There are inconsistent findings about depression in Asians. This study examined risk factors for depression in Asian and Caucasian adolescents. Stratified bivariate secondary analyses of risk indicators and depressed mood were performed in this cross-sectional study of high school survey data (9th to 12th grades) from 2,542 students (198 Asian). Asians had a higher prevalence of depressed symptoms, but similar risk factors as Caucasians. Smoking and injury at work were major risk factors for depressed mood among Asians. Asian-specific risk factors for depression were being foreign-born and having a work-related injury. Asian and Caucasian teens have similar risk factors for depressed mood, though being foreign born and having a work-related injury are risk factors specific to Asian youth, possibly related to social-economic status. Providers of care in school, such as school nurses, can be important primary screeners of depression for Asian students in particular.

We linked extensive longitudinal data from the Swedish national eating disorders quality registers and patient registers to explore clinical characteristics at diagnosis, diagnostic flux, psychiatric comorbidity, and suicide attempts in 850 individuals diagnosed with binge-eating disorder (BED). Cases were all individuals who met criteria for BED in the quality registers (N = 850). We identified 10 controls for each identified case from the Multi-Generation Register matched on sex, and year, month, and county of birth. We evaluated characteristics of individuals with BED at evaluation and explored diagnostic flux across eating disorders presentations between evaluation and one-year follow-up. We applied conditional logistic regression models to assess the association of BED with each comorbid psychiatric disorder and with suicide attempts and explored whether risk for depression and suicide were differentially elevated in individuals with BED with or without comorbid obesity. BED shows considerable diagnostic flux with other eating disorders over time, carries high psychiatric comorbidity burden with other eating disorders (OR 85.8; 95 % CI: 61.6, 119.4), major depressive disorder (OR 7.6; 95 % CI: 6.2, 9.3), bipolar disorder (OR 7.5; 95 % CI: 4.8, 11.9), anxiety disorders (OR 5.2; 95 % CI: 4.2, 6.4), and post-traumatic stress disorder (OR 4.3; 95 % CI: 3.2, 5.7) and is associated with elevated risk for suicide attempts (OR 1.8; 95 % CI: 1.2, 2.7). Depression and suicide attempt risk were elevated in individuals with BED with and without comorbid obesity. Considerable flux occurs across BED and other eating disorder diagnoses. The high psychiatric comorbidity and suicide risk underscore the severity and clinical complexity of BED.

To identify the predictive factors of anxiety and depression in patients with acute coronary syndrome. Cross-sectional and retrospective study conducted with 120 patients hospitalized with acute coronary syndrome. Factors interfering with anxiety and depression were assessed. Anxiety was related to sex, stress, years of education, and depression, while depression was related to sex, diabetes mellitus, obesity, years of education, and trait-anxiety. Obesity and anxiety were considered predictive factors for depression, while depression and fewer years of education were considered predictive factors for anxiety. Copyright © 2017.

Depression is typically treated as a homogeneous construct despite evidence for distinct cognitive, affective, and somatic symptom dimensions. Anxiety sensitivity (AS; the fear of consequences of anxiety symptoms) is a cognitive risk factor implicated in the development of depressive symptoms. However, it is unclear how lower order AS dimensions (i.e. physical, cognitive, and social concerns) relate to depressive symptom factors. Confirmatory factor analysis, followed by structural equation modeling, were conducted to examine the factor structure of depression and to then examine the relations between these factors and the lower order factors of AS. This study was conducted in a sample of 374 adults (M age = 35.5, 54.3% female) with elevated levels of psychopathology (89.2% meeting criteria for at least one DSM-5 diagnosis, 25.6% primary depressive disorder). In this study a two-factor model of depression, composed of Cognitive and Affective/Somatic factors, was superior to one- and three-factor solutions. AS cognitive concerns were related to both cognitive and affective/somatic symptoms of depression. Neither of the other AS dimensions was related to depression symptom dimensions. These findings provide a better understanding of the relations between AS and depression symptoms.

Substorm injections bring energetic particles to the inner magnetosphere. But the role of the injected population in building up the storm time ring current is not well understood. By surveying Los Alamos National Laboratory geosynchronous data during 34 storm main phases, we show evidence that at least some substorm injections can contribute to substorm-time scale SYM-H/Dst depressions in the main phase of storms. For event studies, we analyze two typical events in which the main-phase SYM-H index exhibited stepwise depressions that are correlated with particle flux enhancement due to injections and with AL index. A statistical study is performed based on 95 storm time injection events. The flux increases of the injected population (50-400 keV) are found proportional to the sharp SYM-H depressions during the injection interval. By identifying dispersionless and dispersive injection signals, we estimate the azimuthal extent of the substorm injection. Statistical results show that the injection regions of these storm time substorms are characterized with an azimuthal extent larger than 06:00 magnetic local time. These results suggest that at least some substorm injections may mimic the large-scale enhanced convection and contribute to sharp decreases of Dst in the storm main phase.

Background To further understand the relationship between anxiety and depression, this study examined the factor structure of the combined items from two validated measures for anxiety and depression. Methods The participants were 406 patients with mixed psychiatric diagnoses including anxiety and depressive disorders from a psychiatric outpatient unit at a university-affiliated medical center. Responses of the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI)-II, and Symptom Checklist-90-Revised (SCL-90-R) were analyzed. We conducted an exploratory factor analysis of 42 items from the BAI and BDI-II. Correlational analyses were performed between subscale scores of the SCL-90-R and factors derived from the factor analysis. Scores of individual items of the BAI and BDI-II were also compared between groups of anxiety disorder (n = 185) and depressive disorder (n = 123). Results Exploratory factor analysis revealed the following five factors explaining 56.2% of the total variance: somatic anxiety (factor 1), cognitive depression (factor 2), somatic depression (factor 3), subjective anxiety (factor 4), and autonomic anxiety (factor 5). The depression group had significantly higher scores for 12 items on the BDI while the anxiety group demonstrated higher scores for six items on the BAI. Conclusion Our results suggest that anxiety and depressive symptoms as measured by the BAI and BDI-II can be empirically differentiated and that particularly items of the cognitive domain in depression and those of physical domain in anxiety are noteworthy.

Family history of depression is an important risk factor for depression. The aim of this study was to examine whether the effect of family history of depression is confounded by individual and familial socioeconomic factors (i.e., country of origin, educational attainment, family income and mobility) and neighborhood environmental factors (i.e., neighborhood deprivation and neighborhood social capital). The study population comprised 188,907 individuals aged 20-44 years from a nationwide sample of primary care centers in Sweden. Among these individuals, 22,014 with a first event of depression (6,486 men and 15,528 women) were identified during the 7-year follow-up period. Family history of depression was defined as depression in at least one parent. Cross-classified multilevel logistic regression models were used to calculate odds ratios with 95% credible intervals. Increased familial odds were observed after adjustment for individual and familial socioeconomic factors and neighborhood environmental factors for both men and women. Our results suggest that family history of depression is an independent risk factor for depression. Offspring of parents with depression are important targets for disease prevention, regardless of individual and familial socioeconomic factors and neighborhood environmental factors.

Studies of erythrocyte (RBC) cation fluxes and concentrations in hyperthyroid subjects have recently been reported with the suggestion that Na-K ATPase activity was decreased. We have studied tha kinetics of total and ouabain-sensitive K+ uptake utilizing 86Rb as a tracer in the intact erythrocytes of 7 hyperthyroid subjects and compared the results of those of a healthy control population. We find total K+ transport is depressed in the RBC of hyperthyroid subjects. The Vmax for K+ transport for hyperthyroid subjects is 1.8 +/- 0.17 x 10(-4) mM K+/10(9) RBC/hour versus a control of 2.3 +/- 0.14 x 10(-4) mM K+/10(9) RBC/hour. This depression in Vmax is evident in spite of no significant differences in the Km for the system when hyperthyroid subjects (2.7 +/- 0.19 mM) are compared to controls (2.38 +/- 0.21 mM). Further, the depressed K+ transport appears to be the result of depressed ouabain--insensitive K+ transport. Although the percent of the ouabain-sensitive K+ transport is greater in the hyperthyroid subject (82.5%) versus controls (72.5%), this simply reflects a relative change in a system where total transport is dropping but the ouabain-sensitive component is remaining unchanged. None of these findings can be directly or indirectly related to thyroid hormone and it is suggested that the ion transport changes reflect factors independent of thyroid hormone.

A preliminary study of the application of HCMM satellite data to define initial and boundary conditions for numerical models: A case study in St. Louis, Missouri

Infrared and visible HCMM data were used to examine the potential application of these data to define initial and boundary conditions for mesoscale numerical models. Various boundary layer models were used to calculate the distribution of the surface heat flux, specific humidity depression (the difference between the specific humidity in the air at approxmately the 10 m level and the specific humidity at the ground), and the eddy vicosity in a 72 km by 72 km area centered about St. Louis, Missouri. Various aspects of the implications of the results on the meteorology of St. Louis are discussed. Overall, the results indicated that a reasonable estimate of the surface heat flux, urban albedo, ground temperature, and specific humidity depression can be obtained using HCMM satellite data. Values of the ground-specific humidity can be obtained if the distribution of the air-specific humidity is available. More research is required in estimating the absolute magnitude of the specific humidity depression because calculations may be sensitive to model parameters.

Symptoms of depression include feelings of sadness, loneliness, suicidal ideation, and self-dislike. Adolescent depression is viewed as a problem in Japan, but there is little research on the correlates of depression in Japanese youth. Therefore, the purpose of this study was to investigate the prevalence of depression in Japanese youth and to examine correlates of depression using a risk and promotive factor framework. This study examined the symptoms of depression among 802 Japanese youth attending postsecondary schools in the Sapporo area. Separate analyses were conducted for males and females to determine whether the importance of risk and promotive factors varied by gender. The results showed that many factors that had been linked to depressive symptoms in Western samples were predictive of depressive symptoms in Japanese youth. The risk and promotive factors accounted for 50% and 59% of the variance in depressive symptoms for the female and male subsamples, respectively.

Objectives Examine association of appetite loss symptoms to neurocognitive performance in late-life depression (LLD). Methods Cross-sectional data from individuals aged 60+ with Major Depressive Disorder (N =322). Participants received clinical assessment of depression and neuropsychological testing. Factor analysis was used to characterize depression symptom factors, and composite scales were developed for episodic memory, psychomotor executive functions, verbal fluency, and working memory span. Results Factor analysis produced a five-factor solution: (1) Anhedonia/Sadness, (2) Suicidality/Guilt, (3) Appetite/Weight Loss, (4) Sleep Disturbance, and (5) Anxiety/Tension. In separate multivariate models for each neurocognitive domain and including all 5 depression factors, higher appetite-loss-related symptoms were associated with lower performance in episodic memory, psychomotor executive functions, and verbal fluency; results were significant with covariates of age, education, race, sex, age of depression onset, and illness burden. No other depression factors were associated with neurocognitive performance in these models. In an additional set of models, the Appetite factor mediated the association between global depression severity and neurocognitive performance. Discussion A factor of appetite and weight loss symptoms in LLD was uniquely associated with neurocognitive performance, in contrast to lack of association among other depression symptom factors. Conclusion Cognitive deficits are a major adverse outcome of LLD, and prominent appetite loss during acute depression may be a marker for these deficits, independent of overall depression severity. Research is needed to understand the mechanisms that may explain this association, and how it is related to the cognitive and symptomatic course of LLD. PMID:25315155

2013-06-01

Postnatal depression has a serious impact on new mothers and their children and families. Risk factors identified include a history of depression, multiparity, and young age. The study aimed to investigate factors associated with experiencing antenatal depression and developing subsequent postnatal depression. The study utilized survey data from 5332 women about their experience and well-being during pregnancy, in labor, and postnatally up to 3 months. Prespecified sociodemographic and clinical variables were tabulated against the incidence of antenatal depression and postnatal depression. Binary logistic regression was used to estimate the effects of the principal underlying variables. Risk factors for antenatal depression were multiparity, black and minority ethnic (BME) status, physical or mental health problems, living in a deprived area, and unplanned pregnancy. Different factors for postnatal depression were evident among women who had experienced antenatal depression: multiparity and BME status were protective, whereas being left alone in labor and experiencing poor postnatal health increased the risk of postnatal depression. This study confirms previous research on risk factors for antenatal depression and stresses the importance of continuous support in labor and vigilance in the postnatal period regarding the potential ill effects of continuing postnatal health problems.

Depression is a common mental health problem with a higher prevalence in medical students than in the general population. This study aims to investigate the association between depressive symptoms, particularly those in each domain of the Center for Epidemiological Studies Depression (CES-D) Scale, and related factors. A cross-sectional study was conducted with a random sample of 1319 medical students at Haiphong University of Medicine and Pharmacy in 2016. The CES-D scale and a self-reported questionnaire were used to identify the prevalence of depressive symptoms and related risk factors. Univariate and multivariate logistic regression were performed to assess the risk factors associated with depressive symptoms and the score for each structure factor. Depressive symptoms were observed in 514 (39%) students, including more males than females (44.2% vs 36.9%, p = 0.015). Students whose mothers' highest education level was primary school had a higher prevalence of depressive symptoms than students whose mothers had higher education levels (p = 0.038). There was a significant relationship between depressive symptoms and stressful life events, especially a decline in personal health. A higher correlation was found between the somatic complaints and depressive affect domains. The impacts of risk factors differed for each domain of the depression scale. Only the factor of achieving excellence showed no statistically significant associations with depressive symptoms and the scores on the four domains considered in this study. The high prevalence of depressive symptoms among medical students with risk factors and the impact of these risk factors on each domain of depression scale need further clarification to alleviate depression in students during their medical training.

The aim of this study was to examine the symptomatic dimensions of depression in a large sample of patients with major depressive disorder (MDD) in the primary care (PC) setting by means of a factor analysis of the Zung self-rating depression scale (ZSDS). A factor analysis was performed, based on the polychoric correlations matrix, between ZSDS items using promax oblique rotation in 1049 PC patients with a diagnosis of MDD (DSM-IV). A clinical interpretable four-factor solution consisting of a core depressive factor (I); a cognitive factor (II); an anxiety factor (III) and a somatic factor (IV) was extracted. These factors accounted for 36.9% of the variance on the ZSDS. The 4-factor structure was validated and high coefficients of congruence were obtained (0.98, 0.95, 0.92 and 0.87 for factors I, II, III and IV, respectively). The model seemed to fit the data well with fit indexes within recommended ranges (GFI = 0.9330, AGFI = 0.9112 and RMR = 0.0843). Our findings suggest that depressive symptoms in patients with MDD in the PC setting cluster into four dimensions: core depressive, cognitive, anxiety and somatic, by means of a factor analysis of the ZSDS. Further research is needed to identify possible diagnostic, therapeutic or prognostic implications of the different depressive symptomatic profiles.

2002-02-01

Agreement on the factor structure of the Hamilton Depression Rating Scale (HDRS) has not been consistent among studies, and some investigators argued that the scale's factor structure is not reliable. This study aimed at shedding more light on this debated issue. We studied 186 adults with unipolar depression (Major Depressive Disorder, n=80; Dysthymic Disorder, n=71; Depressive Disorder Not Otherwise Specified, n=25; Adjustment Disorder, n=10). They had no comorbid DSM-IV axis I or axis II disorders, and had received no treatment with antidepressant drugs in the previous 2 months. The factor structure of the scale was studied using the principal factor method, followed by oblique rotation. Factor scores were computed for each subject using the regression method. Using the scree-test criterion for factor extraction, we obtained a four-factor solution, explaining 43.8% of total variance. The four factors extracted were identified as (1) somatic anxiety/somatization factor; (2) a psychic anxiety dimension; (3) a pure depressive dimension; and (4) anorexia factor. Patients with Major Depressive Disorder scored significantly higher than patients with other diagnoses on the pure depressive dimension. These results need to be replicated in different cultures, using analogous factoring techniques. Though not exhibiting factorial invariance in the stricter sense of the term, the 17-item HDRS did exhibit a relatively reliable factor structure. Our analysis provides further evidence that the scale is multidimensional. However, as long as the multidimensional character of the scale is taken into account the scale should be able to play a useful role in clinical research.

The aim of the present study was to investigate the differences in the prevalence of and risk factors for elderly depression between urban and rural areas in Japan and to further understanding of the features of elderly depression. A multistage, random sampling procedure and mailing method were used in urban and rural areas in Kumamoto Prefecture. A total of 2,152 participants aged 65 years and older were evaluated for depression using the Geriatric Depression Scale (GDS). Factors associated with depression were also examined. In order to assess the relationship between risk factors and subjective happiness, the Philadelphia Geriatric Center Morale Scale (PGC-MS) was used. Depressive symptoms were associated with living alone, being unemployed, chronic illness, sleep disturbance, suicidal ideation, financial strain, and poor social support; the risk factors for elderly depression were almost the same in the two areas. Although three factors (financial strain, work status, and PGC-MS) were significantly associated with depression in both areas on logistic regression analysis, sleep disturbance was significant only for the urban area, and poor social support was significant only for the rural area. Although factors related to depression did not differ markedly between urban and rural elderly people, some risk factors differed between the two areas. Effective intervention programs for elderly depression should pay more attention to regional differences.

To explore the relationship between family environment and depressive symptoms and to evaluate the influence of hard and soft family environmental factors on depression levels in a large sample of university students in China. A multi-stage stratified sampling procedure was used to select 6,000 participants. The response rate was 88.8%, with 5,329 students completing the Beck Depression Inventory (BDI) and the Family Environment Scale Chinese Version (FES-CV), which was adapted for the Chinese population. Differences between the groups were tested for significance by the Student's t-test; ANOVA was used to test continuous variables. The relationship between soft family environmental factors and BDI were tested by Pearson correlation analysis. Hierarchical linear regression analysis was conducted to model the effects of hard environmental factors and soft environmental factors on depression in university students. A total of 11.8% of students scored above the threshold of moderate depression (BDI≧14). Hard family environmental factors such as parent relationship, family economic status, level of parental literacy and non-intact family structure were associated with depressive symptoms. The soft family environmental factors--conflict and control--were positively associated with depression, while cohesion was negatively related to depressive symptom after controlling for other important associates of depression. Hierarchical regression analysis indicated that the soft family environment correlates more strongly with depression than the hard family environment. Soft family environmental factors--especially cohesion, conflict and control--appeared to play an important role in the occurrence of depressive symptoms. These findings underline the significance of the family environment as a source of risk factors for depression among university students in China and suggest that family-based interventions and improvement are very important to reduce depression among university students.

Risk factors for depression in community-treated epilepsy: systematic review.

2015-02-01

Depression is one of the most common psychiatric comorbidities in epilepsy; however, the factors contributing to this association remain unclear. There is a growing consensus that methodological limitations, particularly selection bias, affect many of the original studies. A systematic review focussed on community-based studies offers an alternative approach for the identification of the risk factors for depression. Searches were performed in MEDLINE (Ovid), 2000 to 31 December 2013, EMBASE, and Google Scholar to identify studies examining risk factors for depression in epilepsy. Community-based studies of adults with epilepsy that reported at least one risk factor for depression were included. The search identified 17 studies that met selection criteria, representing a combined total of 12,212 people with epilepsy with a mean sample size of 718. The most consistent risk factors for depression were sociodemographic factors, despite the fact that most studies focus on epilepsy-related factors. Most studies lacked a systematic conceptual approach to investigating depression, and few risk factors were consistently well studied. Future community-based studies require a detailed systematic approach to improve the ability to detect risk factors for depression in epilepsy. Psychological factors were rarely studied in community-based samples with epilepsy, although the consistent association with depression in the few studies that did suggests this warrants further examination.

To examine the effects of different predictors on the incidence and severity of postpartum depression (PPD) symptoms in a Thai population. In this case control study we delineate the clinical, demographic and socio-economic risk factors associated with PPD symptoms. We used the Edinburgh Postnatal Depression Scale (EPDS) 4-6 weeks postpartum to divide parturients into those with (n = 53) and without (n = 260) PPD using a cutoff score of 11. This study confirms previous risk factors for PPD (i.e. a history of lifetime major depression and PPD, a history of depression during pregnancy, multi-parity, unwanted pregnancy, childcare stress, premenstrual syndrome, pain symptoms in the early puerperium), and describes new risk factors (i.e. use of caffeine during pregnancy and baby feeding problems). There are significant associations between (a) a lifetime history of major depression and depression during pregnancy, a history of postpartum depression and lifetime mania; and (b) a history of lifetime mania and a history of depression during pregnancy and a history of postpartum depression. A history of lifetime major depression and depression during pregnancy are the most important risk factors for postnatal depression, suggesting that sensitization processes increase risk towards postpartum depression. Postpartum depression may be a subtype of unipolar depression or bipolar disorder. Copyright © 2016 Elsevier B.V. All rights reserved.

The aim of this study was to examine whether self-esteem mediates the relationship between family factors and depressive symptoms in young adults. Participants completed self-report questionnaires about overall family environment, conflict with mother or father, parental rearing, self esteem, and depressive symptoms. Self-esteem was found to mediate the relationship between the combined family factors and depressive symptoms. When examined simultaneously, none of the individual family variables uniquely predicted depressive symptoms or self-esteem. However, separate analysis of each of the three family factors provided evidence for self-esteem mediating the relationship between parental conflict and depressive symptoms, and the relationship between parental care and depressive symptoms. Self-esteem may play a role in the mechanism underlying the link between parent-offspring relationship factors and depressive symptoms.

Prenatal depression is a significant predictor for postpartum depression. However, there is a lack of research on risk factors for Korean women related to prenatal depression and the relationship between prenatal depression during the three trimesters and postpartum depression. Therefore, aims of this study were (1) to identify the prevalence of depression during all three trimesters and the postpartum period, (2) to evaluate the relationship between prenatal depression in each trimester and postpartum depression, and (3) to identify the relationship and differences in prenatal depression based on sociodemographic factors in Korean women. One hundred and fifty three Korean women were recruited from three maternity clinics in Korea. Prenatal and postpartum depressions were evaluated in the first, second (24-26 weeks), third (32-34 weeks) trimester and 4 weeks postpartum with the Edinburgh Postnatal Depression Scale-Korean. The prevalence of depression in the prenatal and postpartum period ranged from 40.5% to 61.4%. Depression in the second and the third trimester was significantly correlated with depression in the postpartum period. Unemployment and household income were risk factors for prenatal depression in the first and second trimesters. To assist women suffering from postpartum depression and prevent its effects, women should be screened for prenatal depression during all three trimesters. For Korean women with high risk factors for prenatal depression, we suggest that the Korean government establish healthcare policies related to depression screening as routine prenatal care and mental health referral systems.

Depressive disorders are common among the very old, but insufficiently studied. The present study aims to identify risk factors for depressive disorders in very old age. The present study is based on the GERDA project, a population-based cohort study of people aged ≥85 years (n = 567), with 5 years between baseline and follow-up. Factors associated with the development of depressive disorders according to DSM-IV criteria at follow-up were analysed by means of a multivariate logistic regression. At baseline, depressive disorders were present in 32.3 % of the participants. At follow-up, 69 % of those with baseline depressive disorders had died. Of the 49 survivors, 38 still had depressive disorders. Of the participants without depressive disorders at baseline, 25.5 % had developed depressive disorders at follow-up. Baseline factors independently associated with new cases of depressive disorders after 5 years were hypertension, a history of stroke and 15-item Geriatric Depression Scale score at baseline. The present study supports the earlier findings that depressive disorders among the very old are common, chronic and malignant. Mild depressive symptoms as indicated by GDS-15 score and history of stroke or hypertension seem to be important risk factors for incident depressive disorders in very old age.

SUMMARY Ninety subjects consisting of 30 patients of generalized anxiety disorder, 30 of dysthymic disorder (depressive neurosis) according to D. S. M. III criteria and 30 patients of mixed anxiety-depressive disorder were given a detailed psychiatric examination, in addition, they were administered the Humilton rating scales for anxiety and depression, and also the Taylor manifest anxiety scale and Amritsar depressive inventory. All the symptoms elicited were then subjected to factor analysis, five factors were isolated-two of them co-relating with the depressive rating scales and three with the anxiety rating scales. However there was considerable overlap with anxious mood having highest loading on the depressive factor. Thus anxiety and depression could not be isolated as distinct entities factorially.

Due to a dearth of research on depressive symptoms in Malaysia, particularly in Malay women, a community study was conducted to examine the prevalence and factors associated with current depressive symptoms in rural and urban Malay women with low socioeconomic status. Four hundred eighty-seven women (N rural = 242, N urban = 245) were interviewed. Information on socio-demographic variables, potential risk factors (family history of mental health problems, lifetime major depressive symptoms, and current life stressors), and current depressive symptoms (measured by the Centre for Epidemiologic Studies Depression Scale, CES-D) was collected. The prevalence of current depressive symptoms (CES-D scores > or = 16) reported was 34.5%, while the prevalence of lifetime major depressive symptoms was 27.5%. A significantly higher rate of current depressive symptoms was observed in urban women compared to rural women, chi(2) (1, N = 487) = 3.99, p < .05. However, no significant difference was found in the two groups of women in the prevalence of lifetime major depressive symptoms. The results of the multiple hierarchical regression analysis indicated that three potential factors (family history of mental health problems, lifetime major depressive symptoms, and current life stressors) were positively associated with current depressive symptoms, accounting for 17.8% of the variance, over and above the socio-demographic variables. The prevalence of depressive symptoms reported in the study was comparable to past studies. Among the factors associated with current depressive symptoms, the single most important was lifetime major depressive symptoms, followed by current life stressors, and family history of mental health problems. Among the socio-demographic variables used, perceived health status was the most important. The factors associated with depressive symptoms found in this study are consistent with past findings in the West, implying the universality of the phenomenon and common factors related to depressive symptoms in women.

Adolescent depression is common and has become a major public health concern in China, yet little research has examined the etiology of depression in Chinese adolescents. In the present study, genetic and environmental influences on Chinese adolescent depressive symptoms were investigated in 1181 twin pairs residing in Beijing, China (ages 11 to 19 years). Child- and parent-versions of the Children’s Depression Inventory (CDI) were used to measure adolescents’ depressive symptoms. For self-reports, genetic factors, shared environmental factors, and non-shared environmental factors accounted for 50%, 5%, and 45% of the variation in depressive symptoms, respectively; for parent-reports, genetic factors, shared environmental factors, and non-shared environmental factors accounted for 51%, 18%, and 31% of the variation, respectively. These estimates are generally consistent with previous findings in Western adolescents, supporting the cross-cultural generalizability of etiological model of adolescent depression. Neither qualitative nor quantitative sex differences were found in the etiological model. Future studies are needed to investigate how genes and environments work together (gene-environment interaction, gene-environment correlation) to influence depression in Chinese adolescents.

To examine factors increasing the risk for onset and persistence of subthreshold mania and depression. In a prospective cohort community study, the association between risk factors [a family history of mood disorders, trauma, substance use, attention-deficit/hyperactivity disorder (ADHD) and temperamental/personality traits] and onset of manic/depressive symptoms was determined in 705 adolescents. The interaction between baseline risk factors and baseline symptoms in predicting 8-year follow-up symptoms was used to model the impact of risk factors on persistence. Onset of manic symptoms was associated with cannabis use and novelty seeking (NS), but NS predicted a transitory course. Onset of depressive symptoms was associated with a family history of depression. ADHD and harm avoidance (HA) were associated with persistence of depressive symptoms, while trauma and a family history of depression predicted a transitory course. Different risk factors may operate during onset and persistence of subthreshold mania and depression. The differential associations found for mania and depression dimensions suggest partly different underlying mechanisms.

We examined depression within a multidimensional framework consisting of genetic, environmental, and sociobehavioral factors and, using machine learning algorithms, explored interactions among these factors that might better explain the etiology of depressive symptoms. We measured current depressive symptoms using the Center for Epidemiologic Studies Depression Scale (n = 6378 participants in the Wisconsin Longitudinal Study). Genetic factors were 78 single nucleotide polymorphisms (SNPs); environmental factors-13 stressful life events (SLEs), plus a composite proportion of SLEs index; and sociobehavioral factors-18 personality, intelligence, and other health or behavioral measures. We performed traditional SNP associations via logistic regression likelihood ratio testing and explored interactions with support vector machines and Bayesian networks. After correction for multiple testing, we found no significant single genotypic associations with depressive symptoms. Machine learning algorithms showed no evidence of interactions. Naïve Bayes produced the best models in both subsets and included only environmental and sociobehavioral factors. We found no single or interactive associations with genetic factors and depressive symptoms. Various environmental and sociobehavioral factors were more predictive of depressive symptoms, yet their impacts were independent of one another. A genome-wide analysis of genetic alterations using machine learning methodologies will provide a framework for identifying genetic-environmental-sociobehavioral interactions in depressive symptoms.

  The objective of this study is to examine relationships of hardiness and big five personality factors to depression, perceived stress, and oral lichen planus (OLP) severity. Sixty Iranian patients with oral lichen planus completed measures of perceived stress, hardiness, big five, and depression. Linear regressions revealed that control and challenge significantly predicted least perceived stress. On the contrary, big five factor of neuroticism predicted more perceived stress. Furthermore, control, commitment, and extraversion negatively predicted depression levels, but neuroticism positively predicted depression levels. Additionally, more levels of the challenge factor predicted fewer OLP scores while more levels of perceived stress predicted more OLP scores. The components of control challenge and neuroticism factors had a significant role in predicting perceived stress. On the other hand, the components of control and commitment and extraversion factors had a prominent role in predicting depression in patients with OLP, so personality constructs may have an effective role in triggering experience of stress, depression, and OLP itself. Additionally, interventions that enhance individual protective factors may be beneficial in reducing stress and depression in some severe diseases.

The Analytical Diffusion-Expansion Model for Forbush Decreases Caused by Flux Ropes

Identification and tracking of interplanetary coronal mass ejections (ICMEs) throughout the heliosphere is a growingly important aspect of space weather research. One of the "signatures" of ICME passage is the corresponding Forbush decrease (FD), a short term decrease in the galactic cosmic ray flux. These depressions are observed at the surface of the Earth for over 50 years, by several spacecraft in interplanetary space in the past couple of decades, and recently also on Mars' surface with Curiosity rover. In order to use FDs as ICME signatures efficiently, it is important to model ICME interaction with energetic particles by taking into account ICME evolution and constraining the model with observational data. We present an analytical diffusion-expansion FD model ForbMod which is based on the widely used approach of the initially empty, closed magnetic structure (i.e. flux rope) which fills up slowly with particles by perpendicular diffusion. The model is restricted to explain only the depression caused by the magnetic structure of the ICME and not of the associated shock. We use remote CME observations and a 3D reconstruction method (the Graduated Cylindrical Shell method) to constrain initial and boundary conditions of the FD model and take into account CME evolutionary properties by incorporating flux rope expansion. Several options of flux rope expansion are regarded as the competing mechanism to diffusion which can lead to different FD characteristics. This project has received funding from the European Union's Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 745782.

Evidence regarding the role of risk factors in the longitudinal course of suicidal ideation among young adolescents is lacking. We aimed to assess the effects of a range of risk factors, including obesity, academic performance, child-parent relationship, physical maltreatment, and depressive symptoms, on the development of suicidal ideation in young adolescents. A school cohort of seventh and eighth graders was followed for 1 year and differences in the risk factors distributions were examined between depressed and non-depressed adolescents. We further examined risk factors for newly developed suicidal ideation and persistent suicidal ideation in the groups of adolescents based on the presence of suicidal ideation at baseline. A total of 1710 young adolescents were recruited, among whom 8.2% were categorised as having clinically significant depression. For depressed adolescents, being obese was associated with a three-fold increased risk of having suicidal ideation. For non-depressed adolescents, physical maltreatment, a feeling of not being cared about and sub-threshold depressive symptoms were the risk factors. The latter two remained robust in predicting newly developed suicidal ideation. The current study may shed light on the differential strategies to address suicidal thoughts in depressed and non-depressed adolescents. We emphasise the importance of recognition and management of sub-threshold depressive symptoms and the relevance of obesity, physical maltreatment and a feeling of not being cared about to suicide prevention programmes in early adolescence.

Study Objectives: (1) To describe the prevalence of and risk factors for postpartum maternal sleep problems and depressive symptoms simultaneously, (2) identify factors independently associated with either condition, and (3) explore associations between specific postpartum sleep components and depression. Design: Cross-sectional. Setting: Population-based. Participants: All women (n = 4191) who had delivered at Stavanger University Hospital from October 2005 to September 2006 were mailed a questionnaire seven weeks postpartum. The response rate was 68% (n = 2830). Interventions: None. Measurements and results: Sleep was measured using the Pittsburgh Sleep Quality Index (PSQI), and depressive symptoms using the Edinburgh Postnatal Depression Scale (EPDS). The prevalence of sleep problems, defined as PSQI > 5, was 57.7%, and the prevalence of depression, defined as EPDS ≥ 10, was 16.5%. The mean self-reported nightly sleep duration was 6.5 hours and sleep efficiency 73%. Depression, previous sleep problems, being primiparous, not exclusively breastfeeding, or having a younger or male infant were factors associated with poor postpartum sleep quality. Poor sleep was also associated with depression when adjusted for other significant risk factors for depression, such as poor partner relationship, previous depression, depression during pregnancy and stressful life events. Sleep disturbances and subjective sleep quality were the aspects of sleep most strongly associated with depression. Conclusions: Poor sleep was associated with depression independently of other risk factors. Poor sleep may increase the risk of depression in some women, but as previously known risk factors were also associated, mothers diagnosed with postpartum depression are not merely reporting symptoms of chronic sleep deprivation.

Identify depression symptoms during active late-life depression (LLD) that predict conversion to dementia. The authors followed a cohort of 290 participants from the Neurocognitive Outcomes of Depression in the Elderly study. All participants were actively depressed and cognitively normal at enrollment. Depression symptom factors were derived from prior factor analysis: anhedonia and sadness, suicidality and guilt, appetite and weight loss, sleep disturbance, and anxiety and tension. Cox regression analysis modeled time to Alzheimer disease (AD) and non-AD dementia onset on depression symptom factors, along with age, education, sex, and race. Significant dementia predictors were tested for interaction with age at depression onset. Higher scores on the appetite and weight loss symptom factor were associated with an increased hazard of both AD and non-AD dementia. This factor was moderated by age at first depression onset, such that higher scores were associated with higher risk of non-AD dementia when depression first occurred earlier in life. Other depression symptom factors and overall depression severity were not related to risk of AD or non-AD dementia. Results suggest greater appetite/weight loss symptoms in active episodes of LLD are associated with increased likelihood of AD and non-AD dementia, but possibly via different pathways moderated by age at first depression onset. Results may help clinicians identify individuals with LLD at higher risk of developing AD and non-AD dementia and design interventions that reduce this risk. Copyright © 2016.

Depressed inpatients constitute a high-risk population for suicide attempts. To describe the interactions of clinical and psychosocial risk factors influencing suicide attempts among a Malaysian sample of depressed inpatients. Seventy-five subjects were diagnosed with a depressive disorder according to the Structured Clinical Interview for DSM-IV Axis I Disorders-Clinical Version (SCID-CV). Data on suicide attempts, suicidal ideation (Scale for Suicidal Ideation, SSI), depression severity (Beck's Depression Inventory, BDI), recent life-event changes (Social Readjustment Rating Scale, SRRS), sociodemographic and other relevant clinical factors were collected. A third of the subjects presented after a current suicide attempt. Significant factors for a current suicide attempt were race, religion, recent life-event changes, suicidal ideation, and alcohol use disorder. Independent predictive risk factors for a current suicide attempt were Chinese race, recent marital separation, major mortgage or loans, and being newly diagnosed with depression. Any recent change in personal habits was shown to be a protective factor against current suicide attempt. Age and gender were nonsignificant factors. The findings are generally consistent with existing studies and highlight the role of psychosocial risk factors.

It is unclear about the change and risk factors of depression among adolescent survivors after earthquake. This study aimed to explore the change of depression, and identify the predictive factors of depression among adolescent survivors after the 2008 Wenchuan earthquake in China. The depression among high school students at 6, 12 and 18 months after the Wenchuan earthquake were investigated. The Beck Depression Inventory (BDI) was used in this study to assess the severity of depression. Subjects included 548 student survivors in an affected high school. The rates of depression among the adolescent survivors at 6-, 12- and 18-month after the earthquake were 27.3%, 42.9% and 33.3%, respectively, for males, and 42.9%, 61.9% and 53.4%, respectively, for females. Depression symptoms, trauma-related self-injury, suicidal ideation and PTSD symptoms at the 6-month follow-up were significant predictive factors for depression at the 18-month time interval following the earthquake. This study highlights the need for considering disaster-related psychological sequela and risk factors of depression symptoms in the planning and implementation of mental health services. Long-term mental and psychological supports for victims of natural disasters are imperative.

Rumination, anxiety, depressive symptoms and subsequent depression in adolescents at risk for psychopathology: a longitudinal cohort study.

A ruminative style of responding to low mood is associated with subsequent high depressive symptoms and depressive disorder in children, adolescents and adults. Scores on self-report rumination scales correlate strongly with scores on anxiety and depression symptom scales. This may confound any associations between rumination and subsequent depression. Our sample comprised 658 healthy adolescents at elevated risk for psychopathology. This study applied ordinal item (non-linear) factor analysis to pooled items from three self-report questionnaires to explore whether there were separate, but correlated, constructs of rumination, depression and anxiety. It then tested whether rumination independently predicted depressive disorder and depressive symptoms over the subsequent 12 months, after adjusting for confounding variables. We identified a single rumination factor, which was correlated with factors representing cognitive symptoms of depression, somatic symptoms of depression and anxiety symptoms; and one factor representing adaptive responses to low mood. Elevated rumination scores predicted onset of depressive disorders over the subsequent year (p = 0.035), and levels of depressive symptoms 12 months later (p < 0.0005), after adjustment for prior levels of depressive and anxiety symptoms. High rumination predicts onset of depressive disorder in healthy adolescents. Therapy that reduces rumination and increases distraction/problem-solving may reduce onset and relapse rates of depression.

Few studies have investigated depression among Alaska Native people (ANs). Depression prevalence and associated factors among EARTH Alaska study participants are described. The nine-item Patient Health Questionnaire (PHQ-9) assessed depression among 3771 ANs. Participants with PHQ-9 scores≥10 out of 27 were classified as positive for depression. Logistic regression analyses evaluated odds of scoring positive versus negative for depression by demographic, cultural, then health and lifestyle factors. Twenty percent of women and 13% of men scored positive for depression. Univariate and multivariate models were fit separately for men and women. Among demographic factors, below median income was associated with positive depression scores for both genders. Among men, odds of depression were higher if unmarried and/or if highest educational level was less than high school. Women 34 to 59 years of age had increased odds of scoring positive. Little or no identification with tribal tradition was associated with increased odds of depression in women and decreased odds in men. For both genders, chronic physical conditions and poorer self-reported health were associated with positive depression scores then binge alcohol drinking and current tobacco use increased odds of depression among women only. Factors analyzed were self-reported without clinician follow-up in a non-random convenience sample of adults. Depression is common among ANs with rates comparable to other indigenous cross-sectional investigations. Depression is associated with lower income and poorer physical health. Prevention and intervention efforts should consider gender as other associated factors varied between men and women. Copyright © 2011 Elsevier B.V. All rights reserved.

The aims of this study are: to analyze the factor structure of the EURO-D depression scale; to explore the variables associated with depressive symptoms in the total sample and in the EURO-D factors; and to compare the presence of depressive symptoms and the factor distribution in 15 European countries. 62,182 participants in Wave 5 (2013) of the Survey of Health, Aging and Retirement in Europe (SHARE) were included. The SHARE study and the EURO-D scale. Factor, bivariate and multilevel analyses were performed. Higher levels of depressive symptoms were associated with a poorer self-perception of physical health (η 2 = 0.22) and economic difficulties (η 2 = 0.07). Factor analysis of the EURO-D identified two factors: Suffering and Motivation. Higher levels of depressive symptoms were associated with female gender and younger age (≤60) in the Suffering factor, and with less activity and exercise, older age (≥71), widowhood and lower educational level in the Motivation factor. Poorer self-perception of physical health and economic difficulties were associated with higher depressive symptomatology in both factors. Poorer self-perception of physical health, female gender, economic difficulties, widowhood, lower levels of activity and exercise and lower educational level were associated with higher depressive symptomatology. In the countries of southern Europe, the Motivation factor predominated.

We have made heat capacity measurements of superfluid He-4 at temperatures very close to the lambda point, T(sub lambda) , in a constant heat flux, Q, when the helium sample is heated from above. In this configuration the helium enters a self-organized (SOC) heat transport state at a temperature T(sub SOC)(Q), which for Q greater than or = 100 nW/sq cm lies below T(sub lambda). At low Q we observe little or no deviation from the bulk Q = 0 heat capacity up to T(sub SOC)(Q); beyond this temperature the heat capacity appears to be sharply depressed, deviating dramatically from its bulk behaviour. This marks the formation and propagation of a SOC/superfluid two phase state, which we confirm with a simple model. The excellent agreement between data and model serves as an independent confirmation of the existence of the SOC state. As Q is increased (up to 6 micron W/sq cm) we observe a Q dependant depression in the heat capacity that occurs just below T(sub SOC)(Q), when the entire sample is still superfluid. This is due to the emergence of a large thermal resistance in the sample, which we have measured and used to model the observed heat capacity depression. Our measurements of the superfluid thermal resistivity are a factor of ten larger than previous measurements by Baddar et al.

The objectives of this study were: (1) to describe the prevalence and 6-month incidence of observer-rated depression in residents age 65 and over of long-term care (LTC) facilities; (2) to describe risk factors for depression, at baseline and over time. A multisite, prospective observational study was conducted in residents aged 65 and over of 7 LTC facilities. The Cornell Scale for Depression in Dementia (CSDD) was completed by nurses monthly for 6 months. We measured demographic, medical, and functional factors at baseline and monthly intervals, using data from research assessments, nurse interviews, and chart reviews. 274 residents were recruited and completed baseline depression assessments. The prevalence of depression (CSDD score of 6+) was 19.0%. The incidence of depression among those without prevalent depression was 73.3 per 100 person-years. A delirium diagnosis, pain, and diabetes were independently associated with prevalent depression. CSDD score at baseline and development of severe cognitive impairment at follow-up were independent risk factors for incident depression. A diagnosis of delirium and uncorrected visual impairment at follow-up occurred concurrently with incident depression. The results of this study have implications for the detection and prevention of depression in LTC. Delirium diagnosis, pain and diabetes at baseline were associated with prevalent depression; depression symptoms at baseline and development of severe cognitive impairment at follow-up were risk factors for incident depression.

Study aims were to identify subgroups of adolescents with elevated depressive symptoms who had the highest likelihood of developing future major/minor depressive disorder on the basis of depression risk factors and participation in three depression prevention programs, with the goal of evaluating the preventive effect of indicated prevention interventions in the context of known risk factors. Adolescents (N = 341) with elevated depressive symptoms were randomized to one of four prevention intervention conditions (cognitive-behavioral group, supportive-expressive group, cognitive-behavioral bibliotherapy, educational brochure control). By 2-year follow-up, 14% showed onset of major/minor depressive disorders. Classification tree analysis (CTA) revealed that negative attributional style was the most important risk factor: youth with high scores showed a 4-fold increase in depression onset compared to youth who did not endorse this attributional style. For adolescents with negative attributional style, prevention condition emerged as the most important predictor: those receiving bibliotherapy showed a 5-fold reduction in depression disorder onset relative to adolescents in the three other intervention conditions. For adolescents who reported low negative attributional style scores, elevated levels of depressive symptoms at baseline emerged as the most potent predictor. Results implicate two key pathways to depression involving negative attributional style and elevated depressive symptoms in this population, and suggest that bibliotherapy may offset the risk conveyed by the most important depression risk factor in this sample.

Homosexuality is a recognized risk factor for depression in high-income countries; however, there is little research investigating the relationship between depression and sexual orientation in developing countries, especially in Africa. In this first study to investigate psychopathology in sexual minority men in Nigeria, the prevalence rates of depression in Nigerian gay and heterosexual individuals were compared as well as the explanatory power of risk and resilience factors in both groups. Eighty-one gay and 81 heterosexual male university students were, respectively, recruited from the Obafemi Awolowo University. Both groups were assessed for depression and other clinical factors, including alcohol and other substance use, suicidal ideation, and resilience. Gay students were further assessed for sexuality-related variables, including minority stress factors such as internalized homophobia and perceived stigma. The prevalence rates of depression among gay and heterosexual students were, respectively, 16 and 4.9% (OR 3.7; 95% CI 1.15-11.82), and this increased likelihood for depression was significantly attenuated by resilience. Clinical factors correlated significantly with depression in both groups, explaining 31% of the variance in depression in gay and heterosexual students, respectively. Sexuality-related variables including internalized homophobia and perceived stigma were further associated with depression in gay students-accounting for a further 14% of the variance of depression in gay students. The findings highlight the importance of minority stress factors in understanding depression among non-heterosexual individuals in a developing country, and the need for further research to investigate the mechanisms of these relationships in such settings.

This study was based on social-role theory, and purposes were to investigate (1) how depression and health determinants vary with married and employed women, and (2) what factors contribute to depression according to family cycle. A stratified convenience sample of 765 married and employed women was recruited during May to August 2010. Study variables of depression, socio-demographic threatening factors, psycho-stimulating factors, and social-role related factors were measured via a structured questionnaire. Prevalence rate for depression was 18.6%, with highest rate (25.4%) from elementary laborers. Greater levels of depression were related to women's occupation, higher life stress, and poorer health; lower social support and vulnerable personality; higher levels of social-role related stress. From multivariate analysis, women with preadolescents were the most vulnerable to depression affected by occupation, life stress, personality, and parenting stress. These factors (except for occupational class) combined with economic status, social support, and housework unfairness were significant for depression in women with adolescents. Depression among married and employed women differs by psycho-stimulating and social role relevant factors in addition to occupational class and family life cycle. Female elementary laborers and women with children need to have the highest prioritization for community mental health programs.

For mental health outreach programs for older adults, accurately detecting depression is key to quality service provision. Multiple factors, including gender, cognitive impairment, or recent bereavement may affect depression detection, but this is under-studied. Therefore, we sought to both establish rates of depressive symptom detection and to examine factors associated with inaccuracies of detecting depression among participants in a mental health outreach program serving older adults. We conducted a chart review of 1126 cases in an older adult-focused mental health outreach program in New Hampshire, the Referral Education Assistance & Prevention (REAP) program. Accuracy of depression detection was identified by comparing screen-positive scores for depressive symptoms on the 15-item Geriatric Depression Scale (GDS) to depression identification by counselors on a 'presenting concerns' list. Inaccurate depression detection (positive on the GDS but depression not identified by counselors) occurred in 27.6% of cases. Multivariate regression analyses indicated that anxiety, cognitive concerns, and rurality were all associated with detection innaccuracy. This study appears to be the first to examine factors influencing depression detection in a mental health outreach program. Future efforts should help ensure that all older mental health outreach clients have depression detected at optimal rates.

We examined the relationship between a remote history of concussions with current symptoms of depression in retired professional athletes. Thirty retired National Football League (NFL) athletes with a history of concussion and 29 age- and IQ-matched controls without a history of concussion were recruited. We found a significant correlation between the number of lifetime concussions and depressive symptom severity using the Beck Depression Inventory II. Upon investigating a three-factor model of depressive symptoms (affective, cognitive, and somatic; Buckley et al., 2001) from the BDI-II, the cognitive factor was the only factor that was significantly related to concussions. In general, NFL players endorsed more symptoms of depression on all three Buckley factors compared with matched controls. Findings suggest that the number of self-reported concussions may be related to later depressive symptomology (particularly cognitive symptoms of depression).

This study was designed to investigate associations among five factor personality traits, perceived stress, and depressive symptoms and to examine the roles of personality and perceived stress in the relationship between gender and depressive symptoms. The participants (N = 3,950) were part of a cohort study for health screening and examination at the Kangbuk Samsung Hospital. Personality was measured with the Revised NEO Personality Inventory (NEO-PI-R). Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Perceived stress level was evaluated with a self-reported stress questionnaire developed for the Korea National Health and Nutrition Examination Survey. A higher degree of neuroticism and lower degrees of extraversion, agreeableness, and conscientiousness were significantly associated with greater perceived stress and depressive symptoms. Neuroticism and extraversion had significant direct and indirect effects (via stress as a mediator) on depressive symptoms in both genders. Agreeableness and conscientiousness had indirect effects on depression symptoms in both genders. Multiple mediation models were used to examine the mediational roles of each personality factor and perceived stress in the link between gender and depressive symptoms. Four of the personality factors (except openness) were significant mediators, along with stress, on the relationship between gender and depressive symptoms. Our findings suggest that the links between personality factors and depressive symptoms are mediated by perceived stress. As such, personality is an important factor to consider when examining the link between gender and depression. PMID:27120051

Internet addiction (IA) is a risk factor while some psychosocial factors can be protective against depression among adolescents. Mechanisms of IA onto depression in terms of mediations and moderations involving protective factors are unknown and were investigated in this study. A representative cross-sectional study was conducted among Hong Kong Chinese secondary school students (n=9518). Among males and females, prevalence of depression at moderate or severe level (CES-D≥21) was 38.36% and 46.13%, and that of IA (CIAS>63) was 17.64% and 14.01%, respectively. Adjusted for socio-demographics, depression was positively associated with IA [males: adjusted odds ratio (AOR)=4.22, 95% CI=3.61-4.94; females: AOR=4.79, 95% CI=3.91-5.87] and negatively associated with psychosocial factors including self-esteem, positive affect, family support, and self-efficacy (males: AOR=0.76-0.94; females: AOR=0.72-0.92, p<.05). The positive association between IA and depression was partially mediated by the protective psychosocial factors (mainly self-esteem) across sexes. Through significant moderations, IA also reduced magnitude of protective effects of self-efficacy and family support among males and that of positive affect among both sexes against depression. The high IA prevalence contributes to increased risk of prevalent depression through its direct effect, mediation (reduced level of protective factors) and moderation (reduced magnitude of protective effects) effects. Understanding to mechanisms between IA and depression through protective factors is enhanced. Screening and interventions for IA and depression are warranted, and should cultivate protective factors, and unlink negative impact of IA onto levels and effects of protective factors.

Little is known about depression-anxiety comorbidity and its association with personality traits and suicide/self-harm in adult psychiatric inpatients with serious mental illness (SMI), impacting clinical assessment and treatment. This study sought to determine the symptom structure of depression-anxiety comorbidity and its relation to neuroticism, extraversion, and suicide/self-harm behaviour in this high-risk population. Nine hundred and sixty-two adults receiving inpatient care at a private psychiatric hospital completed questionnaires at admission. Confirmatory factor analyses compared a bifactor solution specifying a general distress factor and two specific depression and anxiety factors against unidimensional and correlated factors solutions. The bifactor solutions' factors were subsequently correlated with neuroticism and extraversion subscales and pre-hospitalization suicide/self-harm behaviours. The bifactor model rendered superior fit to sample data and a robust general factor - accounting for 77.61% of common item variance - providing the first evidence for a tripartite structure of depression and anxiety among adult inpatients. The bifactor solution-outputted independent general distress, depression, and anxiety factors positively correlated with neuroticism, the personality dimension corresponding to trait negative affectivity. The general distress and depression factors associated with recent self-harm, but factors showed no associations with prior suicidal behaviour. In adult psychiatric inpatients, general distress substantially underlies comorbid depression and anxiety symptom variation and may contribute to recent incidence of self-harm. Transdiagnostic assessments and interventions targeting general distress may temper depression, anxiety, and self-harm in adult inpatients. Clinical implications Depression-anxiety comorbidity symptomology in adult psychiatric inpatients is primarily composed of general distress. General distress and specific depression are associated with recent self-harm but not suicidal behaviour. Assessing and treating general distress rather than depression or anxiety specifically may best mitigate comorbid depression and anxiety, and reduce self-harm behaviour in this clinical population. Cautions and limitations The large sample lacked ethnocultural diversity, and data were cross-sectional. The use of brief self-report measures to assess depression and anxiety may have reduced measurement range. © 2015 The British Psychological Society.

Brain-derived neurotrophic factor is implicated in the pathophysiology of major depressive disorder and suicide. Both are partly caused by early life adversity, which reduces brain-derived neurotrophic factor protein levels. This study examines the association of brain-derived neurotrophic factor Val66Met polymorphism and brain brain-derived neurotrophic factor levels with depression and suicide. We hypothesized that both major depressive disorder and early life adversity would be associated with the Met allele and lower brain brain-derived neurotrophic factor levels. Such an association would be consistent with low brain-derived neurotrophic factor mediating the effect of early life adversity on adulthood suicide and major depressive disorder. Brain-derived neurotrophic factor Val66Met polymorphism was genotyped in postmortem brains of 37 suicide decedents and 53 nonsuicides. Additionally, brain-derived neurotrophic factor protein levels were determined by Western blot in dorsolateral prefrontal cortex (Brodmann area 9), anterior cingulate cortex (Brodmann area 24), caudal brainstem, and rostral brainstem. The relationships between these measures and major depressive disorder, death by suicide, and reported early life adversity were examined. Subjects with the Met allele had an increased risk for depression. Depressed patients also have lower brain-derived neurotrophic factor levels in anterior cingulate cortex and caudal brainstem compared with nondepressed subjects. No effect of history of suicide death or early life adversity was observed with genotype, but lower brain-derived neurotrophic factor levels in the anterior cingulate cortex were found in subjects who had been exposed to early life adversity and/or died by suicide compared with nonsuicide decedents and no reported early life adversity. This study provides further evidence implicating low brain brain-derived neurotrophic factor and the brain-derived neurotrophic factor Met allele in major depression risk. Future studies should seek to determine how altered brain-derived neurotrophic factor expression contributes to depression and suicide.

Data on risk factors for major antenatal depression among African American women are scant. In this study, we seek to determine the prevalence and risk factors for major antenatal depression among low-income African American women receiving prenatal services through the Central Hillsborough Healthy Start (CHHS). Women were screened using the Edinburgh Postnatal Depression Scale (EPDS) with a cutoff of > or =13 as positive for risk of major antenatal depression. In total, 546 African American women were included in the analysis. We used logistic regression to identify risk factors for major antenatal depression. The prevalence of depressive symptomatology consistent with major antenatal depression was 25%. Maternal age was identified as the main risk factor for major antenatal depression. The association between maternal age and risk for major antenatal depression was biphasic, with a linear trend component lasting until age 30, at which point the slope changed markedly tracing a more pronounced likelihood for major depression with advancing age. Women aged > or =30 were about 5 times as likely to suffer from symptoms of major antenatal depression as teen mothers (OR = 4.62, 95% CI 2.23-9.95). The risk for major antenatal depression increases about 5-fold among low-income African American women from age 30 as compared to teen mothers. The results are consistent with the weathering effect resulting from years of cumulative stress burden due to socioeconomic marginalization and discrimination. Older African American mothers may benefit from routine antenatal depression screening for early diagnosis and intervention.

Depression and burnout are frequent comorbidities among nurses. Despite similar symptoms, their management differ. Therefore, their timely diagnosis is essential. To identify demographic and work-related risk and protective factors of burnout and depression, and facilitate their diagnosis. A cross-sectional study among 1,713 nurses was carried out. Depression and burnout were assessed by the shortened Beck Depression Questionnaire and Maclach Burnout Inventory, respectively. Risk and protective factors were explored using t-tests and analysis of variance. The prevalence of depression and moderate-to-high burnout was 35.1% and 34-74%, respectively. Having a partner/child and longer employment in the outpatient setting protected from burnout. Lack of a partner and male sex emerged as risk factors of depression and depersonalisation, respectively. High prevalence of depression and burnout among nurses poses a significant public health issue. Familiarity with the disease-specific risk and protective factors identified in this research may facilitate timely diagnosis and effective disease management.

To answer the question of adequate treatment of depression in women from a scientific point of view, it is necessary to investigate the aetiology of depressive disorders as they relate to bio-genetic, mental and social factors. For a comprehensive understanding of depressive disorders in women three factors are analysed: (1) the severity of a depression, (2) the phenomenological description, and (3) the factors of the development of depression in the female life cycle. Different treatment strategies for women can be developed on the basis of these phenomenological and psychodynamic considerations. A case study of a female patient suffering from depressive adjustment disorder who had a background history of sexual reproductive problems is presented to demonstrate characteristic factors in women which may serve as indicators for psychoanalytic focal psychotherapy. In our opinion, psychoanalytic theory in its complexity, working with unconscious phantasies, fears concerning body integrity and relationships to others, is the most appropriate method to determine specific factors behind the pathogenesis and the persistence of depressive disorders in women.

Recently, there are few studies reporting on depressive status and obstructive sleep apnoea (OSA) in China. A large-sample survey was to be performed to explore the prevalence of depressive status and related factors in Chinese patients with OSA. From among a randomly-selected group of OSA patients, 1,327 met inclusion criteria. After screening with the Symptom Checklist 90 (SCL-90) and Self-Rating Depression Scale (SDS), patients were assigned to OSA without depressive status (control group, n = 698) and OSA with depressive status (n = 629) groups. Using chi-squared testing, the correlation analyses between the depressive status and OSA patient demographic and clinical variables were tested. Then depression-related risk factors in OSA patients were analysed using stepwise linear regression analysis. The effects of family and social factors on depressive status in OSA patients were investigated using Mann-Whitney U (one of nonparametric test). The prevalence of depressive status was 47.4% in OSA patients. Depressive status was significantly associated with female gender, single status, Family Burden Scale of Disease (FBS), Family APGAR Index (APGAR), apnoea-hypopnea index (AHI), and Perceived Social Support Scale (PSSS). Stepwise linear regression analysis further indicated that single status, hypoxemia, APGAR, AHI, PSSS, AHI, and FBS were all risk factors for depressive status in OSA patients. The total of the FBS score and three of its sub-factors scores (family daily activities, family relationships and mental health of family members) were higher, and the total of the APGAR score and two of its sub-factors scores (adaptability and affection) were lower in OSA with depressive status compared with the control group. Besides, the total score for the PSSS and scores for its two sub-factors (family support and social support) were all lower in OSA patients with depressive status than those of the control group. Depressive status has high comorbid rate in Chinese OSA patients and is significantly associated with single status, apnoea-hypopnea index, hypoxemia, family and social supports.

Objective To explore the relationship between family environment and depressive symptoms and to evaluate the influence of hard and soft family environmental factors on depression levels in a large sample of university students in China. Methods A multi-stage stratified sampling procedure was used to select 6,000 participants. The response rate was 88.8%, with 5,329 students completing the Beck Depression Inventory (BDI) and the Family Environment Scale Chinese Version (FES-CV), which was adapted for the Chinese population. Differences between the groups were tested for significance by the Student’s t-test; ANOVA was used to test continuous variables. The relationship between soft family environmental factors and BDI were tested by Pearson correlation analysis. Hierarchical linear regression analysis was conducted to model the effects of hard environmental factors and soft environmental factors on depression in university students. Results A total of 11.8% of students scored above the threshold of moderate depression(BDI≧14). Hard family environmental factors such as parent relationship, family economic status, level of parental literacy and non-intact family structure were associated with depressive symptoms. The soft family environmental factors—conflict and control—were positively associated with depression, while cohesion was negatively related to depressive symptom after controlling for other important associates of depression. Hierarchical regression analysis indicated that the soft family environment correlates more strongly with depression than the hard family environment. Conclusions Soft family environmental factors—especially cohesion, conflict and control—appeared to play an important role in the occurrence of depressive symptoms. These findings underline the significance of the family environment as a source of risk factors for depression among university students in China and suggest that family-based interventions and improvement are very important to reduce depression among university students.

Background Fluctuating hormone levels are known to influence a woman’s mood and well-being. This study aimed to determine whether lifetime hormonal markers are associated with late-life depression symptoms among elderly community-dwelling women. Method Detailed reproductive histories of 1013 women aged 65 years and over were obtained using questionnaires and depressive symptoms were assessed using the Centre for Epidemiological Studies Depression Scale. Multivariate logistic regression models were generated to determine whether any lifetime endogenous or exogenous hormonal factors were associated with late-life depression. Results The prevalence of depressive symptoms was 17%. Age at menopause was associated with depressive symptoms, but only among women with a lower education level. For these women, an earlier age at menopause increased their risk of late-life depression (linear effect, OR=0.95, 95%CI: 0.91–0.99). The odds of late-life depression were also increased for women who were past (OR=1.6, 95%CI: 1.1–2.5), but not current hormonal replacement users. On the other hand, long-term oral contraceptive use (≥10 years) was protective against depression (OR=0.3, 95%CI: 0.1–0.9). These associations remained significant even after extensive adjustment for a range of potential confounding factors, including socio-demographic factors, mental and physical incapacities, antidepressant use and past depression. The other factors examined, including age at first menses, parity, age at childbirth and surgical menopause, were not associated with late-life depressive symptoms. Conclusions Lifetime hormonal factors that are significantly associated with depression symptoms in later life have been identified. Further work is needed to determine how potential hormonal interventions could be used in the treatment of late-life depression in certain sub-groups of women. PMID:18533067

Rumination, anxiety, depressive symptoms and subsequent depression in adolescents at risk for psychopathology: a longitudinal cohort study

PubMed Central

2013-01-01

Background A ruminative style of responding to low mood is associated with subsequent high depressive symptoms and depressive disorder in children, adolescents and adults. Scores on self-report rumination scales correlate strongly with scores on anxiety and depression symptom scales. This may confound any associations between rumination and subsequent depression. Methods Our sample comprised 658 healthy adolescents at elevated risk for psychopathology. This study applied ordinal item (non-linear) factor analysis to pooled items from three self-report questionnaires to explore whether there were separate, but correlated, constructs of rumination, depression and anxiety. It then tested whether rumination independently predicted depressive disorder and depressive symptoms over the subsequent 12 months, after adjusting for confounding variables. Results We identified a single rumination factor, which was correlated with factors representing cognitive symptoms of depression, somatic symptoms of depression and anxiety symptoms; and one factor representing adaptive responses to low mood. Elevated rumination scores predicted onset of depressive disorders over the subsequent year (p = 0.035), and levels of depressive symptoms 12 months later (p < 0.0005), after adjustment for prior levels of depressive and anxiety symptoms. Conclusion High rumination predicts onset of depressive disorder in healthy adolescents. Therapy that reduces rumination and increases distraction/problem-solving may reduce onset and relapse rates of depression. PMID:24103296

This study examines the individual and workplace factors related to depression and stress in a large privately owned enterprise in China. The cross-sectional study design involved 13 privately owned retail enterprises in China. A self-report survey was administered to 4,847 employees aged 18-54 recruited through the management boards of the 13 enterprises. A chi-square test was used to compare differences between the depressed and non-depressed groups on a number of demographic variables and chronic diseases. Logistic regression analysis was performed to assess depression in relation to individual factors (work ability and resilience) and organisational environmental factors (workplace ethos and culture, psychosocial environment and health promotion policies and activities). Significant relationships were found between employee depression all personal factors, and one organisational environmental factor. Personal factors include poor work ability and low resilience, while workplace factors include workplace ethos and culture. The primary organisational environmental factor was a low level of enterprise ethos and culture.

