Schizophr Res 2024; 266:32-40. [PMID: 38367610 DOI: 10.1016/j.schres.2024.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 01/24/2024] [Accepted: 02/10/2024] [Indexed: 02/19/2024]
Abstract
BACKGROUND The concept of personal recovery after psychotic illness focuses more on patients' social and existential needs compared to traditional outcome measures including clinical and functional recovery. This research aims to contribute to a broad framework on (personal) recovery and associated factors. METHODS Data from 203 persons with symptomatic remission of their first-episode psychosis from the ongoing HAMLETT study were analyzed. To determine the relative importance of several biological, clinical, psychological, and social factors in explaining personal recovery as measured by the Recovery Assessment Scale (RAS), partial Spearman correlations (controlling for clinical recovery (PANSS) and functional recovery (WHODAS 2.0)) and a bootstrapped multiple regression were performed. Indirect effects on personal recovery within these factors, clinical recovery, and functional recovery were explored using a regularized partial correlation network. RESULTS Of the factors that explained personal recovery beyond the effects of clinical and functional recovery, social support was the strongest predictor, followed by self-esteem, internalized stigma, and insecure attachment, collectively explaining 48.2 % of the variance. Anhedonia/apathy showed a trend towards a negative correlation. Age at onset, sex, early trauma/neglect, cognition, and being married/cohabiting did not significantly correlate with personal recovery. The network (n = 143) was consistent with these findings and indicated possible mediation pathways for early trauma/neglect, insecure attachment, cognition, and being married/cohabiting. CONCLUSIONS Personal recovery is an important addition to traditional measures of outcome after psychosis. Various quality of life indicators, such as self-esteem and social support, explain variance in personal recovery over clinical and functional recovery.

Fostering resilience and well-being in emerging adults with adverse childhood experiences: study protocol for a randomized controlled trial to evaluate the FACE self-help app. BMC Psychol 2024; 12:84. [PMID: 38374126 PMCID: PMC10877810 DOI: 10.1186/s40359-024-01560-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 01/29/2024] [Indexed: 02/21/2024] Open
Abstract
BACKGROUND Adverse childhood experiences (ACE) are linked to an increased risk of psychological disorders and lower psychosocial functioning throughout life. This study aims to evaluate the FACE self-help app, designed to promote resilience and well-being in emerging adults with a history of ACE. The app is based on cognitive-behavioural principles and consists of two thematic components: (1) self- and emotion regulation (SER) and (2) social skills and biases in social information processing (SSIP). METHODS The efficacy of the app will be tested through a single-centre, two-arm randomized controlled trial, comparing an active intervention group against a waiting list control group. The active group is divided into two subgroups, in which the two components are delivered in a different order to investigate differential effects in a crossover design. Up to 250 emerging adults aged 18 to 25 years with a history of ACE from a general population cohort study will be recruited. The primary objective is to test the efficacy of the app in improving resilience (primary outcome) and well-being (co-primary outcome) compared to a waiting list control group and to examine the stability of these effects. The secondary objectives include testing the efficacy of the app in improving the secondary outcomes, i.e., self-efficacy in managing emotions, problem solving, fear of evaluation, social avoidance, and self-esteem; examining the differential effects of the two components; and assessing the effect of the app on real-life data on resilience, affective states, distress in social interactions and coping strategies. Furthermore, the study will investigate potential moderators (e.g. ACE severity) and mediators of intervention outcomes (e.g. self-efficacy in managing emotions). DISCUSSION The results will provide insights into the efficacy of the self-help intervention as well as mediators and moderators of outcomes. Furthermore, results will extend the existing knowledge by testing the differential effects of the SER and SSIP component on the outcomes. Findings can inform improvements to the FACE app and the development of other interventions for this target group and assess its potential as a scalable, low-threshold intervention to support emerging adults with a history of ACE in their transition to adulthood. TRIAL REGISTRATION NUMBER NCT05824182.

Evidence for a shared genetic contribution to loneliness and borderline personality disorder. Transl Psychiatry 2023; 13:398.

