Number of deaths attributable to household air pollution resulting from solid fuels for cooking. Evidence from epidemiological studies have shown that exposure to smoke from incomplete combustion of solid fuels is linked with a range of conditions including acute and chronic respiratory diseases. Of these, evidence for three have been assessed on sufficiently strong basis for inclusion in the burden of disease estimates: Acute lower respiratory infections in young children (under 5 years) Chronic obstructive pulmonary disease in adults (above 25 years) Lung cancer in adults (above 25 years) Additional evidence based on exposure-response functions identifies household air pollution as risk factor for cardiovascular diseases such as: Ischaemic heart disease in adults (above 25 years) Cerebrovascular diseases (stroke) in adults (above 25 years) Estimated health impacts are limited to those age ranges.
