A cross-sectional study of lung functions in traffic police personnel at work in Kathmandu Valley, Nepal
BACKGROUND: The present study was aimed to assess pulmonary functions in the traffic police personnel (TPP) posted on traffic duty in Kathmandu valley, Nepal.
METHODS: The study group consisted of 17 females and 89 males, constituting 16% and 84% of the total police personnel studied, respectively. In the control group of 25 individuals, 16% (n=4) were female and 84% (n=21) were male. Portable desktop spirometer was used for the pulmonary function test (PFT) measurements.
RESULTS: It is seen that in females as compared to males, PFT parameters show a significant decrease. One-way ANOVA conducted to compare the effect of duration of air pollution exposure showed that there is a significant variation in PFT parameters among the groups. The exposure duration has significant effect on the PFT parameters.
CONCLUSION: Greater the officers are engaged in traffic duty for years, greater is the decrement in their lung functions test.
