Socioeconomic Status, Amygdala Volume, and Internalizing Symptoms in Children and Adolescents.

ABSTRACT: The associations among socioeconomic disadvantage, amygdala volume, and internalizing symptoms in children and adolescents are unclear and understudied in the extant literature. In this study, we examined associations between socioeconomic status (SES) and amygdala volume by age across childhood and adolescence to test whether socioeconomic disadvantage would be associated with larger amygdala volume at younger ages but with smaller amygdala volume at older ages. We then examined whether SES and amygdala volume were associated with children's levels of anxiety and depression. Participants were 3- to 21-year-olds from the Pediatric Imaging, Neurocognition, and Genetics study (N = 1,196), which included structural magnetic resonance imaging. A subsample (n = 327; 7-21 years of age) completed self-report measures of anxiety and depression. Lower family income and parental education were significantly associated with smaller amygdala volume in adolescence (13-21 years) but not significantly associated with amygdala volume at younger ages (3-12 years). Lower parental education, but not family income, was significantly associated with higher levels of anxiety and depression, even after accounting for family history of anxiety/depression. Smaller amygdala volume was significantly associated with higher levels of depression, even after accounting for parental education and family history of anxiety/depression. These findings suggest that associations between SES and amygdala structure may vary by age. In addition, smaller amygdala volume may be linked with an increased risk for depression in children and adolescents.

Project description:BackgroundIn the United States, due to residential segregation, racial minorities and families with low socioeconomic status (SES) tend to live in less safe neighborhoods than their White and high SES counterparts. As such, in the US, race and SES closely correlate with neighborhood safety. Due to the high chronicity of stress in unsafe neighborhoods, perceived neighborhood safety may be a mechanism through which race and SES are linked to children's mental health. Simultaneously, race and SES may alter the effects of perceived neighborhood safety on children's mental health.AimTo explore racial and SES differences in the effects of neighborhood safety on children's internalizing symptoms, we compared racially and SES diverse groups of American children for the effects of parents' perceived neighborhood safety on children's internalizing symptoms.MethodsThis cross-sectional study included 10484 children from the Adolescent Brain Cognitive Development (ABCD) study. Mixed-effects regression was used for data analysis. The predictor variable was parents' perceived neighborhood safety which was treated as a continuous measure. The primary outcome was children's internalizing symptoms reported by children. Race, parental education, household income, and family structure were moderators.ResultsOverall, the parents' high neighborhood safety was associated with lower levels of internalizing symptoms in children. Race and household income showed statistically significant interactions with subjective neighborhood safety on children's internalizing symptoms. Parents' perceived neighborhood safety showed a stronger inverse association with children's internalizing symptoms for Black than White families. Parents' perceived neighborhood safety showed a stronger inverse association with children's internalizing symptoms for high income than low-income families. Parental education or family structure did not show any significant interaction with parents' perceived neighborhood safety on children's internalizing symptoms.ConclusionThe degree to which neighborhood safety may be associated with children's internalizing symptoms may depend on race and household income. Some of the effects of race and SES on children's mental health outcomes may be due to interactions with contextual factors such as neighborhood safety. More research is needed on why and how diverse racial and SES groups differ in the association between perceived neighborhood safety and children's well-being.

Project description:Ecological stress during adolescent development may increase the sensitivity to negative emotional processes that can contribute to the onset and progression of internalizing behaviors during preadolescence. Although a small number of studies have considered the link among the relations between ecological stress, amygdala reactivity, and internalizing symptoms in childhood and adolescence, these studies have largely been small, cross-sectional, and often do not consider unique roles of parenting or sex. In the current study, we evaluated the interrelations between ecological stress, amygdala reactivity, subsequent internalizing symptoms, and the moderating roles of parenting and sex among 9- and 10-year-old preadolescents from the Adolescent Brain Cognitive Development (ABCD) Study ®. A subset of participants who met a priori quality control criteria for bilateral amygdala activation during the EN-back faces versus places contrast (N = 7,385; Mean Age = 120 months, SD = 7.52; 49.5% Female) were included in the study. A confirmatory factor analysis was performed to create a latent variable of ecological stress, and multiple structural equation models were tested to evaluate the association among baseline ecological stress and internalizing symptoms one year later, the mediating role of amygdala reactivity, and moderating effects of parental acceptance and sex. The results revealed a significant association between ecological stress and subsequent internalizing symptoms, which was greater in males than females. There was no association between amygdala reactivity during the Faces versus Places contrast and ecological stress or subsequent internalizing symptoms, and no mediating role of amygdala or moderating effect of parental acceptance on the association between ecological stress and internalizing symptoms. An alternative mediation model was tested which revealed that there was a small mediating effect of parental acceptance on the association between ecological stress and internalizing symptoms, demonstrating lower internalizing symptoms among preadolescents one year later. Given the lack of association in brain function, ecological stress and internalizing symptoms in preadolescents in this registered report, effects from comparable small studies should be reconsidered in larger samples.
