"As I Grew Older, My Life Got Better": Conceptions of Successful Aging among Older Women Living with or at Risk of HIV

Successful aging (SA) is an important target for HIV care. However, we have insufficient understanding of how older women living with HIV (OWLH) in the US define SA. We explored conceptions of SA by OWLH and older women at risk of HIV and examined whether SA conceptions differed by (1) HIV serostatus, and (2) participation in the Women's Interagency HIV Study (WIHS). These analyses were part of a larger mixed-methods study with a sequential design. Participants were recruited at two clinical WIHS sites. We enrolled both WIHS participants and non-WIHS clinic patients. Our sample was 84% Black and included 29 OWLH and 15 older women at risk of HIV. We conducted 21 semi-structured interviews and four focus groups. The dataset was analyzed using descriptive, comparative, and relational analysis. We found four interlinked themes: life course perspective, accepting and celebrating aging, taking care of yourself, and looking good. The life course perspective was a core theme: participants assessed their aging in comparison to their earlier life hardships. These themes were similarly present among OWLH and older women at risk of HIV, although OWLH emphasized taking care of HIV. SA conceptualizations by OWLH did not differ whether or not they participated in the WIHS. Women living with or at risk of HIV may experience severe hardships throughout their lives. Overcoming these hardships may be linked to SA. Assessing the needs and connecting women to resources and programs are critical for SA promotion.

Project EPIC (Empowering People to Independence in COPD): Study protocol for a hybrid effectiveness-implementation pilot randomized controlled trial of telephonic, geriatrics-palliative care nurse-coaching in older adults with COPD and their family caregivers

BACKGROUND

EPIC (Empowering People to Independence in COPD) is a geriatric-palliative care telephonic, nurse coach intervention informed by Baltes' Theory of Successful Aging and adapted from the ENABLE (Educate, Nurture, Advise, Before Life Ends) intervention. EPIC, focused on improving independence, mobility, well-being, and COPD symptoms, has undergone formative and summative evaluation for adults with COPD.

METHODS

The primary study aim is to assess the refined EPIC intervention's feasibility and acceptability via a pilot hybrid effectiveness-implementation randomized control trial in community-dwelling older adults with moderate to severe COPD and their family caregivers. The secondary aim is to explore the impact of EPIC on patient and caregiver outcomes. Older adults with COPD and their family caregivers (target N = 60 dyads) will be randomized to EPIC (intervention) or usual COPD care (control). EPIC includes six patient and four family caregiver weekly, telephone-based nurse coach sessions using a manualized curriculum (Charting Your Course), plus three monthly follow-up calls. Feasibility will be measured as completion of EPIC intervention and trial components (e.g., recruitment, retention, data collection). Acceptability will be evaluated using satisfaction surveys and post-study feedback interviews. A blinded data collector will assess exploratory outcomes (e.g., Life-Space mobility, quality of life, caregiver burden, emotional symptoms, loneliness, cognitive impairment, functional status, healthcare utilization) at baseline, 12, and 24 weeks.

DISCUSSION

This intervention fills a gap in addressing the geriatrics and palliative care needs and equity for adults with COPD and their family caregivers.

Associations Between Estimates of Arterial Stiffness and Cognitive Functioning in Adults With HIV

BACKGROUND

Vascular aging, a precursor of arterial stiffness, is associated with neurocognitive impairment (NCI) and cardiovascular disease. Although HIV is associated with rapid vascular aging, it is unknown whether arterial stiffness mediates changes in cognitive function. We explored whether estimated markers of vascular aging were associated with NCI indices in HIV-positive individuals.

METHODS

This study was a secondary analysis of an observational study. Neurocognitive functioning was assessed using a battery of 7 domains (verbal fluency, executive functioning, speed of information processing, attention/working memory, memory [learning and delayed recall], and motor skills). Vascular aging was assessed using estimated markers of arterial stiffness (ie, estimated pulse wave velocity, pulse pressure, and vascular overload index). A multivariable regression adjusted for demographics, cardiovascular disease risk factors, and HIV clinical variables was used to examine the association between vascular aging and NCI outcomes.

RESULTS

Among 165 people with HIV, the mean age was 51.5 ± 6.9 years (62% men and 83% African American/Black or Other). In fully adjusted models, an increase in estimated pulse wave velocity and pulse pressure was associated with lower T scores in learning (-2.95 [-5.13, -0.77]) and working memory (-2.37 [-4.36, -0.37]), respectively. An increase in vascular overload index was associated with lower T scores in working memory (-2.33 [-4.37, -0.29]) and learning (-1.85 [-3.49, -0.21]).

CONCLUSIONS

Estimated markers of arterial stiffness were weakly associated with neurocognitive functioning, suggesting that vascular aging may have a role in cognitive decline among people with HIV.

Does Olfactory Training Improve Brain Function and Cognition? A Systematic Review

Olfactory training (OT), or smell training,consists of repeated exposure to odorants over time with the intended neuroplastic effect of improving or remediating olfactory functioning. Declines in olfaction parallel declines in cognition in various pathological conditions and aging. Research suggests a dynamic neural connection exists between olfaction and cognition. Thus, if OT can improve olfaction, could OT also improve cognition and support brain function? To answer this question, we conducted a systematic review of the literature to determine whether there is evidence that OT translates to improved cognition or altered brain morphology and connectivity that supports cognition. Across three databases (MEDLINE, Scopus, & Embase), 18 articles were identified in this systematic review. Overall, the reviewed studies provided emerging evidence that OT is associated with improved global cognition, and in particular, verbal fluency and verbal learning/memory. OT is also associated with increases in the volume/size of olfactory-related brain regions, including the olfactory bulb and hippocampus, and altered functional connectivity. Interestingly, these positive effects were not limited to patients with smell loss (i.e., hyposmia & anosmia) but normosmic (i.e., normal ability to smell) participants benefitted as well. Implications for practice and research are provided.

Symptomatology and Quality of Life of Older People With HIV and Comorbid Chronic Obstructive Pulmonary Diseases From an HIV Clinic in Birmingham, Alabama

ABSTRACT

Psychological symptomatology and quality of life (QoL) have been studied in older people with HIV (PWH) and those with chronic obstructive pulmonary disease (COPD), respectively, but there is a dearth of studies in older PWH with COPD. Our study compared depressive symptoms, anxiety, and QoL between older PWH with and without COPD using data from an HIV clinic in Birmingham, Alabama, from January 2018 to February 2020. Data on depressive symptoms (Patient Health Questionnaire-9), anxiety (Patient Health Questionnaire-5 Anxiety), and QoL (EuroQoL-5 Dimension) were analyzed. Among 690 PWH aged 50 years or older, 102 individuals (14.8%) had COPD. Significant differences were found between the two groups in depressive symptoms and components of QoL (e.g., mobility, self-care, usual activities, and pain/discomfort), but not in anxiety and general health. Experiencing COPD may worsen depressive symptomatology and QoL in older PWH, highlighting the need for tailored health care and research for this population.

