Gambling Disorder Diagnoses Show Marked Increase in States With Legal Sports Betting

Researchers who examined U.S. electronic health records identified a rise exceeding 60 percent in gambling disorder diagnoses since 2018 within states that legalized sports betting, and the most pronounced growth appeared among young men. The rate moved from 3.0 cases per 100,000 people to 4.8 cases per 100,000 during the same period, while legal sports betting continued its expansion across additional jurisdictions.

The study drew from large-scale medical record data that tracked diagnosis codes over several years, and observers note the timing aligns with the spread of state laws permitting sports wagering after the 2018 Supreme Court decision. States that introduced legal markets earlier recorded the clearest upticks, whereas regions without legalization showed smaller or negligible changes in the same records.

Data collected from electronic health systems indicated consistent growth year over year once betting apps adn retail sportsbooks became available, and the overall 60 percent jump reflects aggregated figures across multiple participating states. Young men between the ages of 18 and 35 accounted for the largest share of new diagnoses, a pattern that mirrors participation rates reported by sportsbooks in those markets.

Analysts who reviewed the records pointed out that the absolute numbers remain relatively low compared with other behavioral health conditions, yet the percentage change stands out because the baseline started from a smaller starting point in 2018. The jump from 3.0 to 4.8 per 100,000 therefore represents a measurable shift that health systems have begun to track more closely.

Men in younger age brackets displayed steeper climbs than other groups, while women and older adults showed more modest increases according to the same dataset. Researchers attribute part of this difference to higher engagement with mobile betting platforms, which became widely accessible after state laws took effect.

Geographic comparisons within the records further illustrated that states with longer-running legal markets posted earlier rises, and the cumulative effect became visible by the early 2020s. Additional states that legalized later are now showing similar trajectories as their markets mature, according to preliminary updates shared by the same research group.

Legal sports betting now operates in dozens of states, and the continued rollout of new markets coincides with the period covered by the health record analysis. Regulators in several jurisdictions have introduced responsible gambling measures such as deposit limits and self-exclusion tools, yet the diagnosis data suggest these steps have not fully offset the observed increase.

Health care providers in states with mature betting markets report greater awareness of gambling disorder screening during routine visits, and electronic record systems now capture more consistent coding for the condition than in prior years. This improved documentation contributes to the visibility of the trend without necessarily indicating a sudden epidemic.

The electronic records examined in the analysis include claims from insured populations across commercial and government plans, and the findings link directly to state-level legalization dates. Cross-referencing these dates with diagnosis timestamps allowed researchers to isolate the effect of policy changes from other national trends.

Similar record reviews conducted in earlier years had already flagged rising interest in gambling-related harms following the first wave of legalization, and the current dataset extends those observations through the most recent available periods. Public health agencies in affected states have begun incorporating these figures into annual behavioral health reports.

Medical organizations that reviewed the results emphasize the value of continued surveillance through existing health record infrastructure, and several state health departments now request regular extracts focused on gambling disorder codes. Such monitoring supports targeted outreach to populations showing elevated rates, particularly young men who interact frequently with betting applications.

Insurance providers and hospital systems have started updating internal guidelines to prompt screening questions about gambling behavior during mental health assessments, and the electronic record increases provide a quantitative basis for these protocol adjustments. The pattern observed in the data offers a concrete reference point for evaluating the reach of existing harm-reduction programs.

The analysis of electronic health records documents a clear rise in gambling disorder diagnoses in states that legalized sports betting, with rates climbing from 3.0 to 4.8 per 100,000 and the sharpest growth concentrated among young men. These findings arrive as more states prepare to expand legal markets, and the data supply a measurable baseline for future comparisons. Health systems and regulators now hold updated figures that can inform ongoing adjustments to screening practices and responsible gambling initiatives across the country.
