“…Yamada et al reported that 95% and 65% of suicide attempters had mental disorders and were under psychiatric treatment, respectively [3]. In the present study, 94.3% of the subjects had mental disorders and 67.9% were under psychiatric treatment, percentages similar to those of the previous study.…”

BackgroundThere is a shortage of empirical data concerning precipitating factors for suicides in Japan. The purpose of the present study was to clarify gender differences of precipitating factors for suicide attempts in Japan.MethodsThe subjects were high-lethality suicide attempters who were admitted to the Nippon Medical School Hospital Critical Care Medical Center between March 1, 2010 and March 31, 2012. Precipitating factors for suicide attempt, method of suicide attempt, psychiatric diagnoses and other sociodemographic data were collected from the patients’ medical records retrospectively, and statistical analyses were performed for categorical variables of male/female.ResultsThe total number of subjects was 193 (88 males and 105 females). The rate of subjects attempting suicide by poisonous gas was significantly higher in males while that of subjects attempting suicide by drug overdose was significantly higher in females. The rate of subjects diagnosed with “major depressive disorder, bipolar disorder” was significantly higher in males while that of subjects diagnosed with “personality disorders” or “dysthymic disorder” was significantly higher in females. Subjects with “health problems”, “financial problems”, “work problems”, “debts (others)” or “unwanted transfer” were significantly more numerous among males; subjects with “family problems”, “parent–child relations” or “loneliness” were significantly more frequently found among females.ConclusionsMental disorders were the most common precipitating factor for suicide attempts regardless of gender. Significant gender differences were observed in psychiatric diagnoses, methods of suicide attempt and psychosocial problems. This indicates the necessity of suicide prevention measures corresponding to these gender differences.

“…These findings are compatible with those reported by other studies (Welch 2001; Maselko and Patel 2008; Ono et al 2008; Borges et al 2010; Mandour 2012; Patel et al 2012). It has been well reported that incidence of suicide among patients with psychiatric disorders is increased by up to 5–40 times, each completed suicide case corresponds to 6–25 repeated suicide attempts (Maris 2002; Yamada et al 2007). In a prospective follow-up study by Christiansen and Jensen (2007), the risk of repetition of suicide attempts in patients with a prior history of suicide attempt was increased 37.34 %, and mortality was increased four-fold, compared to other groups.…”

Aim Attempted suicide is one of the most important public health problems among preventable causes of mortality in the general population. Identifying risk factors for the prevention of suicide is a major public health goal. The aim of this study was to determine the annual rate of attempted suicide, related risk factors, and interventions, among referrals to emergency departments in the Sanliurfa province of southeastern Turkey. Subjects and methods Data were obtained from all emergency departments in the province based on the ‘Suicide Attempt Registry’ standardized records for the calendar year 2010. Sociodemographic characteristics, aetiology, psychiatric history, psychiatric consultations, and interventions were examined. The groups were analysed with the chi-square test; the significance level was set at p<0.05. Results The annual rate of suicide attempts was 55.39 in 100,000 for the calendar year 2010. The rate was 3.47 times higher among women than men, and in particular 4.15 times higher for the 15–24 year age group among women than in men with the highest incidence of suicide attempts. The majority of cases were referred in April and May. Medication or toxic agent ingestions comprised 90.3 % of cases. The main reason for attempts was family problems or domestic violence among women, and economic hardships among men, and rates of physical and mental problems were similar for both sexes. Only 8.8 % of cases were subsequently referred for psychiatric consultation. Among cases with a prior suicide attempt history, 44.6 % had a reported psychiatric disorder. Conclusion The results of this investigation show that strengthening of surveillance and emergency healthcare systems, enhancement of mental health literacy, and inter-sector collaboration for development of community empowerment programmes are of vital importance for prevention of attempted suicide. The low rate of psychiatric referrals for subsequent intervention represented a major gap in urgent mental health services in the region.

“…The methods of suicide attempt were extracted from the patient's record, and divided into violent and nonviolent attempts according to the operational criteria of Yamada et al [24] and subsequently analyzed. The violent suicide group was defined as follows: (1) mechanical ventilation was required for life support; (2) surgery was performed under general anesthesia; (3) the method of attempted suicide carried a high risk of death, specifically, hanging, gunshot, jumping from a high place, inhalation of gas, solvents, or other agricultural chemicals, thermal injury, or drowning.…”

Background: Some reports have suggested the involvement of the D₂ dopaminergic function in the expression of suicidal behavior. Here, we examined associations between suicide attempts and two kinds of functional polymorphisms in the dopamine D₂ receptor (DRD2) gene, namely, TaqIA and –141C Ins/Del. Methods: Subjects included 120 suicide attempters and 123 unrelated volunteers. Those who attempted suicide were severely injured and were transferred to the emergency unit in our university hospital. To determine each genotype, we performed polymerase chain reaction and restriction fragment length polymorphism analyses. Results: We found significant differences in genotypic and allelic frequencies of –141C Ins/Del and TaqIA polymorphisms between suicide attempters and healthy controls (–141C Ins/Del, p = 0.01; TaqIA,p = 0.036). The Ins allele of –141C Ins/Del was significantly more frequent in suicide attempters (p = 0.011), as well as the A2 allele of TaqIA (p = 0.017). Haplotype analysis revealed no significant linkage disequilibrium between –141C Ins/Del and TaqIA polymorphisms (D′ = 0.226, r² = 0.016, p = 0.10). Conclusions: These findings suggest that DRD2 gene polymorphisms may be involved in the biological susceptibility to suicide.
