[Professional stress and blood pressure reactivity to stress do not predict blood pressure at 5 years].
High job strain has been reported to be associated with higher blood pressure. Job strain could lead to hypertension if individual perception of stress or cardiovascular reactivity to stress are high. We report the results of the first five-year follow up study, which aimed to assess the respective influences of perception of professional strain and cardiovascular reactivity to a mental stress test on BP. A cohort of 292 healthy subjects (mean +/- SEM, 38 +/- 1 years) was followed for progression to hypertension outcome which was defined as an increase in SBP or DBP higher than 7 mmHg or a DBP higher than 95 mmHg during the follow-up. The high strain (HS) group representing 20.9% of the subjects was compared with the remaining subjects (NHS). Similarly the 20.9% subjects with the highest BP stress reactivity (HR) were compared with the remaining subjects (NHR). The Kaplan-Meier survival estimates revealed that neither high job strain, nor high stress reactivity, increased incidence of progression to hypertension. Age, alcohol, salt diet, BMI, and occupation did not interfere with our results. In conclusion, high stress cardiovascular reactivity and high job strain do not appear to be major risk markers for future high BP in healthy young adults. Stress could be associated with high BP at a short term and could explain high blood pressure in a long run only in stress-sensible subjects.
