摘　　要：目的考察大学生自杀意念的动态发展轨迹及其相关因素。方法在2019—2021年间,采用方便取样的方法,每年10月对广东省某高校1438名学生进行3次纵向追踪。采用自杀意念自评量表(SIOSS)测量自杀意念水平,使用潜变量混合增长模型(LGMM)分析大学生自杀意念发展轨迹,建立多元logistic回归模型,分析自杀意念各潜在类别变化的相关因素。结果2019—2021年间,大学生自杀意念总分分别为3.79±2.87、3.71±2.90、3.32±2.87,随时间呈现一定的下降趋势;大学生自杀意念的发展轨迹可划分为3个类别:C1自杀意念加重组(11.8%)、C2持续低自杀意念组(79.6%)、C3自杀意念缓解组(8.6%);相对于C1组,童年生活一般(OR=2.52,95%CI:1.31~4.86)或童年生活幸福(OR=3.95,95%CI:2.02~7.74)、无自杀未遂史(OR=9.03,95%CI:3.49~23.36)、外向(OR=1.03,95%CI:1.01~1.05)的大学生更容易进入C2组,而生源地为城市(OR=0.54,95%CI:0.31~0.93)、神经质得分高(OR=0.86,95%CI:0.84~0.88)的大学生更不容易进入C2组;童年生活幸福(OR=3.29,95%CI:1.40~7.74)的大学生更容易进入C3组,而生源地为城市(OR=0.37,95%CI:0.18~0.78)的大学生更不容易进入C3组。结论大学生自杀意念的发展轨迹可划分为3个类别:自杀意念加重组、持续低自杀意念组、自杀意念缓解组,自杀意念的发展轨迹与生源地、童年生活、自杀史、人格特质等因素相关。Objective Background Suicide has become a major public health issue of global concern.Suicidal ideation represents the initial psychological and one of the strongest predictorsactivities associated with suicidal behavior.Suicidal ideation is a dynamic state factor rather than a static trait factor,so it is necessary to study the development trajectory of suicidal ideation and its related factors.Objective To investigate the development trajectory and relatedfactors of suicide ideation college students.Methods From 2019 to 2021,1438 college students in a university in Guangdong Province were selected for three longitudinal tracking each October by using the method of convenient sampling.The Self-rating ideas of suicide scale(SIOSS)was used to measure the level of suicide ideation.Data analysis was mainly based on the Latent Growth Mixed Model(LGMM)to analyze the development trajectory of students'suicide ideation.Multivariate Logistic Regression model was established to analyze the related factors to the variation of each potential category of suicidal ideation.Results From 2019 to 2021,the total scores of college students'suicidal ideation were 3.79±2.87,3.71±2.90 and 3.32±2.87,showing a decreasing trend over time.The development tendencies of college students'suicide ideation have been classified into 3 categories:Cl group(worsening suicidal ideation group)(11.8%),C2 group(persistent low suicidal ideation group)(79.6%),and C3 group(relieving suicidal ideation group)(8.6%).Compared with Cl group,college students who had an average(OR=2.52,95%CI:1.31-4.86)or happy childhood(OR=3.95,95%CI:2.02-7.74),no history of suicide attempt(OR=9.03,95%CI:3.49-23.36),and were extroverted(0R=1.03,95%CI:1.01-1.05)were more likely to enter C2 group.Students who were from cities(OR=0.54,95%CI:0.31-0.93),got high neuroticism scores(OR=0.86,95%CI:0.84-0.88)were less likely to enter the C2 group.College students with happy childhood life(OR=3.29,95%CI:1.40-7.74)were more likely to enter the C3 group,but students from cities(OR=0.37
