The effectiveness of school alcohol polices may be affected by the degree of strictness of rules, how they are implemented and enforced, students' perception of the rules and the consequences of breaking them. The aim of the study was to test the hypothesis that more liberal school alcohol policies, lack of knowledge of the alcohol policy, lower prices of alcohol at school parties, and liberal party regulation were associated with more drinking among high school students.
Participants were high school students (n = 68,898), participating in the Danish National Youth Study in 2014. Data came from questionnaires answered by high school students and school headmasters. Zero-inflated negative binominal regression with clustering of schools (n = 117) was used to assess the associations between alcohol policy reported by school headmaster and weekly alcohol intake reported by students. Multilevel negative binominal regression was used to assess the associations between alcohol price and liberal party regulations and units consumed at the last school party and units consumed at the school during the last school party.
In general, school alcohol policies were not associated with high school students' weekly alcohol intake. High school students who did not know the school alcohol policy had a higher weekly alcohol intake (0.16 drinks 95% CL [0.11;0.21] p = 0.000), compared to students who knew the policy. Lower beer prices were positively associated with the number of drinks consumed at the school (p = 0.004), but not with the total amount consumed at the last school party (p = 0.728). High school students who agreed that students who were drunk could buy alcohol had a higher alcohol intake at the last school party (OR = 0.20 drinks 95% CL [0.18;0.21], p < 0.001) and drank more at the school (0.17 drinks 95% CL [0.15;0.18], p < 0.001) compared to those who did not agree that students who were drunk could buy alcohol.
School alcohol policies were generally not associated with drinking among high school students, whereas students' lack of knowledge of the school policy was associated with a higher weekly alcohol intake. An addition, lower prices and liberal party regulation was associated with higher alcohol intake at school parties.
学校的酒精政策的有效性可能受到规则的严格程度、规则的实施和执行情况、学生对规则的看法以及违反规则的后果的影响。本研究的目的是检验以下假设,即更宽松的学校酒精政策、缺乏对酒精政策的了解、学校派对上的酒精价格更低、以及宽松的政党监管与高中生饮酒更多有关。
参与者为高中生(n=68898),于 2014 年参加丹麦全国青年研究。数据来自高中生和中学校长回答的问卷。采用零膨胀负二项式回归,对学校校长报告的酒精政策与学生报告的每周饮酒量进行聚类(n=117)。采用多层次负二项式回归,评估学校派对上最后一次饮酒和学校派对期间饮酒的酒精价格和宽松政党法规的关联。
总体而言,学校的酒精政策与高中生的每周饮酒量无关。不知道学校酒精政策的高中生每周饮酒量较高(0.16 杯,95%置信区间[0.11;0.21],p=0.000),与知道政策的学生相比。啤酒价格较低与在校饮酒量呈正相关(p=0.004),但与最后一次学校派对的总饮酒量无关(p=0.728)。同意醉酒学生可以购买酒精的高中生在最后一次学校派对上饮酒量较高(OR=0.20 杯,95%置信区间[0.18;0.21],p<0.001),在校饮酒量也较高(0.17 杯,95%置信区间[0.15;0.18],p<0.001),与不同意醉酒学生可以购买酒精的学生相比。
学校的酒精政策总体上与高中生饮酒无关,而学生对学校政策的不了解与每周饮酒量增加有关。此外,较低的价格和宽松的政党监管与学校派对上的更高酒精摄入量有关。
