Associations between Predictors of Indoor Air Quality in Kosovo and Health Symptoms in a Large Representative Survey

Abstract

Because most human activities take place inside, indoor air quality is essential to human health. Numerous factors contribute to Kosovo’s air pollution, including traffic, industrial emissions, aging thermal power plants, home heating, and other hazardous pollutants. The National Institute of Public Health and the WHO conducted a representative household survey to identify the most exposed and susceptible households, targeting two thousand households. Data from this survey were analyzed regarding the relationship between residential air quality predictors and health symptoms in Kosovo inhabitants. Effects from cooking fuel used on headaches, dizziness, and fatigue were somewhat stronger in females and type of heating seemed a little bit more effective in winter. The latter was also true for respiratory problems and heart disease, lending some credence to the causality of the findings. Thus, cooking devices and energy sources for both heating and cooking seem to have an effect on the health of Kosovars. Although the effect estimates were, in general, moderate with adjusted odds ratios in the magnitude of 2 to 3, they only explained a small part of the variation, with pseudo-R² often only reaching less than 10% and rarely more than 20%. In order to improve indoor air quality, regular monitoring and supervision systems should be established across the nation.
