Low levels of frailty in HIV-positive older adults on antiretroviral therapy in northern Tanzania

Predictors of survival among older adults with HIV in Uganda's AIDS support organization centers of excellence (1987-2023): a retrospective longitudinal study

BACKGROUND

The growing number of older adults living with HIV, facilitated by wider access to antiretroviral therapy (ART), presents unique challenges. This study aims to identify predictors of survival among older persons living with HIV receiving ART in Uganda's AIDS Support Organization Centers of Excellence (1987-2023). Understanding these predictors can inform effective clinical interventions to improve outcomes for this population.

METHODS

This study conducted a retrospective analysis of medical records from 11 TASO centers of excellence in Uganda (1987-2023). Using Cox proportional hazards regression, we identified factors associated with survival among older adults living with HIV. TASO centers of excellence in Entebbe, Gulu, Jinja, Masaka, Masindi, Mbale, Mbarara, Mulago, Rukungiri, Soroti, and Tororo. Cox proportional hazards regression analysis identified factors influencing survival among older persons living with HIV (OPLHIV).

RESULTS

Of the 30,758 OPLHIV medical records analyzed (1987-2023), 72.5% were active on ART, 5.9% had died, 15.2% were lost to follow-up, and 5.6% transferred to other facilities. Survival was significantly associated with: gender (female, HR = 1.19, p < 0.001), marital status (married, HR = 0.99, p < 0.001; separated/divorced, HR = 0.85, p < 0.001), WHO clinical stage (II, HR = 1.66, p < 0.001), viral load (> 200 copies/ml, HR = 1.49, p < 0.001), and ART adherence (fair, HR = 0.94, p = 0.157).

CONCLUSION

Key predictors of survival among Older Adults Living with HIV (OPLHIV) include: female gender, age 50-59, weight 51-70 kg, married status, viral load > 200 copies/ml, WHO HIV clinical stage II, paid employment, and ART adherence. To improve survival outcomes, consistent clinical screenings of WHO clinical stages, viral load, and ART adherence are essential. These measures can guide healthcare providers in making informed treatment decisions to enhance survival and quality of life for OPLHIV in Uganda.

RECOMMENDATIONS

Strengthen routine monitoring of viral load, ART adherence, and WHO clinical staging. Provide targeted support to married and separated/divorced adults to improve their survival chances. Address gender disparities in care to enhance outcomes for females. Focus on maintaining ART adherence and viral suppression to reduce mortality risks.

Application of frailty screening instruments for older people in Sub-Saharan Africa: A scoping review

BACKGROUND

Frailty and frailty screening of older people is increasingly becoming a global public health concern. The health domains and elements that constitute frailty may differ across different settings. The choice of frailty screening instruments can therefore affect frailty diagnosis and potentially delay interventions. The aim of this scoping review is to explore the application of frailty screening instruments among older people in Sub-Saharan Africa.

METHOD

Six databases (Google Scholar, CINAHL, SCOPUS, African Journal online, PubMed, and Africa Index Medicus) were searched for literature published between January 2000 and August 2023. Studies that reported on using frailty screening instruments for older people aged 50 years and above in Sub-Saharan Africa were included in the review.

RESULTS

The search across the six databases yielded 362 results. Seventeen studies from ten countries met the eligibility criteria and were included in this review. Seven frailty screening instruments were identified across the included studies. Frailty screening is gaining attention in Sub-Saharan Africa. Majority of the frailty screening instruments were developed and validated in high-income countries. Only one frailty screening instrument was developed and validated in Sub-Saharan Africa.

CONCLUSION

Considering the impact of frailty on the health and wellbeing of older people, researchers must consider developing and using frailty screening instruments that assess domains that are pertinent to the health and wellbeing of older people in Sub-Saharan Africa.

Prevalence and Correlates of Frailty Among Older People With and Without HIV in Rural Uganda

BACKGROUND

The relationship between HIV and frailty, a predictor of poor outcomes in the face of stressors, remains unknown in older people in sub-Saharan Africa.

