Ethnic minorities most affected by long-term pollution in the UK

A new study by researchers at the University of St Andrews suggests that ethnic minorities and non-UK-born individuals are more affected by higher exposure to air pollution than the rest of the UK population.

Exposure to air pollution has been shown to be a major reason behind poor health outcomes, mostly related to cardiovascular and respiratory systems. Ethnic inequalities in health and environmental exposures have also been shown to exist in society.

The research, led by Mary Abed Al Ahad, from the University’s School of Geography and Sustainable Development, investigated the association between long-term exposure to air pollution and poor self-reported health in the UK. It sought to find out if people from different ethnic backgrounds and those born outside the UK are more affected by air pollution than the rest.

The research used data from the Understanding Society: The UK Household Longitudinal Study, which asked around 68,000 adults about their health over a period of 11 years. Researchers also used detailed information about air pollution in the areas where the participants lived.

The results showed that higher levels of certain air pollutants were linked to worse health overall. This was mostly because of where people lived, not because of changes in pollution over time.

The study also found that people from Indian, Pakistani/Bangladeshi, and Black/African/Caribbean backgrounds tended to report worse health if they were exposed to higher levels of air pollution compared to white British people. People born outside the UK also had worse health when they were exposed to more air pollution compared to those who were born in the UK.

The findings follow from research conducted by Ms Abed Al Ahad last year on the link between living in more polluted areas and mental well-being.