We investigated the association between old age depression and emotional and social loneliness. A cross-sectional study was performed using data from the Netherlands Study of Depression in Older Persons (NESDO). A total of 341 participants diagnosed with a depressive disorder, and 125 non-depressed participants were included. Depression diagnosis was confirmed with the Composite International Diagnostic Interview. Emotional and social loneliness were assessed using the De Jong Gierveld Loneliness Scale. Socio-demographic variables, social support variables, depression characteristics (Inventory of Depressive Symptoms), cognitive functioning (Mini Mental State Examination) and personality factors (the NEO- Five Factor Inventory and the Pearlin Mastery Scale) were considered as possible explanatory factors or confounders. (Multiple) logistic regression analyses were performed. Depression was strongly associated with emotional loneliness, but not with social loneliness. A higher sense of neuroticism and lower sense of mastery were the most important explanatory factors. Also, we found several other explanatory and confounding factors in the association of depression and emotional loneliness; a lower sense of extraversion and higher severity of depression. We performed a cross-sectional observational study. Therefore we cannot add evidence in regard to causation; whether depression leads to loneliness or vice versa. Depression in older persons is strongly associated with emotional loneliness but not with social loneliness. Several personality traits and the severity of depression are important in regard to the association of depression and emotional loneliness. It is important to develop interventions in which both can be treated. Copyright © 2015 Elsevier B.V. All rights reserved.

The objective of this study was to find risk factors in pregnancy for post-traumatic stress and depression 1 month after childbirth. Furthermore, the relation between post-traumatic stress and depression was explored. A prospective longitudinal study. Pregnant women in Linköping and Kalmar, Sweden. A total of 1224 women were assessed in pregnancy, week 12-20 and 32, as well as 1 month postpartum. Post-traumatic stress and depression after delivery were assessed 1 month postpartum. Potential risk factors were assessed in early and late pregnancy. Variables measured during pregnancy were trait anxiety, depression, fear of childbirth, childbirth-related traumatic stress, stress coping capacity, social support, parity, educational level, age, gestation week, parity, educational level, civil status, previous psychological/psychiatric counselling, and previous experience of any traumatic events. Delivery mode was assessed from the medical records. Prevalence of post-traumatic stress (criteria A, B, C, D, E, and F according to DSM-IV) and depression (Beck's depression inventory). One month postpartum, 12 (1.3%) women had post-traumatic stress (met symptom criteria B, C, and D for post-traumatic stress disorder according to Diagnostic and statistical manual of mental disorders, 4th edition [DSM-IV]). The most important risk factors in pregnancy were depression in early pregnancy (OR=16.3), severe fear of childbirth (OR=6.2), and 'pre'-traumatic stress (in view of the forthcoming delivery) in late pregnancy (OR=12.5). The prevalence of depression was 5.6%. Post-traumatic stress and depression were positively related 1 month postpartum and were predicted by mainly the same factors. Risk factors for post-traumatic stress and depression after childbirth can be assessed in early pregnancy. Post-traumatic stress and depression also seem to share the same underlying vulnerability factors.

Examining overgeneral autobiographical memory as a risk factor for adolescent depression.

Rawal, Adhip; Rice, Frances

2012-05-01

Identifying risk factors for adolescent depression is an important research aim. Overgeneral autobiographical memory (OGM) is a feature of adolescent depression and a candidate cognitive risk factor for future depression. However, no study has ascertained whether OGM predicts the onset of adolescent depressive disorder. OGM was investigated as a predictor of depressive disorder and symptoms in a longitudinal study of high-risk adolescents. In addition, cross-sectional associations between OGM and current depression and OGM differences between depressed adolescents with different clinical outcomes were examined over time. A 1-year longitudinal study of adolescents at familial risk for depression (n = 277, 10-18 years old) was conducted. Autobiographical memory was assessed at baseline. Clinical interviews assessed diagnostic status at baseline and follow-up. Currently depressed adolescents showed an OGM bias compared with adolescents with no disorder and those with anxiety or externalizing disorders. OGM to negative cues predicted the onset of depressive disorder and depressive symptoms at follow-up in adolescents free from depressive disorder at baseline. This effect was independent of the contribution of age, IQ, and baseline depressive symptoms. OGM did not predict onset of anxiety or externalizing disorders. Adolescents with depressive disorder at both assessments were not more overgeneral than adolescents who recovered from depressive disorder over the follow-up period. OGM to negative cues predicted the onset of depressive disorder (but not other disorders) and depressive symptoms over time in adolescents at familial risk for depression. Results are consistent with OGM as a risk factor for depression. Copyright © 2012 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc. All rights reserved.

The purposes of this study were to identify the relationships among acculturative stress, work-related psychosocial factors and depression in Korean-Chinese migrant workers living in Korea and to determine whether work-related psychosocial factors mediate the relationship between acculturative stress and depression. A descriptive correlational cross-sectional design was used. A convenience sample of 200 Korean-Chinese full-time migrant workers was recruited, and 170 completed questionnaires were included in the analysis. Acculturative stress was assessed by Sandh and Asrabadi's Acculturative Stress Scale. Work-related psychosocial factors were assessed by job demand, insufficient job control and interpersonal conflict measures from the Korean Occupational Stress Scale. Depression was assessed by the Center for Epidemiologic Studies Depression Scale. Self-administered or face-to-face surveys were conducted by trained data collectors. Multiple regression and path analysis were used. Roughly 30% of the sample met the criteria for depression. Female workers had significantly higher depression scores than male workers. Acculturative stress and work-related psychosocial factors significantly predicted 26.3% of the variance in depression. A path model revealed the mediating effect of job demand on the relationship between acculturative stress and depression. Our results indicate that work-related psychosocial factors are salient factors that lead to depression among Korean-Chinese migrant workers living in Korea. The results suggest that occupational health-care professionals should promote the prevention and management of depression in this population and highlight the importance of acculturation context in the development of interventions designed to reduce work-related stress.

Negative mood states are composed of symptoms of depression and anxiety, and by a third factor related to stress, tension and irritability. We sought to clarify the nature of the relationships between the factors by studying twin pairs. A total of 503 monozygotic twin pairs completed the Depression Anxiety Stress Scales (DASS), an instrument that assesses symptoms of depression, anxiety and stress-tension. We applied a recently developed twin regression methodology - Inference about Causation from Examination of FAmiliaL CONfounding (ICE FALCON) - to test for evidence consistent with the existence of 'causal' influences between the DASS factors. There was evidence consistent with the stress-tension factor having a causal influence on both the depression (p < 0.0001) and anxiety factors (p = 0.001), and for the depression factor having a causal influence on the anxiety factor (p < 0.001). Our findings suggest a critical role for stress-tension in the structure of negative mood states, and that interventions that target it may be particularly effective in reducing depression and anxiety symptoms.

This study used semi-parametric group-based modeling to explore unconditional and conditional trajectories of self-reported depressed mood from age 12 to 25. Drawing on data from the National Longitudinal Study of Adolescent Health (N=11,559), four distinct trajectories were identified: no depressed mood, stable low depressed mood, early high declining depressed mood, and late escalating depressed mood. Baseline risk factors associated with greater likelihood of membership in depressed mood trajectory groups compared to the no depressed mood group included being female, Black/African American, Hispanic/Latino American, or Asian American, lower SES, using alcohol, tobacco, or other drugs on a weekly basis, and delinquent behavior. Baseline protective factors associated with greater likelihood of membership in the no depressed mood group compared to the depressed mood trajectory groups included two-parent family structure, feeling connected to parents, peers, or school, and self esteem. With the exception of delinquent behavior, risk and protective factors also distinguished the likelihood of membership among several of the three depressed mood groups. The results add to basic etiologic research regarding developmental pathways of depressed mood in adolescence and young adulthood. PMID:18377115

Depression in adolescent pregnancy is common but underrecognized and can be associated with negative medical outcomes. This brief report examines the relationship between depressive symptoms and various demographic and obstetrical risk factors, as well as the use of antidepressants in pregnant adolescents of late teenage years. Data were derived from a relatively large sample (506 women) recruited from university-based and community mental health centers in Iowa. A cross-sectional analysis did not reveal significant statistical associations between the risk factors and depressive symptoms (Beck Depression Inventory). Antidepressant use was very low (3.7 %), and adolescents with higher depression scores were more likely to take medications. In conclusion, screening for depression in pregnant adolescents should be universal, regardless of demographic and obstetrical risk factors, and promptly addressed.

Depression among the urban poor in Peninsular Malaysia: a community based cross-sectional study.

2013-01-01

This community based cross-sectional study examined the prevalence and factors associated with depression among urban poor in Peninsular Malaysia. The Patient Health Questionnaire (PHQ-9) was used to determine the presence or absence of depression. The prevalence of depression among the urban poor was 12.3%. Factors significantly associated with depression included respondents under 25 years old, male gender, living in the area for less than four years and those who do not exercise regularly. It is important to identify individuals with depression and its associated factors early because depression can severely affect the quality of life.

Depression is a common condition in adults with low back pain (LBP), and is associated with poorer patient outcomes. Social support is a modifiable factor that may influence depressive symptoms in people with LBP and, if so, could be a consideration in LBP management when depression is an issue. The aim of this study was to examine social support as a prognostic factor for depressive symptoms and recovery from depression in patients with LBP. Patients with LBP (n = 483), recruited from four imaging centers in Canada, completed an initial survey following imaging and a follow-up survey one year later, including the Medical Outcomes Study (MOS) Social Support Survey and the Center for Epidemiologic Studies Depression Scale. Multivariable regression analyses were used to examine the relationship between social support and depression. More social support (overall functional social support) at baseline was associated with recovery from depression (OR = 0.24; 95% CI 0.10, 0.55) and less depressive symptoms (β = 1.68; 95% CI = 0.36, 3.00) at one-year follow-up. In addition, associations were found between specific aspects (subscales) of social support and the two depression outcomes. Functional social support as a prognostic factor for depression and possible target of LBP management warrants further investigation. Implications for Rehabilitation Depression is a common condition in adults with low back pain (LBP), and is associated with poorer patient outcomes. This study provides evidence for social support as a prognostic factor for depressive symptoms and recovery from depression in patients with LBP problems. Management of pain conditions may be enhanced by a better understanding of modifiable risk factors for depression, such as social support.

Most disadvantaged women are exposed to risk factors for depression, but not all necessarily have an identical risk for this mental health problem. A better prediction of which low socioeconomic status (SES) women are most at risk for depressive symptoms can help target preventive interventions at high-risk subgroups most in need of support. Exploring which demographic, socioeconomic and psychological risk factors are associated with self-reported depressive symptoms in a sample of low-SES women and whether the number of risk factors might expose them to an accumulated risk. Between April 2005 and November 2007, 519 disadvantaged women from urban neighbourhoods in Maastricht, a southern Dutch city, participated in a cross-sectional survey on stress and depressive symptoms. Lower education levels, no current employment and lower net monthly family incomes were socioeconomic risk factors associated with higher scores for depressive symptoms. The psychological risk factor 'perceived stress' had the highest explained variance and was most strongly associated with depressive symptoms. Women exposed to multiple risk factors across domains had a cumulated risk for depressive symptomatology. Low-SES women who seem most eligible for targeted preventive action are those with cumulative risks. Depression prevention strategies for this population may benefit from focusing on perceived stress since this is an important modifiable risk factor. © The Author(s) 2014.

The prevalence and correlates of depression vary across countries. Contextual factors such as country-level income or income inequalities have been hypothesised to contribute to these differences. To investigate associations of depression with socioeconomic factors at the country level (income inequality, gross national income) and individual (education, employment, assets and spending) level, and to investigate their relative contribution in explaining the cross-national variation in the prevalence of depression. Multilevel study using interview data of 187 496 individuals from 53 countries participating in the World Health Organization World Health Surveys. Depression prevalence varied between 0.4 and 15.7% across countries. Individual-level factors were responsible for 86.5% of this variance but there was also reasonable variation at the country level (13.5%), which appeared to increase with decreasing economic development of countries. Gross national income or country-level income inequality had no association with depression. At the individual level, fewer material assets, lower education, female gender, economic inactivity and being divorced or widowed were associated with increased odds of depression. Greater household spending, unlike material assets, was associated with increasing odds of depression (adjusted analysis). The variance of depression prevalence attributable to country-level factors seemed to increase with decreasing economic development of countries. However, country-level income inequality or gross national income explained little of this variation, and individual-level factors appeared more important than contextual factors as determinants of depression. The divergent relationship of assets and spending with depression emphasise that different socioeconomic measures are not interchangeable in their associations with depression.

Social phobia and depression are common and highly comorbid disorders in adolescence. There is a lack of studies on possible psychosocial shared risk factors for these disorders. The current study examined if low social support is a shared risk factor for both disorders among adolescent girls and boys. This study is a part of the Adolescent Mental Health Cohort Study's two-year follow-up. We studied cross-sectional and longitudinal associations of perceived social support with social phobia, depression, and comorbid social phobia and depression among girls and boys. The study sample consisted of 2070 15-year-old adolescents at baseline. Depression was measured by the 13-item Beck Depression Inventory, social phobia by the Social Phobia Inventory (SPIN), and perceived social support by the Perceived Social Support Scale-Revised (PSSS-R). Girls reported higher scores on the PSSS-R than boys in total scores and in friend and significant other subscales. Cross-sectional PSSS-R scores were lower among adolescents with social phobia, depression, and comorbid disorder than among those without these disorders. Low PSSS-R total score and significant other subscale were risk factors for depression among both genders, and low support from friends among girls only. Low perceived social support from any source was not a risk factor for social phobia or comorbid social phobia and depression. As conclusion of the study, low perceived social support was a risk factor for depression, but not a shared risk factor for depression and social phobia. Interventions enhancing perceived social support should be an important issue in treatment of depression.

The comorbidity of major depression and substance use disorders is well documented. However, thorough understanding of prevalence and early risk factors for comorbidity in adulthood is lacking, particularly among urban African Americans. With data from the Woodlawn Study, which follows a community cohort of urban African Americans from ages 6 to 42, we identify the prevalence of comorbidity and childhood and adolescent risk factors of comorbid depression and substance use disorders, depression alone, and substance use disorders alone. Prevalence of comorbid substance use disorders and major depression in adulthood is 8.3% overall. Comorbidity in cohort men is twice that for women (11.1% vs. 5.7%). Adjusted multinomial regression models found few differences in risk factors for comorbidity compared to either major depression or a substance use disorder on its own. However, results do suggest distinct risk factors for depression without a substance use disorder in adulthood compared to a substance use disorder without depression in adulthood. In particular, low socioeconomic status and family conflict was related to increased risk of developing major depression in adulthood, while dropping out of high school was a statistically significant predictor of adult-onset substance use disorders. Early onset of marijuana use differentiated those with a substance use disorder with or without depression from those with depression without a substance use disorder in adjusted models. In conclusion, comorbid substance use disorders and depression are highly prevalent among these urban African Americans. Insight into the unique childhood and adolescent risk factors for depression compared to substance use disorders is critical to intervention development in urban communities. Results suggest that these programs must consider individual behaviors, as well as the early family dynamic. PMID:22762959

Determinants of access to health care for depression in 49 countries: A multilevel analysis.

The relative importance of individual and country-level factors influencing access to diagnosis and treatment for depression across the world is fairly unknown. We analysed cross-national data from the WHO World Health Surveys. Depression diagnosis and access to health care were ascertained using a structured interview. Logistic Bayesian Multilevel analyses were performed to establish individual and country level factors associated with: (1) receiving a diagnosis and (2) accessing treatment for depression if a diagnosis was ascertained. The sample included 7870 individuals from 49 countries who met ICD-10 criteria for depressive episode in the past 12 months. A third (32%) of these individuals had ever been diagnosed with depression in their lifetime. Among those diagnosed with depression, 66% reported to have ever received treatment for depression. Although individual factors were more important determinants of access to treatment for depression, country-level factors explained 27.6% of the variance in access to diagnosis and 24.1% in access to treatment. Access to treatment for depression improved with increasing country income. Female gender, better education, the presence of physical co-morbidity, more material assets, and living in urban areas were individual level determinants of better access. Data on other contextual factors was not available. Unmet need was likely underestimated, since only lifetime treatment data was available. This study highlights major inequalities in access to a diagnosis and treatment of depression. Unlike the prevalence of depression, where contextual factors have shown to have less importance, a significant proportion of the variance in access to depression care was explained by country-level income.

The relationship between low socioeconomic status (SES) and depressive symptoms is well described, also in older persons. Although studies have found associations between low SES and unhealthy lifestyle factors, and between unhealthy lifestyle factors and depressive symptoms, not much is known about unhealthy lifestyles as a potential explanation of socioeconomic differences in depressive symptoms in older persons. To study the independent pathways between SES (education, income, perceived income, and financial assets), lifestyle factors (smoking, alcohol use, body mass index, and physical activity), and incident depressive symptoms (Center for Epidemiologic Studies-Depression [CES-D 10] and reported use of antidepressant medication), we used 9 years of follow-up data (1997-2007) from 2,694 American black and white participants aged 70-79 years from the Health, Aging, and Body Composition (Health ABC) study. At baseline, 12.1% of the study population showed prevalent depressive symptoms, use of antidepressant medication, or treatment of depression in the 5 years prior to baseline. These persons were excluded from the analyses. Over a period of 9 years time, 860 participants (31.9%) developed depressive symptoms. Adjusted hazard ratios for incident depressive symptoms were higher in participants from lower SES groups compared with the highest SES group. The strongest relationships were found for black men. Although unhealthy lifestyle factors were consistently associated with low SES, they were weakly related to incident depressive symptoms. Lifestyle factors did not significantly reduce hazard ratios for depressive symptoms by SES. In generally healthy persons aged 70-79 years, lifestyle factors do not explain the relationship between SES and depressive symptoms. Copyright © 2013 American Association for Geriatric Psychiatry.

Background Depression and anxiety are established psychosocial risk factors for coronary heart disease. Contemporary data on their prevalence and associations with other risk factors were evaluated as part of the EUROASPIRE IV survey. Design The design of this study was cross-sectional. Methods The study group consisted of 7589 patients from 24 European countries examined at a median of 1.4 years after hospitalisation due to coronary heart disease events. Depression and anxiety were assessed using the Hospital Anxiety and Depression Scale. Results Symptoms of anxiety (Hospital Anxiety and Depression Scale-Anxiety score ≥8) were seen in 26.3% of participants and were more prevalent in women (39.4%) vs men (22.1%). Of the patients, 22.4% (30.6% of women and 19.8% of men) had symptoms of depression (Hospital Anxiety and Depression Scale-Depression score ≥8). Nevertheless, antidepressants and anti-anxiety medications were prescribed to only 2.4% of patients at hospital discharge, and 2.7% and 5.0% of patients, respectively, continued to take them at interview. Both anxiety and depression were associated with female gender, lower educational level and more sedentary lifestyle. Anxiety was more prevalent in younger age groups and depression rates increased with advancing age. Depression was positively associated with current smoking, central obesity and self-reported diabetes. A number of positive lifestyle changes reduced the odds of anxiety and depression. Conclusions A substantial proportion of patients have anxiety and depression symptoms after coronary heart disease events but these conditions are undertreated. These disorders, especially depression, are associated with other risk factors, including educational level, sedentary lifestyle, smoking, unhealthy diet and reduced compliance with risk factor modification.

Involvement of Brain-Derived Neurotrophic Factor in Late-Life Depression

PubMed Central

Dwivedi, Yogesh

2013-01-01

Brain-derived neurotrophic factor (BDNF), one of the major neurotrophic factors, plays an important role in the maintenance and survival of neurons, synaptic integrity, and synaptic plasticity. Evidence suggests that BDNF is involved in major depression, such that the level of BDNF is decreased in depressed patients and that antidepressants reverse this decrease. Stress, a major factor in depression, also modulates BDNF expression. These studies have led to the proposal of the neurotrophin hypothesis of depression. Late-life depression is associated with disturbances in structural and neural plasticity as well as impairments in cognitive behavior. Stress and aging also play a crucial role in late-life depression. Many recent studies have suggested that not only expression of BDNF is decreased in the serum/plasma of patients with late-life depression, but structural abnormalities in the brain of these patients may be associated with a polymorphism in the BDNF gene, and that there is a relationship between a BDNF polymorphism and antidepressant remission rates. This review provides a critical review of the involvement of BDNF in major depression, in general, and in late-life depression, in particular. PMID:23570887

This study examined the association between postnatal depressive symptoms and a set of demographic and psychosocial factors among 604 women attending a public hospital for postnatal care in Mexico City. Specific profiles of women that would indicate an increased probability for developing postnatal depression (PND) based on discrete combinations of risk and protective factors were generated. In a logistic model, followed by the estimation of predicted probabilities, we examined the association between depressive symptomatology and psychosocial factors: low social support, unplanned pregnancies, history of depression, and exposure to moderate or severe intimate partner violence (IPV) during pregnancy. Postnatal depressive symptomatology was reported by 10.6 % of the women, as measured by scores at 12 or above on the Edinburgh Postnatal Depression Scale. The cumulative probability of presenting PND in the simultaneous presence of the psychosocial factors was 67.0 %; however, this could be reduced to 5.5 % through preventive measures that work to eliminate low social support, unplanned pregnancy, and exposure to severe IPV during pregnancy. Early identification of psychosocial risk factors, specifically low social support, unplanned pregnancies, history of depression, and exposure to violence during pregnancy, is recommended.

Background To determine the psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in patients with breast cancer and determine the suitability of the instrument for use with this clinical group. Methods A cross-sectional design was used. The study used a pooled data set from three breast cancer clinical groups. The dependent variables were HADS anxiety and depression sub-scale scores. Exploratory and confirmatory factor analyses were conducted on the HADS to determine its psychometric properties in 110 patients with breast cancer. Seven models were tested to determine model fit to the data. Results Both factor analysis methods indicated that three-factor models provided a better fit to the data compared to two-factor (anxiety and depression) models for breast cancer patients. Clark and Watson's three factor tripartite and three factor hierarchical models provided the best fit. Conclusion The underlying factor structure of the HADS in breast cancer patients comprises three distinct, but correlated factors, negative affectivity, autonomic anxiety and anhedonic depression. The clinical utility of the HADS in screening for anxiety and depression in breast cancer patients may be enhanced by using a modified scoring procedure based on a three-factor model of psychological distress. This proposed alternate scoring method involving regressing autonomic anxiety and anhedonic depression factors onto the third factor (negative affectivity) requires further investigation in order to establish its efficacy.

To investigate the roles of physical activity (exercise) and sociodemographic factors in depressive symptoms among men and women in the United States. 2011 U.S. Behavioral Risk Factor Surveillance System (BRFSS). Patient Health Questionnaire Depression Scale (PHQ-8) scores are aggregated and divided into five categories. An ordered switching probability model with binary endogenous physical activity is developed to accommodate ordinality of depression categories and ameliorate statistical biases due to endogeneity of physical activity. Average treatment effects suggest physical activity ameliorates depressive symptoms among mildly and moderately depressed individuals, most notably among mildly depressed women. Gender differences exist in the roles of sociodemographic factors, with age, income, race, education, employment status, and recent mental health condition playing differentiated roles in affecting depressive symptoms. Regular physical activity reduces depressive symptoms among both men and women with mild to moderate depression, notably among women. © Health Research and Educational Trust.

This study measured antenatal risk factors for postnatal depression in the Australian population, both singly and in combination. Risk factor data were gathered antenatally and depressive symptoms measured via the beyondblue National Postnatal Depression Program, a large prospective cohort study into perinatal mental health, conducted in all six states of Australia, and in the Australian Capital Territory, between 2002 and 2005. Pregnant women were screened for symptoms of postnatal depression at antenatal clinics in maternity services around Australia using the Edinburgh Postnatal Depression Scale (EPDS) and a psychosocial risk factor questionnaire that covered key demographic and psychosocial information. From a total of 40,333 participants, we collected antenatal EPDS data from 35,374 women and 3144 of these had a score >12 (8.9%). Subsequently, efforts were made to follow-up 22,968 women with a postnatal EPDS. Of 12,361 women who completed postnatal EPDS forms, 925 (7.5%) had an EPDS score >12. Antenatal depression together with a prior history of depression and a low level of partner support were the strongest independent antenatal predictors of a postnatal EPDS score >12. The two main limitations of the study were the use of the EPDS (a self-report screening tool) as the measure of depressive symptoms rather than a clinical diagnosis, and the rate of attrition between antenatal screening and the collection of postnatal follow-up data. Antenatal depressive symptoms appear to be as common as postnatal depressive symptoms. Previous depression, current depression/anxiety, and low partner support are found to be key antenatal risk factors for postnatal depression in this large prospective cohort, consistent with existing meta-analytic surveys. Current depression/anxiety (and to some extent social support) may be amenable to change and can therefore be targeted for intervention.

To explore the literature regarding prevention of depression in the workplace. Literature review of what the author believes are seminal articles highlighting workplace factors and interventions in preventing depression in the workplace. Employees can help prevent depression by building protective factors such as better coping and stress management skills. Employees may be candidates for depression screening if they have certain risk factors such as performance concerns. Organizational interventions such as improving mental health literacy and focusing on work-life balance may help prevent depression in the workplace but deserve further study. A strategy to prevent depression in the workplace can include developing individual resilience, screening high-risk individuals and reducing that risk, improving organizational literacy, and integrating workplace and health care systems to allow access to proactive quality interventions.

Identifying depressive symptom trajectory groups among Korean adults and psychosocial factors as group determinants.

Kwon, Tae Yeon

2015-06-01

Longitudinal research is needed to examine the depressive symptom trajectories of different groups during adulthood and their antecedents and consequences, because depressive symptoms may be changeable and heterogeneous over time. This study examined the number of trajectory groups describing the depressive symptoms of Korean adults, as well as the shape of the trajectories and the association between trajectory group membership and psychosocial factors identified based on the ecosystem model. This study used Nagin's semi-parametric group-based modeling to analyze Year 1 to Year 7 data from Korea Welfare Panel Survey (N = 13,735), a nationally representative sample of community-dwelling adults. Three distinct trajectory groups were identified: a low stable depressive symptoms group, a moderate depressive symptoms group and a high depressive symptoms group. Result from multinominal logit analysis showed that all psychosocial factors except family relationships affected the likelihood of membership in the three depressive symptoms groups. Especially, self-esteem was the psychosocial factor with the largest impact on depressive symptom trajectory group membership. When screening for depressive symptoms, individuals with a low socioeconomic status should be a primary concern and intervention should be made available to them. Prevention or intervention with members of the identified trajectory groups would likely require integrative approaches targeting psychosocial factors across multiple contexts. © The Author(s) 2015.

Posttraumatic stress disorder (PTSD) is highly comorbid with anxiety and depressive disorders, which is suggestive of shared variance or common underlying dimensions. The purpose of the present study was to examine the relationship between the latent factors of PTSD with the constructs of anxiety and depression in order to increase understanding of the co-occurrence of these disorders. Data were collected from a nonclinical sample of 186 trauma-exposed participants using the PTSD Checklist and Hospital Anxiety and Depression Scale. Confirmatory factor analyses were conducted to determine model fit comparing 3 PTSD factor structure models, followed by Wald tests comparing the relationships between PTSD factors and the core dimensions of anxiety and depression. In model comparisons, the 5-factor dysphoric arousal model of PTSD provided the best fit for the data, compared to the emotional numbing and dysphoria models of PTSD. Compared to anxious arousal, the dysphoric arousal and numbing factors of PTSD were more related to depression severity. Numbing, anxious arousal, and dysphoric arousal were not differentially related to the latent anxiety factor. The underlying factors of PTSD contain aspects of the core dimensions of both anxiety and depression. The heterogeneity of PTSD's associations with anxiety and depressive constructs requires additional empirical exploration because clarification regarding these relationships will impact diagnostic classification as well as clinical practice.

Depression is an adverse outcome frequently seen in carers. With the increasing ageing population and reliance on informal carers, this study aims to identify factors associated with depression in carers in the older age group, using factors that have not been previously investigated. We conducted a cross-sectional analysis of 202 older carers using the Geriatric Depression scale, demographics, personality traits, attitudes to ageing and other carer characteristics. Increased hours spent caring and higher levels of neuroticism were all factors associated with depression. The care-recipient diagnosis, other personality traits, attitudes to ageing, leisure-physical activity (PA) and domestic-PA were not significantly associated with depression. These findings have important implications for interventions to target at-risk carers. Copyright © 2015 John Wiley & Sons, Ltd.

Context. Observations of the Sun tell us that its granular and subgranular small-scale magnetism has significant consequences for global quantities such as the total solar irradiance or convective blueshift of spectral lines. Aims: In this paper, properties of the small-scale magnetism of four cool stellar atmospheres, including the Sun, are investigated, and in particular its effects on the radiative intensity and flux. Methods: We carried out three-dimensional radiation magnetohydrodynamic simulations with the CO5BOLD code in two different settings: with and without a magnetic field. These are thought to represent states of high and low small-scale magnetic activity of a stellar magnetic cycle. Results: We find that the presence of small-scale magnetism increases the bolometric intensity and flux in all investigated models. The surplus in radiative flux of the magnetic over the magnetic field-free atmosphere increases with increasing effective temperature, Teff, from 0.47% for spectral type K8V to 1.05% for the solar model, but decreases for higher effective temperatures than solar. The degree of evacuation of the magnetic flux concentrations monotonically increases with Teff as does their depression of the visible optical surface, that is the Wilson depression. Nevertheless, the strength of the field concentrations on this surface stays remarkably unchanged at ≈1560 G throughout the considered range of spectral types. With respect to the surrounding gas pressure, the field strength is close to (thermal) equipartition for the Sun and spectral type F5V but is clearly sub-equipartition for K2V and more so for K8V. The magnetic flux concentrations appear most conspicuous for model K2V owing to their high brightness contrast. Conclusions: For mean magnetic flux densities of approximately 50 G, we expect the small-scale magnetism of stars in the spectral range from F5V to K8V to produce a positive contribution to their bolometric luminosity. The modulation seems to be most effective for early G-type stars.

Phosphorus (P) flux potential can predict the trend of phosphorus release from wetland sediments to water and provide scientific parameters for further monitoring and management for phosphorus flux from wetland sediments to overlying water. Many studies have focused on factors affecting sediment P flux potential in sediment-water interface, but rarely on the relationship among these factors. In the present study, experiment on sediment P flux potential in sediment-water interface was conducted in six wetlands in Hulun Buir grassland, China and the relationships among sediment P flux potential in sediment-water interface, sediment physical properties, and sediment chemical characteristics were examined. Principal component analysis and path analysis were used to discuss these data in correlation coefficient, direct, and indirect effects on sediment P flux potential in sediment-water interface. Results indicated that the major factors affecting sediment P flux potential in sediment-water interface were amount of organophosphate-degradation bacterium in sediment, Ca-P content, and total phosphorus concentrations. The factors of direct influence sediment P flux potential were sediment Ca-P content, Olsen-P content, SOC content, and sediment Al-P content. The indirect influence sediment P flux potential in sediment-water interface was sediment Olsen-P content, sediment SOC content, sediment Ca-P content, and sediment Al-P content. And the standard multiple regression describing the relationship between sediment P flux potential in sediment-water interface and its major effect factors was Y = 5.849 - 1.025X 1  - 1.995X 2  + 0.188X 3  - 0.282X 4 (r = 0.9298, p < 0.01, n = 96), where Y is sediment P flux potential in sediment-water interface, X 1 is sediment Ca-P content, X 2 is sediment Olsen-P content, X 3 is sediment SOC content, and X 4 is sediment Al-P content. Therefore, future research will focus on these sediment properties to analyze the interrelation among sediment properties factors, main vegetable factors, and environment factors which influence the sediment P flux potential in sediment-water interface.

Importance of the field Coronary heart disease (CHD) and depression are two leading causes of death and disability in the United States and worldwide. Depression is especially common in cardiac patients, and there is growing evidence that depression is a risk factor for fatal and non-fatal events in CHD patients. Areas covered in this review This paper reviews current literature of depression as a risk factor for CHD along with pharmacologic and non-pharmacologic treatments for depression in cardiac patients. What the reader will gain Readers will gain knowledge about the importance of depression as a CHD risk factor and learn the results of efforts to treat depressed CHD patients. Take home message Although randomized clinical trials (RCTs) of medication and non-pharmacologic therapies have not demonstrated that treating depression improves survival, there is evidence that treating depressed patients can reduce depressive symptoms and improve quality of life. Additional RCTs are needed, including evaluation of non-pharmacologic therapies such as exercise, to examine the effects of treatment of depression on medical and psychosocial outcomes.

2013-01-01

The development of depressive disorders had long been attributed to monoamine variations, and pharmacological treatment strategies likewise focused on methods of altering monoamine availability. However, the limited success achieved by treatments that altered these processes spurred the search for alternative mechanisms and treatments. Here we provide a brief overview concerning a possible role for pro-inflammatory cytokines and growth factors in major depression, as well as the possibility of targeting these factors in treating this disorder. The data suggest that focusing on one or another cytokine or growth factor might be counterproductive, especially as these factors may act sequentially or in parallel in affecting depressive disorders. It is also suggested that cytokines and growth factors might be useful biomarkers for individualized treatments of depressive illnesses. PMID:23675319

Factors accounting for the association between anxiety and depression, and eczema: the Hordaland health study (HUSK)

PubMed Central

2010-01-01

Background The association between anxiety and depression, and eczema is well known in the literature, but factors underlying this association remain unclear. Low levels of omega-3 fatty acids and female gender have been found to be associated with both depression and eczema. Somatization and health anxiety are known to be associated with anxiety and depression, further, somatization symptoms and health anxiety have also been found in several dermatological conditions. Accordingly, omega-3 fatty acid supplement, female gender, somatization and health anxiety are possible contributing factors in the association between anxiety and depression, and eczema. The aim of the study is to examine the relevance of proposed contributing factors for the association between anxiety and depression, and eczema, including, omega-3 fatty acid supplement, female gender, health anxiety and somatization. Methods Anxiety and depression was measured in the general population (n = 15715) employing the Hospital Anxiety and Depression Scale (HADS). Information on eczema, female gender, omega-3 fatty acid supplement, health anxiety and somatization was obtained by self-report. Results Somatization and health anxiety accounted for more than half of the association between anxiety/depression, and eczema, while the other factors examined were of minor relevance for the association of interest. Conclusions We found no support for female gender and omega-3 fatty acid supplement as contributing factors in the association between anxiety/depression, and eczema. Somatization and health anxiety accounted for about half of the association between anxiety/depression, and eczema, somatization contributed most. The association between anxiety/depression, and eczema was insignificant after adjustment for somatization and health anxiety. Biological mechanisms underlying the mediating effect of somatization are yet to be revealed. PMID:20412596

Background The relationship between low socioeconomic status (SES) and depressive symptoms is well described, also in older persons. Although studies have found associations between low SES and unhealthy lifestyle factors and between unhealthy lifestyle factors and depressive symptoms, not much is known about unhealthy lifestyles as a potential explanation of socioeconomic differences in depressive symptoms in older persons. Methods To study the independent pathways between SES (education, income, perceived income, and financial assets), lifestyle factors (smoking, alcohol use, body mass index, and physical activity), and incident depressive symptoms (CES-D 10 and reported use of antidepressant medication), we used 9 years of follow-up data (1997–2007) from 2,694 American black and white participants aged 70–79 from the Health, Aging, and Body Composition (Health ABC) study. At baseline, 12.1% of the study population showed prevalent depressive symptoms, use of antidepressant medication, or treatment of depression in the five years prior to baseline. These persons were excluded from the analyses. Results Over a period of 9 years time, 860 participants (31.9%) developed depressive symptoms. Adjusted hazard ratios for incident depressive symptoms were higher in participants from lower SES groups compared to the highest SES group. The strongest relationships were found for black men. Although unhealthy lifestyle factors were consistently associated with low SES, they were weakly related to incident depressive symptoms. Lifestyle factors did not significantly reduce hazard ratios for depressive symptoms by SES. Conclusion In generally healthy persons aged 70–79 years lifestyle factors do not explain the relationship between SES and depressive symptoms. (250) PMID:23567402

Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian hospitals. A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. The highest prevalence was anxiety (28.6%) followed by depression (10.7%) and stress (7.9%). Depression, anxiety and stress between seven hospitals were not significantly different ( P >0.05). Male medical officers significantly experienced more anxiety symptoms than female medical officers ( P =0.0022), however depression and stress symptoms between male and female medical officers were not significantly different ( P >0.05). Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals ( P >0.05). The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers' anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

Subthreshold depressive disorder is one of the best established risk factors for the onset of full-syndrome depressive disorders. However, many youths with subthreshold depressive disorder do not develop full-syndrome depression. We examined predictors of escalation to full-syndrome depressive disorders in a community sample of 225 adolescents with subthreshold depressive disorder. Criteria for subthreshold depressive disorder were an episode of depressed mood or loss of interest or pleasure lasting at least 1 week and at least two of the seven other DSM-IV-associated symptoms for major depression. Participants were assessed four times from mid-adolescence to age 30 years using semistructured diagnostic interviews. The estimated risk for escalation to full-syndrome depressive disorders was 67%. Five variables accounted for unique variance in predicting escalation: severity of depressive symptoms, medical conditions/symptoms, history of suicidal ideation, history of anxiety disorder, and familial loading for depression. Adolescents with three or more risk factors had an estimated 90% chance of escalating to full-syndrome depressive disorder, compared with 47% of adolescents with fewer than three risk factors. These data may be useful in identifying a subgroup of youths with subthreshold depressive disorder who are at especially high risk for escalating to full-syndrome depressive disorders.

Research into the association between psychosocial factors and depression in End-Stage Renal Disease (ESRD) has expanded considerably in recent years identifying a range of factors that may act as important risk and protective factors of depression for this population. The present study provides the first systematic review and meta-analysis of this body of research. Published studies reporting associations between any psychosocial factor and depression were identified and retrieved from Medline, Embase, and PsycINFO, by applying optimised search strategies. Mean effect sizes were calculated for the associations across five psychosocial constructs (social support, personality attributes, cognitive appraisal, coping process, stress/stressor). Multiple hierarchical meta-regression analysis was applied to examine the moderating effects of methodological and substantive factors on the strength of the observed associations. 57 studies covering 58 independent samples with 5956 participants were identified, resulting in 246 effect sizes of the association between a range of psychosocial factors and depression. The overall mean effect size (Pearsons correlation coefficient) of the association between psychosocial factor and depression was 0.36. The effect sizes between the five psychosocial constructs and depression ranged from medium (0.27) to large levels (0.46) with personality attributes (0.46) and cognitive appraisal (0.46) having the largest effect sizes. In the meta-regression analyses, identified demographic (gender, age, location of study) and treatment (type of dialysis) characteristics moderated the strength of the associations with depression. The current analysis documents a moderate to large association between the presence of psychosocial risk factors and depression in ESRD. 2011. Published by Elsevier Inc. All rights reserved.

[Family environment risk factors of depression in adolescence].

PubMed

Greszta, Elzbieta

2006-01-01

General psychosocial theories of developmental psychopathology assert that family environment plays a significant role in forming both adaptive and maladaptive functioning of children. Also virtually all theories of depression assert that faulty parent-child relationships play a major role in the aetiology of this disorder. According these theoretical formulations familial risk factors have been the focus of most research on depression in adolescence. Several studies have shown that insecure attachment and parenting characterized by coldness, rejection, harsh discipline and unsupportive behaviour is positively related to adolescent depressive symptoms. Some research indicates that authoritative parenting, conceptualized as a composite of warmth, accept-involvement, firm control, and democratic discipline, is associated with the least depressive symptoms among adolescents. Pathogenetic factors within the family environment, such as parental depression, changes of family structure, violence or neglect, can also contribute to depression in adolescence. A causal relationship between anomalous parenting and depression is probably the interplay among genetic, cognitive, emotional, interpersonal and family environmental factors.

To investigate the relationships between workplace psychosocial factors, work/family conflicts, depression, and health-related presenteeism in a sample of employees who were randomly selected from the communities. A cross-sectional study of 4032 employees representative of the working population aged 25 to 64 years in Alberta, Canada. Data about workplace characteristics, depression, and health-related presenteeism were collected through telephone. In the participants, 47.3% and 42.9% reported some degree of impaired job performance in completing work and avoiding distraction, respectively. Major depression is the strongest factor associated with avoiding distraction. Job strain and effort-reward imbalance seemed to affect job performance through severity of depression but not major depression. Negative work environment may directly and indirectly affect job performance. Workplace health promotion activities should target organizational factors such as job strain and effort-reward imbalance and work/family conflicts so as to reduce the risk of depression and the direct and indirect effects of these risk factors and depression on productivity.

Objectives. We examined depression within a multidimensional framework consisting of genetic, environmental, and sociobehavioral factors and, using machine learning algorithms, explored interactions among these factors that might better explain the etiology of depressive symptoms. Methods. We measured current depressive symptoms using the Center for Epidemiologic Studies Depression Scale (n = 6378 participants in the Wisconsin Longitudinal Study). Genetic factors were 78 single nucleotide polymorphisms (SNPs); environmental factors—13 stressful life events (SLEs), plus a composite proportion of SLEs index; and sociobehavioral factors—18 personality, intelligence, and other health or behavioral measures. We performed traditional SNP associations via logistic regression likelihood ratio testing and explored interactions with support vector machines and Bayesian networks. Results. After correction for multiple testing, we found no significant single genotypic associations with depressive symptoms. Machine learning algorithms showed no evidence of interactions. Naïve Bayes produced the best models in both subsets and included only environmental and sociobehavioral factors. Conclusions. We found no single or interactive associations with genetic factors and depressive symptoms. Various environmental and sociobehavioral factors were more predictive of depressive symptoms, yet their impacts were independent of one another. A genome-wide analysis of genetic alterations using machine learning methodologies will provide a framework for identifying genetic–environmental–sociobehavioral interactions in depressive symptoms.

Cardiovascular Disease, Psychosocial Factors, and Genetics: The Case of Depression

PubMed Central

Mulle, Jennifer Gladys; Vaccarino, Viola

2013-01-01

Psychosocial factors are associated with cardiovascular disease, but little is known about the role of genetics in this relationship. Focusing on the well-studied phenotype of depression, current data show that there are shared genetic factors that may give rise to both depression and CVD, and these genetic risks appear to be modified by gender. This pleiotropic effect suggests that a single pathway, when perturbed, gives rise to the dual phenotypes of CVD and depression. The data also suggest that women contribute disproportionately to the depression-CVD comorbidity, and this unbalanced contribution is attributable, in part, to genetic factors. While the underlying biology behind this relationship is unclear, recent data support contributions from inflammatory or serotonergic pathways toward the comorbidity between CVD and depression. Even without knowledge of a specific mechanism, epidemiological observations offer new directions to explain the relationship between depression and CVD that have both research and clinical applications.

Although stress reaction is high among nursing staff and nursing students in the Middle East and its effect on life is known, there are scant studies reporting on these clinical and social features. In addition, there are no studies reporting on factors that influence career choice among this group. This study aimed to investigate factors that influence career choice among nursing students and their possible association with depressive symptoms. Participants were 150 (84.7% response rate) nursing students randomly selected from each academic year at the Nursing College/Jordan University of Science and Technology. Participants consented and completed the socio-demographic data collection sheet. The Arabic version of the Beck Depression Inventory-II Scale was used to assess participants with respect to depressive symptoms. A modified list of factors influencing career choice and a Likert scale to assess the level of sadness and the degree of religiosity were used as well. Students ranked the most important three factors influencing their career selection as family decision, religious factors, and the desire to care for others. The prevalence of depression among the sample was 26%. Students who had a desire to care for others were less likely to suffer from depression and those who chose nursing as their career due to religious factors were significantly less depressed than those who did not. Meanwhile, students who chose nursing under family pressure or because of a lack of alternative opportunities were more depressed. The odds ratio for depressive symptoms was 0.24 when students chose nursing because of religious factors, whereas it was 4.92 when the family strongly influenced the student's career decision and 3.61 when a nursing career was the only perceived opportunity available. The main factors associated with depression among this sample of nursing students were pressure from their family to choose a nursing career and having no other career or employment opportunities. Religiosity was negatively associated with depression and may act as a protective factor; however, future studies using longitudinal designs will need to confirm this hypothesis.

Most previous studies of the depression-mortality association have not examined distinct depressive symptom clusters. This ex post facto study examined which aspects of depression may account for its association with mortality. The Center for Epidemiologic Studies Depression Scale (CES-D) was administered to 3,867 community dwelling adults. Cox proportional hazards procedures estimated the risk of mortality as a function of depression status and each of 4 CES-D factor scores. Depressed participants (CES-D ≥ 16) had a 1.23-fold higher risk of mortality (95% CI 1.03-1.49), adjusting for sociodemographics. Somatic Complaints (SC) was the only factor to predict mortality (HR 1.19, 95% CI 1.03-1.38). After excluding SC, CES-D scores no longer predicted mortality (HR .98, 95% CI .79-1.21). The association between CES-D depressive symptoms and mortality appears to be a function of the SC factor. The association between non-somatic depressive symptoms and mortality may not be as robust as past findings suggest. PMID:19936326

To compare depression identification and management perceptions and practices between professions and disciplines in primary care and examine factors that increase the likelihood of administering a standardized depression screening instrument, asking about patients' depressive symptoms, and using best practice when managing depressed adolescents. Data came from an online survey of clinicians in Minnesota (20% response rate). Analyses involved bivariate tests and linear regressions. The analytic sample comprised 260 family medicine physicians, 127 pediatricians, 96 family nurse practitioners, and 54 pediatric nurse practitioners. Overall, few differences emerged between physicians and nurse practitioners or family and pediatric clinicians regarding addressing depression among adolescents. Two factors associated with administering a standardized instrument included having clear protocols for follow-up after depression screening and feeling better prepared to address depression among adolescents. Enhancing clinicians' competence to address depression and developing postscreening protocols could help providers implement universal screening in primary care.

Our aim was to evaluate whether personality factors significantly contribute to the identification of depression in older primary care patients, even after controlling for depressive symptoms. We examined the association between personality factors and the identification of depression among 318 older adults who participated in the Spectrum study. High neuroticism (unadjusted Odds Ratio (OR) 2.36, 95% Confidence Interval (CI) [1.42, 3.93]) and low extraversion (adjusted OR 2.24, CI [1.26, 4.00]) were associated with physician identification of depression. Persons with high conscientiousness were less likely to be identified as depressed by the doctor (adjusted OR 0.45, CI [0.22, 0.91]). Personality factors influence the identification of depression among older persons in primary care over and above the relationship of depressive symptoms with physician identification. Knowledge of personality may influence the diagnosis and treatment of depression in primary care. Copyright 2007 John Wiley & Sons, Ltd.

Sex differences in depression and anxiety disorders: potential biological determinants.

PubMed

Altemus, Margaret

2006-11-01

The phenomenon of higher rates of affective disorders in women illustrates many of the difficulties as well as promises of translating preclinical models to human disorders. Abnormalities in the regulation of the hypothalamic-pituitary adrenal axis and the sympathoadrenomedullary system have been identified in depression and anxiety disorders, and these disorders are clearly precipitated and exacerbated by stress. Despite the striking sex difference in the prevalence of depression and anxiety disorders, attempts to identify corresponding sex differences in stress response reactivity in animal models have met with limited success. Processes which may contribute to increased rates of affective disorders in women are greater fluxes in reproductive hormones across the life span, and increased sensitivity to catecholamine augmentation of emotional memory consolidation.

This study was conducted to compare the degree of depression between men and women and to identify factors influencing their depression. Participants in this cross-sectional descriptive study were 263 persons over 65 years old (men: 103, women: 160). Data were collected through face to face interviews using questionnaires and were done in two urban areas in 2010. Research instruments utilized in this study were SGDS, MMSE-K, SRH, FILE, sleep pattern scale, family and friend support scale, and social support scale. Multivariate regression analysis was performed to identify factors influencing depression in elders. The proportions of participants with depression were significantly different between men and women (52.4% vs. 67.5%). Regression model for depression in elderly men significantly accounted for 54%; disease stress (32%), economic stress (10%), perceived health status (4%), and family support, educational level, age, and hypertension. Regression model for depression in elderly women significantly accounted for 47%; disease stress (25%), perceived social loneliness (8%), friend support (5%), family stress (4%), and sleep satisfaction, and family support. Results demonstrate that depression is an important health problem for elders, and show gender differences for factors influencing depression. These results could be used in the developing depression prevention programs.

Depression is more than the sum-score of its parts: individual DSM symptoms have different risk factors

Background For diagnostic purposes, the nine symptoms that compose the DSM-5 criteria for Major Depressive Disorder (MDD) are assumed to be interchangeable indicators of one underlying disorder, implying that they should all have similar risk factors. The present study investigates this hypothesis, utilizing a population cohort that shifts from low to elevated depression levels. Methods We assessed the nine DSM-5 MDD criterion symptoms and seven depression risk factors (personal and family MDD history, sex, childhood stress, neuroticism, work hours, and stressful life events) in a longitudinal study of medical interns prior to and throughout internship (n=1289). We tested if risk factors varied across symptoms, and whether a latent disease model could account for heterogeneity between symptoms. Results All MDD symptoms increased significantly during residency training. Four risk factors predicted increases in unique subsets of PHQ-9 symptoms over time (depression history, childhood stress, sex, and stressful life events), while neuroticism and work hours predicted increases in all symptoms, albeit to varying magnitudes. MDD family history did not predict increases in any symptom. The strong heterogeneity of associations persisted after controlling for a latent depression factor. Conclusions The influence of risk factors varies substantially across DSM depression criterion symptoms. Since symptoms are etiologically heterogeneous, considering individual symptoms in addition to depression diagnosis might offer important insights obfuscated by symptom sum-scores. PMID:24289852

Depression is a common comorbid disorder of dementia. This study explores the prevalence of and factors associated with depressive symptomatology, and antidepressant prescription rates in severe dementia across eight European countries. In total, 414 people with severe dementia completed measures of cognition and quality of life (QoL), whilst carers completed proxy measures of activities of daily living (ADLs), depression, neuropsychiatric symptoms, QoL and comorbidity. Findings indicated that 30% of the sample had depression, whilst the highest and lowest prevalence of depression was reported in Germany and Finland, respectively. Lower QoL, the presence of pain and more frequent neuropsychiatric symptoms were associated with depressive symptomatology, whilst no significant relationship between impairment of ADLs, comorbidity, and depression emerged. Spain and Estonia had the highest and lowest rates of antidepressant prescribing, respectively, whilst Germany had the highest discrepancy between depressive symptomatology and prescription. The study highlights variations across countries in the prevalence of depressive symptomatology in severe dementia and prescription of antidepressants. Information about factors associated with depressive symptomatology may help to better identify and manage depression.

Valproic acid (VPA) intoxication incidence is increasing, because of the use of VPA in psychiatric disorders. The most common finding of VPA intoxication is central nervous system depression which leads to coma and respiratory depression. Pancreatitis, hyperammonemia, metabolic, and bone marrow failure (thrombocytopenia and leukopenia) have also been described. Treatment is mainly supportive. We present the case of an 18-year-old female patient, who made an attempt to autolysis with VPA. Our patient's VPA plasma level was very high (924 μg/mL), confirming that it was a severe intoxication. Our treatment including levocarnitine (50 mg/kg per day for 3 days), and high-flux hemodialysis was performed for four hours. The patient's hemodynamic status and mental function improved in conjunction with the acute reduction in VPA concentrations. Her subsequent hospital course was complicated by transient thrombocytopenia and levocarnitine induced hypophosphatemia. By day 6, the patient's laboratory values had completely normalized, and she was transferred to an inpatient psychiatric facility for continuing therapy. PMID:23762657

Objectives: To examine whether protective factors in the Protection for Adolescent Depression Study (PADS) moderate the impact of stressful events on depression and suicidal behaviour in the community and a clinical setting; and to study the influence of sex. Method: Participants were 283 adolescents from the community and 119 from a mood disorder clinic in Montreal. The participants were evaluated on 6 instruments measuring individual risk and protective factors. Descriptive analyses and univariate and multiple logistic regression models were carried out. Results: Risk factors predicted higher levels of depression and presence of suicidal behaviour, and protective factors predicted lower levels of depression and absence of suicidal behaviour, as expected under the vulnerability-resilience stress model. Several sex differences were observed in terms of the predictive power of risk factors (for example, hopelessness among girls and keep to themselves among boys) and protective factors (for example, focusing on the positive among girls and self-discovery among boys). Conclusions: Findings from the PADS suggest that protective factors moderate the impact of stress on depression and suicidal behaviour. Developing protection appears important in the presence of chronic conditions, such as depressive disorders, to reduce the likelihood of further episodes. The influence of sex makes it all the more relevant to target different factors for boys and girls to increase protection and decrease risk in prevention and intervention programs. PMID:25886672

Background Recently, we reported that low reward dependence, and to a lesser extent, low cooperativeness in the Temperature and Character Inventory (TCI) may be risk factors for treatment-resistant depression. Here, we analyzed additional psychological traits in these patients. Methods We administered Costa and McCrae's five-factor model personality inventory, NEO Personality Inventory-Revised (NEO-PI-R), to antidepressant-treatment resistant depressed patients (n = 35), remitted depressed patients (n = 27), and healthy controls (n = 66). We also evaluated the relationships between scores on NEO and TCI, using the same cohort of patients with treatment-resistant depression, as our previous study. Results Patients with treatment-resistant depression showed high scores for neuroticism, low scores for extraversion, openness and conscientiousness, without changes in agreeableness, on the NEO. However, patients in remitted depression showed no significant scores on NEO. Patients with treatment-resistant depression and low openness on NEO showed positive relationships with reward dependence and cooperativeness on the TCI. Conclusions Many studies have reported that depressed patients show high neuroticism, low extraversion and low conscientiousness on the NEO. Our study highlights low openness on the NEO, as a risk mediator in treatment-resistant depression. This newly identified trait should be included as a risk factor in treatment-resistant depression.

The psychometric properties of the Depression Anxiety Stress Scales (DASS) were evaluated in a normal sample of N = 717 who were also administered the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The DASS was shown to possess satisfactory psychometric properties, and the factor structure was substantiated both by exploratory and confirmatory factor analysis. In comparison to the BDI and BAI, the DASS scales showed greater separation in factor loadings. The DASS Anxiety scale correlated 0.81 with the BAI, and the DASS Depression scale correlated 0.74 with the BDI. Factor analyses suggested that the BDI differs from the DASS Depression scale primarily in that the BDI includes items such as weight loss, insomnia, somatic preoccupation and irritability, which fail to discriminate between depression and other affective states. The factor structure of the combined BDI and BAI items was virtually identical to that reported by Beck for a sample of diagnosed depressed and anxious patients, supporting the view that these clinical states are more severe expressions of the same states that may be discerned in normals. Implications of the results for the conceptualisation of depression, anxiety and tension/stress are considered, and the utility of the DASS scales in discriminating between these constructs is discussed.

Background Trait negative affect and trait positive affect are affective vulnerabilities to depressive symptoms in adolescence and adulthood. While trait affect and the state affect characteristic of depressive symptoms are proposed to be theoretically distinct, no studies have established that these constructs are statistically distinct. Therefore, the purpose of the current study was to determine whether the trait affect (e.g. temperament dimensions) that predicts depressive symptoms and the state affect characteristic of depressive symptoms are statistically distinct among early adolescents and adults. We hypothesized that trait negative affect, trait positive affect, and depressive symptoms would represent largely distinct factors in both samples. Method Participants were 268 early adolescents (53.73% female) and 321 young adults (70.09% female) who completed self-report measures of demographic information, trait affect, and depressive symptoms. Results Principal axis factoring with oblique rotation for both samples indicated distinct adolescent factor loadings and overlapping adult factor loadings. Confirmatory factor analyses in both samples supported distinct but related relationships between trait NA, trait PA, and depressive symptoms. Limitations Study limitations include our cross-sectional design that prevented examination of self-reported fluctuations in trait affect and depressive symptoms and the unknown potential effects of self-report biases among adolescents and adults. Conclusions Findings support existing theoretical distinctions between adolescent constructs but highlight a need to revise or remove items to distinguish measurements of adult trait affect and depressive symptoms. Adolescent trait affect and depressive symptoms are statistically distinct, but adult trait affect and depressive symptoms statistically overlap and warrant further consideration. PMID:27085163

Increasing evidence suggests that postnatal paternal depression is associated with adverse emotional, behavioural and cognitive outcomes in children. Despite this, few studies have determined the prevalence of fathers' depressive symptoms during the first few years of their children's lives and explored what factors are related to these symptoms. We estimated the prevalence and examined associated risk factors of paternal depressive symptoms in a nationally representative sample of fathers with children aged between 9 months and 7 years old from the Millennium cohort study. The risk factors examined were maternal depressive symptoms, marital conflict, child temperament, child gender, paternal education, fathers' ethnic background, fathers' employment status, family housing, family income and paternal age. Secondary data analysis was conducted using the UK Millennium cohort study, which consisted of data from England, Scotland, Wales and Northern Ireland of families with infants born in the year 2000/2001. Data from four sweeps were used from when children in the cohort were aged 9 months, 3, 5 and 7 years old (n = 5155-12,396). The prevalence of paternal depressive symptoms over time was 3.6 % at 9 months, 1.2 % at 3 years old, 1.8 % at 5 years and 2.0 % at 7 years (using Kessler cut-off points to categorise high depressive symptoms vs low depressive symptoms). Linear regression trends (using continuous measures of depressive symptoms) indicated that both paternal and maternal depressive symptoms decreased over time, suggesting similar patterns of parents' depressive symptoms after the birth of a child, but the decrease was more evident for mothers. Paternal depressive symptoms were consistently associated with fathers' unemployment, maternal depressive symptoms and marital conflict. Socioeconomic factors such as rented housing when child was 9 months and low family income when child was 5 and 7 years were also associated with higher paternal depressive symptoms. Paternal depressive symptoms decreased among fathers when their children were aged between 9 months to 3 years old. Paternal unemployment, high maternal depressive symptoms and high marital conflict were important risk factors for paternal depressive symptoms. In light of our findings, we would recommend a more family centred approach to interventions for depression in the postnatal period.

The aim of the present study was to gain insight into the prevalence of depression and its association with self-esteem, family, peer and school factors in a large-scale representative Taiwanese adolescent population. A total of 12,210 adolescent students were recruited into the present study. Subjects with a score >28 on the Center for Epidemiological Studies' Depression Scale were defined as having significant depression; the Rosenberg Self-Esteem Scale, Adolescent Family and Social Life Questionnaire and Family C-APGAR Index were applied to assess subjects' self-esteem, family, peer and school factors. The association between depression and correlates were examined on t-test and chi(2) test. The significant factors were further included in logistic regression analysis. Among 9586 participants (response rate: 86.3%), the prevalence of depression was 12.3%. The risk factors associated with depression in univariate analysis included female gender, older age, residency in urban areas, lower self-esteem, disruptive parental marriage, low family income, family conflict, poorer family function, less satisfaction with peer relationships, less connectedness to school, and poor academic performance. After adjusting the effects of sex, age and location, only subjects with lower self-esteem, higher family conflict, poorer family function, lower rank and decreased satisfaction in their peer group, and less connectedness to school were prone to depression on logistic regression. The prevalence of depression is high in Taiwanese adolescents, and the multiple factors of family, peer, school and individuals are associated with adolescent depression. The factors identified in the present study may be helpful when designing and implementing preventive intervention programs.

To determine the prevalence of depression in Mexican adult diabetics and to identify factors associated to the depression. Prolective survey. Four Mexico City hospitals (Clinica San Pedro de los Pinos IMSS, Centro Medico Nacional Siglo XXI IMSS, Hospital Gea González SSa and Centro de Salud Margarita Chorne SSa). 79 patients with diabetes mellitus type 2. The Beck Depression Inventory was used as a measure of depression. We used sociodemographic variables (age, gender, marital status, religion, education, occupation, socioeconomic status) and disease variables (years of diagnosis, other chronic medical conditions and compliance with therapeutic regimens) as the independent variables of depression. Mean age was 59 +/- 11 years (SD) and 58 (73%) were females. The frequency of depression was 46%. Factors associated to depression were: females (OR = 3.67, CI = 1.07-13.3, p = 0.03) and years of diagnosis above 15 (OR = 3.08, CI = 0.91-10.8, p = 0.07). Frequency of depression was high (46%). Gender and years of diabetes diagnosis were factors associated to depression.

Postpartum depression is related to many adverse effects in both mothers and their children; therefore, proper screening and early interventions are needed. This study aims to identify the risk factors of postpartum depression. Our primary focus is on obstetric risk factors. This study is a cross-sectional study which we extracted the data of women who gave birth between January 1st, 2010 and December 31st, 2012 from the Health Insurance Review and Assessment service (HIRA) database. We analyzed the data using multivariable logistic regression models. A total of 17,483 (1.4%) women suffered from depression during the postpartum period. Younger (<20years) and advanced maternal age (≥35years), primiparity, previous depression, peripartum hysterectomy, uterine artery embolization, preterm delivery, placental abruption, cesarean delivery, induced labor, and preeclampsia were found to increase the likelihood of having depression after delivery. Our findings suggest that there are several risk factors that lead women to postpartum depression. Therefore, early detection and well-management of the symptoms and risk factors for postpartum depression along with social support can help both physical and psychological conditions of women after childbirth.

