Price discounting as a hidden risk factor of energy drink consumption.

ABSTRACT:

Objectives

Global consumption of caffeinated energy drinks (CED) has been increasing dramatically despite increasing evidence of their adverse health effects. Temporary price discounting is a rarely investigated but potentially powerful food marketing tactic influencing purchasing of CED. Using grocery transaction records generated by food stores in Montreal, we investigated the association between price discounting and purchasing of CED across socio-economic status operationalized by education and income levels in store neighbourhood.

Methods

The outcome, log-transformed weekly store-level sales of CED, was modelled as a function of store-level percent price discounting, store- and neighbourhood-level confounders, and an interaction term between discounting and each of tertile education and income in store neighbourhood. The model was separately fit to transactions from supermarkets, pharmacies, supercentres, and convenience stores.

Results

There were 18,743, 12,437, 3965, and 49,533 weeks of CED sales from supermarkets, pharmacies, supercentres, and convenience stores, respectively. Percent price discounting was positively associated with log sales of CED for all store types, and the interaction between education and discounting was prominent in supercentres: -0.039 [95% confidence interval (CI): -0.051, -0.028] and -0.039 [95% CI: -0.057, -0.021], for middle- and high-education neighbourhoods relative to low-education neighbourhoods, respectively. Relative to low-income areas, the associations of discounting and log CED sales in supercentres for neighbourhoods with middle- and high-income tertile were 0.022 [95% CI: 0.010, 0.033] and 0.015 (95% CI: -0.001, 0.031), respectively.

Conclusion

Price discounting is an important driver of CED consumption and has a varying impact across community education and income.

Project description:BackgroundThe purpose of this study was to identify how various negative health indicators are associated with energy drink consumption frequency among 13- and 15-year-old Finnish adolescents.MethodsData (N = 2429) from the nationally representative international Health Behaviour in School-aged Children study (2018) were analyzed via descriptive analysis and logistic regression analyses, with control for salient covariates. Relative risks (RR) were derived from the adjusted odds ratios.ResultsEven infrequent energy drink consumption was associated with various negative health indicators. Moreover, as compared to non-users, frequent energy drink consumers were more likely to report several health-compromising behaviors: current smoking (RR = 9.85, 95% CI: 5.68-16.02), current snus use (RR = 3.62, 95% CI: 1.80-6.85), cannabis use (RR = 3.42, 95% CI: 1.69-6.52), alcohol consumption (RR = 3.08, 95% CI: 2.49-3.71), problematic social media use (RR = 2.53, 95% CI:1.68-3.72), short sleep (RR = 2.12, 95% CI: 1.69-2.60), skipping breakfast (RR = 1.87, 95% CI: 1.51-2.29), drunkenness (RR = 1.59, 95% CI: 1.11-2.23), inadequate tooth brushing (RR = 1.28, 95% CI: 1.05-1.54). In addition, frequent energy drink consumption was associated with perceived negative health indicators: feelings of insufficient sleep (RR = 1.56, 95% CI: 1.11-2.15), low self-rated health (RR = 1.48, 95% CI: 1.15-1.87), and multiple health complaints (RR = 1.31, 95% CI: 1.07-1.56).ConclusionsEnergy drink consumption, even infrequent, was associated with several negative health indicators, and the reporting of these increased with the frequency of energy drink consumption. The findings support the concerns of health authorities regarding the negative associations between energy drink consumption and health, even among persons as young as 13 years. There is evidence to support specific policy level actions, including restrictions on the sale of energy drinks to adolescents. This measure has been proposed in a Finnish government program, but implementation has yet to occur. Moreover, marketing of these beverages in platforms that are popular among adolescents (e.g., the social media) should be rigorously evaluated, and comprehensive interventions and actions implemented to ensure that adolescents, parents/guardians, and professionals working with adolescents (e.g., in schools) have a good understanding of the links between energy drink consumption and health.

Project description:BackgroundFrequent consumption of Energy Drinks (EDs) is associated with numerous health problems, including overweight and obesity, particularly among children and adolescents. The extensive promotion, wide accessibility, and relatively low cost of EDs have significantly increased their popularity among this age group. This paper examines policies/programs that, directly and indirectly, contribute to reducing ED consumption in children and adolescents and shares global experiences to help policymakers adopt evidence-based policies.MethodsA systematic search was performed using PubMed, Scopus, and Web of Science databases from January 2000 to June 2024, along with reputable international organization websites, to find literature on policies aimed at reducing ED consumption among children and adolescents. All sources meeting the inclusion criteria were included without restrictions. Titles and abstracts were initially screened, followed by a full-text review. After evaluating the quality of the selected studies, data were extracted and, along with information from the selected documents, compiled into a table, detailing the country, policy type, and the effectiveness and weaknesses of each policy.ResultsOut of 12166 reviewed studies and documents, 84 studies and 70 documents met the inclusion criteria. 73 countries and territories have implemented policies like taxation, sales bans, school bans, labeling, and marketing restrictions on EDs. Most employ fiscal measures, reducing consumption despite enforcement challenges. Labeling, access restrictions, and marketing bans are common but face issues like black markets.ConclusionThis scoping review outlines diverse strategies adopted by countries to reduce ED consumption among children and teenagers, such as taxation, school bans, sales restrictions, and labeling requirements. While heightened awareness of ED harms has reinforced policy efforts, many Asian and African nations lack such measures, some policies remain outdated for over a decade, and existing policies face several challenges. These challenges encompass industry resistance, governmental disagreements, public opposition, economic considerations, and the intricacies of policy design. Considering this, countries should tailor policies to their cultural and social contexts, taking into account each policy's strengths and weaknesses to avoid loopholes. Inter-sectoral cooperation, ongoing policy monitoring, updates, and public education campaigns are essential to raise awareness and ensure effective implementation.
