Longer sleep duration linked to progression of diabetic nephropathy
For adults with type 2 diabetes, longer sleep duration is associated with an increased risk for incidence and progression of diabetic nephropathy, according to a study published online Oct. 8 in the Journal of the Endocrine Society.
A recent study published in the Journal of the Endocrine Society suggests that adults with type 2 diabetes who sleep longer may face an increased risk of developing diabetic nephropathy and experiencing its progression. Researchers from Juntendo University Graduate School of Medicine in Tokyo conducted a prospective cohort study involving 678 Japanese outpatients aged between 25 and 70 years with type 2 diabetes.
Over a mean follow-up period of 6 years, they found that participants with a mean sleep duration of 6 to 7 hours, 7 to 8 hours, or 8 or more hours had adjusted hazard ratios of 1.56 and 1.92, respectively, compared to those sleeping less than 6 hours. The association remained significant even after adjusting for other lifestyle factors and diabetes-related factors.
Older participants and those with microalbuminuria or reduced kidney function exhibited a stronger association between longer sleep and the onset or progression of diabetic nephropathy. Dr. Tomoya Mita, co-author of the study, emphasized that while the findings suggest longer sleep duration may be an indicator that people with diabetes should be more closely monitored for kidney health, it does not imply that reducing sleep is recommended.
It is important to note that this study is observational, and cannot establish a causal relationship between sleep duration and kidney disease.