Depression is experienced by a large proportion of the workforce and associated with high costs to employers and employees. There is little research on how the social costs of depression vary by social and cultural context. This study investigates individual, workplace and societal factors associated with greater perceived discomfort regarding depression in the workplace, greater likelihood of employees taking time off of work as a result of depression and greater likelihood of disclosure of depression to one's employer. Employees and managers (n = 7,065) were recruited from seven European countries to participate in the IDEA survey. Multivariable logistic regression models were used to examine associations between individual characteristics and country contextual characteristics in relation to workplace perceptions, likelihood of taking time off work and disclosing depression to an employer. Our findings suggest that structural factors such as benefit systems and flexible working hours are important for understanding workplace perceptions and consequences for employees with depression. However, manager responses that focus on offering help to the employee with depression appear to have stronger associations with positive perceptions in the workplace, and also with openness and disclosure by employees with depression. This study highlights the importance of individual, workplace and societal factors that may be associated with how people with depression are perceived and treated in the workplace, and, hence, factors that may be associated with openness and disclosure among employees with depression. Some responses, such as flexible working hours, may be helpful but are not necessarily sufficient, and our findings also emphasise the importance of support and openness of managers in addition to flexible working hours.

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) are highly comorbid and exhibit strong correlations with each other at both the symptom level and latent factor level. Various theories have attempted to explain this relationship. Results have been inconsistent regarding whether PTSD's negative alterations in cognition and mood factor (NACM) is significantly more related to depression, in contrast to other factors of PTSD. Confirmatory factor analysis was used to attempt to address the relationships between PTSD and MDD in a large sample of trauma-exposed combat veterans from the Ohio National Guard as part of a larger longitudinal study. Confirmatory factor analysis was used to test a bifactor model of PTSD symptoms, testing relations between PTSD's factors and a latent depressive factor. After partitioning out the common variance into the bifactor, we found that in contrast to other PTSD factors, PTSD's NACM factor was not significantly more related to depression. Instead, only the general bifactor predicted depressive symptoms. The limitations of the present study include the following: the specific measures of PTSD and MDD used were based on self-report, and the sample consisted of non-clinical, non-treatment seeking veterans. The present study suggests that the high rate of comorbidity between posttraumatic stress disorder (PTSD) and major depressive disorder is more related to underlying general distress or negative affectivity than the symptom categories of the PTSD diagnostic criteria.

The Edinburgh Postnatal Depression Scale: Screening Tool for Postpartum Anxiety as Well? Findings from a Confirmatory Factor Analysis of the Hebrew Version.

2016-04-01

The Edinburgh Postnatal Depression Scale (EPDS) was originally created as a uni-dimensional scale to screen for postpartum depression (PPD); however, evidence from various studies suggests that it is a multi-dimensional scale measuring mainly anxiety in addition to depression. The factor structure of the EPDS seems to differ across various language translations, raising questions regarding its stability. This study examined the factor structure of the Hebrew version of the EPDS to assess whether it is uni- or multi-dimensional. Seven hundred and fifteen (n = 715) women were screened at 6 weeks postpartum using the Hebrew version of the EPDS. Confirmatory factor analysis (CFA) was used to test four models derived from the literature. Of the four CFA models tested, a 9-item two factor model fit the data best, with one factor representing an underlying depression construct and the other representing an underlying anxiety construct. for Practice The Hebrew version of the EPDS appears to consist of depression and anxiety sub-scales. Given the widespread PPD screening initiatives, anxiety symptoms should be addressed in addition to depressive symptoms, and a short scale, such as the EPDS, assessing both may be efficient.

The authors sought to examine the association of vascular nutritional factors and depression in an elderly cohort of depression (currently and recently depressed) and comparison (never depressed) subjects. Nutrient intake over the past year was assessed in 196 elderly depression and comparison individuals with a Block 1998 food-frequency questionnaire. Nutrient intake, body mass index, and Keys score (a measure of the serum cholesterol-raising capacity of the diet) were determined. Subjects were age 60 and over and were participants in a longitudinal study of major depression. All subjects received psychiatric and medical comorbidity assessments; depression subjects also received psychiatric treatment. Vascular nutritional factors differed between depression and comparison subjects. The depression group had higher intake of saturated fat and cholesterol, higher body mass indices, lower alcohol intake, and higher Keys score than the comparison group. After controlling for age, sex, education, race, and medical comorbidity, associations remained for cholesterol, alcohol, and Keys score. Depression was found to be associated with overall dietary pattern as defined by total kilocalories, saturated fat, cholesterol, body mass index, polyunsaturated fat, sodium, and alcohol. This study provides evidence that dietary vascular risk factors differ in individuals with current or prior depression when compared with individuals with no history of depression.

Traditional perspectives conceptualize resilience as a trait and depression as resulting from resilience deficiency. However, research indicates that resilience varies substantially even among adults who are clinically depressed, as well as across the lifespan of an individual. Few studies have investigated resilience in depression, and even fewer have examined resilience in depressed older adults. Three hundred thirty-seven adults ≥60 years with major depressive disorder completed the Connor-Davidson Resilience Scale (CD-RISC) and measures of mental health, quality of life (QOL), and medical comorbidity. Exploratory factor analysis was used to explore the factor structure of the CD-RISC. Correlations and general linear models were used to examine associations between resilience and other variables. The rotated component matrix indicated a four-factor model. Sorting of items by highest factor loading revealed constructs associated with (1) grit, (2) active coping self-efficacy, (3) accommodative coping self-efficacy, and (4) spirituality. Resilience was significantly correlated with increased age, lower cognitive functioning, greater cerebrovascular risk, and greater medical comorbidity. Resilience was negatively associated with mental health symptoms (depression, apathy, and anxiety) and positively associated with QOL. The final optimal model identified less depression, less apathy, greater medical comorbidity, higher QOL, and minority (non-White) race as factors that significantly explained variability in resilience. Resilience was significantly associated with a range of mental health constructs in a sample of older adults with depression. Future clinical trials and dismantling studies may help determine whether interventions targeting grit, active coping, accommodative coping, and spirituality can increase resilience and help prevent and treat depression in older adults.

BACKGROUND: Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian hospitals. METHODS: A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. RESULTS: The highest prevalence was anxiety (28.6%) followed by depression (10.7%) and stress (7.9%). Depression, anxiety and stress between seven hospitals were not significantly different (P>0.05). Male medical officers significantly experienced more anxiety symptoms than female medical officers (P=0.0022), however depression and stress symptoms between male and female medical officers were not significantly different (P>0.05). Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals (P>0.05). CONCLUSION: The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers’ anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

The ten-item Edinburgh Postnatal Depression Scale (EPDS) is one of the most widely used self-report measures of postpartum depression. Although originally described as a one-dimensional measure, the recognition that depressive symptoms may be differentially experienced across cultural and racial/ethnic groups has led to studies examining structural equivalence of the EPDS in different populations. Variation of the factor structure remains understudied across racial/ethnic groups of US women. We examined the factor structure of the EPDS assessed 6 months postpartum in 515 women (29% black, 53% Hispanic, 18% white) enrolled in an urban Boston longitudinal birth cohort. Exploratory factor analysis (EFA) identified that a three-factor model, including depression, anxiety, and anhedonia subscales, was the most optimal fit in our sample as a whole and across race/ethnicity. Confirmatory factor analysis (CFA) was used to examine the fit of both the two- and three-factor models reported in prior research. CFA confirmed the best fit for a three-factor model, with minimal differences across race/ethnicity. "Things get on top of me" loaded on the anxiety factor among Hispanics, but loaded on the depression factor in whites and African Americans. These findings suggest that EPDS factor structure may need to be adjusted for diverse samples and warrants further study.

Which neighbourhood factors most consistently impact on depression and anxiety remains unclear. This study examines whether objectively obtained socioeconomic, physical and social aspects of the neighbourhood in which persons live are associated with the presence and severity of depressive and anxiety disorders. Cross-sectional data are from the Netherlands Study of Depression and Anxiety including participants (n = 2980) with and without depressive and anxiety disorders in the past year (based on DSM-based psychiatric interviews). We also determined symptom severity of depression (Inventory of Depression Symptomatology), anxiety (Beck Anxiety Inventory) and fear (Fear Questionnaire). Neighbourhood characteristics comprised socioeconomic factors (socioeconomic status, home value, number of social security beneficiaries and percentage of immigrants), physical factors (air pollution, traffic noise and availability of green space and water) and social factors (social cohesion and safety). Multilevel regression analyses were performed with the municipality as the second level while adjusting for individual sociodemographic variables and household income. Not urbanization grade, but rather neighbourhood socioecononomic factors (low socioeconomic status, more social security beneficiaries and more immigrants), physical factors (high levels of traffic noise) and social factors (lower social cohesion and less safety) were associated with the presence of depressive and anxiety disorders. Most of these neighbourhood characteristics were also associated with increased depressive and anxiety symptoms severity. These findings suggest that it is not population density in the neighbourhood, but rather the quality of socioeconomic, physical and social neighbourhood characteristics that is associated with the presence and severity of affective disorders.

2018-08-01

Temperamental effortful control and attentional networks are increasingly viewed as important underlying processes in depression and anxiety. However, it is still unknown whether these factors facilitate depressive and anxiety symptoms in the general population and, more specifically, in remitted depressed individuals. We investigated to what extent effortful control and attentional networks (i.e., Attention Network Task) explain concurrent depressive and anxious symptoms in healthy individuals (n = 270) and remitted depressed individuals (n = 90). Both samples were highly representative of the US population. Increased effortful control predicted a substantial decrease in symptoms of both depression and anxiety in the whole sample, whereas decreased efficiency of executive attention predicted a modest increase in depressive symptoms. Remitted depressed individuals did not show less effortful control nor less efficient attentional networks than healthy individuals. Moreover, clinical status did not moderate the relationship between temperamental factors and either depressive or anxiety symptoms. Limitations include the cross-sectional nature of the study. Our study shows that temperamental effortful control represents an important transdiagnostic process for depressive and anxiety symptoms in adults. Copyright © 2018 Elsevier B.V.

The three-factor structure of posttraumatic stress disorder (PTSD) specified by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, is not supported in the empirical literature. Two alternative four-factor models have received a wealth of empirical support. However, a consensus regarding which is superior has not been reached. A recent five-factor model has been shown to provide superior fit over the existing four-factor models. The present study investigated the fit of the five-factor model against the existing four-factor models and assessed the resultant factors' association with depression in a bereaved European trauma sample (N = 325). The participants were assessed for PTSD via the Harvard Trauma Questionnaire and depression via the Beck Depression Inventory. The five-factor model provided superior fit to the data compared with the existing four-factor models. In the dysphoric arousal model, depression was equally related to both dysphoric arousal and emotional numbing, whereas depression was more related to dysphoric arousal than to anxious arousal.

The current study used confirmatory factor analysis (CFA) to compare the fit of 2 factor structures for the Children's Depression Inventory (CDI) in an urban community sample of low-income youth. Results suggest that the 6-factor model developed by Craighead and colleagues (1998) was a strong fit to the pattern of symptoms reported by low-income urban youth and was a superior fit with these data than the original 5-factor model of the CDI (Kovacs, 1992). Additionally, results indicated that all 6 factors from the Craighead model contributed to the measurement of depression, including School Problems and Externalizing Problems especially for older adolescents. This pattern of findings may reflect distinct contextual influences of urban poverty on the manifestation and measurement of depression in youth. (c) 2014 APA, all rights reserved.

Recently socioeconomic status (SES) and job stress index received more attention to affect mental health. Folate intake has been implicated to have negative association with depression. However, few studies were published for the evidence association together with the consideration of SES and job stress factors. The current study is a part of the Japanese study of Health, Occupation and Psychosocial factors related Equity (J-HOPE study) that focused on the association of social stratification and health and our objective was to clarify the association between folate intake and depressive symptoms in Japanese general workers. Subjects were 2266 workers in a Japanese nationwide company. SES and job stress factors were assessed by self-administered questionnaire. Folate intake was estimated by a validated, brief, self-administered diet history questionnaire. Depressive symptoms were measured by Kessler's K6 questionnaire. "Individuals with depressive symptoms" was defined as K6≥9 (in K6 score of 0-24 scoring system). Multiple logistic regression and linear regression model were used to evaluate the association between folate and depressive symptoms. Several SES factors (proportion of management positions, years of continuous employment, and annual household income) and folate intake were found to be significantly lower in the subjects with depressive symptom (SES factors: p < 0.001; folate intake: P = 0.001). There was an inverse, independent linear association between K6 score and folate intake after adjusting for age, sex, job stress scores (job strains, worksite supports), and SES factors (p = 0.010). The impact of folate intake on the prevalence of depressive symptom by a multiple logistic model was (ORs[95% CI]: 0.813 [0.664-0.994]; P =0.044). Our cross-sectional study suggested an inverse, independent relation of energy-adjusted folate intake with depression score and prevalence of depressive symptoms in Japanese workers, together with the consideration of SES and job stress factors.

To determine the relationship between depressive symptoms and dependence in activities of daily living. Participants, aged 70 to 104 (n= 1 880), were evaluated twice (2001 and 2003). Depressive symptoms were established by a modified version of Center for Epidemiologic Studies Depression scale, whereas functional dependence was assessed with Lawton & Brody and Katz scales. Dependence implies the attendance and assistance of another person to accomplish the activity. Multivariate regression analyses were used to determine the effect of depressive symptoms on incident dependence. At baseline, 37.9% had depressive symptoms. After two years, 6.1 and 12.7% developed functional dependence for one or more ADL and IADL, respectively. Multivariate analyses showed that depressive symptoms were a risk factor to the development of functional dependence only for the instrumental activities for daily living. Depressive symptoms are a risk factor for functional dependence. Systematic screening it seems necessary in the evaluation of geriatric patients.

Depression in adolescence

2012-01-01

Unipolar depressive disorder in adolescence is common worldwide but often unrecognised. The incidence, notably in girls, rises sharply after puberty and, by the end of adolescence, the 1 year prevalence rate exceeds 4%. The burden is highest in low-income and middle-income countries. Depression is associated with sub stantial present and future morbidity, and heightens suicide risk. The strongest risk factors for depression in adolescents are a family history of depression and exposure to psychosocial stress. Inherited risks, developmental factors, sex hormones, and psychosocial adversity interact to increase risk through hormonal factors and associated perturbed neural pathways. Although many similarities between depression in adolescence and depression in adulthood exist, in adolescents the use of antidepressants is of concern and opinions about clinical management are divided. Effective treatments are available, but choices are dependent on depression severity and available resources. Prevention strategies targeted at high-risk groups are promising. PMID:22305766

Depression can be prevented if its symptoms are addressed early and effectively. Prevention against depression among university students is rare in the Philippines, but is urgent because of the rising rates of suicide among the group. Evidence is needed to systematically identify and assist students with higher levels of depressive symptoms. We carried out a survey to determine the social and demographic factors associated with higher levels of depressive symptoms among 2,436 Filipino university students. The University Students Depression Inventory with measures on lethargy, cognition-emotion, and academic motivation, was used. Six of the 11 factors analyzed were found to be statistically significantly associated with more intense levels of depressive symptoms. These factors were: frequency of smoking, frequency of drinking, not living with biological parents, dissatisfaction with one’s financial condition, level of closeness with parents, and level of closeness with peers. Sex, age category, course category, year level and religion were not significantly related. In identifying students with greater risk for depression, characteristics related to lifestyle, financial condition, parents and peers are crucial. There is a need to carry out more surveys to develop the pool of local knowledge on student depression. PMID:24223198

Depressive personality disorder, dysthymia, and their relationship to perfectionism.

This paper reports the results of two studies in a nonclinical (n=105) and primary care outpatient sample (n=110), in which Depressive Personality Disorder (DPD), Dysthymia, and depression were assessed for their distinctive relationship with perfectionism. Results from both studies found that self-reported DPD, Dysthymia, and depressive symptoms were all intercorrelated, and that DPD, Dysthymia, and depressive symptoms were correlated with three dimensions of perfectionism-Concern over Mistakes, Doubts about Actions, and Parental Criticism. In the nonclinical sample, variance in measures of DPD was predicted by measures of perfectionism after controlling for depression and Dysthymia symptoms. A similar pattern of findings was observed in the primary care sample. This relationship with perfectionism did not occur when Dysthymia or depressive symptoms were predicted. Nevertheless, much of the variance in measures of DPD, Dysthymia, and depressive symptoms is associated with each other and not perfectionism. It is concluded that a common factor or set of factors underlies these disorders, but that DPD may be more strongly related to perfectionism than Dysthymia and depression. As a common factor(s) is identified, measures of DPD and Dysthymia may be refined, thereby increasing the discriminant validity of their measures.

This study aimed to examine the prevalence of depression symptoms and risk factors by gender among rice farmers in Nakhon Ratchasima Province in Thailand. A cross-sectional study was designed using interviewed questionnaire on lifestyle, work, and depression symptoms. To examine the factors associated with depression symptoms, multiple logistic regression analysis was used. Depression symptoms were found in 39.0% of males and 48.1% of females. Eating healthy food, preparing to prevent the problem, having community integration, hearing loud machines, and using personal protective equipment during work with chemical substances were associated factors among males with depression symptoms. Having family connection, being an accepted person in community, hearing loud machines, and having work-related financial hardship were predictors among females with depression symptoms. The prevalence of depression symptoms among Thai rice farmers was high. To prevent mental health problems, it is important to give males the support for health action and working styles, and females an accepting atmosphere. Corresponding to the aim, we have to define the factor by gender. © 2015 APJPH.

Over the years, the number of international university students has been increasing in the Philippines. Depression tends to be common among this demographic sector, because of the varying challenges and expectations associated with studying abroad. Depression can be prevented if its symptoms, particularly those at higher levels, are identified and addressed early and effectively. This survey examined the social and demographic factors that are significantly associated with higher levels of depressive symptoms. One hundred twenty-six international university students were interviewed using the University Students Depression Inventory. Of the 13 factors analyzed, 3 were found with statistically significant associations with more intense levels of depressive symptoms. These factors were: level of satisfaction with one's financial condition, level of closeness with parents, and level of closeness with peers. In identifying international students with greater risk for depression, characteristics related to their financial condition and primary group relationships can be considered. There is a need to carry out more studies to confirm this initial evidence. The findings can help guide further discourse, research and program to benefit international students with higher levels of depressive symptoms.

Background Preschool-onset depression, a developmentally adapted form of depression arising between the ages of 3–6, has demonstrated numerous features of validity including characteristic alterations in stress reactivity and brain function. Notably, this validated syndrome with multiple clinical markers is characterized by sub-threshold DSM Major Depressive Disorder criteria, raising questions about its clinical significance. To clarify the utility and public health significance of the preschool-onset depression construct, diagnostic outcomes of this group at school age and adolescence were investigated. Methods We investigated the likelihood of meeting full DSM Major Depressive Disorder criteria in later childhood (i.e., ≥ age 6) as a function of preschool depression, other preschool Axis I disorders, maternal depression, parenting non-support and traumatic life events in a longitudinal prospective study of preschool children. Results Preschool-onset depression emerged as a robust predictor of DSM-5 Major Depressive Disorder in later childhood even after accounting for the effect of maternal depression and other risk factors. Preschool-onset conduct disorder also predicted DSM-5 Major Depressive Disorder in later childhood, but this association was partially mediated by maternal non-support, reducing the effect of preschool conduct disorder in predicting DSM depression by 21%. Discussion Study findings provide evidence that this preschool depressive syndrome is a robust risk factor for meeting full DSM criteria for Major Depressive Disorder in later childhood over and above other established risk factors. Preschool conduct disorder also predicted Major Depressive Disorder but was mediated by maternal non-support. Findings suggest that attention to preschool depression and conduct disorder in addition to maternal depression and exposure to trauma should now become an important factor for identification of young children at highest risk for later MDD who should be targeted for early interventions.

BACKGROUND Although research suggests depression is common among individuals with Parkinson’s disease (PD), it is unclear how to best assess depression in PD (dPD). We wanted to examine the prevalence of dPD using different definitions of depression, as well as examine factors associated with dPD. METHODS One hundred fifty-eight individuals (68% male; age 66.8 ± 9.6 SD) with a primary diagnosis of PD were assessed for depression using the Harvard Department of Psychiatry/National Depression Screening Day Scale (HANDS) in an outpatient setting at the Movement Disorders Clinic at Massachusetts General Hospital. We defined depression using 4 thresholds based on the HANDS and whether or not an individual was ever on an antidepressant regimen. We also examined potential predictors of the presence of dPD. RESULTS The prevalence of depression among study participants ranged from 11% to 57%, depending on which of the 4 definitions of depression was applied. Younger age and longer duration of PD predicted a relatively higher prevalence of depression. Having a history of depression prior to onset of PD also was predictive of dPD. CONCLUSIONS Depression appears to be relatively common among individuals with PD, and history of depression, younger age, and longer PD duration may be factors associated with dPD. PMID:21808748

Postpartum depression is one of the major causes of disability among women who are on their childbearing years. Identifying people at risk of postpartum depression may improve its management. The objective of this study was to determine the probable association between postpartum depression and some preconception gynecological morbidities. Data from a nationwide birth cohort study, the Japan Environment and Children's study (JECS), up to one month of postpartum were analyzed. To assess postpartum depression, the Edinburgh Postnatal Depression Scale (EPDS) was used; 11 preconception gynecological morbidities were considered as risk factors. Covariates included psychiatric illness history, psychosocial factors, some pregnancy adverse outcomes, birth outcomes, socio-demographic and health behavioral factors. Except for the prevalence of previous miscarriage, leiomyoma and polycystic ovarian syndrome, depressive women had more gynecological morbidities compared to non-depressive ones. In logistic regression model, endometriosis (OR, 1.27; 95%CI: 1.15-1.41), dysmenorrhea (OR, 1.13; 95%CI: 1.06-1.21) and abnormal uterine bleeding (OR, 1.21; 95%CI: 1.15-1.29) were associated with postpartum depression. CONCLUSION: Women with endometriosis and menstrual problems were at risk of developing postpartum depression. This study suggests a perinatal mental health screening for predisposed women.

Spence, Susan H; Najman, Jake M; Bor, William; O'Callaghan, Michael J; Williams, Gail M

2002-05-01

This paper examines the degree to which symptoms of anxiety and depression at age 14 years are associated with early childhood experience of maternal anxiety and depression, poverty, and mother's marital relationship distress and break-up. In a longitudinal study, 4434 families were followed-up from infancy to adolescence. Maternal anxiety and depression during early childhood were found to have small, but significant, influences upon the development of high anxiety-depression symptoms at age 14, after controlling for the effects of poverty and marital relationship factors. This effect was greater with repeated exposure to high maternal anxiety and depression. Poverty, distressed marital relationship and marital break-up during the child's first five years also produced small, but significant, increases in risk of high anxiety and depression symptoms in adolescence. Stable, single-parent status was not found to be a risk factor. There was no evidence of marked gender differences in risk factors, other than poverty, which had a stronger impact for girls than boys. Overall, the results suggest that maternal anxiety and depression, poverty, parent relationship conflict and marital break-up during early childhood are associated with small, but significant, increased risk of anxiety-depression symptoms in adolescence.

Depression is associated with an increased likelihood of cardiac events and stroke. We hypothesized that the vascular risk factor burden might itself predispose to both cardiovascular events and depression. Therefore, we examined whether aggregate scores of vascular risk factor burden were associated with the new-onset of depression in the community. We studied 2023 depression- and dementia-free Framingham Heart Study (Framingham, USA) Offspring participants who attended both examination cycles 7 (1998-2001) and 8 (2005-2008). The American Heart Association Ideal Cardiovascular Health metric and the Framingham stroke risk profile were calculated at exam seven. New-onset depression was adjudicated at examination cycle eight as antidepressant medication use or Centre for Epidemiologic Studies Depression Scale scores ≥16, after a mean follow-up of 6.6years (standard deviation=0.7). Of the 2023 participants, 269 (13%) developed new-onset depression. Following adjustments for age, sex, education, and the time interval between baseline and follow-up, the odds of new-onset depression decreased by 10% for each one-point increase in ideal cardiovascular health scores (Odds Ratio [OR], 0.90; 95% confidence interval [CI] 0.81-0.99) and increased by 4% for each percentage point increase in the Framingham stroke risk profile (OR, 1.04; CI, 1.00-1.07). Results were not explained by interim clinical stroke or cerebral white matter injury. In conclusion, vascular risk factor burden was associated with the new onset of depression. Shared vascular risk factors may contribute to the increased risk of cardiovascular events observed in persons with depression. Copyright © 2017 Elsevier Inc. All rights reserved.

Integrating etiological models of social anxiety and depression in youth: evidence for a cumulative interpersonal risk model.

PubMed

Epkins, Catherine C; Heckler, David R

2011-12-01

Models of social anxiety and depression in youth have been developed separately, and they contain similar etiological influences. Given the high comorbidity of social anxiety and depression, we examine whether the posited etiological constructs are a correlate of, or a risk factor for, social anxiety and/or depression at the symptom level and the diagnostic level. We find core risk factors of temperament, genetics, and parent psychopathology (i.e., depression and anxiety) are neither necessary nor sufficient for the development of social anxiety and/or depression. Instead, aspects of children's relationships with parents and/or peers either mediates (i.e., explains) or moderates (i.e., interacts with) these core risks being related to social anxiety and/or depression. We then examine various parent- and peer-related constructs contained in the separate models of social anxiety and depression (i.e., parent-child attachment, parenting, social skill deficits, peer acceptance and rejection, peer victimization, friendships, and loneliness). Throughout our review, we report evidence for a Cumulative Interpersonal Risk model that incorporates both core risk factors and specific interpersonal risk factors. Most studies fail to consider comorbidity, thus little is known about the specificity of these various constructs to depression and/or social anxiety. However, we identify shared, differential, and cumulative risks, correlates, consequences, and protective factors. We then put forth demonstrated pathways for the development of depression, social anxiety, and their comorbidity. Implications for understanding comorbidity are highlighted throughout, as are theoretical and research directions for developing and refining models of social anxiety, depression, and their comorbidity. Prevention and treatment implications are also noted.

This survey study aims to examine the prevalence and factors associated with depressive symptoms among primary older female family carers of adults with intellectual disabilities (ID). In total, 350 female family carers aged 55 and older took part and completed the interview in their homes. The survey package contained standardised scales to assess carer self-reported depressive symptoms, social support, caregiving burden and disease and health, as well as adult and carer sociodemographic information. Multiple linear regressions were used to identify the factors associated with high depressive symptoms in carers. Between 64% and 72% of these carers were classified as having high depressive symptoms. The factors associated with carer self-reported depressive symptoms were carer physical health, social support and caregiving burden; overall, the carer self-reported physical health was a stronger factor associated with depressive symptoms than their physical disease status. The level of the adult with ID's behavioural functioning and the carer age, marital status, employment status, education level and the family income level were not significantly associated with carer depressive symptoms. The factors identified in this study as correlating with self-reported depressive symptoms suggest that researchers and mental health professionals should collaborate to help improve the physical health and social support networks of the most vulnerable older female family carers. This should reduce depressive symptoms directly among this high-risk group. © 2010 The Authors. Journal of Intellectual Disability Research © 2010 Blackwell Publishing Ltd.

To evaluate the factors associated with depressive symptoms in a sample of Nigerian 13-18-year-olds attending senior secondary schools. Adolescents aged 13 to 18 years (n = 1095) attending senior secondary schools completed the Beck Depressive Inventory (BDI) as a measure of their depressive symptoms. The adolescents and their parents also completed various questionnaires regarding related demographic, psychosocial and family factors. There were 99 (9.0%) adolescents with clinically significant depressive symptoms. The factors significantly associated with adolescents' depressive symptoms include parental depressive symptoms (odds ratio [OR] 5.21, 95% confidence interval [CI] 3.48-7.81), adolescents' perception of family functioning as poor (OR 6.79, 95% CI 3.46-12.23), adolescents' problems with peers (OR 4.69, 95% CI 3.06-7.19), adolescents' low self-esteem (OR 6.63, 95% CI 2.59-16.96), adolescents' drinking (OR 3.98, 95% CI 2.37-6.69), female gender (OR 1.74, 95% CI 1.11-2.72), and large family size (OR 2.83, 95% CI 1.15-7.74). Child and adolescent health policy-makers should consider these factors when planning healthcare services or formulating a predictive model for adolescents' depression in low-income countries. Clinical assessment should focus on identification of these variables and nonpharmacological interventions may be of relevance in addressing some of the associated factors.

Neural activity in relation to empirically derived personality syndromes in depression using a psychodynamic fMRI paradigm

2013-01-01

Objective: The heterogeneity between patients with depression cannot be captured adequately with existing descriptive systems of diagnosis and neurobiological models of depression. Furthermore, considering the highly individual nature of depression, the application of general stimuli in past research efforts may not capture the essence of the disorder. This study aims to identify subtypes of depression by using empirically derived personality syndromes, and to explore neural correlates of the derived personality syndromes. Materials and Methods: In the present exploratory study, an individually tailored and psychodynamically based functional magnetic resonance imaging paradigm using dysfunctional relationship patterns was presented to 20 chronically depressed patients. Results from the Shedler–Westen Assessment Procedure (SWAP-200) were analyzed by Q-factor analysis to identify clinically relevant subgroups of depression and related brain activation. Results: The principle component analysis of SWAP-200 items from all 20 patients lead to a two-factor solution: “Depressive Personality” and “Emotional-Hostile-Externalizing Personality.” Both factors were used in a whole-brain correlational analysis but only the second factor yielded significant positive correlations in four regions: a large cluster in the right orbitofrontal cortex (OFC), the left ventral striatum, a small cluster in the left temporal pole, and another small cluster in the right middle frontal gyrus. Discussion: The degree to which patients with depression score high on the factor “Emotional-Hostile-Externalizing Personality” correlated with relatively higher activity in three key areas involved in emotion processing, evaluation of reward/punishment, negative cognitions, depressive pathology, and social knowledge (OFC, ventral striatum, temporal pole). Results may contribute to an alternative description of neural correlates of depression showing differential brain activation dependent on the extent of specific personality syndromes in depression.

Depression is common in people with Alzheimer's disease (AD), and is associated with increased risk of institutionalization and mortality. Understanding risk factors for depression in AD is key to its development and treatment. We searched the MEDLINE, EMBASE, PsycINFO, and CINAL databases for longitudinal prospective cohort studies that evaluated risk factors for depression in people with AD. Two authors independently selected articles for inclusion and assessed quality of studies using predetermined criteria. In seven studies that met the inclusion criteria, 2029 participants were followed up for a median of 5 years. Gender and educational attainment were not predictors of depression risk. History of a past psychiatric disorder and greater cognitive impairment predicted increased risk of depression in more than one study. In single studies, younger age, having a family history of psychiatric disorder, neuroticism, functional decline, presence of sleep disturbance and aggression, and increased cardiovascular risk predicted depression risk. Not being within 6 months of dementia onset and, counterintuitively having two comorbid disorders were protective factors in one study. A small number of studies exist overall and only a few have examined the same risk factors. Most of the studies have measured depression using scales that are not validated in AD. These results inform a preliminary model of depression risk in people with AD. Unlike in the general population, men and women and those with higher and lower educational levels of attainment may be equally at risk of depression. Clinicians should be aware of these possible differences in the risk profile for depression in AD populations, to assist detection and enable early treatment. Interventions to delay cognitive and functional decline may reduce depression risk. Copyright © 2018 Elsevier B.V. All rights reserved.

This article seeks to review and discuss the evidence linking depression, coronary heart disease (CHD), and culture. PsychInfo, CINAHL, PubMed, and Google were searched for pertinent evidence linking depression, culture, and CHD, and retrieved articles were analyzed using thematic content analysis. Identified themes were the followings: depression is a factor in development and prognosis of CHD and affects the capacity to self-manage and adhere to treatment recommendations; culture mediates mental health/illness representations and treatment-seeking behaviors; screening and assessment of depression can be affected by cultural factors; and there is a need for culturally appropriate screening and therapeutic strategies. As depression is a predictor and moderating variable in the genesis and progression of CHD, understanding how factors such as culture affect screening and management of the disease is important to inform the development of culturally and linguistically competent strategies that ensure accurate screening, detection, and treatment of depression in cardiac patients in clinical practice. © The Author(s) 2014.

To investigate the prevalence and possible influencing factors of depressive disorder in surgical inpatients. Two hundred and sixty-six surgical inpatients meeting the inclusion criteria were first screened with the self rating depression scale (SDS), and then the subjects screened positive and 20% of those screened negative were evaluated with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) as a gold standard for diagnosis of depressive disorder. Possible influencing factors were also analyzed by experienced psychiatrists. The standard score of SDS in the surgical inpatients were significantly higher than those in the Chinese norm, and the incidence of depressive disorder in the surgical inpatients was 37.2%. Unvaried analysis showed that depressive disorder were associated with gender, education, economic condition, variety of diseases, hospitalization duration, and treatment methods. Logistic regression analysis revealed that gender, economic condition, treatment methods and previous history were the main influencing factors. The incidence of depressive disorder in the surgical inpatients is high, and it is mainly influenced by gender, economic condition, treatment methods and previous history.

The present study examines the association between disease-related factors, perceived social support, attachment security (i.e. attachment anxiety and avoidance), and the occurrence of depressive symptoms in a sample of patients with metastatic gastrointestinal or lung cancer. Results from a sample of 326 cancer outpatients with advanced disease indicate that disease-related factors are significantly associated with the occurrence of depressive symptoms, and the latter are inversely related to the degree of attachment anxiety and avoidance, and perceived social support. Attachment security (on the dimension of anxious attachment) significantly buffered the effect of disease-related factors on depressive symptoms, and perceived social support mediated the relationship between attachment security and depressive symptoms. The buffering effect of attachment security on depressive symptoms and its partial mediation through social support suggest that the interaction of individual, social, and disease-related factors contribute to the emergence of depressive symptoms in patients with metastatic cancer.

The relationship between perceived discrimination and depressive symptoms among older black American populations is poorly understood. Although a small number of studies have examined the relationship between stress and social support, few have examined the association between perceived discrimination, social networks, and depressive symptoms among a representative sample of older racial and ethnic groups. This study examines (a) the relationship between sociodemographic factors, perceived discrimination and depressive symptoms and (b) social networks as a potential moderator in the perceived discrimination and depressive symptom relationship between 2 groups of older black Americans. This was a cross-sectional study using data from the National Survey of American Life with a sample of older African Americans (N = 837) and Caribbean blacks (N = 271). Depressive symptoms were assessed using the 12-item Center for Epidemiological Studies Depression scale. Linear regression analyses were used to predict depressive symptoms. The relationship between perceived discrimination and depressive symptoms was significant in both groups. Social networks contributed as a protective factor for depressive symptoms for both groups. However, there was no significant moderation effect. Results suggest that regardless of ethnic affiliation, the experience of perceived discrimination is similar in both groups and is a risk factor for depressive symptoms. Future research is needed in this area to better understand the associations between sociodemographic factors, perceived discrimination, social networks, and their impact on depressive symptoms.

Background and Objective: Depression is one of the most common and specific problems during pregnancy and after it. Maternal postpartum depression compromises mother's health and affects social relationship, and has negative effect on infant development. The aim of this study was to investigate the prevalence of postpartum depression and its related factors in Isfahanian mothers. Materials and Methods: This is a cross - sectional study. The study populations were 133 women who at the last 8-4 weeks of labor referred to Isfahan health centers. Demographic information and obstetric and Beck Depression Inventory were applied. Three categories emerged according to the degree of scale: Mild, moderate, and severe depression. Statistical analysis was used with the Pearson correlation and linear regression in SPSS version 18. Results: A total of 73 mothers had mild depression (10-19) and 56 had moderate depressions (20-29). Among the factors related to depression such as maternal education, financial status, unwanted pregnancy, premenstrual syndrome, and maternal occupational history, there was a significant correlation with postpartum depression (P > 0.05). Variables in the regression analysis include maternal education, financial status, unwanted pregnancy, history of premenstrual syndrome, maternal occupation, type of delivery, history of miscarriage, and having a satisfaction with baby gender. And, a total of 27.7% variance explains the postpartum depression. Among these factors, the predictive variables of maternal education, type of delivery, financial condition, unwanted pregnancy, premenstrual syndrome, and maternal occupational history were significant in the meantime; the prediction of unplanned pregnancy was more than other variables (ß = 0.24). Conclusions: With attention to factors associated with postpartum depression, the healthcare planner will help to better manage the problem. The results of this study will help to better understand the factors influencing mothers in the labor process, and mothers in the labor process, experiences minimum mental health disorders.

Recent longitudinal data suggest a close association between depression and lifestyle. Little work to date has estimated the prevalence of depression in the nursing workforce in China, nor considered what lifestyle factors might be correlated with it-a gap filled by the present study. The study's web-based cross-sectional survey solicited data from qualified nurses aged between 21 and 65 registered with the Hong Kong Nursing Council. The Depression, Anxiety and Stress Scale 21 was used to measure 850 nurses for depression, anxiety and symptoms of stress; a generalized linear regression model examined associations between lifestyle factors and depression. Mean depression symptom scores show a downward linear trend for male and female participants. Gender and age, however, did not emerge as significant predictors of depression. Three lifestyles factors (sleep, entertainment and hobbies) showed a significant association with depression. Nurses should make therapeutic lifestyle changes to improve their work-life balance and safeguard their functioning at work and personal well-being.

Childhood abuse makes people vulnerable to developing depression, even in late life. Psychosocial factors that are common in late life, such as loneliness or lack of a partner, may explain this association. Our aim was to investigate whether the association between childhood abuse and depression in older adults can be explained by psychosocial factors. Cross-sectional data were derived from the Netherlands Study of Depression in Older Persons (aged 60-93), including 132 without lifetime depression, 242 persons with an early-onset depression (<60 years), and 125 with a late-onset (≥60 years) depression. Childhood abuse (yes/no) and a frequency-based childhood abuse index were included. Multinomial regression and multivariable mediation analyses were used to examine the association between childhood abuse and the onset of depression, and the influence of loneliness, social network, and partner status. Multinomial regression analyses showed a significant association between childhood abuse and the childhood abuse index with early- and late-onset depression. Multivariable mediation analyses showed that the association between childhood abuse and early-onset depression was partly mediated by social network size and loneliness. This was particularly present for emotional neglect and psychological abuse, but not for physical and sexual abuse. No psychosocial mediators were found for the association between childhood abuse and late-onset depression. A smaller social network and feelings of loneliness mediate the association between childhood abuse and early-onset depression in older adults. Our findings show the importance of detecting childhood abuse as well as the age at depression onset and mapping of relevant psychosocial factors in the treatment of late-life depression.

Abstract Depressive symptoms are related to negative health outcomes in caregivers of patients with HF. Understanding the factors that are associated with depressive symptoms among caregivers is essential to providing appropriate interventions. Little is known about which status and factors are related to depressive symptoms among Chinese caregivers of patients with heart failure. This study aimed to investigate the status of depressive symptoms and to identify the factors that are associated with depressive symptoms in family caregivers of patients with heart failure in China. A cross-sectional design and a convenience sample were used. Participants (N = 134) from 1 hospital in Chengdu were recruited from June 2013 to June 2014. The following measurement tools were used in this study: Center for Epidemiologic Studies Depression Scale, Hospital Anxiety and Depression Scale, Coping Strategies Simplified Coping Style Questionnaire, and Zarit Burden Interview. A hierarchical multiple linear regression analysis was used to determine which factors were associated with depressive symptoms. The results showed that 31% of the caregivers experienced depressive symptoms. The type of payment for treatment (b = −0.312, P < 0.01), readmissions within the last 3 months (b = 0.397, P < 0.01), duration of caregiving (b = −0.213, P < 0.05), caregiver burden (b = 0.299, P < 0.05), active coping (b = −0.235, P < 0.01), and negative coping (b = 0.245, P < 0.05) were related to caregivers’ depressive symptoms. Fifty-four percent of the variance in caregivers’ depressive symptoms was explained by these factors. The caregiver depressive symptoms in China were higher than those reported in studies that were conducted in Western countries. Caregiver depressive symptoms can be improved by providing support for new caregivers (with a caregiving duration of less than 1 year), reducing readmissions, easing caregiver burden, and promoting their coping strategies.

To explore the factors related to quality of life for patients with type 2 diabetes with or without depressive symptoms in China. In patients with type 2 diabetes with or without depressive symptoms, different factors such as gender, social context or regional setting may affect their quality of life. This was a cross-sectional study. Of 791 registered patients with type 2 diabetes from four communities in Beijing, cluster sampling was used to recruit patients for participation. Self-rating depression scale was used to screen for depressive symptoms; demographic and clinical data were collected, and quality of life and social support were assessed using appropriate tools. The factors associated with quality of life were tested using multivariate linear regression. The prevalence of depressive symptoms in 667 patients with diabetes was 44·2%. Quality of life of patients with depressive symptoms was worse than that of patients without depressive symptoms, and this was associated negatively with history of diabetic complications, usage of hypoglycaemic agents or insulin and self-rating depression scale scores and positively with salary and subjective social support. The factors related to quality of life for patients with or without depressive symptoms are different. For patients with depressive symptoms, better salary and subjective social support are associated positively with their quality of life, while the presence of diabetic complications, a higher score for depressive symptoms and need for hypoglycaemic agents or insulin are negatively associated with quality of life. It is suggested that the nurse should screen depression for patients with diabetes, especially for those with diabetic complications or low social support. This should be done in the community regularly in order to find diabetic patients with depression in time. In addition, the results can provide a reference to clinical nursing care for patients with diabetes in hospitals. © 2012 Blackwell Publishing Ltd.

Context Although the prevalence of depression among medical interns substantially exceeds that of the general population, the specific factors responsible are not well understood. Recent reports of a moderating effect of a genetic polymorphism (5-HTTLPR) in the serotonin transporter protein gene on the likelihood that life stress will precipitate depression may help to understand the development of mood symptoms in medical interns. Objective To identify psychological, demographic and residency program factors that associate with depression among interns and use medical internship as a model to study the moderating effects of this polymorphism using a prospective, within-subject design that addresses the design limitations of earlier studies. Design Prospective cohort study Setting 13 United States hospitals Participants 740 interns entering participating residency programs Main outcome measures Subjects were assessed for depressive symptoms using the Patient Health Questionnaire (PHQ-9), a series of psychological traits and 5-HTTLPR genotype prior to internship and then assessed for depressive symptoms and potential stressors at 3-month intervals during internship. Results The PHQ-9 depression score increased from 2.4 prior to internship to a mean of 6.4 during internship (p<0.001). The proportion of participants who met PHQ-9 criteria for depression increased from 3.9% prior to internship to a mean of 25.7% during internship (p<0.001). A series of factors measured prior to internship (female sex, U.S. medical education, difficult early family environment, history of major depression, lower baseline depressive symptom score and higher neuroticism) and during internship (increased work hours, perceived medical errors and stressful life events) were associated with a greater increase in depressive symptoms during internship. In addition, subjects with at least one copy of a less transcribed 5-HTTLPR allele reported a greater increase in depressive symptoms under the stress of internship (p=0.002). Conclusions There is a marked increase in depressive symptoms during medical internship. Specific individual, internship and genetic factors are associated with the increase in depressive symptoms.

Beseler, Cheryl Lynn; Stallones, Lorann

2006-01-01

To use structural equation modeling (SEM) to test the theory that a past pesticide poisoning may act as a mediator in the relationship between depression and safety practices. Depression has been associated with pesticide poisoning and was more strongly associated with safety behaviors than workload, social support or health status of farm residents in a previously published report. A cross-sectional survey of farmers and their spouses was conducted in eight counties in northeastern Colorado. Depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression (CES-D) scale. Exploratory and confirmatory factor analyses were used to identify symptoms most correlated with risk factors for depression and safety practices. SEM was used to examine theoretical causal models of the relationship between depression and poor health, financial difficulties, a history of pesticide poisoning, and safety practices. Exploratory factor analysis identified three factors in the CES-D scale. The SEM showed that poor health, financial difficulties and a history of pesticide poisoning significantly explained the depressive symptoms. Models with an excellent fit for the safety behaviors resulted when modeling the probability that the pesticide poisoning preceded depression, but no fit was possible when reversing the direction and modeling depression preceding pesticide poisoning. Specific depressive symptoms appeared to be significantly associated with primarily animal handling and farm machinery. The order of events, based on SEM results, was a pesticide poisoning preceding depressed mood in relation to safety behaviors.

Difficult living conditions in urban areas could result in an increased risk of developing depression, particularly among women. One of the strong predictors of depression is poverty, which could lead to inequality in risk of depression. However, previous studies found conflicting results between poverty and depression. This study examines whether depression was unequally distributed among young and middle-adult women in Indonesia׳s major cities and investigate the factors contributed to the inequality. Data from 1117 young and middle-adult women in Indonesia׳s major cities (Jakarta, Surabaya, Medan, and Bandung) were analysed. Concentration Index (CI) was calculated to measure the degree of the inequality. The CI was decomposed to investigate the factor contributing most to the inequality. The prevalence of depression was 15% and more concentrated among lower economic group (CI=-0.0545). Compared to the middle-adult group, the prevalence of depression among women in the young-adult group was significantly higher (18% vs 11%, p<0.05) and more equally distributed (CI=-0.0343 vs CI=-0.1001). Household consumption expenditure was the factor that contributed most to inequality in both group. Other factors contributing to inequality were smoking in young-adult group and marital status in middle-adult group. Contribution of education to inequality varied for different age groups. Depression is more concentrated among the lower economic groups, with household expenditure being the major factor contributing to the inequality. This finding emphasises the importance of primary care level mental health services, particularly in poorer urban communities. This study is based on a cross-sectional data, and only assesses social determinants of depression. These determinants are important to address in addition to biological determinants and other factors. Copyright © 2015 Elsevier B.V. All rights reserved.

Prenatal Predictors of Maternal Attachment and Their Association with Postpartum Depressive Symptoms in Mexican Women at Risk of Depression.

2017-06-01

Objectives Although maternal attachment is an important predictor of infant developmental outcomes, little is known about its pre- and postnatal predictors. The purpose of this secondary data analysis is to assess several risk factors for maternal attachment at 6 months postpartum in a sample of Mexican women at risk of depression. The predictors included were prenatal depressive symptoms, pregnancy intendedness, partner relationship, social support, maternal history of childhood sexual abuse, and postpartum depressive symptoms. Methods A total of 156 pregnant women seeking antenatal care at three health centers were selected because they displayed depressive symptoms (CES-D ≥ 16) or had previously suffered depression. Women were interviewed during pregnancy and at 6 months postpartum. A step-wise multivariate logistic regression was conducted to evaluate the pre- and postpartum risk factors for postpartum depression related to low maternal attachment. Results Pre- and postpartum depressive symptoms increased the risk of low maternal attachment by factors of 3.00 and 3.97, respectively, compared with women who did not present these symptoms; low level of adjustment with the partner increased the risk by a factor of 3.11, low social support by a factor of 2.90, and CSA by a factor of 2.77. Conclusions for practice Prevention programs during pregnancy to reduce depressive symptoms should strengthen strategies to promote maternal attachment by improving partner relations and increasing social support. However, evidence shows that such programs alone are insufficient, so direct interventions should also be implemented. Women with a history of childhood sexual abuse should be given additional attention during prenatal care.

Recent work on comorbidity finds evidence for hierarchical structure of mood and anxiety disorders and symptoms. This study tests whether a higher-order internalizing factor accounts for variation in depression and anxiety symptom severity and change over time in a sample experiencing a period of major life stress. Data on symptoms of depression, chronic worry and social anxiety were collected 5 times across 7 months from 426 individuals who had recently lost jobs. Growth models for each type of symptom found significant variation in individual trajectories. Slopes were highly correlated across symptom type, as were intercepts. Multilevel confirmatory factor analyses found evidence for a higher-order internalizing factor for both slopes and intercepts, reflective of comorbidity of depression and anxiety, with the internalizing factor accounting for 54% to 91% of the variance in slopes and intercepts of specific symptom sets, providing evidence for both a general common factor and domain-specific factors characterizing level and change in symptoms. Loadings on the higher order factors differed modestly for men and women, and when comparing African-American and White participants, but did not differ by age, education, or history of depression. More distal factors including gender and history of depression were strongly associated with internalizing in the early weeks after job loss, but rates of change in internalizing were associated most strongly with reemployment. Findings suggest that stressors may contribute in different ways to the common internalizing factor as compared to variance in anxiety and depression that is independent of that factor.

The aim of this study was to complete the identification of predictive factors of depression during adolescence. For some authors, depression is characterized by a style of attribution, which consists essentially in attributing most of the negative outcomes to internal, stable, and uncontrollable factors. It seems that these attributions depend essentially on the type of their beliefs and in particular, those concerning the nature of intelligence. These beliefs called "implicit theories of intelligence", are the entity theory of intelligence and the incremental theory of intelligence. The entity theory of intelligence corresponds to the belief according to which intelligence is the expression of a relatively stable, fixed, and noncontrollable feature, and which we cannot change. In contrast, the incremental theory corresponds to the belief according to which intelligence is a controllable quality, which we can develop through effort and work. Several studies have demonstrated that the adolescents who consider intelligence as a malleable quality explain their bad results by internal, unstable, and controllable factors. Conversely, students who consider intelligence as a fixed capacity tend to strongly attribute their failure to internal, stable, and uncontrollable factors. We have consequently formulated the hypothesis according to which the entity theory should be a predictive factor of depression. We have also tested the fact that anxiety should be a mediating factor within the relation between the entity theory and depression. The sample was composed of 424 adolescents. Using different questionnaires, we measured implicit theories of the intelligence (TIDI), self-esteem (EES), anxiety (STAI-Form Y-B) and depression (CDI). Multiple regression analyses demonstrated that the entity theory of intelligence positively predicts depression. Self-esteem negatively predicts anxiety and depression. Moreover, anxiety is a mediator of the relation between self-esteem and depression, on one hand, and the relation between the entity theory of intelligence and depression, on the other. Finally, the effect of the entity theory of intelligence appears to be modulated by the level of self-esteem. This study explains the mechanisms by which the implicit theories of intelligence engender anxiety and depression. Furthermore, this approach provides interesting perspectives in the prevention and management of adolescents presenting depression.

Population characteristics of submicrometer-sized craters on regolith particles from asteroid Itokawa

We investigated impact crater structures on regolith particles from asteroid Itokawa using scanning electron microscopy. We observed the surfaces of 51 Itokawa particles, ranging from 15 μm to 240 μm in size. Craters with average diameters ranging from 10 nm to 2.8 μm were identified on 13 Itokawa particles larger than 80 μm. We examined the abundance, spatial distribution, and morphology of approximately 900 craters on six Itokawa particles. Craters with sizes in excess of 200 nm are widely dispersed, with spatial densities from 2.6 μm2 to 4.5 μm2; a fraction of the craters was locally concentrated with a density of 0.1 μm2. The fractal dimension of the cumulative crater diameters ranges from 1.3 to 2.3. Craters of several tens of nanometers in diameter exhibit pit and surrounding rim structures. Craters of more than 100 nm in diameter commonly have melted residue at their bottom. These morphologies are similar to those of submicrometer-sized craters on lunar regolith. We estimated the impactor flux on Itokawa regolith-forming craters, assuming that the craters were accumulated during direct exposure to the space environment for 102 to 104 yr. The range of impactor flux onto Itokawa particles is estimated to be at least one order of magnitude higher than the interplanetary dust flux and comparable to the secondary impact flux on the Moon. This indicates that secondary ejecta impacts are probably the dominant cratering process in the submicrometer range on Itokawa regolith particles, as well as on the lunar surface. We demonstrate that secondary submicrometer craters can be produced anywhere in centimeter- to meter-sized depressions on Itokawa's surface through primary interplanetary dust impacts. If the surface unevenness on centimeter to meter scales is a significant factor determining the abundance of submicrometer secondary cratering, the secondary impact flux could be independent of the overall shapes or sizes of celestial bodies, and the secondary impact flux could have similar values on Itokawa and the Moon.

Community-dwelling persons with stroke in the rural areas of China ( N = 639). Not applicable. Depression (Hamilton Rating Scale for Depression-6), activity and social participation (Chinese version of the World Health Organization's Disability Assessment Schedule 2.0), environmental barriers (Craig Hospital Inventory of Environmental Factors), neurological function (Canadian Neurological Scale). A total of 42% of the variance in depression was explained by the environmental barriers, neurological function, activity, and social participation factors studied. Social participation, services/assistance, and attitudes/support were directly related to depression; their standardized regression coefficients were 0.530, 0.162, and 0.092, respectively ( p ⩽ 0.01). The physical environment, policies, and neurological function indirectly impacted depression. Depression influences social participation in turn, with a standardized regression coefficient of 0.29 ( p ⩽ 0.01). Depression and social participation are inversely related. The physical environment, services/assistance, attitudes/support, and policies all impact post-stroke depression.

Psychosocial and social theories of mood disorders indicate that factors connected with women's gender roles could create a higher risk of depression. The fact that social role is an important factor associated with depressive disorders suggests that not only a biological but also a psychological gender influences the vulnerability to depression. Gender schema theory was applied to investigate a role of femininity in depressive disorders. It was predicted that patients who identify themselves with the traditional feminine gender role will be more depressed than androgynous and undifferentiated patients or individuals with high level of masculinity. Sixty one patients suffering from affective disorder participated in this research. The Polish adaptation of Bem Sex - Role Inventory and Beck Depression Inventory were used to investigate the association between psychological gender and symptoms of depression. The results indicated that there is a significant connection between the type of psychological gender and the level of depression. The highest level of depression was shown by undifferentiated patients, femininity was also found to be associated with a great number of depressive symptoms. These findings also suggest that androgynous individuals and patients with a high level of masculinity tend to be less depressed. Psychological gender is an important factor which interacts to create a higher depression risk in men and women.

Our aim was to study factors associated with long-term non-recovery from major depression. A total of 109 patients with major depression were followed prospectively for 2 years. A diagnosis of major depression based on SCID interviews at follow-up indicated non-recovery. The effect of several established risk factors was assessed. A third (30%) of the patients did not recover. Severity of initial depression were associated with poor outcome according to univariate analysis. Nevertheless, personality disorder and rural area of residence were associated with non-recovery in final multivariate analysis. Major depression in patients with personality disorder should be treated as effectively as possible. Moreover, service planning in rural areas needs attention.

The overall prevalence rate of depression was 32.3%. from binary logistic regression analysis showed that factors as: under pressure (OR = 4.010, 95%CI: 1.672 - 9.617), having had negative life events (OR = 2.050, 95%CI: 1.170 - 3.591) or tight relations with neighbors (OR = 2.537, 95%CI: 1.053 - 6.113), not quite satisfied (OR = 4.247, 95%CI: 1.521 - 11.855) or satisfied (OR = 2.411, 95%CI: 1.111 - 5.233), on his/her own health status etc., might serve as the possible risk factors for depression. In scores related to social support, and the utilization of such support, there were statistically significant differences seen between the groups with depression and the one without. The prevalence of depression among migrant women of reproductive age appeared to be high in some areas on Wuhan. Factors as: under pressure, having had negative life events, tight relations with neighbors, status on satisfaction of one's own health situation as well as related social support, seemed to be the main risk factors for depression in this population.

Background Studies have shown that maternal depression during pregnancy predicts offspring depression in adolescence. Child maltreatment is also a risk factor for depression. Aims To investigate (a) whether there is an association between offspring exposure to maternal depression in pregnancy and depression in early adulthood, and (b) whether offspring child maltreatment mediates this association. Method Prospectively collected data on maternal clinical depression in pregnancy, offspring child maltreatment and offspring adulthood (18–25 years) DSM-IV depression were analysed in 103 mother–offspring dyads of the South London Child Development Study. Results Adult offspring exposed to maternal depression in pregnancy were 3.4 times more likely to have a DSM-IV depressive disorder, and 2.4 times more likely to have experienced child maltreatment, compared with non-exposed offspring. Path analysis revealed that offspring experience of child maltreatment mediated the association between exposure to maternal depression in pregnancy and depression in adulthood. Conclusions Maternal depression in pregnancy is a key vulnerability factor for offspring depression in early adulthood. PMID:26045352

Mold flux plays important roles in the process of continuous casting. In this article, the performance of mold flux for the casting of Cr12MoV steel was investigated by using a mold simulator. The results showed that the slag film formed in the gap between the initial shell and mold hot surface is thin and discontinuous during the casting process with the Flux BM, due to the absorption of chromic oxide inclusions into the liquid slag, while the slag film formed in the case of the optimized Flux NEW casting process is uniform. The main precipitated crystals in Flux BM slag film are cuspidine (Ca4Si2O7F2) and Cr3O4, but only Ca4Si2O7F2 precipitated in the Flux NEW case. Besides, both the responding temperature and heat flux in the case of Flux BM are relatively higher and fluctuate in a larger amplitude. The surface of the shell obtained in the case of the Flux BM experiment is quite uneven, and many severe depressions, cracks, and entrapped slags are observed in the surface due to the lack of lubrication. However, the obtained shell surface in the case of the Flux NEW shows good surface quality due to the addition of B2O3 and the adjustment of basicity, which can compensate for the negative effects of the mold-flux properties caused by the absorption of chromic oxide during the casting process.

Intimate partner violence (IPV), HIV/AIDS, and substance use are epidemics among low-income urban women that have been described together as the "SAVA syndemic" because of their co-occurring nature. This study examines the synergistic or "syndemic" effect of these three health issues on depression among urban women and evaluates social support as a protective factor that might reduce depressive symptoms associated with the Substance Abuse, Violence, and AIDS (SAVA) syndemic. Data from 445 urban women were collected through in-person interviews. All women were over the age of 18, not pregnant, English speaking, and reported having a main partner in the past year. Twenty-five percent had experienced all three factors of the SAVA syndemic (were HIV-positive, had experienced IPV in the past year, and had used cocaine or heroin in their lifetime). HIV-positive status, hard drug use, IPV, and low levels of social support were all individually associated with greater depressive symptoms. When controlling for demographics and other SAVA factors, IPV and hard drug use in the past 30 days remained associated with depressive symptoms, as did low social support. However, social support did not modify the effect of the SAVA factors on depression. Compared to women who experienced no SAVA factors, women who had experienced all three factors were 6.77 times more likely to have depressive symptoms. These findings confirm that IPV is significantly associated with depressive symptoms and that the syndemic impact of IPV, substance use, and HIV could have even more extreme effects on depression outcomes.

Acculturation is a long-term, multi-dimensional process occurring when subjects of different cultures stay in continuous contact. Previous studies have suggested that elevated rates of depression among different migrant groups might be due to patterns of acculturation and migration related risk factors. This paper focused on prevalence rates of depressive disorders and related risk factors among individuals with Turkish migration backgrounds. A population-based sample of 662 individuals with Turkish migration backgrounds were interviewed by bilingual interviewers using a standardised diagnostic interview for DSM-IV-TR and ICD-10 diagnoses (CIDI DIA-X Version 2.8). Associations between 12-month prevalence rates of depressive disorders with potential risk factors were assessed, including gender, age, socioeconomic status, acculturation status and migration status. 12-month prevalence rates of any depressive disorder were 29.0%, 14.4% of major depressive disorder (MDD) and 14.7% of dysthymia. Older age and low socioeconomic status were most consistently related to higher risks of depressive disorders. Acculturation status showed associations with subtypes of depressive disorder. Associations differed between men and women. Symptom severity of MDD was linked to gender, with females being more affected by severe symptoms. The prevalence of depressive disorders is high in individuals with Turkish migration backgrounds, which can be partly explained by older age, low socioeconomic status and acculturation pressures. Only a limited number of risk factors were assessed. Acculturation in particular is a complex process which might not be sufficiently represented by the applied measures. Further risk factors have to be identified in representative samples of this migrant group.

Brain-derived neurotrophic factors are known to be related to the psychopathology of major depressive disorder. However, studies focusing on drug-naïve first-episode patients are still rare. Over a 6-year period, we examined the serum brain-derived neurotrophic factors levels in patients with first-episode drug-naïve major depressive disorder and compared them with sex-matched healthy controls. We also investigated the relationships between serum brain-derived neurotrophic factors levels, suicidal behavior, and Hamilton Depression Rating Scale scores before and after a 4-week antidepressant treatment. The baseline serum brain-derived neurotrophic factors levels of 71 patients were significantly lower than those of the controls (P=.017), and the Hamilton Depression Rating Scale scores in 71 patients did not correlate with brain-derived neurotrophic factor levels. Brain-derived neurotrophic factor levels were significantly lower in 13 suicidal major depressive disorder patients than in 58 nonsuicidal major depressive disorder patients (P=.038). Among 41 followed-up patients, there was no alteration in serum brain-derived neurotrophic factors levels after treatment with antidepressants (P=.126). In receiver operating characteristic curve analysis of using pretreatment brain-derived neurotrophic factors to estimate the response to treatment, the area under the curve was 0.684. The most suitable cut-off point was 6.1 ng/mL (sensitivity=78.6%, specificity = 53.8%). Our data support the serum brain-derived neurotrophic factor levels in patients with drug-naïve first-episode major depressive disorder were lower than those in the healthy controls, and patients with pretreatment brain-derived neurotrophic factors >6.1 ng/mL were more likely to be responders. Although the relationship of our results to the mechanism of drug action and pathophysiology of depression remains unclear, the measure may have potential use as a predictor of response to treatment. In the future, it needs a large sample to prove these results. © The Author 2016. Published by Oxford University Press on behalf of CINP.

Predictors of Depression Stigma in Medical Students: Potential Targets for Prevention and Education.

