摘要

摘要: 目的了解广东省中小学生新冠肺炎疫情期间情绪行为问题现况及其影响因素，为制定针对性干预措施提供依据。方法于2020年3—4月，方便选取广州市、湛江市和中山市7 755名中小学生进行线上问卷调查，采用Conners父母症状问卷(PSQ)评定情绪行为问题，使用自编生活行为方式调查问卷收集中小学生的基本情况和情绪行为问题影响因素。采用χ²检验分析不同性别、学段中小学生情绪行为问题检出率的差异，采用Logistic回归模型分析情绪行为问题影响因素。结果广东省6~17岁中小学生情绪行为问题总检出率为14.8%，其中小学低年级学生、小学高年级学生、初中生和高中生情绪行为问题检出率分别为21.0%，14.4%，7.3%和10.1%。男生心身问题、多动指数检出率(3.4%，4.1%)高于女生(2.3%，2.5%)，焦虑检出率(2.8%)低于女生(4.9%)(χ²值分别为8.08，14.40，25.38，P值均 < 0.05)。不同学段学生情绪行为问题各因子异常检出率差异均有统计学意义(χ²值分别为88.88，228.00，28.28，85.19，15.66，39.33，P值均 < 0.05)。Logistic回归分析结果显示，男生存在心身问题(OR=1.37，95%CI=1.04~1.82)、多动指数(OR=1.58，95%CI=1.21~2.06)异常的风险高于女生，发生焦虑(OR=0.50，95%CI=0.39~0.64)风险低于女生; 学段是情绪行为问题各因子异常的影响因素。视屏时间过长、睡眠时长不达标的学生更易出现情绪行为问题。结论广东省中小学生在新冠肺炎疫情期间情绪行为问题检出率较高，性别、学段、视屏时间和睡眠是中小学生情绪行为问题的影响因素，应进行针对性的分类干预。

Abstract: Objective To gain a better understanding of the emotional and behavioral problems associated determinants of primary and middle school students from Guangdong Province during the COVID-19 pandemic, so as to provide a basis for developing targeted intervention strategies. Methods Using the method of convenience sampling, an online questionnaire survey was carried out among primary and middle school students from Guangzhou, Zhanjiang and Zhongshan from March to April 2020. The emotional and behavioral problems of primary and middle school students were assessed using the Conners' Parental Symptoms Questionnaire(PSQ), and a self-compiled questionnaire was used to collect basic information related to the primary and middle school students and the influencing factors of emotional and behavioral problems. A total of 7 755 valid questionnaires were retrieved and statistically analyzed using the chi-square test and multivariate Logistic regression. Results The detection rate of emotional and behavioral problems among children and adolescents aged 6 to 17-years-old in Guangdong Province was 14.8%; that was 21.0%, 14.4%, 7.3%, and 10.1% in lower primary school students, upper primary school students, junior high school students, and high school students, respectively. The detection rate of the psychosomatic and hyperactivity index in boys was higher than that observed in girls, and the detection rate of anxiety in boys was lower than that observed in girls(P < 0.05). There were statistically significant differences in emotional and behavioral problems in children in different grades(P < 0.05). The results of the regression analysis showed that male students were at risk of psychosomatic (OR=1.37, 95%CI=1.04-1.82) and hyperactivity disorders(OR=1.58, 95%CI=1.21-2.06), whereas the male gender was a protective factor for anxiety(OR=0.50, 95%CI=0.39-0.64). Grades were identified as the influencing factors of all of the factors related to emotional and behavioral problems. Students who reported excessive screen time and insufficient sleep were more likely to experience emotional and behavioral problems. Conclusion The detection rate of emotional and behavioral problems among primary and middle school students in Guangdong Province during the COVID-19 epidemic was high, which was associated with sex, grade, screen time and sleep. It is necessary to develop and implement targeted intervention measures.
