Mortality in Pacific island countries around 1980: geopolitical, socioeconomic, demographic and health service factors.

Inhabitants of Pacific island countries experience a wide range of levels and cause structures of mortality. Data on socioeconomic, geopolitical and demographic variables have been analysed here to identify correlates and determinants of mortality in Pacific island countries circa 1980. The mortality data used in the study were the best available for the period and are reasonably accurate; descriptive data were derived from recognised sources. Political status was a major correlate, with independence positively associated with mortality. However, the influence of political status was partly accounted for by economic and social variables. Economic indices, particularly imports per capita, were major inverse correlates of mortality. Disparities in life expectancy occurred between malarious and nonmalarious countries, and these were not explicable by other factors. Melanesians, especially women, experienced high mortality rates. Education and doctor availability were both associated with increased life expectancy. Intercorrelation and confounding need to be taken into account in the interpretation of this analysis. The results have ramifications for policy development in the Pacific island countries themselves, and for investment and aid programs from major donor nations and organisations.
