Abstract
Background: Musculoskeletal disorders (MSD) represent one of the most frequently occurring and costly occupational issue in nursing. The nursing profession is one of the most stressful occupations today, because of the quantity and diversity of risk factors associated with the work environment. The aim of this study was to examine the relationship between burnout syndrome and musculoskeletal disorders. Material and Methods: In this cross-sectional study a questionnaire survey was carried out among 415 nursing personnel in five educational hospitals in Hamedan, Iran. Data were collected through two unnamed questionnaires including Maslach Burnout Inventory, Visual Analogue Scale (VAS). Results: Statistical analysis showed that the most commonly painful regions among the nurses were lower back (5.53%), left foot (5.08%), and head and neck (4.43%), right foot (4.90%), right knee (3.84%) and left knee (3.74%). The lowest pain, were found to be in right and left elbows (1.99%) and (1.91%), respectively. Also emotional exhaustion, depersonalization and personal accomplishment has significant correlation with musculoskeletal disorders (P = 0.000, r = 0.122). Conclusions: The results showed high prevalence of MDS among Iranian nurses that could be due to emotional exhaustion and depression.

Abstract
To determine the occurrence of Work related Musculoskeletal Disorder (WMSD), its prevalence and risk factors among school teachers in India. 100 questionnaires was passed out and sent to teachers of different schools ranging from primary school to higher secondary schools across Kolkata and Aizawl. 72 percent of the teachers responded. A standardized Dutch Musculoskeletal Questionnaire (DMQ) was used. Neck pain was the most prevalent musculoskeletal complaint, reported by 53.52% of the respondents while chronic neck pain was not reported by the teachers. Shoulder and back pain were less prevalent than neck pain but the prevalence of chronic pain in these body sites were higher. Furthermore wrist/hand and knee pain were less prevalent than the other complaints. Working with hands above the shoulder was the highest reported risk factor (62.27%). School teachers are susceptible to WMSD with a significant prevalence for neck, shoulder, back, wrist/hand and knee pain. Prolonged working nature like bending the neck forward/backward or holding the neck in a Forward/backward posture, same movements with arms, hands or fingers many times, hands above the shoulder level, reaching with arms or hands and standing are important factors which affect the occurrence of musculoskeletal disorders.

Abstract
Background: In today's world, Musculoskeletal Disorders (MSDs) with high prevalence in work settings are one of the most important occupational health issues. In addition, MSDs cause personal distress, decreased working capacity, and waste of time, work absenteeism, increased health care costs and economic losses. This study aimed to compare the prevalence rate of MSDs and their associated factors among farmers and workers in Agh Ghala.
Methods and Materials: This study was a cross-sectional study. The study population consisted of 300 patients (150 farmers and 150 workers) who were selected from Agh Ghala city in Golestan province. The data collection instrument was Nordic questionnaires. The data were analyzed using descriptive statistics and chi-square test in SPSS software version.
Results: In this study, about 72% of the farmers (N = 108) and 83.33% of the workers (N = 125) were suffering from MSDs during the preceding year. The most common disorders were Lower Back Pain (LBP) 36.7% (N = 55) and 55.3% (N = 83) in farmers and workers respectively, followed by knee pain 25.3% (N = 38) and 36.7% (N = 57) in farmers and workers respectively. The chi-square test showed a significant relationship between the MSDs and age, level of education, and training in ergonomic principles (P <.05). The finding suggested that there was no significant relationship between MSDs and Body Mass Index (BMI) in both groups (P < 0.05).
Conclusion: Regarding the high prevalence rate of MSDs, it is necessary to organize training courses about professional ergonomic interventions in order to raise farmers' and workers' awareness and skills. These programs can be used to improve the health behsubsequentubsequently healthworkers, duefarmers and workers due to preventing from the occurrence of musculoskeletal disorders.

