Why has suicide increased in young males?

Psychological autopsy: Overview of Indian evidence, best practice elements, and a semi-structured interview guide

BACKGROUND

No review has been attempted, so far, on Indian psychological autopsy (PA) literature. There is also a dearth of interview guides which is at the heart of a PA procedure.

MATERIALS AND METHODS

Electronic searches of MEDLINE through PubMed, PsycINFO, and Google scholar databases were carried out from inception till February 2020 to identify relevant English language peer-reviewed articles from India, as well as global literature that provided information on best practice elements in PA. Abstracts generated were systematically screened for eligibility. Relevant data were extracted using a predesigned structured proforma, and a semi-structured interview guide was developed.

RESULTS

A total of 18 original articles, one case report, and three reviews/expert opinion articles which tried to give a description of PA procedure were found from India. Most Indian studies are of suicide PA (SPA), done to assess risk factors associated with suicide. There was a wide variation in reported rates of psychiatric morbidity among suicide decedents, while the other major risk factor for suicide in the Indian setting was stressful life events. An optimal approach to PA involves systematically collecting information from key informants and other sources using a narrative interviewing method, supplemented with psychological measures, and is probably best carried out within 1-6 months after the death.

CONCLUSION

There have been limited attempts to standardize PA. Most Indian studies use SPA. We propose a semi-structured PA interview guide, suitable for both research and investigational purposes.

Suicidal ideation, behavior, and mortality in male and female US veterans with severe mental illness

BACKGROUND

We compared male and female American veterans with schizophrenia or bipolar disorder regarding clinical characteristics associated with lifetime suicidal ideation and behavior. Subsequent mortality, including death by suicide, was also assessed.

METHODS

Data from questionnaires and face-to-face evaluations were collected during 2011-2014 from 8,049 male and 1,290 female veterans with schizophrenia or bipolar disorder. In addition to comparing male-female characteristics, Cox regression models-adjusted for demographic information, medical-psychiatric comorbidities, and self-reported suicidal ideation and behavior-were used to examine gender differences in associations of putative risk factors with suicide-specific and all-cause mortality during up to six years of follow-up.

RESULTS

Women overall were younger, more likely to report a history of suicidal behavior, less likely to be substance abusers, and had lower overall mortality during follow-up. Among women only, psychiatric comorbidity was paradoxically associated with lower all-cause mortality (hazard ratio [HR]=0.53, 95% CI, 0.29-0.96, p = 0.037 for 1 disorder vs. none; HR=0.44, 95% CI, 0.25-0.77, p = 0.004 for ≥2 disorders vs. none). Suicide-specific mortality involved relatively few events, but crude rates were an order of magnitude higher than in the U.S. general and overall veteran populations.

LIMITATIONS

Incomplete cause-of-death information and low statistical power for male-female comparisons regarding mortality.

CONCLUSIONS

Female veterans with SMI differed from females in the general population by having a higher risk of suicide attempts. They also had more lifetime suicide attempts than male veterans with same diagnoses. These differences should inform public policy and clinical planning.

Smartphone Applications for Mindfulness Interventions with Suicidality in Asian Older Adults: A Literature Review

Elderly suicide is a rising concern. Despite the advent of mobile technology, there remained a gap in the evidence base as to whether smartphone applications could be used for mindfulness intervention for suicidality in Asian older adults. This paper aimed to review recent research relevant to smartphone applications that could be used in providing mindfulness interventions for suicidality to Asian older adults. The inclusion criteria for this review were papers published in peer-reviewed journals from 2008 to 2018 with the usage of specific search terms, namely, ‘smartphone application’, ‘mobile application’, and ‘mindfulness’, assessed against the inclusion criteria and screened by an experienced Asian clinician to be of clinical utility for mindfulness intervention for suicidality with Asian older adults. Initial search on databases yielded 236 results. A total of 35 full text papers that fit the inclusion criteria were assessed for eligibility and 10 papers were included in the current review. This review highlighted the paucity of rigorous empirically validated research into effective smartphone applications that can be used for mindfulness interventions for suicidality with Asian older adults.

