Do migrants' remittances decline over time? Evidence from Tongans and Western Samoans in Australia.

"There is concern that Pacific Island economies dependent on remittances of migrants will endure foreign exchange shortages and falling living standards as remittance levels fall because of lower migration rates and the belief that migrants' willingness to remit declines over time. The empirical validity of the remittance-decay hypothesis has never been tested. From survey data on Tongan and Western Samoan migrants in Sydney [Australia], this paper estimates remittance functions using multivariate regression analysis. It is found that the remittance-decay hypothesis has no empirical validity, and migrants are motivated by factors other than altruistic family support, including asset accumulation and investment back home."

Mortality in Niue, 1978-82.

This report is an analysis of mortality in the population of Niue Island over the years 1978-82. The overall level of mortality in Niue is low. Life expectancy at birth is correspondingly high (66.5 years). Because of the extensive migration of Niueans during the period of study the death rate may be underestimated and the life expectancy correspondingly overestimated. Infant mortality has dropped from over 200 deaths per 1000 live births during the 1940s to around 10 per 1000 during the period under study. The major causes of premature mortality in Niuean males were injury/poisoning followed by cardiovascular disease. In females infection, injury/poisoning and neoplasia were the major causes of mortality. The 1980 epidemic of dengue fever had an appreciable effect on mortality in this small population. Except for dengue fever, the pattern of mortality in Niue is similar to that in many developed countries. Preventive efforts against metabolic and cardiovascular disease (including hypertension and diabetes) should continue in order to control mortality from these causes, Mosquito programmes, and emergency measures if epidemics threaten, are required so that deaths from haemorrhagic dengue are prevented.

Dengue type 1 epidemic with haemorrhagic manifestations in Fiji, 1989-90.

A dengue type 1 epidemic occurred in Fiji between July 1989 and July 1990. Virus isolation in C6/36 cell cultures and Toxorhynchites mosquitos yielded 36 strains. Of the 3686 cases recorded by the Ministry of Health, 60% involved indigenous Fijians and 37%, Indians. A house-to-house survey revealed that a large majority of patients had classical dengue symptoms and 8% reported haemorrhagic manifestations. Among the children and adults hospitalized for dengue, 43% had haemorrhagic manifestations, including epistaxis, gingival bleeding, haematemesis, melaena and haematuria. A total of 15 patients with haemorrhagic manifestations and/or shock died, 10 of whom were aged 0-15 years; the diagnoses were confirmed in four cases by virus isolation or serology.

Popular participation in community health programmes.

Community health programmes can be one of the most important and most available forms of education for the total community. This article outlines health programmes and health education initiatives, as well as approaches to participatory training, in several South Pacific countries.

Racial and familial factors in otitis media. A point prevalence study on Easter Island.

Of the 249 children aged 5 to 9 years who live on Easter Island, 220 underwent complete otolaryngological evaluation. Twenty children were found to have otitis media (acute, chronic, or both). Three of these children were genetically impure natives, nine were of mixed parentage, and eight were "continentals" (with a birth origin other than the island). None of the genetically pure natives had otitis media. Our data show that, in a population with all factors in common except for familial and racial background, the point prevalence of otitis media is higher in children of mixed or continental origin than in genetically pure native children. The high prevalence of otitis media in children of mixed parentage and in one particular family of European ancestry suggests the presence of intrinsic or pronicity factors that are seemingly transmissible.

Occurrence and prevention of rheumatic fever among ethnic groups of Hawaii.

To assess the occurrence of acute rheumatic fever (RF) among the ethnic groups of Hawaii, the case records of hospitalized children with RF in Oahu were reviewed for the period from October 1976 to September 1980. One hundred four of the records met the modified Jones criteria. Incidence rates per 100,000 children were as follows: Japanese, 0; white, 9; Filipino, 9.1; Hawaiian and part-Hawaiian, 27.2; and Samoan, 96.5. Carditis was most common among Samoan children; it occurred in nine of 18 children. A streptococcal, throat culture program for children with respiratory infections was in progress in 60% of Oahu's public schools during this period of time. Children with positive cultures were excluded from school until the start of treatment. However, RF occurred with equal frequency in participating and nonparticipating schools. Rheumatic fever continues to be a substantial problem among Polynesian children in Hawaii, and it is apparent that the school-based primary prevention program used in Hawaii to control streptococcal disease has not altered the frequency of RF among them.

X-linked dominant chondrodysplasia punctata: a peroxisomal disorder?

X-linked dominant chondrodysplasia punctata is characterised by resolving irregular punctate calcifications of epiphyses, variable ichthyosis and atrophoderma, short stature, and cataracts. We report on a patient with this syndrome who had transiently abnormal peroxisomal function tests. We review the literature and propose that X-linked dominant chondrodysplasia punctata is a peroxisomal disorder and that its phenotype can be explained by X chromosome lyonisation and the relative proliferation of cells expressing the normal X allele.

Bergmann's rule and the thrifty genotype.

One of Roberts' key contributions was his work demonstrating the applicability of several ecological rules to human populations (Roberts [1953] Am. J. Phys. Anthropol. 11:533-558; [1978] Climate and Human Variability, 2nd ed., Menlo Park, CA: Cummings). His finding that average body weight systematically covaries with mean annual temperature was widely taken as confirmation of Bergmann's rule for humans. More recently his findings on weight and temperature have been extended and confirmed (Ruff [1994] Yrbk. Phys. Anthropol. 37:65-407; Katzmarzyk and Leonard [1995] Hum Biol Council Program Abstracts 132) although the strength of the association may be decreasing when considering more recent surveys (Katzmarzyk and Leonard [1995]). Roberts noted in 1953 that Oceanic populations may be somewhat of an exception to Bergmann's rule, and we propose that Neel's ([1962] Am. J. Hum. Genet. 14:353-362) thrifty genotype model may account for some of the deviation from predicted weights among these populations. We provide an updated version of the thrifty genotype model, suggesting that selection for energetic efficiency may have occurred for some Oceanic populations during the voyaging to and settlement of their island homes. Under conditions of modernization the thrifty genotype may be manifesting as high rates of obesity and NIDDM among Polynesians and Micronesians. First, using measurements of adult male weight from 19 Oceanic populations, we demonstrate the extreme nature of their deviation from predicted weight based on Roberts' regression of weight on mean annual temperature. Next, we regress the deviations from predicted weight on NIDDM prevalence for these 19 populations, producing a highly significant regression (R2 = 0.46; P < 0.001), consistent with expectations if the thrifty genotype is responsible for the high weights.
