| Abstract|| |
Aim: Present systematic review and meta-analysis examined the burden of psychological reactions predominantly anxiety, depression, stress, and insomnia during the novel COVID-19 pandemic phase among the frontline healthcare, nonfrontline healthcare, and general population. Material and Methods: PubMed, EMBASE, and SCOPUS were searched for studies between January 1, 2020, and May 25, 2020. Brief protocol of the systematic review was registered with the PROSPERO database, (CRD42020186229). Any study that reported the burden of at least one of psychological reactions including anxiety or depression or stress or insomnia was eligible. Heterogeneity was assessed using I2 statistic and results were synthesized using random-effect meta-analysis. Results: Out of 49 eligible studies, 41 databases from 37 studies reported anxiety, 39 databases (35 studies) reported depression, 20 studies reported stress and 12 databases from 11 studies reported insomnia. The overall prevalence for anxiety, depression, stress, and insomnia was 26.3%, 25.9%, 26.2%, and 31.3%, respectively. Prevalence of anxiety, depression, stress, and insomnia were found highest among the frontline healthcare as compared to general healthcare workers and the general population. Conclusion: Anxiety, depression, stress, and insomnia were more prevalent among frontline health-care workers compared to general. Such increased prevalence is prompting toward the global mental health emergency. Therefore, a call of urgent attention and pan-region effective mental-health intervention are required to mitigate these psychological reactions.

| Introduction|| |
Novel pneumonia caused by the coronavirus disease (COVID-19) has emerged in the Chinese city of Wuhan (Hubei province) in late December 2019 and spread rapidly nationwide and all over the world. The World Health Organization declared an international public health emergency on January 30, 2020. The virus spread in nearly 213 countries and territories with 66.2 million confirm cases, 1.5 million confirmed deaths, and 45.8 million recovered according to the global data reported by the Worldometer on December 4, 2020.
During this global pandemic fear of rapid infection spread, falling sick and dying social isolation, and extended quarantine are expected to influence mental health. Fear related to shortages of vaccine, critical care support fear of financial crisis, joblessness, and frozen economy, during the lockdown, may play the lead role to increase the burden of mental health illness. Such psychological burden had been reported among the COVID-19 patients, healthcare personnel, medical students, and older as well as the general population.,,
During the Ebola outbreak in West Africa, the greater number of healthy people was mentally traumatized compare to the number of infected people and remained longer. Such historical devastation prompts toward another global mental health challenge during the COVID-19 pandemic. Therefore, it is important to understand the increased burdens of mental health outcomes as a consequence of the COVID-19 pandemic.
Estimates of psychological burdens vary across the studies. Such variations might occur because these studies carried on different population, with varying sample sizes and dealt with different scales of mental-illness assessment.
In this study, a systematic review and meta-analysis was conducted to assess the burden of mental health outcomes predominantly on the prevalence of anxiety, depression, stress, and insomnia during COVID-19 global emergency among three group of the population, i.e. frontline health-care workers (FHW), nonFHWs (NFHW) and the general population who are not healthcare workers.
| Material and Methods|| |
Protocol of the present systematic review was registered with the PROSPERO database (Registration Number: CRD42020186229). The present systematic review manuscript is designed as per the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis.
A systematic literature search in electronic databases including Embase, PubMed, and Scopus between January 1, 2020, and May 25, 2020, was used to find the eligible studies. The used search term was “(COVID-19 OR SARS-CoV-2 OR 2019-nCoV OR coronavirus) AND (Depression OR Anxiety OR stress OR insomnia OR “psychological distress”OR “Psychiatric illness” OR “Mental Health”).” In addition, a supplementary search was conducted using Google Scholar. All the published or unpublished studies assessing mental illness using scientific rating scale and reporting overall prevalence/graded prevalence (mild, moderate, and severe) of psychological anxiety or depression or stress or insomnia as an impact of COVID-19 using original data were considered eligible.
All the retrieved articles first were screened based on title and abstract and then reviewed for the full text of potentially eligible articles independently and in duplicate by both authors (B. T. and M. P.). Data regarding study identification, population, sample size, the prevalence of anxiety, depression, stress, and insomnia (or categorized on the graded scale like normal, mild, moderate, and severe), scale for outcome measurement and quality-related variables were extracted by both authors independently on the preprepared form. All the discrepancies were resolved by discussion.
The modified Newcastle-Ottawa Quality Assessment Scale was used to assess the methodological quality for cross-sectional studies. Since the present meta-analysis focused only prevalence of mental health outcomes, the quality of the studies was judged based on four criteria only including representative sample, adequate sample size, low nonresponse rate, and objective outcome measurement. Hence, the range of quality score was 0–5. Quality scores were categorized as 4/5 = Good, 3 = Average, and 2/0 = Poor. Both the reviewer (BT and MP) independently assessed the quality of eligible studies.
