Can vendors' age limit control measures increase compliance with the alcohol age limit? An evaluation of measures implemented by three Dutch liquor store chains.

BACKGROUND: Dutch liquor store (off license) chains have voluntarily developed and implemented age limit control measures to increase compliance with the Licensing and Catering Act (LCA), aimed at prohibiting vendors from selling alcohol to minors (<18 years old). This study investigates differences between three liquor store chains in their style of self-regulation and how that affects compliance with the LCA in four domains (capturing processes in age verification, instructing staff, monitoring performance/providing feedback and imposing consequences). METHODS: A mixed-method design was used. In depth-interviews (n = 3) were conducted with chains' head office managers, gaining insight into control measures. Survey (n = 372) research was conducted to measure liquor store owners' perceptions of implementation. Mystery shop (n = 387) research was conducted to measure compliance of store owners with the LCA. Survey and mystery shopping data was linked (n = 179) for the indicated perceived risk of inspection. RESULTS: The interviews indicated that control measures differ across chains in comprehensiveness and degree of implementation, survey results showed corresponding differences across the chains. Linked results showed that liquor store owners who perceive a very high risk of inspection, showed higher ID requesting rates (chain 2 and 3: 93% and 99%) and compliance rates (chain 2 and 3: 77% and 86%), respectively. This effect may be amplified by a set of measures (e.g., by implementing age verification systems, increasing training, monitoring performances and/or imposing consequences) and could result in higher ID request rates (chain 1: 54% versus chain 2 and 3: both 95%) and compliance rates (chain 1: 35% versus chain 2 and 3: both 80%). CONCLUSION: A comprehensive and systematic implementation of specific combinations of control measures in all four domains resulted in high compliance rates up to 80%. Nevertheless, the expectation is that this effect can only be attained when complemented by external government enforcement efforts.

Increased minimum legal age for the sale of alcohol in the Netherlands as of 2014: The effect on alcohol sellers' compliance after one and two years.

BACKGROUND: As of January 2014, the Dutch minimum legal age for the sale and purchase of all alcoholic beverages has increased from 16 to 18 years of age. The effectiveness of a minimum legal age policy in controlling the availability of alcohol for adolescents depends on the extent to which this minimum legal age is complied with in the field. The main aim of the current study is to investigate, for a country with a West-European drinking culture, whether raising the minimum legal age for the sale of alcohol has influenced compliance rates among Dutch alcohol vendors. METHODS: A total of 1770 alcohol purchase attempts by 15-year-old mystery shoppers were conducted in three independent Dutch representative samples of on- and off-premise alcohol outlets in 2013 (T0), 2014 (T1), and 2016 (T2). The effect of the policy change was estimated controlling for gender and age of the vendor. RESULTS: Mean alcohol sellers' compliance rates significantly increased for 15-year-olds from 46.5% before to 55.7% one year and to 73.9% two years after the policy change. Two years after the policy change, alcohol vendors were up to 3 times more likely to comply with the alcohol age limit policy. CONCLUSION: After the policy change, mean alcohol compliance rates significantly increased when 15-year-olds attempted to purchase alcohol, an effect which seems to increase over time. Nevertheless, a rise in the compliance rate was already present in the years preceding the introduction of the new minimum legal age. This perhaps signifies a process in which a lowering in the general acceptability of juvenile drinking already started before the increased minimum legal age was introduced and alcohol vendors might have been anticipating this formal legal change.

Alcohol and Tobacco Sales to Underage Buyers in Dutch Supermarkets: Can the Use of Age Verification Systems Increase Seller's Compliance?

PURPOSE: Age limits are effective in reducing alcohol- and tobacco-related harm, however, their effectiveness depends on the extent to which they are complied with. This study aimed to investigate the effectiveness of different age verification systems (AVSs) implemented by 400 Dutch supermarkets on requesting a valid age verification (ID) and on sellers' compliance. METHODS: A mixed method design was used. Compliance was measured by 800 alcohol and tobacco purchase attempts by 17-year-old mystery shoppers. To analyze the effectiveness of AVSs, logistic regression analyses were performed. Insight into facilitating and hindering factors in the purchase process was obtained by 13 interviews with supermarket managers. RESULTS: Only a tendency toward a positive effect of the presence of the keying-on-date-of-birth AVS or ID swiper/checker was found on ID request for both alcohol and tobacco purchase attempts. The use of the keying-on-date-of-birth AVS or ID swiper/checker significantly increased the odds for compliance after an ID was requested, for both alcohol and tobacco purchase attempts. Managers indicated that ID requests and compliance could be facilitated by providing cashiers with sufficient managerial support, technical support, and regular training about the purchase process and use of the AVS. CONCLUSIONS: The usage of AVSs calculating and confirming whether the customer reached the legal purchase age for cashiers significantly increases the odds for cashiers to comply with age limits of alcohol and tobacco. Future research should gain insight into how usage of effective AVSs can be improved and explore the feasibility of implementation and effectiveness in other outlets.

