Ergonomic principles at the computer workstation may reduce the occurrence of work related injuries commonly associated with intensive computer use. A program implemented in 2001 by an occupational therapist and a physical therapist utilized these preventative measures with education about ergonomics, individualized evaluations of computer workstations, and recommendations for ergonomic and environmental changes. This study examined program outcomes and perceived effectiveness based on review of documents, interviews, and surveys of the employees and the plant manager. The program was deemed successful as shown by 59% of all therapist recommendations and 74% of ergonomic recommendations being implemented by the company, with an 85% satisfaction rate for the ergonomic interventions and an overall employee satisfaction rate of 70%. Eighty-one percent of the physical problems reported by employees were resolved to their satisfaction one year later. Successful implementation of ergonomics programs depend upon effective communication and education of the consumers, and the support, cooperation and collaboration of management and employees.

This case study reviews the knowledge transfer (KT) process of implementing a knife sharpening and steeling program into a poultry processing plant via a participatory ergonomics intervention. This ergonomics intervention required stakeholder participation at the company level to move a 'train-the-trainer' program, developed in Québec, Canada, into action on the plant's deboning line. Communications and exchanges with key stakeholders, as well as changes in steeling and production behaviours were recorded. The intervention was assumed to be at least partially successful because positive changes in work operations occurred. Ergonomic-related changes such as those documented have been cited in the academic literature as beneficial to worker health. However, several components cited in literature that are associated with a successful participatory ergonomics intervention were not attained during the project. A Dynamic Knowledge Transfer Model was used to identify KT issues that impacted on the success of train-the-trainer program. A debriefing analysis reveals that a failure to consider key participatory ergonomics factors necessary for success were related to capacity deficits in the knowledge dissemination strategy.

This study evaluated an ergonomics intervention among Nicaraguan coffee harvesting workers, using electromyography and questionnaire survey techniques. Nicaraguan researchers were involved in the study so that they could gain hands-on experience with ergonomics research and applications, and eventually be the specialists conducting ergonomics interventions in Nicaraguan workplaces. Coffee harvesting activities were studied individually and physical hazards were identified accordingly. The results showed decreased muscle loading on the erector spinae muscle and improved comfort reporting in the back region compared to the commonly used baskets. This fulfils the design objective of a newly developed bag that was used in the intervention to reduce physical workload on the coffee harvesting workers. Workers' opinion survey results showed some issues related to the size of the new bag and the lumbar-shoulder belt mechanism. This information can be used in the modification of the bag in the next design. Key players in the process have been identified. Stimulating ergonomics activities in developing countries is suggested by many experts. This study provided an example from coffee workers in Nicaragua. Commonly used job evaluation procedures and physical load quantification methods were used. Ergonomics researchers and practitioners in developing countries may do similar projects on their own in the future.

Full Text Available Introduction: A high percentage of musculoskeletal disorders in workplaces occur due to awkward posture and non-ergonomic design of the work stations for lifting and carrying of materials. To avoid these injuries, jobs should be designed in a way that ergonomics risk factors are controlled properly. The aim of this study was to utilize ergonomics interventions to minimize ergonomics risk factors in bag packing unit in a mineral processing plant. Material and Method: This cross sectional study was carried out among 20 workers of bag packing unit. Camera recording of working postures, evaluation of medical records, interview, and REBA technique were used to identify the ergonomic risk factors. Interventions included changing the conveyor belt height and the use of spring pallets (spring table. Data were analyzed using Paired T-Test by SPSS software version 18. Result: Before implementing ergonomics intervention, a total of 75% of evaluated postures by REBA technique obtained score of 8-10 (very high risk level and 25% had score of 11-15 (very high risk level that correspond to the action level 3 and 4, respectively. Following the implementation of ergonomics interventions, a total of 90% of the analyzed postures showed action level 2 (moderate risk level and the remainder 10 percent of evaluated postures showed high risk level. Comparison of REBA technique scores before and after implementing interventions showed a significant difference (P-value < 0.05. Conclusion: Based on the findings of this study, the implementation of ergonomics interventions has remarkably decreased the required action level and it may be able to improve work-related postures.

Work-related musculoskeletal disorders (WMSDs) related to computer work have become a serious public health concern. Literature revealed a positive association between computer use and WMSDs. The purpose of this evidence-based pilot project was to provide a series of evidence-based educational sessions on ergonomics to office computer workers to enhance the awareness of risk factors of WMSDs. Seventeen office computer workers who work for the National Board of Certification in Occupational Therapy volunteered for this project. Each participant completed a baseline and post-intervention ergonomics questionnaire and attended six educational sessions. The Rapid Office Strain Assessment and an ergonomics questionnaire were used for data collection. The post-intervention data revealed that 89% of participants were able to identify a greater number of risk factors and answer more questions correctly in knowledge tests of the ergonomics questionnaire. Pre- and post-intervention comparisons showed changes in work posture and behaviors (taking rest breaks, participating in exercise, adjusting workstation) of participants. The findings have implications for injury prevention in office settings and suggest that ergonomics education may yield positive knowledge and behavioral changes among computer workers.

To evaluate surgeon strain using validated ergonomic assessment tools. Observational study (Canadian Task Force classification III). Academic medical center. Robotic surgeons performing gynecologic oncology surgical procedures. Videotape footage of surgeons performing robotic gynecologic oncology procedures was obtained. A human factors engineer experienced with health care ergonomics analyzed the video recordings and performed ergonomic evaluations of the surgeons. An initial evaluation was conducted using the Rapid Upper Limb Assessment (RULA) survey, an ergonomic assessment and prioritization method for determining posture, force, and frequency concerns with focus on the upper limbs. A more detailed analysis followed using the Strain Index (SI) method, which uses multiplicative interactions to identify jobs that are potentially hazardous. Seventeen hours of video recordings were analyzed, and descriptive data based on RULA/SI analysis were collected. Ergonomic evaluation of surgeon activity resulted in a mean RULA score of 6.46 (maximum possible RULA score, 7), indicating a need for further investigation. The mean SI grand score was 24.34. SI scores >10 suggest a potential for hazard to the operator. Thus, the current use of the surgical robot is potentially dangerous with regards to ergonomic positioning and should be modified. At a high-volume robotics center, there are ergonomics deficits that are hazardous to gynecologic surgeons and suggest the need for modification and intervention. A training strategy must be developed to address these ergonomic issues and knowledge deficiencies. Copyright © 2013 AAGL. Published by Elsevier Inc. All rights reserved.

Typing is associated with musculoskeletal disorders (MSDs) caused by multiple risk factors. This control study aimed to evaluate the efficacy of a workplace intervention for reducing MSDs among computer workers. Sixty-six subjects with and without MSD were assigned consecutively to one of three groups: ergonomics intervention (work site and body posture adjustments, muscle activity training and exercises) accompanied with biofeedback training, the same ergonomics intervention without biofeedback and a control group. Evaluation of MSDs, body posture, psychosocial status, upper extremity (UE) kinematics and muscle surface electromyography were carried out before and after the intervention in the workplace and the motion lab. Our main hypothesis that significant differences in the reduction of MSDs will exist between subjects in the study groups and controls was confirmed (χ(2) = 13.3; p = 0.001). Significant changes were found in UE kinematics and posture as well. Both ergonomics interventions effectively reduced MSD and improved body posture. This study aimed to test the efficacy of an individual workplace intervention programme among computer workers by evaluating musculoskeletal disorders (MSDs), body posture, upper extremity kinematics, muscle activity and psychosocial factors were tested. The proposed ergonomics interventions effectively reduced MSDs and improved body posture.

Helali, Faramarz; Lönnroth, Emma-Christin; Shahnavaz, Houshang

2008-01-01

In industrially developing countries, a few ergonomists have directed great efforts towards developing ergonomics awareness among managers and workers in organizations. There is little research on the degree of their success, though. Furthermore, access of organizations to ergonomics knowledge is usually very difficult, especially in industrially developing countries. Thus, building ergonomics awareness is certainly the first phase of the process. Three companies from one industry (44 people: 14 females and 30 males) participated in a project aimed at improving their work system. At the beginning, we needed to create a common goal and ensure participation with appropriate ergonomics tools. The findings of this study were the key issue for the ergonomics intervention (i.e., a shared vision, awakened need of change and learning). Further, to build ergonomics awareness and develop a continuous learning process in the company, it was necessary to use more ergonomics tools through workers' participation in different workplaces.

This paper gives an overview of a participatory ergonomic intervention aimed at reducing low back pain cases in the dispatch department of a catalogue and e-commerce retail company. Based on the findings of the ergonomic analysis and design committee, the company's own employees redesigned the assembly line's layout. As a result of these changes two job tasks that involved manual material handling of boxes, identified by the revised NIOSH equation as posing an increased risk for lifting-related low back pain, were totally eliminated, and the employees responsible for moving boxes from the end of the assembly line to pallets on the ground were given more control over their jobs, and these jobs were also enriched with a new, less heavy task. These results demonstrate that participatory ergonomic interventions are a viable and effective strategy to reduce the exposure to work-related physical and psychosocial risk factors for low back pain.

A participatory ergonomics programme was implemented in an automotive parts manufacturing factory in which an ergonomics change team was formed, composed of members from management, the organized labour union and the research team. It was hypothesized that the participatory nature of this change process would result in enhanced worker perceptions of workplace communication dynamics, decision latitude and influence, which in conjunction with anticipated mechanical exposure reductions would lead to reduced worker pain severity. Utilizing a sister plant in the corporation as a referent group, a quasi-experimental design was employed with a longitudinal, repeat questionnaire approach to document pre-post intervention changes. Nine participatory activities (psychosocial interventions) were implemented as part of the process. Communication dynamics regarding ergonomics were significantly enhanced at the intervention plant compared to the referent plant. However, there were no significantly different changes in worker perceptions of decision latitude or influence between the two plants, nor did pain severity change. Possible explanations for these results include limited intervention intensity, context and co-intervention differences between the two plants, high plant turnover reducing the statistical power of the study and lack of sensitivity and specificity in the psychosocial measures used. Further research should include the development of psychosocial tools more specific to participatory ergonomic interventions and the assessment of the extent of change in psychosocial factors that might be associated with improvements in pain.

Office workers invited and agreeing to participate were assigned to one of three study groups: a group receiving a highly adjustable chair with office ergonomics training, a training-only group, and a control group receiving the training at the end of the study. To examine the effect of office ergonomics intervention in reducing musculoskeletal symptom growth over the workday and, secondarily, pain levels throughout the day. Data collection occurred 2 months and 1 month before the intervention and 2, 6, and 12 months postintervention. During each round, a short daily symptom survey was completed at the beginning, middle, and end of the workday for 5 days during a workweek to measure total bodily pain growth over the workday. Multilevel statistical models were used to test hypotheses. The chair-with-training intervention lowered symptom growth over the workday (P = 0.012) after 12 months of follow-up. No evidence suggested that training alone lowered symptom growth over the workday (P = 0.461); however, average pain levels in both intervention groups were reduced over the workday. Workers who received a highly adjustable chair and office ergonomics training had reduced symptom growth over the workday. The lack of a training-only group effect supports implementing training in conjunction with highly adjustable office furniture and equipment to reduce symptom growth. The ability to reduce symptom growth has implications for understanding how to prevent musculoskeletal injuries in knowledge workers.

The aim of the study was to determine effects of ergonomic intervention on work-related upper extremity musculoskeletal disorders (WUEMSDs) among computer workers. Four hundred computer workers answered a questionnaire on work-related upper extremity musculoskeletal symptoms (WUEMSS). Ninety-four subjects with WUEMSS using computers at least 3 h a day participated in a prospective, randomized controlled 6-month intervention. Body posture and workstation layouts were assessed by the Ergonomic Questionnaire. We used the Visual Analogue Scale to assess the intensity of WUEMSS. The Upper Extremity Function Scale was used to evaluate functional limitations at the neck and upper extremities. Health-related quality of life was assessed with the Short Form-36. After baseline assessment, those in the intervention group participated in a multicomponent ergonomic intervention program including a comprehensive ergonomic training consisting of two interactive sessions, an ergonomic training brochure, and workplace visits with workstation adjustments. Follow-up assessment was conducted after 6 months. In the intervention group, body posture (p 0.05). Ergonomic intervention programs may be effective in reducing ergonomic risk factors among computer workers and consequently in the secondary prevention of WUEMSDs.

A naturally occurring quasi-experimental longitudinal field study of 87 municipal employees using pretest and posttest measures investigated the effects of an office workstation ergonomics intervention program on employees' perceptions of their workstation characteristics, levels of persistent pain, eyestrain, and workstation satisfaction. The study examined whether reactions differed between younger and older employees. Results revealed that workstation improvements were associated with enhanced perceptions of the workstation's ergonomic qualities, less upper back pain, and greater workstation satisfaction. Among those experiencing an improvement, the perceptions of workstation ergonomic qualities increased more for younger than older employees, supporting the "impressionable years" framework in the psychological literature on aging. Implications for human resources managers are discussed.

2003-09-01

Ergonomics analysis of line workers in the electric power industry who work overhead on utility poles revealed some tasks for which less than 1% of the general population had sufficient strength to perform. During a 2-year study, a large Midwestern US electric utility provided a university with a team of represented workers and management. They evaluated, recommended, and monitored interventions for 32 common line worker tasks that were rated at medium to high magnitude of risk factors for musculoskeletal disorders (MSDs). Two of the recommended ergonomic interventions-the battery-operated press and cutter-were selected by the team as having the greatest potential for reducing risk factors of MSDs. Only overhead distribution line worker tasks were evaluated. A business case was formulated that took into account medical injury and illness statistics, workers' compensation, replacement worker and retraining costs. An outline of a business case formulation and a sample intervention payback calculation is shown. Based on the business case, the utility committed over US dollars 300000 to purchase battery-operated presses and cutters for their overhead distribution line crews.

Full Text Available   Background and aims : The present studies show that the theoretical discussions and the applications of ergonomics have not been seriously handled in our country, Iran. So, the aim of the current study was to present an appropriate method which could help in increasing the productivity and decreasing the risk factors of ergonomics in socio-technical systems.   Methods: During the present study, a theoretical model was developed to guide the “ergonomic intervention processes” and its evaluation and application was carried out for an educational organization (EO. The faculty members were selected as the subjects of statistical survey and simple random sampling was performed. The level of musculoskeletal disorders was evaluated in control and treatment groups. Comparative analysis of the obtained data was carried out using fuzzy numbers and their level of confinement.   Results: According to the results of present study with the help of ergonomic interventions, an increase in the activity of staff members, increased revenue, expansion of work with the least number of manpower and a decrease in the overall expenses was seen as compared to the base year. In addition, the analysis of questionnaires with fuzzy approach has shown that the level of musculoskeletal disorders in the experimental group was less as compared to that of control group.   Conclusion: The results obtained by the use of macro and micro ergonomic interventions (Total ergonomics have proved that these methods were successful by increasing the innovation and motivation of the staff members to solve the organizational problems as compared to the base year. The decrease of musculoskeletal disorders among the members resulted to an increase of performance in different units of the educational organization.

The aim of this article is to describe a survey on ergonomic factors of classroom environments of school children, their influence on health, and use of research outcomes to launch a healthy schoolbag initiative. Ergonomics have not yet well penetrated relevant fields in industrially developing countries, such as Sri Lanka. One of the crucial parameters of the school environment is ergonomics. Available evidence suggests ergonomic mismatches in classroom settings. Good practice examples in child ergonomic interventions are few in resource-poor contexts. A school-based cross-sectional study was conducted in a district in Sri Lanka with a sample of 1,607 children in Grades 6 to 8 with the use of a stratified multistage cluster sampling method. Many children did experience discomfort related to substandard seating arrangements in the classroom. A significant proportion had to turn their necks to see the blackboard. For many children, seating locations were not changed. There were widespread incompatibilities of classroom furniture with anthropometric dimensions of children. A majority of children perceived discomfort contributed by mismatched classroom furniture. Carriage of school materials was not healthy. Deficiencies were noted in weight, model, ergonomic features, and carrying behavior of bags. Children experienced several negative effects, in part attributable to mismatched ergonomic factors. The schoolbag was considered a priority issue. Findings were disseminated to stakeholders and to media. Solutions were contemplated on bag weight reduction, healthy schoolbag introduction, and behavior change in a collaborative initiative with the Education Ministry. Political, administrative, and business stakeholders were successfully engaged to inculcate an ergonomic culture in an industrially developing country.

More than 90% of the elementary school students in the world and most of the Iranian students use backpacks. Heavy school bags, failure to apply ergonomics standards in student's backpacks, and also mismatch between anthropometrics dimensions and schoolbag size are important issues for children's health. The purpose of this study was to gather baseline information on the average weight carried by female primary students. It also aimed to evaluate ergonomics standards for student backpacks. A cross-sectional study was conducted on 212 Iranian girl students aged 6- 11 years. Body weight and bag weight were measured with electronic scales and body mass index calculated with WHO software 2007. A questionnaire was constructed to gather information about the backpacks. Body dimensions were measured with VICON motion Analyze system (460). Ergonomics factors were recorded using a checklist. 80.8% of the students used a backpack at a higher weight than recommended by the standards of 10% of body weight. The most common type of schoolbag used was double strap packs (92.5%). The majority of the students carried packs on their backs; however, most of them did not make any adjustments (79.8%). The results have shown a mismatch between the anthropometric measures and the student's backpack dimensions. Parents, students and school staff should be informed about these critical issues as well as suitable controls should be implemented in buying and using the bags.

The application of an industry level participatory ergonomics approach in developing MSD interventions.

Tappin, D C; Vitalis, A; Bentley, T A

2016-01-01

Participatory ergonomics projects are traditionally applied within one organisation. In this study, a participative approach was applied across the New Zealand meat processing industry, involving multiple organisations and geographical regions. The purpose was to develop interventions to reduce musculoskeletal disorder (MSD) risk. This paper considers the value of an industry level participatory ergonomics approach in achieving this. The main rationale for a participative approach included the need for industry credibility, and to generate MSD interventions that address industry level MSD risk factors. An industry key stakeholder group became the primary vehicle for formal participation. The study resulted in an intervention plan that included the wider work system and industry practices. These interventions were championed across the industry by the key stakeholder group and have extended beyond the life of the study. While this approach helped to meet the study aim, the existence of an industry-supported key stakeholder group and a mandate for the initiative are important prerequisites for success.

Turja, Johanna; Kaleva, Simo; Kivistö, Marketta; Seitsamo, Jorma

2012-01-01

The purpose of the controlled longitudinal study was to determine the effect of a tailored early support intervention method on workers' workplace ergonomics. The main areas of the early support intervention were training, guidance and support for supervisors in finding weak signals of impaired ergonomics. Supervisors were also trained to bring up these weak signals in discussion with employees and to make necessary changes at the workplace. The data consisted of 301 intervention subjects and 235 control subjects working in the field of commerce. The questionnaires were carried out in 2008 and in 2010, and the response rates among both groups were 45%. We used multivariate repeated measures analysis of variance (MANOVA) to test the difference in the groups at two points of time. The main result was that in the areas of work environment, the interaction between group and time was statistically significant (p=0.0004). The work environment improved in the intervention group, but deteriorated in the control. Working methods improved due to the interventions, but physical load factors increased over time in both groups. According to the study, tailored early support intervention has a generally beneficial impact on workers' workplace ergonomics in the areas of work methods, work environment and accident factors.

Substantial evidence shows an association between musculoskeletal disorders (MSDs) and certain work-related physical factors. One of the jobs with known ergonomic hazards is working with video display terminals (VDTs). Redesign, ergonomic improvements, and education have generally been recommended as solutions for the prevention of musculoskeletal disorders. We designed this study to assess the effects of ergonomic training on the working postures of VDT users. In an intervention study, we assessed the impact of ergonomic training on the ergonomic hazards and work postures in employees working with VDTs. Participants and their workstations were assessed by Rapid Upper Limb Assessment (RULA) method before and after training. 70 employees of an office, working with a VDT more than four hours per day entered the study. The greatest compliance with OSHA workstation recommendations was seen with the monitor (21.4% of cases) and the least compliance with the one was the chair (10.0%). Mean RULA score before and after intervention were 5.90, and 5.07, respectively, and the difference was statistically significant (p training office ergonomics to the VDT users, even without changing work place components can significantly improve VDT users' behavior and ability to properly fit a workstation to him/herself.

Contradiction analysis: towards a dialectical approach in ergonomics field interventions

Directory of Open Access Journals (Sweden)

Dimitris Nathanael

2015-03-01

Full Text Available The present paper is a methodological contribution to the ergonomics field intervention process. It proposes a perspective on work analysis based on the dialectics notion of contradictions. Contradiction analysis is proposed as being complementary to more established work decomposition methods. The aim of including such an analysis is to frame various heterogeneous determinants of a work activity in practical terms, swiftly and in a manner that preserves its multifaceted unity and essence. Such framing is of particular value when considering alternative design solutions because it provides a practical means for anticipating the effects and side effects of proposed changes. The proposed method is inspired by two theoretical constructs: (i contradiction, as used in Cultural Historical Activity Theory, and (ii regulation, as developed and used by the francophone tradition of the ergonomics of activity. Two brief examples of its use are presented, and its usefulness, possible pitfalls and need for further developments are discussed.

The purpose of this study was to evaluate web-based Knowledge, Attitude and Practice (KAP) intervention on office ergonomics - a unique method for prevention of musculoskeletal discomfort (MSD) - in corporate offices that influences behavior modification. With the increasing use of computers, laptops and hand-held communication devices globally among office employees, creating awareness on office ergonomics has become a top priority. Emphasis needs to be given on maintaining ideal work postures, ergonomic arrangement of workstations, optimizing chair functions, as well as performing desk stretches to reduce MSD arising from the use of these equipment, thereby promoting safe work practices at offices and home, as in the current scenario many employees work from home with flexible work hours. Hence, this justifies the importance of our study. To promote safe working by exploring cost-effective communication methods to achieve behavior change at distant sites when an on-site visit may not be feasible. An invitation was sent by the Medical and Occupational Health Team of a multinational corporation to all employees at their offices in Sri Lanka, Singapore, and Malaysia to take up an online Nordic questionnaire, a screening tool for musculoskeletal symptoms, shared in local languages on two occasions - baseline evaluation ( n = 240) and a follow-up evaluation after 3 months ( n = 203). After completing the baseline questionnaire, employees were immediately trained on correct postures and office ergonomics with animation graphics. The same questionnaire was sent again after a 12-week gap only to those employees who responded to the baseline questionnaire on initial assessment. Data collected were analyzed using the Statistical Package for the Social Sciences (SPSS) version 20.0 software and variables were compared using odds ratio as well as Chi-square test. Of the 203 employees who responded, 47.35% had some musculoskeletal symptoms. Among them 58.7% had lower back pain

Background Improper workstation, work procedures and tools are found to be the risk factors for the development of musculoskeletal disorders among the informal sector workers of the developing countries. Low cost ergonomic interventions can effectively improve such adverse conditions. Case presentation In the present article some studies related to design interventions in different informal and agricultural sectors were discussed and their efficacies were analyzed. It was observed that with the help of appropriate interventions musculoskeletal disorders were reduced, adverse physiological conditions were improved when awkward postures were corrected and ultimately the organisational productivity was increased. Conclusion Proper implementation of ergonomic interventions can ultimately improve the economy of the nation. PMID:25009740

Green ergonomics: definition and scope.

This paper demonstrates that the goals of ergonomics (i.e. effectiveness, efficiency, health, safety and usability) are closely aligned with the goals of design for environmental sustainability. In this paper, the term 'green ergonomics' is conceptualised to specifically describe ergonomics interventions with a pro-nature emphasis. Green ergonomics is focused on the bi-directional connections between human systems and nature. This involves looking at (1) how ergonomics design and evaluation might be used to conserve, preserve, and restore nature and (2) how ecosystem services might be harnessed to facilitate the improved wellbeing and effectiveness of human systems. The paper proposes the scope of green ergonomics based on these bi-directional relationships in the areas of the design of low resource systems and products, the design of green jobs, and the design for behaviour change. Suggestions for further work in the green ergonomics domain are also made. Given the enormous environmental challenges facing modern industrial society, this paper encourages ergonomics science to embrace a pro-nature understanding of work design and research. This paper sets out the role for green ergonomics based on an appreciation of the human-nature connections that have been integrated with our understanding of ergonomics science and practice.

This study explored factors contributing to intervention adoption decisions among Emergency Medical Service (EMS) workers. Emergency Medical Service workers (n = 190), from six different organisations, participated in a two-month longitudinal study following the introduction of a patient transfer-board (also known as slide-board) designed to ease lateral transfers of patients to and from ambulance cots. Surveys administered at baseline, after one month and after two months sampled factors potentially influencing the EMS providers' decision process. 'Ergonomics Advantage' and 'Patient Advantage' entered into a stepwise regression model predicting 'intention to use' at the end of month one (R (2 )= 0.78). After the second month, the stepwise regression indicated only two factors were predictive of intention to use: 'Ergonomics Advantage,' and 'Endorsed by Champions' (R (2 )= 0.58). Actual use was predicted by: 'Ergonomics Advantage' and 'Previous Tool Experience.' These results relate to key concepts identified in the diffusion of innovation literature and have the potential to further ergonomics intervention adoption efforts. Practitioner Summary. This study explored factors that potentially facilitate the adoption of voluntarily used ergonomics interventions. EMS workers were provided with foldable transfer-boards (slideboards) designed to reduce the physical demands when laterally transferring patients. Factors predictive of adoption measures included perceived ergonomics advantage, the endorsement by champions, and prior tool experience.

This paper aims at the application of an ergonomic maturity model (EMM), in order to assess the ergonomic sustainability outreach of ergonomic actions. This proposition was motivated by the widespread sensation that the development of the discipline, its educational devices and related practices depends on the attitude of ergonomics practitioners rather than environmental macroergonomic conditions. Maturity modeling in this paper is undertaken as a tool for ergonomic practitioners. Thus, its foundations were uprooted from diverse fields: Clinic Psychology, Quality Management and Project Management. The paper brings about a detailled explanation of this ergonomic maturity tool. The empirical part is fulfilled by the examination - using the EMM - of four emblematic cases excerpted from our research lab ergonomic portfolio.

Musculoskeletal strain and other symptoms are common in visual display unit (VDU) work. Psychosocial factors are closely related to the outcome and experience of musculoskeletal strain. The user-computer relationship from the viewpoint of the quality of perceived competence in computer use was assessed as a psychosocial stress indicator. It was assumed that the perceived competence in computer use moderates the experience of musculoskeletal strain and the success of the ergonomics intervention. The participants (n = 124, female 58%, male 42%) worked with VDU for more than 4 h per week. They took part in an ergonomics intervention and were allocated into three groups: intensive; education; and reference group. Musculoskeletal strain, the level of ergonomics of the workstation assessed by the experts in ergonomics and amount of VDU work were estimated at the baseline and at the 10-month follow-up. Age, gender and the perceived competence in computer use were assessed at the baseline. The perceived competence in computer use predicted strain in the upper and the lower part of the body at the follow-up. The interaction effect shows that the intensive ergonomics intervention procedure was the most effective among participants with high perceived competence. The interpretation of the results was that an anxiety-provoking and stressful user-computer relationship prevented the participants from being motivated and from learning in the ergonomics intervention. In the intervention it is important to increase the computer competence along with the improvements of physical workstation and work organization.

