Han B, Compton WM, Blanco C. Tobacco Use and 12-Month Suicidality Among Adults in the United States. Nicotine Tob Res 2016; 19:39-48.

Abstract
INTRODUCTION To examine how 12-month prevalences of suicidality vary by tobacco use. METHODS Data were from 325 800 adults who participated in the 2008-2014 National Survey on Drug Use and Health. Descriptive analyses and multivariable multinomial logistic regression models were applied. RESULTS Among adults aged 18 or older in the United States during 2008-2014, 27.4% (annual average, standard error [SE] = 0.14%) were never tobacco users, 38.8% (SE = 0.17%) were former tobacco users, 5.9% (SE = 0.07%) were past-year users of other types of tobacco (non-cigarette), 20.2% (SE = 0.13%) were past-year cigarette-only users, and 7.7% (SE = 0.07%) were past-year users of cigarettes plus other types of tobacco; 2.6% (SE = 0.04%) had suicidal ideation only, 0.7% (SE = 0.02%) had suicidal ideation and suicide plan only, and 0.5% (SE = 0.02%) attempted suicide. After controlling for covariates, compared with never tobacco users, past-year users of cigarettes plus other types of tobacco were at elevated risk of all examined suicidality outcomes (adjusted relative risks [ARRs] = 1.2-1.7), and past-year cigarette-only users were at higher risk of suicide attempt (ARR = 1.4). Early age of first tobacco use was associated with higher risk of suicidal ideation and suicide plan among former tobacco users, past-year tobacco users, and past-year cigarette users (ARRs = 1.2-1.6). Among past-year tobacco users, frequencies of cigarette and cigar use were associated with suicide attempt (ARRs = 1.4-1.7). Nicotine dependence was associated with suicide attempt among past-year cigarette users (ARR = 1.2). CONCLUSIONS Tobacco use is associated with 12-month suicidality among adults. Patients who use tobacco should be assessed further for mental health status and suicide risk. IMPLICATIONS Our results revealed that tobacco use is independently associated with the 12-month suicidality outcomes among adults and identified how the prevalences of 12-month suicidality outcomes vary by tobacco use status and use characteristics among adults. These results have important clinical implications. Future research should assess the effectiveness of tobacco use questions as simple screeners for more extensive assessment of mental health status and suicide risk.

The role of anxiety sensitivity cognitive concerns in suicidal ideation: A test of the Depression-Distress Amplification Model in clinical outpatients. Psychiatry Res 2016; 238:74-80. [PMID: 27086214 DOI: 10.1016/j.psychres.2016.02.016] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2015] [Revised: 12/16/2015] [Accepted: 02/12/2016] [Indexed: 11/23/2022]
Abstract
Suicide constitutes a significant public health burden as global suicide rates continue to increase. Thus, it is crucial to identify malleable suicide risk factors to develop prevention protocols. Anxiety sensitivity, or a fear of anxiety-related sensations, is a potential malleable risk factor for the development of suicidal ideation. The Depression-Distress Amplification Model (DDAM) posits that the anxiety sensitivity cognitive concerns (ASCC) subfactor interacts with depressive symptoms to amplify the effects of depression and lead to suicidal ideation. The current study tested the DDAM across the two most widely-replicated factors of depressive symptoms (cognitive and affective/somatic) in comparison to a risk factor mediation model where ASCC are related to suicidal ideation via depressive symptoms. Participants included 295 clinical outpatients from a community clinic. The interaction between ASCC and depressive symptoms in the prediction of suicidal ideation was not significant for either cognitive or affective/somatic symptoms of depression. However, results revealed a significant indirect effect of ASCC through cognitive symptoms of depression in the prediction of suicidal ideation. These cross sectional findings are not consistent with the DDAM. Rather, the relationship may be better conceptualized with a model in which ASCC is related to suicidal ideation via cognitive symptoms of depression.

Abstract
Risk of suicidality during smoking cessation treatment is an important, but often overlooked, aspect of nicotine addiction research and treatment. We explore the relationship between smoking cessation interventions and suicidality and explore common treatments, their associated risks, and effectiveness in promoting smoking reduction and abstinence. Although active smokers have been reported to have twofold to threefold increased risk of suicidality when compared to nonsmokers,1–4 research regarding the safest way to stop smoking does not always provide clear guidelines for practitioners wishing to advise their patients regarding smoking cessation strategies. In this article, we review pharmacological and cognitive behavioral therapy (CBT) options that are available for people seeking to quit smoking, focusing on the relationship between the ability of these therapies to reduce smoking behavior and promote abstinence and suicidality risks as assessed by reported suicidality on validated measures, reports of suicidal ideation, behaviors, actual attempts, or completed suicides. Pharmacotherapies such as varenicline, bupropion, and nicotine replacement, and CBTs, including contextual CBT interventions, have been found to help reduce smoking rates and promote and maintain abstinence. Suicidality risks, while present when trying to quit smoking, do not appear to demonstrate a consistent or significant rise associated with use of any particular smoking cessation pharmacotherapy or CBT/contextual CBT intervention reviewed.

Abstract
BACKGROUND Literature supports a strong relationship between childhood maltreatment and mental illness but most studies reviewed are cross-sectional and/or use recall to assess maltreatment and are thus prone to temporality and recall bias. Research on the potential prospective impact of maltreatment reduction on the incidence of psychiatric disorders is scarce. METHOD Electronic databases and grey literature from 1990 to 2014 were searched for English-language cohort studies with criteria for depression and/or anxiety and non-recall measurement of childhood maltreatment. Systematic review with meta-analysis synthesized the results. Study quality, heterogeneity, and publication bias were examined. Initial screening of titles and abstracts resulted in 199 papers being reviewed. Eight high-quality articles met eligibility criteria. Population attributable fractions (PAFs) estimated potential preventive impact. RESULTS The pooled odds ratio (OR) between any type of maltreatment and depression was 2.03 [95% confidence interval (CI) 1.37-3.01] and 2.70 (95% CI 2.10-3.47) for anxiety. For specific types of maltreatment and depression or anxiety disorders, the ORs were: physical abuse (OR 2.00, 95% CI 1.25-3.19), sexual abuse (OR 2.66, 95% CI 1.88-3.75), and neglect (OR 1.74, 95% CI 1.35-2.23). PAFs suggest that over one-half of global depression and anxiety cases are potentially attributable to self-reported childhood maltreatment. A 10-25% reduction in maltreatment could potentially prevent 31.4-80.3 million depression and anxiety cases worldwide. CONCLUSION This review provides robust evidence of childhood maltreatment increasing the risk for depression and anxiety, and reinforces the need for effective programs and policies to reduce its occurrence.

Abstract
In a sample of 242 women in treatment for severe mental illness (SMI), we used regression analysis to test the hypothesis that lifetime physical and sexual abuse would correlate with self-harm behaviors (thoughts of self-harm and suicide, self-harming behaviors, and suicide attempts) when controlling for psychiatric symptoms, substance abuse, and negative appraisals of trauma. Lifetime physical abuse and alcohol use were the only significant factors in the model. Women with SMI should be screened regularly for physical abuse, alcohol use, as well as thoughts and behaviors related to self-harming behaviors. Limitations of the study include its cross-sectional design.

