Objective To investigate the prevalence of dyslipidemia among subway staff in Wuhan, China, and explore the direct and indirect effects of factors affecting dyslipidemia by using structural equation modeling, so as to provide evidence for health risk management the risk of health for staff.
Methods Based on the subway employee health survey project conducted in collaboration between Wuhan Metro Group and Wuhan Center for Disease Control and Prevention, a total of 6 385 subway staff who completed the questionnaire survey and physical examination were selected as the research objects from May 2018 to October 2019. Data were analyzed by SAS 9.4 software, and the structural equation model of influencing factors of dyslipidemia was constructed by Amos 21.0.
Results The prevalence rate of dyslipidemia among Wuhan subway staff was 15.00%, mainly hypertriglyceridemia (66.70%) and hypercholesterolemia (13.26%). The result of structural equation model showed that age had direct and indirect effects on the incidence of dyslipidemia, with a total path coefficient of 0.17. The direct path coefficient of physiological conditions for the prevalence of dyslipidemia was 0.52, in which hypertension contributed most with a path coefficient of 0.24. Current smoking showed a direct effect on the prevalence of dyslipidemia, and the path coefficient was 0.07, indicating that risk of dyslipidemia in current smoking was 0.07 higher than that in non-smoking (all P < 0.01).
Conclusion The prevalence of dyslipidemia among Wuhan subway staff was at a low level, but it was still necessary to strengthen health education to improve staff's awareness of the harm of dyslipidemia, and pay more attention to monitoring of blood lipids, blood pressure, and other indicators so as to reduce the risk of dyslipidemia.
