Three studies were identified that examined the comorbidity of pathological gambling and DUDs among ethnic groups18,56,57. Barry and colleagues56 found risk for comorbid past-year pathological gambling was not significantly different for Blacks and Whites for AUD (odds ratios, OR, of 4.3 for Blacks vs. 6.2 for Whites), DUD (3.4 vs. 2.9), nicotine dependence (3.1 vs.7.1), and any substance use disorder (AUD or DUD, 4.2 vs. 6.7), although Blacks had a significantly stronger relationship between subsyndromal gambling and any substance use disorder than Whites. Similarly, Barry and colleagues57 found ORs that were not significantly different for Hispanics and Whites for past-year pathological gambling with AUD (6.81 for Hispanics vs. 6.21 for Whites), DUD (1.75 vs. 2.90), nicotine dependence (7.13 vs. 7.14), and any substance use disorder (3.67 vs. 6.74), although Hispanics had a significantly stronger relationship between subsyndromal gambling and any substance use disorder as well as nicotine dependence than Whites. Luczak and Wall18 found lifetime probable pathological gambling was significantly related to DSM-IV AUDs among Chinese men (OR =13.33) and White men (OR = 9.36), but not among Korean men (OR = 2.53), but no associations were significantly different for women.
