The COVID-19 pandemic introduced risks and challenges to global food and nutrition security. In this paper, we examine the impact of the COVID-19 pandemic on the nutritional intake of China’s rural residents using panel data and a fixed effects model. The data were collected in 2019 and 2020 and covered nine provinces and 2631 households in rural China. The results reveal that an increase of 100 confirmed cases in a county resulted in a 1.30% (p < 0.01), 1.42% (p < 0.01), 1.65% (p < 0.01), and 1.15% (p < 0.01) decrease in per capita intake of dietary energy, carbohydrates, fats, and proteins, respectively. Moreover, the COVID-19 pandemic had a significant and negative effect on dietary macronutrient intake in the low-income group at the 5% level of significance. Our study indicates that the potential insufficient nutrition situation, nutritional imbalance, and dietary imbalance of low-income rural residents should be addressed appropriately.
新冠疫情给全球粮食和营养安全带来了风险和挑战。本文利用面板数据和固定效应模型，考察了新冠疫情对中国农村居民营养摄入的影响。数据采集于 2019 年和 2020 年，涵盖了中国 9 个省份的 2631 户农村家庭。结果表明，一个县每增加 100 例确诊病例，居民人均摄入的膳食能量、碳水化合物、脂肪和蛋白质将分别减少 1.30%（p<0.01）、1.42%（p<0.01）、1.65%（p<0.01）和 1.15%（p<0.01）。此外，新冠疫情对低收入群体的膳食宏量营养素摄入也有显著的负面影响，在 5%的显著水平上。本研究表明，应适当关注农村低收入居民潜在的营养不足、营养失衡和膳食失衡问题。
