In adolescents, multiple unhealthy behaviors frequently occur together and are likely to be associated with suicidal behaviors (SBs), increasing the risk of suicide. This study aimed to clarify the potential patterns of unhealthy behaviors in Chinese adolescents and to examine the associations between the different patterns of unhealthy behaviors and SBs.
A total of 22,628 middle school students were enrolled in this study. Self-reported unhealthy behaviors and SBs were investigated using questionnaires. Latent class analysis (LCA) was performed based on five unhealthy behaviors [smoking, alcohol use (AU), diet pill use (DPU), screen time (ST), and problematic mobile phone use (PMPU)]. Multivariate logistic regressions were used to examine associations between the different patterns of unhealthy behaviors and SBs.
Four subgroups of unhealthy behaviors were identified by LCA, including high-risk class (smoking/AU/DPU/PMPU/ST), moderate-risk class 1 (DPU/PMPU), moderate-risk class 2 (smoking/AU/ST), and low-risk class. Compared with the low-risk class, moderate-risk class 1, moderate-risk class 2, and high-risk class had higher risks of suicidal ideation, suicide plan, and suicide attempt.
These findings suggested that patterns of unhealthy behaviors were related to SBs in Chinese adolescents. Accordingly, considerations of different classes of unhealthy behaviors may be essential for developing effective preventive programs.
在青少年中，多种不健康行为经常同时出现，且可能与自杀行为（SBs）相关，增加了自杀风险。本研究旨在明确中国青少年不健康行为的潜在模式，并探讨不同模式的不健康行为与自杀行为之间的关联。
本研究共纳入22628名中学生。使用问卷对自我报告的不健康行为和自杀行为进行调查。基于吸烟、饮酒（AU）、使用减肥药（DPU）、屏幕使用时间（ST）和问题手机使用（PMPU）这五种不健康行为进行潜在类别分析（LCA）。采用多变量逻辑回归分析不同模式的不健康行为与自杀行为之间的关联。
通过潜在类别分析确定了四个不健康行为亚组，包括高风险组（吸烟/饮酒/使用减肥药/问题手机使用/屏幕使用时间）、中度风险组1（使用减肥药/问题手机使用）、中度风险组2（吸烟/饮酒/屏幕使用时间）和低风险组。与低风险组相比，中度风险组1、中度风险组2和高风险组有更高的自杀意念、自杀计划和自杀未遂风险。
这些发现表明，不健康行为模式与中国青少年的自杀行为有关。因此，考虑不同类别的不健康行为对于制定有效的预防方案可能至关重要。
