A case-control study of psychosocial risk and protective factors of self-immolation in Iran

Motivations for suicide attempts and risk factors among youths in Western Iran: A cross-sectional study

Background and Aims

Suicide attempts are a fundamental problem in health care systems and are known for their complex and multifaceted nature. This study aimed to explore the reasons for suicide attempts and to identify associated factors in western Iran.

Methods

In Asadabad, western Iran, a cross-sectional study was carried out between April 2020 and March 2021. A nonrandom sampling method was used to select 110 participants, ages 15-35. Structured questionnaires such as the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI-II), and the Suicide Motivation Scale (IMSA) were used to gather the data. Multiple linear regression, one-way analysis of variance, Pearson's correlation coefficient, and independent t tests were all used in the data analysis.

Results

The majority of participants (59.1%) were female, with a mean age of 25.78 years. The most common reason for suicide attempts (43.6%) was family issues, and the most popular means (66.4%) were pills and medication. Eighty-nine percent of participants had symptoms of depression. The mean scores were calculated for motivation for suicide attempts (32.46 ± 16.11), depression (34.60 ± 20.50), and anxiety (34.14 ± 15.69). The analysis showed that the motivation for suicide attempts and anxiety was greater in single persons than in married and divorced persons (p < 0.05). Motivation for suicide attempts was also greater in low- to middle-income individuals with a history of divorce (p < 0.05). The multiple regression model showed that anxiety, sex, education, and medical history significantly influenced the motivation for suicide attempts (p < 0.001).

Conclusion

The results showed that a wide range of social, economic, and cultural factors and psychiatric disorders, including anxiety and depression, are involved in suicide attempts. This study aimed to design interventions and strategies to prioritize mental health, improve life skills to control stressful events, and focus on high-risk groups (women, married people, people with low education levels, and those with a history of physical and mental illnesses) for suicide prevention in health promotion programs.

Suicide attempts and deaths by self-immolation: A population-based study in Fars (Iran), 2011-2019

Background: Self-immolation is a leading public health challenge with a relatively high mortality, especially in some low- and middle-income countries. This study aimed to investigate epidemiological factors of attempts and completed suicide by self-immolation during 2011-2019 in Fars province (Iran). Materials and methods: This retrospective cross-sectional study included 506 cases of attempted self-immolation suicide during 2011-2019 in Fars province (Iran). Demographic characteristics and suicide information were collected from the Fars Suicide Surveillance System. The first fatality rate and age-standardized mortality rates were calculated. Then, chi-square tests were performed to evaluate suicide trends and examine differences between qualitative variables and outcomes. Logistic regression was used to identify factors associated with self-immolation death. Result: The mean age of study participants was 32.11 ± 14.04 years. The highest age-standardized rates of attempt and completed self-immolation suicide were seen in the age group 25-34 years. The fatality rate of suicide by self-immolation was 61.89%, and the risk of death was around three times higher in people with a history of suicide attempts compared to those who had no history of suicide attempts. However, a family history of suicide attempts was shown to be a protective factor against completed self-immolation suicide. Conclusion: The rate of self-immolation is higher in women and young adults. The results of our study can assist health policy-makers to design comprehensive plans and determine the necessary strategies aimed at identifying vulnerable people, then preventing self-immolation suicide.

Self-inflicted Burn Injury Is Independently Associated With Increased Mortality in a More Economically Developed Country: A Propensity Score Matching Analysis

Self-inflicted burn accounts for considerable morbidity and mortality in more economically developed countries, and there is a substantial debate regarding the pathophysiological relevance between self-inflicted burns and unfavorable outcomes. To validate whether self-inflicted injury is an independent predictor of high mortality regardless of the severity of burn, they conducted a retrospective observational study using the Japan Trauma Data Bank, a nationwide database including over 200 major tertiary care centers. Among 2006 patients with burn who had arrived at collaborating centers between 2004 and 2016, they included patients aged ≥15 years, those who did not present with cardiopulmonary arrest upon arrival, and those who had ≥10 percent total body surface area burns. Patients with missing survival data or unknown mechanism of injury were excluded. In total, 1094 patients were eligible, of whom 222 (20.3 percent) had self-inflicted burns. The patients were divided into the self-inflicted and non-self-inflicted groups, and propensity score was calculated using the demographic information of the patients, injury variables, time from injury to hospital arrival, and other survival predictors. Via a propensity score matching, 98 pairs were selected, and the self-inflicted group had a higher mortality than the non-self-inflicted group (43.9 vs 28.6 percent, hazard ratio = 1.77; 95% confidence interval = 1.10-2.86; P = .02). Inverse probability weighting and multivariate logistic regression were performed as sensitivity analyses, and results validated that self-inflicted burn was independently associated with increased in-hospital mortality. Therefore, patients with self-inflicted burns should receive judicious management, regardless of burn injury severity.