Abstract
This study examined the association between trauma exposure, PTSD, suicide attempts, and other psychopathology among 316 racially/ethnically diverse HIV-infected men and women who underwent semi-structured psychiatric assessment. In addition, the role of psychological resilience in trauma exposure was examined in the context of neurological symptoms and functional status. Nearly half (47.8%; 151/316) of the participants reported trauma exposure, of which 47.0% (71/151) developed PTSD. Among trauma-exposed individuals, those with a current psychiatric diagnosis reported more neurological symptoms and lower functional status. Trauma exposure without PTSD was associated with a higher rate of panic disorder and substance-induced mental disorders. Trauma-exposed individuals who did not develop PTSD were less likely than those who reported no trauma exposure to meet criteria for major depressive disorder (MDD). Trauma exposure, MDD, borderline personality disorder, and substance-induced mental disorders were independently associated with increased odds of suicide attempt. These results indicate that co-morbid psychiatric disorders are common among trauma exposed individuals with a history of PTSD, but those with trauma exposure who do not develop PTSD are less likely to experience MDD. The role of other co-morbid psychopathologies in the genesis of suicidal behavior among individuals living with HIV deserves further study.

Abstract
Previous studies have indicated that permissive attitudes toward suicide are positively associated with mental illness (e.g., depression and loneliness). Evidence suggests that there are abnormalities in the cognitive and brain functioning of suicidal patients. Nevertheless, there has been no evidence of the correlation between attitudes toward suicide and abnormal brain structure variations in healthy people. Therefore, in this study, we seek to investigate the neuroanatomical differences in healthy participants with regard to attitudes toward suicide. The results show that permissive attitudes toward suicide were significantly correlated with gray matter volume (GMV) in the left dorsolateral prefrontal cortex (DLPFC) and the left cerebellum in the large sample (n=405), which may be related to inefficient inhibitory control of negative emotion. Then, in a subset of healthy individuals with permissive attitudes (n=113), we also observed that stronger permissive attitudes toward suicide were positively related to the larger GMV in the left DLPFC and the left middle temporal gyrus (MTG), which may be associated with sensitivity of emotional feeling. Furthermore, loneliness had a mediating effect on the relation between the DLPFC volume and attitudes toward suicide. Taken together, neuroanatomical differences in healthy participants with permissive attitudes toward suicide may provide a better understanding of permissive attitudes toward suicide as a likely risk factor for suicidal behavior.

Abstract
PURPOSE The purpose of this paper is to assess the reliability and validity of the Spanish version of the Davidson trauma scale (DTS-S) and to determine the prevalence and correlates of post-traumatic stress disorder (PTSD) symptoms in a non-clinical random sample of prison inmates. DESIGN/METHODOLOGY/APPROACH Probabilistic samples of 1,179 inmates from 26 penal institutions in Puerto Rico were selected using a multistage sampling design. Population estimates and correlations were obtained for PTSD, generalized anxiety and depression. The reliability, factor structure, and convergent validity of the DTS-S were assessed. Cross-validation was employed to confirm the results of the factor analyses. FINDINGS Using the cut-offs adopted by the scale's author, 136 (13.4 percent) of the inmates are likely to have current PTSD and 117 (11.6 percent) reach the cut-off for sub-threshold PTSD. Confirmatory factor analysis generated two factors explaining 53 percent of the variance. High reliabilities were obtained for the total scale (α=0.95) and for the frequency and severity scales (α=0.90 and 0.91). Significantly higher DTS-S scores were found for females (t=2.26, p<0.025), for inmates diagnosed with depression or anxiety (t=2.02, p<0.05), and those reporting suicide attempts (t=4.47, p<0.0001). ORIGINALITY/VALUE Findings support that the DTS-S is a reliable and valid measure to assess PTSD symptoms in Latino inmate populations and to identify individuals at risk for the disorder that require confirmatory diagnosis and clinical interventions.

Abstract
PURPOSE The NESARC, a "third-generation" psychiatric epidemiologic survey that integrated detailed measures of alcohol and drug use and problems has been the data source for over >850 publications. A comprehensive review of NESARC findings and their implications is lacking. METHOD NESARC was a survey of 43,093 participants that covered alcohol, drug and psychiatric disorders, risk factors, and consequences. Wave 1 of the NESARC was conducted in 2001-2002. Three years later, Wave 2 follow-up re-interviews were conducted with 34,653 of the original participants. Scopus and Pubmed were used to search for NESARC papers, which were sorted into topic areas and summarized. RESULT The most common disorders were alcohol and posttraumatic stress disorders, and major depression. Females had more internalizing disorders and males had more externalizing disorders, although the preponderance of males with alcohol disorders (the "gender gap") was less pronounced than it was in previous decades. A race/ethnic "paradox" (lower risk among disadvantaged minorities than whites) remains unexplained. Younger participants had higher risk for substance and personality disorders, but not unipolar depressive or anxiety disorders. Psychiatric comorbidity was extensive and often formed latent trans-diagnostic domains. Since 1991-1992, risk for marijuana and prescription drug disorders increased, while smoking decreased, although smoking decreases were less pronounced among those with comorbidity. A nexus of comorbidity, social support, and stress predicted transitions in diagnostic status between Waves 1 and 2. Childhood maltreatment predicted psychopathology. Alcohol and drug use disorders were seldom treated; attitudinal barriers (little perceived need, perceived alcoholism stigma, pessimism about efficacy) were more important in predicting non-treatment than financial barriers. CONCLUSIONS Understanding comorbidity and the effects of early stressors will require research incorporating biologic components, e.g., genetic variants and brain imaging. The lack of treatment for alcohol and drug disorders, predicted by attitudinal rather than financial variables, suggests an urgent need for public and professional education to reduce the stigma associated with these disorders and increase knowledge of treatment options.

Abstract
BACKGROUND Assortative relating is a proposed explanation for the increased occurrence of suicidal behavior among those exposed to suicidal peers. This explanation proposes that high-risk individuals associate with each other, and shared risk factors explain the effect. METHODS Data were obtained from the ADDhealth longitudinal survey waves I and II (n=4834 school attending adolescents). People who reported peer suicidal behavior in the first wave were identified and classified as the exposure group. Potentially confounding variables were identified, and propensity scores were calculated for the exposure variable using logistic regression. Inverse-probability-of-treatment weighted regression estimated the effect of exposure on the risk for a suicide attempt during the first two waves. RESULTS Weighted analysis showed that the group exposed to a friend's suicide attempt had a higher occurrence of suicide attempts in both waves. Exposure to peer suicide attempts was associated with increased suicide attempts at baseline (RR=1.93; 95%CI= 1.23-3.04) and 1-year follow-up (RR=1.70; 95%CI= 1.12-2.60). LIMITATION Only two consecutive years of data are provided. Misclassification and recall bias are possible due to the use of self-report. The outcome may be misclassified due to respondent misunderstanding of what constitutes a suicide attempts, versus non-suicidal self-injury. Non-response and trimming reduced the sample size significantly. CONCLUSIONS Assortative relating did not account for all the variance and is currently not sufficient to explain the increased risk after exposure to peer suicidal behavior. Clinicians should assess for exposure to suicidal behaviors in their patients.

