中学生自杀行为与能量饮料饮用的关系
Relationship between Suicidal Behavior and Energy Drink Consumption of Middle School Students

目的：调查中学生自杀行为现状及与能量饮料饮用的关系，为开展中学生自杀干预提供参考。方法：采用分层整群随机抽样，在重庆市某区选取中学生3903人完成问卷调查。结果：46.1%中学生有自杀行为；不同学段、生源地、性别、吸烟、饮酒、能量饮料饮用情况学生“无自杀行为”比例差异显著(2值分别为40.081、11.973、27.741、18.319、36.904、67.265，均P < 0.01)。32.6%中学生饮用能量饮料，不同学校、学段、性别、饮酒情况学生能量饮料饮用率差异显著(2值分别为10.679、109.411、49.994、5.385，均P < 0.01)。能量饮料饮用是中学生自杀行为的影响因素，不喝能量饮料是“自杀意念”(OR = 0.656, 95%CI = 0.563~0.764)、“自杀计划”(OR = 0.500, 95%CI = 0.396~0.631)、“自杀尝试”(OR = 0.695, 95%CI = 0.468~1.031)的保护因素。结论：近一半中学生有自杀相关行为；饮用能量饮料的中学生更易出现自杀行为，应引导中学生不喝或少喝能量饮料。
Objective: To investigate relationship between suicidal behavior and energy drinkconsumption of middle school students, and provide suggestions for suicidal intervention. Methods: Using stratified random cluster sampling and selected 3903 middle school students to complete questionnaires in Chongqing. Results: 46.1% middle school students had suicidal behavior; there were significant differences between different middle school stage, native place, gender, smoking, drinking alcohol, drinking energy drink students’ non-sucidical behaviors’ rates (2 were 40.081, 11.973, 27.741, 18.319, 36.904, 67.265 respectively, both P < 0.01). 32.6% middle school students had drunk energy drink, there were significant differences between different school, middle school stage, gender, drinking alcohol students’ energy drink consumption rates (2 were 10.679, 109.411, 49.994, 5.385 respectively, both P < 0.01). Energy drink consumption could influence middle school students’ suicidal behavior, “no energy drink consumption” was the protective factor of suicidal ideation (OR = 0.656, 95%CI = 0.563~0.764), planned suicide (OR = 0.500, 95%CI = 0.396~0.631) and attempted suicide (OR = 0.695, 95%CI = 0.468~1.031). Conclusion: Nearly 50% middle school students had suicidal behavior; the students who have energy drink consumption are more likely to have suicidal behavior, so they should be guided not to drink or less drink energy drinks.