Association of suicidal behavior with exposure to suicide and suicide attempt: A systematic review and multilevel meta-analysis

BACKGROUND

Exposure to suicidal behavior may be associated with increased risk of suicide, suicide attempt, and suicidal ideation and is a significant public health problem. However, evidence to date has not reliably distinguished between exposure to suicide versus suicide attempt, nor whether the risk differs across suicide-related outcomes, which have markedly different public health implications. Our aim therefore was to quantitatively assess the independent risk associated with exposure to suicide and suicide attempt on suicide, suicide attempt, and suicidal ideation outcomes and to identify moderators of this risk using multilevel meta-analysis.

METHODS AND FINDINGS

We systematically searched MEDLINE, Embase, PsycINFO, CINAHL, ASSIA, Sociological Abstracts, IBSS, and Social Services Abstracts from inception to 19 November 2019. Eligible studies included comparative data on prior exposure to suicide, suicide attempt, or suicidal behavior (composite measure-suicide or suicide attempt) and the outcomes of suicide, suicide attempt, and suicidal ideation in relatives, friends, and acquaintances. Dichotomous events or odds ratios (ORs) of suicide, suicide attempt, and suicidal ideation were analyzed using multilevel meta-analyses to accommodate the non-independence of effect sizes. We assessed study quality using the National Heart, Lung, and Blood Institute quality assessment tool for observational studies. Thirty-four independent studies that presented 71 effect sizes (exposure to suicide: k = 42, from 22 independent studies; exposure to suicide attempt: k = 19, from 13 independent studies; exposure to suicidal behavior (composite): k = 10, from 5 independent studies) encompassing 13,923,029 individuals were eligible. Exposure to suicide was associated with increased odds of suicide (11 studies, N = 13,464,582; OR = 3.23, 95% CI = 2.32 to 4.51, P < 0.001) and suicide attempt (10 studies, N = 121,836; OR = 2.91, 95% CI = 2.01 to 4.23, P < 0.001). However, no evidence of an association was observed for suicidal ideation outcomes (2 studies, N = 43,354; OR = 1.85, 95% CI = 0.97 to 3.51, P = 0.06). Exposure to suicide attempt was associated with increased odds of suicide attempt (10 studies, N = 341,793; OR = 3.53, 95% CI = 2.63 to 4.73, P < 0.001), but not suicide death (3 studies, N = 723; OR = 1.64, 95% CI = 0.90 to 2.98, P = 0.11). By contrast, exposure to suicidal behavior (composite) was associated with increased odds of suicide (4 studies, N = 1,479; OR = 3.83, 95% CI = 2.38 to 6.17, P < 0.001) but not suicide attempt (1 study, N = 666; OR = 1.10, 95% CI = 0.69 to 1.76, P = 0.90), a finding that was inconsistent with the separate analyses of exposure to suicide and suicide attempt. Key limitations of this study include fair study quality and the possibility of unmeasured confounders influencing the findings. The review has been prospectively registered with PROSPERO (CRD42018104629).

CONCLUSIONS

The findings of this systematic review and meta-analysis indicate that prior exposure to suicide and prior exposure to suicide attempt in the general population are associated with increased odds of subsequent suicidal behavior, but these exposures do not incur uniform risk across the full range of suicide-related outcomes. Therefore, future studies should refrain from combining these exposures into single composite measures of exposure to suicidal behavior. Finally, future studies should consider designing interventions that target suicide-related outcomes in those exposed to suicide and that include efforts to mitigate the adverse effects of exposure to suicide attempt on subsequent suicide attempt outcomes.

Drivers and consequences of self-immolation in parts of Iran, Iraq and Uzbekistan: A systematic review of qualitative evidence

OBJECTIVES

The prevalence of self-immolation is significantly higher in some Middle Eastern and Central Asian Islamic countries than in Western countries. Self-immolation typically occurs among females and can be either an attempt at suicide or an act of protest. This systematic review examined the drivers and consequences of self-immolation in Asian Islamic countries from the perspective of those affected by it, including survivors, family and health care staff in order to understand its higher prevalence in these countries.

