Low Estimated Glomerular Filtration Rate Is Prevalent among North Korean Refugees in South Korea / 가정의학회지

BACKGROUND: The number of North Korean refugees entering South Korea is rising. Few studies have investigated the risk of non-communicable disease in North Korean refugees. Moreover, kidney insufficiency, a risk factor for cardiovascular disease, has not been studied in this population. We compared the prevalence of non-communicable disease and kidney function in North Korean refugees and South Koreans. METHODS: Our study was conducted using a case-control design. We enrolled 118 North Korean refugees from the Hana Center and selected 472 randomly sampled South Korean individuals as controls, who were age- and sex-matched with the North Korean refugees in a ratio of 1:4, from the 2014 Korea National Health and Nutrition Examination Survey database. RESULTS: The prevalence of non-communicable disease did not differ significantly between the groups; however, a low estimated glomerular filtration rate (eGFR; < 90 mL/min per 1.73 m2) was more prevalent in the North Korean refugees than in the South Korean population (52.1% vs. 29.9%, P < 0.001). After adjusting for covariates and weight gain after escape, the prevalence of a low eGFR was associated with the length of residence in South Korea (odds ratio, 2.84; 95% confidence interval, 1.02–7.89). CONCLUSION: The prevalence of non-communicable disease did not differ between North Korean refugees and the South Korean population, while a low eGFR was more prevalent in North Korean refugees than in South Koreans. Moreover, after adjusting for other covariates, the prevalence of a low eGFR in North Korean refugees was associated with the length of residence in South Korea.

Determinants of North Korean Refugees' Trust in South Korea Health Service / 보건행정학회지

BACKGROUND: The purpose of this study was to investigate the determinants of North Korean refugees' trust in South Korea health service. METHODS: This study surveyed 168 North Korean refugees aged 19 and over living in Seoul, Gyeonggi, Incheon, and Gangwon. The collected data were analyzed by frequency analysis, t-test, analysis of variance, and hierarchical regression analysis to analyze the effect on the trust of refugees. RESULTS: The difference analysis showed statistically significant difference according to duration of residence and employment status. The determinants of North Korean refugees' trust in South Korea health services were duration of residence, basic communication skills, health communication skills, and experience of health service. CONCLUSION: In order to increase the trust of North Korean defectors in South Korea medical services, it is necessary to resolve communication problems and improve the satisfaction of health services. For this, the interpreter service should be activated. And specific education should be given to the North Korean refugees about the health care system and the utilization methods of health service in Korea.

Gender Differences in Suicidal Ideation and Related Factors among North Korean Refugees in South Korea

OBJECTIVE: According to previous social survey, a high number of North Korean refugees (NKRs) in South Korea had suicidal ideation. The purpose of this study is to examine the related factors for suicidal ideation among NKRs by gender in South Korea. METHODS: We examined the sample of NKRs, 701 subjects (men=160, women=-541) residing in South Korea, the participants were enrolled from October 2008 to May 2014. The related factors with suicidal ideation in NKRs were analyzed via a logistic regression analysis. RESULTS: Refugee women were more likely to have suicidal ideation than men were. Although thoughts of suicide do not necessarily mean that they will follow through, however, there is an association that the higher rate of suicide also results in a higher rate of attempted suicide. In both genders, they tended to think more frequently about suicide who had stayed in South Korea for more than 5 years. In addition, higher frequencies of suicidal ideation also associated with higher level of perceived stress in both genders. CONCLUSION: The gender difference should be addressed when designing suicide prevention interventions among the North Korean population in South Korea.

Post-Traumatic Stress Disorder, Depression and Anxiety among North Korean Refugees: A Meta-Analysis

OBJECTIVE: Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. METHODS: Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. RESULTS: A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), p<0.001, z=8.33, and anxiety, r=0.51, 95% CI (0.36, 0.63), p<0.001, z=6.07. The relationships between post-traumatic stress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. CONCLUSION: Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