The effect of alcohol intake on cardiovascular disease and mortality disappeared after taking lifetime drinking and covariates into account.

BACKGROUND: Current alcohol intake has been associated with cardiovascular morbidity and mortality. The effect of past and lifetime drinking has received less attention. In the present study, the impact of current, past and lifetime drinking on cardiovascular events and all-cause mortality has been assessed. Secondly, the effect of accounting for covariates within these relationships has been studied. METHODS: The Lifestyle and Health study is a prospective cohort study in 2 regions of the Netherlands. Men and women aged 45 to 70 years registered in 34 general practices were followed over the period July 1996 to June 2001. At baseline, an extensive questionnaire had to be filled in. It included 3 questionnaires about alcohol intake: a Weekly Recall, a Quantity-Frequency about last year, and the Lifetime Drinking History questionnaire. Health problems were registered by the general practitioners. RESULTS: During follow-up, 679 men and 397 women had a cardiovascular event and 330 men and 204 women died. Current drinking was associated with lower risks of cardiovascular events (women) and all-cause mortality (men and women) compared with never drinkers. The relationships were strongest for alcohol intake measured with the Weekly Recall. Lifetime alcohol intake and alcohol intake in the distant past did not seem to be related to all-cause mortality or cardiovascular events. Adjustments for covariates weakened the relationships. CONCLUSIONS: Potential positive effects of drinking seem to be of a transient nature, as lifetime drinking and drinking in the past could not be related to all-cause mortality or cardiovascular events. The alleged benefits of current drinking at baseline diminished with increasing methodological quality and rigor.

Coping style mediates impact of stress on alcohol use: a prospective population-based study.

AIMS: This study examines the relationship between stressful life-events and alcohol use in a longitudinal cohort study, and investigates whether gender, coping style and social support modify this relationship. DESIGN, SETTING AND PARTICIPANTS: Data analysed in this paper come from a sample of 1608 men and 1645 women drawn randomly from the cohort known as the Dutch Lifestyle and Health Study, consisting of 16,210 men and women aged 45-70 years, who were followed-up for 4 years (1996-2000). MEASUREMENT: Alcohol use (recent and in the more distant past), occurrence of threatening life-events, coping style (action, cognitive and emotion coping), social support (perceived, actual support and social contacts) and other potential confounding factors were assessed with five annual self-administered questionnaires. The data were analysed with a mixed-effects modelling technique, controlling for interactions with time and gender. FINDINGS AND CONCLUSION: An interaction effect was found between experiencing a negative life-event and emotion coping on alcohol use. A positive relationship was found between the occurrence of negative life-events and alcohol use in subjects scoring high on emotion coping, and a negative one among subjects scoring low on emotion coping. Cognitive coping, action coping, actual support, social contacts and gender did not modify the relationship between life-events and alcohol use. However, having a more cognitive coping style or more social contacts was associated with a lower level of alcohol use, whereas having an action coping style and receiving more actual social support was associated with a higher drinking level. It seems plausible that people scoring high on emotion coping, characterized by a passive, resigned, indulgent and self-accusatory coping style, increase their alcohol use after experiencing a negative life-event.

A literature overview of the relationship between life-events and alcohol use in the general population.

AIMS: A critical review of the evidence of effects of stressful life-events on alcohol use in the general population, with a particular focus on study design. METHODS: A literature search in Medline was conducted, covering the period from 1990 to 2005, to identify articles in which the relationship between life-events and alcohol use in the general population (i.e. non-problem drinking population) was investigated. Samples with a limited age range (e.g. college students) were excluded. Twelve studies with a cross-sectional design, and four articles with a longitudinal design were included in this review. RESULTS: Four cross-sectional studies found evidence that experiencing life-events is related to higher alcohol use, three other studies, however, found no such association. The relationship between specific life-events and alcohol use in the five remaining cross-sectional studies is less clear-cut. Being a victim of crime was associated with higher alcohol use, but divorce and financial problems were related to both higher and lower alcohol use. Health-related life-events were found to be associated with lower alcohol use. In studies with a longitudinal design, it was found that health-related life-events and financial problems caused a decrease in alcohol use, and life-events related to spouse, friends and relatives, and retiring led to an increase in alcohol use. CONCLUSIONS: Evidence points towards a relationship between the occurrence of life-events and alcohol use in the general population. The direction of the effect is, however, not unequivocal. When life-events are operationalized or categorized separately they are not only related to an increased alcohol use but also to a decreased alcohol use. Specification of the model to be tested, including buffering factors such as gender, social support, coping resources, as well as baseline consumption, is important for a correct estimation of the effect of negative life-events.
