Prevalence of suicidality during pregnancy and the postpartum

SummaryThis review examined the available prevalence estimates of suicidality (suicide deaths, attempts, and ideation including thoughts of self harm) in pregnancy and the postpartum. Studies that used defined community or clinic samples were identified through multiple electronic databases and contacts with primary authors. Definitions of and measurement of suicide deaths, intentional self-harming behavior, suicide attempts, and thoughts of death and self-harm were varied and are described with each study. While suicide deaths and attempts are lower during pregnancy and the postpartum than in the general population of women, when deaths do occur, suicides account for up to 20% of postpartum deaths. Self-harm ideation is more common than attempts or deaths, with thoughts of self-harm during pregnancy and the postpartum ranging from 5 to 14%. The risk for suicidality is significantly elevated among depressed women during the perinatal period, and suicide has been found to be the second or leading cause of death in this depressed population.

Risk Factors for Late-Life Suicide: A Prospective, Community-Based Study

Despite the fact that people age 65 and older have the highest rates of suicide of any age-group, late-life suicide has a low prevalence, making it difficult to conduct prospective studies. The authors examined risk factors for late-life suicide on the basis of general information collected directly from older subjects participating in a community-based prospective study of aging, the Established Populations for Epidemiologic Studies of the Elderly. Demographic variables, presence of a relative or friend to confide in, alcohol use, and sleep quality were assessed at baseline interview. Baseline and follow-up data were used to determine physical, cognitive, and affective functioning, as well as medical status. Of 14,456 people, 21 committed suicide over the 10-year observation period. Depressive symptoms, perceived health status, sleep quality, and absence of a relative or friend to confide in predicted late-life suicide. Suicide victims did not have greater alcohol use and did not report more medical illness or physical impairment. This study provided additional information about the context of late-life depression that also contributes to suicidal behavior: poor perceived health, poor sleep quality, and limited presence of a relative or friend to confide in.

Collaborative care to improve the management of depressive disorders: a community guide systematic review and meta-analysis

CONTEXT To improve the quality of depression management, collaborative care models have been developed from the Chronic Care Model over the past 20 years. Collaborative care is a multicomponent, healthcare system-level intervention that uses case managers to link primary care providers, patients, and mental health specialists. In addition to case management support, primary care providers receive consultation and decision support from mental health specialists (i.e., psychiatrists and psychologists). This collaboration is designed to (1) improve routine screening and diagnosis of depressive disorders; (2) increase provider use of evidence-based protocols for the proactive management of diagnosed depressive disorders; and (3) improve clinical and community support for active client/patient engagement in treatment goal-setting and self-management. EVIDENCE ACQUISITION A team of subject matter experts in mental health, representing various agencies and institutions, conceptualized and conducted a systematic review and meta-analysis on collaborative care for improving the management of depressive disorders. This team worked under the guidance of the Community Preventive Services Task Force, a nonfederal, independent, volunteer body of public health and prevention experts. Community Guide systematic review methods were used to identify, evaluate, and analyze available evidence. EVIDENCE SYNTHESIS An earlier systematic review with 37 RCTs of collaborative care studies published through 2004 found evidence of effectiveness of these models in improving depression outcomes. An additional 32 studies of collaborative care models conducted between 2004 and 2009 were found for this current review and analyzed. The results from the meta-analyses suggest robust evidence of effectiveness of collaborative care in improving depression symptoms (standardized mean difference [SMD]=0.34); adherence to treatment (OR=2.22); response to treatment (OR=1.78); remission of symptoms (OR=1.74); recovery from symptoms (OR=1.75); quality of life/functional status (SMD=0.12); and satisfaction with care (SMD=0.39) for patients diagnosed with depression (all effect estimates were significant). CONCLUSIONS Collaborative care models are effective in achieving clinically meaningful improvements in depression outcomes and public health benefits in a wide range of populations, settings, and organizations. Collaborative care interventions provide a supportive network of professionals and peers for patients with depression, especially at the primary care level.

Candidate Endophenotypes for Genetic Studies of Suicidal Behavior

Twin, adoption, and family studies have established the heritability of suicide attempts and suicide. Identifying specific suicide diathesis-related genes has proven more difficult. As with psychiatric disorders in general, methodological difficulties include complexity of the phenotype for suicidal behavior and distinguishing suicide diathesis-related genes from genes associated with mood disorders and other suicide-associated psychiatric illness. Adopting an endophenotype approach involving identification of genes associated with heritable intermediate phenotypes, including biological and/or behavioral markers more proximal to genes, is an approach being used for other psychiatric disorders. Therefore, a workshop convened by the American Foundation for Suicide Prevention, the Department of Psychiatry at Columbia University, and the National Institute of Mental Health sought to identify potential target endophenotypes for genetic studies of suicidal behavior. The most promising endophenotypes were trait aggression/impulsivity, early-onset major depression, neurocognitive function, and cortisol social stress response. Other candidate endophenotypes requiring further investigation include serotonergic neurotransmission, second messenger systems, and borderline personality disorder traits.

