Abstract
Background: The prevalence of hypertension (HTN) among Iranian taxi drivers has not been well defined. This study aimed to determine the prevalence of HTN and to identify factors influencing its prevalence among Iranian taxi drivers in 2018.
Materials and Methods: This cross-sectional study was conducted on a total sample of 321 taxi drivers in Kermanshah province in 2018. The participants were classified into two groups, including the HTN group (SBP ≥ 140 or DBP ≥ 90) and the non-HTN group (SBP < 140 or DBP < 90). A self-administrated questionnaire, including questions about demographic information, medical history, and work-related factors was employed to collect data.
Results: According to the observations, 59.8% of the participants (192/321) suffered from HTN. According to the adjusted logistic regression model and the per one unit increase, there was significantly higher odds of HTN for age (odds ratio [OR] =1.04 and 95% confidence interval [CI] =1.02, 1.06) and work history (OR=1.08 and 95% CI=1.03, 1.13); in contrast, there was a lower risk of HTN for sleep duration (OR=0.83 and 95% CI=0.69, 0.99) and Work Days Per Week (WDPW) (OR=0.73 and 95% CI=0.57, 0.94). In the categorical analysis, a significantly higher risk of HTN was observed in the drivers with age ≥ 45, work history ≥ 5, Work Hours Per Day (WHPD) >10, WDPW ≤ 6, married, and poor economic status ≤ a 2-million Toman income per month.
Conclusions: This study introduces taxi drivers as a high-risk HTN group in the society. Hence, they should be informed of HTN risk factors and undergo regular checkups.

Abstract
Background: The mining industry is one of the most challenging environments in terms of safety issues. This study aimed to investigate occupational hazards as well as to perform a risk assessment in Golgohar mine, Sirjan, Iran, (2021).
Materials and Methods: A descriptive study was conducted on jobs of 763 mining workers. A study checklist was used to collect the data. Job safety analysis method was used to identify hazardous job activities. The risks were assessed using the failure modes and effects analysis technique. Data were analyzed using SPSS and appropriate statistical methods were applied.
Results: The major risks identified were the throwing and falling of objects (13.93%), the slipping and falling of workers from heights (12.61%), vehicle accidents (11.19%), and dust inhalation (9.53%). The risks of all jobs were unacceptable (RPNs > 100), yet they were reduced to an acceptable level by applying interventions.
Conclusion: By the timely identifying and controlling of hazards, potential mining accidents can be prevented. Performing regular risk assessments and the periodic training of workers can help achieve this goal.

Abstract
Background: Today, white-collar workers endure a variety of job stress. These factors can cause musculoskeletal problems, threaten aspects of occupational health, and reduce productivity. This study aimed to examine the effect of ergonomic training interventions on the musculoskeletal disorders (MSDs), job contents, work-life quality, and productivity in knowledge-based companies.
Materials & Methods: This study was conducted using quasi-randomized control trial method in 2019-2020. Four groups were included in the study: Ergonomics training, management training, combined interventions, and control group. The participants included 311 office workers who were randomly divided into four groups. Outcome measures were measured in follow-up periods. Repeated-measure ANOVAs was employed to analyze the results.
Results: Interventions performed on neck (P=0.001), right shoulder (P=0.001), left shoulder (P=0.002), and right upper extremity (P<0.025) were associated with significant improvements in MSDs. The interventions significantly increased the control and social support (P=0.001), though they did not affect the psychological demands. The quality of work-life increased significantly in the first month of follow-up, but the long-term trend showed a decline.
Conclusions: Combined interventions significantly increased absolute presenteeism. Simultaneous implementation of individual and managerial ergonomics revealed a greater impact on reducing MSDs and a broader impact on job content and presenteeism.
