Background: Studies performed in different jobs have reported different prevalence rates of musculoskeletal disorders which, if detected, can be improved by proper movements and behavioral patterns. Considering the importance of health in military personnel, the present study aimed to assess the prevalence of musculoskeletal disorders and its association with Body Mass Index (BMI) in Military University students.
Methods: In this descriptive-analytical study, 400 military students were selected through multi-stage cluster sampling in 2013. Postural abnormalities were examined using scoliometer, goniometer, chessboard, and flexible ruler. Then, the data were entered into the SPSS statistical software (v. 16) and analyzed using correlation coefficient tests.
Results: The results showed that 41.25% of the subjects (n=165) had at least one spinal disorder. Besides, the most and least prevalent abnormalities were lordosis (26.25%) and pelvic tilt (7.75%), respectively. Moreover, a significant correlation was observed between BMI and spine curves (lordosis, kyphosis, and scoliosis) (P<0.05).
Conclusion: The study results showed that the prevalence rate of musculoskeletal disorders was far lower in military personnel compared to other jobs. It seems that regular exercise programs and strengthening the muscles of upper extremities, particularly the muscles that support the spine, are important in reducing these abnormalities.
