Title : The effects of personality and perceived stress on hypertension

Abstract:

Background. Considering the characteristics of Type A personality such as being impatient, competitive, short tempered, compulsive to time, easy to anger, etc., it could be assumed that people of Type A easily get stressed in their everyday lives, which could affect high blood pressure. Recent research analyzed whether Type A personality affects perceived stress and BMI levels leading to high blood pressure.

Methods. Type A score, Psychological perceived stress score (PWI-SF), BMI and SBP/BP data of total 2,748 samples (male: 1,255, female: 1493) from Ansan, Ansung cohort data based on the Korean Association Resource were used. After the measurement modeling (Confirmatory Factor Analysis), we performed the structural equation modeling to investigate direct, indirect and total effect of the variables.

Results. The direct influence of Type A on blood pressure was not significant in both genders. Type A positively affected the mediator perceived stress, and perceived stress negatively affected the mediator BMI which influences on blood pressure positively (on SBP: indirect effect, β=-0.082, p<0.05, on DBP: β=-0.065, p<0.05 in males, on SBP: indirect effect, β=-0.057, p<0.05, on DBP: β=-0.052, p<0.05 in females) in both genders. Only in the male group, Type A negatively affects BMI.

Conclusions. Type A can influence low blood pressure in an indirect way. Type A personality could affect perceived stress, and perceived stress has been shown to affect BMI negatively, which affects blood pressure. Contrary to the hypothesis that people who are vulnerable to perceiving stress have high blood pressure, it was found that when the perceived stress was high, the BMI level was lowered, resulting in lower blood pressure. Also, this is a different result from studies that show that stress induces binge eating and increases BMI. This study interpreted that the reason for this is that when Koreans get stressed, their appetite decreases and food intake decreases. This in turn lowers BMI, which has a positive effect on blood pressure finally.

What will audience learn from your presentation?

  • It is understandable that stress may have a bi-directional mechanism in the development and prevention of high blood pressure, which may increase or decrease the appetite.
  • When conducting a study on the effect of stress on disease, it is suggested that the study on the effect of obesity, depression, and eating disorders in particular should be designed in a two-way manner (positive and negative depending on people).
  • It was found that people with Type A tendencies feel stress easily in daily life, so we can discuss ways to relieve stress according to personal characteristics.
