Korean J Fam Med 2021; 42:390-394. [PMID: 34607415 PMCID: PMC8490170 DOI: 10.4082/kjfm.20.0217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 11/06/2020] [Accepted: 11/16/2020] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND The aim of this study was to evaluate the association between near work time and depression. METHODS Data of 1,551 workers aged 19-49 years from the sixth Korea National Health and Nutrition Examination Survey were examined. The Patient Health Questionaire-9 scores were used to screen for depression. Participants who scored a total of 10 or above, which is suggestive of the presence of depression, were classified as the depression group; the rest were classified as normal. The correlation between daily near work time and depression was analyzed using multivariate logistic analysis after adjusting for other sociodemographic and health behavior-related variables. RESULTS Multivariate logistic analysis found that workers with 3 or more hours of near work were more likely to report depression compared to the reference group who had 2 or fewer hours per day of near work (adjusted odds ratio, 2.471; 95% confidence interval, 1.062-5.747). CONCLUSION Longer near work time was associated with depression among South Korea's workers. Therefore, it is necessary to reduce near work time to prevent depression.

Abstract
Resumo Introdução: dor na coluna torácica diz respeito a traumas cumulativos envolvendo má postura, movimentos repetitivos e longos períodos na mesma posição. Objetivo: avaliar a prevalência de dor na coluna torácica e fatores associados em fumicultores no sul do Brasil. Métodos: estudo transversal cuja associação entre o desfecho e os fatores sociodemográficos e comportamentais, atividades laborais, cargas de trabalho e comorbidades foram examinadas pelo teste de Wald para heterogeneidade e tendência linear. A análise multivariável foi realizada utilizando modelo hierárquico e regressão de Poisson com variância robusta. Resultados: o estudo envolveu 2.469 indivíduos de ambos os sexos. A prevalência de dor na coluna torácica foi de 21,2%. Limpar equipamento para aplicação de agrotóxico, número de episódios de Doença da Folha Verde, sintomas respiratórios e transtornos psiquiátricos menores foram positivamente associados ao desfecho em ambos os sexos. Tabagismo e intoxicação por agrotóxicos foram associados ao desfecho entre as mulheres, enquanto escolaridade e passar varas com folhas de tabaco foram associados aos homens. Conclusões: reestruturação ergonômica, redução das cargas de trabalho, trocas de posição durante o turno de trabalho e mecanização do processo de trabalho são estratégias importantes para reduzir a exposição à nicotina, agrotóxicos e carga de trabalho ergonômica.

Abstract
Logging is one of the most dangerous occupations in the world. Logging tasks, whether they consist of operating a chainsaw, operating a mechanized harvester, or driving logging trucks, have an influence on the types of hazards and injuries among professional loggers. Using the Standardized Nordic Questionnaire, we investigated the 12-month period prevalence of musculoskeletal disorder symptoms (MSS) among professional loggers in the mountainous region of Montana. We also differentiated the prevalence of MSS based on logging system-type accounting for demographic and workplace covariates. Based on data from 743 professional loggers in Montana, loggers using conventional felling practices with chainsaws were more than twice as likely to report MSS (Odds Ratio (OR): 2.24 (1.07-4.69)) than those using mechanized logging equipment. In addition, increased MSS scores were associated with conventional harvesting systems, increased years of experience, and increased BMI. The active surveillance of MSS among professional loggers in Montana resulted in recommendations for safety interventions. The safety interventions included a greater mechanization of logging tasks and early career training on the heavy equipment used in logging operations.

Neck/shoulder discomfort due to visually demanding experimental near work is influenced by previous neck pain, task duration, astigmatism, internal eye discomfort and accommodation.

