Nativity in the healthy migrant effect: Evidence from Australia

Area of Science:

• Public Health
• Epidemiology
• Sociology

Background:

• Migrant health is a critical public health concern.
• The 'healthy migrant effect' and its variations across different nativity groups remain poorly understood.
• Understanding these differences is crucial for targeted health interventions.

Purpose of the Study:

• To examine and compare the life expectancy (LE) and healthy life expectancy (HLE) of the Australian-born population with eight major migrant groups in Australia.
• To identify variations in migrant health status based on country of origin.
• To explore potential explanations for observed health outcome differences.

Main Methods:

• Analysis of Australian population data from 2006, 2011, and 2016.
• Comparison of LE and HLE between the Australian-born population and specific migrant groups.
• Calculation of the HLE/LE ratio to assess health-related quality of life.

Main Results:

• Overall, foreign-born populations exhibited higher LE and HLE but a lower HLE/LE ratio compared to the Australian-born population.
• Migrants from South Africa, Britain, and Germany showed similar or better LE, HLE, and HLE/LE ratios.
• Migrants from China, India, Italy, and Greece had higher LE but significantly lower HLE/LE ratios. Lebanese migrants experienced unchanging LE and declining HLE over the study period.

Conclusions:

• Significant variations in migrant health outcomes exist, strongly influenced by nativity.
• Sociocultural differences between origin and host countries, and migration selectivity, likely explain these health disparities.
• Targeted interventions are needed to improve the quality of life for migrants, especially those from diverse backgrounds or with challenging migration experiences.
