Among various health assessment tools for industrial workers, Pulmonary Function Test (PFT) is one of the most popular tools. PFT results are closely related to people’s lifestyle. People who perform regular exercises are found to have good results in PFT. Physical activity demands strong cardiopulmonary system that is again responsible for the body’s physiological condition. The objective of this study is to compare pulmonary functions among the female workers of jeans industry in Ballari with normal healthy subjects.50 females working in various jeans manufacturing units of Ballari and 50 housewives, each between ages 18-35 years were selected for the study. This study is a comparative study and was conducted over a period of 3 months i.e., December 2020 to February 2021, When Covid-19 crisis (first wave) had subsided completely. The study requires onetime assessment of lung functions of the 100 female participants (50 jeans factory workers and 50 housewives) using RMS Helios-401 PC based Spirometer which is owned by the principal investigator. In the research, the same effect has been observed among females working in a factory and the females not working in a factory. Here these females are potentially exposed to dirt and toxic chemicals, due to which the working of their respiratory function has reduced.
