Critical, and not functional, health literacy is associated with missed HIV clinic visits in adults and older adults living with HIV in the Deep South

Barriers and opportunities for the mental health of LGBT older adults and older people living with HIV: a systematic literature review

OBJECTIVE

LGBT older adults and older people living with HIV (PLWH) experience a disproportionate burden of behavioral health conditions compared to their heterosexual, cisgender, and HIV-negative peers. This study intends to systematically review the literature regarding accessing mental health care among LGBT older adults and older PLWH.

METHODS

This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement framework. Three databases were searched using Boolean search strings, and inclusion/exclusion criteria were developed and applied to the search outcomes to appropriately narrow results. Article quality and evidence of bias were evaluated using the National Heart, Lung, and Blood Institute (NHLBI) quality-assessment tool, and the Critical Appraisal Skills Program (CASP) assessment tool, two instruments used to help reviewers in assessing for internal validity of studies. Two independent researchers coded the articles for themes, and consensus was reached on theme grouping through an iterative process.

RESULTS

Out of 2,031 articles initially screened, 28 met all inclusion criteria and advanced to final analysis. Several key themes emerged, including a lack of provider competency in caring for LGBT patients, lower rates of insurance coverage, greater mental health burden, social and structural determinants of health, policy solutions, and technology and health literacy.

CONCLUSION

There were several domains identified in the literature as barriers to accessing mental healthcare, as well as opportunities to better attend to the mental health needs of these populations. Provider training, implementing health technology solutions, and enacting public policy changes could improve mental health outcomes.

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.

Risk Factors of Cognitive Decline in Older Caregivers With HIV: An Emerging Hypothesis

ABSTRACT

People with HIV (PWH) are living longer and healthier lives; thanks to combination antiretroviral therapy. As many PWH age, they find themselves providing care to family members and friends, just as their counterparts without HIV. The literature indicates that becoming a caregiver creates conditions that compromise one's cognitive function. Additionally, nearly 45% of all PWH experience HIV-associated neurocognitive disorder and are already vulnerable to cognitive impairment due to HIV, aging, and accompanying health conditions, and lifestyle factors. Given what is known, we assert that caregivers with HIV, especially as they age, are at additional risk for developing cognitive impairments. The purpose of this commentary was to briefly examine the juxtaposition between cognitive vulnerability of caregiving and the cognitive vulnerability of aging with HIV. Potential factors contributing to impaired cognition include stress, lack of social support, stigma, lifestyle, and comorbidities. Implications for clinical practice and research are provided.

A Systematic Review of Factors Critical for HIV Health Literacy, ART Adherence and Retention in Care in the U.S. for Racial and Ethnic Minorities

Despite advances in antiretroviral treatment (ART), the HIV epidemic persists in the United States (U.S.), with inadequate adherence to treatment and care a major barrier to ending the epidemic. Health literacy is a critical factor in maximizing ART adherence and healthcare utilization, especially among vulnerable populations, including racial and ethnic minorities. This U.S-based systematic review examines psychosocial variables influencing health literacy among persons with HIV (PWH), with a focus on racial and ethnic minorities. Although findings are limited, some studies showed that HIV-related stigma, self-efficacy, and patient trust in providers mediate the relationship between health literacy and both ART adherence and HIV care retention. To inform effective, equitable health literacy interventions to promote adherence to HIV treatment and care, further research is needed to understand the factors driving the relationship between health literacy and HIV outcomes. Such work may broaden our understanding of health literacy in the context of racial equity.

Neurocognitive performance differences between black and white individuals with HIV disease are mediated by health literacy

Objective:Health disparities are evident for Black Americans with HIV disease, who are disproportionally affected by the epidemic in the United States. The current study investigated whether the higher rates of neurocognitive impairment in Black Americans with HIV disease may be at least partly attributable to health literacy, which is a potentially modifiable factor. Method: Participants were 61 White and 25 Black participants (ages 27-70) with HIV disease who were enrolled in studies at an urban academic center in Southern California. Neurocognitive function was assessed by an age-adjusted global score from the Cogstate battery. Health literacy was measured by a composite score derived from the Rapid Estimate of Adult Literacy in Medicine, Newest Vital Sign, and 3-Brief. Results: Bootstrap confidence interval mediation analyses showed that health literacy was a significant mediator of the relationship between race and neurocognition; that is, there were no direct ethnoracial differences in neurocognition after accounting for health literacy. A follow-up model to confirm the directionality of this association demonstrated that neurocognition was not a significant mediator of the relationship between race and health literacy. Conclusions: Low health literacy may contribute to the higher rates of neurocognitive impairment for Black Americans with HIV disease. Future studies might examine the possible mechanism of this mediating relationship (e.g., access to health information, health behaviors, socioeconomics) and determine whether culturally tailored interventions that improve health literacy also confer broader brain health benefits for Black Americans with HIV disease.

