In February 2020, a novel coronavirus (SARS-COV2) broke out in Wuhan city of China. The Chinese government decisively imposed nationwide confinement. This study comprised a structured, online questionnaire, based on 40 items inquiring about socio-demographic information and anthropometric data (reporting weight and height), as well as changes in food intake, physical activity, and sleep during the COVID-19 outbreak. Questionnaires were distributed to residents of Jiangsu and other provinces from 29 March to 5 April. A total of 889 respondents were included, aged between 16 and 70 years (61% females). There was a significant increase in total food intake by 9.8% and a slight increase by 29.2% of respondents, and a significant decrease in physical activity by 31.5% and a slight decrease by 23.4% of respondents, especially in snacks and drinks, and outdoor activities. The rate of weight gain in the total population was 30.6% and the average weight gain was 0.5 ± 2.8 kg. The main factors contributing to weight gain were increased food intake and reduced physical activity. Additionally, normal-weight people were more likely to gain weight than people with overweight/obesity during the COVID-19 confinement. This study provided a good warning and educational reference value on lifestyle changes during the COVID-19 confinement.
2020 年 2 月，一种新型冠状病毒（SARS-CoV2）在中国武汉市爆发。中国政府果断实施全国性封城。本研究采用结构化在线问卷，共 40 个项目，询问社会人口统计学信息和人体测量数据（报告体重和身高），以及 COVID-19 爆发期间食物摄入、身体活动和睡眠的变化。问卷于 2020 年 3 月 29 日至 4 月 5 日分发给江苏和其他省份的居民。共纳入 889 名年龄在 16 至 70 岁之间的受访者（61%为女性）。总食物摄入量显著增加 9.8%，有 29.2%的受访者略有增加，身体活动量显著减少 31.5%，有 23.4%的受访者略有减少，尤其是零食和饮料以及户外活动。总人口体重增加率为 30.6%，平均体重增加 0.5±2.8 公斤。导致体重增加的主要因素是食物摄入量增加和身体活动减少。此外，在 COVID-19 封城期间，正常体重人群比超重/肥胖人群更容易增重。本研究为 COVID-19 封城期间的生活方式变化提供了良好的警示和教育参考价值。
