营养声明是一种常用的营销策略，但声明与产品营养质量之间的关联尚不清楚。目的是检查带有营养声明的包装食品和饮料购买比例的趋势，声明是否与改善营养状况相关，以及带有声明的购买比例是否因种族/民族或社会经济地位而异。这项横断面研究调查了 2008 年至 2012 年期间 40,000 个美国家庭的交易级数据库中购买的超过 8,000 万份食品和饮料的营养声明。卡方检验用于检查低含量/无含量声称的购买比例是否随时间变化或因种族/民族或家庭社会经济地位而变化。使用 t 检验对汇总交易进行检查，以比较产品的总体营养状况以及按食品和饮料组划分的营养状况。 13% 的食品和 35% 的饮料购买时声称含量低。索赔的普遍程度并没有随着时间的推移而改变。低脂肪声称在食品和饮料中最为普遍（分别为 10% 和 19%），其次是低热量（3%、9%）、低糖（2%、8%）和低钠（两者均为 2%）。与没有声明的购买相比，具有低含量声明的购买具有较低的平均能量、总糖、总脂肪和钠密度。然而，特定声明类型和特定营养密度之间的关联差异很大，并且购买具有给定低含量声明的产品并不一定能提供更好的整体营养成分，甚至相对于没有声明的产品而言，所声明的营养成分也不一定更好。此外，食品和饮料类别中的声称与营养密度之间的关联存在很大的异质性。不同声明类型和食品和饮料类别的营养密度差异表明，声明可能对某些食品或营养素具有不同的效用，并且在某些情况下可能会误导食品的整体营养质量。
Nutrient claims are a commonly used marketing tactic, but the association between claims and nutritional quality of products is unknown. The objective is to examine trends in the proportion of packaged food and beverage purchases with a nutrient claim, whether claims are associated with improved nutritional profile, and if the proportion of purchases with claims differs by race/ethnicity or socio-economic status. This cross-sectional study examines nutrient claims on over 80 million food and beverage purchases from a transaction-level database of 40,000 US households from 2008–2012. Chi-square tests were used to examine whether the proportion of purchases with a low-/no-content claim changed over time or differed by race/ethnicity or household socio-economic status. Pooled transactions were examined using t-tests to compare products’ nutritional profiles overall and by food and beverage group. Thirteen percent of food and 35% of beverage purchases had a low-content claim. Prevalence of claims did not change over time. Low-fat claims were most prevalent for both foods and beverages (10% and 19%, respectively), followed by low-calorie (3%, 9%), low-sugar (2%, 8%), and low-sodium (2% for both). Compared to purchases with no claim, purchases with any low-content claim had lower mean energy, total sugar, total fat, and sodium densities. However, the association between particular claim types and specific nutrient densities varied substantially, and purchases featuring a given low-content claim did not necessarily offer better overall nutritional profiles or even better profiles for the claimed nutrient relative to products without claims. In addition, there was substantial heterogeneity in associations between claims and nutritional density within food and beverage groups. Variations in nutrient density by claim type and food and beverage group suggests that claims may have differential utility for certain foods or nutrients and in some cases may mislead about the overall nutritional quality of the food.
