摘要:
目的 对中学生遭受校园欺凌的影响因素进行分析,构建列线图模型预测遭受校园欺凌的风险,为防控中学生遭受校园欺凌提供理论依据。 方法 于2023年9月,在内蒙古地区12个盟市(103个旗县)范围内通过分层整群随机抽样方法抽取89 117名中学生进行自填问卷调查,其中训练集62 381名,测试集26 736名。采用χ2检验和多元Logistic回归进行统计学分析并绘制列线图进行校园欺凌预测。 结果 中学生校园欺凌的报告率为3.49%。生活在郊县、处于非稳定家庭、非独生子女、父亲学历大学及以上、有时吃或从不吃早餐、超重肥胖、住校、过去30 d被家长打骂、吸烟、网络成瘾、有抑郁症状、有焦虑症状、为了高兴使用可溶性溶剂、除咳嗽外使用止咳剂、无医生许可使用镇静剂与中学生遭受校园欺凌均呈正相关(OR值分别为1.18,1.40,1.12,1.33,1.13,1.72,1.12,1.17,1.82,1.32,1.83,3.92,2.40,2.25,1.51,1.63),高中生、女生、每周体育课节数(2~3,≥4)与中学生遭受校园欺凌均呈负相关(OR值分别为0.67,0.58,0.72,0.83)(P值均 < 0.01)。基于以上影响因素建立校园欺凌风险列线图的预测模型,曲线下面积(AUC)为0.82,校准曲线显示预测值与实际值接近。 结论 中学生遭受校园欺凌与家庭亲密度、不良日常行为、心理因素等有关。应有效识别校园欺凌干预对象,制定中学生遭受校园欺凌的防控策略,降低校园欺凌的发生。 Abstract:Objective To analyse associated factors of campus bullying in schools, and to construct a nomogram model to predict the risk of campus bullying, so as to provide a theoretical basis for campus bullying prevention and control. Methods In September 2023, 89 117 middle and high school students were selected by stratified cluster random sampling method within 12 cities (103 counties) in Inner Mongolia, and were surveyed with self-administered questionnaire. Among them, there were 62 381 participants in the training set and 26 736 participants in the testing set. Statistical analysis was conducted using χ2 test and multiple Logistic regression, and a nomogram model was drawn for predicting campus bullying. Results The prevalence of campus bullying was 3.49%. Living in a suburban county, living in an unstable family, not the only child, having a father with a college degree or above, sometimes or never eating breakfast, being overweight or obese, living on campus, being scolded by parents in the past 30 days, smoking, Internet addiction, experiencing depression, anxiety symptoms, recreational soluble solvents use, cough medicine abuse, nonprescribed use of sedatives were all positively correlated with campus bullying (OR=1.18, 1.40, 1.12, 1.33, 1.13, 1.72, 1.12, 1.17, 1.82, 1.32, 1.83, 3.92, 2.40, 2.25, 1.51, 1.63, P < 0.01).There were a negative correlation between high school students, female students, and the number of physical education classes per week (2-3, ≥4) with campus bullying (OR=0.67, 0.58, 0.72, 0.83, P < 0.01). The prediction model of campus bullying risk was established by nomogram model. The area under curve (AUC) was 0.82, and the calibration curve showed that the predicted value was close to the actual value. Conclusions Bullying among middle and high school students are related to family intimacy, poor daily behaviour and psychological factors. Targets of bullying intervention in schools should be identified, and preventive and control measures against bullying in secondary schools should be formulated, so as to reduce the occurrence of campus bullying. -
