Marital status and suicidal behavior in South Asia: A systematic review and meta-analysis

Background and Aims

The connection between marital status and suicidal behavior has been poorly assessed in South Asia. We aimed to see the proportion of marital status in individuals with suicidal behavior in South Asian countries.

Methods

We followed PRISMA guidelines and registered the protocol in advance (PROSPERO 2023 CRD42023399906). A systematic search was conducted in Medline, Embase, and PsycINFO. Meta-analyses were performed to pool the proportion of married individuals with suicidal behavior (total [suicide + suicide attempts], suicide, and suicide attempt) in South Asian countries. We considered suicidal behavior consist of suicide and suicide attempts (nonfatal).

Results

Our search identified 47 studies for this review from 6 countries published from 1999 to 2022 with a sample size ranging from 27 to 89,178. The proportion of married individuals was 55.4% (95% CI: 50.1-60.5) for suicidal behavior, 52.7% (95% CI: 44.5-60.7) for suicides, and 43.1 (95% CI: 32.9-53.9) for suicide attempts. The proportion of married persons among suicide attempts varied significantly across countries (p = 0.016) which was highest (61.8%; 95% CI: 57.2-66.2) in India, followed by Bangladesh (52.5%; 95% CI: 41.8%-62.9%) and Pakistan (45.1%; 95% CI: 30.9-59.9). The pooled proportions did not differ significantly in relation to the quality of the studies (p = 0.633).

Conclusion

This review identified married persons died more than others by suicide in South Asian countries while single persons attempted suicide than married. As the current study did not assess any cause-and-effect association, a cautious interpretation is warranted while considering married marital status as a risk factor.

Pesticides and passion: a qualitative psychological autopsy study of suicide in Guyana

Background

The suicide rate in Guyana has consistently ranked in the top ten globally, yet there is only limited literature related to the context in which these suicides occur. This study aims to better understand the psychosocial circumstances and characteristics of suicides in Guyana.

Methods

This case series study utilised a qualitative psychological autopsy method. One to three informants per deceased person (N = 31) were interviewed regarding the lives of 20 Guyanese who died by suicide (14 M, 6 F, aged 10-74 years). Interpretative Phenomenological Analysis was utilised for the data.

Findings

Four superordinate themes were identified: Interpersonal Conflict, Trauma, Health, and Unknown Reasons. Interpersonal conflict included subordinate themes of Domestic Abuse, Marital Separation, and Financial Disputes. Health included subordinate themes of Physical Health and Mental Health. Pesticide poisoning was the method used by Guyanese people whose suicide was triggered primarily by interpersonal conflict.

Interpretation

The findings illustrate the complexities of suicide in Guyana and the importance of adopting a biopsychosocial perspective to suicide prevention. Suicide prevention should include mental health and suicide literacy training of medical professionals. It is recommended that the importation of highly toxic pesticides be restricted, and that less toxic substitutes be promoted. Convenience sampling, recall bias, and limited informants are limitations of this study. Future research should focus on suicidal behaviour using larger sample sizes.

Funding

This research was supported by an Australian Government Research Training Program Scholarship through Griffith University Australia.

Changes in method specific suicide following a national pesticide ban in India (2011-2014)

BACKGROUND

This paper investigates whether declines in suicide by insecticide poisoning in India following a national ban on endosulfan in 2011were associated with changes in other methods of suicide and total suicide rates.

METHOD

Method-specific suicide rates between 2001-2014 were calculated using National Crime Records Bureau (NCRB) data by sex, age group and region, with observed rates compared to expected rates for the period post-2011.

RESULTS

There were an estimated 20,146 fewer male and 8,418 fewer female suicides by insecticide poisoning and 5542 fewer male and 2679 fewer female suicides by all other methods following the national endosulfan ban. Contemporaneously, an estimated 92% (23,812) of male and 60% (6,735) of female suicides prevented by insecticide poisoning and all other methods were offset to increases in suicides by hanging and other poisoning. Joinpoint regression indicated a decrease in suicide by insecticide poisoning following the endosulfan ban (annual percentage change (APC) of -12.18 among males and -11.89 among females between 2010-2014) while an increase in male suicide by hanging was noted between 2009-2014 (APC of 7.05).

