Suicide in young people aged 15-24: a psychological autopsy study

BACKGROUND: The suicide rate in young people in the United Kingdom has increased over the last decade. As there is a paucity of information about the characteristics of young suicides we have undertaken a detailed investigation of suicides in people aged 15-24 years by means of the psychological autopsy approach. METHODS: The sample consisted of 27 subjects (25 males, two females) whose deaths received a verdict of suicide (N=24) or undetermined cause (N=3). Information was collected from informant interviews, coroners' inquest notes, medical records and psychiatric case notes. A sub-sample of 22 male subjects was compared with an age-matched sample of male deliberate self-harm (DSH) patients. RESULTS: Psychiatric disorders were diagnosed in 19 (70.4%) subjects. These were most commonly depressive disorders (55.5%). Very few individuals were receiving treatment for their disorders. Substance abuse disorders were uncommon but a substantial proportion of individuals had problems with alcohol or drug misuse. Personality disorders were present in 29.6% of subjects and disorders or personality trait accentuation in 55.6%. Comorbidity of psychiatric disorders was found in a third of subjects. The suicides were often the end-point of long-term difficulties extending back to childhood or early adolescence. In addition to mental disorders, relationship and legal difficulties were identified as relatively common contributory factors to the suicides. In comparison to deliberate self-harm patients, male suicides were more likely to use dangerous methods and live alone. LIMITATIONS: Several potential informants could not be interviewed and there was no general population control sample. CONCLUSIONS: The process leading to suicide in young people is often long term, with untreated depression in the context of personality and/or relationship difficulties being a common picture at the time of death. The prevention of suicide in the young clearly requires multiple strategies.     

Suicides and serious suicide attempts: two populations or one?

BACKGROUND: Few studies have examined the extent to which populations of suicides and attempted suicides are similar, or different. This paper compares suicides and serious suicide attempts in terms of known risk factors for suicidal behaviour. METHODS: Using case-control methodology, risk factors for suicidal behaviour were examined in 202 individuals who died by suicide, 275 individuals who made medically serious suicide attempts and 984 randomly selected control subjects. Based on data from significant others, measures used spanned sociodemographic factors, childhood experiences, psychiatric morbidity and psychiatric history, exposure to recent stressful life events and social interaction. RESULTS: Multiple logistic regression identified the following risk factors that were common to suicide and serious suicide attempts: current mood disorder; previous suicide attempts; prior outpatient psychiatric treatment; admission to psychiatric hospital within the previous year; low income; a lack of formal educational qualifications; exposure to recent stressful interpersonal, legal and work-related life events. Suicides and suicide attempts were distinguished in the following ways: suicides were more likely to be male (OR = 1.9, 95% CI 1.1, 3.2); older (OR = 1.03, 95% CI 1.02, 1.04); and to have a current diagnosis of non-affective psychosis (OR = 8.5, 95% CI 2.0, 35.9). Suicide attempts were more likely than suicides to have a current diagnosis of anxiety disorder (OR = 3.5, 95% CI 1.6, 7.8) and to be socially isolated (OR = 2.0, 95% CI 1.2, 3.5). These findings were confirmed by discriminant function analysis, which identified two functions that described the three subject groups: the first function discriminated the two suicide groups from control subjects on a dimension corresponding to risk factors for suicide; the second function discriminated suicide from suicide attempt subjects on a series of factors including gender, non-affective psychosis and anxiety disorder. CONCLUSIONS: Suicides and medically serious suicide attempts are two overlapping populations that share common psychiatric diagnostic and history features, but are distinguished by gender and patterning of psychiatric disorder.     

