目的探讨自我报告的重要性的口味，营养，成本，方便，和体重控制个人的饮食选择，以及这些因素是否不同的人口群体，与健康相关的生活方式的选择（称为健康生活方式），并实际预测饮食behaviors.Design数据是基于2个自我管理的横断面调查的答复。测量的主要结果是水果和蔬菜，快餐，奶酪和早餐谷物，这是确定的基础上回答问题：关于平时和最近的消费和食物diary.Subjects/setting受访者仅仅是一个全国样本的2,967成年人的消费。第一次调查的回应率为71%，第二次调查的回应率为77统计分析单变量分析用于描述重要性评级，双变量分析用于描述重要性评级，（相关性和t检验）用于检查人口统计学和生活方式在重要性测量上的差异，和多变量分析（一般线性模型）被用来预测生活方式聚类成员和食物consumption.Results受访者报告说，口味是最重要的影响他们的食物选择，其次是成本。人口统计学：在所有5个重要指标中，健康的移位方式差异都很明显。营养的重要性和体重控制的重要性预测最好的主题的成员在一个特定的健康生活方式集群。当研究饮食行为时，人口统计学指标和健康生活方式集群的成员资格预测了水果和蔬菜的消费;快餐，奶酪和早餐谷物。注重口味、营养、成本、方便。我们的研究结果表明，营养问题，本身，与大多数人相比，味道和成本的相关性较小。其中一个含义是，营养教育计划应该试图设计和促进营养饮食是美味和廉价的。
Objective To examine the self-reported importance of taste, nutrition, cost, convenience, and weight control on personal dietary choices and whether these factors vary across demographic groups, are associated with lifestyle choices related to health (termed health Lifestyle), and actually predict eating behavior.Design Data are based on responses to 2 self-administered cross-sectional surveys. The main outcomes measured were consumption of fruits and vegetables, fast foods, cheese, and breakfast cereals, which were determined on the basis of responses to questions: about usual and recent consumption and a food diary.Subjects/setting Respondents mere a national sample of 2,967 adults. Response rates were 71% to the first survey and 77% to the second survey (which was sent to people who completed the first survey).Statistical analyses Univariate analyses were used to describe importance ratings, bivariate analyses (correlations and t tests) were used to examine demographic and lifestyle differences on importance measures, and multivariate analyses (general linear models) were used to predict lifestyle cluster membership and food consumption.Results Respondents reported that taste is the most important influence on their food choices, followed by cost. Demographic: and healthy lift style differences were evident across all 5 important measures. The importance of nutrition and the importance of weight control were predicted best by subject's membership in a particular health lifestyle cluster. When eating behaviors were examined, demographic measures and membership in a health lifestyle cluster predicted consumption of fruits and vegetables; fast foods, cheese: and breakfast cereal. The importance placed on taste, nutrition, cost, convenience. and weight control also predicted types of foods consumed.Applications Our results suggest that nutritional concerns, per se, are of less relevance to most people than taste and cost. One implication is that nutrition education programs should attempt to design and promote nutritious diets as being tasty and inexpensive.