Abstract
BACKGROUND Varenicline and bupropion are commonly prescribed non-nicotine containing smoking cessation agents. Post-marketing reports suggest an increased incidence of psychiatric disturbances associated with varenicline and bupropion. However, pre-existing psychiatric disorders may confound the association between these smoking cessation agents and psychiatric disturbances. We compared the mental health status of individuals using varenicline or bupropion to that of people quitting without medication, current smokers, and non-smokers while controlling for pre-existing conditions. METHODS A cross-sectional design was used. Data were from 2006-2011 Medical Expenditure Panel Survey. Mental health status was assessed using the mental component summary (MCS) from the 12-item Short Form survey (SF-12v2), 2-item Patient Health Questionnaire (PHQ-2), and Kessler 6 Scale (K6). Differences in MCS score were compared using linear regression. Logistic regressions were used to compare positive screenings for depression using PHQ-2 and for psychological distress using K6. RESULTS Of 578 use episodes, 453 (78.38%) were bupropion and 125 (21.62%) were varenicline. After adjusting for potential confounders, mental health status of varenicline users was not different from current smokers or people who quit smoking without medication, but worse than non-smokers; bupropion was strongly associated with lower mental health status relative to all groups across all three measures. CONCLUSION Varenicline was not associated with worse mental health compared to smokers or those who quit without medication, after adjusting for pre-existing psychiatric disorders. Bupropion was associated with worse mental health status than smokers, former smokers who quit without medication, and nonsmokers, even after adjusting for pre-existing psychiatric disorders.

Abstract
Panic attacks (PAs) are highly prevalent among trauma exposed individuals and have been associated with a number of adverse outcomes. Despite high suicide rates among trauma exposed individuals, research to date has not examined the potential relation between panic symptoms and suicidal ideation and behaviors among this high risk population. The current study tested the association of panic with suicidal ideation and behaviors among a large sample of trauma exposed smokers. Community participants (N=421) who reported a lifetime history of trauma exposure were assessed concurrently for current panic, suicidal ideation and behaviors, and psychiatric diagnoses. Those who met criteria for a current panic disorder diagnosis were removed from analyses to allow for the assessment of non-PD related panic in line with the recent addition of the PA specifier applicable to all DSM-5 disorders. Findings indicated that panic symptoms were significantly associated with suicidal ideation and behaviors beyond the effects of depression and number of trauma types experienced. Further, post-traumatic stress disorder (PTSD) diagnostic status significantly moderated this relationship, indicating that the relationship between panic and suicidal ideation and behaviors is potentiated among individuals with a current PTSD diagnosis. This investigation suggests that panic symptoms may be a valuable clinical target for the assessment and treatment of suicidal ideation and behaviors among trauma exposed individuals.

Abstract
This study examined which factors predict future suicide attempts (SAs) among people referred to psychiatric services in the emergency department (ED). It included consecutive adult (age >18 years) presentations (N = 6919) over a 3-year period to the two tertiary care hospitals in Manitoba, Canada. Medical professionals assessed each individual on 19 candidate risk factors. Stepwise logistic regression and receiver operating characteristic curves examined the association between the baseline variables and future SAs within the next 6 months. A total of 104 individuals re-presented to the ED with future SAs. Of the 19 baseline variables, only two independently accounted for the variance in future attempts. High-risk scores using this two-item model were associated with elevated odds of future SA (odds ratio, 3.22; 95% confidence interval, 1.62-6.42; p < 0.01), but this was tempered by a low positive predictive value. Further evaluation is required to determine if this two-item tool could help identify people requiring more comprehensive risk assessment referred to psychiatry in the ED.

Abstract
Background Suicide has been associated with smoking/tobacco use but its association of and change in smoking/tobacco use status with suicide attempt (SA) is not well established. Methods We investigated whether persistent, former tobacco use, initiation, quitting tobacco use, relapse to tobacco use, and DSM-IV nicotine dependence predict independently SA using Wave 1 and 2 data of the National Epidemiologic Survey of Alcohol and Related Conditions. Data from 34,653 US adults interviewed at Wave 1 (2001-02) and Wave 2 (2004-05) were analyzed. The main outcome measure was SA between Wave 1 and Wave 2 as reported at Wave 2. Results Among the 1,673 respondents reporting lifetime SA at Wave 2, 328 individuals reported SA between Wave 1 and Wave 2. Current and former tobacco use at Wave 1 predicted Wave 2 SA independently of socio-demographic characteristics, psychiatric history, and prior SA (Adjusted Odds Ratio (AOR): 1.49; 95% CI: 1.13-1.95, AOR: 1.31; 95% CI:1.01-1.69, respectively versus never tobacco users). The strongest association with SA was observed among former tobacco users who relapsed after Wave 1 (AOR: 4.66; 95% CI: 3.49-6.24) and among tobacco use initiators after Wave 1 (AOR: 3.16; 95% CI: 2.23-4.49). Persistent tobacco use (current tobacco use at both Wave 1 and Wave 2) also had an increased risk of SA (AOR: 1.89; 95% CI: 1.47-2.42). However, former tobacco users in both Waves 1 and 2 did not show a significantly elevated risk for SA in Wave 2 (AOR:1.09, 95% CI: 0.78-1.52) suggesting that the risk resided mainly in Wave 1 former tobacco users who relapsed to tobacco use by Wave 2. DSM-IV nicotine dependence did not predict SA at Wave 2. Conclusion In a representative sample of US adults, relapse, tobacco use initiation, and persistent tobacco use, which are amenable to intervention, were associated with risk of SA.

Abstract
Nearly all mental disorders increase suicide risk; however, some better predict ideation versus attempts. The interpersonal theory of suicide provides a framework to understand these relationships, via the constructs of thwarted belongingness, perceived burdensomeness, and acquired capability. The current study examined the relationships between various mental disorders and theory constructs among 997 adult outpatients, controlling for sex and age. Disorders generally symptomatically associated with social withdrawal or potential liability to others (i.e., depressive and bipolar disorders, social phobia, borderline personality disorder, schizophrenia and other psychotic disorders, certain drug dependence) were uniquely positively associated with thwarted belongingness and perceived burdensomeness. Disorders associated with potential exposure to painful and provocative events (i.e., posttraumatic stress disorder, schizophrenia and other psychotic disorders, certain drug use) were associated with increased acquired capability. Notably, alcohol use disorders, attention-deficit/hyperactivity disorder subtypes, and panic/agoraphobia were negatively associated with thwarted belongingness or perceived burdensomeness; avoidant personality disorder, and certain anxiety disorders and drug use disorders, were associated with decreased acquired capability. Importantly, disorders associated with both thwarted belongingness and perceived burdensomeness may place individuals at greatest risk for suicide if acquired capability develops. Implications for comorbidity and suicide risk assessment and treatment are discussed.