Suicide and attempted suicide among older adults in Western Australia

BACKGROUND: Suicide rates are high in later life. Risk factors include male sex and depressive illness. This study investigated the relationship between suicidal behaviour and contact with mental health services among the elderly in Western Australia. METHODS: Record linkage was used to obtain records of hospital admissions and mental health service contacts for all suicide attempts and deaths in the period 1980-95. Standardized incidence ratios were calculated for the elderly, general population and people with mental health service contacts. Cox regression was used to evaluated potential risk factors for elderly people who were in contact with mental health services. RESULTS: People over 60 years of age accounted for 15% of suicides and 4.6% of attempted suicides. Suicide rates were 3.3 times higher in males and 4.4 times higher in females when compared to the general population of elderly people. For attempted suicide, the rate was 5.8 times higher in males and 6.6 times higher in females with prior contact with mental health services. Highest risk of suicide was found in patients with diagnoses of affective psychoses (RR = 3.7), adjustment reaction (RR = 3.2) or depressive disorder (RR = 2.8). The diagnosis of cancer was associated with decreased risk of suicide (RR = 3.6) and attempted suicide (RR = 1.9). CONCLUSIONS: Suicide rates are high among the elderly in Western Australia. Suicide is significantly associated with the diagnosis of mood disorder. Suicide attempts are less common, and are associated most strongly with mood and personality disorders. The decreased risk of self-harm behaviour among patients with cancer warrants further investigation.     

A case-control study of 92 cases of in-patient suicides

BACKGROUND: A significant number of patients committed suicide while receiving in-patient treatment in psychiatric hospitals. Most previous studies on psychiatric in-patient suicides were conducted in the West. This study aimed to describe the characteristics and identify risk factors of suicides occurring during psychiatric in-patient care in Hong Kong. METHOD: The case record data of suicide cases (Coroner's verdicts of suicides and undetermined deaths) from all public psychiatric hospitals in the entire region within a 3 years' period (N=93) were compared with matched controls. RESULTS: In-patient suicide rate was 269/100,000 admissions. Majority had schizophrenia. Suicide usually occurred after the first month of admission, during leave, and by jump from heights. There were little case-control differences in treatment received. Multiple conditional logistic regression found 5 risk factors: previous history of deliberate self-harm (OR=4.60, 95% CI=1.57-13.5); admitted because of suicidal behaviour (OR=3.92, 95% CI=1.3-11.9); depressive symptoms at time of suicide (OR=8.53, 95% CI=1.4-52); away without leave at anytime during index admission (OR=17, 95% CI=1.76-163); and extrapyramidal side effects/akathisia at time of suicide (OR=10.8, 95% CI=1.75-66.7). LIMITATIONS: Retrospective case record review depended on non-standardized and variable quality of case notes entry. Matching for hospitals in this study would make the comparison between hospitals impossible. Although this is the second largest case-control study of psychiatric in-patient suicide, the estimated power suggested subtle risk factors would be missed. CONCLUSION: Majority of in-patient suicides occurred at a time of perceived low risk. A high sensitivity to the risk of suicide and vigorous treatment of depressive symptoms were indicated. The care processes during the index admission could bear strong influences on the risk of in-patient suicides.     

Current psychiatric morbidity, aggression/impulsivity, and personality dimensions in child and adolescent suicide: a case-control study

OBJECTIVE: The present study was designed to evaluate psychiatric risk factors for child and adolescent suicide, and to determine the association between impulsive-aggressive and other personality traits, and suicide completion in this population. METHOD: Psychiatric diagnoses, impulsive-aggressive and other personality traits were assessed in 55 child and adolescent suicide victims and 55 community controls using semi-structured proxy-based interviews and questionnaires. RESULTS: The most significant psychiatric risk factors associated with child and adolescent suicide were depressive disorders (OR=48.414, 95% CI 6.247-375.185), substance/alcohol abuse disorder (OR=5.365, 95% CI 1.434-20.076), and disruptive disorders (OR=13.643, 95% CI 2.292-23.16). Additionally, suicide victims showed higher scores on lifetime aggression/impulsivity, and harm avoidance. However, after logistic regression, the only independent significant predictors of suicide in this age group were the presence of depressive disorders (Adjusted OR (AOR)=39.652, 95% CI 4.501-349.345), substance/alcohol abuse disorders (AOR=7.325, 95% CI 1.127-47.62), and disruptive disorders (AOR=6.464, 95% CI 1.422-29.38). LIMITATIONS: Relatively small sample size, and cross-sectional design. CONCLUSIONS: Our findings confirm the existence of a particular clinical profile of children and adolescents at high risk for suicide. Additionally, our results reinforce the need for improved understanding of the interrelationships between stressors, depression, substance/alcohol abuse disorders, disruptive disorders and personality traits/dimensions in youth suicidal behavior.     

