Driving has various harmful factors due to its nature, which affect drivers’ health directly and indirectly. Therefore, it is necessary to know the situation and prevalence of these factors in drivers to implement preventive measures.

This cross-sectional study is a part of a cohort study conducted (2016 to 2018) among the professional drivers of Shahroud, Iran. Data related to background information, blood pressure, height, weight, waist circumference, body mass index, blood factors, hearing loss (dB), respiratory performance indicators, sleep disorders, and accidents were collected from the participants with standard tools and methods.

This study examined 1461 male professional drivers with an average age of 37.30±6.96 years. A total of 426 participants had metabolic syndrome. 797 and 942 people had different degrees of hearing loss, respectively, in the right and left ear. About 129 people had obstructive sleep apnea, and 1330 people had insomnia. Investigations showed that 351 drivers had at least one accident.

This study showed the prevalence of health risk factors in professional drivers at the examined time point. Considering the vital role of drivers in transportation and the country’s economy, it seems necessary to pay more attention to the health of this occupational group. Regular health screening, healthy lifestyle training, improvement of working conditions, and stress management are some interventions that can effectively improve drivers’ health.

Today, various platforms, including virtual networks and websites, connect people with a lot of data via Internet. The attractiveness of these platforms sometimes makes people use them addictively. Uncontrolled use of the Internet may also cause problems such as reducing academic performance and creating musculoskeletal problems.

This cross-sectional study was conducted on 400 students at one of the universities of medical sciences. Four demographic questionnaires, Young's Internet addiction, Pham and Taylor's academic achievement and Nordic questionnaire were used to collect information. Data analysis was done using descriptive tests and Pearson's correlation, by SPSS V.16 software at a significance level of 0.05.

The highest prevalence of musculoskeletal disorders was related to the upper back (40.8%), lower back (36%) and neck (33.8%) regions. Among different parts of the body, reports of pain in the neck, shoulder, and wrist had a significant relationship with Internet addiction (P-Value: 0.038, 0.007, and 0.029, respectively). No significant relationship was found between different levels of Internet addiction and academic achievement.

The prevalence of musculoskeletal disorders is one of the complications of incorrect and unprincipled use of Internet-related equipment; Therefore, these problems can be reduced by providing appropriate educational platforms and creating a correct culture of using emerging technologies.

Work-related musculoskeletal disorders (WMSDs) are a prevalent occupational health concern, influenced by both physical and psychosocial factors. Valid questionnaires offer a cost-effective and efficient means of evaluating WMSDs. This study aimed to validate the Persian version of the MDRF questionnaire, assess its applicability in Iran, and investigate the prevalence of WMSDs among employees in an automotive industry.

This descriptive cross-sectional study was conducted among 100 employees (50 production line workers and 50 office workers) in Kerman province. The linguistic validity of the questionnaire and its translation were ensured using the Backward-Forward method. Content validity was assessed through CVI and CVR indexes. To evaluate the questionnaire’s reliability and agreement, Cronbach’s alpha and ICC were employed. User responses from the first and second series of the questionnaires were validated using Kappa and Spearman’s tests.

Results indicated high reliability which was achieved by Cronbach’s alpha and ICC values of 0.960 and 0.925, respectively. The questionnaire’s validity was acceptable based on CVR and CVI tests. The prevalence of WMSDs was the highest in the lower back for both production line and office workers over the past year. The job satisfaction factor exhibited the highest risk level among the questionnaire’s four subgroups. Approximately 85% of participants were classified as having a high or very high-risk level, reflecting concerning conditions among the employees. The prevalence of WMSDs in different body parts significantly correlated with all physical and psychosocial stress factors.

This research highlights the influence of diverse physical and psychosocial risk factors on the occurrence of WMSDs among both occupational workers and office employees. Also, the MDRF questionnaire, whose high applicability in assessing the WMSDs risk factors was proven in this study, is an effective tool for prioritizing, planning, and executing educational and preventive measures within the workforce community to mitigate and prevent WMSDs.

Studies have demonstrated that teaching carries a substantial burden of health risks. Prevalent health issues among teachers include asthma, respiratory diseases, musculoskeletal problems, and mental disorders. These problems can be attributed to the specific attributes of their work environment. Consequently, this study aims to investigate the correlation between air quality within educational establishments and the overall health of teachers.

