JOURNAL OF EDUCATION AND HEALTH PROMOTION 2024; 13:84. [PMID: 38720684 PMCID: PMC11078457 DOI: 10.4103/jehp.jehp_940_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Accepted: 08/28/2023] [Indexed: 05/12/2024]
Abstract
BACKGROUND There is tremendous variation in both the prevalence of suicide and the factors that contribute to its occurrence across geographic locations, cultures, and time. Therefore, the present study aims to identify the various socio-demographic risk factors and psychosocial stressors using population data. MATERIALS AND METHODS The countries that were included in the study were based on data from the World Health Organization. We considered the top ten suicide countries and the ten lowest suicide nations. We searched five global databases for the most recent socio-demographic data and data on psychosocial stressors during the period of August and September 2022. We analyzed the correlation between suicide rates and various factors, and we considered a P value of less than 0.05 to be statistically significant. RESULTS The correlation of suicide with sociodemographic factors like age (P 0.246), gender (male, P 0.357, and female, P 0.357), net enrolment rate (P 0.725), gender parity index (P 0.929), urban population percentage (P 0.571), marital status (male, P 0.345, and female, P 0.752), and literacy rate percentage (P 0.199) was not significant. The correlation of suicide with psychosocial stressors like unemployment percentage (P 0.552), alcoholism percentage (P 0.271), the prevalence of depression (P 0.523), the number of psychiatrists (P 0.605), the number of mental hospitals (r = -0.090, P 0.713), and the poverty rate percentage (P 0.538) were also not significant. CONCLUSION Suicide is a major public health issue, yet global suicide data is scarce. Sociodemographic factors like age, urbanization, and literacy rate were negatively correlated, whereas psychosocial stressors like unemployment, alcohol misuse, and poverty were positively correlated, but none were significantly associated.

Investigation of peripheral inflammatory biomarkers in association with suicide risk in major depressive disorder. Front Psychiatry 2024; 15:1321354. [PMID: 38347880 PMCID: PMC10859515 DOI: 10.3389/fpsyt.2024.1321354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 01/10/2024] [Indexed: 02/15/2024] Open
Abstract
Suicide is the most severe complication of major depressive disorder (MDD). Novel research assumes the role of immunological dysregulation in the background - several studies have reported alterations in the number of inflammatory cells related to both MDD and suicidality. There are currently no objective, routinely measured parameters to indicate suicidal vulnerability. However, altered inflammatory cell numbers and ratios have been proposed as potential biomarkers of suicide risk (SR). The present research aims to examine changes of these values related to increased SR in MDD as an assumed inflammatory state. We investigated laboratory parameters of psychiatric in-patients diagnosed with MDD (n = 101) retrospectively. Individuals with recent suicide attempt (SA) (n = 22) and with past SA (n = 19) represented the high SR group. MDD patients with no history of SA (n = 60) composed the intermediate SR group. We compared the number of neutrophil granulocytes, monocytes, lymphocytes, platelets, white blood cell count (WBC), neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), red blood cell distribution width (RDW) and erythrocyte sedimentation rate (ESR). Furthermore, we evaluated alterations of these parameters related to antidepressant (AD) and antipsychotic (AP) treatment, which have been proved to have anti-inflammatory effects. We found a significant increase in neutrophil granulocyte count, NLR, monocyte count, MLR, WBC and ESR in patients with recent SA compared to patients with no history of SA. Moreover, there was a significant elevation in monocyte count, MLR, ESR and RDW in patients with high SR compared to patients with intermediate SR. AD treatment resulted in a significant decrease in neutrophil granulocyte count and NLR, however, it did not affect monocyte count and MLR. Assuming immunological mechanisms in the background of MDD and suicidality, our findings support the role of NLR as a biomarker of acute SR, though its alterations may be masked by possible anti-inflammatory effects of AD treatment in the long term. However, MLR, a marker exhibiting changes which are not attenuated by pharmacotherapy, may be a possible indicator of both acute and long-term suicidal vulnerability.

