| dc.description.abstract | Background: Chronic respiratory disease is a global public health challenge, specifically among occupational groups exposed to environmental pollution. Traffic police, who are frequently exposed to high levels of ambient air pollution, face the risk of developing chronic respiratory diseases. Understanding the prevalence of respiratory symptoms, assessing the lung function of traffic police, and identifying predictor factors for respiratory symptoms among traffic police personnel is crucial for developing effective public health interventions. Objective: To assess the prevalence of chronic respiratory symptoms, lung function, and predictor factors among field and in-office traffic police personnel in Addis Ababa, Ethiopia. Methods: A comparative cross-sectional study has been employed. Targeting field and in-office traffic police personnel respectively, as exposed to Vehicular related air pollution and control group. A simple random sampling procedure was applied to enroll 374 traffic police personnel. Data were collected using the ATS/ERS questionnaire and spirometry following the American Thoracic Society guidelines to assess respiratory symptoms and lung function parameters, respectively. Chi-square test, ANOVA, Multivariable logistic, and linear regression were applied to compare prevalence, mean, and measure association. Result: A total of 374 traffic police personnel; 249 field traffic police and 125 in-office traffic police personnel were involved in the study. Respectively, field traffic police personnel were found to have a significantly higher prevalence of chronic respiratory symptoms than in-office traffic police personnel with 32.93% (27.36 - 39.03) and 18.4% (12.53 - 26.2) (p<0.003). Sex, work experience, and job status were significantly associated with developing chronic respiratory symptoms. While sex, age, being a field traffic police, years of employment, and previous occupational exposure to air pollutants demonstrate a negative relationship with lung function parameters (FEV1 and FVC) occupational safety and training on health topics showed a positive association with lung function parameters. Conclusion: field traffic police personnel have higher odds of developing chronic respiratory symptoms, with lower lung function compared to in-office traffic police personnel. Stricter air quality regulation, Occupational Safety, and Health-focused modifications in the traffic police work environment are recommended. Longitudinal studies should be conducted to investigate further the impact of air pollution on respiratory health among traffic police personnel. | |
