Epidemiological Trends in Alopecia Areata at the Global, Regional, and National Levels.

ABSTRACT:

Background

No comprehensive studies have been published on the global burden of alopecia areata since 2010.

Objective

We aimed to measure the global, regional, and national incidence of alopecia areata and disability-adjusted life-years (DALYs) by age, sex, and socio-demographic index (SDI) value from 1990 to 2019.

Methods

Data were extracted from the Global Burden of Disease Study 2019. Estimated annual percentage changes (EAPCs) were calculated to quantify temporal trends in the age-standardized rates of alopecia areata incidence and DALYs. The correlations between EAPCs in the age-standardized rates and SDI values were also analyzed.

Results

From 1990 to 2019, the alopecia areata incidence number and the associated number of DALYs increased globally by 49.14
