Suicidality and its relationship with depression, alcohol disorders and childhood experiences of violence: results from the ESEMeD study

Neurological, Metabolic, and Psychopathological Correlates of Lifetime Suicidal Behaviour in Major Depressive Disorder without Current Suicide Ideation

INTRODUCTION

Suicidal behaviour (SB) has a complex aetiology. Although suicidal ideation (SI) is considered the most important risk factor for future attempts, many people who engage in SB do not report it.

METHODS

We investigated neurological, metabolic, and psychopathological correlates of lifetime SB in two independent groups of patients with major depression (sample 1: n = 230; age: 18-65 years; sample 2: n = 258; age >60 years) who did not report SI during an index episode.

RESULTS

Among adults (sample 1), SB was reported by 141 subjects (58.7%) and severe SB by 33 (15%). After controlling for interactions, four risk factors for SB emerged: male gender (OR 2.55; 95% CI: 1.06-6.12), negative self-perception (OR 1.76; 95% CI: 1.08-2.87), subthreshold hypomania (OR 4.50; 95% CI: 1.57-12.85), and sexual abuse (OR 3.09; 95% CI: 1.28-7.48). The presence of at least two of these factors had the best accuracy in predicting SB: sensitivity = 57.6% (39.2-74.5); specificity = 75.1% (68.5-82.0); PPV = 27.9% (20.9-37.2); NPV = 91.4% (87.6-94.1). In older patients (sample 2), 23 subjects (9%) reported previous suicide attempts, which were characterized by earlier onset (25 years: OR 0.95: 0.92-0.98), impaired verbal performance (verbal fluency: OR 0.95: 0.89-0.99), higher HDL cholesterol levels (OR 1.04: 1.00-1.07) and more dyskinesias (OR 2.86: 1.22-6.70).

CONCLUSION

Our findings suggest that SB is common in major depressive disorder, even when SI is not reported. In these individuals it is feasible and recommended to investigate both psychiatric and organic risk factors. The predictive power of models excluding SI is comparable to that of models including SI.

Suicide ideation and male-female differences in major depressive disorder

OBJECTIVE

This study aimed to explore male-female differences in suicide ideation (SI) and suicide risk factors in major depressive disorder (MDD).

METHODS

We analysed 482 adults (sample 1) and 438 elderly outpatients (sample 2) with MDD. Sample 1 was treated with different antidepressant combinations (escitalopram; bupropion plus escitalopram; venlafaxine plus mirtazapine) and assessed by means of the Concise Health Risk Tracking (SI), Quick Inventory of Depressive Symptomatology, Altman Mania Rating Scale and Psychiatric Diagnostic Screening Questionnaire. Sample 2 was treated with venlafaxine and assessed using the Hamilton scale for depression, Anxiety Sensitivity Index and Penn State Worry Questionnaire for anxiety, Beck Scale for Suicide Ideation and Repeatable Battery for the Assessment of Neuropsychological Status.

RESULTS

In sample 1, females had greater depression severity (O.R 0.961 99%CI: 0.929 - 0.995), males reported more alcohol abuse (O.R 1.299 99%CI: 1.118 - 1.509) and active SI (O.R 1.109 99%CI: 1.005 - 1.255). In sample 2 men showed more severe SI (O.R 1.067; 99%CI: 1.014 - 1.122) and weight loss (OR = 5.89 99%CI: 1.01 - 34.19), women more gastrointestinal symptoms.

CONCLUSIONS

In these selected samples, although women had more severe depression, men had more suicide risk factors. Such differences might contribute to men's increased suicide risk.

Clinical correlates and prognostic implications of severe suicidal ideation in major depressive disorder

