介绍我们调查了美国成年人对营养事实小组（NFP）的理解，这需要健康素养（即散文，文件和定量识字技能），以及标签理解和饮食行为之间的关联。MethodsData来自健康信息全国趋势调查，这是美国成年人寻求健康信息的全国代表性调查（N = 3，185）从2013年9月6日至2013年12月30日进行。参与者观看冰淇淋营养标签并回答4个问题，测试他们应用基本算术和理解百分比来解释标签的能力。参与者报告了他们摄入的含糖苏打水，水果和蔬菜。回归分析测试标签的理解，人口统计学特征，和自我报告的饮食behaviors.ResultsApproximately 24%的人不能确定的热量含量的完整的冰淇淋容器，21%的人不能估计的份数等于60克的碳水化合物，42%的人不能估计的影响，每日热量摄入量的前1份，41%的人不能计算出一份食物中每日卡路里的百分比。较高的分数标签的理解与消费更多的蔬菜和更少的含糖苏打水，虽然只有与苏打水的消费量调整后仍然显着的人口factors.ConclusionMany消费者有困难解释营养标签，标签的理解与自我报告的饮食行为。2016年修订的NFP标签可能会通过消除某些计算（例如，每包总卡路里）来解决消费者理解方面的一些缺陷。然而，有些任务仍然需要计算能力（例如，每日卡路里的百分比）。学校在教授理解营养标签所需的数学等技能方面发挥作用。
IntroductionWe examined US adults' understanding of a Nutrition Facts panel (NFP), which requires health literacy (ie, prose, document, and quantitative literacy skills), and the association between label understanding and dietary behavior.MethodsData were from the Health Information National Trends Survey, a nationally representative survey of health information seeking among US adults (N = 3,185) conducted from September 6, 2013, through December 30, 2013. Participants viewed an ice cream nutrition label and answered 4 questions that tested their ability to apply basic arithmetic and understanding of percentages to interpret the label. Participants reported their intake of sugar-sweetened soda, fruits, and vegetables. Regression analyses tested associations among label understanding, demographic characteristics, and self-reported dietary behaviors.ResultsApproximately 24% of people could not determine the calorie content of the full ice-cream container, 21% could not estimate the number of servings equal to 60 g of carbohydrates, 42% could not estimate the effect on daily calorie intake of foregoing 1 serving, and 41% could not calculate the percentage daily value of calories in a single serving. Higher scores for label understanding were associated with consuming more vegetables and less sugar-sweetened soda, although only the association with soda consumption remained significant after adjusting for demographic factors.ConclusionMany consumers have difficulty interpreting nutrition labels, and label understanding correlates with self-reported dietary behaviors. The 2016 revised NFP labels may address some deficits in consumer understanding by eliminating the need to perform certain calculations (eg, total calories per package). However, some tasks still require the ability to perform calculations (eg, percentage daily value of calories). Schools have a role in teaching skills, such as mathematics, needed for nutrition label understanding.
