Effects of sleep quality on the memory function of diabetic patients

Abstract

Objective To investigate the influence of sleep quality on the memory function of diabetic patients.  Methods Two hundred diabetic patients were investigated by questionnaires. They were divided into control group with normal memory function (N = 100) and observation group with abnormal memory function (N = 100) according to their performance in the test. The relationship between sleep quality and memory function was analyzed.  Results Sixty-two diabetic patients (62% ) in observation group had poor sleep quality, while only 27 diabetic patients (27%) in control group had poor sleep quality, and the difference was statistically significant ( χ² = 24.800, P = 0.000). Univariate Logistic regression analysis indicated that diabetic patients with poor sleep quality had significantly higher risk of dysmnesia than those with normal sleep quality (OR = 4.411, 95%CI: 2.425-8.024; P = 0.000).  Conclusions It is necessary to improve sleep quality in diabetic patients to avoid their decrease of memory function.
