The Andra Pradesh State Road Transport Corporation Study

India stands third with respect to the road transport network amounting to 3,320,410 Kms. Buses take up over 90% of public transport in Indian cities, and serve as a cheap and convenient mode of transport for all classes of society. Services are mostly run by state government owned transport corporations.

Subjected to the nature of their work, bus drivers and conductors are constantly exposed to an ever increasing polluted environment, putting them at a high risk of airways diseases. Chest Research Foundation took up the initiative to study the prevalence of obstructive airways diseases in this specific population.

Being the first of its kind, a state road transport had to be targeted for easy accessibility. The Andhra Pradesh State Road Transport Corporation, acknowledged in 1999 by the Guinness World Records as possessing the largest fleet of buses owned by a State Corporation, was chosen for this study. The current fleet stands at 22,265 buses and 210 depots, covering a distance of 8.1 million kilometres of road every day. The number of passengers transported everyday by the APSRTC is equivalent to the number of passengers transported per day by the entire Indian Railways. The APSRTC has a total of 1,20,699 employees. These include bus drivers, conductors, garage workers, office based workers and miscellaneous workers like security, housekeeping, etc.

Chest Research Foundation conducted a study in 24 of the randomly selected bus depots from amongst the 210, which included a total of 7154 people including drivers, conductors, garage workers, office workers and others (security, housekeeping, etc.

We intended to study the respiratory health of these people with a major focus on obstructive airways diseases in the Andhra Pradesh State Road Transport Corporation employees. We administered a respiratory health questionnaire, performed peak flow metry and Spirometry, and measured blood pressure. Student volunteers administered the Questionnaire, performed Peak flow metry and measured the blood pressure while Spirometry was performed by the Cipla Care and Educator team.

Data was collected from the depots and sent to CRF for data management. Quality assurance of the spirograms was conducted and poor quality graphs were rejected to obtain a clean database of good quality spirograms only.

The analyzed data was presented at the ERS, 2011 in September at Amsterdam. Further analysis will be presented at ERS 2012.
