目的：尽管人们担心近年来流行病学研究的参与率下降，但讨论招募研究参与者的障碍或优化反应率的策略的论文相对较少。本报告描述了与不参与基于人群的乳腺癌病例对照研究相关的因素，并讨论了克服参与障碍的方法。方法：计算卡罗莱纳州乳腺癌研究 (CBCS) 参与者的接触率和合作率，按病例状态、年龄、种族和访谈者种族进行分层。还比较了部分和完全缓解者的人口统计学和乳腺癌危险因素特征。结果：接触率和合作率因病例/对照状态和人口统计学特征而异。对照组、年轻女性和黑人女性的接触率较低。对照组、老年妇女和黑人案例中的合作率较低。当参与者和采访者在种族上一致时，黑人和非黑人女性的合作率都较高。结论：种族和年龄亚组之间的招募障碍似乎有所不同，这表明可能需要根据人口特征为潜在参与者量身定制聊天招募策略。已实施策略来提高本研究和其他流行病学研究的响应率；然而，这一领域还需要更多的研究和创新。安流行病学 1999；9：188-195。 (C) 1999 Elsevier Science Inc. 保留所有权利。
PURPOSE: Despite concerns about declining participation rates in epidemiologic studies in recent years, relatively few papers have discussed obstacles to recruiting study participants or strategies for optimizing response rates. This report describes factors associated with nonparticipation in a population-based, case-control study of breast cancer and discusses ways to overcome barriers to participation.METHODS: Contact and cooperation rates were calculated for participants in the Carolina Breast Cancer Study (CBCS), stratified by case status, age, race, and race of interviewer. Demographic and breast cancer risk factor characteristics of partial and full responders also were compared.RESULTS: Contact rates and cooperation rates varied by case/control status and demographic characteristics. Contact rates were lower among controls, younger women, and black women. Cooperation rates were lower among controls, older women, and black cases. Cooperation rates were higher among both black and nonblack women when participants and interviewers were concordant on race.CONCLUSIONS: Obstacles to recruitment seem to differ among race and age subgroups, suggesting chat recruitment strategies may need to be tailored to potential participants based upon demographic characteristics. Strategies have been implemented to improve response rates in this and other epidemiologic studies; however, additional research and innovation in this area are needed. Ann Epidemiol 1999;9:188-195.