METHOD

A systematic review of qualitative studies was conducted in June 2018, using five electronic databases: PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), EMBASE, Scopus and PsycINFO. Of the 236 papers identified, seven met the inclusion criteria. Authors independently rated the reporting of included qualitative studies and thematic analysis was used to analyse the data.

RESULTS

The drivers of self-immolation included marital and familial conflict, male-dominated culture, mental health disorders and economic and social factors. Survivors chose self-immolation in order to express their sense of a lack of control and mostly utilised this method due to its accessibility. The consequences of self-immolation were social isolation, regret, and physical and psychological impacts.

CONCLUSIONS

The reasons for self-immolation, its prevalence and the demographics of those who choose this means vary significantly between Asian Islamic and Western countries. This review confirmed the impact of culture, tradition, and societal structures and relationships on people's decisions to self-immolate. Education about the consequences of self-immolation may reduce the use of this method.

A study of Kurdish women's tragic self-immolation in Iran: A qualitative study

Self-immolation is one of the most painful methods of suicide which is widespread among women in Kurdish regions of Iran. The present study aimed to explore the causes and sociocultural groundwork of choosing self-immolation methods by women in Kurdish regions of Iran. This present study was conducted using a qualitative approach and conventional content analysis. The research population included women who self-immolated and were rescued in Kurdish regions of Iran. The data collection method was a deep interview as well as observation. The sampling method was based on objective and snowball sampling. The data collection continued to theoretical saturation, the number of participants reached 25 in the end, and Lincoln and Guba criteria were used to strengthen the research. From the analysis of the data obtained in this study, the 8 sub-themes related to cause of suicide attempt from the participants' viewpoints including unbridled coherence, lack of supportive social and environmental structures, economic pressure, aggravation of violence, humiliated ego, dominance of modern values over the local and indigenous ones, incoherent family, and giving up on changing conditions as well as 6 sub themes based on the cause of choosing the method of self-immolation including protesting, frightening the family, catching more attention, championing and showing courage, inducing more guilty feelings in the family and society, fashion or imitation, and easy access were revealed. Self-immolation is one of the most important problems in the Kurdish regions of Iran, which is rooted in various economic, social, psychological and cultural causes. To reduce this social harm, there is a need for comprehensive programs that cover all dimensions.

The trend of burn mortality in Iran - A study of fire, heat and hot substance-related fatal injuries from 1990 to 2015

INTRODUCTION

Burn injuries are a major cause of preventable mortality worldwide. To implement preventive strategies, a detailed understanding of the rate and trend of fatal burn injuries is needed. The aim of this study was to determine the rate and trend of burn mortality at national and province level in Iran from 1990 to 2015.

MATERIALS AND METHODS

The data were retrieved from various sources: the Death Registration System, cemetery databases, the Demographic and Health Survey and three national population and housing censuses. ICD-10 codes were converted to Global Burden of Disease (GBD) codes for comparability. After addressing the incompleteness of death data, statistical methods such as spatio-temporal modelling and Gaussian Process Regression (GPR) were applied to estimate the levels and trend of death and cause specific mortality.

RESULTS

The number of deaths due to burning across Iran was 80,625, with a male to female ratio of 0.88, 0.94 and 1.14 in 1990, 1995 and 2015, respectively. The annual percentage change of age-standardized death rate from 1990 to 2015 was -5.42% and -4.22% in women and men, respectively. The burn-related age-standardized mortality rate decreased considerably from 5.97 in 1990 to 1.74 per 100,000 in 2015. The mortality rate due to burns was highest among those aged more than 85 years, especially in Ilam province.

CONCLUSION

This study showed a decline in burn mortality in Iran from 1990 to 2015. Continued efforts to reduce the burden of burns are needed to accelerate this progress and prevent injuries.

Female Gender, Marital and Family Problems, and Feelings of Guilt Are Related to Self-Immolation Suicide Attempts

BACKGROUND

Self-immolation (SI) is considered one of the most painful, dramatic, and at the same time most inexplicable methods of suicide, with a high social impact. Prevalence rates are particularly high in Iran, and in north-western Iran specifically. Here, we report sociodemographic, psychological, and psychiatric characteristics of patients attempting self-immolation (PSIs), compared to patients with accident burns (PABs).

