The outbreak of novel coronavirus (COVID-19) provided an opportunity to undertake an online survey to study the relationships between body weight changes with changes in physical activity and lifestyle during an unusual event of forced isolation, or quarantine.
We distributed an electronic questionnaire using the popular social application WeChat to adults from any province of China except Hubei Province, the epicenter of the outbreak. The questionnaire asked for demographic information, body weight, physical activity, and lifestyle factors before and during the quarantine.
Of 376 questionnaires returned, 339 were valid (90.2%). During the period of semi-lockdown, both females and males with BMI <24 gained weight, males with BMI ≥24 lost weight, and females with BMI ≥24 gained weight. The average steps per day and the average moderate or vigorous-intensity exercise declined significantly for both males and females during the semi-lockdown. Changes in body weight inversely correlated with changes in steps per day and moderate or vigorous-intensity exercise during the quarantine.
Normal weight individuals, who are not normally troubled by overweight or obesity, had less awareness of weight gain than people with a BMI ≥ 24. Under the conditions of the semi-lockdown, they tended to gain weight.
新型冠状病毒（COVID-19）疫情提供了一个机会，可开展一项在线调查，以研究在强制隔离或检疫这一特殊事件期间体重变化与身体活动及生活方式变化之间的关系。
我们通过流行的社交应用微信向除疫情中心湖北省以外的中国任何省份的成年人发放了一份电子问卷。问卷询问了隔离前和隔离期间的人口统计学信息、体重、身体活动及生活方式因素。
在回收的376份问卷中，339份有效（90.2%）。在半封锁期间，BMI<24的男性和女性体重均增加，BMI≥24的男性体重减轻，BMI≥24的女性体重增加。在半封锁期间，男性和女性的日均步数以及中度或剧烈强度运动均显著下降。隔离期间体重变化与日均步数以及中度或剧烈强度运动的变化呈负相关。
体重正常、通常不受超重或肥胖困扰的个体，对体重增加的意识低于BMI≥24的人群。在半封锁条件下，他们往往会体重增加。