LIMITATION

Suicide rates based on the NCRB data might be an underestimation of the true suicide rates.

CONCLUSION

Declines in suicide by insecticide poisoning were largely offset by an increase in hanging suicides among males, however, this phenomenon was much less prominent in females and contributed to declines in total female suicide rates. Prevention strategies must continue to focus on pesticide bans with simultaneous attention on hanging prevention policies to reduce overall suicide rates in India.

Suicide-related interpersonal needs of young Iranian people: A preliminary validation of thwarted belongingness and perceived burdensomeness constructs

The aim of the current study was to validate the Interpersonal Needs Questionnaire (INQ-15) and to test its reliability in Persian-speaking Iranian undergraduate students. In this cross-sectional study, 485 undergraduate students (age: 20.66 ± 1.42, 60% female) were assessed on the two subscales of perceived burdensomeness (PB) and thwarted belongingness (TB) and the Suicide Behavior Questionnaire-Revised (SBQ-R). Exploratory structural equation modelling (ESEM) confirmed the construct validity of INQ-14, excluding INQ#9. In addition, INQ#8, articulated in an equivalent Persian phrasing, loaded well on TB. The measurement model tested by confirmatory factor analysis (CFA) suggested INQ#11 to be eliminated, resulting in INQ-13-P to consist of PB and TB-7. The internal consistency and convergent/discriminant validity were established. The concurrent validity of PB was solidly established in terms of past year suicidal ideation (PY-SI) above and beyond anxiety, depression, prior suicidality, and TB-7. The effect of PB on PY-SI was stronger, where prior suicidality had already occurred or the perceived likelihood of future suicide (PLFS) was high. Moreover, TB-7 could only indicate PY-SI, where prior suicidality had already occurred or PLFS was high, albeit when PB was omitted. The interaction term was significant; however, beyond anxiety and depression, the effect of TB-7 on PY-SI was significant where PB was very high (n = 40, 8.25%). Therefore, future studies can utilize INQ-13-P as a valid and reliable instrument in Persian-speaking populations. However, further studies should examine the construct validity of TB and its relationship with suicide ideation in different populations.

Do individuals follow up with mental health services after a suicide attempt? Findings from the assertive management of attempted suicide service, Bengaluru, India

OBJECTIVE

There is limited information from India on whether individuals follow up with mental health services after a suicide attempt. The objective of this study was to determine follow-up rates after a suicide attempt with mental health services of those individuals treated as part of the assertive management of attempted suicide service in a general hospital in Bengaluru, India.

MATERIALS AND METHODS

Records from 284 persons from January 2016 to December 2016 were analyzed to ascertain their follow-up rates with mental health services after a suicide attempt.

RESULTS

After discharge, 25% individuals followed up on a single occasion with mental health services. Individuals with a psychiatric diagnosis were significantly more likely to follow up with mental health services as compared to those without a psychiatric diagnosis (P < 0.011, odds ratio: 2.875, confidence interval at 95%: 1.276-6.481). 90.8% were contacted through telephone as part of aftercare.

CONCLUSIONS

Most individuals in India, especially those without a psychiatric diagnosis, do not follow up with mental health services after a suicide attempt. Periodic telephonic contacts are a useful aftercare strategy to reach out to this high-risk population. Limitation of this study is that findings are from an urban general hospital setting.

Facets of clinical stigma after attempted suicide in Mumbai, India

Community stigma studies may neglect clinically relevant experience and views of stigma that are important features of mental health problems. After attempting suicide, patients in a hospital emergency ward in Mumbai, India, were assessed for stigma referring to underlying prior problems motivating their deliberate self-harm (DSH) event, the DSH event itself and serious mental illness generally based on both anticipated community views and distinctive personal views. In this cultural epidemiological study of 196 patients, assessment items and four corresponding indexes were analysed and compared on a four-point scale, 0 to 3, for prominence of indicated stigma. Narratives from patients with high, low and discordant levels of stigma for prior problems and DSH events were analysed and compared. Disclosure, critical opinions of others and problems to marry were greater concerns for DSH events than prior problems. Problem drinking, unemployment, and sexual or financial victimization were common features of prior problems. Impulsivity of the DSH event and externalizing blame were features of lower levels of stigma. Ideas about most people's views of serious mental illness were regarded as more stigmatizing than patients' prior problems and DSH event; patients' personal views of serious mental illness were least stigmatizing. Findings suggest linking suicidality and stigmatized mental illness may discourage help seeking. Suicide prevention strategies should therefore emphasize available help needed for severe stress instead of equating suicidality and mental illness. Findings also indicate the relevance of assessing clinical stigma in a cultural formulation and the value of integrated qualitative and quantitative stigma research methods.

