背景关于非洲裔美国人中歧视种族主义措施与健康相关行为之间关联的种族内差异的假设在很大程度上尚未得到探索。方法我们对两项研究进行了二次分析，以检验对一个模型的支持，该模型描述了歧视和种族主义对健康行为影响的几个理论调节因素。第一项研究调查了基于群体的行为信息和种族身份对感知到的种族主义和要求在家进行结直肠癌筛查测试之间关联的影响，样本包括 205 名来自不同地理位置的非裔美国人，这些人在 2019 年至 2020 年期间参与了一项在线实验。结果基于群体的行为信息减弱了感知到的种族主义和对家庭结直肠癌筛查工具包的请求之间的关联。在缺乏基于群体的行为信息的情况下，感知到的种族主义与对种族身份较弱的非裔美国人的筛查套件请求呈正相关，与对种族身份较强的非裔美国人的请求呈负相关。第二项研究考察了 2015 年至 2016 年间，个人和群体感知歧视以及与乳腺癌风险通知相关的行为相关情感信息对 89 名居住在密歇根州的非裔美国女性自我报告的医生沟通的影响。结果显示，在缺乏负面情感信息的情况下，感知到的基于群体的歧视与医生沟通呈正相关，感知到的个人歧视与作为积极情感信息的医生沟通呈负相关。 结论 总之，这些结果支持我们的理论模型，强调歧视和种族主义对非裔美国人健康行为影响的差异，并表明与群体相关的行为信息、种族身份、行为相关的情感信息和歧视目标作为影响的调节因素。讨论了概念化种族主义和歧视的影响以及审查针对种族的干预措施的影响。
BackgroundAssumptions regarding within-race variation in the associations between measures of discrimination racism and health-related behaviors among African Americans have been largely unexplored.MethodsWe conducted secondary analyses of two studies to examine support for a model which describes several theoretical moderators of the effects of discrimination and racism on health behaviors. The first study examined the effects of group-based behavioral information and racial identity on the association between perceived racism and requests for at home colorectal cancer screening tests among a sample of 205 geographically diverse African Americans who participated in an online experiment from 2019 to 2020.ResultsGroup-based behavioral information attenuated the association between perceived racism and requests for at-home screening kit. In the absence of group-based behavioral information, perceived racism was positively associated with screening kit requests for African Americans with weaker racial identity and negatively associated with requests for African Americans with stronger racial identity. The second study examined the influence of personal and group-based perceived discrimination, and behavior-relevant affective information related to a breast cancer risk notification, on 89 Michigan dwelling African American women's self-reported physician communication from 2015 to 2016. Results showed that perceived group-based discrimination was positively associated with physician communication in the absence of negative affective information, and perceived personal discrimination was negatively associated with physician communication as positive affective information increased.ConclusionsTogether, these results support our theoretical model highlighting variation in the effects of discrimination and racism on health behaviors among African Americans, and indicates group-relevant behavioral information, racial identity, behavior relevant affective information, and target of discrimination as moderators of the effect. Implications for conceptualizing the effects of racism and discrimination and for examining racially targeted interventions are discussed.