More than seven out of 10 Dutch construction workers describe their work as physically demanding. Ergonomic measures can be used to reduce these physically demanding work tasks. To increase the use of ergonomic measures, employers and workers have to get used to other working methods and to maintaining them. To facilitate this behavioural change, participatory ergonomics (PE) interventions could be useful. For this study a protocol of a PE intervention is adapted in such a way that the intervention can be performed by an ergonomics consultant through face-to-face contacts or email contacts. The objective of this study is to evaluate the effectiveness of the face-to-face guidance strategy and the e-guidance strategy on the primary outcome measure: use of ergonomic measures by individual construction workers, and on the secondary outcome measures: the work ability, physical functioning and limitations due to physical problems of individual workers. The present study is a randomised intervention trial of six months in 12 companies to establish the effects of a PE intervention guided by four face-to-face contacts (N = 6) or guided by 13 email contacts (N = 6) on the primary and secondary outcome measures at baseline and after six months. Construction companies are randomly assigned to one of the guidance strategies with the help of a computer generated randomisation table. In addition, a process evaluation for both strategies will be performed to determine reach, dose delivered, dose received, precision, competence, satisfaction and behavioural change to find possible barriers and facilitators for both strategies. A cost-benefit analysis will be performed to establish the financial consequences of both strategies. The present study is in accordance with the CONSORT statement. The outcome of this study will help to 1) evaluate the effect of both guidance strategies, and 2) find barriers to and facilitators of both guidance strategies. When these strategies are

This research deals with the influence of the computer use in schools related to the children posture, in an ergonomic point of view. The research tries to identify probable causes for the children early postural constraints, relating it to the sedentary behavior and the lack of an ergonomic project in schools. The survey involved 186 children, between 8 and 12 years old, students of a private school in Rio de Janeiro-Brasil. An historical and theoretical school furniture research was conducted as well as a survey with the students and teachers, computer postural evaluation, ergonomic evaluation (RULA method), and observations in the computer classroom. The research dealt with the student's perception with respect to the furniture utilized by him in the classroom during the use of the computer, his body complaint, the time he spent working on the school computer and the possibility of the existence of sedentariness. Also deals with the teachers' perception and knowledge regarding ergonomics with reference to schoolroom furniture and its Regulatory Norms (RN). The purpose of the research work is to highlight the importance of this knowledge, having in view the possibility of the teachers' collaboration in the ergonomic adaptation of the classroom environment and in their conscientious opinion during the purchasing of this furniture. A questionnaire was utilized and its results showed some discontent on the part of the teachers with relation to the schoolroom furniture as well as the teachers' scant knowledge of Ergonomics.We conclude with a survey that despite the children had constraints in postural assessments and school furniture needs a major ergonomic action, the time that children use the computer at school is small compared with the time of use at home and therefore insufficient to be the main cause of quantified commitments, thus the study of computer use at home as a development and continuity of this research.

Full Text Available The aims of this study were to investigate work related and individual factors as predictors of insident neck pain among video display unit (VDU workers, to assess the effects of an ergonomic intervention and education on musculoskeletal symptoms, and to study the repeatability and validity of an expert assessment method of VDU workstation ergonomics. A method to assess the risk factors for upper limb disorders was developed, and its validity and repeatability were studied. The annual incidence of neck pain was 34.4%. A poor physical work environment and placement of the keyboard were work-related factors increasing the risk of neck pain. Among the individual factors, female sex was a strong predictor. The randomized intervention study included questionnaire survey, a diary of discomfort, and ergonomic rating of the workstations. The subjects (n=124 were allocated into three groups. The intensive and the education groups had less musculoskeletal discomfort than the control group at the 2-month follow-up. After the intervention, the level of ergonomics was distinctly higher in the intensive ergonomic group than in the education or control group. Two experts in ergonomics analyzed and rated the ergonomics of workstations before and after intervention. The validity of the assessment method was rated against the technical measurements, assessment of tidiness and space, and work chair ergonomics. The intraclass correlation coefficient between ratings of the two experts was 0.74. Changes in the location of the input devises and the screen, as well as the values of tidiness and space and work chair ergonomics showed a significant association with the ratings of both experts. The method to assess the loads imposed on the upper limbs was validated against the expert observations from the video, continuous recordings of myoelectric activity of forearm muscles, and wrist posture, measured with goniometers. Inter-observer repeatability and validity were

To examine the efficacy of a participatory ergonomics intervention in preventing musculoskeletal disorders among kitchen workers. Participatory ergonomics is commonly recommended to reduce musculoskeletal disorders, but evidence for its effectiveness is sparse. A cluster randomised controlled trial among the 504 workers of 119 kitchens in Finland was conducted during 2002-2005. Kitchens were randomised to an intervention (n = 59) and control (n = 60) group. The duration of the intervention that guided the workers to identify strenuous work tasks and to seek solutions for decreasing physical and mental workload, was 11 to 14 months. In total, 402 ergonomic changes were implemented. The main outcome measures were the occurrence of and trouble caused by musculoskeletal pain in seven anatomical sites, local fatigue after work, and sick leave due to musculoskeletal disorders. Individual level data were collected by a questionnaire at baseline and every 3 months during the intervention and 1-year follow-up period. All response rates exceeded 92%. No systematic differences in any outcome variable were found between the intervention and control groups during the intervention or during the 1-year follow-up. The intervention did not reduce perceived physical work load and no evidence was found for the efficacy of the intervention in preventing musculoskeletal disorders among kitchen workers. It may be that a more comprehensive redesign of work organisation and processes is needed, taking more account of workers' physical and mental resources.

Visual requirements are high when sorting mail. The purpose of this visual ergonomics intervention study was to evaluate the visual environment in mail sorting facilities and to explore opportunities for improving the work situation by reducing visual strain, improving the visual work environment and reducing mail sorting time. Twenty-seven postmen/women participated in a pre-intervention study, which included questionnaires on their experiences of light, visual ergonomics, health, and musculoskeletal symptoms. Measurements of lighting conditions and productivity were also performed along with eye examinations of the postmen/women. The results from the pre-intervention study showed that the postmen/women who suffered from eyestrain had a higher prevalence of musculoskeletal disorders (MSD) and sorted slower, than those without eyestrain. Illuminance and illuminance uniformity improved as a result of the intervention. The two post-intervention follow-ups showed a higher prevalence of MSD among the postmen/women with eyestrain than among those without. The previous differences in sorting time for employees with and without eyestrain disappeared. After the intervention, the postmen/women felt better in general, experienced less work induced stress, and considered that the total general lighting had improved. The most pronounced decreases in eyestrain, MSD, and mail sorting time were seen among the younger participants of the group. Copyright © 2011 Elsevier Ltd and The Ergonomics Society.

The issue of childhood overweight and obesity has become a global public health crisis. School-based interventions have been developed and implemented to combat this growing concern. The purpose of this review is to compare and contrast U.S. and international school-based obesity prevention interventions and highlight efficacious strategies. A systematic literature review was conducted utilizing five relevant databases. Inclusion criteria were: (1) primary research; (2) overweight or obesity prevention interventions; (3) school-based; (4) studies published between 1 January 2002 through 31 December 2013; (5) published in the English language; (6) child-based interventions, which could include parents; and (7) studies that reported outcome data. A total of 20 interventions met the inclusion criteria. Ten interventions each were implemented in the U.S. and internationally. International interventions only targeted elementary-aged students, were less likely to target low-income populations, and were less likely to be implemented for two or more years in duration. However, they were more likely to integrate an environmental component when compared to U.S. interventions. Interventions implemented in the U.S. and internationally resulted in successful outcomes, including positive changes in student BMI. Yet, varying approaches were used to achieve success, reinforcing the fact that a one-size-fits-all approach is not necessary to impact childhood obesity. However, building on successful interventions, future school-based obesity prevention interventions should integrate culturally specific intervention strategies, aim to incorporate an environmental component, and include parents whenever possible. Consideration should be given to the potential impact of long-term, frequent dosage interventions, and subsequent follow-up should be given attention to determine long-term efficacy.

A large-scale field intervention study was undertaken to examine the effects of office ergonomics training coupled with a highly adjustable chair on office workers' knowledge and musculoskeletal risks. Office workers were assigned to one of three study groups: a group receiving the training and adjustable chair (n=96), a training-only group (n=63), and a control group (n=57). The office ergonomics training program was created using an instructional systems design model. A pre/post-training knowledge test was administered to all those who attended the training. Body postures and workstation set-ups were observed before and after the intervention. Perceived control over the physical work environment was higher for both intervention groups as compared to workers in the control group. A significant increase in overall ergonomic knowledge was observed for the intervention groups. Both intervention groups exhibited higher level behavioral translation and had lower musculoskeletal risk than the control group.

Background Work-related musculoskeletal disorders (WMSD) among construction workers remain high. Participatory ergonomics (PE) interventions that engage workers and employers in reducing work injury risks have shown mixed results. Methods Eight-six workers from seven contractors participated in a PE program. A logic model guided the process evaluation and summative evaluation of short term and intermediate impacts and long term outcomes from surveys and field records. Results Process measures showed good delivery of training, high worker engagement, and low contractor participation. Workers’ knowledge improved and workers reported changes to work practices and tools used; contractor provision of appropriate equipment was low (33%). No changes were seen in symptoms or reported physical effort. Conclusions The PE program produced many worker-identified ergonomic solutions, but lacked needed support from contractors. Future interventions should engage higher levels of the construction organizational system to improve contractor involvement for reducing WMSD. PMID:27094450

Full Text Available Taylor's University School of Engineering (Malaysia is a project-based-learning school that puts a conscious effort to educate engineers on the importance of applying ergonomic principles at the conceiving and designing stages of a product life cycle. This paper reports on an innovative approach to teaching ergonomics using the SUCCESS framework (Simple, Unexpected, Credible, Concrete, Emotions, Story, and Simulation. This teaching technique was adopted to engage the hearts and minds of the students and get them to embrace ergonomics as an important skill for engineers. Comparing students’ module evaluation and feedback, both before and after the adoption of the SUCCESS framework showed that students enjoyed the new approach of teaching and found it more fulfilling.

Ergonomic intervention: its effect on working posture and musculoskeletal symptoms in female biomedical scientists.

LENUS (Irish Health Repository)

Kilroy, N

2000-01-01

This study investigates the effect of ergonomic intervention on working posture and musculoskeletal symptoms in female biomedical scientists. The Nordic musculoskeletal questionnaire (NMQ), body discomfort chart (BDC) and rapid upper-limb assessment (RULA) are the tools for assessment. The study was conducted in three phases: pre-intervention, intervention and post-intervention. Pre-intervention, 79% of subjects reported a three-month prevalence of symptoms, and these were reported more frequently by those working in haematology\\/transfusion. Analysis by RULA showed that the majority (59%) of postures had a grand score of four. A further 24% had scores of five or six. The highest frequency of poor postures was seen in haematology\\/transfusion. Intervention comprised physical workplace changes, a seminar, and advice on risk factors. In the post-intervention phase, baseline measurements were repeated. Reporting of three-month prevalence of symptoms had decreased to 54%, and reports of body discomfort also had decreased. The majority (64%) had a RULA grand score of three. No observed postures had scores of five or six. In conclusion, ergonomic intervention resulted in an improvement in working postures, and a decrease in the prevalence of musculoskeletal symptoms and body discomfort. Analysis of findings indicate that RULA scores generally corresponded with reporting of symptoms (NMQ) and discomfort (BDC).

To study the effect of a participatory ergonomics intervention on psychosocial factors among kitchen workers. A cluster randomised controlled trial. Four cities in Finland, 2002-2005. 504 workers in 119 municipal kitchens. Kitchens were randomised to intervention (n=59) and control (n=60) groups. The intervention lasted 11-14 months and was based on the workers' active participation in work analysis, planning and implementing the ergonomic changes aimed at decreasing the physical and mental workload. Mental stress, mental strenuousness of work, hurry, job satisfaction, job control, skill discretion, co-worker relationships and supervisor support. Data were collected by questionnaire at baseline, at the end of the intervention, and at a 12-month follow-up (PI(12)). At the end of the intervention, the OR of job dissatisfaction for the intervention group as compared with the control group was 3.0 (95% CI 1.1 to 8.5), of mental stress 2.3 (1.2 to 4.7) and of poor co-worker relationships 2.3 (1.0 to 5.2). At the PI(12), the OR of job dissatisfaction was 3.0 (1.2 to 7.8). Analysis of the independent and joint effects of the intervention and unconnected organisational reforms showed that adverse changes were accentuated among those with exposure to both. No favourable effects on psychosocial factors at work were found. The adverse changes were due to a joint effect of the intervention and the unconnected organisational reforms. The findings do not support the usefulness of this kind of intervention in changing unsatisfactory psychosocial working conditions.

Does proactive ergonomics program enhance office worker health and productivity? The investigation was conducted in connection with the move of 1500 office staff to a building with improved ergonomics. It was focused on associations between workstation features, working postures, musculoskeletal pain symptoms, and eye strain before and 18 months after implementation of a proactive ergonomic program. The outcomes were compared between the intervention and a similar reference group. Associations between improvement of postures and less musculoskeletal pain and eye strain were confirmed. A cross association between several features and postures and improved symptoms was noted, along with improved productivity. The study suggests that a proactive program adhering to the OSHA recommendations needs to include an individual workstation assessment to be effective in reducing symptoms and increasing productivity.

Introduction of notebook computers in many schools has become integral to learning. This has increased students' screen-based exposure and the potential risks to physical and visual health. Unhealthy computing behaviours include frequent and long durations of exposure; awkward postures due to inappropriate furniture and workstation layout, and ignoring computer-related discomfort. Describe the framework for a planned school-based health promotion program to encourage healthy computing behaviours among middle school students. This planned program uses a community- based participatory research approach. Students in Year 7 in 2011 at a co-educational middle school, their parents, and teachers have been recruited. Baseline data was collected on students' knowledge of computer ergonomics, current notebook exposure, and attitudes towards healthy computing behaviours; and teachers' and self-perceived competence to promote healthy notebook use among students, and what education they wanted. The health promotion program is being developed by an inter-professional team in collaboration with students, teachers and parents to embed concepts of ergonomics education in relevant school activities and school culture. End of year changes in reported and observed student computing behaviours will be used to determine the effectiveness of the program. Building a body of evidence regarding physical health benefits to students from this school-based ergonomics program can guide policy development on the healthy use of computers within children's educational environments.

ENGLISH ABSTRACT: To develop high quality products, a designer has to consider various influential factors, one of which is ergonomics. And to fashion a specific product for the user, a designer needs expert knowledge of the user’s requirements. However, expert knowledge can also be accessed through an intelligent advisory system for ergonomic design support. The effectiveness of such an expert system depends mainly on the quality of the knowledge base and on the appropriateness of the system's inference engine. Data for the system’s knowledge base can be collected in different ways. One approach is to study relevant projects to collect appropriate ergonomic solutions; another is to recognise bottlenecks in ergonomic design. This paper presents a case study of the design of an actual chainsaw – with emphasis on ergonomic design solutions – that can be transformed into ergonomic design recommendations. At the end of the paper, an application of one of the derived recommendations within the knowledge base of the intelligent advisory system is presented.

School-Based Gay-Affirmative Interventions: First Amendment and Ethical Concerns

Science.gov (United States)

Bayer, Ronald

2013-01-01

Public health professionals and educators have developed effective school-based interventions to reduce prejudice and stigma against lesbian, gay, bisexual, and transgender (LGBT) students. Such interventions can reduce the harm caused to sexual minority youths by stigma and can improve health outcomes. However, critics have warned that these interventions attempt to control speech and religious beliefs protected by the First Amendment. We review this critique and assess the legal and ethical arguments. We conclude that, both legally and ethically, there is great leeway for schools to implement LGBT-affirmative interventions. Still, we recommend that interventionists attend critics’ concerns using principles of community-based participatory research (CBPR). Using CBPR approaches, interventionists can achieve better community acceptance and cooperation and more successful interventions. PMID:23948002

Childhood obesity has become a major public health issue today. The prevalence of obesity and overweight is increasing in both adults and children. Childhood obesity in Thailand has more than doubled since the 1960s and a recent study reported that overweight and obesity in Thais is the 5th highest in Asia. The present study objective was to evaluate the effectiveness of a life-skills, multicomponent, school-based intervention on child nutritional status. A quasi-experimental design was conducted in two-groups (control and intervention schools) on 453 students attending grade levels 4-5 in Bangkok. Two schools were selected for control, and two schools for intervention groups. The interventions included education, diet, physical activity (PA), food-environment, school builtenvironment, and life-skills components. Subjects were measured at baseline and at 6 months post-treatment. The intervention group had significant differences in overall healthy practices (+1.5 mean difference, p=0.048), dietary habits, physical activity, lower total cholesterol (TC) levels (-2.43 mean, p=0.019) and higher high density lipoprotein cholesterol (HDL-C) levels (+4.06 p=0.028) as compared to the control. A higher reduction of overweight individuals among the intervention group over the intervention period was observed. Physical activity and consumption of vegetables increased while consumption of high-caloric snacks and fast foods decreased in children after the intervention. This study indicated that a multidisciplinary approach in school-based interventions is most likely to be effective in preventing children from becoming overweight in the long term. More research should be conducted on school-based interventions with longer intervention periods and higher sustainability.

Ergonomics risk factors apply to everybody. Numerous adults have experienced disabling injuries related to use of computers and other forms of technology. Now children are using technology even more than adults. Increasingly ergonomics risk factors are being recognized as present in the world of children. Outreach to schools and the surrounding community by employers may help protect the future work force. A growing body of researchers believe that children can benefit from the early introduction of ergonomics awareness and preventative measures. While individual representatives of the educational system may embrace the concept of introducing ergonomics into the classroom, a number of barriers can prevent implementation of integrated programs. Some of the barriers to introducing ergonomics in schools have been absence of a tie to educational standards, the existing demands on teaching hours, and the absence of easily executable lesson plans. Ergonomics is rarely included in teacher training and professional ergonomics expertise is needed for the development of a class-based program. As part of Strategic Vision plan for 2025, a National Laboratory identified community outreach and the future workforces as key areas for initiatives. A series of hands-on interactive modules have been developed by professional ergonomics specialists. They are being tested with elementary, middle and high school students. Where possible, the content has been tied to the educational standards in the State of California in the USA. Currently the modules include grip strength, effective breathing, optimal keyboard and mouse positions, optimizing chairs, posture and movement, backpack safety and safe lifting. Each module takes the students through a related activity or experience. An individual worksheet asks them questions about the experience and guides them to consider implications in their activities of daily living. A module on hearing is under development. The goal is to have a

A macroergonomics intervention consisting of flexible workspace design and ergonomics training was conducted to examine the effects on psychosocial work environment, musculoskeletal health, and work effectiveness in a computer-based office setting. Knowledge workers were assigned to one of four conditions: flexible workspace (n=121), ergonomics training (n=92), flexible workspace+ergonomics training (n=31), and a no-intervention control (n=45). Outcome measures were collected 2 months prior to the intervention and 3 and 6 months post-intervention. Overall, the study results indicated positive, significant effects on the outcome variables for the two intervention groups compared to the control group, including work-related musculoskeletal discomfort, job control, environmental satisfaction, sense of community, ergonomic climate, communication and collaboration, and business process efficiency (time and costs). However, attrition of workers in the ergonomics training condition precluded an evaluation of the effects of this intervention. This study suggests that a macroergonomics intervention is effective among knowledge workers in office settings.

Full Text Available Abstract Background Active commuting to school has declined over time, and interventions are needed to reverse this trend. The main objective was to investigate the effects of a school-based intervention on active commuting to school and health-related fitness in school-age children of Southern Spain. Methods A total of 494 children aged 8 to 11 years were invited to participate in the study. The schools were non-randomly allocated (i.e., school level allocation into the experimental group (EG or the control group (CG. The EG received an intervention program for 6 months (a monthly activity focused on increasing the level of active commuting to school and mainly targeting children’s perceptions and attitudes. Active commuting to school and health-related fitness (i.e., cardiorespiratory fitness, muscular fitness and speed-agility, were measured at baseline and at the end of the intervention. Children with valid data on commuting to school at baseline and follow-up, sex, age and distance from home to school were included in the final analysis (n = 251. Data was analyzed through a factorial ANOVA and the Bonferroni post-hoc test. Results At follow up, the EG had higher rates of cycling to school than CG for boys only (p = 0.04, but not for walking to school for boys or girls. The EG avoided increases in the rates of passive commuting at follow up, which increased in the CG among girls for car (MD = 1.77; SE = 0.714; p = 0.010 and bus (MD = 1.77; SE = 0.714; p = 0.010 modes. Moreover, we observed significant interactions and main effects between independent variables (study group, sex and assessment time point on health-related fitness (p < 0.05 over the 6-month period between groups, with higher values in the control group (mainly in boys. Conclusion A school-based intervention focused on increasing active commuting to school was associated with increases in rates of cycling to school among boys, but not for

One particular focus of refugee studies in the United States has been the violence experience of Southeast Asian (S.E.A.) refugee children and its impact on mental health and school adaptation. Although virtually all researchers have found that the children have high rates of depression and/or post-traumatic stress disorder, findings concerning successful school adaptation have been inconclusive. Even so, concern has been generated on how to best meet the children's mental health needs. The purpose of our study was to provide an eight-week school-based program that was designed to reduce depression symptoms of S.E.A. refugee children. Specifically, this collaborative program addressed refugee adaptation issues, children's culture and the development of coping skills. All of the children were screened for depression using the Children's Depression Inventory (CDI). Analysis of CDI data revealed that children's depression scores had a significant decrease between screening times 1 (approximately one month before the intervention) and 2 (fourth week of the intervention), 1 and 3 (eighth week of the intervention) and 1 and 4 (one month following the intervention). Globally, culturally sensitive mental health school-based programs may be an appropriate intervention to assist immigrant and refugee children in making a successful adaptation to host countries.

Small-Medium sized (SME) is a focal type of Indonesian industry which contributes to national emerging economies. Indonesian goverment has developed employee social security system (BPJS Ketenagakerjaan) to support worker quality of life. However, there were limited research which could assist BPJS Ketenagakerjaan in evaluating worker quality of life. Worker quality of life could be categorized as the highest worker needs or affective states. SME Worker Affective (SWA) index is being concerned as a basic tool to make balance between worker performance and quality of life in workstation of SMEs. The research objectives are: 1) To optimize the environmental ergonomics in SMEs; 2) To quantify SME Worker Affective (SWA) index based on optimized environmental ergonomics. The research advantage is to support Indonesian goverment in monitoring SMEs good practices to its worker quality of life. Simulated annealing optimized the heart rate and environmental ergonomics parameters. SWA index was determined based on comparison between optimized heart rate and environmental ergonomics parameters. SWA index were quantified for 380 data of worker. The evaluation indicated 51.3% worker in affective and 48.7% in non-affective condition. Research results indicated that stakeholders of SMEs should put more attention on environmental ergonomics and worker affective.

Childhood obesity has become a major public health issue today. The prevalence of obesity and overweight is increasing in both adult and children. Childhood obesity in Thailand has more than doubled since the 1960s and a recent study reported that overweight and obesity in Thai is the 5th highest in Asia. The present study objective is to evaluate the effectiveness of a life skills multicomponent school-based intervention on children's nutritional status. Methods: A quasi-experimental design was conducted in two-groups (control and intervention schools) on 453 students attending grade levels 4-5 in Bangkok. Two schools were selected for control, and two schools for intervention groups. The intervention included education, dietary, physical activity, food-environment, school built-environment, and life skills components. Outcomes were measured at baseline and post-treatment measured after 6 months. Results: The intervention group had significant improvements in healthier practice (+1.5 mean difference, p=0.048) on dietary habits and physical activity, lowered cholesterol levels (-2.43 mean, p=0.019), and higher HDL levels (+4.06 p=0.028) as compared to control. A higher reduction of overweight individuals among the intervention group over the intervention period was observed. Physical activity and consumption of vegetable increased while consumption of high-caloric snacks and fasts food decreased in children after the intervention. Conclusion: Childhood overweight and obesity is a serious public health problem based on its increasing rates and the associated health risks. This study indicated that multidisciplinary approach on school-based interventions is likely most effective to prevent children becoming overweight in long term. More research should be conducted on school-based intervention with longer intervention periods with higher sustainability. (author)

Implementation science is an emerging area in physical activity (PA) research. We sought to establish the current state of the evidence related to implementation of school-based PA models to explore 1) the relationship between implementation and health outcomes, and 2) factors that influence implementation. We searched 7 electronic databases (1995-2014) and included controlled studies of school-based PA programmes for healthy youth (6-18 y) measuring at least one physical health-related outcome. For objective 1, studies linked implementation level to student-level health outcome(s). For objective 2, studies reported factors associated with implementation. There was substantial variability in how health outcomes and implementation were assessed. Few studies linked implementation and health outcomes (n=15 interventions). Most (11/15) reported a positive relationship between implementation and at least one health outcome. Implementation factors were reported in 29 interventions. Of 22 unique categories, time was the most prevalent influencing factor followed by resource availability/quality and supportive school climate. Implementation evaluation supports scale-up of effective school-based PA interventions and thus population-level change. Our review serves as a call to action to 1) address the link between implementation and outcome within the school-based PA literature and 2) improve and standardize definitions and measurement of implementation.

This study aimed to determine the effects of participatory workplace improvement (PWI) -based provision of ergonomic training and ergonomic action checklists (ACLs) to on-site managers on workplace improvement activities for low back pain (LBP). A randomized controlled trial (RCT) was conducted at a manufacturing company in Japan. Teams entered in the study were randomly assigned to a control and an intervention group. A total of three interventional training sessions on methods of ergonomics were provided to on-site managers in the intervention group, with 1-month intervals between sessions. Ergonomic ACLs were provided at the same time. After completion of the training sessions, each team then provided a report of improvements each month for the next 10 months. Two people in charge of safety and health chose two major objectives of the implemented activities from the five categories. The reported number of improvements was analyzed using a Poisson regression model. In the intervention group, although the incident rate ratio (IRR) of PWIs in countermeasures for the LBP category was significantly elevated after the training sessions, the IRR of improvements decreased over time during the 10-month follow-up period. No significant difference was observed in the IRR of total PWIs in either the control or intervention group. PWI-based provision of ergonomic training sessions and ergonomics ACLs to on-site managers was shown to be effective for workplace improvement activities targeted at LBP. However, because the effects decrease over time, efforts should be made to maintain the effects through regular interventions.

Objectives: This study aimed to determine the effects of participatory workplace improvement (PWI) -based provision of ergonomic training and ergonomic action checklists (ACLs) to on-site managers on workplace improvement activities for low back pain (LBP). Methods: A randomized controlled trial (RCT) was conducted at a manufacturing company in Japan. Teams entered in the study were randomly assigned to a control and an intervention group. A total of three interventional training sessions on methods of ergonomics were provided to on-site managers in the intervention group, with 1-month intervals between sessions. Ergonomic ACLs were provided at the same time. After completion of the training sessions, each team then provided a report of improvements each month for the next 10 months. Two people in charge of safety and health chose two major objectives of the implemented activities from the five categories. The reported number of improvements was analyzed using a Poisson regression model. Results: In the intervention group, although the incident rate ratio (IRR) of PWIs in countermeasures for the LBP category was significantly elevated after the training sessions, the IRR of improvements decreased over time during the 10-month follow-up period. No significant difference was observed in the IRR of total PWIs in either the control or intervention group. Conclusions: PWI-based provision of ergonomic training sessions and ergonomics ACLs to on-site managers was shown to be effective for workplace improvement activities targeted at LBP. However, because the effects decrease over time, efforts should be made to maintain the effects through regular interventions. PMID:28320978

Strategy for finding the appropriate strategy for work tool development has become a crucial issue in occupational wellness of varied nature of women workforce of Northeast India. This paper deals with ergonomics intervention through sustainable work tool design development process. Workers who frequently shift to different activities quite often in unorganised small-scale fruit processing units where productivity is directly related to the harvesting season require different work tools relevant to specific tasks and mostly workers themselves manage work tools of their own with available local resources. Whereas in contrast the tea-leaf pluckers are engaged in a single task throughout the year, and the work schedule and work equipment is decided and supplied to them based on the corporate decision where the workers do not have any individual control. Observations confirm the need for organising participatory workshops specific to trade based occupational well-being and different work tools for different tasks in mostly private owned unorganised sector. Implementation of single variety work tool development that supports a crucial component in tea-leaf plucking for which they are engaged in full time employment; and through a corporate decision a single design with its number of users makes a good effect.