Effects of Psychiatric Symptoms on Attention in North Korean Refugees

OBJECTIVE: We investigated the performance of North Korean refugees on attention tasks, and the relationship between that performance and psychiatric symptoms. METHODS: Sustained and divided attention was assessed using the computerized Comprehensive Attention Test in North Korean refugees and in South Koreans. All participants also completed the Beck Depression Inventory, the Beck Anxiety Inventory, the Impact of Event Scale-Revised and the Dissociative Experiences Scale-II (DES-II). RESULTS: The North Korean refugees showed slower reaction times (RTs) on the visual sustained attention task compared to the South Koreans after controlling for age and sex. North Korean refugees had a greater number of omission errors (OEs) on the divided attention task and a higher standard deviation (SD) of RT. Total DES-II scores of the North Korean refugees were associated with the number of OEs and the SD of RT on the sustained attention task, and with the number of OEs on the divided attention task. CONCLUSION: North Korean refugees showed poorer performance on computerized attention tasks. In addition, attention deficit among North Korean refugees was associated with their dissociative experiences. Our results suggest that refugees may have attention deficits, which may be related to their psychiatric symptoms, particularly dissociation.

Characteristics of Body Composition and Muscle Strength of North Korean Refugees during South Korean Stay

BACKGROUND: The aim of this study was to investigate the changes of body composition and muscle strength of North Korean refugees (NKRs) according to their duration of stay in South Korea. METHODS: NKRs who volunteered and were living in South Korea, aged 20 to 75 years were recruited. Body compositions were analyzed by bioelectrical impedance analysis. Muscle strength was measured with the hand grip test. Demographic and migration information was obtained with a questionnaire. RESULTS: A total of 158 volunteers were recruited at a mean age of 48.3+/-11.4 years. The mean time from when they escaped from North Korea and arrived in South Korea was 5.8+/-4.3 years. Height, weight, and body surface area were significantly smaller in all NKRs compared to South Korean controls, except for women aged over 50 years. In females of younger ages (<50 years), NKRs with more than a 4-year stay in South Korea had a higher weight and fat mass than that of those who had a shorter stay (less than 4 years) in South Korea. All NKRs had a weaker grip strength than that of the age-matched controls from South Korea. CONCLUSION: The NKRs showed relatively smaller physiques and weaker muscle strength than that of the South Korean controls. In younger female NKRs, shorter South Korean stay group showed small body weight and fat mass than that of longer South Korean stay group. Specific health support programs might be needed.

Causes of Burnout among South Korean Counselors Working with North Korean Refugees: A Qualitative Content Analysis / 정신간호학회지

PURPOSE: This study was done to identify the causes of burnout among South Korean counselors for North Korean refugees. METHODS: Data were collected using open-ended questions in a survey from 85 South Korean counselors for North Korean refugees, and a content analysis of the textual data from the questions was conducted. RESULTS: A total of 192 statements were selected from the data and those were categorized into 3 domains, 8 categories, and 24 sub-categories. Institutional, client, and social recognition domains emerged. Findings indicate that the causes of burnout were derived from the following categories: 1) the categories for the Institutional domain were physical environment, work conflict, and work overload, 2) for the client domain, lack of cooperation, selfish attitude, and limits to interventions, and 3) for the social recognition domain, lack of rewards and identity confusion. CONCLUSION: The results indicate that community mental health professionals need to understand these causes of burnout among the counselors working with North Korean refugees. It is also necessary to do further research to develop strategies to prevent burnout and potential mental health problems for these counselors.

Thyroid Dysfunction of North Korean Women Living in South Korea, Focusing on Subclinical Hypothyroidism

BACKGROUND: Thyroid function depends on ethnic and environmental factors. North Korean refugees have the same genetic background as South Koreans, but they have been exposed to different environments. This study examines the prevalence and pattern of thyroid disorders in North Korean women living in South Korea, focusing on subclinical hypothyroidism (SCH). METHODS: The intended sample was a total of 327 North Korean women residing in Seoul. Health questionnaires and medical examinations, including serum thyrotropin (thyroid stimulating hormone, TSH), free thyroxine, and thyroid autoantibodies, were conducted. RESULTS: The prevalence of SCH was 9.4%. In logistic regression analysis, smoking, menopause, length of stay in South Korea, body mass index, history of thyroid disease, and metabolic syndrome were not associated with the risk of SCH. Whereas, the positivity of autoantibodies were associated with a high risk for SCH (odds ratio [OR], 4.840; 95% confidence interval [CI], 1.80-13.017; P = 0.002), and age was associated with a low risk for SCH (OR, 0.94; 95% CI, 0.888-0.994; P = 0.031). The serum TSH levels also decreased with increasing age, and in particular, there was significant difference between 30-39 years, and over 60 years (2.33 +/- 1.51 microIU/mL vs. 1.54 +/- 0.73 microIU/mL, P = 0.028). CONCLUSION: In North Korean women, the positivity of autoantibodies was associated with a high risk for SCH. But interestingly, a younger age was associated with a high risk for SCH. Considering that they suffered from severe famine at the period of growth, and this led to malnutrition, their thyroid dysfunction might be associated with the peculiar environment that they experienced.

