Abstract：
The impact that the coronavirus disease 2019 (COVID-19)-related early lockdown has had on dietary habits of the population and on food insecurity is unknown.
The aim of this study was to document the change in diet quality and in food insecurity observed during the COVID-19-related early lockdown. We hypothesized that the lockdown was associated with a deterioration in overall diet quality and an increase in food insecurity.
Data are from a COVID-19 subsample of NutriQuébec, a web-based cohort destined to study temporal changes in dietary habits among adults in Quebec, Canada. Participants completed questionnaires before (between June 2019 and February 2020) and during (April to May 2020) early lockdown, including a validated web-based 24-h recall (n = 853) and a questionnaire on food security (n = 922). Primary study outcomes were temporal changes in diet quality measured by the Healthy Eating Index (HEI)-2015 and in the prevalence of food insecurity.
There was a small increase in the HEI-2015 during the COVID-19 early lockdown compared with baseline (+1.1 points; 95% CI: 0.6, 1.5), mostly due to small improvements in the intakes of whole grains, greens and beans, refined grains, total vegetables, total dairy, seafood and plant proteins, added sugar, and total protein subscores of the HEI-2015. Exploratory analyses suggested that individuals aged 18-29 y (+3.6 points; 95% CI: 2.4, 4.7), participants with lower education (+1.9 points; 95% CI: 1.3, 2.6), or with obesity (+3.8 points; 95% CI: 2.7, 4.8) showed particularly important increases in the HEI-2015. The prevalence of food insecurity was reduced from 3.8% at baseline to 1.0% during the early lockdown (prevalence ratio = 0.27; 95% CI: 0.08, 0.94).
Contrary to our hypotheses, diet quality has slightly improved and prevalence of food insecurity was reduced in this sample of adults from Quebec during the COVID-19-related early lockdown. These results may be generalizable only to relatively healthy populations.

摘要：
2019年冠状病毒病(COVID-19)相关的早期封锁对人口饮食习惯和粮食不安全的影响尚不清楚。
这项研究的目的是记录在与COVID-19相关的早期封锁期间观察到的饮食质量和粮食不安全的变化。我们假设封锁与整体饮食质量的恶化和粮食不安全的增加有关。
数据来自NutriQuébec的COVID-19子样本，一个基于网络的队列旨在研究魁北克成年人饮食习惯的时间变化，加拿大。参与者在提前封锁之前（2019年6月至2020年2月）和提前封锁期间（2020年4月至5月）完成问卷。包括经过验证的基于网络的24小时召回（n=853）和食品安全问卷（n=922）。主要研究结果是通过健康饮食指数（HEI）-2015年测量的饮食质量的时间变化以及粮食不安全的患病率。
与基线相比，在COVID-19早期封锁期间，HEI-2015略有增加(+1.1点；95%CI：0.6，1.5)，主要是由于全谷物摄入量的小幅改善，绿色和豆类，精制谷物,总蔬菜，总乳制品，海鲜和植物蛋白，加糖,和HEI-2015的总蛋白质分。探索性分析表明，年龄在18-29岁的个体(+3.6分；95%CI：2.4，4.7)，受教育程度较低的参与者（+1.9分；95%CI：1.3，2.6），或肥胖患者(+3.8分;95%CI:2.7,4.8)在HEI-2015中表现出特别重要的增长。早期封锁期间，粮食不安全的患病率从基线时的3.8%降至1.0%(患病率=0.27；95%CI：0.08，0.94)。
与我们的假设相反，在与COVID-19相关的早期封锁期间，魁北克成人样本的饮食质量略有改善，粮食不安全患病率降低。这些结果可能仅适用于相对健康的人群。