Suicidal behaviour among primary-care patients with depressive disorders

BACKGROUND: Most national suicide prevention strategies set improved detection and management of depression in primary health care into a central position. However, suicidal behaviour among primary-care patients with depressive disorders has been seldom investigated. METHOD: In the Vantaa Primary Care Depression Study, a total of 1119 primary-care patients in the City of Vantaa, Finland, aged 20 to 69 years, were screened for depression with the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire. Depressive disorders were diagnosed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), and the 137 patients with depressive disorder were included in the study. Suicidal behaviour was investigated cross-sectionally and retrospectively in three time-frames: current, current depressive episode, and lifetime. Current suicidal ideation was measured with the Scale for Suicidal Ideation (SSI), and previous ideation and suicide attempts were evaluated based on interviews plus medical and psychiatric records. RESULTS: Within their lifetimes, 37% (51/137) of the patients had seriously considered suicide and 17% (23/137) attempted it. Lifetime suicidal behaviour was independently and strongly predicted by psychiatric treatment history and co-morbid personality disorder, and suicidal behaviour within the current episode was predicted most effectively by severity of depression. CONCLUSIONS: Based on these findings and their convergence with studies of completed suicides, prevention of suicidal behaviour in primary care should probably focus more on high-risk subgroups of depressed patients, including those with moderate to severe major depressive disorder, personality disorder or a history of psychiatric care. Recognition of suicidal behaviour should be improved. The complex psychopathology of these patients in primary care needs to be considered in targeting preventive efforts.     

One-month prevalence of depression and other DSM-IV disorders among young adults.

BACKGROUND: We aimed to provide prevalence data on depression and other current mental disorders, impairment, need of psychiatric care and use of mental health services among young adults. METHODS: Based on a semi-structured clinical interview, current DSM-IV disorders, impairment, need of psychiatric care and use of mental health services were evaluated in a sample of 20-24-year-old young urban adults (N = 245), mean age 21.8, screened from a baseline population of 706. One-month prevalence estimates for disorders were calculated by the double sampling method, using various additional criteria to identify cases. RESULTS: One in four young adults (23.8%) suffered from a current mental disorder, the most prevalent being depressive (10.8%), anxiety (6.9%), substance use (6.2%) and personality disorders (6.0%). Prevalence estimates varied substantially according to the use of additional diagnostic criteria. Impairment (GAF < 61) together with DSM-IV symptom criteria produced an overall disorder prevalence of 10.3%, and 5.5% for depression. Prevalences were higher for females than males, except for alcohol abuse and personality disorders. Current co-morbidity was found in 39% of subjects with any disorder, and in more than half of those with depression. One-third of subjects with a current disorder reported an associated contact with psychiatric services and 16% had an ongoing contact. CONCLUSIONS: Our findings support the use of additional criteria to produce clinically relevant prevalence data. Co-morbidity should receive special attention due to its amplification of both need for psychiatric care and severity of impairment. Finally, our results show disturbed young adults to be severely undertreated.     

A case-control study of tattoos in young suicide victims as a possible marker of risk

BACKGROUND: The goal was to examine tattooing in suicides, as tattoos have been associated with several risk factors for suicide. METHOD: A chart review of a three-year sample of 134 consecutive suicides in Mobile County, Alabama, was conducted. The prevalence of tattoos was compared between young (<30) white suicides and accidental deaths matched for age, gender and race, in a case-control study. RESULTS: Tattoos were found in 21% of suicides. Fifty-seven percent of young white suicides were tattooed compared to 29% of matched accidental deaths. LIMITATIONS: Findings are preliminary due to the small sample size. The study methodology precluded obtaining information of psychiatric diagnoses prior to death. CONCLUSIONS: Tattoos may be possible markers for lethality from both suicide and accidental death in young people, presumably because of shared risk factors such as substance abuse and personality disorder. Affective disorders should receive further, more specific studies. The clinical value of inquiring about tattoos in young people at risk of suicide needs further study.     