Suicidal ideation (SI) is a risk factor for suicidal behaviour. To ascertain the clinical correlates and prognostic impact of severe SI, we analysed 249 outpatients with major depressive disorder (MDD) and suicidal thoughts included in the COmbining Medications to Enhance Depression outcome (CO-MED) trial. Patients with severe SI (36%) were younger at disease onset (P = 0.0033), more severely depressed (P = 0.0029), had more lifetime suicidal behaviour (P < 0.0001) and psychiatric comorbidities (panic disorder: P = 0.0025; post-traumatic stress disorder: P = 0.0216), and a history of childhood maltreatment (neglect: P = 0.0054; emotional abuse: P = 0.0230; physical abuse: P = 0.0076; sexual abuse: P = 0.0016) than those experiencing low-moderate SI. After controlling for depression score, severe SI was positively correlated with lifetime suicidal behaviour (OR [95% CI]: 1.26 [1.12-1.41]), panic disorder (1.05 [1.00-1.12]), and childhood maltreatment (neglect: 1.93 [1.13-3.30]; physical abuse: 2.00 [1.11-3.69]; sexual abuse: 2.13 [1.17-3.88]), and inversely correlated with age of onset (0.97 [0.95-0.99]) and sleep-onset insomnia (0.76 [0.61-0.96]). Finally, the occurrence of serious lifetime suicidal behaviour was predicted by SI severity (2.18 [1.11-4.27]), bipolar score (1.36 [1.02-1.81]), and childhood sexual abuse (2.35 [1.09-5.05]). These results emphasise the importance of assessing childhood maltreatment and bipolar liability in MDD to estimate suicidal behaviour risk.

Epidemiology of Childhood Witnessing Domestic Violence and Exploration of Its Relationships With Affective Lability and Suicide Attempts in Chinese Young Adults

Childhood witnessing domestic violence (CWDV) exerts short- and long-term negative impacts on emotional and behavioral health. The present study investigated the epidemiological features of CWDV, and its negative impact on psychological outcomes in a sample of Chinese college students. The mediating role of emotion regulation strategies on CWDV associations with psychological outcomes and gender differences in these relationships were examined. A total of 3,126 respondents (1,034 males; 2,086 females; 6 missing data in gender) completed the study questionnaire, which included demographic characteristics, CWDV, and suicide attempt history items as well as the Emotion Regulation Questionnaire (ERQ) and Affect Lability Scale-18 (ALS-18). Overall, 43.03% of the respondents reported CWDV, including 44.87% of males and 42.09% of females. Higher frequencies of CWDV were found to be related to the following factors: unstable marital status of parents; not being an only child; being a left-behind child, family financial difficulties, consumption of alcohol in the past year, and being in relatively poor physical condition. Among males, ERQ suppression scores were significantly higher for those men who experienced "often or every day" CWDV than for men who indicated that they did not have any history of CWDV (Bonferroni-corrected p = 0.047). More frequent CWDV was associated with higher ALS-18 scores and increased risk of suicide attempts in males and females (p < 0.05), and emotion regulation (suppression) was found to mediate the association between CWDV and affective lability among males. This study revealed high rates of CWDV, and serious impacts of CWDV on mental health in male and female Chinese college students. In males, but not females, emotion regulation strategy use, use of suppression, was found to act as a mediator in the association of CWDV with affective lability. Our findings suggest that interventions for individuals with CWDV should focus on the emotional regulation, which may help them improve mental health, especially in males.

Persistence of suicidal ideation within acute phase treatment of major depressive disorder: analysis of clinical predictors

Suicidal ideation (SI) is common in major depressive disorder (MDD), and it is a risk factor for suicidal behaviour. Antidepressants are effective in reducing SI, but in some subjects, SI may persist for weeks. This study aimed to disentangle the contribution of baseline clinical characteristics in SI nonremission at week 6. Research involved 198 outpatients with MDD and SI collected within the Combining Medications to Enhance Depression Outcomes trial and treated with different antidepressant combinations. Although SI decreased from baseline to week 6 ( P < 0.0001), 78 patients (39%) failed to achieve SI remission. Insomnia [OR, 0.72; 95% confidence interval (CI), 0.52-0.99], reduced need for sleep (OR, 0.75; 95% CI, 0.58-0.99), self-confidence (OR, 0.52; 95% CI, 0.32-0.82), cheerfulness (OR, 0.57; 95% CI, 0.33-0.98), and comorbid panic disorder (OR, 0.93; 95% CI, 0.87-0.99) at baseline were associated with lack of SI remission after controlling for baseline depression and SI scores. The combination of baseline SI and insomnia was moderately effective in predicting the lack of SI remission, with a specificity of 80% (95% CI, 72-87%) and an NPV of 68% (95% CI, 63-72%). In individuals with MDD and SI, the presence of insomnia and bipolar features should prompt a search for more effective treatment solutions in order to favour SI remission and prevent suicidal behaviour.

