본 연구는 "2011년도 전국 노인생활실태 및 복지욕구조사"의 데이터베이스를 이용하여 우리나라 노인들의 자살생각에 영향을 미치는 요인들을 규명하는 것을 주목적으로 한다. 분석표본은 10,003건이다. 본 연구는 기존의 노인자살 선행연구에서 투입되지 않았던 사회적 질 관련 요인을 분석에 포함시켜 노인이 살고 있는 사회적 환경의 질적 수준이 자살생각에 미치는 영향을 분석하였다. 위계적 로지스틱 회귀분석 결과, 남성일 경우, 연령이 낮을수록, 도시에 거주할 경우, 독신가구일 경우, 주관적 생활수준이 낮을수록, 일상생활수행기능이 열악할수록, 노인우울이 심할수록, 자살생각을 더 많이 하는 것으로 나타났다. 사회적 질 관련 변인은 타인으로부터 대화기피, 의견무시, 못들은 척, 짜증, 불평 등의 부정적인 말과 행동을 경험하고 감정을 상한 적이 있다고 응답한 경우가 자살생각에 가장 커다란 영향력을 가지는 변인인 것으로 나타났다. 본 연구결과는 노인자살률을 낮추기 위해서는 노인이 살고 있는 사회적 환경의 질적 수준을 좀 더 관대하고, 따뜻하고, 친절하게 만들어 감으로써 자살생각을 줄이는 것에 우선순위를 둘 때 자살예방정책이 실효성을 거둘 수 있음을 시사한다.

Objective: This study examined the characteristics of suicidal attempters, including pre-hospital patients and those who visited the emergency department. Methods: Suicidal attempters who had been reported to the 119 call center were selected between July 2015 and June 2016. Sex, age, place, methods of suicidal attempt, season, time, and suicide success rate were reviewed in the fire center records. Results: A total 961 suicide attempters were enrolled. Among them, 53.6% were males who had an approximately 2.6 times higher mortality than that of females (9.2%). The most preferred place to commit suicide was the home in both sexes (68.0% in male, 82.8% in female) and the most preferred methods was drug intoxication, particularly pesticide. The method with the highest mortality was hanging and the lowest was self-harm. The season of the highest mortality was spring. The success of suicide and the time variation were similar. Most of the un-transferred patients also selected fatal suicide attempts compared to transfer patients. Conclusion: Unlike previous studies, this study includes information on un-transferred patients. Overall, the probability of death was highest as more than 50 years men chose hanging as a method, which had an influence on the un-transferred patients group.

Purpose: This study investigated the characteristics and treatment outcomes of patients who visited the emergency department due to intoxication and analyzed the impact of the coronavirus disease 2019 (COVID-19) pandemic on their visits. Methods: A retrospective study was conducted using data from the National Emergency Department Information System (NEDIS) on patients who visited the emergency department due to intoxication between January 2014 and December 2020. In total, 277,791 patients were included in the study, and their demographic and clinical data were analyzed. A model was created from 2014 to 2019 and applied to 2020 (i.e., during the COVID-19 pandemic) to conduct a time series analysis distinguishing between unexpected accidents and suicide/self-harm among patients who visited the emergency department. Results: The most common reason for visiting the emergency department was unintentional accidents (48.5%), followed by self-harm/suicide attempts (43.8%). Unexpected accident patients and self-harm/suicide patients showed statistically significant differences in terms of sex, age group, hospitalization rate, and mortality rate. The time series analysis showed a decrease in patients with unexpected accidents during the COVID-19 pandemic, but no change in patients with suicide/self-harm. Conclusion: Depending on the intentionality of the intoxication, significant differences were found in the age group, the substance of intoxication, and the mortality rate. Therefore, future analyses of patients with intoxication should be stratified according to intentionality. In addition, the time series analysis of intentional self-harm/suicide did not show a decrease in 2010 in the number of patients, whereas a decrease was found for unintentional accidents.

