Adverse health effects associated with household air pollution: a systematic review, meta-analysis, and burden estimation study

Abstract

Background 3 billion people worldwide rely on polluting fuels and technologies for domestic cooking and heating. We estimate the global, regional, and national health burden associated with exposure to household air pollution.Methods For the systematic review and meta-analysis, we systematically searched four databases for studies published from database inception to April 2, 2020, that evaluated the risk of adverse cardiorespiratory, paediatric, and maternal outcomes from exposure to household air pollution, compared with no exposure. We used a random-effects model to calculate disease-specific relative risk (RR) meta-estimates. Household air pollution exposure was defined as use of polluting fuels (coal, wood, charcoal, agricultural wastes, animal dung, or kerosene) for household cooking or heating. Temporal trends in mortality and disease burden associated with household air pollution, as measured by disability-adjusted life-years (DALYs), were estimated from 2000 to 2017 using exposure prevalence data from 183 of 193 UN member states. 95% CIs were estimated by propagating uncertainty from the RR meta-estimates, prevalence of household air pollution exposure, and disease-specific mortality and burden estimates using a simulation-based approach. This study is registered with PROSPERO, CRD42019125060. Findings 476 studies (15•5 million participants) from 123 nations (99 [80%] of which were classified as low-income and middle-income) met the inclusion criteria. Household air pollution was positively associated with asthma (RR 1•23,

Adverse Birth Outcomes Due to Exposure to Household Air Pollution from Unclean Cooking Fuel among Women of Reproductive Age in Nigeria

“…Poverty has also been suggested to be a key factor in preventing access to clean fuel but also compounds the burden associated with HAP by worsening access to adequate health care [ 51 ]. This may be a contributing factor to the regional disparity seen between the mostly lower socio-economic demographic of the North compared to the mostly higher socio-economic demographic of the South.…”

Indoor Air Quality at Home—An Economic Analysis

“…Figures 3-5 present the incremental cost pre-and post-intervention with varying levels of effectiveness and intervention costs for people with asthma, living in extreme risk dwellings that are considered either non-decent, to have a usable floor area <90 m 2 or to have any damp problems respectively. The results of the analyses demonstrate that at a given level of effectiveness, the threshold for the upfront cost of the intervention to remain cost-saving is equivalent across the different home characteristics.…”

“…People in Europe spend up to 90% of their lives indoors and 66% of this time is spent at home [ 1 ]. Indoor air quality has an impact on multiple health outcomes, including respiratory and cardiovascular illness, allergic symptoms, cancers and premature mortality [ 2 , 3 ]. Common pollutants include particulate matter (PM 2.5 and PM 10 ); nitrogen dioxide (NO 2 ); and volatile organic compounds (VOCs) including benzene, formaldehyde and polycyclic aromatic hydrocarbons (PAHs).…”

“…High indoor particulate matter, NO 2 and VOC levels were typically associated with respiratory symptoms, particularly asthma symptoms in children [ 3 ]. A systematic review of studies from 123 countries showed that the relative risk (RR) for asthma associated with the use of polluting fuels and technologies was 1.23 (95% CI: 1.11–1.36), and the RR for chronic obstructive pulmonary disease (COPD) was 1.70 (95% CI: 1.47–1.97) [ 2 ]. Therefore, children and people with either respiratory, cardiovascular, or both conditions are considered most vulnerable to health problems caused by indoor air quality [ 1 ].…”

“…9 Studies have shown that emissions from kerosene combustion increase the risk of asthma, pulmonary tuberculosis, cardiovascular disease, cerebrovascular disease, cancer, stillbirth, etc. 10 Plant-based remedies have proven to be useful in the treatment and management of diseases and specifically the toxicity caused by hydrocarbons and other constituents of petroleum and petrochemical products. 11 It is estimated that up to 80% of the population in developing countries rely on traditional medicine for their primary healthcare need.…”