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 cognition and creativity among persons with HIV disease referred for neuropsychological evaluation

Creativity can help people to innovate, overcome obstacles, and successfully navigate challenges in daily life. Some aspects of creativity rely on the prefrontostriatal loops and executive functions, which can be compromised in persons with HIV (PWH). This pilot study examined whether neuropsychological functioning plays a role in creativity in PWH. A consecutive series of 41 PWH who were referred to an urban neuropsychology clinic in southeastern Texas were enrolled. Participants completed the Abbreviated Torrance Test for Adults (ATTA) to measure creativity, from which standardized creativity scores of fluency, originality, elaboration, and flexibility were derived. Participants also completed several measures of everyday functioning and a brief clinical neuropsychological battery measuring executive functions, motor skills, memory, and visuoconstruction. Global neuropsychological functioning showed a large, positive association with ATTA creativity performance that did not vary meaningfully by creativity domain and was independent of premorbid IQ. ATTA creativity scores were not associated with any measure of everyday functioning. Findings from this pilot study suggest that higher levels of neuropsychological functioning may support multiple dimensions of creativity in adults with HIV disease. Future studies might examine whether creativity moderates the association between HIV-associated neurocognitive impairment and various health behaviors (e.g., adherence, appointment attendance).

The cascade of care of HIV after one year of follow-up in a cohort of HIV-positive adult patients in three health settings of Morrumbene in rural Mozambique

OBJECTIVE

To assess the state of the retention in care of HIV patients in three health settings in Morrumbene, a rural district of Inhambane Province, Mozambique. We evaluated potential factors associated with early loss to follow-up (LTFU), retention in care and ART adherence during the first year of follow-up.

MATERIAL AND METHODS

Retrospective, cross-sectional, observational study. We collected data on patients diagnosed with HIV infection in 2017 in two permanent clinics and one mobile clinic. Demographic, clinical, immunological and therapeutic data were retrieved up to December 31st, 2018. Data on follow-up were collected at 6 and 12 months for medical visits and for ART adherence and analysed for factors associated with LTFU, retention in care and adherence to ART by Stata Version 14 and univariate and stepwise multiple unconditional logistic regression models.

RESULTS

In 2017, 960 patients were diagnosed with HIV infection. At 6-month follow-up, 49% attended the medical visit and 157 (25%) adhered to ART. After one year, 34% of patients were available for follow-up, and only 72 patients adhered to ART. In multivariate analysis, factors associated with early LTFU were male sex (p = 0.036) and immediate prescription of ART (p = 0.064). Older age (p < 0.001) and being followed in the mobile clinic (p = 0.001) favoured retention in care. Advanced WHO status (p = 0.005) and being pregnant or breastfeeding showed a negative correlation with adherence to treatment (p = 0.068).

CONCLUSIONS

Only one-third of patients were available for follow-up after one year, and only 13% adhered to ART. Young individuals, men and pregnant/breastfeeding women seem to be particularly at risk for LTFU and non-adherence to treatment.

The Intersection of Cognitive Ability and HIV: A Review of the State of the Nursing Science

ABSTRACT

Neurocognitive problems have been endemic to the HIV epidemic since its beginning. Four decades later, these problems persist, but currently, they are attributed to HIV-induced inflammation, the long-term effects of combination antiretroviral therapy, lifestyle (i.e., physical activity, drug use), psychiatric, and age-associated comorbidities (i.e., heart disease, hypertension). In many cases, persons living with HIV (PLWH) may develop cognitive problems as a function of accelerated or accentuated normal aging and lifestyle rather than HIV itself. Nonetheless, such cognitive impairments can interfere with HIV care, including medication adherence and attending clinic appointments. With more than half of PLWH 50 years and older, and 30%-50% of all PLWH meeting the criteria for HIV-associated neurocognitive disorder, those aging with HIV may be more vulnerable to developing cognitive problems. This state of the science article provides an overview of current issues and provides implications for practice, policy, and research to promote successful cognitive functioning in PLWH.

A Clinical Pilot Study of Spaced Retrieval Practice with a Self-Generation Booster to Improve Health-Related Memory in Persons With HIV Disease

Objective

Spaced retrieval practice (SRP) and self-generation are among the most replicated and effective mnemonic strategies in the cognitive psychology literature, but their benefits have not yet been realized in healthcare settings. This study used a randomized, between-subjects design to examine the hypothesis that SRP with a self-generation booster can improve memory for health-related information among clinically referred persons with HIV (PWH), who often have difficulty acquiring new health knowledge.

Method

A consecutive series of 41 PWH referred to a county-funded urban neuropsychology clinic were enrolled. Participants were randomly assigned to learn four statements about the treatment of a mock infectious disease in either a massed study control condition (n = 20) or an SRP condition (n = 21) in which they received two distributed free recall training tests supplemented with self-generation for missed items. The primary outcome was participants’ free recall of the four treatment statements after a 20-minute delay filled with nonverbal tests.