Suicidal Behavior and Its Relationship with Postmortem Forensic Toxicological Findings

Suicide affects all sociodemographic levels, age groups, and populations worldwide. The factors that can increase the risk of suicidal tendencies are widely studied. The aim of this study was to analyze the types and combinations of toxics found in fatal suicide victims with different suicide mechanisms. A total of 355 autopsies were retrospectively studied, and 26 toxics were determined and related to mechanisms of suicide. Hanging (55%), drug overdose (22.7%), and jumping from a height (17.8%) were most represented suicide mechanisms with positive toxicology. Hanging was the most represented in men (50.3%; p = 0.019), while jumping from a height was more represented in women (29.7%, p = 0.028). Drugs of abuse were the most frequent toxics found in men (55.5%; p < 0.001), while medicines were the most frequent type found in women (70.3%, p < 0.001). Alcohol, nordiazepam, cocaine, and venlafaxine were the most consumed toxics. Benzodiazepines and venlafaxine were found in suicides involving drug overdose, hanging, and jumping from a height. In conclusion, most suicides were associated with drug abuse in men. Hanging was more represented in men and jumping from a height in women. Alcohol was present in combination with other toxics and medicines. The toxicological analysis is fundamental to understanding consumption patterns and establishing strategies and protocols for detecting and preventing suicide.

Irritable Mood and Subthreshold Hypomanic Episodes Correlate with More Severe Major Depression

INTRODUCTION

Irritable mood (IM) and subthreshold hypomanic symptoms are reported in half and two-fifths of major depressed subjects respectively, but their clinical and prognostic meanings remain unclear. The aim of this study was to test the clinical usefulness of 2 specifiers in DSM-IV major depressive disorder (MDD): IM occurring during an index episode (IM+) and lifetime episodes of elated mood or IM with at least 2 concurrent hypomanic symptoms (subthreshold hypomanic episodes [SHEs]).

METHOD

We included 482 outpatients with MDD participating in the Combining Medications to Enhance Depression Outcome study (mean age 43.14 ± 12.46 years, 144 males - 30%). The main aim of the original study was to test whether 2 different medications when given in combination as the first treatment step, compared to 1 medication, would improve antidepressant response.

RESULTS

IM + subjects (N = 349; 70%) were younger and more often females, with a more severe depression, a more marked social impairment, and more psychiatric comorbidities. The IM + group was also characterized by higher levels of suicidal ideation and more cases of emotional abuse. The combination of IM+ and SHEs was associated with an even more severe clinical picture. Limitations include the post hoc method, incomplete assessment of bipolar validators (e.g., family history of bipolar illness), personality disorders and suicide attempts.

CONCLUSIONS

The presence of IM and SHEs in MDD correlate with an overall more severe clinical condition.

Economic Evaluation of Public Health Interventions: An Application to Interventions for the Prevention of Violence Against Women and Girls Implemented by the "What Works to Prevent Violence Against Women and Girls?" Global Program

Violence against women and girls (VAWG) has important social, economic, and public health impacts. Governments and international donors are increasing their investment in VAWG prevention programs, yet clear guidelines to assess the "value for money" of these interventions are lacking. Improved costing and economic evaluation of VAWG prevention can support programming through supporting priority setting, justifying investment, and planning the financing of VAWG prevention services. This article sets out a standardized methodology for the economic evaluation of complex, that is, multicomponent and/or multiplatform, programs designed to prevent VAWG in low- and middle-income countries (LMICs). It outlines an approach that can be used alongside the most recent guidance for the economic evaluation of public health interventions in LMICs. It defines standardized methods of data collection and analysis, outcomes, and unit costs (i.e., average costs per person reached, output or service delivered), and provides guidance to investigate the uncertainty in cost-effectiveness estimates and report results. The costing approach has been developed and piloted as part of the "What Works to Prevent Violence Against Women and Girls?" (What Works?) program in five countries. This article and its supplementary material can be used by both economists and non-economists to contribute to the generation of new cost-effectiveness data on VAWG prevention, and ultimately improve the allocative efficiency and financing across VAWG programs.