Reporting of ethics in peer-reviewed verbal autopsy studies: a systematic review

Introduction

Verbal autopsy (VA) is a method that determines the cause of death by interviewing a relative of the deceased about the events occurring before the death, in regions where medical certification of cause of death is incomplete. This paper aims to review the ethical standards reported in peer-reviewed VA studies.

Methods

A systematic review of Medline and Ovid was conducted by two independent researchers. Data were extracted and analysed for articles based on three key areas: Institutional Review Board (IRB) clearance and consenting process; data collection and management procedures, including: time between death and interview; training and education of interviewer, confidentiality of data and data security; and declarations of funding and conflict of interest.

Results

The review identified 802 articles, of which 288 were included. The review found that 48% all the studies reported having IRB clearance or obtaining consent of participants. The interviewer training and education levels were reported in 62% and 21% of the articles, respectively. Confidentiality of data was reported for 14% of all studies, 18% did not report the type of respondent interviewed and 51% reported time between death and the interview for the VA. Data security was reported in 8% of all studies. Funding was declared in 63% of all studies and conflict of interest in 42%. Reporting of all these variables increased over time.

Conclusions

The results of this systematic review show that although there has been an increase in ethical reporting for VA studies, there still remains a large gap in reporting.

New challenges for verbal autopsy: Considering the ethical and social implications of verbal autopsy methods in routine health information systems

Verbal autopsy (VA) methods are designed to collect cause-of-death information from populations where many deaths occur outside of health facilities and where death certification is weak or absent. A VA consists of an interview with a relative or carer of a recently deceased individual in order to gather information on the signs and symptoms the decedent presented with prior to death. These details are then used to determine and assign a likely cause-of-death. At a population level this information can be invaluable to help guide prioritisation and direct health policy and services. To date VAs have largely been restricted to research contexts but many countries are now venturing to incorporate VA methods into routine civil registration and vital statistics (CRVS) systems. Given the sensitive nature of death, however, there are a number of ethical, legal and social issues that should be considered when scaling-up VAs, particularly in the cross-cultural and socio-economically disadvantaged environments in which they are typically applied. Considering each step of the VA process this paper provides a narrative review of the social context of VA methods. Harnessing the experiences of applying and rolling out VAs as part of routine CRVS systems in a number of low and middle income countries, we identify potential issues that countries and implementing institutions need to consider when incorporating VAs into CRVS systems and point to areas that could benefit from further research and deliberation.

Understanding Suicide Attempts Among Gay Men From Their Self-perceived Causes

Gay men are at higher risk of suicidality. This paper describes the causes of suicide attempts as perceived by the men themselves and analyzes their impact on severity and recidivism. Mental health surveys conducted among gay men in Geneva, Switzerland, from two probability-based time-space samples in 2007 and 2011, were merged to yield a combined sample N = 762. Suicide ideation, plans, and attempts were assessed, and respondents who had ever attempted suicide answered open questions about perceived causes which were coded and categorized for analysis within the framework of cultural epidemiology. In all, 16.7% of the respondents reported a suicide attempt in their lifetime (59.5% of them with multiple attempts). At their latest attempt, over two thirds asserted intent to die, and half required medical assistance. There was a wide variety of perceived causes, with most individuals reporting multiple causes and many of the most common causes cited at both the first and most recent subsequent attempts. Social/inter-personal problems constitute the most prominent category. Problems with love/relationship and accepting one's homosexuality figure consistently among the top three causes. Whereas the former tend to be associated with weaker intent to die, the latter are associated with the strongest intent to die and reported at multiple attempts. Problems with family are among the most common perceived causes at first attempt but not at the most recent subsequent attempt. Nevertheless, they tend to be related to the strongest intent to die and the greatest medical severity of all the perceived causes. Ten percent of men attempting suicide cited depression as a cause. Although it tended to be associated with weaker intent to die, depression was most likely to be reported at multiple attempts. Respondent-driven assessment yielded both common and idiosyncratic causes of suicide and their distinct effects. Some of these perceived causes are not prominent in the current literature, yet they have important implications for understanding risk and preventing suicide among gay men.

