assessments including body composition, blood sampling, and blood pressure measurements, and seven day accelerometry. Objective measures of the neighbourhood built environment were generated around individual addresses. Logistic regression and linear modelling were used to assess associations between environment measures and metabolic health, accounting for physical activity behaviours. Higher pedestrian connectivity was associated with an increase in the chance of having any International Diabetes Federation metabolic risk factors for males only. Pedestrian connectivity was related to fat free mass in males in unadjusted analyses only. This study provides evidence for the importance of pedestrian network connectivity for health in adolescent males. Future research is required to expand the limited evidence in neighbourhood environments and adolescent metabolic health.

Ranked Importance of Childhood Obesity Determinants: Parents' Views across Ethnicities in New Zealand.

Maori, Pacific, Indian, and New Zealand European pre-school children's caregivers' views on determinants of childhood obesity are needed to inform strategies that will reduce disparities in prevalence. Nineteen focus groups were conducted to explore the relative influence of factors contributing to body weight in children. Predetermined and participant-suggested factors were ranked. Discussion data were inductively analysed. The cost of healthy foods was the highest ranked factor across all groups. Ranked similarly were ease of access to takeaways and lack of time for food preparation. Cultural factors followed by screen time induced sedentariness in children and lack of time to ensure children exercised was next. Participant-raised factors included lack of familial, social, and health promotion support, and others' behaviour and attitudes negatively impacting what children ate. All groups rejected stereotyping that blamed culture for higher obesity rates. Compared to the Maori and NZ European groups, the Pacific Island and Indian participants spoke of losing culture, missing extended family support, and not having access to culturally appropriate nutrition education or social support and services. Public health policies need to mitigate the negative effects of economic deprivation on food insecurity. Complementary interventions that increase access to healthier meal choices more often are needed.

Study of HLA genes in Russia Bering Island Aleuts.

HLA-A, -B, -C and -DRB1 alleles and haplotypes have been studied in a group of Aleuts from Bering Island (Commander Islands, Russia). Many of their ancestors were original from other Aleutian Islands, like Attu and Atka Islands (USA) and may have had a low degree of admixture with Russians. HLA haplotypes are found to be specific and quite different from other First North America Inhabitants (including Amerindians, Na-Dene and Eskimo), as it was previously shown in a less numerous Aleut population. HLA-A*24:02 is found in a very high frequency; this character is shared by Pacific and Amerindian populations. In conclusion, HLA, other genetic markers, anthropological and linguistic traits make Aleuts to be different from First America Inhabitants and closer to Europeans and Asians: specifically Aleut relatedness has been found with Scandinavian Saami (Lapps) and Finns and Baikal Lake area Buryats, where all of them may have initialing being originated.

Energy drink consumption in a pluri-ethnic population of adolescents in the Pacific.

OBJECTIVE: Energy drinks are very popular among teenagers but may cause health problems. Energy drink consumption is partly associated with energy drink perception, but little is known about this in the Pacific Island Countries and Territories. The aim of this cross-sectional study was to identify the relationships between energy drink consumption, energy drink perception, weight status and sociodemographic characteristics in a school-going sample of Pacific adolescents. DESIGN: A cross-sectional study carried out in the schools during school hours between July 2015 and April 2016. SETTING: Sociodemographic characteristics, weight status, energy drink perception, and quantity of energy drinks consumed were obtained. Chi-square tests of independence, independent t tests, multivariate logistic regressions and multiple linear regressions were used. SUBJECTS: A representative sample of 678 New Caledonian adolescents (11-16 years). RESULTS: We found that one third of New Caledonian adolescents consume energy drinks. Boys are more likely to drink them than girls and Polynesians drink significantly more than European and Melanesian adolescents. Higher energy drink consumption in the New Caledonian adolescents is associated with good or neutral perceptions of the energy drink impact on health. Moreover, sex (being male) significantly influences the total energy drink consumption per week. Energy drink consumers have a tendency toward better perceptions of energy drinks than non-consumers. CONCLUSIONS: Nutritional education targeting energy drink consumers should take these results into account by providing (community-based) educational programs, especially for adolescents from low socioeconomic backgrounds, boys, or those living in rural areas.

Mental illness stigma among Pacific Islanders.

