Global, regional, and national burden of fungal skin diseases in 204 countries and territories from 1990 to 2021: An analysis of the global burden of disease study 2021

Abstract

AbstractBackgroundFungal skin diseases are common skin diseases with a heterogeneous distribution worldwide.ObjectivesThis study aimed to analyse the spatiotemporal trends in the burden of fungal skin diseases at global, regional, and national levels from 1990 to 2021.MethodsBased on the data obtained from the Global Burden of Disease Study (GBD) 2021, we described the incident cases, prevalent cases, number of disability‐adjusted life years (DALYs), and corresponding age‐standardised rates (ASRs) for fungal skin diseases in 1990 and 2021 by sex, age, socio‐demographic index (SDI), 21 GBD regions, and 204 countries and territories. We used Joinpoint regression analysis to assess the temporal trends in burden of fungal skin diseases during 1990 to 2021. Spearman's rank test was used to analyse the relationship between disease burden and potential factors.ResultsFrom 1990 to 2021, the incident cases, prevalent cases, and DALYs for fungal skin diseases worldwide increased by 67.93%, 67.73%, and 66.77%, respectively. Globally, the age‐standardised incidence rate (ASIR), age‐standardised prevalence rate (ASPR), and age‐standardised DALYs rate (ASDR) for fungal skin diseases in 2021 were 21668.40 per 100,000 population (95% UI: 19601.19–23729.17), 7789.55 per 100,000 population (95% UI: 7059.28–8583.54), and 43.39 per 100,000 population (95% UI: 17.79–89.10), respectively. Between 1990 and 2021, the ASIR, ASPR, and ASDR for fungal skin diseases have modestly increased, with AAPC of 11.71% (95% confidence interval [CI]: 11.03%–12.39%), 19.24% (95% CI: 18.12%–20.36%), and 20.25% (95% CI: 19.33%–21.18%), respectively. Males experienced a higher burden of fungal skin diseases than females. The incident cases, prevalent cases, and DALYs for fungal skin diseases were highest at the age of 5–9, while the ASRs were highest among the elderly. At national level, the highest ASRs were observed in Nigeria, Ethiopia, and Mali. Overall, SDI was negatively correlated with the ASRs, whereas Global Land‐Ocean Temperature Index (GLOTI) was remarkably positively correlated with the burden of fungal skin diseases.ConclusionsBetween 1990 and 2021, the global burden of fungal skin diseases has increased, causing a high disease burden worldwide, particularly in underdeveloped regions and among vulnerable population such as children and the elderly. With global warming and aging of the population, the burden of fungal skin diseases may continue to increase in the future. Targeted and specific measures should be taken to address these disparities and the ongoing burden of fungal skin diseases.