Abstract
Identifying personality disorder (PD) risk factors for suicide attempts is an important consideration for research and clinical care alike. However, most prior research has focused on single PDs or categorical PD diagnoses without considering unique influences of different PDs or of severity (sum) of PD criteria on the risk for suicide-related outcomes. This has usually been done with cross-sectional or retrospective assessment methods. Rarely are dimensional models of PDs examined in longitudinal, naturalistic prospective designs. In addition, it is important to consider divergent risk factors in predicting the risk of ever making a suicide attempt versus the risk of making an increasing number of attempts within the same model. This study examined 431 participants who were followed for 10 years in the Collaborative Longitudinal Personality Disorders Study. Baseline assessments of personality disorder criteria were summed as dimensional counts of personality pathology and examined as predictors of suicide attempts reported at annual interviews throughout the 10-year follow-up period. We used univariate and multivariate zero-inflated Poisson regression models to simultaneously evaluate PD risk factors for ever attempting suicide and for increasing numbers of attempts among attempters. Consistent with prior research, borderline PD was uniquely associated with ever attempting. However, only narcissistic PD was uniquely associated with an increasing number of attempts. These findings highlight the relevance of both borderline and narcissistic personality pathology as unique contributors to suicide-related outcomes.

Abstract
BACKGROUND The association between physical disorders and suicide remains unclear. The aim of this study was to examine the relationship between physical disorders and suicide after accounting for the effects of mental disorders. METHOD Individuals who died by suicide (n = 2100) between 1996 and 2009 were matched 3:1 by balancing score to general population controls (n = 6300). Multivariate conditional logistic regression compared the two groups across physician-diagnosed physical disorders [asthma, chronic obstructive pulmonary disease (COPD), ischemic heart disease, hypertension, diabetes, cancer, multiple sclerosis and inflammatory bowel disease], adjusting for mental disorders and co-morbidity. Secondary analyses examined the risk of suicide according to time since first diagnosis of each physical disorder (1-90, 91-364, ⩾ 365 days). Similar analyses also compared individuals with suicide attempts (n = 8641) to matched controls (n = 25 923). RESULTS Cancer was associated with increased risk of suicide [adjusted odds ratio (AOR) 1.40, 95% confidence interval (CI) 1.03-1.91, p < 0.05] even after adjusting for all mental disorders. The risk of suicide with cancer was particularly high in the first 90 days after initial diagnosis (AOR 4.10, 95% CI 1.71-9.82, p < 0.01) and decreased to non-significance after 1 year. Women with respiratory diseases had elevated risk of suicide whereas men did not. COPD, hypertension and diabetes were each associated with increased odds of suicide attempts in adjusted models (AORs ranged from 1.20 to 1.73). CONCLUSIONS People diagnosed with cancer are at increased risk of suicide, especially in the 3 months following initial diagnosis. Increased support and psychiatric involvement should be considered for the first year after cancer diagnosis.

Abstract
OBJECTIVE Postmarketing analyses and case reports have associated varenicline use with suicidal behaviors. This article reviews postmarketing analyses, case reports, clinical trials, uncontrolled observational studies, controlled observational studies, and studies in smokers with psychiatric problems that have tested this association. METHOD The author searched the literature for relevant reports via computer and other searches to undertake a qualitative, systematic review. RESULTS Two pooled analyses of 10 and 17 placebo-controlled trials failed to find more suicidal outcomes in the varenicline condition. Seven large uncontrolled observational studies reported low rates of suicide outcomes in varenicline users (<0.1%), and 1 study reported a higher rate (6%). Five large controlled observational studies did not find more suicide outcomes in varenicline users than in those using prescribed bupropion or over-the-counter nicotine medications. Small placebo-controlled trials and observational studies of smokers with current psychiatric problems did not find varenicline was associated with suicidal outcomes. CONCLUSIONS Among the more valid study designs (pooled analyses of placebo controlled trials or large controlled observational studies), there is consistent evidence that varenicline either does not cause increased suicide outcomes, or if it does, the effect is very small. Warnings to consumers and clinicians should reflect, not just the results of postmarketing studies, but the results of the more valid research designs.

Abstract
The purpose of this study is to investigate whether the type and number of stressful life events (SLEs) will be associated with suicidal behavior in a 3-year follow-up period in persons with major depressive disorder (MDD). Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative longitudinal survey of mental health in non-institutionalized adults in the United States. The survey consisted of two waves: Wave 1 (2001--2002) and Wave 2 (2004-2005), n = 34,653. Twelve past-year SLEs were assessed at baseline. These SLEs were categorized into the following groups based on previous research: Loss or victimization; Relationship, friendship, or interpersonal stress; Financial stress; and Legal problems. Only respondents with MDD at Wave 1 were included (n = 6,004). Several SLEs were strongly associated with suicide attempts, among which, "serious problems with neighbor, friend, or relative" (adjusted odds ratio [AOR] = 2.21; 95% confidence interval [95% CI]: 1.41, 3.45) and "major financial crisis, bankruptcy, or unable to pay bills" (AOR = 2.31; 95% CI: 1.45, 3.66) were the most robust predictors of suicide attempts even after adjusting for sociodemographic variables and any anxiety, substance use, or personality disorder. People with MDD who had been exposed to certain SLEs are at elevated risk for future suicide attempts, even after accounting for the demographic factors and psychiatric comorbidity.

Abstract
OBJECTIVE Posttraumatic Stress Disorder (PTSD) and childhood abuse are both consistently associated with a higher risk for suicide attempts. We hypothesize that among patients reporting childhood abuse, PTSD diagnoses are correlated with an increased severity of suicidal features. METHOD We investigated 726 adult patients who had attempted suicide. These participants were assessed on lifetime clinical diagnoses and childhood abuse. The association of PTSD and childhood abuse dimensions with age at first suicide attempt, number of suicide attempts, violent attempts, serious attempts and suicide intent was studied. An adjusted multinomial logistic regression was performed to ascertain if childhood abuse and PTSD increased the severity of the suicidal behavior when combined. RESULTS Several types of childhood abuse (emotional, physical and sexual abuse) when combined with a lifetime diagnosis of PTSD showed an increased risk for more suicide attempts, serious attempts, and a higher level of suicidal intent compared with the absence of any or both risk factors. CONCLUSION The combination of PTSD and childhood abuse should be investigated in clinical settings due to an augmented risk for more severe suicidal behavior.

