Aim : To investigate mortality of Caribbean migrants in England and Wales by duration of residence and age at migration. Method : Study members in a national cohort, aged 25-54 years in 1971, were followed up from 1971 to 2000. There were 1540 migrant Caribbeans amongst whom there were 329 deaths during follow-up. Cox regression models were used to analyse mortality from cardiovascular disease and cancers. All results were adjusted for sex and socioeconomic position. Results : All-cause mortality was not related to duration of residence or age at migration at ages 25-34 or 35-44 years in 1971. At ages 45-54 years a pattern of increasing mortality with each additional year of residence prior to 1971 (hazard ratio [HR]=1.07,95% CI : 0.95,1.20,144 deaths) and with each additional year of age at migration (HR=1.09,95% Cl : 0.97,1.22) was observed. Circulatory disease mortality, accounting for 40% of all deaths, contributed to this pattern. At ages 45-54 years, both duration of residence (HR=1.21,95% CI : 1.01,1.44,62) and age at migration (HR=1.25,95% CI : 1.06,1.49) increased per year of each. Of these deaths, stroke mortality was positively associated with both predictors (HR=1.38,95% CI : 1.10,1.74 for duration of residence and HR=1.44,95% CI : 1.15,1.80 for age at migration), a pattern due to effects at ages 45-54 years. Deaths from coronary heart disease showed similar trends in the oldest age cohort. No significant trends were observed for deaths from cancers. Conclusion : Circulatory disease mortality in Caribbean migrants increased with increasing duration of residence and age at migration in the oldest age cohort, primarily due to the effects from stroke mortality.