Childhood maltreatment, psychiatric symptoms, and suicidal thoughts among adolescents receiving substance use treatment services

INTRODUCTION

Childhood maltreatment experiences are associated with future suicidal thoughts and suicide attempts, yet the roles of specific psychiatric symptoms mediating this relation remain to be clarified. To clarify these relations, we tested a model incorporating multiple forms of childhood maltreatment (sexual abuse, physical punishment, emotional neglect), past year psychiatric disorder symptoms during adolescence (anxiety, mood, and conduct disorders) and recent suicidal thoughts.

METHODS

We administered structured interviews to 394 adolescents receiving outpatient substance use treatment services in the Southeastern United States (280 males; Mage = 16.33; SDage = 1.15). Structural equation models (SEMs) were used to evaluate the degree to which relations between childhood maltreatment and suicidal thoughts were mediated by specific past-year psychiatric symptoms.

RESULTS

Mood disorder symptoms significantly mediated the relation between neglect/negative home environment and suicidal thoughts. This path of influence did not vary by gender.

CONCLUSIONS

Childhood maltreatment and subsequent psychopathology influence suicidal thoughts among adolescents receiving substance use treatment services. The findings of the present study have implications for the adaptation and delivery of substance use treatment services to adolescents to enhance treatment engagement and outcomes.

Increased TG/HDL-C in female G allele carriers of rs1061622 at gene of tumour necrosis factor receptor 2 with suicidal ideation

BACKGROUND

Relationships between tumour necrosis factor receptor 2 (TNF-RII), suicidal ideation and levels of serum lipids have not been reported yet. The present study was to explore lipids profiles in Chinese adolescents with different genotypes of TNF-RII rs1061622 and with or without suicidal ideation.

METHODS

Dietary intakes were surveyed by questionnaires. TNF-RII rs1061622 genotypes were examined by polymerase chain reaction restriction-fragment length polymorphism and verified by DNA sequencing. Lipids levels were examined by routine methods.

RESULTS

Higher TC/HDL-C levels were observed in the subjects with suicidal ideation than those without suicidal ideation in the male students, but no significant differences were found in the female counterparts. When both TNF-RII rs1061622 and suicidal ideation were considered, although there was no significant difference of suicidal ideation prevalence between the TT homozygotes and the G allele carriers, the G allele carriers had elevated levels of TG and TG/HDL-C compared with the TT homozygotes only in the female subjects with suicidal ideation. The subjects with suicidal ideation had higher TG/HDL-C levels than those without suicidal ideation only in the female G allele carriers. Both suicidal ideation and TNF-RII rs1061622, together with BMI, gender and fat intakes, were found the predictors of TG/HDL-C levels. Different relationship patterns of lipids levels were discovered between male and female subjects with different genotypes and with or without suicidal ideation.

CONCLUSIONS

Different changes of lipids profiles between the subjects with or without suicidal ideation may result from not only the genders, but also their interactions with TNF-RII rs1061622.

Prevalence and correlates of suicidality in Andalusia (Spain): Results of the epidemiological study PISMA-ep

BACKGROUND

Suicidality is an important public health problem. Hence, the aims of this study are to report prevalence rates and correlates of suicidality in Andalusia (Southern Spain).

METHODS

This is a cross-sectional household survey conducted on a representative sample of adults living in Andalusia. 4507 subjects were interviewed using the Mini International Neuropsychiatric Interview (MINI) to assess suicidality and standardized instruments were employed to evaluate associated variables. A multivariate logistic regression analysis was used to explore independent associations with suicidality.

RESULTS

Current prevalence of suicidality was 6.4%, 4.4% showed death wish, 1.4% had ideas of self-harm, 2.4% had suicidal thoughts, 1.1% had a suicidal plan, 0.6% had attempted suicide during the month prior to the interview, and, lastly, 2.6% reported to have had any sort of suicide attempt during his/her previous life. Independent factors associated with suicidality were being female, older age, not having a stable couple, lower levels of social support, having had physical childhood abuse experience, having experienced an increasing number of stressful life events, higher neuroticism scores, having a family history of mental disorder and nicotine or drugs dependence.

LIMITATIONS

The instrument employed to measure suicidality is a screening tool rather than a more in-depth diagnostic measure. We have not included all potential correlates of suicidality. This is a cross-sectional study which cannot establish causal relationships between exposures and outcomes.

CONCLUSIONS

This is the first epidemiological study in Andalusia on suicidality offering important results of clinical interest for suicide prevention.

