Diabetes – US v UK.

Dr James Banks has found that the much higher rate of diabetes in US adults, compared to the UK,  is mainly due to a larger waist circumference for any given body mass index (BMI).

The team examined results from one study of 6,900 adults in England and a second study of 4,600 US adults of European descent.

Conventional risk factors for diabetes differed little between the two groups, yet rates of diabetes are nearly twice as high in the US.

While obesity was higher in US men (32% v 27% of English males), the BMI profile was very similar in women across the 2 nationalities, so BMI alone could not account for the difference.

When BMI was taken out of the equation by comparing people of the same BMI in both nationalities, it was found that the major risk factor was waist circumference, so larger US waists meant more US citizens at risk at each level.

The team used 3 sizes to grade as low risk (94 cm for men, 80 cm for women) medium risk, (up to 101 cm /88 cm respectively) and high risk (above these sizes).

Abdominal fat cells produce more triglycerides and proinflammatory markers than fat cells deposited elsewhere, contributing to higher insulin resistance and diabetes.

The researchers found waist circumference explained around three quarters of the country difference in diabetes rates for women and around 40% of the difference for men.

Even at the normal weight range, 41% of US women had a waist circumference in the high risk range, compared to 9% of English women.
