Suicide attempts during heavy drinking episodes among individuals entering alcohol treatment in Warsaw, Poland

The association between alcohol use and suicide attempt in employees

Purpose: This study aimed to analyze the alcohol use patterns that may influence suicide attempt in employees who have suicidal ideation.Methods: The 15,199 participants were classified into three groups according to suicide risk severity. Participant scores on the Alcohol Use Disorders Identification Test-Korea (AUDIT-K), subscale for drinking amount/frequency (AUDIT-C, items 1–3), subscale for dependence/related problems (AUDIT-D/P, items 4–10), and other sociodemographic and psychiatric scales were analyzed between the groups using one-way analysis of variance (ANOVA) and the chi-square test, followed by post hoc analysis using the Bonferroni correction.Results: A statistically significant difference between all three groups was observed for AUDIT-D/P scores after post hoc analysis (P < 0.001), indicating an increasing trend for greater suicide risk. This trend was present in both sexes and across all age groups above 30 years old.Conclusion: Alcohol dependence/related problems are significantly associated with suicide attempt among employees. Assessing and preventing suicide risk according to these issues may minimize socioeconomic losses due to suicide.

Alcohol Consumption and Violent Deaths in the City of Sao Paulo in 2015

Background: Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control, making people more vulnerable to violence and accidents, with thus a potential association between alcohol consumption and violent deaths. Objective: To assess the association between alcohol consumption and violent deaths in the city of Sao Paulo, Brazil, in 2015, and its relationship with gender, age, cause of death and blood alcohol concentration (BAC) of victims. Methods: A cross-sectional retrospective study was conducted by collection of data from 2,882 victims of violent deaths subjected to examination of BAC from the archives of the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Results: Alcohol was detected in blood samples of 27.06% of the victims and mean BAC levels were 1.92 ± 1.24 g/L. The mean age of the victims was 33.49 ± 15.19 years. The majority of the victims were male (84.14%) and the prevalence of positive BAC was higher amongst men (28.74%) than women (18.16%). Homicide was the most prevalent cause of death in the sample (36.57%), but there were a higher proportion of traffic accidents victims with positive BAC (32.01%), as well as higher BAC levels in these victims (46.77% in the range of 1.6-2.5 g/L). Conclusions: The results obtained in this study support a potential association between alcohol consumption and violent deaths in the city of Sao Paulo, mainly in traffic accidents victims.

A preliminary examination of the association between drinking as a typical coping strategy and level of acute alcohol consumption prior to a suicide attempt

Drinking to cope is associated with suicide ideation and attempts. Event-based research shows drinking, particularly when alcohol is consumed in large quantities, increases the intensity of suicidal thoughts and immediate risk for attempt. Such findings suggest those who typically drink to cope may be especially likely to drink heavily in the hours preceding a suicide attempt. In the first examination of the association between regular use of alcohol as a coping strategy and acute alcohol consumption prior to a suicide attempt, participants included 130 patients hospitalized for a recent attempt. The number of drinks consumed in the acute period preceding the attempt, as well as past-year heavy drinking frequency, typical drinking motives, and depressive symptoms were assessed. The unique impacts of coping motives on odds of consuming any alcohol, and of using specific amounts of alcohol in the acute period, were determined through binary and multinomial logistic regressions. Results demonstrated that commonly drinking for coping motives increased the odds of heavy drinking - but not of using alcohol at low levels - during the acute period. Results held after adjusting for relevant covariates. Clinicians should assess drinking motives and prioritize prevention of drinking to cope to reduce risk of alcohol-related suicide attempts.

Identifying alcohol problems among suicide attempters visiting the emergency department

BACKGROUND

Many suicide attempters brought to our emergency department (ED) have been found to have alcohol problems, and this should be taken serious consideration because alcohol use disorder is a risk factor for suicide reattempt. In this study, we aimed to estimate the effectiveness of alcohol-related biochemical markers and Alcohol Use Disorder Identification Test Consumption (AUDIT-C) in suicide attempters who visited our ED based on the gold standard for clinical diagnosis used by psychiatrists for alcohol use disorder. Moreover, we aimed to search for a significant standard when clinicians make correct predictions about alcohol use disorder using these markers.

METHODS

Among the subjects who visited ED following a suicide attempt, a total of 203 subjects were selected. Following a psychiatric interview, the subjects who met the criteria for alcohol abuse or alcohol dependence according to DSM-IV-TR in the past year were defined as the "alcohol use disorder" group. Although some subjects did not meet these criteria, men with a weekly alcohol intake of ≥14 drinks and women with a weekly alcohol intake of ≥7 drinks were classified as the "risky drinking" group. AUDIT-C was used as a self-report; further, aspartate aminotransferase, gamma-glutamyltransferase (GGT), and carbohydrate-deficient transferrin (CDT) were assayed using standard methods, and GGT-CDT was calculated using this formula: 0.8 × ln(GGT) + 1.3 × ln(%CDT).

