Abstract
Objectives: The aim of this study was to investigate factors associated with heart rate variability in firefighters
working in a metropolitan city in South Korea.
Methods: Self-administered questionnaires including Korean Occupational Stress Scale (KOSS) as well as surveys
collecting socio-demographic characteristics and work-related factors were given to 962 firefighters. After exclusion
for missing data, 645 firefighters were included, and analysis of covaiance adjusted for the general risk factors and
job characteristics were used to assess the relationship between heart rate variability and associated factors.
Results: SDNN and RMSSD and were decreased in the area of occupational climate of the group with high job
stress (p = 0.027, p = 0.036). HF(ln) was decreased in the area of organizational system and occupational climate of
the group with high stress that statistically significant level (p = 0.034, p = 0.043).
Conclusions: Occupational climate and organizational system are associated with reduction of heart rate variability.
Preventive medical care plans for cardiovascular disease of firefighters through the analysis and evaluation of job
stress factors are needed.
