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). <br><br>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. <br><br>RESULTS: Smoking, insomnia, and job insecurity, a subscale of occupational stress measurement, showed negative Spearman rank correlations with HRV. <br><br>CONCLUSIONS: Insomnia, smoking, and job insecurity (due to occupational stress) among live fire instructors were associated with decreased HRV.<p /> <p>Language: en</p>",
