NHANES: HbA1c associated with mortality risk in older adults

NHANES: HbA1c associated with mortality risk in older adults
February 27, 2017

In older adults, an HbA1c greater than 8% was associated with increased risks for all-cause, cardiovascular and cancer-related deaths, according to an analysis of National Health and Nutrition Examination Survey data.

“Few studies have had sufficient data to assess the association between HbA1c and mortality in an exclusive sample of adults aged 65 years and older with and without diabetes, a population at potentially higher risk of adverse diabetes-related complications,” Priya Palta, PhD, associate professor in the department of epidemiology at the Johns Hopkins School of Public Health, and colleagues wrote. “Largely, data on the benefits and outcomes associated with HbA1c lowering remain heterogeneous, particularly among populations of older adults. Therefore, more studies of the HbA1c–mortality relationship are needed to affirm the current clinical practice recommendations and guidelines related to the care of diabetes for older adults.”