Influencing the Conversation About Masculinity and Suicide: Evaluation of the Man Up Multimedia Campaign Using Twitter Data

BACKGROUND

It has been suggested that some dominant aspects of traditional masculinity are contributing to the high suicide rates among Australian men. We developed a three-episode documentary called Man Up, which explores the complex relationship between masculinity and suicide and encourages men to question socially imposed rules about what it means to be a man and asks them to open up, express difficult emotions, and seek help if and when needed. We ran a three-phase social media campaign alongside the documentary using 5 channels (Twitter, Facebook, Instagram, YouTube, and Tumblr).

OBJECTIVE

This study aimed to examine the extent to which the Man Up Twitter campaign influenced the social media conversation about masculinity and suicide.

METHODS

We used Twitter insights data to assess the reach of and engagement with the campaign (using metrics on followers, likes, retweets, and impressions) and to determine the highest and lowest performing tweets in the campaign (using an aggregated performance measure of reactions). We used original content tweets to determine whether the campaign increased the volume of relevant Twitter conversations (aggregating the number of tweets for selected campaign hashtags over time), and we used a subset of these data to gain insight into the main content themes with respect to audience engagement.

RESULTS

The campaign generated a strong following that was engaged with the content of the campaign; over its whole duration, the campaign earned approximately 5000 likes and 2500 retweets and gained around 1,022,000 impressions. The highest performing tweets posted by the host included video footage and occurred during the most active period of the campaign (around the screening of the documentary). The volume of conversations in relation to commonly used hashtags (#MANUP, #ABCMANUP, #LISTENUP, and #SPEAKUP) grew in direct relation to the campaign activities, achieving strongest growth during the 3 weeks when the documentary was aired. Strongest engagement was found with content related to help-seeking, masculinity, and expressing emotions. A number of followers tweeted personal stories that revealed overwhelmingly positive perceptions of the content of the documentary and strongly endorsed its messages.

CONCLUSIONS

The Man Up Twitter campaign triggered conversations about masculinity and suicide that otherwise may not have happened. For some, this may have been game-changing in terms of shifting attitudes toward expressing emotions and reaching out to others for help. The campaign was particularly effective in disseminating information and promoting conversations in real time, an advantage that it had over more traditional health promotion campaigns. This sort of approach could well be adapted to other areas of mental (and physical) health promotion campaigns to increase their reach and effectiveness.

What predicts medical lethality of suicide attempts in Asian youths?

This study explores youth suicide attempts in Singapore using multiple databases of comprehensive archival records. Three years of medical records related to suicide attempters (N=666) who were admitted to the emergency department of a large teaching hospital in Singapore were subjected to retrospective analysis. Compared to other age groups, a peak in suicide attempts (n=207) was observed in youths aged between 15 and 24 years old (76.3% females; 23.7% males, mean age=19.30, SD=2.89). The model using recognized risk and protective factors was significant in predicting medical lethality, and correctly classified 62.8% of high lethality cases. Only resolution of precipitant made a unique statistical significant contribution. Analysis was separately conducted for males and females. Implications of the findings are discussed.

Masculinity and suicidal thinking

PURPOSE

Males feature prominently in suicide statistics, but relatively little work has been done to date to explore whether endorsement of dominant masculinity norms heightens the risk of or is protective against suicidal thinking. This paper aimed to further knowledge in this area.

METHODS

We used baseline data from 13,884 men (aged 18-55) in the Australian Longitudinal Study on Male Health (Ten to Men) cohort. These men filled in self-complete questionnaires in 2013/14 which covered a range of topics, including conformity to dominant masculinity norms and suicidal thinking. We conducted logistic regression analyses to estimate the strength of association between these two variables.

RESULTS

After controlling for other key predictors of suicidal thinking, one characteristic of dominant masculinity-self-reliance-stood out as a risk factor for suicidal thinking (AOR 1.33; 95% CI 1.25-1.42).

CONCLUSIONS

It suggests that one particular element of dominant masculinity-being self-reliant-may place men at increased risk of suicidal thinking. This finding resonates with current theories of how suicidal thinking develops and leads to action. It also has implications for the full gamut of suicide prevention approaches that target males in clinical settings and in the general population, and for our broader society. Further work is needed, however, to confirm the direction of the relationship between self-reliance and suicidality, and to unpack the means through which self-reliance may exert an influence.