Non-surgical treatment, including ergonomic positioning or equipment, are sometimes offered to people experiencing mild to moderate symptoms from carpal tunnel syndrome (CTS). The effectiveness and duration of benefit from ergonomic positioning or equipment interventions for treating CTS are unknown. To assess the effects of ergonomic positioning or equipment compared with no treatment, a placebo or another non-surgical intervention in people with CTS. We searched the Cochrane Neuromuscular Disease Group Specialized Register (14 June 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (2011, Issue 2, in The Cochrane Library), MEDLINE (1966 to June 2011), EMBASE (1980 to June 2011), CINAHL Plus (1937 to June 2011), and AMED (1985 to June 2011). We also reviewed the reference lists of randomised or quasi-randomised trials identified from the electronic search. Randomised or quasi-randomised controlled trials comparing ergonomic positioning or equipment with no treatment, placebo or another non-surgical intervention in people with CTS. Two review authors independently selected trials for inclusion, extracted data and assessed risk of bias of included studies. We calculated risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CI) for the primary and secondary outcomes. We pooled results of clinically and statistically homogeneous trials, where possible, to provide estimates of the effect of ergonomic positioning or equipment. We included two trials (105 participants) comparing ergonomic versus placebo keyboards. Neither trial assessed the primary outcome (short-term overall improvement) or adverse effects of interventions. In one small trial (25 participants) an ergonomic keyboard significantly reduced pain after 12 weeks (MD -2.40; 95% CI -4.45 to -0.35) but not six weeks (MD -0.20; 95% CI -1.51 to 1.11). In this same study, there was no difference between ergonomic and standard keyboards in hand function at six or 12 weeks or palm

Training in robot-assisted surgery focusses mainly on technical skills and instrument use. Training in optimal ergonomics during robotic surgery is often lacking, while improved ergonomics can be one of the key advantages of robot-assisted surgery. Therefore, the aim of this study was to assess whether a brief explanation on ergonomics of the console can improve body posture and performance. A comparative study was performed with 26 surgical interns and residents using the da Vinci skills simulator (Intuitive Surgical, Sunnyvale, CA). The intervention group received a compact instruction on ergonomic settings and coaching on clutch usage, while the control group received standard instructions for usage of the system. Participants performed two sets of five exercises. Analysis was performed on ergonomic score (RULA) and performance scores provided by the simulator. Mental and physical load scores (NASA-TLX and LED score) were also registered. The intervention group performed better in the clutch-oriented exercises, displaying less unnecessary movement and smaller deviation from the neutral position of the hands. The intervention group also scored significantly better on the RULA ergonomic score in both the exercises. No differences in overall performance scores and subjective scores were detected. The benefits of a brief instruction on ergonomics for novices are clear in this study. A single session of coaching and instruction leads to better ergonomic scores. The control group showed often inadequate ergonomic scores. No significant differences were found regarding physical discomfort, mental task load and overall performance scores.

The importance of careful theory-based intervention planning is recognized for fruit and vegetable promotion. This paper describes the application of the Intervention Mapping (IM) protocol to develop the Pro Children intervention to promote consumption of fruit and vegetable among 10- to 13-year-old schoolchildren. Based on a needs assessment, promotion of intake of fruit and vegetable was split into performance objectives and related personal, social and environmental determinants. Crossing the performance objectives with related important and changeable determinants resulted in a matrix of learning and change objectives for which appropriate educational strategies were identified. Theoretically similar but culturally relevant interventions were designed, implemented and evaluated in Norway, the Netherlands and Spain during 2 school years. Programme activities included provision of fruits and vegetables in the schools, guided classroom activities, computer-tailored feedback and advice for children, and activities to be completed at home with the family. Additionally, optional intervention components for community reinforcement included incorporation of mass media, school health services or grocery stores. School project committees were supported. The Pro Children intervention was carefully developed based on the IM protocol that resulted in a comprehensive school-based fruit and vegetable promotion programme, but culturally sensible and locally relevant.

Peter K. Smith

2016-10-01

Full Text Available Following some background studies on the nature of school bullying, its prevalence, and the negative consequences it can have, this article reviews the history of anti-bullying interventions over the last 30 years. It considers several major programmes in detail, such as the Olweus Bullying Prevention Program, KiVa, Steps to Respect, and Friendly Schools. The nature and evaluation of the interventions is discussed, followed by a review of meta-analyses of the programmes effectiveness. Issues considered are the effect at different ages; components of interventions; work with peers; disciplinary methods, non-punitive and restorative approaches; challenges regarding cyberbullying; the role of parents; the role of teachers and teacher training; set menu versus à la carte approaches; sustainability of interventions and societal context. Conclusions show that interventions have had some success, with traditional bullying. However, further progress is needed in strengthening theoretical underpinnings to interventions, and in tackling cyberbullying.

Rapidly rising childhood obesity rates constitute a public health priority in Latin America which makes it imperative to develop evidence-based strategies. Schools are a promising setting but to date it is unclear how many school-based obesity interventions have been documented in Latin America and what level of evidence can be gathered from such interventions. We performed a systematic review of papers published between 1965 and December 2010. Interventions were considered eligible if they had a school-based component, were done in Latin America, evaluated an obesity related outcome (body mass index [BMI], weight, %body fat, waist circumference, BMI z-score), and compared youth exposed vs not exposed. Ten studies were identified as having a school-based component. Most interventions had a sample of normal and overweight children. The most successful interventions focused on prevention rather than treatment, had longer follow-ups, a multidisciplinary team, and fewer limitations in execution. Three prevention and 2 treatment interventions found sufficient improvements in obesity-related outcomes. We found sufficient evidence to recommend school-based interventions to prevent obesity among youth in Latin America. Evidence-based interventions in the school setting should be promoted as an important component for integrated programs, policies, and monitoring frameworks designed to reverse the childhood obesity in the region.

This paper relates to the first phase one of a three-phase study. Phase 1 investigated and identified risk factors for work-related musculoskeletal disorders (WMSDs) in 26 'One Tambon One Product' (OTOP) groups working in the informal sector. Data was collected from 93 participants in Khangkoi District, Saraburi Province, Thailand during 2009-2010. Results of inspections and direct observations of work places and interviews of managers and workers showed risk factors related to posture, repetition, force and duration in the workers' operations and the application of a checklist revealed that the OTOP groups had simple work processes. A knowledge-attitude-practice survey of managers and workers indicated that there was a moderate to high awareness regarding ergonomics and occupational safety and health principles and approximately 15% of workers reported WMSDs at a moderate level, mainly associated with lower back and shoulder pains, due to protracted periods of sitting. Specific recommendations in response to OTOP conditions and needs were made. The second phase of the study involves a participatory ergonomics worksite intervention by a number of stakeholders and the final phase deals with an evaluation of the intervention and an establishment of guidelines for ergonomics programs for OTOP groups.

Uptake of smoking in adolescence is still of major public health concern. Evaluations of school-based programmes for smoking prevention show mixed results. The aim of this study was to examine the effect of X:IT, a multi-component school-based programme to prevent adolescent smoking. Data from a Danish cluster randomized trial included 4041 year-7 students (mean age: 12.5) from 51 intervention and 43 control schools. Outcome measure 'current smoking' was dichotomized into smoking daily, weekly, monthly or more seldom vs do not smoke. Analyses were adjusted for baseline covariates: sex, family socioeconomic position (SEP), best friend's smoking and parental smoking. We performed multilevel, logistic regression analyses of available cases and intention-to-treat (ITT) analyses, replacing missing outcome values by multiple imputation. At baseline, 4.7% and 6.8% of the students at the intervention and the control schools smoked, respectively. After 1 year of the intervention, the prevalence was 7.9% and 10.7%, respectively. At follow-up, 553 students (13.7%) did not answer the question on smoking. Available case analyses: crude odds ratios (OR) for smoking at intervention schools compared with control schools: 0.65 (0.48-0.88) and adjusted: 0.70 (0.47-1.04). ITT analyses: crude OR for smoking at intervention schools compared with control schools: 0.67 (0.50-0.89) and adjusted: 0.61 (0.45-0.82). Students at intervention schools had a lower risk of smoking after a year of intervention in year 7. This multi-component intervention involving educational, parental and context-related intervention components seems to be efficient in lowering or postponing smoking uptake in Danish adolescents. © The Author 2015; all rights reserved.

Hignett, Sue; Wilson, John R; Morris, Wendy

2005-05-01

This paper gives an overview of the theory of participatory ergonomics interventions and summary examples from a range of industries, including health care, military, manufacturing, production and processing, services, construction and transport. The definition of participatory approaches includes interventions at macro (organizational, systems) levels as well as micro (individual), where workers are given the opportunity and power to use their knowledge to address ergonomic problems relating to their own working activities. Examples are given where a cost-effective benefit has been measured using musculoskeletal sickness absence and compensation costs. Other examples, using different outcome measures, also showed improvements, for example, an increase in productivity, improved communication between staff and management, reduction in risk factors, the development of new processes and new designs for work environments and activities. Three cases are described from Canada and Japan where the participatory project was led by occupational health teams, suggesting that occupational health practitioners can have an important role to play in participatory ergonomics projects.

Although the influence of organizational culture has been examined on a variety of student outcomes, few studies consider the influence that culture may have on school-based obesity prevention interventions. We present a systematic review of the literature to examine how elements of organizational culture may affect the adoption, implementation, and sustainability of school-based obesity prevention interventions. Fourteen studies examining the impact of organizational-level characteristics on school-based obesity prevention interventions were identified through the online databases EBSCO (CINAHL, ERIC, Agricola), Web of Science, Medline (PubMed), and Scopus. Five themes were identified as elements of organizational culture that influence the adoption, implementation, and sustainability of school-based obesity prevention interventions: organizational response to limited resources, value placed on staff training and professional development, internal support, organizational values, and school climate. Organizational culture can greatly influence the success of school-based obesity interventions. The collection of data related to organizational-level factors may be used to identify strategies for creating and sustaining a supportive environment for obesity prevention interventions in the school setting. © 2018, American School Health Association.

(1) BACKGROUND: Musculoskeletal disorders have a multifactorial etiology that is not only associated with physical risk factors, but also psychosocial risk factors; (2) OBJECTIVE: This study evaluated the effects of an ergonomic intervention on musculoskeletal disorders and psychosocial risk factors; (3) MATERIAL AND METHODS: This study took a participatory ergonomic (PE) approach with a randomized controlled trial (RCT) conducted at tertiary care hospitals during July to December 2014. A group of hospital orderlies in Thailand were randomly selected for examination. Fifty orderlies were placed in a case group and another 50 orderlies were placed in the control group. The Nordic Musculoskeletal Disorders Questionnaire (NMQ) and the Copenhagen Psychosocial Questionnaire (COPSOQ) were used for data collection before and after the intervention program; (4) RESULTS: The most commonly reported problem among hospital orderlies was found to be lower back symptoms (82%). The study found significant differences in prevalence rates of reported musculoskeletal conditions in the arm, upper back, and lower back regions before and after intervention. Findings showed that psychosocial risk factors were affected by the intervention. COPSOQ psychosocial risk factors were significantly different pre/post intervention. These variables included: work pace, influence at work, meaning of work, predictability, rewards, role conflicts, and social support from supervisors. No other psychosocial risk factors were found to be significant; (5) CONCLUSIONS: Positive results were observed following the intervention in the work environment, particularly in terms of reducing physical work environment risk factors for musculoskeletal disorders and increasing promotion factors of the psychosocial work environment.

Full Text Available A theoretical calculation model based on the ergonomic evaluation of team performance was proposed in order to carry out the ergonomic evaluation of the layout design schemes of the action station in a multitasking operational room. This model was constructed in order to calculate and compare the theoretical value of team performance in multiple layout schemes by considering such substantial influential factors as frequency of communication, distance, angle, importance, human cognitive characteristics and so on. An experiment was finally conducted to verify the proposed model under the criteria of completion time and accuracy rating. As illustrated by the experiment results,the proposed approach is conductive to the prediction and ergonomic evaluation of the layout design schemes of the action station during early design stages,and provides a new theoretical method for the ergonomic evaluation,selection and optimization design of layout design schemes.

A participatory ergonomics programme was implemented in an automotive parts manufacturing factory. An ergonomics change team was formed composed of members from management and the organized labour union. It was hypothesized that the physical change projects implemented as part of this process would result in decreased worker exposures to peak and cumulative physical demands and reduced worker perceptions of physical effort and pain severity. A quasi-experimental design was employed, utilizing a sister plant in the corporation as a referent group. A longitudinal questionnaire approach was used to document pre-post changes in worker perceptions. In general, the physical change projects were rated as improvements by workers and were successful at reducing peak and/or cumulative mechanical exposures. However, there were few systematic changes in perceived effort or pain severity levels. Explanations include the confounding effects of differential production rate and staffing changes at the intervention and referent plants and/or insufficient overall intervention intensity due to a relatively short intervention period, plant and team ambivalence towards the process and the low overall impact on exposure of the particular changes implemented.

Work-related musculoskeletal disorders (WRMDs) are recognized as a major source of significant pain and disability in the healthcare sector. However, they are preventable if appropriate surveillance and intervention programs are implemented. The purpose of this paper is to describe the holistic ergonomic approach that was used to address the multifactorial problems encountered by healthcare workers in their daily work. Using participatory ergonomics, healthcare workers in this study teamed up with management and staff with expertise in ergonomic analysis, design, and implementation of remedies. Selected participatory ergonomic intervention programs targeted at an organizational level are elaborated. Interventions included pre-work stretching, workplace surveillance at a psychiatric department, on-site ergonomic teaching for community nurses, and display screen equipment consultancy. Changes in workplace design, equipment re-arrangement, awareness of proper posture, and adoption of good work practices all play important roles in reducing musculoskeletal disorders among healthcare workers. Prompt occupational medicine and rehabilitation services were also provided to complement the work disability prevention process. The impact of the various intervention programs on staff health, costs and productivity of the organization are simultaneously discussed.

Full Text Available Background & Objectives : Currently, work-related musculoskeletal disorders are a major occupational health concern. This study tried to evaluate the risk factors of musculoskeletal disorders by the assessment of repetitive tasks (ART. It also sought to determine the effects of an ergonomic intervention on the mentioned risk in a manufacturing company . Methods: In this study, 60 production line workers were randomly selected. The data was collected by using a demographic questionnaire and the ART. The intervention was implemented for 39 cases. Data were analyzed in SPSS. Results: The initial evaluations suggested low, moderate, and high levels of risk in 21.7, 48.3, and 30.0 of the participants, respectively. Re-assessments after the intervention showed that the frequency of low-risk individuals increased from 30.70 before the intervention to 53.85 after the intervention. On the other hand, comparisons between the rates before and after the intervention revealed reductions in the frequency of moderate risk (64.10 vs. 43.59 and high risk (5.2 vs. 2.56. These changes were all significant. Conclusion: In most cases, the initial ergonomic risks were not at an acceptable level. In fact, most workers were at moderate level of risk. Since many workers in the assembling industry suffer from musculoskeletal disorders, low-cost eengineering and management measures can be taken to reduce the level of risk .

Few studies have rigorously evaluated school-based interventions to reduce violence and substance use in high school students, especially Latinos. This study assessed the effects of a school-based program on reducing violence and substance use among primarily Latino high school students. Ninth-grade students at risk for violence and substance use were randomized to intervention or control groups. The intervention was based on an existing program developed for white and African American youth. Data on smoking, alcohol and drug use, fighting, and grades were collected at baseline and 4 and 8 months post enrollment. There were 55 students in the control and 53 in the intervention group; 74% of controls and 78% of intervention students were Latino. There were no significant changes in fighting, smoking, or alcohol or drug use, from baseline to 8-month follow-up, between the intervention and control group. Pre and post grade point average (GPA) decreased from 2.3 at baseline to 1.8 at follow-up (pschool-based program showed no reduction in violence or substance use. The findings suggest that a program targeting non-Latino youth may not be optimal for reducing violence and substance use in Latinos; greater attention to cultural appropriateness and racial/ethnic differences may be needed. There was a decrease in intervention-group GPA but no significant change compared with controls. Further studies of the impact of school-based substance use and violence prevention programs on academics, and the effectiveness of afterschool or community-based programs compared to school-based programs are needed.

Production agriculture is commonly associated with high prevalence of ergonomic injuries, particularly during intensive manual labor and during harvesting. This paper intends to briefly describe an overview of oil palm plantation management highlighting the ergonomics problem each of the breakdown task analysis. Although cross-sectional field visits were conducted in the current study, insight into past and present occupational safety and health concerns particularly regarding the ergonomics of oil palm plantations was further exploited. Besides discussion, video recordings were extensively used for ergonomics analysis. The unique commodity of oil palm plantations presents significantly different ergonomics risk factors for fresh fruit bunch (FFB) cutters during different stages of harvesting. Although the ergonomics risk factors remain the same for FFB collectors, the intensity of manual lifting increases significantly with the age of the oil palm trees-weight of FFB. There is urgent need to establish surveillance in order to determine the current prevalence of ergonomic injuries. Thereafter, ergonomics interventions that are holistic and comprehensive should be conducted and evaluated for their efficacy using approaches that are integrated, participatory and cost-effective.

2017-09-01

A holistic review of ergonomic history shows that science remains important for general occupational health and safety (OSH), the broad society, culture, politics and the design of everyday things. Science provides an unconventional and multifaceted viewpoint exploring ergonomics from a social, corporate and OSH perspective. Ergonomic solutions from this mindset may redefine the science, and it will change with companies that change within this socially hyper-connected world. Authentic corporate social responsibility will counter 'misleadership' by not approaching ergonomics with an afterthought. The review concludes that ergonomics will be stronger with social respect and ergonomic thinking based on the optimisation of anthropometric data, digital human models, computer-aided tools, self-empowerment, job enrichment, work enlargement, physiology, industrial psychology, cybernetic ergonomics, operations design, ergonomic-friendly process technologies, ergonomic empowerment, behaviour-based safety, outcome-based employee wellness and fatigue risk management solutions, to mention a few.

Community stroke awareness initiatives have traditionally been used to expand knowledge of stroke signs and risk factors to high-risk adult populations. Here, we use a novel unfettered, visual art-based approach for an elementary school initiative to raise stroke awareness. Seventh graders in a middle school art class received stroke awareness training during the course of the 2015 to 2016 school year through their teacher in the visual arts class. In turn, they used this training to develop their own artistic interpretations of key stroke awareness concepts via project-based learning and then present their projects to raise awareness about stroke. We evaluated our predata and postdata to determine whether the visual art school-based stroke intervention was effective in both educating students about stroke and enabling them to effectively disseminate this information to parents and other adults in their community. The pretest evaluation indicates a fair or good knowledge about stroke, and no student indicated an "outstanding" or "excellent" knowledge. The posttest evaluation indicated a higher degree of stroke awareness because students were rated as having an "outstanding," "excellent," or "very good" performance especially in the ability to translate knowledge of stroke awareness lessons learned in their art class into a well-articulated stroke-related project and presentation. Pearson χ test reveals significant difference (P art teacher to lead the educational component in the intervention indicates that expertise in neurology or stroke is not necessary to facilitate understanding of stroke and highlights the importance of creativeness in stroke education for children.

In the emerging debate around obesity intervention in schools, recent calls have been made for researchers to include local community opinions in the design of interventions. Community-based participatory research (CBPR) is an effective approach for forming community partnerships and integrating local opinions. We used CBPR principles to conduct formative research in identifying acceptable and potentially sustainable obesity intervention strategies in 8 New Mexico school communities. We collected formative data from 8 high schools on areas of community interest for school health improvement through collaboration with local School Health Advisory Councils (SHACs) and interviews with students and parents. A survey based on formative results was created to assess acceptability of specific intervention strategies and was provided to SHACs. Quantitative data were analyzed using descriptive statistics while qualitative data were evaluated using an iterative analytic process for thematic identification. Key themes identified through the formative process included lack of healthy food options, infrequent curricular/extracurricular physical activity opportunities, and inadequate exposure to health/nutritional information. Key strategies identified as most acceptable by SHAC members included healthier food options and preparation, a healthy foods marketing campaign, yearly taste tests, an after-school noncompetitive physical activity program, and community linkages to physical activity opportunities. An adaptive CBPR approach for formative assessment can be used to identify obesity intervention strategies that address community school health concerns. Eight high school SHACs identified 6 school-based strategies to address parental and student concerns related to obesity. © 2012, American School Health Association.

Schools and school systems are increasingly asked to use evidence-based strategies to promote the health and well-being of students. The dissemination of school-based health promotion research, however, offers particular challenges to conventional approaches to dissemination. Schools and education systems are multifaceted organizations that sit within constantly shifting broader contexts. This article argues that health promotion dissemination needs to be rethought for school communities as complex systems and that this requires understanding and harnessing the dynamic ecology of the sociopolitical context. In developing this argument, the authors draw on their experience of the dissemination process of a multilevel school-based intervention in a complex educational context. Building on this experience, they argue for the need to move beyond conventional dissemination strategies to a focus on active partnerships between developers and users of school-based intervention research and offer a conceptual tool for planning dissemination.

Although schools have been trying to address bulling by utilizing different approaches that stop or reduce the incidence of bullying, little remains known about what specific intervention strategies are most successful in reducing bullying in the school setting. Using the social-ecological framework, this paper examines school-based disciplinary interventions often used to deliver consequences to deter the reoccurrence of bullying and aggressive behaviors among school-aged children. Data for this study are drawn from the School-Wide Information System (SWIS) with the final analytic sample consisting of 1,221 students in grades K – 12 who received an office disciplinary referral for bullying during the first semester. Using Kaplan-Meier Failure Functions and Multi-level discrete time hazard models, determinants of the probability of a student receiving a second referral over time were examined. Of the seven interventions tested, only Parent-Teacher Conference (AOR=0.65, pbullying and aggressive behaviors. By using a social-ecological framework, schools can develop strategies that deter the reoccurrence of bullying by identifying key factors that enhance a sense of connection between the students’ mesosystems as well as utilizing disciplinary strategies that take into consideration student’s microsystem roles.

To evaluate a brief oral health promotion intervention delivered in schools by a primary care dental practice, aimed at changing oral health care knowledge and oral health-related behaviors in children. Cohort study with pretest-posttest design. Three primary schools. One hundred and fifty children (aged 9-12 years). Children received a 60-minute theory-driven classroom-based interactive educational session delivered by a dental care professional and received take-home literature on oral health. All children completed a questionnaire on oral health-related knowledge and self-reported oral health-related behaviors before, immediately after, and 6 weeks following the intervention. Children's dental knowledge significantly improved following the intervention, with improvement evident at immediate follow-up and maintained 6 weeks later. Significantly more children reported using dental floss 6 weeks after the intervention compared with baseline. No significant differences were detected in toothbrushing or dietary behaviors. School-based preventative oral health education delivered by primary care dental practices can generate short-term improvements in children's knowledge of oral health and some aspects of oral hygiene behavior. Future research should engage parents/carers and include objective clinical and behavioral outcomes in controlled study designs. © 2014 Society for Public Health Education.

The aim of the study was to investigate the connections between voice ergonomic risk factors found in classrooms and voice-related problems in teachers. Voice ergonomic assessment was performed in 39 classrooms in 14 elementary schools by means of a Voice Ergonomic Assessment in Work Environment--Handbook and Checklist. The voice ergonomic risk factors assessed included working culture, noise, indoor air quality, working posture, stress, and access to a sound amplifier. Teachers from the above-mentioned classrooms reported their voice symptoms, respiratory tract diseases, and completed a Voice Handicap Index (VHI). The more voice ergonomic risk factors found in the classroom the higher were the teachers' total scores on voice symptoms and VHI. Stress was the factor that correlated most strongly with voice symptoms. Poor indoor air quality increased the occurrence of laryngitis. Voice ergonomics were poor in the classrooms studied and voice ergonomic risk factors affected the voice. It is important to convey information on voice ergonomics to education administrators and those responsible for school planning and taking care of school buildings.

The objective of this paper was to control ergonomic risks among female cashiers working in a department store belonging to the retail market. This study was conducted between May and November 2010. Participatory ergonomics was applied through knowing and understanding how the company works, establishing the work team (Ergo group), training the team in ergonomics-related topics, and making decisions and interventions. The sample was composed of 71 participants--mostly female cashiers--, and all of them have a musculoskeletal compromise, declaring pain or discomfort mainly in the neck, lower back, right wrist and shoulders. Among others, following problems were found: postural overload, repetitive work, manual load handling, mental fatigue, environmental discomfort, variable work schedules, extended working days, and absence of breaks. In the intervention, the main implemented changes were the redesign of workstation, complete change of chairs and keyboards, and the implementation of a rotation system, as well breaks for compensatory exercises. After that, an evident improvement of found problems was observed, therefore it can be concluded that participatory ergonomics is an attractive methodology, appropriate and efficient for solving and controlling ergonomic risks and problems.

A spinal board is the evacuation tool of first aid to help the injured spinal cord. The existing spinal board has several weaknesses, both in terms of user comfort and the effectiveness and efficiency of the evacuation process. This study designs an ergonomic spinal board using the quality function deployment approach. A preliminary survey was conducted through direct observation and interviews with volunteers from the Indonesian Red Cross. Data gathered were translated into a questionnaire and answered by 47 participants in West Sumatra. The results indicate that the selection of materials, the application of strap systems as well as the addition of features are very important in designing an ergonomic spinal board. The data were used in designing an ergonomic spinal board. The use of anthropometric data ensures that this product can accommodate safety and comfort when immobilized, as well as the flexibility and speed of the rescue evacuation process.

Anxiety disorders are prevalent among adolescents and may have long-lasting negative consequences for the individual, the family and society. Cognitive behavioral therapy (CBT) is an effective treatment. However, many anxious youth do not seek treatment. Low-intensity CBT in schools may improve access to evidence-based services. We aim to investigate the efficacy of two CBT youth anxiety programs with different intensities (i.e., number and length of sessions), both group-based and administered as early interventions in a school setting. The objectives of the study are to examine the effects of school-based interventions for youth anxiety and to determine whether a less intensive intervention is non-inferior to a more intensive intervention. The present study is a randomized controlled trial comparing two CBT interventions to a waitlist control group. A total of 18 schools participate and we aim to recruit 323 adolescents (12-16 years). Youth who score above a cutoff on an anxiety symptom scale will be included in the study. School nurses recruit participants and deliver the interventions, with mental health workers as co-therapists and/or supervisors. Primary outcomes are level of anxiety symptoms and anxiety-related functional impairments. Secondary outcomes are level of depressive symptoms, quality of life and general psychosocial functioning. Non-inferiority between the two active interventions will be declared if a difference of 1.4 or less is found on the anxiety symptom measure post-intervention and a difference of 0.8 on the interference scale. Effects will be analyzed by mixed effect models, applying an intention to treat procedure. The present study extends previous research by comparing two programs with different intensity. A brief intervention, if effective, could more easily be subject to large-scale implementation in school health services. ClinicalTrials.gov, NCT02279251 . Registered on 15 October 2014.

The lack of physical activity and increasing time spent in sedentary behaviours during childhood place importance on developing low cost, easy-toimplement school-based interventions to increase physical activity among children. The PREVIENE Project will evaluate the effectiveness of five innovative, simple, and feasible interventions (active commuting to/from school, active Physical Education lessons, active school recess, sleep health promotion, and an integrated program incorporating all 4 interventions) to improve physical activity, fitness, anthropometry, sleep health, academic achievement, and health-related quality of life in primary school children. A total of 300 children (grade 3; 8-9 years of age) from six schools in Granada (Spain) will be enrolled in one of the 8-week interventions (one intervention per school; 50 children per school) or a control group (no intervention school; 50 children). Outcomes will include physical activity (measured by accelerometry), physical fitness (assessed using the ALPHA fitness battery), and anthropometry (height, weight and waist circumference). Furthermore, they will include sleep health (measured by accelerometers, a sleep diary, and sleep health questionnaires), academic achievement (grades from the official school's records), and health-related quality of life (child and parental questionnaires). To assess the effectiveness of the different interventions on objectively measured PA and the other outcomes, the generalized linear model will be used. The PREVIENE Project will provide the information about the effectiveness and implementation of different school-based interventions for physical activity promotion in primary school children.

Full Text Available In the view of the current cockpit information interaction, facilities and other characteristics are increasingly multifarious; the early layout evaluation methods based on single or partial components, often cause comprehensive evaluation unilateral, leading to the problems of long development period and low efficiency. Considering the fuzziness of ergonomic evaluation and diversity of evaluation information attributes, we refine and build an evaluation system based on the characteristics of the current cockpit man-machine layout and introduce the different types of uncertain linguistic multiple attribute combination decision making (DTULDM method in the cockpit layout evaluation process. Meanwhile, we also establish an aircraft cockpit ergonomic layout evaluation model. Finally, an experiment about cockpit layout evaluation is given, and the result demonstrates that the proposed method about cockpit ergonomic layout evaluation is feasible and effective.

2016-01-01

Cyberbullying is an emerging form of bullying that takes place through contemporary information and communication technologies. Building on past research on the psychosocial risk factors for cyberbullying in this age group, the present study assessed a theory-driven, school-based preventive intervention that targeted moral disengagement, empathy and social cognitive predictors of cyberbullying. Adolescents (N = 355) aged between 16 and 18 years were randomly assigned into the intervention and the control group. Both groups completed anonymous structured questionnaires about demographics, empathy, moral disengagement and cyberbullying-related social cognitive variables (attitudes, actor prototypes, social norms, and behavioral expectations) before the intervention, post-intervention and 6 months after the intervention. The intervention included awareness-raising and interactive discussions about cyberbullying with intervention group students. Analysis of covariance (ANCOVA) showed that, after controlling for baseline measurements, there were significant differences at post-intervention measures in moral disengagement scores, and in favorability of actor prototypes. Further analysis on the specific mechanisms of moral disengagement showed that significant differences were observed in distortion of consequences and attribution of blame. The implications of the intervention are discussed, and guidelines for future school-based interventions against cyberbullying are provided. © 2015 Wiley Periodicals, Inc.

