This study aimed to comprehensively and methodically evaluate the correlation between cognitive impairment and indoor air pollution from solid fuel used for cooking/heating. PubMed, Web of Science, EMBASE, and Cochrane Library databases were searched up to December January 2023. 13 studies from three countries with a total of 277,001 participants were enrolled. A negative correlation was discovered between solid fuel usage for cooking and total cognitive score (β=-0.73, 95 % CI: -0.90 to -0.55) and episodic memory score (β=-0.23, 95 % CI: -0.30 to -0.17). Household solid fuel usage for cooking was considerably associated with a raised risk of cognitive impairment (HR=1.31, 95 % CI: 1.09-1.57) and cognitive decline (HR=1.24, 95 % CI: 1.18-1.30). Compared to continuous solid fuel use for cooking, sustained use of clean fuel and switching from solid fuel to clean fuel were associated with a lower risk of cognitive decline (OR=0.55, 95 % CI: 0.42-0.73; OR=0.81, 95 % CI: 0.71-0.93). A negative association was found between solid fuel usage for heating and total cognitive score (β=-0.43, 95 % CI: -0.59 to -0.26) and episodic memory score (β=-0.22, 95 % CI: -0.34 to -0.10). Our research provided evidence that exposure to indoor air pollution from solid fuel is a potential cause of cognitive impairment and cognitive decline. Making the switch from solid fuels to cleaner fuels could be an important step in preventing cognitive impairment in the elderly.
本研究旨在全面且系统地评估烹饪/取暖用固体燃料造成的室内空气污染与认知障碍之间的相关性。截至2023年1月，对PubMed、Web of Science、EMBASE和Cochrane图书馆数据库进行了检索。纳入了来自三个国家的13项研究，共有277,001名参与者。发现烹饪用固体燃料的使用与总认知得分（β=-0.73，95%CI：-0.90至-0.55）和情景记忆得分（β=-0.23，95%CI：-0.30至-0.17）之间呈负相关。家庭烹饪用固体燃料的使用与认知障碍风险升高（HR=1.31，95%CI：1.09-1.57）和认知衰退（HR=1.24，95%CI：1.18-1.30）显著相关。与持续使用固体燃料烹饪相比，持续使用清洁燃料以及从固体燃料转换为清洁燃料与较低的认知衰退风险相关（OR=0.55，95%CI：0.42-0.73；OR=0.81，95%CI：0.71-0.93）。发现取暖用固体燃料的使用与总认知得分（β=-0.43，95%CI：-0.59至-0.26）和情景记忆得分（β=-0.22，95%CI：-0.34至-0.10）之间呈负相关。我们的研究提供了证据，表明接触固体燃料造成的室内空气污染是认知障碍和认知衰退的一个潜在原因。从固体燃料转换为更清洁的燃料可能是预防老年人认知障碍的重要一步。