Adolescents' self-reported suicide attempts, self-harm thoughts and their correlates across 17 European countries

BACKGROUND

  Suicide is a leading cause of death among adolescents in Europe. Self-harm thoughts and behaviours are documented precursors of completed suicide. It is therefore of great importance to investigate the prevalence of suicide thoughts and attempts and their correlates, with the aim of preventing this major life-threatening public health problem. This study provides cross-national European data on self-reported suicidal thoughts and attempts among adolescents.

METHODS

  Data were obtained from 45,806 high school students aged 15-16 years from 17 countries that participated in the European School Survey Project on Alcohol and Other Drugs (ESPAD) 2007 school survey. The standardised methods of the ESPAD survey ensure comparability across countries. Students completed an anonymous questionnaire in their classrooms. The prevalences of suicidal thoughts and attempts are reported as well as their sociodemographic and psychosocial correlates identified in logistic regression.

RESULTS

  The median prevalence of any lifetime self-reported suicide attempt was 10.5% across the participating countries (range 4.1%-23.5%). The median of frequent self-harm thoughts (at least five times) was 7.4% (range 2.1%-15.3%). Suicidal behaviour and thoughts had significant associations with gender, substance use, family integrity and socioeconomic status. Countries with higher prevalence of substance use tended to have a weaker association between substance use and self-reported suicide attempts.

CONCLUSION

  Although self-reported self-harm thoughts and suicide attempts vary in prevalence within Europe, there are common correlates across countries. These have an important impact on understanding the phenomenon of suicide among young people and in guiding prevention.

An ecological study of community-level correlates of suicide mortality rates in the Flemish region of Belgium, 1996-2005

An ecological study of age-standardized suicide rates in Belgian communities (1996-2005) was conducted using spatial regression techniques. Community characteristics were significantly related to suicide rates. There was mixed support for the social integration perspective: single person households were associated with higher suicide rates, while religious participation was unrelated and both immigration and the presence of non-European inhabitants had a negative impact. Deprivation had a positive relation with suicide. Population density had a negative influence on suicide rates. Areas with older populations had higher suicide risks than expected. A spatial contagion effect of neighboring communities was present for men. In the conclusion, hypotheses are presented on why an aging population could be associated with higher suicide rates in the community.

Explaining gender differences in non-fatal suicidal behaviour among adolescents: a population-based study

BACKGROUND

While suicide is the second leading cause of death among young people in most industrial countries, non-fatal suicidal behaviour is also a very important public health concern among adolescents. The aim of this study was to investigate gender differences in prevalence and emotional and behavioural correlates of suicidal behaviour in a representative school-based sample of adolescents.

METHODS

A cross-sectional design was used to assess suicidal behaviour and various areas of emotional and behavioural problems by using a self-report booklet including the Youth Self-Report. One hundred sixteen schools in a region of Southern Germany agreed to participate. A representative sample of 5,512 ninth-grade students was studied. Mean age was 14.8 years (SD 0.73); 49.8% were female.

RESULTS

Serious suicidal thoughts were reported by 19.8% of the female students and 10.8% of the females had ever attempted suicide. In the male group, 9.3% had a history of suicidal thoughts and 4.9% had previously attempted suicide. Internalizing emotional and behavioural problems were shown to be higher in the female group (difference of the group means 4.41) while externalizing emotional and behavioural problems slightly predominated in male students (difference of the group means -0.65). However, the total rate of emotional and behavioural problems was significantly higher in the adolescent female group (difference of the group means 4.98). Using logistic regression models with suicidal thoughts or attempted suicide as dependent variables, the pseudo-R2 of gender alone was only 2.7% or 2.3%, while it was 30% or 23.2% for emotional and behavioural problems measured by the YSR syndrome scales. By adding gender to the emotional and behavioural problems only an additional 0.3% of information could be explained.

CONCLUSIONS

The findings suggest that gender differences in non-fatal suicidal behaviour among adolescents can to a large extent be explained by the gender differences in emotional and behavioural problems during this age.

