As a result, it also makes everyone more jobs, more stress and even more fatigue resulting in sudden death. Thus, we conducted a cross-sectional study to investigate the associations of work stress, fatigue and indicators of cardiovascular diseases. Participants recruited from one Air Force base agreed to complete two-part questionnaire that one is for defining the characteristics of work and the other is for scaling the strength of fatigue. Finally, they also needed to be measured indicators of cardiovascular diseases like BMI, waist circumference, blood pressure, fasting glucose and different kinds of cholesterol.
Finally, 297 questionnaires were analyzed excluding 55 questionnaires which 30 were refused to fill and 25 were not provided enough information by participants. Response rate was highly 86.4%. In demographic analysis, there were 251(84.5%) male and 46(15.5%) female. Participants were 26.9% above and sergeant in rank and 87.6% were staff officers. In life habit, no betel-nut chewing, alcohol drinking, and no-smoking were separately 87.6%, 68.5% and 61.4%. It is up to 57.7% participants regularly doing physical activity once or twice per week and lasting at least 30 minutes.
According to the Karasek’s demand-control model of job stress, there were 68(22.9%) low-demand-and-low-control (passive jobs) participants. Low-demand-and-high-control (lowstrain jobs), high-demand-and-low-control (highstrain jobs) and high-demand-and-high-control (active job) ones were distinguishingly 82(27.6%), 92(31.0%), and 55(18.5%). There were 136(45.8%) whose scores in the strength of fatigue were above 76. 161(54.2%) participants self-perceived that fatigue was mainly originated from psychological factors. However, numbers of elevated total cholesterol (>200mg/dl), elevated LDL-C (>130mg/dl), elevated triglyceride (>150mg/dl), elevated fasting glucose (>100mg/dl), low HDL-C (<35mg/dl) were 116(39.1%), 94(31.8%), 53(17.8%), 28(9.4%), and 20(6.7%). In addition, there were 205(69.0%) and 61(20.5%) in elevated blood pressure (>120/80mmHg) and BMI(≧27kg/m2). In elevated waist circumference, it had 45(15.2%) restricted in male participants (>90cm).
Our results showed that officers had better outcomes than others in assessment of work stress. Overall prevalence of fatigue was 45.8% in our study. In the univariate analysis, prevalence of fatigue was significantly associated with factors including LDL-C, physical activity, job demand, job control, social support in workplace and work insecurity. Finally, factors of LDL-C, physical activity, job control, and social support in workplace were positively associated with prevalence of fatigue in the multivariate analysis.
