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.
Design: 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.
Participants: 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.
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.
Conclusion and implication: 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.
