Evaluation of a Mystery Shopper Intervention to Reduce Sales of Alcohol to Minors in Zacatecas and Guadalupe, Mexico

A monitoring and site visit intervention to reduce sales to minors at packaged liquor outlets

ISSUE ADDRESSED

Selling alcohol to a minor is a serious offence in the New South Wales Liquor Act. However, minors report they can purchase alcohol easily. This study used an intersectoral partnership between the Central Coast Local Health District (CCLHD) Health Promotion Service, and Liquor & Gaming NSW (L&GNSW) Compliance Operations to test a site visit intervention to increase ID checks at packaged liquor outlets (PLOs).

METHODS

As the current legislative framework does not allow minors to attempt to purchase alcohol from PLOs, even under compliance operations, this study employed pseudo-minors aged 18-19 years. Pseudo-minors visited all PLOs on the Central Coast, NSW in four survey rounds, attempting to purchase alcohol without ID. If a PLO sold alcohol to the pseudo-minor, they received a visit from a Health Promotion Officer and L&GNSW Inspector to inform them of the sale and that they are at risk of selling alcohol to a minor.

RESULTS

Site visits were an effective intervention to increase the rates of ID checking. Alcohol sales to pseudo-minors without ID decreased from 34% in Round 1 to 7% in Round 4. Young sales staff and independent stores were less likely to check ID.

CONCLUSIONS

This intervention was associated with some of the lowest rates of underage alcohol purchasing reported to date. However, it may not be sustainable in the long term. It is recommended that: future studies randomise site visits to investigate their contribution to the observed reduction, cost effectiveness of the intervention is explored and legislative change to allow controlled purchase operations for alcohol is considered. SO WHAT?: Young people under 18 years of age should not be able to purchase alcohol from liquor licence outlets, and strong laws apply if a sale is detected. However, despite these rules, young people still report they can access alcohol in this manner. Whilst our intervention of site visits with the regulatory body saw decreases in sales to our pseudo-minors, we advocate for controlled purchase operations (similar to tobacco control) as a more sustainable and effective intervention to reduce sales to minors - while this is not yet legislated for packaged liquor outlets in Australia, it is deemed best practice in other countries.

Association of service facilities and amenities with adolescent birth rates in Mexican cities

BACKGROUND

The association of the built environment and the structural availability of services/amenities with adolescent birth rates (ABR) has been overlooked in Latin America. We investigated the association of the availability, and changes in the availability, of services/amenities with ABR in 92 Mexican cities.

METHODS

We estimated ABR using data on live birth registration linked to municipality of residence at the time of birth from 2008-2017. The number of services/amenities were obtained from the National Statistical Directory of Economic Units in 2010, 2015, and 2020 and grouped as follows: education, health care, pharmacies, recreation, and on- and off-premises alcohol outlets. Data were linearly interpolated to obtain yearly estimates. We estimated densities per square km by municipality. We fitted negative binomial hybrid models, including a random intercept for municipality and city, and adjusted for other social environment variables.

RESULTS

After adjustment a 1-unit increase in the density of recreation facilities, pharmacies, and off-premises alcohol outlets within municipalities was associated with a 5%, 4% and 12% decrease in ABR, respectively. Municipalities with higher density of education, recreational and health care facilities had a lower ABR; in contrast, municipalities with a higher density of on-premises alcohol experienced a higher ABR.

CONCLUSION

Our findings highlight the importance of economic drivers and the need to invest in infrastructure, such as pharmacies, medical facilities, schools, and recreation areas and limit the availability of alcohol outlets to increase the impact of current adolescent pregnancy prevention programs.
