Abstract:
Objective:To analyze the association between sleep chronotype and suicidal psychological behaviors among middle school students, so as to provide a scientific basis for the prevention and control of middle school students suicide.
Methods:In October 2021 and November 2022, a multistage cluster sampling method was used to conduct baseline and followup surveys in Shenyang, Zhengzhou, Nanchang, and Taiyuan cities in China, and a total of 6 656 middle and high school students were included as the research subjects. The Chisquare test was used to analyze the groups differences, and generalized estimating equation was used to analyze the associations between middle school students sleep chronotype and suicide ideation, suicide plan and suicide attempt, and the grade stratification was carried out.
Results:Baseline detection of suicide ideation, suicide plan, and suicide attempt were 26.3%, 12.6%, and 5.3%, respectively, with followup rates of 21.0%, 10.0%, and 4.8% for each, and varied significantly by gender, academic stress, smoking or alcohol use, and anxiety or depressive symptoms among middle school students (χ2=11.93-880.20, P<0.05). After adjusting for gender, academic stress, physical activity, smoking, alcohol use, anxiety and depressive symptoms, generalized estimating equations showed that compared with the morning sleep chronotype, the OR(95%CI) for suicide ideation, suicide plan and suicide attempt were 1.61(1.36-1.89), 1.66(1.35-2.05) and 1.41(1.06-1.88) among evening chronotype students, and were higher among junior 1.78(1.39-2.27), 2.00(1.48-2.69) and senior middle school students 1.84(1.44-2.35), 1.67(1.20-2.33) (P<0.05).
Conclusion:There is a positive association between evening sleep chronotype and middle school students suicidal psychological behavior, and improving sleep chronotype may be one of the effective measures to prevent middle school students suicide.
