ABSTRACT
Objectives: To see the pulmonary functions in students of 1st year and 4th year MBBS, SIMS and to compare them with each other considering the Environmental and stress related factors affecting Pulmonary functions on both groups
Methods: 30 students from each 1st and 4th year were taken from Services Institute of Medical Sciences Lahore. Consent in written was taken, participants were questioned and spirometery tests were performed. Data was analyzed using SPSS version 20
Result: Age and BMI of both groups were comparable. The mean values of FEV1 was better in 4th year students [3.2830 +/- 0.7677 V/S 3.2357 +/- 0.8223] and it was not statistically significant [p =0.819]. Values of FVC and FEV1 were better among 4th year students who exercise daily with values of 4.2323 +/- 0.5078 and 4.2343 +/- 0.3070 respectively than those of 1st year students have values of FVC and FEV1 as 4.0057 +/- 0.5022 and 3.7629 + 0.5268. The difference is statistically significant [p= 0.043 and 0.028 respectively]. The mean values of Forced Volume Capacity and Forced Expiratory Volume 1 of students residing in hostels were better in 4th year students [4.0171 +/- 0.8698 and 3.4129 +/- 0.9089 respectively] but it was not statically significant
Conclusion: Pulmonary functions were slightly better in 4th year students. It was due to their resistance to cope up with the environment, stress related to studies and better life styles regarding exercise and less numbers of smokers
