AIM: To present a comparison between the effects on health due to a reduction in binge drinking (BD) and health-related quality of life (HRQoL), as a result of ALERTA ALCOHOL, an intervention aimed at reducing BD in Spanish adolescents.

METHODS: A two-arm cluster randomized controlled trial was conducted with an intervention and a control group, randomized at the school level, following individuals over four months. The study population consisted of Andalusian adolescents aged 15 to 19 years who were enrolled in urban public high schools (n=1247). Participants were assigned randomly to receive the intervention. The main outcomes studied were the number of occasions of BD in the last 30 days, which was directly obtained from the answers given by the adolescents, and HRQoL measured with the EQ-5D-5L questionnaire. The model of estimation was the generalized estimating equations (GEE) approach.

RESULTS: The program showed a BD reduction at the 4-month follow-up, although it was not shown to significantly increase the HRQoL in adolescents who reduced the number of occasions of BD and had received the intervention. However, it was shown that those who would predictably reduce the number of occasions of BD controlled by several sociodemographic variables perceived a higher HRQoL, as did those who had a greater adherence to the program.

CONCLUSIONS: Higher adherence to a web-based computer-tailored intervention to prevent BD in adolescents has a positive effect on decreasing the number of occasions of BD in adolescents as well as on increasing participants' HRQoL, although this second effect is very small, which could be due to the short follow-up time. This fact is quite important and should be assessed extensively to corroborate the results and translate into health policy.

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 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.

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.