Results

PWH participants in the SRP condition were four times more likely than controls to recall at least one treatment statement at the 20-minute delay. SRP was not related to post-test recognition or health-related decision-making performance but was associated with moderately better self-efficacy for decision-making.

Conclusions

Findings from this pilot study show the potential of SRP with a self-generation booster to improve learning and memory for health-related information among PWH in clinic.

Misattributions of the source of health-related information in HIV disease

Introduction: Growing access to both legitimate and dubious sources of health information makes accurate source memory increasingly important, yet it may be negatively impacted by conditions that impair prefrontal functioning, including HIV. This study hypothesized that instructions supporting source encoding on a health-related memory task would disproportionately benefit source memory of people with HIV (PWH), and to examine the pattern of source memory errors that are observed.Method: 102 individuals (61 HIV+, 41 HIV-) completed comprehensive neurobehavioral (including health literacy) and neuromedical evaluations, and were randomly assigned to one of two conditions for a health-related memory task: Attend to Source Instructions explicitly participants to attend to the source of health statements presented to them, which were either health professionals or lay-persons, whereas no such instruction was provided in a Control Instructions condition.Results: There was no significant interaction of HIV status by condition or main effect of HIV (ps>.05). There was a main effect of condition whereby those who received Attend to Source Instructions performed better on item-corrected source memory than those in the Control Instructions condition (p =.04). Those who received Control Instructions were more likely to misattribute the source of the health information to a health professional when the correct source was a lay-person (Cohen's d = -0.53), which was correlated with poorer overall cognitive performance (p =.008) and performance-based measures of health literacy (ps<.05).Conclusions: Given that people are rarely reminded to attend to the source of new health information in the real world, the risk for misattributing health information to a qualified health professional in the absence of such instructions raises the concern that people may readily incorporate questionable health recommendations into their health regimen, particularly among persons with poorer cognitive functioning and lower levels of health literacy. This may have significant downstream health consequences such as drug interactions, side effects, and inefficacy.

Neurocognitive Functioning is Associated with Self-Reported and Performance-Based Treatment Management Abilities in People Living with HIV with Low Health Literacy

OBJECTIVE

People living with HIV (PLWH) are at higher risk for poorer neurocognitive functioning and health literacy than uninfected persons, which are associated with worse medical outcomes. Aging research suggests that the effect of neurocognitive functioning on health outcomes may be more pronounced in those with low health literacy. We aimed to determine whether low health literacy might amplify the adverse effects of neurocognitive functioning on treatment management outcomes in 171 PLWH aged 40+.

METHOD

In this cross-sectional, observational study, participants completed a well-validated battery of neurocognitive, health literacy, and treatment management measures. A binary health literacy variable (low vs. adequate) was determined via established cut points on the well-validated health literacy tests. Treatment management outcomes included biomarkers of HIV (i.e., CD4 counts and viral load), self-management of HIV disease (i.e., self-reported medication adherence and self-efficacy for HIV disease management), and performance-based health-related decision-making.

RESULTS

Forty-seven percent of the sample met the criteria for low health literacy. Multivariable regressions adjusting for clinicodemographic (e.g., race, socioeconomic status) covariates revealed significant interactions for self-efficacy for HIV disease management and health-related decision-making, such that neurocognitive functioning was associated with these outcomes among those with low, but not adequate health literacy.

CONCLUSIONS

Findings suggest that low health literacy may increase the vulnerability of PLWH to the adverse effects of neurocognitive impairment on health outcomes, or conversely that adequate health literacy may provide a buffer against the health risks associated neurocognitive impairment. Interventions targeting health literacy in PLWH may mitigate the effects of neurocognitive impairment on health outcomes.

"Worn out": Coping strategies for managing antiretroviral treatment fatigue among urban people of color living with HIV who were recently disengaged from outpatient HIV care

Antiretroviral-related treatment fatigue is inconsistently defined in the literature on barriers to ART adherence. Research suggests that treatment fatigue is a salient challenge for people struggling with antiretroviral therapy adherence, but little is known about how people living with HIV attempt to manage this fatigue. Twenty-seven semi-structured interviews were conducted with low-income people of color living with HIV in NYC that were currently, or recently, disengaged from HIV care. The findings from this exploratory study suggest that treatment fatigue was common and that participants devised personal strategies to overcome it. These strategies included using reminder programs, requesting weekly rather than monthly pill quantities, and taking "pill holidays". The varied nature- and varying levels of effectiveness- of these strategies highlight the need for specific programming to provide tailored support. Future research should examine treatment fatigue as a specific subtype of adherence challenge, and aim to define pill fatigue clearly.
