- Factors influencing workplace physical activity interventions: a short reviewPublication . Maheronnaghsh, Sara; Santos, Joana; Vaz, MárioIntroduction: Many occupations are characterized by sedentary behavior (SB) and lack of physical activity (PA). There is growing evidence that prolonged sitting is associated with multiple health risks, including musculoskeletal disorders, biomarkers of increased cardiovascular diseases, some forms of cancer. There is an increasing interest in changing the work environment by implementing various interventions to reduce barriers and promote physical activity. The aim of this short review is to identify factors that affected workers’ SB and/or PA to design appropriate interventions. Methodology The search was performed based on PRISMA statement methodology and was conducted in Scopus for articles and reviews published in scientific journals from 2010 until 2019 in English, usinga set of root keywords as “sedentary work,” “physical activity” and ”effectiveness intervention”. Results and discussion the review included 12 studies describing effective factors on PA in three categories: organizational factor, individual factor, and social factor. The main organizational factors found were: supportive workplace policies and resources, time for involvement in intervention, paying for activity, management support, work environment factors, and job type (passive jobs, and high-strain jobs). Interpersonal factors, knowledge include (educational level and information about physical activity guidelines) and some sociodemographic factors as individual factors associated with the physical work activity. Furthermore, social factors like social support and social norm have a significant effect on willing to do physical activity in workers. Some studies used “behavior change techniques” to find effective factors on physical activity for identifying the most appropriate interventions. Conclusion: Current evidence demonstrates that some individual, organizational and social factors influence work physical activity; therefore, they need to be considered in each population specifically, before choosing the intervention type. It can contribute to the increasing effectiveness of interventions intended to improve physical activity. Future research in this area should consider the association of various factors identified to enhance the effectiveness of interventions.
- ARIA Project – Indoor air biological assessment in primary schoolsPublication . Aguiar, Lívia; Pereira, Cristiana; Mendes, Ana; Neves, Paula; Teixeira, João PauloChildren are considered a susceptible group due to their particularly vulnerability to the development of respiratory diseases, such as asthma, and also the amount of time they spend inside classrooms, reasons why they deserve priority attention in indoor air quality studies.
- Níveis de iluminação em passadeiras: um estudo de casoPublication . Silva, N.; Sousa, R.; Rodrigues, MatildeA iluminação junto das passadeiras é considerada um dos principais fatores de risco associados à ocorrência de acidentes por atropelamento. O presente estudo teve como objetivo caracterizar a iluminação em passadeiras sem controlo de travessia por semáforo numa região do Norte do país. Neste estudo foram caracterizadas 27 passadeiras. Foram recolhidos os valores da iluminância vertical e horizontal médios. Os resultados mostraram que em todas as passadeiras caracterizadas os níveis de iluminância vertical médios se encontravam abaixo dos valores recomendados (>20lux). Em relação aos níveis de iluminação horizontal médios, parte das passadeiras apresentaram valores abaixo do recomendado (>20lux). As obstruções foram identificadas como um fator que poderá ter influenciado o nível de iluminação das passadeiras, assim como a distância das luminárias à passadeira e ainda o estado de conservação das mesmas. Os resultados sugerem a necessidade de uma maior manutenção dos sistemas de iluminação das passadeiras, bem como um reforço junto às zonas mais perigosas.
- The impact of work shift on psychosocial risks: a case studyPublication . Seixas, Andrea; Ferreira, Tânia; Vieira da Silva, Manuela; Rodrigues, MatildeThe present study aims to analyse the impact of the work shift in the prevalence of Burnout syndrome, anxiety, depression and stress. This study was conducted in a metal-mechanic industry, covering a total of 175 workers of the production sector, spread over three shifts (morning, afternoon and night). The Burnout syndrome was assessed by the Shirom-Melamed Burnout Measure and the anxiety, depression and stress were measured through the Depression Anxiety Stress Scales (DASS). Results showed that while workers experienced a low level of Burnout and stress, they were found to exhibit higher levels of anxiety and depression. Against expectations, morning shift presented higher levels of psychosocial risks. However, no significant differences were found between the three shifts. These results can be explained by several factors such the age of the workers, years of work or type of employment contract. This study emphasizes the need to implement measures to reduce workers' exposure in the morning shift.
- The influence of job rotation on wrist position sense: a preliminary study among assembly workers in a real-life occupational settingPublication . Santos, Joana; Mesquita, Inês; Monteiro, Pedro; Santos, Rubim; Baptista, João Santos; Vaz, MárioThe effectiveness of job rotation in industrial environment is still controversial, namely during tasks with high functional similarity, as assembly tasks. Thus, the aim of this study was to investigate the influence of job rotation on wrist position sense acuity among experienced assembly workers. Eight healthy assembly workers divided in two groups (four assembly workers performed task rotation and four assembly workers performed tasks with no rotation) participated in this field study. Manifestations of muscle fatigue of wrist flexors and extensors muscles were obtained by surface electromyography during a standardized test contraction, while wrist position sense errors were assessed by electrogoniometry. After a workweek, d espite not statistically significant, wrist flexors muscles in the no rotation group showed EMG signs of fatigue. The two groups showed a trend to increase position error for flexion after a workweek. Future research should include a higher number of participants and other techniques to evaluate muscle fatigue and their impact on positon sense acuity.
