Certain factors are linked to sleep disturbance in patients with type 2 diabetes

Journal of Advanced Nursing study recommends that clinicians should pay extra attention to females with type 2 diabetes when conducting sleep-related assessments.

The study examined whether diabetes-related symptoms (e.g. fatigue, neuropathic pain, diabetes distress and depressive symptoms) were related to sleep disturbance and sleep-related impairment in adults with type 2 diabetes.

 

It found that of 90 adults with type 2 diabetes, female gender, elevated blood sugar levels, neuropathic pain, and fatigue were related to sleep disturbance, even after controlling for factors such as age, diabetes duration, depressive symptoms, and distress.

 

The findings suggest that clinicians should pay extra attention to females when conducting sleep-related assessments.

 

A comprehensive sleep evaluation should also include diabetes-related symptoms such as neuropathic pain and fatigue. 

 

"Sleep disturbance in patients with diabetes is common and may negatively affect blood glucose," said senior author Dr. Cynthia Fritschi, of the University of Illinois at Chicago College of Nursing.

 

"A thorough sleep assessment, especially in female adults, must include a symptom assessment. To do otherwise limits our ability to treat sleep disturbance effectively in this population."

 

Study Abstract

Aim

The objective of this study was to examine whether diabetes-related symptoms (e.g. fatigue, neuropathic pain, diabetes distress and depressive symptoms) were related to sleep disturbance and sleep-related impairment in adults with type 2 diabetes while controlling for potential covariates.

 

Background

In people with type 2 diabetes, sleep disturbance and sleep-related impairment are common and likely associated with diabetes-related symptoms. However, limited research has investigated the predictive ability of diabetes-related symptoms on sleep.

 

Design

A correlational, cross-sectional design was used.

 

Methods

Data were collected at a large university in the Midwestern United States from September 2013-March 2014. Multiple linear regression analyses were used to examine the relationship of diabetes-related symptoms (fatigue, neuropathic pain, distress and depressive symptoms) to sleep disturbance and sleep-related impairment. The instruments included Patient-Reported Outcomes Measurement Information System instruments, Diabetes Symptom Checklist and Diabetes Distress Scale.

 

Findings

In this study of adults with type 2 diabetes (N = 90; 52.2% female, mean age 57.4 years), gender, A1C, neuropathic pain and fatigue were significantly related to sleep disturbance when age, diabetes duration, depressive symptoms and distress were controlled. Those variables collectively explained 52% of the variation in sleep disturbance. Fatigue was significantly associated with sleep-related impairment when the same covariates were controlled.

 

Conclusion

Findings suggested that diabetes-related symptoms, including neuropathic pain and fatigue, are strongly related to sleep disturbance and sleep-related impairment in adults with type 2 diabetes, underscoring the need to include detailed assessments of neuropathic pain and fatigue when evaluating sleep.
