The study aims to disentangle the effects of age, socioeconomic status (SES) and ethniclty , specifically, 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 older 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 account for differences in screening. The proposed study will significantly contribute to the literature on breast cancer screening among Latina women by testing a theoretical model on the effects of age, cultural and socioeconomic status factors on cancer screening, as well as mechanisms that mediate these effects. Using data from the Cancer Control Supplement of the 1992 National Health Interview Survey, the study will examine three screening behaviors: recent clinical breast examination and mammography, and frequency of breast self-examination. The following research questions will be addressed: (1) What is the relationship between age, acculturation and cancer screening?; (2) Is acculturation related to breast cancer screening behaviors even when controlling for age and socioeconomic status variables?; (3) To what extent do cancer knowledge, beliefs about the chances of survival of cancer, and quality &health care mediate the relationships between acculturation, SES and cancer screening?; and (4) Does age have a direct effect on screening behaviors? Few studies have tested mediating processes involved in the relationship between age, acculturation, SES, and screening. Furthermore, we know of no published studies which have tested mediation models among a nationally representative sample of Latina women in the United States.

该研究旨在解散年龄，社会经济地位（SES）和民族的影响，尤其是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）与非拉丁裔白人妇女之间的差异，其发病率和乳腺癌死亡率以及生存率。几项研究表明，老年拉丁女性接受的乳腺癌筛查测试少于非latina白人，这可能考虑了观察到的乳腺癌死亡率和存活率的某些差异。适应研究的研究（移民群体拥护主导文化的价值观，信念和行为的过程）表明，拉丁裔文化价值可能与筛查减少有关。其他研究表明，SES和其他结构因素解释了筛查的差异。拟议的研究将通过测试有关年龄，文化和社会经济状况因素对癌症筛查的影响的理论模型以及介导这些影响的机制，从而为拉丁裔女性乳腺癌筛查的文献做出重大贡献。使用1992年国家健康访谈调查的癌症控制补充剂的数据，该研究将检查三种筛查行为：最近的临床乳房检查和乳房X线摄影以及乳房自我检查的频率。将解决以下研究问题：（1）年龄，适应和癌症筛查之间的关系是什么？ （2）即使控制年龄和社会经济状况变量，适应性是否与乳腺癌筛查行为有关？ （3）癌症知识，对癌症生存机会的信念以及质量与卫生保健在多大程度上介导了适应，SES和癌症筛查之间的关系？ （4）年龄对筛查行为有直接影响吗？很少有研究测试了与年龄，适应，SES和筛查之间关系的中介过程。此外，我们知道没有发表的研究，该研究已经测试了美国国家代表性的拉丁裔妇女样本中的调解模型。