Suicide rates are higher among U.S. physicians than the general population. Untreated depression is a major risk factor, yet depression stigma presents a barrier to treatment. This study aims to identify early career indications of stigma among physicians-in-training and to inform the design of stigma-reduction programs. A cross-sectional student survey administered at a large, Midwestern medical school in fall 2009 included measures of depression symptoms, attitudes toward mental health, and potential sources of depression stigma. Principal components factor analysis and linear regression were used to examine stigma factors associated with depression in medical students. The response rate was 65.7%, with 14.7% students reporting a previous depression diagnosis. Most students indicated that, if depressed, they would feel embarrassed if classmates knew. Many believed that revealing depression could negatively affect professional advancement. Factor analyses revealed three underlying stigma constructs: personal weakness, public devaluation, and social/professional discrimination. Students associating personal weakness with depression perceived medication as less efficacious and the academic environment as more competitive. Those endorsing public stigma viewed medication and counseling as less efficacious and associated depression with an inability to cope. Race, gender, and diagnosis of past/current depression also related to beliefs about stigma. Depression measures most strongly predicted stigma associated with personal weakness and social/professional discrimination. Recommendations for decreasing stigma among physicians-in-training include consideration of workplace perceptions, depression etiology, treatment efficacy, and personal attributes in the design of stigma reduction programs that could facilitate help-seeking behavior among physicians throughout their career.

This study aimed to detect the prevalence of depressive symptomatology and its expression in a nonclinical Brazilian adolescent student sample. A sample of students from private and public schools (n = 1555, aged 13 to 17 years) answered the Beck Depression Inventory (BDI). We performed factor analysis of the BDI as an indicator of the expression of depressive symptomatology. The following cut-off scores defined nonclinical subgroups: "nondepressed," BDI < 15; "dysphoria," BDI 16 to 20; and "depressed," BDI > 20. We used discriminant analysis to test whether these subgroups could be separated by the depression-specific and nonspecific items. The point prevalence of depression was 7.6%, according to the BDI cut-off of 20. Girls had higher scores than boys in several items. Scores increased with age. Students from public schools had higher scores than did private school students. Factor analysis showed 2 common factors for the total sample and for each sex: the cognitive affective dimension and the somatic nonspecific dimension. In the adolescents showing clinical depression, items related to self-depreciation, sense of failure, guilty feelings, self-dislike, suicidal wishes, and distortion of body image were common components of BDI factors. Discriminant analysis showed that the BDI highly discriminates depressive symptomatology in adolescent students and also measures specific aspects of depression. The BDI is useful as a measure of specific aspects of depression in nonclinical adolescent samples; it was able to detect depression in approximately 7% of the surveyed population. The expression of depressive symptoms in a Brazilian adolescent population is compatible with international studies in this age group. Detecting depressive symptoms in a school population is a critical preventive strategy; to avoid damage to the learning process, it should be followed with further referral to treatment when needed.

Despite the increased risk of depression and conduct problems in children of depressed parents, the mechanism by which parental depression affects their children's behavioral and emotional functioning is not well understood. The present study was undertaken to determine whether parental depression represents a genuine environmental risk factor in children's psychopathology, or whether children's depression/conduct can be explained as a secondary consequence of the genetic liability transmitted from parents to their offspring. Children of Twins (COT) data collected on 2,674 adult female and male twins, their spouses, and 2,940 of their children were used to address whether genetic and/or family environmental factors best account for the association between depression in parents and depression and conduct problems in their children. Data collected on juvenile twins from the Virginia Twin Study of Adolescent Behavioral Development (VTSABD) were also included to estimate child-specific genetic and environmental influences apart from those effects arising from the transmission of the parental depression itself. The fit of alternative Children of Twin models were evaluated using the statistical program Mx. The most compelling model for the association between parental and juvenile depression was a model of direct environmental risk. Both family environmental and genetic factors accounted for the association between parental depression and child conduct disturbance. These findings illustrate how a genetically mediated behavior such as parental depression can have both an environmental and genetic impact on children's behavior. We find developmentally specific genetic factors underlying risk to juvenile and adult depression. A shared genetic liability influences both parental depression and juvenile conduct disturbance, implicating child conduct disturbance (CD) as an early indicator of genetic risk for depression in adulthood. In summary, our analyses demonstrate differences in the impact of parental depression on different forms of child psychopathology, and at various stages of development.

The aim of this paper is to describe the presence of anxious-depressive symptoms and risk factors and discuss the method of intervention used with women in pregnancy and post-partum. The mood of the woman was assessed by the Edinburgh Postnatal Depression Scale (EPDS) and the Beck Depression Inventory (BDI), personality traits with the Vulnerable Personality Style Questionnaire (VPSQ) and social support through the Social Provisions Scale (PPS). 50 women have completed the evaluation. In line with the international literature, the presence of anxiety-depressive symptoms is accompanied by the presence of multiple risk factors, in particular the familiar seems to be a predisposing factor.

Some small studies suggest that maternal postnatal depression is a risk factor for offspring adolescent depression. However, to our knowledge, no large cohort studies have addressed this issue. Furthermore, only 1 small study has examined the association between antenatal depression and later offspring depression. Understanding these associations is important to inform prevention. To investigate the hypothesis that there are independent associations between antenatal and postnatal depression with offspring depression and that the risk pathways are different, such that the risk is moderated by disadvantage (low maternal education) with postnatal depression but not with antenatal depression. Prospective investigation of associations between symptoms of antenatal and postnatal parental depression with offspring depression at age 18 years in a UK community-based birth cohort (Avon Longitudinal Study of Parents and Children) with data from more than 4500 parents and their adolescent offspring. Diagnosis of offspring aged 18 years with major depression using the International Classification of Diseases, 10th Revision. Antenatal depression was an independent risk factor. Offspring were 1.28 times (95% CI, 1.08-1.51; P = .003) more likely to have depression at age 18 years for each standard deviation increase in maternal depression score antenatally, independent of later maternal depression. Postnatal depression was also a risk factor for mothers with low education, with offspring 1.26 times (95% CI, 1.06-1.50; P = .01) more likely to have depression for each standard deviation increase in postnatal depression score. However, for more educated mothers, there was little association (odds ratio, 1.09; 95% CI, 0.88-1.36; P = .42). Analyses found that maternal education moderated the effects of postnatal but not antenatal depression. Paternal depression antenatally was not associated with offspring depression, while postnatally, paternal depression showed a similar pattern to maternal depression. The findings suggest that treating maternal depression antenatally could prevent offspring depression during adulthood and that prioritizing less advantaged mothers postnatally may be most effective.

Anxiety and depression are common in Parkinson disease and both are important determinants of quality of life in patients. Several risk factors are identified but few research have investigated general and Parkinson's disease (PD)-specific factors comprehensively. The aim of this work was to explore PD-specific and -non-specific risk factors for PD with depression or anxiety. A cross-sectional survey was performed in 403 patients with PD. Multivariate logistic analysis was used to investigate the prevalence and risk factors for the depression and anxiety in PD. The data of patients included demographic information, medicine history, disease duration, age at onset (AAO), family history, anti-parkinsonism drug, modified Hoehn and Yahr staging (H-Y) stage, scales of motor and non-motor symptoms and substantia nigra (SN) echogenic areas. 403 PD patients were recruited in the study. Depression and anxiety were present in 11.17% and 25.81% respectively. Marital status, tumor, higher Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) II score, dyskinesia, higher Hamilton Anxiety Rating Scale (HARS) score and lower the Parkinson's disease sleep scale (PDSS) score were associated with depression in PD. female gender, higher rapid eye movement behavior disorder Questionnaire-Hong Kong (RBD-HK) score, higher Hamilton Deprssion Rating Scale (HAMD) score, higher the scale for outcomes in PD for autonomic symptoms (SCOPA-AUT)score and larger SN echogenic areas were associated with anxiety. Neither depression nor anxiety was related to any anti-parkinsonism drugs. The prevalence of depression and anxiety in the current PD patients was 11.17% and 25.81% respectively. Disease of tumor, currently having no partner, severer motor function, dyskinesia, poorer sleep quality and anxiety were risk factors for PD with depression. Female, depression, rapid eye movement behavior disorder (RBD), autonomic dysfunction and larger SN area were risk factors for PD with anxiety.

Background Mothers of infants hospitalized in the neonatal intensive care unit (NICU) are at risk for clinically significant levels of depression and anxiety symptoms; however, the maternal/infant characteristics that predict risk have been difficult to determine. Previous studies have conceptualized depression and anxiety symptoms separately, ignoring their comorbidity. Moreover, risk factors for these symptoms have not been assessed together in one study sample. Objectives The primary aim of this study was to determine whether a diagnostic classification approach or a common-factor model better explained the pattern of symptoms reported by NICU mothers, including depression, generalized anxiety, panic, and trauma. A secondary aim was to assess risk factors of aversive emotional states in NICU mothers based on the supported conceptual model. Method In this cross-sectional study, a nonprobability convenience sample of 200 NICU mothers completed questionnaires assessing maternal demographic and infant health characteristics, as well as maternal depression and anxiety symptoms. Structural equation modeling was used to test a diagnostic classification model, and a common-factor model of aversive emotional states and the risk factors of aversive emotional states in mothers in the NICU. Results Maximum likelihood estimates indicated that examining symptoms of depression and anxiety disorders as separate diagnostic classifications did not fit the data well, whereas examining the common factor of negative emotionality rendered an adequate fit to the data, and identified a history of depression, infant illness, and infant prematurity as significant risk factors. Discussion This study supports a multidimensional view of depression, and should guide both clinical practice and future research with NICU mothers. PMID:25171558

Seeking help from others is an essential behavioural intention for humans to adapt to the social environment. Transgenerational and gender-related mechanisms of how this intention is shaped is an important but unresolved question in adolescent development. This study aimed to comprehensively examine the factors promoting or inhibiting intention to seek help for depression in 10-year-olds, including transgenerational factors, and to investigate the sex differences in the effect of these factors. A cross-sectional study was conducted on a community of 4478 10-year-old children and their parents using self-report questionnaires and face-to-face interviews. The dependent variable was intention of seeking help for depression, which was assessed using a depression case vignette. Independent variables were demographic, psychological, and transgenerational/social factors including depressive symptoms, psychotic-like symptoms, tendency to help classmates, and parents' help-seeking intention. Girls were more likely to seek help than boys. Multivariate logistic regression analysis showed that factors promoting help-seeking intention included the recognition of a need for help, emotional openness, tendency to help classmates, parents' positive intention of seeking help for depression, and the number of people to consult. The inhibiting factors included depressive symptoms, psychotic-like symptoms, and gender norms regarding problem solving. Gender norms inhibited intention of seeking help for depression more strongly in boys than in girls. Parents' and children's help-seeking intention were correlated to each other. Actions should be considered against gender norms presuming that boys should solve their own problems. Further, these actions should target adults as much as adolescents. Copyright © 2018.

The period of the cancer patients undergoing treatment is also the most stressful time for their family caregivers. This study aimed to determine the rates of major depressive disorder and dysthymia; and their associated factors in the caregivers during this time. One hundred and thirty caregiver-patient dyads attending the oncology centre for breast cancer treatment participated in this cross-sectional study. While the data on the patients' socio-demographic and illness characteristics were obtained from their medical record, the caregivers completed three self-report measures: 1) socio-demography and the caregiving factor questionnaire, 2) Multi-dimensional Perceived Social Support (MSPSS) and 3) Depression, Anxiety and Stress Scale (DASS-21). Subsequently, those with "probable depression" identified from the DASS-21 score were interviewed using The Mini-International Neuropsychiatric Interview (MINI) to obtain the diagnoses of depressive disorders. Twenty-three of the 130 caregivers (17.69%) were diagnosed to have depressive disorders, where 12.31% (n=16) had major depressive disorder and 5.38% (n=7) had dysthymic disorder. Factors associated with depression include ethnicity, duration of caregiving, the patients' functional status and the caregivers' education level. Logistic regression analysis showed that the patients' functional status (p<0.05, OR=0.23, CI=0.06-0.86) and the caregivers' education level (p<0.05, CI=9.30, CI=1.82-47.57) were significantly associated with depression in the caregivers attending to breast cancer patients on oncology treatment. A significant proportion of family caregivers were clinically depressed while caring for their loved ones. Depression in this population is a complex interplay between the patients' factors and the caregivers' factors. Copyright © 2014 Elsevier Inc. All rights reserved.

This study aims to recognize and estimate the prevalence of depression and its risk factors among residents of assisted living facilities (ALs) in Jordan. Depression is commonly experienced by residents of ALs. The condition is, however, often misunderstood as a part of normal aging and may be overlooked by health care professionals. Little is known about the extent of depression and its risk factors among AL residents in Jordan. A national representative sample of 221 residents selected from all AL units across Jordan was recruited to the study. Data on expected risk factors for depression were collected, including sociodemographics; smoking status; number of roommates; number of family members; assessments for cognitive functioning, for lower limb functioning, for hand, shoulder, and arm impairments; and oral health status. Levels of depression among the sample respondents were also assessed. The study found that around 60% of the participants reported depressive manifestations, with 48.0% of AL residents exhibiting impaired cognitive functions, one-third (33.2%) having >50% upper limb disability, two-thirds (63.2%) being at moderate risk of falls, and 69.7% having fair to poor oral health status. Being female, and having a higher level of education, disability of the upper limbs, and impairment of cognitive functions were found to be independent risk factors for depression in participants. Depression is relatively common among residents of AL units in Jordan. Health care professionals, nurses, physiotherapists, and dentists working in these facilities need to work cooperatively to identify the manifestations of depression in residents and collaboratively implement the best practice in the treatment of depression and circumvent its long-term impacts on the health of residents.

Plasma cortisol and oxytocin levels predict help-seeking intentions for depressive symptoms.

PubMed

Depressed individuals often refuse or withdraw from help, a phenomenon termed help-negation, which is a risk factor for poor outcomes. Most previous research has investigated psychosocial factors including stigma as causes of low help-seeking intentions for depression, however these do not adequately explain the problem. We hypothesised that because help-negation worsens with symptom severity, it might be linked to important biological changes associated with depression itself. We investigated the relative contributions of cortisol, a stress hormone linked to depression, and oxytocin, a hormone which mediates social behaviours, alongside psychosocial factors, to help-seeking intentions among depressed and non-depressed individuals. Morning plasma cortisol and oxytocin levels, psychopathology, suicidal ideation, help-seeking intentions from informal sources including family and friends, and formal sources including health professionals, and perceived social support were quantified in 63 adults meeting DSM-5 criteria for major depressive disorder (MDD) who were not receiving any treatment, and 60 healthy controls. Between-group analyses of variance, correlations, and hierarchical multiple regressions were employed. Help-seeking intentions were lower in depressed than healthy participants, negatively correlated to cortisol and positively correlated to oxytocin. Cortisol negatively, and oxytocin positively, predicted help-seeking intentions from informal but not formal sources, after controlling for psychopathology and psychosocial factors. Neuroendocrine changes associated with depression may contribute to low help-seeking from friends and family, which may have implications for interpersonal support and outcomes. Research and clinical approaches which incorporate biological as well as psychosocial factors may allow for more targeted and effective early interventions to address lack of help-seeking and depression progression.

Depression is a well known health problem worldwide. Prevalence of depressive disorders varies in different societies. to determine the prevalence of depressive disorders and some associated factors in Rasht City (Northern part of Iran). 4020 subjects were selected among 394925 residents of Rasht aged between 18-70 during 2003 - 2004. In the first phase, subjects were screened by Beck's Depression Inventory. In the second phase, those who scored more than 15 were assessed through semi-structured psychiatric interview (DSMIV-TR). Socio-demographic characteristics including age, gender, marital status, educational level, and socio-economic class were recorded as well. 9.5% of samples (63% female and 37% male) were diagnosed by depressive disorders. The prevalence of minor depressive disorder, dysthymia and major depressive disorder was 5%, 2/5%, and 1% respectively. Socio-economic class was significantly associated with both depressive symptoms based on BDI score (p < 0.001) and depressive disorders based on clinical interview (p < 0.001). Comparing to other studies, this study revealed that prevalence of dysthymic and minor depressive disorder were more than major depressive disorder, and low socio-economic class was the most significant risk factor associated with depression. Regarding our study limitations, researchers and policy makers should not consider our findings as conclusive results. Findings of this study could be applied by researchers using analytical methodology to assess relationship between depressive disorders and associated factors.

Previous studies found a relationship between geriatric depression and social deprivation. However, most studies did not include environmental factors in the statistical models, introducing a bias to estimate geriatric depression risk because the urban environment was found to have significant associations with mental health. We developed a cross-sectional study with a binomial logistic regression to examine the geriatric depression risk of a high-density city based on five social vulnerability factors and four environmental measures. We constructed a socio-environmental vulnerability index by including the significant variables to map the geriatric depression risk in Hong Kong, a high-density city characterized by compact urban environment and high-rise buildings. Crude and adjusted odds ratios (ORs) of the variables were significantly different, indicating that both social and environmental variables should be included as confounding factors. For the comprehensive model controlled by all confounding factors, older adults who were of lower education had the highest geriatric depression risks (OR: 1.60 (1.21, 2.12)). Higher percentage of residential area and greater variation in building height within the neighborhood also contributed to geriatric depression risk in Hong Kong, while average building height had negative association with geriatric depression risk. In addition, the socio-environmental vulnerability index showed that higher scores were associated with higher geriatric depression risk at neighborhood scale. The results of mapping and cross-section model suggested that geriatric depression risk was associated with a compact living environment with low socio-economic conditions in historical urban areas in Hong Kong. In conclusion, our study found a significant difference in geriatric depression risk between unadjusted and adjusted models, suggesting the importance of including environmental factors in estimating geriatric depression risk. We also developed a framework to map geriatric depression risk across a city, which can be used for identifying neighborhoods with higher risk for public health surveillance and sustainable urban planning.

Health status and lifestyle factors as predictors of depression in middle-aged and elderly Japanese adults: a seven-year follow-up of the Komo-Ise cohort study

PubMed Central

2011-01-01

Background Depression is a common mental disorder. Several studies suggest that lifestyle and health status are associated with depression. However, only a few large-scale longitudinal studies have been conducted on this topic. Methods The subjects were middle-aged and elderly Japanese adults between the ages of 40 and 69 years. A total of 9,650 respondents completed questionnaires for the baseline survey and participated in the second wave of the survey, which was conducted 7 years later. We excluded those who complained of depressive symptoms in the baseline survey and analyzed data for the remaining 9,201 individuals. In the second-wave survey, the DSM-12D was used to determine depression. We examined the risks associated with health status and lifestyle factors in the baseline survey using a logistic regression model. Results An age-adjusted analysis showed an increased risk of depression in those who had poor perceived health and chronic diseases in both sexes. In men, those who were physically inactive also had an increased risk of depression. In women, the analysis also showed an increased risk of depression those with a BMI of 25 or more, in those sleeping 9 hours a day or more and who were current smokers. A multivariate analysis showed that increased risks of depression still existed in men who had chronic diseases and who were physically inactive, and in women who had poor perceived health and who had a BMI of 25 or more. Conclusions These results suggest that lifestyle and health status are risk factors for depression. Having a chronic disease and physical inactivity were distinctive risk factors for depression in men. On the other hand, poor perceived health and a BMI of 25 or more were distinctive risk factors for depression in women. Preventive measures for depression must therefore take gender into account.

Use of Thermal Data to Estimate Infiltration in Pagany Wash Associated with the winter of 1997-1998 El Nino Precipitation, Yucca Mountain, Nevada

DOE Office of Scientific and Technical Information (OSTI.GOV)

G.D. LeCain; N. lu; M. Kurzmack

Temperature and air-pressure monitoring in a vertical borehole located in Pagany Wash, a normally dry stream-carved channel northeast of Yucca Mountain, Nevada, indicated that the annual temperature wave was measurable to a depth of 11.1 m. Temperature depressions were measured at depths of 3.1, 6.1, 9.2, and 11.1 m below ground surface. The temperature depressions were interpreted to be the result of infiltration associated with the 1997-1998 El Nino precipitation. A pressure differential, of approximately 2 kiloPascals, between stations located 11.1 and 24.5 m below ground surface was interpreted to be the result of compressed air ahead of the wettingmore » front. The pressure differences between stations indicated that the wetting front migrated deeper than 35.2 m and that the Yucca Mountain Tuff retarded the downward movement of the wetting front. An analytical method indicated that the infiltration flux through the Pagany Wash alluvium due to the 1997-1998 El Nino precipitation was approximately 940 mm. A one-dimensional numerical model indicated that the infiltration flux was approximately 1000 mm. Sensitivity analysis indicated that the potential temperature decrease due to conduction was minimal and that cooler surface temperatures could not account for the measured subsurface temperature depressions.« less

Unipolar and bipolar depression identified in the postpartum period have a heterogeneous etiology. The objectives of this study are to examine the risk factors that distinguish the timing of onset for unipolar and bipolar depression and the associations between depression onset by diagnosis, and general and atypical depressive symptoms. Symptoms of depression were assessed at 4- to 6-weeks postpartum by the Structured Interview Guide for the Hamilton Depression Rating Scale-Atypical Depression Symptoms in an obstetrical sample of 727 women. Data were analyzed using ANOVA, Chi-square, and linear regression. Mothers with postpartum onset of depression were more likely to be older, Caucasian, educated, married/cohabitating, have one or no previous child, and have private insurance in contrast to mothers with pre-pregnancy and prenatal onset of depression. Mothers with bipolar depression were more likely to have a pre-pregnancy onset. Three general and two atypical depressive symptoms distinguished pre-pregnancy, during pregnancy, and postpartum depression onset, and the presence of agitation distinguished between unipolar and bipolar depression. The sample was urban, which may not be generalizable to other populations. The study was cross-sectional, which excludes potential late onset of depression (after 4-6 weeks) in the first postpartum year. A collective set of factors predicted the onset of depression identified in the postpartum for mothers distinguished by episodes of unipolar versus bipolar depression, which can inform clinical interventions. Future research on the onset of major depressive episodes could inform prophylactic and early psychiatric interventions. Copyright © 2016 Elsevier B.V. All rights reserved.

Microelectronic engineers are considered valuable human capital contributing significantly toward economic development, but they may encounter stressful work conditions in the context of a globalized industry. The study aims at identifying risk factors of depressive disorders primarily based on job stress models, the Demand-Control-Support and Effort-Reward Imbalance models, and at evaluating whether depressive disorders impair work performance in microelectronics engineers in Taiwan. The case-control study was conducted among 678 microelectronics engineers, 452 controls and 226 cases with depressive disorders which were defined by a score 17 or more on the Beck Depression Inventory and a psychiatrist's diagnosis. The self-administered questionnaires included the Job Content Questionnaire, Effort-Reward Imbalance Questionnaire, demography, psychosocial factors, health behaviors and work performance. Hierarchical logistic regression was applied to identify risk factors of depressive disorders. Multivariate linear regressions were used to determine factors affecting work performance. By hierarchical logistic regression, risk factors of depressive disorders are high demands, low work social support, high effort/reward ratio and low frequency of physical exercise. Combining the two job stress models may have better predictive power for depressive disorders than adopting either model alone. Three multivariate linear regressions provide similar results indicating that depressive disorders are associated with impaired work performance in terms of absence, role limitation and social functioning limitation. The results may provide insight into the applicability of job stress models in a globalized high-tech industry considerably focused in non-Western countries, and the design of workplace preventive strategies for depressive disorders in Asian electronics engineering population.

Psychosocial and inflammatory factors have been associated with fatigue in breast cancer survivors. Nevertheless, the relative contribution and/or interaction of these factors with cancer-related fatigue have not been well documented. This cross-sectional study enrolled 111 stage 0-III breast cancer patients treated with breast surgery followed by whole breast radiotherapy. Fatigue was measured by the total score of the Multidimensional Fatigue Inventory-20. Potential risk factors included inflammatory markers (plasma cytokines and their receptors and C-reactive protein; CRP), depressive symptoms (as assessed by the Inventory of Depressive Symptomatology-Self Reported), sleep (as assessed by the Pittsburgh Sleep Quality Index) and perceived stress (as assessed by the Perceived Stress Scale) as well as age, race, marital status, smoking history, menopause status, endocrine treatment, chemotherapy and cancer stage. Linear regression modeling was employed to examine risk factors of fatigue. Only risk factors with a significance level <0.10 were included in the initial regression model. A post-hoc mediation model using PROCESS SPSS was conducted to examine the association among depressive symptoms, sleep problems, stress, inflammation and fatigue. At 1 year post-radiotherapy, depressive symptoms (p<0.0001) and inflammatory markers (CRP: p = 0.015; interleukin-1 receptor antagonist: p = 0.014; soluble tumor necrosis factor receptor-2: p = 0.009 in separate models) were independent risk factors of fatigue. Mediation analysis showed that depressive symptoms also mediated the associations of fatigue with sleep and stress. Depressive symptoms and inflammation were independent risk factors for cancer-related fatigue at 1 year post-radiotherapy, and thus represent independent treatment targets for this debilitating symptom.

Comorbidity of anxiety and depression predicts impaired treatment outcomes, poor quality of life and increased suicide risk. No study has reported on a combined measure of anxiety-depression in boys with an Autism Spectrum Disorder. To explore the prevalence, underlying factor structure and relationships between anxiety-depression, physiological stress and symptoms of Autism Spectrum Disorder (ASD). 150 boys (aged 6-18 years; IQ M=94.9, range=73-132) with an ASD plus their parents (135 mothers, 15 fathers) completed scales about the boys' anxiety and depression, and the boys provided samples of their saliva in the morning and afternoon. Parents also completed the ASD Behaviour Checklist about the boys' ASD symptoms. The two sources of ratings were not significantly different for prevalence of anxiety-depression but the factor structures varied between the parents' and boys' responses, with a four-factor solution for the boys' ratings and a three-factor solution for the parents' ratings. There were also differences in the correlations between cortisol and anxiety-depression and between ASD symptoms and anxiety depression across the boys' and parents' data. Assessment of anxiety and depression comorbidity from parents and from children with an ASD themselves could provide a valuable adjunct datum when diagnosing ASD. Copyright © 2015 Elsevier Ltd.

Although depression is common amongst adolescents attending general practice, little is known about factors which influence consultation. This study aims to identify factors that contribute to GP attendance in adolescents with high levels of mood symptoms. Case-control study of 13 to 17-year-olds attending (cases, N = 156) and not attending (controls, N = 120) an urban general practice during a 6-month period; questionnaires on depressive symptoms (Mood and Feelings Questionnaire), physical symptoms (Child Somatisation Inventory), socio-demographic data and attitudes were completed. Attenders had significantly more depressive and physical symptoms. In the comparison between 63 attenders and 34 non-attenders with a high level of depressive symptoms, attendance was significantly linked to lower socio-economic status, non-White ethnicity, non-intact families, and not believing that doctors are only interested in physical symptoms. On logistic regression analysis, attendance in males with depressive symptoms was predicted by more physical and less marked depressive symptoms; in females by non-White ethnicity and not believing doctors are only interested in physical symptoms. Both socio-demographic factors and adolescent attitudes influence general practitioner attendance in adolescents with high levels of depressive symptoms. These findings may help inform interventions to facilitate help seeking in primary care for young people with high levels of depressive symptoms.

Elevated Appraisals of the Negative Impact of Naturally Occurring Life Events: A Risk Factor for Depressive and Anxiety Disorders

Espejo, Emmanuel P.; Hammen, Constance; Brennan, Patricia A.

2012-01-01

The tendency to appraise naturally occurring life events (LEs) as having high negative impact may be a predisposing factor for the development of depression and anxiety disorders. In the current study, appraisals of the negative impact of recent LEs were examined in relationship to depressive and anxiety disorders in a sample of 653 adolescents who were administered diagnostic and life stress interviews at ages 15 and 20. Participants’ appraisals of the negative impact of LEs reported at age 15 were statistically adjusted using investigator-based ratings to control for objective differences across LEs. Higher appraisals of the negative impact of LEs were associated with both past and current depressive and anxiety disorders at age 15 and predicted subsequent first onsets of depressive and anxiety disorders occurring between ages 15 and 20. In addition, appraisals of the negative impact of LEs were particularly elevated among those experiencing both a depressive and anxiety disorder over the course of the study. The findings suggest that systematically elevated appraisals of the negative impact of LEs is a predisposing factor for depression and anxiety disorders and may represent a specific risk factor for co-morbid depression and anxiety in mid-adolescence and early adulthood.

Introduction. Despite the fact that maternal perinatal mental health problems have been extensively studied and addressed to be a significant health problem, the literature on paternal perinatal mental health problems is relatively scarce. The present study aims at determining the prevalence of paternal perinatal depression and identifying the risk factors and the relationship between antenatal and postpartum depression. Methodology. 622 expectant fathers were recruited from regional maternal clinics. The expectant fathers were assessed using standardized and validated psychological instruments on 3 time points including early pregnancy, late pregnancy, and six weeks postpartum. Results. Results showed that a significant proportion of expectant fathers manifested depressive symptoms during the perinatal period. Paternal antenatal depression could significantly predict higher level of paternal postpartum depression. Psychosocial risk factors were consistently associated with paternal depression in different time points. Conclusions. The present study points to the need for greater research and clinical attention to paternal depression given that it is a highly prevalent problem and could be detrimental to their spouse and children development. The present findings contribute to theoretical basis of the prevalence and risk factors of paternal perinatal depression and have implications of the design of effective identification, prevention, and interventions of these clinical problems.

Objective To examine the association between physical frailty and neurocognitive performance in late-life depression (LLD). Methods Cross-sectional design using baseline data from a treatment study of late-life depression. Individuals aged 60 and older diagnosed with Major Depressive Disorder at time of assessment (N = 173). All participants received clinical assessment of depression and completed neuropsychological testing during a depressive episode. Physical frailty was assessed using an adaptation of the FRAIL scale. Neuropsychological domains were derived from a factor analysis that yielded three factors: 1) Speeded Executive and Fluency, Episodic Memory, and Working Memory. Associations were examined with bivariate tests and multivariate models. Results Depressed individuals with a FRAIL score >1 had worse performance than nonfrail depressed across all three factors; however, Speeded Executive and Fluency was the only factor that remained significant after controlling for depression symptom severity and demographic characteristics. Conclusions Although physical frailty is associated with broad neurocognitive deficits in LLD, it is most robustly associated with deficits in speeded executive functions and verbal fluency. Causal inferences are limited by the cross-sectional design, and future research would benefit from a comparison group of nondepressed older adults with similar levels of frailty. Research is needed to understand the mechanisms underlying associations among depression symptoms, physical frailty, and executive dysfunction, and how they are related to the cognitive and symptomatic course of LLD.

On Multiple Hall-Like Electron Currents and Tripolar Guide Magnetic Field Perturbations During Kelvin-Helmholtz Waves

Two magnetopause current sheet crossings with tripolar guide magnetic field signatures were observed by multiple Magnetosphere Multiscale (MMS) spacecraft during Kelvin-Helmholtz wave activity. The two out-of-plane magnetic field depressions of the tripolar guide magnetic field are largely supported by the observed in-plane electron currents, which are reminiscent of two clockwise Hall current loop systems. A comparison with a three-dimensional kinetic simulation of Kelvin-Helmholtz waves and vortex-induced reconnection suggests that MMS likely encountered the two Hall magnetic field depressions on either side of a magnetic reconnection X-line. Moreover, MMS observed an out-of-plane current reversal and a corresponding in-plane magnetic field rotation at the center of one of the current sheets, suggesting the presence of two adjacent flux ropes. The region inside one of the ion-scale flux ropes was characterized by an observed decrease of the total magnetic field, a strong axial current, and significant enhancements of electron density and parallel electron temperature. The flux rope boundary was characterized by currents opposite this axial current, strong in-plane and converging electric fields, parallel electric fields, and weak electron-frame Joule dissipation. These return current region observations may reflect a need to support the axial current rather than representing local reconnection signatures in the absence of any exhausts.

Depression in old age is an important public health problem causing considerable morbidity and disability worldwide. There is a dearth of community studies from India investigating geriatric depression and its associated risk factors. This study aimed to establish the nature, prevalence and factors associated with geriatric depression in a rural south Indian community. We recruited 1000 participants aged over 65 years from Kaniyambadi block, Vellore, India. We assessed their socio-demographic profile, psychiatric morbidity, cognitive functioning, anthropometrics and disability status using the following structured assessment tools: Geriatric Mental State, Community Screening Instrument for Dementia, Modified CERAD 10 word list learning task, History and Aetiology Schedule Dementia Diagnosis and Subtype, WHO Disability Assessment Scale II, and Neuropsychiatric Inventory. We adopted a case control framework to study the factors associated with geriatric depression. Prevalence of geriatric depression (ICD-10) within the previous one month was 12.7% (95% CI 10.64-14.76%). Low income (OR 1.78; 95% CI 1.08-2.91), experiencing hunger (OR 2.58; 95% CI 1.56-4.26), history of cardiac illnesses (OR 4.75; 95% CI 1.96-11.52), transient ischemic attack (OR 2.43; 95% CI 1.17-5.05), past head injury (OR 2.70; 95% CI 1.36-5.36) and diabetes (OR 2.33; 95% CI 1.15-4.72) increased the risk for geriatric depression after adjusting for other determinants using conditional logistic regression. Having more confidants (OR 0.13; 95% CI 0.06-0.26) was the significant protective factor. Age, female gender, cognitive impairment and disability status were not significantly associated with geriatric depression. DSM-IV diagnosis of major depression was significantly correlated with experiencing hunger, diabetes, transient ischemic attack, past head injury, more disability and less nourishment; having more friends was protective. Geriatric depression is prevalent in rural south India. Poverty and physical ill health are risk factors for depression among elderly while good social support is protective.

According to the American Cancer Society, 25% of cancer survivors in the United States develop depression. The objective of this study is to assess factors associated with self-reported history of depression diagnosis among cancer survivors aged ≥18 years in the United States. Data were analyzed from the 2014 Behavioral Risk Factor Surveillance System (N = 6079). The Behavioral Risk Factor Surveillance System collects data about US residents regarding their health-related risk behaviors and events, chronic health conditions, and use of preventive services. Respondents were considered to have a history of depression diagnosis if they answered yes to the question "Has a doctor or other health care provider EVER told you that you have a depressive disorder, including depression, major depression, dysthymia, or minor depression?" Bivariate and multivariable logistic regression analyses were conducted to assess factors associated with depression in cancer survivors. Analyses were conducted using SAS 9.4. After adjusting for demographic and socioeconomic factors, females (AOR: 1.70; 95% CI, 1.50-1.97); those with an annual household income of $24 999 or less (AOR: 2.48; 95% CI, 1.95-3.16); $25 000 to $49 999 (AOR: 1.62; 95% CI, 1.31-2.02), and $50 000 to $74 999 (AOR: 1.35; 95% CI, 1.10-1.71); those who were not married (AOR = 1.37; 95% CI, 1.17-1.60); and those who perceived their health as poor (AOR = 2.33; 95% CI, 2.01-2.70), were significantly more likely to report a diagnosis of depression. The results indicate that gender, income, marital status, and perceived health status were associated with self-reported depression among cancer survivors aged ≥18 years in the United States.

While maternal postpartum depression is a well-known phenomenon, paternal postnatal depression has been less studied. It is known that paternal postnatal depression impacts on children's and families' development, affects marital satisfaction and affects the economic health of industrialized countries. The aim of this study was to identify the psychosocial factors associated with paternal postnatal depression. A descriptive-correlational study was conducted with a sample of fathers of infants (average age: 11 months) who were breastfed exclusively or predominantly for at least 6 months, comparing psychosocial factors in fathers with (n: 17, 8.2%) and without a positive score for depression on the EPDS scale (n: 188). Psychosocial factors were assessed through questionnaires. Depression in fathers of breastfed infants is associated with the experience of perinatal loss in a previous pregnancy, parenting distress, infant temperament (difficult child), dysfunctional interactions with the child, decreased marital adjustment and perceived low parenting efficacy. Multivariate analysis suggests an independent effect of psychosocial factors such as parenting distress, quality of the marital relationship and perceived parenting efficacy on paternal depression. The sample focused on fathers of breastfed infant, since breastfeeding has become the feeding norm, and this should be taken into account when considering the generalization of findings. These findings emphasize the need to consider a set of psychosocial factors when examining fathers' mental health in the first year of a child's birth. Health professionals can enhance parenting efficacy and alleviate parenting distress by supporting fathers' unique experiences and addressing their needs. Copyright © 2013 Elsevier B.V.

Mental health problems among women of reproductive age group contribute to 7% of Global Burden of Diseases of women of all ages. Purpose of this study was to determine the prevalence and correlates of antenatal depression among pregnant women in Anuradhapura, Sri Lanka, and to explore the factor structure of EPDS. Pregnant women with gestational age of 24-36 weeks and residing in Anuradhapura district, Sri Lanka were recruited to the study using a two stage cluster sampling procedure. Sinhalese version of Edinburgh Post Partum Depression Scale (EPDS) and an interviewer administered questionnaire was use to collect data. A cut off value of 9 was used for the Sinhalese version of EPDS. A total of 376 pregnant women were studied. Median EPDS score among pregnant women was 5 (IQR 2-8). Prevalence of antenatal depression in this study sample was 16.2% (n = 61). Thought of self harming (item number 10) was reported by 26 pregnant women (6.9%). None of the socio-demographic factors were associated with depression in this study sample. Having heart burn was significantly associated with depressive symptoms (p = 0.041). Sri Lankan version of EPDS showed a two factor solution. Anxiety was not emerged as a separate factor in this analysis. Prevalence of antenatal depression in Anuradhapura, Sri Lanka was relatively low. Anxiety was not emerged as a separate factor in the Sinhalese version of the EPDS.

In South Korea, the number of workers suffering from mental illnesses, such as depression, has rapidly increased. There is growing concern about depressive symptoms being associated with both working conditions and psychosocial environmental factors. To investigate potential psychosocial environmental moderators in the relationship between working conditions and occupational depressive symptoms among wage workers. Data were obtained from the wage worker respondents (n = 4,095) of the Korean National Health and Nutrition Examination Survey of 2009. First, chi-square tests confirmed the differences in working conditions and psychosocial characteristics between depressive and non-depressive groups. Second, multivariate logistic regression analysis was performed to examine the moderating effects of the psychosocial environmental factors between working conditions and depressive symptoms. After adjusting for potential covariates, the likelihood of depressive symptomatology was high among respondents who had dangerous jobs and flexible work hours compared to those who had standard jobs and fixed daytime work hours (OR = 1.66 and 1.59, respectively). Regarding psychosocial factors, respondents with high job demands, low job control, and low social support were more likely to have depressive symptoms (OR = 1.26, 1.58 and 1.61, respectively). There is a need to develop non-occupational intervention programs, which provide workers with training about workplace depression and improve social support, and the programs should provide time for employees to have active communication. Additionally, companies should provide employees with support to access mental healthcare thereby decreasing the occurrence of workplace depression.

This study utilized Malay version Geriatric Depression Scale 14 (M-GDS 14) to screen for elderly depression among Malaysian population. It also looked into associated risk factors for elderly depression using sociodemographic, family dynamics, and medically related questionnaires. Out of 244 subjects, 34 or 13.9% were found to have depression. Three variables were found to be significantly associated with depression. Elderly patient with any illness that limits the patient's activity or mobility has more risk of developing depression (OR 2.68 CI 1.15 - 6.24). Elderly patients who were satisfied with their personal incomes (OR 0.29 CI 0.10 - 0.85), and who had children or son/daughter-in-law to take care of them when they are sick (OR 0.10 CI 0.01 - 0.83) have a lower chance of having depression. Screening the elderly for depression, would help in diagnosing the elderly depression better and offer them the treatment needed.

HIV/AIDS is one of the most devastating illnesses that humans have ever faced. Depression in HIV/AIDS patients is very common but the factors affecting it are not well studied. HIV/AIDS though such a big public health problem worldwide, not enough data is available regarding association of HIV and Depression. Therefore this study was undertaken to evaluate the association between HIV/AIDS and depression in an Indian setting. The study was conducted in Guru Teg Bahadur Hospital and University College of Medical Sciences, Delhi. One hundred sixty patients were interviewed using a questionnaire containing factors that affect depression. CES-D (Center for Epidemiologic Studies - Depression) scale was used to measure depression. The data collected was analyzed using SPSS software. The prevalence of depression in patients with HIV under ART was 58.75%. The prevalence of depression increased with the severity of symptoms. The unemployed, uneducated, unmarried, belonging to joint families, having no or low family income, migrants, having indifferent or poor relationship with spouse, poor social support and had visited commercial sex workers had a greater prevalence of depression. The rate of depression in patients with HIV/AIDS is very high. Detecting depression early and treating it goes a long way in improving the compliance to treatment as well as quality of life.

Autistic personality traits (APT) and schizotypal personality traits (SPT) are associated with depression. However, mediating factors within these relationships have not yet been explored. Thus, the focus of the current study was to examine the effects of childhood neglect on the relationship between APT/SPT and depression. This cross-sectional study was conducted on first-year students (N = 2469) at Hunan University of Chinese Medicine and Hengyang Normal College (Changsha, China). Participants completed surveys on APT, SPT, childhood neglect, abuse and depression. Through correlational analyses, APT and SPT traits were positively correlated with childhood neglect and depression (p < 0.05). In a hierarchical regression analysis, among types of childhood maltreatment, emotional neglect (β = 0.112, p < 0.001) and physical neglect (β = 0.105, p < 0.001) were the strongest predictors of depression. Childhood neglect did not account for the relationships between APT/SPT and depression. Further analysis found that childhood neglect mediated the relationship between SPT and depression but not APT and depression. Among types of childhood maltreatment, neglect was the strongest predicting factor for depression. Neglect did not account for the relationship between APT/SPT and depression but was a strong mediating factor between SPT and depression.

Late-life depression is an important public health problem because of its devastating consequences. The study aims to investigate the prevalence and associated factors of self-reported symptom-based depression in a national sample of older South Africans who participated in the Study of Global Ageing and Adult Health (SAGE wave 1) in 2008. We conducted a national population-based cross-sectional study with a probability sample of 3,840 individuals aged 50 years or above in South Africa in 2008. The questionnaire included socio-demographic characteristics, health variables, anthropometric and blood pressure measurements as well as questions on depression symptoms in the past 12 months. Multivariable regression analysis was performed to assess the association of socio-demographic factors, health variables, and depression. The overall prevalence of symptom-based depression in the past 12 months was 4.0%. In multivariable analysis, functional disability, lack of quality of life, and chronic conditions (angina, asthma, arthritis, and nocturnal sleep problems) were associated with self-reported depression symptoms in the past 12 months. Self-reported depression in older South Africans seems to be a public health problem calling for appropriate interventions to reduce occurrence. Factors identified to be associated with depression, including functional disability, lack of quality of life, and chronic conditions (angina, asthma, arthritis, and nocturnal sleep problems), can be used to guide interventions. The identified protective and risk factors can help in formulating public health care policies to improve quality of life among older adults.

Aims and objectives To assess the depression status of type 2 diabetic retinopathy patients in Nantong China and to identify factors associated with depression. Methods Two hundred and ninety-four patients with type 2 diabetic retinopathy were recruited from the Affiliated Hospital of Nantong University. The severity of DR was measured in the worse eye. Depressive symptoms were assessed with the Center for Epidemiologic Studies Depression Scale (CES-D); the quality of life was measured with the Medical Outcomes Study Short Form 36 (SF-36). The logistic regression analyses were used to identify the independent factors of depression. Results The mean age of the study subjects was 57.77 years (SD: 9.64). Approximately 35.7% of subjects reported depressive symptoms (n = 105).Multiple logistic regression analyses showed that female gender (p = 0.014), low monthly income (p = 0.01), poor vision in the better eye (P = 0.002), laser treatment history (p = 0.01) were significant risk factors for depression. The quality of life of individuals with CES-D score<16 was significantly better compared with individuals with CES-D score≥16. Conclusion The reported depressive symptoms among type 2 diabetic retinopathy population is higher in Nantong China. Gender, salary, vision acuity and treatment history were important risk factors linked to this disorder in the Chinese type 2 diabetic retinopathy population from Nantong. More attention by medical care personnel needs to be paid to the psychological health of this population. PMID:26151365

Limited research has been conducted in the United Arab Emirates in relation to postpartum depression. The purpose of this study was to investigate the risk and protective factors of postpartum depression in women in Sharjah, United Arab Emirates. We carried out a prospective study in which we followed women from the second trimester of pregnancy until 4 months postpartum. Data were collected during the second and third trimesters and then at 2- and 4- months postpartum. The risk/protective factors that were investigated included: depression and anxiety during pregnancy, stressful life events, breastfeeding, employment status following delivery, religiosity, and socio-demographic variables. The Edinburgh Postnatal Depression Scale (screening) and the Mini International Neuropsychiatric Inventory (diagnostic) were used as outcome variables. Using the Mini International Neuropsychiatric Inventory (diagnostic), 10% of the 137 participants in the study were diagnosed with postpartum depression. The following variables were found to be predictive of postpartum depression: depression during pregnancy in both the second and third trimesters: number of children, religion, and use of formula for feeding. Several factors were of borderline significance including educational level of mother, lack of breastfeeding, personal stressful life events, and employment status following delivery. These risk factors are important as they indicate potential areas for early identification. Screening of pregnant women during pregnancy and in the postpartum phase would be important. This study forms the foundation for further research and development related to prevention and intervention for postpartum depression in this Arab context.

Background This study explores factors associated with depression in Alzheimer's disease (AD) compared with mild cognitive impairment (MCI) and other dementia disorders. Method In a prospective study we included 195 patients: 31 with MCI, 112 with AD and 52 with other dementias. Results According to the ICD-10 and the DSM-IV criteria, 88 (44.1%) and 59 (30.3%), respectively, had a depressive disorder. An adjusted multiple regression analysis showed that previous depression (p < 0.05) was significantly associated with depression in AD patients. Severity of dementia (p < 0.05) was significantly associated with a depressive disorder in a group of patients with frontotemporal dementia, vascular dementia, or dementia due to Lewy Body disease or Parkinson's disease. Conclusion We found different factors associated with a depressive disorder in AD compared to those found for other dementia disorders. PMID:22479262

A number of studies have demonstrated that symptoms of prolonged grief disorder (PGD) represent a symptom cluster distinct from bereavement-related depression, anxiety, and posttraumatic stress disorder (PTSD). The aim of the present study was to confirm and extend these findings using the most recent criteria defining PGD. The authors interviewed a total of 400 orphaned or widowed survivors of the Rwandan genocide. The syndromes were strongly linked to each other with a high comorbidity. Principal axis factoring resulted in the emergence of 4 different factors. The symptoms of depression, along with the cognitive, emotional, and behavioral symptoms of PGD, loaded on the first factor, symptoms of anxiety on the second factor, symptoms of PTSD on the third factor, and the separation distress symptoms of PGD on the fourth factor. This indicates that the concept of PGD includes symptoms that are conceptually related to depression. However, the symptom cluster of separation distress presents a grief-specific dimension that may surface unrelated to depressive symptoms.

In 1982-1983 a random sample of 1486 people aged 65 years and above was generated from general practitioner lists; 1070 were interviewed in the community using the Geriatric Mental State and a Social History questionnaire. The cohort was followed up by interview 3 years later. At year 3 the diagnostic computer program AGECAT diagnosed 44 incident cases of depression. Information from the depressed group's initial and further interviews was compared with a control group (which excluded cases of affective or organic mental illness). Univariate analysis yielded three factors that were significantly associated with the development of depression 3 years later: a lack of satisfaction with life; feelings of loneliness; and smoking. Multivariate analysis confirmed their independent effects and revealed 2 further factors attaining significance: female gender and a trigger factor, bereavement of a close figure within 6 months of the third-year diagnosis. Some other factors traditionally associated with depression, such as poor housing, marital status and living alone, failed to attain significance as risk factors.

In response to high levels of comorbidity and symptom overlap between posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and other disorders, much attention has been devoted to the role of specific and nonspecific symptoms among the disorders. The present study investigated the overlapping symptoms of PTSD and MDD in treatment-seeking veterans. Exploratory factor analyses were used to identify latent factors of both self-reported and clinician-rated symptoms of PTSD and MDD. Results of exploratory factor analyses supported a 2-factor model representing symptoms of depression and PTSD; however, a subset of PTSD symptoms, characterized by emotional numbing and dysphoria, loaded onto the depression factor, rather than the PTSD factor. These nonspecific PTSD symptoms were predictive of comorbid MDD and increased depression symptomatology in patients with PTSD. Together, these findings demonstrate the importance of accounting for nonspecific symptoms in diagnosis and treatment of PTSD, highlighting a need for revisions to our current diagnostics.

Rationale: Survivors of acute lung injury (ALI) frequently have substantial depressive symptoms and physical impairment, but the longitudinal epidemiology of these conditions remains unclear. Objectives: To evaluate the 2-year incidence and duration of depressive symptoms and physical impairment after ALI, as well as risk factors for these conditions. Methods: This prospective, longitudinal cohort study recruited patients from 13 intensive care units (ICUs) in four hospitals, with follow-up 3, 6, 12, and 24 months after ALI. The outcomes were Hospital Anxiety and Depression Scale depression score greater than or equal to 8 (“depressive symptoms”) in patients without a history of depression before ALI, and two or more dependencies in instrumental activities of daily living (“impaired physical function”) in patients without baseline impairment. Measurements and Main Results: During 2-year follow-up of 186 ALI survivors, the cumulative incidences of depressive symptoms and impaired physical function were 40 and 66%, respectively, with greatest incidence by 3-month follow-up; modal durations were greater than 21 months for each outcome. Risk factors for incident depressive symptoms were education 12 years or less, baseline disability or unemployment, higher baseline medical comorbidity, and lower blood glucose in the ICU. Risk factors for incident impaired physical function were longer ICU stay and prior depressive symptoms. Conclusions: Incident depressive symptoms and impaired physical function are common and long-lasting during the first 2 years after ALI. Interventions targeting potentially modifiable risk factors (e.g., substantial depressive symptoms in early recovery) should be evaluated to improve ALI survivors’ long-term outcomes. PMID:22161158

Objectives: This study examined what percentage of Chinese mothers during a three-year postpartum period were screened for postpartum depression and explored the correlation between postpartum depression and various socio-demographic, psychological, and cultural factors. Study design: Cross-sectional survey. Methods: A total of 506 mothers 23 years of age and older who were within three years postpartum completed the online survey. The survey collected information such as family economic status, a history of depression, preparation for pregnancy, relationships with husbands, and family members, adult attachment types (Adult Attachment Scale, AAS), and depression (The Center for Epidemiologic Studies Depression Scale, CESD). Results: Approximately 30% of mothers 1–3 years postpartum reported symptoms above the CESD cut-off score (≥16 scores) associated with the risk for depression (28.0% in the first year, 30.8% in the second year, and 31.8% in the third year). Factors significantly associated with depression in participants in the correlation analysis were education level; family income; preparation for pregnancy; a history of depression; amount of time spent with their husbands; relationships with husbands, parents, and parents-in-law; and a close, dependent, and/or anxious attachment style. Multiple regression analyses revealed that a history of depression; less preparation for pregnancy; poorer relationships with husbands, parents, and parents-in-law; and a more anxious attachment style were strongly related to a higher risk of postpartum depression. Conclusion: The overall percentage of mothers after delivery who were vulnerable to depression in China remains high. Various factors were significant predictors of postpartum depression. The research findings have several valuable implications for intervention practices. For example, attachment styles and depression history in the assessments of perinatal depression could improve screenings and the design of interventions. Additionally, improving the family relationships and family environments of women post-delivery may be promising approach for postpartum depression prevention or intervention. PMID:27847483

Sex, trauma, stress hormones and depression.

Young, E; Korszun, A

Although few studies dispute that there are gender differences in depression, the etiology is still unknown. In this review, we cover a number of proposed factors and the evidences for and against these factors that may account for gender differences in depression. These include the possible role of estrogens at puberty, differences in exposure to childhood trauma, differences in stress perception between men and women and the biological differences in stress response. None of these factors seem to explain gender differences in depression. Finally, we do know that when depressed, women show greater hypothalamic-pituitary-adrenal (HPA) axis activation than men and that menopause with loss of estrogens show the greatest HPA axis dysregulation. It may be the constantly changing steroid milieu that contributes to these phenomena and vulnerability to depression.

Low-income African American mothers of young children experience high rates of depression, but many of the risk factors that have been identified provide little direction for intervention. The authors examined modifiable risk and protective factors for probable depression (Center for Epidemiological Studies Depression Scale >or= 23) in 824 African American mothers living in the 39 poorest census tracts in Detroit. Household food insufficiency and deteriorated housing significantly increased the odds of likely depression, whereas availability of a loan in a crisis, help with childcare, and transportation were protective. However, more frequent experiences of everyday discrimination greatly increased the odds of elevated depressive symptoms. These findings support the need for interventions that operate across individual and societal levels to address the fundamental causes of poor mental health.

[The genetics of depressive disorders].

Among the most common severe psychiatric disorders worldwide, depressive disorders are a leading cause of morbidity, the onset usually occurring during childhood or adolescence. Symptomatology, prevalence, outcome and treatment differentiate depressive disorder nosologically as being either unipolar depression or bipolar disorder, which is characterized by one or more episodes of mania with or without episodes of depression. Genetic factors decisively influence the susceptibility to depressive disorders. Family studies and twin studies have been essential in defining the magnitude of familial risk and liability to heritability, particularly in the case of bipolar disorder. In recent years, linkage and association studies have made great strides towards identifying candidate genes. Particularly the s-allele of the serotonin transporter has been repeatedly confirmed to be a risk factor. Meta-analyses suggest, however, that the genetic contributions of the ascertained loci are relatively small. Along with genetic factors, environmental factors are heavily involved. Gene-environment action plays a pivotal role, particularly in unipolar depression. The genetic disposition seems to be modulated by a protective or pathogenic environment. Early-onset disorders must be further investigated in future as studies to date are somewhat limited.

Objectives and Methods. The aim of the present study was to evaluate, by means of receiver operating characteristic (ROC) curves, whether cognitive vulnerabilities (CV), as measured by three well-known instruments (the Beck Hopelessness Scale, BHS; the Life Orientation Test-Revised, LOT-R; and the Attitudes Toward Self-Revised, ATS-R), independently discriminate between subjects with different severities of depression. Participants were 467 young adults (336 females and 131 males), recruited from the general population. The subjects were also administered the Beck Depression Inventory-II (BDI-II). Results. Four first-order (BHS Optimism/Low Standard; BHS Pessimism; Generalized Self-Criticism; and LOT Optimism) and two higher-order factors (Pessimism/Negative Attitudes Toward Self, Optimism) were extracted using Principal Axis Factoring analysis. Although all first-order and second-order factors were able to discriminate individuals with different depression severities, the Pessimism factor had the best performance in discriminating individuals with moderate to severe depression from those with lower depression severity. Conclusion. In the screening of young adults at risk of depression, clinicians have to pay particular attention to the expression of pessimism about the future.

Depression is the second most common chronic disorder seen by primary care physicians. Risk factors associated with depression include medical and psychosocial factors. While in Israel, the rate and risk factors for depression are considered similar to those in other Western countries, population-based data are limited. The present study aims to estimate the prevalence of depression among Jews and Muslim Arabs, and to consider possible associations with demographic, socioeconomic, and health factors. The study group (N = 872) was equally divided according to ethnicity, gender, and age group. Depression was measured by the Harvard Department of Psychiatry National Depression Screening Day Scale (HANDS). The rate of depression scores in the likely/very likely range was 2.5 times higher among Arabs than among Jews (24.9 vs. 10.6%; P < 0.001). Women were more likely to express symptoms of depressive episode than were men (22.0 vs. 13.6%; P = 0.001), and the depression rate increased with age, from 11.0% in the youngest group (26-35) to 25.0% in the oldest (P = 0.001). The rate of increase in depression by age was different for the genders, rising more steeply for women than for men. However, the age-gender differential was not identical for the two ethnic groups. The differences in depression prevalence between Arabs and Jews were maintained after controlling for confounding variables, except that when controlling for education, the difference between the ethnic groups was no longer significant. After adjusting for all variables in the analysis, no significant association remained between ethnicity and depression (OR = 0.80; 95% CI = 0.45-1.40).

Due to the heterogeneity of depressive symptoms-which can include depressed mood, anhedonia, negative cognitive biases, and altered activity levels-researchers often use a combination of depression rating scales to assess symptoms. This study sought to identify unidimensional constructs measured across rating scales for depression and to evaluate these constructs across clinical trials of a rapid-acting antidepressant (ketamine). Exploratory factor analysis (EFA) was conducted on baseline ratings from the Beck Depression Inventory (BDI), the Hamilton Depression Rating Scale (HAM-D), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Snaith-Hamilton Pleasure Rating Scale (SHAPS). Inpatients with major depressive disorder (n = 76) or bipolar depression (n = 43) were participating in clinical ketamine trials. The trajectories of the resulting unidimensional scores were evaluated in 41 subjects with bipolar depression who participated in clinical ketamine trials. The best solution, which exhibited excellent fit to the data, comprised eight factors: Depressed Mood, Tension, Negative Cognition, Impaired Sleep, Suicidal Thoughts, Reduced Appetite, Anhedonia, and Amotivation. Various response patterns were observed across the clinical trial data, both in treatment effect (ketamine versus placebo) and in degree of placebo response, suggesting that use of these unidimensional constructs may reveal patterns not observed with traditional scoring of individual instruments. Limitations include: 1) small sample (and related inability to confirm measurement invariance); 2) absence of an independent sample for confirmation of factor structure; and 3) the treatment-resistant nature of the population, which may limit generalizability. The empirical identification of unidimensional constructs creates more refined scores that may elucidate the connection between specific symptoms and underlying pathophysiology.

Symptoms of depression are present in a significant proportion of Alzheimer's disease (AD) patients. While epidemiological studies have shown a strong association between depression and AD, it has not been established whether depression is a risk factor or merely a co-morbidity of AD. It is also uncertain if depression affects the pathogenesis of AD. In this paper, we address these questions by measuring the serum levels of two common metabolic risk factors of AD and depression, inflammatory cytokines (IL 6 and TNF alpha) and serum 25-hydroxyvitamin D, in a case-control study. We measured the serum levels of IL 6, TNF α and 25-hydroxyvitamin D in age-matched healthy controls (n= 60) and in AD patients without depression (n=26) or AD patients with depression (n=34), and statistically analyzed the changes in these parameters among different groups under this study. Our results show that in AD there is a significant increase in IL 6 and TNF α and a marked decrease in 25-hydroxyvitamin D in the peripheral circulation compared to age-matched healthy controls. Furthermore, AD patients with depression have even significantly higher levels of IL 6 or TNF α and a lower level of 25-hydroxyvitamin D in circulation than in AD patients without depression. We also found a strong statistical correlation between the disease severity and the serum levels of IL 6, TNF α and 25-hydroxyvitamin D in AD patients with depression. These results suggest that altered circulating levels of common metabolic risk factors lead to the co-existence of depression with AD in many patients, and when they co-exist, the depression presumably affects the severity of AD presentations through more aggravated changes in these risk factors.

In Japan, Kraepelin's descriptions on four "fundamental states" of manic depressive illness, the concepts of schizoid temperament by Kretschmer and obsessional and melancholic type temperament by Shimoda and Tellenbach have been widely accepted. This research investigates the construct validity of these temperaments through factor analysis. TEMPS-A measured depressive, cyclothymic, hyperthymic and irritable temperaments and MPT rigidity, esoteric and isolation subscales measured, respectively, melancholic type and schizoid temperaments. Factor analysis was implemented with TEMPS-A alone and TEMPS-A and MPT combined data. With TEMPS-A alone analysis, Factor 1 included 1 depressive, 11 cyclothymic and 12 irritable temperament items with a factor loading higher than 0.4; Factor 2 included 1 depressive and 10 hyperthymic temperament items; and Factor 3 included 2 depressive temperament items only. With TEMPS-A and MPT combined data, Factor 1 included 3 depressive, 11 cyclothymic and 5 irritable temperament items with a factor loading higher than 0.4 (interpreted as the central cyclothymic tendency for all affective temperaments along Kretschmerian lines and accounting for 11.7% of the variance); Factor 2 included 6 hyperthymic temperament items (6.22% of variance); Factor 3 included 1 cyclothymic, 7 irritable and 1 schizoid temperament items (interpreted as the irritable temperament and accounting for 3.24% of the variance); Factor 4 included 1 depressive temperament and 5 melancholic type items (interpreted as the latter, accounting for 2.66% of the variance); Factor 5 included 5 depressive temperament items, along interpersonal sensitivity and passivity lines, and accounting for 2.31% of the variance; and Factor 6 included 4 schizoid temperament items accounting for 2.07% of the variance. We did not use the Kasahara scale, which some believe to better capture the Japanese melancholic type. Sample was 70% male. These analyses confirm the factor validity of depressive, hyperthymic, cyclothymic and irritable temperaments (TEMPS-A), as well as the melancholic type and the schizoid temperament (MPT). Traits of the depressive and melancholic types emerge as rather distinct. Indeed, our results permit the delineation of an interpersonally sensitive type that "gives in to others" as the core features of the depressive temperament; this is to be contrasted with the higher functioning, perfectionistic, work-oriented melancholic type. Mood dysregulation is represented by the largest number of traits in this population. Contrary to a widely held belief that the melancholic type with its devotion to work and to others is the signature temperament in Japan, cyclothymic traits account for the largest variance in this nonclinical population. Hyperthymic temperament, melancholic type and schizoid temperaments appear largely independent of mood dysregulation. In this Japanese population, TEMPS-A may identify temperament constructs more comprehensively when implemented with melancholic type and schizoid temperament question items added to it. The proposed new Japanese Temperament and Personality (JTP) Scale has self-rated items divided into six subscales.