Methods A total of 300 children (grade 3; 8-9 years of age from six schools in Granada (Spain will be enrolled in one of the 8-week interventions (one intervention per school; 50 children per school or a control group (no intervention school; 50 children. Outcomes will include physical activity (measured by accelerometry, physical fitness (assessed using the ALPHA fitness battery, and anthropometry (height, weight and waist circumference. Furthermore, they will include sleep health (measured by accelerometers, a sleep diary, and sleep health questionnaires, academic achievement (grades from the official school’s records, and health-related quality of life (child and parental questionnaires. To assess the effectiveness of the different interventions on objectively measured PA and the other outcomes, the generalized linear model will be used. Discussion The PREVIENE Project will provide the information about the effectiveness and implementation of different school-based interventions for physical activity promotion in primary school children.

A uniform approach for costing school-based lifestyle interventions is currently lacking. The objective of this study was to develop a template for costing primary school-based lifestyle interventions and apply this to the costing of the "Healthy Primary School of the Future" (HPSF) and the "Physical Activity School" (PAS), which aim to improve physical activity and dietary behaviors. Cost-effectiveness studies were reviewed to identify the cost items. Societal costs were reflected by summing up the education, household and leisure, labor and social security, and health perspectives. Cost inputs for HPSF and PAS were obtained for the first year after implementation. In a scenario analysis, the costs were explored for a hypothetical steady state. From a societal perspective, the per child costs were €2.7/$3.3 (HPSF) and €- 0.3/$- 0.4 (PAS) per day during the first year after implementation, and €1.0/$1.2 and €- 1.3/$- 1.6 in a steady state, respectively (2016 prices). The highest costs were incurred by the education perspective (first year: €8.7/$10.6 (HPSF) and €4.0/$4.9 (PAS); steady state: €6.1/$7.4 (HPSF) and €2.1/$2.6 (PAS)), whereas most of the cost offsets were received by the household and leisure perspective (first year: €- 6.0/$- 7.3 (HPSF) and €- 4.4/$- 5.4 (PAS); steady state: €- 5.0/$- 6.1 (HPSF) and €- 3.4/$- 4.1 (PAS)). The template proved helpful for costing HPSF and PAS from various stakeholder perspectives. The costs for the education sector were fully (PAS) and almost fully (HPSF) compensated by the savings within the household sector. Whether the additional costs of HPSF over PAS represent value for money will depend on their relative effectiveness.

Background Sufficient sleep during childhood is essential to ensure a transition into a healthy adulthood. However, chronic sleep loss continues to increase worldwide. In this context, it is imperative to make sleep a high-priority and take action to promote sleep health among children. The present series of studies aimed to shed light on sleep patterns, on the longitudinal association of sleep with school performance, and on practical intervention strategy for Chinese school-aged children. Methods and Findings A serial sleep researches, including a national cross-sectional survey, a prospective cohort study, and a school-based sleep intervention, were conducted in China from November 2005 through December 2009. The national cross-sectional survey was conducted in 8 cities and a random sample of 20,778 children aged 9.0±1.61 years participated in the survey. The five-year prospective cohort study included 612 children aged 6.8±0.31 years. The comparative cross-sectional study (baseline: n = 525, aged 10.80±0.41; post-intervention follow-up: n = 553, aged 10.81±0.33) was undertaken in 6 primary schools in Shanghai. A battery of parent and teacher reported questionnaires were used to collect information on children’s sleep behaviors, school performance, and sociodemographic characteristics. The mean sleep duration was 9.35±0.77 hours. The prevalence of daytime sleepiness was 64.4% (sometimes: 37.50%; frequently: 26.94%). Daytime sleepiness was significantly associated with impaired attention, learning motivation, and particularly, academic achievement. By contrast, short sleep duration only related to impaired academic achievement. After delaying school start time 30 minutes and 60 minutes, respectively, sleep duration correspondingly increased by 15.6 minutes and 22.8 minutes, respectively. Moreover, intervention significantly improved the sleep duration and daytime sleepiness. Conclusions Insufficient sleep and daytime sleepiness commonly existed and

This study describes a culturally sensitive approach to engage Mexican origin families in a school-based, family-focused preventive intervention trial. The approach was evaluated via assessing study enrollment and intervention program participation, as well as examining predictors of engagement at each stage. Incorporating traditional cultural values into all aspects of engagement resulted in participation rates higher than reported rates of minority-focused trials not emphasizing cultural sensitivity. Family preferred language (English or Spanish) or acculturation status predicted engagement at all levels, with less acculturated families participating at higher rates. Spanish-language families with less acculturated adolescents participated at higher rates than Spanish-language families with more acculturated adolescents. Other findings included two-way interactions between family language and the target child’s familism values, family single- vs. dual-parent status, and number of hours the primary parent worked in predicting intervention participation. Editors’ Strategic Implications: The authors present a promising approach—which requires replication—to engaging and retaining Mexican American families in a school-based prevention program. The research also highlights the importance of considering acculturation status when implementing and studying culturally tailored aspects of prevention models. PMID:18004659

School-Based Interventions Going Beyond Health Education to Promote Adolescent Health: Systematic Review of Reviews.

Health education in school classrooms can be effective in promoting sexual health and preventing violence and substance use but effects are patchy and often short term. Classroom education is also challenging because of schools' increasing focus on academic-performance metrics. Other school-based approaches are possible, such as healthy school policies, improving how schools respond to bullying, and parent outreach, which go beyond health education to address broader health determinants. Existing systematic reviews include such interventions but often alongside traditional health education. There is scope for a systematic review of reviews to assess and synthesize evidence across existing reviews to develop an overview of the potential of alternative school-based approaches. We searched 12 databases to identify reviews published after 1980. Data were reviewed by two researchers. Quality was assessed using a modified Assessing the Methodological Quality of Systematic Reviews checklist and results were synthesized narratively. We screened 7,544 unique references and included 22 reviews. Our syntheses suggest that multicomponent school-based interventions, for example, including school policy changes, parent involvement, and work with local communities, are effective for promoting sexual health and preventing bullying and smoking. There is less evidence that such intervention can reduce alcohol and drug use. Economic incentives to keep girls in school can reduce teenage pregnancies. School clinics can promote smoking cessation. There is little evidence that, on their own, sexual-health clinics, antismoking policies, and various approaches targeting at-risk students are effective. There is good evidence that various whole-school health interventions are effective in preventing teenage pregnancy, smoking, and bullying.

Contextual factors affecting task distribution in two participatory ergonomic interventions: a qualitative study.

Science.gov (United States)

Dixon, Shane Michael; Theberge, Nancy

2011-11-01

This article provides an analysis of the evolution of the division of labour in participatory ergonomics (PE) programmes in two worksites. The analysis is based on interviews and field observations in the worksites. In both settings there was meaningful participation by both worker and management members of ergonomic change teams (ECTs) in the hazard assessment and solution identification stages, but as the teams moved to the implementation stage, worker representatives were marginalised and the participatory nature of the programmes was severely curtailed. The removal of workers from the process was the outcome of the interplay among the type of activities pursued in the implementation stage, the skills and knowledge required to carry out those activities, and workers' limited influence in the organisational hierarchies. Findings highlight the salience of the social context in which participatory programmes are located and the importance of examining participatory programmes as they evolve over time. STATEMENT OF RELEVANCE: This article contributes to a growing literature on the process and implementation of PE programmes. The article's focus on social and organisational factors that affect the division of labour and attention to the evolution of involvement over time extend current understandings of participation in ergonomics programmes.

School-Based Interventions to Reduce Obesity Risk in Children in High- and Middle-Income Countries.

Evans, Charlotte E L; Albar, Salwa Ali; Vargas-Garcia, Elisa J; Xu, Fei

2015-01-01

School-based interventions are relatively new and were first introduced in the United States in the 1990s. Early programs were mainly education based with many of the findings now embedded in school policy in the form of a healthy eating curriculum. More recent school programs have taken education outside the classroom and attempted to engage parents as well as teachers. Environmental changes such as improving the quality of foods available at lunchtime and at other times during the school day are now common. Reviews of evaluations of school-based programs have demonstrated that they are effective and successfully improve dietary quality such as increasing fruit and vegetable intake and decreasing sweet and savory snacks and sweetened drinks; not just in school but over the whole day and particularly in younger school children. School-based interventions are also effective at reducing obesity if components to increase physical activity and reduce sedentary behaviors are also targeted but not if only dietary behaviors are tackled. Most of the high-quality evaluation studies using randomized controlled trials have been carried out in high-income countries as they are costly to run. However, middle-income countries have benefitted from the information available from these evaluation studies and many are now starting to fund and evaluate school-based programs themselves, resulting in unique problems such as concomitant under- and overnutrition being addressed. Action for the future demands more focus on populations most at risk of poor dietary quality and obesity in order to reduce inequalities in health and on adolescents who have not benefited as much as younger children from school-based interventions. This will involve innovative solutions within schools as well as targeting the food environment outside schools such as reducing the density of fast-food outlets and marketing of sweet and savory snacks and drinks. © 2015 Elsevier Inc.

Full Text Available Abstract Background Masons have the highest rate of overexertion injuries among all construction trades and rank second for occupational back injuries in the United States. Identified ergonomic solutions are the primary method of reducing exposure to risk factors associated with musculoskeletal disorders. However, many construction workers lack knowledge about these solutions, as well as basic ergonomic principles. Construction apprentices, as they embark on their careers, are greatly in need of ergonomics training to minimize the cumulative exposure that leads to musculoskeletal disorders. Apprentices receive safety training; however, ergonomics training is often limited or non-existent. In addition, apprenticeship programs often lack “soft skills” training on how to appropriately respond to work environments and practices that are unsafe. The SAVE program – SAfety Voice for Ergonomics – strives to integrate evidence-based health and safety training strategies into masonry apprenticeship skills training to teach ergonomics, problem solving, and speaking up to communicate solutions that reduce musculoskeletal injury risk. The central hypothesis is that the combination of ergonomics training and safety voice promotion will be more effective than no training or either ergonomics training alone or safety voice training alone. Methods/design Following the development and pilot testing of the SAVE intervention, SAVE will be evaluated in a cluster-randomized controlled trial at 12 masonry training centers across the U.S. Clusters of apprentices within centers will be assigned at random to one of four intervention groups (n = 24 per group: (1 ergonomics training only, (2 safety voice training only, (3 combined ergonomics and safety voice training, or (4 control group with no additional training intervention.

Green ergonomics: combining sustainability and ergonomics.

Pilczuk, Davana; Barefield, Kevin

When discussing ergonomics, the term 'sustainability' usually refers to the preservation of the human workforce. However, in 2010 Gulfstream Aerospace Corporation made a conscious effort to combine ergonomics and environmental sustainability in order to increase employee engagement for both programs. They introduced a companywide campaign called Green Ergo which is the idea of creating ergonomic solutions from scrap material found on site. This concept embraced the true meaning of 'green' and encouraged engineers and employees all across the company to design innovative green ergonomic solutions. The idea generated over 35 new ergo solutions, reduced waste production, and solved over 700 ergo problems for a fraction of the cost of newly purchased items. The demand for these items grew large enough that the company outsourced their manufacturing to a local non-profit. The Green Ergo campaign has changed the culture of the company and has increased the level of buy-in for both the ergonomics and sustainability programs.

Translating concepts of complexity to the field of ergonomics.

Walker, Guy H; Stanton, Neville A; Salmon, Paul M; Jenkins, Daniel P; Rafferty, Laura

2010-10-01

Since 1958 more than 80 journal papers from the mainstream ergonomics literature have used either the words 'complex' or 'complexity' in their titles. Of those, more than 90% have been published in only the past 20 years. This observation communicates something interesting about the way in which contemporary ergonomics problems are being understood. The study of complexity itself derives from non-linear mathematics but many of its core concepts have found analogies in numerous non-mathematical domains. Set against this cross-disciplinary background, the current paper aims to provide a similar initial mapping to the field of ergonomics. In it, the ergonomics problem space, complexity metrics and powerful concepts such as emergence raise complexity to the status of an important contingency factor in achieving a match between ergonomics problems and ergonomics methods. The concept of relative predictive efficiency is used to illustrate how this match could be achieved in practice. What is clear overall is that a major source of, and solution to, complexity are the humans in systems. Understanding complexity on its own terms offers the potential to leverage disproportionate effects from ergonomics interventions and to tighten up the often loose usage of the term in the titles of ergonomics papers. STATEMENT OF RELEVANCE: This paper reviews and discusses concepts from the study of complexity and maps them to ergonomics problems and methods. It concludes that humans are a major source of and solution to complexity in systems and that complexity is a powerful contingency factor, which should be considered to ensure that ergonomics approaches match the true nature of ergonomics problems.

Schools play an important role in promoting the health of children. However, little consideration is often given to the influence that headteachers' and school staff's prior beliefs have on the implementation of public health interventions. This study examined primary school headteachers' and school health co-ordinators' views regarding child health in order to provide greater insights on the school's perspective for those designing future school-based health interventions. A qualitative study was conducted using 19 semi-structured interviews with headteachers, deputy headteachers and school health co-ordinators in the primary school setting. All transcripts were analysed using thematic analysis. Whilst many participants in this study believed good health was vital for learning, wide variance was evident regarding the perceived health of school pupils and the magnitude of responsibility schools should take in addressing child health behaviours. Although staff in this study acknowledged the importance of their role, many believed the responsibility placed upon schools for health promotion was becoming too much; suggesting health interventions need to better integrate school, parental and societal components. With mental health highlighted as an increasing priority in many schools, incorporating wellbeing outcomes into future school based health interventions is advocated to ensure a more holistic understanding of child health is gained. Understanding the health beliefs of school staff when designing interventions is crucial as there appears to be a greater likelihood of interventions being successfully adopted if staff perceive a health issue as important among their pupils. An increased dependability on schools for addressing health was expressed by headteachers in this study, highlighting a need for better understanding of parental, child and key stakeholder perspectives on responsibility for child health. Without this understanding, there is potential for certain

Armed conflicts are associated with a wide range of impacts on the mental health of children and adolescents. We evaluated the effectiveness of a school-based intervention aimed at reducing symptoms of posttraumatic stress disorder, depression, and anxiety (treatment aim); and improving a sense of hope and functioning (preventive aim). We conducted a cluster randomized trial with 329 children in war-affected Burundi (aged 8 to 17 (mean 12.29 years, standard deviation 1.61); 48% girls). One group of children (n = 153) participated in a 15-session school-based intervention implemented by para-professionals, and the remaining 176 children formed a waitlist control condition. Outcomes were measured before, one week after, and three months after the intervention. No main effects of the intervention were identified. However, longitudinal growth curve analyses showed six favorable and two unfavorable differences in trajectories between study conditions in interaction with several moderators. Children in the intervention condition living in larger households showed decreases on depressive symptoms and function impairment, and those living with both parents showed decreases on posttraumatic stress disorder and depressive symptoms. The groups of children in the waitlist condition showed increases in depressive symptoms. In addition, younger children and those with low levels of exposure to traumatic events in the intervention condition showed improvements on hope. Children in the waitlist condition who lived on their original or newly bought land showed improvements in hope and function impairment, whereas children in the intervention condition showed deterioration on these outcomes. Given inconsistent effects across studies, findings do not support this school-based intervention as a treatment for posttraumatic stress disorder and depressive symptoms in conflict-affected children. The intervention appears to have more consistent preventive benefits, but these effects are

Study design This is a cluster randomised controlled trial with schools as the main clusters. We compared this intervention with a control group in a study involving 22 schools, 66 classes and approximately 2,600 students. Students in the active schools attended 11 weekly and 3 booster sessions of an intervention based on cognitive-behavioural models. The control schools received their usual but enhanced counselling sessions currently included in their curriculum. Mean depression scores and indicators of levels of functioning were assessed at 3 and 12 months after the completion of the intervention in order to assess the effectiveness of the intervention. Direct and indirect costs were measured in both groups to assess the cost-effectiveness of this intervention. Discussion As far as we are aware this is the first cluster randomised controlled trial of a school intervention for depression among adolescents outside the Western world.

Ergonomic Risk Factors (ERFs) which contribute to Musculoskeletal Disorders (MSDs) among room attendants were considered as a problem or trouble since these ERFs would affect their work performance for hotel industries. The purpose of this study was to examine the exposure level of ERFs among room attendants in hotel industries. 65 of respondents were obtained from selected hotels in Peninsular Malaysia. Data were collected by direct observation via Workplace Ergonomic Risk Assessment (WERA) and Quick Exposure Checklist (QEC). There were 36 males and 29 females room attendants involved throughout the research. Most of room attendants experienced high exposure level for back, leg, forceful and vibration based on the exposure level evaluation through WERA while QEC results showed that all room attendants were found to have moderate exposure level for risk factors including back for movement use, shoulders/arms, wrists/hands and neck. All the results obtained showed that the related ERFs for MSDs were associated and essential ergonomic interventions are needed in order to eliminate risk of exposures to MSDs among room attendants in hotel industries.

Occupational ergonomics and injury prevention.

Ergonomics is the study of people at work. The current focus is on the prevention of work-induced musculoskeletal injuries through the application of sound ergonomic principles. This chapter has briefly outlined ergonomics and its history, has described low back pain and upper extremity cumulative trauma disorders from an ergonomic perspective, and has discussed control and prevention approaches for a few scenarios. Ergonomic principles are based on a combination of science and engineering and a thorough understanding of human capabilities and limitations. When these principles are applied to the design of a job, task, process, or procedure, the incidence and severity of musculoskeletal injuries decrease. In many cases productivity and morale also improve. Workers are spared suffering, and employers are spared costs. It is hoped that this discussion will encourage more health, safety, and business professionals to learn about and apply ergonomics in their workplaces for the improvement of the worker, product, and business. Finally, many additional epidemiologic studies on the individual and joint effects of the CTD risk factors are needed. The knowledge gained from these studies will promote the more effective application of ergonomic principles to reduce worker suffering, improve products, and reduce costs.

Manufacturing industry workers who repair computers may be exposed to ergonomic risk factors. This project analyzes the tasks involved in the computer repair process to (1) find the risk level for musculoskeletal disorders (MSDs) and (2) propose ergonomic interventions to address any ergonomic issues. Work procedures and main body postures were video recorded and analyzed using task analysis, the Rapid Entire Body Assessment (REBA) postural method, and biomechanical analysis. High risk for MSDs was found on every subtask using REBA. Although biomechanical analysis found an acceptable mass center displacement during tasks, a hazardous level of compression on the lower back during computer's transportation was detected. This assessment found ergonomic risks mainly in the trunk, arm/forearm, and legs; the neck and hand/wrist were also compromised. Opportunities for ergonomic analyses and interventions in the design and execution of computer repair tasks are discussed.

Intervention studies in participatory ergonomics (PE) are often difficult to interpret due to limited descriptions of program planning and evaluation. In an ongoing PE program with floor layers, we developed a logic model to describe our program plan, and process and summative evaluations designed to describe the efficacy of the program. The logic model was a useful tool for describing the program elements and subsequent modifications. The process evaluation measured how well the program was delivered as intended, and revealed the need for program modifications. The summative evaluation provided early measures of the efficacy of the program as delivered. Inadequate information on program delivery may lead to erroneous conclusions about intervention efficacy due to Type III error. A logic model guided the delivery and evaluation of our intervention and provides useful information to aid interpretation of results. © 2013 Wiley Periodicals, Inc.

2012-02-01

The purpose of this article is to provide some perspectives on Lilienfeld, Ammirati, and David's (2012) paper on distinguishing science from pseudoscience in school psychology. In many respects their work represents an intervention for "grandiose bragging," a problem that has occasionally occurred when various non-evidence-based or discredited interventions receive sensationalized positive endorsement for adoption in school psychology practice. In this paper, the implications of the Lilienfeld et al. work are discussed within the context of the scientist-practitioner gap, scientific thinking and evaluation of scientific thinking, and negative results research. The authors have advanced our thinking on evidence-based practices in school psychology and education. Copyright © 2011 Society for the Study of School Psychology. Published by Elsevier Ltd.

This paper describes the different strategic understanding from getting ergonomics intervention programmes' conversations to 'Tip', including minimizing strategies; tipping point strategies; and maximizing strategies from building ergonomics intervention techniques. Those have indicated to different recognitions: 1) when amplification of the 'problem' is necessary; 2) when amplification of the 'tipping point' is necessary, and 3) when amplification of the 'success' is necessary. The practical applications and implications of the ergonomics intervention techniques are drawn from the findings of framing positive questions: 1) what is successful ergonomics intervention technique right now (Appreciative)? 2) What do we need to change for a better future (Imagine)? 3) How do we do this (Design)? 4) Who takes action and with what consequences (Act)? This requires re-framing of the ergonomics intervention techniques in an appreciative way, because of, the future action needs to be inspired by those things that participants feel are worth valuing, worth celebrating and sustaining.

The objectives were to identify the impact of ergonomic work environment exposures on the risk of disability pension. A representative sample of 8475 employees of the total working population in Denmark were interviewed regarding work environment exposures and followed in a national register with data on granted disability pension. For women, approximately 34% of the disability pension cases were attributable to ergonomic work environment exposures. For men, 21% of the disability pension cases were attributable to ergonomic work environment. Ergonomic work environment, especially physically demanding work, working with hands lifted and repetitive work, are areas of intervention at the workplace that can facilitate and prolong labour market participation. The study provides estimates for the association between ergonomic exposures at work and administrative, cost-related measures of work disability in a large population-based longitudinal cohort study over 14 years. Approximately 21% for men and 34% for women of the disability pension cases were attributable to ergonomic work environment exposures.

The factory capacity achievement and the bottleneck reduction of production process at wet-blanket workstations are influenced by the balance of life quality rates and worker’s productivity, along with the worker’s ability and limitations, tasks, organization and work environment. The life quality of workers is indicated by: the reduction of workload, and fatigue. Meanwhile, work productivity is measured by increasing production results per work shift. The optimization of the quality of life and productivity of workers is achieved by redesigning the system and workstations based on ergonomics integrating Total Ergonomics with Ergo-MicMac (Micro Ergonomics and Macro Ergonomics), which includes redesigning wet-blanket folding worktable, regulating the system pattern of working in pairs, giving official break time, giving extra nutritious intakes such as sweet tea and snack Pempek, giving personal protective equipments, and redesigning physical working environments.This study was an experimental study, with treatment by subject design involving 30 workers sampled at a workstation condition before and after Ergonomics based redesign. The findings and conclusions of the study were derived from the reduction of the workload by 16.06%, fatigue by 18.84% and the increase of production results per work shift by 20.29%.

The prevalence of non-communicable diseases (NCDs) is increasing worldwide, also among children. Information about primary prevention of NCD's is increasing; however, convincing strategies among children is needed. The present paper describes the design and methods in the Health Oriented Pedagogical Project (HOPP) study. The main objective is to evaluate the effects of a school-based physical activity intervention program on cardio-metabolic risk factors. Secondary objectives include assessment of physical, psychological and academic performance variables. The HOPP study is a 7 years longitudinal large-scale controlled intervention in seven elementary schools (n = 1545) with two control schools (n = 752); all aged 6-11 years at baseline. The school-based physical activity intervention program includes an increase in physical activity (PA) of 225 min/week as an integrated part of theoretical learning, in addition to the curriculum based 90 min/week of ordinary PA. Primary outcomes include cardio-metabolic risk factors measured as PA level, BMI status, waist circumference, muscle mass, percent fat, endurance test performance, total serum cholesterol, high-density lipoprotein (HDL), non-HDL, micro C-reactive protein (mCRP) and long-term blood sugar (HbA1c). In addition, secondary outcomes include anthropometric growth measures, physical fitness, quality of life (QoL), mental health, executive functions, diet and academic performance. HOPP will provide evidence of effects on cardio-metabolic risk factors after a long-term PA intervention program in elementary schoolchildren. School-based PA intervention programs may be an effective arena for health promotion and disease prevention. The study is registered in Clinical trials (ClinicalTrials.gov Identifier: NCT02495714 ) as of June 20 th - 2015, retrospectively registered. The collection of baseline values was initiated in mid-January 2015.

Wignjosoebroto, Sritomo

2007-12-01

There are so many definitions for ergonomics terms such as human factors, human factors engineering, human engineering, human factors psychology, engineering psychology, applied ergonomics, occupational ergonomics, industrial ergonomics and industrial engineering. The most inclusive terms are ergonomics and human factors. Both represent the study of work and the interaction between people and their work environmental systems. The main objective is especially fitting with the need to design, develop, implement and evaluate human-machine and environment systems that are productive, comfortable, safe and satisfying to use. The work of the ergonomists in Indonesia--most of them are academicians--have one thing in common, i.e. with the appropriate type of ergonomic approaches to interventions; there would be improvements in productivity, quality of working conditions, occupational safety and health (OSH), costs reduction, better environment, and increase in profits. So many researches, training, seminars and socialization about ergonomics and OSH have been done concerning micro-to-macro themes; but it seems that we are practically still running at the same place up to now. In facts, workers are still working using their traditional or obsolete methods in poor working conditions. Accidents are still happening inside and outside industry with the main root-cause being human "unsafe behavior" and errors. Industrial products cannot compete in the global market, and so many manufacturing industries collapsed or relocated to foreign countries. This paper discusses such a roadmap and review what we ergonomists in Indonesia have done and where we are going to? This review will be treated in the field of ergonomics and OSH to take care the future Indonesia challenges. Some of the challenges faced are care for the workers, care for the people, care for the quality and productivity of work, care for the new advanced technologies, care for the environment, and last but not least

The prevalence of mental disorders amongst children and adolescents is an increasing global problem. Schools have been positioned at the forefront of promoting positive mental health and well-being through implementing evidence-based interventions. The aim of this paper is to review current evidence-based research of mental health promotion interventions in schools and examine the reported effectiveness to identify those interventions that can support current policy and ensure that limited resources are appropriately used. The authors reviewed the current state of knowledge on school mental health promotion interventions globally. Two major databases, SCOPUS and ERIC were utilised to capture the social science, health, arts and humanities, and education literature. Initial searches identified 25 articles reporting on mental health promotion interventions in schools. When mapped against the inclusion and exclusion criteria, 10 studies were included and explored. Three of these were qualitative and seven were quantitative. A range of interventions have been tested for mental health promotion in schools in the last decade with variable degrees of success. Our review demonstrates that there is still a need for a stronger and broader evidence base in the field of mental health promotion, which should focus on both universal work and targeted approaches to fully address mental health in our young populations.

Discussion after implementation of possible ergonomics contributions in production lines automation project

José Adriano Canton

2016-11-01

Full Text Available This paper addresses the issue of work spaces designed based on Activity-Centered Ergonomics. The aim was to reflect on the role of Ergonomics in the design of productive situations in order to anticipate and mitigate the emergence of new constraints. This study was developed using a case study from the packaging industry, where an automated line was implemented to mitigate the injuries suffered as result of the manual system. This article was based on the results of an Ergonomic Work Analysis of the solution implemented, and the subsequent analysis of this design process. It was found that the adopted solution does not have enough leeway for dealing with variations inherent to the process, requiring constant interventions in the operation, by the operators in order to free the line to continue work. It was evident that the adopted solution did not involve the participation of important agents such as the operators and the maintenance crew, giving the project a technical vision that was concerned with eliminating the human factor. The conclusion of this study was that the Ergonomics integrated into the project development favors the collective construction of analysis of the research, and consequently, the development of more effective solutions.

Incorporating organisational safety culture within ergonomics practice.

Bentley, Tim; Tappin, David

2010-10-01

This paper conceptualises organisational safety culture and considers its relevance to ergonomics practice. Issues discussed in the paper include the modest contribution that ergonomists and ergonomics as a discipline have made to this burgeoning field of study and the significance of safety culture to a systems approach. The relevance of safety culture to ergonomics work with regard to the analysis, design, implementation and evaluation process, and implications for participatory ergonomics approaches, are also discussed. A potential user-friendly, qualitative approach to assessing safety culture as part of ergonomics work is presented, based on a recently published conceptual framework that recognises the dynamic and multi-dimensional nature of safety culture. The paper concludes by considering the use of such an approach, where an understanding of different aspects of safety culture within an organisation is seen as important to the success of ergonomics projects. STATEMENT OF RELEVANCE: The relevance of safety culture to ergonomics practice is a key focus of this paper, including its relationship with the systems approach, participatory ergonomics and the ergonomics analysis, design, implementation and evaluation process. An approach to assessing safety culture as part of ergonomics work is presented.

Does drywall installers' innovative idea reduce the ergonomic exposures of ceiling installation: A field case study.