Proportion of psychological stress, anxiety, depression, and insomnia as overall, as well as on the graded scale of mild, moderate, and severe were pooled using fixed-effect inverse variance method or DerSimonianand Liard random effect method depending on heterogeneity measured using I2 statistic. Subgroup analysis was performed based on type of population, i. e., FHW, NFHW, and other general.
we used egger's test to assess publication bias. The quality of our evidence was graded using Grading of Recommendations, Assessment, Development, and Evaluations approach.
| Results|| |
A total of 2337 unique studies were identified by searching the databases. Out of these, 111 studies qualified for full-text review [Figure 1]. Of these 111 studies, 63 were excluded because of various reasons mentioned in [Figure 1].

A total of 49 studies comprised 55 datasets of the diverse population for 147142 individuals were included. Of these 55 datasets, 32 datasets involving 123650 individuals reported mental health burden for the general population.,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,; 15 datasets reported mental health of 8335 frontline healthcare workers,,,,,,,,,,,,,, and eight datasets reported for 12,462 nonfrontline health-care workers.,,,,,, Study level characteristics are presented in Supplementary [Table S1].
Group-wise data were extracted for the studies which reported mental health for more than group to facilitate subgroup comparison.,,,,
The majority of the studies (32 out of 49) were conducted in China. Among rest of the 17 studies, four studies were conducted in Italy,,,, three in Spain,,, two , from Iran, two from Turkey, and one-one study was conducted in Israel, Singapore, Greece, France, USA, and England. Further, the study conducted in Singapore included data for India as well as Singapore. Hence, country-level data were extracted for this study.
The severity of psychological health parameters were reported by 18 studies (2, 3, 9, 14, 18, 24, 28, 32, 34, 38, 42, 43, 45, 46, 48, 49, 51, 54); 17 for anxiety (2, 3, 9, 14, 18, 24, 28, 32, 34, 38, 42, 43, 45, 46, 48, 51, 54)); 11 for depression (3, 9, 14, 18, 28, 32, 34, 38, 43, 46, 51); five for stress (3, 14, 28, 32, 46) and four for insomnia (9, 32, 46, 49).
Out of the total 49 included studies, 30 studies had “Good” quality (11 studies had score 5 and 19 studies had score 4), 18 studies were grades as “average” quality with score 3 and one study had poor quality with score 2 [Supplementary Table S2]. Most of the eligible studies collected their data using social media platform. These studies could include data for social media users not from any well-defined population and hence, these studies did not have representative sample. Formal sample size calculation or power assessment was done only for two studies. Further, we found a wide heterogeneity in the reported results. These facts lower the confidence in our graded evidence. The moderate grade for evidence of anxiety and depression suggests that further studies may less likely to change the current evidence [Table S3]. We could not find significant publication bias for any of the outcomes.
Overall pooled prevalence of anxiety was 26.3% (95% confidence interval [CI]: 22.4%–30.2%) which was observed relatively higher among the FHWs (27.2%; 95% CI: 18.1%–36.3%) followed by NFHW (26.9%; 95% CI: 19.5%–34.0%) and general population (25.9%; 95% CI: 20.5%–31.2%) [Figure 2]a. Meta-analysis of prevalence on severity scale based on 17 available studies resulted that most of the individuals had mild anxiety (15.2%; 95% CI: 10.7%–9.6%). Moderate anxiety (7.5%; 95% CI: 4.5%–10.6%) and severe anxiety (5.5%; 95% CI: 3.3%–7.8%) were observed among very few individuals [Figure 3]a. However, moderate and severe anxiety were observed highest among the general population.

A total of 25.9% (95% CI: 21.4%–30.5%) were identified to have depression [Figure 2]b. This prevalence was found highest among FHWs (32.1%; 95% CI: 18.0%–46.2%) followed by general population (25.9%; 95% CI: 21.4%–30.5%) and NFHW (15.7%; 95% CI: 11.3%–20.1%) [Figure 2]b. On the severity scale of depression, 19% of the individuals had mild depression, 7.0% had moderate, and very few (4.8%) were severe cases [Figure 3]b. Further, depression burden was observed highest among the frontline health workers in all the three groups of mild, moderate, and severe [Figure 3]b.
[Figure 2]c showed the overall stress prevalence as 26.2% (95% CI: 18.2%–34.2%). Our pooled effect of stress prevalence was found highest among the FHWs (55.6%; 95% CI: 0.36%–100%) followed by general population (23.9%; 95% CI: 15.9%–32.0%) and NFHW (7.0%; 95% CI: 3.1%–10.9%). Based on five reported studies, pooled stress prevalence resulted into 18.3% mild, 9.8% moderate, and only 4.4% severe stress levels [Figure 3]c.
