This study seeks to empirically investigate how the changing eating habits affect health habits within three countries with entirely different cultures and diets to understand to what extent the pandemic may be responsible for these changes.
Specifically, a questionnaire was conducted in China, Portugal and Turkey in early 2021. A series of statistical analyses were performed to identify how changes in individuals' eating habits have influenced their diets, considering the pandemic context and the varying cultural contexts where this research was performed.
A structured questionnaire form was developed and uploaded to an online platform with unique links for automatic distribution to respondents in each country. Data for the main survey were gathered between 3 January and 1 February 2021.
Using snowball sampling, the authors leveraged their social networks by asking friends and colleagues to distribute the survey to potentially interested individuals. This distribution was stratified accordingly to the distribution of the population. The authors ultimately collected 319 useable surveys from China, 351 from Portugal and 449 from Turkey.
The pandemic inspired healthier food habits, mostly because people have additional time to cook, shop differently for food and spend more money on groceries.
The study suggests that aside from cultural values and dietary habits, the available time and the fear of the pandemic most explained the new eating habits. Several implications are provided for researchers and overall society in these three countries.
本研究旨在通过实证研究，了解三个文化和饮食完全不同的国家饮食习惯的变化如何影响健康习惯，以了解疫情在多大程度上导致了这些变化。
具体而言，2021 年初在中国、葡萄牙和土耳其进行了问卷调查。进行了一系列统计分析，以确定在考虑到疫情背景和进行研究的不同文化背景下，个体饮食习惯的变化如何影响其饮食。
制定了一份结构化的问卷表格，并上传到一个在线平台上，每个国家都有独特的链接供自动分发给受访者。主要调查的数据于 2021 年 1 月 3 日至 2 月 1 日期间收集。
作者利用雪球抽样法，通过请朋友和同事向可能感兴趣的个人分发调查，利用他们的社交网络。这种分发是根据人口分布进行分层的。最终，作者从中国收集了 319 份有效调查，从葡萄牙收集了 351 份，从土耳其收集了 449 份。
疫情激发了更健康的饮食习惯，主要是因为人们有更多的时间做饭、购买不同的食物和在杂货上花费更多的钱。
该研究表明，除了文化价值观和饮食习惯外，可用时间和对疫情的恐惧最能解释新的饮食习惯。本研究为这三个国家的研究人员和整个社会提供了一些启示。