A Study of Psychiatric Problems of North Korean Refugees Who Visited a Psychiatric Clinic / 수면정신생리

PURPOSE: According to the statistics announced by the Ministry of Unification, the number of North Korean refugees living in South Korea has increased by 200 on average monthly in 2010. The number of refugees increased only by 300 annually until 2000. The total number of refugees as of February 2012 was 20,956. This study aims to investigate the psychobiology of the North Korean refugees who consulted psychiatric clinics among those living daily life in South Korea. METHODS: The subjects of this study were 85 North Korean refugees that consulted psychiatric clinics from January 1, 2005 to July 2011. This study obtained demographic and psychiatric information in a retrospective approach. RESULTS: Among the 85 North Korean refugees, 75 (88.2%) were females and their average age was 48 years of age. A total of 16 (18.8%) were admitted to a clinic and among the inpatients, 4 were admitted twice and two were admitted three times. As for the claimed symptoms of outpatients, insomnia was shown in 47 (55.3%) patients, headaches in 37 (43.5%), anxiety in 20 (23.5%), depression in 19 (22.4%), etc. The major symptoms represented by inpatients were insomnia in 14 (87.5%) patients, depression in 12 (75%), and headaches in 8 (50%), etc. CONCLUSION: The most frequent psychiatric symptoms of North Korean refugees living in South Korea were insomnia and headaches. It suggests that when performing psychiatric diagnosis and treatment of North Korean refugees, we have to take into consideration the fact that they claimed the physical symptoms more than the emotional ones. Also, from the aspect that most symptoms of North Korean refugees were insomnia, more profound research on sleep is required in the future.

Development of Group Therapy Program for North Korean Refugees with Posttraumatic Stress Disorder and Pre-Study on Its Effect / 신경정신의학

OBJECTIVES: We evaluated the design, application, and preliminary effect of a new group therapy program for assisting the psychological adaptation of North Korean refugees with posttraumatic stress disorder (PTSD). METHODS: We recruited 16 female participants from the student body of Hanawon (North Korean refugees) or K city refugee residents, both governed by the Ministry of Unification. Of the participants, 11 scored more than 28 points, the cut-off score, on the MMPI-II PTSD Keane (PK) scale. Another 5 females, who had been diagnosed with PTSD and received treatment, were included in the study. We divided the participants into 2 groups, each of whom participated in group therapy 10 times. Group (A) consisted of 8 Hanawon refugees, while the other group (B) consisted of 8 refugee residents of K City. To examine the therapy's effects, we utilized the Beck Depression Inventory, Beck Anxiety Inventory, Self-esteem Scale, and Impact of Event Scale-Revised, both before and after treatment. We analyzed the results using paired t-tests and repeated measures. RESULTS: Anxiety scores decreased significantly in group A after the group therapy (t=5.04, pbeta.01 ; t=5.44, pbeta.01). In Group B, there were no statistically significant changes on any scales after the treatment. Furthermore, there were no significant differences between the two groups on any measures, but group A showed lower mean SES scores and higher mean BDI and BAI scores than did group B. CONCLUSION: This was a preliminary application of this newly designed group therapy program for aiding the psychological adaptation of North Korean refugees, utilizing a small group of refugees with PTSD. In spite of many shortcomings and poor results, we expect further refinement and research of into treatment modalities despite this challenging developments.

Lived Experience of Psychological Suffering among the North Korean Refugees: Applied to Parse's Human Becoming Research Methodology / 정신간호학회지

PURPOSE: This study is to understand experienced trauma of North Korea refugees before entering in South Korean and know how to connect their traumatic experience with the present life. METHODS: 5 members of North Korea refugees were recruited and approved by the producer of phenomenological and heuristic Human Becoming Methodology of Parse in this study. RESULTS: Mental care service for refugees is needed because North Korea refugees were suffered from post traumatic stress for many years after entering South Korea. CONCLUSION: According to the mental health expert, North Korea refugees would be understood in the viewpoint as Human being in the environment and it is necessary to the remedial intervention to maintain their hope of future simultaneously.