Abstract
Loneliness, influenced by genetic and environmental factors such as childhood maltreatment, is one aspect of interpersonal dysfunction in Borderline Personality Disorder (BPD). Numerous studies link loneliness and BPD and twin studies indicate a genetic contribution to this association. The aim of our study was to investigate whether genetic predisposition for loneliness and BPD risk overlap and whether genetic risk for loneliness contributes to higher loneliness reported by BPD patients, using genome-wide genotype data. We assessed the genetic correlation of genome-wide association studies (GWAS) of loneliness and BPD using linkage disequilibrium score regression and tested whether a polygenic score for loneliness (loneliness-PGS) was associated with case-control status in two independent genotyped samples of BPD patients and healthy controls (HC; Witt2017-sample: 998 BPD, 1545 HC; KFO-sample: 187 BPD, 261 HC). In the KFO-sample, we examined associations of loneliness-PGS with reported loneliness, and whether the loneliness-PGS influenced the association between childhood maltreatment and loneliness. We found a genetic correlation between the GWAS of loneliness and BPD in the Witt2017-sample (rg = 0.23, p = 0.015), a positive association of loneliness-PGS with BPD case-control status (Witt2017-sample: NkR² = 2.3%, p = 2.7*10-12; KFO-sample: NkR² = 6.6%, p = 4.4*10-6), and a positive association between loneliness-PGS and loneliness across patient and control groups in the KFO-sample (β = 0.186, p = 0.002). The loneliness-PGS did not moderate the association between childhood maltreatment and loneliness in BPD. Our study is the first to use genome-wide genotype data to show that the genetic factors underlying variation in loneliness in the general population and the risk for BPD overlap. The loneliness-PGS was associated with reported loneliness. Further research is needed to investigate which genetic mechanisms and pathways are involved in this association and whether a genetic predisposition for loneliness contributes to BPD risk.

Abstract
Although the role of life stressors in breast cancer remains unclear, social isolation is consistently associated with increased breast cancer risk and mortality. Social isolation can be defined as loneliness or an absence of perceived social connections. In female mice and rats, social isolation is mimicked by housing animals 1 per cage. Social isolation causes many biological changes, of which an increase in inflammatory markers and disruptions in mitochondrial and cellular metabolism are commonly reported. It is not clear how the 2 traditional stress-induced pathways, namely, the hypothalamic-pituitary-adrenocortical axis (HPA), resulting in a release of glucocorticoids from the adrenal cortex, and autonomic nervous system (ANS), resulting in a release of catecholamines from the adrenal medulla and postganglionic neurons, could explain the increased breast cancer risk in socially isolated individuals. For instance, glucocorticoid receptor activation in estrogen receptor positive breast cancer cells inhibits their proliferation, and activation of β-adrenergic receptor in immature immune cells promotes their differentiation toward antitumorigenic T cells. However, activation of HPA and ANS pathways may cause a disruption in the brain-gut-microbiome axis, resulting in gut dysbiosis. Gut dysbiosis, in turn, leads to an alteration in the production of bacterial metabolites, such as short chain fatty acids, causing a systemic low-grade inflammation and inducing dysfunction in mitochondrial and cellular metabolism. A possible causal link between social isolation-induced increased breast cancer risk and mortality and gut dysbiosis should be investigated, as it offers new tools to prevent breast cancer.

Abstract
Stress is a key driver of cardiovascular disease (CVD), yet the contribution of psychosocial stressors to the development of CVD has not been systematically examined in United States (U.S.) populations. The objective of this study was to assess prospective associations of adverse childhood experiences (ACEs), social isolation, and job strain with CVD mortality. Data were from the large, nationally representative, population-based Health and Retirement Study (HRS). ACEs, social isolation and job strain were assessed using validated survey instruments at baseline between 2006-2008, and death information was followed up through 2018. Cox proportional hazards regression models were used to examine prospective associations of ACEs, social isolation, and job strain with CVD mortality among 4046 older employees free from CVD at baseline. During 42,149 person-years of follow-up time, 59 death cases of CVD were reported. After adjustment for covariates, ACEs and job strain were significantly associated with increased risk of CVD mortality (aHR and 95% CI = 3.67 [1.59, 8.48] and 2.24 [1.21, 4.11], respectively), whereas social isolation demonstrated an inflated but nonsignificant association (aHR and 95% CI = 1.62 [0.72, 3.66]). These findings highlight the role of psychosocial exposures as novel and clinically relevant risk factors for CVD.

