Suicide and mental disorders

Abstract In Japan, there has not yet been a complete psychological autopsy study. The author conducted a retrospective study of failed suicides (quasi-completed suicides) admitted to an emergency critical care center. According to the lethality of suicide methods, 133 out of 265 subjects over 6 years (1986–1991) were classified as the absolutely dangerous (AD; the failed suicides) group. As a principal diagnosis, psychoses, endogenous depression, substance abuse were present in 75% of the AD group. The diagnostic distribution largely differed with depressive disorders being mainly in the older group (50+ years), and psychoses predominating in the younger group (<30 years). This study suggested that the majority of suicide victims in Japan also had mental disorders, and suicide prevention should be confronted with this clinical fact.     

San Diego suicide study. I. Young vs old subjects

The suicide rate among people under 30 years of age has nearly tripled in the past several decades. We compared 133 suicides under the age of 30 years with 150 aged 30 years and over. After gathering and reviewing extensive clinical information and postmortem toxicologic data, we assigned diagnoses using DSM-III criteria. A major diagnostic finding was the occurrence of more drug abuse than had been previously reported, significantly more often in the young people. Few other differences were found either between our total sample and previous studies or between our younger and older groups. We conclude that a closer look at the young group is necessary to see what other differences might occur between the drug abusers and other young suicides.     

Treatment of depression in children and adolescents

Depression occurs in children and adolescents, although it may appear differently in younger patients. Research suggests juvenile depression may respond to psychotherapy and to pharmacologic agents, and that antidepressants remain a valuable treatment for juveniles with depression. Diagnostic considerations in juveniles with mood symptoms are discussed. A brief overview is provided of the evidence supporting psychotherapy for juveniles with depression. Controlled antidepressant trials in juveniles with depression provide some support for the use of some selective serotonin reuptake inhibitors and little support for atypical antidepressants, tricyclic antidepressants, or monoamine oxidase inhibitors. Evidence from suicide rates over time, autopsy findings among juvenile suicides, and impacts of antidepressant prescribing trends are related to the current controversy over suicidality and antidepressant use in juvenile patients. Based on this evidence, practical guidelines for treatment of juvenile depression are provided.     

Suicide or accident? a psychological autopsy study of suicide in youths under the age of 16 compared to deaths labeled as accidents

ABSTRACT: OBJECTIVE: In the present paper, we describe suicide in youths under 16 years of age and compare their risk factors for suicide to those of older adolescents as described in the literature. Furthermore, we evaluate the possible mislabeling of suicides as accidents, and vice versa. METHOD: We used the data from a nationwide psychological autopsy of youths 15 years and younger who had committed suicide or died in accidents in Norway from 1993 to 2004 (n = 84). We additionally constructed a suicide index to distinguish between the two causes of death. RESULTS: The young suicide victims presented, with little gender difference, fewer obvious risk factors and less suicide intent than commonly described for older adolescents. The suicide index distinguished quite well between suicides and accidents, with few cases indicating a possible mislabeling, although some suicide cases could have been labeled as uncertain. CONCLUSION: In line with previous research, suicides in 11-15-year-olds have many similarities to suicides in older adolescents in terms of external circumstances, but they present less apparent warning signs. In our total sample of 84 deaths, there were few indications of incorrect labeling.     

Trends in self-poisoning in the elderly 1974–1983

Although the total suicide rate in England and Wales has risen between 1974 and 1983, the proportion due to self - poisoning has fallen, particularly in the younger age groups. While analgesics are now the commonest means of suicidal self - poisoning in both sexes and at all ages, barbiturates still account for a significant proportion of elderly suicides. Tricyclics and benzodiazepines are implicated in a relatively small proportion of suicides in old age. If removal of the means of suicide is an effective preventive strategy in the elderly, then more careful prescribing practices could lead to a lower suicide rate in this age group.     

Controlling firearms use in Australia: has the 1996 gun law reform produced the decrease in rates of suicide with this method?

