Acute use of alcohol before suicide in Kazakhstan: A population-wide study

Acute Alcohol Use and Suicide

Importance

While acute alcohol use (AAU) is known to increase the risk of suicide significantly, the underlying mechanisms of this association are still understudied.

Objective

To examine the association between AAU and the risk factors for suicide, focusing on the association between AAU and choice of suicide methods.

Design, Setting, and Participants

This cross-sectional study included data from the Korean National Investigations of Suicide Victims Study (KNIGHTS). The KNIGHTS dataset comprises nationally representative data encompassing nearly all suicide deaths in South Korea from January 1, 2013, to December 31, 2020. The study was analyzed from November 2 to 10, 2023.

Main Outcomes and Measures

The main outcome was whether decedents who died by suicide had consumed alcohol before their death. Trained investigators conducted psychological autopsies by reviewing police reports of suicide deaths. Whether the decedent who died by suicide had consumed alcohol before death was determined from 3 sources: (1) confirmation by informants, (2) autopsy reports indicating a positive blood alcohol concentration, and (3) observations from police officers. Demographic characteristics, premortem psychiatric symptoms, and suicide characteristics, including method of suicide and presumed reasons for suicide, were examined. Hierarchical logistic regression models were used to examine the association between the contributing factors and AAU.

Results

This study included 55 226 decedents who died by suicide (65.5% male), of whom 21 998 (39.8%) were under the influence of alcohol at the time of death. AAU was associated with being male (odds ratio [OR], 1.37 [95% CI, 1.31-1.44]); being middle aged (eg, from age 30 to 39 years: OR, 1.20 [95% CI, 1.06-1.35]); and having alcohol use disorder symptoms (OR, 13.28 [95% CI, 12.38-14.24]). Among suicide methods, gas, drug, and pesticide poisoning showed a positive association with AAU, with gas poisoning showing the highest OR (OR, 1.88 [95% CI, 1.61-2.20]). An interaction was found between age and suicide method, with older adults (eg, aged 80 years or older) having higher odds of AAU when using methods such as drug (OR, 6.28 [95% CI, 3.53-11.17]), pesticide (OR, 6.56 [95% CI, 3.86-11.13]), and gas (OR, 2.48 [95% CI, 1.52-4.04]) poisoning.

Conclusions and Relevance

The findings of this cross-sectional study suggest that AAU was associated with gas poisoning, as indicated by the ORs. Given that charcoal burning involves substantial preparation time, alcohol may have been deliberately used to facilitate planned suicide attempts. Furthermore, the deaths of older adults who consumed alcohol prior to suicide, even when using less lethal methods, highlight the critical need for monitoring and effectively managing alcohol use within this population.

Suicide victims and alcohol-related consumption in Brazil: An observational study and a narrative review of the literature

Deaths due to external causes, mainly suicide, are a severe public health problem in Brazil. Evidence shows that the tendency to impulsive behavior is exacerbated after alcohol consumption. The relationship between alcohol and suicide is poorly described in the medical literature. The study aims to analyze the relationship between victims' blood alcohol levels and suicides in some municipalities in Greater São Paulo, Brazil. We reviewed the data from the medical records of 805 necropsies performed at the Medical Legal Institute of Sao Paulo in Franco da Rocha, Brazil, from 2001 to 2017. The manner of death was established based on the result of police inquiry. Deaths due to suicide (n=41) were selected for the study. Descriptive statistics and Student t-test was applied when appropriate. The variables studied were sex, age, suicide mechanism, and blood alcohol level (BAC). In all cases we could not determine how much time the deceased consumed alcohol before suicide. Of the individuals analyzed, 85.36% were male, and 14.64% were female. The most prevalent age range for males was between 18 and 23 (19.5%). For females, it was between 12 and 23 years (33.2%). Most suicides (48.78%) were due to hanging, followed by self-poisoning (22.08%) and firearms (17.1%). 38 victims (92.68%) presented a positive BAC, over 0.3 mg/dl. The higher levels were in the group of suicide by hanging (2.3 mg/ml). Thus, alcohol intoxication is common among suicide victims, and it can contribute to the fatal outcome as a risk factor. Further studies are necessary for a better comprehension of the effect of alcohol on suicide victims.