[PMID: 38283486 PMCID: PMC10811436 DOI: 10.7759/cureus.51175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Accepted: 12/27/2023] [Indexed: 01/30/2024] Open
Abstract
Introduction Chronic stress breaches the normal homeostasis of the hypothalamic-pituitary-adrenal axis, leads to chronic adrenal fatigue, and causes hypertrophy and hyperplasia of the adrenal gland. The current study was carried out with the aim of observing the difference in gross morphological changes in the adrenals of people dying by suicide and from sudden death, as persons committing suicide are exposed to chronic stress (depression), while those dying suddenly are exposed to the acute stress of dying. Materials and methods The present analytical study was carried out in the Department of Forensic Medicine and Toxicology, Gandhi Medical College, Bhopal, India, after approval from the Institutional Ethics Committee (IEC). A total of 100 established cases of suicide with prominent autopsy findings and relevant history without signs of decomposition, aged 15-60 years, irrespective of gender, and a variable survival period (immediate death to within 24 hours) were selected. A total of 20 controls included those who died suddenly from an act other than suicide within 24 hours of the incident. Due consent was obtained from the relatives and police in the prescribed proforma. Kidneys, along with peri-renal fat and adrenal glands on both sides, were carefully removed and examined. Results A total of 25% of suicide victims reported a history of chronic stress, 13% self-destructive behavior, 3% untreated depression, and 8% reported financial or marital difficulties. The right adrenal gland was found to be heavier than the left in the control group. In addition, both left and right adrenal glands weighed more in males. Among the suicidal cases, the weight of the left adrenal gland was greater than that of the right, and the weight of the gland in males was higher than that in females. The difference in adrenal gland weight among males was significant in both case and control groups (combined p-value = 0.0001) but was insignificant in females, probably due to their disproportionate ratio in both groups. There was no significant relationship between adrenal gland weight and individual age or weight. However, adrenal gland weight in both groups was significantly associated with the height of the individual (p-value = 0.001 in the study group and < 0.05 in the control group). The difference in adrenal gland volume between the suicidal and control groups was not significant, indicating that the increase in size is not a differentiating criterion for acute and chronic stress. The relative adrenal gland weight was significantly higher in the suicidal group. Conclusion The external appearance of the adrenal gland may be regarded as a normal response to stress in relation to the mode of death. The left adrenal gland is more likely to show an increase in weight in response to chronic stress. The weight of the adrenal gland in both groups is significantly associated with the height of the deceased. Relative adrenal weight can be considered as specific for suicidal cases exposed to chronic stress. However, the volume of the adrenal gland may be considered an unreliable criterion in the differentiation of chronic stress from acute stress.

Abstract
OBJECTIVE Suicide is a significant public health concern worldwide, and efforts to prevent it are crucial. This study aims to assess suicide ideation among transgender individuals in Iran. A cross-sectional design was used, with 235 transgender participants recruited through snowball sampling across Iran. The data collection included a questionnaire containing demographic inquiries, while the Beck Scale for Suicide Ideation was employed to gather data. Descriptive and analytical statistics were performed using SPSS software. RESULTS The findings indicate that the prevalence of suicidal ideation among the transgender individuals in the study was 83%, with a mean score of 12.8 ± 8.8 on the suicide ideation scale. Individuals with lower levels of education, younger age, unemployment, and being divorced or single demonstrated significantly higher scores compared to others (p < 0.05). This study highlights the high prevalence of suicidal ideation among Iranian transgender individuals, particularly among those with lower age and education levels, as well as those who have not undergone gender reassignment surgery.

