Technical field measurements of muscular workload during stocking activities in supermarkets: cross-sectional study.

ABSTRACT: Multiple studies have reported high prevalence of musculoskeletal disorders among supermarket workers. Technical field measurements can provide important knowledge about ergonomic risk factors for musculoskeletal disorders in the physical working environment, but these measurements are lacking in the supermarket sector. Therefore, using wearable electromyography and synchronous video recording in 75 supermarket workers, this cross-sectional study measured muscular workload during stocking activities in six different types of general store departments and during the thirteen most common work tasks across five different supermarket chains. Our results showed that muscular workload varies, especially for the low-back muscles, across (1) supermarket chains, (2) departments, and (3) specific stocking activities. Highest workloads of the low-back and neck/shoulders were seen in the fruit and vegetables department and during heavy, two-handed lifts of parcels (especially without using technical aids). In conclusion, physical work demands during supermarket stocking activities differ between chains, departments, and work tasks. These results can be used by company representatives and work environment professionals to specifically address and organize the stocking procedures to reduce the muscular workload during supermarket stocking.

Project description:BACKGROUND:Construction work frequently involves heavy physical work, and a reduction of the physical workload should have high priority. Technological development has made it possible to obtain field measurements with surface electromyography (sEMG), kinematics measured with inertial measurement units (IMUs), and video recordings. However, no studies have used these methods simultaneously to detect situations with excessive physical workload (events) during a working day. Thus, knowledge about these specific events may combat work-related risk factors. Participatory ergonomics (PE) has shown promising results, but whether it can be used as a tool to reduce the physical workload during construction work remains unknown. OBJECTIVE:This cluster randomized controlled trial investigated whether a PE intervention with technical measurements consisting of IMUs, sEMG, heart rate monitoring, and video recordings of physical workload could reduce the number of events with excessive physical workload during a working day. Furthermore, other outcomes were obtained from questionnaires. METHODS:A total of 80 male full-time construction workers (aged 19 to 67 years) were randomized at the cluster level (gang) to a PE intervention consisting of 3 workshops (7 gangs and 32 workers) or to a control group (8 gangs and 48 workers). The physical workload was recorded by technical measurements, that is, IMUs, sEMG, heart rate monitoring, and video recordings during a full working day at baseline and 3 and 6 months' follow-up. On the basis of the technical measurements, a custom-made computer program detected the situations (events) where the construction workers were exposed to excessive physical workload and used in the intervention. Differences in the number of events from baseline to follow-up between intervention and control were evaluated using linear mixed models (intention-to-treat), with individual nested in cluster as a random factor. Furthermore, questionnaires were filled out on test days. RESULTS:The results of the primary outcome showed no change in the number of events with excessive physical workload. However, compared with the control group, the other outcomes showed decreased general fatigue after a typical working day (P=.001) and increased influence on own work (P=.04). CONCLUSIONS:This PE intervention with technical measurements did not reduce the number of events with excessive physical workload during construction work. However, the intervention led to decreased general fatigue and increased influence on own work.

Project description:BackgroundPractice nurses have a key role within UK general practice, especially since the 2004 GMS contract. This study aimed to describe that role, identify how professionally supported they felt and their career intentions. An additional aim was to explore whether they felt isolated and identify contributory factors.MethodsA cross-sectional questionnaire survey in one large urban Scottish Health Board, targeted all practice nurses (n = 329). Domains included demographics, workload, training and professional support. Following univariate descriptive statistics, associations between categorical variables were tested using the chi-square test or chi-square test for trend; associations between dichotomous variables were tested using Fisher's Exact test. Variables significantly associated with isolation were entered into a binary logistic regression model using backwards elimination.ResultsThere were 200 responses (61.0% response rate). Most respondents were aged 40 or over and were practice nurses for a median of 10 years. Commonest clinical activities were coronary heart disease management, cervical cytology, diabetes and the management of chronic obstructive pulmonary disease. Although most had a Personal Development Plan and a recent appraisal, 103 (52.3%) felt isolated at least sometimes; 30 (15.5%) intended leaving practice nursing within 5 years.Isolated nurses worked in practices with smaller list sizes (p = 0.024) and nursing teams (p = 0.003); were less likely to have someone they could discuss a clinical/professional (p = 0.002) or personal (p < 0.001) problem with; used their training and qualifications less (p < 0.001); had less productive appraisals (p < 0.001); and were less likely to intend staying in practice nursing (p = 0.009). Logistic regression analysis showed that nurses working alone or in teams of two were 6-fold and 3.5-fold more likely to feel isolated. Using qualifications and training to the full, having productive appraisals and planning to remain in practice nursing all mitigated against feeling isolated.ConclusionsA significant proportion of practice nurses reported feeling isolated, at least some of the time. They were more likely to be in small practices and more likely to be considering leaving practice nursing. Factors contributing to their isolation were generally located within the practice environment. Providing support to these nurses within their practice setting may help alleviate the feelings of isolation, and could reduce the number considering leaving practice nursing.

Project description:OBJECTIVES:Chinese neurosurgery has made great progress during the past decades; yet, little is known about the working status of neurosurgeons. This study aimed to evaluate the difference between academic and non-academic neurosurgeons, focusing on their professional burnout, job satisfaction and work engagement. DESIGN:Cross-sectional nationwide survey. STUDY SETTING:The survey was conducted in China between 2017 and 2018. PARTICIPANTS:A total number of 823 academic neurosurgeons and 379 non-academic neurosurgeons participated in this study. OUTCOME MEASURES:Professional burnout, job satisfaction and work engagement were assessed using the Maslach Burnout Inventory, the Job Descriptive Index and the Utrecht Work Engagement Scale, respectively. RESULTS:The majority of respondents were male (92.93%), less than 45 years old (85.27%) and married (79.53%). Chinese neurosurgeons worked 63.91±11.04 hours per week, and approximately 45% experienced burnout. Compared with non-academic respondents, academic neurosurgeons had longer working hours (p<0.01), higher income (p<0.01) and were less willing to get married (p<0.01). In addition, they showed a lower degree of burnout (p<0.01), a higher level of job satisfaction (p<0.01) and were more enthusiastic at work (p=0.015). Multivariate regression analyses indicated that divorced (OR 7.02, 95% CI 2.37 to 15.08) and workplace violence (OR 1.52, 95% CI 1.18 to 2.24) were associated with burnout for both academic and non-academic respondents. Long working hours (≥71 hours per week) and low annual income (<1 00 000 RMB) were risk factors for burnout among academic neurosurgeons. For non-academic neurosurgical surgeons (age 36-45 years), working as attending doctors, serving in public hospitals and having the first house-living child were all closely related to the incidence of burnout. CONCLUSION:Chinese neurosurgeons are under significant stress particularly for the non-academic neurosurgeons. Offering better opportunities for training, promotion, higher income and safer working environments could be solutions to relieve burnout and improve career satisfaction and engagement.
