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.