Abstract
Suicide attempts by self-poisoning have become a critical health problem. This study aimed to investigate the trend, incidence, and the associated risk factors of suicide attempts by self-poisoning. A total of 7398 Egyptian patients were analyzed. The trend of suicide attempts by self-poisoning was analyzed using 6745 patients over four registry years from January 1, 2016, to January 1, 2020. Then, the associated risk factors behind attempted suicide by self-poisoning from January 1, 2019, to January 1, 2020, were assessed using 2523 suicide attempters by self-poisoning, 201 fatalities by self-poisoning, and another 653 survivors of accidental poisoning. Results showed a rising trend of suicide attempts by self-poisoning over the studied years. The incidence of suicide attempts through deliberate self-poisoning represented 26.63/1,000 (CI95%: 25.63–27.86) to the admitted patients and 26.10/100,000 (CI95%: 25.10–27.14) to the regional population. The death rate due to suicide attempts by self-poisoning was 2.08/100,000 (1.90–2.49). The case fatality rate and the proportionate mortality rate for suicide by self-poisoning were 7.38% (CI95%: 6.45–8.42) and 14.11% (CI95%: 12.4–16.0) respectively. Multivariate analysis revealed that attempted suicide by self-poisoning was predicted among patients aged <25 or 25–40 years old (OR = 27.49, CI95%: 15.28–49.64 and OR = 59.42, CI95%: 32.76–107.77 respectively), those of low or moderate socioeconomic status (OR = 35.03, CI95%: 21.32–57.56 and OR = 14.11, CI95%: 10.86–18.43 respectively), students (OR = 2.91, CI95%: 1.57–5.43) and those living in rural residency (OR = 4.12, CI95%: 3.27–5.19). Suicide attempts by self-poisoning exhibited an incremental rise across time which raises a serious concern. Efforts should be directed to overcome the mentioned risk factors triggering suicide attempts by self-poisoning.

Abstract
BACKGROUND Media coverage of suicides in Nigeria appears to be explicitly descriptive and deviates from the recommended best practice. Despite these shortcomings, verifiable information provided by these media outlets could arguably, at the minimum, mirror the reality of the trends and patterns of suicidal behaviour in Nigeria. AIM This study aimed to analyse the trends and patterns of suicidal behaviour in Nigeria using media reports from 2016 to 2019. We examined the effect of gender and age groups on these trends and patterns of suicidal behaviour. SETTING The study was carried out in Nigeria. METHODS Qualitative content analysis was used to assess the content of each verifiable suicide event. In total, 336 verified suicide-related events were selected from 4365 media reports. Quantitative data were collected on age, gender, type of suicidal behaviour, method, place and motivation for suicidal behaviour. Data were analysed using the Statistical Package for the Social Sciences software. Fisher's exact test was used to examine the association between gender, age groups and other variables. p-value was set at ≤ 0.05. RESULTS Completed suicide was the most common reported suicidal behaviour. Hanging was the dominant reported method, followed by poisoning. Significant gender differences were observed between age groups (p < 0.001) and methods of suicidal behaviour (p < 0.001). Also, significant age differences were observed between the methods of suicidal behaviour (p < 0.001), places (p < 0.001) and motivations for suicidal behaviour (p < 0.001). CONCLUSION The study confirms that there are gender and age differences in the trends and patterns of suicidal behaviour in Nigeria.

Abstract
BACKGROUND Suicide is a global phenomenon and a major public health concern and 'it is possibly preventable if it is well understood'. AIM The article is an attempt to understand 'suicide in India' with the existing literature and the lacuna for the four decades. METHODS The information is collected from 270 articles on suicide research in India, published in various electronic data bases and different official sites as surprisingly the nation is with highest suicide mortality rate among all regional countries. RESULTS The review shows an increase in the number of articles on suicide in India over the period of time. Though the suicide mortality rate in India is significantly high, the number of intervention studies remains very minimal. India's understanding about 'the concept' remains questionable as the data from different sources for the same time period shows a huge disparity. Sex, age, socio-economic status, substance abuse, mental illness, medical illness, psychological and environmental stressors etc make individuals vulnerable to end their lives. CONCLUSION Appropriate official documentation and more qualitative studies would help in understanding the phenomena better. Intervention studies and policy level changes are the need of the hour to save the nation from the dangerous 'iceberg of suicide'.