BACKGROUND: Observed reductions in firearm suicides in Australia have been linked to the 1997 national firearms agreement (NFA) introduced following the 1996 Port Arthur massacre. The NFA placed strong access restrictions on firearms. AIMS: To assess the impact of legislative restrictions on the incidence of firearm suicide in Queensland and explore alternative or contributory factors behind observed declines. METHOD: The Queensland suicide register (QSR) provided detailed information on all male suicides in Queensland (1990-2004), with additional data for Australia (1968-2004) accessed from other official sources. Trends in suicide rates pre/post NFA, and in method selection, were assessed using negative binomial regressions. Changing method selection patterns were examined using a cohort analysis of 5 years of age classes for Australian males. RESULTS: The observed reduction in firearms suicides was initiated prior to the 1997 introduction of the NFA in Queensland and Australia, with a clear decline observed in Australian figures from 1988. No significant difference was found in the rate pre/post the introduction of the NFA in Queensland; however, a significant difference was found for Australian data, the quality of which is noticeably less satisfactory. A marked age-difference in method choice was observed through a cohort analysis demonstrating both time and age influences. Within sequential birth cohorts, rates of firearms suicides decreased in younger males but increased in hanging suicides; this trend was far less marked in older males. CONCLUSIONS: The implemented restrictions may not be responsible for the observed reductions in firearms suicide. Data suggest that a change in social and cultural attitudes could have contributed to the shift in method preference.     

Suicide rates in China from 2002 to 2011: an update

Purposes

The aims of this study were: (1) to present the time trend of suicide rate among people aged 15 or above in China over the period 2002–2011 and (2) to examine the current profile of completed suicides during 2009–2011.

Methods

Data on suicide rate in 2002–2011 were provided by the Chinese Ministry of Health (MOH). The trends of region-, gender-, and age-specific suicide rates were examined using Poisson regression models. The mean number of completed suicides for each cohort during 2009–2011 was calculated and a mean national suicide rate was estimated.

Findings

The overall suicide rate decreased significantly over the past decade, but rates in young males and rural older adults did not reduce and in fact increased among older adults in both urban and rural areas towards the end of the study period. For 2009–2011, 44 % of all suicides occurred among those aged 65 or above and 79 % among rural residents. The estimated mean national suicide rate was 9.8 per 100,000 and was slightly higher for males than females.

Conclusion

The benefits of economic growth, such as higher employment and more educational opportunities for the rural population in particular, may have contributed to the reduced suicide rate in China. However, the recent rapid changes in socioeconomic conditions could have increased stress levels and resulted in more suicides, especially among the elderly. Despite the significant reduction reported here, the latest figures suggest the declining trend is reversing. It will be important to continue monitoring the situation and to examine how urbanization and economic changes affect the well-being of 1.3 billion Chinese.     

Suicide in Austrian children and young adolescents aged 14 and younger

Introduction Research on suicide in childhood and early adolescence is sparse. We investigated suicide cases of children and young adolescents in terms of prevalence, gender differences, suicide methods and monthly distribution during a period of 32 years. Methods Registered suicides aged 14 or younger occurring between 1970 and 2001 (n = 275) in Austria were studied. Results The mean suicide rate for 10 to 14-year-olds was 1.4 per 100,000 with a male–female ratio of 3.1:1. The total child and young adolescent suicide rate and boys’ suicide rates decreased over the study period. However, there was no significant fluctuation in girls’ suicide rates. Hanging was the predominant suicide method in both genders. Use of this method decreased steadily over the study period, whereas the percentage of suicides by other methods, i.e., jumping and firearms suicides increased. Greater number of suicides in children and young adolescents was observed during the months of April/May and October/November. Conclusion Suicide rates of children and young adolescents in Austria are on the decrease, in accordance with a reported decrease in the general suicide rate in Austria.     

Are suicide rates in Sweden associated with changes in the prescribing of medicines?

A key issue in the debate on suicide prevention is the extent to which suicide rates are affected by the availability of means of committing suicide. The aim of this study was to analyse the changes in rates of suicides committed by poisoning in Sweden between 1969 and 1992, and to determine to what extent these were associated with changes in the prescribing of medicines. We compared suicide rates from 1969 to 1992 with trends in the sales of antidepressants, barbiturates, neuroleptics and analgesics during the same period. The incidence of suicide by poisoning decreased during the 1970s, especially in younger and middle-aged men. This was mainly due to a decrease in suicides by barbiturate poisoning, which closely followed a decrease in sales of barbiturates. Sales of analgesics and antidepressants increased during the study period, and so did the rates of suicide using these drugs. We conclude that the availability of medicines is an important factor influencing suicide rates, and that changes in the prescribing of medicines may influence suicide rates.     

