Introduction

The negative effects of alcohol consumption on learning ability and intellectual development of youth may be recovered after cessation. This study explored to what extent reduction or complete cessation of alcohol consumption affects school performance of secondary school students.

Methods

Alcohol use was self-reported by 37,223 grade 9–12 students attending 89 secondary schools across Ontario (n = 79) and Alberta (n = 10), Canada, participating in the COMPASS study over four years (school years 2013–14 to 2016–17). Measures included past-year frequency of drinking and frequency of binge drinking. A first-order autoregressive multinomial logistic regression was used to establish the impact of reduction or cessation of alcohol use on school performance.

Results

During follow-up, 1465 (6.4%) reductions and 1903 (8.3%) cessations in alcohol consumption, and 1447 (10.1%) reductions and 2147 (14.9%) cessations of binge drinking were reported. Male students reported more cessation in both drinking (9.7% male vs 7.1% female) and binge drinking (15.6% male vs 14.4% female), though female students had higher rates of reductions. Students who quit or reduced their drinking or binge drinking were less likely to skip classes, leave their homework incomplete, or expect to get or to aspire to educational qualifications above a high school diploma compared to those who continued their alcohol use.

Conclusions

Aside from health benefits, reduction or cessation of alcohol use may improve students’ academic rigor. Prioritising school-based alcohol prevention efforts may therefore be beneficial for aspects of academic performance.

对加拿大中学生样本中戒酒和学习成绩的纵向检查

介绍

戒酒后可能会恢复饮酒对青少年学习能力和智力发展的负面影响。这项研究探讨了减少或完全停止饮酒对中学生的学业表现有多大影响。

方法

在加拿大安大略省（n = 79）和加拿大艾伯塔省（n = 10）的89所中学中，有37,223名9-12岁的学生自我报告了酒精使用情况，并参加了四年的COMPASS研究（2013-14至2016学年） –17）。措施包括过去一年的饮酒频率和暴饮酒频率。一阶自回归多项式逻辑回归用于确定减少或停止饮酒对学校成绩的影响。

结果

在随访期间，据报告减少了1465（6.4％）的饮酒量和1903（8.3％）的饮酒量减少，减少了1447（10.1％）的饮酒量和2147（14.9％）的饮酒量的减少。男学生报告戒酒（男性分别为9.7％和7.1％）和暴饮暴食（男性为15.6％，女性为14.4％）的戒烟率更高，尽管女学生的戒烟率更高。与继续饮酒的学生相比，戒酒或减少饮酒或暴饮暴食的学生不太可能跳过课程，完成功课，或者期望获得或渴望获得高中文凭以上的学历。

结论

除了对健康有益之外，减少或停止饮酒可能会提高学生的学业严谨性。因此，优先考虑基于学校的饮酒预防工作可能对学习成绩有所帮助。
