Modeling the Major Ailments of Petroleum Workers with Associated Risk Factors using Logistic Regression Approach

Petroleum workers directly expose to both petroleum vapors and liquid petroleum products. Long-term exposures to the petroleum products have been shown to affect functioning of different systems of the body. The effects may result in accelerated decline in lung functions, increase in skin rashes, increase in visual problems and increase graying hair.
