The consequences in terms of lost life years on women with diabetes are greater than for men according to the team’s model, though more work, they say, is required to understand why.
The study is published in Cardiovascular Endocrinology and Metabolism.
Dr Adrian Heald is from The University of Manchester and a Consultant in Diabetes and Endocrinology at Salford Royal.
He said: “This study highlights the importance of early effective engagement and long-term management in patients with Diabetes.
“And it’s especially important as numbers of people diagnosed with diabetes are on the rise and in light of the link between diabetes and COVID-19 deaths.
He added: “We hope our linking of poor glycaemic control to expected mortality in such a quantitative way will be helpful to both clinicians and people with diabetes
“Knowing the risks of poor control of their blood sugars will bring home its importance of and will support them in their efforts to achieve their targets.”
The team acknowledge the paper has used national level mortality data rather than GP practice level data.
And the impact of other factors such as smoking, inactivity, overweight, hypertension and taking of statins will be the subject of future study
However they still argue is likely the blood sugar level will remain a strong independent determinant of mortality.
