The association between birthplace in different regions of the world and cardiovascular mortality among residents of Spain.

The objective of this study is to estimate the association of birthplace with mortality from cardiovascular diseases in residents of Spain by analysing immigrant populations that are unlikely to have adopted health-related attitudes and behaviours of the host country. Data from the population register and cause of death register were used for the period 2001-2005. The study included people aged 20-64 years. Age-adjusted mortality from cardiovascular diseases--and from ischaemic heart disease, cerebrovascular disease and hypertension-related disease--according to birthplace were estimated and compared with those for the native Spanish population by mortality rate ratios. Compared with the native Spanish population, residents who came from Eastern Europe, Sub-Saharan Africa and South Asia had a higher risk of mortality from most of the cardiovascular diseases analysed. Women from North Africa and the Caribbean also had a higher risk of cardiovascular mortality. A higher risk of mortality from ischemic heart disease was observed in persons from the Middle East, and from cerebrovascular disease in those from Eastern Asia. Compared with the native Spanish population, residents from South America and Eastern Asia had a lower risk of mortality from ischemic heart disease. This pattern of mortality from cardiovascular diseases in residents of Spain who have come from different regions of the world is very similar to the findings of studies in other countries, and probably reflects the burden of disease in the countries of origin.