Abstract
Suicide is a leading cause of death among young adults and the rate of suicide has been increasing for decades. A depression distress amplification model posits that young adults with comorbid depression and anxiety have elevated suicide rates due to the intensification of their depressive symptoms by anxiety sensitivity cognitive concerns. The current study tested the effects of anxiety sensitivity subfactors as well as the depression distress amplification model in a very large sample of college students with elevated suicide risk. Participants were 721 college students who were at elevated risk of suicidality (scored>0 on the Beck Scale for Suicide Ideation). Consistent with prior work, anxiety sensitivity cognitive concerns, but not physical or social concerns, were associated with suicidal ideation. Consistent with the depression distress amplification model, in individuals high in depression, anxiety sensitivity cognitive concerns predicted elevated suicidal ideation but not among those with low depression. The results of this study corroborate the role of anxiety sensitivity cognitive concerns and the depression distress amplification model in suicidal ideation among a large potentially high-risk group of college students. The depression distress amplification model suggests a specific mechanism, anxiety sensitivity cognitive concerns, that may be responsible for increased suicide rates among those with comorbid anxiety and depression.

Abstract
OBJECTIVE To determine the degree of risk during the first year after diagnosis with a mental illness. METHODS We used propensity scoring to create a matched sample for all identified suicide attempts and suicide deaths in the province of Manitoba from 1996 to 2009. This study identified 2100 suicide deaths and 8641 attempted suicides. Three control subjects were identified for every case and matched on age, sex, income decile, region of residence, and marital status. Five categories of physician-diagnosed mental disorders were tested: schizophrenia, anxiety, depression, dementia, and substance abuse. Logistic regression was used to determine the risk for suicide attempts and suicide deaths overall, and within 3 time periods since initial diagnosis: 1 to 90 days, 91 to 364 days, and 365 or more days. RESULTS All disorders, except dementia, were independently related to death. All disorders were related to suicide attempts. The risk of dying by suicide was particularly high within the first 90 days after initial diagnosis for many disorders, including depression (adjusted odds ratio [AOR] 7.33; 95% CI 4.76 to 11.3), substance use disorders (AOR 4.07; 95% CI 2.43 to 6.82), and schizophrenia (AOR 20.91; 95% CI 2.55 to 172). Depression and anxiety disorders had elevated risk in the first year for suicide attempts. CONCLUSIONS These data suggest that several mental disorders independently increase the risk of suicide attempts and death by suicide after controlling for all mental disorders and demographic risk factors. Clinicians should be aware of the heightened risk of suicide and suicidal behaviour within the first 3 months after initial diagnosis.

Abstract
Borderline personality disorder is estimated to be present in approximately 6% of outpatient primary care settings. However, the time and energy spent on this population can greatly exceed what primary care doctors are able to spend. This article gives an overview of borderline personality disorder, including the clinical characteristics, epidemiology, and comorbidities, as well as pharmacologic and most important behavioral management. It is our hope that, with improved understanding of the disorder and skills for managing this population, caring for patients with the disorder can be more satisfying and less taxing for both primary care doctors and their patients.

Abstract
We examined associations among six forms of common lifetime traumatic/adverse events and lifetime suicide attempts while controlling for gender, psychiatric symptoms, self-injury, and substance use in 371 community mental health clients with severe mental illness. Most clients (88.1%) reported at least one traumatic event, and more than half had attempted suicide at least once. Regression revealed that three factors were significantly associated with lifetime suicide attempts: lifetime self-injurious behaviors, lifetime physical abuse, and alcohol use. Having been physically abused appears to be uniquely associated with lifetime suicide attempts when other key risk factors are controlled. Limitations include the cross-sectional design.

Abstract
BACKGROUND Suicide rates have risen considerably in the United States Army in the past decade. Suicide risk is highest among those with past suicidality (suicidal ideation or attempts). The incidence of posttraumatic stress disorder (PTSD) and depressive illnesses has risen concurrently in the U.S. Army. We examined the relationship of PTSD and depression, independently and in combination, and rates of past-year suicidality in a representative sample of U.S. Army soldiers. METHODS This study used the DoD Survey of Health Related Behaviors Among Active Duty Military Personnel (DoD HRB) (N=5927). Probable PTSD and depression were assessed with the PTSD Checklist (PCL) and the 10-item short form of the Center for Epidemiologic Studies Depression Scale (CES-D), respectively. Past-year suicidality was assessed via self-report. RESULTS Six percent of Army service members reported suicidality within the past year. PTSD and MDD were each independently associated with past-year suicidality. Soldiers with both disorders were almost three times more likely to report suicidality within the past year than those with either diagnosis alone. Population-attributable risk proportions for PTSD, depression, and both disorders together were 24%, 29%, and 45%, respectively. LIMITATIONS The current study is subject to the limitations of a cross-sectional survey design and the self-report nature of the instruments used. CONCLUSIONS PTSD and depression are each associated with suicidality independently and in combination in the active duty component of the U.S. Army. Soldiers presenting with either but especially both disorders may require additional outreach and screening to decrease suicidal ideation and attempts.

Abstract
Suicide attempters who met criteria for borderline personality disorder (BPD) comorbid with major depressive disorder (MDD) were compared to both suicide attempters suffering from MDD alone and to attempters with comorbid MDD and other personality disorders (PD). Participants were 239 (158 patients with comorbid PD and 81 patients with MDD without comorbidity) inpatients consecutively admitted after a suicide attempt made in the last 24 hours. Suicide attempters with comorbid MDD and BPD had more frequent previous suicide attempts and were more likely to have a history of aggressive behaviors and alcohol and drug use disorders compared with patients suffering from MDD without Axis II comorbidity.

Abstract
BACKGROUND Few studies have examined the effect of risk factor modification on depression incidence. This study estimated the effect of risk factor modification on depression incidence. METHODS Data analyzed were from the Canadian National Population Health Survey (NPHS) - a longitudinal population-based cohort study. The study followed-up a national cohort sample over a 16-year period from 1994 to 2010. Multivariate modified Poisson regression was used to estimate relative risk. RESULTS The cumulative incidence rate of depression during the 16-year follow-up was 12.07%. Being younger adult, female, Caucasian, poor, occasional/abstainer/former drinker, regular smoker, and having chronic disease were significantly associated with an increased risk of developing depression. About 40% of depression incidence (850,000 cases) was potentially attributable to modifiable risk factors (poor income, smoking, and having a chronic disease). A 10% reduction in the prevalence of these modifiable risk factors could potentially prevent about 165,000 cases of depression. LIMITATIONS The calculation of PAFs assumes that there is a causal relationship between a risk factor and depression. However, major depression has multiple causes. The potential effect of risk factor modification on depression incidence may vary by the profile of risk factors assessed in a particular study. Several potentially important risk factors were not included in this study. CONCLUSION Public health campaigns targeted at significant modifiable risk factors could have a profound effect on future depression incidence. Prevention trials are needed to directly evaluate the effect of single and/or multiple risk factors modification on depression incidence.

