To review the effectiveness of workplace interventions in reducing alcohol consumption among employees.
Systematic search of science databases from inception till May 2018 for trials where an intervention was tested against a control and data presented as amount of alcohol consumed per week. Quality of trials was assessed by Cochrane risk of bias tool. Meta-analysis was performed with random-effects model and pooled mean difference (MD) was reported with 95% confidence interval. Publication bias was assessed using Egger's test.
Seven trials with 1291 participants could be included. No outcome assessments were blinded. There was positive effect of workplace intervention on reduction of alcohol consumption with pooled MD of -2.25 [95% CI: -4.20 to -0.30]. The effect was only seen where subjects had a baseline alcohol consumption of over 15 standard drinks per week. There was no heterogeneity across the trials (I2=0%). Funnel plot was symmetrical shaped and Egger's test confirmed that there was no publication bias. Two studies found no advantages to intervention on differences on the AUDIT test.
There is weak evidence for workplace interventions (varying modes) as a way of facilitating reduction in the consumption of alcohol among employees but only among the heavier consumers.
综述工作场所干预措施在减少员工饮酒量方面的有效性。
系统检索从创建到 2018 年 5 月的科学数据库中的试验，其中干预措施与对照组进行了测试，并以每周饮酒量呈现数据。通过 Cochrane 偏倚风险工具评估试验质量。采用随机效应模型进行荟萃分析，并报告具有 95%置信区间的合并均数差（MD）。使用 Egger 检验评估发表偏倚。
纳入了 7 项试验，共 1291 名参与者。没有对结果评估进行盲法。工作场所干预措施对减少饮酒量有积极影响，合并 MD 为-2.25 [95% CI：-4.20 至-0.30]。这种效果仅在受试者每周饮酒超过 15 标准杯时才出现。试验之间没有异质性（I2=0%）。漏斗图呈对称形状，Egger 检验证实没有发表偏倚。两项研究发现，干预措施在 AUDIT 测试上的差异没有优势。
有弱证据表明工作场所干预措施（不同模式）可作为促进员工饮酒量减少的一种方法，但仅对饮酒量较高的人群有效。
