More than one-third of people with type 2 diabetes, especially older men, suffer from sleep apnea, a new study found.

Diabetic men, mainly those over the age of 62, were more than twice as likely as diabetic women to experience interrupted sleep, according to investigators at the Whittier Institute for Diabetes in La Jolla, CA. Sleep apnea occurs as a result of impaired breathing, which triggers multiple nighttime awakenings.

As a result of the findings, researchers recommend that people with type 2 diabetes be screened for obstructive sleep apnea. The study results are published in the Endocrine Practice.
