目的：根据谷物营养质量和营销策略以及家庭社会人口特征描述 2008 年美国的即食 (RTE) 谷物购买情况。设计：一年内购买情况的横断面研究。每种谷物都被分配到四个营养质量类别之一（基于营养成分指数，NPI），以及基于电视曝光和包装分析的四个广告类别之一（针对儿童、针对家庭、针对成人和无电视广告）。计算谷物类别的购买指标中位数和分布，并比较不同社会人口群体的分布。设置：具有完整标签和营养成分的即食谷物 (n 249)。主题：根据从 Nielsen Homescan（全国代表性家庭小组）获得的家庭社会人口特征进行的即食谷物购买量。结果：有一个或多个孩子的家庭对即食谷物的购买量最高，非裔美国人和亚洲家庭以及收入、收入的家庭中最低。
Objective: To describe ready-to-eat (RTE) cereal purchases in 2008 in the USA according to cereal nutritional quality and marketing strategy and household sociodemographic characteristics.Design: Cross-sectional study of purchases in one year. Each type of cereal was assigned to one of four nutrition quality categories (based on Nutrient Profile Index, NPI) and one of four advertising categories based on television exposure and analysis of packaging (child-targeted, family-targeted, adult-targeted and no television advertising). Medians and distributions of purchase indicators were calculated for the cereal categories and the distributions were compared across sociodemographic groups.Setting: RTE cereals (n 249) with complete label and nutritional content.Subjects: RTE cereal purchases according to household sociodemographic characteristics obtained from Nielsen Homescan, a nationally representative panel of households.Results: Purchases of RTE cereals were highest in households with one or more child and lowest in African-American and Asian households, as well as those earning,
