Prevalence of dyslipidemia and its risk factors among three occupational populations in Nanjing city

Objective To investigate the prevalence of dyslipidemia and its risk factors among three occupational populations in Nanjing city,and to provide scientific evidences for health promotion among occupational populations.Methods Totally 2 141 employees were recruited from 2 large state-owned enterprises using stratified cluster random sampling method.The employees were divided into three groups( administration,technical service,and blue collar workers)according to their working position.A questionnaire survey and physical examination were used to collect related information of the participants and the data were analyzed with SPSS software.Results The overall prevalence rate of dyslipidemia was 16.0% among the participants,with the highest prevalence rate(22.3%) in the administration group,a moderate rate(15.8%)in blue collar workers,and the lowest(14.7%)in the technical service staff.The results of lgistic analyses showed that daily vegetable intake was a protective factor for the prevalence of dyslipidemia in the administration group.Smoking(odds ratio[OR]= 2.576,95% confidence interval[95% CI]= 1.325- 5.006),age,systolic blood pressure,and fasting plasma-glucose were risk factors of dyslipidemia in the technical service group;diabetes( OR = 2.508,95% CI = 1.169- 5.38),hypertension(OR = 2.445,95% CI = 1.455- 4.109),obesity( OR = 1.799,95% CI = 1.025-3.158),age,and alcohol drinking were the risk factors among the blue collar workers.Conclusion The prevalence of dyslipidemia and its risk factors were significantly different among occupational populations with different working positions and appropriate intervention measures should be taken for the occupational populations with various types of work.
