Abstract

Abstract : In this study, we found that the insomnia, smoking, and job insecurity among live fire instructors were associated with decreased heart rate variability (HRV), suggesting that the HRV could be used to assess health conditions and to improve occupational environments among live fire instructors. Abstract : Objectives: This study aimed to identify the association between the healthrelated characteristics and the subscales of occupational stress of live fire instructors and heart rate variability (HRV). Methods: We conducted questionnaire survey on a general health checkup for 15 live fire instructors. Occupational stress and HRV parameters were measured to determine the association between health behavior, including smoking, drinking, exercise, and sleep-related disorders, and occupational stress of live fire instructors and HRV parameters using Spearman's rank correlation coefficient. Results: Smoking, insomnia, and job insecurity, a subscale of occupational stress measurement, showed negative Spearman rank correlations with HRV. Conclusions: Insomnia, smoking, and job insecurity (due to occupational stress) among live fire instructors were associated with decreased HRV.