Abstract
Visually demanding near work can cause eye discomfort, and eye and neck/shoulder discomfort during, e.g., computer work are associated. To investigate direct effects of experimental near work on eye and neck/shoulder discomfort, 33 individuals with chronic neck pain and 33 healthy control subjects performed a visual task four times using four different trial lenses (referred to as four different viewing conditions), and they rated eye and neck/shoulder discomfort at baseline and after each task. Since symptoms of eye discomfort may differ depending on the underlying cause, two categories were used; internal eye discomfort, such as ache and strain, that may be caused by accommodative or vergence stress; and external eye discomfort, such as burning and smarting, that may be caused by dry-eye disorders. The cumulative performance time (reflected in the temporal order of the tasks), astigmatism, accommodation response and concurrent symptoms of internal eye discomfort all aggravated neck/shoulder discomfort, but there was no significant effect of external eye discomfort. There was also an interaction effect between the temporal order and internal eye discomfort: participants with a greater mean increase in internal eye discomfort also developed more neck/shoulder discomfort with time. Since moderate musculoskeletal symptoms are a risk factor for more severe symptoms, it is important to ensure a good visual environment in occupations involving visually demanding near work.

Abstract
BACKGROUND Causes of permanent work disability in the sheet metal industry are not well characterized. METHODS Pension records were used to compare causes of disability among sheet metal workers and the U.S. working population. Subgroup analysis examined the major causes of sheet metal worker disability. RESULTS Musculoskeletal disorders (MSDs), circulatory disease, and injuries were leading causes of sheet metal worker disability (47.2%, 13.7%, 10.9% of awards, respectively). Award distribution differed from the U.S. working population (P < 0.0001); MSDs and injuries accounted for higher proportions of sheet metal worker awards, particularly at spine, shoulder, and knee. CONCLUSIONS Higher proportions of awards caused by MSD or injury among sheet metal workers may reflect higher rates of work-related injuries and MSDs, a high likelihood of disability with construction work given the same impairment, or higher prevalence of other conditions in the general population. Prevention requires task-specific ergonomic innovations and proven participatory interventions.

Abstract
Aim To investigate if trapezius muscle activity increases over time during visually demanding near work. Methods The vision task consisted of sustained focusing on a contrast-varying black and white Gabor grating. Sixty-six participants with a median age of 38 (range 19–47) fixated the grating from a distance of 65 cm (1.5 D) during four counterbalanced 7-min periods: binocularly through −3.5 D lenses, and monocularly through −3.5 D, 0 D and +3.5 D. Accommodation, heart rate variability and trapezius muscle activity were recorded in parallel. Results General estimating equation analyses showed that trapezius muscle activity increased significantly over time in all four lens conditions. A concurrent effect of accommodation response on trapezius muscle activity was observed with the minus lenses irrespective of whether incongruence between accommodation and convergence was present or not. Conclusions Trapezius muscle activity increased significantly over time during the near work task. The increase in muscle activity over time may be caused by an increased need of mental effort and visual attention to maintain performance during the visual tasks to counteract mental fatigue.

Abstract
This study aimed to investigate the association between psychosocial factors (i.e., job demand, decision latitude, social support, physical environment, and personal risk factors), work-related musculoskeletal disorders (WRMDs), and productivity as measured by workers' perceived absenteeism. Data were collected from the selected administrative workers (administrative assistant) and analyzed using cross tabulation. The results indicate that all psychological factors are not significantly associated with WRMDs, except for the association between personal risk factors and hip/thigh disorders. Subsequently, WRMDs do not significantly contribute to explaining absenteeism. The managerial and research implications of this study are deliberately discussed.

Abstract
UNLABELLED The aim of this study was to determine whether results from the RSI QuickScan questionnaire on risk factors for arm, shoulder and neck symptoms can predict future arm, neck and shoulder symptoms in a population of computer workers. For this prospective cohort study, with a follow-up of 24 months, 3383 workers who regularly worked with a computer were approached. Generalised estimating equations (GEE) with 6, 12, 18 and 24 months time lags were used to determine whether high exposure was related to symptoms at follow-up. The results showed that high scores on 9 out of 13 scales, including previous symptoms, were significantly related to arm, shoulder and neck symptoms at follow-up. These results provide support for the predictive validity of the RSI QuickScan questionnaire. PRACTITIONER SUMMARY The results showed that high scores on 9 out of 13 scales, including previous symptoms, were significantly related to arm, shoulder and neck symptoms at follow-up. The RSI QuickScan questionnaire may be recommended as a tool in the identification of computer workers who should be targeted with interventions aimed at prevention of future symptoms.

