AIMS/HYPOTHESIS: The A (minor) allele of CREBRF rs373863828 has been associated with increased BMI and reduced risk of type 2 diabetes in the Samoan populations of Samoa and American Samoa. Our aim was to test rs373863828 for associations with BMI and the odds of type 2 diabetes, gout and chronic kidney disease (CKD) in Māori and Pacific (Polynesian) people living in Aotearoa/New Zealand. METHODS: Linear and logistic regression models were used to analyse the association of the A allele of CREBRF rs373863828 with BMI, log-transformed BMI, waist circumference, type 2 diabetes, gout and CKD in 2286 adults...

OBJECTIVES: Obesity leads to deleterious effects on not only cardiovascular health but also on the reproductive health of women. We estimate the prevalence of menstrual irregularity and of polycystic ovarian syndrome (PCOS) in Samoan women, among whom obesity prevalence is extremely high. We explore the association of these reproductive health conditions with adiposity, cardiometabolic risk factors, and androgen levels. METHODS: A cross-sectional sample of Samoan women 25-39 years of age (n = 470) from a larger population-based genome-wide association study of adiposity and cardiometabolic disease was assessed for the prevalence of oligomenorrhea/amenorrhea (OM/AM) using a self-reported questionnaire...

Cancer cell cytotoxicity was used to guide the isolation of nine new swinholide-related compounds, named samholides A-I (1-9), from an American Samoan marine cyanobacterium cf. Phormidium sp. Their structures were determined by extensive analysis of 1D and 2D NMR spectroscopic data. The new compounds share an unusual 20-demethyl 44-membered lactone ring composed of two monomers, and they demonstrate structural diversity arising from geometric isomerization of double bonds, sugar units with unique glyceryl moieties and varied methylation patterns...

OBJECTIVE: Among young Samoan children, diet may not be optimal: in 2015, 16·1 % of 24-59-month-olds were overweight/obese, 20·3 % stunted and 34·1 % anaemic. The present study aimed to identify dietary patterns among 24-59-month-old Samoan children and evaluate their association with: (i) child, maternal and household characteristics; and (ii) nutritional status indicators (stunting, overweight/obesity, anaemia). DESIGN: A community-based, cross-sectional study...

OBJECTIVES: Pacific Islander Americans are a small, but quickly growing population that experiences alarming disparities in obesity and obesity-related chronic illnesses influenced by dietary patterns. This population also has a unique culinary heritage including traditional foods and more contemporary imports such as tinned meats and refined carbohydrates. This analysis is a novel attempt to understand the sociodemographic factors influencing island foods consumption. DESIGN: A sample of 240 Samoan and Tongan adults in California from the Pacific Islander Health Study was used...

The influenza pandemic of 1889 was the first truly global flu outbreak in scope. Characterised by high morbidity and low mortality, it spread rapidly across Europe and the rest of the world along trading routes. It reached mainland Britain in December 1889. The responses of medical practitioners in Britain and the British colonies to the pandemic were heavily featured in the British Medical Journal and reveal a confusing picture around causality, contagion and infection. Cases from the colonies (Cape Town, India, Australia, Samoan Islands, Hong Kong) as presented in the journal are explored in an attempt to reconstruct the mainstream medical belief of the time...

OBJECTIVE: Investigating a large and ethnically diverse cohort from the Pacific region, we aimed to replicate and extend the recently reported findings that a CREBRF genetic variant is strongly associated with body mass index in Samoans. METHODS: A birth cohort of more than six thousand children was utilised. In this study, genotyping of two markers (rs12513649 and rs373863828) was undertaken in Māori, Pacific, European and Asian individuals in the cohort. RESULTS: We report that these CREBRF genetic variants are not confined to Samoans but are prevalent in all other Pacific populations sampled, including Māori...

Research identifying racial and ethnic disparities in child protective services (CPS) involvement in the U.S. has focused on the overrepresentation of Black children and the growing Latino child population. Little attention has been paid to children of Asian origin, the most underrepresented group of children in the U.S. CPS system. The objective of this analysis was to examine subgroup patterns of CPS involvement in California for Asian and Pacific Islander (API) children prospectively based on maternal nativity and ethnic origin...

Introduction: Samoa, like other Pacific Island countries, faces a persistent challenge to reduce smoking use with relatively limited resources. As a signatory to the WHO FCTC, Samoa is obligated to introduce measures to reduce tobacco use and is currently trialling a text message smoking cessation programme (mCessation) to achieve this outcome. Cigarettes remain relatively cheap and are widely available, but little is known about how smoking is initiated or why and how people quit smoking in the Samoa...

BACKGROUND: American Samoan women are particularly at risk of obesity-related non-communicable disease (NCD), requiring efficacious interventions to protect their health and that of their infants. Prior studies have identified pregnancy as an ideal time for behavior change interventions related to NCD. AIM: This study aimed to understand American Samoan women's conceptions of health during pregnancy, their motivations for pregnancy behavior change, and the role of their family in both enabling and preventing these changes...

Several sponges from American Samoa, collected by the Coral Reef Research Foundation, Republic of Palau, were tentatively identified by one of us as Acanthotetilla cf seychellensis (Thomas 1973), due to the possession of relatively small acanthose oxeas, compared to those of other species of the genus Acanthotetilla Burton 1959. These sponges were later compared to Cinachyrella australiensis (Carter 1886), taking into account the lack of conspicuous spination on the acanthose oxeas and general features of spiculation and skeletal organisation...

BACKGROUND: The island country of Samoa (population 188,000 in 2011) forms part of Polynesia in the South Pacific. Over the past several decades Samoa has experienced exceptional modernization and globalization of many sectors of society, with noncommunicable diseases (NCD) now the leading cause of morbidity and mortality. The evolution of risk factor prevalence underpinning the increase in NCDs, however, has not been well described, including tobacco smoking which is related to cardiovascular disease, lung cancer, and chronic obstructive pulmonary disease...

This study examines aspects of neighbourhood social environments (namely, neighbourhood safety, cohesion and connection) and child-specific built environment attributes in relation to children's independent mobility. The results suggest that children aged 8-13 years with parents who perceive their neighbourhood as more cohesive and more connected, and are located closer to school, engaged in higher levels of independently mobile trips. The qualitative component of this research revealed that for NZ European, Māori, Samoan and other Pacific parents, 'people danger' was the most common concern for letting their children go out alone, whereas for Asian and Indian parents, 'traffic danger' was the most common reason for their concern...

Though disparities in birth weight by race/ethnicity have been extensively reported in the United States, few studies have systematically investigated factors attributing to its variability. For 10,638,415 singleton infants born during 2009-2012 in the United States, we examined birth weight differences among 14 races and ethnicities (non-Hispanic white, non-Hispanic Black, American Indian, Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, Hawaiian, Guamanian, Mexican, Puerto Rican and Cuban), after sequentially adjusting for maternal, socio-economic and behavioral factors...

It has been suggested that a 'thrifty' genotype hypothesis can account for high prevalence of obesity in the island populations of Oceania. A recent genome-wide association study revealed that a missense variant, rs373863828-A (p.Arg457Gln), of the CREBRF gene (encoding CREB3 regulatory factor) was associated with an excessive increase in body mass index (BMI) in Samoans. In the present study, the association of rs373863828-A with an increase in BMI was examined in four Austronesian (AN)-speaking populations in Oceania...
