This randomized clinical trial assessed the impact of an early-life liquefied petroleum gas cooking intervention on lung function in Guatemalan children. Among 800 pregnant women, those receiving gas cookstoves showed no significant improvement in prespecified lung function outcomes at age 3. However, exploratory results indicated a lower resistance across frequencies in the intervention group (adjusted difference: -0.31 cm H2O*S/L).
Key findings
- No significant effect on prespecified oscillometry outcomes was observed.
- Exploratory analysis showed lower resistance across frequencies in the intervention group.
- Valid oscillometry data was obtained from 525 out of 750 children.
- 57% of missed tests were due to children's unwillingness to perform measurements.
Why it matters
Understanding the effects of cooking fuel on lung function is crucial, as household air pollution is linked to respiratory diseases. This study provides insights into potential interventions that could improve airway health in children.
