This application describes a planned cohort study of 80,000 white and 45,000 black adult Seventh-day Adventists, enrolled from across the U.S. Questions not easily addressed by other study populations, can be answered. Taking advantage of the unusual dietary habits of Adventists, the special focus of this application is an association between soy intake, calcium intake, and cancers of the breast, prostate and colon. About half of black and white Adventists consume similar quantities of soy to that used in China or Singapore. Adventists also have a wide variance in intake of calcium. The increasing use of soy and calcium supplements by the American population needs further evidential support. Another strength of the proposed research is the proven ability to enroll and follow a large and cooperative cohort of black Adventists. The very high incidence and mortality ascribed to prostate cancer in black men may be associated with their dietary habits. Subjects will be enrolled church by church using a pretested plan whereby institutional media and respected members at individual churches promote the study. Subjects will complete a comprehensive questionnaire which is already developed and pretested. Cancer surveillance during follow-up will be by matching with state tumor registries where possible, matching with the National Death Index, and by obtaining and coding hospitalization records as necessary. Calibration studies in both black and white Adventists will allow bias correction. We believe that it is important to also gather blood, urine and subcutaneous fat from the subjects, and have a largely pretested plan to accomplish this. This will be further tested for feasibility at a location away from Loma Linda during Year 0 1 of the present study. The Adventist population has been cooperative with epidemiologic research for many years and has some unusual strengths as a research population, including the virtual absence of confounding by tobacco and alcohol, the wide range of dietary habits and the widespread use of soy products. They have made important contributions to the understanding of diet and chronic disease in the past. This larger study will provide much greater statistical power, more accurate and documented exposure assessment, and will also include a large cohort of black Adventists.

该应用程序描述了一项计划中的队列研究，该研究对来自美国各地的 80,000 名白人和 45,000 名黑人成年基督复临安息日会信徒进行了计划中的队列研究。其他研究人群不易解决的问题可以得到解答。利用复临信徒不寻常的饮食习惯，该应用的特别重点是大豆摄入量、钙摄入量与乳腺癌、前列腺癌和结肠癌之间的关联。大约一半的黑人和白人复临信徒消费的大豆数量与中国或新加坡的消费量相当。复临信徒对钙的摄入量也有很大差异。美国人越来越多地使用大豆和钙补充剂需要进一步的证据支持。拟议研究的另一个优势是已证明能够招募和跟踪大量合作的黑人复临信徒群体。黑人前列腺癌的高发病率和死亡率可能与其饮食习惯有关。受试者将使用预先测试的计划逐个教会进行登记，机构媒体和各个教会受人尊敬的成员将通过该计划来促进这项研究。受试者将完成一份已经开发和预先测试的综合调查问卷。随访期间的癌症监测将尽可能与州肿瘤登记处进行匹配，与国家死亡指数进行匹配，并根据需要获取和编码住院记录。对黑人和白人复临信徒的校准研究将允许偏差纠正。我们认为，收集受试者的血液、尿液和皮下脂肪也很重要，并制定一个经过预先测试的计划来实现这一目标。在本研究的第 0-1 年期间，将在远离洛马琳达的地点进一步测试其可行性。复临信徒群体多年来一直与流行病学研究合作，并且作为研究群体具有一些不寻常的优势，包括几乎不存在烟草和酒精的混淆、广泛的饮食习惯和广泛使用豆制品。他们过去为了解饮食和慢性病做出了重要贡献。这项更大规模的研究将提供更强大的统计能力、更准确和记录的暴露评估，并且还将包括一大批黑人复临信徒。
