A recent study reveals that sleep disturbances are associated with insulin resistance and incidence of type 2 diabetes in senior adults, as reported by Diabetes In Control.

Sleep-disordered breathing (SDB), which includes loud snoring, stopping breathing for a while during sleep, and daytime sleepiness, and insomnia, has been linked to impaired glucose metabolism, insulin resistance, and an increase in incidence of type 2 diabetes (T2DM) in older adults. In this study, the authors consider the symptoms of both SDB and insomnia in their association with glucose metabolism in older populations.

A total of 5,888 participants over the age of 65 were recruited for this study. Participants were asked to report symptoms of SDB and insomnia. Symptoms of SDB were categorized as “observed apnea,” “bothersome snoring,” and “daytime sleepiness.” Insomnia symptoms include “sleep initiation problems,” sleep maintenance problems,” or “early morning awakenings.” In addition, an oral glucose tolerance test (OGTT) was performed to obtain fasting blood glucose and 2-h glucose value.
