The future of Western Samoan migration to New Zealand.

"The history of Samoan migration to New Zealand, a demographic profile of the migrants, and the future of such migration are discussed. Migration became a serious phenomenon after independence in 1962, with primarily young, unskilled workers moving to take up jobs in the agricultural and service sectors. Remaining essentially unchanged since 1962, New Zealand's immigration policy gives preferential treatment to Western Samoans and recognizes their valuable labor contribution. The future of migration to New Zealand is discussed in the context of the costs and benefits to Western Samoa.... The author argues that emigration has been beneficial rather than deleterious to Western Samoa's development...." Data are from official sources.

Soaring and non-soaring bats of the family pteropodidae (flying foxes, Pteropus spp.): wing morphology and flight performance.

On oceanic islands, some large diurnal megachiropteran bat species (flying foxes; Pteropus spp.) frequently use thermal or slope soaring during foraging flights to save energy. We compared the flight morphology and gliding/soaring performance of soaring versus non-soaring Pteropus species, one pair on American Samoa and one pair on the Comoro Islands, and two other soaring/flap-gliding species and one non-soaring species. We predicted that the soaring species should have a lower body mass, longer wings and, hence, lower wing loadings than those species that use mainly flapping flight. This would give a lower sinking speed during gliding, a higher glide ratio, and enable the bats to make tighter turns with lower sinking speeds than in the non-soaring species. We theoretically calculated the gliding and circling performances of both the soaring and non-soaring species. Our results show that there are tendencies towards longer wings and lower wing loadings in relation to body size in the gliding/soaring flying foxes than in the non-soaring ones. In the species-pair comparison of the soaring and non-soaring species on American Samoa and the Comoro Islands, the soarers on both islands turn out to have lower wing loadings than their non-soaring partners in spite of opposite size differences among the pairs. These characteristics are in accordance with our hypothesis on morphological adaptations. Most differences are, however, only significant at a level of P<0.1, which may be due to the small sample size, but overlap also occurs. Therefore, we must conclude that wing morphology does not seem to be a limiting factor preventing the non-soarers from soaring. Instead, diurnality in the soaring species seems to be the ultimate determinant of soaring behaviour. The morphological differences cause visible differences in soaring and gliding performance. The glider/soarers turn out to have lower minimum sinking speeds, lower best glide speeds and smaller turning radii than the non-soarers. When the wing measurements and soaring performance are normalized to a body mass of 0.5 kg for all species, the minimum sinking speed becomes significantly lower (P<0.05) in the three soaring and the one flap-gliding species (0.63 m s(-)(1)) than in the three non-soaring species (0.69 m s(-)(1)). Interestingly, the zones in the diagrams for the glide polars and circling envelopes of these similar-sized bats become displaced for the glider/soarers versus the non-soarers. The glide polars overlap slightly only at the gliding speeds appropriate for these bats, whereas the circling envelopes do not overlap at the appropriate bank angles and turning radii. This points towards adaptations for better gliding/soaring performance in the soaring and gliding species.

Prevalence and predictors of smoking behavior among Samoans in three geographical regions.

OBJECTIVES: Provide comprehensive data on smoking behavior among Samoans. DESIGN: Cross-sectional, using systematic random sampling procedures, and in-person interviews. SETTING: US Territory of American Samoa, Hawaii, and Los Angeles, California. PARTICIPANTS: 1834 adult, non-institutionalized Samoans. INTERVENTION: None. MAIN OUTCOME MEASURES: Prevalence and independent predictors of smoking. RESULTS: Approximately one fourth (26.6%) of Samoans were current smokers, with 31.4% of men and 22.5% of women currently smoking. More current smokers were found in American Samoa (28.9%), followed by Hawaii (26.9%) and Los Angeles (24.1%, P<.001). At each site, Samoan men compared with the women were significantly more likely to smoke (P<.001), initiate smoking earlier (P<.05), and smoke more cigarettes (P<.05). Cessation rates for the sample were very low. Predictors of smoking included being younger, male, married, less educated, with lower income, and more acculturated. CONCLUSION: The high smoking and low cessation rates indicate that smoking-related diseases will be significant causes of morbidity and mortality for Samoans for many years. The findings further underscore the importance of documenting smoking patterns and their determinants for subgroups rather than aggregates such as Asian American and Pacific Islanders. If Samoans are to meet the Healthy People 2010 tobacco goals, there is a need to: 1) develop tailored tobacco awareness and cessation programs based on the recommendations made by the Taskforce on Community Preventive Services; 2) understand the complex interactions between social, cultural, and psychological determinants of smoking and cessation behaviors; and 3) develop policies to limit availability of tobacco, environmental exposure from tobacco, and increase cessation efforts.