Abstract
Background Childhood maltreatment has been identified as a risk factor for depressive symptoms. Social anxiety is closely associated with depression. Physical activity has been regarded as an underlying protective factor. Little is known about the complex relations among these factors in Chinese middle school students. This study aimed to explore whether social anxiety mediated the association between childhood maltreatment and depressive symptoms and investigate whether physical activity moderated the indirect or direct effect of the mediation model. Methods A total of 1,570 middle school students were recruited and measured for childhood maltreatment (measured by Childhood Trauma Questionnaire-Short Form Chinese version), social anxiety (as the mediator, measured by the Chinese simplified version of Social Anxiety Scale for Adolescents), depressive symptoms (measured by the Chinese version of Depression Anxiety Stress Scales-21), physical activity (as the moderator), and covariates such as age, sex, and nationality. The proposed relationships were tested using mediation and moderated mediation models. Results Emotional abuse was directly associated with depression, and the association between emotional abuse and depression was partially mediated by social anxiety. The associations between emotional abuse with depression and with social anxiety were moderated by physical activity. Conclusion This study revealed the mediating role of social anxiety and the moderating role of physical activity between emotional abuse and depression, which emphasizes the potential benefits of sufficient physical activity to reduce social anxiety and depressive symptoms, and more intervention studies should be conducted to explore the direct influence of sufficient physical activity in the future.

Abstract
BACKGROUND Adverse childhood experiences (ACEs) negatively impact people's physical and mental health and social functioning. Research literature focuses on the impact of ACEs on physical and mental health, yet to our knowledge, no study has examined the literature on ACEs, mental health, and social functioning outcomes. OBJECTIVE To map how ACEs, mental health, and social functioning outcomes have been defined, assessed, and studied in the empirical literature and identify gaps in the current research which need further investigation. METHODS A scoping review methodology following a five-step framework was implemented. Four databases were searched CINAHL, Ovid (Medline, Embase) and PsycInfo. The analysis involved both numerical and a narrative synthesis in line with the framework. RESULTS Fifty-eight studies were included in the analysis, and three key issues were identified a) the limitations of research samples to date, b) the choice of outcome measures for ACEs, social and mental health outcomes, and c) the limitations of current study designs. CONCLUSION The review demonstrates variability in the documentation of participant characteristics and inconsistencies in the definitions and applications of ACEs, social and mental health and related measurements. There is also a lack of longitudinal and experimental study designs, studies on severe mental illness, and studies including minority groups, adolescents, and older adults with mental health problems. Existing research is highly variable methodologically and limits our broader understanding of the relationships between ACEs, mental health, and social functioning outcomes. Future research should implement robust methodologies to provide evidence that could be used for developing evidence-based interventions.

Abstract
Collective traumas have a notable impact on adolescent well-being. While some youth face increased risk for mental health problems (e.g., those with maltreatment histories), many demonstrate resilience following traumatic events. One contributing factor to well-being following trauma is the degree to which one isolates from others. Accordingly, we examined the association between maltreatment and internalizing problems during the COVID-19 pandemic as moderated by social isolation. Among adolescents reporting pre-pandemic emotional abuse, those experiencing less isolation reported the lowest levels of anxiety symptoms. Among adolescents reporting pre-pandemic physical abuse, those experiencing less isolation reported the greatest levels of anxiety and depressive symptoms. The findings highlight a public health-oriented approach to youth well-being during collective trauma that extends beyond mitigating disease transmission.

Abstract
BACKGROUND Bipolar disorder is a chronic and severe mental health disorder. Early stratification of individuals into subgroups based on age at onset (AAO) has the potential to inform diagnosis and early intervention. Yet, the psychosocial predictors associated with AAO are unknown. AIMS We aim to identify psychosocial factors associated with bipolar disorder AAO. METHOD Using data from the Bipolar Disorder Research Network UK, we employed least absolute shrinkage and selection operator regression to identify psychosocial factors associated with bipolar disorder AAO. Twenty-eight factors were entered into our model, with AAO as our outcome measure. RESULTS We included 1022 participants with bipolar disorder (μ = 23.0, s.d. ± 9.86) in our model. Six variables predicted an earlier AAO: childhood abuse (β = -0.2855), regular cannabis use in the year before onset (β = -0.2765), death of a close family friend or relative in the 6 months before onset (β = -0.2435), family history of suicide (β = -0.1385), schizotypal personality traits (β = -0.1055) and irritable temperament (β = -0.0685). Five predicted a later AAO: the average number of alcohol units consumed per week in the year before onset (β = 0.1385); birth of a child in the 6 months before onset (β = 0.2755); death of parent, partner, child or sibling in the 6 months before onset (β = 0.3125); seeking work without success for 1 month or more in the 6 months before onset (β = 0.3505) and a major financial crisis in the 6 months before onset (β = 0.4575). CONCLUSIONS The identified predictor variables have the potential to help stratify high-risk individuals into likely AAO groups, to inform treatment provision and early intervention.

