Epidemiology of Gambling Harm

Summary

Prevalence rates for problem or harmful gambling are estimated between 0.4% and 2.8% in the UK, with higher rates observed in online gambling compared to in-premise formats. While initial liberalisation led to increased participation and harm, rates have recently plateaued despite shifts in gambling habits.

Knowledge Gaps

• Lack of longitudinal data on how shifting gambling formats impact long-term population health outcomes.

Concerns

The disproportionate impact of gambling-related harms on marginalized and disadvantaged groups remains a critical public health concern.

Proposed Theories

• The 'Saturation Hypothesis' suggests that gambling prevalence plateaus as markets mature and regulatory frameworks tighten, regardless of total participation volume.
