Attentional Bias In Patients With Type 2 Diabetes Mellitus With Different Sleep Quality

Objective To study the characteristics of attention bias in patients with type 2 diabetes mellitus with different sleep quality,and to explore the relationship between attention bias and sleep,so as to provide empirical basis for the construction of cognitive intervention program for sleep disorders in patients with type 2 diabetes mellitus.Methods Convenient sampling method was used to select 133 patients with type 2diabetes mellitus who were hospitalized in the endocrinology department of a third-class hospital in Anhui Province from May to October 2020 as study subjects to complete a point detection task with emotional face pictures as experimental materials The General Data Questionnaire,the Mini Mental State Examination Scale,the Pittsburgh Sleep Quality Index Scale,the Self-rating Anxiety Scale and the Self-rating Depression Scale were used to describe the general demographic characteristics,cognitive status,sleep quality,anxiety and depression levels of patients with type 2diabetes mellitus.The Pittsburgh Sleep Quality Index scale was used to divide the subjects’ sleep quality into three groups: good sleep quality(n = 27),general sleep quality(n = 40)and disorder(n = 66).Single sample t-test was used to explore the attention bias and its components of patients with type 2 diabetes with different sleep quality.The method of repeated measurement was used to compare the reaction time and the characteristics of attention bias in patients with type 2 diabetes mellitus with different sleep quality.Results(1)There were no significant differences in sex,residence,personal monthly income,body mass index,fasting blood glucose,two-hour postprandial blood glucose,glycosylated hemoglobin,treatment and course of diabetes among the three groups(P >0.05).There were significant differences in age,marital status,education,cognitive status,anxiety and depression(P < 0.05).(2)The three groups of patients had statistically significant differences in their reaction time to different emotional pictures under two stimulus presentation times and different cues(P < 0.05).The reaction time of general group and disorder group was significantly longer than that of good group(P< 0.05),but there was no significant difference between general group and disorder group(P > 0.05).(3)When the stimulus presented 500 ms,the negative pointing index of the disorder group was significantly greater than 0(P=0.042).When 1250 ms was stimulated,the positive disengagement index of the general group was greater than 0(P=0.032),and the positive disengagement index of the general group was significantly higher than that of the good group and the disorder group(P=0.009,P=0.029,respectively),the negative attention bias of the good group was significantly less than 0(P=0.001),the positive direction index was significantly greater than 0(P=0.002),and the positive and negative detachment indexes were significantly less than 0(P=0.011,P=0.039,respectively).The negative detachment index of the good group was significantly lower than that of the general group and the disorder group(P < 0.05).Conclusions(1)When the stimulation presented 500 ms,the type 2 diabetic patients in the sleep disorder group were alert to the negative emotional pictures,while the type 2diabetic patients in the general sleep group and good sleep group had no attention bias to the emotional pictures.(2)When the stimulation presented 1250 ms,the type 2diabetic patients in the sleep disorder group had no attention bias to the emotional pictures.The type 2 diabetic patients in the general sleep group had difficulty in paying attention to the positive emotion pictures;compared with the sleep disorder group and the good sleep group,the type 2 diabetic patients in the general sleep group had more difficulty in getting away from the positive emotion pictures.The type 2 diabetic patients in the good sleep group showed attention avoidance to both positive and negative emotional images and were quickly attracted by the positive emotional stimuli.Compared with the general sleep group and sleep disorder group,the type 2 diabetic patients in the good sleep group had more attention avoidance to the negative emotion pictures when stimulating the presentation of 1250 ms.