Abstract
Previous meta-analyses conclude that psychological treatments are efficacious for emotional distress in breast cancer (BCa). However, the practical relevance of these meta-analyses is questionable; none focused specifically on clinically distressed patients or whether treatment effects were clinically significant. In a two-stage individual patient data (IPD) meta-analysis of 17 randomized controlled trials of manualized psychological treatments in BCa, we evaluated treatment efficacy in distressed BCa patients (n = 1591) using clinical significance and effect size analyses. Outcomes were anxiety, depression, and general distress, evaluated at post-treatment and follow-up. Moderators examined were treatment type, treatment format, therapists' profession, control condition, age, outcome measure, and trial quality. Treated patients were more likely than controls to recover from anxiety and general distress at post-treatment (14-15% more treated patients recovered), but not at mean 8-months follow-up. Overall recovery rates were low: across outcomes, at post-treatment, only 30-32% of treated patients and 15-25% of controls recovered; at follow-up, only 21-30% of treated patients and 18-35% of controls recovered. Small between-group effect sizes in favour of treatment were found across outcomes at post-treatment (g = 0.32-0.34) but not at follow-up. Across the different analysis methods, few moderator effects were found. More efficacious psychological treatments are needed for distressed BCa patients.

Abstract
BACKGROUND Suicides have become headline news in most developing countries and often feature on front pages with accompanying graphic pictures on prominent news portals. There has been an increased reportage of suicides by the Ghanaian news media. This study aims to shed light on the trend of online news media reporting of suicides, and the epidemiology of media reported suicides in Ghana. METHODS An online search was conducted for news media reports of suicides committed in Ghana. One hundred and forty-two (142) news media reported suicides spanning 1997 to 31st July 2019 were retrieved and included in the analyses. RESULTS The victims of suicides were predominantly male (85.92%), young (mean age = 34.81 ± 15.71 years; range 10-86 years). Suicide by hanging (67.94%), the use of firearms (18.32%), and self-poisoning (8.93%) were the common methods used by the victims. There has been increased online news media reportage of suicides in Ghana in the last 3 years; 2017 witnessed the highest reportage of 30 (21%) cases. Marital or relationships and family problems were commonly cited as the reasons for the commission of suicides; mental disorders, and financial problems were also cited as immediate triggers of the suicides by close relations of the victims. CONCLUSION There is an increased media reportage of suicides in Ghana, although this cannot be linked to a corresponding increase in suicide incidence. Interventions to decrease the risk of suicide among vulnerable populations (young adults) such as the identification of suicidal behavior, making mental healthcare services more accessible by integrating into the general healthcare service, public education, establishing a suicide hotline will be critical programs to help reduce suicide incidence in Ghana.

Abstract
Suicide is a serious public health problem in many countries and has always been a source of apprehension and quest to human mankind, which can be resolved with due diligence. Suicide is a hidden and silent epidemic, with many causative factors. Studying and researching on various causative factors have always been the subject of significance for the researchers. Psychiatric illnesses happen to be the primary reasons for the majority of suicide mortality cases. Not only this, there has been a consistent increase in the no. of cases of mental disorders as well as attempted and completed suicide cases. If one looks at global scenario, an approximate 70,000 people commit suicide, and further alarming is the fact that the rate of suicide attempt cases has gone up to 250% during last 18 years in conflict zones. Poisoning, hanging and self-immolation are some of the common methods to commit suicide. Physical and mental illness, disturbed emotional relationships and economic difficulties were the major reasons for suicide with the predisposed population being women, student and farmers. As per WHO's approximation, there is one suicide every minute and an attempted suicide every third second. It implies that the number of killed due to suicide is greater than that of the ones killed due to the armed conflict.