METHODS

We analyzed data from the Quality of Life and Ageing with HIV in Rural Uganda cohort study to estimate the prevalence and correlates of frailty among older people with HIV (PWH) on long-term antiretroviral therapy and among age- and sex-matched HIV-uninfected comparators. Frailty was defined as a self-report of 3 or 4 (and pre-frailty as 1 or 2) of the following phenotypic variables: weight loss, exhaustion, low activity, and slowness. We estimated the prevalence of frailty and prefrailty and fitted logistic regression models to estimate the association between HIV and frailty, adjusting for sociodemographic factors, depression, and other comorbidities.

RESULTS

We enrolled 599 participants (49% women) with a mean age of 58 years. PWH had a similar prevalence of frailty (8.1% vs. 10.9%, P = 0.24) but a lower prevalence of prefrailty (54.2% vs. 63.2%, P = 0.03) compared with their HIV-uninfected comparators. In multivariable regression models, people with depression [adjusted odds ratio (AOR) 7.52 (95% CI: 3.67 to 15.40), P < 0.001] and those with ≥1 comorbidities [AOR 3.15 (95% CI: 1.71 to 3.82), P < 0.001] were more likely to be frail. HIV serostatus was not significantly associated with frailty [AOR 0.71 (95% CI: 0.37 to 1.34), P = 0.29].

CONCLUSIONS

Older PWH had a similar prevalence of frailty as those without HIV. These findings call for additional study of the factors that contribute to the robustness of older PWH in sub-Saharan Africa.

Person-centred care for older adults living with HIV in sub-Saharan Africa

More than a fifth of people living with HIV in the US President's Emergency Plan for AIDS Relief-supported programmes are older individuals, defined as aged 50 years and older, yet optimal person-centred models of care for older adults with HIV in sub-Saharan Africa, including screening and treatment for geriatric syndromes and common comorbidities associated with ageing, remain undefined. This Position Paper explores the disproportionate burden of comorbidities and geriatric syndromes faced by older adults with HIV, with a special focus on women. We seek to motivate global interest in improving quality of life for older people with HIV by presenting available research and identifying research gaps for common geriatric syndromes, including frailty and cognitive decline, and multimorbidity among older people with HIV in sub-Saharan Africa. We share two successful models of holistic care for older people with HIV that are ongoing in Zimbabwe and Kenya. Lastly, we provide policy, research, and implementation considerations to best serve this growing population.

Recent advances in HIV-associated neurocognitive disorders: a focus on older adults and sub-Saharan Africa

PURPOSE OF REVIEW

We reviewed recent literature on prevalence and interventional approaches for cognitive impairment in the context of HIV infection alongside current controversies and challenges around its nomenclature, screening, and diagnosis.

RECENT FINDINGS

Prevalence estimates for HIV-associated neurocognitive disorder (HAND) indicate that HAND remains highly prevalent despite combination antiretroviral treatment (cART) widely used. The available data are heterogeneous, particularly in sub-Saharan Africa (SSA) where recent reviews indicate substantial heterogeneity, wide prevalence estimates and lack of data from the majority SSA countries, despite them currently experiencing the greatest burden worldwide of both HIV and HAND.Several alternative approaches to diagnosis and classification of cognitive impairment in HIV have been published, taking into account changing clinical phenotypes.

SUMMARY

Cognitive impairment remains a significant challenge in the care of people living with HIV despite advances in treatment. Ongoing controversies exist around nomenclature and classification, screening measures, and the phenotype and aetiology of observed impairments. Two current areas of research priority and focus include understanding current phenotypes of individuals living and ageing with treated HIV and differing levels of risk for HAND in these phenotypes, alongside the effects of commonly occurring comorbidities.The current evidence base for interventional approaches is limited, but growing. The most promising avenues appear to be multidisciplinary. These are currently focussed on high income settings rather than SSA where the majority of people living with HIV, and affected by cognitive impairment in the context of HIV, currently reside.

