Abstract

Objectives : The purpose of this study is to identify the effect of office workers' stress level and stress vulnerability on heart rate variability (HRV), confirm the significance of objective stress indicators obtained through subjective stress and heart rate variability devices, and examine their effectiveness as an integrated stress measurement tool in community mental health projects. Methods : From June to July in 2020, 929 workers participated in the stress management and mental health promotion project carried out by K hospital, and their recorded database was used for study analysis with their agreements. Multiple linear regression analysis was performed to find out the effects of general stress level, and stress vulnerability on heart rate variability. Results : All general characteristics were found to have a significant effect on SDNN (ln), RMSSD (ln), LF (ln), and HF (ln), but work experience did not significantly affect RMSSD (ln). Stress level and stress vulnerability did not significantly affect heart rate variability, but stress perception, a sub-factor of stress level, was found to have a significant effect on RMSSD (ln) (β=0.118, p=0.023). Conclusions : In this study, stress perception, a sub-factor of stress level, was found to be a factor affecting RMSSD (ln). This indicates an association with the activity of parasympathetic nerves in stressful situations, and more follow-up studies are needed to use it as a direct indicator of chronic stress and integrated stress in the community mental health field.

연구목적 이 연구는 직장인의 스트레스 수준과 스트레스 취약성이 심박변이도(Heart rate Variability, HRV)에 미치는 영향을 파악하여 주관적인 스트레스와 심박변이도 기기를 통해 얻어진 객관적 스트레스 지표의 유의성을 확인하고 지역사회 정신건강사업에서 통합적 스트레스 측정도구로서의 효과성을 검토하고자 하였다. 방 법 2020년 6월부터 동년 7월까지 K병원에서 수행한 직장인의 스트레스 관리 및 정신건강증진 사업에 참여하고 연구에 동의한 대상자 929명의 기록 데이터베이스를 분석하였다. 일반적 특성과 스트레스 수준 및 스트레스 취약성이 심박변이도에 미치는 영향을 알아보기 위하여 다중선형회귀분석을 실시하였다. 결 과 일반적 특성 모두 SDNN (ln), RMSSD (ln), LF (ln), HF (ln)에 모두 유의한 영향을 주는 요소로 나타났지만 근무경력은 RMSSD (ln)에 유의한 영향을 미치지 않는 것으로 확인되었다. 스트레스 수준 및 스트레스 취약성은 심박변이도에 유의한 영향을 미치지 않았지만 스트레스 수준의 하위 요인인 스트레스 지각이 RMSSD (ln)에 유의한 영향을 주는 요인으로 확인되었다(β=0.118, p=0.023). 결 론 본 연구에서 스트레스 수준의 하위요인인 스트레스 지각이 RMSSD (ln)에 영향을 미치는 요인으로 나타났다. 이는 스트레스 상황에서 나타나는 부교감신경의 활성과의 관련성을 나타내는 것으로 지역사회 정신건강 현장에서 만성 스트레스 및 통합적 스트레스의 직접적인 지표로 평가하기에는 더 많은 후속 연구가 필요할 것으로 보인다
