Do alcohol restrictions reduce suicide mortality?

AIM: Blood alcohol concentration (BAC) at the time of suicide was examined in relation to the marked falls in suicide rates and per capita alcohol consumption in Estonia during the major Soviet anti-alcohol campaign from 1 June 1985. DESIGN AND PARTICIPANTS: In all, 5054 suicide cases (76% males, 24% females) were examined with respect to the official autopsy reports of the Estonian Bureau of Forensic Medicine (autopsy rates: 95% of males, 88% of females) before (1981-84), during (1986-88) and after (1989-92) the campaign. Cases were divided by gender and BAC level (0.5-1.49, 1.5-2.49 and > 2.5 per thousand). FINDINGS: During the campaign, annual per capita alcohol consumption in Estonia fell from 10.9 to 6.6 l. Alcohol in blood was found in 47.9% before, 35.1% during and 40.9% after the campaign. During the intervention, BAC-positive, i.e. alcohol-positive, suicides decreased by 39.2% for males and 41.4% for females, with the largest fall occurring at the BAC 2.5 per thousand + level for both sexes. Changes in BAC-negative suicides were modest. When the campaign ended suicide rates started to rise. CONCLUSIONS: Investigation on an individual level showed that alcohol consumption was a common precursor to suicide and that rigorous alcohol restrictions were accompanied particularly by a decrease in BAC-positive suicide mortality among both sexes. However, the 'natural experiment' does not, in terms of study design, demonstrate convincingly that the fall in the suicide rate was due specifically to the decrease in alcohol use as such.

The role of alcohol in suicide: a case-control psychological autopsy study.

BACKGROUND: The purpose of the study was to estimate the proportion of alcohol abuse and dependence (AAD) among suicides and controls, and to compare the incidence of AAD documented by clinicians with diagnoses derived from a research protocol. METHOD: AAD according to DSM-IV was diagnosed on the basis of interviews with relatives of people who committed suicide and with controls. A total of 427 people who committed suicide during one year were paired by region, gender, age and nationality with controls randomly selected from general practitioners' lists. RESULTS: Alcohol abuse was found in 10% and alcohol dependence in 51% of suicide cases. The corresponding figures for controls were 7% and 14% respectively. AAD was a statistically significant predictor of completed suicides, while abstinence was a significant predictor for female suicides and former use a significant predictor for older male suicides. AAD was diagnosed in 68% of male and 29% of female suicides. Middle-aged (35-59 years) males who committed suicide had the highest risk of alcohol dependence. Among suicide cases only 29% had received a lifetime diagnosis of AAD, against 23% of controls. CONCLUSIONS: AAD was significantly more prevalent among suicides than controls. Overall, the proportion of male suicides affected by alcohol was the same in the present psychological autopsy study as in our previous findings for Estonia on the aggregate level, while the share of female suicides with an AAD diagnosis was dramatically higher on the individual level. AAD is markedly underdiagnosed by general practitioners and clinicians.

Recent life events and suicide: a case-control study in Tallinn and Frankfurt.

The purpose of this study was to analyze the differences in the disposition and frequency of recent life events preceding suicide in two cities with different socio-political backgrounds: Tallinn in Estonia and Frankfurt/Main in Germany. The information about 156 suicidents in Tallinn and 163 suicidents in Frankfurt was compiled using the psychological autopsy technique [Shneidman, E. S. (1981). The psychological autopsy. Suicide and Life-Threatening Behavior, 11, 325-340; Jacobs, D., & Klein-Benheim, M. (1995). The psychological autopsy: A useful tool for determining proximate causation in suicide cases. Bulletin of American Academy of Psychiatry Law, 23(2), 165-182]. General population controls were matched by age and sex. The occurrence of recent life events was similar among suicidents in Tallinn (81%) and Frankfurt (77%). However, in both sites only male suicides had higher risk of occurrence of any life event than controls (Tallinn: OR'=1.9; 95% CI=1.1-3.7; Frankfurt: OR'=2.0; 95% CI=1.0-4.1) and the mean number of life events was significantly higher among male suicidents in Tallinn in comparison with controls. This may indicate that males are more sensitive to the rapid changes in a society undergoing transition. It seems that it is not the number of life events, but rather their meaning and disposition that creates the risk of suicide. Family discord (weighted OR=4.5; 95% CI=2.5-8.1), loss of job (weighted OR=2.6; 95% CI=1.0-6.4) and financial deterioration (weighted OR=2.2; 95% CI=1.3-3.8) were more prevalent among suicides in Tallinn in comparison with those in Frankfurt. The most significant differences between suicides and controls were family discord, separation and loss of job in Tallinn and somatic illness in Frankfurt. These differences between the two societies, post-Soviet Estonia and Germany, could be explained by the different positions of Estonia and Germany on the survival/self-expression dimensions recorded by the World Value Survey. People in Estonia tend to emphasize economic and physical security above all other goals, and feel threatened by the changes taking place in society. In Germany, good health is considered a necessity for a consumer and self-expressive style of life, and poor health is perceived as a serious threat to the quality of life in a post-materialistic value system.