Abstract
Child maltreatment gives rise to atypical patterns of social functioning with peers which might be particularly pronounced in early adolescence when peer influence typically peaks. Yet, few neuroimaging studies in adolescents use peer interaction paradigms to parse neural correlates of distinct maltreatment exposures. This fMRI study examines effects of abuse, neglect, and emotional maltreatment (EM) among 98 youth (n = 58 maltreated; n = 40 matched controls) using an event-related Cyberball paradigm affording assessment of both social exclusion and inclusion across early and mid-adolescence (≤13.5 years, n = 50; >13.5 years, n = 48). Younger adolescents showed increased activation to social exclusion versus inclusion in regions implicated in mentalizing (e.g., superior temporal gyrus). Individual exposure-specific analyses suggested that neglect and EM coincided with less reduction of activation to social exclusion relative to inclusion in the dorsal anterior cingulate cortex/pre-supplementary motor area (dACC/pre-SMA) among younger versus older adolescents. Integrative follow-up analyses showed that EM accounted for this dACC/pre-SMA activation pattern over and above other exposures. Moreover, age-independent results within respective exposure groups revealed that greater magnitude of neglect predicted blunted exclusion-related activity in the parahippocampal gyrus, while EM predicted increased activation to social exclusion in the precuneus/posterior cingulate cortex.

Investigating emotion regulation and social information processing as mechanisms linking adverse childhood experiences with psychosocial functioning in young swiss adults: the FACE epidemiological accelerated cohort study. BMC Psychol 2022; 10:99. [PMID: 35410310 PMCID: PMC8996489 DOI: 10.1186/s40359-022-00798-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Accepted: 03/29/2022] [Indexed: 11/10/2022] Open
Abstract
Background Adverse childhood experiences increase the risk for psychological disorders and lower psychosocial functioning across the lifespan. However, less is known about the processes through which ACE are linked to multiple negative outcomes. The aim of the FACE epidemiological study is to investigate emotion regulation (emotional reactivity, perseverative thinking and self-efficacy for managing emotions) and social information processing (rejection sensitivity, interpretation biases and social understanding) as potential mechanisms linking adverse childhood experiences and psychosocial functioning in a large population sample of young adults. It is embedded in a larger project that also includes an ecological momentary assessment of emotion regulation and social information processing and informs the development and evaluation of an online self-help intervention for young adults with a history of ACE. Methods The study plans to recruit 5000 young adults aged 18 to 21 from the German-speaking Swiss population. Addresses are provided by Swiss Federal Statistical Office and participants are invited by mail to complete a self-report online survey. If the targeted sample size will not be reached, a second additional sample will be recruited via educational facilities such as universities or teacher training colleges or military training schools. Three follow-ups are planned after 1 year, 2 years and 3 years, resulting in ages 18–24 being covered. The main exposure variable is self-reported adverse childhood experiences before the age of 18, measured at the baseline. Primary outcomes are psychosocial functioning across the study period. Secondary outcomes are social information processing, emotion regulation and health care service use. Statistical analyses include a range of latent variable models to identify patterns of adverse childhood experiences and patterns and trajectories of psychosocial adaptation. Discussion The results will contribute to the understanding of the underlying mechanisms that link ACE with psychosocial functioning which is crucial for an improved insight into risk and resilience processes and for tailoring interventions. Furthermore, the identification of factors that facilitate or hinder service use among young adults with ACE informs healthcare policies and the provision of appropriate healthcare services. Trial registration number: NCT05122988. The study was reviewed and authorized by the ethical committee of Northwestern and Central Switzerland (BASEC number 2021-01204).

Abstract
OBJECTIVE This study aimed to identify vulnerability and protective factors for suicidal histories among adults experiencing psychological trauma. METHOD Adults seeking treatment for psychological trauma (N = 113) completed self-report questionnaires measuring childhood trauma history, self-concept, relational functioning, emotion regulation, living arrangements, employment status, marital status, and suicidal history. Independent samples t-tests were used to determine variables on which those with and without suicidal histories differed significantly. These variables were then entered into a binary logistic regression model to identify factors which independently distinguished between those with and without a suicidal history. RESULTS Univariate differences were found for childhood emotional abuse (CEA), childhood emotional neglect (CEN), emotion deactivation, and employment status, with those in the suicidal history group scoring higher on all of these. CEA (OR = 1.13, 95% CI = 1.01-1.27) and employment status (OR = 4.12, 95% CI = 1.23-13.73) remained significant predictors of suicidal status in the multivariable logistic regression. CONCLUSIONS CEA was an independent vulnerability factor for suicidal risk, highlighting the need for clinicians to assess exposure to such trauma in those presenting with proximal traumatic experiences. Being in employment was an independent protective factor against suicidal risk, highlighting the importance of social buffers or networks when faced with traumatic situations.

