| Summary: | Objectives
The study aimed to examine the relationship between occupational factors and sleep disorders among employees in petrochemical enterprises.
Material and Methods
All participants from the employees of Hainan Petroleum Refining and Chemical Enterprises were recruited by
the cluster sampling in June 1, 2022. The questionnaire used in this research was primarily composed of 3 sections: demographic characteristics,
Pittsburgh Sleep Quality Index (PSQI) questionnaire and occupation-related factors affecting sleep disorders. A 1:1 propensity score matching (PSM)
method was used to balance the demographic characteristics of the 2 groups. Multivariate logistic regression was employed to analyze the independent
factors influencing sleep disorders.
Results
A total of 952 valid questionnaires were collected. The frequency of sleep disorders among the
952 participants was 41.9% (N = 399). After PSM, 356 pairs were successfully matched. There was no statistical difference in socio-demographic
characteristics between sleep disorder groups (p > 0.05). The logistic regression analysis showed that employees with weekly working time >40 h
exhibited a higher likelihood of sleep disorders (OR: 1.74, 95% CI: 1.09–2.82) than those working ≤40 h. Individuals exposed to high-temperature
working environments were more likely to experience sleep disorders (OR: 1.77, 95% CI: 1.12–2.81), while the sleep disorder risk in those with occupational
stress was 2.67-fold (OR: 2.67, 95% CI: 1.89–3.80). Employees in storage and transportation (OR: 3.34, 95% CI: 1.81–6.40) and other positions
(OR: 1.68, 95% CI: 1.03–2.75) displayed a higher risk of sleep disorders than operational workers.
Conclusions
The frequency of sleep disorders
among employees in petrochemical enterprises is high. Weekly working hours, type of work position, high-temperature exposure, and high
occupational stress are associated with increased risk of sleep disorders among petrochemical workers. Health policymakers should fully consider
these factors in improving the sleep quality of petrochemical workers. Int J Occup Med Environ Health. 2024;37(6):591–601 |
