The purpose of this study was to determine the frequency and character of policy statements in epidemiologic reports.
The first author followed a standardized protocol and reviewed a random sample of articles selected from the American Journal of Epidemiology, Annals of Epidemiology, and Epidemiology. The second author reviewed all articles with policy statements and a 10% sample without such statements.
Overall, 23.8% of the articles contained policy statements. Annals of Epidemiology and the American Journal of Epidemiology had similar frequencies of articles with policy statements (30% and 26.7%, respectively), while Epidemiology evidenced the lowest frequency (8.3%). The majority of policy statements (55%) pertained to public health practice; 27.5% involved clinical practice, and the remainder (17.5%) focused on corporate policies, regulatory actions, or undefined arenas. The frequency of policy statements differed according to first author's affiliation, type of publication, area of research, research design, and study population.
Although a minority of publications included policy statements, the inclusion of a statement seemed to be influenced by specific study characteristics.
本研究旨在确定流行病学报告中政策声明的频率和特征。
第一作者遵循标准化方案，对从《美国流行病学杂志》《流行病学纪事》和《流行病学》中随机抽取的文章样本进行了审查。第二作者审查了所有带有政策声明的文章以及10%没有此类声明的样本文章。
总体而言，23.8%的文章包含政策声明。《流行病学纪事》和《美国流行病学杂志》中带有政策声明的文章频率相似（分别为30%和26.7%），而《流行病学》中的频率最低（8.3%）。大多数政策声明（55%）与公共卫生实践相关；27.5%涉及临床实践，其余（17.5%）关注公司政策、监管行动或未明确的领域。政策声明的频率因第一作者的所属机构、出版物类型、研究领域、研究设计和研究人群而异。
虽然少数出版物包含政策声明，但声明的纳入似乎受到特定研究特征的影响。