A Seven-Year Panel Study on North Korean Defectors Perception and Satisfaction on Life in South Korea / 신경정신의학

OBJECTIVES: North Korean defectors' comprehension of South Korean society and satisfaction with their lives in South Korea both symbolize their adaptation to their new society. The current report is an analysis of three serial panel studies of 200 North Korean defectors who entered South Korea in 2000. METHODS: From February 2009 to March 2009, we interviewed 121 defectors face-to-face. RESULTS: The results showed that the participant's satisfaction level had been relatively well-maintained, and their understanding of the South Korean culture and language had increased. However, their attitudes toward fellow North Korean defectors had worsened. Their satisfaction level with government support for medical care was very low. Gender, age, level of education in North Korea, Communist Party membership, completion of military service, and current employment status had significant influences on their interpretation and understanding of South Korea. CONCLUSION: The results suggest creating North Korean defector self-help groups, strengthening the medical support system, developing programs tailored according to defectors' different backgrounds, gender, age, and educational levels, as well as increasing South Koreans' awareness of these North Koreans through a appropriate campaign, will be necessary for the peaceful unification of the Korean Peninsula.

Mental Health of North Korean Refugees in Protective Facilities in China

OBJECTIVE: This study aims to provide alternative care plans for mental health of North Korean refugees who are in protective facilities in China. METHODS: Personality Assessment Inventory (PAI) was utilized to measure the presence/absence of post traumatic stress disorder (PTSD) among 65 North Korean refugees. RESULTS: The gender differences in PAI t-scores showed that women exhibited meaningfully higher scores largely in anxiety (m=61.85), depression (m=65.23), and schizophrenia (m=60.98). In different age groups, schizophrenia in the 30 age bracket (m=65.23) was meaningfully higher than the teens (m=48.11). Aggression among the treatment features was the highest in the 20 age group (m=59.19) showing higher t-scores than the teens (m=39.67). Duration in the facility affected mental health in that the 3-5 years group (m=63.91) reported the highest in paranoia. Groups of under 1 year and less than 1-3 years showed meaningfully higher scores in nonsupport. The PTSD (including partial PTSD) rate of the group recorded 9.2%. Correlation between the PTSD and PAI scores showed that the full-PTSD group demonstrated higher average scores in negative impression, somatic complaints, anxiety, anxiety-related disorder, depression, paranoia, schizophrenia, antisocial features, suicide ideation, and treatment rejection than the non-PTSD group. CONCLUSION: Mental health of North Korean refugees in China was worse in women, the thirties, and less than 3-5 years in the facility, and it deteriorated as the duration prolonged. To promote better psychological health of North Korean refugees in China, the attention and aid from the protection facilities and domestic and international interests are required.

Clinical Characteristics of Tuberculosis in North Korean Refugees / 결핵및호흡기질환

BACKGROUND: North Korea's economic and public health problems began in the early 1990s as a result of the gradual loss of economic support from its communist allies, combined with an inordinate number of natural disasters. The decline in public health has increased the incidence of tuberculosis in North Koreans and refugees. This study investigated tuberculosis situation in North Korean refugees in order to prepare for the future impact of tuberculosis control in Korea. MATERIAL AND METHODS: From 2001 to 2005, tuberculosis patients among North Korean refugees who were diagnosed before or after arriving in South Korea, based on the official records of OO hospital, were enrolled in this study. The demographic and clinical data of the cases were evaluated retrospectively. RESULTS: A total of 42 TB cases were reviewed during the study period. Of these, 37 (88.1%) cases were pulmonary TB. based on the cases identified among the number of North Korean refugees' arriving each year, the annual incidence of pulmonary TB were 900 per 100,000 in 2004, 700 in 2003, The number of smear-positive patients was 20 (47.6%) and the number of culture-positive patients was 18 (42.9%). Of the M. tuberculosis isolates, 2 cases were found to be susceptible to all anti-TB drugs available, 4 were resistant to isoniazid, and 3 were multi-drug resistant. CONCLUSION: The prevalence of pulmonary TB in North Korean Refugees is high. In addition, North Korean refugees suffer from more severe tuberculosis in bacteriological and radiological aspects.