Abstract
Background The musculoskeletal disorders in working population represent one of the most worrying work-related health issues at the present time and although the very great majority of available data on the subject focus on musculoskeletal disorders defined by anatomical site, a growing number of studies indicate the low prevalence of disorders strictly confined to a specific anatomical site. The objective of this study was to describe the prevalence and characteristics of multisite musculoskeletal symptoms (multisite MS) in a large French working population. Methods This study was performed on surveillance data of the cross-sectional survey (2002–2005) conducted by a network of occupational physicians in the working population of the Loire Valley region (from 20 to 59 years old). Data concerning MS were collected in the waiting room of the occupational physicians by means of the self-administrated standardized NORDIC questionnaire. Results The study population comprised 3,710 workers (2,162 men (58%) and 1,548 women (42%)) with a mean age of 38.4 years (standard deviation: 10.4 years). The prevalence of MS during the past 12 months was 83.8% with 95% confidence interval of [82.8-85.3] for men and 83.9% [82.0-85.7] for women. The prevalence of subacute MS (lasting at least 30 days) over the past 12 months was 32.8% [30.9-34.8] for men and 37.3% [34.9-39.7] for women. Two-thirds of workers reported MS in more than one anatomical site and about 20% reported MS lasting at least 30 days in more than one anatomical site. The anatomical sites most frequently associated with other MS were the upper back, hip, elbow and neck. The majority of these multisite MS were widespread, involving at least two of the three anatomical regions (upper limb, axial region and lower limb). Conclusions The frequency and extent of multisite MS reported by workers are considerable. Further research must be conducted in this field in order to provide a better understanding of the characteristics and determinants of these multisite MS.

Abstract
INTRODUCTION The purpose of this study was to identify and compare individual behavioral and psychophysiological responses to workload demands and stressors associated with the reporting of musculoskeletal symptoms with computer work. Evidence is growing that the prevalence of musculoskeletal symptoms increases with longer hours of computer work and exposure to psychosocial stressors such as high workloads and unrealistic deadlines. Workstyle, or how an individual worker behaves in response to such work demands, may also be an important factor associated with musculoskeletal symptoms in computer operators. METHOD Approximately 8,000 employees of the Australian Public Service were invited to complete an on-line survey if they worked with a computer for 15 or more hours per week. The survey was a composite of three questionnaires: the ASSET to measure perceived organizational stressors, Nordic Musculoskeletal Questionnaire to measure reported prevalence of musculoskeletal symptoms and additional questions to measure individual work behaviors and responses. RESULTS 934 completed surveys were accepted for analyses. Logistic regression was used to identify significant behavioral and work response predictors of musculoskeletal symptoms. Reporting of heightened muscle tension in response to workload pressure was more strongly associated, than other physical behavioral factors, with musculoskeletal symptoms for all body areas, particularly the neck (OR = 2.50, 95% CI: 2.09-2.99). CONCLUSIONS Individual workstyles in response to workload demands and stressors, including working with heightened muscle tension and mental fatigue, were significantly associated with musculoskeletal symptoms. Future risk management strategies should have a greater focus on the identification and management of those organizational factors that are likely to encourage and exacerbate adverse workstyles.

