Area of Science:

  • Epidemiology
  • Pulmonology
  • Public Health

Background:

  • Asthma mortality data in Latin America is scarce, hindering effective public health strategies.
  • The Latin American Society of Allergy and Immunology initiated a study to address this data gap.
  • Asthma is a significant global health issue affecting all ages, often underestimated by health ministries.

Purpose of the Study:

  • To analyze asthma mortality rates across multiple Latin American countries.
  • To identify demographic and geographic factors associated with asthma deaths.
  • To provide epidemiological data to advocate for increased attention to asthma management.

Main Methods:

  • A uniform protocol was applied across 11 participating Latin American countries.
  • Asthma mortality rates were analyzed using age-adjusted (5-34 years) and total death rates.

  • Data on sex, location of death (home vs. hospital), and seasonality were collected and analyzed.

    • Main Results:

    • High asthma mortality rates were observed in Uruguay and Mexico, with lower rates in Paraguay and Colombia.
    • Age-adjusted mortality rates (5-34 years) were highest in Costa Rica and lowest in Chile.
    • A female predominance in asthma deaths was noted (51.8%), and deaths predominantly occurred at home in most countries, particularly during winter in southern regions.

    Conclusions:

    • Asthma mortality rates in Latin America are substantial and warrant urgent public health intervention.
    • Epidemiological data is crucial for convincing health ministries of the severity of asthma.
    • Further studies are needed to fully understand and combat asthma mortality in the region.