From depressive symptoms to suicide risk: Roles of sense of belongingness and acquired capability for suicide in patients with mental disorders

In order to prevent suicides in patients with mental disorders, it was critical to recognize the risk factors and explore the mechanism. Based on depressive symptoms, which were common in patients with mental disorders in consolidation period in China, we constructed a moderated mediating model under the framework of Integrated Motivational-Volitional Model of suicidal behaviour, and examined the mechanism of how depressive symptoms, thwarted belongingness, and acquired capability for suicide influenced suicide risk. In this study, data were collected from 164 patients through four questionnaires, and analyzed with PROCESS macro for SPSS (Hayes, 2008). The result showed that in the predictive effects of depressive symptoms on suicide risk, thwarted belongingness was a partial mediating variable, while acquired capability for suicide played a moderating role in the partial mediating model. Specifically, the predictive effects of depressive symptoms and thwarted belongingness, both as motivation variables, on suicide risk both occurred in the case of the high acquired capability of suicide, which was a volition variable. The research pointed out the interdependence of depressive symptoms and a sense of belongingness, and clarified the critical role of acquired capability for suicide. The integrated perspective could enhance the interpretation of reality, and enlightened those carrying out the practice of suicide intervention to patients with mental disorders.

A systematic review and meta-analysis of the association between alexithymia and suicide ideation and behaviour

BACKGROUND

Alexithymia reflects a difficulty with identifying and expressing emotions. This experience has been proposed as having an association with suicide ideation and behaviour. This review aimed to synthesise the evidence to establish the bivariate and multivariate relationships between alexithymia, and its subcomponents, with suicide ideation and behaviour.

METHODS

Search terms related to alexithymia and suicide ideation and behaviour were searched across nine prominent databases in May 2018. Studies were eligible for inclusion if they reported original empirical quantitative findings from adult samples, used a validated measure of alexithymia, and any measure of suicide ideation or behaviour.

RESULTS

Thirty-four studies were eligible for inclusion in this review. The review found a large effect size for the relationship between alexithymia and suicide ideation (r = 0.54, 95% CI= 0.40-0.65) and a small effect size for the relationship between alexithymia and suicide behaviour (r = 0.25, 95% CI = 0.16-0.34).

LIMITATIONS

A high level of heterogeneity was found in the meta-analysis meaning that results should be interpreted with caution.

CONCLUSION

A positive association was found between alexithymia and suicide ideation and, to a lesser extent, behaviour across a range of clinical and general population samples. This review has potentially important clinical implications, and promotes the need for suicide prevention to focus on emotion regulation skills.

The association of religiosity with suicidal ideation and suicide attempts in the United Kingdom

OBJECTIVE

The goal was to analyze the association of religiosity with suicidal ideation and suicide attempts in a UK nationally representative sample.

METHODS

This study used cross-sectional data from 7403 people who participated in the 2007 Adult Psychiatric Morbidity Survey (APMS). Religion was assessed with the question 'Do you have a specific religion?' with 'yes' and 'no' answer options. Lifetime and past 12-month suicidal ideation and suicide attempts were assessed. The association between religiosity and suicidality was studied in multivariable logistic regression models adjusted for sociodemographic, behavioural, and psychopathological factors.

RESULTS

Compared to those without a religion, the prevalence of past 12-month suicidal ideation (3.2% vs. 5.4%), past 12-month suicide attempts (0.4% vs. 0.9%), lifetime suicidal ideation (11.2% vs. 16.4%), and lifetime suicide attempts (3.6% vs. 6.0%) was lower among those with a religion. In the fully adjusted model, having a religion was significantly associated with lower odds for all types of suicidality except past 12-month suicide attempts: suicidal ideation (past 12-month: OR = 0.71, 95% CI = 0.51-0.99; lifetime: OR = 0.83, 95% CI = 0.69-0.99) and suicide attempts (past 12-month: OR = 0.71, 95% CI = 0.35-1.45; lifetime: OR = 0.69, 95% CI = 0.53-0.90).

CONCLUSION

There is a negative association between religiosity and suicidality in the UK. Future studies should focus on the underlying mechanisms.

