Trends in amenable mortality in New Zealand 1968-1987

Area of Science:

• Public Health
• Health Services Research
• Epidemiology

Background:

• Amenable mortality rates reflect healthcare system effectiveness.
• Significant health disparities persist between Maori and non-Maori populations in New Zealand.
• Understanding trends in amenable mortality is crucial for health equity.

Purpose of the Study:

• To analyze and compare trends in amenable mortality rates between Maori and non-Maori New Zealanders.
• To estimate the contribution of medical services to observed mortality declines.
• To identify disparities in the impact of medical services between Maori and non-Maori individuals.

Main Methods:

• Analysis of amenable mortality rates using regression models.
• Comparison of trends between Maori and non-Maori populations.
• Estimation of medical services' contribution to mortality decline.

Main Results:

• Mortality from causes amenable to medical intervention declined faster than non-amenable mortality for both groups.
• The proportion of mortality decline attributed to improved medical services was greater for non-Maori, particularly females.
• Maori consistently had higher mortality ratios for amenable causes compared to non-amenable causes, indicating systematic healthcare impact differences.

Conclusions:

• Despite overall declines, Maori experienced a persistent excess of amenable mortality over 20 years.
• Disparities in the impact of medical services contribute to poorer health outcomes for Maori.
• Findings underscore the need for targeted interventions to improve medical service provision for Maori people.
