The Relationship between Body Mass Index and Level of Response to Alcohol Across the Spectrum of Alcohol Use: Total Body Water and Beyond.
J Stud Alcohol Drugs
January 2025
Human Psychopharmacology Laboratory, Division of Intramural Clinical and Biological Research (DICBR), National Institute on Alcohol Abuse and Alcoholism (NIAAA), Bethesda, Maryland, USA.
Background: A low level of response (LR) to alcohol is a known risk factor for alcohol use disorder (AUD). Although higher total body water (TBW) is associated with lower blood alcohol concentrations and reduced responses following alcohol consumption, the relationship between morphometric measures such as body mass index (BMI) and LR is less clear. This study aimed to examine the relationship between BMI and LR to alcohol, and the contribution of TBW to this relationship.

Methods: We analyzed data from three annual assessments of older people living with HIV (PLWH) and age- and sex-similar people not living with HIV (PnLWH). We fitted linear generalized estimating equations (GEE) regression models to estimate the correlates of PA, including demographics, frailty, QoL, HIV, and other comorbidities.
Sex-specific associations between self-reported sleep characteristics and 10-year cardiovascular disease risk in men and women of African descent living in a low socioeconomic status environment.
Sleep Epidemiol
December 2024
Health through Physical Activity, Lifestyle and Sport Research Centre and Division of Physiological Sciences, Department of Human Biology, Faculty of Health Sciences, University of Cape Town, Cape Town, South Africa.
Background: Risk factors for cardiovascular disease (CVD) and sleep health are well-known to be sex- and race-specific. To build on the established relationship between sleep duration and CVD risk, this cross-sectional study aimed to describe sex-specific associations between CVD risk and other sleep characteristics (sleep quality, sleep timing and sleep onset latency) in low-income adults of African descent.
Methods: Self-reported sleep (Pittsburgh Sleep Quality Index [PSQI], Epworth Sleepiness Scale [ESS], Insomnia Severity Index [ISI]), demographic and lifestyle data were collected in 412 adults (56 % women, 35.
An intersectional examination of the relationship between racial/ethnic discrimination and psychotic-like experiences: the role of other psychiatric symptoms.
Eur Psychiatry
January 2025
Department of Psychology and Neuroscience, Temple University, Philadelphia, PA, USA.
Background: Racial and ethnic experiences of discrimination (EODs) are associated with numerous psychiatric symptoms, including outcomes along the psychosis spectrum; however, less is known about mechanisms by which EODs confer risk for psychotic-like experiences (PLEs; common subthreshold psychotic symptoms). Furthermore, work on gendered racism asserts that the intersection of race and gender impacts the nature of EODs experienced and, in turn, may impact the relationship between EODs and PLEs.
Aims: To utilize an intersectional lens (race and gender) to examine whether psychological correlates of EODs (post-traumatic stress, anxiety, depression, and dissociation) mediate the EOD-PLE relationship.
Genetic variants in COMT and ESR1 genes shape treatment response to raloxifene in schizophrenia-spectrum disorders.
Psychoneuroendocrinology
January 2025
Department of Psychiatry, University Medical Center Groningen, Groningen, the Netherlands.
Background/objective: Raloxifene, a selective estrogen receptor modulator (SERM), may improve symptoms and cognition in schizophrenia spectrum disorders (SSD). Studies have shown inconsistent efficacy, especially in men with SSD. We assessed whether single nucleotide polymorphisms (SNPs) on genes involved in the pharmacodynamics (ESR1 and COMT) and pharmacokinetics (UGT1A8) of raloxifene can explain the heterogeneous treatment response to raloxifene augmentation in patients with SSD.