An empirical test of a mediation model of the impact of the traditional male gender role on suicidal behavior in men

BACKGROUND

Men die by suicide three to four times more often than women in Western countries. The adverse impact of the traditional male gender role as well as men's reluctance to seek help are possible explanations of this gender gap, but these hypotheses have not been well documented empirically.

METHODS

This study compares two groups of men who experienced comparable severely stressful life events during the preceding 12 months: 40 men admitted to hospital emergency following suicide attempts, and 40 men with no history of suicide attempts. Structured interviews were conducted to measure adherence to the traditional male gender role, help seeking behaviour, social support, suicide acceptability and mental health.

RESULTS

ANOVAS indicated that attempters are more likely to adhere to the traditional masculine gender role and regression analysis revealed that this relationship persists even when the presence of mental disorders is statistically controlled. Sequential regression analysis support the mediation model and show that the effects of the traditional male gender role on suicidal behavior are mediated through protective and risk factors for suicide, namely mental state, help seeking and social support.

CONCLUSIONS

The traditional male gender role appears to increase the risk of suicidal behavior in men by undermining their mental state and by inhibiting the protective factors of help seeking and social support. This study underscores the importance of encouraging men to seek help.

Sexual differences in the completed suicides in Turkey

The aim of this study was to determine whether there is a difference between men and women in terms of suicide age, suicide method and suicide reason in Turkey. This study recruited 17,327 cases that had committed suicide between 1990 and 2000. Of all the cases who committed suicide during a period of 11 years, 61.1% were men, 38.9% women. The highest suicide score fell into the age group 15-24 (P<0.001). The most frequently used methods for suicide were self-hanging (48.2%) and use of firearms (19.2%) (P<0.001). The proportion of those committing suicide taking chemicals (drugs, etc.) was higher in women than in men (P<0.001). The most frequently seen reasons for suicide were illness and (33.8%) unsatisfactory relationships (33.0%) (P<0.001, each one). Women committed suicide much more because of unsatisfactory relationships, whereas for men it was due to illness (20.8% and 14.6%, respectively). There were significant differences between men and women in terms of suicide age, suicide method and suicide reason in Turkey. When evaluating suicide cases it is essential that the differences between sexes be taken into consideration.

THE ASSOCIATION BETWEEN ALCOHOL MISUSE AND SUICIDAL BEHAVIOUR

AIMS

Despite recent small reductions in overall suicide rates, rates among those aged 25-44 have remained high. The aim of this paper was to examine the evidence for a link between alcohol misuse/consumption and suicidal behaviour, explore the reasons for this association, and consider the implications for reducing rates of suicidal behaviour.

METHODS

A medline search was performed to find relevant research evidence.

RESULTS

There is evidence to suggest alcohol misuse predisposes to suicidal behaviour through its depressogenic effects and promotion of adverse life events, and both behaviours may share a common genetic predisposition. Acute alcohol use can also precipitate suicidal behaviours through induction of negative affect and impairment of problem-solving skills, as well as aggravation of impulsive personality traits, possibly through effects on serotonergic neurotransmission.

CONCLUSIONS

Effective interventions for problem drinking may help reduce suicide rates. At a public health level, reducing overall alcohol consumption may be beneficial, and the measures shown to be most effective in this regard are those that aim to restrict availability of alcohol.

Sex, gender role orientation, gender role attitudes and suicidal thoughts in three generations. A general population study

BACKGROUND

Suicide and other suicidal behaviours are markedly (though differently) patterned by gender. The increase in young male suicide rates in many countries has heightened interest in whether suicidal behaviours and ideation (thoughts) are related to masculinity. Relatively little research has explored the relationship between gender role attitudes and orientation and suicidal behaviours and ideation. Most research in this area has been conducted with young people.

OBJECTIVE

We investigated whether gender role orientation (masculinity and femininity scores) and gender role attitudes were related to the reporting of serious suicidal thoughts in three generations (early adulthood, and early and late middle age) in a community sample.

METHODS

Subjects (653 men and women aged around 23 years, 754 aged around 43 years, 722 aged around 63 years) completed home interviews with nurses as part of an ongoing longitudinal community-based study of social factors and health. These included measures of suicidal ideation (thoughts), attitudes to traditional gender roles, and a validated measure of gender role orientation (masculinity and femininity scores).

