Effectiveness of Workplace Intervention for Reducing Alcohol Consumption: a Systematic Review and Meta-Analysis

AIMS: To review the effectiveness of workplace interventions in reducing alcohol consumption among employees.

METHODS: 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 CochraneCochrane is a global independent network of health practitioners researchers patient advocates and o... risk of bias tool.

RESULTS: 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.

CONCLUSION: 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.
