Psychosocial Factors and Personality Traits and the Prevalence of Arterial Hypertension Among 35- and 55-Year-Old Men and Women in Sweden and Estonia: a SWESTONIA Longitudinal Study

INTRODUCTION

Psychosocial factors influence the risk of developing hypertension. Personality traits have a modulating effect against the harmful influences of psychosocial factors.

AIM

Through a longitudinal clinical study consisting of men and women aged 35 and 55 at the baseline in Estonia and Sweden, to assess the influence of psychosocial factors and personality traits resulting in arterial hypertension.

METHODS

Data analysis based on the cross-sectional study with 2 assessments over 13 years of a sample comprising 158 individuals from Estonia and 213 individuals from Sweden. The Pearlin Mastery Scale, Rosenberg Self-esteem Scale, Depression Model and Gothenburg Quality of Life Instrument were used.

RESULTS

Throughout the follow-up period, a higher depressive mood and lower self-assessed quality of life score prevailed among the 35-year-old and 55-year-old Estonians compared with the Swedish study participants (p < 0.001). Among the 55-year-old Estonian study participants with diagnosed hypertension, but not among the Swedish, negative stressful life events had a significantly stronger effect (p < 0.001) on the risk of developing hypertension. In addition, lower mastery (p < 0.05) dominated among study participants diagnosed with hypertension.

CONCLUSIONS

The combined effects of psychosocial factors and personality traits are important variables in predicting the risk of developing arterial hypertension. The study results are relevant to clinical practice and provide suggestions for employing successful preventive measures.

The Fear-Avoidance Model of Musculoskeletal Pain: Current State of Scientific Evidence

Research studies focusing on the fear-avoidance model have expanded considerably since the review by Vlaeyen and Linton (Vlaeyen J. W. S. & Linton, S. J. (2000). Fear-avoidance and its consequences in chronic musculoskeletal pain: a state of the art. Pain, 85(3), 317--332). The fear-avoidance model is a cognitive-behavioral account that explains why a minority of acute low back pain sufferers develop a chronic pain problem. This paper reviews the current state of scientific evidence for the individual components of the model: pain severity, pain catastrophizing, attention to pain, escape/avoidance behavior, disability, disuse, and vulnerabilities. Furthermore, support for the contribution of pain-related fear in the inception of low back pain, the development of chronic low back pain from an acute episode, and the maintenance of enduring pain, will be highlighted. Finally, available evidence on recent clinical applications is provided, and unresolved issues that need further exploration are discussed.