Prevalence and Factors Associated With Frailty Among Older Adults Living With HIV Compared to Their Uninfected Peers From the Kenyan Coast

Objectives: a) To document the prevalence and correlates of frailty among older adults living with HIV (OALWH) and their uninfected peers, and b) Investigate HIV status as an independent predictor of frailty. Methods: This cross-sectional study was conducted between 2020 and 2021 at the Kenyan coast among 440 older adults aged ≥50 years (257 OALWH). Frailty was assessed using the Reported Edmonton Frail Scale. Logistic regression was used to examine the correlates of frailty. Results: The prevalence of frailty was significantly higher among OALWH (24%) than their uninfected peers (13%). HIV seropositivity was not independently associated with frailty. Sleeping difficulties, ageism, higher waist/hip ratio, visiting traditional healers, HIV treatment change/interruption, prolonged illness following HIV diagnosis, and self-reported diabetes were significantly associated with higher odds of frailty. Residing in larger households, having higher income, having friends, being male and light physical activities were significantly associated with reduced odds of frailty. Conclusion: The prevalence of frailty is elevated among OALWH; however, factors other than HIV are predominant, particularly psychosocial factors. Multicomponent interventions are needed to prevent/delay and manage frailty in this setting.

Global frailty screening tools: Review and application of frailty screening tools from 2001 to 2023

As the aging population increases globally, health-related issues caused by frailty are gradually coming to light and have become a global health priority. Frailty leads to a significantly increased risk of falls, incapacitation, and death. Early screening leads to better prevention and management of frailty, increasing the possibility of reversing it. Developing assessment tools by incorporating disease states of older adults using effective interventions has become the most effective approach for preventing and controlling frailty. The most direct and effective tool for evaluating debilitating conditions is a frailty screening tool, but because there is no globally recognized gold standard, every country has its own scale for national use. The diversity and usefulness of the frailty screening tool has become a hot topic worldwide. In this article, we reviewed the frailty screening tool published worldwide from January 2001 to June 2023. We focused on several commonly used frailty screening tools. A systematic search was conducted using PubMed database, and the commonly used frailty screening tools were found to be translated and validated in many countries. Disease-specific scales were also selected to fit the disease. Each of the current frailty screening tools are used in different clinical situations, and therefore, the clinical practice applications of these frailty screening tools are summarized graphically to provide the most intuitive screening and reference for clinical practitioners. The frailty screening tools were categorized as (ⅰ) Global Frailty Screening Tools in Common; (ⅱ) Frailty Screening Tools in various countries; (ⅲ) Frailty Screening Tools for various diseases. As science and technology continue to advance, electronic frailty assessment tools have been developed and utilized. In the context of Coronavirus disease 2019 (COVID-19), electronic frailty assessment tools played an important role. This review compares the currently used frailty screenings tools, with a view to enable quick selection of the appropriate scale. However, further improvement and justification of each tool is needed to guide clinical practitioners to make better decisions.

Differences between persons with and without disability in HIV prevalence, testing, treatment, and care cascade in Tanzania: a cross-sectional study using population-based data

BACKGROUND

Persons with disability may have a higher HIV prevalence and be less likely than persons without disability to know their HIV-positive status, access antiretroviral therapy (ART), and suppress their HIV viral load (HIV care cascade). However, studies examining differences between persons with and without disability in HIV prevalence and the HIV care cascade are lacking. Using the Tanzania HIV Impact Survey (THIS) data collected between October 2016 and August 2017, we assessed differences in HIV prevalence and progress towards achieving the 2020 HIV care cascade target between persons with and without disability.

METHODS

Using the Washington Group Short Set (WG-SS) Questions on Disability, we defined disability as having a functional difficulty in any of the six life domains (seeing, hearing, walking/climbing, remembering/ concentrating, self-care, and communicating). We classified respondents as disabled if they responded having either "Some Difficulty", "A lot of difficulties" or "Unable to" in any of the WG-SS Questions. We presented the sample characteristics by disability status and analyzed the achievement of the cascade target by disability status, and sex. We used multivariable logistic regressions, and adjusted for age, sex, rural-urban residence, education, and wealth quintile.

