Attention to cancer-relevant communication (e.g., fruit/vegetable intake recommendations) through various media has been shown to be a pivotal step in reduction of the cancer burden, thus underscoring the importance of examining associations between exposure to health media and knowledge of and adherence to fruit/vegetable intake recommendations. The purpose of the present study was to assess factors associated with fruit/vegetable intake knowledge and behavior. The authors analyzed data collected from the 2003 Health Information National Trends Survey to evaluate the effect of fruit/vegetable intake knowledge on behavior, and the relationship of this effect with biobehavioral, sociodemographic, and communication characteristics. Participants who were knowledgeable of fruit/vegetable intake recommendations and consumed at least 5 fruit/vegetable servings per day were classified as informed compliers. Associations were observed for being an informed complier and paying "a lot" of attention to health media on the radio, in the newspaper, and in magazines and "a little" or "some" attention to health media in magazines or on the Internet. The recent explosion of available cancer-related information through various media underscores the importance of examining associations between exposure to health media and knowledge of and adherence to fruit/vegetable intake recommendations.
关注与癌症相关的信息传播（例如，水果/蔬菜摄入量建议），通过各种媒体已经被证明是减轻癌症负担的关键步骤，因此，研究接触健康媒体与了解和遵守水果/蔬菜摄入量建议之间的关联具有重要意义。本研究的目的是评估与水果/蔬菜摄入量知识和行为相关的因素。作者分析了 2003 年健康信息国家趋势调查收集的数据，以评估水果/蔬菜摄入量知识对行为的影响，以及这种影响与生物行为、社会人口统计学和传播特征的关系。将了解水果/蔬菜摄入量建议并每天至少摄入 5 份水果/蔬菜的参与者归类为知情遵从者。与作为知情遵从者和“大量”关注广播、报纸、杂志中的健康媒体以及“少量”或“一些”关注杂志或互联网上的健康媒体相关联。最近，各种媒体上提供的与癌症相关的信息大量涌现，这突显了研究接触健康媒体与了解和遵守水果/蔬菜摄入量建议之间的关联的重要性。