A 2-year longitudinal randomized controlled trial examining the transfer of speed of processing training to secondary cognitive domains in middle-aged and older adults with HIV-associated neurocognitive disorder: Results of the think fast study

OBJECTIVE

As people with HIV (PWH) age, they are at-risk of developing cognitive impairments compared to their seronegative counterparts. Although speed of processing (SOP) training may help improve this cognitive ability, less work has examined transfer to other cognitive domains. This study examined the effect of SOP training has on secondary cognitive domains in PWH aged 40+ years.

METHOD

In this 3-group 2-year longitudinal study, 216 PWH with HIV-associated neurocognitive disorder (HAND) or borderline HAND were randomized to either: (1) 10 h of SOP training (n = 70); (2) 20 h of SOP training (n = 73); or (3) 10 h of an active control training (n = 73). Participants completed a comprehensive cognitive battery at baseline, immediately after training, and at 1 and 2 years. This battery yielded global and domain specific T-scores as well as a cognitive impairment variable. Generalized linear mixed-effect models were fitted to estimate between-group mean differences at the follow-up time-points adjusted for baseline.

RESULTS

No clinically or statistically significant improvements in any of the cognitive outcomes were observed. A sensitivity analysis was conducted; conclusions replicated those of the main analysis, with two exceptions: Global Function T and Psychomotor Speed T showed relevant training improvements among the intervention groups over the control group at the immediate post time point.

CONCLUSIONS

Although SOP training has been shown to improve cognitive abilities that correspond to driving and mobility, such training has limited therapeutic utility in improving cognition in other domains in PWH with HAND.

Cognitive prescriptions for reducing dementia risk factors among Black/African Americans: feasibility, acceptability, and preliminary efficacy

OBJECTIVES

Black/African Americans (B/AAs) have double the risk of Alzheimer's disease and related dementia than Whites, which is largely driven by health behaviors. This study examined the feasibility, acceptability, and preliminary efficacy of a pilot randomized clinical trial of an individualized multidomain health behavior intervention among middle-aged and older B/AAs (dubbed Cognitive Prescriptions [CogRx]).

DESIGN

Thirty-nine community-dwelling B/AA participants aged 45-65 without significant cognitive impairment were randomized to one of three groups: CogRx, Psychoeducation, or no-contact control. The Psychoeducation and CogRx groups received material on dementia prevalence, prognosis, and risk factors, while the CogRx group additionally received information on their risk factor profile across the five CogRx domains (physical, cognitive, and social activity, diet, sleep). This information was used for developing tailored 3-month goals in their suboptimal areas.

RESULTS

The CogRx program had high retention (all 13 CogRx participants completed the 3-month program and 97% of the full sample completed at least 1 follow-up) and was well-received as exhibited by qualitative and quantitative feedback. Themes identified in the positive feedback provided by participants on the program included: increased knowledge, goal-setting, personalization, and motivation. The COVID-19 pandemic was a consistent theme that emerged regarding barriers of adherence to the program. All three groups improved on dementia knowledge, with the largest effects observed in CogRx and Psychoeducation groups. Increases in cognitive, physical, and overall leisure activities favored the CogRx group, whereas improvements in sleep outcomes favored Psychoeducation and CogRx groups as compared to the control group.

CONCLUSION

The CogRx program demonstrated feasibility, acceptability, and preliminary efficacy in increasing dementia knowledge and targeted health behaviors. Further refinement and testing of the implementation and effectiveness of similar person-centered dementia prevention approaches are needed on a larger scale in diverse populations. Such findings may have implications for clinical and public health recommendations.

The Association Between Intrapersonal Resilience Resources and Quality of Life Among Older Persons Living With HIV: A Systematic Review

ABSTRACT

Despite positive improvements in health care, older persons living with HIV (PWH) still face psychosocial challenges and medical issues that affect their overall quality of life (QoL). Intrapersonal resilience resources may serve as a protective factor allowing PWH to better cope with adversity, thereby improving their well-being. In our systematic review, we examined intrapersonal resilience resources and their association with QoL outcomes among middle-aged and older PWH (≥40 years). Four databases (CINAHL, PubMed, PsycINFO, and Embase) were searched, and 1,400 articles were yielded. Following screening and full-text review, 19 studies met full criteria and were included. Based on our findings from these studies, trait resilience, spirituality, and self-efficacy were the most common resilience resources investigated. Resilience resources were positively associated with QoL outcomes and mediated the association between various psychosocial factors (e.g., stigma) and QoL. Future studies should explore resilience resources and QoL over time among diverse populations of PWH.

Cognitive intra-individual variability in breast cancer survivors: A systematic review

Subjective and objective cognitive impairments in Breast Cancer Survivors (BCS) often do not correlate. One important contribution to the reported disparities may be the reliance on mean-based cognitive performance. Cognitive intra-individual variability (IIV) may provide important insights into these reported disparities. Cognitive IIV refers to the fluctuation in performance for an individual on either one cognitive task across a trial or dispersed across tasks within a neuropsychological test battery. The purpose of this systematic review was to search for and examine the literature on cognitive IIV in BCS. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach was used to search for all articles related to cognitive IIV in BCS. MEDLINE (via PubMed), Embase, and Scopus databases were searched using detailed search terms and strategies. Initially, 164 articles were retrieved but only 4 articles met the criteria for this systematic review. BCS differed from healthy controls in similar ways across the four studies, generally demonstrating similar performance but showing increased cognitive IIV for the more difficult tasks. Differences were enhanced later during chemotherapy. The four studies provide support for cognitive IIV as a useful measure to detect the subtle objective cognitive change often reported by BCS but frequently not detected by standard normed-based cognitive testing. Unexpectedly, measures of cognitive IIV were not consistently associated with self-reported measures of cognition.

A - 83 Associations between Subjective and Objective Cognition, Depression, and Quality of Life in Men Living with HIV

OBJECTIVE

In people living with HIV, subjective cognitive dysfunction is widely reported; however, few studies have examined the relationship between subjective cognitive functioning and performance-based measures of cognitive functioning, mood, and quality of life (QoL).