RESULTS

In total, 88 subjects met the criteria for alcohol use disorder and 115 were included in the reference group. In the screening for alcohol use disorder, the AUC of AUDIT-C was 0.89 for men and 0.87 for women. In the screening for risky drinking, the AUC of AUDIT-C was 0.99 for men and 0.93 for women. Compared with other biochemical markers, AUDIT-C showed the highest AUC value for screening for both alcohol use disorder and risky drinking, with the trend being more prominent in men.

CONCLUSIONS

Among the biochemical markers, AUDIT-C yielded the highest sensitivity, specificity, and accuracy in diagnosing alcohol use disorder among suicide attempters in ED. Comparison of results revealed that the use of AUDIT-C with biochemical markers or its use alone can help screen for alcohol use disorder or risky drinking in clinical settings.

Demographic and Clinical Characteristics of Completed Suicides in Mexico City 2014-2015

Objective: To analyze sex differences in demographic and clinical characteristics of individuals who died by suicide in Mexico City. Method: Statistical analysis of residents of Mexico City whose cause of death was suicide, during two years period from January 2014 to December 2015, with a coroner's report. Suicide mortality rates were calculated by age, sex, and location within the city. The Chi-squared test was used to assess statistical differences. Results: From January 2014 to December 2015, 990 residents of Mexico City died by suicide (men: 78.28%, women: 21.72%). Among males, the highest mortality rates were among the groups of 20-24 and 75-79 years old, whereas in women, the group with the highest mortality rate was 15 to 19 years old. 74% of the sample used hanging as suicide method. However, men had higher rates of a positive result in the toxicology test (40%) (p < 0.05). There was no concordance between male and female suicide by city jurisdictions. Conclusion: Our results provide evidence that the characteristics of Mexico City's residents who committed suicide had significant sex-related differences, including where they used to live. Understanding the contributory factors associated with completed suicide is essential for the development of effective preventive strategies.

Alcohol use by suicide victims in the city of Sao Paulo, Brazil, 2011-2015

Excessive alcohol consumption is a serious public health issue, because drunkenness affects critical judgment and self-control which could trigger violent and self-harm behavior, with thus a potential association between alcohol consumption and suicide deaths. The objective of the present study was to assess the association between alcohol consumption and suicide deaths in the city of Sao Paulo, Brazil, from 2011 to 2015, and its relationship with socio-demographic characteristics of the victims and the circumstances of the suicide. A cross-sectional retrospective study was conducted by collection of data from 1,700 suicide victims subjected to examination of blood alcohol concentration (BAC) from toxicology reports from the Institute of Legal Medicine of the State of Sao Paulo, Brazil. Alcohol was detected in blood samples of 30.2% of the victims and mean BAC levels were 1.73 ± 0.08 g/L. The mean age of the victims was 39.90 ± 0.75 years. The majority of the victims were male (74.6%) and the prevalence of positive BAC was higher amongst men (34.7%) than women (17.1%), p<0.05. The majority of the victims were white skinned (64.7%), but there was a higher proportion of victims with positive BAC among mulatto and black individuals, p<0.05. Hanging was the most prevalent suicide method in the sample (48.7%) and amongst men (55.4%), but amongst women it was jumping from a height (35%), p < 0.05.

Impact of acute alcohol consumption on lethality of suicide methods

BACKGROUND

The influence of acute alcohol consumption on the factors related to suicide remains understudied. Thus, the present study investigated the relationship between blood alcohol content (BAC) and the lethality of suicide methods.

METHODS

Autopsy data on 315 South Korean suicide completers with a positive BAC were collected from a nationwide pool between May 2015 and November 2015, and the methods were dichotomised as suicide methods of low lethality (SMLL; drug/chemical overdose and sharp objects, n=67) and suicide methods of high lethality (SMHL; everything else, n=243). BAC at the time of autopsy and various suicide-related factors of these two groups were compared with logistic regression analyses.

RESULTS

Compared to suicide completers with a BAC in the lowest range of 0.011-0.049%, suicide completers with a BAC in the range of 0.150-0.199% were more likely to use SMHL (odds ratio [OR]: 3.644, 95% confidence interval [CI]: 1.221-10.874). Additionally, the adoption of SMHL was significantly associated with the absence of a psychiatric illness (OR: 0.433, 95% CI: 0.222-0.843) and a younger age; the OR for high BAC among subjects in their 40s was 0.266 (95% CI: 0.083-0.856); in their 50s, 0.183 (95% CI: 0.055-0.615); and in their 60s, 0.057 (95% CI: 0.015-0.216).

