Correlation of duration of exposure with PEFR in flour mill workers: A cross sectional study

Abstract

Study objective: To correlate duration of exposure with PEFR in flour mill workers.Materials and methods: 90 participants working in flour mill with duration of exposure ranging from 5 years to 50 years were enrolled in the study. Their predicted PEFR was calculated and actual PEFR was obtained using “Peak Flow Meter”. Correlation was done according to the years of exposure.Conclusion: There is a strong correlation between years of exposure and decline in PEFR in Flour mill workers.
