“…Our analysis included 121 studies to calculate the pooled global prevalence of seborrheic dermatitis. These studies encompassed 1 260 163 participants with clinician-diagnosed seborrheic dermatitis, uncovering an overall pooled prevalence of 4.38% (95% CI, 3.58%-5.17%) with an IQR of 1.55% to 5.45%, alongside significant statistical heterogeneity ( I 2 = 99.94%; df = 120; Q = 38 414.25) (Table, Figure 2, Figure 3). Sensitivity analyses confirmed the stability of this prevalence estimate, showing minimal variation in the sequential exclusion of individual studies.…”

ImportanceSeborrheic dermatitis is a prevalent chronic inflammatory skin disease, yet its global prevalence, pathogenesis, and epidemiology remain inadequately defined.ObjectiveTo provide a detailed estimation of the global prevalence of seborrheic dermatitis, analyze demographic variations, and explore differences in various settings.Data SourcesEmbase, PubMed, Scopus, and Cochrane Database of Systematic Reviews were searched from inception through October 2023.Study SelectionOriginal investigations on seborrheic dermatitis prevalence were included after duplicate screening of titles, abstracts, and full articles, including only studies with clinician-diagnosed cases.Data Extraction and SynthesisFollowing PRISMA guidelines, data were extracted and quality was assessed independently by multiple reviewers. A random-effects model using restricted maximum likelihood was used for meta-analysis and subgroup analyses.Main Outcome and MeasureThe primary outcome was the pooled estimate of global seborrheic dermatitis prevalence.ResultsFrom 1574 identified articles, 121 studies were included, encompassing 1 260 163 individuals and revealing a pooled global seborrheic dermatitis prevalence of 4.38% (95% CI, 3.58%-5.17%), with significant heterogeneity (I2 = 99.94%). Subgroup analyses showed variations by age, with a higher prevalence in adults (5.64% [95% CI, 4.01%-7.27%]) compared to children (3.70% [95% CI, 2.69%-4.80%]) and neonates (0.23% [95% CI, 0.04%-0.43%]). Geographic analyses indicated variability, with the highest prevalence in South Africa (8.82% [95% CI, 3.00%-14.64%]) and the lowest in India (2.62% [95% CI, 1.33%-3.92%]).Conclusions and RelevanceThis comprehensive meta-analysis provides a detailed estimation of the global prevalence of seborrheic dermatitis, highlighting significant variability across different demographics and settings.
