BACKGROUND
Binge drinking (BD) seems to be related to health and social complications among adolescents. Considering that knowledge about BD in developing countries is limited and that in Brazil high socioeconomic status is a risk factor for alcohol abuse, this study sheds light about this phenomenon among adolescents from a different cultural background than prior North-American and European studies.
METHODS
Brazilian students (n = 2691) selected through a representative, stratified and clustered sampling method were asked to answer a self-report questionnaire. The questionnaire contained questions about patterns of alcohol consumption, religious beliefs, leisure activities, family structure and relationships. Data were analyzed with basic contingency tables with Chi-square tests followed by a decision tree analysis and weighted logistic regression.
RESULTS
Almost thirty-five percent of the students reported recent binge drinking. BD in the past month was positively associated with older age (aOR = 1.5[1.2-1.7]), male gender (aOR = 1.5[1.2-2.0]) going out with friends almost every night (aOR = 33.9[14.2-80.7]), not living with mother (aOR = 2.4[1.3-4.7]), believing in God with little conviction (aOR = 1.6[1.2-2.0]) and rarely talking to parents about anything (aOR = 1.7[1.3-2.2]) or always about drugs (aOR = 1.8[1.3-2.5]). Factors inversely associated with BD were: paying lower monthly tuition fees (aOR = 0.5[0.4-0.9]), living with people who do not get drunk (aOR = 0.6[0.4-0.7]) and frequent engagement in worships (aOR = 0.7[0.5-0.9]).
CONCLUSION
The habit of BD in adolescents enrolled in private high schools in Brazil is strongly linked to the frequency with which they go out with friends at night. Factors such as religiosity, expressed by trust in God and participation in worship, and being enrolled in a school with cheaper tuition fees were associated with avoidance of BD in this population.
背景
狂饮（BD）似乎与青少年的健康和社会并发症有关。考虑到发展中国家对 BD 的了解有限，而在巴西，高社会经济地位是酗酒的一个风险因素，因此，与之前在北美和欧洲进行的研究相比，这项研究从不同的文化背景揭示了青少年中的这一现象。
方法
通过具有代表性、分层和聚类抽样方法选择的巴西学生（n=2691）被要求回答一份自我报告问卷。问卷包含关于饮酒模式、宗教信仰、休闲活动、家庭结构和关系的问题。使用基本列联表进行数据分析，并进行卡方检验，然后进行决策树分析和加权逻辑回归。
结果
近 35%的学生报告最近有过狂饮。过去一个月的 BD 与年龄较大（优势比[OR]=1.5[1.2-1.7]）、男性（OR=1.5[1.2-2.0]）、几乎每晚与朋友外出（OR=33.9[14.2-80.7]）、与母亲不住在一起（OR=2.4[1.3-4.7]）、对上帝的信仰不太坚定（OR=1.6[1.2-2.0]）、很少与父母谈论任何事情（OR=1.7[1.3-2.2]）或总是谈论毒品（OR=1.8[1.3-2.5]）呈正相关。与 BD 呈负相关的因素包括：支付较低的月学费（OR=0.5[0.4-0.9]）、与不醉酒的人生活在一起（OR=0.6[0.4-0.7]）和经常参加礼拜（OR=0.7[0.5-0.9]）。
结论
巴西私立高中学生的 BD 习惯与他们夜间与朋友外出的频率密切相关。宗教信仰等因素，如对上帝的信任和参与礼拜，以及就读学费较低的学校，与该人群避免 BD 有关。
