Abstract
Objective: To explore the job stress effect on risk of stroke and arterial hypertension (AH) in female population of 25-64y in Russia over 16 years of follow-up. Methods: Under the third screening of the WHO "MONICA-psychosocial" program random representative sample of women aged 25-64 years (n=870) were surveyed in Novosibirsk. Levels of job stress were estimated by questionnaire based on Karasek's job demands-control model. From 1995 to 2010 women were followed for the incidence of AH, stroke. Cox regression model was used for risk assessment (HR). Results: The prevalence of high job stress level in women aged 25-64 years was 31.6%. HR of stroke over 16 years of follow-up was 1.96-fold higher (95.0%CI:1.01-3.79, p<0.05) in women with job stress, HR of AH was 1.39-fold higher (95.0%CI:1.08-1.78, p=0.01) compared to those without stress. There were tendencies of increasing stroke and AH rates in married women experienced stress at work. Stroke developed in women with lower educational level and AH significantly higher developed in women with higher educational level (p for all <0.05) having job stress. AH and stroke rates was found higher for physical workers with job stress (χ2=5.47 df=1 p<0.05) and AH rates were tend to be higher in managers experienced stress at work. Conclusions: There is high prevalence of stress at work in female population aged 25-64y in Russia. Women with job stress have significantly higher risk of stroke and AH over 16-th years of follow-up, especially in married ones and in physical workers with job stress.
