Background

Large-scale cohort and epidemiological studies suggest that PTSD confers risk for dementia in later life but the biological mechanisms underlying this association remain unknown. This study examined this question by assessing the influences of PTSD, APOE ε4 genotypes, DNA methylation, and other variables on the age- and dementia-associated biomarkers Aβ40, Aβ42, GFAP, NfL, and pTau-181 measured in plasma. Our primary hypothesis was that PTSD would be associated with elevated levels of these markers.

Methods

Analyses were based on data from a PTSD-enriched cohort of 849 individuals. We began by performing factor analyses of the biomarkers, the results of which …

Identity shifting represents a common but complex social, behavioral, and cognitive phenomenon. However, some forms of identity shifting originate in response to structural, institutional, and interpersonal marginalization enacted on lower status groups, such as people of color in the United States. The current study investigated ways young adults from diverse ethnic/racial groups discussed shifting to fit in with White Americans (a dominant group) in the United States and their own ethnic/racial group (a minoritized group) and elucidated self-reported motivations for shifting. Participants consisted of 764 young adults (ages = 18–23) recruited from two large public universities in the Southeast and …

Background

Excessive gestational weight gain (EGWG), insufficient prenatal physical activity and sleep, and poor psychological wellbeing independently increase risks for adverse maternal and infant outcomes. A novel approach to mitigate these risks is utilizing peer support in a community-based prenatal intervention. This study assessed the feasibility (acceptability, demand, implementation, and practicality) of a remotely delivered prenatal physical activity intervention called My Baby, My Move + (MBMM +) that aims to increase prenatal physical activity, enhance mood and sleep hygiene, and reduce EGWG.

Methods

Participants were recruited through community organizations, local clinics, and social media platforms in the Fall of 2020 …
