Prevalence of depression, anxiety, and insomnia among healthcare workers during the COVID-19 pandemic: A systematic review and meta-analysis
Open accessAbstract
Background COVID-19 pandemic has the potential to significantly affect the mental health of healthcare workers (HCWs), who stand in the frontline of this crisis. It is, therefore, an immediate priority to monitor rates of mood, sleep and other mental health issues in order to understand mediating factors and inform tailored interventions. The aim of this review is to synthesize and analyze existing evidence on the prevalence of depression, anxiety and insomnia among HCWs during the Covid-19 outbreak.Methods A systematic search of literature databases was conducted up to April 17th, 2020. Two reviewers independently assessed full-text articles according to predefined criteria. Risk of bias for each individual study was assessed and data pooled using random-effects meta-analyses to estimate the prevalence of specific mental health problems. The review protocol is registered in PROSPERO and is available online.Findings Thirteen studies were included in the analysis with a combined total of 33,062 participants. Anxiety was assessed in 12 studies, with a pooled prevalence of 23·2% and depression in 10 studies, with a prevalence rate of 22·8%. A subgroup analysis revealed gender and occupational differences with female HCPs and nurses exhibiting higher rates of affective symptoms compared to male and medical staff respectively. Finally, insomnia prevalence was estimated at 38·9% across 5 studies.Interpretation Early evidence suggests that a considerable proportion of HCWs experience mood and sleep disturbances during this outbreak, stressing the need to establish ways to mitigate mental health risks and adjust interventions under pandemic conditions.

TL;DR
This systematic review and meta-analysis pooled 13 cross-sectional studies of healthcare workers during the COVID-19 pandemic and found substantial pooled prevalence of anxiety, depression, and insomnia. It reports roughly one in four workers with anxiety or depression and about one in three with insomnia, with higher estimates among women and nursing staff.
Key findings
- Pooled prevalence was 23.21% for anxiety (95% CI 17.77–29.13, I² = 99%; 12 studies), 22.8% for depression (95% CI 15.1–31.51, I² = 99.62%; 10 studies), and 34.32% for insomnia (95% CI 27.45–41.54, I² = 98%; 5 studies).
- Subgroup estimates were higher for women than men for anxiety (29.06% vs 20.92%) and depression (26.87% vs 20.34%), and higher for nurses than doctors for anxiety (25.80% vs 21.73%) and depression (30.30% vs 25.37%).
- Mild symptoms were more common than moderate/severe symptoms: anxiety 17.93% vs 6.88%; depression 24.60% vs 16.18%. Scale-specific pooled estimates varied, e.g., GAD-7 anxiety 36.92% vs SAS anxiety 16.47%, and PHQ-9 depression 36.72 vs SDS depression 32.81.
Methods
- The review followed PRISMA and MOOSE guidance and was registered in PROSPERO (CRD42020180313). Searches covered MEDLINE, PubMed, Google Scholar, MedRxiv, and SSRN through April 17, 2020, with no language restrictions, and included cross-sectional studies of healthcare workers in COVID-19-affected areas that used validated measures for depression, anxiety, or insomnia.
- The meta-analysis included 13 cross-sectional studies with 33,062 participants; 12 were conducted in China (2 in Wuhan) and 1 in Singapore. Median study size was 1,563 (range 134–11,118), median male representation was 18%, and median questionnaire participation was 85.3%.
- Pooled prevalence was estimated with a random-effects model in MetaXL using double arcsine transformation. Subgroup analyses examined gender, rating scales, symptom severity, and professional group; sensitivity analyses excluded each study in turn. Study quality was assessed with a modified Newcastle-Ottawa scale.
Limitations
- Stated in the paper: heterogeneity was high across studies because of different assessment scales and cut-offs; some studies may have sampled overlapping populations from the same region or country; most studies were from China, limiting generalizability; all included studies were cross-sectional, so long-term mental health effects remain unknown; and the number of available studies was relatively small early in the pandemic.
- Evident from the text: the very high I² values (often near 99%) indicate substantial unexplained between-study variability, and the inclusion of preprints means some data may not have been peer-reviewed.

“To our knowledge, this is the first systematic review and meta-analysis to examine the pooled prevalence of depression, anxiety and insomnia on HCW during the COVID-19 outbreak.”
The authors state this as an assumption.
One true effect size cannot be assumed across studies due to different patient populations, regions, and assessment methods.
“Due to the different patient populations, regions, and assessment methods across studies, one true effect size cannot be assumed; therefore, a random effects model (DerSimonian & Laird) was used to extract the pooled prevalence.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