METHOD

Patients referred to the Burns Emergency Unit of the Besat Hospital (Hamadan, Iran) were enrolled in the present study between winter 2015 and summer 2016. After burn-related treatments and surgery, a thorough interview was undertaken covering sociodemographic characteristics, burn-related information, and psychiatric background.

RESULTS

A total of 79 patients were enrolled. Among these, 19 (31.7%) had attempted suicide via SI. Compared to the PABs, the PSIs were predominantly females; they reported family and marital problems as the main triggers for SI. The psychiatric interviews indicated that PSIs often suffered from major depressive disorders, adjustment disorders, and bipolar disorders. The prevailing feelings reported were guilt and shame. A binary logistic regression showed that feelings of guilt and marital and family problems predicted SI.

CONCLUSIONS

The prevalence of SI was surprisingly high. Marital and family conflicts as a proxy for highly distressing social interactions, along with female gender and feelings of guilt and shame were strongly associated with SI. Family and couple counseling specifically tailored to difficulties experienced by women might reduce the risk of SI.

Substance use and suicidal ideation and behaviour in low- and middle-income countries: a systematic review

Background

Understanding relationships between substance use and suicidal ideation and behaviour (SIB) has important public health implications for suicide prevention in low- and middle-income countries (LMICs), where 75% of suicides occur. This systematic review explored the associations between substance use and SIB in LMICs.

Methods

We searched five databases using a combination of keywords for substance use, SIB and LMICs to identify English-written quantitative studies published between January 2006 and February 2016. Data were extracted to provide an overview of what is known about the topic, highlight gaps in the literature, and explore the implications of current knowledge for suicide prevention. Studies included in the review were assessed for methodological quality using the Scottish Intercollegiate Guidelines Network checklist.

Results

Analysis of included studies (N = 108) demonstrated a consistent positive association between substance use and SIB across all substances (i.e. alcohol, tobacco, cannabis, illicit drugs, non-medical use of prescription drugs), all substance use dimensions (i.e. intoxication, use, and pathological use) and all SIB dimensions (i.e. suicidal ideation, non-fatal suicidal behaviour, and suicide). Most of the available research evidence comes from upper-middle-income countries, only 22% comes from lower-middle-income and low-income countries. Most studies focused on alcohol and tobacco, while neglecting substances such as cannabis, opioids, sedatives, stimulants, misuse of prescription medication, inhalants, and hallucinogens. Most of the studies employed a cross-sectional design, were conducted within a risk-factor paradigm, and provided little information about the potential interaction between variables.

Conclusions

Public health suicide prevention policy and research in LMICs should take account of the fact that: substance use is a potentially modifiable risk factor; assessment and management of substance use is integral to the care of at-risk patients; reducing consumption and hazardous use of substances in LMICs is important for suicide prevention; and research needs to be expanded to include more theory driven research that focuses on all substance use dimensions and SIB dimensions, while employing more sophisticated statistical methods.

Factors associated with the choice of suicide method in Kermanshah Province, Iran

BACKGROUND

Identification of factors in the choice of suicide methods is important in understanding the phenomenon.

OBJECTIVES

We aimed to quantify the effect of gender, age, living area, education level and marital status on the choice of suicide method among residents of Kermanshah province in the west of Iran.

DESIGN

A cross-sectional study of all completed suicides from March 2006 to September 2013.

SETTING

Kermanshah Province, Iran.

METHODS

Data were extracted from suicide forms in the electronic files of the Forensic Medicine Organization. A total of 1901 (1138 men), suicide cases were identified. After preliminary analysis, a multinomial logistic model was fitted to the data to test and quantify the impact of each influential factor on the choice of suicide method. The relative risk of each suicide method over hanging as the reference method was estimated by calculating relative-risk ratios from the multinomial logistic model.

MAIN OUTCOME MEASURES

Relative risk of suicide by self-immolation, drug and toxic poisoning and firearms.

RESULTS

We found that women are at a higher relative risk than men for suicide by self-immolation, intentional drug poisoning and toxic poisoning. The relative risk of suicide by self-immolation and intentional drug poisoning was higher for urban residents and young individuals. On the other hand, men and rural residents were at higher relative risk of suicide by firearm.

CONCLUSIONS

In Kermanshah province, the impact of rapid social changes on women and the availability of firearms in rural areas and drugs in urban households require more attention in any suicide prevention planning.

LIMITATIONS

The lack of data prevented analysis of factors that may be more influential in choosing suicide.
