To examine the evidence that the dietary quality of children changed between the period preceding the COVID-19 pandemic and the first year during the pandemic.
A systematic review of the evidence for dietary changes occurring as a result of the pandemic-related restrictions, in Part I of this article, yielded 38 original research articles. These articles had conflicting results, some describing improvements in overall quality and some describing deteriorations. As a whole the studies were characterized by a low study quality, and children were poorly represented. Taken together, these studies do not provide enough evidence to draw conclusions about whether dietary habits changed or not as a result of the pandemic. However, in a wider, narrative review of the psychosocial changes occurring as a result of the COVID-19 pandemic, and the known associations of these factors with a dietary intake in Part II, we conclude that there is a reason to expect that the dietary quality of children might have been adversely affected by the COVID-19 pandemic. One the one hand, the literature fails to provide conclusive evidence on changes in the dietary quality of children resulting from the COVID-19 pandemic. On the other hand, the broader literature supports the hypothesis that children's dietary quality will have declined during the pandemic. Taken together, we urgently need more high-quality research on children's changes in dietary intake occurring over the pandemic. This will provide important information on whether any potential long-term consequences of such changes, if they exist, need to be examined and ameliorated.
研究 COVID-19 大流行前时期和大流行第一年期间儿童饮食质量变化的证据。
本文第一部分对大流行相关限制导致饮食变化的证据进行了系统审查，共检索到 38 篇原始研究文章。这些文章的结果相互矛盾，有些描述了整体质量的改善，有些则描述了质量的恶化。总的来说，这些研究的研究质量较低，且代表性较差。综合来看，这些研究并没有提供足够的证据来得出大流行是否导致饮食习惯发生变化的结论。然而，在第二部分对 COVID-19 大流行导致的心理社会变化以及这些因素与饮食摄入的已知关联进行的更广泛的叙述性综述中，我们得出结论，有理由认为儿童的饮食质量可能受到 COVID-19 大流行的不利影响。一方面，文献未能提供确凿的证据证明 COVID-19 大流行导致儿童饮食质量发生变化。另一方面，更广泛的文献支持这样一种假设，即大流行期间儿童的饮食质量会下降。综上所述，我们迫切需要更多关于大流行期间儿童饮食摄入变化的高质量研究。这将提供有关此类变化是否存在任何潜在的长期后果以及是否需要进行检查和改善的重要信息。
