A new study has revealed that both short and long sleep durations are linked to microvascular disease in individuals newly diagnosed with type 2 diabetes mellitus (T2DM).
This research will be presented at the annual meeting of the European Association for the Study of Diabetes, scheduled from September 9 to 13 in Madrid.
The study, led by Mette S. Johansen from Odense University Hospital in Denmark, examined the relationship between sleep duration and the presence of microvascular disease in a cross-sectional analysis of newly diagnosed T2DM patients.
To measure sleep duration, participants wore accelerometers for 10 days. Sleep duration was categorized as short (less than seven hours), optimal (seven to less than nine hours), and long (at least nine hours).
Out of 396 participants with valid sleep data, the distribution was as follows: 12% had short sleep duration, 60% had optimal sleep duration, and 28% had long sleep duration. These participants also underwent urine albumin/creatinine ratio measurement and eye examinations to define microvascular disease.
The prevalence of microvascular damage within these sleep categories was 38% for short sleepers, 18% for optimal sleepers, and 31% for long sleepers. Both short and long sleep durations were significantly associated with microvascular disease, with odds ratios of 2.63 and 2.29, respectively.
Interestingly, age appeared to amplify the association between short sleep duration and microvascular disease. Younger participants (under 62 years) showed a stronger link compared to older participants.
The authors noted, “Age amplifies the association between short sleep duration and microvascular disease, suggesting increased vulnerability among older individuals.”
This study highlights the importance of maintaining an optimal sleep duration for individuals with T2DM to potentially reduce the risk of developing microvascular complications.
Further research may focus on understanding the mechanisms behind these associations and developing guidelines for optimal sleep duration to improve health outcomes in T2DM patients.
