This study used multi-level analysis to estimate which type of factor explains most of the variance in alcohol consumption of Vietnamese students.
Data were collected among 6011 students attending 12 universities/faculties in four provinces in Vietnam. The three most recent drinking occasions were investigated per student, resulting in 12,795 drinking occasions among 4265 drinkers. Students reported on 10 aspects of the drinking context per drinking occasion. A multi-level mixed-effects linear regression model was constructed in which aspects of drinking context composed the first level; the age of students and four drinking motives comprised the second level. The dependent variable was the number of drinks.
Of the aspects of context, drinking duration had the strongest association with alcohol consumption while, at the individual level, coping motive had the strongest association. The drinking context characteristics explained more variance than the individual characteristics in alcohol intake per occasion.
These findings suggest that, among students in Vietnam, the drinking context explains a larger proportion of the variance in alcohol consumption than the drinking motives. Therefore, measures that reduce the availability of alcohol in specific drinking situations are an essential part of an effective prevention policy.
本研究采用多层次分析来估计哪种类型的因素能解释越南学生饮酒行为差异的大部分原因。
对越南四个省份12所大学/学院的6011名学生进行了数据收集。每位学生调查了最近的三次饮酒场合,4265名饮酒者共有12795次饮酒场合。学生们报告了每次饮酒场合饮酒环境的10个方面。构建了一个多层次混合效应线性回归模型,其中饮酒环境方面构成第一层次;学生年龄和四种饮酒动机构成第二层次。因变量是饮酒量。
在环境因素方面,饮酒持续时间与饮酒量的关联最强,而在个体层面,应对动机的关联最强。饮酒环境特征比个体特征更能解释每次饮酒时酒精摄入量的差异。
这些发现表明,在越南学生中,饮酒环境比饮酒动机更能解释饮酒行为差异的较大比例。因此,在特定饮酒情境中减少酒精供应的措施是有效预防政策的重要组成部分。
