抑郁症未遂自杀及相关因素研究

对１４０例抑郁症患者的未遂自杀及相关因素进行研究，发现未遂自杀发生率为３４．２９％。与对照组相比，发生未遂自杀的４８例有以下特点：年龄较大、多有阳性家族史、个人经济收入较低，发病多有诱因、多为急性起病、ＨＡＭＤ睡眠障碍和绝望感因子分较高、迟缓因子分较低、多为单相抑郁症。逐步回归分析发现，影响未遂自杀的因素主要为ＨＡＭＤ睡眠障碍、绝望感、迟缓因子分。     

冲动性与非冲动性自杀未遂的比较

目的 自杀未遂是我国重要的公共卫生问题,但缺乏针对性的、有效的干预措施。本研究通过比较冲动性与非冲动性自杀未遂的特征,为制定相应的预防措施奠定基础。方法 对4所市县级综合医院的306例病情较重的自杀未遂病人用自制调查表进行调查。按其自杀前考虑自杀时间的长短人为地分为冲动性(≤2小时,164例)和非冲动性(>2小时,142例)两组,并对两组进行比较。结果 两组在许多方面有显著差异。用非条件Logistic回归分析控制不同因素之间的相互影响后,发现在自杀未遂者中,自杀前2周抑郁程度越轻、自杀意图强度越低,有急性(≤1月)负性生活事件、自杀前1个月生命质量越高、居住在乡村、越年轻越易发生冲动性自杀行为;而性别和其他因素与冲动性自杀行为的发生无关。结论 冲动性与非冲动性自杀未遂的特征明显不同,对这两种不同的自杀未遂人群是否应采取不同的预防及干预措施是目前迫切需要解决的问题。     

农村未遂自杀者的再自杀意念及相关因素研究

目的探讨农村未遂自杀者再自杀意念的发生率及其相关因素。方法以乡镇卫生院近2年的抢救记录为调查线索,共完成74例自杀未遂者的调查,对其再自杀意念进行评定,并用SDS和FES对其抑郁症状和家庭环境进行评估,收集其一般资料。结果74例自杀未遂者中有48例(64.86%)有不同程度的再自杀意念,48例有再自杀意念者的SDS得分(42.42±7.64)明显高于26例无再自杀意念者(33.58±9.52)(t=4.35,P<0.001),有再自杀意念组的家庭亲密度、成功性、文化性、娱乐性和组织性均较无再自杀意念组差,家庭矛盾性较对照组突出。多元逐步回归分析显示,影响自杀未遂者再自杀意念的主要危险因素为:家庭成功性、SDS总分和家庭矛盾性。结论64.86%的自杀未遂者在其后的一段时期内仍存在不同程度的再自杀意念,而且再自杀意念主要与患者的家庭环境和患者的抑郁症状有关。     

DST non-suppression predicts suicide after attempted suicide

Most prospective studies of HPA axis have found that non-suppressors in the dexamethasone suppression test (DST) are more likely to commit suicide during the follow-up. Attempted suicide is a strong clinical predictor of suicide. The aim of this study was to assess the predictive value of DST for suicide in a group of depressed inpatients with and without an index suicide attempt. Historical cohort of 382 psychiatric inpatients with mood disorder admitted to the department of Psychiatry at the Karolinska University Hospital between 1980 and 2000 were submitted to the DST and followed up for causes of death. During the follow-up (mean 18 years), 36 suicides (9.4%) occurred, 20 of these were non-suppressors and 16 were suppressors. There was no statistically significant difference in suicide risk between the suppressors and non-suppressors for the sample as a whole. An index suicide attempt predicted suicide. In suicide attempters with mood disorder, the non-suppressor status was significantly associated with suicide indicating that HPA axis hyperactivity is a risk factor for suicide in this group. The dexamethasone suppression test may be a useful predictor within this population.     

Emotional intelligence and problem solving skills in individuals who attempted suicide

AimBased on our clinical observations, low emotional intelligence level and problem-solving skills may have play a role in suicide attempts. The present study is aimed to investigate the emotional intelligence levels and the correlation between problem solving skills and suicide attempts in individuals who already attempted suicide.Material and methodThe study was conducted on twenty-five individuals who attempted suicide and 25 healthy controls with similar sociodemographic characteristics. All participants were asked to fill in the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Problem-Solving Inventory (PSI) and Emotional Intelligence Scale (EIS).FindingsIt was determined that the patient group BAI scores and BDI scores were significantly higher when compared to the control group (p < 0.01, p < 0.01). The total EIS and emotional awareness, emotion management, self-motivation, empathy and relationship control subscale scores of the patient group were significantly lower when compared to the control group (p < 0.01, p < 0.01, p < 0.01, p < 0.01, p = 0.047).PSI scores were significantly higher in the patient group when compared to the control group (p < 0.01). There was a negative correlation between PSI total score and EIS subscale scores.ConclusionIt was observed that these individuals experienced more difficulty in solving problems when compared to healthy individuals, however as their emotional intelligence levels increased, their problem-solving skills increased as well.     

