Global Asthma Prevalence – Global Burden of Disease 2021

According to the Global Burden of Disease study 2021, a systematic review and meta-analysis including data from 389 sources for asthma reported that in 2021 there was:

  • an estimated 260 million people with asthma worldwide
  • forecast to reach 275 million people having asthma in 2050
  • age standardised prevalence: 3340 per 100,000 in 2021, a 40% decrease compared to 1990 (5568 per 100,000), and expected to remain stable between 2021 and 2050.

Modifiable risk factors were responsible for 30% of the global asthma DALY burden, particularly high BMI in high-socio-demograhic (SDI) index settings, and occupational asthmagens in low SDI settings.