Abstract
OBJECTIVE The purpose of this study is to analyze epidemiological characteristics of suicide, as well as to emphasize possible risk factors. METHODS This is a retrospective study, covering the period of fifteen years (1996-2010), which aims at discovering the relevant factors which have an influence on suicidal behaviour. This research uses the data from the documentation of the Ministry of Internal Affairs of Serbia and Police Department in Kragujevac, hospitalization reports of patients treated at Psychiatric Clinic of the Clinical Centre Kragujevac, as well as the medical records of patients treated at the Health Centre Kragujevac. χ2 test was applied to examine the influence of all selected factors on incidence of suicide and for this purpose SPSS statistical software package was used. RESULTS The analysis has shown that during the given period average suicide rate reached 11.8 per population of 100,000. The male to female suicide ratio of 3.6:1 obtained through this study suggests that men (78.4%) are more prone to suicide than women (21.6%). The highest number of suicides has been found within the age group of 65-year-olds (31.2%), while for the youngest age group (15-24 years) the lowest prevalence of 8.8% has been determined. In other words, the youngest subjects are 3.5 times less likely to commit suicide than the participants of the oldest age group. During the given period suicide was most often committed by married males and females with primary school education than by employed and retired people. The research has also revealed that most suicides came from urban areas (52.0%) and that the most common method of suicide is hanging (60.8%), followed by suicide by firearms, jumping from height, poisoning, and drowning. CONCLUSION In order to prevent suicide, it is essential to collect and analyze all information concerning suicide victims.

Abstract
Depression is a leading cause of HIV/AIDS disease burden; it worsens health outcomes and quality of life. Addressing this problem requires accurate quantification of the extra burden of depression to HIV/AIDS in a given population, and knowledge of the baseline depression prevalence in the general population. There has been no previous study of depression in the general Cameroonian population. The current study attempts to address that important need. We used the Beck Depression Inventory-II to assess the prevalence and severity of depressive symptoms in 270 HIV-infected and seronegative Cameroonians. Univariate analyses showed a trend toward higher depressive symptoms among cases, compared to controls (p = 0.055), and among older subjects (>40 years), compared to younger subjects (≤40 years) (p = 0.059). Analysis of depression severity showed that 33.73% of cases had moderate-to-severe depressive symptoms, compared to 19.8% of controls (p<0.01). However, multivariable negative binomial regression analyses showed no effect of age, HIV status, CD4 levels, viral loads, ART, or opportunistic infections on the risk of depressive symptoms. Both univariate and multivariable regression analyses showed significantly higher risk of depressive symptoms among females compared to males; this was significant for both female controls and female cases. Female cases had significantly higher CD4 cell counts and lower viral loads, compared to males. Both univariate and multivariable regression analyses showed that lower education (≤10 years) was associated with increased risk of depressive symptoms. This study shows a high prevalence of depressive symptoms among seronegative controls and HIV-infected Cameroonians. Integrating care for mental disorders such as depression into primary health care and existing HIV/AIDS treatment programs in Cameroon may improve the wellbeing of the general population and could lower the HIV/AIDS burden.

Abstract
BACKGROUND We aimed to assess the high-risk group for suicide using different classification methods includinglogistic regression (LR), decision tree (DT), artificial neural network (ANN), and support vector machine (SVM). METHODS We used the dataset of a study conducted to predict risk factors of completed suicide in Hamadan Province, the west of Iran, in 2010. To evaluate the high-risk groups for suicide, LR, SVM, DT and ANN were performed. The applied methods were compared using sensitivity, specificity, positive predicted value, negative predicted value, accuracy and the area under curve. Cochran-Q test was implied to check differences in proportion among methods. To assess the association between the observed and predicted values, Ø coefficient, contingency coefficient, and Kendall tau-b were calculated. RESULTS Gender, age, and job were the most important risk factors for fatal suicide attempts in common for four methods. SVM method showed the highest accuracy 0.68 and 0.67 for training and testing sample, respectively. However, this method resulted in the highest specificity (0.67 for training and 0.68 for testing sample) and the highest sensitivity for training sample (0.85), but the lowest sensitivity for the testing sample (0.53). Cochran-Q test resulted in differences between proportions in different methods (P<0.001). The association of SVM predictions and observed values, Ø coefficient, contingency coefficient, and Kendall tau-b were 0.239, 0.232 and 0.239, respectively. CONCLUSION SVM had the best performance to classify fatal suicide attempts comparing to DT, LR and ANN.

