<![CDATA[Coal mining vehicle operators have negative consequences with health effects such as fatigue. The aim of the study was to analyze the risk factors related to subjective fatigue among coal mining operators. Specifically, it seeks to examine the relationship between work shift, working period, sleep quantity, sleep quality, and personal characteristics, such as age, neck circumference, and body mass index. Data were collected from a coal mining site in South Kalimantan, Indonesia in 2022 with primary questionnaires. A total of 440 workers who worked in the mining and hauling area for at least one year were recruited in this study. This was a cross-sectional study. Quantitative data were obtained to describe the level of subjective fatigue and to analyze the risk factors associated with the work fatigue in coal mining vehicle operators. The fatigue was associated with obesity (OR:1.777, 95% CI:1.0067-2.960), overweight (OR:1.783, 95% CI:1.046-3.040), neck circumference (OR:1.513, 95% CI:1.0983-2.329), sleep quality (OR:4.597, 95% CI:2.762-7.650), and working period (OR:0.545, 95% CI:10.360-0.825) (p<0.05 for all). However, fatigue did not significantly affect from sleep quantity and work shift. Ensuring individual health is essential for preserving the opportunity to sleep and allowing the body to recover from fatigue.]]>
