Does work-related psychological stress increase arterial stiffness measured by baPWV in young Japanese male workers?
In young Japanese male workers, high job strain was unexpectedly associated with lower arterial stiffness, challenging the traditional job-strain hypothesis in this specific cultural and occupational context.

OBJECTIVES: This study examined the relationship between work-related psychological stress and arterial stiffness in young Japanese workers. METHODS: A cross-sectional study was conducted on 396 Japanese male workers, aged 24 to 39 years, employed in a Japanese information service company. Work-related psychological stress was measured by the Job Content Questionnaire based on the job demand-control model. The job-strain index was defined as the ratio of job demand to job-control scores. The outcome of the study was the degree of arteriosclerosis as assessed by brachial pulse-wave velocity (baPWV). The cardiovascular risk factors analyzed were age, heart rate, blood pressure, body mass index, serum lipid, blood sugar levels, catecholamine levels, ethanol consumption, smoking, and overtime. In addition, psychological responses were assessed by tension-anxiety and anger-hostility scales in the Profile of Mood States (POMS). RESULTS: The baPWV was positively (P<0.05) associated with physiological variables including age, heart rate, body mass index, and serum levels of total cholesterol, fasting glucose, and noradrenaline, but negatively (P<0.01) associated with the job-strain index. Significant associations were not found on the POMS tension-anxiety and anger-hostility scale scores. The negative correlation between baPWV and the job-strain index was consistent even after control for the effects of significant physiological variables. CONCLUSIONS: The association between job stress and baPWV was found to be inconsistent with the results of previous western studies, and it may require further investigation while taking into account occupation, cardiovascular risk factors, and Japanese culture.
Nomura et al. (Sat,) conducted a cross-sectional in Arterial stiffness and work-related psychological stress (n=396). Work-related psychological stress (Job strain) vs. Low job strain was evaluated on Brachial-ankle pulse-wave velocity (baPWV) (Regression coefficient -1.382, p=<0.01). Work-related psychological stress (job strain) was negatively associated with arterial stiffness measured by brachial-ankle pulse-wave velocity in young Japanese male workers (regression coefficient -1.382, p<0.01).