Abstract
Cigarette smoking has been associated with an increased risk of suicide. Patients with psychosis are more likely to smoke cigarettes and are also at an increased risk of suicide. The aim of this study was to compare risk for suicidal behavior among patients with psychosis who were current smokers, previous smokers and nonsmokers. We studied 1812 of the 1825 participants who took part in the Australian Survey of High Impact Psychosis (SHIP) for whom smoking data was available. We identified predictors for lifetime suicide attempts using univariate logistic regression analysis. These variables were retained for the multiple logistic regression models if they were a significant predictor of lifetime suicide attempts. A series of multiple logistic regressions were then conducted to predict lifetime suicide attempts using current smoking status and lifetime smoking status as independent variables, respectively, while controlling for the retained predictor variables. Current smoking and lifetime smoking were statistically significant predictors of lifetime suicide attempts. However adding the covariates to a logistic regression model reduced this association to non-significance. The strongest predictors were self-harm in the past 12 months, the presence of lifetime depressive symptoms and a diagnosis of psychotic depression. Identification of suicide risk factors is essential for successful suicide prevention. While previous research highlights the importance of cigarette smoking as an important risk factor for suicidal behaviors including in patients with psychosis, these results must be interpreted within the context of methodological issues.

Abstract
INTRODUCTION Research on factors associated with suicidal ideation and suicide attempts has been conducted largely in developed countries. Research on West African countries in particular is lacking. METHODS Data were obtained from the Global School-based Health Survey conducted in Benin in 2009. This was a cross-sectional study of three grades, spanning Junior and Senior High, which sampled a total of 2,690 adolescents. Data on the occurrence of demographic, psycho-social and socio-environmental risk factors were tested using multinomial logistic regression for their association with suicidal ideation and suicide attempts. RESULTS The survey indicated that 23.2% had thought about suicide and 28.3% had made a suicide attempt in the previous year. Anxiety, loneliness, being bullied, alcohol misuse, illicit drug use, and lack of parental support were independently related to the ideation outcomes, suicidal ideation without planning and suicidal ideation with planning. Multinomial regression analysis, using one suicide attempt and multiple suicide attempts as outcomes, revealed that female sex, anxiety, loneliness, being physically attacked, and illicit drug use were associated these outcomes. DISCUSSION The prevalence of suicide attempts reported in the survey is relatively high. It is possible that there are cultural factors that could explain this finding. Our research indicates that many factors are related to the occurrence of suicidal ideation and suicide attempts among youth in Benin. Illicit drug use and violence in particular are associated with a high rate of suicide attempts in Benin. Measures to address these issues may reduce the risk of self-inflicted violence.

Abstract
This study aimed to characterize the profiles of suicide attempts that were attended to in the Hospital of Alagoas in the year 2010. Four hundred sixty-one charts and service bulletins were analyzed. Patients attempting suicide were predominately female. There were significant difference for suicide attempts (SAs) among men and women in the age of 10 to 19 years and 60 to 69 years. Women have tried more suicide aged between 10 and 19 years and men between 60 and 69 years. The ingestion of drugs was the most frequent method for women; and poisoning, use of sharp objects and hanging for men. The results of this study may contribute to elaboration, planning and implementation of preventive measures to reduce cases of SAs.

Abstract
BACKGROUND Latent class analysis (LCA) offers a parsimonious way of classifying common typologies of psychiatric comorbidity. We used LCA to identify the nature and correlates of predominant typologies of Axis I and II disorders in a large and comprehensive population-based sample of U.S. adults. METHODS We analyzed data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (2004-2005; n = 34,653), a population-based sample of U.S. adults. We derived latent classes based on all assessed Axis I and II disorders and examined the relationship between the identified Axis I classes and lifetime psychiatric disorders and suicide attempts, and physical and mental health-related quality of life. RESULTS A four-class solution was optimal in characterizing predominant typologies of both Axis I and II disorders. For Axis I disorders, these included low psychopathology (n = 28,935, 84.0%), internalizing (n = 3693, 9.9%), externalizing (n = 1426, 4.5%), and high psychopathology (n = 599, 1.6%) classes. For Axis II disorders, these included no/low personality disorders (n = 31,265, 90.9%), obsessive/paranoid (n = 1635, 4.6%), borderline/dysregulated (n = 1319, 3.4%), and highly comorbid (n = 434, 1.1%) classes. Compared to the low psychopathology class, all other Axis I classes had significantly increased odds of mental disorders, elevated Axis II classes, suicide attempts and poorer quality of life, with the high psychopathology class having the overall highest rates of these correlates, with the exception of substance use disorders. Compared to the low psychopathology class, the internalizing and externalizing classes had increased rates of mood and anxiety disorders, and substance use disorders, respectively. CONCLUSION Axis I and II psychopathology among U.S. adults may be best represented by four predominant typologies. Characterizing co-occurring patterns of psychopathology using person-based typologies represents a higher-order classification system that may be useful in clinical and research settings.

Abstract
BACKGROUND Suicide-related ideation and behaviors (SRIB) are associated with both alcohol disorders and major depressive disorder (MDD). The objective of this study was to evaluate the relationship of alcohol dependence (AD) and major depression to the risk for lifetime SRIB. METHODS Data from a community-based sample of 1,237 adult Israeli lifetime drinkers assessed with reliable diagnostic measures were analyzed using logistic regression. RESULTS Lifetime SRIB was reported in 4.7% and was more prevalent among participants with AD (9.0%) than among those without AD (4.1%); p-value = 0.01. Although both AD and major depression were associated with SRIB (AD: OR 2.2, 95% CI 1.1 to 4.4; MDD: OR 11.4, 95% CI = 6.4 to 20.4), joint analysis showed that AD without MDD increased risk for SRIB as compared to those without AD or MDD (OR 3.1, 95% CI 1.1 to 9.1), but AD did not increase risk among those with MDD (OR 1.1, 95% CI 0.4 to 2.7). Among those with AD, the severity of subclinical depressive symptoms was associated with increased SRIB. CONCLUSIONS These findings show that AD increases risk for SRIB among individuals without a history of major depression. Suicidal tendencies may be undetected and underdiagnosed in this group because of the absence of major depression and therefore left untreated. These findings should be considered when adopting suicide prevention or treatment strategies for this high-risk subpopulation.

Abstract
BACKGROUND Despite the high rates of comorbidity of post-traumatic stress disorder (PTSD) and alcohol dependence (AD) in clinical and epidemiological samples, little is known about the prevalence, clinical presentation, course, risk factors and patterns of treatment-seeking of co-occurring PTSD-AD among the general population. METHODS The sample included respondents of the Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Weighted means, frequencies and odds ratios (ORs) of sociodemographic correlates, prevalence of psychiatric disorders and rates of treatment-seeking were computed. RESULTS In the general population, the lifetime prevalence of PTSD only, AD only and PTSD-AD was 4.83%, 13.66% and 1.59%, respectively. Individuals with comorbid PTSD-AD were more likely than those with PTSD or AD only to have suffered childhood adversities and had higher rates of Axis I and II disorders and suicide attempts. They also met more PTSD diagnostic criteria, had earlier onset of PTSD and were more likely to use drugs and alcohol to relieve their PTSD symptoms than those with PTSD only; they also met more AD diagnostic criteria than those with AD only and had greater disability. Individuals with PTSD-AD had higher rates of treatment seeking for AD than those with AD only, but similar rates than those with PTSD only. CONCLUSION PTSD-AD is associated with high levels of severity across a broad range of domains even compared with individuals with PTSD or AD only, yet treatment-seeking rates are very low. There is a need to improve treatment access and outcomes for individuals with PTSD-AD.

