Epidemiological aspects of indoor air pollution

Adverse health outcomes from exposure to air pollution have been documented for decades. Not only outdoor air pollution but also indoor air pollution also has harmful effects. Indoor air pollution significantly affects occupants’ health as people spend most of their time indoors performing activities of daily living, working, and sleeping. Numerous epidemiological studies have demonstrated that exposure to indoor air pollution results in adverse health outcomes. Various kinds of indoor air pollution have different effects on occupants. Environmental conditions and human characteristics are associated with disease distribution, and individuals experience outcomes differently. Some factors may increase the risk of adverse health outcomes, while others can promote health and well-being. This chapter aimed at summarizing the epidemiological aspects of exposure to indoor air pollution and summarizing the distribution of diseases caused by indoor air pollution among occupants in different indoor environments. Additionally, a summary of the epidemiological study design commonly used in investigating the distribution and factors associated with indoor air pollution-related disease is provided. © 2024 Elsevier Inc.