Role of doctors in the prevention of suicide: the final consultation.

BACKGROUND. It is generally assumed that people committing suicide see their doctor shortly before their death, and consequently that enhancing doctors' psychiatric knowledge and interview skills might help prevent some suicides. AIM. A study was undertaken to determine the nature and timing of final contacts with medical practitioners by people committing suicide. METHOD. Adults dying by suicide in Scotland during 1988-89 were identified by the General Register Office for Scotland and their primary care case notes studied. RESULTS. Within this national sample, medical contact near to the time of the suicidal act was rare, except for those individuals who had a previous psychiatric history. CONCLUSION. These data suggest that medical practitioners, particularly those working in primary care, are not failing to detect and intervene in significant numbers of preventable suicides. Consequently, the likelihood of implementing successful suicide prevention strategies based within primary care is open to question. Greater awareness of the risk of eventual suicide in those with a previous history of psychiatric disorder may contribute to any future reduction in suicide rates.     

Mental healthcare status and psychiatric diagnoses of train suicides

BACKGROUND: The objective of this study is to investigate mental healthcare status and psychiatric disorders in train suicides. METHODS: Data of 4 published train suicide studies were combined with a study of 57 train suicides in The Netherlands. RESULTS: 53% of all train suicides received psychiatric care at the time of suicide, with 49% of them being inpatients. These values are higher than those found in general suicides. When compared to general suicides, functional non-affective psychoses are overrepresented by 25% vs 14%. The percentage of affective disorders approximates that of general suicides namely: 39% vs 42%. "Other diagnoses" are underrepresented by 23% vs 40%. LIMITATIONS: All psychiatric diagnoses were based on clinical data, which may not accurately reflect the patient's psychiatric condition at the time of suicide. CONCLUSIONS: Train suicides receive mental healthcare more often than general suicides and are more often characterized by severe psychopathology. The study indicates that patients with affective and psychotic disorders in particular should be targeted in order to prevent train suicide.     

Suicidal ideation and suicide attempts among child and adolescent psychiatric inpatients in Finland

BACKGROUND: The aim was to study the prevalence of, and factors associated with, suicidal ideation and suicide attempts among child and adolescent inpatients during hospital treatment. METHODS: The target group included all the child and adolescent psychiatric inpatients (n=504) in Finland on a chosen day. Suicidality was determined by the psychiatrist responsible for the inpatient treatment, using a questionnaire also exploring demographic, diagnostic, and treatment characteristics, as well as traumatic events of the patient. RESULTS: The rate of suicidal ideation was 37.6%, and suicide attempts 10.8%. The factors independently associated with suicidal ideation in multivariate analysis were the following: being affected by open adult sexual behaviour (OR 3.2), having depression (OR 2.5) or conduct disorder (OR 2.4) diagnosis, and manifesting violent acts (OR 2.4). The factors independently associated with suicide attempts were: manifesting violent acts (OR 8.1), having depression diagnosis (OR 5.3), being affected by open adult sexual behaviour (OR 4.9), involuntary treatment (OR 4.7), and being of the female sex (OR 3.7). Suicidal ideation was particularly prevalent among boy patients having conduct disorders, manifesting violent acts, and belonging to the age group under 13 years old. Suicide attempts were particularly prevalent among depressive adolescent girl patients. LIMITATIONS: Suicidality was based solely on the clinician's evaluation. CONCLUSIONS: Suicidal ideation and suicide attempts are common among child and adolescent psychiatric inpatients. Particular attention should be directed to inpatients who manifest violent acts or have depressive disorder.     

