국내 거주 외국인 가정폭력 피해 여성의 임상적 특징 및 심박변이도 = Clinical Characteristics and Heart Rate Variability of Foreign Domestic Violence Victims in Korea

국문 초록 (Abstract)

목 적 : 가정폭력에 노출된 여성은 우울증, 불안장애, 외상 후 스트레스 장애 등 다양한 정신 질환에 이환되기 쉽다. 심박변이도 검사는 자율신경계의 활성도와 균형을 평가하는 검사로 비침습적이고 재현성이 높아 정신 질환에 대한 연구에서도 폭넓게 활용되고 있다. 그러나 폭력 피해 여성에 대한 심박변이도 연구는 아직까지 부족한 실정이다. 본 연구는 국내 폭력 피해 여성의 인구사회학적 특징 및 심리학적 특징을 살펴보고, 한국인과 외국인 폭력 피해 여성의 임상적 특징과 심박변이도 검사 결과의 차이를 비교해보고자 하였다. 방 법 : 여성쉼터에 입소한 폭력피해 여성 중 2011년 12월 부터 2015년 12월까지 건강검진을 위해 서울의료원에 방문한 대상자 중 한국인 166명, 외국인 44명, 총 210명 대상으로 HAM-D, HAM-A, IES-R 등 임상 척도 평가와 심박변이도 검사를 실시하였다. 폭력 피해 여성 중 한국인과 외국인의 인구사회학적 특징, 심리적 특징, 심박변이도를 비교하기 위하여 카이제곱 검정 및독립 표본 t-검정 등을 시행하였다. 결 과 : 한국인과 외국인 폭력 피해 여성은 거주지, 유년시절폭력의 경험, 폭력의 지속기간에서 유의한 차이가 있었다. 한국인과 외국인 폭력 피해 여성 두 군 간의 HAM-A, HAM-D, IES-R 점수에는 유의한 차이가 없었다. 심박변이도의 세부지표에서는 ApEn 수치가 외국인 폭력 피해 여성군이 한국인보다 유의하게 높았고, RMSSD 수치는 외국인 폭력 피해 여성 군이 한국인보다 유의하게 낮은 결과를 보였다. 기타 HRV 세부지표에서는 한국인 폭력 피해 여성 군과 외국인 폭력피해 여성 군 두 군 간에 유의한 차이를 보이지 않았다. 결 론 : 국내 폭력 피해 여성은 우울, 불안, 외상 후 스트레스장애 증상을 가지고 있는 비율이 높았고 한국인과 외국인 간의 차이는 유의하지 않았다. 그러나 심박변이도 검사에서 외국인의 ApEn 값이 유의하게 높고 RMSSD 값이 유의하게 낮았다. 이는 한국인과 외국인의 인종 생리적 또는 이민 생활 등 환경적 영향의 차이일 수 있으며 향후 충분한 수의 외국인 대상자와 한국인을 비교, 추적조사를 통하여 요인간의 인과관계를 파악하는 연구가 필요할 것으로 보인다.

다국어 초록 (Multilingual Abstract)

Objectives: Domestic violence is related to many psychiatric diseases, such as depression, anxiety disorder, and PTSD. Heart rate variability (HRV) is an index of autonomic control of the heart and is related to cardiovascular and emotional disorders. Although there have been some studies on the effects of domestic violence on women's mental health, relatively little information is available on HRV in this population. The aim of this study is to investigate demographic data, psychological features, and HRV in female victims of domestic violence and difference between Korean and foreign female victims. Methods: A total of 210 female victims of domestic violence (166 Korean women and 44 foreign women) were recruited for this study. Psychological symptoms were measured using the Hamilton Rating Scale for Anxiety (HAM-A), Hamilton Rating Scale for Depression (HAM-D), and Impact of Event Scale-Revised (IES-R). HRV measures were assessed by time-domain and frequency-domain analyses. Results: The mean score of HAM-A was 13.81, that of HAM-D was 12.92, and that of IES-R was 33.61 ; there were no significant differences between Korean and foreign women in these measures. In HRV time domain analyses, approximate entropy (ApEn) was significantly increased in foreign women compared to the Korean women. The square root of the mean of the sum of the squares of differences between adjacent NN intervals (RMSSD) was significantly decreased in foreign women compared to Korean women. There were no significant differences in the other HRV variables between Korean and foreign women. Conclusion: Female victims of domestic violence in Korea are associated with depression, anxiety, and PTSD symptoms. The physiologic factors of a female victim's nationality could be related to higher ApEn and lower RMSSD in foreign female victims. These findings have important implications for future study to study the relationships among ethnic and environmental factors and HRV variables.
