Adolescent health and the intersectionality of ethnicity/race, sex, and sexual orientation: A national probability sample from the Adolescent Brain Cognitive Development study.

Although children with marginalized sociodemographic characteristics are exposed to increased health risk and disparities, there is a paucity of population-based research on health status of children occupying multiple social marginalities. The present study investigated implications of children's intersectional sociodemographic characteristics on health risk indicators. In this longitudinal cohort study, we used longitudinal data from the ongoing Adolescent Brain Cognitive Development study.

Race, Ethnicity, and Sleep in US Children.

Importance: Although racial and ethnic disparities are well documented in children's mean levels of sleep, particularly duration, evidence is mixed for sleep variability, an important sleep dimension of growing interest. Most research has also focused on comparisons of Black and White children, with limited attention to sleep variability disparities among other racially and ethnically minoritized groups such as Asian, Latinx, and multiracial children.

Objective: To investigate racial and ethnic disparities in children's mean levels of sleep and variability of sleep across multiple dimensions and diverse racial and ethnic groups using actigraphy data.

Comparing Accuracy of Parallel Analysis and Fit Statistics for Estimating the Number of Factors With Ordered Categorical Data in Exploratory Factor Analysis.

Determining the number of factors in exploratory factor analysis (EFA) is crucial because it affects the rest of the analysis and the conclusions of the study. Researchers have developed various methods for deciding the number of factors to retain in EFA, but this remains one of the most difficult decisions in the EFA. The purpose of this study is to compare the parallel analysis with the performance of fit indices that researchers have started using as another strategy for determining the optimal number of factors in EFA.

Perceived Stress and Health Outcomes Among Latinx and Non-Latinx White Adult People With HIV in East Harlem, New York: A Cross-Sectional Study.

Stress and HIV disproportionately affect Latinx adults in the United States, contributing to numerous health inequities. Among people living with HIV (PLWH), increased stress is associated with decreased medication adherence, effectiveness, and higher rates of immunosuppression and comorbidities. Our study ( N = 126) examined the relationship between perceived stress and HIV-related health among Latinx ( n = 83) and non-Latinx White ( n = 43) PLWH.

Corresponding Changes in Sleep and Discrimination: A Three-year Longitudinal Study Among Ethnically/Racially Diverse Adolescents.

Although research has established the immediate, detrimental impact of discrimination on sleep, how changes in experiences of discrimination may be related to changes in sleep duration over multiple years is less clear. This three-year longitudinal study investigated: (1) intercept-only and linear trajectories of sleep and everyday discrimination across three years of high school; (2) ethnic/racial differences in these trajectories; and (3) the associations between changes in sleep and changes in everyday discrimination. The sample consisted of ethnically/racially minoritized adolescents from five northeast U.

Disparate trajectories of cognitive aging among American Indian and Alaskan Native people with and without HIV.

Objective: This study describes trajectories of cognitive aging among American Indian/Alaskan Native (AI/AN) adults with and without HIV and the role of immunosenescence longitudinally.

Method: We characterized trajectories of cognitive aging in a sample of 333 AI/AN and 309 non-Hispanic White (NHW) adults who were followed longitudinally for up to 20 years by the HIV Neurobehavioral Research Program (HNRP) across six U.S.

Postmortem tissue biomarkers of menopausal transition.

The menopausal transition (MT) is associated with an increased risk for many disorders including neurological and mental disorders. Brain imaging studies in living humans show changes in brain metabolism and structure that may contribute to the MT-associated brain disease risk. Although deficits in ovarian hormones have been implicated, cellular and molecular studies of the brain undergoing MT are currently lacking, mostly due to a difficulty in studying MT in postmortem human brain.

Longitudinal Associations Between Friendship Ethnic/Racial Composition and Ethnic/Racial Identity: The Role of School Ethnic/Racial Diversity.