CONCLUSIONS

The relationship between BAC and suicide method lethality was represented by a bell-shaped pattern in which suicide methods of high lethality were more likely to be used by suicide completers with mid-range BAC levels. The increased impulsivity and impairments in particular executive functions, including planning and organization, associated with acute alcohol use may influence the selection of a particular suicide method based on its lethality.

Role of Demographic and Personality Factors in Mediating Vulnerability to Suicide Attempts under Intoxication with Alcohol: A Record-based Exploratory Study

BACKGROUND

Identifying those who are likely to make suicide attempts under alcohol intoxication has important implications for management and prevention of further suicidal behavior.

AIMS

To identify the frequency of suicide attempts made under the influence of alcohol and the percentage of impulsive suicide attempts among them. We also aimed to identify predictors of attempted suicide under intoxication with alcohol.

SETTING AND DESIGN

Record-based study carried out at a tertiary care hospital.

MATERIALS AND METHODS

The clinical charts of consecutive suicide attempters (n = 147) who presented to the crisis intervention clinic from July 2013 to June 2014 were reviewed, and relevant data were extracted. The participants were divided into three groups - nonusers of alcohol (n = 85), alcohol users who did not attempt under intoxication (n = 31) and alcohol users who attempted under intoxication (n = 31). These groups were compared on various sociodemographic and clinical variables. Logistic regression was done to identify predictors of suicide attempt under intoxication.

STATISTICAL ANALYSIS USED

Chi-square (χ²) test, one-way ANOVA (F) test and backward stepwise logistic regression.

RESULTS

About 21.08% of all suicide attempts occurred under alcohol intoxication. Such subjects were more likely to be older (F = 12.428, P < 0.001), male (χ² = 87.367, P < 0.001), married (χ² = 6.787, P = 0.034), employed (χ² = 41.778, P < 0.001), and fewer years of formal schooling (F = 3.312, P = 0.039). Physical methods (hanging) were used more often in this group (χ² = 19.510, P = 0.012). In regression analysis, only marital status and living condition emerged as predictors of attempt under intoxication (odds ratios 4.52 [confidence interval (CI) 1.34-15.24, P = 0.015] and 5.67 [CI 1.17-27.39, P = 0.031] respectively).

CONCLUSION

Certain demographic features may help us in identifying those who are more likely to make attempts under intoxication. The role of personality factors as potential mediators of such behavior needs further exploration.

From impulse to action among military personnel hospitalized for suicide risk: alcohol consumption and the reported transition from suicidal thought to behavior

OBJECTIVE

Alcohol use is associated with unplanned or impulsive suicide attempts. Although unplanned suicide attempts assume a rapid transition for suicidal impulse to action, many studies do not quantify the time elapsed from suicidal impulse to action. The current study was designed to clarify how alcohol use facilitates the transition from suicidal impulse to action among U.S. Army personnel. We hypothesized that alcohol consumption during the 24 h preceding a suicide attempt would be associated with significantly faster transition from suicidal impulse to action but would be unrelated to medical lethality.

METHOD

A total of 119 active duty U.S. Army Soldiers who made a total of 175 suicide attempts during military service, 121 of which occurred during the preceding year, completed clinician-administered structured interviews focused on psychiatric diagnosis and the contextual characteristics of their suicide attempts.

RESULTS

Alcohol use during the 24 h prior to a suicide attempt was associated with significantly faster transition from suicidal impulse to action. Among suicide attempts in the past year, lethality significantly increased as the length of time since the last alcoholic drink increased. Drug use during the 24 h prior to a suicide attempt was unrelated to speed of transition or attempt lethality.

CONCLUSIONS

Soldiers acted upon their suicidal impulses more quickly when they had been drinking on the day of their suicide attempts. This rapid transition may contribute to the selection of less lethal suicide methods during periods of active drinking as compared to methods selected after the discontinuation of alcohol consumption.

PTSD, Depression, and Substance Use in Relation to Suicidality Risk among Traumatized Minority Lesbian, Gay, and Bisexual Youth

Youths who are lesbian, gay, or bisexual (LGB) are more likely than heterosexuals to commit suicide. Substance use, PTSD, and depression are independent risk factors for suicidality; however, the extent to which these factors interact to predict suicidality is unclear. The current study examined the association between substance use, PTSD symptoms (PTSS), depressive symptoms, and suicidality in a sample of 68 traumatized minority LGB youths. Participants were recruited from an LGBT community center and completed a packet of questionnaires. Substance use and depressive symptoms were positively associated with prior suicide attempts. A significant three-way interaction revealed that substance use interacted with both PTSS and depressive symptoms to increase the odds of attempted suicide. Results underscore the importance of integrating substance use components into PTSD/depression treatment to reduce suicide risk in LGB youth.

