On November 16, 2009, the U.S. Preventive Services Task Force (USPSTF) released new breast cancer screening recommendations, resulting in considerable controversy.
The purpose of this investigation was to assess the volume and framing of the public discourse around the mammography recommendations and determine if women were knowledgeable about the new recommendations.
Two different types of data collection methods were used for this study: (1) a content analysis of news stories and social media posts around the time of the USPSTF announcement and (2) a web-based survey of women aged 40-74 years conducted through Knowledge Networks from December 17, 2009, to January 6, 2010. Data were analyzed in 2010.
The survey sample included 1221 women aged 40-74 years who had never had breast cancer. The majority of the articles and posts (51.9%) did not support the screening recommendations, and 17.6% were supportive. Less than one quarter of the sample could identify the new recommendations for women aged 40-49 years and 50-74 years. Results from logistic regression analyses identified characteristics associated with correct knowledge of the recommendations for each age group. Level of attention paid to the recommendations was significantly associated with accurate knowledge of the recommendations for each age group. Having a mammogram within the past 2 years, "other" race (i.e., not black or white), and having higher levels of education, confidence that recommendations were based on the latest research, and attention paid to the new guidelines were all significantly and positively associated with correct knowledge of the new recommendation for women aged 40-49 years.
The new recommendations confused women (30.0%) more than they helped them understand when to get a mammogram (6.2%). Confusion was greatest among women aged 40-49 years and women who had never had a mammogram or who had one more than 2 years ago. Communication about future recommendations should be pretested to identify strategies and language that may reduce confusion among providers, consumers, and advocacy groups.
2009 年 11 月 16 日，美国预防服务工作组（USPSTF）发布了新的乳腺癌筛查建议，引发了广泛争议。
本研究旨在评估围绕乳房 X 光检查建议的公众讨论的规模和框架，并确定女性是否了解新建议。
本研究使用了两种不同的数据收集方法：（1）USPSTF 公告发布前后的新闻报道和社交媒体帖子的内容分析；（2）通过 Knowledge Networks 于 2009 年 12 月 17 日至 2010 年 1 月 6 日对 40-74 岁女性进行的基于网络的调查。数据分析于 2010 年进行。
调查样本包括 1221 名从未患有乳腺癌的 40-74 岁女性。大多数文章和帖子（51.9%）不支持筛查建议，17.6%表示支持。不到四分之一的样本能够识别出针对 40-49 岁和 50-74 岁女性的新建议。逻辑回归分析的结果确定了与每个年龄组正确了解建议相关的特征。对建议的关注程度与每个年龄组对建议的准确了解显著相关。在过去 2 年内接受过乳房 X 光检查、“其他”种族（即非黑或白人）、受教育程度较高、对建议基于最新研究的信心以及对新指南的关注，与正确了解 40-49 岁女性的新建议显著正相关。
新建议让女性感到困惑（30.0%）多于帮助她们了解何时进行乳房 X 光检查（6.2%）。40-49 岁的女性以及从未接受过乳房 X 光检查或接受检查超过 2 年的女性困惑最大。关于未来建议的沟通应进行预测试，以确定可能减少提供者、消费者和倡导团体混淆的策略和语言。
