Prevalence and correlates of insomnia and fatigue in patients with type 2 diabetes in Jordan

Abstract

Objective: The present study examined the prevalence and correlates of insomnia and fatigue in patients with type-2 diabetes in Jordan. Methods: This was a cross-sectional online study involving a convenience sample of 390 patients with type-2 diabetes. Insomnia was assessed by the Insomnia-Severity Index (ISI-A) and fatigue by the Brief Fatigue Inventory (BFI-A). Results: Severe insomnia was present in 132 patients (33.8%), and was correlated with length of diabetes (diagnosis >5 years) (OR = 2.13, 95% CI = 1.19-3.81, P = 0.01), presence of uncontrolled diabetes (OR = 1.97, 95% CI = 1.45-2.69, P < 0.001), taking gabapentin (OR = 2.07, 95% CI = 1.07-4.01, P = 0.003), and age (<40 years) (OR = 0.30, 95% CI = 0.13-0.69, P = 0.005). Significant fatigue was also prevalent and correlated with gender (female) (B = 9.25, t = 4.48, P < 0.001), age (<40 years) (B = 7.56, t = 2.56, P = 0.01), a diagnosis of hypertension (B = 4.74, t = 2.03, P = 0.04), uncontrolled diabetes (B = 7.21, t = 4.82, P < 0.001), and taking a sulfonylurea (B = 8.03, t = 3.37, P < 0.001), carbamazepine (B = 10.93, t = 2.65, P = 0.008), or gabapentin (B = 12.60, t = 3.83, P < 0.001). Conclusion: Given the high prevalence of insomnia and fatigue in this population, increased attention by primary healthcare providers to these symptoms in diabetic patients is required, particularly in developing countries such as Jordan.
