RESUMO
The lifespan is influenced by adverse childhood experiences that create predispositions to poor health outcomes. Here we propose an allostatic framework of childhood experiences and their impact on health across the lifespan, focusing on Latin American and Caribbean countries. This region is marked by significant social and health inequalities nested in environmental and social stressors, such as exposure to pollution, violence, and nutritional deficiencies, which critically influence current and later-life health outcomes. We review several manifestations across cognition, behavior, and the body, observed at the psychological (e.g., cognitive, socioemotional, and behavioral dysfunctions), brain (e.g., alteration of the development, structure, and function of the brain), and physiological levels (e.g., dysregulation of the body systems and damage to organs). To address the complexity of the interactions between environmental and health-related factors, we present an allostatic framework regarding the cumulative burden of environmental stressors on physiological systems (e.g., cardiovascular, metabolic, immune, and neuroendocrine) related to health across the life course. Lastly, we explore the relevance of this allostatic integrative approach in informing regional interventions and public policy recommendations. We also propose a research agenda, potentially providing detailed profiling and personalized care by assessing the social and environmental conditions. This framework could facilitate the delivery of evidence-based interventions and informed childhood-centered policy-making.
RESUMO
Despite its significant growth over the past fifteen years, research on parental burnout is just beginning to explore the relationships of the syndrome with child behavior. Previous research with adolescents has shown the existence of associations between parental burnout and internalizing and externalizing behaviors in the offspring. The current study is an attempt to (i) replicate this preliminary evidence specifically among Chilean preschool children and (ii) explore the mediating/moderating effects of positive parenting that may be involved in these putative associations. A sample of 383 Chilean mothers participated in this cross-sectional online study. The results confirmed the associations between parental burnout and child internalizing and externalizing behaviors. We also observed that positive parenting was a mediator in the relationship linking parental burnout and the child's internalizing (full mediation) and externalizing (partial mediation) behaviors. Positive parenting also partially mediated the association between the child's externalizing behavior and parental burnout. Our results further suggested that the child's externalizing behavior was possibly a more substantial contributing factor to parental burnout than the child's internalizing behavior.
RESUMO
The COVID-19 pandemic was a source of significant stress due to health and safety concerns and measures to control the virus' spread, such as mobility restrictions. This measure was especially demanding for parents with school aged children, who had to find new work-family balance as their children participate in online education while attempting to work remotely. To evaluate parents' stress trajectories during the pandemic, we conducted Ecological Momentary Assessments (EMAs) during lockdown for 29 days in 68 families in Santiago, Chile. In addition, we evaluated the role of educational level and income, co-parenting, and number of children in parents' stress trajectories. Our results showed that during the first weeks of lockdown expected protective factors (i.e., income and co-parental support) were not able to influence parents' daily stress management. Moreover, parents with higher educational levels reported worse stress adaptation than less educated parents. On the other hand, co-parental conflict was significantly associated with parent's stress. Our study captured an acute response to COVID-19 related challenges. This study contributes to understanding how parents adjust to stress during adverse circumstances such as the COVID-19 pandemic.