METHODS

Men living with HIV (MLWH) (n = 51, mean age = 54 years, 67% Black) completed measures of subjective cognitive functioning (Cognitive Failures Questionnaire; CFQ), objective cognitive performance (HVLT-R, TMT, UFOV, WRAT-3 Reading), health-related QoL (Medical Outcomes Short-Form; SF-36), mood (CES-D), and overall QoL (Control, Autonomy, Self-Realization, and Pleasure Quality of Life Scale; CASP-19). Pearson and Spearman correlation analyses were conducted to examine significant associations between variables. Alpha was set at 0.01 for all analyses.

RESULTS

The CFQ was not significantly correlated with performance on objective cognitive tests. However, significant associations were found between the CFQ and self-reported depression severity (CES-D; r = 0.655, p < 0.001), quality of life (CASP-19; r = -0.642, p < 0.001), and multiple subscales of the SF-36 (all p's < 0.003). Of note, correlations between the CFQ with SF-36 scales and CASP-19 were no longer significant after controlling for depressive symptoms.

CONCLUSIONS

Consistent with prior work, we found that subjective cognitive functioning may inadequately capture the full range of a person's cognitive functioning status. We extend these findings to a sample of MLWH and further clarify the possible influence that depressive symptoms have on subjective cognitive functioning and self-reported QoL measures. Future studies with larger samples and a more comprehensive neuropsychological battery will be helpful in understanding the full nature of these relationships.

Resilience in the context of dementia family caregiver mental health: A concept analysis

Resilience has been identified as a key concept for dementia family caregiver mental health; however, the concept is not well defined. A concept analysis examining dementia caregiver resilience was conducted using Rodger's Evolutionary Method. The aim of this concept analysis was to describe the historical perspective, attributes, antecedents, and consequences of resilience as it relates to dementia caregiver mental health. Key attributes of dementia caregiver resilience were acceptance, coping strategies, social support, self-appraisal, and spirituality. The results from this concept analysis provide the foundation for the development of resilience-based interventions to support the well-being of dementia family caregivers.

Alcohol Use Disorder as a Risk Factor for Cognitive Impairment

BACKGROUND

Alcohol use disorder (AUD) is a worldwide problem. The AUD can take the form of hazardous drinking, binge drinking, or alcohol dependence. The effects of alcohol on cognition can be diverse and complex.

OBJECTIVE

Our study aimed to assess AUD as a risk factor for cognitive impairment.

METHODS

A literature search was conducted using major electronic databases of PubMed, EMBASE, and Web of Science. Abstracts were screened independently to include data from original research reports. The following keywords were used: alcohol abuse, cognitive impairment, Alzheimer's disease, and dementia. In total, 767 abstracts were retrieved. After removing the duplicates, 76 articles met the criteria for full-text review, of which 41 were included in this report.

RESULTS

People with AUD are seen from different geographical areas and cultures. AUD is associated with an increased risk of cognitive impairments, Alzheimer's disease, and dementia, especially vascular dementia. In addition, AUD interacts with comorbidities increasing the risk of cognitive impairment.

CONCLUSION

AUD is associated with an increased risk of cognitive impairments, which may have more than one underlying mechanism.

Two-year clinical trial examining the effects of speed of processing training on everyday functioning in adults with human immunodeficiency virus-associated neurocognitive disorder (HAND) and borderline HAND in the U.S. Deep South: Findings of the Think Fast Study

Many people living with human immunodeficiency virus (HIV) (PLWH) experience cognitive decline that impairs everyday functioning. Cognitive training approaches, such as speed of processing (SOP) training, may reduce the impact of HIV-Associated Neurocognitive Disorder (HAND) on everyday functioning. In this experimental design study called the Think Fast Study, 216 participants age 40 and older with HAND or borderline HAND were randomized to one of three groups: (1) 10 h of SOP training (n = 70); (2) 20 h of SOP training (n = 73); or (3) 10 h of Internet Navigation Control Training (a contact control group; n = 73). Participants completed several everyday functioning measures at baseline, posttest, and year 1 and year 2 follow ups, which included: (a) Modified Lawton and Brody Activities of Daily Living (ADL) Questionnaire; (b) Timed Instrumental Activities of Daily Living (TIADL) Test; (c) Patient's Assessment of Own Functioning (PAOFI); (d) Medication Adherence Questionnaire (MAQ); and (e) Medication Adherence Visual Analog Scale (VAS). Linear mixed-effect models and generalized estimating equation models were fitted to estimate between group differences at all follow-up time points. At follow-up timepoints, those in the 10-h and 20-h training groups had better scores on medication adherence measures (MAQ and VAS) than those in the control group, with effects (Cohen's d) ranging 0.13-0.41 for MAQ and 0.02-0.43 for VAS. In conclusion, SOP training improved some indicators of everyday functioning, specifically medication adherence; however, the therapeutic effects diminished over time. Implications for practice and research are posited.

Association between personality and cognitive performance in middle-aged and older adults with human immunodeficiency virus (HIV)

BACKGROUND

Nearly half of adults with human immunodeficiency virus (HIV) experience HIV-Associated Neurocognitive Disorder (HAND), characterized by cognitive impairments in two or more cognitive domains, which can interfere with everyday functioning. Many factors are thought to influence such cognitive impairments in adults with HIV; one factor seldom examined is personality.

OBJECTIVE

This study investigated the association between five major dimensions of personality (openness, conscientiousness, extraversion, agreeableness, and neuroticism) and cognitive function in older adults with HIV.

METHODS

In this cross-sectional study, a secondary data analysis was conducted on 261 HIV + participants. Participants completed a norm-based cognitive battery covering seven cognitive domains, which yielded the following indices: global cognitive impairment, and global and domain-specific T-scores. The Big Five Inventory was used to assess personality traits.

RESULTS

Higher openness, conscientiousness, and agreeableness were associated with better performance on individual cognitive domains while agreeableness and openness were also positively associated with global cognitive T-scores (p < .01). Only openness significantly predicted global cognition when adjusting for covariates (p < .01).

DISCUSSION

Openness was associated with better global cognitive function in persons with HIV. This study provides a basis for further investigation of potential mechanisms for the association between personality and cognition in people with HIV in order to ultimately inform intervention strategies.

The Association Between Objectively-Measured Physical Activity and Cognitive Functioning in Middle-Aged and Older People Living with HIV

Middle-aged and older people living with HIV (PWH) are at higher risk for cognitive impairment and engage in lower levels of physical activity (PA) than seronegative counterparts. Research examining the association between objectively-measured PA and cognitive function in this population is scarce. This cross-sectional study examined the association between accelerometry-measured PA and cognitive functioning among 75 PWH (mean age 55.63). Light PA was the PA variable with the most consistent associations with cognition, with more minutes per week of light PA (performed in bouts of ≥ 10 min) being associated with better executive function, working memory/attention, and speed of processing performance, adjusted for age and current CD4 count. Findings suggest that although middle-aged and older PWH engage in more light than moderate-to-vigorous PA, light PA may be beneficial to cognition. Longitudinal studies are needed to understand PA dose-response associations with cognitive trajectories, cognitive domain specificity of PA effects, and underlying neural mechanisms of PA.

