Older people with HIV (PWH) experience heightened risk for the acquisition of cumulative, multisystem decline, i.e., frailty syndrome. Frailty relates to poorer sleep quality in the general older adult population; however, this association has yet to be explored among PWH. A cross-sectional analysis of 285 PWH ≥50 years old (mean age 60.5 ± 7.0) examined the relationship between frailty (Fried frailty phenotype) and self-reported sleep quality (Pittsburgh Sleep Quality Index; PSQI). Three separa...

Most previous studies investigating sleep’s association with health outcomes have relied on averaged sleep quality and laboratory-based health measures. This study examines the dynamic within-person relationships between subjective (Ecological Momentary Assessment) and objective sleep (actigraphy) on next-day cognition (subjective and objective), mood, and engagement in daily activities using linear mixed-effects regression modeling. Participants included 94 individuals (59 people with HIV, 35 H...

OBJECTIVE Recent cannabis exposure has been associated with lower rates of neurocognitive impairment in people with HIV (PWH). Cannabis's anti-inflammatory properties may underlie this relationship by reducing chronic neuroinflammation in PWH. This study examined relations between cannabis use and inflammatory biomarkers in cerebrospinal fluid (CSF) and plasma, and cognitive correlates of these biomarkers within a community-based sample of PWH. METHODS 263 individuals were categorized into four ...

Background Even in the era of suppressive antiretroviral therapy, people with HIV (PWH) suffer greater exposure to inflammation than their uninfected peers. Although poor social support and social isolation have been linked to systemic inflammation in the general population, it is not known whether this is true also among PWH. Methods People with and without HIV infection were enrolled in a community-based, single-center study. Primary predictors were the Medical Outcomes Study Social Support Su...

This study evaluated whether a history of lifetime methamphetamine (MA) use disorder increases risk for poor sleep quality in people with or without HIV infection (HIV+/HIV-). Participants (n = 313) were stratified into four groups based on HIV status and lifetime MA use disorder diagnosis [HIV+/MA+ (n = 84); HIV+/MA- (n = 141); HIV-/MA+ (n = 16); and HIV-/MA- (n = 72)] and compared on global sleep outcomes using the Pittsburgh Sleep Quality Index (PSQI). Significant differences on global sleep ...

BACKGROUND: Frailty disproportionally affects people with HIV (PWH) and increased frailty in this already vulnerable population is associated with worse neurocognitive functioning. Whether frailty interacts with current and modifiable markers of HIV disease severity to synergistically increase risk for HIV-Associated Neurocognitive Disorders (HAND), however, is unknown and important for informing the clinical care of aging PWH. SETTING: UC San Diego's HIV Neurobehavioral Research Program METHODS...

Both HIV disease and frailty syndrome are risk factors for neurocognitive impairment. Longitudinal research among individuals of the general population suggests that frailty predicts future cognitive decline; however, there is limited evidence for these longitudinal relationships among people living with HIV (PLWH). The current study evaluated and compared rates of cognitive decline over 2 years among HIV serostatus and frailty status groups. Participants included 50 PLWH and 60 HIV-uninfected (...

ABSTRACTThis study examined the association between self-reported fatigue and neuropsychological performance in 167 middle-aged and older (age range: 50–91 years) adults without dementia. Participants completed the Fatigue Symptom Inventory, a comprehensive neuropsychological evaluation, and frailty assessment. Higher levels of fatigue were significantly associated with poorer attention/information processing, executive functioning, and psychomotor speed, even after controlling for depression, s...

Many factors can influence perceptions of successful aging (SA), including social isolation and poor physical health. We hypothesized that social support attenuates the negative effect of plasma D-dimer, a correlate of HIV and aging, on SA. Participants included 230 adults (134 people with HIV; PWH, 96 HIV−), ages 36–65, segregated into age cohorts with up to 5 yearly visits. Multilevel modeling examined longitudinal within-person associations between D-dimer, social support, and SA. Social supp...
