Abstract
Background and Objectives: Musculoskeletal disorders and low quality of life are the most common problems among paddy farmers in the world. Paddy farmers are exposed to inappropriate postures, long working hours and stressful environmental conditions. The aim of this study was to compare different farming methods of rice cultivation (traditional and semi-modern) on the prevalence of musculoskeletal disorders and life quality of paddy farmers.
Methods: This descriptive-analytical study was conducted in rice fields with 150 paddy farmers as a sample group (100 traditional paddy farmers and 50 semi-modern paddy farmers). Musculoskeletal disorders and quality of life were assessed using the Nordic questionnaire and the Lancashire Quality of Life Profile, respectively.
Results: The prevalence of musculoskeletal disorders in the neck, lower back and shoulders is higher in traditional paddy farmers compared to farmers who work in semi-modern rice cultivation system. Present results demonstrated that there was no significant difference between various rice cultivation methods and musculoskeletal disorders on life quality. Furthermore, different farming methods of paddy cultivation have no significant effect on paddy farmers' life quality.
Conclusion: The prevalence of lower back musculoskeletal disorders among paddy farmers portrays the consequence from long-term exposure to inappropriate posture from strenous activity.

Abstract
Objectives: Administrative employees are often at risk of developing musculoskeletal disorders due to prolonged computer use. Additionally, frequent interactions with clients expose them to a high mental workload and job stress. The present study aimed to assess the prevalence of musculoskeletal disorders, mental workload, general health, and job stress among administrative employees to improve their working conditions.
Methods: The present work followed a cross-sectional descriptive-analytical method and was conducted on the administrative employees of an engineering company in 2021. Finally, 119 individuals participated in the study using the census method. Demographic information questionnaires, as well as Rapid Office Strain Assessment (ROSA), Cornell, NASA Task Load Index (NASA-TLX), General Health Questionnaire (GHQ), and Health and Safety Executive (HSE)-UK job stress checklists were used to collect data. Data analysis was performed using the SPSS software, employing descriptive statistics, independent t-tests, and one-way analysis of variance (ANOVA).
Results: According to the posture assessment with the ROSA method, the average final ROSA score was 4.33±1.03. Examination of mental load with the NASA-TLX indicated that 78% had a high mental load. In addition, according to the GHQ questionnaire, the average final general health score was 24.4±11.73. Moreover, based on the HSE-UK occupational stress questionnaire, more than 80% (103 people) of employees were under severe stress, and 12% (15 people) were under critical stress. A significant relationship was observed between occupational stress, body mass index (BMI), and age (P<0.05).
Conclusion: The implementation of intervention and control measures to improve musculoskeletal disorders, workload, general health, and job stress seems to be essential.
