Evidence-based prevention strategies of suicide behavior in the world: implications for Slovenia

In this review we consider how Slovenia could consider tackling its high rate of suicide (overall 29 per 100,000, 46 in males, 13 in females). First, we consider the evidence for risk factors that may contribute to Slovenia's high rate of suicide. Second, we describe the interventions to try to reduce the impact of these factors and the evidence for such interventions. We categorize interventions in terms of their operation at either the population level or that of high-risk groups. However, it should be borne in mind that settings often assumed to provide access to population groups, such as general practice and schools, do not reach some people who are likely to be at high risk; for example those who have dropped out of school or who have been excluded from a GP's list. We focus particularly on those for high-risk groups, as a number of East-European countries with high suicide rates such as Slovenia, Hungary, and the Baltic republics are currently considering a shift toward more community-based mental health services. The provision of community mental health services in Slovenia would provide an opportunity to study their impact on the suicide rate. However, we conclude that their development should be accompanied by other initiatives operating at population levels. This multilevel approach acknowledges the complexity of the etiology of suicide, the impossibility of reaching all those at risk through services and the lack of strong evidence for any one intervention.     

Adolescent self-poisoning: a cohort study of subsequent suicide and premature deaths

Previous self-harm has been identified as a risk factor for subsequent suicide by adolescents. The objective of the study was to identify further risk factors for subsequent premature death and suicide in a population of adolescents presenting with self-poisoning. A longitudinal cohort design using data-linkage of consecutive adolescent patients presenting to the Hunter Area Toxicology Service, a regional toxicology service for Newcastle, Australia, with the National Death Index of the Australian Institute of Health and Welfare was used. A total of 441 adolescents aged 10 to 19 years presented with self-poisoning over 5 years from January 1991 to December 1995, with follow-up to March 2001. There were 14 deaths total, eight of which were likely suicides. There was a 22-fold increase in suicide rate for males and a 14-fold increase for females compared with age-normalized population rates. Adjusted hazard ratios (95% CI) forpremature death were male gender 3.77 (1.11-12.78), nonaffective psychotic disorders 16.3 (3.83-69.34) and the mental illnesses of childhood 6.12 (1.68-22.23). There was a similar pattern for suicide: Male gender, nonaffective psychotic disorders, and the mental illnesses of childhood confer greater risk for subsequent suicide or premature death in this population.     

Body mass and suicide risk

Body mass has been neglected as a possible predictor of suicidal behavior. The present investigation explores the association between body mass index and completed suicide. Data are from the National Mortality Followback Survey and refer to 373 suicides, and 518 deaths from motor vehicle accidents as controls. The results of a logistic regression analysis indicated that, for females, the greater the BMI the greater the suicide risk. However, this relationship did not hold up under controls for race and other covariates of BMI. For males, the BMI was not significantly related to suicide risk either at the bivariate or multivariate levels of analysis. The best predictors of suicide were living alone for females, and alcohol abuse for males.     

Familial study of suicidal behavior among adolescents in Slovenia

The number of adolescents who attempt or complete suicide is increasing. Risk factors range from mental disorders, to problems at school, family problems, or difficulties in establishing relationships. A further important, and too often underestimated, risk factor for adolescent suicide is the presence of suicidal behavior in the adolescent's family. We investigated 184 high school adolescents in a region in Slovenia with a high suicide rate (30/100,000/year). They were questioned by means of an anonymous questionnaire about the presence of suicidal behavior in their relatives and about the presence of suicidal thoughts, plans, and acts in themselves. The results revealed that 13% of the adolescents studied had a relative who had attempted suicide and a further 9% of the adolescents had lost a relative due to suicide. About half of all females and almost a third of males had had suicidal thoughts (differences between sexes were statistically significant: chi2 = 6.13; p < .01). Attempted suicide among relatives was positively correlated with the presence of suicidal plans among adolescents (phi = 0.15; p < .05). This correlation proved to be even stronger and statistically more significant in men when we split the sample by gender. All variables (suicidal thoughts, suicidal plans, and suicide attempts) in the adolescent males positively correlated with attempted suicide among their relatives ((phi = 0.28, p < .01; phi) = 0.26, p < .05; phi = 0.34, p < .01; respectively). Our results speak in favor of a higher risk of suicidal behavior among adolescents with suicidal behavior in their families.     

Long- and short-term risk factors in the prediction of inpatient suicide: review of the literature

The prediction of suicide remains a major challenge for health care professionals in inpatient settings. A clearer identification of factors specific to inpatient suicide is required to improve both practice and research within this area. This paper provides an overview of the inpatient suicide literature to date focusing on two particularly salient themes: Long term and short term prediction of suicide. Since the concept of short-term suicide risk dominates clinical practice, issues in relation to dynamic risk factors are emphasized.     

