Multiple studies show an increased prevalence of gambling disorder among African Americans compared to whites. However, few studies take an analytic approach to understanding differences in risk factors by race/ethnicity. Income is inversely associated with gambling disorder; we hypothesized that this association would vary by race/ethnicity. The main objective was to evaluate whether the association between income and gambling disorder varies by race/ethnicity. With data from the baseline visit of a prospective cohort study, Prevention and Etiology of Gambling Addiction Study in the United States, we used multivariable logistic regression analysis to determine whether the association between income and gambling disorder varies by race/ethnicity. 1164 participants were included in the final analyses. Measures included: demographics (age, sex, race/ethnicity, education, employment, annual household income), veteran status, marital status, homelessness, smoking, substance abuse, alcohol abuse, marijuana use, and lifetime gambling disorder diagnosis as derived from Alcohol Use Disorder and Associated Disabilities Interview Schedule. There was no evidence of effect modification by race/ethnicity in the association between income and gambling disorder (global p value = 0.17). Income was associated with increased odds of gambling disorder, but only for those with low income (< $15,000; OR 2.27, 95% CI 1.46, 3.53). There was no evidence that the effect of income on gambling disorder varies by race/ethnicity. For all race/ethnicities combined, low income was associated with significantly increased odds of gambling disorder (OR 2.27, 95% CI 1.46, 3.53). Further research is needed to better understand racial/ethnic differences in gambling disorder.

通过种族/民族差异评估收入与赌博疾病之间的关联

多项研究表明，与白人相比，非裔美国人中赌博疾病的患病率上升。但是，很少有研究采用分析方法来了解种族/民族之间的风险因素差异。收入与赌博障碍成反比；我们假设这种联系会因种族/民族而异。主要目标是评估收入和赌博疾病之间的关联是否因种族/民族而异。根据前瞻性队列研究（美国赌博成瘾的预防和病因研究）的基线随访数据，我们使用了多变量logistic回归分析来确定收入和赌博障碍之间的关联是否因种族/民族而异。最终分析包括1164名参与者。衡量指标包括：受众特征（年龄，性别，种族/族裔，教育，就业，家庭年收入），退伍军人身份，婚姻状况，无家可归，吸烟，滥用药物，酗酒，大麻使用和终身赌博障碍诊断，这些诊断源自酒精使用障碍和相关残障人士访谈时间表。没有证据表明种族/民族在收入与赌博失调之间的关系上有影响（全球p值= 0.17）。收入与赌博疾病几率增加相关，但仅适用于低收入人群（<$ 15,000； OR 2.27，95％CI 1.46，3.53）。没有证据表明收入对赌博疾病的影响因种族/民族而异。对于所有种族/民族，低收入与赌博疾病几率显着增加相关（OR 2.27，95％CI 1.46，3.53）。