Culture change and stress in Western Samoan youth: Methodological issues in the cross-cultural study of stress and immune function.

This study was designed to pursue three objectives: 1) investigate the impact of culture change on children and adolescents in Western Samoa; 2) introduce a cross-cultural perspective to studies of psychosocial stress and immune function; and 3) evaluate the utility of minimally invasive methods for assessing immune function. Seven hundred sixty individuals between the ages of 4 and 20 years were recruited from three distinct geographic regions within Western Samoa that differ in degree of westernization. Finger prick samples of whole blood were collected from each individual and analyzed for antibodies against the Epstein-Barr virus (EBV; an indirect marker of cell-mediated immune function) and C-reactive protein (a nonspecific marker of current infection). After controlling for age, sex, and current infection, EBV antibody levels were significantly elevated in urban Apia and rural Upolu, indicating lower levels of cell-mediated immune function. The results suggest a higher degree of psychosocial stress in these regions, possibly due to exposure to westernizing influences. Am. J. Hum. Biol. 12:792-802, 2000. Copyright 2000 Wiley-Liss, Inc.

Sequence diversity of South Pacific isolates of Taro bacilliform virus and the development of a PCR-based diagnostic test.

We have analysed the sequence variability in the putative reverse transcriptase (RT)/ribonuclease H (RNaseH) and the C-terminal coat protein (CP)-coding regions from Taro bacilliform virus (TaBV) isolates collected throughout the Pacific Islands. When the RT/RNaseH-coding region of 22 TaBV isolates from Fiji, French Polynesia, New Caledonia, Papua New Guinea (PNG), Samoa, Solomon Islands and Vanuatu was examined, maximum variability at the nucleotide and amino acid level was 22.9% and 13.6%, respectively. Within the CP-coding region of 13 TaBV isolates from Fiji, New Caledonia, PNG, Samoa and the Solomon Islands, maximum variability at the nucleotide and amino acid level was 30.7% and 19.5%, respectively. Phylogenetic analysis showed that TaBV isolates from the Solomon Islands showed greatest variability while those from New Caledonia and PNG showed least variability. Based on the sequences of the TaBV RT/RNaseH-coding region, we have developed a PCR-based diagnostic test that specifically detects all known TaBV isolates. Preliminary indexing has revealed that TaBV is widespread throughout Pacific Island countries. A sequence showing approximately 50% nucleotide identity to TaBV in the RT/RNaseH-coding region was also detected in all taro samples tested. The possibility that this may represent either an integrated sequence or the genome of an additional badnavirus infecting taro is discussed.

Eosinophilic meningitis beyond the Pacific Basin: the global dispersal of a peridomestic zoonosis caused by Angiostrongylus cantonensis, the nematode lungworm of rats.

