Purpose of review Indoor air pollution (IAP) resulting from the use of solid fuel for cooking and heating is a significant public health concern in developing countries. Recent studies have attempted to better characterize the epidemiology of IAP in respiratory diseases and develop technologies for reducing this IAP exposure.

Recent findings Evidence showed that IAP resulting from solid fuel smoke is a causative or contributory factor to acute respiratory infection, chronic obstructive lung disease, asthma, lung cancer and tuberculosis. Evidence also showed that health education, improvements in household ventilation and area distribution, improvements in stoves and changes of the fuels for cooking and heating can reduce IAP.

Summary Evidence of impacts of IAP on respiratory system disease is strong. Although some technologies can improve indoor air quality in households, improving it in households is still an urgent and high-priority task. Longitudinal studies using different methods of exposure assessment that include both chemical measurements and activity data, with longer follow-up and larger samples, are needed. Any program for the prevention of IAP must be based on what is acceptable to the community, and the effects of the intervention must be evaluated.