Purpose: Suicide ranks among the top causes of death among youth in South Korea. This study aimed to identify the characteristics of suicidal individuals treated at emergency departments between 2011 and 2020. Methods: A retrospective analysis was conducted using data from January 2011 to December 2020 in the Injury Surveillance Cohort, a prospective registry. Patients' sex, age, mortality, methods of self-harm, and previous suicide attempts were analyzed. The methods of self-harm were categorized into falls, asphyxiation, blunt injuries, penetrating injuries, poisoning, and others. Sub-groups with and without poisoning were compared. Results: The proportion of self-harm/suicide attempts increased from 2.3% (2011) to 5.0% (2020). The mortality rate decreased from 10.8% (2011) to 6.3% (2020). Poisoning was the most common method (61.7%). Mortality rates ranged from 42.0% for asphyxiation to 0.2% for blunt injuries. Individuals in their 20s showed a marked increase in suicide/self-harm attempts, especially in the last three years. A large proportion of decedents in their 70s or older (52.6%) used poisoning as a method of suicide. The percentage of individuals with two or more previous attempts rose from 7.1% (2011) to 19.7% (2020). The death rates by poisoning decreased from 7.7% (2011) to 2.5% (2020). Conclusion: Our findings underscore the urgent need for targeted interventions and suicide prevention policies. Managing and reducing suicide and self-harm in emergency settings will require a focus on poisoning, the 10-29 age group, and the elderly. This paper will be valuable for future policies aiming to reduce the societal burden of suicide and self-harm.

Objective The suicide rate in South Korea is very high and is expected to increase in coming years. Intoxication is the most common suicide attempt method as well as one of the common reason for presenting to an emergency medical center. We used decision tree modeling analysis to identify predictors of risk for suicide by intentional intoxication. Methods A single-center, retrospective study was conducted at our hospital using a 4-year registry of the institute from January 1, 2013 to December 31, 2016. Demographic factors, such as sex, age, intentionality, therapeutic adherence, alcohol consumption, smoking status, physical disease, cancer, psychiatric disease, and toxicological factors, such as type of intoxicant and poisoning severity score were collected. Candidate risk factors based on the decision tree were used to select variables for multiple logistic regression analysis. Results In total, 4,023 patients with intoxication were enrolled as study participants, with 2,247 (55.9%) identified as cases of intentional intoxication. Reported annual percentages of intentional intoxication among patients were 628/937 (67.0%), 608/1,082 (56.2%), 536/1,017 (52.7), 475/987 (48.1%) from 2013 to 2016. Significant predictors identified based on decision tree analysis were alcohol consumption, old age, psychiatric disease, smoking, and male sex; those identified based on multiple regression analysis were alcohol consumption, smoking, male sex, psychiatric disease, old age, poor therapeutic adherence, and physical disease. Conclusion We identified important predictors of suicide risk by intentional intoxication. A specific and realistic approach to analysis using the decision tree modeling technique is an effective method to determine those groups at risk of suicide by intentional intoxication.

Background: External-cause mortality is an important public health issue worldwide. Considering its significance to workers' health and inequalities across industries, we aimed to describe the state of external-cause mortality and investigate its difference by industry in Republic of Korea based on data for 2018. Methods: Data obtained from the Statistics Korea and Korean Employment Information System were used. External causes of death were divided into three categories (suicide, transport accident, and others), and death occurred during employment period or within 90 days after unemployment was regarded as workers' death. We calculated age- and sex-standardized mortalities per 100,000, standardized mortality ratios (SMRs) compared to the general population and total workers, and mortality rate ratios (RRs) across industries using information and communication as a reference. Correlation analyses between income, education, and mortality were conducted. Results: Age- and sex-standardized external-cause mortality per 100,000 in all workers was 29.4 (suicide: 16.2, transport accident: 6.6, others: 6.6). Compared to the general population, all external-cause and suicide SMRs were significantly lower; however, there was no significant difference in transport accidents. When compared to total workers, wholesale, transportation, and business facilities management showed higher SMR for suicide, and agriculture, forestry, and fishing, mining and quarrying, construction, transportation and storage, and public administration and defense showed higher SMR for transport accidents. A moderate to strong negative correlation was observed between education level and mortality (both age- and sex-standardized mortality rates and SMR compared to the general population). Conclusion: Inequalities in external-cause mortalities from suicide, transport accidents, and other causes were found. For reducing the differences, improved policies are needed for industries with higher mortalities.