Abstract
BACKGROUND Musculoskeletal disorders are the most common cause of disability in many industrial countries. Recurrent and chronic pain accounts for a substantial portion of workers' absenteeism. Neck pain seems to be more prominent in the general population than previously known. OBJECTIVES To determine the effectiveness of workplace interventions (WIs) in adult workers with neck pain. SEARCH STRATEGY We searched: CENTRAL (The Cochrane Library 2009, issue 3), and MEDLINE, EMBASE, CINAHL, PsycINFO, ISI Web of Science, OTseeker, PEDro to July 2009, with no language limitations;screened reference lists; and contacted experts in the field. SELECTION CRITERIA We included randomised controlled trials (RCT), in which at least 50% of the participants had neck pain at baseline and received interventions conducted at the workplace. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed risk of bias. Authors were contacted for missing information. Since the interventions varied to a large extend, International Classification of Functioning, Disability and Health (ICF) terminology was used to classify the intervention components. This heterogeneity restricted pooling of data to only one meta-analysis of two studies. MAIN RESULTS We identified 1995 references and included10 RCTs (2745 workers). Two studies were assessed with low risk of bias. Most trials (N = 8) examined office workers. Few workers were sick-listed. Thus, WIs were seldom designed to improve return-to-work. Overall, there was low quality evidence that showed no significant differences between WIs and no intervention for pain prevalence or severity. If present, significant results in favour of WIs were not sustained across follow-up times. There was moderate quality evidence (1 study, 415 workers) that a four-component WI was significantly more effective in reducing sick leave in the intermediate-term (OR 0.56, 95% CI 0.33 to 0.95), but not in the short- (OR 0.83, 95% CI 0.52 to 1.34) or long-term (OR 1.28, 95% CI 0.73 to 2.26). These findings might be because only a small proportion of the workers were sick-listed. AUTHORS' CONCLUSIONS Overall, this review found low quality evidence that neither supported nor refuted the benefits of any specific WI for pain relief and moderate quality evidence that a multiple-component intervention reduced sickness absence in the intermediate-term, which was not sustained over time. Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. There is an urgent need for high quality RCTs with well designed WIs.

Abstract
BACKGROUND Neck/Shoulder pain is linked to movement repetition, awkward postures, prolonged maintenance of static postures, and muscular fatigue. Studies have examined the influence of pain and fatigue on movement characteristics, but few reported multi-dimensional adaptations to movement repetition. We compared the adaptations measured in three-dimensions during a repetitive reaching task in persons with chronic neck/shoulder pain and healthy subjects. METHODS A shoulder-injured group (intensity >3/10, duration >3 consecutive months) and an age-sex-matched control group (n=16 in each) performed a repetitive reaching task to voluntary termination. Kinematics, kinetics, heart rate and muscle activity were recorded throughout. Power output on a 10-s pushing/pulling task was assessed pre- and post-reaching. Group comparisons were made in absolute time and at task end. FINDINGS Control subjects performed the task 55% longer than the pain group; yet, both groups demonstrated task-related increased heart rate (6 beats per minute) and decreased power output (6 W). Throughout the task, the pain group demonstrated: higher supraspinatus activity, and less elbow flexion and endpoint movement. The control group increased movement amplitude of the endpoint, elbow, and shoulder, while the pain group moved the shoulder less and increased center of mass excursion to maintain the task. INTERPRETATION Both groups adapted to the task in unique ways. The control group continually increased elbow and endpoint range of motion, bringing the arm closer to the targets, possibly to prolong task performance. The pain group used a fixed, en block arm strategy, likely to reduce the load on the injured structures; however, this may place other structures at risk for pain and injury.

Abstract
BACKGROUND To assess the intersection of work demands, chronic medical and musculoskeletal conditions, aging, and disability, we initiated a longitudinal study of construction roofers who were current union members between the ages of 40 and 59. METHODS Participants were asked about the presence of medical conditions and musculoskeletal disorders; the Work Limitations Questionnaire, the SF-12, and other validated assessments of social and economic impact of injury were included. RESULTS Factors at baseline that predicted leaving for a health-related reason were older age, lower physical functioning, work limitations, and having missed work. Those who left roofing for a health-related reason were much more likely to have a lower economic score at the 1 year interview. CONCLUSIONS Medical and musculoskeletal conditions are strongly associated with work limitation, missed work, and reduced physical functioning; these factors are also associated with premature departure from the workforce.

