Binge drinking, notably common among university students, poses health risks. Despite a significant global concern about suicide, especially among young people, research on the connection between binge drinking and suicide in university students is limited. This cross-sectional study investigated the relationship between binge drinking, suicidal attempts, and suicidal thoughts among university students from two institutions. Among the 2178 participants from public universities, 4.0% reported suicidal attempts, and 26.5% reported suicidal thoughts. Binge drinking did not show a significant association with suicidal attempts or suicidal thoughts. The results revealed that female gender (OR 1.62, 95% CI: 1.32–2.01; p < 0.001) and alcohol use disorder (OR 2.23, 95% CI: 1.49–3.55; p < 0.001] were independent predictive variables for suicidal behavior. These findings underscore the need for targeted interventions addressing alcohol-related behaviors and mental health, particularly among females and those with alcohol use disorder, to enhance the overall psychological well-being of university students.

酗酒在大学生中尤其常见，会带来健康风险。尽管全球对自杀（尤其是年轻人的自杀）非常关注，但对大学生酗酒与自杀之间关系的研究仍然有限。这项横断面研究调查了来自两个机构的大学生酗酒、自杀企图和自杀想法之间的关系。在来自公立大学的 2178 名参与者中，4.0% 的人表示有自杀企图，26.5% 的人表示有自杀念头。暴饮暴食与自杀企图或自杀念头没有显着关联。结果显示，女性（OR 1.62，95% CI：1.32-2.01；p  < 0.001）和酒精使用障碍（OR 2.23，95% CI：1.49-3.55；p  < 0.001）是自杀行为的独立预测变量。这些发现强调需要采取有针对性的干预措施来解决与酒精相关的行为和心理健康问题，特别是女性和患有酒精使用障碍的人，以提高大学生的整体心理健康。
