Methodological considerations in the study of perceived discrimination at work and its association with workers health and occupational outcomes: A scoping review.

Introduction: Perceived workplace discrimination is a complex phenomenon involving unfair treatment in the workplace based on personal characteristics such as age, ethnicity, gender, or disability. The objective of this study is to explore the association of perceived workplace discrimination with health and occupational outcomes.

Methods: Following the PRISMA-ScR guidelines and the Joanna Briggs Institute methodology, a scoping review of articles published between 2000 and 2022 was conducted in databases such as Pubmed, Scopus, and PsyInfo.

A dimensional design of tractor seat based on Iranian anthropometric characteristics.

Background: The dimensional seat design process should consider both the users' tasks and their physical characteristics.

Objective: To use an approach for the design and evaluation of seat dimensions based on the anthropometric characteristics of the Iranian population and the requirements of tractor operators.

Methods: Some existing equations relating the seat dimensions to anthropometric characteristics were modified according to logical justifications and international standards.

Psychometric properties of the Iranian version of the wheelchair seating discomfort assessment tool (WcS-DAT) - section II: a revised two-dimensional structure of comfort and discomfort to improve inclusive design practice.

Purpose: The objectives of the study were to: 1) validate the Wheelchair Seating Discomfort Assessment Tool (WcS-DAT - section II) in Iran, and 2) to determine whether or not the items on the scale address just one dimension (e.g., discomfort).

Methodological considerations in the study of perceived discrimination at work: a scoping review protocol.

Introduction: Perceived discrimination is a complex phenomenon of study and has significant repercussions on people's health. Many studies confirm the negative effects of stress on workers' health in the workplace, affecting both their physical and mental health. However, there is no consensus when investigating the construct of "perceived work discrimination".

Head and facial dimensions of Chilean workers for design purposes and the differences with other populations.

Background: An appropriate match between a product and its end-users requires anthropometric data, which show variations among different countries. Proper Personal Protection Equipment (PPE) fit is key for safety and comfort. Chile had no head and facial anthropometric data available in order to design face/head PPE.

Developing countries and the use of ISO Standard 11228-3 for risk management of Work-Related Musculoskeletal Disorders of the Upper Limbs (WRMSDs-ULs): The case of Chile.

Work-Related Musculoskeletal Disorders of the Upper Limbs (WRMSDs-ULs) are one of the most common occupational diseases worldwide. Repetitive motion is one of the main risk factors associated with these conditions. Several efforts have been made within the scientific community in order to develop specific methods to assess the risk that repetitive work represents.

Perception of just culture and its association with work-related psychosocial factors in an Iranian industrial setting: Implications for prevention of errors.

Background: A just culture is one in which the reporting of errors and near misses is supported without fear of retribution. The relationship of just culture and psychosocial factors at work has not been explored sufficiently in the literature.

Objective: To investigate the perception of just culture and its association with socio-demographic and work-related psychosocial factors among 302 employees in an industrial setting in Iran.

Mismatch between jar opening demands and wrist torque strength of consumers in Iran.

This study evaluated the potential mismatch between vacuum-sealed jar opening demands and wrist torque strength of 758 (384 males and 374 females) participants aged 5-74 years in Iran. Wrist ulnar/radial (U/R) torque strength of participants and required torque for opening the existing jars (with 2 different sizes - 65 mm and 85 mm diameter lids) were measured using a digital angle torque adaptor and then compared together to identify any potential mismatch between them. The mismatch percentages were defined as the number of participants whose maximal wrist U/R torque strength were lower than the minimum required torque strength for opening the vacuum-sealed jars.

Application of mismatch equations in dynamic seating designs.

Anthropometry is critical for product and workplace design. Highly prevalent, office work is associated with sedentarism and physical discomfort due to prolonged sitting. Dynamic seating (alternating across sitting, perching, and standing) has been suggested as an alternative to overcome those problems.

Road traffic accidents of the elderly in Chile between the years 2008-2017: A register-based descriptive study.

Objective: To determine whether Chilean elderly persons have higher rates of traffic incidents, resulting in death or injury, compared to non-older adults between 2008 and 2017.

Method: The databases of the National Traffic Safety Commission of the last ten years and the data of inhabitants according to the projections made by the National Statistics Institute were used. Effect measures and 95% confidence intervals were calculated.

Do older workers suffer more workplace injuries? A systematic review.

Aging populations are a dramatically increased worldwide trend, both in developed and developing countries. This study examines the prevalence of fatal and non-fatal work-related injuries between young (<45 years old) and older (≥45 years old) workers. A systematic literature review aimed at examining studies comparing safety outcomes, namely fatal and non-fatal injuries, between older and younger workers.

Gender inequality and sexual height dimorphism in Chile.

Chile has experienced significant improvements in its economy; thus, a secular trend in height has been observed in its population. Gender equality has also improved hand in hand with active policies addressing the gender gap in several dimensions (work, education, health) and overall economic improvement. This study examined changes in sexual height dimorphism in four samples of Chilean male and female working-age subjects and attempted to establish associations with gender equality and welfare.

Educational level and its relationship with body height and popliteal height in Chilean male workers.

A secular trend in body height has been experienced in many nations and populations, hypothesized to be the result of better living conditions. Educational level has been shown to be closely associated with body height. This study examined the changes in body height and popliteal height in a group of adult Chilean male workers by age cohort and the relationship of these with educational level.

Effect of a posture correction-based intervention on musculoskeletal symptoms and fatigue among control room operators.

This study was conducted to examine the effect of a posture correction-based intervention (with a biofeedback device) on the occurrence of musculoskeletal symptoms (MSS) and fatigue among control room operators in a petrochemical plant in Iran. A total of 188 office workers (91 in the case group and 97 in the control group) participated at baseline as well as at 6- and 12-month follow-up. A questionnaire survey (including the Nordic Musculoskeletal Questionnaire and Multidimensional Fatigue Inventory) and direct observations of working postures by using the Rapid Upper Limb Assessment (RULA) method were used.

A review of the methodology and applications of anthropometry in ergonomics and product design.

Anthropometry is a key element of ergonomic studies for addressing the problem of fitting the tasks/products to user characteristics, but there is a gap between anthropometric data and their application for designing ergonomic products and environments. This research was conducted to review the literature on the methodology and applications of anthropometry for the ergonomic design of products and environments, and to identify where further research is needed to improve its application and evaluation protocols. One hundred and sixteen papers meeting the inclusion criteria were reviewed.
