North American Indigenous (NAI) communities have identified alcohol use as a primary health concern. Experiences of racial discrimination are associated with greater alcohol use, but findings are mixed regarding the role of culture in this relationship. The goal of the present study was to examine the role of culture in the association between racial discrimination and alcohol use.
Across two studies (Study 1: N = 52; Study 2: N = 1743), NAI adolescents living on or near NAI reservations who reported recent alcohol use completed self-report measures of racial discrimination, cultural affiliation, and alcohol use (e.g., frequency).
Bivariate correlations revealed a significant positive association between racial discrimination and alcohol use (Study 1: r = 0.31, p = 0.029; Study 2: r = 0.14, p < 0.001) but not between cultural affiliation and alcohol use. Racial discrimination and cultural affiliation were significantly positively correlated in Study 1 (r = 0.18, p < 0.001), but not in Study 2. Across both studies, the interactions between racial discrimination and cultural affiliation significantly predicted alcohol use in unadjusted models (Study 1: b = 0.70, SE = 0.32, p = 0.033, 95% CI [0.06, 1.33]; Study 2: b = 0.01, SE = 0.01, p = 0.041, 95% CI [0.001, 0.03]), such that the association between racial discrimination and alcohol use was stronger for adolescents reporting high (vs. low) levels of cultural affiliation. In adjusted models controlling for age and sex, the interaction between racial discrimination and cultural affiliation remained significant in Study 2 (b = 0.01, SE = 0.01, p = 0.0496, 95% CI [0.00002, 0.03]) but was no longer significant in Study 1.
Findings speak to the need to reduce racial discrimination against NAI youth and to consider youths' different needs based on level of cultural affiliation to reduce subsequent alcohol consumption.
北美原住民（NAI）社区已将饮酒确定为主要的健康问题。种族歧视经历与更多的饮酒行为相关，但关于文化在这种关系中的作用，研究结果不一。本研究的目的是探讨文化在种族歧视与饮酒之间的关联中所起的作用。
在两项研究中（研究1：N = 52；研究2：N = 1743），居住在NAI保留地或附近且报告近期有饮酒行为的NAI青少年完成了关于种族歧视、文化归属和饮酒情况（如频率）的自我报告测量。
双变量相关性分析显示，种族歧视与饮酒之间存在显著的正相关（研究1：r = 0.31，p = 0.029；研究2：r = 0.14，p < 0.001），但文化归属与饮酒之间不存在相关性。在研究1中，种族歧视与文化归属显著正相关（r = 0.18，p < 0.001），但在研究2中并非如此。在两项研究中，在未调整的模型中，种族歧视与文化归属之间的交互作用显著预测了饮酒情况（研究1：b = 0.70，标准误 = 0.32，p = 0.033，95%置信区间[0.06, 1.33]；研究2：b = 0.01，标准误 = 0.01，p = 0.041，95%置信区间[0.001, 0.03]），即对于报告文化归属水平高（与低相比）的青少年，种族歧视与饮酒之间的关联更强。在控制年龄和性别的调整模型中，种族歧视与文化归属之间的交互作用在研究2中仍然显著（b = 0.01，标准误 = 0.01，p = 0.0496，95%置信区间[0.00002, 0.03]），但在研究1中不再显著。
研究结果表明，有必要减少对NAI青年的种族歧视，并根据文化归属水平考虑青年的不同需求，以减少随后的酒精消费。