A pilot study of the suicide victim's last contact with a health professional

Suicide victims frequently have contact with health care professionals in the months before death. The primary aims of this pilot psychological autopsy study were to determine the feasibility of undertaking a full study and to describe the characteristics of the last health care professional contacts with suicide victims aged > 34 years. We interviewed the informants of 52 suicides. Interviews were obtained from 37 health care professionals who had contact with 28 of the suicides during the 3 months before death. The primary reasons for the last contact with the health care professional were mental health (62%), physical health (22%), and social (14%). 87% of health care professional contacts occurred within 1 month of death. Symptoms of depression were noted in 49% of health care professional contacts. Consensus psychological autopsy diagnoses of depression were made in 64% of suicide victims. Overall suicide risk was assessed by 38% of health care professionals during their last contact. This was more likely to occur when the deceased presented as depressed, was aged < 60 years or seen by a psychiatrist. None was assessed to be suicidal. The family informants regarded nine of the suicide victims to have been suicidal before death but informed a health care professional in only one third of the cases. Critical information that might have altered the management is not often accessed from family members.     

Coping with youth suicide and overdose: one community's efforts to investigate, intervene, and prevent suicide contagion

From 2000-2005, Somerville, MA, experienced a number of youth overdoses and suicides. The community response followed CDC recommendations for contagion containment. A community coalition, Somerville Cares About Prevention, became a pivotal convener of community partners and a local research organization, the Institute for Community Health, provided needed expertise in surveillance and analysis. Mayoral leadership provided the impetus for action while community activists connected those at risk with mental health resources. Using a variety of data sources (including death certificates, youth risk surveys, 911 call data, and hospital discharges) overdose and suicide activity were monitored. Rates of suicide and overdose for 10-24-year-olds were higher than in previous years. Using case investigation methods, the majority of suicide victims were found to be linked through common peer groups and substance abuse. Subsequent community action steps included: a community-based trauma response team, improved media relationships, focus groups for suicide survivors, and prevention trainings to community stakeholders. Youth suicide and overdose activity subsided in May of 2005. The community partnerships were critical elements for developing a response to this public health crisis. This collaborative approach to suicide contagion used existing resources and provides important lessons learned for other communities facing similar circumstances.     

Socioeconomic change and suicide: a time-series study from the Republic of Ireland

This ecological study examined the association between seven socioeconomic indicators (GDP, unemployment rate, female labor force participation rate, alcohol expenditure, marriage rate, percentage of births outside of marriage, and indictable crime rate) and total, male, and female rates of suicide and suicide plus undetermined death in Ireland during the period 1968-2000. Analysis of the data expressed as absolute values showed highly significant associations between the socioeconomic indicators and the total, male, and female suicide rates. However, these associations were explained by the strongly trended data. The trended nature of the data was removed by using year-to-year differences. Analysis of the first-differenced data showed that none of the socioeconomic indicators was associated with the total, male, or female suicide rates with the exception of indictable crime, which had a significant independent effect on the female suicide rate (coefficient = 2.0, p < .01) but not on suicide plus undetermined death. This study highlights the need to use econometric methods in time-trend analyses, the lack of age-sex specific exposure data in this area, and the challenge of understanding trends in suicide in their socioeconomic context.     

Suicidal Ideation Among Women Court-Referred to Batterer Intervention Programs

Identifying the prevalence and correlates of suicidal ideation in women mandated to batterer intervention programs is necessary to prevent suicide in this greatly understudied population. This study used cross-sectional, self-report survey methodology to identify the prevalence and correlates of suicidal ideation among 79 women attending batterer intervention programs. Of the sample, 33% reported experiencing suicidal ideation during the two weeks prior to entering the program. Multiple linear regression analysis indicated that (while controlling for number of batterer intervention sessions attended) symptoms of depression and borderline personality disorder, but not symptoms of antisocial personality disorder, were associated with suicidal ideation.     

Male and Female Suicide Bombers: Different Sexes,Different Reasons?

This article analyzes the motivations and recruitment of female suicide terrorists. Biographical accounts of 30 female and 30 male suicide terrorists were coded for method of recruitment, motivation for attack, and outcome of attack. A log-linear analysis found that female suicide terrorists were motivated more by Personal events, whereas males were motivated more by Religious/nationalistic factors. Females were equally likely as males to be recruited through peer influence, exploitation, or self promotion, whereas males were more likely to be recruited as a result of religious persuasion. The results highlight the need for continued research into female terrorism.     