Abstract
BACKGROUND Research suggests that suicidal behavior in individuals with anxiety disorders is attributable to co-occurring risk factors, such as depression. We argue that these conclusions are founded primarily in statistical adjustments that may obscure independent associations. We explored independent associations between specific anxiety disorders and suicide attempts and ideation by means of propensity score matching, a process that simulates a case-control study by creating matched groups that differ in group status (e.g., diagnosis of a specific anxiety disorder) but that are statistically equivalent on observed covariates. METHODS We made use of the National Comorbidity Survey Replication (NCS-R) and the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), which include a total of 43,935 adults. Diagnoses included agoraphobia without panic disorder, generalized anxiety disorder, panic disorder with or without agoraphobia, posttraumatic stress disorder, social anxiety disorder, and specific phobia. RESULTS Each anxiety disorder was (95% confidence intervals) associated with increased odds of lifetime suicide attempts (odds ratios 3.57-6.64 [NCS-R], 3.03-7.00 [NESARC]) and suicidal ideation (odds ratios 2.62-4.87 [NCS-R], 3.34-10.57 [NESARC]). Odds ratios for each disorder remained statistically significant after matching on diagnostic status of dysthymia, major depressive disorder, alcohol abuse/dependence, substance abuse/dependence, bipolar disorder I, bipolar disorder II, all other anxiety disorders, and on sociodemographic variables. CONCLUSIONS This is the first report to present evidence that each anxiety disorder is associated with suicide ideation and suicide attempts beyond the effects of co-occurring mental disorders. These findings warrant consideration in assessment, intervention, and related policies.

Abstract
BACKGROUND Genetics of Recurrent Early-Onset Depression study (GenRED II) data were used to examine the relationship between posttraumatic stress disorder (PTSD) and attempted suicide in a population of 1,433 individuals with recurrent early-onset major depressive disorder (MDD). We tested the hypothesis that PTSD resulting from assaultive trauma increases risk for attempted suicide among individuals with recurrent MDD. METHODS Data on lifetime trauma exposures and clinical symptoms were collected using the Diagnostic Interview for Genetic Studies version 3.0 and best estimate diagnoses of MDD, PTSD, and other DSM-IV Axis I disorders were reported with best estimated age of onset. RESULTS The lifetime prevalence of suicide attempt in this sample was 28%. Lifetime PTSD was diagnosed in 205 (14.3%) participants. We used discrete time-survival analyses to take into account timing in the PTSD-suicide attempt relationship while adjusting for demographic variables (gender, race, age, and education level) and comorbid diagnoses prior to trauma exposure. PTSD was an independent predictor of subsequent suicide attempt (HR = 2.5, 95% CI: 1.6, 3.8; P < .0001). Neither assaultive nor nonassaultive trauma without PTSD significantly predicted subsequent suicide attempt after Bonferroni correction. The association between PTSD and subsequent suicide attempt was driven by traumatic events involving assaultive violence (HR = 1.7, 95% CI: 1.3, 2.2; P< .0001). CONCLUSIONS Among those with recurrent MDD, PTSD appears to be a vulnerability marker of maladaptive responses to traumatic events and an independent risk factor for attempted suicide. Additional studies examining differences between those with and without PTSD on biological measures might shed light on this potential vulnerability.

Abstract
Empirical work has suggested relationships among suicide-related outcomes and several constructs related to affect dysregulation, notably anxiety sensitivity (AS) and distress tolerance (DT). However, important questions remain, including the relative contributions of these affect regulation variables as well as the direct contribution of DT on suicidal ideation and prior attempts. The current study sought to better elucidate the nature of these relationships by examining AS, DT, and suicidal ideation and attempt in a clinical sample (N=192). Consistent with prior work and prediction, findings revealed a significant relationship between the AS cognitive concerns subfactor and suicidal ideation and suicide attempt history after accounting for the effects of DT, gender, and depressive symptoms. In addition, depressive symptoms significantly moderated the relationship between the AS cognitive concerns subfactor and suicidal ideation. After accounting for the influence of AS, analyses revealed that DT approached significance in predicting suicidal ideation, but did not significantly predict suicide attempt history. These results suggest that elevated AS cognitive concerns are particularly relevant to suicide in the context of depressive symptoms. Clinicians may benefit from implementing AS reduction strategies with individuals who endorse elevated suicide risk as well as elevated AS cognitive concerns.

Abstract
Recent empirical work has revealed a significant relationship between anxiety sensitivity (AS), particularly the AS cognitive concerns subfactor, and suicidality among cigarette smokers. The current study prospectively tested whether an intervention targeting AS (i.e. an AS-augmented smoking cessation program) would predict lower suicidality in a population known to be at increased risk for death by suicide (i.e. cigarette smokers). Participants (N = 169) were randomly assigned to a standard cognitive behavioral smoking intervention or a cognitive behavioral smoking intervention with an AS reduction component. Findings indicate that the participants who received the AS-augmented intervention had lower suicidality compared to those in the standard intervention, even accounting for baseline suicidality, substance use disorder diagnosis, current depression, current anxiety, and current smoking status. As the first examination of the effect of an AS reduction program on suicidality, this study provides initial support for the hypothesis that reducing AS may lead to lower suicidality. Future work should include testing an AS intervention in a sample with elevated suicidality, as well as specifically targeting AS cognitive concerns, which has a stronger and more consistent relationship with suicidality than global AS.

Abstract
Background Suicide claims over one million lives worldwide each year. In the United States, 1 per 10,000 persons dies from suicide every year, and these rates have remained relatively constant over the last 20 years. There are nearly 25 suicide attempts for each suicide, and previous self-directed violence is a strong predictor of death from suicide. While many studies have focused on suicides, the epidemiology of non-fatal self-directed violence is not well-defined. Objective We used a nationally representative survey to examine demographics and underlying psychiatric disorders in United States (US) hospitalizations with non-fatal self-directed violence (SDV). Method International Classification of Disease, 9th Revision (ICD-9) discharge diagnosis data from the National Hospital Discharge Survey (NHDS) were examined from 1997 to 2006 using frequency measures and adjusted logistic regression. Results The rate of discharges with SDV remained relatively stable over the study time period with 4.5 to 5.7 hospitalizations per 10,000 persons per year. Excess SDV was documented for females, adolescents, whites, and those from the Midwest or West. While females had a higher likelihood of self-poisoning, both genders had comparable proportions of hospitalizations with SDV resulting in injury. Over 86% of the records listing SDV also included psychiatric disorders, with the most frequent being affective (57.8%) and substance abuse (37.1%) disorders. The association between psychiatric disorders and self-injury was strongest for personality disorders for both males (OR = 2.1; 95% CI = 1.3–3.4) and females (OR = 3.8; 95% CI = 2.7–5.3). Conclusion The NHDS provides new insights into the demographics and psychiatric morbidity of those hospitalized with SDV. Classification of SDV as self-injury or self-poisoning provides an additional parameter useful to epidemiologic studies.