Antidepressant drug consumption and public health indicators in Italy, 1955 to 2000

OBJECTIVE: This study investigated the impact of the increasing consumption of selective serotonin reuptake inhibitors (SSRIs) and newer anti-depressants on the following public health indicators: (1) suicide rates, (2) proportion of completed suicides by poisoning with solid or liquid substances, and (3) hospital admissions for depression and proportion of admissions for depression that were first admissions. METHOD: Data collected by IMS Health on antidepressants dispensed in Italy from 1983 to 2000 were obtained from the Italian Ministry of Health, while data on suicide deaths from 1955 to 2000 were obtained from the Italian National Institute of Statistics. RESULTS: In Italy from 1983 to 2000, the use of tricyclic antidepressants remained substantially stable, and the use of SSRIs and newer agents dramatically increased. In contrast, suicide rates for males decreased from 1955 to 1974 and subsequently increased, reaching a peak in 1985 and then declining. In females, suicide rates remained substantially stable until 1978. A subsequent increase occurred up to 1985, followed by a steady decline. Suicide by poisoning using solids or liquids dropped by nearly 50% from 1986 to 2000. Admissions to the hospital for depression showed an erratic pattern; however, no decline was observed. No change was observed in the rate of first admissions for depression. CONCLUSION: Despite a reduction in suicides by poisoning using solids or liquids, the analysis of long-term trends in suicide did not suggest that increases in antidepressant prescribing lie behind recent reductions in population suicides. Furthermore, in Italy, newer antidepressants had no impact on the total number of admissions for depression or on the proportion of all admissions that were first admissions.     

A study of suicides of older people in Sydney

BACKGROUND: Reports based on studies of coroner's files show that suicides in old age are commonly related to depression, but that in a majority of cases disability or ill-health is also a major factor. The aim of this study was to try to understand more clearly the precipitant causes of suicide in an older population. METHOD: An Australian metropolitan coroner's office provided data concerning suicides in 1994-1998 of persons aged over 65 years. RESULTS: Of 210 elderly people who killed themselves, 160 (76%) were clearly depressed, including a majority of the 24% deemed to have understandable reasons for suicide. Physical ill-health or disability was the major factor leading to suicide in 34% and appeared to contribute to suicidal ideation in another 24% of those who died; they had usually not been seen by psychiatrists. CONCLUSION: Because depression is often treatable, even when associated with depressing circumstances, there is potential for further reduction of old age suicide rates by recognising and appropriately responding to symptoms of depression and distress.     

Suizid im psychiatrischen Krankenhaus

Suicide prevention is a core responsibility of psychiatry and psychotherapy. Periods of change in psychiatric inpatient treatment concepts are usually also accompanied by an increase in psychopathological behavior and with increased suicide rates in psychiatric hospitals, as seen in the 1970s and 1980s in Germany. That this represented a real increase of inpatient suicides during those years was confirmed and subsequently the number and rate of inpatient suicides has decreased from approximately 280 out of 100,000 admissions of patients in 1980 to approximately 50 in 2014. Death can also occur in psychiatric hospitals and an absolute prevention is not possible even under optimal conditions of therapy and nursing, communication and security. The suicide rate has clearly decreased over the last two decades in relation to admissions. The group of young male schizophrenic patients newly identified as having a high clinical suicide risk has decreased among the suicide victims whereas the percentage of severely depressed patients with delusions has increased. This reduction could be associated with the comprehensive improvements in educational and training programs in the field of suicide and suicide prevention, objectification of coping methods, development of diagnostic and therapeutic strategies, improvements in therapy and relationship possibilities and a general reduction in the number of suicides in Germany.     

The sex distribution of suicides by age in nations of the world

Summary The ratio of the male suicide rate to the female suicide rate for each age group in 31 nations of the world was found to be associated with the wealth of the nations. The male/female suicide rate ratio was lower in wealthier nations for older adults and higher in wealthier nations for youths. The male-female suicide rate ratio was associated over the nations among the younger age groups and also among the older age groups. These results suggest that the sex ratio may be differently determined in youths and in older adults.     

Suicide in Hong Kong

Coroners' statistics indicated there were 684 suicides for the whole of Hong Kong in 1981. This gave a crude suicide rate of 18.1 per 100,000 population aged 15 years and over and constituted 2.7% of all deaths reported in that year. Only a few data were recorded in all coroners' files but additional data were obtained from police records on 168 of these suicides. The age and sex distribution among the suicides as well as the effect of marital and employment status on suicide rates were found to be similar to western countries. Jumping from a height was the most common method of suicide (47.2%) followed by hanging (30.8%). Psychiatric illness and chronic physical disability were two most important precipitating causes of suicide (39.8% and 35.7% respectively). Twenty per cent had a history of previous attempts with one-third occurring within six months of their completed suicide. Over 40% had communicated their suicide intention to others, while 19% left a note. 'Psychiatric' cases as a group had special features: there were more in the younger age groups, more with records of previous suicide attempts and more chose readily available methods.