Explaining suicide: identifying common themes and diverse perspectives in an urban Mumbai slum

Rates, demographics and diagnostics, which are the focus of many studies of suicide, may provide an insufficient account without adequate consideration of psychological, social and cultural contexts and motives. Furthermore, reported explanations of suicide are shaped not only by events but also the relationship of survivor respondents explaining the suicide. An explanatory model interview for sociocultural autopsy has been used to assess underlying problems and perceived causes. This study in a low-income community of Mumbai in 2003-2004 compared accounts of the closest family survivors and more distant relationships. Our study design distinguished series-level agreement (i.e., consistency of accounts within a group) and case-level agreement for particular cases. Serious mental illness was the perceived cause reported by a respondent in either group for 22.0% of index suicides, but case-level agreement was only 6.0%. Regarding financial stressors, more closely related family respondents focused on acute stressors instead of enduring effects of poverty. Case-level agreement was high for marital problems, but low for other sources of family conflict. Tension was a feature of suicide reported in both groups, but case-level agreement on tension as a perceived cause was low (kappa = 0.14). The role of alcohol as a perceived cause of suicide had high series level agreement (46.0% in both groups) and case-level agreement (kappa = 0.60), suggesting comparable community and professional views of its significance. The study shows that it is relevant and feasible to consider general community patterns and particular survivor interests. Findings from this study recommend an approach to sociocultural autopsy to assess reasons for suicide in community studies. Findings clarify diverse views of underlying problems motivating suicide that should be considered to make mental health care more effective in assessing risk and preventing suicide.

Verbal autopsy completion rate and factors associated with undetermined cause of death in a rural resource-poor setting of Tanzania

BACKGROUND

Verbal autopsy (VA) is a widely used tool to assign probable cause of death in areas with inadequate vital registration systems. Its uses in priority setting and health planning are well documented in sub-Saharan Africa (SSA) and Asia. However, there is a lack of data related to VA processing and completion rates in assigning causes of death in a community. There is also a lack of data on factors associated with undetermined causes of death documented in SSA. There is a need for such information for understanding the gaps in VA processing and better estimating disease burden.

OBJECTIVE

The study's intent was to determine the completion rate of VA and factors associated with assigning undetermined causes of death in rural Tanzania.

METHODS

A database of deaths reported from the Ifakara Health and Demographic Surveillance System from 2002 to 2007 was used. Completion rates were determined at the following stages of processing: 1) death identified; 2) VA interviews conducted; 3) VA forms submitted to physicians; 4) coding and assigning of cause of death. Logistic regression was used to determine factors associated with deaths coded as "undetermined."

RESULTS

The completion rate of VA after identification of death and the VA interview ranged from 83% in 2002 and 89% in 2007. Ninety-four percent of deaths submitted to physicians were assigned a specific cause, with 31% of the causes coded as undetermined. Neonates and child deaths that occurred outside health facilities were associated with a high rate of undetermined classification (33%, odds ratio [OR] = 1.33, 95% confidence interval [CI] (1.05, 1.67), p = 0.016). Respondents reporting high education levels were less likely to be associated with deaths that were classified as undetermined (24%, OR = 0.76, 95% CI (0.60, -0.96), p = 0.023). Being a child of the deceased compared to a partner (husband or wife) was more likely to be associated with undetermined cause of death classification (OR = 1.35, 95% CI (1.04, 1.75), p = 0.023).