The principal etiologic agent of human eosinophilic meningitis, Angiostrongylus cantonensis, was first detected in rats in Canton, China in 1933. The first human case was detected on Taiwan in 1944. Epidemic outbreaks were noted on Ponape (E. Caroline Is.) from 1944 to 1948. The disease may present as transient meningitis or a more severe disease involving the brain, spinal cord and nerve roots, with a characteristic eosinophilia of the peripheral blood and CSF. Since 1961 it has been known that human infections are usually acquired by purposeful or accidental ingestion of infective larvae in terrestrial mollusks, planaria and fresh-water crustacea. There is no effective specific treatment. The African land snail, Achatina fulica played an important role in the panpacific dispersal of the organism: it will be important in Africa in the future as well. Rats were, and will continue to be the principal agents of expansion of the parasite beyond the Indopacific area. During and just after WWII the parasite was introduced, and/or spread passively from South and Southeast Asia into the Western Pacific islands and eastward and southward through Micronesia, Melanesia, Australia and into Polynesia, sequestered in shipments of war material and facilitated by post-war commerce. In the 1950s numerous cases were identified for the first time on Sumatra, the Philippines, Taiwan, Saipan, New Caledonia, and as far east as Rarotonga and Tahiti. Then cases were detected in Vietnam, Thailand, Cambodia, Java, Sarawak, the New Hebrides, Guam and Hawaii during the 1960s. Subsequently in the Pacific Basin the disease has appeared on Okinawa, other Ryukyu islands, Honshu, Kyushu, New Britain, American Samoa and Western Samoa, Australia, Hong Kong, Bombay, India, Fiji and most recently in mainland China. The parasite in rats now occurs throughout the Indopacific Basin and littoral. Beyond the Indopacific region, the worm has been found in rodents in Madagascar (ca 1963), Cuba (1973), Egypt (1977), Puerto Rico (1984), New Orleans, Louisiana (1985) and Port Harcourt, Nigeria (1989). Human infections have now been detected in Cuba (1973), Réunion Island (1974) and Côte d'Ivoire (1979) and should be anticipated wherever infected rats of mollusks have been introduced. Caged primates became infected in zoos in Hong Kong (1978) and New Orleans and Nassau, Bahamas (1987). The use of mollusks and crustacea as famine foods, favored delicacies and medicines has resulted in numerous outbreaks and isolated infections. Economic and political instability, illicit trade, unsanitary peridomestic conditions and lack of health education promote the local occurrence and insidious global expansion of parasitic eosinophilic meningitis.(ABSTRACT TRUNCATED AT 400 WORDS)

Pacific Island suicide in comparative perspective.

All available data for thirteen Pacific Island nations are used in a comparative analysis of suicide levels and characteristics. Age, sex and method of suicide are examined in detail. Global comparison shows Pacific rates are amongst the highest reported. Female youth rates exceed male rates in Western Samoa and amongst Fiji Indians. Method of suicide (paraquat ingestion) is instrumental in determining high rates in Western Samoa, especially in females. The broad causal theme is societal transition. Commonality and diversity are discussed.

Is leptin sensitivity the link between smoking cessation and weight gain?

The known association between smoking cessation and weight gain, and the suggested role of leptin in the control of body weight, led to the present study which examined the association between smoking and serum leptin concentrations. Mean serum leptin levels, independent of body mass index (BMI), were calculated in male smokers and non-smokers from Nauru, Western Samoa and Mauritius. Smokers were generally leaner than non-smokers, and of similar ages. Levels of physical activity and glucose tolerance status were similar for smokers and non-smokers in Nauru and Western Samoa, while in Mauritius smokers were more active and less likely to be diabetic. Leptin concentrations in smokers were significantly lower than in non-smokers, even after adjusting for BMI, waist/hip ratio (WHR) or waist girth (P < or = 0.04). This association was independent of diabetes status. Smoking, via nicotinic mechanisms, may modify the sensitivity of hypothalamic leptin receptors and consequently modulate leptin synthesis and reduce body weight.

Biogeography of Tongan birds before and after human impact.

Bones deposited in caves show that, before the arrival of humans, at least 27 species of land birds lived on the Tongan island of 'Eua, where 13 indigenous species live today. Six of these 13 species were recorded from pre-human strata; three others probably occurred on 'Eua in pre-human times but were not in the fossil sample; and four others probably colonized 'Eua since the arrival of humans approximately 3000 years ago. Of the 23 species of extinct or extirpated land birds recorded from 'Eua, the nearest geographic occurrences of conspecifics or most closely related congeners are from the Solomon Islands (1 species), New Caledonia (2 species), Fiji and/or Samoa (9 species), elsewhere in Tonga (8 species), or unknown (3 species). The avifauna of West Polynesia (Fiji-Tonga-Samoa) is more closely related to that of Melanesia than that of East Polynesia. There was little pre-human turnover in Tongan land birds. The arrival of humans has influenced the Tongan avifauna more than any climatic, tectonic, or biological event of the past approximately 100,000 years.