Abstract
Social isolation - the lack of social contacts in number and frequency - has been shown to have a negative impact on health and well-being. Using group-based trajectory analysis of longitudinal data from a New Zealand birth cohort, we created a typology of social isolation based on onset during the life course and persistence into adulthood. We then characterized each type according to risk factors related to family environment and child behavior that have been shown previously to be associated with social isolation. Based on fit statistics and distinctness of trajectories we considered the four-class model to be the most appropriate: (1) 'never isolated' (71.6 % of the cohort), (2) 'adult only' (10.1 %), (3) 'child only' (14.3 %), and (4) 'persistent isolation' (4.0 %). Family-environmental factors - i.e. having a teen-aged mother, having a single parent, frequent changes in residence, or maltreatment - tended to be associated with both child and adult onset and persistence of social isolation, whereas child-behavioral factors - i.e. self-control or internalizing symptoms - applied more to the child onset of social isolation. Sensitivity analyses using empirically defined groups - based on 15 % 'cut-offs' for isolation in childhood and adulthood - produced similar life-course groupings and similar associations. Our findings provide insights into the development of social isolation and demonstrate the changeability of social isolation across almost four decades of the life span. They also suggest family-based and child-based interventions could address child onset and the persistence of social isolation into adulthood.

J Eat Disord 2021; 9:119. [PMID: 34565487 PMCID: PMC8474934 DOI: 10.1186/s40337-021-00480-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 09/19/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Unhealthy changes in eating behavior among people experiencing trauma have been observed. There is, however, a lack of in-depth knowledge regarding the impact of the after effects of traumatic life experiences on eating behavior. Because eating behavior represents important components for promotion and maintenance of good health throughout life, this study aimed to explore inpatients' lived experiences of the impact of traumatic stress on eating behavior. METHOD Thirteen female and two male inpatients (age range 28-62 years), recruited from a psychiatric clinic in Norway, participated in this qualitative explorative focus group study. The data analysis was performed using systematic text condensation. RESULTS The results in the present study describe the participants' experiences about the impact of traumatic stress on their eating behavior. Their discussions and descriptions disclosed problems that could be summarized into four main themes: "experiencing eating behaviors as coping strategies"; "experiencing being addicted to food and sweets"; "experiencing eating behaviors controlled by stress and emotions"; and "experiencing lack of appetite and reduced capacity to plan and prepare meals". CONCLUSION Traumatic stress can impact eating behavior in several complex ways that over time may cause adverse health consequences. The results add to an important understanding of changes in eating behavior that might appear in people struggling to cope with the after effects of traumatic life experiences to the existing literature. To better understand the complexity of how traumatic experiences may impact eating behavior, this knowledge is important and useful for health professionals offering support to those who experience struggling with eating behavior after traumatic experiences.

Abstract
Although a large body of literature has examined the effect of social capital on health and theoretical models suggest a reciprocal relationship between the two variables, there are relatively few studies that have investigated the effect of mental health on social capital. This paper evaluates the impact of mental health on the stock of social capital using data from the cross-sectional 2012 (N = 21,844) and 2002 (N = 31,089) Canadian Community Health Survey - Mental Health editions. Mental health was measured retrospectively as self-rated mental health, past year mental health conditions, and past 30-day psychological distress. Given the reciprocal relationship, we used an instrumental variable approach with family history of mental health problems as the instrument and examined forms of social capital - sense of belonging and workplace social support - that are largely measures of social capital provided by non-family members in the community and workplace. The analysis suggests there are large and significant associations between measures of mental health and both outcomes, which persist in the instrumental variable analyses. These findings highlight the urgent need for policy makers to implement greater prevention and treatment of poor mental health, and provide greater support for individuals with poor mental health so they can build and maintain their social capital.

Abstract
Loneliness is a mental health issue emerging over the life course. This study examines the latent structure of adult loneliness in a non-Western society and its association with adverse adolescence experiences (AAEs) as well as feeling lonely during middle school, high school, and college. Method: A cohort sample living in Northern Taiwan (N = 2,289) was analyzed from adolescence to adulthood. The de Jong Gierveld Loneliness Scale operationalized loneliness by a three-cluster model to present the latent structure of loneliness: emotional, serious emotional, and severe emotional/social loners. AAEs (e.g., abuse, neglect, and dysfunctional family) were measured by seven items. Multivariate multinomial logistic regression models were used to explore the longitudinal effects of AAEs and feeling lonely reported during middle school, high school, and college on adult loneliness. Results: AAEs and feeling lonely during adolescence were significantly associated with serious emotional loneliness and severe emotional/social loneliness during adulthood, even after adjusting for the individual’s characteristics. Attendance at a 4-year college was associated with decreased odds of serious emotional loneliness and severe emotional/social loneliness. Conclusions: Adults with AAEs and feelings of loneliness over life stages are more likely to report loneliness in the emotional and social domains.

