Global Burden of Bacterial Skin Diseases: A Systematic Analysis Combined With Sociodemographic Index, 1990-2019

Background: The latest incidence and disability-adjusted life-years (DALYs) of major bacterial skin diseases (BSD) and their relationship with socioeconomic are not readily available.

Objective: Describe the global age-standardized incidence and DALYs rates of BSD and analyze their relationship with socioeconomic.

Methods: All data were obtained from Global Burden of Disease (GBD) 2019 database. The correlation between BSD and socioeconomic development status was analyzed.

Results: The age-standardized incidence and age-standardized DALYs rate of BSD are: 169.72 million [165.28-175.44] and 0.41 million [0.33-0.48]. Of the two main BSD, pyoderma cause significantly much heavier burden than cellulitis. The change of age-standardized incidence (7.38% [7.06-7.67]) and DALYs (-10.27% [-25.65 to 25.45]) rate of BSD presented an upward or downward trend from 1990 to 2019. The highest burden was in the low-middle sociodemographic index (SDI) area while the area with the lowest burden was recorded in the high-middle SDI area in 2019.

Limitations: GBD 2019 data of BSD are derived from estimation and mathematical modeling.

Conclusion: The burden of BSD is related to socioeconomic development status. The results based on GBD2019 data may benefit policymakers in guiding priority-setting decisions for the global burden of BSD.
