Background/Objective: This study explored the association between active school travel (AST) and suicide attempts among adolescents in low- and middle-income countries (LMICs). Method: We used the data from the Global School-based Health Survey, including 127,097 adolescents aged 13-17 years from 34 LMICs. A self-reported survey was used to collect data on AST and suicide attempts as well as some variables. Multivariable logistic regression was performed to assess the association between AST and suicide attempts. A meta-analysis with random effects was undertaken to identify the difference in the association between AST and suicide attempts. Results: Across all the adolescents, the prevalence of AST was 37% and the prevalence of suicide attempts was 11.60%. Adolescents who engaged in AST were less likely to have suicide attempts irrespective of gender. The country-wise analysis indicated a large inconsistency in the association between AST and suicide attempt across the countries. Conclusions: AST would appear to be a protective factor for reducing suicide attempts among adolescents. However, the association between AST and suicide attempts varied greatly across the countries. Future studies should confirm the association between AST and suicide attempts.

背景/目的：本研究探讨了低收入和中等收入国家（LMIC）青少年的主动上学旅行（AST）与自杀未遂之间的关联。方法：我们使用了来自全球基于学校的健康调查的数据，其中包括来自34个中低收入国家的127,097名13-17岁的青少年。使用自我报告的调查收集有关AST和自杀未遂以及一些变量的数据。进行多变量logistic回归以评估AST与自杀企图之间的关联。进行了一项具有随机效应的荟萃分析，以确定AST与自杀企图之间的关联差异。结果：在所有青少年中，AST的患病率为37％，自杀未遂的患病率为11.60％。从事AST的青少年，不论性别，自杀尝试的可能性均较小。全国范围的分析表明，AST与自杀企图之间的关联在全国范围内存在很大的不一致。结论： AST似乎是减少青少年自杀未遂的保护因素。但是，AST与自杀企图之间的关联在各个国家之间差异很大。未来的研究应确认AST与自杀未遂之间的关联。