Abstract
PURPOSE The Neonatal Intensive Care Unit Hospital Exposures and Long-Term Health (NICU-HEALTH) longitudinal preterm birth cohort studies the impact of the NICU exposome on early-life development. NICU-HEALTH collects multiple biospecimens, complex observational and survey data and comprehensive multisystem outcome assessments to allow measurement of the impact of modifiable environmental exposures during the preterm period on neurodevelopmental, pulmonary and growth outcomes. PARTICIPANTS Moderately preterm infants without genetic or congenital anomalies and their mothers are recruited from an urban academic medical centre level IV NICU in New York City, New York, USA. Recruitment began in 2011 and continues through multiple enrolment phases to the present with goal enrolment of 400 infants. Follow-up includes daily data collection throughout the NICU stay and six follow-up visits in the first 2 years. Study retention is 77% to date, with the oldest patients turning age 8 in 2019. FINDINGS TO DATE NICU-HEALTH has already contributed significantly to our understanding of phthalate exposure in the NICU. Phase I produced the first evidence of the clinical impact of phthalate exposure in the NICU population. Further study identified specific sources of exposure to clinically relevant phthalate mixtures in the NICU. FUTURE PLANS Follow-up from age 3 to 12 is co-ordinated through integration with the Environmental Influences on Child Health Outcomes (ECHO) programme. The NICU-HEALTH cohort will generate a wealth of biomarker, clinical and outcome data from which future studies of the impact of early-life chemical and non-chemical environmental exposures can benefit. Findings from study of this cohort and other collaborating environmental health cohorts will likely translate into improvements in the hospital environment for infant development. TRIAL REGISTRATION NUMBERS This observational cohort is registered with ClinicalTrials.gov (NCT01420029 and NCT01963065).

Abstract
Previous research has found a relationship between child abuse and non-suicidal self-injury (NSSI). However, few studies have examined the role of social support underlying this association. Moreover, the influence of the only child status on the mediating effect of social support has not been studied yet. The aim of this study was to investigate the mediating role of social support on the association between specific forms of child abuse and NSSI as well as the role of the only child status on the mediated pathways, among undergraduates. A total of 4799 participants were selected from two medical colleges in the Anhui province using stratified cluster sampling. Pearson's correlation analysis was used in analyzing the relationship. Bootstrapping procedures were applied to examine the mediating effects. After adjusting for confounders, the results showed that the mediating effect of social support on the association between childhood abuse and NSSI was not significant in the total sample. However, among only children, the mediating effects of social support between overall childhood abuse, physical abuse, emotional abuse, and NSSI were 9.65%, 14.82%, and 8.12%, respectively. Moreover, the mediating effect of social support from family and relatives was relatively higher than that from other sources. Social support had a mediating effect on the relationship between childhood abuse and NSSI among only-children. The enhancing of social support may contribute to the prevention and control of NSSI for those who were only-children in undergraduates, especially those who have experienced childhood abuse.

Abstract
BACKGROUND Exposure to childhood abuse has been identified as a salient risk factor for the development of depression. However, the mediating factors between childhood abuse and depressive symptoms have not been sufficiently elucidated. This study aims to investigate the mediating effects of neuroticism, social support, and coping style between childhood abuse and depressive symptoms in population covering general adults, depressed patients, bipolar disorder patients, and high risk population for depression. METHODS This is a cross-sectional study. Five validated questionnaires were used to measure the psychological outcomes (Childhood Trauma Questionnaire CTQ-SF, Eysenck Personality Questionnaire EPQR-S, Social Support Rating Scale SSRS, Simplified Coping Style Questionnaire SCSQ, and Patient Health Questionnaire-9 PHQ-9) of 312 participants. Multiple regressions and structural equation modeling (SEM) were used to conduct data analysis. RESULTS Multiple regression analysis and SEM showed a significant association between childhood emotional abuse and depression symptoms. Neuroticism, use of social support, and active coping style were important mediating variables of this association. The R 2 for our model was 0.456, indicating that 45.6% of the variability in depressive symptoms can be explained by the model. CONCLUSION This study suggested that neuroticism, active coping, and use of social support play important role in mediating the effects of childhood abuse on adult depressive symptoms.

Abstract
OBJECTIVES To assess the association between gender and suicide attempt/death and identify gender-specific risk/protective factors in adolescents/young adults. METHODS Systematic review (5 databases until January 2017). Population-based longitudinal studies considering non-clinical populations, aged 12-26 years, assessing associations between gender and suicide attempts/death, or evaluating their gender risk/protective factors, were included. Random effect meta-analyses were performed. RESULTS Sixty-seven studies were included. Females presented higher risk of suicide attempt (OR 1.96, 95% CI 1.54-2.50), and males for suicide death (HR 2.50, 95% CI 1.8-3.6). Common risk factors of suicidal behaviors for both genders are previous mental or substance abuse disorder and exposure to interpersonal violence. Female-specific risk factors for suicide attempts are eating disorder, posttraumatic stress disorder, bipolar disorder, being victim of dating violence, depressive symptoms, interpersonal problems and previous abortion. Male-specific risk factors for suicide attempt are disruptive behavior/conduct problems, hopelessness, parental separation/divorce, friend's suicidal behavior, and access to means. Male-specific risk factors for suicide death are drug abuse, externalizing disorders, and access to means. For females, no risk factors for suicide death were studied. CONCLUSIONS More evidence about female-specific risk/protective factors of suicide death, for adolescent/young adults, is needed.

Child maltreatment, psychopathological symptoms, and onset of diabetes mellitus, hypothyroidism and COPD in adulthood. J Affect Disord 2018; 241:80-85. [PMID: 30099267 DOI: 10.1016/j.jad.2018.07.085] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Revised: 07/11/2018] [Accepted: 07/31/2018] [Indexed: 11/23/2022]
Abstract
BACKGROUND The aim of this study was to assess the associations between child maltreatment (CM), psychopathological symptoms, and onset of diabetes mellitus, hypothyroidism (i.e., low metabolism), and chronic bronchitis/emphysema/COPD in adulthood. METHODS The present analysis used cross-sectional data collected in 2007-2008 within the Tromsø Study, Norway (N = 12,981). CM was measured with a single item, and self-reported information on psychopathological symptoms and physical health outcomes was used. The associations between CM, psychopathological symptoms, and physical health outcomes were assessed with linear and Poisson regression models. Mediation was assessed with difference-in-coefficients method. RESULTS In the fully-adjusted models, CM was associated with higher levels of anxiety and depression, psychological distress, difficulty in sleeping, insomnia, and use of sleeping pills and antidepressants in adulthood (p < 0.05). Moreover, CM was associated with a more than two-folds increased risk of consultation with psychiatrist (p < 0.001), a 26% increased risk of forgetfulness (p < 0.001), a 15% increased risk of decline in memory (p < 0.001), and a 96% increased risk of psychiatric problems (p < 0.001) over the course of life. In the fully-adjusted models, CM was associated with a 27-82% increased risk of physical health outcomes in adulthood (p < 0.05). Indicators of psychopathological symptoms significantly (p < 0.05) mediate the associations between CM and physical health outcomes. LIMITATIONS The design of this study is cross-sectional, and all measures are self-reported. CONCLUSION The associations between retrospectively-reported CM and physical health outcomes in adulthood are partially driven by psychopathological symptoms in adulthood.

Abstract
Several researchers have raised the concern that the cross-sectional association of retrospectively reported childhood adversity with self-reported onset of asthma and chronic bronchitis in adulthood may be confounded, as well as mediated by an individual's mental health. The aim of this study was to assess the effect of retrospectively reported childhood adversity on self-reported onset of asthma and chronic bronchitis in adulthood, independent of potential confounding and mediating variables (including respondent's mental health). We used data collected in 2007-2008 within the framework of the Tromsø Study (N = 12,981), a representative study of adult men and women in Norway. The associations of childhood adversity with asthma and chronic bronchitis were assessed with Poisson regression models. Relative risks (RR) and 95% confidence intervals (CI) were estimated with bias-corrected bootstrapping. Childhood adversity was associated with a 9% increased risk of asthma (RR = 1.09, 95% CI: 1.02, 1.16) and a 14% increased risk chronic bronchitis (RR = 1.14, 95% CI: 1.03, 1.26) in adulthood, independent of age, sex, parental history of psychiatric problems/asthma/dementia, education, smoking, social support, and respondent's mental health. Controlling for indicators of respondent's mental health reduced the strength of associations of childhood adversity with asthma and chronic bronchitis; however, the associations were still present in the same direction (p < .05). These findings suggest that the association of retrospectively reported childhood adversity with asthma and chronic bronchitis is independent of respondent's mental health. We recommend controlling for indicators of the respondent's mental health to assess an unbiased association of retrospectively measured childhood adversity with self-reported asthma and chronic bronchitis.

Leisure time physical activity and incident use of prescription tranquilizers: A longitudinal population-based study. J Affect Disord 2018; 238:327-335. [PMID: 29902737 DOI: 10.1016/j.jad.2018.06.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 05/13/2018] [Accepted: 06/04/2018] [Indexed: 12/16/2022]
Abstract
OBJECTIVE Physical inactivity is a major public health problem associated with an increased risk of several psychiatric and physical conditions. This study investigated the association between leisure time physical activity (PA) and incident use of prescription tranquilizers in a regionally representative and prospective cohort. METHODS A total of 4043 men and women (mean age: 61.3 years; 57% women) from the Tromsø Study were followed for six years. Leisure time PA was captured at baseline. Psychiatric morbidity was measured by use of prescription tranquilizers, captured at both baseline and follow-up. Leisure time PA at baseline was used as a predictor of subsequent (incident) use of prescription tranquilizers. We used multinomial regression models and Poisson regression models to estimate relative risk-ratios (RRRs), and relative risks (RRs), respectively, and their corresponding 95% confidence intervals (CIs). RESULTS In the fully-adjusted model, accounting for socio-demographic factors, parental history of psychopathology, years of education, smoking, respondent's psychopathology at baseline, and occupational PA, a lower leisure time PA conferred a 41% increased risk of incident use of prescription tranquilizers at follow-up (RR = 1.41, 95% CI: 1.09, 1.83; p = 0.010). CONCLUSIONS These findings suggest that physical inactivity increases the risk of psychiatric morbidity (albeit, measured via use of prescription tranquilizers). Future regionally representative and longitudinal research is required to confirm/refute our findings and explore underlying mechanisms.

Sheikh MA. Coloring of the past via respondent's current psychological state, mediation, and the association between childhood disadvantage and morbidity in adulthood. J Psychiatr Res 2018; 103:173-181.

Abstract
OBJECTIVE Many researchers view retrospective reports with skepticism. Indeed, the observed association between retrospectively-reported childhood disadvantage (CD) and morbidity in adulthood has been criticized as an artefactual correlation driven by the psychological state of the respondent at the time of reporting (current psychological state). The aim of this study was to assess the role of current psychological state in the association between childhood disadvantage and morbidity in adulthood. METHODS The present analysis used cross-sectional data collected in 2007-2008 within the framework of the Tromsø Study (N = 10,765), a representative study of adult men and women in Norway. The association between CD and the physical health outcomes heart attack, angina pectoris, chronic bronchitis/emphysema/COPD, diabetes mellitus, hypothyroid/low metabolism, migraine, hypertension, and comorbidity (i.e., the sum of these physical health outcomes) was assessed with Poisson regression models. Relative risks (RR) and 95% confidence intervals (CI) were estimated. A wide range of indicators of respondents' current psychological state were included in the models to assess the % attenuation in estimates. RESULTS CD was associated with an increased risk of heart attack, angina pectoris, chronic bronchitis/emphysema/COPD, diabetes mellitus, hypothyroid/low metabolism, migraine, hypertension, and comorbidity (p < 0.05), independent of respondents' current psychological state. A sizeable proportion (23-42%) of the association between CD and physical health outcomes was driven by recall bias or mediation via respondents' current psychological state. Controlling for indicators of current psychological state reduced the strength of associations between CD and physical health outcomes; however, the independent associations remained in the same direction. CONCLUSION The association between retrospectively-reported CD and physical health outcomes in adulthood is not driven entirely by respondent's current psychological state.

Abstract
Objective This study investigated the effect of the number of close friends (within and outside of social housing neighbourhoods) on the emotional well-being of men and women in social housing neighbourhoods in China. Methods Data (n = 535) were collected in 13 social housing neighbourhoods in Guangzhou from September to December 2013 using the random sample method. The t-test, chi-square test, and linear regression analysis were used to analyse the factors influencing residents’ emotional well-being. Results Having a greater number of close friends living within the social housing neighbourhood had a significantly positive association with the respondents’ emotional well-being (regression coefficient = 0.473). The number of close friends living in nearby neighbourhoods was only positively related to women’s emotional well-being (coefficient = 0.433). Conclusions These results highlight the importance of friendship for residents’ emotional well-being. Especially for women, friendship outside the social housing neighbourhood is essential for good mental health. This conclusion is based on analysis of cross-sectional data, and reflects the directionality of social associations. The mental health of the poor warrants greater attention in China.