The study was conducted to assess an intervention suggested by the workers to reduce the physical or ergonomic exposures of the drywall installation task. The drywall installers were asked to brainstorm on innovative ideas that could reduce their ergonomic exposures during the drywall installation work. The workers proposed the idea of using a 'deadman' (narrow panel piece) to hold the panels to the ceiling while installing them. The researcher collected quantitative exposure data (PATH, 3DSSPP) at the baseline and intervention phases and compared the phases to find out any change in the exposure while using the 'deadman'. Results showed that ergonomic exposures (such as overhead arm and awkward trunk postures and heavy load handling) were reduced at the intervention phase while using the 'deadman' with an electrically operated lift. The concept of the 'deadman', which was shown to help reduce musculoskeletal exposures during ceiling installation, can be used to fabricate a permanent ergonomic tool to support the ceiling drywall panel.

Research investigating the effectiveness of universal interventions to reduce the risk of mental health problems remains limited. Schools are a promising setting within which adolescents can receive interventions aimed at promoting their mental health. The aim of this study is to assess the effectiveness of a resilience-based prevention-focused intervention in reducing the risk of mental health problems among adolescents attending secondary school in socio-economically disadvantaged areas. A cluster randomised control trial will be conducted, with schools as the unit of randomisation. Initially, 32 secondary schools will be randomly allocated to a control or intervention group (12 control and 20 intervention). An intervention focused on improving student internal and external resilience factors will be implemented in intervention schools. A survey of students in Grade 7 in both intervention and control schools will be conducted (baseline) and repeated three years later when the students are in Grade 10. The Strengths and Difficulties Questionnaire will be used to measure the risk of mental health problems. At follow-up, the risk of mental health problems will be compared between Grade 10 students in intervention and control schools to determine intervention effectiveness. The study presents an opportunity to determine the effectiveness of a comprehensive resilience-based intervention in reducing the risk of mental health problems in adolescents attending secondary schools. The outcomes of the trial are of importance to youth, schools, mental health clinicians and policymakers.

Full Text Available It is indicated that children are involuntarily exposed to secondhand smoke from adults, mainly at their home environment. This study aimed at describing the effectiveness of the school-based intervention to decrease the in-home smoking situation of adults so as to decrease children’s exposure to secondhand smoke at home during the year 2011–2012 in a rural district in Hanoi, Viet Nam. This school-based intervention program (intervention and control group involved 804 children aged 8 to 11 years from August 2011 to May 2012 in a rural district of Hanoi, Viet Nam. Children were taught in class about the harmful effects of secondhand smoke and about how to negotiate with fathers not to smoke in-home. Then children applied what they learnt, including staying away from secondhand smoke and persuading fathers not to smoke in-home in order to decrease children’s exposure to secondhand smoke. Chi square test, t-test and multinominal logistic regression were applied in data analysis. The results showed that children’s reported their father’s in-home smoking decreased from 83.0% pre-intervention to 59.8% post-intervention (p < 0.001 in the intervention school while no change happened in the control school. The study found that the better changed smoking location of adult smokers as reported by children associated with the school who received intervention activities (adjusted OR = 2.04; 95% CI: 1.28–3.24. Poorer changed attitudes towards secondhand smoke of children associated with a lower percentage of better change in smoking location of their fathers/other adult smokers (aOR = 0.51, 95% CI: 0.28–0.96. Children’s poorer changed knowledge towards secondhand smoke also associated with poorer changed smoking location of adult smokers (aOR = 2.88, 95% CI: 1.07–7.76. It is recommended by this study that similar school based intervention approaches should be applied in primary schools in Viet Nam to increase children’s awareness on the

Full Text Available Obesity in childhood is increasing worldwide. To combat overweight and obesity in childhood, the school-based Children's Health InterventionaL Trial (CHILT project combines health education and physical activity. This paper examines the effect of intervention on the body mass index (BMI and motor abilities after 20.8 ± 1.0 months in 12 randomly selected primary schools compared with 5 randomly selected control schools. The anthropometric data were assessed, BMI was calculated. Coordination was determined by lateral jumping and endurance performance by a 6-minute run. No difference in the prevalence of overweight and obesity was found between the intervention (IS and control schools (CS either at baseline or following intervention (each p > 0.05. The increase in the number of lateral jumps was significantly higher in the IS than in the CS (p < 0.001. For the 6-minute run the increase in distance run was significantly improved in IS (p = 0.020. All variables were controlled for gender and age. Overweight and obese children in both IS and CS produced significantly lower scores in coordination and endurance tasks than normal and underweight children during both examinations (each p < 0.001, adjusted for gender and age. Preventive intervention in primary schools offers an effective means to improve motor skills in childhood and to break through the vicious circle of physical inactivity - motor deficits - frustration - increasing inactivity possibly combined with an excess energy intake and weight gain. To prevent overweight and obesity these measures have to be intensified

This study followed children with Autism Spectrum Disorder (ASD) from early intervention into their early schooling years, when they were aged between 6 and 9 years, on autism symptom severity and cognitive functioning. The children, matched at pre-intervention, were compared on type of community provided service: 31 were in receipt of community-based group Early Start Denver Model and 28 had received other community provisions for ASD. Irrespective of groups, cognitive functioning was found to have significantly improved by school age compared to pre-intervention. Autism symptom severity increased during the same developmental period, seemingly driven by an increase in restricted and repetitive behaviours over time. In contrast, both groups displayed improved social affect by school age.

Children in Sub-Saharan Africa (SSA) are burdened by significant unmet mental health needs, but this region has limited access to mental health workers and resources to address these needs. Despite the successes of numerous school-based interventions for promoting child mental health, most evidence-based interventions are not available in SSA. This study will investigate the transportability of an evidence-based program from a developed country (United States) to a SSA country (Uganda). The approach includes task-shifting to early childhood teachers and consists of professional development (five days) to introduce strategies for effective behavior management and positive teacher-student interactions, and group-based consultation (14 sessions) to support adoption of effective practices and tailoring to meet the needs of individual students. The design of this study is guided by two implementation frameworks, the Consolidated Framework for Implementation Research and the Teacher Training Implementation Model, that consider multidimensional aspects of intervention fidelity and contextual predictors that may influence implementation and teacher outcomes. Using a cluster randomized design, 10 schools in Uganda will be randomized to either the intervention group (five schools) or the waitlist control group (five schools). A total of 80 to 100 early childhood teachers will be enrolled in the study. Teacher utilization of evidence-based strategies and practices will be assessed at baseline, immediate post-intervention (six months after baseline), and at seven months post-intervention (during a new academic year). Fidelity measures will be assessed throughout the program implementation period (during professional development and consultation sessions). Individual teacher and contextual factors will be assessed at baseline. Data will be collected from multiple sources. Linear mixed-effect modeling, adjusting for school nesting, will be applied to address study questions. The

A cluster-randomized controlled-trial examining the effect of a school-based comprehensive intervention on nutrition knowledge, eating habits, and behaviors among low socioeconomic status (LSES school-aged children was performed. LSES school-aged children (4–7 years and their mothers were recruited from 11 schools, located in one town. The intervention was implemented on three levels: children, mothers, and teachers. The intervention (IArm included nutrition classes for children, mothers, and teachers and physical activity (PA classes for children; the control (CArm received PA only. Interventions were conducted by professional personnel, who were trained during in a two-day session to deliver the specific program in schools. Family data were obtained by parental interviews. Food knowledge observations, packed lunch records, and anthropometric measurements were obtained in school at baseline, six months, and at the end of the school year. Of 258 children enrolled, 220 (87.6% completed the six-month program. Only children in the IArm improved their nutrition knowledge and eating-habits and increased food variety and fruit and vegetable consumption, quality score of packed lunches (p < 0.001 for all, habitual water drinking increased (p = 0.02, and decreased sweet-drink consumption (p = 0.05. A school-based comprehensive nutrition intervention targeting LSES population improved eating habits, nutritional knowledge, and healthier packed lunches.

Full Text Available Mindfulness programs for schools are popular. We systematically reviewed the evidence regarding the effects of school-based mindfulness interventions on psychological outcomes, using a comprehensive search strategy designed to locate both published and unpublished studies. Systematic searches in 12 databases were performed in August 2012. Further studies were identified via hand search and contact with experts. Two reviewers independently extracted the data, also selecting information about intervention programs (elements, structure etc., feasibility, and acceptance. Twenty-four studies were identified, of which 13 were published. Nineteen studies used a controlled design. In total, 1,348 students were instructed in mindfulness, with 876 serving as controls, ranging from grade 1 to 12. Overall effect sizes were Hedge's g = 0.40 between groups and g = 0.41 within groups (p < 0.0001. Between group effect sizes for domains were: cognitive performance g = 0.80, stress g = 0.39, resilience g = 0.36, (all p < 0.05, emotional problems g = 0.19 third person ratings g = 0.25 (both n.s.. All in all, mindfulness-based interventions in children and youths hold promise, particularly in relation to improving cognitive performance and resilience to stress. However, the diversity of study samples, variety in implementation and exercises, and wide range of instruments used require a careful and differentiated examination of data. There is great heterogeneity, many studies are underpowered, and measuring effects of Mindfulness in this setting is challenging. The field is nascent and recommendations will be provided as to how interventions and research of these interventions may proceed.

Hygiene education appears to be the commonest school-based intervention for preventing infectious diseases, especially in the developing world. Nevertheless, there remains a gap in literature regarding a school-specific theory-based framework for designing a hand hygiene educational intervention in schools. We sought to suggest a framework underpinned by psychosocial theories towards bridging this knowledge gap. Furthermore, we sought to propound a more comprehensive definition of hand hygiene which could guide the conceptualisation of hand hygiene interventions in varied settings. Literature search was guided by a standardized tool and literature was retrieved on the basis of a predetermined inclusion criteria. Databases consulted include PubMed, ERIC, and EBSCO host (Medline, CINAHL, PsycINFO, etc.). Evidence bordering on a theoretical framework to aid the design of school-based hand hygiene educational interventions is summarized narratively. School-based hand hygiene educational interventions seeking to positively influence behavioural outcomes could consider enhancing psychosocial variables including behavioural capacity, attitudes and subjective norms (normative beliefs and motivation to comply). A framework underpinned by formalized psychosocial theories has relevance and could enhance the design of hand hygiene educational interventions, especially in schools.

This study aims to examine the effect of school-based preventive intervention on cannabis use in Czech adolescents with different levels of risk factors and provide evidence of its universality. A randomized controlled prevention trial with six waves was conducted over a period of 33 months. We used a two-level logistic random-intercept model for panel data; we first looked at the statistical significance of the effect of the intervention on cannabis use, controlling for the characteristics of the children and time dummies. Then we analyzed the effects of the interactions between the intervention and the characteristics of the children on cannabis use and related it to the definition of universal preventive interventions. The setting for the study was in basic schools in the Czech Republic in the years 2007-2010. A total of 1,874 sixth-graders (mean age 11.82 years) who completed the baseline testing. According to our results, the prevention intervention was effective. We found all the selected characteristics of the children to be relevant in relation to cannabis use, except their relationships with their friends. We showed empirically that the intervention is universal in two dimensions for the selected characteristics of the children. First, all adolescents who undergo the intervention are expected to benefit. Second, with respect to the effect of the intervention on cannabis use, the total level of individual risk of cannabis use is superior to the composition of the risk factors in the individual risk profile. We present indicative evidence that the drug prevention intervention may be considered a true universal preventive intervention.

Work-related musculoskeletal disorders (WMSD) represent a major public health problem and economic burden to employers, workers and health insurance systems. This systematic review had two objectives: (1) to analyze the cost-benefit results of organizational-level ergonomic workplace-based interventions aimed at preventing WMSD, (2) to explore factors related to the implementation process of these interventions (obstacles and facilitating factors) in order to identify whether economic results may be due to a successful or unsuccessful implementation. Systematic review. Studies were searched in eight electronic databases and in reference lists of included studies. Companion papers were identified through backward and forward citation tracking. A quality assessment tool was developed following guidelines available in the literature. An integration of quantitative economic results and qualitative implementation data was conducted following an explanatory sequential design. Out of 189 records, nine studies met selection criteria and were included in our review. Out of nine included studies, grouped into four types of interventions, seven yielded positive economic results, one produced a negative result and one mixed results (negative cost-effectiveness and positive net benefit). However, the level of evidence was limited for the four types of interventions given the quality and the limited number of studies identified. Our review shows that among the nine included studies, negative and mixed economic results were observed when the dose delivered and received by participants was low, when the support from top and/or middle management was limited either due to limited participation of supervisors in training sessions or a lack of financial resources and when adequacy of intervention to workers' needs was low. In studies where economic results were positive, implementation data showed strong support from supervisors and a high rate of employee participation. Studies

Home and school environments conducive for unhealthy eating and physical inactivity are precursors of obesity. The aim of this study is evaluation of the effectiveness of a multi-component school-based weight management programme for overweight and obese primary school children via a home-school joint venture. This study made use of variety of behavioural modification strategies integrating into the Health Promoting School approach to promote healthy lifestyles. The participants were overweight and obese students aged between 8 and 12 from six participating schools. The interventions involved students attending ten 75 minutes after-school sessions and one 3-hour week-end session of practical interactive and fun activities on healthy eating and exercise, and meal plan together with parents and printed tailor-made management advices. Parents received an introductory seminar with 2 sets of specially designed exercise for their overweight children. The tools to measure bodyweight and fat percentage and standing height were bio-impedance body fat scale and a portable stadiometer. Self-administered questionnaire was used to measure knowledge, attitudes and behaviours. McNemar test was utilized to compare the proportions of behaviour changes within the same group to assess for the trends of changes. BMI z-score and body fat percentage of intervention participants at baseline, 4 month and 8 month were compared pair-wisely using tests of within subject contrasts in repeated measures ANOVA to assess for programme sustainability. Those students in the intervention group reduced their BMI z-score (-0.21, 95% CI -0.34 to -0.07, P = 0.003) and body fat (-2.67%, 95% CI -5.12 to -0.22, P = 0.033) compared to wait list control group with statistical significant, and the intervention group also had a significant reduction in BMI z-score (-0.06, 95% CI -0.11, -0.007, P = 0.028) and body fat (-1.71%, 95% CI, -3.44 to 0.02, P = 0.052) after a 4 month maintenance period.

Full program implementation is crucial for effectiveness but is often overlooked or insufficiently considered during development of behavioral change interventions. For school-based health promotion programs, teachers are key players in program implementation, but teacher support in this phase is mostly limited to technical support and information. To ensure optimal implementation of the Dutch school-based sexual health program Long Live Love, a Web-based coaching website was developed to support teachers in completeness and fidelity of program implementation. The aim of this paper is to provide insight into the process of systematic development of a Web-based coaching intervention to support teachers in their implementation of a school-based sexual health program. The intervention mapping (IM) protocol was applied for the development of a theory- and evidence-based intervention. The IM process begins with (1) a needs assessment, followed by (2) the formulation of change objectives, (3) the selection of theory-based intervention methods and practical applications that take the parameters for effectiveness into consideration, (4) integration of practical applications into an organized program, (5) planning for adoption, implementation, and sustainability of the program, and finally, (6) generating an evaluation plan to measure program effectiveness. Teacher's implementation behavior was characterized by inconsistently selecting parts of the program and not delivering (all) lessons as intended by program developers. Teachers, however, did not perceive this behavior as problematic, revealing the discrepancy between teacher's actual and perceived need for support in delivering Long Live Love lessons with completeness and fidelity. Teachers did, however, acknowledge different difficulties they encountered which could potentially negatively influence the quality of implementation. With the IM protocol, this Web-based coaching intervention was developed based on a concept

Full Text Available Abstract Background Although several previous projects have attempted to address the issue of child obesity through school-based interventions, the overall effectiveness of school-based programs on health-related outcomes in youth has been poor. Thus, it has been suggested that multi-level interventions that aim to influence healthy lifestyle behaviors at the community, school and family levels may prove more successful in the prevention of childhood obesity. Methods/Design This paper describes the rationale, design, and implementation of a community-, school-, and family-based intervention aimed at modifying key behaviors (physical activity, screen time (Internet, television, video games, and nutrition related to childhood obesity among third through fifth graders in two mid-western cities. The intervention involves a randomized study of 10 schools (5 intervention and 5 control schools. The intervention is being conducted during the duration of the academic year – approximately 9 months – and includes baseline and post-intervention measurements of physical activity, dietary intake, screen time and body composition. Discussion We hope this report will be useful to researchers, public health professionals, and school administrators and health professionals (nurses and physical/health educators seeking to develop similar prevention programs. It is obvious that more collaborative, inter-disciplinary, multi-level work is needed before a proven, effective intervention package to modify behaviors related to childhood obesity can be generally recommended. It is our hope that SWITCH is a step in that direction. Trial Registration ClinicalTrials.gov NCT00685555

Full Text Available Background and Aims: There are several risk factors in dentistry professional environment. Carelessness about occupational health regulation endangers dentist's life. Erconomics in dentistry is a scientific approach which introduces the latest ergonomic principles in dental profession. It discusses about physical and mental stresses. Ergonomic programs eliminate dentist physical and mental challenges and provide practical solution to establish efficient and comforting environment. Materials and Methods: This study reviewed the role and effectiveness of Ergonomics in dental profession. We used related journals, books and ergonomics websites to write this article. Conclusion: Many of researchers believe that awkward body posture and low movement are the sources of occupational disorders. Therefore, knowledge of ergonomics risk factors in dental office design is very important. Dentist's body posture and dental equipment evaluations are important factors in dental ergonomics. The most logical approach to design dental equipment for utilizing ergonomics principles is consideration of the dentist posture and type of movements and activities. In conclusion, dentists should be informed about dental ergonomics regulation and its different aspects. Furthermore, academic developments and research projects can be useful in this area.

Ergonomics interventions have the potential to improve operational performance and employee well-being. We introduce a framework for ergonomics climate, the extent to which an organization emphasizes and supports the design and modification of work to maximize both performance and well-being outcomes. We assessed ergonomics climate at a large manufacturing facility twice during a two-year period. When the organization used ergonomics to promote performance and well-being equally, and at a high level, employees reported less work-related pain. A larger discrepancy between measures of operational performance and employee well-being was associated with increased reports of work-related pain. The direction of this discrepancy was not significantly related to work-related pain, such that it didn't matter which facet was valued more. The Ergonomics Climate Assessment can provide companies with a baseline assessment of the overall value placed on ergonomics and help prioritize areas for improving operational performance and employee well-being.

This article discusses the implementation of ergonomics in a service unit of a major company in the energy sector. From the perspective of management, it analyses the process of implementation of ergonomics programmes in four operational areas. The objective was to diagnose the level of implementation of ergonomics. The study is descriptive, undertaken through the interaction with the technical staff of the operational areas involved, incorporating the perception of these role players concerning their work routines. The results indicated significant differences in the level of implementation of the programmes, especially those concerning structural conditions. Important conquests were registered, such as the investment in the training of specialists, the establishment of a facilitator network and the improvement of the standard for the directioning and alignment of the execution of initiatives. The linking in of the programmes with those of occupational health management emphasises its contribution to the safety and well-being of the workforce through interventions aimed mainly at eliminating and reducing ergonomic biomechanical risks. However, the need to broaden and deepen the ergonomic approach regarding organizational and cognitive aspects, as well as the insertion of ergonomics in project design of new work spaces and processes were also identified.

Suicide in young people is a significant health concern, with numerous community- and school-based interventions promising to prevent suicide currently being applied across Canada. Before widespread application of any one of these, it is essential to determine its effectiveness and safety. We systematically reviewed the global literature on one of the most common community suicide prevention interventions in Canada and summarized data on 2 commonly applied school-based suicide prevention programmes. None of these has demonstrated effectiveness in preventing youth suicide or safety in application. Concurrently with their widespread distribution in Canada, the suicide rate in young women has increased-the first time in over 3 decades. Policy and regulatory implications of these findings are discussed.

Full Text Available Abstract Background Both low back pain (LBP and neck pain (NP are major occupational health problems. In the workplace, participatory ergonomics (PE is frequently used on musculoskeletal disorders. However, evidence on the effectiveness of PE to prevent LBP and NP obtained from randomised controlled trials (RCTs is scarce. This study evaluates the process of the Stay@Work participatory ergonomics programme, including the perceived implementation of the prioritised ergonomic measures. Methods This cluster-RCT was conducted at the departments of four Dutch companies (a railway transportation company, an airline company, a steel company, and a university including its university medical hospital. Directly after the randomisation outcome, intervention departments formed a working group that followed the steps of PE during a six-hour working group meeting. Guided by an ergonomist, working groups identified and prioritised risk factors for LBP and NP, and composed and prioritised ergonomic measures. Within three months after the meeting, working groups had to implement the prioritised ergonomic measures at their department. Data on various process components (recruitment, reach, fidelity, satisfaction, and implementation components, i.e., dose delivered and dose received were collected and analysed on two levels: department (i.e., working group members from intervention departments and participant (i.e., workers from intervention departments. Results A total of 19 intervention departments (n = 10 with mental workloads, n = 1 with a light physical workload, n = 4 departments with physical and mental workloads, and n = 4 with heavy physical workloads were recruited for participation, and the reach among working group members who participated was high (87%. Fidelity and satisfaction towards the PE programme rated by the working group members was good (7.3 or higher. The same was found for the Stay@Work ergocoach training (7.5 or higher. In total, 66

Purpose Although safe Internet use is an emerging public health issue, there is a scarcity of published work describing relevant school-based interventions. The objective of this study was to explore the impact of a health professional-led, school-based intervention in raising awareness on cyber-safety in adolescents, Therefore, the aim of this study was to investigate adolescents' evaluation of this school-based intervention, 6 months after its implementation, as well as the impact of adolescents' school class and gender on their evaluation. Methods A student sample was selected using a multistage stratified random sampling technique, according to the location and school grade level (middle, high school). The students - aged from 12 to 18 years old experienced an interactive presentation in their classrooms on the amount of time spent online, the use of social networks and the available support services. An evaluation tool was completed anonymously and voluntarily 6 months after the intervention. Results Four hundred and sixty-two students (response rate 90.7%, 246 middle, 216 high school) completed the evaluation tool. Younger students, especially the ones in the first year of middle school, scored significantly higher in all six parameters used in the evaluation of this intervention compared with all the older participants: (a) they had kept the presented information on Safeline and Saferinternet websites and the helpline Ypostirizo (70.2% vs. 33.7%, p < 0.001) (b) they had already used it (32.5% vs. 12.3%, p < 0.001), (c) they had learned new information on cyber safety (66.4% vs. 34%, p < 0.001), (d) they rated the intervention as more interesting (median 8 vs. 7, p < 0.05), (e) they had reconsidered the way they use Internet (median 7 vs. 6, p < 0.05) and (f) they had changed their cyber behavior (median 7 vs. 5, p < 0.05). Conclusion The active involvement of students in a discussion on cyber-safety based on their experiences was highly evaluated. The impact

Regular participation in moderate-to-vigorous physical activity (MVPA) is important to manage obesity. Physical education (PE) is considered to play an important role in promoting lifelong participation in physical activity (PA) because it provides an existing network where cost-effective interventions can be implemented to produce sustainable change in health behavior. However, the association between compulsory school PA (e.g., PE lessons) and body composition levels has received mixed support in the literature. Therefore, the present study aimed to investigate whether a school-based intervention targeting salient PA benefits and barriers grounded on the theory of planned behavior would promote young people's participation in MVPA during leisure time and reduce body mass index (BMI) of overweight students. A total of 171 students from 3 secondary schools in Singapore underwent the control condition followed by the intervention condition. Both the conditions consisted of PE lessons twice per week over 4 weeks. In the control condition, PE teachers encouraged students to participate in PA during leisure time without providing persuasive message. While in the intervention condition, PE teachers delivered persuasive messages that targeted the salient benefits and barriers associated with PA to the students at the last 5 to 10 min of each PE lesson. PA levels over a week were measured objectively with wrist-mounted GENEActiv Original accelerometers and subjectively with self-reporting questionnaires three times (Baseline, Post 1, and Post 2) in each condition. Student's self-reported PA level was measured using the Leisure-Time Physical Activity Participation Questionnaire and the International Physical Activity Questionnaire, and their attitudes, intentions, subjective norms and perceived behavior control towards leisure-time PA were measured with a questionnaire based on the theory of planned behavior. Furthermore, students' intention, determination and

The stages of change (Precontemplation, Contemplation, Preparation, Action, and Maintenance) have been well studied in adult populations. However, fewer studies have examined how the stages of change are related to adolescent substance use. Furthermore, there have been no studies that have examined how the stages of change relate to outcomes in a school-based intervention. To better capture adolescent motivation, we added an additional group to the Transtheoretical Model of Change, which we titled Coerced Action, to represent adolescents that made changes to their substance use despite low problem recognition (representing the internal motivation of Precontemplation and the change behaviors of the Action group). We then examined how the stages of change were related to a thorough assessment of substance use at baseline and corresponding treatment outcomes. Our sample consisted of 264 adolescents (mean age: 16.1, 44.5% Caucasian, 37.5% female) who participated in an 8-week, school-based Motivational Enhancement intervention. Results indicated significant group differences across the stages of change in substance use patterns (alcohol use, negative consequences, affective dysregulation), as well as treatment outcomes (alcohol use and negative consequences). For instance, adolescents in the Action group demonstrated more negative consequences at 16weeks follow-up than those in Precontemplation and Coerced Action, F(1, 3)=8.23, pmotivation among adolescent substance users within school-based settings.

Effects of school-based interventions on mental health stigmatization: a systematic review

Directory of Open Access Journals (Sweden)

Lacroix Denise

2008-07-01

Full Text Available Abstract Stigmatizing, or discriminatory, perspectives and behaviour, which target individuals on the basis of their mental health, are observed in even the youngest school children. We conducted a systematic review of the published and unpublished, scientific literature concerning the benefits and harms of school-based interventions, which were directed at students 18 years of age or younger to prevent or eliminate such stigmatization. Forty relevant studies were identified, yet only a qualitative synthesis was deemed appropriate. Five limitations within the evidence base constituted barriers to drawing conclusive inferences about the effectiveness and harms of school-based interventions: poor reporting quality, a dearth of randomized controlled trial evidence, poor methods quality for all research designs, considerable clinical heterogeneity, and inconsistent or null results. Nevertheless, certain suggestive evidence derived both from within and beyond our evidence base has allowed us to recommend the development, implementation and evaluation of a curriculum, which fosters the development of empathy and, in turn, an orientation toward social inclusion and inclusiveness. These effects may be achieved largely by bringing especially but not exclusively the youngest children into direct, structured contact with an infant, and likely only the oldest children and youth into direct contact with individuals experiencing mental health difficulties. The possible value of using educational activities, materials and contents to enhance hypothesized benefits accruing to direct contact also requires investigation. Overall, the curriculum might serve as primary prevention for some students and as secondary prevention for others.

Fisher, Paige H; Masia-Warner, Carrie; Klein, Rachel G

2004-12-01

This paper describes Skills for Academic and Social Success (SASS), a cognitive-behavioral, school-based intervention for adolescents with social anxiety disorder. Clinic-based treatment studies for socially anxious youth are reviewed, and a strong rationale for transporting empirically-based interventions into schools, such as SASS, is provided. The SASS program consists of 12, 40-min group sessions that emphasize social skills and in-vivo exposure. In addition to group sessions, students are seen individually at least twice and participate in 4 weekend social events with prosocial peers from their high schools. Meetings with teachers provide information about social anxiety and facilitate classroom exposures for socially anxious participants. Parents attend 2 psychoeducational meetings about social anxiety, its treatment, and approaches for managing their child's anxiety. Initial findings regarding the program's effectiveness are presented. We conclude by discussing the challenges involved in implementing treatment protocols in schools and provide suggestions to address these issues.

An important aspect that affects the effectiveness of ergonomic programs is that inefficient mechanical functioning start at an early age and that back pain and posture problems are already evident in children. Children, from a very early age, as well as adults spend an ever increasing amount of their time in front of computer and television screens. The cumulative effect of this sedentary lifestyle leads to improper posture, as well as inefficient and harmful movement patterns and loss of basic physical skills. Physical Education course should deal not only with sports and physical activities, but also with broader aspects of life-skills and physical functionality. It should offer a solution to the modern technology-based society. Keeping this in perspective, Ergonomics content was introduced in Physical Education Teacher's Guide in Rwandan schools with an aim in preventing musculoskeletal disorder in children.

