Reducing indoor air pollution through behavioral nudges
Indoor air pollution exposure in households and associated health risks related to household energy use and cooking practices.
The study consists of two arms: a treatment group and a control group. Participants in the treatment group received a real-time indoor air quality intervention. This included the installation of a PM2.5 sensor with continuous display of air quality levels. The device provided immediate visual feedback and triggered a red alarm when air pollution exceeded a predefined threshold. In addition, participants were provided with an information leaflet explaining the health risks of air pollution and practical actions to reduce indoor air pollution exposure. Participants in the control group did not receive access to real-time air quality information or the informational leaflet during the study period. The total study duration was two months. This included a two-week baseline (pre-intervention) period during which no participants received the intervention, followed by six weeks of active treatment for the treatment group. Outcome measures were collected throughout both the baseline and treatment periods for all study arms. Participants were randomly assigned to the two groups using a pure computer-based randomisation process. Randomisation was conducted using an online tool without manual interference, ensuring allocation concealment and reproducibility.
