It is unclear whether dietary quality varies by geography in the US.
Assess patterns in packaged food purchases (PFPs).
We characterized variation in PFP quality from 2008 to 2018 by 1) examining geographic clustering and 2) using regression analysis to control for household characteristics.
Lower quality purchases clustered in the Southeast and Appalachia, whereas higher quality purchases clustered in the West and Northeast. Spatial patterns were similar for low socioeconomic households but not high socioeconomic households. Geographic differences in quality remained after controlling for demographic composition.
This analysis should inform research into systemic drivers of PFP quality.
在美国，饮食质量是否因地理位置而异尚不清楚。
评估包装食品购买（PFPs）的模式。
我们通过以下两种方法来描述 2008 年至 2018 年间 PFPs 质量的变化：1）检查地理聚类情况；2）使用回归分析控制家庭特征。
低质量购买集中在东南部和阿巴拉契亚地区，而高质量购买则集中在西部和东北部。低社会经济家庭的空间模式相似，但高社会经济家庭的模式不同。在控制人口构成后，质量的地理差异仍然存在。
本分析应能为研究 PFPs 质量的系统驱动因素提供信息。
