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 multi-stage cluster sampling method was used to conduct baseline and follow-up 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 Chi-square 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 at-tempt,and the grade stratification was carried out.Results Baseline detection of suicide ideation,suicide plan,and suicide at-tempt were 26.3％,12.6％,and 5.3％,respectively,with follow-up rates of 21.0％,10.0％,and 4.8％for each,and varied signif-icantly by gender,academic stress,smoking or alcohol use,and anxiety or depressive symptoms among middle school students(x2=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 eve-ning 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 pre-vent middle school students suicide.
