DESCRIPTION (provided by applicant): This study aims to examine the effects of ethnicity, socioeconomic status (SES) and acculturation on breast cancer screening tests. Various studies document disparities between Latina (Hispanic) and non-Latina white women in incidence and mortality rates of breast cancer, as well as survival rates. Several studies indicate that Latina women receive fewer breast cancer screening tests than non-Latina whites, possibly accounting for some of the observed differences in breast cancer mortality and survival rates. Research on acculturation (the process by which immigrant groups espouse the values, beliefs and behaviors of a dominant culture), suggests that Latino cultural values may be associated with decreased screening. Other research indicates that SES and other structural factors (e.g., access to health care) account for differences in screening. The proposed study will significantly contribute to the literature on breast cancer screening among Latina and non-Latina white women by testing theoretical models on the effects of cultural and sociodemographic factors on cancer screening, as well as the mechanisms that mediate these effects. Using data from the Cancer Control Supplement of the 1992 National Health Interview Survey, the study will examine two screening behaviors: recent mammography and clinical breast examination and among Latinas and non-Latina whites. The following research questions will be addressed: (1) What is the relationship between ethnicity, sociodemographic variables (SES, age), acculturation and cancer screening?; (2) Are ethnicity and acculturation related to breast cancer screening behaviors even when controlling for age and socioeconomic status variables? ; and (3) To what extent do cancer knowledge, beliefs about the chances of survival of cancer, and access to health care mediate the relationships between ethnicity, acculturation, SES and cancer screening? Few studies have tested mediating processes involved in the relationship between acculturation, SES, age, and screening. Furthermore, we know of no published studies which have tested mediation models among nationally representative samples of Latina and non-Latina white women in the United States.

描述（由申请人提供）： 本研究旨在探讨种族、社会经济地位 (SES) 和文化适应对乳腺癌筛查测试的影响。各种研究记录了拉丁裔（西班牙裔）和非拉丁裔白人女性在乳腺癌发病率、死亡率以及生存率方面的差异。多项研究表明，拉丁裔女性接受的乳腺癌筛查测试少于非拉丁裔白人，这可能是观察到的乳腺癌死亡率和生存率差异的一些原因。对文化适应（移民群体拥护主流文化的价值观、信仰和行为的过程）的研究表明，拉丁裔文化价值观可能与筛选减少有关。其他研究表明，社会经济地位和其他结构性因素（例如获得医疗保健的机会）是筛查差异的原因。拟议的研究将通过测试文化和社会人口因素对癌症筛查影响的理论模型以及介导这些影响的机制，为拉丁裔和非拉丁裔白人女性乳腺癌筛查的文献做出重大贡献。该研究将利用 1992 年全国健康访问调查的癌症控制补充资料中的数据，检查拉丁裔和非拉丁裔白人的近期乳房 X 光检查和临床乳房检查的两种筛查行为。将解决以下研究问题：（1）种族、社会人口变量（SES、年龄）、文化适应和癌症筛查之间的关系是什么？ (2) 即使控制了年龄和社会经济地位变量，种族和文化适应是否与乳腺癌筛查行为相关？ ; (3) 癌症知识、对癌症生存机会的信念以及获得医疗保健的机会在多大程度上调节种族、文化适应、社会经济地位和癌症筛查之间的关系？很少有研究测试涉及文化适应、社会经济地位、年龄和筛选之间关系的中介过程。此外，据我们所知，还没有已发表的研究在美国具有全国代表性的拉丁裔和非拉丁裔白人女性样本中测试了中介模型。