Factors predicting suicide among Russians in Estonia in comparison with Estonians: case-control study.

AIM: To explore differences between suicide victims among Russian immigrants in Estonia and native Estonians, according to socio-demographic background, substance use pattern, and recent life events to find out immigration-specific factors predicting suicide. METHODS: The psychological autopsy study included 427 people who committed suicide in 1999 and 427 randomly selected controls matched by region, gender, age, and nationality. RESULTS: The only variable that differed significantly between Russian and Estonian suicide cases was substance use pattern. Logistic regression models showed that factors associated with suicide for both nationalities were substance dependence and abuse (Russians: odds ratio [OR], 12.9; 95% confidence interval [95% CI], 4.2-39.2; Estonians: OR, 8.1; 95% CI, 3.9-16.4), economical inactivity (Russians: OR 5.5; 95% CI, 1.3-22.9; Estonians: OR, 3.1; 95% CI, 1.3-7.1), and recent family discord (Russians: OR, 3.2; 95% CI, 1.1-9.9; Estonians: OR, 4.5; 95%, CI, 2.1-9.8). The variables that remained significant in the final model were having no partner (Estonians: OR, 3.0; 95% CI, 1.6-5.5), being unemployed (Estonians: OR, 5.5; 95% CI, 2.0-15.4), and being an abstainer (Estonians: OR, 6.7; 95% CI, 2.5-17.6) for Estonians, and somatic illness (Russians: OR, 4.1; 95% CI, 1.4-11.7), separation (Russians: OR, 32.3; 95% CI, 2.9-364.1), and death of a close person (Russians: OR, 0.2; 95% CI, 0.04-0.7) for Russians. CONCLUSION: Although the predicting factors of suicide were similar among the Estonian Russians and Estonians, there were still some differences in the nature of recent life events. Higher suicide rate among Estonian Russians in 1999 could be at least partly attributable to their higher substance consumption.

Suicide attempts, plans, and ideation in culturally diverse sites: the WHO SUPRE-MISS community survey.

BACKGROUND: The objectives were to assess thoughts about suicide, plans to commit suicide and suicide attempts in the community, to investigate the use of health services following a suicide attempt, and to describe basic socio-cultural indices of the community. METHOD: The community survey was one component of the larger WHO multisite intervention study on suicidal behaviours (SUPRE-MISS). In each site, it aimed at randomly selecting and interviewing at least 500 subjects of the general population living in the catchment area of the emergency department where the intervention component of the study was conducted. Communities of eight SUPRE-MISS sites (in Brazil, China, Estonia, India, Iran, South Africa, Sri Lanka, and Viet Nam) participated plus two additional sites from Australia and Sweden conducting similar surveys. RESULTS: Suicide attempts (0.4-4.2%), plans (1.1-15.6%), and ideation (2.6-25.4%) varied by a factor of 10-14 across sites, but remained mostly within the ranges of previously published data. Depending on the site, the ratios between attempts, plans, and thoughts of suicide differed substantially. Medical attention following a suicide attempt varied between 22% and 88% of the attempts. CONCLUSIONS: The idea of the suicidal process as a continuous and smooth evolution from thoughts to plans and attempts of suicide needs to be further investigated as it seems to be dependent on the cultural setting. There are indications, that the burden of undetected attempted suicide is high in different cultures; an improved response from the health sector on how to identify and support these individuals is needed.

Internet comments on media reporting of two adolescents' collective suicide attempt.

The presented study covered the analysis of 7 Internet media portrayals and 188 readers' spontaneous Internet comments about a case of two adolescents who survived a serious suicide attempt. Articles with photographs attracted the most responses (82%), irrespective of the length and content of the articles. More than half of the comments expressed readers' negative attitude (ironic 31% and angry 28%) while 21% of them remained neutral or indifferent. Twenty one percent of readers tried to initiate a serious discussion about the causes and prevention of suicide. An association was found between the style of media reporting and the number of readers' comments as well as certain aspects of the content of the comments. Inadequate reporting of suicidal behavior is associated with comments expressing oversimplified attitudes towards suicide. The influence of suicide reporting on the Internet on attitude formation in the general population should not be underestimated.