Cardiometabolic Diseases and Quality-of-Life Outcomes in Adults With HIV in the Deep South: A Cross-sectional Study

ABSTRACT

The role of cardiometabolic diseases (CMDs) on physical health-related quality of life (P-HRQoL) and quality of sleep was examined among 261 PLWH ≥40 years, recruited from a university-affiliated HIV clinic in the Deep U.S. South. Using a cross-sectional study design, participants completed the Medical Outcomes Study HIV Health Survey (MOS-HIV; P-HRQoL) and Pittsburgh Sleep Quality Index. The overall prevalence of self-reporting ≥1 CMD was 64.4%. P-HRQoL scores were lower in PLWH with ≥1 CMD compared with those with no CMDs (45.53 ± 11.54 vs. 49.67 ± 10.77, p <.01). Poor sleep quality was higher among participants with ≥1 CMD compared with those with no CMDs (9.28 ± 4.42 vs. 7.26 ± 4.17, p <.01). Each additional CMD resulted in a 1.83-point decrease in P-HRQoL and 0.74-point increase in poor sleep quality scores. Interventions that focus on targeting these quality-of-life domains in PLWH with CMDs are needed.

Tools for Screening and Measuring Anxiety Among Women Living with HIV of Reproductive Age: A Scoping Review

Emerging evidence suggests that women living with HIV (WLWH) may experience higher rates of anxiety than men living with HIV and women living without HIV. To date, relatively little knowledge exists on valid anxiety screening and diagnostic tools and how they are used among WLWH, specifically WLWH of reproductive age. Thus, the purpose of this scoping review was to describe what is known in the published literature about anxiety among WLWH and the tools used to measure and screen for anxiety in clinical and research contexts. The Arksey and O'Malley methodological framework was used to guide a scoping review of published articles in PsycINFO, Scopus, Sociological Abstracts, and PubMed databases. Twenty-one measures of anxiety were used across the 52 articles identified in the search. Most measures used were self-report. Inconsistencies in standardized screening tools and cutoff scores were observed across studies. Further, measures to assess anxiety varied among studies focused on WLWH. Based on the results from this review, there is a need for consistent, valid measures of anxiety to advance research and clinical practice to support the well-being of WLWH.

Preventing Neurocognitive Decline in Adults Aging with HIV: Implications for Practice and Research

Mild to moderate forms of neurocognitive impairment persist among people living with HIV (PLWH), despite being virally suppressed on antiretroviral therapy. PLWH are disproportionally impacted by physiological and psychosocial comorbidities compared to those without HIV. As adults live longer with HIV, the neurocognitive burden of physiological and psychosocial stressors can impair everyday functioning and may contribute to the development of neurodegenerative diseases such as Alzheimer's disease. This article outlines neurocognitive consequences of everyday stressors in PLWH. While some lifestyle factors can exacerbate inflammatory processes and promote negative neurocognitive health, novel interventions including the use of cannabinoids may be neuroprotective for aging PLWH who are at risk for elevated levels of inflammation from comorbidities. Studies of integrated neurocognitive rehabilitation strategies targeting lifestyle factors are promising for improving neurocognitive health, and may over time, reduce the risk of Alzheimer's disease in PLWH.

Psychological resilience is an independent correlate of health-related quality of life in middle-aged and older adults with HIV in the Deep South

Older people living with HIV (PLWH) are at risk for poorer health-related quality of life (HRQoL). Psychological resilience may protect HRQoL in this population. The sample included 174 predominately African American PLWH (age 40-73). Results indicated associations between resilience, socioeconomic status, cognitive performance, instrumental activities of daily living, personality, and depressive symptoms. HIV factors (e.g. viral load, duration of HIV) were not associated with resilience. Adjusting for confounders, resilience was associated with mental HRQoL. Understanding factors associated with resilience among older PLWH and the translation of resilience to HRQoL may inform interventions to improve well-being among individuals aging with HIV.

Mini-Mental State Examination and Montreal Cognitive Assessment as Tools for Following Cognitive Changes in Alzheimer’s Disease Neuroimaging Initiative Participants

Background: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) are two commonly used cognitive screening and diagnostic tools. Objective: Our goal was to assess their efficacy for monitoring cognitive changes, as well as the correlation between the two tests. Methods: At baseline, participants in the Alzheimer’s Disease Neuroimaging Initiative (ADNI) were divided into four groups based on their cognitive diagnoses: healthy control (HC), early mild cognitive impairment (EMCI), late mild cognitive impairment (LMCI), and Alzheimer’s disease (AD). MMSE or MoCA scores were compared among the four groups using an analysis of variance (ANOVA) model with repeated measures with post-hoc Bonferroni correction. For those participants who had both MMSE and MoCA assessments done, a Pearson correlation analysis was performed between the two assessments for each visit. Results: The MMSE scores were significantly different among the four groups at baseline, which was true for each of the three annual follow-up visits. By contrast, the MoCA scores were not significantly different between HC and EMCI groups at either baseline or any of the follow-up visits. For participants with a diagnosis of LMCI, the cognitive performance deteriorated in a linear manner 12 months after the baseline, which was independent of MMSE or MoCA. At last, the MMSE scores were moderately related to MoCA scores, which got stronger along with the time of follow-up. Conclusion: MMSE and MoCA are comparable as cognitive assessment tools to monitor cognitive changes. In addition, the measurements of MMSE and MoCA are moderately correlated for the follow-up visits.

Immediate and Long-Term Effects of a Computerized Cognitive Rehabilitation Therapy on Cognitive Function in People Living with HIV in Iran: A Single-Blind Two-Arm Parallel Randomized Controlled Trial

ABSTRACT

Up to 50% of people with HIV (PWH) experience neurocognitive impairments (NCIs) that can interfere with everyday functioning and reduce quality of life. To address this problem, this study examined the immediate and long-term efficacy of computerized cognitive rehabilitation therapy (CCRT) on cognitive function in PWH in Tehran, Iran. Thirty PWH with NCI engaged in 24 biweekly 90-min CCRT sessions. A control group of 30 PWH and NCI received treatment-as-usual, but no CCRT. The cognitive rehabilitation protocol focused on attention, visual memory, nonverbal learning, and planning. Pretest, posttest, and follow-up cognitive measurements showed that the designed CCRT protocol was effective in improving performance in selected cognitive domains along with the global neurocognitive performance scores of PWH. These findings suggest that this CCRT protocol be considered as part of a treatment plan to address cognitive impairment for PWH. Implications for clinical practice and research are provided.