Communication dynamics and media interactions of young adults who have attempted suicide: a qualitative thematic analysis

Objective

The study examines the potential effects of communication processes and media consumption habits on suicide ideation among male and female young adults aged 18-29 who have attempted suicide at least once.

Methods

In-depth interviews were analyzed using MAXQDA Analytics Pro 2024, and thematic analysis was applied according to Braun and Clarke's model.

Results

Four themes emerged: (1) Family-related factors, (2) sociopsychological factors, (3) sociocultural factors, and (4) media-related factors. Regarding family-related factors, most participants come from broken family structures and commonly report issues with family communication and experiences of violence. Regarding sociopsychological factors, anger issues, despair, and addictions among participants were observed to increase suicide tendencies. Regarding sociocultural factors, most participants expressed difficulties in conforming to society and feeling pressures from cultural or religious expectations. Regarding media-related factors, it was noted that a vast majority of participants spend long hours consuming media daily and frequently interact with content that leads them into adverse emotional states, primarily for time passing on social media platforms.

Discussion

This research not only reinforces information in the literature but also presents unique findings compared to similar studies, particularly in cultural and geographical contexts. The results uniquely highlight the diversity in perceptions of the relationship between religion and suicide. While literature generally notes religion as a deterrent to suicide, this study reveals that intense religious pressure could increase suicidal tendencies through effects like rejection and hatred of religious values. Media also plays a reinforcing role in this context.

Conclusion

In conclusion, this study elucidates the complex interactions underlying suicide attempts among young adults and provides a solid foundation for policies and interventions aimed at better managing media interactions, which play a critical role in suicide prevention efforts.

The relationship between a comprehensive index of prosperity and suicide rates in former Soviet countries, including a comparison with European and Asian countries: Discussion from a new perspective

Investigations of suicide in countries of the former Soviet Union, which broke into 15 different countries in the early 1990s, require examinations of a combination of economic, social, and health factors. It is important to address these factors individually and to examine the various composite indicators for each. Moreover, it would be worthwhile to explore the potential applicability of a comprehensive worldwide index. We analyzed data from nine of the former Soviet countries for which both the annual suicide rate and the Global Competitiveness Index (GCI) were available for the years 2006-2017. We determined the precise relationships between the suicide rate and the GCI during this period in these nine countries as well as in nine countries with high suicide rates in Europe and Asia. The results indicated the following: (i) In six of the nine former Soviet countries with complete data, the suicide rate showed a relationship with the GCI. Notably, this relationship was inverse in all but one country. (ii) Among the nine European and Asian countries with high suicide rates, three exhibited a correlation between the suicide rate and the GCI. Measures to prevent suicide should be devised especially in countries of the former Soviet Union through collaboration among multiple fields and organizations, as necessary, with particular attention paid to countries with worse or worsening GCI values.

Analyzing 14-years of suicide rates in Chile: Impact of alcohol policy, domestic violence, and a suicide prevention program

Suicide is a major public health problem worldwide with far-reaching effects on families, communities, and societies. Influencing factors range from macro-level interventions like alcohol control policies and suicide prevention programs to individual contributors such as alcohol abuse and domestic violence. This study aimed to examine the relationship between Chile's suicide rate changes from 2002 to 2015 and the Alcohol Act of 2004, a national suicide prevention program implemented in 2007, alcohol abuse, and domestic violence. Assembling a unique longitudinal dataset from Chilean public institutions, the study employed an instrumental variable time-series cross-regional design. Results indicated that the Alcohol Act was not associated with suicide rates, domestic violence exhibited a significant association with increased suicide rates, and the national suicide prevention program was linked to reductions in suicide rates, especially among males. These findings align with research from neighbouring countries, showcasing the efficacy of suicide prevention programs in decreasing suicide rates in Chile. Results highlight the importance of integrating protocols to early-detect domestic violence in suicide prevention programs, as well as the need to further improving alcohol control policies to complement suicide prevention programs.