Suicide on the Indian subcontinent

The Indian subcontinent comprises eight countries (India, Pakistan, Bangladesh, Nepal, Sri Lanka, Afghanistan, Bhutan, and the Maldives) and a collective population of more than 1.3 billion people. 10% of the world's suicides (more than 100,000 people) take place in just three of these countries, viz. India, Sri Lanka, and Pakistan. There is very little information on suicides from the other four countries. Some differences from suicides in Western countries include the high use of organophosphate insecticides, larger numbers of married women, fewer elderly subjects, and interpersonal relationship problems and life events as important causative factors. There is need for more and better information regarding suicide in the countries of the Indian subcontinent. In particular, studies must address culture-specific risk factors associated with suicide in these countries. The prevention of this important public health problem in an area of the world with myriad socio-economic problems, meager resources, and stigmatization of mental illness poses a formidable challenge to mental health professionals, policy makers, and governments of these countries.     

Networking to support suicide survivors

This paper is the first report on a national program for increasing bereavement support for suicide survivors in the Flemish region in Belgium. A Working Group consisting of representatives of a wide variety of mental health institutions, social programs, and suicide survivor groups in the area determined that a program developing networks between the services seems to hold the greatest promise for both an increase in the number of services available and an improvement in the quality of services offered.     

Suicide in Bahrain in the last decade

A combination of social, legal, and religious factors make reporting of suicide difficult in Bahrain, an Islamic country. Limited available data indicates a very low incidence rate of 3 per 100,000. The objective of the present study was to describe the pattern of suicide in Bahrain during a 10-year period. The registered suicide cases (N = 304) at the Ministry of Interior for the 10-year period from 1995 to 2004 were reviewed and analyzed. The mean suicide rate was 0.6 per 100,000 for the Bahraini nationals and 12.6 per 100,000 for the non-Bahrainis with and 17.7 per 100,000 for the Indian migrants. Men were six times more likely than women to commit suicide. The majority of the subjects were under 35 years of age with financial domestic problems being the most common reason reported in the record and hanging the mostly commonly used mode of suicide (92.8%). The suicide rate for the Bahraini population remains low compared to other countries. The higher rate of suicide among Indians merits further investigation. Moreover, more research is needed on the epidemiology of suicide risk factors in ethnic groups for further prevention and intervention.     

Child and adolescent suicide deaths in New Mexico, 1990-1994

The suicide death rate in New Mexico is consistently higher than the national rate. Among adolescents, suicide is the third leading cause of death nationally, but in New Mexico it is the second leading cause of death. This study describes the pattern of adolescent suicide deaths in New Mexico. We conducted a retrospective review of all medical examiner autopsies for adolescent suicides (ages 20 years and younger) in New Mexico from 1990-1994. Records were reviewed for demographics and possible contributing factors such as depression, previous attempts, and alcohol and drug use. We identified 184 suicide deaths among children and adolescents ages 9-20 years for an overall rate of 12.9 per 100,000. Our rates for ages 5-9 years (0.2), 10-14 years (3.8), and 15-19 years (22.3) are over twice the U. S. rates. Suicide deaths resulted primarily from firearms (67%), hanging (16%), poisoning (6%), inhalation (4%), and other methods (7%). Method varied by ethnicity (p = .01) and gender (p = .03); males and non-Hispanic Whites were overrepresented among firearm deaths. Firearm ownership was known in 60 (48%) of the firearm deaths. Of these, 53% of the firearms belonged to a family member, 25% to the decedent, and 22% to a friend. Over one-third of decedents (41%) experienced mental disorders, primarily depressed mood and clinical depression. Previous suicide attempts were noted for 15% of the decedents. Some 50% of the decedents had alcohol or drugs present at the time of death; among American Indians/Alaska Natives, 74% had drugs or alcohol present (p = .003). Targeted interventions are needed to reduce adolescent suicide in New Mexico. We suggest raising awareness about acute and chronic contributing factors to suicide; training physicians to look for behavioral manifestations of depression; and involving physicians, teachers, and youth activity leaders in efforts to limit firearm accessibility, such as advising parents to remove firearms from their households.     

The most common method of suicide in Tehran 2000-2004: implications for prevention

The likelihood of completing suicide depends to some extent on knowledge of effective means and also on the availability and/or acceptability of such methods. Since studying suicide methods may have an implication for prevention, the focus of this study was on the most favored method of suicide in Tehran, Iran. The study uses confirmed suicide data provided by the Beheshet Zahra Organization (BZO), which gathers all mortality data within Tehran and enters them into a computerized database, from which the relevant information for all the recorded suicide cases during the year 2000 to 2004 were obtained and analyzed. There were 703 cases of suicide (632 males and 71 females) in the BZO database, with a sex ratio of 8.9. The mean (standard deviation) of age at suicide for those who chose hanging and for those who have chosen other methods of suicide were 33.93 (14.2) and 34.60 (13.4) years, respectively. Hanging was the method favored by 572 (85.9%) of cases. Use of hanging was higher in females (61, 85.9%) than in males (511, 80.9%), and higher among the married (304, 53.6%) than among singles (268, 46.4%). The high proportion of persons using hanging as a method of suicide in Tehran may reflect the fact that this method is more acceptable and/or easily available and/or less likely to be misclassified as accidental or undetermined death. The prevention of such suicides is extremely difficult in the general population. Therefore, it is suggested that, to prevent suicide by hangings, the authorities should focus on the causal factors of suicide rather than on the acceptability and/or the availability of this method.     

