Tobacco consumption and antidepressant use are associated with the rate of completed suicide in Hungary: an ecological study

Alcohol Use Disorder and Associated Factors Among Elderly in Ethiopia

Background

The aim of this study was to investigate the magnitude and associated factors of alcohol use disorder among the elderly living in 3 towns in South West Ethiopia.

Method

Cross-sectional community-based study was done among 382 elderly people aged 60 or more from February to March 2022 in South West Ethiopia. The participants were selected by a systematic random sampling method. Alcohol use disorder, quality of sleep, cognitive impairment, and depression were assessed by using AUDIT, Pittsburgh Sleep Quality Index, Standardized Mini Mental State Examination, and geriatric depression scale, respectively. Also, suicidal behavior, elder abuse, and other clinical and environmental factors were assessed. The data was entered into Epi Data Manager Version 4.0.2 before being exported to SPSS Version 25 for analysis. A logistic regression model was used, and variables with a P-value less than .05 in the final fitting model were stated as independent predictors of alcohol use disorder (AUD).

Result

The magnitude of alcohol use disorder, current alcohol use, and life-time alcohol use among the elderly was 27.5%, 52.4%, and 89.3%, respectively. Also, 7%, 23%, 8.9%, and none of the elderly had nicotine, khat, inhalants, and cannabis use disorder, respectively. Furthermore, AUD was associated with cognitive impairment (AOR, 95% CI; 2.79 (1.47-5.30)), poor sleep quality (AOR, 95% CI; 3.27 (1.23-8.69)), chronic medical illness (AOR, 95% CI; 2.12 (1.20-3.74)), and suicidal ideation (AOR, 95% CI; 5.27 (2.21-12.60)).

Conclusion

Problematic alcohol use was higher among the elderly, and cognitive impairment, poor sleep quality, having chronic medical illness, and suicidal ideation were risk factors for AUD. Therefore, community level screening for AUD and comorbid risk factors among this particular age group and managing them is crucial to prevent further complications due to AUD.

Estimation of the relationship between the persistent decrease of the suicide rate and the changes in sociodemographic composition in Hungary between 1990 and 2011

From the end of the 1980s, the Hungarian suicide rate, which had been until that point the highest in the world for decades, has decreased drastically. The reason behind this decrease was probably due to the changes in numerous and often interlinked risk factors. Studies on this topic have mostly ignored to interrogate to what extent the change of the population composition, for example the improvement of educational level, contributed to the decrease of the rate in the given period? Our aim was to assess the contribution of changes in some sociodemographic factors to the decrease of the suicide rate in Hungary. During the analysis, data from 1990 were compared with data from 2011. For the statistical calculations, the method of “Standardization and Decomposition (SDA)” was used, which according to our best knowledge, has not yet been applied in Hungarian suicide studies. The results show that the improvement of educational level helped to decrease the rate for men by about a third, while for women only by about a tenth. However, the benefit of the improvement in educational attainment during the period investigated was significantly offset by the changes primarily in marital status (the ratios of unmarried and divorced subjects increased for both genders) and in age distribution (the ratio of the elderly persons increased for both genders). The results of our study emphasise the inverse relationship between suicide and educational level and support the hypothesis that we can regard educational policy as indirect health policy.

Factors Associated With Suicidal Ideation in Older Adults From Three Cities in Colombia, 2016

INTRODUCTION

Suicidal ideation refers to thoughts that range from a vague idea of committing suicide to a specific suicide plan.

OBJECTIVE

To explore factors such as demographic, social, family, abuse, risk of depression, habits and health conditions, which influence suicidal ideation in the elderly people in the cities of Medellín, Barranquilla, and Pasto (Colombia), with the intention to identify those associated factors that can be used in public health programs focused on this population.

METHODS

Cross-sectional analytical study was conducted using a secondary source, demographic, social, clinical variables, social support, discrimination, abuse, happiness, depression, functional capacity, and as a dependent variable were asked the question: "Have you ever thought about committing suicide?" A descriptive, bivariate and multivariate analysis was performed.

RESULTS

The median age was ≤ 69 [interquartile range, 11] years, and 58.2% were women. The prevalence of suicidal ideation was 6.4%, and of these, 28.7% had made plans to end their lives, and 66.7% had tried at least once. A statistical association was found with informal employment, cigarette consumption, alcohol and psychoactive substances, risk of depression, having a disability, dissatisfaction with their quality of life, with their health, with their economic situation, as well as feeling unhappy, bad treatment and bad relationships among family members, poor social support, sexual and economic abuse, and finally, discrimination.

