WHO: Burden of disease from Household Air Pollution for 2012

WHO: Burden of disease from Household Air Pollution for 2012
Released March 2014
Summary of results
Globally, 4.3 million deaths were attributable to household air pollution (HAP) in 2012, almost all in low and middle income (LMI) countries. The South East Asian and Western Pacific regions bear most of the burden with 1.69 and 1.62 million deaths, respectively. Almost 600’000 deaths occur in Africa, 200’000 in the Eastern Mediterranean region, 99’000 in Europe and 81’000 in the Americas. The remaining 19’000 deaths occur in high income countries.
The large increase in burden compared with the previous estimate of 2 million deaths from HAP from 20041 is mainly due to 1) additional health outcomes such as cerebrovascular diseases and ischaemic heart disease included in the analysis2; 2) additional evidence that has become available on the relationship between exposure and health outcomes and the use of integrated exposure-response functions3; and 3) an increase in non-communicable diseases.
Although women experience higher personal exposure levels than men2,4 and therefore higher relative risk to develop adverse health outcomes due to their greater involvement in daily cooking activities, the absolute burden is larger in men due to larger underlying disease rates in men.