- Measurement of upper-limb joint angular kinematics: A comparative study in manual and semi-automated assembly linePublication . Abreu, Ana Betty; Santos, Joana; Baptista, JoãoAssembly lines are the production system mostly used in industry in order to achieve higher production rates. Thus, workstations are getting more automated and operators tend to perform highly dynamic repetitive movements. As the work demands increase the biomechanical load of the soft tissues of the upper-limbs are also intensified. The operator’s exposure to this work-related risk factor is a probable cause for the development of work-related musculoskeletal disorders. The main purpose of the study is to measure the range of motion of the upper-limb articulation of subjects in the same workstation in two different assembly lines when performing assemble work. For the data collection was used an inertial measurement system Xsens MVN BIOMECH. The data indicates that the operators have similar range of motion in the upper-limb articulation. It was possible to verify that the subjects in study perform repetitive movements and tend to adopt the work method defined.
- Manifestations of muscle fatigue during repetitive low-moderate intensity work: a brief reviewPublication . Santos, Joana; Monteiro, Pedro; Miguel, Alberto Sérgio; Santos, Rubim; Baptista, J. Santos; Vaz, MárioMuscle fatigue is a complex phenomenon that has been suggested to be an important precursor for work-related upperlimb musculoskeletal disorders. The assembly work is an example of low-moderate intensity work with elevated risk of muscle fatigue development. This review was performed to summarise and analyse the studies that investigated the influence of work requirements on muscle fatigue development in workplaces or experimental setting. This review was based on relevant articles published from 2000 to 2013 in the research platform Web of Knowledge. The studies included in this review were performed in humans and assess peripheral muscle fatigue in upper limbs during occupational activities. The search yielded 103 articles and 10 were included, according to inclusion criteria. Few studies were conducted in real work environment and the most common methods used to assess muscle fatigue were surface electromyography (EMG). The work duration and intensity level were the determinants of muscle fatigue that had more consistent results in terms of EMG- based parameters. In the studies that report subjective measurement of muscle fatigue, the subjective ratings increase. More research is needed to understand the impact of work requirements on muscle fatigue and work-related performance.
- NeoNoise Project: Preliminary results of sound pressure levels in a neonatal intensive care unitPublication . Santos, Joana; Carvalhais, Carlos; Nóia, Mara; Baptista, J. Santos; Vieira da Silva, ManuelaThe noise in the neonatal intensive care units (NICU) is recognized by many researchers as an agent with negative implications on health and well-being of premature infants and health professionals. The present study aimed to evaluate and analyse the sound pressure levels variations in a Portuguese NICU and the noise perception of health professionals and, consequently, propose control actions for noise reduction levels. The measurements of the equivalent continuous A-weighted sound pressure level (LAeq), took into account the layout of unit and location of the main sources of noise. A questionnaire was applied to assess noise perception of professionals. In general, the results are higher than the limit recommended by international organizations, ranged between 48.3 dB (A) and 82.5 dB (A). Routine activities were identified as potential source of noise levels. Significant differences has been found between the morning and night shift (p

Correia, Ana; Balazeiro, Márcia; Cavadas, Maria I.; Campos, Joana R.; Costa, Nelson; Rodrigues, João; Rodrigues, MatildeThis study aims to characterize the occupational accidents in convenience supermarkets, identifying the personal factors related to its frequency and severity. A total of 443 accidents that occurred between 2015 and September 2017, in a group of supermarkets from a Portuguese company, were analyzed. Different company databases were gathered and compiled for the purpose of this study. Frequency and severity rates were determined for the total accidents and for employees age and gender. Results showed that both accident rates increased during the analyzed period. Higher frequency and severity rates were found for female. Data also denote that accidents with higher severity occurred in workers with more than 46 years old and among the ones with basic education.
- Avaliação de riscos biológicos e implementação do plano de ação em laboratórios BSL3Publication . Neto, Flávio; Gomes Pereira, Sandra Isabel; Neto, Hernâni VelosoBiological risk assessment is an essential tool to trigger and develop appropriate protective measures, which are determined by the characteristics of the agents involved in the activity and by the adequacy of the facilities, equipment and work practices. The main purpose of this work was to evaluate and manage biological risks in biosafety level 3 (BSL3) facilities, as well the risk assessment and categorization in the activities developed in a research laboratory. The method selected was the MARAT (method of risk assessment and work accidents) and the biological agent under evaluation was Mycobacterium tuberculosis (Mtb), the bacteria responsible for human tuberculosis. The BSL3 laboratory and the research procedures were evaluated concerning the infrastructure (including equipment) and laboratory organization, good laboratory practice, decontamination procedures, emergency procedures in case of an incident /laboratory accident and transport of biological samples. The assessment study of biological risks and the development of an action plan in BSL3 contributes to the development of risk management and guarantees the safety and health of the workers exposed in these laboratories.