RESULTS

A total of 31,579 respondents aged 15 years and older had HIV test results. Of these 1,831 tested HIV-positive, corresponding to an estimated HIV prevalence of 4.9% (CI: 4.5 - 5.2%) among the adult population in Tanzania. The median age of respondents who tested HIV-positive was 32 years (with IQR of 21-45 years). HIV prevalence was higher (5.7%, 95% CI: 5.3-7.4%) among persons with disability than persons without disability (4.3%, 95% CI: 4.0 - 4.6%). Before adjustment, compared to women without disability, more women with disability were aware of their HIV-positive status (n = 101, 79.0%, 95% CI: 68.0-87.0% versus n = 703, 63.0%, 95% CI: 59.1-66.7%) and accessed ART more frequently (n = 98, 98.7%, 95% CI: 95.3-99.7% versus n = 661, 94.7%, 95% CI: 92.6-96.3%). After adjusting for socio-demographic characteristics, the odds of having HIV and of accessing ART did not differ between persons with and without disability. However, PLHIV with disability had higher odds of being aware of their HIV-positive status (aOR 1.69, 95% 1.05-2.71) than PLHIV without disability. Men living with HIV and with disability had lower odds (aOR = 0.23, 95% CI: 0.06-0.86) to suppress HIV viral loads than their counterparts without disability.

CONCLUSION

We found no significant differences in the odds of having HIV and of accessing ART between persons with and without disability in Tanzania. While PLHIV and disability, were often aware of their HIV-positive status than their non-disabled counterparts, men living with HIV and with disability may have been disadvantaged in having suppressed HIV viral loads. These differences are correctable with disability-inclusive HIV programming. HIV surveys around the world should include questions on disability to measure potential differences in HIV prevalence and in attaining the 2025 HIV care cascade target between persons with and without disability.

Patient priority setting in HIV ageing research: exploring the feasibility of community engagement and involvement in Tanzania

OBJECTIVE

The chronic complications of ageing with HIV are not well studied in sub-Saharan Africa (SSA) where general healthcare resources are limited. We aimed to collaborate with individuals living with HIV aged ≥ 50 years, and community elders (aged ≥ 60 years) living with non-communicable diseases in the Kilimanjaro region of Tanzania in a health research priority-setting exercise.

METHODS

We conducted structured workshops based on broad questions to aid discussion and group-based patient priority setting, alongside discussion of the feasibility of future community research engagement. Participant priorities were tallied and ranked to arrive at core priorities from consensus discussion.

RESULTS

Thirty older people living with HIV and 30 community elders attended separate priority setting workshops. Both groups reported motivation to participate in, conduct, and oversee future studies. In this resource-limited setting, basic needs such as healthcare access were prioritised much higher than specific HIV-complications or chronic disease. Stigma and social isolation were highly prioritised in those living with HIV.

CONCLUSIONS

Community engagement and involvement in HIV and ageing research appears feasible in Tanzania. Ageing and non-communicable disease research should consider the wider context, and lack of basic needs in low-income settings. A greater impact may be achieved with community involvement.

Frailty status and associated factors among older PLHIV in Southern Ethiopia

BACKGROUND

Studies addressing frailty are limited in the global south, including Ethiopia. We estimated the prevalence of frailty and associated factors among older people living with HIV (PLHIV) attending a large Comprehensive Specialized Hospital in southern Ethiopia.

METHODS

A systematic sample of 187 PLHIV and 187 HIV-negative controls > 50 years old were recruited between October 1 and November 30, 2021. Data on socio-demographic, behavioural and clinical characteristics were collected using a structured questionnaire. Frailty assessments were completed using the brief frailty instrument (B-FIT-2), which consists of 6 components. Scoring 5-6 points was frail, 2-4 points were pre-frail and below 2 was considered as non-frail. Logistic regression model was used to measure association between variables.

