Dimensions of adversity in association with adolescents' depression symptoms: Distinct moderating roles of cognitive and autonomic function.

ABSTRACT: Exposure to adverse events is prevalent among youths and robustly associated with risk for depression, particularly during adolescence. The Dimensional Model of Adversity and Psychopathology (DMAP) distinguishes between adverse events that expose youths to deprivation versus threat, positing unique mechanisms of risk (cognitive functioning deficits for deprivation, and altered fear and emotion learning for threat) that may require different approaches to intervention. We examined whether deprivation and threat were distinctly associated with behavioral measures of cognitive processes and autonomic nervous system function in relation to depression symptom severity in a community sample of early adolescents (n = 117; mean age 12.73 years; 54.7% male). Consistent with DMAP, associations between threat and depression symptoms, and between economic deprivation and depression symptoms, were distinctly moderated by physiological and cognitive functions, respectively, at baseline but not follow-up. Under conditions of greater cognitive inhibition, less exposure to deprivation was associated with lower symptom severity. Under conditions of blunted resting-state autonomic response (electrodermal activity and respiratory sinus arrhythmia), greater exposure to threat was associated with higher symptom severity. Our findings support the view that understanding risk for youth depression requires parsing adversity: examining distinct roles played by deprivation and threat, and the associated cognitive and biological processes.

Project description:Pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-? (TNF-?), are thought to play a fundamental role in the pathogenesis of depression within a subset of individuals. However, the involvement of IL-1? has not been as consistently linked to depression, possibly owing to difficulties in detecting this cytokine in blood samples or that changes in circulating levels might only be apparent in a subgroup of patients who have experienced early-life adversity. From this perspective, the association between early-life adversity and depressive illness might depend on genetic variants regulating IL-1? activity. Considering the inflammatory-depression link, and that women are twice as likely to experience depression compared to men, the current study (N = 475 university students) examined the moderating role of three independent cytokine single nucleotide polymorphisms (SNPs; IL-1? rs16944, IL-6 rs1800795 SNP, TNF-? rs1800629) in the relationship between early-life adversity and depressive symptoms, and whether these relations differed between males and females. The relation between childhood adversity and depressive symptoms was moderated by the IL-1? SNP, and further varied according to sex. Specifically, among females, higher childhood maltreatment was accompanied by elevated depressive symptoms irrespective of the IL-1? SNP, but among males, this relationship was particularly pronounced for those carrying the GG genotype of the IL-1? SNP. These findings suggest that, in the context of early life adversity, genetic variations of IL-1? functioning are related to depressive symptomatology and this may vary among males and females. The present study also, more broadly, highlights the importance of considering the confluence of experiential factors (e.g., early life adversity) and personal characteristics (e.g., sex and genetics) in understanding depressive disorders, an approach increasingly recognized in developing personalized treatment approaches to this illness.

Project description:BackgroundLittle is known about the association between stressors (especially positive stressors) during pregnancy and postpartum depression and anxiety.AimsWe investigated the association between positive and negative stress events during different stages of pregnancy and postpartum mental health outcomes among low-income pregnant women with symptoms of anxiety in Pakistan and evaluated whether an intervention based on cognitive-behavioural therapy (CBT) had a regulatory effect.MethodsParticipants were 621 pregnant Pakistani women with mild anxiety. Using the Pregnancy Experience Scale-Brief Version, six scores were created to assess positive and negative stressors. We performed a multivariate linear regression to examine whether these six scores, measured both at baseline and in the third trimester, were associated with postpartum anxiety and depressive symptoms. The effect of the intervention on this relationship was examined by adding an interaction term to the regression model.ResultsHassles frequency measured in the third trimester was positively associated with depression (B=0.22, 95% confidence interval (CI): 0.09 to 0.36) and anxiety (B=0.19, 95% CI: 0.08to 0.30). At the same timepoint, uplifts intensity was negatively associated with symptoms of depression (B=-0.82, 95% CI: -1.46 to -0.18) and anxiety (B=-0.70, 95% CI: -1.25 to -0.15), whereas hassles intensity was positively related to symptoms of depression (B=1.02, 95% CI: 0.36 to 1.67) and anxiety (B=0.90, 95% CI: 0.34 to 1.47). The intensity ratio of hassles to uplifts reported in the third trimester was positively related to both depression (B=1.40, 95% CI: 0.59 to 2.20) and anxiety (B=1.26, 95% CI: 0.57 to 1.96). The intervention strengthened the overall positive effects of uplifts and the negative effects of hassles. Pregnancy experiences at baseline during early pregnancy to mid-pregnancy were not associated with mental health outcomes.ConclusionsStressors in the third trimester but not earlier in pregnancy were associated with postpartum symptoms of anxiety and depression. The CBT intervention modified the association between pregnancy stressors and postpartum mental health outcomes. Programmes that promote positive experiences and reduce negative experiences, especially in late pregnancy, may mitigate postpartum mental health consequences.Trial registration numberNCT03880032.

Project description:BackgroundChild abuse is widespread around the world, and one continent with particularly high rates is Africa. Research in high- and middle-income countries shows the cascading effect of parental history of child abuse and neglect on adolescents' maltreatment and, in turn, on mental health problems. This cascade has been reported in young children but has rarely been studied in parent-adolescent dyads or in low-income countries (LICs). The goal of this study was to test intergenerational associations of child abuse and neglect and to examine how these experiences are in turn associated with youth anxiety and depression in an LIC.MethodsA total of 231 adolescents (age: 13-21 years) and 185 of their parents (n = 90 fathers and n = 95 mothers) were recruited from secondary schools in Addis Abeba, Ethiopia. Using a cross-sectional design, participants completed a set of questionnaires assessing child maltreatment (in adolescence and own past history in parents), parental psychological distress, youth depression and anxiety, and sociodemographic factors.ResultsThe frequencies of child maltreatment exposure were 68% for adolescents and 65% for their parents (when they were a child). Fifty-one percent and 42% of adolescents had borderline to clinical levels of anxiety and depression symptoms, respectively. Adolescents of parents with a history of child abuse and neglect also reported higher exposure to maltreatment themselves (p < 0.001). Current paternal, but not maternal, psychological distress mediated this intergenerational association of maltreatment experiences (95% CI [1.164, 9.467]). We further found parents' psychological distress to be a significant moderator of the indirect pathways of the intergenerational effect of child maltreatment on adolescents' anxiety and depression (95% CI [- 0.770, - 0.012]).ConclusionsWe found child maltreatment to be intergenerationally associated, and this effect subsequently affected adolescents' anxiety and depression through different pathways supporting the cascading effects across generations. Intervention plans may be effective through an array of possible indirect pathways and encourage the implementation of multiple access points to facilitate change in the lives of affected youth in Africa.
