Environmental Conditions to Promote Healthy Childhood Brain/Behavioral Development: Informing Early Preventive Interventions for Delivery in Routine Care

Sociocultural Risk and Resilience in the Context of Adverse Childhood Experiences

Importance

Knowledge about childhood resilience factors relevant in circumstances of marginalization and high numbers of adverse childhood experiences (ACEs) can improve interventions.

Objective

To identify sociocultural resilience factors in childhood that are associated with better young adult mental health in the context of ACEs.

Design, Setting, and Participants

This cohort study examined 4 waves of data from the Boricua Youth Study, which included Puerto Rican children from the South Bronx, New York, and San Juan, Puerto Rico. Participants were aged 5 to 17 years at waves 1 through 3 (2000-2003) and aged 15 to 29 years at wave 4 (2013-2017). Linear and logistic regression models tested the associations of 7 childhood resilience factors and their interaction with ACEs on young adult mental health outcomes. Data were analyzed from June 2021 to October 2023.

Main Outcomes and Measures

Perceived stress, major depressive disorder and/or generalized anxiety disorder (MDD/GAD), and substance use disorder (SUD) in young adulthood.

Results

Among a total 2004 participants, the mean (SD) age at wave 4 was 22.4 (2.9) years; 1024 participants (51.1%) were female, and 980 (48.9%) were male. Positive parent-child relationships and nonparental adult support during childhood were associated with both lower perceived stress (β = -0.14; SE = 0.02; P < .001; β = -0.08; SE = 0.03; P = .003, respectively) and lower odds of MDD/GAD (adjusted odds ratio [aOR], 0.84; 95% CI, 0.73 to 0.97; aOR = 0.81; 95% CI, 0.69 to 0.95, respectively) in young adulthood. Maternal warmth reported during childhood was also associated with lower young adult perceived stress (β = -0.11; SE = 0.02; P < .001). None of the resilience factors were associated with SUD. The resilience factors familism, friendships, and family religiosity were not associated with any of the mental health outcomes. ACEs were associated with poorer mental health outcomes; however, none of the resilience factors exhibited interactions consistent with being protective for ACEs. Unexpectedly, higher family religiosity was associated with more perceived stress in the presence of higher ACEs.

Conclusions and Relevance

The results of this study suggest that promoting positive relationships with adults during childhood may reduce later young adulthood stress and MDD/GAD. However, there is still a need to identify sociocultural childhood protective factors for ACEs. Caution should be taken in assuming what resilience factors are relevant for a given group, as higher family religiosity (one postulated resilience factor) was unexpectedly associated with a stronger, rather than a weaker, association between ACEs and perceived stress in young adulthood.

Early Emotion Development Intervention Improves Mental Health Outcomes in Low-Income, High-Risk Community Children

Children living in poverty and facing related forms of adversity are at higher risk for experiencing concurrent and later psychopathology. Although negative psychological outcomes can be improved by enhancing sensitive and responsive caregiving early in development, interventions targeting the caregiver-child dyad are not readily accessible. The present study investigated the feasibility and effectiveness of delivering a shortened eight-session form of Parent-Child Interaction Therapy-Emotion Development (PCIT-ED) in-person or remotely as an early intervention for 3-6-year-old children (N = 62) at elevated risk for psychopathology who were growing up in low-income communities. Caregiver-child dyads were randomized to eight-sessions of PCIT-ED or online parenting education. Relative to parenting education, children receiving PCIT-ED exhibited lower externalizing symptoms and functional impairment and more positive peer relationships following the intervention. Findings support the effectiveness of this shortened form of PCIT-ED, delivered in-person or remotely, as an early intervention to improve symptoms of psychopathology and functioning in high-risk children living in poverty.Trial registration Clinicaltrials.gov; NCT04399629.

Editorial: Environmental conditions for growing healthy children

The deleterious developmental effects of exposure to early adversity have been well documented in the scientific literature. The finding that poverty in early childhood is among the most robust predictors of a range of poor developmental outcomes has been well known for decades. More recently, evidence that early experiences of poverty and related forms of adversity negatively impact the function and structure of the developing brain have also emerged. Retrospective studies linking poor physical health outcomes to adverse childhood experiences (ACES) highlighted the more global nature of these risk factors to wellbeing and follow-up prospective studies have since confirmed these findings (Brown et al., 2009). Alternatively, it has become increasingly clear that early experiences of stimulation, nurturance, and caregiver support promote positive development outcomes with emerging evidence for tangible impacts on neurodevelopment in humans (Luby et al., 2021). However, the scientific and public health community has yet to synthesize these related bodies of data and develop a plan of action related to their over-reaching and global importance to protecting and promoting childhood health and development more generally despite numerous calls to do just that (Farah, 2018; Luby et al., 2020).
