Adults with prediabetes who reported sleeping 5 hours or less per night were nearly 70% more likely to progress to type 2 diabetes over 2 years compared with those who reported sleeping 7 hours each night, according to findings from a study conducted in South Korea.
“Previous studies have shown that sleep deprivation is associated with risk of development of diabetes,” Chan-Won Kim, MD, of the Center for Cohort Studies at Total Healthcare Center, Kangbuk Samsung Hospital, Seoul, South Korea, told Endocrine Today. “However, these studies defined diabetes based on self-report, which may influence this association, and no studies have investigated the association between sleep duration and progression of prediabetes to diabetes. We studied if insufficient sleep would be linked to an increased risk of progression to diabetes among persons with prediabetes, defined by HbA1c concentration. We found that short sleep duration was associated with progression of prediabetes to diabetes, independent of socioeconomic factors and lifestyle characteristics.”
