A systematic review of alcohol education programs for young people: do these programs change behavior?

Comparison of emergency transport for acute alcohol intoxication before and after the coronavirus disease 2019 pandemic: A retrospective observational study

The ongoing coronavirus disease 2019 (COVID-19) pandemic has had a broad effect on social, economic, educational, and political systems. We investigated the effect of COVID-19 on emergency transportation due to acute alcohol intoxication in the Kochi Prefecture in Japan, a region with high alcohol consumption. This retrospective observational study was conducted using the data of 62,138 patients from the Kochi-Iryo-Net database, Kochi Prefecture's emergency medical and wide-area disaster information system. Chi-square tests and multiple logistic regression analyses were performed to examine the association between emergency transportation and alcohol intoxication. This analysis compared the monthly number of transportations during 2019 (as reference) with that throughout 2020 and 2021. Approximately 1.5 % of all emergency transportation cases were related to acute alcohol intoxication. The number of emergency transportation cases due to acute alcohol intoxication declined by 0.5 % in 2020 and 0.7 % in 2021 compared with that in 2019. Moreover, compared with that in 2019, the number of cases of emergency transportation due to acute alcohol intoxication significantly decreased in 2020 (incidence rate ratio: 0.78; 95 % confidence interval: 0.67-0.91) and 2021 (incidence rate ratio: 0.73; 95 % confidence interval: 0.63-0.86). Lifestyle changes due to the COVID-19 pandemic affected the number of emergency transports due to acute alcohol intoxication in 2020 and 2021 (during the COVID-19 pandemic) compared to that in 2019 (before the pandemic).

Digital interventions to moderate alcohol consumption in young people: a Cancer Prevention Europe overview of systematic reviews

Background

Strategies to reduce alcohol consumption would contribute to substantial health benefits in the population, including reducing cancer risk. The increasing accessibility and applicability of digital technologies make these powerful tools suitable to facilitate changes in behaviour in young people which could then translate into both immediate and long-term improvements to public health.

Objective

We conducted a review of systematic reviews to assess the available evidence on digital interventions aimed at reducing alcohol consumption in sub-populations of young people [school-aged children, college/university students, young adults only (over 18 years) and both adolescent and young adults (<25 years)].

Methods

Searches were conducted across relevant databases including KSR Evidence, Cochrane Database of Systematic Reviews (CDSR) and Database of Abstracts of Reviews of Effects (DARE). Records were independently screened by title and abstract and those that met inclusion criteria were obtained for full text screening by two reviewers. Risk of bias (RoB) was assessed with the ROBIS checklist. We employed a narrative analysis.

Results

Twenty-seven systematic reviews were included that addressed relevant interventions in one or more of the sub-populations, but those reviews were mostly assessed as low quality. Definitions of "digital intervention" greatly varied across systematic reviews. Available evidence was limited both by sub-population and type of intervention. No reviews reported cancer incidence or influence on cancer related outcomes. In school-aged children eHealth multiple health behaviour change interventions delivered through a variety of digital methods were not effective in preventing or reducing alcohol consumption with no effect on the prevalence of alcohol use [Odds Ratio (OR) = 1.13, 95% CI: 0.95-1.36, review rated low RoB, minimal heterogeneity]. While in adolescents and/or young adults who were identified as risky drinkers, the use of computer or mobile device-based interventions resulted in reduced alcohol consumption when comparing the digital intervention with no/minimal intervention (-13.4 g/week, 95% CI: -19.3 to -7.6, review rated low RoB, moderate to substantial heterogeneity).In University/College students, a range of E-interventions reduced the number of drinks consumed per week compared to assessment only controls although the overall effect was small [standardised mean difference (SMD): -0.15, 95% CI: -0.21 to -0.09]. Web-based personalised feedback interventions demonstrated a small to medium effect on alcohol consumption (SMD: -0.19, 95% CI: -0.27 to -0.11) (review rated high RoB, minimal heterogeneity). In risky drinkers, stand-alone Computerized interventions reduced short (SMD: -0.17, 95% CI: -0.27 to -0.08) and long term (SMD: -0.17, 95% CI: -0.30 to -0.04) alcohol consumption compared to no intervention, while a small effect (SMD: -0.15, 95% CI: -0.25 to -0.06) in favour of computerised assessment and feedback vs. assessment only was observed. No short-term (SMD: -0.10, 95% CI: -0.30 to 0.11) or long-term effect (SMD: -0.11, 95% CI: -0.53 to 0.32) was demonstrated for computerised brief interventions when compared to counsellor based interventions (review rated low RoB, minimal to considerable heterogeneity). In young adults and adolescents, SMS-based interventions did not significantly reduce the quantity of drinks per occasion from baseline (SMD: 0.28, 95% CI: -0.02 to 0.58) or the average number of standard glasses per week (SMD: -0.05, 95% CI: -0.15 to 0.05) but increased the risk of binge drinking episodes (OR = 2.45, 95% CI: 1.32-4.53, review rated high RoB; minimal to substantial heterogeneity). For all results, interpretation has limitations in terms of risk of bias and heterogeneity.

Conclusions

Limited evidence suggests some potential for digital interventions, particularly those with feedback, in reducing alcohol consumption in certain sub-populations of younger people. However, this effect is often small, inconsistent or diminishes when only methodologically robust evidence is considered. There is no systematic review evidence that digital interventions reduce cancer incidence through alcohol moderation in young people. To reduce alcohol consumption, a major cancer risk factor, further methodologically robust research is warranted to explore the full potential of digital interventions and to form the basis of evidence based public health initiatives.

Acute effect of the COVID-19 pandemic on emergency transportation due to acute alcoholic intoxication: a retrospective observational study

Background

The COVID-19 pandemic has caused changes in people’s drinking habits and the emergency management system for various diseases. However, no studies have investigated the pandemic’s impact on emergency transportation for acute alcoholic intoxication. This study examines the effect of the pandemic on emergency transportation due to acute alcoholic intoxication in Kochi Prefecture, Japan, a region with high alcohol consumption.

Methods

A retrospective observational study was conducted using data of 180,747 patients from the Kochi-Iryo-Net database, Kochi Prefecture’s emergency medical and wide-area disaster information system. Chi-squared tests and multiple logistic regression analyses were performed. The association between emergency transportation and alcoholic intoxication was examined. The differences between the number of transportations during the voluntary isolation period in Japan (March and April 2020) and the same period for 2016–2019 were measured.

Results

In 2020, emergency transportations due to acute alcoholic intoxication declined by 0.2%, compared with previous years. Emergency transportation due to acute alcoholic intoxication decreased significantly between March and April 2020, compared with the same period in 2016–2019, even after adjusting for confounding factors (adjusted odds ratio 0.67; 95% confidence interval 0.47–0.96).

Conclusions

This study showed that lifestyle changes due to the COVID-19 pandemic affected the number of emergency transportations; in particular, those due to acute alcoholic intoxication decreased significantly.
