Researchers at The University of Manchester’s Medical School, working with teams in India and Birmingham, have found that people moving from South Asia to the UK significantly increase their risk of contracting cardiovascular disease (CVD).
The British population has one of the highest rates of cardiovascular disease in the world, and people from the Indian subcontinent living in Britain are amongst the most susceptible to heart attacks and strokes. The research team from the University, Sandwell District General Hospital near Birmingham and the All India Institute of Medical Sciences in Delhi has therefore carried out a study, to measure directly the change in cardiovascular risk factors associated with migration to Britain.
In the three-year project, funded by the British Heart Foundation, the team studied 537 Gujaratis; comparing the lifestyles, eating and physical exercise patterns of those living in Sandwell with those remaining in their villages of origin in Gujarat.
“We found that people who had migrated to Sandwell were at considerably greater risk of CVD,” said Professor Kennedy Cruickshank. “On average people in Britain had much higher body mass, blood pressure, blood cholesterol and inflammation levels, because they consumed more calories in the form of fat and relatively less unrefined carbohydrates.
“Our findings suggest that time-pressured, urban lifestyles in the UK involve a greater fat and calorie intake than would be typical in Gujarat, due to the prevalence here of processed and convenience foods and red meat. In combination with Western lifestyle differences and labour-saving devices, the result is often obesity and associated health risks.
To our surprise, levels of physical activity did not actually differ between the sites, probably because nutritional intake in India was quite low. The greater dietary intake identified in the UK needs to be matched by more physical activity”.
Drs Jeetesh Patel & Elizabeth Hughes, who ran the work in Sandwell, added: “Diabetes and sugar intolerance were common in both India and Britain, but in Britain were more likely to occur in association with raised blood pressure and raised cholesterol.”
CVD has already been found to be the leading cause of mortality in people of Indian origin migrating to South Africa, Singapore, California and Canada. Even within India, the adoption of a more westernised lifestyle in the cities means that 8 -10% of the urban population succumb to the disease - compared with just 3 - 4% of rural people.