Schools and friendships represent important but distinct contexts for adolescent identity development. However, research has yet to explore the long-term interplay between these factors on ethnic/racial identity (ERI). This study included a sample of 640 adolescents from 9 public high schools in a diverse United States metropolis (M = 14.

Racial-Ethnic Discrimination and Early Adolescents' Behavioral Problems: The Protective Role of Parental Warmth.

Objective: The purpose of the study was to investigate the association between discrimination by multiple sources (ie, teachers, students, and other adults) and early adolescents' behavioral problems (ie, internalizing, externalizing, and attention problems), also considering the protective role of parental warmth in the association.

Method: Cross-sectional analyses were conducted with 3,245 early adolescents of color obtained from the Adolescent Brain Cognitive Development Study (ABCD Study) at year 1 follow-up (Y1), a large and diverse sample of children (mean age = 9.48 years) in the United States.

Multiple Discrimination and Substance Use Intention in Late Childhood: Findings From the Adolescent Brain Cognitive Development (ABCD) Study.

Purpose: The study aimed to investigate longitudinal, bidirectional associations between discrimination due to multiple reasons (race/ethnicity, sexual orientation, weight; termed multiple discrimination) and substance use (SU) intention in late childhood. These associations were compared across youth with no, single, and multiple (i.e.

Novel Assessment of the Impact of Irritability on Physiological and Psychological Frustration Responses in Adolescents.

Objective: Irritability, typically defined as a proneness to anger, particularly in response to frustration, falls at the intersection of emotion and disruptive behavior. Despite well-defined translational models, there are few convergent findings regarding the pathophysiology of irritability. Most studies utilize computer-based tasks to examine neural responses to frustration, with little work examining stress-related responding to frustration in social contexts.

Ethnic/Racial Identity, Adolescent Sleep, and Somatic Health: Discrimination and Stress Responses as Mediating Mechanisms.

Purpose: This study sought to examine whether the daily associations between ethnic/racial discrimination and stress responses served as mediators linking ethnic/racial identity (ERI), adolescent sleep health, and somatic symptoms.

Methods: Data were drawn from 279 adolescents of color (69% female; 24% African Americans; 31% Asian Americans; 41% Latinx; and 4% unknown ethnicity/race; M = 14.31 years, SD = 0.

The Community Engaged Digital Alzheimer's Research (CEDAR) Study: A Digital Intervention to Increase Research Participation of Black American Participants in the Brain Health Registry.

Background: Although Black/African American older adults bear significant inequities in prevalence, incidence, and outcomes of Alzheimer's disease and related dementias, they are profoundly under-included in Alzheimer's Disease research. Community-Engaged Research (e.g.

Early-life stress and ovarian hormones alter transcriptional regulation in the nucleus accumbens resulting in sex-specific responses to cocaine.

Early-life stress and ovarian hormones contribute to increased female vulnerability to cocaine addiction. Here, we reveal molecular substrates in the reward area, the nucleus accumbens, through which these female-specific factors affect immediate and conditioning responses to cocaine. We find shared involvement of X chromosome inactivation-related and estrogen signaling-related gene regulation in enhanced conditioning responses following early-life stress and during the low-estrogenic state in females.

Understanding Gender-Based Violence Service Delivery in CDC-Supported Health Facilities: 15 Sub-Saharan African Countries, 2017-2021.

Gender-based violence (GBV) is a complex issue deeply rooted in social structures, making its eradication challenging. GBV increases the risk of HIV transmission and is a barrier to HIV testing, care, and treatment. Quality clinical services for GBV, which includes the provision of HIV postexposure prophylaxis (PEP), vary, and service delivery data are lacking.

Understanding Online Registry Facilitators and Barriers Experienced by Black Brain Health Registry Participants: The Community Engaged Digital Alzheimer's Research (CEDAR) Study.

Background: Failure of Alzheimer's disease and related diseases (ADRD) research studies to include and engage Black participants is a major issue, which limits the impact and generalizability of research findings. Little is known about participation of Black adults in online ADRD-related research registries.

