Postural Loading Assessment in Assembly Workers of an Iranian Telecommunication Manufacturing Company

Background. Changes in industries and work practices have coincided with work-related musculoskeletal disorders (MSDs). This study was conducted to determine the prevalence of MSDs and to assess postural loading in assembly workers of an Iranian telecommunication manufacturing company. Methods. Data were collected from 193 randomly selected workers in 4 units of the company. The Nordic musculoskeletal disorders questionnaire and the UBC ergonomic checklist were used as data collection tools. Loading on the upper body assessment (LUBA) was used to assess postural loading. Results. Lower back symptoms were the most prevalent problems among the workers (67.9%). LUBA showed that most assembly workers (94.3%) had experienced considerable and high postural loading (postural load index, PLI > 5). Regression analyses revealed that lighting, rotation, contact stress, repetition, gender and age were factors associated with symptoms. Conclusion. Work-related MSDs occurred at a high rate among workers. Postural loading requires consideration. Any ergonomic intervention should focus on eliminating ergonomic factors associated with symptoms.     

Occupational Exposure to Natural UV Radiation and Premature Skin Ageing

The skin is the part of the human body most vulnerable to ultraviolet (UV) radiation. The spectrum of the negative effects of UV radiation on the skin ranges from acute erythema to carcinogenesis. Between these extreme conditions, there are other common skin lesions, e.g.,photoageing. The aim of this study was to assess the skin for signs of photoageing in a group of 52 men occupationally exposed to natural UV radiation. There were 2 types of examinations: an examination of skin condition (moisture, elasticity, sebum, porosity, smoothness, discolourations and wrinkles) with a device for diagnosing the skin, and a dermatological examination. The results of both examinations revealed a higher percentage of skin characteristics typical for photoageing in outdoor workers compared to the general population.     

Investigation of work-related musculoskeletal disorders among male kitchen workers in South India

Objective. This study aims to quantify the prevalence of work-related musculoskeletal disorders (MSDs) and risks among male kitchen workers in the catering industry. Method. Data were collected with the help of the Nordic musculoskeletal questionnaire and by direct observations. Results. In total, 114 male kitchen workers from various hostels of a college in South India were considered for this study. The average age and mean years of employment of the workers are 26.4 (SD 7.7) and 7.8 respectively. The statistical analysis carried out reveals that 67.5% of male kitchen workers reported MSDs during the past 12 months. The highest prevalence rate has been found in the lower back (65.8%) and shoulder region (62.3%). Among different categories of kitchen work analyzed, it is evident that chief cooks suffer more from MSDs (79.2%) than assistant cooks (74.3%) and kitchen aides (30.0%). Workers in the older group, i.e., ≥41 years, and workers with 6–10 years of experience suffer with higher risk of MSDs, i.e., 93.9% and 87.5%, respectively. Conclusion. The male kitchen workers who participated in this research were found to possess both MSDs and ergonomic hazards.     

Multiple dimensions of work-related risk factors and their relationship to work ability among industrial workers in Iran

Objectives. The present study was designed to investigate the simultaneous effects of physical, psychosocial and other work-related risk factors on the work ability index (WAI) score among industrial workers. Methods. This study used a cross-sectional design with a questionnaire survey. A total of 280 workers were included in the study. Data were collected using three questionnaires including the Persian version of the WAI, the Persian version of the job content questionnaire and an author-developed measure (to assess work-related factors, health-related factors and socio-demographic characteristics). Results. The majority of the participants were young, but they had poor WAI scores (mean 37.3?±?6.4) and 44.3% of them had poor or moderate work ability. Occupational accidents and injuries were found to be the strongest predictors of WAI scores. Additionally, there was a strong association between WAI scores and supervisor support, skill discretion, occupational training, sleep quality, work nature and educational level. Conclusions. Intervention programs should focus on improving supervisor support, sleep quality, job skills and knowledge and on decreasing physical and mental work demands. Additionally, implementing a comprehensive occupational health and ergonomics program for controlling and reducing hazardous working environments and occupational injury rates should be considered.

