Suicide is a global public health crisis, and little evidence has focused on associations between suicide attempts and childhood maltreatment (CM) in Chinese middle school students.
This study aimed to explore the relationship between childhood maltreatment and suicide attempts and the sex difference in Chinese middle school students.
In this prospective cohort study, students in grades 7 and 8 filled out the questionnaire at baseline and 6-month follow-up.
Demographic data, childhood maltreatment, and suicide attempts were surveyed. Depression, anxiety, and stress were measured at baseline as covariates. Logistic regression was employed to measure the impact of childhood maltreatment and its sex differences on suicide attempts.
Among 782 students, 39.6 % suffered from childhood maltreatment, and the incidence rate of suicide attempts in 6 months was 4.60 % (36/782). After controlling for covariates, childhood maltreatment (adjusted odds ratio, OR = 2.899, 95%CI = 1.349-6.227) and its subtypes, physical abuse (adjusted OR = 4.077, 95%CI = 1.593-10.505) and emotional neglect (adjusted OR = 2.179, 95%CI = 1.059-4.481) were independent risk factors of suicide attempts. The association remained significant in females but not males, while no interactions between sex and childhood maltreatment were found.
Childhood maltreatment was prevalent in Chinese middle school students and closely associated with the incidence of suicide attempts, which provided valuable evidence for suicide prevention.
自杀是全球公共卫生危机，很少有证据关注自杀未遂与中国中学生童年期虐待（CM）之间的关系。
本研究旨在探讨中国中学生童年期虐待与自杀未遂之间的关系及其性别差异。
在这项前瞻性队列研究中，7 年级和 8 年级的学生在基线和 6 个月随访时填写了问卷。
调查了人口统计学数据、童年期虐待和自杀未遂情况。在基线时测量了抑郁、焦虑和压力作为协变量。采用逻辑回归来衡量童年期虐待及其性别差异对自杀未遂的影响。
在 782 名学生中，39.6%遭受过童年期虐待，6 个月内自杀未遂的发生率为 4.60%（36/782）。在控制了协变量后，童年期虐待（调整后的优势比，OR=2.899，95%CI=1.349-6.227）及其亚型，身体虐待（调整后的 OR=4.077，95%CI=1.593-10.505）和情感忽视（调整后的 OR=2.179，95%CI=1.059-4.481）是自杀未遂的独立危险因素。这种关联在女性中仍然显著，但在男性中不显著，而性别与童年期虐待之间没有交互作用。
童年期虐待在中国中学生中很普遍，与自杀未遂的发生率密切相关，为预防自杀提供了有价值的证据。
