# Psychosocial factors associated with fatigue in mining work

## TL;DR

This study explores how psychosocial factors like work demands and social support affect fatigue among mining workers, particularly heavy vehicle drivers.

## Contribution

The study identifies specific psychosocial factors linked to fatigue in mining work, emphasizing the role of work organization and social support.

## Key findings

- Fatigue was associated with marital status, education, lifestyle habits, and psychosocial factors at work.
- High work demands and low social support were most related to fatigue dimensions.
- Passive work with low social support was common among the most fatigued workers.

## Abstract

Fatigue is related to lifestyle habits and working conditions. In the
corporate environment, the organization and type of work, as well as social
support, can cause or aggravate fatigue and its dimensions (sleepiness and
indisposition to work, difficulty concentrating and paying attention, and
physical discomfort).

To assess the prevalence of fatigue and its association with biosocial
characteristics, job demands, and the risk of fatigue in heavy vehicle
drivers in the mining sector.

A cross-sectional study with 111 workers used the biosocial and
organizational questionnaire, the Job Stress Scale for psychosocial
assessment, and the Yoshitake Fatigue Assessment Questionnaire as
instruments.

Fatigue was associated with marital status, education, lifestyle habits, and
psychosocial factors at work. Most fatigued workers were exposed to passive
work with low social support.

Driving heavy vehicles did not increase the risk of fatigue; however, high
work demands and low social support were the psychosocial factors most
related to the dimensions of fatigue.