The burden of suicidal ideation across Europe: a cross-sectional survey in five countries

BACKGROUND

Suicidal ideation (SI) is an associated risk of depression, affecting 30-40% of the depressed population. However, there is a paucity of studies investigating the impact of SI in Europe. This retrospective observational study examined the burden of SI among adults with major depressive disorder (MDD) in the 2017 National Health and Wellness Survey in five European countries: France, Germany, Italy, Spain, and the UK.

METHODS

Bivariate analyses evaluated group differences between respondents with MDD with and without SI according to demographic characteristics, self-reported health-related quality of life, work productivity and activity impairment (WPAI), and healthcare resource utilization (HRU). Generalized linear models examined group differences country-wise, after controlling for relevant confounders.

RESULTS

Among 52,060 respondents, 3,308 individuals were diagnosed with MDD, comprising SI (n=905) and non-SI (nSI) (n=2403) patients. Adjusted differences (ADs), compared to the general population, were observed using the Medical Outcomes Study Short Form Survey (SF-12v2) mental component summary scores (AD: SI=-20.02, nSI=-10.77), physical component summary scores (AD: SI=-4.49, nSI=-2.50), and EuroQoL-5 Dimensions (AD: SI=-0.34, nSI=-0.15) (for all, p<0.001). Significantly greater WPAI and higher HRU were associated with SI compared to nSI.

CONCLUSION

The results illustrate the unique impact of SI within the MDD population and the need to reduce the burden.

An upbringing with substance-abusing parents: Experiences of parentification and dysfunctional communication

Aim

To increase understanding of the consequences of growing up with substance-abusing parents, including how this can influence the experience of becoming a parent.

Methods

In-depth interviews were conducted with 19 parents who had participated in an Infant and Toddler Psychiatry Unit intervention programme and who had experienced substance-abusing parents in their family of origin. Directed qualitative content analysis was used to analyse the data.

Results

Analysis of the interview material revealed both a high incidence of parentification and a conspiracy of silence concerning the substance abuse that helped generate symptoms of cognitive dissonance in the children. As parents they experience a high degree of inadequacy, incompetence and stress.

Conclusion

A majority of the children who had grown up with substance-abusing parents responded by taking a parenting role for themselves, their siblings and their parents. These children, often well-behaved and seemingly competent, need to be identified and offered support as they risk developing significant psychological and emotional difficulties that can extend into adulthood. They form an extra sensitive group who may need special support up to and including the time when they become parents themselves. This finding underlines the importance of further research on parenting among those who have grown up with abusive parents.

Chronotype and suicide: The mediating effect of depressive symptoms

BACKGROUND

Chronotype is individual characteristic, and people who stay up late are acknowledged to be more likely to experience depressive symptoms as well as impulsivity and suicide. Depression is also associated with suicidality. The purpose of this study was to investigate and analyze the role of depression in its effects on chronotype and suicidality.

METHOD

A total of 5632 university students were recruited as participants. We evaluated their chronotype, depressive symptoms, and suicidality using questionnaires. Correlation analysis, analysis of covariance, and path analysis were performed.

RESULTS

Depressive symptoms and suicidality were higher among individuals with an eveningness chronotype: the greater the depressive symptoms, the higher the suicidality. The results of path analysis showed that the direct effect of suicidality in relation to chronotype was not statistically significant, but the indirect effect of depressive symptoms was statistically significant. This result indicates that depressive symptoms fully mediated the relationship between chronotype and suicidality.

CONCLUSION

Morningness may be a protective factor, not only against depression but also against suicide. To assess the risk of suicide, we must evaluate not only depressive symptoms, but also the effects of chronotype on depressive symptoms.

Intimate partner violence and mental disorders: Co-occurrence and gender differences in a large cross-sectional population based study in Spain

BACKGROUND

Intimate partner violence (IPV) and mental disorders (MD) are important public health problems disproportionally affecting women. We aimed to study the epidemiology of IPV victimization, MD, and co-occurring IPV-MD in Spanish men and women in terms of i) prevalence, ii) association between IPV and MD, and iii) sociodemographic and clinical characteristics associated with IPV, MD, and co-occurring IPV-MD.

METHODS

Community-based cross-sectional study with 4507 randomly selected participants. Measurement instruments (Mini International Neuropsychiatric Interview and set of validated questions about IPV during the last 12 months) were administered by trained interviewers in participants' households. Statistical analyses included multivariate logistic regression models.

