Mortality in Micronesian Nauruans and Melanesian and Indian Fijians is not associated with obesity.

The association of obesity with mortality was investigated in population-based samples of Micronesian Nauruans (n = 1,400), Melanesian Fijians (n = 1,279), and Indian Fijians (n = 1,182), over 10 years from 1982 in Nauru, and 11 years from 1980 in Fiji. At the end of follow-up, vital status was known for all Nauruans and all but 3.5% of Fijians. Mortality rates were higher in Nauru than Fiji, and in Melanesians than Indians. The mean body mass index of decedents was similar to or less than (Nauruan men, p < 0.001) that of survivors in each sex-ethnic group. Crude mortality rates showed an inverse relation with body mass index in Nauruan men, with inconsistent relations in other sex-ethnic groups. After stratification by diabetes status, there was no relation between mortality and obesity in nondiabetic subjects, but an inverse relation was observed among diabetic subjects in each population. These findings persisted even after the exclusion of subjects who died within the first 2 years of follow-up. After controlling for age, smoking, and diabetes status in Cox proportional hazard models, body mass index (as a continuous variable) was not related to mortality in any sex/ethnic group and tended to be negatively associated with mortality risk. Interactions of body mass index with age, smoking, and diabetes status were not significant. Mortality risk was significantly increased in older subjects and in diabetic subjects, and cigarette smoking also increased risk in some groups. Stratification of analyses according to cigarette smoking did not alter the nature of the results. The association of mortality and body mass index categorized by quartiles was also investigated. After adjusting for age alone, or age, smoking, and diabetes status, the lower quartiles of body mass index were consistently associated with the highest relative risk for mortality. Quadratic terms for body mass index did not improve Cox models in subjects with normal glucose tolerance. Relations with cardiovascular disease mortality were also assessed and results were inconsistent, although positive trends were observed in Nauruan women (p = 0.02) and Melanesian men (p = 0.06). Overall, there was little evidence to suggest that obesity was a risk factor for total or cardiovascular mortality in these populations. However, obesity is clearly associated with a high risk of diabetes and other morbid conditions and at least on this basis it would seem desirable to prevent obesity in these and other Pacific populations.

Labour circulation and the village economy in Fiji.

The author examines circular labor migration in Fiji. "This paper is organized into five sections. The first section provides a brief discussion of two major perspectives of labour circulation in developing countries. The second section presents the state of the Fijian village in the context of the current pattern of uneven development in Fiji. The practice of labour circulation by Fijian villagers is dealt with in the third section. In the last two sections, issues concerning the maintenance of the polarized pattern and the preservation of the village mode of production are discussed."

The prevalence of sexually transmitted disease agents in pregnant women in Suva.

Routine testing of 440 women (257 Fijians, 183 Indians) at the first antenatal attendance identified Chlamydia trachomatis in 50% of Fijians and 38% of Indians; the seropositivity rates for syphilis were 14.2% and 1.7% respectively, and the isolation rates for N. gonorrhoeae were 3.1% in Fijians and 1.1% in Indians.

Venereal diseases in the islands of the North Pacific.

Apart from the Japanese islands, and those of Karabati (lately Gilbert Islands), which lie just north of the equator, the islands of the northern Pacific Ocean are either American owned or otherwise administered. Even the Japanese islands were controlled by the USA for varying numbers of years after the second world war. Venereal disease statistics from Guam, the Trust Territory of the Pacific Islands, and the Gilbert Islands have been collated by the South Pacific Commission and will be presented in a second paper. Those from the Hawaiian Islands (the fiftieth state of the USA) are published by the United States Public Health Service and include those from Honolulu, the capital. While the rates per 100 000 for both syphilis and gonorrhoea are lower than those for the USA as a whole, the trends since 1970 have been less satisfactory in the state of Hawaii than for the whole of the United States. While the disturbing increasing incidence of primary and secondary syphilis was checked in 1977, that of gonorrhoea has continued to rise. The number of cases of gonorrhoea also increased in Guam and the Trust Territory of the Pacific Islands but there has been a recent fall from earlier peak figures. The pattern of venereal disease in the most developed Pacific islands is thus gradually approaching what may be expected elsewhere in modern western society and it would seem logical to expect that this trend will continue.

Venereal diseases in the islands of the South Pacific.

The island territories of the South Pacific vary considerably in area and in size of population; Pitcairn has a population of 100 in two square miles whereas Papua New Guinea has a population of 2,990,000 in approximately 175,000 square miles. Today the whole ocean is traversed by air routes. Recently, the prevalence of gonorrhoea has decreased in the northern region but increased in the eastern and western; in all these regions the reported prevalence exceeds 200 cases per 100,00 population. In an area where yaws was once widespread, syphilis is being increasingly recognised. Although the figures for syphilis are clearly higher because of the greater use of serological screening, many of the reported cases are of early infection. Yaws has been eliminated from most of the South Pacific Islands but is still present in the western region--more than 99% of the reported cases occurring in Papua New Guinea, particularly in the offshore islands.

The use of scientific models in the study of Polynesian migration.

"This paper has attempted to show that...currently popular explanatory models of Polynesian migration contain logical and empirical weaknesses." The work of John Connell and of I. G. Bertram and R. F. Watters is examined. The author concludes that although neither approach is shown to be without merit, this review "has served to show where further analysis, interpretation, and empirical research are required in order to develop more accurate, complete, and useful theories."

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.

Movement in the French Pacific: recent situation and prospects.

"Population movements in the French Pacific territories (French Polynesia, New Caledonia, Wallis and Futuna) are discussed. The local government of French Polynesia and the French authorities have tried since the beginning of the 1980s to prevent migration to Tahiti by retaining the population on the outer islands and by encouraging return migration.... The purpose of this paper is not to describe in detail the population movements in the French territories, but to review recent changes in the course of these movements, examine the impact of policy measures, and discuss the prospects for the next ten or twenty years."

Australia and Pacific Islander migration.

"The net migration gains of Pacific Islands-born to Australia increased steeply from 1986, mostly due to migration from Fiji in 1987-1988 after the coups. This is reflected in the differing migration trends and characteristics of the Fiji-born compared to other Islander migrants. Australia also receives secondary migrants from New Zealand, facilitated by the free movement of residents allowed by the Trans-Tasman Agreement. Due to poor job opportunities in the Islands and economic restructuring in the countries of the Pacific rim, Island states seem to have adopted a policy of increased brain drain to ensure remittances flows. This could also be related to changing fertility rates in the Islands in the 1980s."

Sexually-transmitted disease risk in a Micronesian atoll population.

The potential health threat of AIDS to the native island-based populations in the Pacific is now widely appreciated by those working in the public-health sector throughout the region. Although several countries in the region are yet to identify any cases of AIDS or HIV seropositivity, there is reason to suspect that heterosexual contact may emerge as a predominant mode of spread of HIV infection into native Pacific island populations. Sexual networks and their relationship to potentially 'risky behaviours' are described for a single native Micronesian atoll community on the basis of ethnographic observation and interviewing. This description is combined with the investigation of historic-demographic dimensions of the epidemiology of sexually-transmitted diseases in the same population to draw some conclusions about the opportunities for HIV transmission and acquisition among the sexually-active portions of this community. Although sexually-transmitted diseases have not had an appreciable epidemiological or demographic impact on the population in the past, the sexual networks within the community and beyond provide ample opportunity for the introduction and spread of sexually transmitted diseases, including HIV and its sequel AIDS.
