Article Abstract

Background: Traumatic childhood experiences (TCEs) are associated with poor adulthood sleep, but racial/ethnic disparities have not been well-studied. We investigated the TCE-adulthood sleep relationship among non-Hispanic (NH)-White, NH-Black, and Hispanic/Latina women.

Method: Women enrolled in the Sister Study from 2003 to 2009 reported the following TCEs in a follow-up interview (2008-2012): natural disasters; major accidents; household dysfunction; and sexual, physical, and psychological/emotional abuse. Sleep characteristics included short sleep duration (< 7 h vs. 7-9 h), long sleep onset latency (SOL) (> 30 vs. ≤ 30 min), frequent night awakenings (≥ 3 times/night ≥ 3 times/week [yes vs. no]), and frequent napping (≥ 3 vs. < 3 times/week). Using log-binomial regression to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) for sleep characteristics among women with vs. without TCEs, we investigated racial/ethnic-specific associations and race/ethnicity as a moderator.

Results: Among 40,082 participants (mean age = 55 ± 8.8 years), 55% reported ≥ 1 TCE (NH-White, 54%; NH-Black, 62%; Hispanic/Latina, 57%). NH-White, NH-Black, and Hispanic/Latina women reporting any TCE had a higher prevalence of short sleep compared with their within-race/ethnicity counterparts without TCEs. Associations were strongest among NH-Whites. Compared to NH-Whites with no TCEs, racial/ethnic minorities who reported any TCEs had a higher prevalence of short sleep (PR = 2.13 [95% CI 2.02-2.24], PR = 1.47 [1.35-1.60]) and long SOL. When comparing racial/ethnic minorities with TCEs to NH-Whites with TCEs, PRs for short sleep (PR = 1.98 [1.88-2.08] and PR = 1.36 [1.25-1.48]) and long SOL were weaker.

Conclusion: TCEs were positively associated with poor sleep characteristics among women, and TCEs appear to contribute to short sleep duration and long SOL disparities.

Objective: One of the most frequent neuropsychiatric complications after a stroke is poststroke depression (PSD). However, it is unclear whether disparities exist in PSD diagnosis. The authors examined a 10-year trend in PSD by socioeconomic and clinical characteristics.

Objective: To examine the impact of patient-provider racial/ethnic concordance on adherence to a prescribed medication regimen in marginalized populations with a focus on health issues related to hypertension, heart condition/disease, elevated cholesterol, and diabetes.

Study Setting And Design: Applying the Andersen-Newman Behavioral Model of Health Service Use, we estimate multivariate linear models to analyze the number of prescriptions filled by patients within a calendar year using publicly available data from the Medical Expenditure Panel Survey (MEPS), a set of large-scale surveys of families and individuals, their medical providers, and employers across the United States.

Data Sources And Analytic Sample: Data from MEPS on patient race/ethnicity and provider race/ethnicity were collected from survey years 2007 to 2017 as well as data to control for demographic, socioeconomic, and health factors.

Racial and ethnic disparities in healthy aging represent an emerging public health crisis that will only grow worse as our population grows older. Healthy lifestyle behaviors are proposed as a key strategy to promote healthy aging. However, the potential of lifestyle interventions to address aging health disparities is uncertain.

The Oncotype DX test is standardly used for patients with early-stage, hormone-receptor-positive, HER2-negative breast cancers to determine the benefit from chemotherapy and the likelihood of distant recurrence. The relationship between Oncotype DX recurrence scores and race/ethnicity is still being studied. This retrospective study aims to evaluate the relationship between Oncotype DX recurrence scores, race/ethnicity, and clinicopathological factors and to support the applicability of the Oncotype DX test for a diverse breast cancer population of Hawaii.

Introduction: Type 2 diabetes mellitus (T2DM) microvascular complications are a major public health issue that disproportionately affects racial/ethnic minorities in the US. We aimed to address the limited understanding of racial/ethnic disparities in the longitudinal natural history of microvascular complications over eight years among older adults with T2DM in the US and Canada.

Methods: From 10,251 participants in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) (2003-2009) trial, we derived 6323 participants.
