Abstract
Introduction: While great efforts have been made to determine the quality of life in
hospital staffs, few studies have been conducted to identify the effective
factors on the quality of life of these employees. The purpose of the present
study was to investigate the relationship between workload and quality of life
in hospital personnel.
Material and Methods: In this descriptive-analytical study, 200 staffs were selected randomly
from two large hospitals of Tehran University of medical sciences (Imam
Khomeini and Shariati hospitals). The data collecting tools were three
questionnaires including demographic characteristics,
quality of life (SF-36), and NASA-TLX workload. SPSS software (version 18.0)
was used to analyze the data by descriptive statistics, and Pearson and
Spearman correlation tests.
Results: Based on the
findings of the study, the mean total scores of the quality of life and the
workload were 50±18 and 69.7±13.9, respectively. The results revealed
significant reduction in all dimensions of quality of life in nurses compared
with laboratory and operating room staffs. Meanwhile the nurses’ workload
scores were higher than the two aforementioned groups (p = 0.001). Moreover,
there was a significant inverse relationship between workload and quality of
life in hospital staffs (P=0.004, r = -.306).
Conclusion: The
results of this study highlight the role of managers and supervisors in the
implementation of efficient interventions for improving the quality of life and
workload. Therefore, further researches are required to identify other factors
that affect the quality of life and workload in hospital staffs.

Abstract
Introduction: Three methods of OCRA Index, Strain Index and ACGIH HAL are proposed to assess risk factors of upper extremity musculoskeletal disorders. These methods are important in work environments to evaluate musculoskeletal disorders. Thus the aim of this study is to determine the correlation between the results of the above mentioned methods.
Materials and Methods: In this cross - sectional study, a total of 150 job tasks studied in four industries . For each task, not only video taping was used to record the duration of a full cycle but also tasks were evaluated according to instructions. The correlation coefficient and the coefficient of agreement were analysed using SPSS16 and R software.
Results: Correlation between the results of risk assessment methods OCRA and SI for right and left hand, were acceptable correlation (0.751) and (0.726) respectively. Also the result of agreement between the methods OCRA and HAL for right and left hands, were (0.526) and (0.595) respectively.
Conclusion: This study showed that none of the two methods do not fully agree. One of the source of differences is the number and types of variables and their effects on the final score of the methods.

Abstract
Background: One of the main problems in the occupational workplace is musculoskeletal disorders. Quality of life is a multidimensional concept, including the ability of performance, health and mental statues that important factors such as physical, psychological, social relationships and personal attitude influence on quality of life .The aim of current study is assessment of impact of musculoskeletal disorders and physical activity on quality of life in automobile factory workers.
Materials and Methods: In this study, from 453 automobile factory workers, 140 workers participated. In order to determine musculoskeletal disorders, quality of life and physical activity, Nordic musculoskeletal questionnaire, quality of life questionnaire (SF 36) and physical activity questionnaire were used respectively. Data were analyzed using SPSS-16 software with descriptive analysis and Pierson correlation analysis.
Result: The results showed that the between physical function, activity limitation due to physical problems, bodily pain, vitality, public health and fatigue with musculoskeletal disorders were statistically significant correlation (P< 0.05). Between regular physical activity and musculoskeletal disorders and consequent with quality of life obtained significant correlation.
Discussion: Physical activity (exercise) increases worker fitness and reduces probability risk of musculoskeletal disorders and increase quality of life.

Abstract
Objectives: Traffic accidents are one of the leading causes of death among pregnant women. One of the investment for maternal and neonatal health is targeted interventions to increase maternal safety to prevent traffic accidents. Therefore, this study was conducted with the aim of identifying and categorizing different types of safety interventions to reduce traffic accidents among pregnant women.
Methods: The study was a systematic review. Intervention articles were searched from Persian databases, such as Magiran, Iran Medex and SID and English scientific information databases, such as PubMed, Cochrane, Sciencedirect, Embase, Science of Web and Scopus. All identified articles were collected by one person using Endnote software. The full text of the articles was then reviewed by two researchers and the articles that met the entry criteria were identified. Other articles were added to the previous collection of articles using Forward Citation and Backward Citation Reviews. The EPHPP instrument was used to assess the quality of the studies.
Results: The initial search resulted in finding 5329 article abstracts. Finally, two intervention studies were selected for evaluation in this study. One study used an educational/behavioral approach and the other used an engineering/approach. Both studies reported that they had produced significant changes in the desired outcome of seatbelt use in pregnant women. The quality of one study was rated as poor and the other as moderate.
Conclusion: Safety interventions to reduce traffic accidents among pregnant women have been tested only to a very limited extent worldwide. It seems that there is still much room for study in the field of safety interventions to reduce traffic accidents among pregnant women.