최근 한국사회에서는 자살률이 급증하고 있다. 자살이 사망원인에서 차지하는 비중도 높아지고 있고 중요 사인에서 자살의 순위도 높아지고 있다. 특히 최근 자살률의 특징의 하나는 고령 자살률이 급증하고 있다는 점이다. 고령 사망순위에서 자살의 순위는 높지 않지만 고령 자살률의 증가 폭은 다른 연령대의 자살률보다 월등히 높다. 이 연구는 한국사회에서 일어나고 있는 자살을 기술적인 수준에서 상세히 밝히고 있다. 특히 일본의 자료를 이용하여 한국과 일본의 자살의 경향을 비교하면서 한국의 최근 자살의 특성이 무엇인지를 객관적으로 보여주고 있다. 자살의 원인에 대해서는 명확한 규명이 이루어지지 않고 있다. 이 연구에서는 최근 자살의 급증이 경제적인 이유에 기인하고 있는 것인지 확인하기 위해서 경제성장률, 실업률, 소득분배, 가계부실지수 등의 경제지표와 전체자살률, 고령 자살률, 각 연령 자살률과의 관계를 1990년부터 1997년까지, 1998년부터 2004년까지로 시기를 나누어 상관관계 계수를 구해 살펴보았다. 분석결과 1997년까지는 자살률과 경제지표 사이에 상관관계가 없었다. 그러나 1998년부터 2004년 사이에는 자살률과 소득분배 지표 사이에 확실한 상관관계가 나타났다. 연령별 자살률로 나누어보면 10대와 20대의 자살률을 제외한 거의 모든 연령층에서 자살률과 소득분배 지표 사이에 강한 상관관계가 존재하는 것으로 나타났다. 이 연구결과는 최근 한국사회의 양극화 현상이 급증하는 자살과 깊은 관계를 가지고 있는 것으로 추론되었다. 경제성장률이나 실업률은 자살과 통계적으로 유의미한 관계가 없는 것으로 나타나기 때문에 모든 경제적 상황의 변화가 자살과 관련이 있는 것이 아니라 소득분배 악화 현상인 경제적 양극화가 자살률의 급증과 깊은 관계가 있는 것으로 생각된다. 낮으며 적극적 활동성과 디지털 성향이 높은 여고생이 의복태도 변인 중 유행을 추구하였고, 외모에 대한 욕구와 동조가 높고, 적극적 활동성과 물질지향성이 높은 여고생이 의복의 성적매력성을 중요시하였다. 외모에 대한 가치와 욕구가 높고, 적극적 활동성과 성취지향성이 높으며, 가정지향성이 낮은 여고생이 의복의 개성/자기표현을 중요시하였으며, 외모에 대한 가치와 욕구가 높고, 성취지향성과 적극적 활동성이 높으며 가정지향성이 낮은 여고생이 의복의 심미성에 관심이 높았다. 외모에 대한 가치와 욕구, 동조가 낮고, 물질지향성과 적극적 활동성이 낮으며 가정지향적인 여학생이 의복의 정숙성에 관심이 높았다. 결론적으로 중 고등학교 여학생의 라이프스타일, 외모에 대한 태도와 의복태도는 밀접한 관련이 있음을 알 수 있었다.안정성에 차이는 없었으나, 신전 위에서 고정하는 것이 과도한 이식 건의 장력으로 인한 슬관절 굴곡 구축을 예방하는데 도움이 될 것으로 사료된다.라 증가할 것으로 추정되었으며 이에 대한 연근 추출물 경구 투여가 간 조직을 보호할 수 있는지를 확인하기 위해 분리한 혈청으로부터 ALT 함량을 측정한 결과 대조군에 비하여 유의한 감소를 나타내었다. 또한 연근 추출물이 혈청 내 지질 과산화물의 생성을 억제할 수 있다면 질병의 예방과 치료에 효과적일 것으로 추정할 수 있으므로 그 생성량을 측정하여 보았으나 대조군과의 차이가 나타나지 않았다. 이상의 결과들을 종합하여 보면 스트레스가 부하된 5일 동안 연근(蓮根) 추출물을 함께 투여한 결과 혈청 corticosterone 함량을 유의하게 감소시켰고 뇌 조직내 noradrenaline 함량을 증가시키는 경향을 나타내어 스트레스 해소에 도움이 될 수 있음을 시사하였다. 또한 혈청 내 ALT 함량을 유의하게 감소시켜 스트레스로 인해

Purpose: This study was conducted to analyze the annual trends and characteristics of work-related mental disorders including suicide among Korean workers. Methods: Employing the Industrial Accident Compensation Insurance (IACI) data collected by the Korea Worker's Compensation & Welfare Service, we analyzed total work-related mental disorders and suicide cases (n=455) claimed to IACI from 2008 to 2012. We paid a special attention to workers' socioeconomic status and occupational characteristics. Results: The number of injured workers and industrial accident rate decreased during the study period, whereas the case of work-related mental disorders showed significant increase. Mental disorders cases were more prevalent in workers who were male, aged the 40s, and engaged in finance, as well as with 1-5 years of working duration than their respective counterparts. Increasing trend of suicide cases was statistically significant by the Cochran-Mantel-Haenszel test (p=.002). Conclusion: This study suggests that work-related mental disorder management strategy and system should be established.
