Driving bus in an urban area is a demanding job and requires tremendous amount of physical and mental stability to perform the task with minimal hazards. Bus drivers are under continuous stress during the working hours and are prone for many diseases related to the changes induced by stress, especially cardiovascular disorders.
Study Objective: To evaluate cardio-respiratory fitness using three min step test and prediction of future risk of CAD using IPAQ, ACSM risk factor stratification scoring in public transport bus drivers of Mumbai and Navi Mumbai.
Methodology: 100 public transport bus drivers were included according to inclusion and exclusion criteria between the age group of 25-55 years. Bus drivers were interviewed for IPAQ questionnaire, ACSM risk factor stratification scoring and perceived stress scale. Cardio-respiratory fitness was evaluated and the recovery heart rate was recorded. Spearman’s correlation test was carried out using SPSS (version16).
Result: Our study revealed strong positive correlation between three (3) minute step test recovery heart rate and ACSM risk factor stratification scoring (r=0.803, p=0.00), derived Vo2max and IPAQ (r=0.588,p=0.00)and strong negative relation between 3 min step test recovery heart rate and IPAQ (r=-0.589,p=0.00), derived Vo2max and ACSM risk factor stratification scoring (r=-0.788,p=0.00), ACSM risk factor stratification scoring and IPAQ (r=-0.719,p=0.00).
Conclusion: Our study demonstrated a moderately high prevalence (93%) of CAD risk factors amongst bus drivers of Mumbai and Navi Mumbai. Sedentary life style was found to be the commonest risk factor amongst the entire study population followed by stress, smoking and dyslipidemia.