CONCLUSION

Every year, there is a high completion rate of VA in the initial stages of processing; however, a number of VAs are lost during the processing. Most of the losses occur at the final step, physicians' determination of cause of death. The type of respondent and place of death had a significant effect on final determination of the plausible cause of death. The finding provides some insight into the factors affecting full coverage of verbal autopsy diagnosis and the limitations of causes of death based on VA in SSA. Although physician review is the most commonly used method in ascertaining probable cause of death, we suggest further work needs to be done to address the challenges faced by physicians in interpreting VA forms. There is need for an alternative to or improvement of the methods of physician review.

A lost cause? Extending verbal autopsy to investigate biomedical and socio-cultural causes of maternal death in Burkina Faso and Indonesia

Maternal mortality in developing countries is characterised by disadvantage and exclusion. Women who die whilst pregnant are typically poor and live in low-income and rural settings where access to quality care is constrained and where deaths, within and outside hospitals, often go unrecorded and unexamined. Verbal autopsy (VA) is an established method of determining cause(s) of death for people who die outside health facilities or without proper registration. This study extended VA to investigate socio-cultural factors relevant to outcomes. Interviews were conducted with relatives of 104 women who died during pregnancy, childbirth or postpartum in two rural districts in Indonesia and for 70 women in a rural district in Burkina Faso. Information was collected on medical signs and symptoms of the women prior to death and an extended section collected accounts of care pathways and opinions on preventability and cause of death. Illustrative quantitative and qualitative analyses were performed and the implications for health surveillance and planning were considered. The cause of death profiles were similar in both settings with infectious diseases, haemorrhage and malaria accounting for half the deaths. In both settings, delays in seeking, reaching and receiving care were reported by more than two-thirds of respondents. Relatives also provided information on their experiences of the emergencies revealing culturally-derived systems of explanation, causation and behaviour. Comparison of the qualitative and quantitative results suggested that the quantified delays may have been underestimated. The analysis suggests that broader empirical frameworks can inform more complete health planning by situating medical conditions within the socio-economic and cultural landscapes in which healthcare is situated and sought. Utilising local knowledge, extended VA has potential to inform the relative prioritisation of interventions that improve technical aspects of life-saving services with those that address the conditions that underlie health, for those whom services typically fail to reach.

Race/ethnicity and potential suicide misclassification: window on a minority suicide paradox?

BACKGROUND

Suicide officially kills approximately 30,000 annually in the United States. Analysis of this leading public health problem is complicated by undercounting. Despite persisting socioeconomic and health disparities, non-Hispanic Blacks and Hispanics register suicide rates less than half that of non-Hispanic Whites.

METHODS

This cross-sectional study uses multiple cause-of-death data from the US National Center for Health Statistics to assess whether race/ethnicity, psychiatric comorbidity documentation, and other decedent characteristics were associated with differential potential for suicide misclassification. Subjects were 105,946 White, Black, and Hispanic residents aged 15 years and older, dying in the US between 2003 and 2005, whose manner of death was recorded as suicide or injury of undetermined intent. The main outcome measure was the relative odds of potential suicide misclassification, a binary measure of manner of death: injury of undetermined intent (includes misclassified suicides) versus suicide.

RESULTS

Blacks (adjusted odds ratio [AOR], 2.38; 95% confidence interval [CI], 2.22-2.57) and Hispanics (1.17, 1.07-1.28) manifested excess potential suicide misclassification relative to Whites. Decedents aged 35-54 (AOR, 0.88; 95% CI, 0.84-0.93), 55-74 (0.52, 0.49-0.57), and 75+ years (0.51, 0.46-0.57) showed diminished misclassification potential relative to decedents aged 15-34, while decedents with 0-8 years (1.82, 1.75-1.90) and 9-12 years of education (1.43, 1.40-1.46) showed excess potential relative to the most educated (13+ years). Excess potential suicide misclassification was also apparent for decedents without (AOR, 3.12; 95% CI, 2.78-3.51) versus those with psychiatric comorbidity documented on their death certificates, and for decedents whose mode of injury was "less active" (46.33; 43.32-49.55) versus "more active."

CONCLUSIONS

Data disparities might explain much of the Black-White suicide rate gap, if not the Hispanic-White gap. Ameliorative action would extend from training in death certification to routine use of psychological autopsies in equivocal-manner-of-death cases.