Overall insomnia burden was found as 31.3% (95% CI: 22.9%–39.7%) [Figure 2]d. Pooled effect of insomnia prevalence among the general population was observed as 27.2% (95% CI: 16.3%–38.2%), a lower than the prevalence among FHWs (34.4%; 95% CI: 32.5%–36.3%) and NFHWs (34.0%; 95% CI: 32.5%–35.4%) [Figure 2]d. Further on the severity graded scale, mild, moderate, and severe level of insomnia were observed as 18.4%, 11.4%, and 1.1%, respectively [Figure 3]d.
| Discussion|| |
This systematic review and meta-analysis were based on the data extracted from 49 different studies. Most of these studies were conducted in China, the country where COVID-19 emerged, although studies conducted in Taiwan, Vietnam, Singapore, Italy, Israel, Iran, Greece, Spain, USA, Turkey, and England were also included. Studies varied in sample size from 57 to 52730. One largest study incorporated information for multiple countries such as China, Macau, Hong Kong, and Taiwan. Most of the studies reported prevalence of anxiety and depression and very few reported for stress and insomnia. Various scales were used to measure these outcomes but most of the variability found for stress outcome. All the included studies were performed with cross-sectional design and majority of these studies were based on web-based survey and therefore lacking random sampling method of data collection. Grade approach suggested there is moderate level of confidence in our finding for anxiety, depression, and insomnia but low level of confidence for stress.
The burden of anxiety, depression, stress, and insomnia were found highest among the FHWs. We also found that after FHWs, the burden of depression and stress was highest among the general population, and the burden of anxiety and insomnia was highest among the NFHWs.
During this pandemic, a handful of reviews and meta-analyses on the prevalence of mental health outcomes were reported among the healthcare workers and general population. However, all these reviews are based on the small number of studies, majorly based on Chinese studies and focusing on a particular population. In addition to the Chinese studies, our review attempted to include the most updated global studies targeting wide range of the population. We also attempted the overall prevalence based on the graded scale of severity for all the outcomes [Table S3]. The burden of the mild stage was observed as highest followed by moderate and severe stages for all four outcomes. Similar exploration on graded scale was also attempted among the various subpopulations, i.e. FHWs, NFHWs, general population, COVID-19-infected patients, and quarantine people.
According to the recent report of Our World in Data, the prevalence of anxiety disorder and depression was observed as 3.8% and 3.4%, respectively. Our finding suggests how the psychological pressure during the pandemic public health crisis increased the mental health burden. According to a recent meta-analysis report in 2017, insomnia prevalence in the general population of China observed as 15% which was far lower than the insomnia prevalence among the general population observed in our study during the COVID-19 pandemic. Similarly, the global prevalence of posttraumatic stress disorder was reported as 15.3%. These reports and our finding suggests that the burden of insomnia and stress in the general population, increased almost to double, was certainly a consequences of COVID-19 fear.
During the crucial public health emergency of COVID-19, the frontlines healthcare professionals feel fear of getting sick and spreading the infection to their families, other patients, and coworkers. Our comparative analysis results show that the prevalence of all four mental health outcomes was significantly high among the frontline healthcare professionals as compared to the general population. These findings suggest the positive correlation between the management of COVID-19 patients by healthcare professionals and increased psychological responses among them.
Although surveys and studies in the current COVID-19 emergency confirmed new psychological responses might have accelerated the existing burden of mental health outcome during the COVID-19 outbreak, this burden may further increase and may stay longer depending on the time required to control the infection. Studies on the risk factors associated with the various mental health problems is need to be explored to manage with evidence-based interventions. Some of the individual-level risk factors may also get effected by the country-level parameters such as countries' policies on virus prevention at the community level, healthcare infrastructure, climatic condition, concurrent burden of COVID-19 and its spreading speed. Policymakers need to make effective decisions about where to focus their efforts to mitigate such burden.
| Conclusion|| |
Overall COVID-19 pandemic has been impacting on the mental health of the worldwide general population, but frontline healthcare warriors had shown relatively having more stress, anxiety, depression, and insomnia as compared to general healthcare workers and general. However, mostly, these mental ailments are mild to moderate in severity. Our finding suggests that the new psychological reactions and sudden increment in the burden of mental health outcomes during the COVID-19 pandemic is prompting toward another global health emergency. Therefore, a call of urgent attention and pan-region intervention are required to manage the current burden of mental health outcomes and further for future.
