Prevalence of gambling disorders in a primary care setting

Pathologic gambling prevalence seems to be increasing as opportunities for gambling increase. Prevalence may be different in a primary care setting compared with population-based studies.

To determine the gambling disorder prevalence in a primary care setting and to investigate associations between gambling disorders and proximity to a casino, substance abuse, health ratings, age, sex, and socioeconomic status.

Cross-sectional survey of 1394 patients presenting to their primary care physicians between November 1, 1997, and April 1, 1998.

Three primary care clinics in Wisconsin.

Adults aged 18 years and older.

Gambling disorders, defined by scores of 3 or greater on the South Oaks Gambling Screen (SOGS), and information about drug use (alcohol, tobacco, and marijuana), overall health, specific health symptoms, age, sex, race, and socioeconomic status.

A total of 1051 patients completed the survey. More than 80.0% of the patients had gambled, and 6.2% met the criteria for gambling disorders. Gambling disorders were more prevalent in men, nonwhites, and patients from lower socioeconomic groups. Patients with gambling disorders were more likely to use tobacco and abuse alcohol compared with nonproblem gamblers. No relation was seen between marijuana use and gambling disorders. Patients with gambling disorders rated their health more poorly and reported more severe symptoms of heartburn and backache.

A considerable percentage of patients presenting to primary care clinics are affected by their need to gamble. There is significant comorbidity with tobacco use and alcohol abuse. Primary care physicians should consider asking about gambling habits in high-risk patients.
