Obesity paradox on the survival of elderly patients with diabetes: an AHAP-based study

摘要

Background and objectivesOverweight and obesity are among the important challenges in health issues and survival of elderly people. The current study aimed to evaluate the survival rate of elderly patients with diabetes, and its influencing factors, on the basis of body mass index (BMI). Methods and materialsThe design of the current study was based on the Amirkola Health and Aging Project (AHAP) cohort. The 5–year survival rate of elderly people with diabetes and the factors that influence the mortality rate by Cox regression model were analyzed. ResultsOut of 1616 elderly people who were evaluated in the current study, 501 (31%) had diabetes. The results showed that diabetes significantly increased the mortality rate (adjusted hazard ratio [HR]?=?2.10; 95% confidence interval [CI]: 1.57–2.81; P ConclusionAlthough overweight and obesity significantly improved the risk of mortality in elderly patients with diabetes, central obesity is still considered as an important risk factor.
