We examined the relationship between unemployment and heart rate variability (HRV) in a region of high unemployment in the Czech Republic. The study involved 21 involuntarily unemployed and 21 employed men and women aged 30-49 years, matched on number of potentially confounding factors, including age, gender, type of job, health related behavior and body mass index. HRV was assessed in response to a modified orthostatic test. Compared with the employed group, unemployed participants had decreased high frequency HRV (p=0.018), lower root mean square of successive differences (p=0.050), and lower total spectral variability (p=0.022). These findings suggest that unemployment is a potential chronic stressor that may lead to suppression of vagal activity. This may be one mechanism linking unemployment with cardiovascular disease risk.
我们研究了在捷克共和国失业率较高地区失业与心率变异性（HRV）之间的关系。该研究涉及 21 名非自愿失业的男女和 21 名受雇的 30-49 岁男女，根据潜在混杂因素（包括年龄、性别、工作类型、健康相关行为和体重指数）进行匹配。HRV 是通过改良的直立倾斜试验进行评估的。与受雇组相比，失业组参与者的高频 HRV 降低（p=0.018），均方根差值降低（p=0.050），总频谱变异性降低（p=0.022）。这些发现表明，失业可能是一种潜在的慢性应激源，可能导致迷走神经活动受到抑制。这可能是将失业与心血管疾病风险联系起来的一种机制。
