Cardiovascular Risks in High-Stress Occupations

Abstract

Background: Cardiovascular disease is one of the leading causes of death worldwide. A growing body of research link long-term occupational stress to increased cardiovascular risk, especially in high-stress jobs such as transportation, aviation, logistics, and public administration. These roles are often characterized by long hours, low autonomy, high demands, and inadequate support – factors that contribute to both psychological strain and physiological health deterioration.

Hypothesis: Individuals working in high-stress occupations are at a significantly increased risk of developing cardiovascular disease compared to those in lower-stress roles. Factors such as job control, gender, and organizational support moderate the strength of this relationship.

Aim and Objectives: This thesis aimed to explore the connection between occupational stress and cardiovascular health in high-stress professions through a systematic literature review. The objectives were to examine how stress influences cardiovascular disease, identify the most affected occupations, understand underlying biological and psychosocial mechanisms, and evaluate effective prevention strategies.

Methods: A systematic review of 19 peer-reviewed studies was conducted using thematic analysis. Studies were selected based on relevance, methodological quality, and alignment with the research questions. Key data were extracted on occupational categories, stress levels, health outcomes, and intervention approaches.

Result: The findings confirmed a strong association between occupational stress and elevated cardiovascular risk. Workers in high-strain jobs exhibited increased rates of hypertension, inflammation, hormonal imbalance, and reduced cardiovascular fitness. The risk was higher in jobs with low control, high effort, and poor reward systems. Gender, social support, and job design acted as moderating factors. Preventive measures ranged from individual stress management to organizational reforms and national policy intervention.

Conclusion: Occupational stress is a significant and modifiable contributor to cardiovascular disease. Addressing this issue requires a multi-level approach, combining individual support with structural and policy changes. Future research should prioritize long-term studies and include underrepresented professions and vulnerable populations.
