Discrimination and sleep disturbance among older Black Americans: A longitudinal analysis of the Health and Retirement Study.

Objectives: Black and older adults have higher risk for sleep problems than their White and younger counterparts. Yet, our understanding of the determinants of sleep problems specifically among older Black adults is severely limited. The aim of this study was to determine whether everyday and major discrimination are longitudinally associated with sleep disturbance in a nationally representative sample of older Black adults.

Chronic stress exposure, social support, and sleep quality among African Americans: findings from the National Survey of American Life-Reinterview.

Objective: The purpose of this study was to determine whether social support from extended family and church members moderate the association between chronic stress exposure and sleep quality in a nationally representative sample of African American adults.

Design: Data from African American respondents aged 18 and older were drawn from the National Survey of American Life-Reinterview. The analytic sample for this study included 1,372 African American adults who attended religious services at least a few times a year, as the church-based relationship measures were only assessed for these individuals.

Circadian Gating of Thyroid Hormone Action in Hepatocytes.

Thyroid hormones, thyroxin (T) and the biologically active triiodothyronine (T), play important roles in liver metabolic regulation, including fatty acid biosynthesis, beta-oxidation, and cholesterol homeostasis. These functions position TH signaling as a potential target for the treatment of metabolic dysfunction-associated steatotic liver disease (MASLD). Elevated T levels in the circulation are associated with increased hepatic lipid turnover, which is also under the control of the circadian clock system.

Ethno-racial differences in anxiety and depression impairment among emerging adults in higher education.

Background: Despite having higher exposure to stressors, many ethno-racial groups report similar or lower prevalence of clinical depression and anxiety compared to their White counterparts, despite experiencing greater psychosocial risk factors for poor mental health outcomes, thus presenting an epidemiological paradox. Ethno-racial differences in impairment, a diagnostic criterion, may in part explain this paradox.

Methods: We analyzed data from the Healthy Minds Study (2020-2021) and using survey-weighted linear mixed effects models, we tested whether there were ethno-racial differences in impairment across multiple ethno-racial groups at various levels of severity for anxiety and depression.
