Influence of environmental variables on students' cognitive performance in indoor higher education environments.

Background: Educational environments can have environmental conditions that are incompatible with the needs of students, compromising their well-being and affecting their performance.

Objective: To identify the environmental variables that influence the performance of university students and measure this influence through an experiment in indoor environments.

Methods: The study applied an experimental methodology for three consecutive days in seven educational environments located in different regions of Brazil, measuring the environ-mental conditions, the students' perception of the environment, and their cognitive performance.

Quantitative analysis of the influence of air temperature variability on thermal perception of Brazilian university students.

Background: The scientific literature has already identified the influence of thermal conditions on health and performance of students. However, users' opinions are often overwhelmed by normative evaluations, not receiving the necessary attention.

Objective: To quantitatively compare the influence of air temperature variability on the thermal perception of students from six air-conditioned teaching environments located in four regions of Brazil.

Sickness absence from work in the footwear industry: A longitudinal study.

Effects of a worksite physical activities program among men and women: An interventional study in a footwear industry.

The study aims to assess the association between various levels of engagement in a worksite physical activities program and variables related to musculoskeletal symptoms, psychophysiological well-being, difficulty to perform tasks, willingness to work, and interpersonal relationships, among men and women in a footwear industry. This program involved 1113 workers. Data were analysed using an ordinal logistic regression model.

Risk factors for work-related musculoskeletal disorders among workers in the footwear industry: a cross-sectional study.

The aim of the study was to investigate the influence of biomechanical, psychosocial, environmental and individual factors on local and multisite work-related musculoskeletal disorder (WMSD) symptoms among workers at a footwear manufacturing company. The sample comprised 267 workers. The results showed that: (a) age, sedentary lifestyle, inappropriate posture and perceived effort were associated with symptoms in the shoulders, and the combination of these factors increased the odds four-fold; (b) inappropriate posture, perceived effort and bullying were related to symptoms in the wrists, and the combination of these factors increased the odds seven-fold; (c) inappropriate posture, perceived effort, length of work at the company and low social support were associated with multisite symptoms, and their combination increased the odds up to 30-fold.