Native Hawaiians and other Pacific Islanders (NHPI) rarely seek mental health treatment for reasons that are minimally understood. To assess the mental illness stigma context in NHPI communities that may be contributing to low help-seeking, this study collected novel stigma data from two large U.S. NHPI communities from October 2017 to January 2018, then compared this data to national stigma data from the U.S. public. Survey data were collected from 222 community-dwelling NHPI participants recruited by research-trained NHPI staff. Surveys incorporated well-established vignettes describing persons with major depression and schizophrenia. Study data were compared to U.S. general public data from the 2006 General Social Survey: the largest U.S. stigma study. Compared to the U.S. public, NHPI participants reported greater stigma toward mental illness in ways likely to impede help-seeking including: (1) more frequently endorsing stigmatizing causal attributions of depression and schizophrenia, (2) less frequently perceiving disorders as serious, and (3) more commonly desiring social distance from persons with depression. Study data are the first to reveal the presence of a strongly stigmatizing context in NHPI communities likely to hinder NHPI help-seeking. Thus, culturally tailoring anti-stigma interventions to appropriately target NHPI mental health attitudes and beliefs may prove effective in promoting NHPI help-seeking.

Prevalence of strongyloidiasis and schistosomiasis among migrants: a systematic review and meta-analysis.

BACKGROUND: Global migration from regions where strongyloidiasis and schistosomiasis are endemic to non-endemic countries has increased the potential individual and public health effect of these parasitic diseases. We aimed to estimate the prevalence of these infections among migrants to establish which groups are at highest risk and who could benefit from screening. METHODS: We did a systematic review and meta-analysis of strongyloidiasis and schistosomiasis prevalence among migrants born in endemic countries. Original studies that included data for the prevalence of Strongyloides or Schistosoma antibodies in serum or the prevalence of larvae or eggs in stool or urine samples among migrants originating from countries endemic for these parasites and arriving or living in host countries with low endemicity-specifically the USA, Canada, Australia, New Zealand, Israel, and 23 western European countries-were eligible for inclusion. Pooled estimates of the prevalence of strongyloidiasis and schistosomiasis by stool or urine microscopy for larvae or eggs or serum antibodies were calculated with a random-effects model. Heterogeneity was explored by stratification by age, region of origin, migrant class, period of study, and type of serological antigen used. FINDINGS: 88 studies were included. Pooled strongyloidiasis seroprevalence was 12·2% (95% CI 9·0-15·9%; I2 96%) and stool-based prevalence was 1·8% (1·2-2·6%; 98%). Migrants from east Asia and the Pacific (17·3% [95% CI 4·1-37·0]), sub-Saharan Africa (14·6% [7·1-24·2]), and Latin America and the Caribbean (11·4% [7·8-15·7]) had the highest seroprevalence. Pooled schistosomiasis seroprevalence was 18·4% (95% CI 13·1-24·5; I2 97%) and stool-based prevalence was 0·9% (0·2-1·9; 99%). Sub-Saharan African migrants had the highest seroprevalence (24·1·% [95% CI 16·4-32·7]). INTERPRETATION: Strongyloidiasis affects migrants from all global regions, whereas schistosomiasis is focused in specific regions and most common among sub-Saharan African migrants. Serological prevalence estimates were several times higher than stool estimates for both parasites. These data can be used to inform screening decisions for migrants and support the use of serological screening, which is more sensitive and easier than stool testing. FUNDING: None.

Incidence, Clinical Manifestations, and Severity of Juvenile Idiopathic Arthritis Among Maori and Pacific Island Children.

OBJECTIVE: To describe the incidence, demographics, diagnostic clinical manifestations, and severity of juvenile idiopathic arthritis (JIA) in Maori and Pacific Island children compared to European children. METHODS: A chart review was conducted of all children with JIA seen by Auckland pediatric and rheumatology services between the years 2000 and 2015. Demographic data and diagnostic clinical manifestations, including poor prognostic features, were collated. The incidence, diagnostic, clinical manifestations, and severity of JIA were determined and compared between ethnic groups, in particular Maori, Pacific Island, and European children. RESULTS: The overall incidence in a New Zealand cohort of children with JIA was 5.1/100,000 children per year, which was significantly higher among European children (7.2/100,000 children per year) compared to all other ethnic groups. Poor prognostic features at diagnosis were present in 36% of children with JIA, with significantly more Maori and Pacific Island children presenting with poor prognostic features compared to European children (58% versus 27%; P = 0.0001). Maori and Pacific Island children had significantly more poor prognostic features per child associated with JIA (1.10 versus 0.37; P < 0.0001) and in oligoarticular and polyarticular JIA (1.28 versus 0.40; P < 0.0001), which was independent of socioeconomic status. Significant features included cervical involvement (25% versus 9%; P = 0.03), erosive changes (22% versus 8%; P = 0.05), joint space narrowing (13% versus 2%; P = 0.02), and positive rheumatoid factor polyarticular disease (47% versus 14%; P = 0.01). CONCLUSION: Maori and Pacific Island children were more likely to present with poor prognostic features at diagnosis, although the incidence of JIA was demonstrated to be significantly higher among European children compared to all ethnic groups.