Abstract
BACKGROUND Since suicide attempt among adolescents is a major challenge and the reasons why this age group attempt suicide are complex, the aim of this study was to investigate the risk factors that contribute to suicide attempt among adolescents. MATERIALS AND METHODS In this qualitative content analysis, 14 adolescents (12-19 years old) who were admitted in two hospitals in Shiraz, Iran, were interviewed. Participants who tried attempt suicide with medication were selected by purposive sampling and the data were gathered by semi-structured interviews. Data analysis was guided by the conventional approach of qualitative content analysis. RESULTS Three major themes and 13 subthemes emerged from data analysis. The main themes were: (a) Individual factors and experiences (psycho-emotional problems, puberty, religious beliefs, stress management strategies, marriage and love, field and level of education); (b) family factors (family structure, family relationship, family economic features, family health conditions); and (c) social factors (suicidal behavior in others, media influence, professional support). CONCLUSIONS This study identified three major themes related to suicide attempt among adolescents in the context. As a result, suicide prevention and care provision should formulate a comprehensive method, considering the interaction of medical besides individual, familiar, and social factors in their assessment and care provision.

Abstract
BACKGROUND Suicide remains a significant public health problem worldwide. The aim of this study was to assess the mortality trend of suicide in Serbia for the years 1991-2014. METHODS Data on persons who died of suicide and self-inflicted injury (site codes E950-E959 revision 9 and X60-X84 revision 10 of the International Classification of Diseases to classify death, injury and cause of death) were obtained from the Statistical Office of the Republic of Serbia. The age standardized rate was calculated by direct method (per 100,000 persons, using Segi's World population as standard population). Average annual percentage change (AAPC) with the corresponding 95% confidence interval (CI) was computed for trend using the joinpoint regression analysis. RESULTS Total 33,930 (24,016 men and 9914 women) suicide deaths occurred in Serbia during the observed period, with the average annual age-standardized mortality rate being 12.7 per 100,000 inhabitants (19.5 per 100,000 in men and 6.7 per 100,000 in women). Suicide mortality in all age groups was higher among men than women. In both genders, suicide rates were highest in the oldest age group. Significantly decreased trend in suicide mortality was recorded continuously from 1991 to 2014 (AAPC=-1.9%, 95%CI -2.2 to -1.6). The most frequently used suicide method in both genders was hanging, strangulation or suffocation with 61.2% off all suicides. Changes in mortality rates were significant both for suicide by firearms, air guns and explosives (AAPC=-1.5% (AAPC=-1.5% in men and -3.1%-3.1% in women) and for suicide by hanging, strangulation, and suffocation (AAPC=-1.2% (AAPC=-1.2% in men and -3.0%-3.0% in women). In men, nonsignificant increase in suicide by firearms, air guns and explosives observed during the period 1991-1997 (by +6.1% per year) was followed by a significant decrease until 2014 (by -3.1% per year). The significantly increased mortality in suicide by firearms, air guns, and explosives was observed in older men (aged 40-69 years and 80 years and over). LIMITATIONS The low rate of autopsies in Serbia, as well as the accuracy, reliability and comparability of the suicide mortality data is always a question. CONCLUSIONS Downward trend in suicide mortality occurred in Serbia in last two decades. However, suicide rates are still very high in Serbia compared with the rates of suicides in developed countries. Particularly worrisome is the increase in mortality in older men, especially due to firearm suicides, air rifles, and explosives. Thus, additional efforts in the prevention of suicide are very important.

