Exposure Contrasts of Women Aged 40–79 Years during the Household Air Pollution Intervention Network Randomized Controlled Trial
Wenlu Ye e outros, 2024 · Environmental Science & Technology
Providing an LPG cookstove and free fuel refills reduced older women's personal PM2.5 exposure by 59% relative to biomass-using controls.

Results > Modeling Results; Table 3, row 'comparison of changes', column '% decrease in PM2.5 exposure'
The three modeling approaches yield similar estimated percent reduction in PM2.5 exposure due to the intervention: 59% (95% CI: 55%, 63%) for the “between groups” approach; 67% (95% CI: 63%, 71%) for the “before and after” approach; and 59% (95% CI: 51%, 65%) for the “comparison of changes” approach (Table 3).
Contexto
What changed: Households received a multi-burner LPG stove, free continuous fuel refills, and behavioral messaging for 18 months. Comparison: Control households continuing customary biomass stove use. Limits: High adherence was supported by free fuel delivery and visits, which may exceed real-world policy uptake.
