摘要:
目的 探究高年级小学生社会时差与心理行为的关系,为促进小学生睡眠健康提供参考依据。 方法 2024年4—6月在北京市某区方便选取9所公立小学共4 341名四至五年级小学生,使用自编问卷调查小学生睡眠情况,采用长处和困难问卷(SDQ)父母版调查小学生的心理行为情况,采用广义估计方程模型分析小学生不同社会时差水平与心理行为问题得分的关联。 结果 小学生社会时差 < 1.0,1.0~< 2.0,≥2.0 h者分别占57.6%,30.6%和11.8%。广义估计方程模型分析发现,调整协变量后,与社会时差 < 1.0 h的小学生相比,社会时差在1.0~< 2.0和≥2.0 h的小学生内化行为问题得分更高[β值(95%CI)分别为0.23(0.05~0.41),0.28(0.02~0.54)],社会时差≥2.0 h的小学生外化行为问题得分更高[β值(95%CI)=0.42(0.13~0.71)](P值均 < 0.01)。在男生、平均夜间睡眠时长≥9 h的小学生中,与社会时差 < 1.0 h者相比,社会时差1.0~< 2.0 h的小学生内化行为问题、外化行为问题得分更高[β值(95%CI)分别为0.32(0.07~0.56),0.51(0.11~0.90),0.26(0.06~0.46),0.58(0.25~0.91),P值均 < 0.05]。 结论 社会时差较大可能是高年级小学生发生内、外化行为问题的风险因素,缩小社会时差可能有助于减少小学生心理行为问题的发生。 Abstract:Objective To investigate the correlation between social jetlag and psychological behavior in upper primary school students, so as to provide reference for sleep health promotion in primary school students. Methods From April to June 2024, a survey was conducted among 4 341 fourth- and fifth-grade students from 9 public primary schools in a district in Beijing. Sleep patterns were assessed using a self-designed questionnaire, while psychological behavior was evaluated using the Strengths and Difficulties Questionnaire (SDQ)(parent version). A generalized estimating equation (GEE) model was used to examine the association between different levels of social jetlag and psychological behavior problem scores in primary school students. Results The proportions of students with social jetlag of < 1.0, 1.0- < 2.0, and ≥2.0 h were 57.6%, 30.6%, and 11.8%, respectively. The GEE model analysis found that after adjusting for covariates, compared with primary school students with social jetlag of < 1.0 h, those with 1.0- < 2.0 and ≥2.0 h had higher scores for internalizing behavior problems [β(95%CI) =0.23(0.05-0.41), 0.28(0.02-0.54), P < 0.01]. Primary school students with ≥2.0 h of social jetlag had higher scores for externalizing behavior problems [β(95%CI)=0.42 (0.13-0.71), P < 0.01]. Among boys and primary school students with an average nighttime sleep duration of ≥9 h, comparied with social jetlag of < 1.0 h, those with sucial jetlag 1.0- < 2.0 h had higher scores on internalizing and externalizing behavior problems[β(95%CI)=0.32(0.07-0.56), 0.51 (0.11-0.90), 0.26 (0.06-0.46), 0.58 (0.25-0.91), P < 0.05]. Conclusions Greater social jetlag may be a risk factor for internalizing and externalizing behavior problems in upper primary school students. Reducing social jetlag may help decrease the occurrence of psychological behavior problems in primary school students. -
