Ramsha Ali Baloch, Afshan Khalid, Rashid Shar Baloch, Farkaleet Baloch

This cross-sectional study examined associations and effect between low intrinsic motivation, engagement efficacy and the prevalence of musculoskeletal disorders among blue-collar employees of sugar factories. Total participants of this study were 684 blue-collar employees of sugar factories and they completed medical record report and questionnaire yielding information on demographic variables, BMI, and physical job factors. The relationship and effects of physical and social factors with musculoskeletal disorders was analyzed by Pearson product moment correlation, odd ratios, chi square tests logistic regression models. In this study, we have discussed and analyzed the impact of intrinsic motivation of blue-collar employees as repercussions of chronic back strains and sprains injuries (MSD) working in sugar factories at Sindh province of Pakistan. This article entails statistical significance of the musculoskeletal disorders on employees’ productivity and engagement performance. This study was statistically evaluated by using data retrieved by the employees of seven different sugar factories. The subject populations have been prone to hopelessness, sleeplessness, loss of supportiveness, engagement efficacy and intrinsic motivation due to musculoskeletal disorders or back sprain and strain. We identified relationship between lower intrinsic motivation and engagement efficacy with loss of support of co-worker, supervisor, sleeplessness, hopelessness and back strain and sprain. This study yielded significant results and produced valid proportions among latent and observed variables. This study also opens the new research arena to combine social, behavioral and medical research relationship and to examine its possibilities and effectiveness.
