ClinConnect Summary

This clinical trial is looking into how using liquefied petroleum gas (LPG) for cooking and improving kitchen ventilation can help reduce harmful air pollution in homes and improve heart and lung health. The study will test four different groups: one group will continue using solid fuels without any ventilation, another will switch to LPG without ventilation, a third will keep using solid fuels but with better ventilation, and the fourth group will use both LPG and improved ventilation. The goal is to see if either method alone is effective, or if combining the two gives even better results. They will also look into how affordable and sustainable these changes are for households.

To participate, you must primarily use solid fuels like coal or wood for cooking and live in a home where ventilation can be installed. You should be between 18 and 74 years old and cook frequently. You will be randomly assigned to one of the four groups and provided with the necessary materials for your group. It's important to note that people with serious health issues, pregnant women, and smokers are not eligible to join. This study is not yet recruiting participants, but it aims to better understand how to improve indoor air quality and health in households.
