Indoor Air Pollution Caused by Cookstoves poses Health Risks

According to the World Health Organisation (WHO) there are 4 million premature deaths (predominantly caused by respiratory and cardiovascular diseases) each year attributed to household air pollution created by using wood, coal and other solid fuels for cooking and heating homes. A novel multi-country trial is being carried out by the National Institutes of Health (NIH), with partial support through a grant from the Bill & Melinda Gates Foundation to tackle the global health problem. The multi million-dollar study will determine if using widely available, clean, alternative cooking fuel significantly reduces deaths and illnesses. The 5-year study is part of a broader international effort to research chronic lung diseases which is coordinated by the Global Alliance for Chronic Diseases (GACD).

The NIH Director Francis S. Collins commented on the matter:

“Indoor air pollution caused by cookstoves is one of the top health risks in developing countries, causing deaths from low birth weight among babies, pneumonia in young children, and heart and lung problems in adults. By working with our global partners on alternative fuel solutions, we have an opportunity to reduce that risk significantly for millions of people.”

According to the WHO there are approximately 3 billion people worldwide who are reliant on using solid fuels for both cooking and heating. The indoor pollution generated can cause a range of diseases such as: pneumonia, heart disease, cancer and chronic lung disease.

The study which is led by Emory University in Atlanta, plans to recruit 800 pregnant women at a number of trial sites and will randomly assign half to receive liquefied petroleum gas (LPG) stoves and a supply of gas. The trial will run until the child is 2 years old, a number of medical measurements will be then taken i.e. did the mother suffer from hypertension during pregnancy, incidence of pneumonia and growth and development of the infants. Addition to this, several hundred older women will be assigned at each site and monitored to assess cardiopulmonary, metabolic and cancer outcomes. Biomarker analysis of blood and urine samples will also be carried out.

This cutting-edge study will hopefully provide an essential insight into the effects of air pollution produced by cookstoves reliant on LPG on health. The trial will also provide scientific evidence of potential alternatives to using solid fuels which may subsequently reduce the number of health issues related to indoor air pollution.
