The study in one paragraph

Vaayu Chest & Sleep Specialists screened 2,450 traffic police personnel in Bengaluru for respiratory symptoms, lung function and other chronic conditions. It is the largest occupational-health screening study of traffic police in India. The work looked at respiratory disease together with conditions such as hypertension and diabetes, because long-term exposure to traffic pollution affects the heart and other organs as well as the lungs.

Where it was presented and published

“Respiratory and Multimorbidity Analysis in 2,450 Traffic Police Personnel in Bangalore City”: presented at the European Respiratory Society (ERS) Congress 2025, Amsterdam, and published in Lung India, the journal of the Indian Chest Society.
“An Observational Study on Respiratory Morbidity and Lung Assessment in 2,450 Traffic Police Personnel in Bengaluru City”: presented at the National Respiratory Meeting (NAPCON), Pune, August 2025.

What was measured

Each participant had a general health assessment (blood pressure, heart rate, oxygen saturation, BMI, random blood sugar) and a respiratory assessment: symptom and exposure history, doctor consultation, spirometry, Forced Oscillation Technique (FOT), Fractional exhaled Nitric Oxide (FeNO) where available, and a chest radiograph.

Latest figure from the wider programme

Screening has continued since the study cohort. Across the 3,287 traffic police personnel screened by VORIC to date, reduced lung function was found in 28%, as presented at the roundtable “Protecting Those Who Protect Our City” in Bengaluru in October 2026.

What happens next

VORIC runs a five-year longitudinal research collaboration with the Indian Institute of Science (IISc) and the Public Health Foundation of India (PHFI) on the impact of pollution on traffic police personnel, and Karnataka's Home Department has launched statewide respiratory surveillance for traffic police.