Objectives: As part of the Community Engaged Digital Alzheimer's Research (CEDAR) Study, this study aims to increase our understanding of facilitators and barriers of Black adults to participating in ADRD-related online registries, as well as to understand their preferences for communication channels.

Effect size measure for mediation analysis with a multicategorical predictor.

Many currently available effect size measures for mediation have limitations when the predictor is nominal with three or more categories. The mediation effect size measure υ was adopted for this situation. A simulation study was conducted to investigate the performance of its estimators.

The neurocognitive implications of depression and socioeconomic status in people with HIV.

Objective: This cross-sectional study investigates the independent and interactive effects of depression and socioeconomic status (SES) on neurocognition in a diverse sample of people with HIV (PWH).

Method: The sample of 119 PWH (71% Latinx, 27% female) completed comprehensive neurocognitive and psychosocial evaluations and were separated into two groups: those with a history of depression diagnosis ( = 47) and those without ( = 72).

Results: The results of regression analyses indicated that lifetime depression was not associated with lower SES nor with worse neurocognitive performance on any neurocognitive outcome.

Why the estrous cycle matters for neuroscience.

Background: Ovarian hormone fluctuations over the rodent estrous cycle and the human menstrual cycle are known to significantly impact brain physiology and disease risk, yet this variable is largely ignored in preclinical neuroscience research, clinical studies, and psychiatric practice.

Methods: To assess the importance of the estrous cycle information for the analysis of sex differences in neuroscience research, we re-analyzed our previously published data with or without the estrous cycle information, giving a side-by-side comparison of the analyses of behavior, brain structure, gene expression, and 3D genome organization in female and male mice. We also examined and compared the variance of female and male groups across all neurobehavioral measures.

Measuring a Patient's understanding of their prognosis: An exploratory analysis.

Objective: In patients with cancer across the illness trajectory, treatment decisions are often influenced by one's perception of their prognosis (i.e., curability of disease, life expectancy, quality of life).

An ultra-brief screening scale for pediatric obsessive-compulsive disorder: The OCI-CV-5.

Background: Obsessive-compulsive disorder (OCD) is an often disabling and chronic condition that is normally assessed using diagnostic interviews or lengthy self-report questionnaires. This makes routine screening in general health settings impractical, and as a result OCD is often under-(or mis-)recognized. The present study reports on the development of an ultra-brief version of the Obsessive-Compulsive Inventory-Child Version (OCI-CV) which may be administered routinely as a screener for pediatric OCD.

Linking ethnic/racial discrimination to adolescent mental health: Sleep disturbances as an explanatory pathway.

Ethnic/racial discrimination is associated with negative psychosocial outcomes, and this study considered sleep disturbance as a mediating pathway. Employing a combination of daily diary and biannual surveys, multilevel structural equation models estimated the indirect effects of sleep/wake concerns on negative, anxious, and positive mood, rumination, and somatic symptoms. In a sample of 350 urban Asian (74% Chinese, 8% Korean, 4% Indian, 1% Filipinx, 1% Vietnamese, and 12% other), Black, and Latinx (25% Dominican, 24% South American, 22% Mexican, 15% Puerto Rican, 5% Central American, and 9% other) youth (M = 14.

The OCI-CV-R: A Revision of the Obsessive-Compulsive Inventory - Child Version.

Background: The Obsessive-Compulsive Inventory-Children's Version (OCI-CV) was developed to assess obsessive-compulsive symptoms in youth. Recent changes in the Diagnostic and Statistical Manual (DSM-5) exclude hoarding from inclusion in the diagnosis of obsessive-compulsive disorder (OCD). Accordingly, the present study examined the reliability, validity, factorial structure, and diagnostic sensitivity of a revised version of the scale - the OCI-CV-R- that excludes items assessing hoarding.
