Background and Objective : Musculoskeletal disorders (MSDs) are common problems in hospitals. Very few studies focused on back office staff as well as healthcare workers who were at high risk for MSDs. Thus, the present study aimed to determine the prevalence and related factors of MSDs among hospital back office staff.
Methodology : A cross-sectional study was conducted on 220 back office staff working at Mahasarakham Hospital. The data was collected by self-administered questionnaires which comprised personal data and working conditions. Standard Nordic questionnaire was also employed to evaluate MSDs in the previous week and year. To investigate the related factors, forward stepwise logistic regression was utilized.
Results : The study showed that the prevalence rate of MSDs in the previous week was 79.1% and 77.7% in the previous year at any body site. The highest prevalence was in shoulders (54.5% in the previous week and 59.1% in the previous year) followed by neck (48.6% in the previous week and 48.6% in the previous year) and lower back (40.9% in the previous week and 41.8% in the previous year). The significant factors found to be associated with MSDs in the previous week were female (Oddadj=2.6, 95% CI=1.15-6.09), exercise (Oddadj=2.8, 95% CI=1.29-6.30), accident (Oddadj=3.2, 95% CI=1.29-8.08), improper chair cushion (Oddadj =3.4, 95% CI=1.29-9.16), moderate work-related fatigue (Oddadj=2.7, 95% CI=1.03-7.45), and severe work-related fatigue (Oddadj=5.6, 95% CI=1.48-21.53). However, there was no significant factor associated with MSDs in the previous year in the multivariable model.
Conclusion : The prevalence rate of MSDs among back office staff was high and the improvement in working conditions, especially work-related fatigue, are necessary to prevent MSDs.
