Reduce diabetes risk with healthier lifestyle

Keeping fitA new study we part-funded has shown that South Asian or African Caribbean women can reduce their risk of developing diabetes by keeping the weight off.

Researchers from Imperial College London have been following a group of people from South East England for several years in a project called the SABRE study. The study is looking for clues about why some people are more likely to develop health problems.

In particular, the research team is aiming to work out why people from South Asian or African Caribbean backgrounds are more likely to develop diabetes. We know that people from these groups are at greater risk of diabetes, and therefore more likely to go on to develop heart disease.

The researchers found that in South Asian and Afrcian Caribbean women, the increased diabetes risk is down to higher body fat levels, in particular around the waist, and resistance to insulin. In men, the picture is more complicated, but lifestyle is an important factor.

Eating well and getting active can have a significant protective effect on your health

Our Research Advisor, Dr Hélène Wilson, said: “This study suggests the higher rate of diabetes – a major risk factor for heart attacks and strokes – in some South Asian and African Caribbean women is due to increased levels of obesity, particularly the build-up of fat around the waist, and higher resistance to insulin, which helps the body process sugar.

“This is a very encouraging discovery because it underlines the fact that controlling your weight by eating well and getting active can have a significant protective effect on your health. There's a wealth of existing evidence that keeping the weight off by eating a healthy balanced diet and being physically active will reduce your risk of heart disease and type 2 diabetes, whatever your ethnic group."

The findings - the first to be announced by the SABRE team - were published in journal Diabetes Care. In the coming months the team will announce more discoveries.
