Diabetes patients who are overweight, but not obese can expect to outlive slimmer persons with similar diseaseCristina Cantor (Author) Published Date : May 05, 2015 23:47 IST
People suffering from type-2 diabetes with excess weight but not reckoned as obese can expect to outlive other diabetic individuals with normal weight according a report published by scientists on Monday in yet another example of obesity paradox . Even as dire warnings are issued by public health officials on the consequences of being overweight and employers pressurize workers to slim down through wellness programs , the paradox between longevity and weight continues. Studies reveal that while obesity contributes to an increase in risk of developing CVC or cardiovascular disease, CVD patients with excess weight live longer compared to patients with normal weight.
Similarly while it is known that the chances of getting type-2 diabetes increases with obesity, it is unclear whether overweight has a survival advantage for diabetics.
Conflicting answers have emerged from sixteen studies in the past. Some studies observed that overweight diabetics presented a lower mortality rate while other studies did not. But, many of these studies were beset with problems of methodology that included short follow up, few patients, or use of questionnaires as opposed to clinical records.
The new study led by Dr. Pierluigi Cstanzo and Stephen Atkin of Unversitiy of Hull, Britain was an effort to do better. They followed over 10,000 patients with diabetes type-2 for an average of about 11 years. While obese and overweight patients did have an increase in risk of strokes and heart attacks, they had a better chance of staying alive compared to diabetics with normal weight as reported in the Annals of Internal Medicine by the researchers.
Diabetics who were underweight faced the highest risk of death about thrice the mortality rate for normal weight patients. The bet survival rate was recorded for overweight patients who were 13 percent less likely to die compared to obese or normal weight diabetics.
The present result however was at odds with another study reported in the New England Journal of Medicine in 2014 which found no particular survival advantage from the extra pounds. In that study the upper end or normal weight was used for comparison. According to Dr.Costanzo, if that study had used the full range, the results likely would have been comparable to the results from the present study.
