This study aimed to explore food and nutrition related concerns during the post-lockdown period and their impacts on food shopping, preparation, and eating behaviors.
A cross-sectional study was conducted through online questionnaire. We collected data on food and nutrition related concerns, socio-demographic characteristics, and changes in dietary behaviors.
A total of 2267 responses were received from people living in 31 provinces across mainland China and 1994 participants were included in the final analysis.
Linear and multinomial logistic regression analyses were performed to evaluate the association among food and nutrition related concerns, socio-demographic factors, and dietary behaviors Results: About 56% of participants reported moderate to high levels of concerns related to food and nutrition. Contracting the virus when dining out or through contaminated foods were the top two concerns, followed by overnutrition. Higher levels of concerns were found among people who were older, overweight, or obese, having lower income and education, and living in urban areas, or whose family contained vulnerable individuals. Compared with the pre-COVID-19 period, people who were more concerned about food and nutrition were more likely to report changes in their food purchases and consumption; they were also more likely to eat from individual plates, using serving chopsticks, and separating plates and utensils for raw and cooked foods during the post COVID-19 lockdown period.
Food and nutrition related concerns during the post-lockdown period were prevalent and associated with changes in dietary behaviors. Preventative policies and nutritional guidance should be developed to address these concerns in order to reduce inappropriate dietary behaviors amid public health crises.
本研究旨在探讨解封后与食物和营养相关的担忧及其对食品采购、准备和饮食行为的影响。
通过在线问卷进行横断面研究。我们收集了与食物和营养相关的担忧、社会人口学特征以及饮食行为变化的数据。
共收到来自中国大陆31个省份居民的2267份回复，最终分析纳入1994名参与者。
进行线性和多项逻辑回归分析，以评估与食物和营养相关的担忧、社会人口学因素和饮食行为之间的关联。结果：约56%的参与者报告对食物和营养有中度至高程度的担忧。外出就餐或通过受污染食物感染病毒是最主要的两大担忧，其次是营养过剩。在年龄较大、超重或肥胖、收入和教育水平较低、居住在城市地区或家庭中有弱势群体的人群中，担忧程度较高。与新冠疫情前相比，对食物和营养更为担忧的人更有可能报告其食物购买和消费的变化；在新冠疫情解封后，他们也更有可能使用个人餐盘、使用公筷，并将生熟食物的餐盘和餐具分开。
解封后与食物和营养相关的担忧普遍存在，并与饮食行为的变化有关。应制定预防政策和营养指导，以解决这些担忧，从而减少公共卫生危机期间不适当的饮食行为。
