Summary
Asthma mortality rates are high across Latin America, with significant variations between countries. Most deaths occur at home, highlighting a need for greater public health attention to this serious respiratory condition.
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.