CONCLUSIONS

Suicidal ideation in older adults in three cities of Colombia is explained by the sexual and economic abuse that this population is suffering, as well as bad personal relationships between the members of the family of the older adult. The risk of depression increases the probability of having thoughts against one's life.

Stock Market Fluctuations and Self-Harm among Children and Adolescents in Hong Kong

Although a few studies investigated the impact of stock market fluctuations on population health, the question of whether stock market fluctuations have an impact on self-harm in children and adolescents remain unanswered. This study therefore investigated the association between stock market fluctuations and self-harm among children and adolescents in Hong Kong. Daily self-harm attendance records were retrieved from all 18 local Accident and Emergency Departments (AED) from 2001 to 2012. 4931 children and adolescents who committed self-harm were included. The results indicated positive correlation between daily change in stock market index, Hang Seng Index (∇HSI, per 300 points), and daily self-harm incident risk of children and adolescents, without time lag between the two. The incident risk ratio for ∇HSI was 1.09 (p = 0.0339) in children and 1.06 (p = 0.0246) in adolescents. Importantly, non-trading days were found to impose significant protective effect in both groups against self-harm risk. Our results showed that stock market fluctuations were related to self-harm behaviors in children and adolescents. Parents and professionals should be educated about the potential harm of stock market fluctuations and the importance of effective parenting in reducing self-harm among children and adolescents.

Household Factors Associated with Self-Harm in Johannesburg, South African Urban-Poor Households

Introduction

Low and middle income countries bear the majority burden of self-harm, yet there is a paucity of evidence detailing risk-factors for self-harm in these populations. This study aims to identify environmental, socio-economic and demographic household-level risk factors for self-harm in five impoverished urban communities in Johannesburg, South Africa.

Methods

Annual serial cross-sectional surveys were undertaken in five impoverished urban communities in Johannesburg for the Health, Environment and Development (HEAD) study. Logistic regression analysis using the HEAD study data (2006–2011) was conducted to identify household-level risk factors associated with self-harm (defined as a self-reported case of a fatal or non-fatal suicide attempt) within the household during the preceding year. Stepwise multivariate logistic regression analysis was employed to identify factors associated with self-harm.

Results

A total of 2 795 household interviews were conducted from 2006 to 2011. There was no significant trend in self-harm over time. Results from the final model showed that self-harm was significantly associated with households exposed to a violent crime during the past year (Adjusted Odds Ratio (AOR) 5.72; 95% CI 1.64–19.97); that have a member suffering from a chronic medical condition (AOR 8.95; 95% 2.39–33.56) and households exposed to indoor smoking (AOR 4.39; CI 95% 1.14–16.47).

Conclusion

This study provides evidence on household risk factors of self-harm in settings of urban poverty and has highlighted the potential for a more cost-effective approach to identifying those at risk of self-harm based on household level factors.

The possible role of maternal bonding style and CHRNB2 gene polymorphisms in nicotine dependence and related depressive phenotype

OBJECTIVES

Neuronal nicotinic acetylcholinergic receptors (nAChR) and especially α4β2 nAChRs are the major targets for cessation medications and also for some promising antidepressant agents. Furthermore, depressive symptoms pose multifacet difficulties during cessation therapy. However, gene encoding for the β2 subunit of nAChRs has been poorly investigated in association with depression. Since both nicotine dependence (ND) and depressive phenotype are complex disorders, we investigated the effects of a significant early life experience, maternal bonding style (MB) and CHRNB2 gene SNPs on smoking-related depression.

METHODS

We recruited two hundred and thirty-two treatment-seeking smokers in our study. Phenotypic variants were evaluated using the Fagerstrom Test for Nicotine Dependence (FTND), the Zung Self-Rating Depression Scale (ZSDS) and the Parental Bonding Instrument (PBI). Besides the total score (TS) of ZSDS, impulsivity (ZSDS-I) and suicidal ideation (ZSDS-S) were distinguished as phenotypic variable. DNAs were extracted from buccal mucosa samples and one SNP in promoter and two SNPs in 3' UTR of CHRNB2 gene were genotyped. GLM and ANOVA tests were performed for genotype associations and interaction analyses.

