This qualitative study examines consumers' attitudes about key messages, alternative messages, and various formats of the 1995 US Dietary Guidelines for Americans. Five focus groups were conducted using a discussion guide based on previous research and the research concerns of the 1995 Dietary Guidelines Advisory Committee. The presentation orders of the guidelines, guideline alternatives, and formats were varied to prevent bias. Forty consumers (age range, 25 to 43 years) participated: 3 groups of women and 2 groups of men. Participants were not familiar with the Dietary Guidelines but had heard some messages. Consumers were confused by several guideline messages. First, the messages to "Maintain or improve your weight" and "Balance the food you eat with physical activity" did not make sense to them. Second, respondents were confused by the term "balance" in several different contexts. The participants most preferred a shortened format, followed by a 2-tiered or grouped format, with the 1995 list of Dietary Guidelines falling last. Most of the Dietary Guidelines could be better communicated to the public using shorter, clearer messages, especially for the weight and physical activity, and fat guidelines. Decreasing the number of guidelines or using a tiered/grouped format could make the Dietary Guidelines more useful to consumers.
这项定性研究考察了消费者对1995年《美国膳食指南》的关键信息、替代信息以及各种形式的态度。基于先前的研究和1995年膳食指南咨询委员会的研究关注点,使用讨论指南开展了五次焦点小组讨论。指南、指南替代方案和形式的展示顺序有所不同,以防止偏差。40名消费者(年龄范围为25至43岁)参与其中:3组女性和2组男性。参与者不熟悉膳食指南,但听过一些相关信息。消费者对一些指南信息感到困惑。首先,“保持或改善体重”以及“使饮食与体育活动相平衡”这些信息对他们来说没有意义。其次,受访者对“平衡”一词在几种不同语境中的含义感到困惑。参与者最喜欢简短形式,其次是两级或分组形式,1995年的膳食指南列表排在最后。使用更简短、更清晰的信息,尤其是关于体重、体育活动和脂肪的指南信息,大多数膳食指南信息能够更好地传达给公众。减少指南数量或采用分级/分组形式可能会使膳食指南对消费者更有用。