Social, political and economic changes in Mongolia have followed post-Soviet style government policies and contributed to both increased liberalisation and reduced security in employment and family finances. This is the first study to attempt to assess the prevalence of depression in a population of Mongolian women in the post-partum period and assess risk factors, including financial position, associated with the condition. A total of 1044 women who had delivered healthy babies in Ulaanbaatar between October and December 2002 were screened for depression using the WHO Self Reporting Questionnaire between 5 and 9 weeks post-partum. Further details on the mother, her family and social and economic circumstances were simultaneously collected. Analysis of risk factors for probable depression was undertaken using multiple logistic regression techniques. The prevalence of depression was 9.1% (95% CLs 7.5%-11.1%). Variables significantly and independently associated with risk of probable maternal depression included economic factors, mother being subject to physical abuse, dissatisfied with the pregnancy, concerned about her baby's behaviour, and her own health problems. The sample was drawn from a population of mothers all of whom had healthy, full-term babies of normal birth weight. Clinical confirmation of diagnosis was not established. Mongolian women with young infants in Ulaanbaatar probably experience depression at rates comparable with other cultures. Factors associated with probable depression were dominated by health, relationships and financial position.

Latinos, the largest minority group in the United States, experience mental health disparities, which include decreased access to care, lower quality of care and diminished treatment engagement. The purpose of this cross-sectional study of 177 Latino immigrants in primary care is to identify demographic factors, attitudes and beliefs, such as stigma, perceived stress, and ethnic identity that are associated with depression, help-seeking and self-recognition of depression. Results indicated that 45 participants (25%) had depression by Patient Health Questionnaire (PHQ-9) criteria. Factors most likely to be associated with depression were: poverty; difficulty in functioning; greater somatic symptoms, perceived stress and stigma; number of chronic illnesses; and poor or fair self-rated mental health. Fifty-four people endorsed help-seeking. Factors associated with help-seeking were: female gender, difficulty in functioning, greater somatic symptoms, severity of depression, having someone else tell you that you have an emotional problem, and poor or fair self-rated mental health. Factors most likely to be associated with self-recognition were the same, but also included greater perceived stress. This manuscript contributes to the literature by examining attitudinal factors that may be associated with depression, help-seeking and self-recognition among subethnic groups of Latinos that are underrepresented in research studies.

The Edinburgh Postnatal Depression Scale (EPDS) is a widely used screening tool for postpartum depression (PPD). Although the reliability and validity of EPDS in Japanese has been confirmed and the prevalence of PPD is found to be about the same as Western countries, the factor structure of the Japanese version of EPDS has not been elucidated yet. 690 Japanese mothers completed all items of the EPDS at 1 month postpartum. We divided them randomly into two sample sets. The first sample set (n = 345) was used for exploratory factor analysis, and the second sample set was used (n = 345) for confirmatory factor analysis. The result of exploratory factor analysis indicated a three-factor model consisting of anxiety, depression and anhedonia. The results of confirmatory factor analysis suggested that the anxiety and anhedonia factors existed for EPDS in a sample of Japanese women at 1 month postpartum. The depression factor varies by the models of acceptable fit. We examined EPDS scores. As a result, "anxiety" and "anhedonia" exist for EPDS among postpartum women in Japan as already reported in Western countries. Cross-cultural research is needed for future research.

Comorbidity of depression in Parkinson disease (PD) is a major factor that changes patients' quality of life. However, the neurobiological and sociodemographic risk factors for this comorbidity are not well studied. In this study, we aimed to define the prevalence, temporal relationship, and psychosocial and clinical determinants of depression comorbid with PD. Fifty-five PD patients were evaluated with SCID, a data form that assessed sociodemographic and PD-related variables, UPDRS III, HAM-D, HAM-A, MMSE, and the Apathy Evaluation Scale. Depression (lifetime: 45.5%, last month: 25.5%, before PD: 20%) was the most frequent psychiatric diagnosis. The major determinants of depression in the last month and depression before PD were early onset of PD and young age. Patients on pramipexole treatment were less likely to be diagnosed with depression in the last month. Other sociodemographic and PD-related variables were not significantly different for lifetime, last month, and pre-PD depression diagnosis compared to their counterparts. Depression is prevalent both before and after patient gets a PD diagnosis. Depression is not only the result of PD-related life changes but it is also a preceding factor that may decrease the age of PD onset.

Depression may manifest differently across cultural settings, suggesting the value of an assessment tool that is sensitive enough to capture these variations. The study reported in this article aimed to develop a depression screening tool for Indonesians derived from ethnographic interviews with 20 people who had been diagnosed as having depression by clinical psychologists at primary health centers. The tool, which we have termed the Indonesian Depression Checklist (IDC), consists of 40 items. The tool was administered to 125 people assessed to have depression by 40 clinical psychologists in primary health centers. The data were analyzed with Confirmatory Factor Analysis (CFA) (IBM SPSS AMOS Software). CFA identified a five-factor hierarchical model ( χ 2  = 168.157, p = .091; CFI = .963; TLI = .957; RMSEA = .036). A 19-item inventory of the IDC, with five factors - Physical Symptoms, Affect, Cognition, Social Engagement and Religiosity - was identified. There was a strong correlation between the total score of the IDC and total score of the Center for Epidemiological Studies-Depression scale (revised version CES-D), a standard tool for assessing symptoms of depression. The IDC accommodates culturally distinctive aspects of depression among Indonesians that are not included in the CES-D.

To examine the role of demographic, illness-related, workplace support, workplace activity limitations, arthritis-related work changes, and psychosocial factors in predicting subsequent depressive symptoms among employed people with arthritis. In a prospective study, 366 employed individuals with arthritis were recruited from Toronto, Canada. Respondents completed a structured questionnaire assessing demographic, disease-related factors, workplace support, and employment-related transitions, as well as psychosocial variables at 2 timepoints 18 months apart. Depression was assessed using the Center for Epidemiologic Studies Depression Scale. Hierarchical multiple regression was used for analyses. Individuals with greater education reported significantly less depression. Lower workplace support and greater workplace activity limitations were significantly associated with future depressive symptoms. No relationship was found between work transitions and later depression, but more work changes were strongly associated with concurrent depressive symptoms. An association was also found between greater pain catastrophizing and future depressive symptoms. Our results highlight the need to assess the influence of work-related changes, workplace support, and psychosocial variables on depressive symptoms among people with arthritis. These findings suggest that workplace interventions should address not only ways to reduce workplace activity limitations, but also ways to better manage emotional distress related to working with arthritis.

Depression has been identified as a priority disorder among children and adolescents. While numerous reviews have examined the individual and family factors that contribute to child and adolescent depressive symptoms, less is known about community-level risk and protective factors. The aim of this study was to complete a systematic review to identify community risk and protective factors for depression in school-aged children (4-18 years). The review adopted the procedures recommended by the Cochrane Non-Randomised Studies Methods Working Group and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was conducted to identify both observational and intervention study designs in both peer-reviewed and non-peer reviewed publications. A total of 21 studies met the inclusion criteria. Seventeen of the 18 community association studies and 2 of the 3 intervention studies reported one or more significant effects. Results indicated that community safety and community minority ethnicity and discrimination act as risk factors for depressive symptoms in school-aged children. Community disadvantage failed to achieve significance in meta-analytic results but findings suggest that the role of disadvantage may be influenced by other factors. Community connectedness was also not directly associated with depressive symptoms. There is evidence that a number of potentially modifiable community-level risk and protective factors influence child and adolescent depressive symptoms suggesting the importance of continuing research and intervention efforts at the community-level. © The Royal Australian and New Zealand College of Psychiatrists 2015.

We investigated the role of genetic and environmental factors in the developmental association among symptoms of eating disorders, depression, and anxiety syndromes in 8-13-year-old and 14-17-year-old twin girls. Multivariate genetic models were fitted to child-reported longitudinal symptom data gathered from clinical interview on 408 MZ and 198 DZ female twin pairs from the Virginia Twin Study of Adolescent Behavioural Development (VTSABD). Model-fitting revealed distinct etiological patterns underlying the association among symptoms of eating disorders, depression, overanxious disorder (OAD), and separation anxiety disorder (SAD) during the course of development: 1) a common genetic factor influencing liability to all symptoms - of early and later OAD, depression, SAD, and eating symptoms; 2) a distinct genetic factor specifically indexing liability to early eating disorders symptoms; 3) a shared environmental factor specifically influencing early depression and early eating disorders symptoms; and 4) a common environmental factor affecting liability to symptoms of later eating disorders and both early and later separation anxiety. These results suggest a pervasive genetic effect that influences liability to symptoms of over-anxiety, separation anxiety, depression, and eating disorder throughout development, a shared environmental influence on later adolescent eating problems and persistent separation anxiety, genetic influences specific to early eating disorders symptoms, and a shared environmental factor influencing symptoms of early eating and depression.

Background: Suicide rates are high among African American students because they are at a greater risk of depression. A commonly used suicide prevention approach is the gatekeeper training. However, gatekeeper training is neither evidence-based nor has it been identified as culturally-appropriate for African American college students. Therefore, the purpose of this study was to develop and evaluate an online peer-to-peer PRECEDE-PROCEED model based depression awareness and suicide prevention program that was culturally appropriate for African American college students. Methods: The setting was a predominantly Black institution in southern USA. A pre-experimental repeated measures one group design was used to measure changes in peer educators' (n = 29) predisposing factors regarding knowledge, skills and attitudes pertaining to depression, reinforcing factors or receiving support from peers, healthcare professionals and teachers to help someone with depression, enabling factors or sureness of finding organizations to help someone with depression, and behavior for helping someone with depression at pretest, posttest and 1-month follow-up. A posttest only one group design was also used to measure effect on predisposing factors and behavior of students (n = 300) trained by peer educators. Results: There were statistically significant improvements in attitudes related to depression as disease (P = 0.003; η 2 = 0.39), attitudes about managing depression (P = 0.0001; η 2 = 0.30), skills(P = 0.0001; η 2 = 0.41), reinforcing factors (P = 0.018; η 2 = 0.13), enabling factors (P = 0.0001;η 2 = 0.31), and behavior (P = 0.016; η 2 = 0.14). Changes in knowledge about depression and attitudes about helping people with depression were not statistically significant over time for peer educators. The peer-to-peer training was not completely effective in transferring corresponding changes for students trained by peers. Conclusion: The program was effective for peer educators but peers could not significantly influence other students in all domains. This study provides a starting point toward evidencebased approaches for health promotion interventionists addressing depression awareness and suicide prevention among African American college students.

Women are seriously subjected to psychiatric diseases during pregnancy and depression is the most prevailing one among these diseases. There is a relation between the social support and depression in pregnancy whose predisposing factors are genetic, psychological, biological, environmental, and hormonal. This study aimed to determine the frequency of depression symptoms, and its risk factors. Also it studied the correlation between social support and pregnancy depression. This research is a descriptive cross-sectional study. It was conducted on 266 pregnant women selected by simple random method from all pregnant women admitted at the Maternity Hospital of Trabzon, Turkey from May 21 to June 13, 2008. The data were collected with a questionnaire form, the Beck depression inventory (BDI), and the multidimensional scale of perceived social support (MSPSS). The mean BDI score of the pregnant women was 11.12 ± 6.65. According to the BDI, 46.2% of the pregnant women had no depression symptoms, 34.59% of them had mild, 13.91% had moderate, and 4.89% had severe level of depression symptoms. It was found that such factors as the educational level of the pregnant women and their husbands, having an undesired pregnancy, suffering from a chronic disease before pregnancy, presence of pregnancy-related problems, having a child with disability or having relatives whose children had disability, and smoking during pregnancy were the risk factors affecting the severity of the depression symptoms and these results were statistically significant (P < 0.05). On the other hand, the mean MSPSS score was 67.89 ± 14.26 and it was found that the pregnant women got the highest social support from their husbands. It was found that there was a significant correlation between BDI and MSPSS total score and its subscale scores (P < 0.05). According to this study, one-fifth of pregnant women were found to experience depressive symptoms, which require treatment during pregnancy, and the factors such as having no support from relatives was found to be associated with the severity of depressive symptoms during pregnancy.

There is a pressing need for reliable and valid rating scales to assess and measure depression in individuals at ultra-high risk (UHR) of psychosis. The aim of this study was to examine the clinical utility of the Calgary Depression Scale for Schizophrenia (CDSS) in individuals at UHR of psychosis. 167 individuals at UHR of psychosis were included as participants in this study. The Structured Clinical Interview for DSM-IV Axis I Disorders, CDSS, Beck Anxiety Inventory and Global Assessment of Functioning were administered. A receiver operating characteristic (ROC) curve analysis and factor analyses were performed. Cronbach's alpha was computed. Correlations between CDSS factor scores and other clinical variables were examined. The median CDSS total score was 5.0 (IQR 1.0-9.0). The area under ROC curve was 0.886 and Cronbach's alpha was 0.855. A score of 7 on the CDSS yielded the highest sensitivity and specificity in detecting depression in UHR individuals. Exploratory factor analysis of the CDSS yielded two factors: depression-hopelessness and self depreciation-guilt, which was confirmed by confirmatory factor analysis. Further analysis showed that the depression-hopelessness factor predicted functioning; whereas the self depreciation-guilt factor was related to the severity of the attenuated psychotic symptoms. In conclusion, the CDSS demonstrates good psychometric properties when used to evaluate depression in individuals at UHR of psychosis. Our study results also support a two-factor structure of the CDSS in UHR individuals. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

Depression is a mental health state whose frequency has been increasing in modern societies. It imposes a great burden, because of the strong impact on people's quality of life and happiness. Depression can be reliably diagnosed and treated in primary care: if more people could get effective treatments earlier, the costs related to depression would be reversed. The aim of this study was to examine the influence of socio-economic factors and gender on depressed mood, focusing on Korea. In fact, in spite of the great amount of empirical studies carried out for other countries, few epidemiological studies have examined the socio-economic determinants of depression in Korea and they were either limited to samples of employed women or did not control for individual health status. Moreover, as the likely data endogeneity (i.e. the possibility of correlation between the dependent variable and the error term as a result of autocorrelation or simultaneity, such as, in this case, the depressed mood due to health factors that, in turn might be caused by depression), might bias the results, the present study proposes an empirical approach, based on instrumental variables, to deal with this problem. Data for the year 2008 from the Korea National Health and Nutrition Examination Survey (KNHANES) were employed. About seven thousands of people (N= 6,751, of which 43% were males and 57% females), aged from 19 to 75 years old, were included in the sample considered in the analysis. In order to take into account the possible endogeneity of some explanatory variables, two Instrumental Variables Probit (IVP) regressions were estimated; the variables for which instrumental equations were estimated were related to the participation of women to the workforce and to good health, as reported by people in the sample. Explanatory variables were related to age, gender, family factors (such as the number of family members and marital status) and socio-economic factors (such as education, residence in metropolitan areas, and so on). As the results of the Wald test carried out after the estimations did not allow to reject the null hypothesis of endogeneity, a probit model was run too. Overall, women tend to develop depression more frequently than men. There is an inverse effect of education on depressed mood (probability of -24.6% to report a depressed mood due to high school education, as it emerges from the probit model marginal effects), while marital status and the number of family members may act as protective factors (probability to report a depressed mood of -1.0% for each family member). Depression is significantly associated with socio-economic conditions, such as work and income. Living in metropolitan areas is inversely correlated with depression (probability of -4.1% to report a depressed mood estimated through the probit model): this could be explained considering that, in rural areas, people rarely have immediate access to high-quality health services. This study outlines the factors that are more likely to impact on depression, and applies an IVP model to take into account the potential endogeneity of some of the predictors of depressive mood, such as female participation to workforce and health status. A probit model has been estimated too. Depression is associated with a wide range of socio-economic factors, although the strength and direction of the association can differ by gender. Prevention approaches to contrast depressive symptoms might take into consideration the evidence offered by the present study. © 2015 by Kerman University of Medical Sciences.

The extracellular signal-regulated kinase/cAMP response element-binding protein/brain-derived neurotrophic factor signal transduction pathway plays an important role in the mechanism of action of antidepressant drugs and has dominated recent studies on the pathogenesis of depression. In the present review we summarize the known roles of extracellular signal-regulated kinase, cAMP response element-binding protein and brain-derived neurotrophic factor in the pathogenesis of depression and in the mechanism of action of antidepressant medicines. The extracellular signal-regulated kinase/cAMP response element-binding protein/brain-derived neurotrophic factor pathway has potential to be used as a biological index to help diagnose depression, and as such it is considered as an important new target in the treatment of depression.

HIV-positive men who have sex with men (HIVMSM) face severe stigma and high levels of stressors, and have high prevalence of mental health problems (e.g., depression and anxiety). Very few studies explored the role of positive psychological factors on mental health problems among HIVMSM. The present study investigated the prevalence of two mental health problems (anxiety and depression), and their associated protective (gratitude) and risk (enacted HIV-related stigma, and perceived stress) factors among HIVMSM in China. A cross-sectional survey was conducted among 321 HIVMSM in Chengdu, China, by using a structured questionnaire. Over half (55.8%) of the participants showed probable mild to severe depression (as assessed by the Center of Epidemiologic Studies Depression scale); 53.3% showed probable anxiety (as assessed by the General Anxiety Disorder scale). Adjusted logistic regression models revealed that gratitude (adjusted odds ratio (ORa = 0.90, 95% confidence intervals (95% CI) = 0.86-0.94) was found to be protective, whilst perceived stress (ORa = 1.17, 95% CI = 1.12-1.22) and enacted stigma (ORa = 7.72, 95% CI = 2.27-26.25) were risk factors of depression. Gratitude (ORa = 0.95, 95% CI = 0.91-0.99) was also found to be protective whilst perceived stress (ORa = 1.19, 95% CI = 1.14-1.24) was a risk factor of anxiety. Gratitude did not moderate the associations found between related factors and poor mental health. It is warranted to promote mental health among HIVMSM, as depression/anxiety was highly prevalent. Such interventions should consider enhancement of gratitude, reduction of stress, and removal of enacted stigma as potential strategies, as such factors were significantly associated with depression/anxiety among HIVMSM.

In the last few years, it has been found that transverse waves are present at all times in coronal loops or spicules. Their energy has been estimated with an expression derived for bulk Alfvén waves in homogeneous media, with correspondingly uniform wave energy density and flux. The kink mode, however, is localized in space with the energy density and flux dependent on the position in the cross-sectional plane. The more relevant quantities for the kink mode are the integrals of the energy density and flux over the cross-sectional plane. The present paper provides an approximation to the energy propagated bymore » kink modes in an ensemble of flux tubes by means of combining the analysis of single flux tube kink oscillations with a filling factor for the tube cross-sectional area. This finally allows one to compare the expressions for energy flux of Alfvén waves with an ensemble of kink waves. We find that the correction factor for the energy in kink waves, compared to the bulk Alfvén waves, is between f and 2f, where f is the density filling factor of the ensemble of flux tubes.« less

Depression is a common health problem in elderly nursing home (NH) residents and is often under-recognized and under-treated. This study aimed to determine the prevalence rates of depression and identify the risk factors associated with depression in the elderly NH population in Singapore. A sample of 375 residents in six NHs in Singapore, aged 55 years and above, was assessed with the Structural Clinical Interview (SCID), based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) criteria. The association of demographic, functional and health-related characteristics with depression was examined using multivariate logistic regression analyses. Overall point prevalence for depression in the elderly NH residents was found to be 21.1% (95% confidence intervals (CI): 17.1%-25.6%). The prevalence rate for minor depression in the elderly NH residents was 14.4% (95% CI: 11.1%-18.5%) and 6.7% (95% CI: 4.5%-9.8%) for major depression. Significant risk factors that were found to be associated with depression were length of stay for more than 2 years, known history of depression, pain, and no or lack of social contact. The prevalence rates for depression were high among NH residents in Singapore. More attention is needed to care for the psychosocial needs of elderly NH residents in Singapore.

Differentiating Burnout from Depression: Personality Matters!

Stress-related affective disorders have been identified as a core health problem of the twenty-first century. In the endeavor to identify vulnerability factors, personality has been discussed as a major factor explaining and predicting disorders like depression or burnout. An unsolved question is whether there are specific personality factors allowing differentiation of burnout from depression. The present study tested the relation between one of the most prominent, biological personality theories, Cloninger’s Temperament and Character Inventory, and common measures of burnout (Maslach Burnout Inventory General) and depression (Beck Depression Inventory 2) in a sample of German employees (N = 944) and a sample of inpatients (N = 425). Although the same personality traits (harm avoidance and self-directedness) were predominantly associated with burnout and depression, there was a much stronger association to depression than to burnout in both samples. Besides, we observed specific associations between personality traits and subcomponents of burnout. Our results underline differences in the association of burnout vs. depression to personality, which may mirror differences in scope. While symptoms of depression affect all aspects of life, burnout is supposed to be specifically related to the workplace and its requirements. The much stronger association of personality to depression can be important to select appropriate therapy methods and to develop a more specified treatment for burnout in comparison to depression.

During initial assessment of individuals with schizophrenia and related disorders (schizophrenia spectrum disorders [SSDs]), clinicians tend to pay greater attention to psychotic symptoms than mood symptoms, including depression. Depression is reported to influence the course of SSDs, but not much is known about the risk factors for depression in SSDs. In the present study, we examined clinical predictors of depression in SSDs. The sample included 71 patients with SSDs followed in a modified Assertive Community Treatment program, the Community Support Network of Springfield, Illinois. The study design was naturalistic, prospective, and longitudinal (mean follow-up = 8.3 years; SD = 7.3). The GENMOD procedure appropriate for repeated measures analysis with dichotomous outcome variables followed longitudinally was computed. Rates of depression ranged from 18% to 41% over the differing assessment periods. Schizophrenia and schizoaffective disorder did not vary by depression rate. Depression independent of SSD diagnosis was associated with greater hospitalization rates. Clinical variables predict- ing depression were auditory hallucinations, delusions, poor insight, and poor judgment. Psychotic symptoms in the course of SSDs are risk factors for depression. As a consequence, the mental status examination of patients with SSDs with active psychosis should include assessment of mood changes. Further research is warranted to determine if treatment of depression among patients with SSDs may reduce their rates of hospitalization.

Diagnosing depression in chronic pain is challenging due to overlapping somatic symptoms. In questionnaires, such as the Beck Depression Inventory (BDI), responses may be influenced more by pain than by the severity of depression. In addition, previous studies have suggested that symptoms of negative self-image, a key element in depression, are uncommon in chronic pain-related depression. The object of this study is to assess the relationship of the somatic and cognitive-emotional items of BDI with the diagnosis of depression, pain intensity, and disability. One hundred consecutive chronic pain patients completed the Structured Clinical Interview for DSM Disorders (SCID) for the diagnosis of major depressive disorder (MDD) according to DSM-IV. Two subscales of BDI (negative view of self and somatic-physical function) were created according to the factor model presented by Morley. In the regression analysis, the somatic-physical function factor associated with MDD, while the negative view of self factor did not. Patients with MDD had higher scores in several of the BDI items when analysed separately. Insomnia and weight loss were not dependent on the depression diagnosis. The relatively small sample size and the selected patient sample limit the generalisability of the results. Somatic symptoms of depression are also common in chronic pain and should not be excluded when diagnosing depression in pain patients. Regardless of the assessment method, diagnosing depression in chronic pain remains a challenge and requires careful interpretation of symptoms.

This study examines symptoms of subthreshold depression among older adults in congregate housing, compared with their nondepressed peers, and tests a conceptual model of subthreshold depression. Hypotheses included that subthreshold depression would be characterized and distinguished by low energy, social withdrawal, and depletion, rather than sadness, and that subthreshold depressed elders would be distinguished by poorer health and functioning, loneliness, and grieving a recent loss. A self-administered survey was followed by a diagnostic interview by telephone to (N = 166) white and African-American residents of independent and assisted living apartments from six retirement communities, average age 82.9 years. The Mini International Neuropsychiatric Interview (MINI) determined depression status. The 30-item Geriatric Depression Scale was used to measure symptoms. Forty-six individuals (27.7%) were identified as subthreshold depressed, seven as suffering from major depression, and 113 as non-depressed. Subthreshold depression was characterized by low energy, difficulty with initiative, worries about the future, lack of positive affect, sadness and irritability. Negative affect symptoms such as sadness and irritability best discriminated the subthreshold group from the nondepressed. Risk factors for subthreshold depression in this sample included less education, lower socio-economic status, African-American race, grieving, and social loneliness. Subthreshold depression in this group of residents of congregate housing was similar to the depletion experienced by many nondepressed elders, but further characterized by negative affect and lack of hope for the future. Social factors, such as socioeconomic status and personal losses, constituted greater risks for subthreshold depression than did health and functioning.

Prevalence of depressive disorders in Rasht, Iran: A community based study

PubMed Central

2008-01-01

Introduction Depression is a well known health problem worldwide. Prevalence of depressive disorders varies in different societies. Aim to determine the prevalence of depressive disorders and some associated factors in Rasht City (Northern part of Iran). Materials and methods 4020 subjects were selected among 394925 residents of Rasht aged between 18–70 during 2003 – 2004. In the first phase, subjects were screened by Beck's Depression Inventory. In the second phase, those who scored more than 15 were assessed through semi-structured psychiatric interview (DSMIV-TR). Socio-demographic characteristics including age, gender, marital status, educational level, and socio-economic class were recorded as well. Results 9.5% of samples (63% female and 37% male) were diagnosed by depressive disorders. The prevalence of minor depressive disorder, dysthymia and major depressive disorder was 5%, 2/5%, and 1% respectively. Socio-economic class was significantly associated with both depressive symptoms based on BDI score (p < 0.001) and depressive disorders based on clinical interview (p < 0.001). Conclusion Comparing to other studies, this study revealed that prevalence of dysthymic and minor depressive disorder were more than major depressive disorder, and low socio-economic class was the most significant risk factor associated with depression. Regarding our study limitations, researchers and policy makers should not consider our findings as conclusive results. Findings of this study could be applied by researchers using analytical methodology to assess relationship between depressive disorders and associated factors. PMID:18601715

Lifestyle determinants of depressive state and a feeling of unhappiness in daily life were evaluated among the workers in Japan by adjusting obesity and age. A total of 3630 men aged 34 to 60 years from a workplace in Japan participated in this cross-sectional study conducted in 2006. The prevalence of depressive state and a feeling of unhappiness were evaluated by a questionnaire with questions pertaining to the age, body mass index, and six lifestyle factors. The six lifestyle factors were frequency of exercise and alcohol intake per week, smoking habit, hours of sleep per day, and frequency of eating breakfast and snack per week. The associations between depressive state and/or a feeling of unhappiness and the lifestyle factors were tested by logistic regression analysis. The prevalence of depressive state and a feeling of unhappiness among the workers was 8.1% and 20.3%, respectively. The prevalence of workers who sleep at least for 6 hours on average, exercise regularly and eat breakfast everyday increased as the age of the workers increased. Depressive state and a feeling of unhappiness were significantly associated with age and a reduced duration of sleep even after adjustment for the other variables. No significant associations were found between the other lifestyle factors examined and depressive state and/or a feeling of unhappiness. Depressive state and/or a feeling of unhappiness were significantly associated with a reduced duration of sleep among the workers. Aging was a preventative factor of depressive state and/or a feeling of unhappiness. The effect of obesity was adjusted in this study, but the cause-effect relation between lifestyles and depressive state and/or a feeling of unhappiness should be clarified by the follow-up study.

Depression in adults is associated with risk factors for cardiovascular disease (CVD). It is unclear, however, when the association between clinical depression and cardiac risk factors develops or how early in life this association can be detected. In an ongoing study of pediatric depression, we compared CVD risk factors including smoking, obesity, physical activity level, sedentary behavior, and parental history of CVD across three samples of adolescents: probands with established histories of childhood-onset major depressive disorder (n = 210), never-depressed siblings of probands (n = 195), and controls with no history of any major psychiatric disorder (n = 161). When assessed during adolescence, 85% of the probands were not in a major depressive episode. Nevertheless, at that assessment, probands had a higher prevalence of regular smoking (odds ratio [OR] = 12.54, 95% confidence interval [CI] = 4.36-36.12) and were less physically active than controls (OR = 0.59, CI = 0.43-0.81) and siblings (OR = 0.70, CI = 0.52-0.94) and had a higher rate of obesity than did controls (OR = 3.67, CI = 1.42-9.52). Parents of probands reported high rates of CVD (significantly higher than did parents of controls), including myocardial infarction and CVD-related hospitalization (ORs = 1.62-4.36, CIs = 1.03-15.40). Differences in CVD risk factors between probands and controls were independent of parental CVD. Major depression in childhood is associated with an unfavorable CVD risk profile in adolescence, and risks for pediatric depression and CVD may coincide in families. Effective prevention and treatment of childhood depression may be a means to reduce the incidence of adult CVD.

The aim of the study reported here is to explore ecological covariate and latent variable associations with perinatal depressive symptoms in South Western Sydney for the purpose of informing subsequent theory generation of perinatal context, depression, and the developmental origins of health and disease. Mothers (n = 15,389) delivering in 2002 and 2003 were assessed at two to three weeks after delivery for risk factors for depressive symptoms. The binary outcome variables were Edinburgh Postnatal Depression Scale (EPDS)> 9 and > 12. Aggregated EPDS > 9 was analyzed for 101 suburbs. Suburb-level variables were drawn from the 2001 Australian Census, New South Wales Crime Statistics, and aggregated individual-level risk factors. Analysis included exploratory factor analysis, univariate and multivariate likelihood, and Bayesian linear regression with conditional autoregressive components. The exploratory factor analysis identified six factors: neighborhood adversity, social cohesion, health behaviors, housing quality, social services, and support networks. Variables associated with neighborhood adversity, social cohesion, social networks, and ethnic diversity were consistently associated with aggregated depressive symptoms. The findings support the theoretical proposition that neighborhood adversity causes maternal psychological distress and depression within the context of social buffers including social networks, social cohesion, and social services.

It has been reported that the risk of depression is higher among people with type 2 diabetes compared with a nondiabetic population. Among diabetic patients, depression has been associated with worse self-care behaviors, poor glycemic control, and an increased risk of diabetes complications. Identifying factors associated with the occurrence of depression may help physicians identify earlier diabetic patients at a high risk of developing depression, improve prevention, and accelerate proper treatment. To our knowledge, very few population-based studies have reported on the incidence of clinically diagnosed depression as a consequence of type 2 diabetes over a long follow-up period. The objective of this study was to estimate the incidence of clinically diagnosed depression among type 2 diabetic patients newly treated with oral antidiabetic drugs (ADs) and to identify factors associated with the occurrence of depression.Administrative claims data from the public health insurance plan were used to identify a cohort of new oral AD users aged ≥18 years between 2000 and 2006. Patients were followed from oral AD treatment initiation until the diagnosis of depression, ineligibility for the public drug plan, death, or the end of the study, whichever came first. Incidence rates were determined using person-time analysis. Factors associated with depression were identified using multivariable Cox regression analysis.We identified 114,366 new oral AD users, of which 4808 had a diagnosis of depression. The overall incidence rate of depression was 9.47/1000 person-years (PYs) (10.72/1000 PYs for women and 8.27/1000 PYs for men). The incidence of depression was higher during the year after oral AD treatment initiation. Independent factors associated with depression included having had mental disorders other than depression, hospitalization, a higher number of different drugs taken and of physicians visited during the year before oral AD initiation. Moreover, we observed a statistically significant age-by-socioeconomic status interaction.The incidence of diagnosed depression is higher during the first year after oral AD treatment initiation. Clinicians could pay particular attention to women, patients starting an AD at a young age, those with a low socioeconomic status, and especially those with a history of anxiety or dementia.

Is introversion a risk factor for suicidal behaviour in depression?

PubMed

Roy, A

1998-11-01

Personality is an important determinant of suicidal behaviour. However, it has been studied little in relation to suicidal behaviour in depression. Depressed patients who had attempted suicide (N = 41) were compared with depressed patients who had never attempted suicide (N = 56) and normal controls (N = 56) for their scores on three personality questionnaires. Introversion was the only personality dimension where the post hoc test showed a different pattern between the two groups of depressed patients in their relation to controls. In particular, only depressed patients who had attempted suicide had significantly lower introversion scores than controls. The personality dimension of introversion may be a risk factor for suicidal behaviour in depression.

Stress is associated with the onset of depressive episodes, and cortisol hypersecretion is considered a biological risk factor of depression. However, the possible mechanisms underlying stress, cortisol and depressive behaviours are inconsistent in the literature. This study examined the interrelationships among stress, cortisol and observed depressive behaviours in female rhesus macaques for the first time and explored the possible mechanism underlying stress and depressive behaviour. Female monkeys were video-recorded, and the frequencies of life events and the duration of huddling were analysed to measure stress and depressive behaviour. Hair samples were used to measure chronic cortisol levels, and the interactions between stress and cortisol in the development of depressive behaviour were further evaluated. Significant correlations were found between stress and depressive behaviour measures and between cortisol levels and depressive behaviour. Stress was positively correlated with cortisol levels, and these two factors interacted with each other to predict the monkeys’ depressive behaviours. This finding extends the current understanding of stress/cortisol interactions in depression, especially pertaining to females. PMID:27443987

The study compared knowledge and beliefs about depression among urban and rural Chinese in a Malaysian sample. A total of 409 participants were asked to identify cases of depression varying in intensity from two vignettes and rate their beliefs regarding a list of possible causes and treatments for depression. The urban Chinese were more likely to identify depression as the problem in the vignette. Beliefs about causes of depression were factored into five components, whereas beliefs about treatment for depression factored into four components. The results indicated that the causes most strongly endorsed were stress and pressure, and standard treatments rated the highest as treatments for depression. Overall, depression literacy was moderate for Chinese Malaysians. The results are discussed in relation to Chinese cultural beliefs about depression. Limitations of this preliminary study were acknowledged. Copyright © 2012 Elsevier B.V. All rights reserved.

Anxiety and depression are associated with an activation of coagulation and an impairment of fibrinolysis, which may contribute to the increased cardiovascular risk associated with the two disorders. However, very few studies have examined the impact of psychological distress on coagulation factors in coronary artery disease patients. The aim of this study was to assess the correlation between anxiety/depression and factors of coagulation and fibrinolysis in patients who had suffered an acute MI three months prior. In 148 patients, anxiety and depression were assessed by the Hospital Anxiety and Depression Scale (HADS) shortly after MI and three months later. At the second time of assessment, plasma levels of fibrinogen, factor VII, factor VIII, von Willebrand factor, prothrombin-fragment 1 and 2, tissue-plasminogen-activator, plasminogen activator inhibitor-1, D-dimer, and homocysteine were measured. In 32% of the patients, elevated levels of anxiety and depression were found three months after a MI. Multiple regression analyses showed that coagulation and fibrinolysis markers were not significantly associated with HADS anxiety and depression scores. We found that age, gender, BMI, and smoking status were significant predictors for haemostasis factors. A higher age was associated with a higher coagulability but lower anxiety levels. We measured parameters of coagulation and fibrinolysis in patients three months after MI and found no predictive value of HADS anxiety and depression scores shortly after MI or at the time of blood sampling. The effects of age on the relationship between anxiety and haemostasis should be further investigated. Copyright © 2017 Elsevier Inc. All rights reserved.

Although reducing socioeconomic inequalities in depression is necessary, their associated factors have rarely been studied. This study aimed to screen the potential contextual factors associated with income-based inequality in older adults' depression. Using data from the Japan Gerontological Evaluation Study (JAGES) of 2013, we conducted an ecological study covering 77 communities in Japan. Our measures of socioeconomic inequalities in depression were the slope index of inequalities (SII) and the relative index of inequalities (RII) of the prevalence of depressive symptoms across three income levels. We categorized available community-level factors, including socio-demographic factors, social participation, social relationships, subjective changes in the residential area, and the built environment. These indicators were aggregated from individual responses of 51,962 and 52,958 physically independent men and women, respectively, aged 65 years or more. We performed multiple linear regression analyses to explore factors with statistical significance of a two-tailed P-value less than 0.05. Factors associated with shallower gradients in depression for men included higher participation in local activities and reception or provision of social support, which did not show significant association among women. Perceived increases in unemployment and economic inequalities were positively associated with larger inequalities in both genders (P < 0.05). The built environment did not indicate any significant association. A community environment fostering social activities and relationships might be associated with smaller income-based inequalities in depression. There is a need for more deterministic studies for planning of effective community interventions to address socioeconomic inequalities in depression.

A study conducted as part of the development of the Eleventh International Classification of Mental Disorders for Primary Health Care (ICD-11 PHC) provided an opportunity to test the relationships among depressive, anxious and somatic symptoms in PHC. Primary care physicians participating in the ICD-11 PHC field studies in five countries selected patients who presented with somatic symptoms not explained by known physical pathology by applying a 29-item screening on somatic complaints that were under study for bodily stress disorder. Patients were interviewed using the Clinical Interview Schedule-Revised and assessed using two five-item scales that measure depressive and anxious symptoms. Structural models of anxious-depressive symptoms and somatic complaints were tested using a bi-factor approach. A total of 797 patients completed the study procedures. Two bi-factor models fit the data well: Model 1 had all symptoms loaded on a general factor, along with one of three specific depression, anxiety and somatic factors [x2 (627) = 741.016, p < 0.0011, RMSEA = 0.015, CFI = 0.911, TLI = 0.9]. Model 2 had a general factor and two specific anxious depression and somatic factors [x2 (627) = 663.065, p = 0.1543, RMSEA = 0.008, CFI = 0.954, TLI = 0.948]. These data along with those of previous studies suggest that depressive, anxious and somatic symptoms are largely different presentations of a common latent phenomenon. This study provides support for the ICD-11 PHC conceptualization of mood disturbance, especially anxious depression, as central among patients who present multiple somatic symptoms.

To assess the prevalence rate of depressive symptoms in left-behind participants aged 7-17 years and to explore the associated socio-demographic and communication factors. Participants were 4857 left-behind children and adolescents in Chongqing. They were screened for depressive symptoms using a 27-item Children׳s Depression Inventory (CDI) and social-demographic variables were evaluated with a structured scale. Uncorrected Pearson chi-square test and logistic regression were applied to analyzing the data. The total prevalence rate of depressive symptoms was 24.8%. Significant difference was found in the prevalence rate of depressive symptoms among groups of different income, grade, age, left-behind subtypes, and different frequency, ways and topics of parent-child communication. We found that the risk factors for depression were absence of parents, low frequency of parent-child communication, and communication by letter or about sensitive topics. The grade group 2-3 and age group 16-17 were at a higher risk of depression than all other grade and age subgroups. The protective factors for depression were high-income, high frequency of parent-child communication, communication by telephone or about such topic as learning experience, school life, and feelings. Self-report bias and cross-sectional nature of the sampling are major limitations of this study. The prevalence rate of depressive symptoms among left-behind children and adolescents in Chongqing is much higher than previously reported prevalence in other regions of China. The risk and protective factors for depression among left-behind children and adolescents are worthy of public attention. Copyright © 2015. Published by Elsevier B.V.

To explore potential mediating and moderating factors that influence the association between paternal depression in the postnatal period and subsequent child behavioral and emotional problems. A population-based cohort (N = 13,822) from the Avon Longitudinal Study of Parents and Children (ALSPAC) was recruited during pregnancy. Paternal and maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale at 8 weeks after the birth of the child. Child outcomes were assessed at 3.5 years by using the Rutter revised preschool scales and at 7 years by using the Strengths and Difficulties Questionnaire. Path analysis was used to assess hypothesized mediators (ie, depression in the other parent, couple conflict, and paternal noninvolvement) of the associations between both paternal and maternal depression and child outcomes. We also tested for hypothesized moderators (ie, paternal education and antisocial traits). Family factors (maternal depression and couple conflict) mediated two-thirds of the overall association between paternal depression and child outcomes at 3.5 years. Similar findings were seen when children were 7 years old. In contrast, family factors mediated less than one-quarter of the association between maternal depression and child outcomes. There was no evidence of moderating effects of either parental education or antisocial traits. The majority of the association between depression in fathers postnatally and subsequent child behavior is explained by the mediating role of family environment, whereas the association between depression in mothers and child outcomes appears to be better explained by other factors, perhaps including direct mother-infant interaction.

Background In South Korea, the number of workers suffering from mental illnesses, such as depression, has rapidly increased. There is growing concern about depressive symptoms being associated with both working conditions and psychosocial environmental factors. Objectives To investigate potential psychosocial environmental moderators in the relationship between working conditions and occupational depressive symptoms among wage workers. Methods Data were obtained from the wage worker respondents (n = 4,095) of the Korean National Health and Nutrition Examination Survey of 2009. First, chi-square tests confirmed the differences in working conditions and psychosocial characteristics between depressive and non-depressive groups. Second, multivariate logistic regression analysis was performed to examine the moderating effects of the psychosocial environmental factors between working conditions and depressive symptoms. Results After adjusting for potential covariates, the likelihood of depressive symptomatology was high among respondents who had dangerous jobs and flexible work hours compared to those who had standard jobs and fixed daytime work hours (OR = 1.66 and 1.59, respectively). Regarding psychosocial factors, respondents with high job demands, low job control, and low social support were more likely to have depressive symptoms (OR = 1.26, 1.58 and 1.61, respectively). Conclusions There is a need to develop non-occupational intervention programs, which provide workers with training about workplace depression and improve social support, and the programs should provide time for employees to have active communication. Additionally, companies should provide employees with support to access mental healthcare thereby decreasing the occurrence of workplace depression. PMID:27373792

Depression and intimate partner violence (IPV) are significant health issues for U.S. women. Interaction effects between IPV and other psychosocial factors on the severity of depressive symptoms have not been fully explored. This study assessed effect modification, that is, how IPV interacts with sociodemographics, psychosocial factors and health risk behaviors, on the severity of depressive symptoms in women. We utilized cross-sectional data from female respondents (n = 16,106) of the 2006 Behavioral Risk Factors Surveillance Survey. Sociodemographics, psychosocial variables, and health risk behaviors determined to be significantly associated with depression were tested for interaction effects with IPV. Weighted ordinal logistic regression and predicted probabilities illustrated the effect of IPV status on depressive symptom severity, stratified by interaction effects. Recent and lifetime IPV exposure were associated with more severe depressive symptoms compared with no IPV exposure. IPV history interacted with employment status and social support on the severity of depressive symptoms in women. Overall, any IPV exposure was associated with more severe depressive symptoms among women with low social support and unemployment, although the effect of recent (versus lifetime) IPV was most pronounced among women with high social support or employed women. Social support and employment status interact with IPV on the severity of depressive symptoms in women. Therefore, social support or workplace interventions designed to improve depressive symptoms should examine IPV history. Copyright © 2014 Jacobs Institute of Women's Health.

When developing maternity care services, it is important to know how psychosocial factors affect the course of post-partum depression (PPD), and how depressed mothers are treated. The aim of this study is to assess how adverse childhood experiences, poor present support and violence, and low socioeconomic status (SES) associate with PPD, specifically in new onset and recurrent post-partum depression. The second aim is to assess the treatment received for PPD. This is a cross-sectional study. The study group comprises 104 mothers with a current episode of PPD, and a control group of 104 mothers without an episode. The Structured Clinical Interview for DSM-IV Axis I Disorders was used for data collection. Psychosocial risk factors, treatment issues, and the course of depression were assessed with a structured self-report questionnaire. In age-adjusted multivariate analyses, adverse childhood experiences, a low level of present support in close relationships, and a poor SES were associated significantly with PPD. Childhood adversity was associated with both new onset and recurrent depression. Nevertheless, a low level of support and a poor SES were also associated with recurrent depression. A quarter of mothers with a major depressive episode in the post-partum period attended psychiatric services. In mothers with new onset depression, the proportion was only 5%. There is an urgent need to develop the diagnostics of depression in maternity care services. An awareness of psychosocial risk factors might help in this. More depressed mothers should be referred to psychiatric services.

Objective To determine if independent candidate genes can be grouped into meaningful biological factors and if these factors are associated with the diagnosis of chronic fatigue syndrome (CFS) and fibromyalgia (FMS) while controlling for co-morbid depression, sex, and age. Methods We included leukocyte mRNA gene expression from a total of 261 individuals including healthy controls (n=61), patients with FMS only (n=15), CFS only (n=33), co-morbid CFS and FMS (n=79), and medication-resistant (n=42) or medication-responsive (n=31) depression. We used Exploratory Factor Analysis (EFA) on 34 candidate genes to determine factor scores and regression analysis to examine if these factors were associated with specific diagnoses. Results EFA resulted in four independent factors with minimal overlap of genes between factors explaining 51% of the variance. We labeled these factors by function as: 1) Purinergic and cellular modulators; 2) Neuronal growth and immune function; 3) Nociception and stress mediators; 4) Energy and mitochondrial function. Regression analysis predicting these biological factors using FMS, CFS, depression severity, age, and sex revealed that greater expression in Factors 1 and 3 was positively associated with CFS and negatively associated with depression severity (QIDS score), but not associated with FMS. Conclusion Expression of candidate genes can be grouped into meaningful clusters, and CFS and depression are associated with the same 2 clusters but in opposite directions when controlling for co-morbid FMS. Given high co-morbid disease and interrelationships between biomarkers, EFA may help determine patient subgroups in this population based on gene expression. PMID:26097208

The aim of this study is to examine the effects of personality (temperament and character) on specific depression and specific anxiety. A total of 541 Japanese undergraduates were investigated by using the Temperament and Character Inventory (TCI) and the Hospital Anxiety and Depression (HAD) scale. Hierarchical multiple regression analyses demonstrated that specific depression was predicted by lower Reward-Dependence, Persistence, Self-Directedness, Cooperativeness, and Self-Transcendence; specific anxiety was predicted by higher Novelty-Seeking, Harm-Avoidance, Persistence, and Self-Transcendence, and lower Self-Directedness. Immaturity of Self-Directedness is a risk factor for negative affectivity. Immaturity of all character dimensions is a risk factor for specific depression. The relationship between Harm-Avoidance and depression in previous studies may be linked partly to somatic symptoms that were deliberately eliminated in the HAD scale.

The results of many studies and recent meta-analyses strongly suggest that depression is a risk factor for total and cardiovascular mortality, both in the general population and in patients with known heart disease. By contrast, the association between depression and sudden death or cardiac arrest has received little attention. This issue has been investigated in three recent studies; two were carried out in the general population and showed depression to be a independent risk factor for sudden death. The other study was carried out in patients with acute myocardial infarction (AMI); the adjusted relative risk (RR) of sudden death was significantly increased in depressed patients but, after adjustment for dyspnea/fatigue (a common symptom for heart disease and depression), the RR was no longer statistically significant. However, when the cognitive-affective depressive symptoms were examined separately from the somatic ones (dyspnea/fatigue, etc.), there was a clear trend for an association between cognitive-affective symptoms and sudden death. Because a risk factor can be defined as 'independent' only in a multivariate analysis in which variables are dichotomized, the presence of common symptoms between heart disease and depression represents a very difficult problem. However, taken together, the results of studies carried out in the general population and in patients with AMI strongly suggest that depression is a significant risk factor for sudden death.

Lifetime prevalence rates for any psychological disorder are higher than previously thought. Depression in the workplace may lower work productivity and increase maladjustment in daily professional life. The study aimed to investigate the prevalence of depression symptoms and the work-related risk factors in Egyptian working women. A cross-sectional study was carried out on 600 working women in family health facilities in Tala district, Menoufia governorate in 2015. Two questionnaires were used: one of them was an Arabic translated form of the questionnaire found in the Egyptian Practice Guidelines established by the Ministry of Health and population for family physicians to use in assessing the prevalence of depression symptoms. The second one was a predesigned questionnaire used to assess risk factors concerning demographic characteristics and the work environment related to depression symptoms. The prevalence rate of depression symptoms among working women was 37.5%. Multiple logistic regression analyses reveal that the following work-related factors were associated with an increased likelihood of exhibiting positive depression symptoms: work-related activities continued during home time, such as telephone calls or messages [odds ratio (OR)=5.10; 95% confidence interval (CI): 1.69-15.39], when work problems affect concentration and interactions with family (OR=148.67; 95% CI: 50.04-441.71), and difficulty with household chores (OR=6.63; 95% CI: 1.64-26.73). In addition, the following sociodemographic factors were significant: being divorced or widowed (OR=4.10; 95% CI: 2.28-7.36), no enough income (OR=2.59; 95% CI: 1.68-3.97), and rural residence (OR=1.74; 95% CI: 1.08-2.78). Reported depression symptoms were high among working women in Menoufia. Both unfavorable employment conditions and background characteristics such as being divorced/widow, low income, and rural residence were factors determining depression symptoms. It is necessary to establish preventive strategies for female workers to control the negative effect of depression in the workplace.

Depression is among the 10 major causes of disability in Mexico. Yet, local contextual factors associated to the disorder remain poorly understood. We measured the impact of several factors on severe depression such as demographics, pharmacotherapy, multimorbidity, and unhealthy behaviors in Mexican teachers. A total of 43,845 Mexican female teachers from 12 Mexican states answered the Patient Health Questionnaire (PHQ9). Data were part the Mexican Teacher's Cohort prospective study, the largest ongoing cohort study in Latin America. Unadjusted and adjusted estimates assessed the impact of several contextual factors between severe versus mild-no depression cases. In total 7026 teachers (16%) had a PHQ9 score compatible with severe depression. From them, only 17% received psychotropics, compared to 60% for those with a formal diagnosis. Less than 5% of teachers with PHQ9 scores compatible with severe depression had a formal diagnosis. Adjusted analysis reported higher odds of pharmacotherapy, having ≥ 3 comorbidities, higher levels of couple, family and work stress, fewer hours of vigorous physical activity, higher alcohol consumption, and smoking as risk factors for severe depression. Also, rural residents of northern and center states appeared more severely depressed compared to their urban counterparts. On average, the PHQ9 scores differed by ~ 10 points between severe and mild-no depressed teachers. A cross-sectional design. Also, the study focused on female teachers between ages 25 and 74 years old, reducing the generalizability of the estimates. Under-diagnosis of clinical depression in Mexican teachers is concerning. Unhealthy behavior is associated with severe depression. The information collected in this study represents an opportunity to build prevention mechanisms of depression in high-risk subgroups of female educators and warrants improving access to mental care in Mexico.

Maternal depression is a major public health problem in low- and middle-income countries including India. Very few studies have assessed association of various risk factors with antenatal depression in rural Indian women, especially the effect of marital conflict, gender disadvantage and gender preference on antenatal depression. This paper describes the prevalence of probable antenatal depression in rural Maharashtra, a state in the western part of India and specifically assesses the association of marital and gender disadvantage factors and gender preference for a male child with antenatal depression. Primary Health Centre-based cross-sectional survey of antenatal women in rural Maharashtra was carried out. The outcome of interest was a probable diagnosis of depression in antenatal women which was measured using the Edinburgh postnatal depression scale (EPDS). Data were analyzed using simple and multiple logistic regression. 302 women in their antenatal period were included in this study. The outcome of antenatal depression (EPDS > 12) was found in 51 women (16.9%, 95% CI 12.6-21.1%). Feeling pressurized to deliver a male child was strongly associated with the outcome of antenatal depression (adjusted odds ratio (OR): 3.0; 95% CI 1.4-6.5). Unsatisfactory reaction of in-laws to dowry (adjusted OR 11.2; 95% CI 2.4-52.9) and difficult relationship with in-laws (adjusted OR 5.3; 95% CI 2.4-11.6) were also significantly associated with antenatal depression. Our findings demonstrate that antenatal depression in rural women of Western Maharashtra is associated with gender disadvantage factors, especially related to preference for a male child. The agenda to improve maternal mental health should be ultimately linked to address the broader social development goals and gender empowerment.

The aims of the current study were to evaluate geriatric depression and its risk factors in advanced cancer patients. A cross-sectional study was carried out in a palliative care unit in Greece. Patients completed the Geriatric Depression Scale, the M. D. Anderson Symptoms Instrument (MDASI), the Activities of Daily Living and the Mini-Mental State Examination. Patients were included if they were aged >65 years, if they had cancer, were able to communicate and had agreed to sign informed consent. The final sample consisted of 92 elderly advanced cancer patients. The prevalence of depression was found to be 67.4%. The univariate comparison between the depressed elderly and non-depressed group showed that patients with metastases were found to be 2.2-fold more likely to suffer from geriatric depression compared with those without metastases (P = 0.074). Patients with moderate or severe cognitive impairment were found to be 3.61-fold more likely to suffer from geriatric depression in comparison with those with normal cognitive function (P = 0.019). In the multiple logistic regression analysis, elderly with cognitive impairment were 3.3-fold more likely to have geriatric depression than those without (adjusted odds ratio = 3.3 [95% CI 0.99-10.74], P = 0.052) and MDASI factor 1 was consistently a significant risk factor for depression in the elderly; when MDASI factor 1 increased by 1 unit, the odds of being classified as depressed increased by 7.6%. The present study found that cognitive impairment and symptoms such as enjoyment of life, walking, relationship with people, general activity, sadness and pain (MDASI F1) are strong independent predictors of depression in the elderly. © 2012 Japan Geriatrics Society.

Clinical and epidemiological studies have shown an association between anxiety and depression and pain in the back and neck. The nature of this relationship is not clear. This study aimed to investigate the extent to which common genetic and environmental aetiological factors contribute to the covariance between symptoms of anxiety and depression and back-neck pain. Measures of back-neck pain and symptoms of anxiety and depression were part of a self-report questionnaire sent in 1992 to twins born in Norway between 1967 and 1974 (3996 pairs). Structural equation modelling was applied to determine to what extent back-neck pain and symptoms of anxiety and depression share genetic and environmental liability factors. The phenotypic correlation between symptoms of anxiety and depression and back-neck pain was 0.31. Individual differences in both anxiety and depression and back-neck pain were best accounted for by additive genetic and individual environmental factors. Heritability estimates were 0.53 and 0.30 respectively. For back-neck pain, however, a model specifying only shared- and individual environmental effects could not be rejected. Bivariate analyses revealed that the correlation between back-neck pain and symptoms of anxiety and depression was best explained by additive genetic and individual environmental factors. Genetic factors affecting both phenotypes accounted for 60% of the covariation. There were no significant sex differences. The results support previous findings of a moderate association between back-neck pain and symptoms of anxiety and depression, and suggest that this association is primarily due to common genetic effects.

Objective Few studies have examined the effect of risk factor modifications on depression incidence. This study was to explore psychosocial risk factors for depression and quantify the effect of risk factor modifications on depression incidence in a large-scale, longitudinal population-based study. Methods Data were from the Montreal Longitudinal Catchment Area study (N=2433). Multivariate modified Poisson regression was used to estimate relative risk (RR). Population attributable fractions were also used to estimate the potential impact of risk factor modifications on depression incidence. Results The cumulative incidence rate of major depressive disorder at the 2-year follow-up was 4.8%, and 6.6% at the 4-year follow-up. Being a younger adult, female, widowed, separated or divorced, Caucasian, poor, occasional drinker, having a family history of mental health problems, having less education and living in areas with higher unemployment rates and higher proportions of visible minorities, more cultural community centres and community organisations, were consistently associated with the increased risk of incident major depressive disorder. Although only 5.1% of the disease incidence was potentially attributable to occasional drinking (vs abstainers) at the 2-year follow-up, the attribution of occasional drinking doubled at the 4-year follow-up. A 10% reduction in the prevalence of occasional drinking in this population could potentially prevent half of incident cases. Conclusions Modifiable risk factors, both individual and societal, could be the targets for public depression prevention programmes. These programmes should also be gender-specific, as different risk factors have been identified for men and women. Public health preventions at individual levels could focus on the better management of occasional drinking, as it explained around 5%~10% of incident major depressive disorders. Neighbourhood characteristics could also be the target for public prevention programmes. However, this could be very challenging. A cost-effectiveness analysis of a variety of prevention efforts is warranted. PMID:28601831

The depression is a principal problem of public health. The principal aim of this study is to determine the role of the social groups as factor protective in elderly, to evaluate the agreement by American Psychiatric Association Criterions and Hamilton Depression test, and also to determine other socio-cultural risk factors associated with depressive syndrome in elderly. Cross-sectional survey. The sample consisted of 602 elderly people (eligible subjects) were men (223) and women (379) between 60 and 94 years (males and females), residents in the south-west of Barranquilla, Colombia. A previously tested, self answer questionnaire was used, therefore, we needed a report consent. Risk measures: Odds Ratio (OR-95% Confidence intervalue), Kappa test to agreement by the nine criteria of the American Psychiatric Association and Hamilton test so, screening testing. The participation in social groups was a protector factor. (Odds Ratio = 0.5; 95% CI 0.34-0.73, p = 0.001). The rate 29.9% was obtained with prevalence of depression in elderly (21.4%-39.4%) affecting principally males (32.7%). The agreement by Kappa test = 0.63 was very important or good. Sensibility = 56.1% (48.5%-63.4%) Specificity = 0.93% (97.8%-99.8%) and Predictive Positive Value = 97.1% (91.2%-99.3%). This survey was to determine risk factors related to depression in elderly in anyway can be potentially modifiable. The familiar disfunction by moderate and serious, the lack as blindness and deafness, the loneliness, the housingness and low incomes were obtained with risk factors associated to depression. The participation in a social group is a protective factor to depression syndrome in elders. The nine criteria of the American Psychiatric Association to allow the depressed patient exactly as sick even though is not necessary to screening because this test is low sensibility for used in a population elderly.

Limited data exists on the association of war trauma with comorbid posttraumatic stress disorder (PTSD)-depression in the general population of low-income countries. The present study aimed to evaluate socioeconomic and trauma-related risk factors associated with PTSD, depression, and PTSD-depression comorbidity in the population of Greater Bahr el Ghazal States, South Sudan. In this cross-sectional community study (n=1200) we applied the Harvard Trauma Questionnaire (HTQ) and MINI International Neuropsychiatric Interview (MINI) to investigate the prevalence of PTSD, depression, and PTSD-depression comorbidity. Multinomial logistic regression analyses were conducted to examine the association between these disorders, previous trauma exposure, sociodemographic, and socioeconomic factors. PTSD only was found in 331 (28%) and depression only in 75 (6.4%) of the study population. One hundred and twelve (9.5%) of the participants had PTSD-depression comorbid diagnosis. Exposure to traumatic events and socioeconomic disadvantage were significantly associated with having PTSD or PTSD-depression comorbidity but not with depression. Participants with a comorbid condition were more likely to be socioeconomic disadvantaged, have experienced more traumatic events, and showed higher level of psychological distress than participants with PTSD or depression alone. In individuals exposed to war trauma, attention should be given to those who may fulfill criteria for a diagnosis of both PTSD and depression.

The first part investigated socio-demographic, cultural and other possible risk factors, including gender preference. The second part comprised the Edinburgh Postnatal Depression Scale (EPDS). EPDS score greater than or equal to 12 indicating probable depression. the prevalence of depression was 30.7% (92/300, 95% confidence interval 25.4-35.9%). Maternal male gender preference was not common and was not associated with antenatal depression. Family male gender preference, unplanned pregnancy, a history of depression and feeling anxious in pregnancy were independently associated with an increased likelihood of depression, whilst support from family and friends, being satisfied with pregnancy and being multiparous were associated with a reduced likelihood of depression. rates of antenatal depression were very high in Asian women with some associated risk factors. However, male gender preference was not associated with antenatal depression. given the high prevalence, screening Asian women for depression may be indicated to allow treatment.

To investigate the association between anxiety-depression and 5-HTTLPR gene polymorphism in school-aged twins. A total of 147 pairs of twins (47 pairs of monozygotic twins, 100 pairs of dizygotic twins) aged 8-12 years from Baotou and Hohhot were selected as respondents. The Achenbach Child Behavior Checklist (CBCL) was used to calculate the scores of anxiety-depression factors in school-aged twins. The DNA was extracted from oral epithelial cells, and polymerase chain reaction was applied for 5-HTTLPR genotyping. The generalized estimating equation (GEE) was used to analyze the effect of 5-HTTLPR polymorphism and family environment on anxiety-depression in school-aged twins. The children with LS and SS genotypes had significantly higher scores of anxiety-depression factors than those with LL genotype (χ2=3.938, P<0.05). The interaction of 5-HTTLPR genotype with family cohesion and family rearing patterns had a significant impact on the scores of anxiety-depression factors in twins (χ2=6.129 and 7.665, both P<0.05). 5-HTTLPR genotype is significantly correlated with the scores of anxiety-depression factors in school-aged twins. In the family with high cohesion and an autocratic family rearing pattern, S allele may increase the possibility of anxiety-depression in twin children.