RESULTS

Maternal bonding had a significant impact on depressive phenotypes. Low care, high protection and affectionless control (ALC) were associated with ZSDS-TS and all subphenotypes of ZSDS. One SNP, the rs2072660 in 3' UTR, had a significant effect on the FTND score (p=0.010). Direct association of CHRNB2 variants and depressive phenotypes were not significant. However, in interaction with ALC, rs2072660 was significantly associated with ZSDS-S (p=0.005). MB had no significant effect on smoking-related phenotype.

CONCLUSIONS

Our results highlight the important role of 3' UTR in the CHRNB2 gene in the shared molecular background of ND and depressive phenotype. Parental bonding style can be suggested as a significant environmental factor in further GxE studies of depression. The presented significant GxE interaction on smoking-related suicidal subphenotype may help establish further investigations on development of more effective and safer smoking cessation and antidepressant agents.

The meaning of smoking for patients with mental disorder

When patients smoke cigarettes in psychiatric services, it brings to the forefront current ethical and political dilemmas. This study aims to explore the meaning attributed to smoking by mental health patients who smoke and who are hospitalized in a psychiatric ward of a general hospital. This qualitative descriptive study was conducted with 96 smokers who were hospitalized in a psychiatric ward in Brazil. Semi-structured interviews, test of nicotine dependence, and content thematic analysis were carried out. The results show that tobacco has an important role in the lives of psychiatric patients. The meanings they attribute to tobacco use are related to overcoming difficulties that are consequential of mental disorders and of side effects caused by their treatments.

Antidepressant drugs and teenage suicide in Hungary: Time trend and seasonality analysis

OBJECTIVE

The aim of the present study was to analyze the relationship between increasing utilization of antidepressants and lithium, and suicide rate of persons less than 20 years of age in Hungary, with particular regard to seasonal patterns.

METHODS

Time trend analysis was carried out to determine the correlation between antidepressant and lithium prescription patterns in Hungarian persons under age of 20 years as well as seasonal variations within the study period from January 1998 to December 2006.

RESULTS

There was a significant correlation (P = 0.03) between the eight-fold increase in antidepressant + lithium prescriptions and decreasing suicides in young Hungarian people under 20 years of age within the study period. Lithium, selective serotonin reuptake inhibitors (SSRIs) and the group of "other antidepressant drugs" rather than nonselective monoamine reuptake inhibitors and monoamine oxidase-A inhibitors were responsible for this association. No significant association could be drawn from seasonal variation with boys (P = 0.964), girls (P = 0.140), or both genders (P = 0.997).

LIMITATION

Ecological study design.

CONCLUSION

Our findings are in good agreement with large-scale ecological studies showing that the beneficial effect of more widely used antidepressants at a given point could appear on the level of suicide rate of the general population even among patients under the age of 20 years.

Relationship of suicide rates to economic variables in Europe: 2000-2011

BACKGROUND

It is unclear whether there is a direct link between economic crises and changes in suicide rates.

AIMS

The Lopez-Ibor Foundation launched an initiative to study the possible impact of the economic crisis on European suicide rates.

METHOD

Data was gathered and analysed from 29 European countries and included the number of deaths by suicide in men and women, the unemployment rate, the gross domestic product (GDP) per capita, the annual economic growth rate and inflation.

RESULTS

There was a strong correlation between suicide rates and all economic indices except GPD per capita in men but only a correlation with unemployment in women. However, the increase in suicide rates occurred several months before the economic crisis emerged.

CONCLUSIONS

Overall, this study confirms a general relationship between the economic environment and suicide rates; however, it does not support there being a clear causal relationship between the current economic crisis and an increase in the suicide rate.

Investigation of the marked and long-standing spatial inhomogeneity of the Hungarian suicide rate: a spatial regression approach

BACKGROUND

In the last century Hungary had astonishingly high suicide rates characterized by marked regional within-country inequalities, a spatial pattern which has been quite stable over time.

AIMS

To explain the above phenomenon at the level of micro-regions (n=175) in the period between 2005 and 2011.

METHODS

Our dependent variable was the age and gender standardized mortality ratio (SMR) for suicide while explanatory variables were factors which are supposed to influence suicide risk, such as measures of religious and political integration, travel time accessibility of psychiatric services, alcohol consumption, unemployment and disability pensionery. When applying the ordinary least squared regression model, the residuals were found to be spatially autocorrelated, which indicates the violation of the assumption on the independence of error terms and - accordingly - the necessity of application of a spatial autoregressive (SAR) model to handle this problem. According to our calculations the SARlag model was a better way (versus the SARerr model) of addressing the problem of spatial autocorrelation, furthermore its substantive meaning is more convenient.