Abstract
Previous studies have demonstrated individual associations between borderline personality disorder (BPD), panic attacks (PAs), and panic disorder (PD) in relation to suicide attempts (SAs). This study examined the comorbid effects of these variables. Data from wave 2 of the National Epidemiologic Survey of Alcohol and Related Conditions (N = 34,653) were used to examine using logistic regression the relationship between individuals with BPD (n = 562), PA (n = 253), PD (n = 255), comorbid BPD and PD (n = 146), and co-occurring BPD and PA (n = 119) who had attempted suicide. It was found that BPD, PD, and PA are associated with SAs. Comorbid PD and BPD, or PA and BPD, only slightly increased the association of BPD alone with SA. Associations were greatly decreased after controlling for affective dysregulation. These findings emphasize the importance of affective dysregulation in individuals with BPD in relation to suicide attempts.

Abstract
OBJECTIVE Little quantitative research has been conducted on the effect of physical activity (PA) modification on the prevalence of mental disorders in a nationally representative sample. We aimed to provide quantitative evidence regarding the potential effectiveness of PA in the management of mental disorders. METHODS We used data from the national Canadian Community Health Survey of Mental Health and Well-being (CCHS 1.2) designed to represent the approximately the 25 million national community population aged 15 years and over in 2002. RESULTS Around 1 in 10 Canadians reported a 12-month mental disorder. Women reported more mood and anxiety disorders, men more substance dependence. Almost half of Canadians were physically inactive. After adjusting for covariates, physical inactivity was a significant risk factor for common mental disorders, except manic episode. Approximately 780,000 cases nationally are attributable to physical inactivity. A 10% reduction in the rate of physical inactivity would reduce common mental disorders by 167,000 cases, a 25% reduction would result in 389,000 fewer cases. PA was more beneficial for men. CONCLUSIONS Clinicians and public health campaigns targeting individual patients and general populations can improve patients' symptoms and prevent a significant proportion of future mental disorders by increasing the amount of PA.

Abstract
BACKGROUND Thoughts about death and self-harm in old age have been commonly associated with the presence of depression, but other risk factors may also be important. AIMS To determine the independent association between suicidal ideation in later life and demographic, lifestyle, socioeconomic, psychiatric and medical factors. METHOD A cross-sectional study was conducted of a community-derived sample of 21 290 adults aged 60-101 years enrolled from Australian primary care practices. We considered that participants endorsing any of the four items of the Depressive Symptom Inventory -Suicidality Subscale were experiencing suicidal thoughts. We used standard procedures to collect demographic, lifestyle, psychosocial and clinical data. Anxiety and depressive symptoms were assessed with the Hospital Anxiety and Depression Scale. RESULTS The 2-week prevalence of suicidal ideation was 4.8%. Male gender, higher education, current smoking, living alone, poor social support, no religious practice, financial strain, childhood physical abuse, history of suicide in the family, past depression, current anxiety, depression or comorbid anxiety and depression, past suicide attempt, pain, poor self-perceived health and current use of antidepressants were independently associated with suicidal ideation. Poor social support was associated with a population attributable fraction of 38.0%, followed by history of depression (23.6%), concurrent anxiety and depression (19.7%), prevalent anxiety (15.1%), pain (13.7%) and no religious practice (11.4%). CONCLUSIONS Prevalent and past mood disorders seem to be valid targets for indicated interventions designed to reduce suicidal thoughts and behaviour. However, our data indicate that social disconnectedness and stress account for a larger proportion of cases than mood disorders. Should these associations prove to be causal, then interventions that succeeded in addressing these issues would contribute the most to reducing suicidal ideation and, possibly, suicidal behaviour in later life.

Abstract
To review the literature related to recent temperamental and biological findings on borderline personality disorder (BPD) and major depression, the close link between the two disorders, and the latest therapeutical findings on BPD, focusing on the conditions of co-morbidity between depression and BPD. The National Institutes of Health's PubMed database was used to identify indexed studies on BPD, depression and the co-morbidity between the two. Only studies published between 2000 and 2011 were assessed. Similar temperamental features have been demonstrated in BPD and depression. The strong link between the two disorders seems to be widely recognized by scientific community. Psychotherapy and new antipsychotics are the topics of current major interest of research. The therapeutic targets in the case of co-morbidity are BPD features associated with depressive symptoms, thus influencing prognosis. A global assessment is, in fact, fundamental for a successful therapy for the treatment of the several aspects of a complex psychopathological phenomenon.

Abstract
Suicide is one of the major causes of deaths worldwide. Several studies have showed that alcohol use disorders (AUD) are associated with suicide ideation, suicide attempts, and suicide completion. The majority of the theoretical conceptualization and the bulk of evidence on suicidal behavior and AUD are based on investigations of nonfatal cases because data on nonfatal suicidal behaviors are more readily available. This study aims to explore demographic, clinical, and behavioral dimensions in a large sample of alcohol-related suicides compared to an age-gender matched sample of non-AUD suicides to identify specific factors associated with AUD suicides. We conducted a psychological autopsy study with 158 pairs of AUD and non-AUD suicides. Findings showed that AUD suicides have lower educational level, more biological children and were more likely to be heavy smokers (OR=3.32). Cases were more likely to have family history of alcohol (OR=1.73) and drug abuse (OR=3.61). Subjects had similar prevalences of depressive disorders, anxiety disorders or psychotic disorders. AUD suicides were more likely to meet criteria for current cocaine abuse/dependence (OR=6.64). With respect to personality disorders, AUD suicides presented higher prevalence of Antisocial Personality Disorder (OR=4.68), and were less likely to meet criteria for Avoidant (OR=0.26) and Obsessive-Compulsive Personality Disorders (OR=0.35). Impulsivity scores were higher in AUD suicides (p=0.18), as well as aggression scores (p<0.001). Results form the conditional logistic regression models showed that cocaine abuse/dependence (OR=4.20) and Antisocial Personality Disorder (OR=6.24) were associated with AUD suicide. After controlling for impulsive-aggressive behaviors, levels of aggression were the only psychopathological feature statistically different between AUD and non-AUD suicides (OR=1.28). In conclusion, higher levels of aggressive behaviors are a specific characteristic of AUD suicides. Apart from substance-related diagnoses, AUD and non-AUD suicides have comparable Axis I psychiatric diagnoses and familial transmission of suicidal behavior.

Anxiety sensitivity cognitive concerns predict suicidality among smokers. J Affect Disord 2012; 138:239-46. [PMID: 22370063 PMCID: PMC3306523 DOI: 10.1016/j.jad.2012.01.048] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2011] [Revised: 01/11/2012] [Accepted: 01/30/2012] [Indexed: 11/22/2022]
Abstract
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.
