Changes in Dietary Pattern and Lifestyle in Adults during Lockdown Due to the COVID- 19 Pandemic: A Systematic Review Protocol

The purpose of this protocol is to demonstrate a systematic process for reviewing the existing literature on dietary and lifestyle changes during the COVID-19 pandemic lockdown. The research design is a systematic review using electronic bibliographic databases (PubMed, Science Direct, Google Scholar, DOAJ, CrossRef and ProQuest) and includes a list of reference articles. At least two reviewers will independently screen, extract and select studies using the PRISMA flow chart which will include information on demographics, diet and lifestyle changes, and their impact on health according to the inclusion and exclusion criteria that have been established. Quality assessment of articles that have been screened using JBI guidelines. A qualitative synthesis analysis will be carried out to summarize the research results from each article. This protocol forms the basis for a structured plan to conduct a systematic review that will present evidence and summarize research results related to changes in diet and lifestyle due to the COVID-19 lockdown and their impact on nutritional and health status. This information is important for health promotion policies and the development of dietary and lifestyle guidelines and food security during the pandemic and beyond.