Abstract
Aims: In developing countries such as our country, most of the activities such as carpentry is performed manually and make workers exposure to inappropriate postures, which will increase the prevalence of Musculoskeletal Disorders (MSDs). One way to reduce these disorders is educational ergonomics interventions. The present study aimed at determining the effect of education on reducing ergonomic risk in traditional carpet weavers working in workshops in Golestan province, Iran.
Materials & Methods: This quasi-experimental study was conducted on 100 employees in 54 traditional workshops in Golestan province of Iran in 2016. The studied population consisted of horsewomen carpet weavers who had at least one-year work experience and were selected based on simple random sampling method. The QEC method was used to assess the risk of musculoskeletal disorders and Nordic standard questionnaire was used to determine the frequency of symptoms of these disorders. The data were analyzed by SPSS 19, using paired sample t-test and Wilcoxon.
Findings: In the pre-interventional stage, the greatest risk was related to the neck (71.0%) at high-risk level. This intervention was significantly reduced from interventional, and only 5.0% of subjects were at this level (p<0.001). The waist circumference was 97.0% of the subjects before the training at the level of intermediate exposure. After intervention, this amount decreased and most of the subjects (64%) were exposed to low levels of exposure.
Conclusion: Education can reduce ergonomic risk in traditional carpet weavers working in workshops.

Aims: Despite the high incidence of wrong ways to wear a backpack in students, the relevant musculoskeletal complications, and the effective role of health education in modification of this behavior, there is no standard questionnaire in this regard in Iran. The aim of this study was to assess the psychometric evaluation of a questionnaire on backpack carrying among female high school students.
Instruments & Methods: The questionnaire on how female high school students carry their backpack in Babolsar, Mazandaran province included 31 items for knowledge (12 items), attitude (10 items), and behavior (9 items) derived from evidenced literature. This questionnaire was evaluated in terms of content and face validity and reliability through internal consistency and stability in 2018. The qualitative and quantitative content validity was evaluated by the panel of experts through Content Validity Index (CVI) and Content Validity Ratio (CVR). Qualitative and quantitative face validity was assessed by the students’ views and measuring impact score, respectively. Internal consistency and stability were measured by Cronbach’s alpha and Intraclass Correlation Coefficient, respectively. Data were analyzed by SPSS 21.
Findings: The results of CVI (0.9-1), CVR (0.8-1), and impact score (2.5-3) were acceptable for the whole scale. Qualitative content and face validity was favorable. Cronbach’s alpha coefficients were appropriate for the whole scale (0.77) and of knowledge (0.68), attitude (0.8), and behavior (0.77). The interclass correlation coefficient for the whole questionnaire (0.68) and the domains of knowledge (0.61), attitude (0.71), and behavior (0.72) indicated that the questionnaire was acceptable.
Conclusion: The study showed the validity and reliability of the health questionnaire on carrying backpack among female high school students. However, more researches should be done to verify this questionnaire for measuring knowledge, attitude, and behavior regarding backpack carrying.

Abstract
Aim: Musculoskeletal Disorders (MSDs) are the main cause of occupational disorders and disabilities in the developing countries. The goal of this study was to assess the prevalence of the MSDs in steel Industry workers using Nordic Musculoskeletal Questionnaire (NMQ), and its relationship with the Rapid Upper Limb Assessment (RULA) results.
Instruments & Methods: The present research was a descriptive-analytic study conducted on the Iranian steel industry in 2018. A total of 17 workstations were randomly selected and NMQ was used to explore the prevalence of the symptoms of Work-related Musculoskeletal Disorders (WMSDs). Afterwards, the workers’ postures were assessed via RULA. Finally, the results were analyzed in SPSS 22 through the chi-square test, independent t-test, and analysis of variance (ANOVA) method.
Findings: This study showed the significant relationship between the results from the Nordic assessment of the back, knee, and neck within the past 12 months and profession type (p<0.05). However, the final assessment scores, corrective measures priority, and Nordic assessments of the back, neck, and knee of the workers showed no significant relationship with work experience (p>0.05).
Conclusion: The findings of this study revealed that in order to considerably reduce the musculoskeletal disorders in the steel industry workers, immediate measures must be taken to correct the back and neck postures especially in the scrap shear operators, welders, ingot shear operators, electrical technician, tower operator, and guillotine operators.
