This systematic review and meta-analysis examined the relationship between air pollution and respiratory morbidity in Africa, analyzing data from thirteen studies across ten countries. The findings revealed that indoor PM2.5 levels in biomass-using homes ranged from 96 to 177 µg/m³, with ambient PM2.5 reaching 259 µg/m³, indicating significant health risks, particularly for young children and those with pre-existing conditions.
Key findings
- Indoor PM2.5 levels in biomass-using homes ranged from 96 to 177 µg/m³.
- Ambient PM2.5 levels reached 259 µg/m³, exceeding WHO guidelines.
- Nitrogen oxides were linked to reduced lung function in children.
- Household air pollution increased risks of under-five mortality and low birthweight.
Why it matters
Understanding the impact of air pollution on respiratory health is crucial for developing effective public health strategies. The findings underscore the need for interventions to reduce exposure, particularly in vulnerable populations such as young children.