Abstract
Background This study aimed to illustrate the characteristics of suicide attempters treated in the Emergency Departments of 7 general hospitals in Xi’an and to provide relevant data for early psychological treatment. Material/Methods Between October 2010 and September 2014, 155 suicide attempters were treated in the Emergency Departments. Data were collected using a semi-structured questionnaire. Descriptive statistics, chi-square tests, and multivariate analyses were used to identify the factors associated with suicidal behaviors. Results Females outnumbered males at a ratio of 3.7 to 1. The greatest proportion of cases was in the age group of 21 to 30 years (52.9%). Patients who finished middle school or high school accounted for most of the suicide attempters (50.3%). The most common method used for attempted suicide was drug ingestion (86.5%). The majority of cases attempted suicide at home (74.8%) during the night. Marriage frustration, work and study problems, family fanaticism and conflict, somatic disease, and history of mental disorders were all significantly associated with suicide attempts. The ratio of patients to be discharged or to die were similar in occupation, marital status, and the place of suicide attempt; however, the results were different in gender, age, educational level, methods used for suicide, time of day, and reason. Conclusions Suicide is an important public health problem and is multidimensional in nature. Future studies with larger samples are expected to provide more specific knowledge of the effect of each social factor on the suicide risk in Chinese in order to improve the prevention of suicides.

Abstract
BACKGROUND Suicide is an act of intentionally causing one's own death. Number of suicidal incidences is proportional to attempted suicide cases hence if attempt cases are reduced, number of suicidal death can also be decreased and for that purpose risk factors should be identified and reduced. Therefore, this study is planned to identify risk factors among lower socioeconomic rural population of surrounding areas of Hyderabad in India. MATERIALS AND METHODS This was a prospective study in which all the suicide attempt cases reported at Bhaskar Medical College and General Hospital were included. The study period was from January 2013 to July 2013. They were undergone a detailed psychiatric interview, including their demographic details, and complete suicide risk assessment was done using Beck's suicide intent scale. RESULTS It was found that females in the age group of 20-30 years, uneducated, married and daily laborers by occupation had higher incidence of suicidal attempts. Depressive disorder is the most common associated psychiatric disorder in both the genders, followed by alcohol use related problems. Family disputes are the other major risk factors. Most common mode for attempt was organophosphorous poisoning followed by ingestion of calotropis. CONCLUSION Risk of suicide attempt is almost equal in terms of medium and high category of suicide assessment scale in both genders. We suggest that all individuals with alcohol related disorders must be screened for suicidal ideation so that appropriate methods can be adopted to reduce the risk.

Abstract
BACKGROUND Intent in attempted suicide is considered an indicator of subsequent suicide. Few studies in developing countries have examined correlates of suicidal intent among young adults. AIMS This study aimed to assess the intent score among a sample of young suicide attempters from South India and to identify the factors associated with suicide intent among them. METHOD The clinical charts of 64 consecutive subjects aged 15-24 years attending emergency services for attempted suicide were reviewed. All participants completed a semistructured proforma, the Presumptive Stressful Life Events Scale, the Beck Hopelessness Scale, the Pierce Suicide Intent Scale, and the Global Assessment of Functioning Scale. Psychiatric diagnoses were made according to the ICD-10 clinical descriptions and diagnostic guidelines. RESULTS The intent scores were in the moderate-to-high range for most subjects. Suicide intent score significantly varied depending on the presence or absence of psychiatric morbidity. In bivariate analysis, psychiatric morbidity and hopelessness correlated positively with suicide intent, and in linear regression, hopelessness emerged as a predictor of suicide intent. CONCLUSION A high intent of suicide in young is associated with psychiatric morbidity and presence of hopelessness. Hopelessness may be a key predictor of suicidal intent. Assessment of suicidal intent and hopelessness among young attempters is important and may help identify high-risk individuals who need intensive interventions.

