What the Global Gambling Boom Means for Public Health

by Jon Scaccia August 7, 2024

The world of gambling has seen explosive growth in recent years, with projections suggesting that the global gambling yield will soar to $531 billion by 2025. This meteoric rise is not just a financial phenomenon but a burgeoning public health issue. As gambling becomes more pervasive, the need to understand its impacts on society has never been more critical.

The Expanding Universe of Gambling

Gambling, in its myriad forms, is becoming an integral part of everyday life. From traditional casinos and lotteries to the rapidly growing realm of online gambling, people have more opportunities to gamble than ever before. This widespread availability is not without consequences. The World Health Organization (WHO) first recognized excessive gambling as a health issue in 1977. Since then, the Diagnostic and Statistical Manual of Mental Disorders (DSM) has included criteria for diagnosing gambling disorders.

A persistent pattern of gambling behaviors defines these disorders despite significant distress or impairment in personal, social, or occupational functioning. The consequences of gambling can be severe, impacting individuals’ financial stability, physical health, relationships, mental well-being, employment, and education.

A Closer Look at Gambling Prevalence

Previous studies have painted a mixed picture of gambling prevalence, particularly among adults and adolescents. These studies often focused on “problem gambling”—gambling behavior that disrupts personal and professional lives. However, there’s more to the story. The spectrum of gambling severity ranges from mild issues with few consequences to severe gambling disorders characterized by a loss of control and extensive negative impacts.

A comprehensive review and meta-analysis conducted on studies from 2010 onwards sought to update and expand our understanding of gambling prevalence worldwide. This review synthesized data from 380 unique samples representing over 3.4 million individuals across 68 countries.

Key Findings: A Global Snapshot

The review revealed that 46.2% of adults and 17.9% of adolescents have gambled in the past 12 months. This equates to roughly 2.3 billion adults and 159.6 million adolescents globally. These figures underscore the widespread nature of gambling and the potential for associated harms.

The study also found significant regional differences. For example, Australasia had the highest prevalence of adult gambling at 70%, while Latin America had the lowest at 31.7%. North America and Western Europe also showed high rates of gambling participation.

The Risks and Harms of Gambling

One of the most striking findings of the review was the prevalence of “any risk gambling,” a term that includes both problem gambling and milder forms of gambling that still result in negative consequences. Approximately 8.7% of adults and a notable proportion of adolescents engage in any risk gambling. This translates to nearly 440 million adults worldwide.

Problematic gambling, a more severe form, affects 1.4% of adults globally, or about 71.7 million people. The study highlighted that certain gambling activities carry higher risks. Online casinos, for instance, have a higher prevalence of problematic gambling compared to traditional forms like lotteries.

Why This Matters for Public Health

The rapid expansion of gambling, especially online gambling, poses significant challenges for public health. Online gambling is particularly concerning due to its accessibility and the potential for anonymous and continuous play. The COVID-19 pandemic has likely exacerbated this trend, with many turning to online platforms for entertainment during lockdowns.

Public health practitioners and researchers must pay close attention to these trends. The harms associated with gambling extend beyond individual health, affecting families, communities, and society at large. Financial stress, mental health issues, and strained relationships are just a few of the ripple effects.

Moving Forward: Policy and Prevention

Addressing the public health impact of gambling requires a multifaceted approach. Governments and public health organizations need to implement policies that regulate the availability and marketing of gambling, especially online gambling. Education and awareness campaigns can help inform the public about the risks associated with gambling and promote healthier behaviors.

Moreover, support systems for individuals struggling with gambling disorders are crucial. Counseling, helplines, and community support groups can provide much-needed assistance to those affected.