RESULTS

The prevalence of IPV was 9.4%, of MD 22.3%, and of co-occurring MD-IPV 4.4%. MD was associated with higher odds of experiencing IPV (OR = 3.6; p < 0.05). Lack of social support, neuroticism, impulsivity, and family history of MD were associated with higher odds of IPV, MD, and co-occurring IPV-MD in men and women. Poor health status was associated with MD and with co-occurring IPV-MD in men and women. In women, not being married was associated with MD and with co-occurring IPV-MD; having a non-Spanish nationality was associated with IPV and co-occurring IPV-MD; and older age with IPV. In men, younger age was associated with MD.

LIMITATIONS

The cross-sectional nature of this study limited our ability to examine causal inferences.

CONCLUSIONS

MD and IPV are strongly associated. Although less frequently than in women, IPV in men is also associated with depression, post-traumatic and mood disorders, which has relevant implications for healthcare delivery.

The relation of childhood trauma to suicide ideation in patients suffering from obsessive-compulsive disorder with lifetime suicide attempts

The aim of this study was to evaluate the relations of childhood trauma (CT) and obsessive-compulsive (OC) symptom dimensions to suicide ideation in patients with obsessive-compulsive disorder (OCD). Seventy OCD outpatients with lifetime suicide attempts and 60 controls were included. Participants completed the Scale for Suicide Ideation (SSI), the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Dimensional Obsessive-Compulsive Scale (DOCS) and the Depression Anxiety Stress Scales (DASS-21). Among OCD patients, 97.1% had current suicide ideation. OCD patients revealed higher scores on CT, suicide ideation, depression and anxiety than controls. The CT history of sexual abuse (SA) and OC symptom dimension of unacceptable thoughts explained suicide ideation. It was concluded that SA and unacceptable thoughts may contribute to high suicidality and have important implications for the assessment and treatment of suicide risk in OCD patients with lifetime suicide attempts.

Noncoding RNAs in Depression

Major depressive disorder (MDD) is a common psychiatric disorder affecting millions of people worldwide, yet its etiology remains elusive. The last decades have seen great advances in our understanding of the genome structure and functional organization. Noncoding RNAs (ncRNAs) are RNAs that do not code for proteins but have important regulatory roles. The investigation of ncRNAs as regulators of gene expression has been a topic of growing interest in health research, including in studies investigating etiological and therapeutic factors in major depression. Several different species of ncRNAs have been identified in association to and have shown to be dysregulated in depressed individuals or in animal models of depression. This review will detail the complex relation between ncRNAs and major depression and the studies that propose mechanisms and pathways that specific ncRNAs may be involved in major depression.

The association between adverse childhood experiences (ACEs) and suicide attempts in a population-based study

OBJECTIVES

To further our understanding of the relationship between Adverse Childhood Experiences (ACEs) and suicidal behaviour, this study investigates the association between three types of ACEs and lifetime suicide attempts, while considering potential gender-specific and mediating effects.

METHODS

Data were obtained from the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH), a cross-sectional, population-based survey comprised of respondents aged 18 or older who provided self-reported data on past experiences of suicide attempts, as well as childhood sexual abuse (CSA), childhood physical abuse (CPA) and parental domestic violence (PDV) (n = 22 559). After testing for ACE by gender interactions, we estimated the odds of lifetime suicide attempts for each ACE and then investigated whether depression, anxiety, substance abuse and chronic pain acted as mediators of the relationship.

RESULTS

The odds of suicide attempts are significantly higher among those with a history of CPA (OR = 3.29; 99.9% CI 2.33-4.64), CSA (OR = 4.42; 99.9% CI 3.14-6.23) or PDV (OR = 2.52; 99.9% CI 1.69-3.76), when ACEs are mutually adjusted. There is little evidence that gender acts as a moderator; however, depression, anxiety, substance abuse and chronic pain appear to partially mediate the associations. Depression alone accounts for about a quarter of the associations with CSA and CPA.

CONCLUSIONS

Mental health factors and chronic pain appear only to partially mediate relationships between ACEs and lifetime suicide attempts. Future research should look at other pathways with the goal of developing multi-level interventions.