Interpersonal violence, alcohol use, and acquired capability for suicide

Acquired capability for suicide (ACS), defined as pain tolerance and fearlessness about death, is theorized as necessary to enact suicide. This study examined the associations of interpersonal violence and alcohol use with ACS in 502 college students. General fearlessness/pain tolerance was positively associated with male gender and alcohol use. Fearlessness about death was positively associated with male gender and general physical violence perpetration. However, these risk factors did not explain variance in ACS beyond male gender and history of suicide attempts/nonsuicidal self-injury. These findings add to the understanding of ACS correlates.

Understanding PTSD comorbidity and suicidal behavior: associations among histories of alcohol dependence, major depressive disorder, and suicidal ideation and attempts

Individuals with posttraumatic stress disorder (PTSD) are at an elevated risk for experiencing suicidal thoughts and actions. However, a relative dearth of research has examined factors that may impact this relation, such as common co-occurring disorders. Utilizing the National Comorbidity Survey-Replication data, the current study examined comparisons between comorbid PTSD and major depressive disorder (MDD) and comorbid PTSD and alcohol dependence (AD) in relation to suicidal ideation and suicide attempts. It was hypothesized that comorbid MDD would be associated with an elevated likelihood of suicidal ideation, while comorbid AD would be associated with an elevated likelihood of suicide attempt history. Results indicated that only PTSD-AD was significantly associated with an elevated likelihood of endorsing histories of both suicidal ideation and suicide attempts. These findings suggest that AD may be a critical risk factor for acquiring the capability for suicide attempts.

Toxicology findings in suicides: concentrations of ethanol and other drugs in femoral blood in victims of hanging and poisoning in relation to age and gender of the deceased

Over-consumption of alcohol and/or abuse of other drugs are closely linked to attempted or completed suicides. In this retrospective 10-year study (2001-2010), we compared the toxicology findings in hanging suicides (n = 4551) with drug poisoning (intoxication) suicides (n = 2468). The mean age of hanging deaths was 49 ± 19 y (±SD) and 80% were male, compared with a mean age of 52 ± 17 y and 47% males for the intoxication deaths. Poly-drug use was more common in poisoning suicides with an average of 3.6 drugs/case compared with 1.8 drugs/case in hangings. Moreover, 31% of hangings were negative for alcohol and/or drugs. Alcohol was detected (>0.20 g/L) in femoral blood in 30% of hanging suicides (mean 1.39 g/L) and 36% of drug poisonings (mean 1.39 g/L). The median BACs did not depend on the person's age or gender (p > 0.05). Ethanol, paracetamol, citalopram, diazepam, propiomazine, alimemazine and zopiclone were amongst the top-ten drugs detected in both methods of suicide. With the exception of ethanol, the concentrations of drugs in blood were considerably higher in the poisoning deaths, as might be expected. Regardless of the method of suicide, antidepressants and/or antipsychotics were common findings, which could implicate mental health as a significant suicide risk factor.

Blood alcohol concentration and self-reported alcohol ingestion in acute poisoned patients who visited an emergency department

Background

Many acute poisoned patients have co-ingested alcohol in the emergency department (ED). This study aimed to estimate the blood alcohol concentration (BAC) of acute poisoned patients who visited an ED by age and gender distribution and to determine whether it is possible to obtain self-reports of alcohol ingestion among poisoned patients.

Method

A retrospective medical chart review was conducted for all patients who visited the ED with acute poisoning between January 2004 and February 2008. Data regarding the patient’s age, gender, BAC, self-reported alcohol ingestion, poison ingested, time elapsed since poison exposure, presence of suicide attempts, and self-reported alcohol ingestion were collected. Patients were classified into two groups based on serum alcohol levels (≤10 mg/dl, >10 mg/dl).

Results

Of the 255 subjects, 88 subjects (34.5%) were included in the non-alcohol group and 167 subjects (65.5%) were included in the alcohol group. 227 subjects (89.0%) showed suicide intention. Using the 201 subjects who completed the self-report of alcohol ingestion, self-report resulted in 96.6% sensitivity and 86.7% specificity for the assessment of alcohol ingestion. The positive and negative predictive values for self-report were 91.2% and 94.7%, respectively. The median (interquartile range) BAC of the 97 males in the sample was 85.0 (10.0-173.5) mg/dl, and that of the 158 females was 32.0 (4.0-137.5) mg/dl (p = 0.010). The distribution of age in the groups was significantly different between the alcohol and non-alcohol groups (p = 0.035), and there was a significant difference in the mean BAC with respect to age for males (p = 0.003).

Conclusion

This study showed that over two-thirds of patients presenting with acute poisoning had a BAC > 10 mg/dl. Most of patients visited by suicide attempt. Males had a higher BAC than did females. Self-reported alcohol ingestion in acute poisoned patients showed high sensitivity and specificity.