RESULTS

SMR was significantly associated with the "political integration" variable in a negative and with "lack of religious integration" and "disability pensionery" variables in a positive manner. Associations were not significant for the remaining explanatory variables.

LIMITATIONS

Several important psychiatric variables were not available at the level of micro-regions. We conducted our analysis on aggregate data.

CONCLUSION

Our results may draw attention to the relevance and abiding validity of the classic Durkheimian suicide risk factors - such as lack of social integration - apropos of the spatial pattern of Hungarian suicides.

Elevated incidence of suicide in people living at altitude, smokers and patients with chronic obstructive pulmonary disease and asthma: possible role of hypoxia causing decreased serotonin synthesis

Recent research indicates that suicide rates are elevated in those living at higher altitudes in both the United States and South Korea. A possible mechanism that was proposed is metabolic stress associated with hypoxia. This commentary discusses these results, and also the association between elevated suicide rates and other conditions associated with hypoxia (smoking, chronic obstructive pulmonary disease and asthma). Tryptophan hydroxylase may not normally be saturated with oxygen, so mild hypoxia would decrease serotonin synthesis. Low brain serotonin is known to be associated with suicide. Thus, the commentary proposes and discusses the hypothesis that decreased brain serotonin synthesis associated with hypoxia is a mechanism that may contribute to suicide in conditions causing hypoxia. Finally the commentary proposes various studies that could test aspects of this hypothesis.

Suicide in Hungary-epidemiological and clinical perspectives

Annual suicide rates of Hungary were unexpectedly high in the previous century. In our narrative review, we try to depict, with presentation of the raw data, the main descriptive epidemiological features of the Hungarian suicide scene of the past decades. Accordingly, we present the annual suicide rates of the period mentioned and also data on how they varied by gender, age, urban vs. rural living, seasons, marital status, etc. Furthermore, the overview of trends of other factors that may have influenced suicidal behavior (e.g., alcohol and tobacco consumption, antidepressant prescription, unemployment rate) in the past decades is appended as well. Based on raw data and also on results of the relevant papers of Hungarian suicidology we tried to explain the observable trends of the Hungarian suicide rate. Eventually, we discuss the results, the possibilities, and the future tasks of suicide prevention in Hungary.

Predicting national suicide numbers with social media data

Suicide is not only an individual phenomenon, but it is also influenced by social and environmental factors. With the high suicide rate and the abundance of social media data in South Korea, we have studied the potential of this new medium for predicting completed suicide at the population level. We tested two social media variables (suicide-related and dysphoria-related weblog entries) along with classical social, economic and meteorological variables as predictors of suicide over 3 years (2008 through 2010). Both social media variables were powerfully associated with suicide frequency. The suicide variable displayed high variability and was reactive to celebrity suicide events, while the dysphoria variable showed longer secular trends, with lower variability. We interpret these as reflections of social affect and social mood, respectively. In the final multivariate model, the two social media variables, especially the dysphoria variable, displaced two classical economic predictors – consumer price index and unemployment rate. The prediction model developed with the 2-year training data set (2008 through 2009) was validated in the data for 2010 and was robust in a sensitivity analysis controlling for celebrity suicide effects. These results indicate that social media data may be of value in national suicide forecasting and prevention.

A twin study of depression and nicotine dependence: shared liability or causal relationship?

BACKGROUND

The nature of the relationship between major depression (MD) and phenotypes related to smoking behavior, including nicotine dependence (ND), is complicated. We present results from analyses comparing models wherein MD and ND are influenced by a shared latent factor to one in which causal pathways between phenotypes are examined.

METHOD

Data were collected for 2906 adult male twins from a population-based sample. Structural equation modeling was used to derive path estimates for shared liability and causal models. MD was assessed according to DSM-III-R diagnostic criteria; ND was assessed using the Fagerstrom Test for Nicotine Dependence (FTND).

RESULTS

The best fitting shared liability model included genetic, but not environmental, influences shared between MD and FTND; a small proportion of these shared influences were also common to smoking initiation. The best fitting causal model included a unidirectional causal path from FTND to MD, with no direct genetic correlation between MD and smoking initiation. Model fit statistics indicated that these models provided nearly identical fits to the data, with the causal model providing a slightly superior AIC value.

