Nighttime blood pressure (BP) and BP dipping (daytime-nighttime BP) are prognostic for cardiovascular disease. When compared with other racial/ethnic groups, Black Americans exhibit elevated nighttime BP and attenuated BP dipping. Neighborhood deprivation may contribute to disparities in cardiovascular health, but its effects on resting and ambulatory BP patterns in young adults are unclear.

Background: Ambulatory blood pressure () monitoring measures nighttime BP and BP dipping, which are superior to in-clinic BP for predicting cardiovascular disease (), the leading cause of death in America. Compared with other racial/ethnic groups, Black Americans exhibit elevated nighttime BP and attenuated BP dipping, including in young adulthood. Social determinants of health contribute to disparities in CVD risk, but the contribution of neighborhood deprivation on nighttime BP is unclear.

Background: Inadequate hydration is associated with cardiovascular and kidney disease morbidity and all-cause mortality. Compared with White individuals, Black individuals exhibit a higher prevalence of inadequate hydration, which may contribute to racial health disparities. However, the underlying reasons for these differences in hydration remain unclear.

Objective: The objective of this study was to examine whether experiences of discrimination have increased during the pandemic, particularly among negatively stigmatized racial/ethnic groups, and whether such experiences have exacerbated feelings of social isolation.

Method: Discrimination and social isolation were assessed before and during the pandemic in a sample of 263 Black and White young adults attending a large, predominantly White 4-year research university in the Southeastern region of the United States (52% Black, 48% White, 53% female, mean age = 19.2).

The influence of childhood contexts on adult blood pressure is an important yet understudied topic. Using a developmental perspective, this study examines the association between neighborhood socioeconomic disadvantage in early childhood (0-5 yrs), middle childhood (6-12 yrs) and adolescence (13-18 yrs) on subsequent blood pressure in young adulthood. Data were from 263 college students (52% Black; M = 19.

The impact of the COVID-19 pandemic on emerging adults is of global concern. We examine changes in depressive symptoms, physical symptoms, and sleep-wake problems from before to during the pandemic among college students, and examine inequalities by gender, socioeconomic status (SES), and race (=263, 52% Black, 48% White, 53% female). As compared to pre-pandemic levels, increases were evident in depressive symptoms, physical symptoms, and sleep problems.

Objectives: Black adults in the United States have shorter sleep durations and poorer sleep efficiency relative to White adults, yet reasons for these disparities are not well explicated. The objective of this study was to examine neighborhood safety in childhood as a mediator of subsequent racial disparities in sleep.

Methods: Data were from Black and White young adults attending a large, predominantly White university in the Southeastern United States (N = 263; 52% Black, 53% female; Mean age = 19.

Understanding the changing health consequences of childhood socioeconomic disadvantage (SED) is highly relevant to policy debates on inequality and national and state goals to improve population health. However, changes in the strength of association between childhood SED and adult health over historic time are largely unexamined in the United States. The present study begins to address this knowledge gap.

Objectives: Studies of discrimination and sleep have largely focused on between-person differences in discrimination as a correlate of sleep outcomes. A common criticism of this research is that standard questionnaire measures of discrimination may be confounded by personality and identity and are subject to recall bias. Partially addressing these limitations, the current study examined within-person, day-to-day fluctuations in perceived discrimination as a predictor of day-to-day fluctuations in sleep.

Associations between attachment security, assessed as a secure base script (SBS), and teachers' social competence ratings were examined in two samples (one from the Midwest region and the other from the Southern region of the United States). Consistent with previous reports, significant associations between domains were obtained in both samples and after combining the two samples, r = .33, p < .

Building on aframework presented by Bretherton and associates, Waters and associates argued that interaction sequences relevant to children's access to and use of asecure base for exploration during infancy/toddlerhood become internalized as script-like representations. For adults, these scripted representations are readily assessed using word-prompt lists d to elicit attachment relevant narratives. However, this method is not appropriate during early childhood.