Molecular epidemiology of dengue in the Pacific: introduction of two distinct strains of dengue virus type-1 [corrected] into Hawaii.

In 2000, a major dengue epidemic, caused by the type-1 virus (DENV-1), began in the Pacific and Asia, with cases still being reported in 2006. The phylogenetic analysis of full-length sequences of the envelope-protein gene of DENV-1 isolates recovered during outbreaks in Hawaii and Tahiti in 2001-2002 indicated that most Hawaiian isolates were Tahitian in origin. All the Hawaiian and Tahitian isolates were identified as the Pacific subtype (i.e. subtype IV) of DENV-1. A Hawaiian isolate, collected from a resident who had travelled to Samoa, differed significantly at the nucleotide level, however, from all the other Hawaiian strains, clustering, in the phylogenetic analysis, with a virus previously isolated from another visitor to Samoa. These results not only indicate that two distinct strains of DENV-1 were introduced into Hawaii in 2001 but also illustrate the ease with which dengue can be carried across distances of many thousands of miles.

Autosomal STR variation in five Austronesian populations.

Human population characteristics at the genetic level are integral to both forensic biology and population genetics. This study evaluates biparental microsatellite markers in five Austronesian-speaking groups to characterize their intra- and interpopulation differences. Genetic diversity was analyzed using 15 short tandem repeat (STR) loci from 338 unrelated individuals from 5 Pacific islands populations, including the aboriginal Ami and Atayal groups from Taiwan, Bali and Java in Indonesia, and the Polynesian islands of Samoa. Allele frequencies from the STR profiles were determined and compared to other geographically targeted worldwide populations procured from recent literature. Hierarchical AMOVA analysis revealed a large number of loci that exhibit significant correspondence to linguistic partitioning among groups of populations. A pronounced divide exists between Samoa and the East (Formosa) and Southeast Asian (Bali and Java) islands. This is clearly illustrated in the topology of the neighbor-joining tree. Phylogenetic analyses also indicate clear distinctions between the Ami and Atayal and between Java and Bali, which belie the respective geographic proximities of the populations in each set. This differentiation is supported by the higher interpopulation variance components of the Austronesian populations compared to other Asian non-Austronesian groups. Our phylogenetic data indicate that, despite their linguistic commonalities, these five groups are genetically distinct. This degree of genetic differentiation justifies the creation of population-specific databases for human identification.

Non-multiresistant and multiresistant methicillin-resistant Staphylococcus aureus in community-acquired infections.

OBJECTIVE: To survey Staphylococcus aureus strains isolated from patients presenting from the community, comparing clinical features and antibiotic sensitivity profiles between multiresistant and non-multiresistant methicillin-resistant and methicillin-sensitive isolates. DESIGN: Retrospective case series. PARTICIPANTS AND SETTING: Patients who presented to emergency or dermatology departments in hospitals served by the South Western Sydney Area Health Service between 1 May 1998 and 30 April 1999. All patients with methicillin-resistant S. aureus (MRSA) and the first 100 with methicillin-sensitive S. aureus were eligible. MAIN OUTCOME MEASURES: Patient demographic characteristics; risk factors; clinical presentation; treatment; outcome; and isolate antibiotic susceptibility. RESULTS: 139 patients were eligible, and 122 had clinical records available. Ten of these 122 (8%) had multiresistant MRSA, 26 (21%) non-multiresistant MRSA and 86 (70%) methicillin-sensitive S. aureus. Among patients with non-multiresistant MRSA, 29% (7/24) were born in New Zealand, Samoa or Tonga, a higher proportion than among those with multiresistant MRSA or methicillin-sensitive S. aureus (P= 0.03). Nearly half (44%) of non-multiresistant MRSA strains were community-acquired in patients with no risk factors. Two-thirds of patients with non-multiresistant MRSA (17/26) presented with cellulitis or abscess, and 58% (11/19 evaluable patients) required surgical treatment. CONCLUSIONS: Non-multiresistant MRSA strains are common, especially among people born in New Zealand, Samoa or Tonga, and are usually community acquired. Medical practitioners should routinely swab all staphylococcal lesions for culture and sensitivity.
