Research On The Characteristics Of Inhibitory Control In Type 2 Diabetic Patients With Different Levels Of Dietary Adherence

Objective The stop signal task of inhibition control cognitive behavioral paradigm was used to expore the characteristics of inhibition control in type 2 diabetic patients with different level dietary adherence.To understand the relationship between inhibition control processing and dietary adherence behavior.To provide empirical basis for the intervention of inhibitory control training to improve the dietary adherence behavior of patients with type 2 diabetes.Methods Convenient sampling method was used to select 190 patients with T2DM who were admitted in the endocrinology department of third-class in Anhui Province from May to September 2019.Questionnaires and behavioral experiments were conducted on a one-to-one basis.Questionnaire survey:the General Information Questionnaire was used to collect the general demographic and disease data of patients,and the patients were divided into three groups of high,medium and low level of dietary adherence according to the scores of the Food Control Behavior Scale.Behavioral experiments:E-prime software was used to design experimental programs.The experimental materials were from a self-established picture library.30 each of high energy food pictures,low energy food pictures and neutral pictures were selected based on the familiarity,pleasure,liking and arousal scores.The behavioral experiment choosed the stop signal task and recorded the response time and accuracy rate of patients in different categories of pictures stimulus in stop signal task.3?group:low,medium,high level of dietary adherence group?×3?picture categories:low-energy food pictures,neutral pictures,high-energy food pictures?two-factor repeated measures analysis of variance was used to compare the inhibitory control characteristics of patients with different level of dietary adherence under different categories of picture stimulus stop signal tasks.Results?1?T2DM patients with different levels dietary adherence showed no statistically significant differences in age,gender,residence,marital status,education,family monthly income,anxiety and depression level,hunger state,fasting blood glucose,2-hour postprandial blood glucose and treatment methods?P>0.05?;there were statistically significant differences in duration of disease,BMI and Hb A₁c?P<0.05?.?2?T2DM patients with different levels dietary adherence in no stop signal response time under three categories of picture stimulus conditions:different levels of dietary adherence groups showed no statistically significant differences in no stop signal response time under three categories of picture stimulus conditions?P>0.05?;low level of dietary adherence group showed shorter no stop signal response time under food picture stimulus conditions than under neutral picture stimulus condition?P<0.05?,while medium and high level of dietary adherence groups both showed no statistically significant differences in no stop signal response time under three categories of picture stimulus conditions?P<0.05?.?3?T2DM with different level dietary adherence in stop signal response time under three categories of picture stimulus conditions:different levels of dietary adherence groups showed statistically significant differences in stop signal response time under food picture stimulus conditions?P<0.05?.low level of dietary adherence group showed longer stop signal response time than medium and high level of dietary adherence group under high and low energy food picture stimulus conditions?P<0.05?.low and medium level of dietary adherence groups both showed longer stop signal response time under food picture stimulus conditions than under neutral picture stimulus?P<0.05?,while high level of dietary adherence groups showed no statistically significant differences in stop signal response time under different categories of picture stimulus conditions?P>0.05?.?4?T2DM patients with different levels of dietary adherence in accuracy rate under three categories of picture stimulus conditions:different level of dietary adherence groups showed no statistically significantly differences in the no stop signal accuracy rate and failure inhibition rate under three categories of picture stimulus conditions?P>0.05?.Conclusions?1?comparison of inhibition control in T2DM patients with high,medium and low level of dietary adherence:high,medium and low level of dietary adherence groups showed no difference in the response speed under different categories of picture stimulus conditions;high,medium and low level of dietary adherence showed differences in inhibition control ability under food picture stimulus conditions,and low level of dietary adherence group showed worse inhibition control ability than medium and high level of dietary adherence groups.medium and high level of dietary adherence groups showed no difference in inhibition control ability.?2?The characteristics of inhibition control in T2DM patients with low level of dietary adherence:low level of dietary adherence group compared to neutral picture stimulus condition,the impulsive response increased and the inhibition control ability decreased under food picture stimulus conditions.?3?The characteristics of inhibition control in T2DM patients with medium level of dietary adherence:medium level of dietary adherence group showed no difference in response speed under different categoriesof picture stimulus conditions,and inhibition control ability under food picture stimulus condition was worse than neutral picture stimulus condition.?4?The characteristics of inhibition control in T2DM patients with high level of dietary adherence:high level of dietary adherence group showed no difference in response speed and inhibition control ability under different categories of picture stimulus conditions.