Cognitive reserve attenuates the association between HIV serostatus and cognitive performance in adults living in the deep South

Cognitive reserve has shown evidence of mitigating HIV-related effects on cognition in people living with HIV (PWH). In a sample of adults residing in the Deep South, an underrepresented subgroup in the neuroAIDS literature, we assessed the association between HIV serostatus and age on processing speed, visual attention, executive function, and episodic memory and the attenuating effect of cognitive reserve. Adults (n = 138; 72 PWH; M age = 58.7 years, SD = 7.9 years; 75% nonwhite race) were recruited from a university clinic and the community. Verbal abilities served as a proxy for cognitive reserve. Regressions accounting for race, alcohol usage, and depressive symptoms were conducted for each cognitive outcome. Indirect effects were tested using the PROCESS macro. Being HIV seropositive was associated with worse executive function (b = -1.04, SE = 0.38, p = .007) and episodic memory (b = -39.94, SE = 12.54, p = .002) performance. Every year of age above the mean and nonwhite race was associated with worse cognitive performance (ps < .05). The addition of cognitive reserve to the model attenuated the HIV serostatus associations with executive function (BC 95% CI -0.770, -0.001) along with most associations between race and cognitive outcomes. Age associations remained for all cognitive outcomes (ps < .05). Findings highlight the importance of including verbal ability proxies of cognitive reserve when assessing cognition in PWH. Highlighting modifiable cognitive processes, such as cognitive reserve, will further the development of targeted cognitive interventions in this at-risk population.

Internalized HIV-Related Stigma and Neurocognitive Functioning Among Women Living with HIV

The prevalence of HIV-associated neurocognitive impairment persists despite highly effective antiretroviral therapy (ART). In this study we explore the role of internalized stigma, acceptance of negative societal characterizations, and perceptions about people living with HIV (PLWH) on neurocognitive functioning (executive function, learning, memory, attention/working memory, psychomotor speed, fluency, motor skills) in a national cohort of women living with HIV (WLWH) in the United States. We utilized observational data from a multicenter study of WLWH who are mostly African American living in low-resource settings. Neurocognitive function was measured using an eight-test battery. A multiple linear regression model was constructed to investigate the relationship between internalized stigma and overall neurocognitive functioning (mean of all neurocognitive domain standardized T-scores), adjusting for age, education, race, previous neuropsychological battery scores, illicit drug use, viral load, and years on ART. Our analysis revealed that internalized HIV-related stigma is significantly associated with worse performance on individual domain tests and overall neurocognitive performance (B = 0.27, t = 2.50, p = 0.01). This suggests HIV-related internalized stigma may be negatively associated with neurocognitive functioning for WLWH. This finding highlights a specific psychosocial factor associated with poor neurocognitive function that may be targeted to better promote the health of PLWH. Future research on the longitudinal relationship between these variables and the effects of other stigma dimensions on poor neurocognitive function would provide further insights into the pathways explaining the relationship between internalized stigma and neurocognition.

Correlates of subjective and objective everyday functioning in middle-aged and older adults with human immunodeficiency virus

People with human immunodeficiency virus (HIV) (PWH) are at an increased risk for impaired everyday functioning and they may also experience poor awareness of their functional status. This study identified factors associated with (1) subjective and objective instrumental activities of daily living (IADLs) and (2) awareness of functional capacity in PWH. In this cross-sectional study, 236 PWH completed a neurobehavioral assessment, including self-report and performance-based measures of IADLs. Multiple regressions were performed to identify demographic, personality, and cognitive factors contributing to subjective and objective evaluation of everyday functioning, as well as discrepancy between self-report and performance-based measures of IADLs. Results indicated that increased depression was associated with worsened self-report of everyday functioning but not performance of IADLs. Cognitive function and age were associated with IADL performance. Most participants (58.1%) demonstrated a discrepancy between self-report and actual performance of IADLs. Worse processing speed was correlated with greater discrepancy. Inaccurate self-reporters had worse overall cognitive functioning and lower levels of personality traits, including openness, conscientiousness, and agreeableness. In conclusion, self-report and actual performance of IADLs in PWH is influenced by different factors. Self-report may be more affected by psychological variables, such as mood and personality, while actual performance is more sensitive to age and cognitive function.

The Association Between Leisure Activity Engagement and Health-Related Quality of Life in Middle-Aged and Older People With HIV

BACKGROUND AND OBJECTIVES

Middle-aged and older adults with human immunodeficiency virus (HIV) are at risk for decreased health-related quality of life (HRQoL), which may be improved by engaging in leisure activities. We examined associations between HRQoL and participation in cognitive, physical, social, and passive leisure activities, and whether depressive symptoms mediated these relationships. Wilson and Cleary's conceptual model of HRQoL guided this study.

RESEARCH DESIGN AND METHODS

In this cross-sectional observational study, we enrolled 174 adults living with HIV aged 40 and older (M = 51.3, SD = 7.03). Participants completed assessments of leisure activities, depressive symptoms, and HRQoL. Data were analyzed using Spearman's rho correlations, hierarchal multiple regression, and mediation analyses.

RESULTS

Greater engagement in physical activities was associated with higher physical HRQoL (b = 2.02, p < .05). Greater engagement in social activities was associated with both higher physical (b = 1.44, p < .05) and mental HRQoL (b = 1.95, p < .01). However, all associations between leisure activities and HRQoL were fully attenuated by depressive symptoms. Cognitive and passive leisure activities were not significantly correlated with HRQoL. Mediation analyses confirmed that depressive symptoms were the mediator mechanism by which social activities affected mental and physical HRQoL.

DISCUSSION AND IMPLICATIONS

More frequent engagement in physical and social leisure activities is associated with better HRQoL, and social leisure activities improve HRQoL via their impact on mood. Interventions to increase leisure activities, especially among people living with HIV who have poorer affective functioning, may be the most effective approach to improving HRQoL.

Polypharmacy Is Associated With Falls in Women With and Without HIV

BACKGROUND

Aging in people with HIV is associated with increased risk of developing synergistic conditions such as neurocognitive impairment, polypharmacy, and falls. We assessed associations between polypharmacy (use of 5 or more non-ART medications), use of neurocognitive adverse effects (NCAE) medications, and odds of falls in women with HIV (WWH) and without HIV (HIV-).

