基于潜在类别分析的女大学生童年期创伤与进食障碍的关联研究

目的 探索女大学生童年期创伤的潜在类别,并进一步探究其与进食障碍的关联。方法 采用一般资料调查表、儿童期创伤问卷和进食态度量表,于2020年12月在山东省济南市选取3所院校共计655名女大学生开展问卷调查。对童年期创伤经历进行潜在类别分析,并采用多因素logistic回归分析探讨不同类别与进食障碍的关联性。结果 女大学生童年期创伤分为无/低创伤组（73.9%）、高创伤组（4.3%）和高忽视组（21.8%）。调整自评人际关系、自评学习压力后,多因素logistic 回归分析结果显示,高创伤组（OR = 12.771,95%CI:5.555～29.360,P＜0.01）和高忽视组（OR = 4.530,95%CI:2.935～6.992,P＜0.01）与进食障碍存在关联。结论 女大学生童年期创伤具有明显的类别特征,且高创伤组和高忽视组是进食障碍的危险因素,今后应精准识别童年期创伤的潜在类别以便制定有针对性的方案干预进食障碍。

The association between childhood trauma and eating disorders in female college students based on latent classes analysis

Objective To explore the latent classes of childhood trauma in female college students, and to further explore the relationship between childhood trauma and eating disorders. Methods Using a general information questionnaire, childhood trauma questionnaire and eating attitude scale, a total of 655 female college students selected from three colleges in Jinan, Shandong Province were surveyed in December 2020. Latent class analysis of childhood trauma experiences was conducted, and multi-factor logistic regression analysis was used to explore the association of different categories with eating disorders. Results Female college students were divided into no/low trauma group (73.9%), high-incidence trauma group (4.3%), and highly neglected group (21.8%) in terms of childhood trauma. After adjusting for self-rated interpersonal relationships and self-rated academic stress, multifactorial logistic regression analysis showed that the high-incidence trauma group (OR=12.771, 95%CI: 5.555-29.360, P<0.01) and the highly neglected group (OR=4.530, 95%CI: 2.935-6.992, P<0.01) were associated with eating disorders. Conclusion Childhood trauma in female college students has obvious category characteristics, and the high - incidence trauma and being highly neglected are risk factors for eating disorders. In the future, the potential categories of childhood trauma should be precisely identified in order to develop targeted programs to intervene in eating disorders.
