大学新生限制性饮食行为与冲动性特质的关系

The Relationship between Restrictive Eating Behavior and Impulsive Traits of Freshmen

摘要: 目的：分析大学新生限制性饮食行为的状况以及与冲动性特质的关系。方法：对423名大学新生进行调查，通过荷兰进食行为问卷(DEBQ)的分量表——限制性进食分量表(DEBQ-R)筛选出限制性饮食组148人、非限制性饮食组275人，采用Barratt冲动性人格量表中文版(BIS-11)进行冲动性测试。结果：女生比男生更容易发生限制性饮食行为(χ² = 8.004, P < 0.05)，限制饮食组的BMI显著高于非限制饮食组的BMI (t = −3.502, P < 0.01)；DEBQ问卷得分与无计划冲动性成负相关(r = −0.177, P < 0.01)；非限制饮食组在运动冲动性、无计划冲动性上的得分高于限制性饮食组(F = 4.756, 7.479, P < 0.05)。结论：大学新生的限制性饮食行为与无计划冲动性特质关系密切。

Abstract: Objective: To analyze the status of restrictive eating behavior of freshmen and its relationship with impulsive characteristics. Methods: A total of 423 college students, 148 restricted eater subjects and 275 unrestricted eater subjects were selected from the Restrained Eating subscale (DEBQ-R) of Dutch eating behavior questionnaire (DEBQ), were tested on the Barratt Impulsiveness Scale-11 (BIS-11). Results: Girls are more likely to have restrictive eating behaviors than boys (χ² = 8.004, P < 0.05), and BMI of restricted diet group is significantly higher than that of unrestricted diet group (t = −3.502, P < 0.01). DEBQ-R score is negatively correlated with unplanned impulsiveness (r = −0.177, P < 0.01). The scores of exercise impulsiveness and unplanned impulsiveness in the unrestricted diet group were higher than those in the restricted diet group (F = 4.756, 7.479, P < 0.05). Conclusion: College freshmen’s restrictive eating behavior is closely related to unplanned impulsiveness.