抑郁症的自杀未遂及其危险因素分析

为了获得抑郁症病人的自杀未遂发生率及其危险因素，采用自制的抑郁症与自杀的关系登记表和Ｈａｍｉｌｔｏｎ抑郁量表，分别对符合中国精神疾病分类方案与诊断标准第２版修订本的２１２例住院的抑郁症病人进行调查评分，然后用ＳＰＳＳ和ＰＥＭＳ软件包进行统计分析。结果：在２１２例抑郁症病人中发生自杀观念１５８例（７４．５％），自杀未遂６７例（３１．６％）。在自杀未遂组中的自杀方式以过量服药为主（４７．８％），自杀地点多在室内（７７．６％）。自杀未遂组的抑郁症状评分高于无自杀行为组（ｔ＝７．２７，Ｐ＜０．０１）。自杀与绝望感、抑郁情绪、自卑感、自知力等呈正相关。逐步回归分析发现，绝望感对自杀的影响最大，其次是抑郁情绪，再次是自卑感和自知力。提示抑郁症与自杀的关系密切，频繁出现≥３次自杀观念的抑郁症病人发生自杀行为的可能性较大。     

Cholesterol and the “Cycle of Violence” in attempted suicide

An association between low levels of serum cholesterol and violent or suicidal behaviour has frequently been reported. However the role of serum cholesterol in the cycle of violence (Widom, 1989) has not been studied. The aim of this study was to investigate association between exposure to violence during childhood and used adult violence in suicide attempters with low and high serum cholesterol levels. 81 suicide attempters were assessed with the Karolinska Interpersonal Violence Scale (KIVS) measuring exposure to violence and expressed violent behaviour in childhood (between 6 and 14 years of age) and during adult life (15 years or older). We used median split to dichotomise groups below and above median serum cholesterol. In patients with serum cholesterol below median, the correlation between exposure to violence as a child and used adult violence was significant (rho=0.52, p=0.002), while in patients with serum cholesterol above median, the correlation between exposure to violence as a child and expressed violent behaviour as an adult was not significant (rho=0.25, p=0.2). Comorbid substance abuse predicted violent behaviour as an adult only in patients with serum cholesterol above median. Serum cholesterol may modify the effect of the “Cycle of Violence”.     

Impulsivity and clinical symptoms among adolescents with non-suicidal self-injury with or without attempted suicide

This study examined clinical characteristics and laboratory-measured impulsive behavior of adolescents engaging in either non-suicidal self-injury with (NSSI + SA; n = 25) or without (NSSI-Only; n = 31) suicide attempts. We hypothesized that adolescent with NSSI + SI would exhibit more severe clinical symptoms and higher levels of behavioral impulsivity compared to adolescents with NSSI-Only. Adolescents were recruited from an inpatient psychiatric hospital unit and the two groups were compared on demographic characteristics, psychopathology, self-reported clinical ratings, methods of non-suicidal self-injury, and two laboratory impulsivity measures. Primary evaluations were conducted during psychiatric hospitalization, and a subset of those tested during hospitalization was retested 4–6 weeks after discharge. During hospitalization, NSSI + SA patients reported worse depression, hopelessness, and impulsivity on standard clinical measures, and demonstrated elevated impulsivity on a reward-directed laboratory measure compared to NSSI-Only patients. In the follow-up analyses, depression, hopelessness, suicidal ideation, and laboratory impulsivity were improved for both groups, but the NSSI + SA group still exhibited significantly more depressive symptoms, hopelessness, and impulsivity than the NSSI-Only group. Risk assessments for adolescents with NSSI + SA should include consideration not only of the severity of clinical symptoms but of the current level impulsivity as well.     

Sex differences in risk factors for suicide after attempted suicide

Abstract.Aim: This study aims to investigate suicide risk factors after attempted suicide and whether and how these risk factors differ between the sexes.Method: A total of 1052 suicide attempters admitted to the Medical Emergency Inpatient Unit, Lund University Hospital, Sweden were followed up concerning suicide and death from other causes after a median period of 6 years and 5 months. In all, 50 persons committed suicide during follow-up. At the index suicide attempt, socio-demographic data and information about clinical characteristics were gathered in a standardised manner. Risk factors were identified among these data using survival analyses for the whole sample and for each sex separately.Result: Men had a higher frequency of suicide and a greater overall mortality than women. Cox regressions showed that suicide attempt(s) prior to the index attempt and the use of a violent method for the index attempt were risk factors for men only, whereas older age and a high suicidal intent (Beck SIS score) were female ones. Major depression was a risk factor for both sexes.Conclusion: More attention probably needs to be paid to the importance of gender in assessment of suicide risk and treatment of suicide attempters.
