Adolescence is a vulnerable period of life, and many mental health and behavioral problems emerge during this particular period, including depression, internet addiction (IA), and suicidal behaviors. Poor quality of life (QOL) and IA have been found to be significantly associated with suicidal ideation (SI) among Chinese university students, of whom most have been adults. Nevertheless, their associations with SI are rarely studied among Chinese adolescents. The objective of this study was to examine these relationships in a representative adolescent sample of Chinese senior high school students, who are experiencing an enormous transition from childhood to adulthood.
By using multi-stage sampling, a total of 26,688 students were successfully recruited from 29 senior high schools of a very large City in western China, Chongqing municipality. In this cross-sectional online survey, students' demographic and lifestyle characteristics were collected with a standardized questionnaire. The Young's IA Test, the Chinese Six-item QOL questionnaire, and item 15 of the Symptom Checklist-90-R were used to measure IA, QOL, and SI, respectively.
The 1-month prevalence of SI was 11.5% among students of senior high schools in Chongqing, China. Students with SI had significantly higher QOL scores (17.3 ± 3.7 vs. 13.7 ± 3.8, < 0.001) and higher prevalence of IA (49.6% vs. 25.6%, < 0.001) than those without SI. After controlling for demographic, lifestyle, and clinical covariates, IA (odd ratio (OR) = 1.15, = 0.003) and a high QOL score (OR = 1.09, < 0.001) remained significantly associated with SI.
Suicidal ideation is prevalent among Chinese adolescents and it is associated with IA and poor QOL. Measures aimed at reducing IA and improving QOL may help prevent suicidal behaviors among Chinese adolescents.
青春期是人生中的一个脆弱阶段，在此特定时期会出现许多心理健康和行为问题，包括抑郁、网络成瘾（IA）和自杀行为。在中国大学生中，生活质量（QOL）差和网络成瘾已被发现与自杀意念（SI）显著相关，其中大多数已是成年人。然而，在中国青少年中，它们与自杀意念的关联很少被研究。本研究的目的是在具有代表性的中国高中生青少年样本中检验这些关系，他们正经历从童年到成年的巨大转变。
采用多阶段抽样，从中国西部一个非常大的城市重庆市的29所高中成功招募了总共26688名学生。在这项横断面在线调查中，使用标准化问卷收集学生的人口统计学和生活方式特征。分别使用杨氏网络成瘾测试、中国六项生活质量问卷和症状自评量表90修订版的第15项来测量网络成瘾、生活质量和自杀意念。
在中国重庆高中生中，自杀意念的1个月患病率为11.5%。有自杀意念的学生比没有自杀意念的学生生活质量得分显著更高（17.3±3.7对13.7±3.8，<0.001），网络成瘾患病率也更高（49.6%对25.6%，<0.001）。在控制了人口统计学、生活方式和临床协变量后，网络成瘾（比值比（OR）=1.15，=0.003）和高生活质量得分（OR = 1.09，<0.001）仍与自杀意念显著相关。
自杀意念在中国青少年中很普遍，并且与网络成瘾和生活质量差有关。旨在减少网络成瘾和提高生活质量的措施可能有助于预防中国青少年的自杀行为。
