Abstract:
Background:Mining is a major source of income, economic benefits,
and job creation; however, it remains one of the most hazardous occupations
in terms of health. Physically demanding, labor-intensive, hot,
humid, noisy, and dusty work environments have a negative impact on
the physical and psychological health of mine workers. Several factors,
including age, gender, years of service, workload, stress, and fatigue,
can affect sleep quality. Lack of sleep can lead to poor concentration,
reduced alertness, impaired decision-making, and an increased risk of
workplace injuries. While many studies have explored sleep quality and
its risk factors in the general population, few have focused specifically
on miners. This gap is the primary motivation for conducting the present
study.
Aim:To examine the risk factors affecting the sleep quality of dayshift
workers at Baganuur Joint Stock Company.
Materials and Methods:This cross-sectional study included 129 day-shift workers from
Baganuur Joint Stock Company and was conducted between October
and November 2023. Sleep quality was assessed using the 19-item
Pittsburgh Sleep Quality Index (PSQI) questionnaire. Data were analyzed
using SPSS version 26.0, with statistical significance set at p <
0.05.
Results:Among the study participants, 86% (n = 111) were male.
A total of 58.9% had been employed for less than 10 years, and 86%
were always on call during non-working hours. Overall, 51.2% of the
participants had poor sleep quality. Female gender (55.0%, p = 0.032)
and being always on call during non-working hours (93.9%, p = 0.008)
were significantly associated with poor sleep quality. Logistic regression
analysis revealed that being female increased the risk of poor sleep
quality (OR = 0.315, 95% CI = 0.105–0.944, p = 0.039).
Conclusions:1. The majority of participants (51.2%) reported poor sleep quality, 2.
Gender and being on call during non-working hours were significantly
associated with reduced sleep quality among day-shift miners.