Suicide and Marital Status in the United States, 1991–1996: Is Widowhood a Risk Factor?

OBJECTIVES This study examined whether marital status is associated with suicide rates among various age, sex, and racial groups, in particular with widowhood among young adults of both sexes. METHODS US national suicide mortality data were compiled for the years 1991-1996, and suicide rates were broken down by race, 5-year age groups, sex, and marital status. RESULTS Data on suicide rates indicated an approximately 17-fold increase among young widowed White men (aged 20-34 years), a 9-fold increase among young widowed African American men, and lesser increases among young widowed White women compared with their married counterparts. CONCLUSIONS National data suggest that as many as 1 in 400 White and African American widowed men aged 20-35 years will die by suicide in any given year (compared with 1 in 9000 married men in the general population).

Suicide prevention in late life: Directions for science and practice

Suicide among the elderly is a critical public health problem, yet there remains limited information on risk factors to target due to the few number of controlled studies that could help isolate and focus on the most potent risk factors. We suggest that because there are no proven, effective interventions showing reduced suicidal behaviors in older adults, the best current approach is to improve detection and treatment of later-life depression. This effort may be especially effective in primary care settings, where the majority of our nations elderly seek and receive their mental health care. We review approaches to assessment and treatment of later life depression that seem most relevant for later life suicide prevention. Testing and determining whether these treatment approaches are effective is an immediate goal on the path to advancing the science and practice of late-life suicide prevention.

Challenges in preventing relapse in major depression: Report of a National Institute of Mental Health Workshop on state of the science of relapse prevention in major depression

On 21 and 22 May 2001, the National Institute of Mental Health convened a workshop to explore imminent scientific opportunities and encourage new research on preventing relapse in major depression, as a part of a larger effort to find treatments capable of producing durable long-term recovery from major depression. Participants considered definitional and developmental perspectives on depression relapse, the prophylactic potential of current treatments and their cost effectiveness and the neurobiological and psychological risk factors for episode return. It was recommended that the definition of the relapse construct be expanded to capture salient features of incomplete recovery or partial response to treatment that are associated with significant functional impairment. This information is often overlooked by the categorical criteria currently in use. With respect to interventions, there was support for sequencing pharmacological remission with psychological prophylaxis. Provision of focal, short-term treatments that embed relapse prevention skills augment the routes to effective prevention available to patients, beyond that afforded by continuation pharmacotherapy. The challenge will be to identify those subgroups of patients for whom each treatment algorithm is indicated. Finally, the link between basic science findings of biological and psychological markers of relapse vulnerability and treatment design needs to be strengthened. This could be accomplished by assessing patients in clinical prevention trials for the presence of, and changes in, relapse vulnerability markers, thereby providing direct, outcome-based data to gauge the protective value of different treatments that modify these markers.

Stress-Moderating Effects Social Support in the Context of Gender and Locus of Control

Using multiple regression, the main and interactive effects of stress, social support, locus of control, and gender on psychological adjustment were investigated. In order to understand the complex interactions found, the adjustment effects of stress and social support were examined within four subgroups: internal and external men and women college students. Both social support and adjustment were assessed with multiple measures. Stress was more strongly related to levels of adjustment for women than for men. The relationships between social support and adjustment varied depending on which social support measure was used, which adjustment measure was used, as well as the locus of control orientation and gender of the subject. External men were the least able to use social support to aid adjustment. In contrast to previous investigations, there were no two-way stress X locus of control interactions. The importance of investigating the interactions of stress-moderating variables in specific subgroups is discussed.

Household family structure and children's aggressive behavior: a longitudinal study of urban elementary school children.

The relationship between contemporary household family structures at fourth-grade and sixth-grade parent- and teacher-rated aggression was examined in an epidemiologically defined population of urban school children. The relationship between family structure and aggression varied by child gender and by parent and teacher ratings in the home and school, respectively. After taking into account family income, urban area, and fourth-grade aggressive behavior, boys in both mother—father and mother—male partner families were significantly less likely than boys in mother-alone families to be rated as aggressive by teachers. No significant relations between family structure and teacher- or parent-rated aggression were found for girls.

Suicidality in Older African Americans: Findings From the EPOCH Study

The authors examined the current frequency of suicidality and associated characteristics in a sample of 835 African-American older adult residents of six urban public housing developments who consented to participate in an intervention trial of mobile outreach. The frequency of passive and active suicidal ideation was 2.5% and 1.4%, respectively. Characteristics of individuals with both active and passive suicidality included elevated anxiety, social dysfunction, somatic symptoms, low social support, lack of a confidant, and low religiosity. Characteristics of those with passive, but not active, ideation also included older age, lower levels of education, elevated depressive symptoms, poorer cognitive functioning, and having recently discussed emotional problems with a healthcare provider. The characteristics of those reporting active, but not passive, ideation included having a history of mental health treatment and reporting no instrumental support. Multivariate analyses indicated that depression and religiosity were uniquely associated with passive suicidal ideation, and life satisfaction and religiosity were uniquely associated with active suicidal ideation. The authors discuss implications of these findings and offer suggestions for research and clinical practice.
