Association between COVID-19 and anxiety during social isolation: A systematic review

BACKGROUND: The uncertainties about coronavirus disease 2019 (COVID-19), the change in routine, lifestyles and the reduction of physical contact can cause stress, anxiety, emotional overload, poor sleep and even physical health complications. AIM: To evaluate the scientific publications available on the relationship between COVID-19 and anxiety experienced in the general population, during the period of social isolation, adopted by governmental organizations and public health policymakers as a measure to contain the spread of cases. METHODS: A literature search was performed systematically exploring the PubMed and Medline databases using the following terms classified as MeSH descriptors: (“anxiety” AND “pandemic” AND “COVID-19”). For the search, in the Biblioteca Virtual em Saúde – BVS, Science.gov, Web of Science and National Library platforms, the following keywords were used: ("anxiety" AND "coronavirus" AND "social isolation"). Thirty-seven peer-reviewed articles were found. PRISMA and the Downs & Black checklist were used for qualitative evaluation. RESULTS: After applying the inclusion criteria, seven (n = 7) original scientific articles were selected. The collated evidence demonstrated increased levels of symptoms of anxiety and depression during the period of social isolation. The population between 21 to 40 years was most affected. The risk of severe depression was twice as high at the epicenter of the pandemic. Sleep quality was significantly impaired. Questions about politics, religion, and consumption of products from China were found to generate fear and anticipate probable changes in the pattern of post-pandemic consumption. Social isolation exacerbated feelings of extreme hopelessness, sadness, loneliness and suicidal ideation. CONCLUSION: We conclude that there is a potential relationship between social isolation during the COVID-19 pandemic and symptoms of anxiety. It is important to note that the direct and indirect costs of not identifying the detrimental effects of this phenomenon and neglecting strategies for intervention could lead to a significant psychological burden on society in several aspects after social isolation.