RESULTS

The prevalence of serious suicidal thoughts was higher in early adulthood (10% men, 15% women) than in early (4% men, 8% women) and late (6% men, 5% women) middle age. In early adulthood only sex was significantly related to suicidal thoughts, with women at higher risk (adjusted OR 1.74, 95% CI 1.01-3.00). In early middle age masculinity scores were negatively related to suicidal thoughts (adjusted OR for each unit increase in score 0.65: 95% CI 0.46-0.93), and more traditional views on gender roles were positively associated with suicidal thoughts (adjusted OR 1.48: 95% CI 1.07-2.04). In late middle age trends were in the same direction as in early middle age, but were not statistically significant. Femininity scores were unrelated to serious suicidal thoughts at any age.

CONCLUSION

The high rates of suicidal thoughts amongst men and women in early adulthood point to the importance of understanding mental health problems at this age. The results raise a number of questions and suggest that suicide researchers should pay more attention to gender roles and attitudes in older adults.

Trends in adolescent suicide mortality in the WHO European Region

Trends in adolescent suicide rates (15-19 years) from 1979 to 1996 were compared with suicide trends in individuals of 20 years and over in 30 countries and with trends in rates of deaths due to undetermined causes in adolescents in 17 countries of the WHO European Region. In 21 of the 30 studied countries, male adolescent suicide rates increased during the study period (highest increases in Belarus, Kazakstan and Ireland) accompanied by far less increases or decreases in suicide rates of males of 20 years and over. Part of the observed increases in Sweden, Ireland and Greece can be attributed to improved suicide statistics, while increases in Finland, Belgium, Bulgaria and the United Kingdom can be even higher due to the rising classification of deaths as "undetermined". In Portugal, decreasing suicide trends seem to be misinterpreted by ignoring the vast increases in rates of undetermined deaths. Female adolescent suicide rates rose less markedly than in males in 18 countries, with the exception of strong increases in Norway, Ireland. Increases in female adolescent suicide rates were marginally affected by changes in classification practices and were accompanied primarily by declining suicide rates in females of 20 years and over.

Suicides and suicide attempts in emergency medicine

OBJECTIVE

In emergency medicine, suicides and attempted suicides represent a major challenge for emergency physicians (EPs) and paramedics, both in terms of psychiatric and somatic treatment. To date no investigations have been performed to determine prevalence rates, method of suicide or attempted suicide, and the problems faced by EPs when treating these patients. This investigation presents a first evaluation of the complete emergency protocols from a major German city focusing on suicide and parasuicide.

METHODS

A retrospective analysis of all EP protocols from 1995 in the city of Hamburg was performed. All protocols were evaluated with respect to suicide parasuicide and suicidal ideation. Demographic data and information on method of suicide or attempted suicide, severity of illness, and underlying psychiatric disorder were extracted from the protocols.

RESULTS

A total of 26,347 emergency protocols were evaluated. Suicide and attempted suicide were considered either certain, probable, or possible in 743 cases (2.8%). Suicide was committed in 171 cases and attempted were made by 572 individuals. More men committed suicide in all age groups. By far the highest number of suicide attempts were by young men between 18 and 39 years of age. Hanging was the most commonly used method of completed suicide (41%), followed by jumping from a height (21%). The methods of intoxication with medication (54%) and illegal drugs (17%) clearly prevailed in suicide attempts. Documentation of suicides and attempted suicides was revealed to be unsatisfactory. Underlying psychiatric disorders were scarcely recorded.

CONCLUSION

In emergency medicine, the incidence of suicide or the attempt to commit suicide is small, yet disturbing. The frequency assessed may be too low as result of methodology. There is a need to improve the education of emergency physicians and paramedics in this area, and there is a need for data to be collected in a prospective design.

A global view of suicidal behaviour

Suicidal behaviour is a major public health problem. There is no one explanatory theory of suicidal behaviour, and various combinations of sociological and biological/medical interventions are required to reduce associated mortality and morbidity. The importance of primary prevention varies from community to community, and may have an impact at the population level. However, individual suicidal persons always require optimum assessment and management and that is usually provided by primary care and emergency physicians. This paper provides an overview of issues to be addressed in the assessment and management of suicidal patients.

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.