RESULTS

Median (IQR) age was 53 (50, 80) for PLWH and 59 (55-66) for controls. Prevalence of frailty was 9.1% for PLHIV Versus 5.9% for controls. A significant proportion of PLHIV was pre-frail; 141 (75.4%) compared to controls 110 (58.8%). Pre-frailty status was associated with HIV diagnosis (adjusted odds ratio (aOR) 4.2; 95% CI 1.8-9.9), low age (aOR 0.3; 95% CI 0.1-0.6), lower educational attainment (aOR 2.2; 95% CI 1.0-4.9), being farmer (aOR 3.2; 95% CI 1.0-10.2) and having high or low body mass index (BMI) (aOR 11.3; 95% CI 4.0-25.8). HIV diagnosis (aOR 9.7; 95% CI 1.6-56.8), age (aOR 0.2; 95% CI 0.1-0.7), lower educational attainment (aOR 5.2; 95% CI 1.5-18.2), single status (aOR 4.2; 95% CI 1.3-13.6), farmer (aOR 19.5; 95% CI 3.5-109.1) and high or low BMI (aOR 47.3; 95% CI 13.8-161.9) predicted frailty.

CONCLUSION

A high proportion of frailty and pre-frailty was observed in a cohort of older PLHIV attending care in Southern Ethiopia. Future research should focus on interventions targeting factors associated with frailty.

Providing differentiated service delivery to the ageing population of people living with HIV

Introduction

Differentiated service delivery (DSD) models for HIV are a person‐centred approach to providing services across the HIV care cascade; DSD has an increasing policy and implementation support in high‐burden HIV countries. The life‐course approach to DSD for HIV treatment has focused on earlier life phases, childhood and adolescence, families, and supporting sexual and reproductive health during childbearing years. Older adults, defined as those over the age of 50, represent a growing proportion of HIV treatment cohorts with approximately 20% of those supported by PEPFAR in this age band and have specific health needs that differ from younger populations. Despite this, DSD models have not been designed or implemented to address the health needs of older adults.

Discussion

Older adults living with HIV are more likely to have significant co‐morbid medical conditions. In addition to the commonly discussed co‐morbidities of hypertension and diabetes, they are at increased risk of cognitive impairment, frailty and mental health conditions. Age and HIV‐related cognitive impairment may necessitate the development of adapted educational materials. Identifying the optimal package of differentiated services to this population, including the frequency of clinical visits, types and location of services is important as is capacitating the healthcare cadres to adapt to these challenges. Technological advances, which have made remote monitoring of adherence and other aspects of disease management easier for younger populations, may not be as readily available or as familiar to older adults. To date, adaptations to service delivery have not been scaled and are limited to nascent programmes working to integrate treatment of common co‐morbidities.

Conclusions

Older individuals living with HIV may benefit from a DSD approach that adapts care to the specific challenges of ageing with HIV. Models could be developed and validated using outcome measures, such as viral suppression and treatment continuity. DSD models for older adults should consider their specific health needs, such as high rates of co‐morbidities. This may require educational materials, health worker capacity building and outreach designed specifically to treat this age group.

Frailty in people living with HIV: an update

PURPOSE OF REVIEW

The HIV population is ageing with rising rates of frailty though strategies of how best to manage it remain ill-defined. It also remains unclear what the prevalence of frailty is within this cohort, how best to diagnose it and what factors are associated.

RECENT FINDINGS

The prevalence of frailty remains unclear because of heterogenous results. Routine screening in those 50+ is recommended and whilst the Fried Frailty Phenotype is currently preferred the Clinical Frailty Scale could be considered. No biomarkers are currently recommended. Looking at associated factors, HIV neurocognitive impairment and long-term alcohol usage has been shown to be associated with developing frailty whilst those who are frail have been shown to be less active and more likely to fall. NAFLD with fibrosis has been shown to be an indicator of metabolic age and the Pooled Cohort Equations has been shown to be more effective in diagnosing cardiovascular risk in frail people living with HIV.

SUMMARY

Whilst the prevalence of frailty differs between countries, with the addition of prefrailty, this represents a large proportion of people living with HIV. Services must ensure strategies are in place to support those living with HIV and frailty. Further longitudinal studies are required.