Suicide at 50 years of age and older: perceived physical illness, family discord and financial strain

BACKGROUND: Mental disorders amplify suicide risk across the lifecourse, but most people with mental disorder do not take their own lives. Few controlled studies have examined the contribution of stressors to suicide risk. METHOD: A case-control design was used to compare 86 suicides and 86 controls aged 50 years and older, matched on age, gender, race and county of residence. Structured interviews were conducted with proxy respondents for suicides and controls. RESULTS: Perceived physical illness, family discord and employment change amplified suicide risk after controlling for sociodemographic covariates and mental disorders that developed > or = 1 year prior to death/interview. Only the effect of physical illness (OR 6.24, 95% CI 1.28-51.284) persisted after controlling for all active mental disorders. CONCLUSIONS: Interventions to decrease the likelihood of financial stress and to help families manage discord and severe physical illness may effectively reduce suicides among middle-aged and older adults.     

Suicide and occupation: the impact of socio-economic, demographic and psychiatric differences

BACKGROUND: To explore the risk of suicide associated with occupation while evaluating the impact of socio-economic, demographic and psychiatric differences. METHOD: A nested case-control study with 3195 suicides and 63 900 matched controls. Information on causes of death, occupation, psychiatric admission, marital status and socio-economic factors was obtained from routine registers. RESULTS: Across the 55 occupations investigated, the risk of suicide ranged from 2.73 [95% confidence interval (CI) 1.77-4.22] among doctors to 0.44 (95% CI 0.27-0.72) among architects and engineers compared with primary school teachers. With the exception of doctors and nurses, most of the excess risk of suicide associated with particular occupations is explained by the social and economic characteristics of people in those occupations. Much, but not all, of the excess risk in doctors and nurses is due to their increased use of self-poisoning, a method for which they have the knowledge to use effectively. Occupation has little association with suicide among people who suffer from a psychiatric illness, except for doctors, where the excess risk is 3.62 (p=0.007). CONCLUSIONS: Most of the considerable variation in suicide risk across occupations is explained by socio-economic factors, except for doctors and nurses. Apart from in doctors, the risk of suicide has little association with occupation among people who suffer from a psychiatric illness. Restriction of access to lethal means is an important strategy in suicide prevention.     

Suicide and undetermined death in south east Scotland. A case-control study using the psychological autopsy method

BACKGROUND: Mental disorders are major risk factors for suicide. Not all those who suffer from mental disorders kill themselves. Additional information is required to differentiate higher and lesser risk patients. METHODS: Retrospective case-control comparison was made of cases of suicide/undetermined death with living controls using psychological autopsy in South East Scotland. Cases and controls were matched for age, sex and mental disorder. Informants were those closest to cases and controls. The subjects were 45 cases of suicide/undetermined death and 40 living controls. RESULTS: Cases and controls did not differ significantly in severity of mental disorder. The main factors independently associated with undetermined death or suicide were: a history of deliberate self-harm (adjusted OR 4 1); physical ill health (adjusted OR 7.8); and engagement by mental health services (adjusted OR 0.01). Other antecedents associated with increased risk (criminal record, police involvement, financial problems and failure to vote) and those associated with decreased risk (contact with a doctor and in-patient care) did not exert effects after controlling for confounding. CONCLUSIONS: Controls were receiving more care of whatever kind. Treatment of mental disorder comorbid with physical illness and a history of deliberate self-harm may be especially important. Factors that separate those with mental disorder at high risk from those at lesser risk relate to care levels provided, which may be a function of engagement by and with health services. The role of mental health professionals is beneficial in suicide prevention. The focusing of that role towards engaging alienated or 'difficult' patients should be addressed.     

Suicide in current psychiatric in-patients: a case-control study The National Confidential Inquiry into Suicide and Homicide