Abstract
OBJECTIVES Few prospective studies have evaluated outcomes of workers with self-reported symptoms of upper extremity musculoskeletal disorders (UEMSD). The objective was to study the three-year outcomes of workers with self-reported symptoms, with or without a positive physical examination. METHODS In 1993-4, 598 subjects highly exposed to repetitive work filled out a Nordic-style questionnaire. They underwent a standardised physical examination at that time and again in 1996-7 by the same occupational physician. The three-year outcomes (based on physical examination) of workers with a self-administered questionnaire positive at baseline for UEMSD, with or without a positive physical examination, were studied. RESULTS The three-year incidence rate was 44.1%; one third of these incident cases had self-reported symptoms in 1993-4. Workers with a positive questionnaire had a significantly higher risk of UEMSD at physical examination three years later (80.1% UEMSD cases with positive questionnaires n = 354, vs 44.2% cases without positive questionnaires n = 69, p<0.001). Moreover, workers with positive questionnaires but without UEMSD diagnosed in 1993-4 (n = 177) also had a significantly higher risk of UEMSD at physical examination three years later (60.5% cases with positive questionnaires n = 26, vs 38.8% cases without positive questionnaires n = 52, p = 0.01). Results were similar when gender and age were taken into account. CONCLUSION Workers highly exposed to repetitive movements have a high risk of developing UEMSD and should be followed closely in surveillance programmes. Workers with self-reported symptoms without UEMSD diagnosed in physical examination represented only one third of new cases three years later. However, their risk of developing UEMSD was significantly increased, compared with those without symptoms.

Abstract
OBJECTIVE To explore the possible role of ultrasonography in case definitions for epidemiological studies of work-related wrist tenosynovitis. METHODS Clinical and ultrasonography (7.5 MHz linear probe) data systematically collected from meat workers (n = 128) with biomechanical exposure characterisation were analysed. The diagnostic accuracy of different combinations of potentially relevant ultrasonography findings (nonhomogeneity, thickening and anechoic halo) was evaluated using symptomatology as a reference standard. The concordance between ultrasonography findings and symptoms was then analysed. RESULTS Analysis of wrist biomechanical exposure was suggestive of increased prevalence of musculoskeletal disorders. Using symptoms as a reference standard, each of the three ultrasonography findings (and their combinations) showed good specificity (> or =85%) accompanied by low sensitivity (<60%); the positive likelihood ratio for at least two findings was 4.1. kappa Values (95% confidence intervals) between symptoms and different sets of ultrasonography findings were as follows: for non-homogeneity, kappa = 0.31 (0.19 to 0.43); at least one finding, kappa = 0.28 (0.16 to 0.40); at least two findings, kappa = 0.32 (0.20 to 0.44); all p<0.01. CONCLUSION The use of ultrasonography in symptomatic subjects could contribute to a more specific epidemiological case definition of wrist tenosynovitis. The results of this study could help orient future research in this direction.

Abstract
BACKGROUND Somatization (a tendency to report distress from somatic symptoms) is a little studied, but potentially important, confounder and effect modifier in occupational studies of musculoskeletal disease. AIMS To assess the role of somatization as a risk factor for disabling regional pain. METHODS A questionnaire was mailed to 4998 subjects of working age. Questions were asked about chronic and disabling pain in the past 12 months affecting the arm, low back, knee or combinations of these sites. Distress from physical symptoms was assessed using elements of the Brief Symptom Inventory and mental well-being was assessed using the short-form 36 (SF-36). Associations were examined by modified Cox regression and expressed as hazard ratios (HRs) with 95% confidence intervals (CI). RESULTS Among 2632 responders, 24% reported chronic pain and 25% disabling pain at one or several sites. Risk of chronic or disabling pain increased strongly according to the number of somatic symptoms reported as bothersome. For example, the HR for chronic upper limb pain in those distressed by > or =2 somatic symptoms in the past 7 days versus none was 3.9 (95% CI 2.9-5.3), and that of disabling upper limb pain was 5.8 (95% CI 4.1-8.3). Similar patterns were found for the low back and knee, and there was a gradient of increasing risk according to the number of sites with disabling pain. In comparison, associations with SF-36 mental well-being score were weaker. CONCLUSION Somatizing tendency should be evaluated as a possible confounder or effect modifier in studies of occupational risk factors for musculoskeletal pain.
