Harding S, Balarajan R. Longitudinal study of socio-economic differences in mortality among South Asian and West Indian migrants. Ethnicity & Health 2001; 6 (2): 121-128

Aim. To examine socio-economic differences in mortality of South Asian and West Indian migrants. Outcome measures. Relative risks of mortality, 1981-1997. Results, There was considerable upward social mobility but most people remained socially stable, mainly relatively disadvantaged compared to all other study members. High levels of owner occupied housing among South Asians at both censuses were an exception. Socio-economic differentials in mortality were significant with car access in 1981 (relative risk 1.32, 95% confidence interval 1.03-1.70), and housing (rented vs owner occupied relative risk 1.50, 95% confidence interval 1.08-2.08) among South Asians and among West Indians with car access in 1981 (relative risk 1.43, 95% confidence interval 1.05-1.94). Mortality was not significantly associated with socio-economic circumstances in 1971. Conclusion. The disparity between those who remained advantaged or who moved up, and those who remained persistently disadvantaged would have been a factor underlying the stronger differentials by later socio- economic circumstances. As these migrants age an increase in health inequalities could be expected.