METHODS

Self-reported falls and medication use data were contributed semiannually by 1872 (1315 WWH and 557 HIV-) Women's Interagency HIV Study participants between 2014 and 2016. Polypharmacy and NCAE medication use were evaluated separately and jointly in multivariable models to assess their independent contributions to single and multiple falls risk.

RESULTS

The proportion of women who reported any fall was similar by HIV status (19%). WWH reported both greater polypharmacy (51% vs. 41%; P < 0.001) and NCAE medication use (44% vs. 37%; P = 0.01) than HIV- women. Polypharmacy conferred elevated odds of single fall [adjusted odds ratio (aOR) 1.67, 95% CI: 1.36 to 2.06; P < 0.001] and multiple falls (aOR 2.31, 95% CI: 1.83 to 2.93; P < 0.001); the results for NCAE medications and falls were similar. Both polypharmacy and number of NCAE medications remained strongly and independently associated with falls in multivariable models adjusted for HIV serostatus, study site, sociodemographics, clinical characteristics, and substance use.

CONCLUSIONS

Polypharmacy and NCAE medication use were greater among WWH compared with HIV-, and both were independently and incrementally related to falls. Deprescribing and avoidance of medications with NCAEs may be an important consideration for reducing fall risk among WWH and sociodemographically similar women without HIV.

Transportation Barriers and Health-Related Quality of Life in a Sample of Middle-Aged and Older Adults Living with HIV in the Deep South

Access to reliable transportation is a social determinant of health imperative for disease management for those aging with HIV/AIDS. To what degree transportation barriers are associated with health-related quality of life (HRQOL) in middle-aged and older people living with HIV (PWH) in the Deep South region of the United States is presently unknown. PWH (n = 261, age range = 39 to 73 years old, 80.1% African American, 64.4% male) were recruited from an academic medical center in the Deep South. Variables included sociodemographics, HIV characteristics, depressive symptoms, HRQOL, and perceived transportation barriers. Spearman rho correlations and linear regressions accounting for covariates were conducted. After accounting for covariates, greater perceived transportation barriers were associated with worse health perceptions, pain, social functioning, health distress, and health transitions. Access to reliable transportation is a key factor in improving health for PWH. Considerations for healthcare and traffic safety are discussed.

Emerging directions of cognitive aging with HIV: practice and policy implications for social work

Cognitive impairments have been endemic to the HIV epidemic since its beginning and persist to this day. These impairments are attributed to HIV-induced neuroinflammation, the long-term effects of combination antiretroviral therapy, lifestyle factors (e.g., sedentary behavior, substance use), neuro-comorbidities (e.g., depression), age-associated comorbidities (e.g., heart disease, hypertension), and others causes. Normal aging and lifestyle also contribute to the development of cognitive impairment. Regardless of the etiology, such cognitive impairments interfere with HIV care (e.g., medication adherence) and everyday functioning (e.g., driving safely, financial management). With more than half of people with HIV (PWH) 50 years and older, and ~45% of all PWH meeting the criteria for HIV-Associated Neurocognitive Disorder (HAND), those aging PWH are more vulnerable for developing cognitive impairment. This article provides an update to a social work model to identify and monitor PWH for cognitive impairment. Within this update, the state of the science on protecting brain health and cognitive reserve within the context of neuroHIV is also presented. From this, implications for practice and policy to promote successful cognitive functioning in older PWH are provided.

Olfactory Dysfunction in Aging African American and Caucasian Men With HIV: A Pilot Study

ABSTRACT

As people age with HIV, olfactory dysfunctions may become more pronounced, especially for African Americans who are predisposed to declines in olfaction. In this cross-sectional study, 34 middle-age and older African American and 17 Caucasian men living with HIV were administered two objective olfactory measures (UPSIT). In the Smell Threshold Test, compared to the HIV-negative age norms, adults living with HIV were significantly less able to detect a lower threshold smell. In the University of Pennsylvania Smell Identification Test, compared to the HIV-negative age norms, adults living with HIV were significantly less able to correctly identify odors; furthermore, using such norms, African Americans with HIV were less likely to correctly identify odors compared to Caucasians with HIV. Since the literature indicates that African Americans have a stronger attraction for salty and sweet foods, such olfactory dysfunction may contribute to poor eating habits, potentially predisposing this population to additional health problems.

A Randomized Clinical Trial on the Impact of Individually Targeted Computerized Cognitive Training on Quality of Life Indicators in Adults With HIV-Associated Neurocognitive Disorder in the Southeastern United States

ABSTRACT

HIV-associated neurocognitive disorder (HAND) is experienced by 30% to 50% of people living with HIV (PLWH), potentially affecting their quality of life (QoL). In the Training on Purpose Study, we investigated whether targeted cognitive training can improve QoL in PLWH with HAND. Using a two-group experimental design, we randomized 109 adults with HAND to either (a) the Individualized-Targeted Cognitive Training group or (b) a no-contact control group. Those in the training group were assigned 10 hr of cognitive training per two selected cognitive domains (20 hr total) for which impairment was observed. Overall, two patterns emerged. First, significant improvements in measures of everyday cognitive complaints, depression, and mental health were consistently observed after the completion of many cognitive training protocols. Second, immediate and delayed spatial learning and memory training resulted in more significant indicators of QoL improvements compared with the other cognitive domain trainings. The findings suggest that some types of cognitive training may have advantages over others in improving aspects of QoL.

Can Diet Supplements of Macular Pigment of Lutein, Zeaxanthin, and Meso-zeaxanthin Affect Cognition?

Background: Lutein (L), zeaxanthin (Z), and meso-zeaxanthin (MZ) are collectively called macular pigment. MZ can be converted from L in the macula. In the recent decade, many studies have been performed to investigate the effects for taking carotenoids, especially L and Z or L, Z, and MZ, as diet supplements on human health. Objective: We examined if diet supplements of L + Z or L + Z + MZ have effects on cognitive function in adults. Methods: A systemic literature search was performed in March 2021 with the following keywords: lutein, zeaxanthin, meso-zeaxanthin, cognition, cognitive, and macular pigment. The searched databases included Medline EBSCOhost, Scopus, Elsevier, Cochrane Library, ProQuest, and ClinicalTrials.gov. Findings from eight clinical trials were presented as the strongest evidence on the studied topic. Results: Most studies have found that macular pigments (L + Z) in blood or macula are positively correlated with cognitive performance. As an index of the amount of macular pigments in the brain, macular pigment optical density is related to cognitive performance in adults. In addition, there is an inverse relationship between a higher amount of macular pigment in the blood and lower risk of mild cognitive impairments or Alzheimer’s disease. Based on the findings from the clinical trials, diet supplements of L + Z or L + Z + MZ are associated with improved cognition in adults. Conclusion: The diet supplements of L + Z or L + Z+MZ are associated with better cognitive functioning, which may be via their beneficial effects on the vision.