This systematic review aims to examine the impact of temperature, humidity, and ventilation rates within educational environments on teachers’ health status and thermal comfort. Relevant studies were searched for using the PubMed and Web of Science databases, employing keywords such as teacher, temperature, humidity, ventilation, school, classroom, health symptoms, and thermal comfort (2000-2022). The inclusion criterion was that articles examined teachers’ health and comfort with temperature, relative humidity, and ventilation of the educational place.

Out of the 103 articles found in the initial search, 13 articles were finally reviewed. Six studies investigated the voice abnormalities of teachers due to various factors (including temperature, relative humidity, and the ventilation rate of the educational place) and found that these abnormalities were affected by these factors. Two studies explored the relationship between the prevalence and exacerbation of respiratory symptoms and quality parameters of the indoor environment of educational places. Additionally, five studies investigated the relationship of air quality parameters of educational places with common non-specific symptoms among teachers.

Teachers frequently experience symptoms such as voice disorders, respiratory difficulties, allergies, and other nonspecific ailments, which may be associated with the quality parameters of the indoor environment in educational settings. These parameters include temperature, humidity, and ventilation rate. Consequently, controlling and regulating these parameters within the recommended values can help prevent the onset or exacerbation of these symptoms.

The rise of computer use in office workplace has increased the prevalence of musculoskeletal disorders (MSDs) among computer users. The MSDs cause to reduce productivity, increasing the intention to leave and costs. The aim of this study was to determine the prevalence of musculoskeletal disorders and evaluate the effective risk factors using ROSA and RULA methods. This cross sectional study was conduct on Shahroud University of Medical Sciences' office workers (n = 153) who work more than 2 hours per day with computer. The employers according to inclusion and exclusion criteria were enrolled in this study. The data collection were used by Nordic standardized questionnaire, RULA and ROSA methods and analyzed by independent t-test, Pearson correlation coefficient, Chi-square and multivariate logistic regression. In both of RULA and ROSA, the highest risk level was in level 2, 1 and 3 respectively. The highest prevalence of musculoskeletal disorders from the Nordic questionnaire was for the lower back (52.6%). According to independent t-test was found a significant correlation between the scores of different parts of RULA and ROSA with the prevalence of musculoskeletal disorders in some areas of the body. The correlation coefficient (Pearson) between the final scores of RULA and ROSA methods was 0. 764. The results of the logistic regression model showed that the lower back had a significant relationship with gender, work history, BMI & final score of RULA and ROSA. Based on the results of both RULA and ROSA methods, it is necessary to further assessment required as soon as possible. The prevalence of low back pain is higher than other parts of the body. As for the relationship between the low back pain prevalence and the ROSA score in the chair and monitor, it is necessary to focus on improving these equipment, also these methods can be used as predictors of the MSDs Incidence Probability.

Job burnout is one of the most important factors affecting intent to leave among nurses and quality of care. The purpose of this study was to investigate the effect of demographic and organizational variables and also job stress on burnout among nurses.
This cross sectional study was done among 170 randomly selected nurses of a hospital in Shahroud. Data were collected using organizational demographic questionnaires, Nursing Stress Scale (NSS) and Maslach Burnout Inventory (MBI) questionnaire. The data analysis was performed by Pearson correlation and multiple logistic regression at 0.05 significant level using SPSS version 24.
Among the dimensions of occupational stress, conflict with peers and lack of support had the highest (11.79±4.45) and the lowest (3.77±1.64) average respectively. The highest average of burnout was belonged to emotional exhaustion (19.29±9.65). Emotional exhaustion had a significant correlation with lack of support (OR=1.91, CI=1.14-3.18), inadequate preparation (OR=2.01, CI=1.13-3.57) and conflict with physicians (OR=1.64, CI=1.45-1.92). In addition, the depersonalization was positively correlated with death and dying, lack of support and personal accomplishment had a negative and positive association with inadequate preparation and clinical experience.
The results of this study showed that improving some aspects of occupational stress, such as conflict with physicians, inadequate preparation, lack of support, death and dying, as well as improvement of shiftwork schedule might reduce perceived burnout.