To assess the impact of a school-based menstrual education programme on: (1) menstrual knowledge, beliefs and practices, (2) menstrual disorders experienced, and (3) restrictions on menstruating adolescents. Intervention study. Araihazar area, Bangladesh. 416 adolescent female students aged 11-16 years, in grade 6-8, and living with their parents. A school-based health education study conducted from April 2012 to April 2013. We randomly selected 3 of 26 high schools in the study area. We delivered 6 months of educational intervention by trained (by an obstetrician and gynaecologist) research assistants (RAs) on menstrual hygiene among school girls. RAs read the questionnaire and participants answered. The changes in knowledge, beliefs and practices regarding menstruation, menstrual disorders experienced, and the restrictions and behaviours practiced by menstruating adolescents were compared between the baseline and the follow-up assessments. After health education, participants reported a significant improvement (pmenstruation (78.6% vs 59.6%). The programme produced significant changes in the knowledge, beliefs and practices of menstrual hygiene, complications from lack of hygiene, and the behaviour and restrictions of the menstruating adolescents. These results demonstrate the feasibility of implementing a health education programme for adolescents on menstrual hygiene in secondary schools serving rural Bangladesh.

To conduct a process evaluation of the implementation of an ergonomics training program aimed at increasing the use of loading assist devices in flight baggage handling. Feasibility related to the process items recruitment, reach, context, dose delivered (training time and content); dose received (participants' engagement); satisfaction with training; intermediate outcomes (skills, confidence and behaviors); and barriers and facilitators of the training intervention were assessed by qualitative and quantitative methods. Implementation proved successful regarding dose delivered, dose received and satisfaction. Confidence among participants in the training program in using and talking about devices, observed use of devices among colleagues, and internal feedback on work behavior increased significantly (pjob insecurity. In identifying important barriers and facilitators for a successful outcome, this study can help supporting the effectiveness of future interventions. Our results suggest that barriers caused by organizational changes may likely be alleviated by recruiting motivated trainees and securing strong organizational support for the implementation.

To gain insight into the process of applying two guidance strategies - face-to-face (F2F) or e-guidance strategy (EC) - of a Participatory Ergonomics (PE) intervention and whether differences between these guidance strategies occur, 12 construction companies were randomly assigned to a strategy. The process evaluation contained reach, dose delivered, dose received, precision, competence, satisfaction and behavioural change of individual workers. Data were assessed by logbooks, and questionnaires and interviews at baseline and/or after six months. Reach was low (1%). Dose delivered (F2F: 63%; EC: 44%), received (F2F: 42%; EC: 16%) were not sufficient. The precision and competence were sufficient for both strategies and satisfaction was strongly affected by dose received. For behavioural change, knowledge (F2F) and culture (EC) changed positively within companies. Neither strategy was delivered as intended. Compliance to the intervention was low, especially for EC. Starting with a face-to-face meeting might lead to higher compliance, especially in the EC group. Practitioner Summary: This study showed that compliance to a face-to-face and an e-guidance strategy is low. To improve the compliance, it is advised to start with a face-to-face meeting to see which parts of the intervention are needed and which guidance strategy can be used for these parts.

In the 1980's, the visual display terminal (VDT) was introduced in workplaces of many countries. Soon thereafter, an upsurge in reported cases of related health problems, such as musculoskeletal disorders and eyestrain, was seen. Recently, the flat panel display or notebook personal computer (PC) became the most remarkable feature in modern workplaces with VDTs and even in homes. A proactive approach must be taken to avert foreseeable ergonomic and occupational health problems from the use of this new technology. Because of its distinct physical and optical characteristics, the ergonomic requirements for notebook PCs in terms of machine layout, workstation design, lighting conditions, among others, should be different from the CRT-based computers. The Japan Ergonomics Society (JES) technical committee came up with a set of guidelines for notebook PC use following exploratory discussions that dwelt on its ergonomic aspects. To keep in stride with this development, the Technical Committee on Human-Computer Interaction under the auspices of the International Ergonomics Association worked towards the international issuance of the guidelines. This paper unveils the result of this collaborative effort.

The practice of office-based surgery is increasing in many specialties. Using Mohs surgery as a model, we investigated the role of ergonomics in office-based surgery to limit work-related musculoskeletal disorders. All Mayo Clinic surgeons currently performing Mohs surgery and Mohs surgeons trained at Mayo Clinic between 1990 and 2004 received a questionnaire survey between May 2003 and September 2004. A sample of respondents were videotaped during surgery. The main outcome measures were survey responses and an ergonomist's identification of potential causes of musculoskeletal disorders. All 17 surgeons surveyed responded. Those surveyed spend a mean of 24 hours per week in surgery. Sixteen said they had symptoms caused by or made worse by performing surgery. Symptom onset occurred on average at age 35.4 years. The most common complaints were pain and stiffness in the neck, shoulders, and lower back and headaches. Videotapes of 6 surgeons revealed problems with operating room setup, awkward posture, forceful exertion, poor positioning, lighting, and duration of procedures. Symptoms of musculoskeletal injuries are common and may begin early in a physician's career. Modifying footwear, flooring, table height, operating position, lighting, and surgical instruments may improve the ergonomics of office-based surgery.

This article discusses the quality of internal life space in apartments of residential buildings in the northeast region of Brazil, especially the possibility to adapt environments with small areas (according to local building codes) to the needs of different arrangements of families (considering 4 members per family). The research had a gradual approach and used multimethod strategy: (a) studying the universe of residential buildings whose apartment's inner area is between 50 and 60 m2 and were constructed in Natal-RN between 1998 and 2008, as well as not linked to social housing programs and occupied for more than one year; (b) selecting a building to do a Post Occupation Evaluation (POE), using walkthrough, technical observation and questionnaires; (c) choosing of two housing units to do an ergonomic intervention (based in interviews and detailed measurements). The results show the technical possibility to modify the units, but these modifications have a high (social, economic and environmental) price, because in general the space of units projected is not flexible. So, the paper concludes that this type of enterprise needs to be rethought, since part of them is (social and ecologically) unsustainable.

Participatory ergonomics (PE) can promote the application of human factors and ergonomics (HFE) principles to healthcare system redesign. This study applied a PE approach to redesigning the family-centred rounds (FCR) process to improve family engagement. Various FCR stakeholders (e.g. patients and families, physicians, nurses, hospital management) were involved in different stages of the PE process. HFE principles were integrated in both the content (e.g. shared mental model, usability, workload consideration, systems approach) and process (e.g. top management commitment, stakeholder participation, communication and feedback, learning and training, project management) of FCR redesign. We describe activities of the PE process (e.g. formation and meetings of the redesign team, data collection activities, intervention development, intervention implementation) and present data on PE process evaluation. To demonstrate the value of PE-based FCR redesign, future research should document its impact on FCR process measures (e.g. family engagement, round efficiency) and patient outcome measures (e.g. patient satisfaction).

With growing evidence for the positive health outcomes associated with a plant-based diet, the study's purpose was to examine the potential of shifting adolescents' food choices towards plant-based foods. Using a real world setting of a school canteen, a set of small changes to the choice architecture was designed and deployed in a secondary school in Yorkshire, England. Focussing on designated food items (whole fruit, fruit salad, vegetarian daily specials, and sandwiches containing salad) the changes were implemented for six weeks. Data collected on students' food choice (218,796 transactions) enabled students' (980 students) selections to be examined. Students' food choice was compared for three periods: baseline (29 weeks); intervention (six weeks); and post-intervention (three weeks). Selection of designated food items significantly increased during the intervention and post-intervention periods, compared to baseline (baseline, 1.4%; intervention 3.0%; post-intervention, 2.2%) χ(2)(2) = 68.1, p food items during the intervention period, compared to baseline. The study's results point to the influence of choice architecture within secondary school settings, and its potential role in improving adolescents' daily food choices.

Musculoskeletal disorders (MSDs) result in lost-time injury claims and lost productivity worldwide, placing a substantial burden on workers and workplaces. Participatory ergonomics (PE) is a popular approach to reducing MSDs; however, there are challenges to implementing PE programmes. Using evidence to overcome challenges may be helpful but the impacts of doing so are unknown. We sought to disseminate an evidence-based PE tool and to describe its use. An easy-to-use, evidence-based PE Guide was disseminated to workplace parties, who were surveyed about using the tool. The greatest barrier to using the tool was a lack of time. Reported tool use included for training purposes, sharing and integrating the tool into existing programmes. New actions related to tool use included training, defining team responsibilities and suggesting programme implementation steps. Evidence-based tools could help ergonomists overcome some challenges involved in implementing injury reduction programmes such as PE. Practitioner Summary Practitioners experience challenges implementing programmes to reduce the burden of MSDs in workplaces. Implementing participatory interventions requires multiple workplace parties to be 'on-board'. Disseminating and using evidence-based guides may help to overcome these challenges. Using evidence-based tools may help ergonomics practitioners implement PE programmes.

The concept of contradiction in ergonomics practice.

Nathanael, Dimitris; Zarboutis, Nikos; Marmaras, Nicolas

2012-01-01

The present communication deals with the methodology of the ergonomics field intervention process. It proposes an operationalized version of work analysis in terms of contradictions. The aim is to demonstrate that such a dialectic tool and method of representation may assist the ergonomist to frame the essence of a work activity in practical terms, swiftly and in a manner that preserves its multifaceted unity. The proposed method is inspired by two theoretical constructs (i) contradiction as used in Cultural Historical Activity Theory and (ii) regulation, as developed and used by the francophone tradition of ergonomics of activity. Two brief examples of its use are presented and a discussion is made on further developments and possible pitfalls.

The social environment at schools is an important setting to promote educational attainment, and health and well-being of young people. However, within upper secondary education there is a need for evidence-based school intervention programmes. The Shaping the Social intervention is a comprehensive programme integrating social and educational activities to promote student well-being and reduce smoking and dropout in upper secondary vocational education. The evaluation design is reported here. The evaluation employed a non-randomised cluster controlled design, and schools were selected to either implement the intervention or continue with normal practice for comparison. In the baseline survey conducted 2011-2012, 2,329 students from four intervention schools and 3,371 students from six comparison schools answered a computer-based questionnaire during class, representing 73% and 81% of eligible students, and 22% of all technical/agricultural vocational schools in Denmark. Follow-up assessment was conducted 10 weeks after baseline and at the same time teachers of the intervention classes answered a questionnaire about implementation. School dropout rates will be tracked via national education registers through a 2-year follow-up period. Shaping the Social was designed to address that students at Danish vocational schools constitute a high risk population concerning health behaviour as well as school dropout by modifying the school environment, alongside developing appropriate evaluation strategies. To address difficulties in implementing settings-based interventions, as highlighted in prior research, the strategy was to involve intervention schools in the development of the intervention. Baseline differences will be included in the effectiveness analysis, so will the impact of likely mediators and moderators of the intervention. ISRCTN57822968. Date of registration: 16/01/2013.

To provide a framework for implementation of multicomponent, school-based nutrition interventions. This article describes the research methods for the Shaping Healthy Choices Program, a model to improve nutrition and health-related knowledge and behaviors among school-aged children. Longitudinal, pretest/posttest, randomized, controlled intervention. Four elementary schools in California. Fourth-grade students at intervention (n = 252) and control (n = 238) schools and their parents and teachers. Power analyses demonstrate that a minimum of 159 students per group will be needed to achieve sufficient power. The sample size was determined using the variables of nutrition knowledge, vegetable preference score, and body mass index percentile. A multicomponent school-based nutrition education intervention over 1 academic year, followed by activities to support sustainability of the program. Dietary and nutrition knowledge and behavior, critical thinking skills, healthy food preferences and consumption, and physical activity will be measured using a nutrition knowledge questionnaire, a food frequency questionnaire, a vegetable preferences assessment tool, the Test of Basic Science Process Skills, digital photography of plate waste, PolarActive accelerometers, anthropometrics, a parent questionnaire, and the School and Community Actions for Nutrition survey. Evaluation will include quantitative and qualitative measures. Quantitative data will use paired t, chi-square, and Mann-Whitney U tests and regression modeling using P = .05 to determine statistical significance.

Workers' conditions in accordance with their place of work are different from one area to another, especially in this reformation era where there are immense alterations in politics shown from the centralized government shifting to decentralization and district autonomy. Ergonomics problems in Indonesia are reviewed. In home industries, workers have to adjust themselves to their jobs, and ergonomic improvement may face significant impediments especially in small-scale industries. It is necessary to create or identify the most plausible model to be implemented in accordance with the conditions of districts, including low awareness about the relation between ergonomics and workers' productivity in producing goods and services and working processes scattered often at their own houses. As conditions conducive to ergonomics programs, district-level willingness to improve and increase the wealth of their society, recognition by businesses about the impacts of ergonomics on productivity and reduction of medical treatment costs may be mentioned. Labor unions support ergonomic improvements at production processes, and professionals and academicians are ready to assist, whereas national banks and foreign investment may encourage new technologies including ergonomics aspects. It is important to strengthen ergonomic improvement efforts in Indonesia through establishing district ergonomics improvement networks and ergonomics peer leaders with the support of continual training starting from the training of core leaders at the province level and extending to peer leaders at district level. This training should be made as simple as possible in order to facilitate innovations toward changes. Finally assistance is needed by the mentor teams in order to periodically monitor the improvements undertaken.

The relationship between research and practice in ergonomics and human factors has rarely been addressed in the literature. This presents specific problems for researchers when seeking to relate their work to the research community. Equally, practitioners are often frustrated by the lack of appropriate research to meet their needs. This paper seeks to identify current drivers for ergonomics research along with an analysis of how these are changing. Specifically, the use of bibliometric data to assess research output and its impact on a multi-disciplinary subject such as ergonomics is examined. Areas where action may be required to stimulate better research and improved practice are proposed. These include a greater role for the practitioner in completing the circle of knowledge and improving the evidence base for practice with, in particular, practitioners becoming more active in determining research priorities. It is concluded that combined effort is needed by researcher and practitioner communities to enable and promote a more effective understanding of the true impact of ergonomics across industry and society. STATEMENT OF RELEVANCE: The relationship between ergonomics research and practice is examined. Research 'drivers' are identified, including the influence of bibliometric data. Implications for researchers and practitioners are discussed. The role of practitioners in completing the circle of knowledge and improving the ergonomics evidence base is stressed, as is the need to promote the impact of ergonomics across society.

Tested a family-based group problem-solving intervention, "Families Taking Control," (FTC) to improve school functioning and health-related quality of life (HRQL) for children with sickle cell disease. Children and caregivers completed questionnaires assessing HRQL and school functioning and children completed performance-based measures of IQ and achievement at baseline and 6 months later. Families were randomized to the intervention (FTC, n = 42) or delayed intervention control (DIC, n = 41) group. FTC involved a full-day workshop followed by 3 booster calls. There were no differences between FTC completers (n = 24) and noncompleters (n = 18). FTC group (n = 24) and DIC group (n = 38) did not differ significantly on primary outcomes at follow-up: number of formal academic and disease-related accommodations, individualized education plan/504 service plan, school absences, school HRQL, or academic skills. Although families found FTC to be acceptable, there were no intervention effects. Challenges of the trial and implications for future research are discussed. © The Author 2015.

2018-06-01

While media education and reduction programs have been proposed to prevent adverse health and academic outcomes related to heavy electronic media use among school-aged children, few have been formally piloted and evaluated. We used a quasi-experimental design to evaluate the effectiveness of Take the Challenge (TtC), a school-based media education/reduction program for the primary prevention of sleep deprivation, dysfunctional social-emotional behaviors, and poor academic performance. Sixth- to eighth-grade students at a rural Midwestern U.S. middle school received the TtC program, while a similar school in the same district served as the comparison group. Health-related and academic measures were collected from students and teachers at both schools before and after the intervention. The primary outcome measure was student-reported electronic media use (television, video games, Internet). Secondary measures included student health behaviors (student-reported sleep, exercise, and outdoor play) and academic activities (teacher-reported homework and classroom performance). Compared to the comparison group, students receiving TtC slept more and reduced television viewing, background television time, after-school video gaming, and weekend Internet use. Teachers reported increases in the extent to which TtC students completed homework assignments and stayed on task in the classroom. Well-designed school-based programs such as TtC can reduce electronic media use among middle-school children and improve related health and academic outcomes.

To review elements of an ergonomic operating room environment and describe common ergonomic errors in surgeon posture during laparoscopic and robotic surgery. Descriptive video based on clinical experience and a review of the literature (Canadian Task Force classification III). Community teaching hospital affiliated with a major teaching hospital. Gynecologic surgeons. Demonstration of surgical ergonomic principles and common errors in surgical ergonomics by a physical therapist and surgeon. The physical nature of surgery necessitates awareness of ergonomic principles. The literature has identified ergonomic awareness to be grossly lacking among practicing surgeons, and video has not been documented as a teaching tool for this population. Taking this into account, we created a video that demonstrates proper positioning of monitors and equipment, and incorrect and correct ergonomic positions during surgery. Also presented are 3 common ergonomic errors in surgeon posture: forward head position, improper shoulder elevation, and pelvic girdle asymmetry. Postural reset and motion strategies are demonstrated to help the surgeon learn techniques to counterbalance the sustained and awkward positions common during surgery that lead to muscle fatigue, pain, and degenerative changes. Correct ergonomics is a learned and practiced behavior. We believe that video is a useful way to facilitate improvement in ergonomic behaviors. We suggest that consideration of operating room setup, proper posture, and practice of postural resets are necessary components for a longer, healthier, and pain-free surgical career.

We conducted a cluster-randomized trial to assess the impact of a school-based water treatment, hygiene, and sanitation program on reducing infection with soil-transmitted helminths (STHs) after school-based deworming. We assessed infection with STHs at baseline and then at two follow-up rounds 8 and 10 months after deworming. Forty government primary schools in Nyanza Province, Kenya were randomly selected and assigned to intervention or control arms. The intervention reduced reinfection prevalence (odds ratio [OR] 0.56, 95% confidence interval [CI] 0.31–1.00) and egg count (rate ratio [RR] 0.34, CI 0.15–0.75) of Ascaris lumbricoides. We found no evidence of significant intervention effects on the overall prevalence and intensity of Trichuris trichiura, hookworm, or Schistosoma mansoni reinfection. Provision of school-based sanitation, water quality, and hygiene improvements may reduce reinfection of STHs after school-based deworming, but the magnitude of the effects may be sex- and helminth species-specific.

Full Text Available Abstract Background Since stakeholders’ active engagement is essential for public health strategies to be effective, this review is focused on intervention designs and outcomes of school- and community-based noncommunicable disease (NCD prevention interventions involving children and young people. Methods The review process was based on the principles of scoping reviews. A systematic search was conducted in eight major databases in October 2015. Empirical studies published in English, French, Portuguese, and Spanish were considered. Five selection criteria were applied. Included in the review were (1 empirical studies describing (2 a health intervention focused on diet and/or physical activity, (3 based on children’s and young people’s involvement that included (4 a relationship between school and local community while (5 providing explicit information about the outcomes of the intervention. The search provided 3995 hits, of which 3253 were screened by title and abstract, leading to the full-text screening of 24 papers. Ultimately, 12 papers were included in the review. The included papers were analysed independently by at least two reviewers. Results Few relevant papers were identified because interventions are often either based on children’s involvement or are multi-setting, but rarely both. Children were involved through participation in needs assessments, health committees and advocacy. School-community collaboration ranged from shared activities, to joint interventions with common goals and activities. Most often, collaboration was school-initiated. Most papers provided a limited description of the outcomes. Positive effects were identified at the organisational level (policy, action plans, and healthy environments, in adult stakeholders (empowerment, healthy eating and in children (knowledge, social norms, critical thinking, and health behaviour. Limitations related to the search and analytical methods are discussed. Conclusion

Two comparable schools were randomly assigned to either the intervention or control group. Then, 310 students in the randomly selected classrooms were allocated to each group. The intervention group received the self-regulation program with school and family involvement to prevent gaming addiction. Master teachers attended in-house training on prevention of gaming addiction in children. Parents of these children received a gaming addiction prevention manual and guidelines. The program lasted 8 weeks. The control group received no intervention. Knowledge and Attitude About Gaming Questionnaire, Game Addiction Screening Test (GAST, and Game Addiction Protection Scale were utilized to assess subjects at baseline, immediately after, and 3 months post-intervention. Descriptive statistics, chi-square, and independent t-test were used to describe characteristics of the participants, and repeated measures ANOVA was analyzed to test the effectiveness of the intervention. Results: The findings revealed that there were significant differences in knowledge

Schools are repeatedly utilised as a key setting for health interventions. However, the translation of effective research findings to the school setting can be problematic. In order to improve effective translation of future interventions, it is imperative key challenges and facilitators of implementing health interventions be understood from a school's perspective. Nineteen semi-structured interviews were conducted in primary schools (headteachers n = 16, deputy headteacher n = 1, healthy school co-ordinator n = 2). Interviews were transcribed verbatim and analysed using thematic analysis. The main challenges for schools in implementing health interventions were; government-led academic priorities, initiative overload, low autonomy for schools, lack of staff support, lack of facilities and resources, litigation risk and parental engagement. Recommendations to increase the application of interventions into the school setting included; better planning and organisation, greater collaboration with schools and external partners and elements addressing sustainability. Child-centred and cross-curricular approaches, inclusive whole school approaches and assurances to be supportive of the school ethos were also favoured for consideration. This work explores schools' perspectives regarding the implementation of health interventions and utilises these thoughts to create guidelines for developing future school-based interventions. Recommendations include the need to account for variability between school environments, staff and pupils. Interventions with an element of adaptability were preferred over the delivery of blanket fixed interventions. Involving schools in the developmental stage would add useful insights to ensure the interventions can be tailored to best suit each individual schools' needs and improve implementation.

Full Text Available With growing evidence for the positive health outcomes associated with a plant-based diet, the study’s purpose was to examine the potential of shifting adolescents’ food choices towards plant-based foods. Using a real world setting of a school canteen, a set of small changes to the choice architecture was designed and deployed in a secondary school in Yorkshire, England. Focussing on designated food items (whole fruit, fruit salad, vegetarian daily specials, and sandwiches containing salad the changes were implemented for six weeks. Data collected on students’ food choice (218,796 transactions enabled students’ (980 students selections to be examined. Students’ food choice was compared for three periods: baseline (29 weeks; intervention (six weeks; and post-intervention (three weeks. Selection of designated food items significantly increased during the intervention and post-intervention periods, compared to baseline (baseline, 1.4%; intervention 3.0%; post-intervention, 2.2% χ2(2 = 68.1, p < 0.001. Logistic regression modelling also revealed the independent effect of the intervention, with students 2.5 times as likely (p < 0.001 to select the designated food items during the intervention period, compared to baseline. The study’s results point to the influence of choice architecture within secondary school settings, and its potential role in improving adolescents’ daily food choices.

The aim of the study was to investigate if voice ergonomic risk factors in classrooms correlated with acoustic parameters of teachers' voice production. The voice ergonomic risk factors in the fields of working culture, working postures and indoor air quality were assessed in 40 classrooms using the Voice Ergonomic Assessment in Work Environment - Handbook and Checklist. Teachers (32 females, 8 males) from the above-mentioned classrooms recorded text readings before and after a working day. Fundamental frequency, sound pressure level (SPL) and the slope of the spectrum (alpha ratio) were analyzed. The higher the number of the risk factors in the classrooms, the higher SPL the teachers used and the more strained the males' voices (increased alpha ratio) were. The SPL was already higher before the working day in the teachers with higher risk than in those with lower risk. In the working environment with many voice ergonomic risk factors, speakers increase voice loudness and use more strained voice quality (males). A practical implication of the results is that voice ergonomic assessments are needed in schools. Copyright © 2013 S. Karger AG, Basel.

To establish the inter-rater reliability of an observation-based ergonomics assessment checklist for computer workers. A 37-item (38-item if a laptop was part of the workstation) comprehensive observational ergonomics assessment checklist comparable to government guidelines and up to date with empirical evidence was developed. Two trained practitioners assessed full-time office workers performing their usual computer-based work and evaluated the suitability of workstations used. Practitioners assessed each participant consecutively. The order of assessors was randomised, and the second assessor was blinded to the findings of the first. Unadjusted kappa coefficients between the raters were obtained for the overall checklist and subsections that were formed from question-items relevant to specific workstation equipment. Twenty-seven office workers were recruited. The inter-rater reliability between two trained practitioners achieved moderate to good reliability for all except one checklist component. This checklist has mostly moderate to good reliability between two trained practitioners. Practitioner Summary: This reliable ergonomics assessment checklist for computer workers was designed using accessible government guidelines and supplemented with up-to-date evidence. Employers in Queensland (Australia) can fulfil legislative requirements by using this reliable checklist to identify and subsequently address potential risk factors for work-related injury to provide a safe working environment.

What do parents think about parental participation in school-based interventions on energy balance-related behaviours? a qualitative study in 4 countries

Science.gov (United States)

2011-01-01

Background Overweight and obesity in youth has increased dramatically. Therefore, overweight prevention initiatives should start early in life and target modifiable energy balance-related behaviours. Parental participation is often advocated as important for school-based interventions, however, getting parents involved in school-based interventions appears to be challenging based on earlier intervention experiences. The purpose of this study was to get insight into the determinants of and perspectives on parental participation in school-interventions on energy balance-related behaviours (physical activity, healthy eating, sedentary behaviours) in parents of ten- to twelve-year olds in order to develop an effective parental module for school-based interventions concerning energy balance-related behaviours. Methods Four countries (Belgium, Hungary, Norway and Spain) conducted the focus group research based on a standardised protocol and a semi-structured questioning route. A variation in parental socio-economic status (SES) and parental school involvement was taken into account when recruiting the parents. The audio taped interviews were transcribed, and a qualitative content analysis of the transcripts was conducted in each country. Results Seventeen focus group interviews were conducted with a total of 92 parents (12 men, 80 women). Physical activity was considered to be a joint responsibility of school and parents, nutrition as parent's responsibility but supported by the school, and prevention of sedentary behaviours as parent's sole responsibility. Parents proposed interactive and practical activities together with their child as the best way to involve them such as cooking, food tasting, nutrition workshops, walking or cycling tours, sport initiations together with their child. Activities should be cheap, on a convenient moment, focused on their children and not on themselves, not tutoring, not theoretical, and school-or home-based. Conclusions Parents want to

In Iranian orthotic and prosthetic workshops, the majority of activities are carried out by manpower and the tasks are labor-intensive. In these workshops, ergonomic aspects of working conditions are seldom considered. This study was conducted in orthotic and prosthetic workshops with the objectives of determination of prevalence rate of MSDs among employees and assessment of ergonomics working conditions. In this cross-sectional study, all employees (n = 42; 29 males and 13 females) in 11 active orthotic and prosthetic production centers of Shiraz city participated. Data were collected using Nordic Musculoskeletal disorders Questionnaire (NMQ) and observational technique by an ergonomics checklist for assessment of working conditions. The means (SD) of age and job tenure (years) in the study individuals were 37.26 (10.21) and 12.8 (9.39), respectively. The most prevalent MSD symptoms in the past 12 months were reported in the lower back (42.9%), shoulders (40.5%) and knees (40.5%). Working conditions assessment showed that the main ergonomic problems in the workshops studied originated from awkward working posture, improper workstation design, poorly designed hand tools and incorrect manual material handling. Any interventional program for working conditions improvement should, therefore, focus on these areas.

Full Text Available School-based programs and policies can reduce student smoking rates. However, their impact on never-smoking students has not been investigated despite the clear transition between non-susceptible, susceptible, and ever tried smoking statuses. The objective of this paper was to examine the longitudinal student-level impact of six changes in school-based tobacco control programs and policies on student transitions in susceptibility to smoking over one year. Two multinomial logistic regression models identified the relative risk of a change in self-reported susceptibility to smoking or in trying a cigarette among never-smoking students in each of the six intervention schools compared to the relative risk among never-smoking students in control schools. Model 1 identified the relative risk of a change in smoking susceptibility status among baseline non-susceptible never smoking students, while Model 2 identified the relative risk of a change in smoking susceptibility status among baseline susceptible never smoking students. Students at some intervention schools were at increased risk of becoming susceptible to or trying a cigarette at one year follow-up. Intervention studies should examine changes to susceptibility to future smoking when evaluating impact to ensure that school-based tobacco control programs and policies do not negatively change the risk status of never-smoking students.

Questions related to job skills and the teaching situations that best promote skill development are investigated by specialists in various fields, notably among them, ergonomists. This paper presents the findings of an ergonomic intervention study whose aim was to develop a meat-deboning training program by taking into account both the training content to be constructed and the working conditions that might facilitate or hinder skill development. One-on-one interviews and group discussions, on-the-job and videotape playback observations, as well as self-confrontation interviews were carried out. Activity analysis revealed major variability in work methods. The reasoning behind the experienced workers' actions and the experiential job knowledge they had developed were brought to light and served to develop the training content. The determining factors in the choice of work methods were identified, allowing adjustments to be made to the working conditions that might hinder skill development. The ergonomic process that implied taking working conditions into account in our study may make a significant contribution to vocational didactics, which is based on the cognitive analysis of work for the purpose of improving the effectiveness of job-skills training.

