(HealthDay News) — Compared to underweight or normal-weight people with type 2 diabetes, those who are overweight but not obese may be less likely to die over a 10-year study period, according to research published in the May 5 issue of the Annals of Internal Medicine.
Pierluigi Costanzo, MD, of the academic cardiology unit at Hull York Medical School in the United Kingdom, and colleagues collected data on 10,568 people with diabetes who were free of cardiovascular disease.
Over roughly 11 years of follow-up, the researchers found that obese and overweight people were more likely to develop cardiovascular disease, including heart failure, compared with normal-weight people. Overweight people, however, were less likely to die, compared with obese people and normal-weight individuals. Among all participants, underweight people fared worst in terms of survival.
“These results are exploratory and hypothesis-generating,” Costanzo told HealthDay. “Living a healthy lifestyle aiming to achieve weight loss should be always pursued as already indicated by guidelines.”
