Infant mortality and ethnicity in an indigenous European population: novel evidence from the Finnish population register

All-cause mortality among three generations of Moluccans in the Netherlands

BACKGROUND

Mortality variations have been reported for ethnic minority groups compared with their host populations. It is uncertain how this mortality variations change over time as younger generations become older and mix with the host population. This study aimed to examine all-cause mortality among three generations of Moluccans in the Netherlands, and to compare Moluccans with a mixed and non-mixed ethnic background.

METHODS

We used data from the death and municipality registry for the years 2000 through 2013, including all registered Dutch inhabitants. A list of Moluccan surnames was used to select the Moluccan population. Mortality differences were calculated by Poisson regression, controlling for sex, age and district socio-economic status.

RESULTS

High all-cause mortality rates were observed in all generations of Moluccans although the extent of the differences between Moluccans and the Dutch were smaller in second (1.15, 1.07-1.23) and third generation (1.14, 1.00-1.29) compared with the first generation (1.55, 1.49-1.60). Higher all-cause mortality is also reflected in the higher mortality from most causes of death except neoplasms and external causes. Both mixed and non-mixed Moluccans showed high all-cause mortality among the first (child) and second generation compared with the Dutch.

CONCLUSION

Our findings show a higher all-cause mortality in three generations of Moluccans compared with the Dutch. The results show that mortality inequalities may persist, though in an attenuated form, over generations among ethnic minorities.