Characteristics of suicidal outpatients with mood, anxiety and somatoform disorders: The role of childhood abuse and neglect

BACKGROUND

The most prevalent psychiatric disorders are mood, anxiety and somatoform (MAS) disorders which show high mutual comorbidity, childhood trauma and elevated risk of suicidality. So far, no studies have compared suicide risk in a secondary care population with comorbid MAS disorders. This gap was taken as starting point for the study.

AIMS

In comparing suicidal and non-suicidal MAS patients, the following was examined: suicide risk in the three disorder groups, socio-demographic and clinical characteristics, occurrence of childhood trauma types and contribution of childhood trauma to suicidality.

METHODS

This cross-sectional study compared suicidal (n = 316) versus non-suicidal comorbid MAS outpatients (n = 929) by means of the Mini-International Neuropsychiatric Interview Plus (MINI-Plus), Brief Symptom Inventory (BSI), Short Form Health Survey 36 (SF-36), Dimensional Assessment of Personality Pathology-Short Form (DAPP-SF) and Childhood Trauma Questionnaire (CTQ).

RESULTS

Compared to non-suicidal MAS patients, suicidal MAS patients mostly had mood disorders (single/comorbid), multiple diagnoses, worse functioning, more personality pathology (self-harm) and more childhood neglect and abuse.

CONCLUSION

Especially (comorbid) depressed patients are at risk for suicide, and routine screening and monitoring of childhood trauma and suicidality in them are recommended, along with the timely deployment of appropriate trauma-focused psychotherapy.

Extreme Weight-Control Behaviors and Suicide Risk Among High School Students

BACKGROUND

Suicide is the third leading cause of death for people ages 15-19. Research has established an association across numerous risk factors and suicide, including depression, substance abuse, bullying victimization, and feelings of alienation. However, the connection between disordered eating as manifested in extreme weight-control behaviors (EWCB), and suicidal thoughts, ideation, and attempts among adolescents is less understood. Given the prevalence of adolescent suicide, this investigation examined associations between EWCB and suicide risk among high school students.

METHODS

Data were collected from a convenience sample of 4178 students in grades 9-12 attending 5 public high schools using the Youth Risk Behavior Survey (YRBS) questionnaire. Logistic regressions were used to estimate associations between EWCB and suicide controlling for grade level and race, reported separately by sex.

RESULTS

Students who reported seriously considering suicide had higher odds of exhibiting all 3 EWCBs [adjusted odds ratio (AOR)(male) = 3.0 (confidence interval (CI): 1.4, 6.5); AOR(female) = 4.5 (CI: 2.5, 8.3)]. Moreover, students who reported they made plans about suicide were also more likely to exhibit all EWCBs [AOR(male) = 3.7 (CI: 1.7, 7.9); AOR(female) = 4.2 (CI: 2.3, 7.7)].

CONCLUSIONS

EWCBs were significantly associated with suicide risk, furthering the evidence suggesting a link between disordered eating and suicide. Findings demonstrated the need for school health services that address disordered eating in the effort to reduce adolescent suicide.

Violence Affects Physical and Mental Health Differently: The General Population Based Tromsø Study

This general population-based study examined associations between violence and mental health, musculoskeletal pain, and early disability pension. The prevalence and consequences of good vs. poor adjustment (resilience vs. vulnerability) following encounters with violence were also examined. Data were based on the sixth wave of the "Tromsø Study" (N = 12,981; 65.7% response rate, 53.4% women, M-age = 57.5 years, SD-age = 12.7 years). Self-reported data on psychological (threats) and physical violence (beaten/kicked), mental health (anxiety/depression), musculoskeletal pain (MSP), and granting of disability pension (DP) were collected. Men suffered more violent events during childhood than women did, and vice versa during adulthood. Psychological violence implied poorer mental health and slightly more MSP than physical violence. The risk of MSP was highest for violence occurring during childhood in women and during the last year for men. A dose-response relationship between an increasing number of violent encounters and poorer health was observed. About 58% of individuals reported no negative impact of violence (hence, resilience group), whereas 42% considered themselves as more vulnerable following encounters with violence. Regression analyses indicated comparable mental health but slightly more MSP in the resilience group compared to the unexposed group, whereas the vulnerable group had significantly worse health overall and a higher risk of early granting of DP. Resilience is not an all-or-nothing matter, as physical ailments may characterize individuals adapting well following encounters with violence.