Greater insulin response to acute fructose ingestion among Maori and Pacific people compared to European people living in Aotearoa New Zealand.

BACKGROUND: Fructose consumption has been linked with insulin resistance, obesity and diabetes, which are more prevalent in those of Maori or Pacific ethnicity compared to New Zealand European. AIM: To determine whether the acute effects of fructose consumption on serum glucose, insulin, lipids and C-reactive protein differs according to body mass index (BMI) and/or ethnicity. METHODS: Participants of Maori (n = 25), Pacific (n = 26) or New Zealand European (n = 25) ethnicity consumed a 64 g fructose/16 g glucose solution. Changes in lipids, glucose, insulin and C-reactive protein were analysed using mixed models for repeated measures. RESULTS: After adjustment for age and gender, those with higher BMI had a higher glucose (P = 0.0064) and insulin (P = 0.0007) response than those with lower BMI. Those of Maori or Pacific ethnicity had similar glucose levels (P = 0.077) to those of New Zealand European ethnicity but higher insulin responses (P = 0.0005), which remained after additional adjustment for BMI (P = 0.001). Reported sugar-sweetened beverages (SSB) intake was higher among Maori and Pacific than New Zealand European (median 1.0 vs 0.0 SSB/day P = 0.002). CONCLUSION: Even after adjustment for BMI, those of Maori and Pacific ethnicity have a significantly higher insulin response to fructose than New Zealand Europeans. Higher habitual SSB intake may be a contributing factor.

Physical Activity Among Native Hawaiians and Pacific Islanders: A Systematic Review and Meta-Analysis.

OBJECTIVE: To examine the proportion of Native Hawaiian and Pacific Islander (NHPI) meeting recommended physical activity guidelines for Americans (PAG) and determine differences in physical activity (PA) by sex and between NHPI and Asians when data are disaggregated. DESIGN: Systematic review and meta-analysis. SETTING: Articles identified in CINAHL, The Cochrane Library, Embase, PsychINFO, PubMed, Scopus, SocINDEX, SPORTDiscus, and Web of Science. PARTICIPANTS: NHPI children and adults, and Asian adults. INTERVENTIONS: Proportion of NHPI meeting PAG and differences in PA involvement by sex and by ethnicity. METHODS: Summary reporting for articles, and meta-analysis using random-effects and inverse-various weighted models. CONCLUSIONS AND IMPLICATIONS: Just over one-third of NHPI children met the PAG (mean = 38.6%, 95% CI [32.43-45.08]), with more males (42.8%) than females (34.7%) meeting the guidelines (t = 6.74, df = 1, P = .02). Less than half met the PAG for combination (mean = 48.7%, 95% CI [34.69-62.97]), moderate (mean = 47.1%, 95% CI [33.62-61.07]), and about one-third met the PAG for vigorous PA (mean = 33.4%, 95% CI [24.55-43.62]). There were no significant differences between Asians and NHPI in PA. Policy, systems, and environmental changes as well as culturally appropriate interventions are needed to increase physical activity among NHPI.

Pre-participation cardiovascular evaluation in Pacific Island athletes.

