PEOPLE from most ethnic groups, who were born abroad but live in Scotland, have lower death rates than those born here, a study has found.

Chinese people have the lowest death rates, followed by people from Indian, Pakistani and Bangladeshi ethnic groups.

Both males and females in most ethnic minority groups had lower death rates than the White Scottish population.

It also found white Scottish people born abroad have lower death rates than those born in Scotland.

Researchers led by the University of Edinburgh looked at records of 4.26 million people who died in Scotland between 2001 and 2013, noting the ethnic group and country of birth in each case.

These records were securely linked to anonymised data from the 2001 Scotland census.

Death rates for Chinese males of all ages, for example, were almost half those of the White Scottish population.

People who identify as Other British or Other White also had a survival advantage, the study found.

White Irish men had similar death rates, while males of Mixed Background had slightly higher death rates.

The effects were similar even when the researchers took into account socio-economic status.

Researchers say differences in health-related behaviours could be a key reason for the trend.

The findings are part of the Scottish Health and Ethnicity Linkage Study, which aims to improve the future health status of all populations in Scotland.

Lead researcher, Professor Raj Bhopal, of the University of Edinburgh's Usher Institute of Population Health Sciences and Informatics, said: "Many people are surprised to learn that ethnic minority populations, and particularly those born abroad, have lower mortality than the Scottish population.

"The findings contradict the widely held perception that immigrants and ethnic minorities are a burden on the health and health care of our society.

"In fact, we have a great deal to learn in Scotland about how to improve the health of the whole population, particularly the White Scottish people."
