Summary
Background:
Unemployment has consistently been associated with increased risk of cardiovascular disease and premature mortality, especially among men, but the precise mechanisms are less clear. The aim of the study is to examine the association between cardiac autonomic activity and unemployment in men.
Methods and results:
The study sample consisted of 15 job-seeking and 15 employed men aged 30–49 years, matched on number of potentially confounding variables, including age, type of job, frequency of physical activity, smoking habits, self-reported alcohol intake, and body mass index. Heart rate variability was measured during a modified orthostatic test. Repeated measures ANOVA demonstrated significantly lower (p = 0.040) overall heart rate variability in job-seeking men compared to controls. Effect was independent of psychosocial and/or behavioral factors that influence HRV.
Conclusion:
Findings suggest that seeking a job is a potential stressor that may reduce overall heart rate variability and lead to disturbance of cardiac autonomic activity. This could be one of the processes explaining the increased cardiovascular disease risk in job-seeking men.
Keywords:
