Parental separation in childhood as a risk factor for depression in adulthood: a community-based study of adolescents screened for depression and followed up after 15 years

Atypical Brain Aging and Its Association With Working Memory Performance in Major Depressive Disorder

BACKGROUND

Patients with major depressive disorder (MDD) can present with altered brain structure and deficits in cognitive function similar to those seen in aging. However, the interaction between age-related brain changes and brain development in MDD remains understudied. In a cohort of adolescents and adults with and without MDD, we assessed brain aging differences and associations through a newly developed tool that quantifies normative neurodevelopmental trajectories.

METHODS

A total of 304 participants with MDD and 236 control participants without depression were recruited and scanned from 3 studies under the Canadian Biomarker Integration Network for Depression. Volumetric data were used to generate brain centile scores, which were examined for 1) differences between participants with MDD and control participants; 2) differences between individuals with versus without severe childhood maltreatment; and 3) correlations with depressive symptom severity, neurocognitive assessment domains, and escitalopram treatment response.

RESULTS

Brain centiles were significantly lower in the MDD group than in the control group. Brain centile was also significantly correlated with working memory in the control group but not the MDD group. No significant associations were observed between depression severity or antidepressant treatment response and brain centiles. Likewise, childhood maltreatment history did not significantly affect brain centiles.

CONCLUSIONS

Consistent with previous work on machine learning models that predict brain age, brain centile scores differed in people diagnosed with MDD, and MDD was associated with differential relationships between centile scores and working memory. The results support the notion of atypical development and aging in MDD, with implications for neurocognitive deficits associated with aging-related cognitive function.

Parental absence as an adverse childhood experience among young adults in sub-Saharan Africa

BACKGROUND

Parental absence in childhood has been associated with multiple negative consequences, such as depression and anxiety in young adulthood.

OBJECTIVE

To assess whether parental absence for six months or more in childhood is associated with poor mental health and substance use in young adulthood and whether parental absence accounts for additional variance beyond those explained by other adverse childhood experiences (ACEs) among youth in sub-Saharan Africa.

PARTICIPANTS AND SETTINGS

We used combined Violence Against Children and Youth Survey (VACS) data from Cote d'Ivoire (2018), Lesotho (2018), Kenya (2019), Namibia (2019), and Mozambique (2019). Analyses were restricted to 18-24-year-olds (nf = 7699; nm = 2482).

METHODS

We used logistic regression to examine sex-stratified relationships between parental absence in childhood (defined as biological mother or father being away for six months or more before age 18) and mental health problems and substance use and whether parental absence explained additional variance beyond those explained by other ACEs.

RESULTS

In sub-Saharan Africa, parental absence in childhood was common (30.5 % in females and 25.1 % in males), significantly associated with poor mental health and substance use among females and males and accounted for additional variance beyond those explained by conventional ACEs. For example, after controlling for study covariates and other ACEs, females who experienced any parental absence had 1.52 (95 % CI = 1.02-2.26) higher odds of experiencing moderate/serious psychological distress compared with those who did not.

CONCLUSION

The observed association between parental absence and poor mental health suggests that this experience has significant adverse consequences and merits consideration as an ACE.

The impact of comorbid premenstrual syndrome or premenstrual dysphoric disorder on the clinical characteristics of bipolar disorder among Han Chinese women

Bipolar disorder (BD) is commonly comorbid with premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD). However, little is known about their relationship. This study aimed to assess the impact of comorbid PMS or PMDD on the clinical characteristics of BD. A cross-sectional study was conducted on 262 women with BD. PMS and PMDD were screened with the Premenstrual Symptoms Screening Tool (PSST). Symptomatic features were assessed with Hamilton Depression Scale (HAMD), Young Mania Rating Scale (YMRS), and atypical features by the depressive episode section of SCID-I/P. The rates of PMS and PMDD among BD were 57.6% and 20.6% according to PSST. No significant difference in the rates of PMS and PMDD was found between BD I, BD II, and BD-NOS. Compared to BD patients without PMS or PMDD, patients with comorbid BD and PMS or PMDD were younger, more educated, had a higher risk of OCD, had an earlier age of onset, scored higher on HAMD-17 and its sub-scale of anxiety/somatization, cognitive deficit, psychomotor retardation, and were more likely to have increased appetite and leaden paralysis. In addition, patients with comorbid BD and PMDD were less likely to experience traumatic life events, more likely to have family history of mental disorders and have inflammatory or autoimmune disease, scored higher on HMAD-17, particularly in its sub-scale of anxiety/somatization, cognitive deficit, psychomotor retardation, and sleep disturbance. Compared with BD without PMS or PMDD, BD with PMS or PMDD might be a specific subtype of BD characterized with earlier onset age, heavier genetic load, increased symptom severity, and atypical features.

Depressive symptoms among adolescents in six sub-Saharan African countries: A pooled analysis of associated factors

There is a need to identify risk factors, including nutrition-related factors, for depressive disorders among sub-Saharan African (SSA) adolescents. We examined the association of multiple measures with depressive symptoms among adolescents living across six SSA countries. Building on previous analyses, we used data from a cross-sectional study conducted from 2015 to 2017 among adolescents aged 10-19 years in six SSA countries (N = 7512). Depressive symptoms were defined as highest tertile of the 6-item Kutcher Adolescent Depression Scale score. Using mixed-effects Poisson regression models, we pooled data across sites and examined the association of sociodemographic, nutrition, and other indices with depressive symptoms. We additionally assessed effect modification by sex, age, and school-going status. We observed higher risk of depressive symptoms among girls (adjusted risk ratio [RR]: 1.29, 95 % confidence interval [95 % CI]: 1.05-1.58, P = 0.016), older adolescents (RR for 18-19 years: 1.59, 95 % CI: 1.44-1.76, P < 0.001), and adolescents experiencing bullying (RR: 1.43, 95 % CI: 1.26-1.62, P < 0.001) or violence (RR: 1.34, 95 % CI: 1.24-1.45, P < 0.001). Adolescents experiencing food insecurity also had a higher risk of depressive symptoms (RR: 1.90, 95 % CI: 1.64-2.19, P < 0.001) along with those consuming ≥ 5 servings of fruit and vegetables per day (RR: 1.18, 95 % CI: 1.03-1.34, P = 0.015); conversely, those who consumed grains, roots and tubers in the past day were at decreased risk (RR: 0.73, 95 % CI: 0.69-0.77, P < 0.001). There was no strong evidence of effect modification of associations. This study reinforces the potential role of multiple sociodemographic and nutrition-related measures on risk of depressive symptoms in these populations.

Mental health status and stressful life events among postgraduate nursing students in Cyprus: a cross-sectional descriptive correlational study

BACKGROUND

Despite prior evidence supporting the association between stressful life events and mental health status, there are limited data on the number and severity of stressful life events and their effects on university students' mental health status. Therefore, the present study aimed to: (a) examine mental health status and subsequent predictors of clinically significant mental distress symptoms, (b) estimate the number and severity of stressful life events, and (c) explore the associations between mental health status, stressful life events (number and severity) and sociodemographic characteristics.

METHODS

This study was descriptive, cross-sectional, and correlational with internal comparisons. A convenience sample of 90 Master of Science in nursing and midwifery students, participated in the study. Participants with a General Health Questionnaire-28 (GHQ-28) total score ≥ 24 were considered to have clinically significant mental distress symptoms. Descriptive and inferential statistics were evaluated, and Pearson's chi-square test for group differences was used to analyse the data. Analysis of variance and t-tests were used for comparisons between two or more groups, and regression analyses were employed to identify the predictors of GHQ-28 scores and clinical mental distress symptoms.

RESULTS

The final sample comprised 90 students (response rate: 97.8%), 33 (36.7%) of whom reported clinically significant symptoms of mental distress. Students with divorced parents [29.92 (± 10.62), p < .05] scored high on the GHQ-28. Participants who had low/no satisfaction with the education system posted higher scores than participants who had high/very high satisfaction [24.82 (± 11.68) vs. 17.93 (± 9.78), p < .05]. In the subscale measuring depressive symptoms, there was a statistically significant gender difference, with men reporting higher scores than females. [3.0± (3.69) vs. 1.60 (± 2.42), p = .034]. In multiple analyses of sociodemographic characteristics and those who scored higher on the Life Events Scale for Students (LESS) scale (≥ 340), the loss of parent/s was associated with the total GHQ-28 score (B=-17.046, p < .001). In multiple analyses, chronic physical disorders or disabilities and numerous stressful life events among students (≥ 8 events) were correlated with higher overall GHQ-28 scores (B = 15.232, p < .005).

CONCLUSION

The high frequency of clinical symptoms of mental distress among postgraduate university nursing students and their correlation with stressful life events highlights the need for university counselling services to provide psychological support strategies to students.

Childhood adversities and mental health problems: A systematic review

The number of mental health problems in children and adolescents has been increasing. One of the causes of mental health problems is trauma in the family, such as childhood adversities. The aim of this study was to review the relationship between childhood adversities and mental health problems. The method in this study was a systematic review using three databases: CINAHL, PubMed, and SCOPUS. The results of the review were reported according to the PRISMA guidelines. The keywords used in this study were mental health or mental illness or mental disorder or psychiatric illness AND adolescents or teenagers or teenagers or youth AND parental divorce or parental separation OR parental death or parental loss or parentally bereaved. The inclusion criteria for the articles were English language and published from 2017 to 2021. This study recorded 477 articles, screened according to the topic, and then the final articles were 35. The results of the systematic review showed evidence that childhood adversities were related to mental health problems according to the ICD-10 diagnosis, ADHD and personality disorders, depression, post-traumatic, smoking behavior, and alcohol abuse, and distress. Interventions for children with childhood adversities were needed to prevent mental health disorders.

The mediating pathways between parental separation in childhood and offspring hypertension at midlife

Social life course determinants of adult hypertension are relatively unknown. This paper examines how parental separation before age 10 relates to hypertension at age 46. Adjusting for parental confounders and considering the role of adult mediators, we aim to quantify unexplored mediating pathways in childhood using prospectively collected data. Data from the 1970 British Birth Cohort Study are utilised. Hypertension is measured by health care professionals at age 46. Potential mediating pathways in childhood include body mass index (BMI), systolic and diastolic blood pressure, illness, disability, family socioeconomic status (SES) and cognitive and developmental indicators at age 10. Additionally, we explore to what extent childhood mediators operate through adult mediators, including health behaviours, family SES, BMI and mental wellbeing. We also test for effect modification of the relationship between parental separation and hypertension by gender. Nested logistic regression models test the significance of potential mediating variables. Formal mediation analysis utilising Karlson Holm and Breen (KHB) method quantify the direct and indirect effect of parental separation on offspring hypertension at midlife. There was an association between parental separation and hypertension in mid-life in women but not men. For women, family SES and cognitive and behavioural development indicators at age 10 partly mediate the relationship between parental separation and hypertension at age 46. When adult mediators including, health behaviours, family SES, BMI and mental wellbeing are included, the associations between the childhood predictors and adult hypertension are attenuated, suggesting that these childhood mediators in turn may work through adult mediators to affect the risk of hypertension in midlife. We found family SES in childhood, cognitive and behaviour development indicators at age 10, including disruptive behaviour, coordination and locus of control in childhood, to be important mediators of the relationship between parental separation and midlife hypertension suggesting that intervening in childhood may modify adult hypertension risk.

ACE domains and depression: Investigating which specific domains are associated with depression in adulthood

BACKGROUND

The study of adverse childhood experiences (ACEs) has shown deleterious effects throughout adulthood. Little attention, however, is given to specific ACE domains as they relate to mental health outcomes, as most studies use cumulative ACE score models.

OBJECTIVE

The current study disaggregates ACEs domains to investigate their independent effect (while controlling for each other and other demographic covariates) on receiving a depression diagnosis as an adult.

PARTICIPANTS AND SETTING

Data were obtained from the Behavioral Risk Factor Surveillance Survey (BRFSS; N = 52,971).

METHODS

To control and account for the numerical number of ACEs, separate models were run among each ACE score (e.g., those with an ACE score of exactly two, three, etc.). An aggregate model with all participants is also included.

RESULTS

Across all ACE scores, those with a history of family mental illness had the highest likelihood of receiving a depression diagnosis. The second strongest association were those with sexual abuse. No other trends were found among the six other domains. Further, those with a combination of family mental illness and sexual abuse had the highest odds of depression.

CONCLUSIONS

Mental health providers should consider the numerical number of ACEs as well as the specific ACE domains (specifically, family mental illness and sexual abuse). Additionally, this provides evidence for a possible weighting schema for the ACEs scale.

Stressors and Coping Methods of Turkish Adolescents With High and Low Risk of Depression: A Qualitative Study

BACKGROUND

Stress and coping skills are essential factors in the etiology of depression. Understanding the stressors and coping strategies of adolescents in Turkey may help determine the content of the country-specific depression prevention program.

AIMS

The purpose of this study was to understand the stressors of adolescents with a high or low risk of depression and how they coped with these stressors.

METHOD

This descriptive qualitative study was conducted in a high school in western Turkey. The data were collected via semistructured individual interviews. Eleven adolescents with high risk of depression and 10 adolescents with low risk of depression were included in the study. Content analysis technique was used to analyze the data.

RESULTS

The stressors of adolescents and their coping were grouped into three themes: stressors, factors affecting coping strategies of adolescents, and coping. Stressors theme consists of three subthemes: family relationship, peer relationship, and telephone/internet usage. The factors affecting coping strategies of adolescents theme consists of four subthemes: cognitive distortions, self-perception, family relationships, and peer relationships. The coping theme consists of two subthemes: engagement coping and disengagement coping.

CONCLUSIONS

It was determined that adolescents with a high risk of depression had more stressors and used more disengagement-coping techniques. It is recommended that to prevent depression among adolescents, school nurses should take initiatives to strengthen the coping strategies of adolescents with high risk of depression.

The dimensionality of adverse childhood experiences: A scoping review of ACE dimensions measurement

OBJECTIVE

Despite extensive research, the concept of adverse childhood experiences (ACEs) is not fully developed and there is low agreement on how the concept should be defined and measured. The purpose of this study was to 1) identify different conceptual dimensions associated with ACEs, such as timing or frequency; and 2) determine how these dimensions have been operationalized and analyzed to this point, in order to advance the conceptual understanding of ACEs.

METHODS

We conducted a scoping review of empirical journal articles on ACEs published after the original ACE-Study in 1998 to summarize the use of dimensions for the 10 conventional ACE domains. We used a PRISMA methodology to identify articles that assessed at least two of the 10 conventional ACE domains and at least two ACE dimensions. A standardized data extraction spreadsheet was used to record basic article information and specifics on ACE domains and dimensions.

RESULTS

Of 15,417 initial search results, 61 articles met all selection criteria. We identified four primary dimensions used for most ACE domains: frequency, timing, perception, and the role of the perpetrator. Additionally, we found several secondary and domain-specific dimensions, which relate to the intensity of the adverse event.

DISCUSSION

We identified the most commonly used ACE dimensions, but these lack standardized phrasing of items and response options. The inclusion of ACE dimensions may increase the accuracy of the association between ACEs and health outcomes and provide for more tailored treatment plans for people who have experienced ACEs. Future research should include a more comprehensive list of ACE domains and aim to develop a clearly articulated, standardized approach to assessing and analyzing ACE dimensions.

Effects of somatic treatments on suicidal ideation and completed suicides

OBJECTIVE

This work was undertaken to define and characterize the role of currently available somatic treatments in psychiatry in either increasing or reducing the risk for suicide.

METHODS

Members of the Suicide Prevention Task Group of the National Network of Depression Centers performed a literature review of somatic treatments known to increase or reduce the risk for suicide. The reviews ventured to include all relevant information about the risk for both suicide ideation and completed suicides.

RESULTS

Lithium and clozapine are the only two somatic treatments that have high-quality data documenting their antisuicide effects in mood disorders and schizophrenia, respectively. Lithium discontinuation is also associated with increased suicide risk. Ketamine and esketamine may have a small, but immediate, antisuicide effect. Despite the recent Food and Drug Administration approval of esketamine use in depressed suicidal patients, the small disproportional overrepresentation of suicide in subjects who had received esketamine versus placebo (3 vs. 0 among > 3500 subjects) requires ongoing evaluation. The purported antisuicide effect of electroconvulsive therapy is based on low-quality data. The effect of antidepressants is not at all clear. There appears to be direct evidence for antidepressants increasing suicidal ideation and the risk for suicide over the short-term in young people, but indirect (low quality) evidence that antidepressants reduce suicide risk over the long term.

CONCLUSIONS

Clinicians have an expanding pharmacopeia to address suicide potential in their patients. Some of the agents with documented antisuicide effects may also increase suicidality under specific circumstances.

Association between parental divorce and mental health outcomes among Lebanese adolescents: results of a national study

Background

In Lebanon, divorce rates have jumped from nearly 7000 in recent years to 8580 in 2017, an increase of 22.5%, with North Lebanon recording the highest number, followed by Beirut, likely resulting in increased behavioral problems in the offspring of divorced parents. Furthermore, one out of two Lebanese adolescents whose biological parents were divorced, separated, or deceased has a psychiatric disorder. More information regarding the impact of divorce on the mental health of Lebanese adolescents is still missing. The objective of this study was to explore the association between divorce and mental health outcomes, particularly depression, anxiety, and suicidal ideation among Lebanese adolescents.

Methods

A cross-sectional study conducted between January and May 2019 enrolled 1810 adolescents aged 14 to 17 years, using a simple randomization method to choose schools. A proportionate number of schools was selected from each of the five Lebanese Mohafazat (Beirut, Mount Lebanon, North, South, and Beqaa), based on the list of the Ministry of Education and Higher Education. A total of 18 private schools were approached; two declined, and 16 accepted to participate.

Results

The mean age of participants was 15.42 ± 1.14 years, with 53.3% females. After adjustment for the covariates (age, sex, and house crowding index), the results showed that adolescents whose parents are separated compared to living together had more social fear (Standardized Beta (SB = 0.270) and avoidance (SB = 0.188), higher depression (SB = 0.045), and higher suicidal ideation (SB = 0.370).

Conclusion

Our findings reveal that teens with divorced parents had higher social fear and avoidance, depression, and suicidal ideation, highlighting the need for adequate prevention programs to support both children and parents during this emotionally difficult period.

The Effect of Early Traumatic Experiences on Attachment Styles in Sexual Gender Minority Individuals

PURPOSE

This study was carried out to specify the attachment characteristics of sexual gender minority individuals and to determine the effects of childhood traumatic experiences on attachment styles.

DESIGN AND METHODS

A descriptive cross-sectional study was conducted on 141 sexual gender minority individuals from 2016 to 2017.

FINDINGS

The number of childhood physical and sexual trauma episodes was found to be high in sexual minorities; in particular, the traumatized narratives were found to be associated with an avoidant attachment style (p > 0.05).

PRACTICE IMPLICATIONS

The study results may contribute to healthcare professionals' understanding of childhood trauma as it relates to sexual identity development and attachment disorders sexual identity development and attachment disorders.

Parental age and risk of depression: A nationwide, population-based case-control study

BACKGROUND

The global prevalence of depression has increased in recent decades and so has the average age of parenthood. Younger and older parental age have been associated with several mental disorders in their offspring, but the associations for depression have been inconsistent.

METHODS

This study comprised 37,682 singleton births in Finland from 1987- 2007. The subjects were living in Finland at the end of 2012 and had a depressive disorder recorded in the Care Register for Health Care. We also randomly identified 148,795 controls from the Population Register. When missing obsevations excluded the sample was N_cases=18,708 and N_controls=77,243. The results were adjusted for the parents' psychiatric history, depression history, marital status and place of birth, the mothers' maternal socioeconomic status, smoking during pregnancy and previous births and the children's birth weight.

RESULTS

We found a U-shaped association between offspring depression and the age of both parents. The highest odds of depression occurred when the fathers were aged 50 plus years (adjusted Odds Ratio (ORa) 1.51, 95% CI 1.23-1.86) and the mothers were under 20 (ORa 1.44, 95% CI 1.29-1.60) compared to the reference category of parents aged 25-29 years.

LIMITATIONS

The study was limited to depression diagnosed by specialised health care services and had a relatively short follow-up period. Some data were missing and that could lead to risk estimation biases.

CONCLUSION

Diagnosed depression was higher among the offspring of younger and older parents. The results suggest that the age of the parent is etiologically associated with offspring depression.

Alcohol Use Disorder and Risk of Suicide in a Swedish Population-Based Cohort

OBJECTIVE

The authors examined the association between alcohol use disorder (AUD) and risk of suicide, before and after accounting for psychiatric comorbidity, and assessed the extent to which the observed association is due to a potentially causal mechanism or genetic and familial environmental confounding factors that increase risk for both.

METHODS

Longitudinal population-wide Swedish medical, criminal, and pharmacy registries were used to evaluate the risk of death by suicide as a function of AUD history. Analyses employed prospective cohort and co-relative designs, including data on 2,229,880 native Swedes born between 1950 and 1970 and observed from age 15 until 2012.

RESULTS

The lifetime rate of suicide during the observation period was 3.54% for women and 3.94% for men with AUD, compared with 0.29% and 0.76% of women and men, respectively, without AUD. In adjusted analyses, AUD remained robustly associated with suicide: hazard ratios across observation periods ranged from 2.61 to 128.0 among women and from 2.44 to 28.0 among men. Co-relative analyses indicated that familial confounding accounted for some, but not all, of the observed association. A substantial and potentially causal relationship remained after accounting for a history of other psychiatric diagnoses.

CONCLUSIONS

AUD is a potent risk factor for suicide, with a substantial association persisting after accounting for confounding factors. These findings underscore the impact of AUD on suicide risk, even in the context of other mental illness, and implicate the time frame shortly after a medical or criminal AUD registration as critical for efforts to reduce alcohol-related suicide.

Parent-youth conflict as a predictor of depression in adulthood: a 15-year follow-up of a community-based cohort

Experiencing conflictual relations with one's parents while growing up has been linked to onset, recurrence, and worse treatment outcome of adolescent depression. While this suggests that significant problems in the parent-youth relationship make depressive disorders more relentless, it is not clear whether this effect lasts into adulthood. Our aim was to examine if major and minor conflict with parents while growing up predicts depression in adulthood in youth with and without a history of depression. We utilized data from the Uppsala Longitudinal Adolescent Depression Study. This community-based cohort was assessed with structured diagnostic interviews both at age 16-17 and at follow-up 15 years later. The analyses included 382 individuals (227 with a history of child or adolescent depression; 155 peers without such a history). Binary logistic regression was used, adjusting for sex, disruptive behavior disorders, and additional family-related adversities. Among individuals with adolescent depression, major conflict with parents was strongly associated with adult depression (adjusted OR 2.28, 95% CI 1.07-4.87). While major conflict with parents was rare among non-depressed controls, a non-significant association of similar magnitude was still observed. Minor conflict, on the other hand, was not significantly associated with adult depression. Overall, conflict with parents did not predict adult anxiety disorders, substance use, suicidal behavior, somatoform disorders, or psychotic disorders. In conclusion, major parent-youth conflict during upbringing seems to be linked with an increased risk of depression in adulthood. These findings underscore the need to consider contextual/familial factors in the prevention and clinical management of early-life depression.

Divorce and conversational difficulties with parents: Impact on adolescent health and self-esteem

Background: Divorce experience (DE) may cause health and self-conceptual problems, but these consequences might also be caused by conflicts and lack of conversational confidence (CC) with one or both parents. We investigated how DE impacted CC and how DE and CC impacted health complaints and self-esteem in a two-year longitudinal cohort study. Methods: The study was performed between 2011 and 2013 among 1225 students in junior high school (aged 11 and 13 years in 2011). We used binary logistic analyses to account for how DE impacted CC, and linear regression analyses to examine how DE and CC impacted on subjective health and self-esteem in 2013. Results: The study revealed that former and recent DEs impacted CC with fathers only. The impact was most evident for the more severe forms of conversational difficulties. DE in itself predicted only self-esteem, and CC with parents mediated this association. CC with both mothers and fathers had strong temporal causal associations with the outcomes two years later. Only CC with fathers impacted changes of the health complaints and self-esteem in full-model residual change analyses. Conclusions: The study proves a sex-specific effect on loss of CC between fathers and children after divorce. The impairment of CC has predictive repercussions on the health and self-conception of adolescents in their middle teenage years. From a public-health perspective, preserving the relation and the confidence between children and their fathers after divorce seems an important task.

Factors associated with depressive symptoms and suicidal ideation and behaviours amongst sub-Saharan African adolescents aged 10-19 years: cross-sectional study

OBJECTIVE

This study aimed to determine the burden of depression, suicidal ideation and suicidal behaviour amongst adolescents at sites in six sub-Saharan African countries and examine associated risk and protective factors.

METHODS

Household-based cross-sectional study involving male and female adolescents ages 10-19 years. A total of 7,662 adolescents from eight sites in six countries participated in the survey. Three sites were urban: Dar es Salaam (Tanzania), Harar (Ethiopia) and Ibadan (Nigeria); five were rural: Dodoma (Tanzania), Iganga/Mayuge (Uganda), Kersa (Ethiopia), Ningo Prampram (Ghana) and Nouna (Burkina Faso). Log-binomials models were used to estimate relative risks and confidence intervals for factors associated with depression and suicidal behaviour. This was supplemented using log-Poisson models as needed.

RESULTS

The prevalence of suicidal behaviour over the last 12 months ranged between 1.2% and 12.4% in the eight sites. Depressive symptoms and suicidal ideation/behaviours were associated with older age, female sex, food insecurity, poor access to health care and substance use. Depression was strongly associated with increased risk of suicidal behaviour at two sites where the multivariate model converged: Harar, Ethiopia (RR = 3.5, 95% CI 1.8, 7.0, P < 0.05) and Ibadan, Nigeria (RR = 3.7, 95% CI 2.2, 6.3, P < 0.0001).

CONCLUSIONS

Depressive symptoms and suicidal behaviour are common amongst sub-Saharan African adolescents at these 8 sites. Most factors associated with depressive symptoms are modifiable and preventable. Routine screening for depressive symptoms in services frequented by adolescents in these and similar communities would be crucial in early detection and prompt intervention.

The association of psychosocial risk factors for mental health with a brain marker altered by inflammation: A translocator protein (TSPO) PET imaging study

Psychiatric disorders associated with psychosocial risk factors, including depression and psychosis, have been shown to demonstrate increased microglia activity. Whilst preclinical studies indicate that psychosocial stress leads to increased levels of microglia in the frontal cortex, no study has yet been performed in humans. This study aimed at investigating whether psychosocial risk factors for depression and/or psychosis would be associated with alterations in a brain marker expressed by microglia, the translocator specific protein (TSPO) in humans. We used [¹¹C]-PBR28 Positron Emission Tomography on healthy subjects exposed to childhood and adulthood psychosocial risk factors (high-risk group, N = 12) and age- and sex-matched healthy controls not exposed to childhood and adulthood psychosocial risk factors (low-risk group, N = 12). The [¹¹C]-PBR28 volume of distribution (V_T) and Distribution Volume Ratio (DVR) were measured in the total gray matter, and frontal, parietal, temporal, occipital lobes. Levels of childhood trauma, anxiety and depression were measured using respectively the Childhood Trauma Questionnaire, State-anxiety questionnaire and Beck Depression Inventory. Compared to the low-risk group, the high-risk group did not exhibit significant differences in the mean [¹¹C]-PBR28 V_T (F(1,20) = 1.619, p = 0.218) or DVR (F(1,22) = 0.952, p = 0.340) on any region. There were no significant correlations between the [¹¹C]-PBR28 V_T and DVRs in total gray matter and frontal lobe and measures of childhood trauma, anxiety and depression. Psychosocial risk factors for depression and/or psychosis are unlikely to be associated with alterations in [¹¹C]-PBR28 binding, indicating that alterations in TSPO expression reported in these disorders is unlikely to be caused by psychosocial risk factors alone.

Relationship Between Adverse Childhood Experience Survey Items and Psychiatric Disorders

CONTEXT

Developmental psychopathology theory suggests a relationship between early childhood adversity and mental disorder.

OBJECTIVE

To examine the relationship between the specific items on the Adverse Childhood Experiences (ACE) survey and the International Classification of Diseases, Tenth Revision (ICD-10) categories of psychiatric diagnoses in a pediatric sample.

DESIGN

The sample included patients enrolled in the Child and Adolescent Addiction Mental Health and Psychiatry Program with both a completed ACE survey and at least 1 diagnosis of record (per admission). These criteria yielded 2 samples for each sex (ACE survey item frequencies and values in collapsed and multiple-admission groups). Data were analyzed employing tetrachoric correlation, hierarchical regression, and polychoric factor analysis.

RESULTS

Hierarchical regression analysis identified that ICD-10 diagnostic categories, except for substance disorders, were not consistently related to ACE total score and tended to reduce the magnitude of the ACE total score in the multiple-admission group. Tetrachoric correlation revealed very low (< 0.4) positive and negative correlations between ICD-10 categories and ACE items in both multiple-admission and collapsed sample groups. Polychoric factor analysis indicated that the ACE survey items and the ICD-10 categories for both sexes were independent, with only the diagnostic ICD-10 category substance disorders being marginally associated with the ACE items factor for females.

CONCLUSION

The nominal relationship between ACE items and ICD-10 diagnostic categories indicates the need to include ACE assessment in advance of differential diagnosis and implementation of conventional mental health interventions for children and adolescents.

The association between low-grade inflammation and the clinical features of bipolar disorder in Han Chinese population

Variety of evidence suggests that low-grade inflammation may be involved in the pathophysiology of bipolar disorder (BD). However, the conclusion regarding the relationship between inflammation and BD has been inconsistent. In this study, we aimed to survey the prevalence of low-grade inflammation in a large Han Chinese population with BD and assess its impact on the clinical features of BD. 430 eligible cases were drawn from patients who were admitted or had ever been admitted for BD to the inpatient service of the psychiatric department of the Third Hospital of Sun Yat-sen University. Subjects with current active physical diseases or white blood count (WBC) >19.0 × 10⁹/L (2 times the upper reference) were excluded. Serum C-reactive protein (CRP) levels and WBC were measured with fast blood sample. Low-grade inflammation was defined as CRP>3 mg/L or WBC > 9.5 × 10⁹/L(the upper reference). Clinical features of BD were collected through semi-structural interview conducted by trained interviewers with background of psychiatric education. If defined as CRP>3 mg/L, the prevalence of low-grade inflammation among BD was 10.1% (41/404), it was positively associated with BMI (p = 0.012), comorbidity of glycolipid metabolic diseases(p = 0.018). After adjusting for BMI, it was found to be positively related to recent suicide attempt (p = 0.03), initiation with (hypo)manic episode(p = 0.047), leaden paralysis (p = 0.037) and family history of mental disorders(p = 0.012), while the association between comorbidity of glycolipid metabolic diseases and low-grade inflammation disappeared (p = 0.330). If defined as WBC > 9.5 × 10⁹/L, the prevalence of low-grade inflammation was 8.1% (33/409), it was positively associated with psychotic features (p = 0.011) and adverse life events before the onset of illness(p < 0.001), but was not significantly influenced by BMI (p = 0.077). A much lower prevalence of low-grade inflammation in BD is found among Han Chinese population than among western population. Low-grade inflammation of different definition impacts differentially on the clinical features of BD.

Uppsala Longitudinal Adolescent Depression Study (ULADS)

PURPOSE

To present the Uppsala Longitudinal Adolescent Depression Study, initiated in Uppsala, Sweden, in the early 1990s. The initial aim of this epidemiological investigation was to study the prevalence, characteristics and correlates of adolescent depression, and has subsequently expanded to include a broad range of social, economic and health-related long-term outcomes and cost-of-illness analyses.

PARTICIPANTS

The source population was first-year students (aged 16-17) in upper-secondary schools in Uppsala during 1991-1992, of which 2300 (93%) were screened for depression. Adolescents with positive screening and sex/age-matched peers were invited to a comprehensive assessment. A total of 631 adolescents (78% females) completed this assessment, and 409 subsequently completed a 15-year follow-up assessment. At both occasions, extensive information was collected on mental disorders, personality and psychosocial situation. Detailed social, economic and health-related data from 1993 onwards have recently been obtained from the Swedish national registries for 576 of the original participants and an age-matched reference population (N≥200 000).

FINDINGS TO DATE

The adolescent lifetime prevalence of a major depressive episode was estimated to be 11.4%. Recurrence in young adulthood was reported by the majority, with a particularly poor prognosis for those with a persistent depressive disorder or multiple somatic symptoms. Adolescent depression was also associated with an increased risk of other adversities in adulthood, including additional mental health conditions, low educational attainment and problems related to intimate relationships.

FUTURE PLANS

Longitudinal studies of adolescent depression are rare and must be responsibly managed and utilised. We therefore intend to follow the cohort continuously by means of registries. Currently, the participants are approaching mid-adulthood. At this stage, we are focusing on the overall long-term burden of adolescent depression. For this purpose, the research group has incorporated expertise in health economics. We would also welcome extended collaboration with researchers managing similar datasets.

Parental separation and parental mental health in childhood and tinnitus and hyperacusis disability in adulthood: a retrospective exploratory analysis

OBJECTIVES

To explore the relationships between parental separation and parental mental health in childhood with tinnitus and hyperacusis disability in adulthood.

DESIGN

Retrospective cross-sectional.

STUDY SAMPLE

The data for consecutive patients who attended a tinnitus and hyperacusis clinic in the UK over a six months period were included (n = 184).

RESULTS

14.7% of patients reported that while they were growing up, their parents were separated or divorced. There were no significant differences in Tinnitus Handicap Inventory (THI) and Hyperacusis Questionnaire (HQ) between patients with and without history of parental separation. About 40.2% reported history of mental health disorders in their parents. The scores on THI and HQ were worse in the group that reported mental health disorders in their parents (p < .01). Parental mental health illness did not significantly relate to THI, however, it was significantly related to the risk of hyperacusis (odds ratio [OR], after adjusting for age and gender: 2.05, p = .026). The adjusted OR for a subgroup of patients with a diagnosis of hyperacusis was 6.7 (p = .011), indicating a stronger relationship for this subgroup.

CONCLUSIONS

Among patients seeking help for their tinnitus and hyperacusis, poor parental mental health was associated with increased hyperacusis disability.

High prevalence of depressive symptoms in a national sample of adults in Indonesia: Childhood adversity, sociodemographic factors and health risk behaviour

BACKGROUND

The aim of this study was to investigate depressive symptoms and their association with sociodemographic factors, stressors and support, including childhood adversity, health status risk and behaviour in Indonesia.

METHOD

In a cross-sectional national population survey in 2014-15 in Indonesia, 31442 adults (mean age 37.3 years, SD = 14.9, age range 15-101 years) responded to the Centers for Epidemiologic Studies Depression Scale (CES-D-10) and various other measures.

RESULTS

Overall, 15.0% of participants reported moderate and 6.9% severe depressive symptoms, or 21.8% moderate or severe depressive symptoms (21.4% among men and 22.3% among women). In multivariable logistic regression among both men and women, sociodemographic factors (younger age, poor subjective economic background, being unemployed, residing in Java and main island groups), stressors (childhood hunger and poor or fair self-rated health status and having experienced disasters), lack of social trust and religiosity, having one or more chronic conditions, tobacco use and soft drink consumption were positively and obesity negatively associated with moderate or severe depressive symptoms.

CONCLUSION

High rates (21.8%) of depressive symptoms were found. Several risk factors including sociodemographic factors such as younger age, stressors, lack of social support, health risk status and behaviour variables were identified which can be utilized in guiding interventions.

Mother-infant separation among mothers with mental illness: An exploratory observational study in Japan

Mother-infant separation may influence child development and behavior problems. We reviewed charts for 3639 female patients to investigate rates, reasons, and predictors for mothers with mental illness being separated from their infants during the first year after childbirth in Japan. Of 77 patients with childbirth, 26 cases (34%) presented with maternal separation. The most common reason was psychiatric hospitalization. Diagnoses of schizophrenia spectrum disorders or mood disorders were independent contributors for maternal separation. Clinicians should pay particular attention to relapse or onset of psychotic or mood disorders during the perinatal period.