Prevalence and risk factors of depressive symptoms in a Canadian palliative home care population: a cross-sectional study

PubMed Central

2014-01-01

Background Depression in palliative care patients is important because of its intrinsic burden and association with elevated physical symptoms, reduced immunity and increased mortality risk. Identifying risk factors associated with depression can enable clinicians to more readily diagnose it, which is important since depression is treatable. The purpose of this cross-sectional study was to determine the prevalence of depressive symptoms and risk factors associated with them in a large sample of palliative home care patients. Methods The data come from interRAI Palliative Care assessments completed between 2006 and 2012. The sample (n = 5144) consists of adults residing in Ontario (Canada), receiving home care services, classified as palliative, and not experiencing significant cognitive impairment. Logistic regression identified the risk factors associated with depressive symptoms. The dependent variable was the Depression Rating Scale (DRS) and the independent variables were functional indicators from the interRAI assessment and other variables identified in the literature. We examined the results of the complete case and multiple imputation analyses, and found them to be similar. Results The prevalence of depressive symptoms was 9.8%. The risk factors associated with depressive symptoms were (pooled estimates, multiple imputation): low life satisfaction (OR = 3.01 [CI = 2.37-3.82]), severe and moderate sleep disorders (2.56 [2.05-3.19] and 1.56 [1.18-2.06]), health instability (2.12 [1.42-3.18]), caregiver distress 2.01 [1.62-2.51]), daily pain (1.73 [1.35-2.22]), cognitive impairment (1.45 [1.13-1.87]), being female (1.37 [1.11-1.68]), and gastrointestinal symptoms (1.27 [1.03-1.55]). Life satisfaction mediated the effect of prognostic awareness on depressive symptoms. Conclusions The prevalence of depressive symptoms in our study was close to the median of 10-20% reported in the palliative care literature, suggesting they are present but by no means inevitable in palliative patients. Most of the factors associated with depressive symptoms in our study are amenable to clinical intervention and often targeted in palliative care programs. Designing interventions to address them can be challenging, however, requiring careful attention to patient preferences, the spectrum of comorbid conditions they face, and their social supports. Life satisfaction was one of the strongest factors associated with depressive symptoms in our study, and is likely to be among the most challenging to address. PMID:24636452

Background: Several common factors have been identified for smoking and depression. The The present study explores the relation of psychological and familial factors with depression, by student smoking behavior. Materials and Methods: A total of 5500 middle- and high-school students were selected in Isfahan province in 2010. A self-administered questionnaire collected data on background characteristics, smoking status, depression, and risk factors. Univariate analysis multiple logistic regressions were conducted to compare between depressed and nondepressed people by adolescent smoking status. Odds ratios and the corresponding 95% confidence intervals (CIs) were reported. Results: Fathers lower education attainment was accompanied adolescents higher depression prevalence. Parental smoking and sibling smoking increased the depression likelihood by 1.41 (95% CI: 1.18, 1.68) and 1.43 folds (95% CI: 1.04–1.94) for never-smokers. Positive attitude toward smoking increased the probability of depression by 1.18 among never-smokers. Never-smokers lacking refusal skill had 1.23 (1.03–1.47) higher chance of depression. A higher level of self-efficacy related to lower chance of depression. Taking risky behavior, increased the depression likelihood by 1.56 (95% CI: 1.29–1.89) in never-smokers, by 1.85 (95% CI: 1.37–2.44) in experimental smokers, and by 1.14 times (95% CI: 1.01–1.72) in current smokers. Family conflict increased depression chance by 2.25 times (95% CI: 1.89–2.66) in never-smokers, by 1.95 (95% CI: 1.46–2.61) in experimental smokers, and by 2.06 times (95% CI: 1.38–3.08) in current smokers. Conclusions: Targeting self-efficacy level, risky behavior, and family conflict can drop the comorbidity of smoking and depression simultaneously. This may help public health practitioners and policymakers to develop common strategies in reducing adolescents smoking and depression comorbidity. PMID:28217648

To investigate the association between male factor infertility and openness to discussing assisted reproductive technology (ART) treatment with levels of depression among men undergoing infertility treatment. Cross-sectional. Not applicable. Three hundred forty participants (170 men and their partners) undergoing ART treatments. Administration of a set of questionnaires. Depressive symptoms were detected by means of the Zung Depression Self-Rating Scale. Participants' willingness to share their infertility treatment experience with other people was assessed by means of self-report questionnaires. In this study, 51.8% of males chose not to discuss their ART treatments with people other than their partner. In addition, the decision to discuss or not discuss the ART treatments with others was significantly associated with men's depressive symptoms. Male factor infertility was significantly associated with depression when considered together with the decision not to discuss ART treatments with others. A general disposition characterized by a lack of openness with others seemed to be a significant predictor of depression. There is a need for routine fertility care to pay greater attention to men's emotional needs. Before commencing reproductive treatment, male patients may benefit from undergoing routine screening for variables (i.e., male factor infertility and openness to others about ART) that may affect their risk of depression.

To identify factors that predict or are correlated with symptoms of depression and anxiety in 10-year-olds. Women and their offspring were followed from the fourth prenatal month through 10 years. There were 636 mother-child pairs at 10 years, a follow-up rate of 83% of the birth cohort. Cognitive, psychological, sociodemographic, and environmental factors were measured at each phase. High depression and anxiety were defined as having a number of symptoms >1 SD above the mean for each measure. These measures were combined to represent high depression and/or anxiety (D/A) at 10 years of age. Predictors from the prenatal period of D/A at 10 years were more maternal depression symptoms, African American race, less social support, greater household density, and prenatal marijuana exposure. From 18 months through 6 years, lower child IQ, child injuries at age 3, and attention problems predicted symptoms of D/A at age 10. Across all study phases, lower child IQ, household density during pregnancy, attention problems, early childhood injuries, and prenatal marijuana exposure predicted D/A. Maternal psychological and sociodemographic factors were not significant in the final model. Factors from gestation and early childhood predict high symptom levels of depression and anxiety at age 10. When gestational exposure, early environmental factors, and child characteristics were considered, maternal depression and socioeconomic status were not significantly associated with early onset D/A. Marijuana exposure during gestation marginally predicted depression/anxiety at age 10.

The emerging dimensional approach to classification and treatment of psychiatric disorders calls for better understanding of diagnosis-related variations in psychiatric syndromes and for proper validation of psychometric scales used for the evaluation of those syndromes. This study tested the hypothesis that negative and depressive syndromes as measured by the Positive and Negative Syndrome Scale (PANSS) are consistent across different diagnoses. We administered the PANSS to subjects with schizophrenia (n = 305), organic brain disease (OBD, n = 66) and major depressive disorder (MDD, n = 75). Confirmatory factor analysis (CFA) was used to establish if the PANSS items for negative symptoms and for depression fit the hypothesized factor structure and if the item factor loadings were similar among the diagnostic groups. The negative and depressive symptom subscales fit well according to a variety of fit indexes for all groups individually after some modest model modification. However, multisample modeling procedures indicated that the pattern of factor loadings was significantly different among the groups in most cases. The results of this study indicate diagnosis-related variations in the negative and depressive syndrome dimensions in schizophrenia, OBD and MDD. These results also validate limited use of the PANSS for evaluation of negative and depressive syndromes in disorders other than schizophrenia. Larger studies are warranted to further evaluate clinical and nosologic significance of diagnostic categories, dimensions and structures of psychiatric syndromes. 2009 S. Karger AG, Basel.

Parkinson's disease is associated with high rates of depression. There is growing interest in non-pharmacological management including psychological approaches such as Cognitive Behaviour Therapy. To date, little research has investigated whether processes that underpin cognitive models of depression, on which such treatment is based, apply in patients with Parkinson's disease. The study aimed to investigate the contribution of core psychological factors to the presence and degree of depressive symptoms. 104 participants completed questionnaires measuring mood, motor disability and core psychological variables, including maladaptive assumptions, rumination, cognitive-behavioural avoidance, illness representations and cognitive-behavioural responses to symptoms. Regression analyses revealed that a small number of psychological factors accounted for the majority of depression variance, over and above that explained by overall disability. Participants reporting high levels of rumination, avoidance and symptom focusing experienced more severe depressive symptoms. In contrast, pervasive negative dysfunctional beliefs did not independently contribute to depression variance. Specific cognitive (rumination and symptom focusing) and behavioural (avoidance) processes may be key psychological markers of depression in Parkinson's disease and therefore offer important targets for tailored psychological interventions.

Enache, Daniela; Winblad, Bengt; Aarsland, Dag

Depression in people with dementia has important implications, such as reduced quality of life of patients and carers, and is associated with increased costs and reduced cognition. Here, we review recent studies of the epidemiology, course, mechanisms and treatment of depression in people with dementia. Depression is both a risk factor and a prodrome of Alzheimer's disease. Depression is a common occurrence in all types of dementias and at all disease stages, including in mild cognitive impairment (MCI). Many studies have explored whether depression in MCI increased the conversion rate to dementia, but findings are inconsistent. Studies of the mechanisms are relatively few and findings inconsistent, but inflammatory, trophic and cerebrovascular factors may contribute, in addition to monoamine deficiency and severity of plaques and tangle pathology. Studies of antidepressants for depression in dementia are inconclusive, with several negative findings reported in recent large studies, suggesting that antidepressant may not confer benefit over placebo. Depression is a common risk factor, prodrome, and accompanying symptom of people with Alzheimer's dementia. The mechanisms are unknown, and there is little evidence of effective therapies.

Parent depressive symptomatology moderates the etiology of externalizing behavior in childhood: An examination of gene-environment interaction effects.

PubMed

Clark, D Angus; Klump, Kelly L; Burt, S Alexandra

2018-04-26

Parent depressive symptomatology is robust risk factor for externalizing behavior in childhood (Goodman et al., 2011). Although the precise mechanisms underlying this association have yet to be fully illuminated, there is some evidence that parent depression can impact externalizing behavior via both genetic and environmental pathways. In the current study, we investigated the extent to which genetic and environmental influences on externalizing behavior are moderated by parent depressive symptoms (i.e., genotype-environment interaction) in a sample of 2,060, 6- to 11-year-old twins. Results suggest that genetic influences explain more variance in externalizing behavior as maternal depressive symptoms increase, whereas shared environmental effects decrease. These findings were specific to maternal depressive symptoms, however, and did not extend to not paternal depressive symptoms. Findings are critical for understanding the role of parental depression as a risk factor for problematic child behavior, and informing programs that seek to minimize the impact of this risk factor.

The purpose of this study was to identify subgroups of university students with the highest likelihood of remaining at elevated levels of depressive symptoms six months following the receipt of a depressive prevention intervention on the basis of known risk factors and participation in one of two depression prevention programs. Data from a randomized controlled trial evaluating depression prevention among 133 college students with elevated depressive symptoms were analyzed. Participants were randomized to a cognitive-behavioral or relaxation training group preventive intervention. Classification tree analysis showed that older age was the strongest risk factor for persistently elevated depression. Additional risk factors were: (1) for younger students, fewer daily pleasant activities; (2) for those with higher level of pleasant activities, higher level of stressful events; and (3) for those with higher level of stressful events, lower assertiveness. Results offer directions for prevention foci, identify specific subgroups of college students to target for depression prevention efforts, and suggest that research aim to help older, non-traditional students or graduating students manage the transition from college to the work force.

To identify factors associated with anxiety and depression of patients with implantable cardioverter defibrillators. Implantable cardioverter defibrillator is effective to increase survival from life-threatening arrhythmias, but it lowers health-related quality of life. Anxiety and depression had significant negative association with health-related quality of life. However, knowledge about factors associated with these two negative emotions in this specific population is inadequate. A cross-sectional descriptive design was conducted. Secondary analysis was performed to address the aim. A convenience sampling of patients with implantable cardioverter defibrillators was performed. Anxiety and depression were measured by the Hospital Anxiety and Depression Scale through face-to-face interview. Stepwise multivariable regression results showed that older age (aged 60-69 and ≥70: B = 2·08 and 3·31, p = 0·039 and <0·001), self-care dependence (B = 3·47, p < 0·001), being married (B = -2·21, p = 0·004) and having ischaemic heart disease (B = -1·80, p = 0·008) were significantly associated with depression. However, there was no significant factor associated with anxiety. Factors associated with depression among patients with implantable cardioverter defibrillator are identified. Older age (aged ≥60) and more self-care dependence have positive, but being married and having ischaemic heart disease have negative association with depression. Strategies to reduce psychological distress are highlighted. The study findings direct the care to improve health-related quality of life by reducing and controlling vulnerabilities arising from depression. Patients who are older people (≥aged 60) and more self-care dependent perceive higher depression. Nursing strategies are suggested to reduce depression especially for those who are older people and more self-care dependent. Early screening is essential to provide immediate care for reducing vulnerabilities arising from depression. Performing comprehensive assessment for self-care ability and providing adequate assistance are crucial. Family involvement may reduce depression through providing physical and psychosocial support. © 2016 John Wiley & Sons Ltd.

Doctors, the major workforce in hospitals, are doing heavy emotional and physical work which may lead to depressive symptoms. However, in China, few studies are available pertaining to the prevalence and associated factors of depressive symptoms among doctors. The aim of this study was to evaluate the prevalence of depressive symptoms and to explore its associated factors among Chinese doctors in public hospitals. This cross-sectional study was performed during the period of September/October 2008. The study population comprised of 1,890 doctors registered and working in the 20 national hospitals in Liaoning province, northeast of China. A questionnaire that comprised depressive symptoms assessed by the Chinese Version of the Center for Epidemiologic Studies Depression Scale (CES-D), demographic factors, work conditions, occupational stress, and coping strategies was distributed to these doctors. A total of 1,488 effective respondents became our subjects (effective response rate 78.7%). Multivariate logistic regression was used to explore the factors related to depressive symptoms. The prevalence of depressive symptoms among doctors was 65.3%. Multivariate logistic analyses showed that high role insufficiency (OR 2.15, 95% CI 1.66-2.78), worse doctor-patient relationship (OR 2.07, 95% CI 1.62-2.64), having a chronic disease (OR 1.73, 95% CI 1.31-2.27), serious role boundary (OR 1.54, 95% CI 1.21-2.00), and role overload (OR 1.42, 95% CI 1.11-1.81) were positively associated with depressive symptoms; whereas adequate rational coping (OR 0.58, 95% CI 0.45-0.76) and social support (OR 0.75, 95% CI 0.57-0.98) were negatively associated with depressive symptoms. Most Chinese doctors probably have depressive symptoms. Role insufficiency, doctor-patient relationship, and rational coping seemed to be crucial in relation to depressive symptoms. Efficient interventions such as taking further education course, improving communications with patients, and improving the ability of rational coping should be considered by health administrators aiming at improving the quality of Chinese doctors' mental health from the view point of depressive symptoms.

Depression in cancer patients. An approach to differential diagnosis and treatment.

Despite recent attention to death and dying, many questions remain about the diagnosis and treatment of depression in cancer patients. To provide a framework for effective treatment, this article distinguishes the following types of depression: (1) transient stress reactions, (2) major psychiatric disturbances requiring prompt attention, and (3) other depressive reactions. Depressions in the third general category, comprising the majority, are often mismanaged because of characterological, interpersonal, and organic factors receive insufficient attention. Understanding of such factors provides a basis for rational intervention with both patients and their families.

Purpose Depressive symptoms during adolescence are positively associated with peer-related beliefs, perceptions, and experiences that are known risk factors for substance misuse. These same risk factors are targeted by many universal substance misuse prevention programs. This study examined whether a multicomponent universal substance misuse intervention for middle schoolers reduced the associations between depressive symptoms, these risk factors, and substance misuse. Methods The study used data from a place-randomized trial of the PROSPER (PROmoting School-Community-University Partnerships to Enhance Resilience) model for delivery of evidence-based substance misuse programs for middle schoolers. Three-level within-person regression models were applied to four waves of survey and social network data from 636 adolescents followed from 6th through 9th grades. Results When adolescents in control school districts had more symptoms of depression, they believed more strongly that substance use had social benefits, perceived higher levels of substance misuse among their peers and friends, and had more friends who misused substances, although they were not more likely to use substances themselves. Many of the positive associations of depressive symptoms with peer-related risk factors were significantly weaker or not present among adolescents in intervention school districts. Conclusions The PROSPER interventions reduced the positive associations of adolescent symptoms of depression with peer-related risk factors for substance misuse. PMID:27751712

This study aims to investigate the role of personality traits and subjective exposure experiences in posttraumatic stress disorder and depression symptoms. In Qingchuan, 21,652 children aged 7 to 15 years were assessed using face-to-face interviews one year after the Wenchuan earthquake in China. The Junior Eysenck Personality Questionnaire, a modified earthquake exposure scale, the UCLA Posttraumatic Stress Disorder Reaction Index (adolescent), and the Adolescent Depression Inventory were used to assess personality characteristics, trauma experiences, posttraumatic stress disorder and depression symptoms, respectively. The measurement was completed with 20,749 children. After adjusting for other factors by multinomial logistic regression analysis, neuroticism, having felt unable to escape from the disaster and having been trapped for a longer time were risk factors of posttraumatic stress disorder and depression symptoms. Socialization was a protective factor of them. Having felt extreme panic or fear was a risk factor of posttraumatic stress disorder symptoms. For depression symptoms, introversion and psychoticism were risk factors, and extraversion was a protective factor. This study was conducted with the largest representative sample of child survivors of a natural, devastating disaster in a developing country. These results could be useful for planning psychological intervention strategies for children and for influencing further research.

The Hospital Anxiety and Depression Scale (HADS) is a common screening instrument used to determine the levels of anxiety and depression experienced by a patient and has been extensively used in patients with coronary artery disease (CAD). This study aimed to establish the factor structure of HADS in a Malaysian sample of 189 patients with CAD. Factor analysis of HADS using principal component analysis with varimax rotation yielded 3 factors. Confirmatory factor analysis supported the use of HADS in assessing 3 distinct dimensions of psychological distress--namely, anxiety, anhedonia, and psychomotor retardation. The HADS showed good internal consistency and was found to be a valid measure of psychological distress among Malaysian patients with CAD. However, low mean scores on the original 2 factors--that is, anxiety and depression--and also on the 2 depression subscales--anhedonia and psychomotor retardation--suggests that the recommended cutoff score to screen for psychological distress among CAD patients be reevaluated. Further research to determine the generalizability and consistency for the tridimensional structure of the HADS in Malaysia is recommended. © 2014 APJPH.

Abstract Background: Depression and anxiety are common concerns for hospice caregivers. Objective: This study looked at the prevalence and variables associated with hospice caregiver depression and anxiety, as well as the relationship between the two conditions. Subjects: We did a secondary analysis of preexisting data. Measurements: Measures included the PHQ-9 and GAD-7. Results: Nearly one-quarter of caregivers were moderately to severely depressed, and nearly one-third reported moderate to severe symptoms of anxiety. Risk factors for both depression and anxiety included younger age and poorer self-rated global health. Depression-specific risk factors included being married and caring for a patient with a diagnosis other than cancer. The sole anxiety-specific risk factor identified was geographic location, as caregivers living in the Southeast were found to have greater anxiety than those in the Midwest. Conclusion: Hospice providers' recognition of family caregivers as both coproviders and corecipients of care underscores the need to more fully assess and respond to depression and anxiety among caregivers.

This study examined the impact of discrimination and legal acculturative stress on Major Depression Episode lifetime among Asian American immigrants. It further examined the role of immigration related-factors (age at immigration, reason for immigration, and years spent in the U.S.) on the relationship of acculturative stress and Major Depression Episode lifetime. The National Latino and Asian American Study 2002-2003 dataset was used. The study findings were: (1) high discrimination and legal acculturative stress were associated with Major Depression Episode lifetime; (2) age at immigration buffered the relationship of discrimination acculturative stress and Major Depression Episode lifetime as well as the relationship of legal acculturative stress and Major Depression Episode lifetime; and (3) years spent in the U.S. buffered the relationship of discrimination acculturative stress and Major Depression Episode lifetime only. These findings highlight the complex relationship of factors that impact the mental health of the Asian American immigrants.

Depression is the most common mood and psychiatric disorder. The aim of this comprehensive study was to provide a complete picture of the prevalence and risk factors of depression. The study employed a systematic review methodology, searching Iranian and international databases. After screening and evaluating the articles, a synthesis of 53 articles was accumulated. A meta-analysis of the studies showed that the prevalence of children and adolescent depression was 43.55% using the BDI, 15.87 % using SCL-90, and 13.05% using CDI. Also, the prevalence of depression was higher among girls than boys based on the BDI and CDI results. The most important factors contributing to depression were: the female sex, poor inter-parental relationship, poor adolescent-parent relationship, low socio-economic status (SES), state of parenting styles, low level of parental education, and poor academic performance. The comparatively high prevalence of depression among Iranian adolescents call for further investigation and measures. PMID:23618471

Adolescence is a key period for studying the development of depression, with studies in Europe and North America showing a pattern of elevated risk that begins in early adolescence and continues to increase as adolescents age. Few studies have examined the course of adolescent depression and associated risk factors in low and middle-income countries. This longitudinal cohort study examined depression symptom trajectories and risk factors in a sample of socio-economically disadvantaged adolescents in Chile (n = 2,508). Data were collected over an 18-month period as part of a clinical trial for secondary students aged 12 to 18 (median age 14). Clinical levels of depression were prevalent in this sample at baseline (35% for girls and 28% for boys); yet latent growth models of symptom trajectories revealed a pattern of decreasing symptoms over time. There was evidence of an anxiety-depression developmental pathway for girls, with elevated anxiety levels initially predicting poorer depression outcomes later on. Poor problem-solving skills were associated with initial depression levels but did not predict the course of depressive symptoms. Critically, the declining symptom trajectories raise important methodological issues regarding the effects of repeated assessment in longitudinal studies. PMID:24147131

Are sleep and depression independent or overlapping risk factors for cardiometabolic disease?

Mezick, Elizabeth J; Hall, Martica; Matthews, Karen A

2011-02-01

Sleep duration, sleep continuity, and depression are associated with cardiovascular disease and metabolic disorders. Despite the well-established relationship between sleep and depression, few studies examine these characteristics simultaneously in the development of cardiometabolic disease. Here, we review available studies that include measures of both sleep and depression in relation to cardiometabolic outcomes (cardiovascular disease, diabetes, and the metabolic syndrome). In general, data show that independent of depression, sleep continuity is a risk factor for cardiovascular disease, and short or long sleep duration is a risk factor for diabetes and the metabolic syndrome. Results for associations between sleep duration and cardiovascular disease, and associations between sleep continuity and metabolic disease, are more mixed. Regarding depression, there is preliminary evidence that depression increases risk for cardiovascular disease, independent of sleep continuity. However, there are insufficient data to address whether relationships between depression and cardiovascular and metabolic disease are independent of sleep duration. A number of biobehavioral mechanisms, including inflammation, hypothalamic and sympathetic dysregulation, and obesity and health behaviors, may account for the relationships among sleep, depression, and cardiometabolic disease. After summarizing these mechanisms, we discuss limitations of the extant literature and suggest directions for future research. © 2010 Elsevier Ltd. All rights reserved.

Depression is the most common psychiatric co-morbidity among people living with HIV (PLHIV), with prevalence rates ranging from 25% to 36%. Depression impacts negatively upon adherence and response to combined antiretroviral therapy (CART) and the transmission of HIV infection through increased sexually risky behavior. This cross-sectional study presents data from a reference HIV-outpatient service in Dourados (Brazil) that evaluated the association between depressive symptoms, health-related quality of life, and clinical, socioeconomic, and demographic factors in newly diagnosed HIV/AIDS patients. Using the Beck Depression Inventory (BDI), the prevalence of depressive symptoms was 61% with a predominance of self-deprecating and cognitive-affective factors. Depressive symptoms were associated with lower income (p=0.019) and disadvantaged social class (p=0.005). Poorer quality of life was related to depressive symptoms (p<0.0001), low educational level (p=0.05), and lower income (p=0.03). These data suggest that socioeconomic factors, including level of income and education, are mediating the risk of depression and poor quality of life of PLHIV. Possible explanations for this effect are discussed, including the possible role of stigma.

Peer victimization can have a profound effect on children’s wellbeing and is a known risk factor for depression in childhood. Migrant children experience peer victimization at higher rates than non-migrant peers; however, limited research has examined psychological factors that may serve to reduce depression risk for this group. In particular, no studies have yet investigated whether resilience, including personal characteristics, and a strong social support network, may moderate the relationship between peer victimization and depressive symptoms for migrant children. This study utilized a latent interaction model to examine the effect of resilience on the relationship between peer victimization and depressive symptoms among 721 rural-to-urban migrant children in Beijing, China. Results indicated that peer victimization was positively associated with depressive symptoms. Resilience was found to be a protective factor for depressive symptoms and also mitigated the effects of peer victimization on depressive symptoms. Exploratory analyses suggest that enrollment in private migrant schools may be linked with poorer psychosocial outcomes for Chinese migrant children. Strengthening the internal resilience and social supports for all migrant children may be an effective strategy to lower their risk for depression. Implications for intervention are discussed.

The risk factors of suicidal ideation and attempts have been discussed in many researches. Few studies have examined reasons for living and hope as protective factors against suicide in a clinical population. It is unclear if these factors help to reduce suicide rates in patients with depression. The study aimed to assess the role of reasons for living and hope in the identification and reduction of suicidality and explore the influence of reasons for living or hope in the transition from suicidal ideation to suicide attempts. Patients with depression (N = 115) completed the Beck Depression Inventory, Reasons for Living Inventory, and Adult Suicidal Ideation Questionnaire. There were significant correlations among depression, hope, total reasons for living, and suicidal ideation and attempts. Further, after controlling for depression, reasons for living and hope had significant main effects on suicidal ideation. Hope also had a significant predictive effect in the transition of suicidal ideation to suicide attempt. We concluded that reasons for living and hope may protect against suicidal ideation and attempts in patients with depression. Especially hope could reduce the possibility of suicide attempt.

The purpose of the present study was to assess the factor structure and reliability of the Depression, Anxiety and Stress Scales (DASS-21) in a large Portuguese community sample. Participants were 1020 adults (585 women and 435 men), with a mean age of 36.74 (SD = 11.90) years. All scales revealed good reliability, with Cronbach's alpha values between .80 (anxiety) and .84 (depression). The internal consistency of the total score was .92. Confirmatory factor analysis revealed that the best-fitting model (*CFI = .940, *RMSEA = .038) consisted of a latent component of general psychological distress (or negative affectivity) plus orthogonal depression, anxiety and stress factors. The Portuguese version of the DASS-21 showed good psychometric properties (factorial validity and reliability) and thus can be used as a reliable and valid instrument for measuring depression, anxiety and stress symptoms.

Millions of African children are having to grow up under harsh and adverse psychosocial conditions but it's not fully understood how this negative psychosocial environment is affecting their mental health. This paper examines the prevalence and risk factors of depression in childhood and adolescence as seen in a community sample derived from four disadvantaged districts in north-eastern Uganda. 1587 children were assessed using a structured instrument administered by trained psychiatric nurses to collect data on psychiatric disorders (DSM IV criteria), adverse psychosocial factors and socio-demographic factors. The point prevalence of depressive disorder syndromes (DDS) in this study was 8.6% (95% CI 7.2%-10.1%) with a point prevalence for major depressive episode of 7.6% (95% CI 6.3%-9.0%) and dysthymia of 2.1% (95% CI 1.5%-3.0%). At multiple logistic regression, the factors that were independently significantly associated with DDS were: district (representing ecological factors), nature of living arrangements, domestic violence and psychiatric co-morbidities/psychiatric problems of emotional distress (assessed by the SDQ), suicidality and marginally, anxiety disorder syndromes, eating disorder syndromes, motor disorder syndromes and behavioral and developmental disorder syndromes (the later being protective against depression). Disadvantaged north-eastern Uganda had a high prevalence of childhood depressive disorders. Ecological factors, markers of the quality of the child-principal caregiver relationship (nature of living arrangements and domestic violence) and the presence of psychiatric co-morbidities/psychiatric problems were the important independent determinants of childhood depression in this study.

Whether personality factors and depressive traits affect patients' utilization of health care following an acute myocardial infarction is relatively unknown. The aim of this study was to examine whether hospital-based health care utilization after a myocardial infarction was correlated with patients' personality factors and depressive symptoms. We studied 366 myocardial infarction patients admitted to Malmö University Hospital between 2002 and 2005 who subsequently participated in a cardiac rehabilitation programme. The patients were followed for two years after their index event. We investigated whether personality factors and depressive traits were correlated with the participants' health care utilization, defined as a) out-patient Cardiology visits and phone calls to a physician, nurse or a social worker, and b) acute visits or admissions to the Emergency or Cardiology Departments, using negative binominal regression analysis. In unadjusted comparisons neuroticism predicted more out-patient contacts. This significance remained after adjusting for age, sex, smoking, alcohol consumption and size of the myocardial infarction (measured as max level on troponin-I and left ventricular ejection fraction). There were no significant correlations between other personality factors or depression and out-patient contacts. None of the personality factors or depression predicted acute admissions. Apart from neuroticism, personality factors did not explain utilization of health care in terms of Cardiology out-patient contacts or acute admissions in myocardial infarction patients participating in a cardiac rehabilitation programme. Neither did depressive symptoms predict more health care utilization. This might indicate a robust cardiac rehabilitation programme offered to the study subjects, minimizing the need for additional health care contacts.

Doctors are less likely to diagnose depression in men than in women. Little research has been conducted to explore the underlying reasons for this in rural settings, or to compare primary care doctors' and male patients' ratings of perceived depression. To identify symptomatic and socio-demographic correlates of depression in men attending a rural practice, and to compare and contrast general practitioners' and patients' assessments of depression. All male patients of working age attending a rural general practice over a 12-month period were invited to participate. Men reporting recent "chest pain" or "feeling tired/little energy", expressing low job enjoyment or with a previous diagnosis of depression were more likely to be scored above threshold on the Hospital Anxiety and Depression Scale-Depression sub-scale. There was little agreement between the doctors and their male patients about the degree of perceived depression. Educational interventions aimed at addressing the diagnosis of depression in men should take greater account of factors within a particular social setting.

Asymptotic, multigroup flux reconstruction and consistent discontinuity factors

DOE PAGES

Trahan, Travis J.; Larsen, Edward W.

2015-05-12

Recent theoretical work has led to an asymptotically derived expression for reconstructing the neutron flux from lattice functions and multigroup diffusion solutions. The leading-order asymptotic term is the standard expression for flux reconstruction, i.e., it is the product of a shape function, obtained through a lattice calculation, and the multigroup diffusion solution. The first-order asymptotic correction term is significant only where the gradient of the diffusion solution is not small. Inclusion of this first-order correction term can significantly improve the accuracy of the reconstructed flux. One may define discontinuity factors (DFs) to make certain angular moments of the reconstructed fluxmore » continuous across interfaces between assemblies in 1-D. Indeed, the standard assembly discontinuity factors make the zeroth moment (scalar flux) of the reconstructed flux continuous. The inclusion of the correction term in the flux reconstruction provides an additional degree of freedom that can be used to make two angular moments of the reconstructed flux continuous across interfaces by using current DFs in addition to flux DFs. Thus, numerical results demonstrate that using flux and current DFs together can be more accurate than using only flux DFs, and that making the second angular moment continuous can be more accurate than making the zeroth moment continuous.« less

This study aimed to investigate factors affecting frailty by age groups among vulnerable elders in Korea. In this secondary analysis, data were collected from records for 22,868 eldesr registered in the Visiting Health Management program of Publci Health Centers in 2012. Health behaviors, clinically diagnosed disease, frailty, depression and cognitive condition were assessed. Data were analyzed using stepwise regression to determine the associated factors of frailty by age group. Alcohol consumption, physical activity, number of diseases, DM, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors significantly associated with frailty among the elders aged 65~74 (F=135.66, p<.001). Alcohol consumption, physical activity, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors associated with frailty in the elders aged 75~84 (F=245.40, p<.001). Physical activity, CVA, arthritis, depression and cognitive condition were factors associated with frailty in the elders over 85 years of age (F=96.48, p<.001). The findings show that frailty of elders and associated factors were different by age group, and common factors affecting frailty were physical activity, CVA, arthritis, depression and cognitive condition. Thus, these factors should be considered in the development of intervention program for care and prevention of frailty and program should be modified according to age group.

Stigma towards individuals experiencing a mental illness is associated with a range of negative psychological, social and financial outcomes. Factors associated with stigma remain unclear; the relationship between stigma and various personal factors may depend on both the type of disorder being stigmatised and what type of stigma is assessed. Different forms of stigma include personal stigma (negative attitudes towards others), perceived stigma (perceived attitudes of others) and self-stigma (self-attribution of others' negative attitudes). Three hundred and fifty university students and members of the general public completed an online survey assessing contact with and knowledge of both depression and anxiety, age, gender, current depression and anxiety symptoms, and personal, perceived and self-stigma for both depression and anxiety. Greater contact with, and knowledge of that illness predicted lower personal stigma for both anxiety and depression. Participants with greater levels of current depression symptomatology and females, reported higher perceived stigma towards depression. Males reported higher personal stigma for anxiety. For both anxiety and depression, higher current symptomatology was associated with greater levels of self-stigma towards the illness. Findings confirm the role of contact and knowledge in personal stigma for both disorders, consistent with previous findings. This finding also supports evidence that interventions addressing these factors are associated with a decline in personal stigma. However, lack of relationship between contact with, and knowledge of a mental illness and perceived and self-stigma for either depression or anxiety suggests that these factors may not play a major role in perceived or self-stigma. The identification of symptomatology as a key factor associated with self-stigma for both anxiety and depression is significant, and has implications for community-wide interventions aiming to increase help-seeking behaviour, as well as individual treatment strategies for clinicians. Further research should examine whether these relationships hold for groups with clinically diagnosed depression and anxiety disorders.

AIM To identify factors associated with depressive symptoms among inpatients with cardiovascular disease (CVD). METHODS This is a cross-sectional study performed in a subsample of a large cross-sectional research that investigated affective disorders and suicide behaviour among inpatients hospitalized in non-surgical wards of the University Hospital of the Federal University of Minas Gerais from November 2013 to October 2015. Sociodemographic and clinical data were obtained through a structured interview and medical record review. Depression was assessed by the depression subscale of the Hospital Anxiety and Depression Scale, with scores ≥ 8 considered as positive screening for depression. We used the Fageström Test for Nicotine Dependence to characterize nicotine dependence. For assessing resilience and early-life trauma, we used the raw scores of the Wagnild and Young Resilience Scale and Childhood Trauma Questionnaire, respectively. RESULTS At endpoint, we included 137 subjects. Thirty-eight (27.7%) subjects presented depressive symptoms and nine (23.7%) of those were receiving antidepressant treatment during hospitalization. The female sex; a lower mean educational level; a greater prevalence of previous suicide attempts; a higher level of pain; a higher prevalence of family antecedents of mental disorders; a lower resilience score; and higher childhood trauma score were the factors significantly associated with screening positive for major depression (P < 0.05). Multivariate analysis demonstrated that the factors independently associated with the depressive symptoms were a higher childhood trauma severity (OR = 1.06; P = 0.004); moderate to severe nicotine dependence (OR = 8.58; P = 0.008); and the number of previous hospital admissions (OR = 1.11; P = 0.034). The obtained logistic model was considered valid, indicating that the three factors together distinguished between having or not depressive symptoms, and correctly classified 74.6% of individuals in the sample. CONCLUSION Our results demonstrate that inpatients presenting both CVD and a positive screening for depression are more prone to have antecedents of childhood trauma, nicotine dependence and a higher number of previous hospitalizations.

The aim of this study was to explore the relationship between patient self-reported Patient Health Questionnaire-9 (PHQ-9) symptoms and doctor diagnosis of depression using a tree analysis approach. This was a secondary analysis on a dataset obtained from 10 179 adult primary care patients and 59 primary care physicians (PCPs) across Hong Kong. Patients completed a waiting room survey collecting data on socio-demographics and the PHQ-9. Blinded doctors documented whether they thought the patient had depression. Data were analyzed using multiple logistic regression and conditional inference decision tree modeling. PCPs diagnosed 594 patients with depression. Logistic regression identified gender, age, employment status, past history of depression, family history of mental illness and recent doctor visit as factors associated with a depression diagnosis. Tree analyses revealed different pathways of association between PHQ-9 symptoms and depression diagnosis for patients with and without past depression. The PHQ-9 symptom model revealed low mood, sense of worthlessness, fatigue, sleep disturbance and functional impairment as early classifiers. The PHQ-9 total score model revealed cut-off scores of >12 and >15 were most frequently associated with depression diagnoses in patients with and without past depression. A past history of depression is the most significant factor associated with the diagnosis of depression. PCPs appear to utilize a hypothetical-deductive problem-solving approach incorporating pre-test probability, with different associated factors for patients with and without past depression. Diagnostic thresholds may be too low for patients with past depression and too high for those without, potentially leading to over and under diagnosis of depression.

To explore the relation between the frequencies of apolipoprotein E (ApoE) alleles and the occurrence of depression in patients undergoing hemodialysis in a Chinese population. We examined the ApoE alleles in a sample of 288 subjects: 72 patients with depression under hemodialysis, 74 patients without depression under hemodialysis, 75 patients with depression under nondialytic treatment and 67 patients without depression under nondialytic treatment. The depression state was assessed using the Center for Epidemiological Studies Depression (CES-D) scale. Associations between the occurrence of depression and the frequencies of ApoE alleles were examined using multinomial logistic regression models with adjustment of relevant covariates. Information about sociodemographics, clinical data, vascular risk factors and cognitive function was also collected and evaluated. The frequencies of ApoE-ɛ2 were significantly different between depressed and non-depressed patients irrespective of dialysis (p < 0.05), but no significant difference was found in the frequencies of ApoE-ɛ4 (p > 0.05). Serum ApoE levels were significantly different between depressed and non-depressed patients in the whole sample (p < 0.05). Multinomial logistic regression models showed significant association between the frequency of ApoE-ɛ2 and the occurrence of depression in the Chinese population after control of relevant covariates, including age, sex, educational level, history of smoking and drinking, vascular risk factors and cognitive function. No association between the frequency of ApoE-ɛ4 and the occurrence of depression was found in patients undergoing hemodialysis. Further research is needed to find out if ApoE-ɛ2 acts as a protective factor in Chinese dialysis population since it might decrease the prevalence of depression and delay the onset age.

An area of extensive seafloor depressions occurs on the Southern Chatham Rise, New Zealand. The 2013 R/V Sonne SO-226 voyage aimed to investigate the formation and occurrences of these features and their possible relation to release of gas during glacial-interglacial cycles. The seafloor depressions occur in water depths of 500-1100m. This presentation focuses on a depression with a diameter of approximately 1km in a water depth of ~1000m. We present initial results from a high-resolution subsurface 3D seismic data cube collected across the seafloor depression. The data were collected using the P-Cable system, which has been developed specifically for imaging the shallow subsurface. The data shows an enigmatic conical-shaped feature underlying the seafloor depression with an area surrounding which has been initially interpreted as a giant gas chimney flow-zone. While geochemical results indicate no present day methane flux, the geophysical data shows a presence of blanking which may be associated with gas or gas hydrate close to the seafloor. We show first interpretations of the nature of this feature and its emplacement. Our preferred causes are either a volcanic cone or a mud diapir. We speculate that emplacement of this feature has been instrumental in forming the overlying seafloor depressions but are still evaluating the potential linkages.

Major depressive disorder has a large impact on patients and society and is projected to be the second greatest global burden of disease by 2020. The brain-derived neurotrophic factor (BDNF) gene is considered to be one of the important factors in the etiology of major depressive disorder. In a recent study, alpha power was found to mediate between BDNF Met and subclinical depressed mood. The current study looked at a population of patients with major depressive disorder (N = 107) to examine the association between the BDNF Val66Met polymorphism, resting state EEG alpha power, and depression severity. For this purpose, repeated-measures analysis of variance, partial correlation, and multiple linear models were used. Results indicated a negative association between parietal-occipital alpha power in the eyes open resting state and depression severity. In addition, Met/Met patients showed lower global absolute alpha power in the eyes closed condition compared with Val-carriers. These findings are in accordance with the previously uncovered pathway between BDNF Val66Met, resting state EEG alpha power, and depression severity. Additional research is needed for the clarification of this tentative pathway and its implication in personalized treatment of major depressive disorder.

Depression is one of the most common mental disorders in the United States and affects an estimated 17 million people each year. Projections about depression have generated concern on both the domestic and global levels because of its impact on health outcomes and quality of life. We examined and summarized published research focusing on depression among African American men with the goal of identifying prevalence of depression, risk factors, treatment-seeking behaviors, and treatment-seeking barriers. In the use of a systematic review, inclusion criteria were studies focused on depression among African American or Black men, separated analysis by race and gender, and conducted in the United States. Each study was critically reviewed to identify depression prevalence, risk factors, treatment-seeking behaviors, and barriers. Only 19 empirical studies focusing on depression among African American men were identified in a 25-year time span. Findings suggest the prevalence of depression among African American men ranges from 5% to 10%, they face a number of risk factors, yet evidence low use of mental health services. Consequently, depression among African American men needs to be at the forefront of our research, practice, and outreach agendas. A focus on this group has the potential to reduce mental health disparities experienced by African American men. PMID:23889029

To examine gender differences in depression risk and coping factors in a clinical sample of patients with a diagnosis of DSM-IV major depression. Patients were assessed for substance use and abuse, family history of psychiatric disorder, interpersonal depressogenic factors and lifetime history of anxiety disorders. Trait anxiety, coping styles when depressed, parental bonding, marital features and personality style were also measured. Patients were reassessed at 12-month follow-up. There were few gender differences in experience of depression (either in duration, type or severity prior to treatment) in a group with established episodes of major depression but women reported more emotional arousability when depressed. Women reported higher rates of dysfunctional parenting and childhood sexual abuse, and rated their partners as less caring and as more likely to be a depressogenic stressor. Men were more likely to have a generalized anxiety disorder at assessment, to use recreational drugs prior to presentation. Men were rated as having a more rigid personality style and 'Cluster A' personality traits both at assessment and follow-up. There were few gender differences in severity or course of established episodes of major depression. Gender differences were related to levels of arousal, anxiety disorders, and repertoires for dealing with depression, rather than depressive symptoms per se.

Within the clinical literature it is accepted that there is a strong connection between eating disorders and depression; however the nature of the casual relationship is somewhat unclear. Therefore the aim of the present study was to determine the prospective relationship between eating psychopathology and depressive symptoms among competitive British athletes. A total of 122 athletes completed the Eating Disorder Examination Questionnaire and the depression subscale of the Symptom Checklist-90R over a 6-month period. Partial correlations revealed that when controlling for baseline eating psychopathology, athletes' baseline depressive symptoms was not related to their eating psychopathology 6 months later. However, when controlling for baseline depressive symptoms, athletes' initial eating psychopathology was positively and significantly related to depressive symptoms 6 months later. Subsequent hierarchical multiple regression analyses revealed athletes' initial levels of eating psychopathology significantly predicted depressive symptoms 6 months later. The current findings support the assertion that elevated eating psychopathology serves as a potential risk factor for the development of depression in athletes. Thus, National Governing Bodies, athletic clubs, sport organisations and universities need to recognise and be aware that exposure to the factors that increase the risk of eating disorders inadvertently serves to increase athletes' vulnerability for depression.

Numerous factors influence late-life depressive symptoms in adults, many not thoroughly characterized. We addressed whether genetic and environmental influences on depressive symptoms differed by age, sex, and physical illness. The analysis sample included 24 436 twins aged 40-90 years drawn from the Interplay of Genes and Environment across Multiple Studies (IGEMS) Consortium. Biometric analyses tested age, sex, and physical illness moderation of genetic and environmental variance in depressive symptoms. Women reported greater depressive symptoms than men. After age 60, there was an accelerating increase in depressive symptom scores with age, but this did not appreciably affect genetic and environmental variances. Overlap in genetic influences between physical illness and depressive symptoms was greater in men than in women. Additionally, in men extent of overlap was greater with worse physical illness (the genetic correlation ranged from near 0.00 for the least physical illness to nearly 0.60 with physical illness 2 s.d. above the mean). For men and women, the same environmental factors that influenced depressive symptoms also influenced physical illness. Findings suggested that genetic factors play a larger part in the association between depressive symptoms and physical illness for men than for women. For both sexes, across all ages, physical illness may similarly trigger social and health limitations that contribute to depressive symptoms.

Studies suggest that family caregiver well-being (ie, depressive symptoms and life satisfaction) may affect stroke survivor depressive symptoms. We used mediation analysis to assess whether caregiver well-being might be a factor explaining stroke survivor depressive symptoms, after controlling for demographic factors and stroke survivor impairments and problems. Caregiver/stroke participant dyads (N = 146) completed measures of stroke survivor impairments and problems and depressive symptoms and caregiver depressive symptoms and life satisfaction. Mediation analysis was used to examine whether caregiver well-being mediated the relationship between stroke survivor impairments and problems and stroke survivor depressive symptoms. As expected, more stroke survivor problems and impairments were associated with higher levels of stroke survivor depressive symptoms (P < .0001). After controlling for demographic factors, we found that this relationship was partially mediated by caregiver life satisfaction (29.29%) and caregiver depressive symptoms (32.95%). Although these measures combined to account for 40.50% of the relationship between survivor problems and impairments and depressive symptoms, the direct effect remained significant. Findings indicate that stroke survivor impairments and problems may affect family caregivers and stroke survivors and a high level of caregiver distress may result in poorer outcomes for stroke survivors. Results highlight the likely importance of intervening with both stroke survivors and family caregivers to optimize recovery after stroke.

Depression, anxiety and stress have been recognized as important mental outcome measures in stressful working settings. The present study explores the prevalence of self-perceived depression, anxiety and stress; and their relationships with psychosocial job factors. A cross-sectional study involving 728 male automotive assembly workers was conducted in two major automotive assembly plants in Malaysia using the validated Malay versions of the Depression Anxiety Stress Scales (DASS) and Job Content Questionnaire (JCQ). Based on the DASS cut-off of > or =78 percentile scores, the prevalence of self-perceived depression, anxiety and stress was 35.4%, 47.2% and 31.1%, respectively. Four (0.5%), 29 (4.0%) and 2 (0.3%) workers, respectively, reported extremely severe self-perceived depression, anxiety and stress. Multiple linear regression analyses, controlling for age, education, salary, duration of work and marital status, revealed that psychological job demand, job insecurity and hazardous condition were positively associated with DASS-Depression, DASS-Anxiety and DASS-Stress; supervisor support was inversely associated with DASS-Depression and DASS-Stress. We suggest that reducing psychological job demand, job insecurity and hazardous condition factors may improve the self-perceived depression, anxiety and stress in male automotive assembly workers. Supervisor support is protective for self-perceived depression and stress.

Perinatal distress is a significant public health problem that adversely impacts the individual and their family. The primary objective of this systematic review and meta-analysis was to identify factors that partners can modify to protect each other from developing perinatal depression and anxiety. In accordance with the PRISMA statement, we reviewed the risk and protective factors associated with perinatal depression and anxiety symptoms that partners can potentially modify without professional assistance (PROSPERO reference CRD42014007524). Participants were new or expectant parents aged 16 years or older. The partner factors were sub-grouped into themes (e.g., instrumental support) based on a content analysis of the scale items and measure descriptions. A series of meta-analyses were conducted to estimate the pooled effect sizes of associations. We included 120 publications, reporting 245 associations with depression and 44 with anxiety. Partner factors with sound evidence that they protect against both perinatal depression and anxiety are: emotional closeness and global support. Partner factors with a sound evidence base for depression only are communication, conflict, emotional and instrumental support, and relationship satisfaction. This review is limited by the lack of generalizability to single parents and the inability to systematically review moderators and mediators, or control for baseline symptoms. The findings suggest that future prevention programs targeting perinatal depression and anxiety should aim to enhance relationship satisfaction, communication, and emotional closeness, facilitate instrumental and emotional support, and minimize conflict between partners.

To clarify the factors controlling temporal and spatial variations of soil carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) fluxes, we investigated these gas fluxes and environmental factors in a tropical rainforest in Peninsular Malaysia. Temporal variation of CO2 flux in a 2-ha plot was positively related to soil water condition and rainfall history. Spatially, CO2 flux was negatively related to soil water condition. When CO2 flux hotspots were included, no other environmental factors such as soil C or N concentrations showed any significant correlation. Although the larger area sampled in the present study complicates explanations of spatial variation of CO2 flux, our results support a previously reported bipolar relationship between the temporal and spatial patterns of CO2 flux and soil water condition observed at the study site in a smaller study plot. Flux of CH4 was usually negative with little variation, resulting in the soil at our study site functioning as a CH4 sink. Both temporal and spatial variations of CH4 flux were positively related to the soil water condition. Soil N concentration was also related to the spatial distribution of CH4 flux. Some hotspots were observed, probably due to CH4 production by termites, and these hotspots obscured the relationship between both temporal and spatial variations of CH4 flux and environmental factors. Temporal variation of N2O flux and soil N2O concentration was large and significantly related to the soil water condition, or in a strict sense, to rainfall history. Thus, the rainfall pattern controlled wet season N2O production in soil and its soil surface flux. Spatially, large N2O emissions were detected in wet periods at wetter and anaerobic locations, and were thus determined by soil physical properties. Our results showed that, even in Southeast Asian rainforests where distinct dry and wet seasons do not exist, variation in the soil water condition related to rainfall history controlled the temporal variations of soil CO2 flux, CH4 uptake, and N2O emission. The soil water condition associated with soil hydraulic properties was also the important controlling factor of the spatial distributions of these gas fluxes.

A population-based study of anxiety as a precursor for depression in childhood and adolescence.

Anxiety and depression co-occur in children and adolescents with anxiety commonly preceding depression. Although there is some evidence to suggest that the association between early anxiety and later depression is explained by a shared genetic aetiology, the contribution of environmental factors is less well examined and it is unknown whether anxiety itself is a phenotypic risk factor for later depression. These explanations of the association between early anxiety and later depression were evaluated. Anxiety and depressive symptoms were assessed longitudinally in a U.K. population-based sample of 676 twins aged 5-17 at baseline. At baseline, anxiety and depression were assessed by parental questionnaire. Depression was assessed three years later by parental and adolescent questionnaire. Shared genetic effects between early anxiety and later depression were found. A model of a phenotypic risk effect from early anxiety on later depression provided a poor fit to the data. However, there were significant genetic effects specific to later depression, showing that early anxiety and later depression do not index entirely the same genetic risk. Anxiety and depression are associated over time because they share a partly common genetic aetiology rather than because the anxiety phenotype leads to later depression.

[Mother-child agreement regarding the depressive symptoms and the quality of life of the child and its influencing factors in children with and without depression].

Mother-child agreement and influencing factors were studied in depressed and non-depressed children. We hypothesized that age and gender of the child and maternal depression influenced mother-child agreement; parents of depressed children underestimated the quality of life of their children; agreement was better in older and non-depressed children. We studied depressed children with Major Depressive Disorder (n = 354, mean age = 11.69 +/- 2.05 years), and non-depressed school-age children (n = 1695, mean age = 10.34 +/- 2.19 years). Psychiatric diagnosis was obtained by a semi-structured interview; depressive symptoms and quality of life were measured by self-reported questionnaires. Mother-child agreement about depressive symptoms increased as children got older. Mother-son reports showed significant difference, mother-daughter reports were similar. Depressed mothers reported more serious symptoms for their children. Depressed children's parent rated lower quality of life than children for themselves. Agreement was influenced by depression of the child and only marginally by age. Age and psychiatric illness of the examined person influences agreement, which finding may well be important in practice.

Posttraumatic stress disorder is often diagnosed with other mental health problems, particularly depression. Although PTSD comorbidity has been associated with more severe and chronic symptomology, relationships among commonly co-occurring disorders are not well understood. The purpose of this study was to review the literature regarding the development of depression comorbid with combat-related PTSD among military personnel. We summarize results of commonly tested hypotheses about the etiology of PTSD and depression comorbidity, including (1) causal hypotheses, (2) common factor hypotheses, and (3) potential confounds. Evidence suggests that PTSD may be a causal risk factor for subsequent depression; however, associations are likely complex, involving bidirectional causality, common risk factors, and common vulnerabilities. The unique nature of PTSD-depression comorbidity in the context of military deployment and combat exposure is emphasized. Implications of our results for clinical practice and future research are discussed. Published by Elsevier Ltd.

In a sample of 100 patients with recurrent major depression, we collected depression severity data early and late in acute-phase cognitive therapy, plus a wide range of psychosocial variables that have been studied extensively in depression research, including measures of interpersonal, cognitive, and social functioning, and personality traits using an inventory that is linked with the Big-Three tradition in personality assessment theory. By assessing this broad range of variables in a single study, we could examine the extent to which relations of these variables with depression were due to (a) a common factor shared across this diverse set of constructs, (b) factors shared among each type of construct (personality vs. psychosocial measures), or (c) specific aspects of the individual measures. Only the most general factor shared across the personality and psychosocial variables predicted later depression. PMID:14632375

Although major depressive disorder (MDD) has a variety of symptoms beyond the affective dimensions, the factor structure and contents of comprehensive psychiatric symptoms of this disorder have rarely been explored using the 18-item Brief Psychiatric Rating Scale (BPRS). We aimed to identify the factor structure of the 18-item BPRS in Korean MDD patients. A total of 258 MDD patients were recruited from a multicenter sample of the Clinical Research Center for Depression of South Korea study. Psychometric scales were used to assess overall psychiatric symptoms (BPRS), depression (Hamilton Depression Rating Scale), anxiety (Hamilton Anxiety Rating Scale), global severity (Clinical Global Impression of Severity Scale), suicidal ideation (Scale for Suicide Ideation), functioning (Social and Occupational Functioning Assessment Scale), and quality of life (World Health Organization Quality of Life Assessment-abbreviated version). Common factor analysis with oblique rotation was used to yield factor structure. A four-factor structure was designed and interpreted by the symptom dimensions to reflect mood disturbance, positive symptoms/apathy, bipolarity, and thought distortion/mannerism. These individual factors were also significantly correlated with clinical variables. The findings of this study support the view that the BPRS may be a promising measuring tool for the initial assessment of MDD patients. In addition, the four-factor structure of the BPRS may be useful in understanding the mood and psychotic characteristics of these patients. Copyright © 2014. Published by Elsevier Taiwan.

To identify risk factors associated with depression and anxiety in infertile women and men undergoing in vitro fertilization (IVF). Prospective study. A university hospital in Sweden during a 2-year period. 825 participants (413 women and 412 men). Primary Care Evaluation of Mental Disorders (PRIME-MD), based on the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), as the diagnostic tool for evaluating mood and anxiety disorders, and fertility history and outcome of IVF treatment collected from the patients' medical records. Risk factors associated with depression and anxiety disorders. A negative pregnancy test and obesity were the independent risk factors for any mood disorders in women. Among men, the only independent risk factor for depression was unexplained infertility. No IVF-related risk factors could be identified for any anxiety disorder. A negative pregnancy test is associated with an increased risk for depression in women undergoing IVF, but no risk of developing anxiety disorders is associated with the pregnancy test result after IVF. Pregnancy test results were not a risk factor for depression or anxiety among men. Copyright 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

Although it is well accepted that there is a close relationship between hypothyroidism and depression, previous studies provided inconsistent or even opposite results in whether subclinical hypothyroidism (SCH) increased the risk of depression. One possible reason is that the etiology of SCH in these studies was not clearly distinguished. We therefore investigated the relationship between SCH resulting from 131I treatment of Graves' disease and depression. The incidence of depression among 95 patients with SCH and 121 euthyroid patients following 131I treatment of Graves' disease was studied. The risk factors of depression were determined with multivariate logistic regression analysis. Thyroid hormone replacement therapy was performed in patients with thyroid-stimulating hormone (TSH) levels exceeding 10 mIU/L. Patients with SCH had significantly higher Hamilton Depression Scale scores, serum TSH and thyroid peroxidase antibody (TPOAb) levels compared with euthyroid patients. Multivariate logistic regression analysis revealed SCH, Graves' eye syndrome and high serum TPO antibody level as risk factors for depression. L-thyroxine treatment is beneficial for SCH patients with serum TSH levels exceeding 10 mIU/L. The results of the present study demonstrated that SCH is prevalent among 131I treated Graves' patients. SCH might increase the risk of developing depression. L-thyroxine replacement therapy helps to resolve depressive disorders in SCH patients with TSH > 10mIU/L. These data provide insight into the relationship between SCH and depression.

It is well-established that the incidence of major depressive disorder is increased in subjects with subthreshold depression. A new research area focuses on the possibilities of preventing the onset of major depressive disorders in subjects with subthreshold depression. An important research question for this research area is which subjects with subthreshold depression will develop a full-blown depressive disorder and which will not. We selected 154 older subjects with subthreshold depression (CES-D>16) but no DSM mood disorder from a longitudinal study among a large population based cohort aged between 55 and 85 years in The Netherlands. Of these subjects, 31 (20.1%) developed a mood disorder (major depression and/or dysthymia) at three-year or six-year follow-up. We examined risk factors and individual symptoms of mood disorder as predictors of onset of mood disorder. Two variables were found to be significant predictors in both bivariate and multivariate analyses: eating problems and sleep problems. The incidence of mood disorders differed strongly for different subpopulations, varying from 9% (for those not having any of the two risk factors) to 57% (for those having both risk factors). It appears to be possible to predict to a certain degree whether a subject with subthreshold depression will develop a mood disorder during the following years.

Examination of prevalence of depressive symptoms among older persons in home care (HC) and complex continuing care (CCC) hospitals/units, factors associated with depressive symptoms in those settings, and rate of antidepressant use among older persons with depressive symptoms. Observational study using data from interRAI assessments used in normal clinical practice. Logistic regression models were used to identify factors associated with depressive symptoms in the frail elderly and treatment approaches were described. Fourteen HC agencies and 134 CCC hospitals/units in Ontario, Canada. Older persons (N = 191,9871) aged 65 years and older, including 114,497 persons from HC and 77,490 persons from CCC. Data were collected using Resident Assessment Instrument 2.0 (RAI 2.0) (1996-2004) in CCC and Resident Assessment Instrument for Home Care (RAI-HC) (2003-2004) in HC. Prevalence of depressive symptoms among older HC enrollees was lower (12.0%) than in CCC (23.6%). It decreased significantly with age in HC (to about 6% in those older than 95 years) but there were not substantial age differences in CCC. Common factors associated with depressive symptoms in both types of care were cognitive impairment, instability of health, daily pain, disability in activities of daily living; however, advanced age lost its protective effect in CCC. Less than half of the persons in HC and CCC with depressive symptoms were treated with antidepressants and their use decreased with age. Undertreatment of depressive symptoms among older persons remains a serious problem. Learning more about factors associated with depressive symptoms among the oldest old might improve detection and treatment of depression.

Depression among elderly is an important public health problem responsible for considerable morbidity and disability. Causes of depression are multifactorial and often preventable. As there was dearth of community studies in Tamil Nadu, the present study was undertaken. The objective of this study is to estimate the prevalence of depression and to assess the factors which are associated with depression among elderly. A cross-sectional study was done from July 2014 to July 2015 among elderly in Kattankulathur block with a sample size of 690 by cluster sampling method. House-to-house interview was conducted using a predesigned, pre-tested questionnaire, and depression was assessed using geriatric depression scale-30. Data were analyzed using SPSS version 20 (Trial). The statistical tests used were proportions, Chi-square test. P<0.05 was considered to be statistically significant. The overall prevalence of depression was 35.5% (95% confidence interval: 31.9%-39.0%). Sociodemographic factors such as female sex, nuclear family, being widowed, unemployed status, low socioeconomic status, financially dependent, medical factors such as cardiac disease, visual impairment, arthritis, anemia, life events such as conflicts in family, death of the family member or close relative, and illness of self/family member were significantly associated with depression (P < 0.05). More strength of association for depression was seen with low socioeconomic status, nuclear family, low-intensity work, conflicts in the family, death of family members using multiple logistic regression. These findings show the need for proper care by the family members and counseling for the elderly which are of much importance in preventing depression.

Background Inflammation contributes to the development of depression in a subset of individuals, but risk factors that render certain individuals vulnerable to inflammation-associated depression are undetermined. Drawing from animal studies showing that reduced neuroplasticity mediates effects of inflammation on depression, we hypothesized that individuals genetically predisposed to lower levels of neuroplasticity would be more susceptible to inflammation-associated depression. The current study examined whether the Met allele of the BDNF Val66met polymorphism, which predisposes individuals to reduced levels of brain-derived neurotrophic factor (BDNF), a protein vital for neuroplasticity, moderates the association between inflammation and depressive symptoms. Methods Our sample was 112 women with early-stage breast cancer who had recently completed cancer treatment, which can activate inflammation. Participants provided blood for genotyping and assessment of circulating inflammatory markers, and completed a questionnaire assessing depressive symptoms, including somatic, affective, and cognitive dimensions. Results There was a significant interaction between C-reactive protein (CRP) and the BDNF Val66met polymorphism in predicting cognitive depressive symptoms (p=.004), such that higher CRP was related to more cognitive depressive symptoms among Met allele carriers, but not among Val/Val homozygotes. Post-hoc longitudinal analyses suggested that, for Met carriers, higher CRP at baseline predicted higher cognitive depressive symptoms across a one-year follow-up period (p<.001). Conclusion The BDNF Met allele may be a risk factor for inflammation-associated cognitive depressive symptoms among breast cancer survivors. Women with breast cancer who carry this genotype may benefit from early identification and treatment. Limitation BDNF genotype is an indirect measure of BDNF protein levels. PMID:26967918

To examine the prevalence and correlates of diagnosed depression among South Asians and white Europeans with type 1 and type 2 diabetes mellitus, attending a specialist diabetes clinic in the UK. A cross-sectional study was conducted using the hospital clinic's computerised database. Medical and demographic data were extracted for 6230 people with diabetes attending the clinic between 2003 and 2005. Multiple logistic regression was used to model ethnic differences in the probability of diagnosed depression after controlling for demographic and diabetes related factors. Analyses were conducted separately for type 1 and type 2 diabetes. The unadjusted prevalence of depression in people with type 1 and type 2 diabetes was 8.0% and 9.3%, respectively. Risk factors for depression in type 1 diabetes included female gender, diabetes related complications, and comorbidities. In people with type 2 diabetes the risk factors for depression included younger age, diabetes related complications, comorbidities, insulin use and deprivation. In addition, white Europeans were significantly more likely to be diagnosed with depression compared to South Asians (odds ratio (OR) 1.59, 95% confidence interval (CI) 1.21 to 2.08; p<0.001). Further interaction analyses revealed no evidence that the association between ethnicity and depression differed according to any of the other factors examined in this study. The findings add to the limited body of knowledge regarding ethnic differences in depression and diabetes. Among those with type 2 diabetes, white Europeans had nearly 60% higher adjusted odds of diagnosed depression compared to South Asians. Disparities may be due to differences in presentation or identification of depression between these two ethnic groups.

The data from nine centres in Europe which had used the Geriatric Mental Scale (GMS) AGECAT were analysed to compare prevalence of diagnoses in subjects aged 65 years and over living in the community. Levels of depressive illness were: Iceland 8.8%, Liverpool 10.0%; Zaragoza 10.7%; Dublin 11.9%; Amsterdam 12.0%; Berlin 16.5%; London 17.3%; Verona 18.3% and Munich 23.6%. Taking all levels of depression, five high (Amsterdam, Berlin, Munich, London and Verona) and four low (Dublin, Iceland, Liverpool, Zaragoza) scoring centres were identified. Meta-analysis of all 13,808 subjects yielded a mean level of depression of 12.3% (95% CI 11.8-12.9), 14.1% for women (95% CI 13.5-14.8) and 8.6% for men (95% CI 7.9-9.3). Symptom levels varied between centres: 40% of the total study population in Amsterdam reported depressive mood against only 26% in Zaragoza. To incorporate studies from other centres using other methods for depression identification, the EURO-D scale was developed from 12 items of the GMS and validated against other scales and expert diagnosis. A two factor solution emerged, an 'affective suffering factor' and a 'motivation factor'. The EURO-D scale was applied to 14 population based surveys. Depression score tended to increase with age unlike levels of prevalence of depression. Large between centre differences were evident in levels of depression unexplained by age, gender or marital status. These data show that depressive illness defined as suitable for intervention is common among older people in Europe. Opportunities for effective treatment are almost certainly being lost. Levels of depressive symptoms vary significantly between high and low scoring centres, prompting the next phase of this study, an examination of risk factors in Europe.