Noncommunicable diseases (NCD) are the most common causes of morbidity and mortality worldwide, even in low- and middle-income countries (LMIC). Recent trends in health promotion emphasize community-based interventions as an important strategy for improving health outcomes. The aim of this study was to conduct formative research regarding the perceptions of NCD risk factors, their influencing factors, and community resources available to aid the development and implementation of a community-based intervention with school-age children. Focus group discussions (n = 18), home visits (n = 30), and individual semi-structured interviews (n = 26) were conducted in three urban communities in Guatemala with school-age children (10-12 years of age), teachers, parents, and local community members (i.e., school principals, school food kiosk vendors, religious leaders, authority representatives). All focus groups and interviews were transcribed verbatim for thematic analysis. Children, parents, and teachers have general knowledge about modifiable risk factors. Adults worried more about tobacco use, as compared to unhealthy diet and physical inactivity in children. Participants identified features at the intrapersonal (e.g., negative emotional state), interpersonal (e.g., peers as role models), and organizational and community levels (e.g., high levels of crime) that influence these risk factors in children. School committees, religious leaders, and government programs and activities were among the positive community resources identified. These findings should help researchers in Guatemala and similar LMIC to develop community-based interventions for NCD prevention in school-age children that are effective, feasible, and culturally acceptable.

The current academic literature suggests there is a potential for using gardening as a tool to improve children's fruit and vegetable intake. This study is two parallel randomised controlled trials (RCT) devised to evaluate the school gardening programme of the Royal Horticultural Society (RHS) Campaign for School Gardening, to determine if it has an effect on children's fruit and vegetable intake. Trial One will consist of 26 schools; these schools will be randomised into two groups, one to receive the intensive intervention as "Partner Schools" and the other to receive the less intensive intervention as "Associate Schools". Trial Two will consist of 32 schools; these schools will be randomised into either the less intensive intervention "Associate Schools" or a comparison group with delayed intervention. Baseline data collection will be collected using a 24-hour food diary (CADET) to collect data on dietary intake and a questionnaire exploring children's knowledge and attitudes towards fruit and vegetables. A process measures questionnaire will be used to assess each school's gardening activities. The results from these trials will provide information on the impact of the RHS Campaign for School Gardening on children's fruit and vegetable intake. The evaluation will provide valuable information for designing future research in primary school children's diets and school based interventions. ISRCTN11396528.

sub-Saharan Africa (Malawi, South Africa, Tanzania, Zimbabwe, and Kenya), one in Latin America (Chile), and two in Europe (England and Scotland). Sexual and reproductive health educational programmes Six trials evaluated school-based educational interventions. In these trials, the educational programmes evaluated had no demonstrable effect on the prevalence of HIV (RR 1.03, 95% CI 0.80 to 1.32, three trials; 14,163 participants; low certainty evidence), or other STIs (herpes simplex virus prevalence: RR 1.04, 95% CI 0.94 to 1.15; three trials, 17,445 participants; moderate certainty evidence; syphilis prevalence: RR 0.81, 95% CI 0.47 to 1.39; one trial, 6977 participants; low certainty evidence). There was also no apparent effect on the number of young women who were pregnant at the end of the trial (RR 0.99, 95% CI 0.84 to 1.16; three trials, 8280 participants; moderate certainty evidence). Material or monetary incentive-based programmes to promote school attendance Two trials evaluated incentive-based programmes to promote school attendance. In these two trials, the incentives used had no demonstrable effect on HIV prevalence (RR 1.23, 95% CI 0.51 to 2.96; two trials, 3805 participants; low certainty evidence). Compared to controls, the prevalence of herpes simplex virus infection was lower in young women receiving a monthly cash incentive to stay in school (RR 0.30, 95% CI 0.11 to 0.85), but not in young people given free school uniforms (Data not pooled, two trials, 7229 participants; very low certainty evidence). One trial evaluated the effects on syphilis and the prevalence was too low to detect or exclude effects confidently (RR 0.41, 95% CI 0.05 to 3.27; one trial, 1291 participants; very low certainty evidence). However, the number of young women who were pregnant at the end of the trial was lower among those who received incentives (RR 0.76, 95% CI 0.58 to 0.99; two trials, 4200 participants; low certainty evidence).

School-based interventions for preadolescents provide the opportunity, in a ubiquitous institutional setting, to attack stigmatizing attitudes before they are firmly entrenched, and thus they may reduce mental illness stigma in the overall population. This study evaluated the effectiveness of classroom-based interventions in reducing stigma and increasing understanding of mental illness and positive attitudes toward treatment seeking among sixth-grade students. In an ethnically and racially diverse sample (N=721), 40% of participants were Latino, 26% were white, and 24% were African American; the mean age was 11.5. In a fully crossed design, classrooms from a school district in Texas were randomly assigned to receive all three, two, one, or none of the following interventions: a PowerPoint- and discussion-based curriculum, contact with two college students who described their experiences with mental illness, and exposure to antistigma printed materials. Standard and vignette-based quantitative measures of mental health knowledge and attitudes, social distance, and help-seeking attitudes were assessed pre- and postintervention. Printed materials had no significant effects on outcomes and were grouped with the control condition for analysis. For eight of 13 outcomes, the curriculum-only group reported significantly more positive outcomes than the control group; the largest between-group differences were for stigma awareness and action, recognition of mental illness in the vignettes, and positive orientation to treatment. The contact-alone group reported significantly more positive outcomes on three vignette-based measures. Results were most promising for a classroom-based curriculum that can be relatively easily disseminated to and delivered by teachers, offering the potential for broad application in the population.

Snacks play an important role in child health and nutritional status. Schools are considered as the preferred place to encourage healthy eating among children. The aim of this study was to evaluate the effect of buffet school-based intervention on acceptance and satisfaction of parents and students in Iran. Primary school students (n = 1120, 68.83% girls) from first to third grade, with one of their parents, participated in this prospective field trial study conducted in Isfahan, Iran. The study was consisted of three phases; schools selection, kitchen selection, implementation including two different parts, getting order and distribution. We provided hot snacks as traditional and healthy fast food according to taste and food preferences of children. Acceptance and satisfaction of parents and students were evaluated via a researcher made questionnaire before and after the intervention in one-third of participants as a representative sample of students who ordered the snacks. Most of the students usually ate snack in the break-time at school, the eagerness of provided snacks was 98.8% and 63.6% in girls and boys, respectively. The most interesting tastes were Ashe Reshteh and Tahchin, (45.1% girls vs. 36.8% boys), while bean (among girls) and Ashe Jo (among boys) were ranked as the lowest. More than half of parents (66.7%) evaluated the price of snacks as "acceptable," showing their satisfaction. Results of this study indicate that school-based interventions accompanied with parental and principals' support is considered as a practical approach to promote healthful eating at an early age. Developing effective interventions for youth might, therefore, help to prevent unhealthy dietary choices becoming habitual.

To qualitatively describe interventions by schools to meet children's needs after the May 2011 Joplin, Missouri tornado. Qualitative exploratory study conducted six months after the tornado. Key informant interviews with school staff (teachers, psychologists, guidance counselor, nurse, principal), public health official, and physicians. After the tornado, school staff immediately worked to contact every enrolled child to provide assistance and coordinate recovery services. Despite severe damage to half of the city's schools, the decision was made to reopen schools at the earliest possible time to provide a safe, reassuring environment and additional services. An expanded summer school session emphasized child safety and emotional wellbeing. The 2011-2012 school year began on time, less than three months after the disaster, using temporary facilities. Displaced children were bused to their usual schools regardless of their new temporary residence locations. In just-in-time training sessions, teachers developed strategies to support students and staff experiencing anxiety or depression. Certified counselors conducted school-based, small-group counseling for students. Selective referrals were made to community mental health providers for children with greatest needs. Evidence from Joplin adds to a small body of empirical experience demonstrating the important contribution of schools to postdisaster community recovery. Despite timely and proactive services, many families and children struggled after the tornado. Improvements in the effectiveness of postdisaster interventions at schools will follow from future scientific evidence on optimal approaches.

2009-01-01

Purpose: investigation of the influence of CT-based navigation systems on the success of an intervention, assessment of the advantages and disadvantages of the utilized systems, and evaluation of the ergonomic system properties. Materials and method: a simple guiding system PatPos Invent trademark and the computer-based navigation system PinPoint trademark were employed on two CT systems. In order to investigate the influence of the navigation aids on the success of the interventions, 96 prospective, randomized, and standardized punctures were performed on a specifically developed, rigid phantom. 16 examiners punctured 6 targets with 3 degrees of difficulty with the navigation aids. Results: irrespective of the experience of the examiner, both navigation systems guided the target with an equal degree of certainty. PinPoint significantly reduced the length of the examination time (12 - 25 min) as compared to PatPos Invent (20 - 40 min). The expectation conformity and comprehensibility of PatPos Invent were assessed significantly more positively than PinPoint with regard to the general handling of the system. In contrast, the assessment of the usability during preoperative setup favored PinPoint. The type of navigation system has no influence on the precision of the implementation of a puncture procedure.

Background Although the number of smokers has declined in the last decade, smoking is still a major health problem among youngsters and adolescents. For this reason, there is a need for effective smoking prevention programmes targeting primary school children. A web-based computer-tailored feedback programme may be an effective intervention to stimulate youngsters not to start smoking, and increase their knowledge about the adverse effects of smoking and their attitudes and self-efficacy regarding non-smoking. Methods & design This paper describes the development and evaluation protocol of a web-based out-of-school smoking prevention programme for primary school children (age 10-13 years) entitled ‘Fun without Smokes’. It is a transformation of a postal mailed intervention to a web-based intervention. Besides this transformation the effects of prompts will be examined. This web-based intervention will be evaluated in a 2-year cluster randomised controlled trial (c-RCT) with three study arms. An intervention and intervention + prompt condition will be evaluated for effects on smoking behaviour, compared with a no information control condition. Information about pupils’ smoking status and other factors related to smoking will be obtained using a web-based questionnaire. After completing the questionnaire pupils in both intervention conditions will receive three computer-tailored feedback letters in their personal e-mail box. Attitudes, social influences and self-efficacy expectations will be the content of these personalised feedback letters. Pupils in the intervention + prompt condition will - in addition to the personalised feedback letters - receive e-mail and SMS messages prompting them to revisit the ‘Fun without Smokes’ website. The main outcome measures will be ever smoking and the utilisation of the ‘Fun without Smokes’ website. Measurements will be carried out at baseline, 12 months and 24 months of follow-up.

Adolescent males are less likely to receive health care and have lower levels of sexual and reproductive health (SRH) knowledge than adolescent females. The purpose of this study was to determine if a school-based structural intervention focused on school nurses increases receipt of condoms and SRH information among male students. Interventions to improve student access to sexual and reproductive health care were implemented in six urban high schools with a matched set of comparison schools. Interventions included working with school nurses to improve access to sexual and reproductive health care, including the provision of condoms and information about pregnancy and sexually transmitted disease prevention and services. Intervention effects were assessed through five cross-sectional yearly surveys, and analyses include data from 13,740 male students. Nurses in intervention schools changed their interactions with male students who visited them for services, such that, among those who reported they went to the school nurse for any reason in the previous year, those in intervention schools reported significant increases in receipt of sexual health services over the course of the study compared with students in comparison schools. Further, these results translated into population-level effects. Among all male students surveyed, those in intervention schools were more likely than those in comparison schools to report increases in receipt of sexual health services from school nurses. With a minimal investment of resources, school nurses can become important sources of SRH information and condoms for male high school students. Published by Elsevier Inc.

Full Text Available Abstract Background Physical inactivity is recognised as a public health concern within children and interventions to increase physical activity are needed. The purpose of this research was to evaluate the effect of a school-based healthy lifestyles intervention on physical activity, fruit and vegetable consumption, body composition, knowledge, and psychological variables. Method A non-randomised controlled study involving 8 primary schools (4 intervention, 4 control. Participants were 589 children aged 7–11 years. The intervention lasted 10 months and comprised a CD-rom learning and teaching resource for teachers; an interactive website for pupils, teachers and parents; two highlight physical activity events (1 mile school runs/walks; a local media campaign; and a summer activity wall planner and record. Primary outcome measures were objectively measured physical activity (pedometers and accelerometers and fruit and vegetable consumption. Secondary outcomes included body mass index, waist circumference, estimated percent body fat, knowledge, psychological variables. Multi-level modelling was employed for the data analysis. Results Relative to children in control schools, those in intervention schools significantly increased their total time in moderate-to-vigorous physical activity (MVPA (by 9 minutes/day vs a decrease of 10 minutes/day, their time in MVPA bouts lasting at least one minute (10 minutes/day increase vs no change and increased daily steps (3059 steps per day increase vs 1527 steps per day increase. A similar pattern of results was seen in a subset of the least active participants at baseline. Older participants in intervention schools showed a significant slowing in the rate of increase in estimated percent body fat, BMI, and waist circumference. There were no differences between groups in fruit and vegetable intake. Extrinsic motivation decreased more in the intervention group. Conclusion The intervention produced positive

Full Text Available High school students are a common target group in initiatives addressing discriminatory attitudes towards people with mental illness. However, these initiatives are rarely evaluated and documented. The aim of our paper is to evaluate the effectiveness of a school-based educational intervention for improving adolescents’ attitudes and reducing the desire for social distance from people with mental illness living in their community. A total of 161 students aged 16-18 years old were questioned at baseline assessment and 86 of them received a three-workshop educational intervention while 75 students comprised the control group. A follow-up assessment 1 month post intervention evaluated its impact. Attitudes and the social distance were assessed through the Community Attitudes towards the Mentally Ill scale and a 10-statement questionnaire based on the Self-report Inventory of Fear and Behavioural Intentions, respectively. Data from 140 subjects were analyzed. All attitude dimensions and half of the measured social distance statements were significantly improved in the intervention group at follow up assessment compared to controls. However, the statements measuring more intimate types of social relationships did not change significantly post intervention. In conclusion, short educational interventions can be effective to some extent in reducing discriminatory attitudes towards people with mental illness. However, effective interventions to address deeply held negative stereotypes will require further research.

Full Text Available Type 1 diabetes is one of the most common chronic childhood diseases, while type 2 diabetes in children is increasing at alarming rates globally. Against this backdrop, the school is a critical environment for children with diabetes. They continue to face barriers to education that may lead to depression, poor academic performance, and poor quality of life. To address these challenges, diabetes interventions have been implemented in school and the goal was to systematically review these interventions and their outcomes between 2000 and 2013. Fifteen studies were included in the narrative synthesis. Education of school personnel was the main focus before 2006. Studies reported gains in knowledge and perceived confidence of school staff. Since 2006, more comprehensive interventions have been developed to promote better care coordination and create a safe school environment. These studies reported improved diabetes management and quality of life of students. Assessment tools varied and study design included randomized controlled trials, quantitative and qualitative methods. Although many of the studies reported a significant difference in the parameters measured, it was not possible to determine optimal ways to improve the health, quality of life and academic performance of children with diabetes, given the disparity in scope, assessment tools and measured outcomes. Experimental designs, longer follow-up studies, larger sample sizes, and a higher number of participating schools are critical issues to consider in future studies. Most of the research was conducted in North America and further research is needed in other parts of the world.

Fundamental movement skill (FMS) competence is positively associated with physical activity (PA). However, levels of both FMS and PA are lower than expected. Current reviews of interventions to improve FMS and PA have shown that many school-based programs have achieved positive outcomes, yet the maintenance of these interventions is variable. Teachers play a central role in the success and longevity of school-based interventions. Despite the importance of teacher engagement, research into the nature and quality of teacher training in school-based PA and FMS interventions has received little attention. The aim of this systematic review was to investigate the type and quantity of teacher training in school-based physical education PA and/or FMS interventions, and to identify what role teacher training had on the intervention outcome. A systematic search of eight electronic databases was conducted. Publication date restrictions were not implemented in any database, and the last search was performed on 1 March 2015. School physical education-based interventions facilitated by a school teacher, and that included a quantitative assessment of FMS competence and/or PA levels were included in the review. The search identified 39 articles. Eleven of the studies measured FMS, 25 studies measured PA and three measured both FMS and PA. Nine of the studies did not report on any aspect of the teacher training conducted. Of the 30 studies that reported on teacher training, 25 reported statistically significant intervention results for FMS and/or PA. It appears that teacher training programs: are ≥ 1 day; provide comprehensive subject and pedagogy content; are framed by a theory or model; provide follow-up or ongoing support; and measure teacher satisfaction of the training, are more effective at improving student outcomes in FMS and/or PA. However, the provision of information regarding the characteristics of the teacher training was largely inadequate. Therefore, it was

Telehealth approaches to delivering ergonomics assessment hold great potential to improve service delivery in rural and remote settings. This case study describes a telehealth-based ergonomics service delivery process, and compares in-person and telehealth-based ergonomics approaches at an Alberta-based non-profit advocacy group. This project demonstrates that telehealth approaches to ergonomics do not lead to significantly different scoring outcomes for assessment of ergonomics issues, when compared to in-person assessments. This project also outlines the importance of live real-time video conferencing to improving communication, attaining key assessment information, and demonstrating ergonomic adjustments. However, some key considerations of bandwidth and hardware capabilities need to be taken into account. Key communication strategies are outlined to improve rapport, maintain employee confidentiality, and reduce client anxiety around telehealth ergonomics assessments. This project provides further support for telehealth approaches to office ergonomics, and outlines some key implementation strategies and barriers that should be considered.

Full Text Available Individuals with severe neuromuscular impairments face many challenges in communication and manipulation of the environment. Brain-computer interfaces (BCIs show promise in presenting real-world applications that can provide such individuals with the means to interact with the world using only brain waves. Although there has been a growing body of research in recent years, much relates only to technology, and not to technology in use—i.e., real-world assistive technology employed by users. This review examined the literature to highlight studies that implicate the human factors and ergonomics (HFE of P300-based BCIs. We assessed 21 studies on three topics to speak directly to improving the HFE of these systems: (1 alternative signal evocation methods within the oddball paradigm; (2 environmental interventions to improve user performance and satisfaction within the constraints of current BCI systems; and (3 measures and methods of measuring user acceptance. We found that HFE is central to the performance of P300-based BCI systems, although researchers do not often make explicit this connection. Incorporation of measures of user acceptance and rigorous usability evaluations, increased engagement of disabled users as test participants, and greater realism in testing will help progress the advancement of P300-based BCI systems in assistive applications.

Gender-based generalisations in school nurses' appraisals of and interventions addressing students' mental health.

Rosvall, Per-Åke; Nilsson, Stefan

2016-08-30

There has been an increase of reports describing mental health problems in adolescents, especially girls. School nurses play an important role in supporting young people with health problems. Few studies have considered how the nurses' gender norms may influence their discussions. To investigate this issue, semi-structured interviews focusing on school nurses' work with students who have mental health problems were conducted. Transcripts of interviews with Swedish school nurses (n = 15) from the Help overcoming pain early project (HOPE) were analysed using theories on gender as a theoretical framework and then organised into themes related to the school nurses' provision of contact and intervention. The interviewees were all women, aged between 42-63 years, who had worked as nurses for 13-45 years, and as school nurses for 2-28 years. Five worked in upper secondary schools (for students aged 16-19) and 10 in secondary schools (for students aged 12-16). The results show that school nurses more commonly associated mental health problems with girls. When the school nurses discussed students that were difficult to reach, boys in particular were mentioned. However, very few nurses mentioned specific intervention to address students' mental health problems, and all of the mentioned interventions were focused on girls. Some of the school nurses reported that it was more difficult to initiate a health dialogue with boys, yet none of the nurses had organized interventions for the boys. We conclude that generalisations can sometimes be analytically helpful, facilitating, for instance, the identification of problems in school nurses' work methods and interventions. However, the most important conclusion from our research, which applied a design that is not commonly used, is that more varied approaches, as well as a greater awareness of potential gender stereotype pitfalls, are necessary to meet the needs of diverse student groups.

Nature is presented as a new paradigm for ergonomics. As a discipline concerned with well-being, the importance of natural environments for wellness should be part of ergonomics knowledge and practice. This position is supported by providing a concise summary of the evidence of the value of the natural environment to well-being. Further, an emerging body of research has found relationships between well-being and a connection to nature, a concept that reveals the integrative character of human experience which can inform wider practice and epistemology in ergonomics. Practitioners are encouraged to bring nature into the workplace, so that ergonomics keeps pace with the move to nature-based solutions, but also as a necessity in the current ecological and social context. Practitioner Summary: Nature-based solutions are coming to the fore to address societal challenges such as well-being. As ergonomics is concerned with well-being, there is a need for a paradigm shift in the discipline. This position is supported by providing a concise summary of the evidence of the value of the natural environment to well-being.

Full Text Available Abstract Background Overweight and obesity in youth has increased dramatically. Therefore, overweight prevention initiatives should start early in life and target modifiable energy balance-related behaviours. Parental participation is often advocated as important for school-based interventions, however, getting parents involved in school-based interventions appears to be challenging based on earlier intervention experiences. The purpose of this study was to get insight into the determinants of and perspectives on parental participation in school-interventions on energy balance-related behaviours (physical activity, healthy eating, sedentary behaviours in parents of ten- to twelve-year olds in order to develop an effective parental module for school-based interventions concerning energy balance-related behaviours. Methods Four countries (Belgium, Hungary, Norway and Spain conducted the focus group research based on a standardised protocol and a semi-structured questioning route. A variation in parental socio-economic status (SES and parental school involvement was taken into account when recruiting the parents. The audio taped interviews were transcribed, and a qualitative content analysis of the transcripts was conducted in each country. Results Seventeen focus group interviews were conducted with a total of 92 parents (12 men, 80 women. Physical activity was considered to be a joint responsibility of school and parents, nutrition as parent's responsibility but supported by the school, and prevention of sedentary behaviours as parent's sole responsibility. Parents proposed interactive and practical activities together with their child as the best way to involve them such as cooking, food tasting, nutrition workshops, walking or cycling tours, sport initiations together with their child. Activities should be cheap, on a convenient moment, focused on their children and not on themselves, not tutoring, not theoretical, and school-or home-based

Adequate application of the static and dynamic anthropometric measures of pre-school children in ergonometric design of children's playground equipment should eliminate all dangers and difficulties in their use. Possibilities of injuries, insecure movements, discomfort able positions and some other dangerous actions may be minimized; and safety and health protection of pre-school children will be increased. Children's playground represents a significant space of activity for pre-school children. Therefore, it is necessary to apply ergonomic principles which contribute to the adjustment of the playground elements to children's anatomic features. Based on the results presented in this paper, new constructions were designed and new playgrounds were installed in Serbia. Participants were children from three pre-school age groups: Junior age group (3-4 years of age, 17 children), Medium age group (4-5 years of age, 22 children), and Senior age group (5-6 years of age, 26 children). Thirty-one static anthropometric measures (12 in standing position, 11 in sitting position, 7 related to dimensions of hand, foot an head, with body weight and shoe size) and 15 dynamic anthropometric measures (7 in standing position, 6 in sitting position and 2 dimension of foot and hand) were defined for the study. Measurements were taken using an anthrop-meter, a flexible measuring tape. Equations for ergonomic design of children's playground elements were also defined. Basic statistical data of static and dynamic anthropometric measurements of the pre-school children are presented in this paper, as well as the statistical calculation of the corrective anthropometric measurements. Measurements were performed in "Poletarac" kindergarten, part of the pre-school institution "Radost" in Cacak. Elements of playground equipment in "Bambi" kindergarten in Kragujevac (the Indian tent "wigwam", gate-house, swing and carousel) were designed and built using these parameters.

2011-01-01

This study contributes to ongoing scholarship at the nexus of translational research, education reform, and the developmental and prevention sciences. It reports 2-year experimental impacts of a universal, integrated school-based intervention in social-emotional learning and literacy development on children's social-emotional, behavioral, and academic functioning. The study employed a school-randomized, experimental design with 1,184 children in 18 elementary schools. Children in the intervention schools showed improvements across several domains: self-reports of hostile attributional bias, aggressive interpersonal negotiation strategies, and depression, and teacher reports of attention skills, and aggressive and socially competent behavior. In addition, there were effects of the intervention on children's math and reading achievement for those identified by teachers at baseline at highest behavioral risk. These findings are interpreted in light of developmental cascades theory and lend support to the value of universal, integrated interventions in the elementary school period for promoting children's social-emotional and academic skills. © 2011 The Authors.

Schools provide a natural context to promote children's mental health. However, there is a need for more evidence-based, high quality school intervention programs combined with an accurate evaluation of their general effectiveness and effectiveness of specific intervention methods. The aim of this paper is to present a study protocol of a cluster randomized controlled trial evaluating the "Together at School" intervention program. The intervention program is designed to promote social-emotional skills and mental health by utilizing whole-school approach and focuses on classroom curriculum, work environment of school staff, and parent-teacher collaboration methods. The evaluation study examines the effects of the intervention on children's socio-emotional skills and mental health in a cluster randomized controlled trial design with 1) an intervention group and 2) an active control group. Altogether 79 primary school participated at baseline. A multi-informant setting involves the children themselves, their parents, and teachers. The primary outcomes are measured using parent and teacher ratings of children's socio-emotional skills and psychological problems measured by the Strengths and Difficulties Questionnaire and the Multisource Assessment of Social Competence Scale. Secondary outcomes for the children include emotional understanding, altruistic behavior, and executive functions (e.g. working memory, planning, and inhibition). Secondary outcomes for the teachers include ratings of e.g. school environment, teaching style and well-being. Secondary outcomes for both teachers and parents include e.g. emotional self-efficacy, child rearing practices, and teacher-parent collaboration. The data was collected at baseline (autumn 2013), 6 months after baseline, and will be collected also 18 months after baseline from the same participants. This study protocol outlines a trial which aims to add to the current state of intervention programs by presenting and studying a

The study aimed to conduct an ergonomic intervention on a conventional line (CL) in a semiconductor factory in Malaysia, an industrially developing country (IDC), to improve workers' occupational health and safety (OHS). Low-cost and simple (LCS) ergonomics methods were used (suitable for IDCs), e.g., subjective assessment, direct observation, use of archival data and assessment of noise. It was found that workers were facing noise irritation, neck and back pains and headache in the various processes in the CL. LCS ergonomic interventions to rectify the problems included installing noise insulating covers, providing earplugs, installing elevated platforms, slanting visual display terminals and installing extra exhaust fans. The interventions cost less than 3 000 USD but they significantly improved workers' OHS, which directly correlated with an improvement in working conditions and job satisfaction. The findings are useful in solving OHS problems in electronics industries in IDCs as they share similar manufacturing processes, problems and limitations.

The role of travel mode in engagement with a Radio Frequency ID chip based school physical activity intervention

Directory of Open Access Journals (Sweden)

Emma Coombes

2015-10-01

Full Text Available Background: The prevalence of active travel to school in children is low and declining. For example, the 2014 National Travel Survey showed that just 46% of primary school children walk to school. This is despite the fact that children who actively travel have been shown to be more physically active overall as well as perform better in class. Beat the Street is a community based intervention which uses RFID (Radio Frequency ID chip readers attached to locations around the neighbourhood. The aim of the intervention is to encourage walking and cycling by gamifying these travel behaviours; individuals taking part gain points by touching a smartcard on the readers and these points become part of a competition. One of the aims of Beat the Street is to encourage children who already walk and cycle to and from school to do so more, as well as achieve modal shift from motorised transport to active travel as a means of commuting. However, habitual travel mode is ‘sticky’ and, despite the potential health benefits being greater, it may be more difficult to change mode than it is to encourage more activity in those who already walk or cycle. Set in a neighbourhood in the city of Norwich, England, this analysis examines how travel mode prior to the initiation of Beat the Street is associated with subsequent engagement with the intervention and what the association of this engagement is with physical activity change. Aim: This pilot study evaluates how prior travel mode to school is associated with engagement in the Beat the Street intervention in schoolchildren in the city of Norwich, England. Methods: The Beat the Street intervention was conducted within a Norwich neighbourhood for 9 weeks during May-July 2014. Children were recruited to the evaluation via two schools; one in the intervention neighbourhood, and a control located on the opposite side of the city. All year 4 and 5 children (aged 8-10 years were invited at both schools. Recruited children

Defining man-machine cooperation within complex systems: an ergonomic view of automation

International Nuclear Information System (INIS)

Lagrange, V.; Cara, F.

