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.
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.
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].
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.
