Assessment of Physiological Health Status in Relations to Different Anthropometric and Cardio-Respiratory Measures of Head-Supported Load Carrying Male Porters of Sikkim, India

Abstract

Background: Carrying heavy loads in the hilly region, porters face extreme ranges in terrain condition, sloped path that is very steep and lack of oxygen due to altitude. The porters in Sikkim, India, routinely carry head-supported loads, which often exceed their body weight, over long distances up and down the steep mountain footpaths which prompted us to assess occupational health status of these head supported load carrying porters. Objective: We aimed our study to evaluate physical and physiological status of male porters of Gangtok, Sikkim. Methods: Seventeen male porters and twenty one healthy as well as age matched (Age: 37 – 52 years) control subjects were selected for the study. Different physical, anthropometric and physiological parameters were studied. Students “t” test was performed to find out the significant difference (P<0.05), if any, between the selected variables. Results: Results of this study on male porters suggest that they are physically healthy but having spinal shrinkage along with lower hand grip strength and PEFR. Conclusion: This study supports the hypothesis that the male porters are associated with decreased lung function and increased spinal shrinkage. To develop an effective intervention strategy, the treatment seeking behavior of individuals would also need to be improved through awareness program.