Mental health and well-being of older adults living with HIV in sub-Saharan Africa: a systematic review

OBJECTIVE

In this systematic review, we aimed to summarise the empirical evidence on common mental disorders (CMDs), cognitive impairment, frailty and health-related quality of life (HRQoL) among people living with HIV aged ≥50 years (PLWH50 +) residing in sub-Saharan Africa (SSA). Specifically, we document the prevalence and correlates of these outcomes.

DESIGN, DATA SOURCES AND ELIGIBILITY CRITERIA

The following online databases were systematically searched: PubMed, CINAHL, PsycINFO, Embase and Scopus up to January 2021. English-language publications on depression, anxiety, cognitive function, frailty and quality of life among PLWH50+ residing in SSA were included.

DATA EXTRACTION AND SYNTHESIS

We extracted information, including study characteristics and main findings. These were tabulated, and a narrative synthesis approach was adopted, given the substantial heterogeneity among included studies.

RESULTS

A total of 50 studies from fifteen SSA countries met the inclusion criteria. About two-thirds of these studies emanated from Ethiopia, Uganda and South Africa. Studies regarding depression predominated (n=26), followed by cognitive impairment (n=13). Overall, PLWH50+ exhibited varying prevalence of depression (6%-59%), cognitive impairments (4%-61%) and frailty (3%-15%). The correlates of CMDs, cognitive impairment, frailty and HRQoL were rarely investigated, but those reported were sociodemographic variables, many of which were inconsistent.

CONCLUSIONS

This review documented an increasing number of published studies on HIV and ageing from SSA. However, the current evidence on the mental and well-being outcomes in PLWH50+ is inadequate to characterise the public health dimension of these impairments in SSA, because of heterogeneous findings, few well-designed studies and substantial methodological limitations in many of the available studies. Future work should have sufficiently large samples of PLWH50+, engage appropriate comparison groups, harmonise the measurement of these outcomes using a standardised methodology to generate more robust prevalence estimates and confirm predictors.

Food insecurity and frailty among women with and without HIV in the United States: a cross-sectional analysis

INTRODUCTION

Frailty is frequently observed among people with HIV, and food insecurity is associated with frailty in the general population. Evidence is scarce on the associations between food insecurity and frailty among women with HIV who may be particularly vulnerable to the impacts of food insecurity. The goal of this study was to assess associations between food insecurity and frailty among women with and without HIV.

METHODS

There were 1265 participants from the Women's Interagency HIV Study who participated in frailty assessments in 2017. Frailty was measured using the Fried Frailty Phenotype, and women were subsequently categorized as robust, pre-frail or frail. Food insecurity was assessed using the U.S. Household Food Security Survey Module, with women categorized as having high, marginal, low or very low food security. Multinomial logistic regression models were conducted to examine cross-sectional associations between food insecurity and frailty while adjusting for socio-demographic, behavioural and HIV status covariates.

RESULTS AND DISCUSSION

Approximately one-third (31.9%) of the women had marginal, low or very low food security, and the proportions of women who met the criteria for frailty or pre-frailty were 55.6% and 12.4% respectively. In the adjusted model, the relative risk ratio (RRR) of frailty for women with very low food security versus women with high food security was 3.37 (95% CI [1.38 to 8.24], p < 0.01); the corresponding RRR of pre-frailty was 3.63 (95% CI [1.76 to 7.51], p < 0.001). Higher annual household income was associated with lower RRRs of frailty or pre-frailty (p < 0.01). Similarly, older age was associated with more frequent frailty (RRR=1.06, 95% CI [1.03 to 1.09], p < 0.001). HIV serostatus was not significantly associated with either pre-frailty (RRR=0.97, 95% CI [0.71 to 1.31]) or frailty (RRR=0.75, 95% CI [0.48 to 1.16]).

CONCLUSIONS

Very low food security was associated with more frequent frailty and pre-frailty among women with and without for HIV. HIV serostatus was not associated with frailty.
