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.

摘要： 根据记忆功能将200 例糖尿病患者分为记忆力减退组和无记忆力减退组（对照组），分析睡眠质量对糖尿病患者记忆功能的影响。结果显示，记忆力减退组有62%（62/100）患者合并睡眠障碍，高于对照组的27%（27/100；χ² = 24.800，P = 0.000）；单因素Logistic 回归分析提示伴睡眠障碍的糖尿病患者发生记忆力减退的风险明显高于睡眠正常患者（OR = 4.411，95%CI：2.425 ~ 8.024；P = 0.000）。糖尿病患者应注意改善并保持良好睡眠，以避免记忆功能障碍的发生。