Examining the Acceptability of a Resilience Building Intervention Among Adults Aging With HIV

ABSTRACT

Few interventions have targeted resilience resources in people living with HIV (PLWH). We tested the acceptability of an existing resilience intervention in middle-age and older PLWH. Fourteen PLWH attended one 3-hr group session, which included videos, quizzes, and written activities. Participants provided quantitative and qualitative feedback. The mean acceptability rating was 8.71 (1.27) on a 10-point scale. A majority of participants reported that the intervention was an appropriate length; that it improved their resilience, mood, and ability to manage HIV; and that they would likely continue using the tools. Average content retention accuracy was 75% (12.66). Qualitative feedback suggested addressing HIV-specific stressors, including disclosure concerns, stigma, health concerns, and treatment adherence. The resilience intervention was deemed highly acceptable among older PLWH. Uptake may increase by addressing HIV-specific stressors and improving comprehensibility. Future research should further refine and test the efficacy of a modified version of the intervention.

Differential Associations Between BDNF and Memory Across Older Black and White Adults With HIV Disease

BACKGROUND

Brain-derived neurotrophic factor (BDNF) shows consistent associations with memory across many clinical populations, including dementia. Less is understood about the association between BDNF and memory functioning in people living with HIV (PWH).

METHODS

A sample of 173 adults aged 50+ (n = 100 HIV+ and n = 73 HIV seronegative) completed a comprehensive neurobehavioral assessment and blood draw. Linear regressions predicting memory domains (learning, delayed recall, and recognition) were conducted including race (White vs. Black/African American), HIV status, BDNF, and their interactions.

RESULTS

For learning and delayed recall, significant (P < 0.05) main effects for race and interactions for BDNF x race and HIV status x race were found, whereas for recognition, only a BDNF x race interaction emerged. In adjusted models, BDNF x race interactions remained for learning and delayed recall. To determine effect size, correlations were conducted between BDNF and memory domains stratified by HIV serostatus and race, and small-medium associations between BDNF and learning and delayed recall (rho = 0.29, P < 0.01; rho = 0.22, P = 0.045), but no recognition (rho = 0.12, P = 0.29) were found among Black/African American PWH. BDNF was not significantly associated with memory domains in White PWH or either HIV- sample. Follow-up analyses showed BDNF-memory specificity, such that race X BDNF interactions did not emerge for other cognitive domains.

CONCLUSIONS

While limited by cross-sectional design among a small sample, particularly of White individuals, results indicate that BDNF may serve as a promising biomarker reflecting memory functioning in PWH, particularly Black/African Americans. Further work is needed to replicate findings and determine mechanisms for racial differences in BDNF associations with memory.

A Pilot Study of Self-Rated and Psychophysical Olfactory Dysfunction in Men Living with HIV

Background

Olfactory loss is associated with poor quality of life, malnutrition, and increased risk of depression, yet few studies have examined unawareness of olfactory dysfunction in men living with HIV (MLWH).

Method

MLWH (n = 51) completed olfaction self-ratings, psychophysical odor identification testing, cognitive measures, and questionnaires assessing smell habits, mood, cognitive failures, and quality of life. The sensitivity and specificity of olfactory self-ratings was calculated, and t-tests were used to examine factors contributing to discordance between self-rated and psychophysical olfaction dysfunction.

Results

We found that 33.3% (17 of 51 MLWH) of our sample demonstrated discordance between self-reported and psychophysical olfactory scores. Those unaware of olfaction dysfunction reported using less scented products in daily life but showed no other differences across demographic, clinical, or cognitive indices.

Conclusions

Our results cohere with prior studies of cognitively normal older adults, traumatic brain injury, and Parkinson's disease, which found that olfactory self-ratings may inadequately capture the full range of a person's olfactory status. Our work extends these findings to MLWH, with discordance rates ranging from 35 to 61% for self-rated and psychophysical olfactory dysfunction.

Implications

Given the differing rates of self-rated and psychophysical olfaction in our sample, psychophysical olfactory measures may be useful to consider in the neuropsychological assessment and clinical care of PLWH.

Rationale and protocol for a pilot randomized controlled trial of a cognitive prescription intervention for reducing dementia risk factors among African Americans

BACKGROUND & PURPOSE

African Americans (AAs) are twice as likely to develop dementia than Whites, which may be driven by poorer dementia knowledge and lifestyle factors. This article provides the rationale and protocol for a pilot clinical trial examining a tailored multi-domain lifestyle modification intervention in middle-aged and older AAs. This study will explore the feasibility and efficacy of individualized Cognitive Prescriptions (CogRx) which target five domains: physical activity, cognitive activity, diet, sleep, and social activity. Theoretical underpinnings include Social Cognitive Theory and the Health Belief Model, which suggest that tailored risk factor information, goal-setting, and outcome expectations along with addressing self-efficacy and barriers will promote behavior change.

STUDY DESIGN

This study plans to enroll 150 community-dwelling AA participants aged 45-65 without significant cognitive impairment. After baseline assessment including data-driven assessment of deficiencies in each of the five CogRx domains, participants are randomized with equal allocation to either: psychoeducation + CogRx, psychoeducation only, or no-contact control. The psychoeducation and CogRx groups receive general psychoeducation on dementia prevalence, prognosis, and risk factors, while the CogRx group also receives information on their risk factor profile and develops a tailored 3-month intervention plan, consisting of simple evidence-based strategies to implement. The CogRx condition receives text-messaging reminders and adherence queries and provides feedback on this program.

CONCLUSION

This study tests a novel multi-domain dementia prevention intervention and has several strengths, including enrolling middle-aged AAs with a focus on prevention, assessing adherence and self-efficacy, tailoring the intervention, and examining dementia knowledge. The goal is to yield new perspectives on person-centered dementia prevention approaches in diverse populations, and ultimately impact clinical and public health recommendations for maintaining cognitive health, thereby reducing disparities in dementia. Modifications to study design due to COVID-19 and future directions are discussed.

