目的：美国家庭购买的大多数杂货都是工业加工的，但目前尚不清楚加工水平如何影响饮食质量。我们试图确定加工水平是否与杂货店购买的饮食质量相关。设计：我们分析了2012-2013年全国家庭食品收购和购买调查的食品杂货购买数据。NOVA框架将家庭杂货购买分类为最低限度加工，加工烹饪配料，加工食品或超加工食品。每个加工水平的能量份额（能量百分比; %E）和健康饮食指数-2015（HEI-2015）的组成部分和总得分计算每个家庭的购买。通过多变量线性回归确定加工食品和超加工食品的%E分别与HEI-2015总分之间的关联。家庭购买的食品最高与最低超加工食品购买和HEI-2015总分设置：美国。参与者：3961个家庭的全国代表性样本。结果如下：加工食品和超加工食品分别提供了购买能量的9个中心点2（se 0中心点3）%和55个中心点8（se 0中心点6）%。平均HEI-2015评分为54中心点7（se 0中心点4）。用10%E从最低限度加工的食品和加工的烹饪成分中替代超加工食品，使HEI-2015总评分降低了1个中心点8分（β = -1个中心点8; 95%CI-2个中心点0，-1个中心点5）。购买加工食品与饮食质量无关。在购买超加工食品的家庭中，HEI-2015评分的家庭结论：增加购买最低限度加工食品，减少购买超加工食品，并在每个加工水平上选择更健康的食品，可以改善饮食质量。
Objective: The majority of groceries purchased by US households are industrially processed, yet it is unclear how processing level influences diet quality. We sought to determine if processing level is associated with diet quality of grocery purchases. Design: We analysed grocery purchasing data from the National Household Food Acquisition and Purchase Survey 2012-2013. Household grocery purchases were categorized by the NOVA framework as minimally processed, processed culinary ingredients, processed foods or ultra-processed foods. The energy share of each processing level (percentage of energy; %E) and Healthy Eating Index-2015 (HEI-2015) component and total scores were calculated for each household's purchases. The association between %E from processed foods and ultra-processed foods, respectively, and HEI-2015 total score was determined by multivariable linear regression. Foods purchased by households with the highest v. lowest ultra-processed food purchases and HEI-2015 total score Setting: USA. Participants: Nationally representative sample of 3961 households. Results: Processed foods and ultra-processed foods provided 9 center dot 2 (se 0 center dot 3) % and 55 center dot 8 (se 0 center dot 6) % of purchased energy, respectively. Mean HEI-2015 score was 54 center dot 7 (se 0 center dot 4). Substituting 10 %E from minimally processed foods and processed culinary ingredients for ultra-processed foods decreased total HEI-2015 score by 1 center dot 8 points (beta = -1 center dot 8; 95 % CI -2 center dot 0, -1 center dot 5). Processed food purchases were not associated with diet quality. Among households with high ultra-processed food purchases, those with HEI-2015 score Conclusions: Increasing purchases of minimally processed foods, decreasing purchases of ultra-processed foods and selecting healthier foods at each processing level may improve diet quality.