BACKGROUND: Few controlled studies have investigated factors associated with suicide in current in-patients. We aimed to identify psychosocial, behavioural and clinical risk factors, including variations in care, for in-patient suicide. METHOD: We conducted a national population-based case-control study of people who died by suicide between 1 April 1999 and 31 December 2000 while in psychiatric in-patient care in England. Cases were 222 adult mental health in-patients who died by suicide matched on date of death with 222 living controls. RESULTS: Nearly a quarter of suicides took place within the first week of admission; most of these died on the ward or after absconding. After the first week, however, most suicides occurred away from the ward, the majority of patients having left the ward with staff agreement. Previous deliberate self-harm, recent adverse life events, symptoms of mental illness at last contact with staff and a co-morbid psychiatric disorder were associated with increased risk for suicide. Being off the ward without staff agreement was a particularly strong predictor. Those patients who were detained for compulsory treatment were less likely to die by suicide. Independent predictors of in-patient suicide were male sex, a primary diagnosis of affective disorder and a history of self-harm. Being unemployed or on long-term sick leave appeared to be independently protective. CONCLUSION: Prevention of in-patient suicide should emphasize adequate treatment of affective disorder, vigilance in the first week of admission and regular risk assessments during recovery and prior to granting leave. Use of compulsory treatment may reduce risk.     

Personality disorders and health problems distinguish suicide attempters from completers in a direct comparison

Background

Whether suicide attempters and completers represent the same population evaluated at different points along a progression towards suicide death, overlapping populations, or completely different populations is a problem still unresolved.

Methods

446 Adult suicide attempters and knowledgeable collateral informants for 190 adult suicide probands were interviewed. Sociodemographic and clinical data was collected for both groups using semi-structured interviews and structured assessments. Univariate analyses and logistic regression models were conducted to explore the similarities and differences between suicide attempters and completers.

Results

Univariate analyses yielded significant differences in sociodemographics, recent life events, impulsivity, suicide intent, and distribution of Axis I and II disorders. A logistic regression model aimed at distinguishing suicide completers from attempters properly classified 90% of subjects. The most significant variables that distinguished suicide from attempted suicide were the presence of narcissistic personality disorder (OR=21.4; 95% CI=6.8–67.7), health problems (OR=20.6; 95% CI=5.6–75.9), male sex (OR=9.6; 95% CI=4.42–20.9), and alcohol abuse (OR=5.5; 95% CI=2.3–14.2).

Limitations

Our study shares the limitations of studies comparing suicide attempters and completers, namely that information from attempters can be obtained from the subject himself, whereas the assessment of completers depends on information from close family or friends. Furthermore, different semi-structured instruments assessed Axis I and Axis II disorders in suicide attempters and completers. Finally, we have no data on inter-rater reliability data.

Conclusions

Suicide completers are more likely to be male and suffer from alcohol abuse, health problems (e.g. somatic illness), and narcissistic personality disorder. The findings emphasize the importance of implementing suicide prevention programs tailored to suicide attempters and completers.     

Psychiatric and social aspects of suicidal behaviour in prisons

BACKGROUND: Suicidal behaviour and completed suicide are serious problems within British prisons, leading to significant morbidity and mortality, and are the focus of major efforts towards their prevention. AIM: To explore the demographic, social and psychiatric correlates of suicidal behaviour in prisons in England and Wales and their relationship with health service use; and to develop a combined psychosocial model of risk. METHOD: This report analyses the prevalence of suicidal ideation and suicide attempts in the ONS National Prison Survey, and their association with the presence of psychiatric disorders, personality disorder, substance abuse and social risk factors. These data were compared with data from the second national survey of psychiatric morbidity in adults living at home. In both surveys, a two-phase interviewing procedure was used, covering general health, health service use, assessment of psychiatric disorders, life events, social supports, suicidal behaviour, activities of daily living, sociodemographic data, substance abuse and intelligence. RESULTS: Suicidal thoughts and suicide attempts were commoner in prisons than in the general population and these were significantly associated with higher rates of psychosis, neurosis and personality disorder in prisons. In addition, demographic and factors such as being young, single, white, leaving school early and experiencing poor social support and significant social adversity were important risk factors for suicidal thoughts. Crucially, there was no separate category of people at suicidal risk who did not have psychiatric disorders. CONCLUSIONS: The high rates of suicidal behaviour in prisons cannot be addressed without adequate attention to the high rates of psychiatric disorder and vulnerability factors in prisoners.     