CONCLUSIONS

The phenotypic association between MD and FTND is likely due to both a causal relationship, wherein increasing levels of nicotine dependence increase one's risk for depression, and to a shared genetic liability between the two.

LIMITATIONS

This sample consists of Caucasian males born in Virginia, and findings might not be generalizable to others. Statistical power was less than ideal.

Cigarette smoking and risk of completed suicide: a meta-analysis of prospective cohort studies

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.

Anxiety sensitivity cognitive concerns predict suicidality among smokers

BACKGROUND

Anxiety along with anxiety-related risk factors is receiving increased attention in regard to its role in elevated suicidality. One such risk factor, anxiety sensitivity (AS), refers to a fear of anxiety-related symptoms. Emerging research indicates that components of AS, particularly the AS subfactor focused on cognitive arousal concerns, are significantly associated with elevated suicidality in samples of diverse clinical outpatients, clinical outpatients with PTSD symptoms, and Air Force cadets undergoing a stressful life experience. Cigarette smokers represent another relevant population for this line of research due to recent reports indicating that cigarette smoking and nicotine dependence may be related to elevated suicidality.

METHODS

Study 1 examined the role of AS and the AS subfactors in a large sample (n=343) of community adult smokers. Study 2 examined the role of AS and AS subfactors in a sample of "pack-a-day" adult smokers (n=78) who were seeking outpatient treatment for substance abuse issues.

RESULTS

Study 1 results were consistent with our a priori hypothesis that AS cognitive concerns would be significantly associated with suicidality. Additionally, after covarying for relevant substance use variables, Study 2 results were also consistent with our hypothesis that AS cognitive concerns were significantly associated with suicidality.

LIMITATIONS

Limitations included the use of suicide related outcomes, not death by suicide, and cross-sectional design.

CONCLUSIONS

These findings suggest that suicide potential in cigarette smokers may be related to AS cognitive concerns and add to the emerging literature suggesting AS cognitive concerns are a risk factor for suicidality.

Suicidal ideation in Huntington disease: the role of comorbidity

Huntington disease (HD) is a neurodegenerative condition characterized by cognitive impairments, motor abnormalities, and psychiatric disturbance. An increased risk for suicide has been documented. The majority of HD research has focused on cognitive and motor features of HD; the implications of psychiatric manifestations have received less consideration. Recent studies have sought to identify the stages of HD in which patients are at increased risk to experience suicidal ideation, though no study has examined possible risk factors for suicidality. The current study examines the presence of psychiatric comorbidity and its involvement in suicidal ideation. Suicidal ideation was examined in 1941 HD patients enrolled in the Huntington Study Group. Of those, 19% (N=369) endorsed current suicidal ideation. Logistic regression analyses indicated that depression/anxiety and aggression/irritability are significant predictors of suicidal ideation. In a subsample with the greatest suicidal ideation, alcohol and drug abuse were also predictive. It is recommended that all individuals with HD (specifically those with features of depression, aggression, substance abuse) have routine suicide assessment; further research is needed to understand the high rate of suicide in HD.

Early substance use initiation and suicide ideation and attempts among students in France and the United States

OBJECTIVE

In response to recent research documenting a link between early substance use and suicidal behaviors among youth, the current study sought to examine the associations between ages of substance use initiation and suicidal behavior among students in France and the USA.

METHODS

Cross-sectional logistic regression analyses based on the 2003 European School Survey Project on Alcohol and Other Drugs (ESPAD) survey (France; n = 13,187) and the 2003 Youth Risk Behavior Survey (YRBS) (United States; n = 15,136) assessed associations between early substance use initiation (i.e., alcohol, cigarette and cannabis/marijuana) and suicide ideation and attempts while controlling for potential confounders.

RESULTS

Early alcohol use initiation (OR(adj) = 1.52; 95% CI 1.17-1.97) and early cannabis/marijuana use initiation (OR(adj) = 2.90; 95% CI 2.20-3.83) were associated with suicide attempt in France. Early smoking was associated with suicide attempt in both France (OR(adj) = 1.92; 95% CI 1.55-2.37) and the USA (OR(adj) = 1.53; 95% CI 1.02-2.28). Sex differences were also noted.

CONCLUSIONS

The associations between substance use initiation and suicidal behaviors differed in the United States and France. These findings, placed into context, can assist the development and implementation of prevention strategies that seek to reduce the harmful consequences of early substance use among youth.
