尽管能量饮料与自杀之间存在关联，但此前很少有研究考虑包括压力、睡眠和学业表现在内的情绪因素在青少年中的作用。这项研究的目的是评估能量饮料与自杀的关联，而不考虑可能的混杂因素，包括压力、睡眠和学校表现。2014年和2015年韩国青少年危险行为网络调查共对121,106名13-18岁的青少年进行了年龄、性别、居住地区、经济水平、父母和母亲的教育水平、睡眠时间、压力水平、学习表现、能量饮料摄入频率和自杀企图的调查。主观压力水平分为重度、中度、轻度、轻微和无压力。睡眠时间分为6组：6h；6≤h<；7；7≤h<；8；8≤h<；9；≥9h。学习成绩分为A(最高)、B(中、高)、C(中)、D(中、低)和E(最低)5个水平。能量饮料的饮用频率分为3组：每周≥3次、1~2次和0次。采用多重Logistic回归分析和有序Logistic回归分析，分析睡眠时间、压力水平和学业成绩与自杀未遂和能量饮料摄入量之间的关系。采用复合抽样多元Logistic回归分析能量饮料摄入频率与自杀未遂之间的关系。较高的压力水平、缺乏睡眠和较低的学业成绩与自杀企图显著相关(P<；0.001)。高压力水平、异常睡眠时间和低学习成绩等变量也与较高的能量饮料摄入量成比例相关(P<；0.001)。多因素Logistic回归分析显示，能量饮料摄入频度与自杀企图显著相关(每周摄入能量饮料3次的≥比值比=3.0 3，95%CI=2.64~3.49，P<；0.001)。在韩国青少年中，严重的压力、睡眠不足和低学习成绩与摄入更多能量饮料和自杀企图有关。频繁摄入能量饮料与自杀企图呈正相关，即使在调整了压力、睡眠时间和学校表现后也是如此。
Although an association between energy drinks and suicide has been suggested, few prior studies have considered the role of emotional factors including stress, sleep, and school performance in adolescents. This study aimed to evaluate the association of energy drinks with suicide, independent of possible confounders including stress, sleep, and school performance. In total, 121,106 adolescents with 13–18 years olds from the 2014 and 2015 Korea Youth Risk Behavior Web-based Survey were surveyed for age, sex, region of residence, economic level, paternal and maternal education level, sleep time, stress level, school performance, frequency of energy drink intake, and suicide attempts. Subjective stress levels were classified into severe, moderate, mild, a little, and no stress. Sleep time was divided into 6 groups: < 6 h; 6 ≤ h < 7; 7 ≤ h < 8; 8 ≤ h < 9; and ≥ 9 h. School performance was classified into 5 levels: A (highest), B (middle, high), C (middle), D (middle, low), and E (lowest). Frequency of energy drink consumption was divided into 3 groups: ≥ 3, 1–2, and 0 times a week. The associations of sleep time, stress level, and school performance with suicide attempts and the frequency of energy drink intake were analyzed using multiple and ordinal logistic regression analysis, respectively, with complex sampling. The relationship between frequency of energy drink intake and suicide attempts was analyzed using multiple logistic regression analysis with complex sampling. Higher stress levels, lack of sleep, and low school performance were significantly associated with suicide attempts (each P < 0.001). These variables of high stress level, abnormal sleep time, and low school performance were also proportionally related with higher energy drink intake (P < 0.001). Frequent energy drink intake was significantly associated with suicide attempts in multiple logistic regression analyses (AOR for frequency of energy intake ≥ 3 times a week = 3.03, 95% CI = 2.64–3.49, P < 0.001). Severe stress, inadequate sleep, and low school performance were related with more energy drink intake and suicide attempts in Korean adolescents. Frequent energy drink intake was positively related with suicide attempts, even after adjusting for stress, sleep time, and school performance.