煤工尘肺患者生存质量与家庭功能和社会支持的关系研究

为了解煤工尘肺患者的生存质量的现状及其与家庭功能和社会支持之间的关系,采用SF-36量表、家庭功能评定量表和社会支持评定量表对212名煤工尘肺患者进行问卷调查。单因素分析显示,煤工尘肺患者在SF-36量表的躯体疼痛、总体健康、活力、情感职能、精神健康5个维度的得分与对照组的差异有统计学意义（p〈0.05）。生存质量得分与家庭功能得分呈负相关,生存质量得分与社会支持得分呈正相关。以生存质量得分为因变量,以家庭功能和社会支持的分量表得分为自变量进行多元逐步回归分析显示,生存质量的影响因素为社会支持利用度、家庭功能的总的功能、情感介入、社会支持的客观支持和问题解决。研究结果表明,煤工尘肺患者生存质量较低,与其家庭功能和社会支持有密切关系,需要从家庭功能和社会支持采取综合措施,提高煤工尘肺患者的生存质量。     

农民工职业危害防护需求意愿调查分析

为了调查农民工职业危害防护的具体需求意愿及他们对企业职业危害管理现状的认知,分析农民工职业危害防护需求意愿与农民工职业危害防护行为之间的关系。采用问卷调查的定量调查方法进行调查。调查对象中男性农民工409人,女性农民工157人。参与问卷调查的农民工,均接触一种及以上的职业性有害因素。调查内容包括了解公司预防和控制职业病的政策,参与公司的职业危害管理决策,实施的职业性健康安全培训、健康监护、个人防护用品的使用等预防和控制职业病的管理措施等方面,本次调查显示,农民工对于预防职业危害表现出强烈的需求愿望,且对企业的职业危害防护现况表示了不满,倾向于采取极端的行为维护自身的健康权益。但另一方面,农民工实际参与企业职业危害防护的行为率较低,与他们的需求意愿相比有明显的差距。     

Evaluating repeated patient handling injuries following the implementation of a multi-factor ergonomic intervention program among health care workers

Objective

The objective of this study was to evaluate repeated patient handling injuries following a multi-factor ergonomic intervention program among health care workers.

Methods

This was a quasi-experimental study which had an intervention group and a non-randomized control group. Data were collected from six hospitals in Saskatchewan, Canada from September 1, 2001 to December 1, 2006.

Results

A total of 1,480 individuals who had a previous injury were eligible for the study. Medium and small size hospitals in the intervention group had significantly fewer repeated injuries than in the control group. Multivariate analysis showed that the intervention group had 38.1% lower odds of having repeated injury compared to the control group, after adjusting for hospital size.

Conclusions

The work-related repeated injury after a multi-factor intervention program was reduced. The synergistic relationships between components of multi-factor intervention and applicability of injury prevention programs to different settings need to be further explored.

Impact on Industry

Implementing a multi-factor program with the right equipment and training can lower the risk of injury among health care workers.     

Antecedents and outcomes of contingent workers' attitudes toward their temporary help services firm: A unit level longitudinal investigation

This study explored the unit‐level antecedents and outcomes of contingent workers' attitudes toward their temporary help services (THS) firm. It was proposed that (a) client‐orientation levels of the THS firm's full‐time staff would influence the level of support received by contingent workers, (b) staff supportiveness would be reciprocated by these workers in the form of favorable firm‐directed attitudes, and (c) contingent workers' attitudes toward the THS firm would influence two unit‐level outcomes—client reported service failure, and voluntary turnover rates of THS staff. Support was found for all the hypothesized relationships in a longitudinal study utilizing survey data gathered from 1324 full‐time employees, 570 contingent workers, and 1951 clients; and archival data on staff turnover from 46 strategic business units (SBUs) of a THS firm. These results are discussed within the context of employee–organization relationship (EOR), contingent workforce, and service management literatures. Copyright © 2010 John Wiley & Sons, Ltd.
