As the coronavirus pandemic stretched on, millions of U.S. children and their families faced food insecurity. However, limited empirical studies have systemically investigated food insecurity and food insecurity transitions among households with children in the context of the COVID-19 pandemic. This cross-sectional study was based on a nationally representative sample of households with children (including all 50 states and the District of Columbia, n = 20,543 households) collected by the 2020 Household Pulse Survey. Two generalized estimating equations models were developed, and the results indicated that most sociodemographic factors contributing to severe household food insecurity during the pandemic were similar to those before the pandemic. However, having children enrolled in schools did not protect families from food insecurity during COVID-19. Furthermore, among previously food-secure households, those that were relatively disadvantaged transitioned into food insecurity during COVID-19. As the pandemic persists, more coordinated efforts to ensure all households with children receive adequate nutrition are desperately needed.

随着冠状病毒大流行的蔓延，数以百万计的美国儿童及其家庭面临着粮食安全问题。但是，有限的经验研究已系统地调查了在COVID-19大流行情况下有子女的家庭中的粮食不安全状况和粮食不安全状况的转变。这横断面研究是基于家庭的儿童（包括所有50个州和哥伦比亚特区的全国代表性样本，ñ= 2020个家庭）。建立了两个广义估计方程模型，结果表明，大流行期间导致严重家庭粮食不安全的大多数社会人口统计学因素与大流行之前相似。但是，在COVID-19期间，让孩子入学并不能保护家庭免受粮食不安全的困扰。此外，在以前粮食安全的家庭中，处于不利地位的家庭在COVID-19期间转变为粮食不安全的家庭。随着大流行的持续存在，迫切需要更加协调一致的努力，以确保所有有孩子的家庭获得足够的营养。