Anxiety disorders and the onset of depression among adults in the community

OBJECTIVE: To determine the association between anxiety disorders, panic attack and the risk of major depression among adults in the community. METHOD: Data were drawn from the Epidemiologic Catchment Area Program survey waves 1 (N = 20291) and 2 (N = 15849). Multivariate logistic regression analyses were used to determine the risk of incident major depression at 12-month follow-up (wave 2) associated with each anxiety disorder and panic attacks assessed at wave 1, adjusting for differences in sociodemographic characteristics, and then controlling simultaneously for all anxiety disorders, and other psychiatric co-morbidity. RESULTS: Specific phobia (OR = 1.7 (1.6, 1.8)), agoraphobia (OR = 2.3 (2.2, 2.5)), obsessive-compulsive disorder (OR = 5.4 (5.0, 5.8)) and panic attack (OR = 1.9 (1.8, 2.1)) each made an independent contribution to the risk of major depression, which persisted after adjusting simultaneously for sociodemographic differences and other psychiatric co-morbidity. CONCLUSIONS: Each anxiety disorder and panic attacks appear to confer an independent risk for the onset of major depression within 12-months among adults in the community. Understanding the key role played by anxiety in depression onset is needed for prevention strategies.     

Smoking differently modifies suicide risk of affective disorders, substance use disorders, and social factors

BackgroundAlthough an association between smoking and suicide has repeatedly been shown, information about a modifying influence of smoking on other risk factors for suicide is lacking.MethodsAxis I and Axis II disorders, sociodemographic factors, and tobacco use were assessed by a semi-structured interview including the Structured Clinical Interview for DSM-IV Axis I (SCID-I) and Personality Disorders (SCID-II) in 163 suicides (mean age 49.6 +/? 19.3 years; 64.4% men;) by psychological autopsy method and by personal interview in 396 living population-based control persons (mean age 51.6 +/? 17.0 years; 55.8% men).ResultsSmoking status (current smokers, lifetime non-smokers, and former smokers) differently modifies the effects of psychiatric disorders and sociodemographic variables on suicide risk. Former and current smoking modified suicide risk associated with affective disorders, but only current smoking increased suicide risk for substance use disorders. Ex-smokers with affective disorders, particularly with major depression, had less increased suicide risk than current smokers and non-smokers with affective disorders. Estimated suicide risks for personality disorders and ‘no professional training’ were strongly increased by smoking.LimitationsDue to the small size of some of the subgroups, confidence intervals are wide. Therefore, precise risk estimation is not possible.ConclusionsClinicians should interpret smoking as an indicator of increased risk of suicide for individuals with substance use disorders, personality disorders, and adverse social factors. Further studies are needed to investigate the effects of smoking cessation on suicide risk of patients with psychiatric disorders such as major depression and substance use disorders.     

Prevalence and comorbidity of affective disorders in persons making suicide attempts in Hungary: importance of the first depressive episodes and of bipolar II diagnoses

BACKGROUND: The purpose of this study was to investigate the prevalence and comorbidity of affective disorders, especially current major depressive episode and bipolar disorder among suicide attempters in Hungary. METHODS: Using a structured interview (Mini International Neuropsychiatric Interview) determining 16 Axis I psychiatric diagnoses defined by the DSM-IV and a semistructured interview collecting background information, the authors examined 100 consecutive suicide attempters, aged 18-65. RESULTS: Eighty-eight percent of the attempters had one or more current diagnoses on Axis I. In 69% it was major depressive episode and 60% of them were suffering their first episode. Thirty-five percent of the patients with current major depressive episode had had hypomanic (n=19) or manic (n=5) episodes in the past. Seventy percent of the individuals received two or more current diagnoses on Axis I. Eighty-six percent of all current Axis I disorders (except major depressive episode) were diagnosed together with a current major depressive episode. The diagnosis of current major depressive episode and the number of current psychiatric disorders was significantly and positively related to the number of suicide attempts, but the diagnosis of past major depressive episode was not. LIMITATIONS: This study included suicide attempters who had presented selfpoisoning, but not individuals with very high risk of fatality. CONCLUSIONS: In suicide attempters there is a very high prevalence of affective disorders, especially major depression, first episode of major depression and bipolar II disorder. This study underlines the importance of early detection and treatment of psychiatric disorders for the prevention of suicidal behavior.
