Objectives Both physical and psychosocial risk factors contributing to musculoskeletal disorders occur in the professional nursing group, and previous literature suggested that their interaction may increase the risk of musculoskeletal pain among nurses. The aim of the study was to examine perceived workload and stress as well as physical findings and musculoskeletal complaints in nurses. Material and Methods The participants consisted of 42 female nurses, age range 23–60 years. They marked on a pain drawing the site/sites that was/were painful at the moment of testing, its duration and intensity. Thereafter they were examined using the movement and respiration domains from the Global Physiotherapy Examination (GPE). Furthermore, a subjective workload measure was made using the paper version of the National Aeronautics and Space Administration Task Load Index and stress was assessed using the Perceived Stress Questionnaire. Results Almost the entire study group declared that pain experienced in at least 1 location was chronic, i.e., had lasted ≥1 year (97%). The most frequent locations of pain were low back (22.4%) and cervical/head (21.6%) regions. In the GPE, most scores indicated restricted and reduced movement, with the subdomain flexibility having the highest deviation from the predefined standard. Furthermore, the results indicated hampered respiration, especially visible in standing position. Out of all workload scores, the highest was obtained for temporal demand. Perceived stress level was found to be moderate and significantly associated to chronic chest/ thoracic pain. Interestingly, the compression of thorax test positively correlated with mental (r = 0.42, p < 0.05) and physical demand (r = 0.35, p < 0.05), whereas the elbow drop test and temporal demand correlated negatively (r = –0.37, p < 0.05). Conclusions To sum up, the majority of nurses participating in this study had long-lasting pain and limited flexibility of the body and hampered respiration, which both may enhance intensity of experienced musculoskeletal pain.

Objectives: This study aims to assess muscle fatigue for kitchen workers during various tasks in a kitchen. Material and Methods: This study consists of 2 phases: a) surface electromyography (EMG) to determine muscle fatigue of trapezius and erector spinae muscles bilaterally for 12 healthy male volunteers during 30 min of Indian flatbread (chapati) preparation, b) self-administered questionnaire study after 30 min preparation to determine the impact on performance. Results: Surface EMG results show that the right trapezius muscle had significantly higher fatigue during kneading, rolling and roasting tasks. Similarly, right erector spinae muscle showed significantly higher fatigue during rolling and roasting tasks. Conclusions: Both phases of the study conclude that, even though the dynamic postural adjustment may reduce fatigue during the work schedule; the combination of risk factors like the repetitive task, forceful exertion and prolonged standing during working results in a high risk of developing muscle fatigue.

Objectives The study aims to assess the impact of municipal waste loading occupation upon developing musculoskeletal disorders (MSDs) and thereby disabilities among waste loaders. Additionally, the study has identified the potential risk factors raising MSDs and disabilities. Material and Methods A cross-sectional case-control design survey was conducted in 6 out of 24 municipal wards of Mumbai during March–September 2015. The study population consisted of municipal waste loaders (N = 180) and a control group (N = 180). The Standardized Modified Nordic questionnaire was adopted to measures the MSDs and thereby disabilities in the past 12 months. A Propensity Score Matching (PSM) method was applied to assess the impact of waste loading occupation on developing MSDs and disabilities. Results Waste loaders had a significantly higher risk of developing MSDs as well as disabilities than the control group particularly for low back, hip/ thigh upper back and shoulder. Propensity Score Matching results revealed that the MSDs were significantly higher among waste loaders for hip/thigh (22%), low back (19%), shoulder (18%), and upper back (15%) than matched control group. Likewise, MSDs-related disabilities were found to be significantly higher among waste loaders for low back (20%), hip/ thigh (18%) upper back (13%) and shoulder (8%) than the control group. Duration of work, substance use and mental health were found to be the potential psychosocial factors for developing the risk of MSDs and disabilities. Conclusions The municipal waste loading occupation raised the risk of MSDs and related disabilities among waste loaders compared to the control group. The preventive and curative measures are strongly recommended to minimize the burden of MSDs and disabilities. Int J Occup Med Environ Health 2017;30(6):875–886

The purpose of this research was to study factors affecting musculoskeletal disorders. The sample population of the study was 528 factory workers from the frozen food industry, as well as a controlled group of 255 office workers. The samples were collected during interviews using the Nordic questionnaire to assess musculoskeletal disorders, and to assess the risk by the rapid upper limb assessment and rapid entire body assessment techniques. The findings of the study were that most symptoms were found in the dissecting department, higher than in the controlled group. The details of the symptoms were, accordingly: elbow pain (adjusted odds ratio, 35.1; 95% CI [17.4, 70.9]). Regarding the risk of alcohol drinking, workers were exposed to more risks when alcohol was consumed. It is suggested that workers’ health should be monitored regularly. People who work in a cold environment should be encouraged to wear body protection and to avoid drinking.

Aim: Several studies suggest that coal miners are under risk of severe health problems such as cardiovascular, pulmonary, neurological, renal, hematological and musculoskeletal disorders. However, there are limited data on biochemical changes in underground workers. In our study we aimed to evaluate the association between serum homocysteine (Hcy), vitamin B12, cystatin C and folate levels in the blood of underground coal miners. Materials and Methods: Eighty one coal miners who work as underground or surface workers were recruited into our study. The study population was divided into two groups: the surface worker group (control group, n=33) and the underground worker group (n=48). The folate, vitamin B12, Hcy, cystatin C levels and body mass indexes (BMI) of both groups were measured and compared. Serum folate, Hcy and vitamin B12 levels were measured with a competitive chemiluminescence immunassay. Serum levels of cystatin C were determined by the latex particle-enhanced turbidimetric method using a cystatin C kit. Urea values were measured with a kinetic method on an automated analyzer. Results: There were no statistically significant differences between the underground workers and surface workers in the urea, cystatin C and vitamin B12 levels. High serum Hcy levels and low folate levels were found in underground workers compared with those in surface workers. The correlation between Hcy and folate levels was also statistically significant. Similarly, there was also a significant correlation between Hcy and vitamin B12, and between Hcy and cystatin C levels. Conclusions: Elevated Hcy levels may be associated with underground working but further research is necessary to understand the relation between elevated Hcy and increased prevalence of health problems in coal miners.
