Knowledge of and adherence to fruit and vegetable recommendations and intakes: results of the 2003 health information national trends survey.

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.
