Purpose:
The purpose of this study was to examine the relationships between symptom burden and sleep problems and the role of depressive symptoms on these relationships in middle-aged and older adults with type 2 diabetes.
Methods:
The study employed a cross-sectional, correlational design with secondary analysis. De-identified data sets from three original studies were combined. A total of 189 men and women with type 2 diabetes were recruited using convenience sampling in midwestern United States. Symptom burden, sleep impairment and sleep disturbance, depressive symptoms, demographics, and diabetes-related variables were assessed. The participants were grouped into glucose-controlled and -uncontrolled groups to examine a multigroup effect. Multigroup path analyses were conducted.
Results:
The results indicated that symptom burden had direct and indirect effects through depressive symptoms on sleep disturbance in the controlled group, whereas only a direct effect was found in the uncontrolled group. For sleep-related impairment, significant direct and indirect effects of symptom burden were found via depressive symptoms in both groups, and the strength of the effects on each path differed between the groups.
Conclusions:
Diabetes symptom burden was associated with sleep disturbance and sleep-related impairment in middle-aged and older adults with diabetes. A different approach should be considered for sleep management according to their A1C levels, and depressive symptoms can be a therapeutic target to treat sleep problems in the population.