Abstract
BACKGROUND Suicide, a social phenomenon, is a major health problem in most countries. Yet data relating to the role social factors play in the development of this condition are lacking, with some factors shrouded in greater ambiguity than others. As such, this review aimed to determine the prevalence of social-related factors resulting in suicide and to present these findings through meta-analyses, allowing for causes of heterogeneity to be examined. METHODS Scientific databases including PubMed and Science direct were searched using sensitive keywords. Two researchers reviewed the eligibility of studies and extracted data. Meta-regression with the Mantel-Haenszel method was conducted using a random effect model, in addition to subgroup analysis and Egger's test. RESULTS A total of 2,526 articles were retrieved through the initial search strategy, producing 20 studies from 16 provinces for analysis. The most frequent cause of attempted suicide among the 20 analyzed articles was family conflict with 32% (95% CI: 26-38). Other related factors included marital problems (26%; 95% CI: 20-33), economic constrains (12%; 95% CI: 8-15) and educational failures (5%; 95% CI: 3-8). Results of meta-regression analysis found that sample size significantly affects heterogeneity for the factor 'family conflict'. CONCLUSIONS Social factors such as family conflicts and marital problems have a noticeable role in Iranian suicidology.

Abstract
BACKGROUND Reports on suicide from the Gulf region are scarce. Dubai is a city with a large expatriate population. However, total and gender-specific suicide rates for the national and expatriate populations are not known. AIMS To investigate total and gender-specific suicide rates in the national and expatriate population in Dubai and to elicit socio-demographic characteristics of suicide victims. METHODS Registered suicides in Dubai from 2003 to 2009, and aggregated socio-demographic data of suicide victims were analysed. Suicide rates per 100,000 population were calculated. RESULTS Suicide rate among expatriates (6.3/100,000) was seven times higher than the rate among the nationals (0.9/100,000). In both groups, male suicide rate was more than three times higher than the female rate. Approximately three out of four expatriate suicides were committed by Indians. The majority of suicide victims were male, older than 30 years, expatriate, single and employed, with an education of secondary school level and below. CONCLUSION Further research on risk factors for and protective factors against suicide, particularly among the expatriate population, is needed. Epidemiological monitoring of suicide trends at the national level and improvement of UAE suicide statistics would provide useful information for developing suicide prevention strategies.

Abstract
BACKGROUND Epidemiologic studies have reported conflicting results relating smoking to suicide risk. We conducted a meta-analysis of prospective cohort studies to evaluate the association of cigarette smoking with completed suicide. METHODS Eligible prospective cohort studies were identified from PubMed and EMbase databases (from 1966 to May 2011) and the reference lists of retrieved articles. Two authors independently extracted data and assessed study quality using the Newcastle-Ottawa Scale. Study-specific risk estimates were pooled using random-effects model and generalized least squares trend estimation was used to assess dose-response relationship. RESULTS Fifteen prospective cohort studies involving 2395 cases among 1,369,807 participants were included in the meta-analysis. Our data suggested that cigarette smoking significantly increased the risk of completed suicide. Compared with never smokers, the pooled RR was 1.28 (95% CI: 1.001-1.641) for former smokers, and 1.81 (95% CI: 1.50-2.19) for current smokers, respectively. Subgroup analyses showed that the increased suicide risk among current smokers appeared to be consistent, although there was heterogeneity among studies of current smoking (p < 0.001). Significant dose-response relationship was found between smoking and suicide, and the risk of suicide was increased by 24% for each increment of 10 cigarettes smoked per day (RR, 1.24; 95% CI: 1.20-1.28). CONCLUSIONS Our meta-analysis robustly demonstrates that cigarette smoking is associated with an increased risk of completed suicide, consistent with a dose-response relationship. This conclusion has an important public health message for countries with high smoking prevalence and high suicide rate such as China.
