Lifecourse Social Conditions and Racial and Ethnic Patterns of Cognitive Aging

A lifecourse perspective is key for understanding and interpreting racial and ethnic patterns in neuropsychological test performance. In this article, we discuss contextual factors that shape the environmental conditions encountered by racial and ethnic minorities in the United States, in particular African-Americans. These conditions include geographic segregation at the level of regions, metropolitan areas, and neighborhoods; intra- and inter-national migration patterns; socioeconomic position, including financial resources, and occupational and educational opportunities; discrimination; and group resources. Each of these exposures sets in course a cascade of individual mediators that ultimately manifest in neuropsychological outcomes. The physiological and behavioral consequences of these pathways likely accumulate across the lifecourse. We focus on cognitive aging, although the processes discussed here begin in infancy and likely influence cognitive outcomes throughout life from childhood into old age. A lifecourse framework can help inform clinical encounters, neuropsychological research, and surveillance regarding the population prevalence of cognitive impairments.     

Co-Occurring Youth Profiles of Adverse Childhood Experiences and Protective Factors: Associations with Health,Resilience, and Racial Disparities

It is important to understand racial/ethnic differences in adverse childhood experiences (ACEs), given their relationship to long-term physical and mental health, and the public health cost of the significant disparities that exist. Moreover, in order to inform interventions and promote resilience, it is critical to examine protective factors that mitigate the relationship between adversity and poor health. The current study utilized latent transition analyses (LTA) to examine co-occurring profiles of ACEs and protective factors (from school, family, and community contexts) and links to health outcomes among 30,668 Black (10.4%), Latinx (12.3%), and White youth (77.3%) ages 12–17 (52.5% male) who participated in the 2011–12 National Survey of Children's Health (NSCH). Results suggested that greater adversity was associated with worse health, while more access to protective factors was associated with better health. White youth had consistently lower endorsement of ACEs, greater access to protective factors, and better health compared to their Black and Latinx counterparts. Efforts to improve child health and racial/ethnic disparities in research and practice must consider adversity, protective factors, and the systemic inequities faced by racial/ethnic minority youth in the United States.     

Stress in Relation to Anxiety and Depression Among Racial/Ethnic Minority Women: The Differential Impact of Cultural Mismatch on Somatic and Cognitive Symptoms

The study examined the interactive effects of stress and cultural mismatch, as evidenced by low independent self‐construal, in relation to cognitive/somatic symptoms of anxiety and depression among racial/ethnic minority women. Results showed that stress and independent self‐construal work synergistically to differentially affect cognitive, rather than somatic, symptoms of anxiety and depression. Findings highlight the importance of investigating the interplay between stress and contextual factors to improve current treatment models for marginalized groups. El estudio examinó los efectos interactivos del estrés y la discordancia cultural, probados por un bajo autoconcepto independiente, en relación con los síntomas cognitivos/somáticos de la ansiedad y la depresión entre mujeres de minorías raciales/étnicas. Los resultados mostraron que el estrés y el autoconcepto independiente trabajan en sinergia para afectar diferencialmente a los síntomas cognitivos, no así a los somáticos, de la ansiedad y la depresión. Los hallazgos subrayan la importancia de investigar la interacción entre el estrés y los factores contextuales para mejorar los modelos de tratamiento actuales para grupos marginalizados.