Few studies have investigated the role of protective factors for suicidal ideation, which include resilience and social support among psychiatric patients with depression and/or anxiety disorders who are at increased risk of suicide. Demographic data, history of childhood maltreatment, and levels of depression, anxiety, problematic alcohol use, resilience, perceived social support, and current suicidal ideation were collected from a total of 436 patients diagnosed with depression and/or anxiety disorders. Hierarchical multiple logistic regression analyses were used to identify the independent and interaction effects of potentially influencing factors. Moderate-severe suicidal ideation was reported in 24.5% of our sample. After controlling for relevant covariates, history of emotional neglect and sexual abuse, low resilience, and high depression and anxiety symptoms were sequentially included in the model. In the final model, high depression (adjusted odds ratio (OR)=9.33, confidence interval (CI) 3.99-21.77) and anxiety (adjusted OR=2.62, CI=1.24-5.53) were independently associated with moderate-severe suicidal ideation among risk factors whereas resilience was not. In the multiple logistic regression model that examined interaction effects between risk and protective factors, the interactions between resilience and depression (p<.001) and between resilience and anxiety were significant (p=.021). A higher level of resilience was protective against moderate-severe suicide ideation among those with higher levels of depression or anxiety symptoms. Our results indicate that resilience potentially moderates the risk of depression and anxiety symptoms on suicidal ideation in patients with depression and/or anxiety disorders. Assessment of resilience and intervention focused on resilience enhancement is suggested for suicide prevention. Copyright © 2014 Elsevier Inc. All rights reserved.

Quantifying benthic nitrogen fluxes in Puget Sound, Washington: a review of available data

Understanding benthic fluxes is important for understanding the fate of materials that settle to the Puget Sound, Washington, seafloor, as well as the impact these fluxes have on the chemical composition and biogeochemical cycles of marine waters. Existing approaches used to measure benthic nitrogen flux in Puget Sound and elsewhere were reviewed and summarized, and factors for considering each approach were evaluated. Factors for selecting an appropriate approach for gathering information about benthic flux include: availability of resources, objectives of projects, and determination of which processes each approach measures. An extensive search of literature was undertaken to summarize known benthic nitrogen fluxes in Puget Sound. A total of 138 individual flux chamber measurements and 38 sets of diffusive fluxes were compiled for this study. Of the diffusive fluxes, 35 new datasets were located, and new flux calculations are presented in this report. About 65 new diffusive flux calculations are provided across all nitrogen species (nitrate, NO3-; nitrite, NO2-; ammonium, NH4+). Data analysis of this newly compiled benthic flux dataset showed that fluxes beneath deep (greater than 50 meters) water tended to be lower than those beneath shallow (less than 50 meters) water. Additionally, variability in flux at the shallow depths was greater, possibly indicating a more dynamic interaction between the benthic and pelagic environments. The overall range of bottom temperatures from studies in the Puget Sound area were small (5–16 degrees Celsius), and only NH4+ flux showed any pattern with temperature. For NH4+, flux values and variability increased at greater than about 12 degrees Celsius. Collection of additional study site metadata about environmental factors (bottom temperature, depth, sediment porosity, sediment type, and sediment organic matter) will help with development of a broader regional understanding benthic nitrogen flux in the Puget Sound.

The aim of this study was to investigate the association between subjective memory complaints (SMCs) and depressive symptoms, with and without adjustment for genetic and family environmental factors. We conducted a cross-sectional study using twins and measured SMCs and depressive symptoms as outcomes and explanatory variables, respectively. First, we performed regression analyses using generalized estimating equations to investigate the associations between SMCs and depressive symptoms without adjustment for genetic and family environmental factors (individual-level analyses). We then performed regression analyses for within-pair differences using monozygotic (MZ) and dizygotic (DZ) twin pairs and MZ twin pairs to investigate these associations with adjustment for genetic and family environmental factors by subtracting the values of one twin from those of co-twin variables (within-pair level analyses). Therefore, differences between the associations at individual- and within-pair level analyses suggested confounding by genetic factors. We included 556 twins aged ≥ 20 years. In the individual-level analyses, SMCs were significantly associated with depressive symptoms in both males and females [standardized coefficients: males, 0.23 (95% CI 0.08-0.38); females, 0.35 (95% CI 0.23-0.46)]. In the within-pair level analyses using MZ and same-sex DZ twin pairs, SMCs were significantly associated with depressive symptoms. In the within-pair level analyses using the MZ twin pairs, SMCs were significantly associated with depressive symptoms [standardized coefficients: males, 0.32 (95% CI 0.08-0.56); females, 0.24 (95% CI 0.13-0.42)]. This study suggested that SMCs were significantly associated with depressive symptoms after adjustment for genetic and family environmental factors.

To investigate differences in risk factors for depression and anxiety, such as central nervous system involvement in systemic lupus erythematosus (SLE)/mixed connective tissue disease (MCTD), by comparing youth with SLE/MCTD to peers with type 1 diabetes mellitus (T1D). We conducted a cross-sectional study of 50 outpatient pairs, ages 8 years and above, matching subjects with SLE/MCTD and T1D by sex and age group. We screened for depression, suicidal ideation, and anxiety using the Patient Health Questionnaire-9 and the Screen for Childhood Anxiety Related Emotional Disorders, respectively. We collected parent-reported mental health treatment data. We compared prevalence and treatment rates between subjects with SLE/MCTD and T1D, and identified disease-specific risk factors using logistic regression. Depression symptoms were present in 23%, suicidal ideation in 15%, and anxiety in 27% of participants. Compared with subjects with T1D, subjects with SLE/MCTD had lower adjusted rates of depression and suicidal ideation, yet poorer rates of mental health treatment (24% vs 53%). Non-White race/ethnicity and longer disease duration were independent risk factors for depression and suicidal ideation. Depression was associated with poor disease control in both groups, and anxiety with insulin pump use in subjects with T1D. Depression and anxiety are high and undertreated in youth with SLE/MCTD and T1D. Focusing on risk factors such as race/ethnicity and disease duration may improve their mental health care. Further study of central nervous system and other disease-related factors may identify targets for intervention. Copyright © 2015 Elsevier Inc. All rights reserved.

2018-01-01

Background Although reducing socioeconomic inequalities in depression is necessary, their associated factors have rarely been studied. This study aimed to screen the potential contextual factors associated with income-based inequality in older adults’ depression. Methods Using data from the Japan Gerontological Evaluation Study (JAGES) of 2013, we conducted an ecological study covering 77 communities in Japan. Our measures of socioeconomic inequalities in depression were the slope index of inequalities (SII) and the relative index of inequalities (RII) of the prevalence of depressive symptoms across three income levels. We categorized available community-level factors, including socio-demographic factors, social participation, social relationships, subjective changes in the residential area, and the built environment. These indicators were aggregated from individual responses of 51,962 and 52,958 physically independent men and women, respectively, aged 65 years or more. We performed multiple linear regression analyses to explore factors with statistical significance of a two-tailed P-value less than 0.05. Results Factors associated with shallower gradients in depression for men included higher participation in local activities and reception or provision of social support, which did not show significant association among women. Perceived increases in unemployment and economic inequalities were positively associated with larger inequalities in both genders (P < 0.05). The built environment did not indicate any significant association. Conclusions A community environment fostering social activities and relationships might be associated with smaller income-based inequalities in depression. There is a need for more deterministic studies for planning of effective community interventions to address socioeconomic inequalities in depression. PMID:29093358

Depression and social support among women living with the substance abuse, violence, and HIV/AIDS syndemic: a qualitative exploration.

Intimate partner violence (IPV), HIV/AIDS, and substance use are described as the SAVA "syndemic" among low-income urban women because of their intersecting and synergistic presence in these women's lives. Depressive symptoms are significantly associated with these SAVA factors and although social support is potentially protective for depression, little is understood about its impact on depression associated with the SAVA syndemic. This paper investigates how women living with SAVA experience and describe depressive symptoms, and examines how the types of social support they access impact their experiences of SAVA and depressive symptoms. Qualitative, in-depth interviews were conducted with 24 HIV-positive, low-income, urban women who experienced IPV and used cocaine or heroin in their lifetime. Interviews were analyzed based on study aims, principles of thematic content analysis, and grounded theory. Women identified multiple SAVA factors as catalysts for depression and noted their synergistic effect on depressive symptoms, which were both a trigger for and a result of drug use. Women accessed varying sources of social support to address their SAVA factors and associated symptoms of depression, relying on informal sources for instrumental support related to IPV and formal sources for support related to HIV, drug use, and depression. These findings have important implications for health providers who serve SAVA-affected women, and suggest that comprehensively addressing all SAVA factors (and IPV in particular) and improving their access to quality social support at critical times is essential to improve their mental health.

To determine whether cerebral small-vessel disease (SVD) is a specific risk factor for depression, whether any association is mediated via white matter damage, and to study the role of depressive symptoms and disability on quality of life (QoL) in this patient group. Using path analyses in cross-sectional data, we modeled the relationships among depression, disability, and QoL in patients with SVD presenting with radiologically confirmed lacunar stroke (n = 100), and replicated results in a second SVD cohort (n = 100). We then compared the same model in a non-SVD stroke cohort (n = 50) and healthy older adults (n = 203). In a further study, to determine the role of white matter damage in mediating the association with depression, a subgroup of patients with SVD (n = 101) underwent diffusion tensor imaging (DTI). Reduced QoL was associated with depression in patients with SVD, but this association was not mediated by disability or cognition; very similar results were found in the replication SVD cohort. In contrast, the non-SVD stroke group and the healthy older adult group showed a direct relationship between disability and depression. The DTI study showed that fractional anisotropy, a marker of white matter damage, was related to depressive symptoms in patients with SVD. These results suggest that in stroke patients without SVD, disability is an important causal factor for depression, whereas in SVD stroke, other factors specific to this stroke subtype have a causal role. White matter damage detected on DTI is one factor that mediates the association between SVD and depression. © 2014 American Academy of Neurology.

Objectives This study aims to present the patterns of physical comorbidity in depressed patients and factors strongly associated with depression in a representative sample of Slovenian family practice attendees.Methods Medical data was obtained for 911 general practice attendees. Of them, 221 (24.3%) were diagnosed as depressed. The depressive states of the subjects were evaluated using the Composite International Diagnostic Interview (CIDI). Physical comorbidity was assessed with a questionnaire covering the most common health problems in the Slovenian adult population. Several psycho-social factors were also analysed.Results Those variables significantly related to ICD depression were included in multivariate binary logistic regression analysis, adjusted by age, gender and education. The calculation included the chi-square, odds ratio (OR) with confidence interval (95% CI) and P-value. A P-value < 0.05 was marked as statistically significant.Conclusions There was no significant difference in the number of concurrent chronic diseases in depressed and non-depressed subjects. The risk of depression was increased by the presence of several concomitant factors. The burden of somatic co-morbidity was shown to be smaller than the impact of psychosocial determinants, which also acted as protective factors: the feeling of safety at home and the absence of problems in intimate relationships. The abuse of alcohol and drugs by a family member and current poor financial situation were strongly associated with depression. The impact of concurrent incontinence and chronic bowel disease was also important, though somewhat weaker.

Depression is a serious, costly, and debilitating disorder that is understudied in rural women. Studies show that depression is associated with low social integration and support, but few studies investigate the relationship between depression and social network characteristics. This study examined the associations among women from three Ohio Appalachian counties enrolled in a health study, which aimed to collect information for a future social network smoking cessation intervention. An address-based sampling method was used to randomly select and recruit 404 women. A cross-sectional survey and interview were used to collect information about demographic, psychosocial, behavioral factors, and ego-centric social network characteristics, which are variables derived from an individual (ego) and her first degree contacts (alters). The CES-D scale assessed depressive symptoms. A multivariable logistic regression analysis described the association between these factors and participants with depression (defined as CES-D≥16). Higher network density, or greater number of relationships among alters divided by the total amount of alters, reduced the risk for depression (OR = 0.84, 95% confidence interval [CI] 0.73-0.95). Additionally, women with a high percentage of smoking alters were at greater risk for depression (OR = 1.19, 95% CI 1.02-1.39). Other factors associated with risk for depression included perceived stress score (OR = 1.34, 95% CI 1.24-1.45), loneliness score (OR = 1.37, 95% CI 1.05-1.80), and days with poor physical health (OR = 1.06, 95% CI 1.02-1.11). Findings suggest that psychosocial factors and social networks should be considered when addressing depression in clinical practice.

In Japan, the number of workers with depressive symptoms has increased recently, and long working hours are considered one of the main contributing factors. Currently, the number of workers engaging in discretionary work is small but is expected to increase, as a diverse method of employment is believed to contribute to workers' well-being. However, the factors related to discretionary workers' depressive symptoms are unclear. This study aimed to identify the factors associated with depressive symptoms in discretionary workers. The subjects were 240 male discretionary workers in a Japanese insurance company. A cross-sectional study was performed using a questionnaire that includes demographic characteristics, living and working conditions, work-related and non-work-related stressful events, and the Center for Epidemiologic Studies Depression Scale (CES-D). Depressive symptoms were assessed as more than 16 points on the CES-D. Multiple logistic regression models were employed to estimate odd ratios (OR) with 95% confidence intervals (95% CI) of depressive symptoms in relation to possible factors. Thirty-six subjects (15.5%) showed depressive symptoms. The depressive symptoms were significantly related to age (p = 0.04), presence of child(ren) (p = 0.02), and length of employment (p = 0.01), but unrelated to working hours. Subjects who reported "financial matters" (OR = 4.50, 95% CI = 1.89-10.72) and "own event" such as divorce or illness (OR = 2.93, 95% CI = 1.13-7.61) were more likely to show depressive symptoms. In conclusion, mental health measures for discretionary workers should focus on addressing financial difficulties and consultations and assistance in personal health and family issues.

To investigate the relationship between unhealthy lifestyles factors and depressive symptoms among the general adult population in Japan. Participants were randomly selected from the Japanese general adult population. Data from 2334 people aged 20 years or older were analyzed. This cross-sectional survey was conducted in August and September 2009. Participants completed a face-to-face interview about unhealthy lifestyle factors, including lack of exercise, skipping breakfast, a poorly balanced diet, snacking between meals, insufficient sleep, current smoking, alcohol drinking, and obesity. Presence of depressive symptoms was defined as a score of ≥ 16 on the Japanese version of the Center for Epidemiologic Studies Depression Scale (CES-D). Relationships between unhealthy lifestyle factors and depressive symptoms were evaluated by multivariate logistic regression analysis adjusting for sociodemographic variables and other unhealthy lifestyle factors. Multivariate logistic regression analysis revealed that insufficient sleep, a poorly balanced diet, snacking between meals and lack of exercise were significantly associated with the prevalence of depressive symptoms, with odds ratios ranging from 1.56 for lack of exercise to 3.98 for insufficient sleep. Since this study was a cross-sectional study, causal relationships could not be determined. These results suggest that promoting a healthy lifestyle focused on sleep, food intake and exercise may be important for individuals with depressive symptoms. Copyright © 2018 Elsevier B.V.

Higher education has been associated with distress and depression in students, and concerns that the proportion students afflicted is increasing have been raised. Findings on student depression have often been based on age-homogeneous samples leaving the results vulnerable to a confounding of student experience, transition from adolescence to adulthood and age on depression. We investigated self-reported depression and its associations with sociodemographic and educational factors in a demographically diverse student population of first-year nursing students in Sweden. A base-line survey in a nation-wide cohort of 1,700 first-year nursing students was conducted in the fall of 2002. The participants answered a mailed questionnaire containing questions on sociodemography, educational factors, and health. Depression was measured by the Major Depression Inventory and associations to sociodemographic and educational factors were tested in logistic regressions. The overall response rate was 72.9%, and 10.2% (5.7% men, 10.7% women) reported depression. Younger age (<30), female gender, immigration from outside of Europe, high workload, dissatisfaction with education, low self-efficacy, and conflicts between personal and college demands were associated with high prevalence of depression. Prior work experience, less need for financial support, and work for pay during term time were related to low prevalence of depression. Older students and those who were parents reported home-college conflicts more often. Nursing students as a group show high levels of self-reported depression but the prevalence is affected by age with a higher proportion depressed among younger students. Even though older students and those who were parents show less depression, they were more vulnerable to home-college conflicts. As older students and parents constitute a large proportion of nursing students, it is of importance to find ways to lessen the effects of the obstacles they encounter in the education.

To understand the influential factors for depression in patients with facial acne vulgaris and to provide scientific evidence for a comprehensive and systematic treatment for acne vulgaris.
 A total of 287 outpatients with facial acne vulgaris, who visited the dermatology of the Third Xiangya Hospital, were surveyed by Beck Depression Inventory (BDI). The data was collected by Epidata software (version 3.1) and processed by SPSS software package (version 18.0). The influential factors for the depression of outpatients with facial acne vulgaris were analyzed by multinomial logistic regression.
 A total of 181 patients with facial acne vulgaris showed various degrees of depression (BDI score≥5) and the rate was 63.1%. The symptoms for depression included sad and pessimistic attitude as well as the decreased attention to others (social withdrawal). The influential factors for mild, moderate or severe depression were gender, the degree and the course of acne. Female patients were more likely to suffer mild, moderate or severe depression (OR=3.62, 2.63, respectively); the risk of depression in acne patients was increased with the increase in degree of the severity (OR=2.31, 4.51, respectively); the patients with the acne course more than a year were more likely to show mild depression than those with a course less than a year (OR=4.30, 7.44, respectively). The patients with acne course more than 3 years were more likely to show moderate or severe depression compared to those with a course less than a year (OR=3.60).
 Most of facial acne patients show a different degree of depression. The acne course is longer in female patients. The more severe the acne vulgaris is, the more suffering of the depression is. Psychological care should be considered to improve the treatment and quality of life.

Depression and anxiety are common among long-term care residents, yet both appear to be under-recognized and under-treated. In our survey of 164 geriatric health care professionals from 34 U.S. states, 96% of respondents reported that a new instrument that rapidly assesses both depression and anxiety is needed. The Brief Anxiety and Depression Scale (BADS) is a new screening tool that can identify possible major depressive episodes (MDE) and generalized anxiety disorders (GAD) in long-term care residents. The psychometric properties of the BADS were investigated in a sample of 224 U.S. long-term care residents (aged 80.52 ± 9.07). Participants completed a battery of several individually administered mood and cognitive tests, including the BADS. MDE and GAD were diagnosed based on the DSM-IV-TR criteria. Adequate internal consistency and construct validity were found. A principle component analysis (PCA) revealed an Anxiety Factor and a Depression Factor, which explained 50.26% of the total variance. The Anxiety Factor had a sensitivity of 0.73 and specificity of 0.81 for identifying GAD (PPV = 0.69, NPV = 0.84). The Depression Factor had a sensitivity of 0.76 and a specificity of 0.73 for identifying MDE (PPV = 0.77, NPV = 0.72). The BADS appears to be a reliable and valid screening instrument for MDE and GAD in long-term residents. The BADS can be rapidly administered, is sensitive to mood diagnoses in both patients without dementia and with dementia, and produces separate depression and anxiety factor scores that can be used clinically to identify probable mood diagnoses.

Interactive effects of genetic polymorphisms and childhood adversity on brain morphologic changes in depression.

PubMed

Kim, Yong-Ku; Ham, Byung-Joo; Han, Kyu-Man

2018-03-10

The etiology of depression is characterized by the interplay of genetic and environmental factors and brain structural alteration. Childhood adversity is a major contributing factor in the development of depression. Interactions between childhood adversity and candidate genes for depression could affect brain morphology via the modulation of neurotrophic factors, serotonergic neurotransmission, or the hypothalamus-pituitary-adrenal (HPA) axis, and this pathway may explain the subsequent onset of depression. Childhood adversity is associated with structural changes in the hippocampus, amygdala, anterior cingulate cortex (ACC), and prefrontal cortex (PFC), as well as white matter tracts such as the corpus callosum, cingulum, and uncinate fasciculus. Childhood adversity showed an interaction with the brain-derived neurotrophic factor (BDNF) gene Val66Met polymorphism, serotonin transporter-linked promoter region (5-HTTLPR), and FK506 binding protein 51 (FKBP5) gene rs1360780 in brain morphologic changes in patients with depression and in a non-clinical population. Individuals with the Met allele of BDNF Val66Met and a history of childhood adversity had reduced volume in the hippocampus and its subfields, amygdala, and PFC and thinner rostral ACC in a study of depressed patients and healthy controls. The S allele of 5-HTTLPR combined with exposure to childhood adversity or a poorer parenting environment was associated with a smaller hippocampal volume and subsequent onset of depression. The FKBP5 gene rs160780 had a significant interaction with childhood adversity in the white matter integrity of brain regions involved in emotion processing. This review identified that imaging genetic studies on childhood adversity may deepen our understanding on the neurobiological background of depression by scrutinizing complicated pathways of genetic factors, early psychosocial environments, and the accompanying morphologic changes in emotion-processing neural circuitry.

This study tests a novel, within-person model that reexamines depression and stress as risk factors for suicidal ideation and behavior among adolescent girls with and without sexual/physical abuse histories. This longitudinal study includes data from 220 adolescent girls between 12 and 16 years of age (M = 14.69 years, SD = 1.37; 61% White). At baseline, adolescents reported the presence or absence of prior abuse as part of a clinical interview. At baseline and every 3 months for 18 months, adolescents completed measures of suicidal ideation and behavior, depressive symptoms, and stress. Multilevel models examined within-person mean, deviations from within-person mean, depression, and stress and their interactions with abuse as predictors of suicidal ideation and behavior. In addition to within-person mean depression, higher-than-usual depression (odds ratio [OR] = 1.99) and higher-than-usual stress (OR = 1.53) predicted greater risk of suicidal ideation at each follow-up assessment. Periods of higher-than-usual stress (1 SD increase) and periods of higher-than-usual depression (1 SD increase) were associated with an 82% and 57% increase in the odds of suicidal behavior, respectively, but only among those with abuse histories. Depression, stress, and abuse are well-known risk factors for suicidal ideation and behavior; however, it has been unclear for whom, and when, these factors have their greatest impact. These results show that depression and stress are potent risk factors among those with a history of abuse and that within-person elevations in these risk factors signal increased short-term risk of suicidal ideation and behavior.

Suicide rates are highest among the elderly in Switzerland. The estimated number of unreported cases is particularly high in this age group. The risk factors are multidimensional, including depression and social isolation. The detection and management of the controllable risk factors, foremost depression, is of particular importance for suicide prevention. Old age depression often shows an atypical presentation, is misinterpreted as a normal process of aging and is not adequately treated.

This study examined (a) transition patterns from adolescent-specific depressive symptom trajectory classes to young adult-specific trajectory classes (N = 537; 15-26 years) and (b) identified risk factors associated with these transition patterns. The latent classes and transition analyses identified three transitional patterns of depressive symptom trajectories, including a deteriorating pattern (8.2%), a recovering pattern (22.5%), and a consistently low pattern (69.3%). Additionally, the results showed that contextual risk factors (i.e., negative economic events, negative romantic relationships, and low college enrolment rates) in the transition period to young adulthood were more positively associated with deteriorated or recovered transition patterns of depressive symptom trajectories than with the consistently low transition patterns even after taking into account the effects of adolescent risk factors. The identification of dynamic transition patterns in depressive symptom trajectories from adolescence to young adulthood and risk factors provide useful tools for preventive and intervention efforts. Statement of contribution What is already known on this subject? Heterogeneous trajectories of depressive symptoms across adolescence and young adulthood have been reported. Psychosocial characteristics differentiate trajectories of depressive symptoms from adolescence to young adulthood. What does this study add? Dynamic transition patterns of depressive symptom trajectories are found between adolescence and young adulthood. Life experiences in the transition period are uniquely associated with the transition patterns of depressive symptom trajectories even after adjusting the effects of adolescent characteristics. © 2017 The British Psychological Society.

OBJECTIVES The aim of the present study was to evaluate the relation of smoking with anxiety and depression in workers who were exposed to occupational risk factors. For this purpose, working time, smoking status, nicotine dependence, and respiratory functions of the workers who were exposed to physical and/or chemical harmful substances were evaluated and the presence of anxiety/depression was investigated. MATERIAL AND METHODS Male workers who were exposed to occupational risk factors such as solvents, heavy metals, and dust and visited the outpatient clinic for occupational diseases within a one-year period were included. Pulmonary Function Test and Fagerström Test for Nicotine Dependence were performed. Anxiety and depression statuses of the workers were assessed using the Hospital Anxiety and Depression Scale. RESULTS The mean age of 665 male workers was 45 y (range, 38–48 y), and they were most commonly exposed to solvents (45.9%), followed by heavy metal fume/dust (20.9%). Of the workers, 252 (37.9%) had anxiety, 294 (44.2%) had depression, and 171 (25.7%) had both. More than half of the workers in each occupation/exposure group were smokers. Respiratory complaints were present in 34% of the workers. According to the regression analysis, the presence of respiratory system complaints was found to be a significant risk factor for anxiety, depression, and anxiety plus depression. CONCLUSION In conclusion, smoking and anxiety/depression were found to be the conditions affecting more than half of the workers with occupational exposure. PMID:29755811

OBJECTIVE To describe the presenting symptoms of women with depression in two obstetrics and gynecology clinics, determine depression diagnosis frequency, and examine factors associated with depression diagnosis. METHODS Data were extracted from charts of women screening positive for depression in a clinical trial testing a collaborative care depression intervention. Bivariate and multivariable analyses examined patient factors associated with the diagnosis of depression by an obstetrician–gynecologist (ob-gyn). RESULTS Eleven percent of women with depression presented with a psychologic chief complaint but another 30% mentioned psychologic distress. All others noted physical symptoms only or presented for preventive care. Ob-gyns did not identify 60% of women with a depression diagnosis. Depression severity was similar in women who were or were not diagnosed by their ob-gyns. Bivariate analyses showed four factors significantly associated with depression diagnosis: reporting a psychologic symptom as the chief complaint or associated symptom (72% compared with 18.6%, P<.001), younger age (35.5 years compared with 40.8 years, P<.005), being within 12 months postpartum (13.9% compared with 2.8%, P<.005), and a primary care-oriented visit (72% compared with 30%, P<.001). Multivariable analysis showed that reporting a psychologic symptom (adjusted odds ratio [OR] 8.90, 95% confidence interval [CI] 4.15–19.10, P<.001), a primary care oriented visit (adjusted OR 2.46, 95% CI 1.14–5.29, P=.03), and each year of increasing age (adjusted OR 0.96, 95% CI 0.93–0.96, P=.02) were significantly associated with a depression diagnosis. CONCLUSION The majority of women with depression presented with physical symptoms; most women with depression were not diagnosed by their ob-gyn, and depression severity was similar in those diagnosed and those not diagnosed.

To examine predictors of depression persistence after a positive screening test to inform management protocols for screened youth. We conducted a cohort study of 444 youth (aged 13-17 years) from a large health care delivery system. Youth with depressive symptoms, based on a 2-item depression screen, were oversampled for the baseline interview. Baseline assessments included the Patient Health Questionnaire 9-item (PHQ-9) depression screen as well as clinical factors that were hypothesized to influence depression persistence (family history of depression, functional impairment, perceived social support, anxiety symptoms, externalizing symptoms, and medical comorbidity). Logistic regression analysis was used to examine factors associated with the persistence of depression at 6 months postbaseline. Of 113 youth with a positive baseline screen (PHQ-9 ≥11), 47% and 35% continued to be positive at 6-week and 6-month follow-up, respectively. After controlling for treatment status, only 2 factors were significantly associated with depression persistence at 6 months: baseline depressive symptom score and continuing to have a positive screen at 6 weeks. For each 1-point increase on the PHQ-9 score at baseline, youth had a 16% increased odds of continuing to be depressed at 6 months (odds ratio: 1.16, 95% confidence interval: 1.01-1.34). Youth who continued to screen positive 6 weeks later had almost 3 times the odds of being depressed at 6 months (odds ratio: 2.89, 95% confidence interval: 1.09-7.61). Depressive symptom severity at presentation and continued symptoms at 6 weeks postscreening are the strongest predictors of depression persistence. Patients with high depressive symptom scores and continued symptoms at 6 weeks should receive active treatment.

Depressive symptoms in people with diabetes are associated with increased risk of adverse outcomes. Although successful psychosocial treatment options are available, little is known about factors that facilitate treatment response for depression in diabetes. This prospective study aims to examine the impact of known risk factors on improvement of depressive symptoms with a special interest in the role of diabetes-related distress. 181 people with diabetes participated in a randomized controlled trial. Diabetes-related distress was assessed using the Problem Areas In Diabetes (PAID) scale; depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. Multiple logistic and linear regression analyses were used to assess associations between risk factors for depression (independent variables) and improvement of depressive symptoms (dependent variable). Reliable change indices were established as criteria of meaningful reductions in diabetes distress and depressive symptoms. A reliable reduction of diabetes-related distress (15.43 points in the PAID) was significantly associated with fourfold increased odds for reliable improvement of depressive symptoms (OR = 4.25, 95% CI: 2.05-8.79; P<0.001). This result was corroborated using continuous measures of diabetes distress and depressive symptoms, showing that greater reduction of diabetes-related distress independently predicted greater improvement in depressive symptoms (ß = -0.40; P<0.001). Higher age had a positive (Odds Ratio = 2.04, 95% CI: 1.21-3.43; P<0.01) and type 2 diabetes had a negative effect on the meaningful reduction of depressive symptoms (Odds Ratio = 0.12, 95% CI: 0.04-0.35; P<0.001). The reduction of diabetes distress is a statistical predictor of improvement of depressive symptoms. Diabetes patients with comorbid depressive symptomatology might benefit from treatments to reduce diabetes-related distress.

This study examined knowledge and beliefs about depression among Malaysian Malays varying in socioeconomic status. A total of 153 urban and 189 rural participants completed a questionnaire in which they had to identify two cases of depression and rate a series of items about the causes and best treatments for depression. Results showed that urban participants were more likely to use psychiatric labels ('depression') for the two vignettes, whereas rural participants tended to use more generic terms ('emotional stress'). Principal components analysis (PCA) showed that beliefs about the causes of depression factored into five components, of which stressful life events was most strongly endorsed by both groups. PCA of treatment items revealed four stable components, of which religious factors were most strongly endorsed. There were also a number of significant between-group differences in the endorsement of these factors (eta(p) (2) = .03-.11), with rural participants generally rating supernatural and religious factors more strongly than urban Malays. These results are discussed in relation to mental health literacy programmes in Malaysia.

Do some life story patterns exist, which are associated with depression? Can some life story factors be identified, which influence or determine a special kind of personality, predisposing to depression? Retrospective, cross sectional study with nonexperimental character, using a number of 60 nonmelancholic depressed patients. First, they were asked to give an interview on their life story. Then, they were asked to fill in questionnaires about personality, parental style of raising, clinical symptoms and personality disorders. Significant correlations could be found between parental style of raising, a family history affected by depression, a dysfunctional household, the family composition, negative school experience and all investigated styles of personality. Further, clusters of personality, clusters of parental style of raising and clusters of specific life story factors could be detected. Results show a strong relation between life story factors and personality styles, predisposing to depression and emphasize the importance of considering personality, when exploring special life story factors. Vice versa, actual personality styles can point to different patterns of life story and thus, show the relevance for the diagnostic and therapeutic process.

Depression in dialysis populations is affected by co-morbid diseases, such as cardiovascular disease, diabetes, and immune dysfunction, and it also includes high suicide risk and frequent hospitalizations. Depressive disorders have a close association with malnutrition and chronic inflammation, as well as with cognitive impairment. Impaired cognitive function may be manifested as low adherence to dialysis treatment, leading to malnutrition. Additionally, chronic pain and low quality of sleep lead to high rates of depressive symptoms in haemodialysis patients, while an untreated depression can cause sleep disturbances and increased mortality risk. Depression can also lead to sexual dysfunction and non-adherence, while unemployment can cause depressive disorders, due to patients' feelings of being a financial burden on their family. The present review provides a holistic approach to the factors affecting depression in haemodialysis, offering significant knowledge to renal professionals.

Depression is a frequent symptom in multiple sclerosis (MS) which has a negative impact on quality of life and cognitive status. The purpose of this study was to determine the prevalence and associated factors of depression, and status of antidepressant use in Iranian MS patients. One-hundred and sixty patients with definite MS were included. Demographic and clinical characteristics were recorded. Fatigue and depression were evaluated using the fatigue severity scale and Beck depression inventory-II. Cognitive performance and disability were examined by mini-mental status examination and expanded disability status scale. Multiple logistic regressions were used to determine the associated factors of depression and antidepressant use. The prevalence of depression and severe depression was 59.4 and 18.1 %, respectively. However, only 21.1 % of patients were on antidepressant treatment, while the prevalence of unrecognized/untreated depression was found to be as high as 44.1 %. Multivariable analysis showed that fatigue (P < 0.0001, OR = 5.98, 95 % CI = 2.9-12.3) and older age (P = 0.027, OR = 2.24, 95 % CI = 1.09-4.6) were associated with depression in MS patient. A significant association was found between fatigue and antidepressant use (P = 0.001, OR = 6.81, 95 % CI = 2.26-20.48). Our findings demonstrate that depression is significantly associated with fatigue and older age, regardless of other factors. Moreover, despite the high prevalence of depression in MS, most patients do not receive adequate treatment.

Depression, a type of mental disorder which is portrayed by marked alterations in mood, is associated with distress and/or impaired functioning. Poor social support is an important risk factor for depression in pregnancy. An extensive literature search failed to show any published study conducted in Malaysia on antenatal depressive symptoms and the risk of poor social support on it. The aim of the study was to determine the risk of antenatal depressive symptoms due to poor social support. This cross sectional study was conducted among 3000 pregnant women attending antenatal clinics in Penang, Malaysia. Edinburgh Postnatal Depression Scale (EPDS) was used to screen for antenatal depressive symptoms and the Oslo-3 Social Support Scale (OSS-3) was used to measure social support. Odds ratio and adjusted odds ratio were used to quantify the risk of antenatal depressive symptoms due to poor social support. The prevalence of depressive symptoms was 20%. Using OSS-3 scale to gauge social support, most of the participants had moderate support (61.3%) followed by poor support (22%) and strong support (16.7%). Social support was found to be significantly associated with depressive symptoms in this study (OR 2.2, aOR 2.1, AR 45%). Considering that an expecting mother's psychological factors are important in the wellbeing of the mother and child, antenatal depression must be quickly identified. Screening pregnant women for social support can help identify women with higher risk of depression.

Depression and the risk for dementia.

PubMed

Kessing, Lars Vedel

2012-11-01

Depression is associated with increased risk of subsequent development of dementia; however, the nature of the association is still poorly understood. The purpose of the review was based on recent studies to discuss whether depression is a prodromal state of dementia or an independent risk factor for dementia, as well as to discuss how the type of depression, the type of dementia, and antidepressant treatment influence the association. Findings from recent studies suggest that some forms of depressive illness, for example early-onset depression before age 65 years and recurrent depression, may constitute long-term risk factors for development of dementia, whereas the onset of more recent depressive symptoms may reflect a prodromal phase of dementia. It is not clear whether specific subtypes of depression correspond to specific types of dementia. Recent studies suggest that long-term treatment with antidepressants may decrease the risk of developing some types of dementia, depending on the type of depressive disorder. This review has shown that the type of depression and dementia, as well as the effect of drug treatment, has to be considered to improve knowledge on the association between depression and dementia.

Perinatal and early life factors associated with symptoms of depression in Brazilian children

PubMed Central

2012-01-01

Background Few studies have been conducted on the association between perinatal and early life factors with childhood depression and results are conflicting. Our aim was to estimate the prevalence and perinatal and early life factors associated with symptoms of depression in children aged 7 to 11 years from two Brazilian birth cohorts. Methods The study was conducted on 1444 children whose data were collected at birth and at school age, in 1994 and 2004/2005 in Ribeirao Preto, where they were aged 10–11 years and in 1997/98 and 2005/06 in São Luís, where children were aged 7–9 years. Depressive symptoms were investigated with the Child Depression Inventory(CDI), categorized as yes (score ≥ 20) and no (score < 20). Adjusted and non-adjusted prevalence ratios (PR) were estimated by Poisson regression with robust estimation of the standard errors. Results The prevalence of depressive symptoms was 3.9% (95%CI = 2.5-5.4) in Ribeirão Preto and 13.7% (95%CI = 11.0-16.4) in São Luís. In the adjusted analysis, in Ribeirão Preto, low birth weight (PR = 3.98; 95%CI = 1.72-9.23), skilled and semi-skilled manual occupation (PR = 5.30; 95%CI = 1.14-24.76) and unskilled manual occupation and unemployment (PR = 6.65; 95%CI = 1.16-38.03) of the household head were risk factors for depressive symptoms. In São Luís, maternal schooling of 0–4 years (PR = 2.39; 95%CI = 1.31-4.34) and of 5 to 8 years (PR = 1.80; 95%CI = 1.08-3.01), and paternal age <20 years (PR = 1.92; 95%CI = 1.02-3.61), were independent risk factors for depressive symptoms. Conclusions The prevalence of depressive symptoms was much higher in the less developed city, São Luís, than in the more developed city, Ribeirão Preto, and than those reported in several international studies. Low socioeconomic level was associated with depressive symptoms in both cohorts. Low paternal age was a risk factor for depressive symptoms in the less developed city, São Luís, whereas low birth weight was a risk factor for depressive symptoms in the more developed city, Ribeirão Preto.

Annual Research Review: An expanded account of information-processing mechanisms in risk for child and adolescent anxiety and depression.

PubMed

Lau, Jennifer Y F; Waters, Allison M

2017-04-01

Anxiety and depression occurring during childhood and adolescence are common and costly. While early-emerging anxiety and depression can arise through a complex interplay of 'distal' factors such as genetic and environmental influences, temperamental characteristics and brain circuitry, the more proximal mechanisms that transfer risks on symptoms are poorly delineated. Information-processing biases, which differentiate youth with and without anxiety and/or depression, could act as proximal mechanisms that mediate more distal risks on symptoms. This article reviews the literature on information-processing biases, their associations with anxiety and depression symptoms in youth and with other distal risk factors, to provide direction for further research. Based on strategic searches of the literature, we consider how youth with and without anxiety and/or depression vary in how they deploy attention to social-affective stimuli, discriminate between threat and safety cues, retain memories of negative events and appraise ambiguous information. We discuss how these information-processing biases are similarly or differentially expressed on anxiety and depression and whether these biases are linked to genetic and environmental factors, temperamental characteristics and patterns of brain circuitry functioning implicated in anxiety and depression. Biases in attention and appraisal characterise both youth anxiety and depression but with some differences in how these are expressed for each symptom type. Difficulties in threat-safety cue discrimination characterise anxiety and are understudied in depression, while biases in the retrieval of negative and overgeneral memories have been observed in depression but are understudied in anxiety. Information-processing biases have been studied in relation to some distal factors but not systematically, so relationships remain inconclusive. Biases in attention, threat-safety cue discrimination, memory and appraisal may characterise anxiety and/or depression risk. We discuss future research directions that can more systematically test whether these biases act as proximal mechanisms that mediate other distal risk factors. © 2016 The Authors.

We sought to evaluate the psychometric properties of two widely used screening scales: the Patient Health Questionnaire (PHQ-9) and Edinburgh Postnatal Depression Scale (EPDS) among pregnant Peruvian women. This cross-sectional study included 1517 women receiving prenatal care from February 2012 to March 2013. A structured interview was used to collect data using PHQ-9 and EPDS. We examined reliability, construct and concurrent validity between two scales using internal consistency indices, factor structures, correlations, and Cohen׳s kappa. Both scales had good internal consistency (Cronbach׳s alpha>0.8). Correlation between PHQ-9 and EPDS scores was fair (rho=0.52). Based on exploratory factor analysis (EFA), both scales yielded a two-factor structure. EFA including all items from PHQ-9 and EPDS yielded four factors, namely, "somatization", "depression and suicidal ideation", "anxiety and depression", and "anhedonia". The agreement between the two scales was generally fair at different cutoff scores with the highest Cohen׳s kappa being 0.46. Both the PHQ-9 and EPDS are reliable and valid scales for antepartum depression assessment. The PHQ-9 captures somatic symptoms, while EPDS detects depressive symptoms comorbid with anxiety during early pregnancy. Our findings suggest simultaneous administration of both scales may improve identification of antepartum depressive disorders in clinical settings. Copyright © 2014 Elsevier B.V.

It is well known that some lifestyle factors are related to depression, but their cumulative contribution to the depression remains unclear. This study aimed to assess the importance of multiple lifestyle factors in contributing to depressive symptoms among Chinese college students. Between September and December in 2012, we conducted a cross-sectional study among 1907 Chinese college students from Guangzhou, Southern China. College students completed self-administered questionnaires and reported their lifestyle factors including sleep quality and duration, Internet use, smoking, drinking, exercise, outdoor activity or sunlight exposure, and eating breakfast. Depression was measured using the Center for Epidemiologic Studies Depression Scale (CES-D), and mild-to-moderate depressive symptoms were defined as the CES-D score ≥16. Among all the students, 29.7% reported mild-to-moderate depressive symptoms. Higher quality and longer duration of sleep, more exercises, more outdoor activities or sunlight exposures, and eating breakfast daily were associated with a lower CES-D score, which could explain 11.3% of variance of the CES-D score, after adjusting for socio-demographics, family history, interpersonal relationship, and academic characteristics using hierarchical multivariable linear regression. These associations were comparable between males and females. The protective role of healthy lifestyles should be considered in intervention programs for improving mental health among college students. Copyright © 2016 Elsevier Ireland Ltd.

Data-driven subtypes of major depressive disorder: a systematic review

PubMed Central

2012-01-01

Background According to current classification systems, patients with major depressive disorder (MDD) may have very different combinations of symptoms. This symptomatic diversity hinders the progress of research into the causal mechanisms and treatment allocation. Theoretically founded subtypes of depression such as atypical, psychotic, and melancholic depression have limited clinical applicability. Data-driven analyses of symptom dimensions or subtypes of depression are scarce. In this systematic review, we examine the evidence for the existence of data-driven symptomatic subtypes of depression. Methods We undertook a systematic literature search of MEDLINE, PsycINFO and Embase in May 2012. We included studies analyzing the depression criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) of adults with MDD in latent variable analyses. Results In total, 1176 articles were retrieved, of which 20 satisfied the inclusion criteria. These reports described a total of 34 latent variable analyses: 6 confirmatory factor analyses, 6 exploratory factor analyses, 12 principal component analyses, and 10 latent class analyses. The latent class techniques distinguished 2 to 5 classes, which mainly reflected subgroups with different overall severity: 62 of 71 significant differences on symptom level were congruent with a latent class solution reflecting severity. The latent class techniques did not consistently identify specific symptom clusters. Latent factor techniques mostly found a factor explaining the variance in the symptoms depressed mood and interest loss (11 of 13 analyses), often complemented by psychomotor retardation or fatigue (8 of 11 analyses). However, differences in found factors and classes were substantial. Conclusions The studies performed to date do not provide conclusive evidence for the existence of depressive symptom dimensions or symptomatic subtypes. The wide diversity of identified factors and classes might result either from the absence of patterns to be found, or from the theoretical and modeling choices preceding analysis. PMID:23210727

Depressive disorders and symptoms are common among middle-aged women. The effects of hormones on depression remain unclear. This review aims to clarify the nature of depressive disorders during the menopause transition as well as their links with climacteric syndrome, sexuality, cardiovascular risk and cognitive function. The recent literature on depressive disorders and menopause is reviewed. Women are more vulnerable than men to depressive disorders. Endocrine influences have been postulated but differences in, for example, coping style and response to stress may also contribute to the gender difference in the prevalence of depressive disorders. Gender differences in socialization may lead to higher rates of depression in women. There are data top suggest that menopause and depression are associated, although there is not a common clear causative factor. Women with climacteric symptoms (hot flushes, night sweats, vaginal dryness and dyspareunia) are more likely to report anxiety and/or depressive symptoms. Bothersome vasomotor symptoms could be associated with sleep disturbances, which in turn can increase reports of anxiety and depressive symptoms. Biopsychosocial and partner factors have a significant influence on middle-aged women's sexuality and depressive disorders, and most antidepressants can have a negative effect on sexual response. Lastly, studies have consistently shown that women with high levels of depressive symptoms are at greater cardiovascular risk and have poorer cognitive function than non-depressed women. At present, a direct relationship between psychiatric symptoms and hormonal changes such as estrogen decrease has not been clearly found. Stress, educational level, ethnicity, socioeconomic factors and partner status may influence the prevalence and clinical course of both menopause symptoms and depressive disorders. Since in many cases depression is a lifelong condition, and is associated with severe comorbid conditions, further studies are needed to improve the early diagnosis of depression; it may be advisable to monitor a woman's mental health during the menopause transition to prevent a depressive disorder having long-term negative consequences.

Depression is common among individuals with osteoarthritis and leads to increased healthcare burden. The objective of this study was to examine excess total healthcare expenditures associated with depression among individuals with osteoarthritis in the US. Adults with self-reported osteoarthritis (n = 1881) were identified using data from the 2010 Medical Expenditure Panel Survey (MEPS). Among those with osteoarthritis, chi-square tests and ordinary least square regressions (OLS) were used to examine differences in healthcare expenditures between those with and without depression. Post-regression linear decomposition technique was used to estimate the relative contribution of different constructs of the Anderson's behavioral model, i.e., predisposing, enabling, need, personal healthcare practices, and external environment factors, to the excess expenditures associated with depression among individuals with osteoarthritis. All analysis accounted for the complex survey design of MEPS. Depression coexisted among 20.6 % of adults with osteoarthritis. The average total healthcare expenditures were $13,684 among adults with depression compared to $9284 among those without depression. Multivariable OLS regression revealed that adults with depression had 38.8 % higher healthcare expenditures (p < 0.001) compared to those without depression. Post-regression linear decomposition analysis indicated that 50 % of differences in expenditures among adults with and without depression can be explained by differences in need factors. Among individuals with coexisting osteoarthritis and depression, excess healthcare expenditures associated with depression were mainly due to comorbid anxiety, chronic conditions and poor health status. These expenditures may potentially be reduced by providing timely intervention for need factors or by providing care under a collaborative care model.

Shorter sleep time was reported to be associated with psychological functioning in children. We intended to examine the relationship between nocturnal sleep duration and depression status by investigating if delayed bedtime could be one of the enhancement factors for depression in children. A cross-sectional study was performed to investigate the depression status in elementary school children in middle Taiwan. Total 676 participants from 29 schools, in grades 3-6 were recruited to participate in the study. A modified depression scale for domestic school children was used to determine the depression status. Data of depression-related demographic characteristics, family, school variables and bedtime data were collected with a structured questionnaire. The results showed that almost one in five children (18%) had depression status. Delayed bedtime, child-parent relationship, family climate, and peer relationship were found to be the main predictors of childhood depression. Further stratification analysis showed that delayed bedtime significantly interacted with family climate and peer relationship on childhood depression. The risk of depression for children with a delayed bedtime of 10 PM and either in a non-harmonious family life or without a close parent-child relationship was 4.35 and 4.73 times greater than the reference group respectively. This study provides evidence for interactive effects between delayed bedtime and family concern factors which synergistically elevated the risk of childhood depression. This information may serve as a practical guide for parents and school teachers by recognizing that an adequate bedtime schedule could serve as a preventive measure against depression in children.

In a framework of search for early predictors of depression in patients with ischemic heart disease (IHD) we studied effect of molecular-genetic factors (polymorphism of brain-derived neirotrophic factor--BDNF), personality traits (anxiety, neuroticism), IHD severity, and psychosocial stressors on manifestations of depression in men with verified diagnosis of IHD. Severity of depression was assessed by Hamilton Depression Rating Scale 21-item (HAMD 21), anxiety and neuroticism were evaluated by the Spielberger State-Trait Anxiety Inventory and "Big Five" questionnaire, respectively. It wa shown that personal anxiety and ValVal genotype of BDNF gene appeared to be predictors of moderate and severe depression.

This study examined the psychometric qualities of the Center for Epidemiologic Studies-Depression scale (CES-D) in Jordanian women. Cronbach's alpha for the 20-item CES-D was .90. Factor analysis yielded three components. Four of the items had poor factor loadings and, therefore, were dropped. Cronbach's alpha for the remaining 16 items was .85. Validity testing using independent samples t-test provided evidence of discriminant validity for the 20-item and the 16-item CES-D. Attributes of the CES-D items indicated that depression status can be easily identified by clinicians. Co morbidity of depressive symptoms with physical and mental problems necessitates routine screening for depressed mood.

What are the causes of late-life depression?

Aziz, Rehan; Steffens, David C

2013-12-01

Although depression in old age is less common than depression in younger populations, it still affects more than 1 million community-living older adults. Depression in late life has been associated with reduced quality of life and increased mortality from both suicide and illness. Its causes are multifactorial but are prominently related to both biologic and social factors. Psychological factors, although less studied in elders, are also important in understanding its cause. In this article, multiple facets of late-life depression are reviewed, including its clinical presentation, epidemiology, and biopsychosocial causes. Copyright © 2013 Elsevier Inc.

Prenatal depression (PD) as a risk factor for adverse birth outcomes is well documented. Less is known about maternal risks for PD, which could inform preventive strategies for perinatal and interconceptional care. This exploratory study investigates associations between prenatal depression symptoms and unintended and mistimed pregnancies and other maternal risk factors for PD. A subset of birth records from the New York Statewide Perinatal Data System (n = 19,219) was used in this secondary analysis of cross-sectional data. Univariate and multivariate multinomial regression was used to identify factors that are independently associated with four self-reported levels of prenatal depression symptoms. Women with unintended pregnancies were more likely (AOR, 95 % CI) to report severe (3.6, 2.6-5.1) or moderate (2.0, 1.6-2.5) prenatal depression symptoms and less likely to report no symptoms, compared to women with intended pregnancies. Likewise, women with mistimed pregnancies were more likely to report severe (2.7, 2.2-3.5) or moderate (1.7, 1.5-2.1) prenatal depression symptoms than no symptoms, compared to women with intended pregnancies. Low education, drug use, smoking, minority race, being unmarried and having Medicaid insurance were also significant, independent predictors of PD symptoms. Results suggest that routine screening for depression, intendedness of pregnancy and other associated risk factors such as smoking and drug use during prenatal and interconceptional care visits may enable coordinated interventions that can reduce prenatal depression and unintended and mistimed pregnancies and improve pregnancy outcomes.

Depression is a common co-morbid health problem in patients with diabetes that is underrecognised. Current international guidelines recommend screening for depression in patients with diabetes. Yet, few depression screening instruments have been validated for use in this particular group of patients. Aim of the present study was to investigate the psychometric properties of the Turkish version of the Centre for Epidemiologic Studies Depression Scale (CES-D) in patients with type 2 diabetes. A sample of 151 Turkish outpatients with type 2 diabetes completed the CES-D, the World Health Organization-Five Well-Being Index (WHO-5), and the Problem Areas in Diabetes scale (PAID). Explanatory factor analyses, various correlations and Cronbach's alpha were investigated to test the validity and reliability of the CES-D in Turkish diabetes outpatients. The original four-factor structure proposed by Radloff was not confirmed. Explanatory factor analyses revealed a two-factor structure representing two subscales: (1) depressed mood combined with somatic symptoms of depression and (2) positive affect. However, one item showed insufficient factor loadings. Cronbach's alpha of the total score was high (0.88), as were split-half coefficients (0.77-0.90). The correlation of the CES-D with the WHO-5 was the strongest (r = -0.70), and supported concurrent validity. The CES-D appears to be a valid measure for the assessment of depression in Turkish diabetes patients. Future studies should investigate its sensitivity and specificity as well as test-retest reliability.

Risk factors for suicide completion in major depression: a case-control study of impulsive and aggressive behaviors in men.

Major depression is a major risk factor for suicide. However, not all individuals with major depression commit suicide. Impulsive and aggressive behaviors have been proposed as risk factors for suicide, but it remains unclear whether their effect on the risk of suicide is at least partly explained by axis I disorders commonly associated with suicide, such as major depression. With a case-control design, a comparison of the level of impulsive and aggressive behaviors and the prevalence of associated psychopathology was carried out with control for the presence of primary psychopathology. One hundred and four male suicide completers who died during an episode of major depression and 74 living depressed male comparison subjects were investigated with proxy-based interviews by using structured diagnostic instruments and personality trait assessments. The authors found that current (6-month prevalence) alcohol abuse/dependence, current drug abuse/dependence, and cluster B personality disorders increased the risk of suicide in individuals with major depression. Also, higher levels of impulsivity and aggression were associated with suicide. An analysis by age showed that these risk factors were more specific to younger suicide victims (ages 18-40). A multivariate analysis indicated that current alcohol abuse/dependence and cluster B personality disorder were two independent predictors of suicide. Impulsive-aggressive personality disorders and alcohol abuse/dependence were two independent predictors of suicide in major depression, and impulsive and aggressive behaviors seem to underlie these risk factors. A developmental hypothesis of suicidal behavior, with impulsive and aggressive behaviors as the starting point, is discussed.

To evaluate the relationships of depression and anxiety symptoms with cardiovascular disease (CVD) risk factors and measures of vascular health in youth. Major depressive disorder and bipolar disorder are considered CVD risk factors in youth. Participants (n = 202) were 8- to 18-year-olds from a cross-sectional study evaluating cardiovascular health across a wide range of body mass index values (normal weight to severe obesity). CVD risk measurement included blood pressure, fasting lipids, glucose, insulin, carotid artery intima-media thickness, compliance and distensibility, brachial artery flow-mediated dilation, carotid-radial artery pulse wave velocity, body fat percentage, and a metabolic syndrome cluster score. Anxiety and depression symptoms were self-reported on the Screen for Child Anxiety Related Disorders and Center for Epidemiological Studies Depression Scale for Children. Two sets of adjustment variables were used in evaluation of differences between those with and without anxiety or depression symptomatology for the CVD risk factor and vascular outcomes. The first set included adjustment for Tanner stage, sex, and race; the second was additionally adjusted for percent body fat. Anxiety was not significantly associated with CVD risk factors or vascular health in either model. Depression was associated with high-density lipoprotein cholesterol, triglycerides, and metabolic syndrome cluster score; these relationships were attenuated when accounting for percent body fat. When accounting for body fat, we found no clear relationship of self-reported depression or anxiety symptoms with CVD risk factors or vascular health in youth. Copyright © 2018 Elsevier Inc.

The Patient Health Questionnaire-9 (PHQ-9) is a widely used instrument for measuring levels of depression in patients in clinical practice and academic research; its factor structure has been investigated in various samples, with limited evidence of measurement equivalence/invariance (ME/I) but not in patients with more severe depression of long duration. This study aims to explore the factor structure of the PHQ-9 and the ME/I between treatment groups over time for these patients. 187 secondary care patients with persistent major depressive disorder (PMDD) were recruited to a randomised controlled trial (RCT) with allocation to either a specialist depression team arm or a general mental health arm; their PHQ-9 score was measured at baseline, 3, 6, 9 and 12 months. Exploratory Structural Equational Modelling (ESEM) was performed to examine the factor structure for this specific patient group. ME/I between treatment arm at and across follow-up time were further explored by means of multiple-group ESEM approach using the best-fitted factor structure. A two-factor structure was evidenced (somatic and affective factor). This two-factor structure had strong factorial invariance between the treatment groups at and across follow up times. Participants were largely white British in a RCT with 40% attrition potentially limiting the study's generalisability. Not all two-factor modelling criteria were met at every time-point. PHQ-9 has a two-factor structure for PMDD patients, with strong measurement invariance between treatment groups at and across follow-up time, demonstrating its validity for RCTs and prospective longitudinal studies in chronic moderate to severe depression.

The flux pinning properties in high temperature superconductors are strongly influenced by thermally activated flux motion. The scaling relation of the pinning force density and the irreversibility line in various high temperature superconductors are numerically analyzed in terms of the flux creep model. The effect of two factors, i.e., the flux pinning strength and the dimensionality of the material, on these properties are investigated. It is speculated that the irreversibility line in Bi-2212 superconductors is one order of magnitude smaller than that in Y-123, even if the flux pinning strength in Bi-2212 is improved up to the level of Y-123. It is concluded that these two factors are equally important in determination of the flux pinning characteristics at high temperatures.

Burnout and mental disorders have been reported in the financial industry. This study aims to examine the structural validity of the Maslach Burnout Inventory (MBI) and to investigate the connection between the dimensions of burnout and depressive symptoms in a sample of 1046 bank employees from North Brazil who completed the MBI and the Patient Health Questionnaire-9 (PHQ-9. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to cross-check the factorial structure of the MBI. One-way analysis of variance and correlation analysis were applied to elucidate the relationship between burnout and depressive symptoms. Both 3-factor and 4-factor oblique solutions were plausible EFA models of the burnout syndrome. Results of CFA supported the 19-item 4-factor structure as the best fitting model to data, with two exhaustion factors ("exhausted" and "strained"), depersonalization, and personal accomplishment. The PHQ-9 total score and individual score of depressive items were significantly correlated with all MBI dimensions, notably with the emotional exhaustion dimension. The moderate-to-high correlation observed between burnout and depression suggest the potential utility of the MBI for evaluating burnout among bank employees as well as to point out the need to evaluate systematically the burnout and depressive symptoms given to their potential association.

Depression is among the major causes of disability with a negative impact on both daily life and work performance. Whilst depression is the primary cause of sick-leave and unemployment in today's workplace there is a lack of knowledge of the needs of individuals with depression regarding their return-to-work (RTW) process. To explore which factors are of critical importance for people suffering from depression and who also are unemployed in their RTW-process and to explore the impact of two vocational approaches on the service users' experiences. The study included participants in two vocational rehabilitation approaches; Individual Enabling and Support (IES) and Traditional Vocational Rehabilitation (TVR). Qualitative methods were applied to explore critical factors in the RTW-process. Individuals with affective disorders including depression and bipolar disorder were included.RESULTSThree themes emerged as critical factors; Experiencing hope and power, Professionals' positive attitudes, beliefs and behaviours, and Employing a holistic perspective and integrating health and vocational service.CONCLUSIONThis study has demonstrated critical factors for the return-to-work process as experienced by persons with depression. To experience hope and power, to meet professionals that believe "you can work", who use a person-centred and holistic service approach, are such factors necessary for gaining a real job. In particular, professionals in TVR need to embrace this understanding since their services were not experienced as including these elements.

Depressive symptoms during adolescence are positively associated with peer-related beliefs, perceptions, and experiences that are known risk factors for substance misuse. These same risk factors are targeted by many universal substance misuse prevention programs. This study examined whether a multicomponent universal substance misuse intervention for middle schoolers reduced the associations between depressive symptoms, these risk factors, and substance misuse. The study used data from a place-randomized trial of the Promoting School-Community-University Partnerships to Enhance Resilience model for delivery of evidence-based substance misuse programs for middle schoolers. Three-level within-person regression models were applied to four waves of survey, and social network data from 636 adolescents followed from sixth through ninth grades. When adolescents in control school districts had more symptoms of depression, they believed more strongly that substance use had social benefits, perceived higher levels of substance misuse among their peers and friends, and had more friends who misused substances, although they were not more likely to use substances themselves. Many of the positive associations of depressive symptoms with peer-related risk factors were significantly weaker or not present among adolescents in intervention school districts. The Promoting School-Community-University Partnerships to Enhance Resilience interventions reduced the positive associations of adolescent symptoms of depression with peer-related risk factors for substance misuse.

The present study examines the risk of depression, suicidal ideation, and lower self-esteem following an abortion versus delivery, adjusting for important correlates. Using the National Comorbidity Survey, we examined how first pregnancy outcome (abortion versus delivery) related to subsequent major depression, suicidal ideation, and self-esteem. Models controlling for risk factors, such as background and economic factors, pre-pregnancy violence experience, and pre-pregnancy mental health, as well as a model with all risk factors, were examined. When no risk factors were entered in the model, women who had abortions were more likely to have subsequent depression (OR = 1.53, CI 1.05-2.22) and suicidal ideation (OR = 2.02, CI 1.40-2.92), but not more likely to have lower self-esteem (B = -.02). When all risk factors were entered, pregnancy outcome was not significantly related to later depression (OR = .87, CI .54-1.37) and suicidal ideation (OR = 1.19, CI .70-2.02); predictors of mental health following abortion and delivery included pre-pregnancy depression, suicidal ideation, and sexual violence. Policies and practices implemented in response to the claim that abortion hurts women are not supported by our findings. Efforts to support women’s mental health should focus on known risk factors, such as programs to address gender-based violence, rather than abortion history. PMID:21486261

Objectives Few prospective studies have examined personality and depression in older adults. We investigated whether the Five Factor Model (FFM) of personality traits --- Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness --- and trait combinations (styles) are related to incident major or minor depression. Participants/Setting Prospective data were gathered on a community sample of 512 older adults with disability and a history of significant health care utilization who were enrolled in a Medicare Demonstration Project. Measurements Depression and personality traits and styles were assessed at baseline; depression was assessed again at approximately 12 and 22 months. Design Participants who developed incident major depression were compared to those free of depression at all three assessments. Similar analyses were done for minor depression. Results High Neuroticism and low Conscientiousness were risk factors for both major and minor depression. Combinations of high Neuroticism with low or high Extraversion or high Openness conferred risk for major depression. Other novel findings for major depression revealed new trait combinations of low Conscientiousness with low or high Extraversion, high Openness, or low Agreeableness. Three trait combinations, all involving low Conscientiousness, predicted risk for minor depression: high Neuroticism, high Agreeableness, and low Openness. Conclusion The present findings highlight the importance of examining combinations of personality traits or personality styles when identifying those who are most at-risk for geriatric depression. Since other personality domains may modify the risk related to high Neuroticism and low Conscientiousness, the prevention, diagnosis, and treatment of depression could be greatly improved by assessing older patients not only on all five domains of personality but in terms of their combinations.

