Methods CHD patients were proved by coronary arteriongraphy. 64 patients with type 2 diabetes in combination with CHD were enrolled in group A and 98 patients with simple CHD served as group B. Patients of group A were subdivided into 3 groups based on scalar of the stenotic coronary artery, viz 1 rarnus, 2 rami and 3 rami affection groups, and urinary albumin level was determined. In group A, age, course of DM, BMI, BP, BS, GHbA1c, blood-fat, UAL serving as iv, and affection sum and stenosis index serving as dv, ran polynary gradual regressive analysis.
随机选取经冠状动脉造影确诊的冠心病患者,其中2型糖尿病合并冠心病患者64例为A组,单纯冠心病患者98例为B组,比较两组患者的临床资料和冠状动脉病变情况。A组患者根据冠脉病变支数分为3个亚组,即l支、2支、3支病变组,比较亚组间的尿白蛋白水平;A组患者以年龄、体质量指数、糖尿病病程、血压、血糖、糖化血红蛋白、血脂、尿白蛋白为自变量,分别以病变数、冠脉狭窄指数为因变量进行多元逐步回归分析。

objective to study the correlation among psychosomatic health factors,depression,anxiety and sleep status in college students,to analyze influence factors in sleep status.methods with questionnaire opened in-vestigation,200college students were evaluated using cornell medical index,self-rating depression,self-rating anxiety scaleand pittsburgh sleep quality index.stepwise regression analysis was used.re-sults total score of sds was35.55±7.8,and sas was0.48±0.9.each score of cmi was higher than normal range,the highest was digestion system,next was respiration system,then,fatigue,eyes and ears,anxiety,sensitivity,tension,maladjustment in turn.total average score of psqi was6.32±3.6,ordinary sleep were115cases(57.5%),good and bad sleep were42(21%)and43(21.5%)cases respectively.influence factors in total score of psqi were sas,cmi,respiration system,anxiety,past healthy,digestion system,fatigue,sensitivity,sds and malad-justment in turn,using stepwise regression analysis,total score of psqi as dependent variable,each factor score of cmi,total score of sds and sas as independent variables.conclusion problems of psychosomatic health,anxiety and depression could both lead to sleep disorder.
目的 研究在校大学生心身健康因素及抑郁焦虑等与睡眠状况的相关性,并对影响睡眠状况的有关因素进行分析。方法采用问卷式的开放性研究,对在校的200名大学生进行康奈尔心身健康问卷、自评抑郁量表、焦虑自评量表和匹兹堡睡眠质量量表的测定,采用逐步回归分析方法。结果 sds总分为35.55±7.8、sas总分为0.48±0.9,cmi评分:消化系统最为严重评分为2.52,其次为呼吸系统、疲劳感、眼和耳、焦虑、敏感、紧张、不适应等,评分均高于正常常模。psqi总均分为6.32±3.6,一般睡眠有115例占57.5%,睡眠质量较好42例占21.0%,睡眠质量较差43例占21.5%。评估对睡眠状况的影响程度,以psqi总分为因变量,选择cmi各因子分和sds、sas总分作为自变量,进行多因素逐步回归分析,进入方程的因素依据标准化偏回归系数,影响psqi总分的因素依次为sas总分、cmi总分、呼吸系统、焦虑、既往健康、消化系统、疲劳感、敏感、sds总分、不适应(f=226.8;p.01;r=0.73)。结论心身健康问题和焦虑抑郁可导致睡眠障碍。