1997-01-01

Faced with the question of the optimal automation level in the operations of complex systems, ergonomists offer designers procedures, methods and criteria to take human factors into account. These means have been elaborated in the course of ergonomic interventions in projects at EDF. Based on knowledge of the operators' effective role they attempt to define, among the solutions that are technically possible, those that are desirable from the perspective of the whole man-machine system.

Full Text Available Abstract Background Improving nutrition knowledge among children may help them to make healthier food choices. The aim of this study was to assess the effectiveness and acceptability of a novel educational intervention to increase nutrition knowledge among primary school children. Methods We developed a card game 'Top Grub' and a 'healthy eating' curriculum for use in primary schools. Thirty-eight state primary schools comprising 2519 children in years 5 and 6 (aged 9-11 years were recruited in a pragmatic cluster randomised controlled trial. The main outcome measures were change in nutrition knowledge scores, attitudes to healthy eating and acceptability of the intervention by children and teachers. Results Twelve intervention and 13 control schools (comprising 1133 children completed the trial. The main reason for non-completion was time pressure of the school curriculum. Mean total nutrition knowledge score increased by 1.1 in intervention (baseline to follow-up: 28.3 to 29.2 and 0.3 in control schools (27.3 to 27.6. Total nutrition knowledge score at follow-up, adjusted for baseline score, deprivation, and school size, was higher in intervention than in control schools (mean difference = 1.1; 95% CI: 0.05 to 2.16; p = 0.042. At follow-up, more children in the intervention schools said they 'are currently eating a healthy diet' (39.6% or 'would try to eat a healthy diet' (35.7% than in control schools (34.4% and 31.7% respectively; chi-square test p Conclusions The 'Top Grub' card game facilitated the enjoyable delivery of nutrition education in a sample of UK primary school age children. Further studies should determine whether improvements in nutrition knowledge are sustained and lead to changes in dietary behaviour.

2014-01-01

Given that lifestyleshave similar determinants and that school-based interventions are usually targeted at all the risks that affect adolescents, the objective of this systematic review was to summarize the characteristics and effects of school-based interventions acting on different behavioral domains of adolescent health promotion. The review process was conducted by two independent reviewers who searched PubMed, Scopus, PsycINFO, and ERIC databases for experimental or observational studies with at least two measures of results published from 2007 to 2011, given that the research information available doubles every 5 years. Methodological quality was assessed with a standardized tool. Information was extracted from 35 studies aiming to prevent risk behaviors and promote healthy nutrition, physical activity, and mental and holistic health. Activities were based on theoretical models and were classified into interactive lessons, peer mediation, environmental changes, parents' and community activities, and tailored messages by computer-assisted training or other resources, usually including multiple components. In some cases, we identified some moderate to large, short- and long-term effects on behavioral and intermediate variable. This exhaustive review found that well-implemented interventions can promote adolescent health. These findings are consistent with recent reviews. Implications for practice, public health, and research are discussed. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

Mathiassen, Svend Erik; Larsson, Johan; Kwak, Lydia

2018-01-01

Objective To conduct a process evaluation of the implementation of an ergonomics training program aimed at increasing the use of loading assist devices in flight baggage handling. Methods Feasibility related to the process items recruitment, reach, context, dose delivered (training time and content); dose received (participants’ engagement); satisfaction with training; intermediate outcomes (skills, confidence and behaviors); and barriers and facilitators of the training intervention were assessed by qualitative and quantitative methods. Results Implementation proved successful regarding dose delivered, dose received and satisfaction. Confidence among participants in the training program in using and talking about devices, observed use of devices among colleagues, and internal feedback on work behavior increased significantly (p<0.01). Main facilitators were self-efficacy, motivation, and perceived utility of training among the trainees. Barriers included lack of peer support, opportunities to observe and practice behaviors, and follow-up activities; as well as staff reduction and job insecurity. Conclusions In identifying important barriers and facilitators for a successful outcome, this study can help supporting the effectiveness of future interventions. Our results suggest that barriers caused by organizational changes may likely be alleviated by recruiting motivated trainees and securing strong organizational support for the implementation.

¿Puede hablarse de transferencia de modelos de investigación/herramientas de intervención en ergonomía?

Directory of Open Access Journals (Sweden)

Abada Mhamdi

2013-12-01

Full Text Available Several experiences in Tunisian companies show that the tool or methods in ergonomics intervention must be built in loco. Each intervention is a typical case and many contributions of ergonomics or clinical analysis of activity have given the theoretical bases and explanations. It's exceptional that a method developed in a company can be transferred (applied as it is elsewhere. However, how far can the transfer of theoretical and methodological models be applied? Up to what point can the approach take into account a particular work environment, the specific organization of the company and the culture of a country on risk perception, while safeguarding guidelines and principles considered essential? Building common ground between the company and research is expected to give local sustainability in this type of debate.

Morag, Ido; Luria, Gil

2013-01-01

Despite the unanimity among researchers about the centrality of workplace analysis based on participatory ergonomics (PE) as a basis for preventive interventions, there is still little agreement about the necessary of a theoretical framework for providing practical guidance. In an effort to develop a conceptual PE framework, the authors, focusing on 20 studies, found five primary dimensions for characterising an analytical structure: (1) extent of workforce involvement; (2) analysis duration; (3) diversity of reporter role types; (4) scope of analysis and (5) supportive information system for analysis management. An ergonomics analysis carried out in a chemical manufacturing plant serves as a case study for evaluating the proposed framework. The study simultaneously demonstrates the five dimensions and evaluates their feasibility. The study showed that managerial leadership was fundamental to the successful implementation of the analysis; that all job holders should participate in analysing their own workplace and simplified reporting methods contributed to a desirable outcome. This paper seeks to clarify the scope of workplace ergonomics analysis by offering a theoretical and structured framework for providing practical advice and guidance. Essential to successfully implementing the analytical framework are managerial involvement, participation of all job holders and simplified reporting methods.

30 years of ergonomics at 3M: a case study.

Science.gov (United States)

Larson, N; Wick, H

2012-01-01

The added value of the Ergonomics Program at 3M was found to be improved employee safety, compliance with regulations and reduction of work-related illness, increases in productivity, and quality and operating efficiency. This paper describes the thirty years of existence of this program. For the first twenty years, the program objectives were to: respond to requests for assistance related to work-related musculoskeletal disorder (WMSD) concerns, raise employee awareness of MSDs and ergonomics; educate engineers in ergonomics design; and develop ergonomics teams at manufacturing locations. Since the year 2000, 3M's Ergonomics Program has been in transition from a US-centric and corporate-based technical-expertled program to a global program applying participatory ergonomics strategies within a macroergonomics framework. During that transition, the existing program requirements were revised, new methods and program tools were created, and expectations for implementation at the manufacturing locations clarified. This paper focuses on the company's manufacturing ergonomics program activities during the past ten years and includes specifics of the program's objectives, risk assessment reduction process, and ergonomics technical expertise development. The main benefit achieved throughout the company is reducing employee injury while also increasing productivity and operating efficiency.

Depression can have devastating effects unless prevented or treated early and effectively. Schools offer an excellent opportunity to intervene with adolescents presenting emotional problems. There are very few universal school-based depression interventions conducted in low- and middle-income countries. To assess the effectiveness of a school-based, universal psychological intervention to reduce depressive symptoms among adolescents from low-income families. A 2-arm, parallel, cluster, randomized clinical trial was conducted in secondary schools in deprived socioeconomic areas of Santiago, Chile. Almost all students registered in the selected schools consented to take part in the study. A total of 2512 secondary school students from 22 schools and 66 classes participated. Students in the intervention arm attended 11 one-hour weekly and 2 booster classroom sessions of an intervention based on cognitive-behavioral models. The intervention was delivered by trained nonspecialists. Schools in the control arm received the standard school curriculum. Scores on the self-administered Beck Depression Inventory-II at 3 months (primary) and 12 months (secondary) after completing the intervention. There were 1291 participants in the control arm and 1221 in the intervention arm. Primary outcome data were available for 82.1% of the participants. There was no evidence of any clinically important difference in mean depression scores between the groups (adjusted difference in mean, -0.19; 95% CI, -1.22 to 0.84) or for any of the other outcomes 3 months after completion of the intervention. No significant differences were found in any of the outcomes at 12 months. A well-designed and implemented school-based intervention did not reduce depressive symptoms among socioeconomically deprived adolescents in Santiago, Chile. There is growing evidence that universal school interventions may not be sufficiently effective to reduce or prevent depressive symptoms. isrctn.org Identifier: ISRCTN

Use of laptops and hand-held devices increase the risk of musculoskeletal disorders (MSDs). More time spent on this activity adopting faulty postures, higher the risk of developing such injuries. This study addresses training on office ergonomics with emphasis on sustainable behavior change among employees to work in safe postures, as this is a top priority in the corporate environment, today. To explore training intervention methods that ensure wider coverage of awareness on office ergonomics, thereby promoting safer working and suggesting sustainable programs for behavior change and job enrichment. A cross-sectional study was conducted (2012 - 2017), encompassing corporate office employees of multinational corporations selected from India, Dubai (U.A.E), Nairobi (East Africa), Durban (South Africa), South East Asian countries (Philippines, Vietnam, Indonesia, Singapore, Malaysia, Thailand and Sri Lanka).Participant employees ( n = 3503) were divided into two groups to study the effect of interventions'; i.e., (a) deep training: 40 minute lecture by the investigator with a power point presentation ( n = 1765) using a mock workstation and (b) quick training: live demonstrations of 10 minutes ( n = 1738) using a live workstation. While deep training enhanced awareness in 95.51% and quick training in 96.59% globally, the latterwas much appreciated and educated maximum employees. From statistical analysis, quick training was found superior in providing comprehensive training and influencing behavior modification in India, but all over the world it was found highly superior in knowledge enlargement, skills enrichment in addition to providing comprehensive training ( P office ergonomics program. This could lead to propose as a best practice for corporate offices globally.

The aim of this study was to qualitatively evaluate the experiences of students enrolled in the last year of dentistry school with ergonomic practice. This is a qualitative, observational and cross-sectional study, with a non-probabilistic sample design. The sample comprised students enrolled in the last year of dentistry in Araraquara-UNESP (n = 29). The data were collected by means of open semi-structured and individual interviews, captured by a digital voice recorder. The students were interviewed in their own university at a time that was previously scheduled, and care was taken to provide a private and welcoming environment to carry out the interviews. A script containing questions related to practices in ergonomics was prepared at the university. Data analysis was carried out using the qualitative-quantitative Collective Subject Discourse technique with the aid of Qualiquantisoft ® software program. It was found that more than half of the students (58.6%) believe that adopting an ergonomic posture is important to prevent future problems, pain and occupational diseases, and 62.1% of the students confirm having difficulties in adopting ergonomic postures due to the types of treatment required and the regions of the mouth being treated. The main reasons stated for the fact that their colleagues do not adopt ergonomic postures are lack of attention, practice and forgetfulness (44.8%) and difficulty in visualising the operatory field or the procedure performed (27.6%). It is possible to conclude that the students interviewed know ergonomic principles and their importance in occupational health. However, they found it difficult to put these principles into practice. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

School-based interventions for increasing physical activity among children are widespread, however there is still a lack of knowledge about how school context factors are linked to implementation quality and effectiveness of programmes. The aim of this paper is to examine teacher-perceived effectiveness of a Danish national classroom-based health programme 'Active Around Denmark' and in particular, to investigate whether perceptions vary as a function of school social context factors. After completion of the programme all teachers (N = 5.892) received an electronic questionnaire. 2.097 completed the questionnaire (response rate 36%) and 1.781 datasets could be used for analysis. The teachers were asked about their perceptions of changes in children's attitudes towards and levels of physical activity after the competition. Our results indicated that certain contextual factors, such as schools' prioritization of health promotion, teachers' support by their school principal in implementation as well as teacher's satisfaction with the school' physical environment made a significant difference in teacher-perceived effectiveness. To conclude, teacher-perceived effectiveness of the health programme does vary as a function of school social context factors.

Formative assessment through an adaptive community-based participatory research (CBPR approach was conducted toward the development of a nutritional and physical activity (DVD and clinician toolkit for a school-based health center (SBHC weight management intervention. Methods. We first conducted parent and adolescent interviews on views and experiences about obesity while convening a community advisory council (CAC recruited from two participating urban New Mexico high schools. Thematic findings from the interviews were analyzed with the CAC to develop culturally and developmentally appropriate intervention materials. Results. Themes from the parent and adolescent interviews included general barriers/challenges, factors influencing motivation, and change facilitators. The CAC and university-based research team reached consensus on the final content of nutrition and physical activity topics to produce a DVD and clinician toolkit through six monthly sessions. These materials used in the SBHC intervention resulted in a greater reduction of body mass index when compared to adolescents receiving standard care. Conclusions. Formative assessment using an adaptive CBPR approach resulted in the creation of culturally and age appropriate weight reduction materials that were acceptable to study participants. This trial is registered with ClinicalTrials.gov NCT00841334.

Background Work-related musculoskeletal disorders are one of the main occupational health hazards affecting dental practitioners. This study was conducted to assess the prevalence of Work-related Musculoskeletal Disorder (WMSD) amongst dental students. Possible correlations with the working environment and ergonomics taught in Malaysian dental schools were also sought. Methods Five dental schools in Malaysia participated in this cross-sectional study. A validated self-administered questionnaire was used to establish the point prevalence of WMSD in the dental students based on various body regions. The questionnaire also collected data regarding the working environment, clinical practice and the taught ergonomics of the students during their training years. Results Out of five hundred and sixty eight dental students who participated in the study, 410 were in their clinical years whilst 158 were students in their non- clinical years. Ninety three percent of the clinical year students reported symptoms of WMSD in one or more body regions. Female students reported a significantly higher numbers of symptoms compared to male students. The neck (82%) and lower back (64%) were reported to have the highest prevalence of WMSD. Discomfort in the neck region was found to be associated with self-reported frequency of bending of the neck. A majority of students (92%) reported minimum participation in workshops related to ergonomics in dentistry and 77% were unfamiliar with treatment and remedies available in the case of WMSD. Conclusions There was more WMSD seen in dental students who had started their clinical years. Neck and lower back are more injury prone areas and are at increased risk of developing musculoskeletal disorders. Theory and practice of ergonomics should be incorporated into the dental undergraduate curriculum. PMID:23547959

Full Text Available Background Prevalence of low back pain (LBP and neck pain (NP in workers, especially in nurses is high, but their knowledge of ergonomics is not enough. Objectives The aim of this study was to evaluate the impact of ergonomic training on low back pain and neck pain, posture, and function in female hospital personnel of Najaf-Abad, Iran. Patients and Methods In this queasy experimental study, 47 female staffs with LBP or NP were selected through a simple consecutive sampling method. The subjects completed a questionnaire on LBP and NP and were evaluated for posture, back tests, and cost of related treatments. Afterward, they participated in an ergonomic training program, including face to face and group education sessions on ergonomic risk factors for LBP and NP, in the work place. After six months of follow up, all the tests and data collection were repeated and data was analyzed using paired t-test and regression analysis. Results Prevalence of LBP and NP were 87% and 45.7%, respectively. Repetitive motions were the most frequent cause of pain (67%. Pain intensity, posture, risk of musculoskeletal disorders, weight, waist circumference, sick leaves, and the costs of treatments reduced significantly after intervention (P < 0.05. Conclusions With regards to the influence of ergonomic training on improving LBP and NP and decreasing the treatment costs, this intervention beside others can be useful for controlling musculoskeletal disorders in hospital personnel.

Failure to adopt a correct working posture can lead to occupational diseases. Evaluate knowledge in relation to ergonomics about BHOP concept and its application to routine clinical practice amongst undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain). A study based on interviews of undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain) was carried out. The information from a total of 336 interviews was used for the statistical analysis, differentiating according to gender and academic year: knowledge of ergonomics, pain prevalence and antecedents, assessment of the possible necessity for improved training in ergonomics, and evaluation of postural hygiene. Only 28.6% of the students were found to sit correctly in the dentist chair. Furthermore, in the opinion of the students, very few subjects during the career afforded adequate teaching in relation to ergonomics and working posture. The analysis of postural hygiene showed great variability. There were no significant differences in posture between males and females, although some incorrect postures appeared to be associated with the academic year (Ppostural hygiene were noted on progressing from one academic year to the next. The students in our study were not familiar with the principles of ergonomics and did not sit correctly in the dentist chair. Improved training in this field is required in dental school. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The HEALTHY primary prevention trial developed an integrated multicomponent intervention program to moderate risk factors for type 2 diabetes in middle schools. The nutrition component aimed to improve the quality of foods and beverages served to students. Changes in the School Breakfast Program (SBP), National School Lunch Program (NSLP), and à la carte venues are compared to the experience of control schools. The intervention was implemented in 21 middle schools from winter 2007 through spring 2009 (following a cohort of students from sixth through eighth grades); 21 schools acted as observed controls. The nutrition component targeted school food service environmental change. Data identifying foods and nutrients served (selected by students for consumption) were collected over a 20-day period at baseline and end of study. Analysis compared end of study values for intervention versus control schools. Intervention schools more successfully limited dessert and snack food portion size in NSLP and à la carte and lowered fat content of foods served. Servings of high-fiber grain-based foods and/or legumes were improved in SBP but not NSLP. Intervention and control schools eliminated >1% fat milk and added-sugar beverages in SBP, but intervention schools were more successful in NSLP and à la carte. The HEALTHY program demonstrated significant changes in the nutritional quality of foods and beverages served in the SBP, NSLP, and à la carte venues, as part of an effort to decrease childhood obesity and support beneficial effects in some secondary HEALTHY study outcomes.

Full Text Available School-based mindfulness interventions have been shown to be effective in reducing mental health symptoms. However, comparatively little research has investigated the acceptability of these programs from the perspective of the children. Program acceptability underpins engagement, and more engaging programs are also more efficacious (Cowan & Sheridan, 2003; Mautone et al., 2009 yet there is little literature which has considered the acceptability of school-based mindfulness programs. To address this gap, semi-structured interviews were conducted with upper primary aged children (N = 30 who had participated in a six week mindfulness program in four Australian primary schools. Thematic analysis of interviews revealed children found the program to be acceptable. Children reported that they enjoyed doing the mindfulness program, would recommend it to others, and learned about relaxing as well as felt relaxed while doing the program. Children also highlighted the use of culturally appropriate teaching materials and possible stigmatisation as threats to the acceptability of the program. The results of the study support the acceptability of mindfulness programs in school settings, grounded in the unique perspective of the child.

This 16-month randomized, controlled school-based study compared change in tibial bone strength between 281 boys and girls participating in a daily program of physical activity (Action Schools! BC) and 129 same-sex controls. The simple, pragmatic intervention increased distal tibia bone strength in prepubertal boys; it had no effect in early pubertal boys or pre or early pubertal girls. Numerous school-based exercise interventions have proven effective for enhancing BMC, but none have used pQCT to evaluate the effects of increased loading on bone strength during growth. Thus, our aim was to determine whether a daily program of physical activity, Action Schools! BC (AS! BC) would improve tibial bone strength in boys and girls who were pre- (Tanner stage 1) or early pubertal (Tanner stage 2 or 3) at baseline. Ten schools were randomized to intervention (INT, 7 schools) or control (CON, 3 schools). The bone-loading component of AS! BC included a daily jumping program (Bounce at the Bell) plus 15 minutes/day of classroom physical activity in addition to regular physical education. We used pQCT to compare 16-month change in bone strength index (BSI, mg2/mm4) at the distal tibia (8% site) and polar strength strain index (SSIp, mm3) at the tibial midshaft (50% site) in 281 boys and girls participating in AS! BC and 129 same-sex controls. We used a linear mixed effects model to analyze our data. Children were 10.2+/-0.6 years at baseline. Intervention boys tended to have a greater increase in BSI (+774.6 mg2/mm4; 95% CI: 672.7, 876.4) than CON boys (+650.9 mg2/mm4; 95% CI: 496.4, 805.4), but the difference was only significant in prepubertal boys (p=0.03 for group x maturity interaction). Intervention boys also tended to have a greater increase in SSIp (+198.6 mm3; 95% CI: 182.9, 214.3) than CON boys (+177.1 mm3; 95% CI: 153.5, 200.7). Change in BSI and SSIp was similar between CON and INT girls. Our findings suggest that a simple, pragmatic program of daily activity

Assessment of ergonomic strain during robotic surgery indicates there is a need for intervention. However, limited data exist detailing the feasibility and acceptance of ergonomic training (ET) for robotic surgeons. This prospective, observational pilot study evaluates the implementation of an evidence-based ET module. A two-part survey was conducted. The first survey assessed robotic strain using the Nordic Musculoskeletal Questionnaire (NMQ). Participants were given the option to participate in either an online or an in-person ET session. The ET was derived from Occupational Safety and Health Administration guidelines and developed by a human factors engineer experienced with health care ergonomics. After ET, a follow-up survey including the NMQ and an assessment of the ET were completed. The survey was sent to 67 robotic surgeons. Forty-two (62.7%) responded, including 18 residents, 8 fellows, and 16 attending physicians. Forty-five percent experienced strain resulting from performing robotic surgery and 26.3% reported persistent strain. Only 16.6% of surgeons reported prior ET in robotic surgery. Thirty-five (78%) surgeons elected to have in-person ET, which was successfully arranged for 32 surgeons (91.4%). Thirty-seven surgeons (88.1%) completed the follow-up survey. All surgeons participating in the in-person ET found it helpful and felt formal ET should be standard, 88% changed their practice as a result of the training, and 74% of those reporting strain noticed a decrease after their ET. Thus, at a high-volume robotics center, evidence-based ET was easily implemented, well-received, changed some surgeons' practice, and decreased self-reported strain related to robotic surgery.

Full Text Available Abstract Background Physical activity levels decline markedly among girls during adolescence. School-based interventions that are multi-component in nature, simultaneously targeting curricular, school environment and policy, and community links, are a promising approach for promoting physical activity. This report describes the rationale, design and baseline data from the Girls in Sport group randomised trial, which aims to prevent the decline in moderate-to-vigorous intensity physical activity (MVPA among adolescent girls. Methods/Design A community-based participatory research approach and action learning framework are used with measurements at baseline and 18-month follow-up. Within each intervention school, a committee develops an action plan aimed at meeting the primary objective (preventing the decline in accelerometer-derived MVPA. Academic partners and the State Department of Education and Training act as critical friends. Control schools continue with their usual school programming. 24 schools were matched then randomized into intervention (n = 12 and control (n = 12 groups. A total of 1518 girls (771 intervention and 747 control completed baseline assessments (86% response rate. Useable accelerometer data (≥10 hrs/day on at least 3 days were obtained from 79% of this sample (n = 1199.

Children with ADHD typically show impairments throughout the school day. A number of interventions have been demonstrated to address both the academic and behavioral impairments associated with this disorder. Although the focus of research has been on classroom-based strategies of intervention for children with ADHD, school-based interventions applicable for non-classroom environments such as lunchrooms and playgrounds are beginning to emerge. This paper provides a brief description of the guiding principles of behavioral intervention, identifies selected strategies to address behavioral and academic concerns, discusses how school contextual factors have an effect on intervention selection and implementation, and considers the effects of using psychosocial interventions in combination with medication.

Full Text Available The most important environmental factor affecting human health is the long exposure to solar ultraviolet radiation. This study aimed to determine the effect of an educational intervention based on the protection motivation theory in promoting sun-protective behaviors. In this quasi-experimental prepost test study, a sample of 215 high school students in Ahwaz. Using a reliable and valid questionnaire, and based on the theory of protection motivation, the data were collected before and four months after the intervention. In the posttest, there was a significant difference in mean score of the protection motivation theory components between the experimental and control groups. the comparison of the mean score of the components of protection motivation theory in the experimental and control groups before and after the intervention showed a significant difference in all the components except for the response cost, while in the control group the mean score difference not significant. The results of this study showed that the intervention may lead to the sun exposure preventive behaviors, which reflects the effectiveness of the educational intervention based on the protection motivation theory.

Although the science of ergonomics did not actually emerge until the 20th century, there is evidence to suggest that ergonomic principles were in fact known and adhered to 25 centuries ago. The study reported here is a first attempt to research the ergonomics concerns of ancient Greeks, on both a conceptual and a practical level. On the former we present a collection of literature references to the concepts of usability and human-centred design. On the latter, examples of ergonomic design from a variety of fields are analysed. The fields explored here include the design of everyday utensils, the sculpture and manipulation of marble as a building material and the design of theatres. Though hardly exhaustive, these examples serve to demonstrate that the ergonomics principles, in content if not in name, actually emerged a lot earlier than is traditionally thought.

The sustainability of the workforce is threatened due to working conditions. One of the reasons for this is an imbalance between the working conditions and the capacity of the workers. The objective of the paper, based on a literature review, is to explore the relationship between two main concepts, beginning with sustainability, and finished with ergonomics. Based on that relationship, determine if ergonomics could be helpful to improve the sustainability of the workforce. Literature review was based on two keywords: sustainability and ergonomics. The focus was on create a theoretical path between these two concepts. The literature review draws on 100 journal articles, books, conference proceedings, thesis and reports. The results of the literature review highlights that an ergonomics approach is helpful and appropriate to determine the mismatch between people capacity and system demand. In that sense, the literature review reveals that both disciplines, ergonomics and sustainability, share the same principles and that the mix of both has significant potential. However, the literature also shows a lack of empirical information that proves that potential. The review first posits that sustainability principles could be helpful to improve the working conditions, and second, that an ergonomics approach provides information related with working conditions, organizations' problems and the needs of workers that would be helpful to create a sustainability workforce.

Full Text Available Background: Bullying perpetration and victimization is associated with significant academic, psychosocial and health related problems among adolescents. There is a need to develop effective interventions to prevent bullying among adolescents, especially in low and middle income countries. This paper presents the study protocol to develop, and evaluate the effect of multi-component school based prevention program for bullying in India. Design: Quasi-experimental study. Methods: The study will be conducted among 846 students of grade 7th and 8th in the intervention and control schools in Chandigarh, Union Territory, North India. A government and a private school will be selected purposively in each of the intervention and control arm. The intervention is based on socio-ecological model, and will be administered at individual, relationship (parents and teachers and school level. The primary study outcome will be the proportion of students experiencing any kind of bullying (bullying, victimization, or both, in each study arm. The effectiveness of the intervention will be measured by performing difference in difference analysis and generalized estimating equations. Expected impact for public health: Bullying is an aggressive behaviour with significant morbidities, including psychological or physical trauma, affecting individuals not only in their adolescence, but also later in their adulthood. This quasi-experimental study is expected to provide evidence on whether multi-component bullying prevention intervention program, can reduce the burden of bullying perpetration and victimization among school adolescents in India. The results of the study will add in the exiting literature on bullying intervention program, especially, from the low middle-income countries, as there are limited studies available on this topic in these countries.

This study examined the impact of an adaptive approach to family intervention in public schools on academic outcomes from age 11 to 17. Students were randomly assigned to the three-session Family Check-Up (FCU), which is designed to motivate change in parenting practices by using an assessment-driven approach and strengths-based feedback. All services were voluntary, and approximately 25% of the families engaged in the FCU. Compared with matched controls, adolescents whose parents received the FCU maintained a satisfactory GPA into high school, and intervention engagement was associated with improved attendance. The highest-risk families were the most likely to engage in the family-centered intervention, suggesting the efficacy of integrating supportive services to families in the context of other schoolwide approaches to promote the success and achievement of vulnerable students.

2012-01-01

Background The current academic literature suggests there is a potential for using gardening as a tool to improve children’s fruit and vegetable intake. This study is two parallel randomised controlled trials (RCT) devised to evaluate the school gardening programme of the Royal Horticultural Society (RHS) Campaign for School Gardening, to determine if it has an effect on children’s fruit and vegetable intake. Method/Design Trial One will consist of 26 schools; these schools will be randomised into two groups, one to receive the intensive intervention as “Partner Schools” and the other to receive the less intensive intervention as “Associate Schools”. Trial Two will consist of 32 schools; these schools will be randomised into either the less intensive intervention “Associate Schools” or a comparison group with delayed intervention. Baseline data collection will be collected using a 24-hour food diary (CADET) to collect data on dietary intake and a questionnaire exploring children’s knowledge and attitudes towards fruit and vegetables. A process measures questionnaire will be used to assess each school’s gardening activities. Discussion The results from these trials will provide information on the impact of the RHS Campaign for School Gardening on children’s fruit and vegetable intake. The evaluation will provide valuable information for designing future research in primary school children’s diets and school based interventions. Trial registration ISRCTN11396528 PMID:22537179
