ABSTRACT
Background: The adverse effects of poor air quality on respiratory health have been well-documented. However, there remains a need for longitudinal studies to comprehensively understand the impact of air quality on respiratory health in urban environments.
Aim: This study aimed to conduct a longitudinal investigation spanning from May 2023 to April 2024 to analyze the relationship between air quality and respiratory health in an urban setting.
Methods: Ninety individuals residing in urban areas were selected as the study population. Various parameters of air quality, including particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3), were monitored continuously throughout the study duration. Additionally, participants underwent regular respiratory health assessments, including spirometry tests and symptom surveys. Statistical analysis, including correlation and regression analysis, was employed to assess the relationship between air quality parameters and respiratory health outcomes.
Results: Over the one-year duration of the study, significant correlations were observed between air quality parameters and respiratory health indicators. Increased levels of PM, NO2, and SO2 were associated with higher rates of respiratory symptoms and decreased lung function among participants. Furthermore, the effects were more pronounced during periods of poor air quality.
Conclusion: The findings of this longitudinal investigation highlight the detrimental impact of air pollution on respiratory health in urban environments. These results underscore the urgent need for effective air quality management strategies to mitigate the adverse health effects associated with poor air quality.