Socioeconomic, Psychosocial, and Clinical Factors Associated With Employment in Women With HIV in the United States: A Correlational Study

ABSTRACT

Employment is a social determinant of health, and women living with HIV (WLWH) are often underemployed. This correlational study examined the socioeconomic, psychosocial, and clinical factors associated with employment among WLWH (n = 1,357) and women at risk for HIV (n = 560). Descriptive and inferential statistics were used to evaluate factors associated with employment status. Employment was associated (p ≤ .05) with better socioeconomic status and quality of life (QOL), less tobacco and substance use, and better physical, psychological, and cognitive health. Among WLWH, employment was associated (p ≤ .05) with improved adherence to HIV care visits and HIV RNA viral suppression. Using multivariable regression modeling, differences were found between WLWH and women at risk for HIV. Among WLWH, household income, QOL, education, and time providing childcare remained associated with employment in adjusted multivariable analyses (R2 = .272, p < .001). A better understanding of the psychosocial and structural factors affecting employment is needed to reduce occupational disparities among WLWH.

Maternal-infant bonding for the opioid exposed dyad: A rodgers' evolutionary concept analysis

AIM

This concept analysis aimed to offer insight into how opioid exposure affects the quality and construction of the maternal-infant bond.

BACKGROUND

Maternal-infant bonding can be influenced by maternal opioid use disorder and the neonatal intensive care unit environment. Many interventions for mothers with opioid use disorder focus on enhancing parental skills, but often the emotional and relational features of the maternal-infant bond have been overlooked.

DATA SOURCE

Literature from Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, PubMed, and PsycINFO published from January 2011 to June 2021 using "attachment theory," "mother-infant attachment," "maternal-infant bonding," "neonatal opioid withdrawal syndrome," and "neonatal abstinence syndrome" as key terms.

REVIEW METHODS

Rodgers' method of concept analysis was used to determine the antecedents, attributes, and consequences of maternal-infant bonding.

RESULTS

The key attributes of bonding for the opioid-exposed mother-infant dyad are engaged mothering, recognition of risk, affection, and respectful maternity care. The antecedents are closeness, selflessness, and purposeful touch. The consequences are sobriety, custody, love, and security.

A-61 Predictors of Subjective and Objective Everyday Functioning in Middle-Aged and Older Adults with HIV

Objective

Older adults with HIV are at increased risk for difficulties with instrumental activities of daily living (IADLs). Awareness of their functional capacity has emerged as an important area for research, but it is not well studied in PWH. The purpose of this study is: (1) to identify factors associated with subjective and objective IADL difficulty in PWH and (2) to identify factors associated with under- or over-reporting of IADL difficulties.

Methods

This cross-sectional study included 261 adults with HIV. Participants completed a neuropsychological battery, self-report and performance-based measures of IADLs. Self-report measures included the Patient’s Assessment of Own Functioning Inventory (PAOFI) and the Lawton and Brody IADL Questionnaire. The Timed Instrumental Activities of Daily Living (TIADL) task was used as an objective measure. Hierarchical multiple regressions were performed to identify factors associated with subjective and objective assessment of everyday functioning as well as factors associated with discrepancy between self-report and actual performance of IADLS.

Results

On the PAOFI, higher depression (p = 0.001), lower conscientiousness (p &gt; 0.001), and better processing speed (p = 0.017) predicted worse functioning. On the Lawton and Brody, higher depression (p = 0.049) predicted of worse functioning. On the TIADL, older age (p = 0.1), lower WRAT-4 score (p &gt; 0.001), worse processing speed (p &gt; 0.001), and worse motor function (p = 0.1) were associated with worse performance. Processing speed predicted discrepancy between subjective and objective performance of IADLs (p = 0.1).

Conclusions

Several demographic, cognitive, and personality variables are associated with worse subjective and objective everyday functioning, as well as an individual’s ability to accurately self-appraise their functional capacity.

Driving habits, cognition, and health-related quality of life in middle-aged and older adults with HIV

Cognitive impairment is known to increase with aging in people living with HIV (PLWH). Impairment in cognitive domains required for safe driving may put PLWH at risk for poor driving outcomes, decreased mobility, and health-related quality of life (HRQoL). This study described the driving behaviors of middle-aged and older PLWH and examined correlations between driving behaviors and cognitive functioning (Aim 1), and driving behaviors and HRQoL domains (Aim 2). A sample of 260 PLWH ages 40 and older completed a comprehensive assessment including a battery of cognitive tests, an HRQoL measure, and a measure of self-reported driving habits. Associations between driving habits, cognitive function, and HRQoL domains were examined. While 212 (81.54%) participants reported currently driving, only 166 (63.85%) possessed a driver's license. Several significant correlations emerged between driving habits and both cognitive and HRQoL variables, with a general pattern suggesting that current greater driving exposure was associated with better cognitive functioning and HRQoL. Given consistent associations that emerged between the social functioning HRQoL domain and several driving habits, multivariable regression was conducted to examine the unique association between an index of greater driving exposure (i.e., days driven per week) and social functioning, adjusting for potential confounders (race, income, education, depression, and global cognition). Results showed that more days driven per week was a significant, independent correlate of higher social functioning. Understanding the factors underlying driving behaviors in PLWH may contribute to interventions to promote better mobility and improved access to care.

High Frequency of Recurrent Falls Among Prefrail and Frail Women With and Without HIV

BACKGROUND

Frailty may occur at younger ages among HIV+ populations. We evaluated associations of the frailty status with self-reported single and recurrent falls in the Women's Interagency HIV Study (WIHS).

METHODS

The frailty status was defined using the Fried Frailty Phenotype (FFP) among 897 HIV+ and 392 HIV- women; median age 53 years. Women were classified as robust (FFP 0), prefrail (FFP 1-2), and frail (FFP 3-5). Stepwise logistic regression models adjusting for the HIV status and study site were fit to evaluate associations of the FFP with self-reported single (1 vs. 0) and recurrent falls (≥2 vs. 0) over the prior 12 months.

RESULTS

HIV+ women were less likely to be frail (9% vs. 14% vs. P = 0.009), but frequency of falls did not differ by the HIV status. In multivariate analyses, recurrent falls were more common among prefrail [adjusted odds ratio (AOR) 2.23, 95% confidence interval (CI): 1.40 to 3.57, P = 0.0008] and frail (AOR 3.61, 95% CI: 1.90 to 6.89, P < 0.0001) than robust women. Among HIV+ women, single (AOR 2.88, 95% CI: 1.16 to 7.20, P = 0.023) and recurrent falls (AOR 3.50, 95% CI: 1.24 to 9.88, P = 0.018) were more common among those who were frail; recurrent, but not single falls, were more common among prefrail than robust HIV+ women (AOR 2.00, 95% CI: 1.03 to 3.91, P = 0.042).

CONCLUSIONS

HIV+ women were less likely to be frail. Compared with robust women, prefrail and frail women with and without HIV were more likely to experience single or recurrent falls within a 12-month period. Additional studies are needed to develop interventions that decrease development of frailty and reduce risk of recurrent falls among HIV+ women.
