Household air pollution has been estimated to be responsible for 3.2 million preventable deaths every year globally. With biomass exposure and environmental pollution linked to exacerbations of airways disease, this health impact disproportionately affects low and middle income countries. Puzzolo et al ( Lancet Resp Med 2024;12(4):281–293) undertook a systematic review and included 116 studies in the subsequent meta-analyses, to compare use of gaseous fuels in the domestic environment with more polluting fuels (wood/charcoal/kerosene) and cleaner fuels (electricity/solar) with no point of use pollution. Use of gas significantly decreased the risk of COPD (OR 0·37, 95%CI 0·23–0·60; p<0·0001), pneumonia (OR 0·54, 0·38–0·77; p=0·0008), deficits in lung function (OR 0·27, 0·17–0·44; p<0·0001), severe respiratory illness or death (OR 0·27, 0·11–0·63; p=0·0024) compared with more polluting fuels. Preterm births (OR 0·66, 0·45–0·97; p=0·033), and low birth weights were similarly reduced (OR 0·70, 0·53–0·93; p=0·015). Risk of asthma did not reach statistical significance. Gas compared with electricity did increase risk of COPD (OR 1·15, 1·06–1·25; p=0·0011) and pneumonia (OR 1·26, 1·03–1·53; p=0·025) but this was not significant in all studies. While having its own health and environmental impacts, switching to gas from more polluting fuels may reduce the burden of health risk in countries without …

据估计，全球每年有 320 万人因家庭空气污染而死亡。由于生物质暴露和环境污染与呼吸道疾病的恶化有关，这种健康影响对低收入和中等收入国家影响尤为严重。 Puzzolo 等人 (Lancet Resp Med 2024;12(4):281–293) 进行了系统回顾，并在随后的荟萃分析中纳入了 116 项研究，以比较家庭环境中气体燃料的使用与污染程度较高的燃料（木材/木炭/煤油）和清洁燃料（电力/太阳能），无使用点污染。使用气体可显着降低慢性阻塞性肺病 (OR 0·37, 95%CI 0·23–0·60; p<0·0001)、肺炎 (OR 0·54, 0·38–0·77; p= 0·0008）、肺功能缺陷（OR 0·27、0·17–0·44；p<0·0001）、严重呼吸道疾病或死亡（OR 0·27、0·11–0·63；p =0·0024) 与污染更严重的燃料相比。早产（OR 0·66、0·45–0·97；p=0·033）和低出生体重也同样减少（OR 0·70、0·53–0·93；p=0·015） 。哮喘风险未达到统计学意义。与电力相比，燃气确实增加了慢性阻塞性肺病（OR 1·15、1·06–1·25；p=0·0011）和肺炎（OR 1·26、1·03–1·53；p=0·025）的风险）但这在所有研究中并不显着。虽然对健康和环境有影响，但从污染更严重的燃料转向天然气可能会减轻没有……的国家的健康风险负担。