Years of life lost from suicide in China, 1990-2000

Suicide is an important public health problem in China: It is the fifth leading cause of death in China, and suicide in China accounts for over 30% of the world's overall suicide deaths. The substantial burden due to suicide has not been well recognized. This study aims to provide an estimate of the socioeconomic burden of the suicide problem in China in terms of years of life lost (YLL) and to discuss its implications. Suicide rates and the related YLL by age, gender, and region (urban/rural) from 1990 to 2000 were estimated using the most recent data from the Ministry of Health of China. The suicide rate in rural China was three times higher than that in urban areas. Suicide completers in rural areas shared 90% of total YLL. Rural women aged 25-39 years contributed the largest share of YLL. Our results show that some population subgroups contributed a disproportionate share to the disease burden of suicide. National strategies for suicide prevention should include targeted programs in catering the need of these specified subgroups in China.     

Can a theory of suicide predict all "suicides" in the elderly?

Older adults consistently have the highest rates of suicide in most societies. Despite the paucity of studies until recently, research has shown that suicides in later life are best understood as a multidimensional event. An especially neglected area of research is the psychological/psychiatric study of personality factors in the event. This paper outlines one comprehensive model of suicide and then raises the question: Is such a psychiatric/psychological theory applicable to all suicides in the elderly? To address the question, I discuss the case of Sigmund Freud; raise the topic of suicide and/or dignified death in the terminally ill; and examine suicide notes of the both terminally ill and nonterminally ill elderly. I conclude that, indeed, greater study and theory building are needed into the "suicides" of the elderly, including those who are terminally ill.     

Personality and repeated suicide attempts in dependent adolescents and young adults

This study compared personality characteristics of subjects with dependence disorders who had previously made a suicide attempt. The population, recruited in France, Belgium, and Switzerland, was composed of 570 subjects (225 females, 345 males, mean age = 27.3, SD = 8.5). The subjects' psychological dimensions were investigated by means of several self-report questionnaires including: BDI-13 (Beck), Sensation-Seeking Scale (Zuckerman), Toronto Alexithymia Scale (Taylor), Interpersonal Dependency Inventory (Hirschfeld), MMPI-2, and some additional scales. For most dimensions, repeat attempters, both past and recent, but more specifically the recent repeaters, had a more severe psychological profile compared to the other suicide attempters.     

Risk of suicide ideation associated with problem-solving ability and attitudes toward suicidal behavior in university students

The present paper investigates the risk of lifetime suicide ideation associated with problem-solving ability and attitudes toward suicidal behavior in a sample of 328 university students (41% male, 59% female). The response rate was 77% based on the total number of students registered for the relevant courses. A series of questions assessed lifetime suicide ideation, while problem solving and attitudes toward suicide were measured using the Self-Rating Problem Solving scale and four subscales of the Suicide Opinion Questionnaire, respectively (McLeavey, 1986; Domino et al., 1989). Almost one-third of the students surveyed had lifetime suicide ideation. Both genders were similar in terms of their suicide ideation history, problem solving, and attitudes toward suicidal behavior with the exception that male students were more in agreement with the attitude that suicidal behavior lacks real intent. Compared with 2% of nonideators and ideators, one in four planners reported that they would more than likely attempt suicide at some point in their life. Greater agreement with the attitude that suicidal behavior is normal was associated with significantly increased risk of being an ideator, as was poor problem solving and less agreement with the attitude that suicidal behavior is associated with mental illness.     

Suicide in developing countries (2): risk factors

The majority of studies on risk factors for suicide have been conducted in developed countries, and less work has been done to systematically profile risk factors in developing countries. The current paper presents a selective review of sociodemographic, clinical, and environmental/situational risk factors in developing countries. Taken together, the evidence suggests that the profiles of risk factors in developing countries demonstrate some differences from those in developed countries. In some developing countries, at least, being female, living in a rural area, and holding religious beliefs that sanction suicide may be of more relevance to suicide risk than these factors are in developed countries. Conversely, being single or having a history of mental illness may be of less relevance. Risk factors that appear to be universal include youth or old age, low socioeconomic standing, substance use, and previous suicide attempts. Recent stressful life events play a role in both developing and developed countries, although their nature may differ (e.g., social change may have more of an influence in the former). Likewise, access to means heightens risk in both, but the specific means may vary (e.g., access to pesticides is of more relevance in developing countries). These findings have clear implications for suicide prevention, suggesting that preventive efforts that have shown promise in developed countries may need to be tailored differently to address the risk factor profile of developing countries.