Early-onset depressive disorders can have severe consequences both from developmental and functional aspects. The etiology of depressive disorders is complex and multi-factorial, with an intricate interaction among environmental factors and genetic predisposition. While data from studies on adults suggest that caffeine is fairly safe, effects of caffeine in children, who are in period of rapid brain development, are currently unknown. Furthermore, systematic research addressing the relationship between depressive symptoms in children and caffeine consumption is lacking.The present study examined the effects of caffeine consumption on depressed mood in children with depression and non-depressed participants. Children and adolescents (n = 51) already enrolled in an ongoing longitudinal study, aged 9-12 years, were assessed for depressive symptoms with the Children Depressive Inventory (CDI). Psychopathological symptoms were assessed with the Child Behavioral Checklist (CBCL) and eating habits were assessed with the Nutrition-Behavior Inventory (NBI) 1. The children were compared to control children without psychopathology attending public schools in a Southern Brazilian city. Participants with CDI scores ≥ 15 (mean = 19; S.D. = 4) also had high NBI scores (mean = 52; S.D. = 19, p < 0.001) suggestive of a relationship between depressive symptoms and environmental factors, in this case nutrition/behavior. Additional linear regression adjusted statistical analysis, considering the factors of consumption of sweets and caffeine individually, showed that caffeine, but not sweets, was associated with depressive symptoms. These findings indicate that depressed children consume more caffeinated drinks than non-depressed children. Nonetheless while a strong association between depressive symptoms and caffeine consumption among children was found, further research should investigate whether or not this association is due to a cause and effect relationship.

While data from studies on adults suggest that caffeine is fairly safe, effects of caffeine in children, who are in period of rapid brain development, are currently unknown. Furthermore, systematic research addressing the relationship between depressive symptoms in children and caffeine consumption is lacking. The present study examined the effects of caffeine consumption on depressed mood in children with depression and non-depressed participants. Methods Children and adolescents (n = 51) already enrolled in an ongoing longitudinal study, aged 9-12 years, were assessed for depressive symptoms with the Children Depressive Inventory (CDI). Psychopathological symptoms were assessed with the Child Behavioral Checklist (CBCL) and eating habits were assessed with the Nutrition-Behavior Inventory (NBI) [1]. The children were compared to control children without psychopathology attending public schools in a Southern Brazilian city. Results Participants with CDI scores ≥ 15 (mean = 19; S.D. = 4) also had high NBI scores (mean = 52; S.D. = 19, p < 0.001) suggestive of a relationship between depressive symptoms and environmental factors, in this case nutrition/behavior. Additional linear regression adjusted statistical analysis, considering the factors of consumption of sweets and caffeine individually, showed that caffeine, but not sweets, was associated with depressive symptoms. Conclusions These findings indicate that depressed children consume more caffeinated drinks than non-depressed children. Nonetheless while a strong association between depressive symptoms and caffeine consumption among children was found, further research should investigate whether or not this association is due to a cause and effect relationship.

To assess the concurrent and the construct validity of the Euro-D in older Thai persons. Eight local psychiatrists used the major depressive episode section of the Mini International Neuropsychiatric Interview to interview 150 consecutive psychiatric clinic attendees. A trained interviewer administered the Euro-D. We used receiver operating characteristic (ROC) analysis to assess the overall discriminability of the Euro-D scale and principal components factor analysis to assess its construct validity. The area under the ROC curve for the Euro-D with respect to major depressive episode was 0.78 [95% confidence interval (CI) 0.70-0.90] indicating moderately good discriminability. At a cut-point of 5/6 the sensitivity for major depressive episodes is 84.3%, specificity 58.6%, and kappa 0.37 (95% CI 0.22-0.52) indicating fair concordance. However, at the 3/4 cut-point recommended from European studies there is high sensitivity (94%) but poor specificity (34%). The principal components analysis suggested four factors. The first two factors conformed to affective suffering (depression, suicidality and tearfulness) and motivation (interest, concentration and enjoyment). Sleep and appetite constituted a separate factor, whereas pessimism loaded on its own factor. Among Thai psychiatric clinic attendees Euro-D is moderately valid for major depression. A much higher cut-point may be required than that which is usually advocated. The Thai version also shares two common factors as reported from most of previous studies.

To identify viewpoints among men with depression about depression and its treatment, consider how these might influence help-seeking behaviour, and generate ideas for interventions and future research. Q methodology. Twenty-nine men with depression completed a Q sort by ranking a set of statements about depression and help-seeking according to their relative agreement with each statement. Factor analysis was used to identify viewpoints relating to male understandings of depression and help-seeking, which were interpreted in the context of participant characteristics and additional information from post-sorting interviews. A two-factor solution accounting for 45% of the total variance was considered the best fit for the data. The 2 factors were: (1) Help is available if you can get to the point of asking for it (34% of the variance) and (2) depression should be dealt with in private; help-seeking makes you vulnerable (11% of the variance). Participants who were significantly associated with both factors described a sense of shame, relating to their own or others' views that being depressed and help-seeking are in conflict with socially constructed 'masculine' values, such as strength and self-sufficiency. In the viewpoint represented by Factor 1, however, the benefits of help-seeking outweigh the negatives. In contrast, the viewpoint represented in Factor 2 holds that depression should remain a private struggle and that help-seeking is too risky a move to make. In order to access treatment, men must first recognize depression, then overcome considerable perceived and internalized stigma to ask for help. Improving public knowledge about the nature of depression; positive messages about the act of help-seeking, types of treatment available, and effectiveness of treatments; and work to overcome the challenges posed by long waiting times and other service constraints may increase rates of help-seeking, and represent areas for future research. Interventions to improve recognition of depression symptoms, particularly in the absence of recent negative life events or suicidal ideation, might help to improve help-seeking rates among men. Media campaigns should consider focusing on the positive elements of help-seeking and potential for recovery, and the impact of such campaigns should be evaluated. Improving public knowledge of the types of non-medical intervention that are available for depression may help to increase help-seeking rates. Clinical services and commissioners should be aware of the impact of long waiting times and strict discharge policies on service users, especially those who have difficulty asking for help. © 2017 The British Psychological Society.

This study investigated the prevailing rate of depression in female marriage immigrants in Korea and the predictive factors of their rates of depression. The study included 316 foreign female marriage immigrant participants. Four instruments yielded the data: the Center for Epidemiologic Studies Depression Scale and Multidimensional Scale of Perceived Social Support and questionnaires regarding the participants' Korean language ability and demographic data. The survey scales were translated into Korean, Vietnamese, Chinese, and English. The data collection was conducted by a face-to-face interview and translators were used when needed. The female marriage immigrants were found to have higher depression rates than women in the general Korean population. The predictive factors of depression for the female marriage immigrants included their country of origin, Korean speaking ability, and family support. Far more depression was found to occur in the Chinese participants, while the rate of depression was lower in those with competent Korean speaking ability and family support. An exploration of strategies to improve the speaking ability and family support of female marriage immigrants will be necessary in order to decrease their incidence of depression and the strategies should be differentiated based on the female marriage immigrants' country of origin. © 2011 Blackwell Publishing Asia Pty Ltd.

Prevalence and Associated Factors of Depressive Symptoms among Chinese Underground Coal Miners

Although underground coal miners are quite susceptible to depressive symptoms due to a highly risky and stressful working environment, few studies have focused on this issue. The purpose of the study was to evaluate the prevalence of depressive symptoms and to explore its associated factors in this population. A cross-sectional survey was conducted in a coal-mining population in northeast China. A set of self-administered questionnaires was distributed to 2500 underground coal miners (1,936 effective respondents). Depressive symptoms, effort-reward imbalance (ERI), overcommitment (OC), perceived physical environment (PPE), work-family conflict (WFC), and some demographic and working characteristics were measured anonymously. The prevalence of depressive symptoms was 62.8%, and the mean level was 20.00 (9.99). Hierarchical linear regression showed that marital status, education, monthly income, and weekly working time were significantly associated with depressive symptoms. A high level of depressive symptoms was significantly associated with high ERI, PPE, WFC, and OC. Accordingly, most Chinese underground coal miners probably have depressive symptoms that are mainly predicted by some occupational psychosocial factors. Efforts should be made to develop strategies to reduce ERI and OC, improve physical working environment, and care for workers' family well-being, thereby mitigating the risk of depression among Chinese underground coal miners.

Previous studies have shown that various factors, such as genetic and environmental factors, contribute to the development of major depressive disorder (MDD). The aim of this study is to clarify how multiple factors, including affective temperaments, childhood abuse and adult life events, are involved in the severity of depressive symptoms in MDD. A total of 98 participants with MDD were studied using the following self-administered questionnaire surveys: Patient Health Questionnaire-9 measuring the severity of depressive symptoms; Life Experiences Survey (LES) measuring negative and positive adult life events; Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego auto-questionnaire (TEMPS-A) measuring affective temperaments; and the Child Abuse and Trauma Scale (CATS) measuring childhood abuse. The data were analyzed using single and multiple regression analyses and structural equation modeling (SEM). The neglect score reported by CATS indirectly predicted the severity of depressive symptoms through affective temperaments measured by TEMPS-A in SEM. Four temperaments (depressive, cyclothymic, irritable, and anxious) directly predicted the severity of depressive symptoms. The negative change in the LES score also directly predicted severity. This study suggests that childhood abuse, especially neglect, indirectly increases the severity of depressive symptoms through increased scores of affective temperaments in MDD.

Neurotrophic factors have been implicated in neuropsychiatric disorders, including schizophrenia and depression. Glial Cell Line-Derived Neurotrophic Factor (GDNF) promotes development, differentiation, and protection of dopaminergic, serotonergic, GABAergic and noradrenergic neurons as well as glial cells in different brain regions. This study examined serum levels of GDNF in schizophrenia and depression and its correlation with metabolic parameters during 8 weeks of treatment. Serum GDNF level, fasting serum glucose and lipid profile were measured at baseline and week 8 in 133 women: 55 with schizophrenia, 30 with a first episode depression and 48 healthy controls. The severity of the symptoms was evaluated using Positive and Negative Syndrome Scale (PANSS), 17-item Hamilton Depression Rating Scale (HDRS) and Beck Depression Inventory (BDI). There was statistically significant higher GDNF level in schizophrenia at baseline when compared with week 8. Correlations of GDNF with PANSS in schizophrenia and cholesterol level in depression have also been detected. To our knowledge, this is the first study which correlates GDNF levels with metabolic parameters. Our results show no differences in GDNF serum level between schizophrenia, a first depressive episode, and healthy controls. GDNF serum level did not correlate with metabolic parameters except for total cholesterol in depression. Copyright © 2017 Elsevier B.V. All rights reserved.

This study describes prevalence of depressive and anxious symptoms together with family, environmental and personal risk factors in a group of adolescents between 14 and 18 years of age in a private school of Medellín. An analytic observational cross sectional study was performed in 152 adolescents, evaluating sociodemographic aspects and prevalence of depressive and anxious symptomatology, as established through BDI-II and BAI. Average age was 15.4 ± 0.9 years old, with a 25% prevalence of anxiety symptoms and 25.7% of depressive symptoms. From the 38 (25%) students with BAI positive, 26 (68.4%) were BDI positive, and from the 39 (25.6%) students with BDI positive, 26 (66.7%) were BAI positive. the risk factors for anxiety and depressive symptomatology were: being a woman, being a victim of bullying and abuse. Having friends was the protective factors for depressive symptomatology. There was a statistical association between self-report of depressive and anxiety symptomatology; between the anxiety self-report and the depressive symptomatology; as well as between depressive and anxiety symptomatology and parents' perception of such symptoms.

Anxiety and depression are prevalent during pregnancy. Estimates of the prevalence of anxiety and depression during pregnancy vary according to the criteria used, variable methodologies and population characteristics. A cross-sectional survey design was used. A total of 175 antenatal mothers participated. Their socio-demographic and obstetric histories were recorded. The Hospital Anxiety and Depression Scale (HADS) and Mini International Neuropsychiatric Interview (M.I.N.I.) were used. The prevalence of anxiety and depression disorders among antenatal mothers using diagnostic clinical interview were 9.1% and 8.6%, respectively. Factors associated with antenatal anxiety were marital status (being unmarried), positive history of mental illness, gestational age (<20 weeks), unplanned pregnancy and depressive comorbidity. However, only gestational age of less than 20 weeks and depressive disorder remained significant factors in the multivariate analysis. The prevalence rate of antenatal depression detected by HADS screening was comparable to the rate from diagnostic interview, but there was a slight overestimation for antenatal anxiety. Nonetheless, HADS as a screening tool offers a practical solution for detecting these two conditions in a busy antenatal clinic or a large epidemiological survey. In view of the deleterious effects of antenatal anxiety and depression on mothers and children, these two conditions should be screened and managed appropriately.

Identifying depressive cognitions in Brazilians with diabetes can be important step to prevent the development of clinical depression, which is negatively associated with diabetes self-management. This study focused on the psychometric testing of the Portuguese version of the Depressive Cognition Scale, the Escala Cognitiva de Depressão (ECD), among 82 Brazilian adults with diabetes mellitus. The questionnaire was assessed for internal consistency, homogeneity, and construct validity using factor analysis and convergent validity assessment with the Portuguese version of the Beck Depression Inventory, the Inventário de Depressão Beck (IDB). Cronbach's alpha for the ECD was .88. The homogeneity of the instrument was supported by item-to-total correlations between .30 and .70. Factor extraction generated only one factor with eigenvalues greater than 1, which is consistent with the English version. The ECD's total score had a weak but significant correlation with the IDB's total score (r = .24, p < .05), indicating convergent validity. Evidence for the reliability and construct validity of the ECD was provided by this study. This scale has the potential to become a useful screening tool for depressive cognitions among Brazilians with diabetes.

To examine key determinants of anxiety and depression in a community sample of people with epilepsy. Data were analyzed from the 2010 Australian Epilepsy Longitudinal Survey, examining living with epilepsy in Australia. The HADS was analyzed, and Pearson correlations and block recursive regression were undertaken to identify key associations between anxiety, depression, and a range of variables and to identify key determinants of anxiety and depression. Key factors to influence anxiety were social aspects of stigma, effectiveness of seizure control, whether in employment, and the number of different epilepsy drugs. Determinants for depression were social aspects of stigma, whether in employment, and the effectiveness of seizure control. Stigma was also found to be an important mediating variable for employment, control, and the number of drugs. Understanding the mechanisms involved in anxiety and depression in a community sample of people with epilepsy requires the inclusion of opportunities for paid employment and the effects of psychosocial factors such as stigma. Without this fuller social context, there are limitations on understanding factors that influence anxiety and depression and how to deal with the outcomes. Copyright © 2014 Elsevier Inc.

People living with HIV (PLWH) commonly report sleep disturbances which are associated with long-term health consequences, including disease progression. PLWH also experience internalised stigma as a result of their HIV status, which can be associated with increased loneliness and depression. Little attention focuses on the impact of these factors on sleep. Therefore, we examined whether internalised HIV-stigma was indirectly related to poorer sleep quality through higher levels of loneliness and depressive symptoms. 181 PLWH from across the United States completed an online survey. Main Study Measures: Internalised HIV-stigma was assessed using the HIV-Stigma Scale, loneliness was assessed using the UCLA-Loneliness Scale-Short Form, depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression Index, and Sleep Quality was assessed using the Pittsburgh Sleep Quality Index. Internalised HIV-stigma was indirectly associated with poorer global sleep quality and daytime sleep dysfunction through both loneliness and depressive symptoms. PLWH who experience HIV-related stigma may experience greater feelings of loneliness, which are related to increased depressive symptoms and poorer sleep quality. Interventions focused on improving sleep in PLWH should focus on multiple factors that influence sleep, including psychosocial factors such as stigma, social isolation and depressive symptoms.

Research in the field of factors associated with depression among adolescents is lacking in Malaysia. The aims of the present study were to assess the current prevalence of depression and its related factors among secondary school students in Pasir Gudang, South Malaysia. In this cross sectional study, 2,927 secondary school students (13-17 years old) from urban areas were screened for symptoms of mental disorder as well as demographic and risk behaviors using a validated Depression, Anxiety and Stress Scale (DASS) 12 questionnaire. The majority of the respondents (53.8%) were Malay, of which 53.1% were female. Symptoms of mild depression were found in 33.2% of the respondents, while the prevalence of the symptoms of moderate, severe, and extremely severe depression was 21.5%, 18.1%, and 3.0%, respectively. Logistic regression suggested that participants who were Chinese or had a lower average grade were three times more likely to have depression, while those who came from a single-parent family were twice as likely to have this condition. This study indicated that academic performance and risk behaviors along with the demographic characteristics are important contributors to adolescent depression.

The psychometric properties of the Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995a) were examined in depressed psychiatric hospital samples. Three studies administered the DASS and other symptom measures at admission and discharge to consecutive adult hospital patients with a primary diagnosis of depression. Study 3 aimed to address problems with the DASS by extending the response options. Study 1 found that the DASS had good reliability and validity, was moderately sensitive to change, but the Depression Scale exhibited a ceiling effect. In Study 2, confirmatory factor analysis supported a three-factor structure and the DASS continued to demonstrate good psychometric properties, but the ceiling effect was replicated. Study 3 found that by extending the response scale to include an additional option, the factor structure of the instrument as a whole was maintained, the sensitivity to treatment was increased, but the ceiling effect was only marginally reduced. The psychometric properties of the DASS were sound in clinically depressed samples, but the Depression Scale exhibited a ceiling effect that could not be resolved with minor changes to the scale. Suggestions for revisions of the DASS are made.

Antenatal depression.

About 20 per cent of pregnant women experience antenatal depression (AD), which not only has deleterious effects on the woman and her baby but also increases the risk of developing postpartum depression. Nurses who understand the prevalence, signs and symptoms, and risk factors associated with AD can help to identify it and prevent the sequelae. The signs and symptoms of depression in pregnancy do not differ from depression at at any other time. However, AD may go undiagnosed because of a focus on maternal and fetal well-being and the attribution of complaints to the physical and hormonal changes associated with pregnancy. Risk factors include history of depression, lack of partner, marital difficulties, lack of social support, poverty, family violence, increased life stress, substance abuse, history of previous abortions, unplanned pregnancy, ambivalence toward the pregnancy and anxiety about the fetus. Most of the standard treatments for depression can be used in pregnant women, with the exception of some antidepressant medications. Supportive therapies--exercise, adequate nutrition, adequate sleep, and support from family and friends--are also indicated. Screening of women with known risk factors is crucial, but the authors suggest that the high overall prevalence of depressive symptoms during pregnancy indicates a need for universal screening.

OBJECTIVE To estimate the prevalence of depressive symptoms among institutionalized elderly individuals and to analyze factors associated with this condition. METHODS This was a cross-sectional study involving 462 individuals aged 60 or older, residents in long stay institutions in four Brazilian municipalities. The dependent variable was assessed using the 15-item Geriatric Depression Scale. Poisson’s regression was used to evaluate associations with co-variables. We investigated which variables were most relevant in terms of presence of depressive symptoms within the studied context through factor analysis. RESULTS Prevalence of depressive symptoms was 48.7%. The variables associated with depressive symptoms were: regular/bad/very bad self-rated health; comorbidities; hospitalizations; and lack of friends in the institution. Five components accounted for 49.2% of total variance of the sample: functioning, social support, sensory deficiency, institutionalization and health conditions. In the factor analysis, functionality and social support were the components which explained a large part of observed variance. CONCLUSIONS A high prevalence of depressive symptoms, with significant variation in distribution, was observed. Such results emphasize the importance of health conditions and functioning for institutionalized older individuals developing depression. They also point to the importance of providing opportunities for interaction among institutionalized individuals. PMID:24897042

Traditionally, Typus melancholicus (TM) was considered, a priori, to represent unidimensionality. Recent studies have suggested that TM is not a personality trait, but rather a constellation of personality traits. The purpose of this study was to examine whether TM on Kasahara's Inventory for the Melancholic Type Personality (KIMTP), considered to represent one of the valid TM questionnaires, is comprised of personality dimensions, and if so, which dimension is essential for distinguishing depressive subjects from control subjects. To clarify the dimensionality of TM scores on KIMTP, factor analysis of the TM scores was conducted using principal factor analysis followed by varimax rotation. Comparisons were then made between endogenous depressive patients (n = 38), nonendogenous depressive patients (n = 20), and healthy volunteers (n = 81) for total KIMTP score and factor scores using analysis of covariance, adjusting for sex and age. Factor analysis of KIMTP revealed 2 distinct clusters of items, i.e. 'harmony in personal relationships' (factor 1) and 'social norms' (factor 2). Endogenous and nonendogenous depressive patients showed significantly higher KIMTP total and factor 1 scores than did control subjects. However, no significant differences were observed for KIMTP total score and scores of individual factors between endogenous and nonendogenous depressive patients. The present results indicate that TM on KIMTP represents a constellation of personality traits, and that the factor 'harmony in personal relationship' possesses the essential meaning for assessing TM.

This study prospectively examined the course of depression in African American and Caucasian midlife women over an 11-year period. Racial differences in lifetime history of depression, severity of depressive symptoms and rates of depressive disorders at baseline, and persistence or recurrence of depression over an 11 year period were examined. Predictors of persistence/recurrence of depression were also examined. The sample was comprised of 423 midlife women enrolled in the Study of Women Across the Nation (SWAN) Mental Health Study (MHS). All participants completed baseline and annual assessments, which included self-reported measures of health, functioning, and psychosocial factors, and clinician administered assessments of psychiatric disorders. Logistic regression analyses were used to examine predictors of depression persistence/recurrence. Findings indicated that African American and Caucasian women did not differ significantly in rates of lifetime and baseline depressive disorders, or severity of depressive symptoms. Annual assessments revealed no significant differences between the groups in rates of persistent/recurrent depression. While African American and Caucasian women do not differ in recurrence of depression at midlife, factors associated with depression differed by race.

Many factors have been associated with the onset and maintenance of depressive symptoms in later life, although this knowledge is yet to be translated into significant health gains for the population. This study gathered information about common modifiable and non-modifiable risk factors for depression with the aim of developing a practical probabilistic model of depression that can be used to guide risk reduction strategies. A cross-sectional study was undertaken of 20,677 community-dwelling Australians aged 60 years or over in contact with their general practitioner during the preceding 12 months. Prevalent depression (minor or major) according to the Patient Health Questionnaire (PHQ-9) assessment was the main outcome of interest. Other measured exposures included self-reported age, gender, education, loss of mother or father before age 15 years, physical or sexual abuse before age 15 years, marital status, financial stress, social support, smoking and alcohol use, physical activity, obesity, diabetes, hypertension, and prevalent cardiovascular diseases, chronic respiratory diseases and cancer. The mean age of participants was 71.7 ± 7.6 years and 57.9% were women. Depression was present in 1665 (8.0%) of our subjects. Multivariate logistic regression showed depression was independently associated with age older than 75 years, childhood adverse experiences, adverse lifestyle practices (smoking, risk alcohol use, physical inactivity), intermediate health hazards (obesity, diabetes and hypertension), comorbid medical conditions (clinical history of coronary heart disease, stroke, asthma, chronic obstructive pulmonary disease, emphysema or cancers), and social or financial strain. We stratified the exposures to build a matrix that showed that the probability of depression increased progressively with the accumulation of risk factors, from less than 3% for those with no adverse factors to more than 80% for people reporting the maximum number of risk factors. Our probabilistic matrix can be used to estimate depression risk and to guide the introduction of risk reduction strategies. Future studies should now aim to clarify whether interventions designed to mitigate the impact of risk factors can change the prevalence and incidence of depression in later life.

Depression is common in patients with cardiometabolic diseases but little is known about the relationship, if any, between cardiovascular risk factor values and depressive symptoms in patients with these conditions. The objective of this paper is to study the association between cardiovascular risk factors and concurrent depressive symptoms in patients with three common cardiometabolic conditions: coronary heart disease (CHD), stroke and diabetes. We retrospectively reviewed primary care data for N = 35537 with 1 of the above 3 conditions who underwent depression screening using the depressive subscale of hospital anxiety and depression score (HADS-D). We reviewed 4 cardiometabolic risk factors (Systolic Blood Pressure [SBP], Diastolic Blood Pressure [DBP], BMI and total cholesterol) recorded concurrently in all patients and HbA1c in patients with diabetes (n = 18453). We analysed the association between individual risk factor value and a positive HADS-D screening result (>7) using logistic regression. SBP and BMI were noted to have a non-linear "J-shaped" relationship with the probability of having a positive HADS-D and observed nadirs (levels with the lowest probability) of 148 mm Hg and 30.70 kg/m2, respectively. Total cholesterol and DBP found to have a weaker curvilinear association with concurrent depression symptoms and nadirs of 3.60 mmol/l and 74 mmHg. Among patients with Diabetes, HbA1c was also found to have a "J-shaped" relationship with probability of having a positive HADS-D with an observed nadir of 7.06% DCCT. The above relationships remain significant after adjusting for age, sex, socio-economic status and number of co-morbid conditions. In patients with cardiometabolic disease, cardiovascular risk factor values at both extremes were associated with higher positive depression screening after adjusting for confounders. These findings have potentially important implications for clinical practice in relation to both risk stratification for depression and approaches to secondary prevention in individuals with cardiometabolic disease and merit further investigation to determine the nature and direction of the observed association.Please see related article: http://www.biomedcentral.com/1741-7015/12/199.

Research on adolescent depression has overwhelmingly focused on risk factors, such as stressful negative events and cognitive vulnerabilities, but much important information can be gained by focusing on protective factors. Thus, the current study aimed to broaden understanding on adolescent depression by considering the role of two positive elements as protective factors, attributional style for positive events and self-esteem, in a model of depression. The sample included 491 middle school students (52 % female; n = 249) with an age range from 12 to 15 years (M = 13.2, SD = .70). The sample was ethnically/racially diverse, with 55 % White, 22 % Hispanic, 10 % Asian American, 3 % African American, and 10 % Biracial/Other. Correlational analyses indicated significant cross-sectional and longitudinal associations between an enhancing attributional style (internal, stable, global attributions for positive events), self-esteem and depressive symptoms. Further, prospective analyses using bootstrapping methodology demonstrated significant indirect effects of an enhancing attributional style on decreases in depressive symptoms through its effects on self-esteem. These findings highlight the importance of considering attributional style for positive events as a protective factor in the developmental course of depressive symptoms during early adolescence.

Recent depression research has revealed a growing awareness of how to best classify depression into depressive subtypes. Appropriately subtyping depression can lead to identification of subtypes that are more responsive to current pharmacological treatment and aid in separating out depressed patients in which current antidepressants are not particularly effective. Differential co-expression analysis (DCEA) and differential regulation analysis (DRA) were applied to compare the transcriptomic profiles of peripheral blood lymphocytes from patients with two depressive subtypes: major depressive disorder (MDD) and subsyndromal symptomatic depression (SSD). Six differentially regulated genes (DRGs) (FOSL1, SRF, JUN, TFAP4, SOX9, and HLF) and 16 transcription factor-to-target differentially co-expressed gene links or pairs (TF2target DCLs) appear to be the key differential factors in MDD; in contrast, one DRG (PATZ1) and eight TF2target DCLs appear to be the key differential factors in SSD. There was no overlap between the MDD target genes and SSD target genes. Venlafaxine (Efexor™, Effexor™) appears to have a significant effect on the gene expression profile of MDD patients but no significant effect on the gene expression profile of SSD patients. DCEA and DRA revealed no apparent similarities between the differential regulatory processes underlying MDD and SSD. This bioinformatic analysis may provide novel insights that can support future antidepressant R&D efforts.

We examined the associations of emotional eating and depressive symptoms with the consumption of sweet and non-sweet energy-dense foods and vegetables/fruit, also focusing on the possible interplay between emotional eating and depressive symptoms. The participants were 25-64-year-old Finnish men (n=1679) and women (n=2035) from the FINRISK 2007 Study (DILGOM substudy). The Three-Factor Eating Questionnaire-R18, Center for Epidemiological Studies Depression Scale, and a 132-item Food Frequency Questionnaire were used. Emotional eating and depressive symptoms correlated positively (r=0.31 among men and women), and both were related to a higher body mass. Emotional eating was related to a higher consumption of sweet foods in both genders and non-sweet foods in men independently of depressive symptoms and restrained eating. The positive associations of depressive symptoms with sweet foods became non-significant after adjustment for emotional eating, but this was not the case for non-sweet foods. Depressive symptoms, but not emotional eating, were related to a lower consumption of vegetables/fruit. These findings suggest that emotional eating and depressive symptoms both affect unhealthy food choices. Emotional eating could be one factor explaining the association between depressive symptoms and consumption of sweet foods, while other factors may be more important with respect to non-sweet foods and vegetables/fruit.

2018-07-01

Depression amongst young people is a major health challenge and is often shaped by social marginalisation. Informal settlements are growing rapidly. There is a need to deepen understandings of depression amongst young people in these contexts. We sought to understand factors associated with depressive symptomology amongst 232 young people (122 women, 110 men) aged 18-30 in urban informal settlements in South Africa. We conducted a cross-sectional analysis of baseline data collected for the Stepping Stones and Creating Futures pilot. Logistic regression modelled relationships between depressive symptomology, livelihoods and violence. Symptomatic depression in this population was 49.5% for men and 57.9% for women. In multiple regression, depression in men was associated with stealing because of hunger (adjusted Odds Ratio (aOR) 5.78, p = .03), being more controlling in relationships (aOR 0.81, p = .008) and being more ashamed about lack of work (aOR 0.75, p = .01). For women, depressive symptoms were associated with greater stress about lack of work (aOR 0.72, p < .0001) and food insecurity (aOR 5.57, p = .039). The study emphasises that socio-economic factors, shaped by local understandings of gender, play a significant role in depressive symptomology. We suggest reducing economic distress may have an important role in reducing depression in this population.

Comorbid depression and associated factors in PNES versus epilepsy: Systematic review and meta-analysis.

This systematic review aims to contrast levels, manifestations and associations of depression in patients with psychogenic non-epileptic seizures (PNES) and those with epilepsy. ScienceDirect and Web of Science were searched for primary research reports describing quantitative studies involving separate epilepsy and PNES samples (age 16+) and using a validated measure of depression. While 34 studies were identified, most were of low quality and had small sample sizes. Studies consistently found higher levels of self-reported depression in the PNES than epilepsy groups, with a meta-analysis demonstrating a significant difference between the groups. Although patients with PNES were also more likely to have a clinical diagnosis of depression than those with epilepsy, the difference between the groups was less pronounced in studies based on such diagnoses rather than self-report. Patients with PNES were more likely to report physical symptoms of depression than those with epilepsy. Interpersonal factors explained more variation in depression levels in patients with PNES than those with epilepsy, for whom illness related factors were more influential, but in both patient groups, depression had a significant impact on health related quality of life. This systematic review demonstrates a higher prevalence of depression in patients with PNES compared to patients with epilepsy and suggests differences in the expression and possible causes of depression between these groups.

Background Numerous factors influence late-life depressive symptoms in adults, many not thoroughly characterized. We addressed whether genetic and environmental influences on depressive symptoms differed by age, sex, and physical illness. Methods The analysis sample included 24,436 twins aged 40 through 90 drawn from the Interplay of Genes and Environment across Multiple Studies (IGEMS) consortium. Biometric analyses tested age, sex, and physical illness moderation of genetic and environmental variance in depressive symptoms. Results Women reported greater depressive symptoms than men. After age 60, there was an accelerating increase in depressive symptom scores with age, but this did not appreciably affect genetic and environmental variances. Overlap in genetic influences between physical illness and depressive symptoms was greater in men than in women. Additionally, in men extent of overlap was greater with worse physical illness (the genetic correlation ranged from near .00 for the least physical illness to nearly .60 with physical illness two SD above the mean). For men and women, the same environmental factors that influenced depressive symptoms also influenced physical illness. Conclusions Findings suggested that genetic factors play a larger part in the association between depressive symptoms and physical illness for men than for women. For both sexes, across all ages, physical illness may similarly trigger social and health limitations that contribute to depressive symptoms. PMID:28202098

We have previously shown that depression symptoms are associated with multiple risk behaviors and that parental attachments are protective against depression symptoms in post-war adolescents. Accumulating literature indicates that low levels of attachment may sensitize individuals to increased multiple risk behaviors when depression symptoms exist. This investigation examined the interactive effects of attachment and depression symptoms on multiple risk behavior. We conducted hierarchical logistic regression analyses to examine the impact of attachment and depression symptoms on multiple risk behavior in our post-war sample of 551 adolescents in Gulu district. Analyses revealed interactive effects for only maternal attachment-by-depression interaction. Interestingly, high levels of maternal attachment exacerbated the relationship between depression symptoms and multiple risk behaviors while low levels of maternal attachment attenuated this relationship. It is possible that this analysis could be biased by a common underlying factor that influences self-reporting and therefore is correlated with each of self-reported attachment security, depressive symptoms, and multiple risk behaviors. These findings suggest that maternal attachment serves as a protective factor at low levels while serving as an additional risk factor at high levels. Findings support and expand current knowledge about the roles that attachment and depression symptoms play in the development of multiple risk behaviors and suggest a more complex etiology for post-war adolescents.

Few studies have examined the effect of risk factor modifications on depression incidence. This study was to explore psychosocial risk factors for depression and quantify the effect of risk factor modifications on depression incidence in a large-scale, longitudinal population-based study. Data were from the Montreal Longitudinal Catchment Area study (N=2433). Multivariate modified Poisson regression was used to estimate relative risk (RR). Population attributable fractions were also used to estimate the potential impact of risk factor modifications on depression incidence. The cumulative incidence rate of major depressive disorder at the 2-year follow-up was 4.8%, and 6.6% at the 4-year follow-up. Being a younger adult, female, widowed, separated or divorced, Caucasian, poor, occasional drinker, having a family history of mental health problems, having less education and living in areas with higher unemployment rates and higher proportions of visible minorities, more cultural community centres and community organisations, were consistently associated with the increased risk of incident major depressive disorder. Although only 5.1% of the disease incidence was potentially attributable to occasional drinking (vs abstainers) at the 2-year follow-up, the attribution of occasional drinking doubled at the 4-year follow-up. A 10% reduction in the prevalence of occasional drinking in this population could potentially prevent half of incident cases. Modifiable risk factors, both individual and societal, could be the targets for public depression prevention programmes. These programmes should also be gender-specific, as different risk factors have been identified for men and women. Public health preventions at individual levels could focus on the better management of occasional drinking, as it explained around 5%~10% of incident major depressive disorders. Neighbourhood characteristics could also be the target for public prevention programmes. However, this could be very challenging. A cost-effectiveness analysis of a variety of prevention efforts is warranted. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

Static chamber measurements of N2O fluxes were taken during the 1998 and 1999 growth seasons in a Swedish constructed wetland receiving wastewater. The dominating plant species in different parts of the wetland were Lemna minor L., Typha latifolia L., Spirogyra sp. and Glyceria maxima (Hartm.) and Phalaris arundinacea (L.), respectively. There were large temporal and spatial variations in N2O fluxes, which ranged from consumption at -350 to emissions at 1791 μg N2O m-2 h-1. The largest positive flux occurred in October 1999 and the lowest in the middle of July 1999. The average N2O flux for the two years was 130 μg N2O m-2 h-1 (SD = 220). No significant differences in N2O fluxes were found between the years, even though the two growing seasons differed considerably with respect to both air temperature and precipitation. 15% of the fluxes were negative, showing a consumption of N2O. Consumption occurred on a few occasions at most measurement sites and ranged from 1-350 μg N2O m-2 h-1. 13-43% of the variation in N2O fluxes was explained by multiple linear regression analysis including principal components. Emission factors were calculated according to IPCC methods from the N2O fluxes in the constructed wetland. The calculated emission factors were always lower (0.02-0.27%) compared to the default factor provided by the IPCC (0.75%). Thus, direct application of the IPCC default factor may lead to overestimation of N2O fluxes from constructed wastewater-treating wetlands.

To determine whether psychosocial factors predict depression among older African American patients with cancer. A descriptive correlational study. Outpatient oncology clinic of a National Cancer Institute-designated cancer center in the southeastern United States. African American patients with cancer aged 50-88 years. Fisher's exact and Wilcoxon rank-sum tests were used to evaluate differences between patients who were possibly depressed (Geriatric Depression Scale) or not. Multivariate linear regression statistics were used to identify the psychosocial factors that predicted higher depression scores. Education and gender were included as covariates. Religiosity, emotional support, collectivism, perceived stigma, and depression. Participants (N = 77) had a mean age of 61 years (SD = 8.4), and a majority were well-educated, insured, religiously affiliated, and currently in treatment. Participants who were in the lowest income category, not married, or male had higher depression scores. The multivariable model consisting of organized religion, emotional support, collectivism, education, and gender explained 52% (adjusted R2) of the variation in depression scores. Stigma became insignificant in the multivariable model. Psychosocial factors are important predictors of depression. Emotional support and organized religious activities may represent protective factors against depression, whereas collectivism may increase their risk. Nurses need to be particularly aware of the potential psychological strain for patients with collectivist values, experienced stigma, disruptions in church attendance, and lack of emotional support. In addition, the treatment plans for these patients should ensure that family members are knowledgeable about cancer, its treatment, and side effects so they are empowered to meet support needs. Among older African American patients with cancer, emotional support and reassurance from family and friends that they will not abandon them decreases the likelihood of depressive symptoms and minimizes the impact of stigmatizing responses, but the perception that the illness is placing a strain on the family increases the likelihood of such symptoms. Emotional support likely is a stronger predictor of depressive symptoms than religious service attendance.

The purpose of this study was to investigate the health behaviors and risk factors for self-reported depression in Korean working women. This study adopted a secondary analysis from the fifth Korean National Health and Nutrition Examination Survey (KNHANES-V) for the Health Examination Survey and Health Behavior Survey, using stratified, multi-stage, cluster-sampling design to obtain a nationally representative sample. Data were gathered on extensive information including sociodemographic, occupational characteristics, health behaviors and depression. Multiple logistic regression analysis was employed to compute the odds ratio (OR) between health behaviors and depression to identify the health behaviors and the risk factors for depression with adjustment for the complex sample design of the survey. The prevalence rate of depression was 15.5% among working women. Depression was more common in older female workers and in those with part-time job. Current smokers were significantly more likely to be depression-positive. In a multiple logistic regression analysis, significant variables of depression were marital status (OR = 2.02; 95% CI [1.05, 3.89]), smoking status (OR = 1.55; 95% CI [1.01, 2.38]), stress (OR = 0.20; 95% CI [0.15, 0.26]), employment condition (OR = 1.77; 95% CI [1.34, 2.33]) and health status (OR = 2.10; 95% CI [1.53, 2.87]). Based on the study, factors leading to depression were marital status, current smoking, stress, employment condition and self-reported health status. Further studies are expected to unravel the characteristics of stress. Health care providers for women need to evaluate underreported depression and change their associated health behaviors. Also it is necessary to establish preventive strategies for female workers to control the negative effect of depression in the workplace. Copyright © 2015. Published by Elsevier B.V.

Background Diabetes mellitus, frequently associated with comorbid depression, contributes to the double burden of individual patients and community. Depression remains undiagnosed in as many as 50%–75% of diabetes cases. This study aimed to determine the prevalence and associated factors of depression among diabetic patients attending the University of Gondar Hospital Diabetic Clinic, Northwest Ethiopia. Methods An institution-based cross-sectional study was conducted from March to May 2014 among 422 sampled diabetic patients attending the University of Gondar Hospital Diabetic Clinic. The participants were selected using systematic random sampling. Data were collected by face-to-face interview using a standardized and pretested questionnaire linked with patient record review. Depression was assessed using the Patient Health Questionnaire-9. Data were entered to EPI INFO version 7 and analyzed by SPSS version 20 software. Binary logistic regression analysis was performed to identify factors associated with depression. Results A total of 415 diabetic patients participated in the study with a response rate of 98.3%. The prevalence of depression among diabetic patients was found to be 15.4% (95% confidence interval (CI): 11.7–19.2). Only religion (adjusted odds ratio [AOR] =2.65 and 95% CI: 1.1–6.0) and duration of diabetes (AOR =0.27 and 95% CI: 0.07–0.92) were the factors associated with depression among diabetic patients. Conclusion The prevalence of depression was low as compared to other similar studies elsewhere. Disease (diabetes) duration of 10 years and above and being a Muslim religion follower (as compared to Christian) were the factors significantly associated with depression. Early screening of depression and treating depression as a routine component of diabetes care are recommended. Further research with a large sample size, wider geographical coverage, and segregation of type of diabetes mellitus is recommended. PMID:27274296

2015-01-01

Introduction Major depressive disorder (MDD) is the most frequent comorbid psychiatric condition associated with obsessive-compulsive disorder (OCD). This study aimed to evaluate the prevalence of current depression in OCD, differences in socio-demographic and clinical characteristics, and obsessive-compulsive symptoms between OCD patients with and without depression. Additionally, factors associated with comorbid depression were investigated in our study. Methods In total, 140 OCD patients, of which 63 were OCD patients with MDD (OCD+MDD, n=63) and 77 were OCD patients without depression (OCD−MDD, n=77) were included in the study. All patients were diagnosed with OCD using the Structured Clinical Interview for DSM-IV. The Yale–Brown Obsessive-Compulsive Scale, Beck Anxiety Scale, and Beck Depression Scale were administered to all patients. After the socio-demographic and clinical variables and scales were accomplished, the OCD patients divided into two groups as OCD with or without depression and we compared their mean scores of the variables and scales. Univariate analyses were followed by logistic regression. Results There were no significant differences in age, gender, marital status, period without treatment, profession, medical and family history, and social support between the two groups. Anxiety, depression, and obsession and compulsion scores were significantly higher in the OCD+MDD group. The avoidance, insight, instability, and retardation scores of the OCD+MDD group were also significantly higher than those of the OCD−MDD group. Conclusion Our study suggests that many factors are strongly associated with depression in OCD. Positive correlations between poor insight, severity of obsession and compulsion, and stressful life events during the last six months increased the risk of depression in OCD. Our study suggests that high level of avoidance, instability and retardation, history of suicidal attempt, and delayed treatment are other notable factors associated with the development of depression in OCD.

Mental health problems, in general, and major depression in particular, are prevalent among incarcerated men. It is estimated that 23% of state inmates report experiencing symptoms of major depression. Despite the high rates of depressive symptoms, there is little understanding about the psychosocial factors that are associated with depressive and anxiety symptoms of incarcerated men. One factor relevant to the mental health of incarcerated men is their adherence to traditional masculine norms. We investigated the role of masculine norms and informal support on depressive and anxiety symptoms among 123 incarcerated men. The results revealed that adherence to the masculine norm of emotional control were negatively associated with depressive symptoms while heterosexual presentation and informal support were related to both depressive and anxiety symptoms. High levels of reported informal support moderated the effects of heterosexual presentation on depressive and anxiety symptoms. Public health and clinical implications are discussed. PMID:23139638

Is depression an inflammatory condition? A review of available evidence.

Hashmi, Ali Madeeh; Butt, Zeeshan; Umair, Muhammad

2013-07-01

The current review examines the relationship between depression and the inflammatory immune response. Mood disorders are a significant cause of morbidity and the etiology of depression is still not clearly understood. Many studies have shown links between inflammatory cytokines and mood disorders, including elevated level of cytokines like tumour necrosis factor-alpha (TNF alpha), Interleukins (IL-1,IL-6) and others. Raised levels of cytokines have been shown to increase depressive behaviour in animal models, while many anti-depressants reverse this behaviour alongside reducing the Central Nervous System (CNS) inflammatory response and reduction in the amounts of inflammatory cytokines. Cytokines reduce neurogenesis, Brain Derived Neurotrophic Factor (BDNF) and neuronal plasticity in the CNS, while many anti-depressants have been shown to reverse these processes. The considerations of anti-depressants as anti-inflammatory agents, and implication of other anti-inflammatory therapeutics for the treatment of depression are pointed out.

The researchers studied differences in self-reported music experience and depression across ethnic groups, as well as differences in the relationship between music experience and depression across groups. College participants (78 African Americans, 111 Asian Americans, 218 Whites, and 87 in other ethnic groups) completed the Music Experience Questionnaire (MEQ) and the Center for Epidemiological Studies Depression scale. Statistically significant differences across groups were found on depression as well as on the MEQ factor for Subjective/Physical Reactions to music and on MEQ scales for Commitment to Music, Affective Reactions, Positive Psychotropic Effects, and Reactive Musical Behavior. A distinctive pattern of relationship was found between music variables and depression in the Asian American group, relative to the White and Other group. In particular, among Asian Americans there were negative correlations between depression and the MEQ Subjective/ Physical Reactions factor as well as the Affective Reactions scale. Implications were discussed for the literature on ethnicity and depression, music experience, and music therapy.

The study investigated to compare health care utilization and expenditures between diabetic patients with and without depression in Taiwan. Health care utilization and expenditure among diabetic patients with and without depression disorder during 2000 and 2004 were examined using Taiwan's population-based National Health Insurance claims database. Health care utilization included outpatient visits and the use of inpatient services, and health expenditures were outpatient, inpatient, and total medical expenditures. Moreover, general estimation equation models were used for analyzing the factors associated with outpatient visits and expenditures. Multiple logistic regression analysis was applied for identifying the factors associated with hospitalization. The average annual outpatient visits and annual total medical expenditures in the study period were 44.23-52.20; NT$87,496-133,077 and 30.75-32.92; NT$64,411-80,955 for diabetic patients with and without depression. After adjustment for covariates, our results revealed that gender and complication were associated with out-patient visits. Moreover, the time factor was associated with the total medical expenditure, and residential urbanization and complication factors were associated with hospitalization. Health care utilization and expenditures for diabetic patients with depression were significantly higher than those without depression. Sex, complications, time, and urbanization are the factors associated with health care utilization and expenditures.

To investigate the impact of disease-related aspects on long-term variations in fatigue in persons with rheumatoid arthritis. Observational longitudinal study. Sixty-five persons with rheumatoid arthritis, age range 20-65 years, were invited to a clinical examination at 4 time-points during the 4 seasons. Outcome measures were: general fatigue rated on visual analogue scale (0-100) and aspects of fatigue assessed by the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire. Disease-related variables were: disease activity (erythrocyte sedimentation rate), pain threshold (pressure algometer), physical capacity (six-minute walk test), pain (visual analogue scale (0-100)), depressive mood (Hospital Anxiety and Depression scale, depression subscale), personal factors (age, sex, body mass index) and season. Multivariable regression analysis, linear mixed effects models were applied. The strongest explanatory factors for all fatigue outcomes, when recorded at the same time-point as fatigue, were pain threshold and depressive mood. Self-reported pain was an explanatory factor for physical aspects of fatigue and body mass index contributed to explaining the consequences of fatigue on everyday living. For predicting later fatigue pain threshold and depressive mood were the strongest predictors. Pain threshold and depressive mood were the most important factors for fatigue in persons with rheumatoid arthritis.

This study explores the relationship between reported parental emotional neglect when a child, assault type experienced, posttraumatic stress symptoms (PTSS), depression, and alcohol consumption in treatment seekers for comorbid depressive symptoms and alcohol misuse. Participants ( n = 220) with concurrent depression and alcohol misuse were recruited from the DAISI (Depression and Alcohol Integrated and Single-focussed Interventions) project. Assault type and PTSS were retrospectively assessed by the Posttraumatic Stress Diagnostic Scale. The Measure of Parenting Style is a self-report measure that retrospectively assessed emotional neglect experienced as a child. An exploratory factor analysis using the tetrachoric correlation matrix (applying principal factor extraction with a varimax rotation) identified the two assault factors of sexual assault ( SA ) and physical assault ( PA ). A path analysis revealed that Maternal Emotional Neglect increased the impact of PTSS and depression. Paternal Emotional Neglect increased the impact of PA on PTSS and alcohol dependence symptoms. There appears to be differential effects of assault type and Maternal/Paternal emotional neglect on depression and alcohol misuse, suggesting that parenting roles serve distinct protective functions.

Depression and dementia: cause, consequence or coincidence?

The relationship between depression and dementia is complex and still not well understood. A number of different views exist regarding how the two conditions are linked as well as the underlying neurobiological mechanisms at work. This narrative review examined longitudinal and cross sectional studies in the existing literature and determined the evidence supporting depression being a risk factor, a prodrome, a consequence, or an independent comorbidity in dementia. Overall there is convincing evidence to support both the notion that early life depression can act as a risk factor for later life dementia, and that later life depression can be seen as a prodrome to dementia. There is also evidence to support both conditions showing similar neurobiological changes, particularly white matter disease, either indicating shared risk factors or a shared pattern of neuronal damage. These findings highlight the need to examine if effective treatment of depressive episodes has any effect in reducing the prevalence of dementia, as well as clinicians being vigilant for late life depression indicating the incipient development of dementia, and therefore carefully following up these individuals for future cognitive impairment.

This study investigated whether racial disparities in depression were present after Hurricane Katrina. Data were gathered from 932 New Orleans residents who were present when Hurricane Katrina struck, and who returned to New Orleans the following year. Multiple logistic regression models evaluated racial differences in screening positive for depression (a score ≥16 on the Center for Epidemiologic Studies Depression Scale), and explored whether differential vulnerability (prehurricane physical and mental health functioning and education level), differential exposure to hurricane-related stressors, and loss of social support moderated and/or reduced the association of race with depression. A univariate logistic regression analysis showed the odds for screening positive for depression were 86% higher for African Americans than for Caucasians (odds ratio [OR] = 1.86 [1.28-2.71], p = .0012). However, after controlling simultaneously for sociodemographic characteristics, preexisting vulnerabilities, social support, and trauma-specific factors, race was no longer a significant correlate for screening positive for depression (OR = 1.54 [0.95-2.48], p = .0771). The racial disparity in postdisaster depression seems to be confounded by sociodemographic characteristics, preexisting vulnerabilities, social support, and trauma-specific factors. Nonetheless, even after adjusting for these factors, there was a nonsignificant trend effect for race, which could suggest race played an important role in depression outcomes following Hurricane Katrina. Future studies should examine these associations prospectively, using stronger assessments for depression, and incorporate measures for discrimination and segregation, to further understand possible racial disparities in depression after Hurricane Katrina.

Background Disasters are destructive, potentially traumatic events that affect millions of youth each year. Objective The purpose of this paper was to review the literature on depressive symptoms among youth after disasters. Specifically, we examined the prevalence of depression, risk factors associated with depressive symptoms, and theories utilized in this research area. Methods We searched MEDLINE, PsycInfo, and PubMed electronic databases for English language articles published up to May 1, 2013. Reference lists from included studies were reviewed to capture additional studies. Only quantitative, peer reviewed studies, conducted with youth under the age of 18 years, that examined postdisaster depressive symptoms were included. Seventy-two studies met inclusion criteria. Prevalence of depressive symptoms, disaster type, correlates of depressive symptoms, and theories of depressive symptoms were reviewed. Results Only 27 studies (38%) reported on prevalence rates among youth in their sample. Prevalence rates of depression among youth postdisaster ranged from 2% to 69%. Potential risk factors were identified (e.g., female gender, exposure stressors, posttraumatic stress symptoms). Theories were examined in less than one-third of studies (k = 21). Conclusions Given the variability in prevalence rates, difficulty identifying a single profile of youth at risk for developing depressive symptoms, and lack of a unifying theory emerging from the studies, recommendations for future research are discussed. Use of established batteries of assessments could enable comparisons across studies. Merging existing theories from children’s postdisaster and depression literatures could aid in the identification of risk factors and causal pathways. PMID:25067897

Understanding major depressive disorder among middle-aged African American men.

This paper is a report of a study of how a cohort of African American men recognized and expressed symptoms of depression, and how depression affected their lives. Major depressive disorder has had global financial consequences in the form of healthcare visits, lost work hours, and disruption of family lives. Early recognition of depression and engagement of depressed individuals to promote management and treatment of this disorder is crucial in controlling its impact. African American men are often not included in research exploring factors that limit their engagement in mental health care. A descriptive qualitative study using semi-structured interviews was conducted in 2008 with ten African American men between the ages of 40 and 59 years. All participants self-reported a history of depression. Three central themes were identified: life events, the funk, and the breakdown. Life events were identified as stressors which led the men to experience what they described as the funk, which was later identified as depression. Due to lack of resolution of the funk, a breakdown was experienced. Over time study participants became informed about their condition, and their responses to managing depression varied depending on individual and contextual factors. It is important to approach depression diagnoses from a broad perspective rather than as a limited list of symptoms. Healthcare providers would benefit from taking into account cultural factors, gender and age, examining them carefully in relation to the development of depressive symptoms.

Despite widespread recognition of the occurrence of antisocial behavior and depression in adolescents, the specifics of the relationship between them have not been clarified. The purpose of this study was to investigate the role of expressed emotion as a proximal factor for depression and antisocial behavior among adolescents, by looking at direct and indirect relationships. Secondary data analysis using path analysis was carried out on 2004 data from the Child and Adolescent Behaviors in Long-term Evaluation project. The study sample consisted of 1599 seventh-grade students in Northern Taiwan. Variables included family factors, personal factors (sex and academic performance), expressed emotion [emotional involvement (EI) and perceived criticism (PC)], depression, and antisocial behavior. We found that one dimension of expressed emotion, PC, directly influenced student depression and related indirectly to antisocial behavior. Depression was an important mediator between PC and antisocial behavior. Another dimension, EI, did not influence either depression or antisocial behavior. Sex was related directly to expressed emotion, depression, and antisocial behavior, and also indirectly to antisocial behavior through PC and depression. Academic performance was related directly to expressed emotion and indirectly to antisocial behavior through PC and depression. Greater PC from parents directly contributed to higher levels of student depression and was related indirectly to more student antisocial behavior. It is suggested that parents should decrease overly critical parenting styles to promote adolescent mental health and avoid the development of antisocial behavior.

Background: It is unclear whether there is an association between chronotype and nonremission of depression, and whether the association is related to the confounding effect of insomnia. Method: A cohort of patients with major depressive disorder were assessed for chronotype (by Morningness-Eveningness Questinnaire [MEQ]), depressive symptoms, insomnia severity and clinical outcomes in a naturalistic follow-up study. Results: Of the 253 recruited subjects (age 50.8 ± 10.2 y; female: 82.6%; response rate 90.0%), 19.4%, 56.1% and 24.5% patients were classified as eveningness, intermediate, and morningness, respectively. Evening-type subjects had higher insomnia severity, more severe depressive symptoms, and higher suicidality. Eveningness was associated with nonremission of depression with an odds ratio (OR) of 3.36 (95% confidence interval [CI] 1.35–8.34, P < 0.01), independent of insomnia severity. In addition, insomnia was an independent significant factor in contributing to nonremission of depression (OR = 1.12; 95% CI 1.05–1.19, P < 0.001). Conclusion: The independent association of eveningness with nonremission of depression suggested a significant underpinning of circadian involvement in major depressive disorder. Our findings support the need for a comprehensive assessment of sleep and circadian disturbances as well as integration of sleep and chronotherapeutic intervention in the management of depression.

Depression is a serious, costly, and debilitating disorder that is understudied in rural women. Studies show that depression is associated with low social integration and support, but few studies investigate the relationship between depression and social network characteristics. This study examined the associations among women from three Ohio Appalachian counties enrolled in a health study, which aimed to collect information for a future social network smoking cessation intervention. An address-based sampling method was used to randomly select and recruit 404 women. A cross-sectional survey and interview were used to collect information about demographic, psychosocial, behavioral factors, and ego-centric social network characteristics, which are variables derived from an individual (ego) and her first degree contacts (alters). The CES-D scale assessed depressive symptoms. A multivariable logistic regression analysis described the association between these factors and participants with depression (defined as CES-D≥16). Higher network density, or greater number of relationships among alters divided by the total amount of alters, reduced the risk for depression (OR = 0.84, 95% confidence interval [CI] 0.73–0.95). Additionally, women with a high percentage of smoking alters were at greater risk for depression (OR = 1.19, 95% CI 1.02–1.39). Other factors associated with risk for depression included perceived stress score (OR = 1.34, 95% CI 1.24–1.45), loneliness score (OR = 1.37, 95% CI 1.05–1.80), and days with poor physical health (OR = 1.06, 95% CI 1.02–1.11). Findings suggest that psychosocial factors and social networks should be considered when addressing depression in clinical practice. PMID:29081878

Women are serving in the armed forces and deployed to areas of conflict in increasing numbers. Problems such as depressive symptoms and risks related to combat exposure can have negative effects on adjustment following service; understanding the relationship between these problems may contribute to strategies providers can use to facilitate healthy adjustment after deployment. The purpose of this study is to examine social factors as they relate to mental health adjustment, namely depressive symptoms among female veterans who served in Iraq and Afghanistan as part of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OND). We hypothesized that combat exposure would predict higher levels of depressive symptoms and that social support would moderate the relationship between combat exposure and depression. In a cross-sectional design, 128 female Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans completed an online survey about combat experience, social support, depression, demographic characteristics, and behavioral health symptom history. We conducted multiple regression analyses to examine linear and moderating relationships. There was no significant relationship between combat exposure and depression; social support did not significantly moderate the relationship between combat exposure and depression. However, higher levels of social support and financial comfort were significantly related to lower levels of depression. This study highlights the role of social factors, specifically social support and perceived financial status, as potential barriers to healthy emotional readjustment following deployment. These findings suggest that it may be beneficial for mental health providers to screen female veterans and refer them to appropriate services to reduce financial stressors and strengthen their use of social support. More research should continue to examine more fully the impact of combat exposure on female service members' mental health and work to isolate the factors most strongly related to depression.

Social support is related to patient self-care and health status. Patients' psychosocial issues play an important role in diabetes care. This study investigates correlations among social support, depression, and anxiety in patients with diabetes. A cross-sectional study design and purposive sampling were used. One hundred eleven patients with type-2 diabetes were recruited from three regional teaching hospitals in northern, central, and southern Taiwan, respectively. Questionnaires used included the social support and psychological referral inventory, Beck depression inventory, and Beck anxiety inventory. Approximately 12.6% of the study population had depression, and 27.0% had anxiety. Depression and anxiety were positively correlated (r = .65, p < .01), whereas depression was negatively correlated with the sum of disease control types (r = -0.26, p < .01) and social support (r = -0.27, p <.01). The sum of disease control types and social support were the most important explanatory factors for depression in patients, explaining 45.5% of variance. Anxiety was correlated positively with age (r = .26, p < .01), total number of complications (r = .31, p < .01), and depression (r = .65, p < .01). Anxiety correlated negatively with weight (r = -0.20, p < .05) and sum of disease control types (r = -0.25, p < .05). The above variables were important explanatory factors for anxiety, accounting for 15.2% of variance. Psychological factors, such as depression and anxiety, are common symptoms in patients with diabetes. If social support can be strengthened in these patients, then psychological factors can be improved. Professional care providers should focus on reducing the patient depression and anxiety levels, strengthening social support, and providing referrals to psychology-related professionals.

To investigate the prevalence of depressive symptom and its influencing factors among primary and middle school students in urban-rural-integrated area of Chongqing. A total of 3 013 primary and middle school students from an urban-rural-integrated area of Chongqing were selected by using multistage stratified cluster sampling method in this study. The general information, physical activities and physical examination conditions were investigated. Meanwhile, the depress symptoms were assessed by using children's depression inventory (CDI) and the incidence of adolescence related events were evaluated by using pubertal development scale (PDS). Chi-square test was used to analyze the detection rate of depression symptoms among different population and Logistic regression was used to analyse the influencing factors of depressive symptoms among primary and middle school students. The detection rate of depressive symptoms was 20.1% (607/3013) totally, and it was gradually higher among the students with bad to good economic status (28.3%/18.4%/18.3%, chi2 = 28.415, P < 0.05). The students' detection rate of depression symptoms in different development level compared to companion by self image were 43.1%, 26.5%, 22.0% and 15.8% (chi2 = 79.621, P < 0.01). Among the senior school students, worse economic status, higher development level in self-evaluation, and no physical activities in a recent month (including physical training, aerobic exercise) were considered as the influencing factors of depressive symptoms. Focusing on the physical and mental health of growing children, establishing a good school environment and family environment, and strengthening physical activities will contribute to reducing the incidence of depressive symptoms.

Purpose To determine whether psychosocial factors predict depression among older African American cancer patients. Design/Methods A descriptive correlational study. Setting Outpatient oncology clinic of NCI designated Cancer Center in Southeastern U.S. Sample African American cancer patients aged 50 and over. Methods Fisher’s Exact and Wilcoxon Rank Sum tests were used to evaluate differences between patients who were possibly depressed (Geriatric Depression Scale) or not. Multivariate linear regression statistics were used to identify the psychosocial factors that predicted higher depression scores. Education and gender were included as covariates. Main Variables Religiosity, emotional support, collectivism, perceived stigma and depression. Findings African American cancer patients (n=77) were on average a median age of 58 years (IQR = 55–65), a majority were well-educated, insured, religiously affiliated, and currently in treatment. Participants in the lowest income category, not married, and male gender had higher depression scores. The multivariable model consisting of organized religion, emotional support, collectivism, education, and gender explained 52% (adjusted R2) of the variation in depression scores. Stigma became insignificant in the multivariable model. Conclusions Psychosocial factors are important predictors of depression. For these participants, emotional support and organized religious activities may represent protective factors against depression, while collectivism may increase their risk. Implications Nurses need to be especially aware of the potential psychological strain for patients with collectivist values, experienced stigma, disruptions in church attendance and lack of emotional support. Further, these treatment plans for these patients should ensure that family members are knowledgeable about cancer, its treatment and side effects so they are empowered to meet the needs for support of the African American cancer patient.