BACKGROUND: Pre-participation cardiovascular evaluation (PPE) aims to detect cardiac disease with sudden cardiac death (SCD) risk. No study has focused on Pacific Island athletes. METHODS: A total of 2281 Pacific Island athletes were studied with (i) a questionnaire on family, personal history and symptoms, (ii) a physical examination and (iii) a 12-lead ECG. RESULTS: 85% presented a normal history and examination. A positive family history was 1.4-1.9 fold higher in Melanesians, Polynesians and Métis than in Caucasians, while a positive personal history, abnormal symptoms and abnormal examination was 1.3 fold higher in Melanesians and Métis than in others. Neither gender nor training level had a bearing on these results. Melanesians had higher T wave inversions (TWIs) in V2-V4 leads but had no CV abnormalities. Lateral or infero-lateral TWIs were found in 6 male and in 5 highly trained athletes and cardiomyopathies were diagnosed in 3/6 athletes. Overall, 3.9% athletes were found to have a CV abnormality and 0.8% had a risk of SCD. Polynesians and males were more at risk than the others while the level of training made no difference. In athletes at risk of SCD, the main detected CV diseases were cardiomyopathies, Wolff-Parkinson-White (WPW) and severe valve lesions of rheumatoid origin. CONCLUSIONS: PPE revealed that 3.9% presented CV abnormalities. A risk of SCD was found in 0.8% with cardiomyopathies, WPW, and severe valve lesions of rheumatoid origin. Melanesians, Polynesians and male of high level of training were more at risk than others.

Decolonizing Community Psychology by Supporting Indigenous Knowledge, Projects, and Students: Lessons from Aotearoa New Zealand and Canada.

Community psychology has long stood as a social justice agitator that encouraged reformation both within and outside of the academy, while keeping a firm goal of building greater well-being for people in communities. However, community psychology's historically Euro-centric orientation and applied, interventionist focus may inadvertently promote colonial agendas. In this paper, we focus on the example of Indigenous Pacific peoples, drawing upon experience working among Indigenous iTaukei Fijian communities and with Indigenous frameworks for promoting student success in Aotearoa New Zealand and Canada. We outline how community psychology curricula can strive toward decolonization by (a) teaching students to respectfully navigate complexities of Indigenous knowledge and traditions that contest colonial ways of being and doing, (b) act as facilitators who build toward collaborative community projects and model this research practice to students, and (c) boost Indigenous student success by fostering relationships with instructors and fellow students that are embedded within the relational model of self that is often absent in individualistic-oriented Western academic settings.

Neighborhood social cohesion and sleep outcomes in the Native Hawaiian and Pacific Islander National Health Interview Survey.

Study Objective: Native Hawaiians and Pacific Islanders (NHPIs) have the lowest attainment of healthy sleep duration among all racial and ethnic groups in the United States. We examined associations of neighborhood social cohesion with sleep duration and quality. Methods: Cross-sectional analysis of 2464 adults in the NHPI National Health Interview Survey (2014). Neighborhood social cohesion was categorized as a continuous and categorical variable into low (<12), medium (12-14), and high (>15) according to tertiles of the distribution of responses. We used multinomial logistic regression to examine the adjusted odds ratio of short and long sleep duration relative to intermediate sleep duration. We used binary logistic regression for dichotomous sleep quality outcomes. Sleep outcomes were modeled as categorical variables. Results: Forty percent of the cohort reported short (<7 hours) sleep duration and only 4% reported long (>9 hours) duration. Mean (SE, range) social cohesion score was 12.4 units (0.11, 4-16) and 23% reported low social cohesion. In multivariable models, each 1 SD decrease in neighborhood social cohesion score was associated with higher odds of short sleep duration (odds ratio [OR]: 1.14, 95% confidence interval [CI]: 1.02, 1.29). Additionally, low social cohesion was associated with increased odds of short sleep duration (OR: 1.53, 95% CI: 1.10, 2.13). No associations between neighborhood social cohesion and having trouble falling or staying asleep and feeling well rested were found. Conclusion: Low neighborhood social cohesion is associated with short sleep duration in NHPIs.

Higher Heart Weight in New Zealand Maori and Pacific Islanders.

Heart weight is dependent on sex, age, height, and weight. Although previous autopsy studies showed no differences in heart weight between different ethnic groups, none have examined the New Zealand population of Maori and Pacific Islanders (Polynesians). The presented study compared heart weights between 101 European and 85 Polynesian suicide hanging deaths from New Zealand. Univariate linear regression coefficients for age, male sex, height, body weight, body mass index, and Polynesian ethnicity were positive and significant (P < 0.05). Apart from body mass index, subsequent multivariate analysis showed that all regression coefficients remained positive and significant (P < 0.05). Polynesian ethnicity seemed to be an independent predictor for increased heart weight in the study population. Apart from possible genetic factors, the higher heart weight in Polynesians may have other underlying reasons. Caution is required when interpreting heart weight in cases of sudden natural deaths, especially in this population.
