일 농촌지역 주민에서 우울증상과 심박변이도의 관계

초록

Purpose: The purpose of this study is to investigate relationship between HRV (heart rate variability) and depressive symptoms in general population. This study was designed to examine the correlation of HRV and depressive symptom in general rural population. Methods: In 155 participants lived in the anonymous rural area of Gyeonggi-do, Korea, they participated in health promotion program with short term electrode HRV test and BDI (Beck’s depression inventory) self-report. Two participants were excluded due to fail to make out BDI and 58 participants were excluded because of some kinds of heart problems which were found after electrocardiogram and echocardiography exam of the health promotion program. We analyze HRV and BDI of remaining 95 subjects. Results: Our results showed that SDNN (standard deviation of the normal to normal interval), total power (TP), low frequency (LF), high frequency (HF) had negative correlation with BDI score, but only pNN50 (the proportion derived by dividing the number of interval differences of successive normal to normal intervals greater than 50 ms by the total number of normal to normal intervals) had positive correlation with BDI score. Also HF, LF and RMSSD (the square root of the mean squared differences of successive normal to normal intervals) are decreased by BDI severity grades increasing. Conclusion: In this findings of our study, some HRV variables seem to reflect subclinical depressive symptom severity in general rural population. (Korean J Str Res 2008;16:191∼197)
