Depression and aging with HIV: Associations with health-related quality of life and positive psychological factors

Geographic Patterns of Human Immunodeficiency Virus (HIV) Risk Behaviors Among Older Adults: A Strategy for Identifying Space as a Risk Exposure

OBJECTIVES

This study examined geographical patterns of HIV risk among adults aged 60 and older.

METHODS

The 2019 Behavioral Risk Factor Surveillance System (BRFSS) weighted data was used to analyze self-reported participation in HIV risk behaviors among older adults (n = 62,852). Logistic regression models were used on a dichotomous HIV risk variable to map the distribution of HIV risk behaviors across both census regions and divisions.

RESULTS

The weighted model revealed significance across regions. Across all regions, identifying as female, identifying as Hispanic, and reporting not having depression were protective from participating in HIV risk behaviors.

DISCUSSION

The geographic heterogeneity in patterns of high-risk behaviors among older adults are discussed, along with the implications of partner access (marital status) and emotional health (depression) that need further examination. Recommendations for additional geographic analysis are made.

Sleep quality mediates the effect of medical social support on depression symptoms in patients with HIV/AIDS

OBJECTIVES

The purpose of our study is to further understanding of the depression symptoms of HIV/AIDS patients in Guilin, Guangxi via exploring whether there is a mediating effect of sleep quality on medical-social support and depression symptoms and therefore provide a theoretical basis for application of medical-social support to alleviate depression symptoms of HIV/AIDS patients.

METHODS

A convenience sampling method was used to select 200 HIV/AIDS patients for the study. Depression symptoms, sleep quality, and medical-social support of the study participants were investigated using The Center for Epidemiological Studies Depression Scale (CES-D), The Pittsburg Sleep Quality Index (PSQI), and The Medical Outcomes Study Social Support Survey (MOS-SSS), respectively. Predictors of depression symptoms were explored by multiple linear regression, and Pearson correlation was used to analyze the relationship between sleep quality, medical-social support, and depression symptoms. Mediating effect analysis was performed by nonparametric Bootstrap test.

RESULTS

In this study, the incidence of depression symptoms was 54.4%. Multiple linear regression analysis showed that leanness (β = 0.161, P = 0.008), obesity (β = 0.186, P = 0.002), sleep quality score > 7 (β = 0.331, P < 0.001), and medical-social support score > 56 (β = -0.247, P < 0.001) could influence depression symptoms of HIV and Pearson's correlation analysis demonstrated that there was a two-way correlation between sleep quality, medical social support and depression symptoms (P < 0.05). In addition, Bootstrap tests showed that medical-social support might affect depression symptoms not only directly but also indirectly through the mediating effect of sleep quality with the direct and mediating effects accounting for 77.25% and 22.75% of the total effect, respectively.

CONCLUSION

The prevalence of depression symptoms is high among HIV/AIDS patients in Guilin City. The depressive symptoms of PLWHs(people living with HIV) are related to their sleep quality and medical-social support, and sleep quality partially mediates the relationship between medical-social support and depression symptoms. Therefore, interventions to improve sleep quality and medical-social support have the potential to allay the depression symptoms of HIV/AIDS patients.

Implications of vascular depression for successful cognitive aging in HIV Disease

Although older adults with HIV are at high risk for mild neurocognitive disorders, a subset experience successful cognitive aging (SCA). HIV is associated with an increased risk of vascular depression (VasDep), which can affect cognitive and daily functioning. The current study examined whether VasDep impedes SCA among older adults with HIV. 136 persons with HIV aged 50 years and older were classified as either SCA+ (n = 37) or SCA- (n = 99) based on a battery of demographically adjusted neurocognitive tests and self-reported cognitive symptoms. Participants were also stratified on the presence of vascular disease (e.g., hypertension) and current depression as determined by the Composite International Diagnostic Interview and the Depression/Dejection scale of the Profile of Mood States. A Cochran-Armitage test revealed a significant additive effect of vascular disease and depression on SCA in this sample of older adults with HIV (z = 4.13, p <.0001). Individuals with VasDep had the lowest frequency of SCA+ (0%), which differed significantly from the group with only vascular disease (30%, OR = 0.04, CI = 0.002,0.68)) and the group with neither vascular disease nor depression (47% OR = 0.02, CI = 0.33,0.001). Findings were not confounded by demographics, HIV disease severity, or other psychiatric and medical factors (ps > 0.05). These data suggest that presence of VasDep may be a barrier to SCA in older adults with HIV disease. Prospective, longitudinal studies with neuroimaging-based operationalizations of VasDep are needed to further clarify this risk factor's role in the maintenance of cognitive and brain health in persons with HIV disease.

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.

Depressive Symptoms, the Impact on ART Continuation, and Factors Associated with Symptom Improvement Among a Cohort of People Living with HIV in British Columbia, Canada

Depressive symptoms among people living with HIV (PLWH) are associated with poorer overall health outcomes. We characterized depressive symptoms and improvements in symptomology among PLWH (≥ 19 years old) in British Columbia (BC), Canada. We also examined associations between depressive symptomology and antiretroviral therapy (ART) treatment interruptions. Depressive symptoms were measured using the 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10), within a longitudinal cohort study with three surveys administered 18-months apart. We used multivariable logistic regression to model factors associated with improvements in depressive symptoms (CES-D-10 scores from ≥ 10 to < 10). Of the 566 participants eligible for analysis 273 (48.2%) had CES-D scores indicating significant depressive symptoms (score ≥ 10) at enrollment. Improvements in symptoms at first follow-up were associated with greater HIV self-care on the Continuity of Care Scale (adjusted odds ratio: 1.17; 95% CI 1.03-1.32), and not having a previously reported mental health disorder diagnosis (aOR 2.86; 95% CI 1.01-8.13). Those reporting current cocaine use (aOR 0.33; 95% CI 0.12-0.91) and having a high school education, vs. less than, (aOR 0.25; 95% CI 0.08-0.82) had lower odds of improvement in depressive symptomatology. CES-D scores ≥ 10 were not significantly associated with ART treatment interruptions during follow-up (aOR: 1.08; 95% CI:0.65-1.8). Supporting greater self-care and consideration of mental health management strategies in relation to HIV may be useful in promoting the wellbeing of PLWH who experience depressive symptoms.

Prevalence of depression among people living with HIV in rural hospitals in South-Western Nigeria-Association with clinico-demographic factors

Major depression is the most common neuropsychiatric disorder among people living with HIV (PLWH) and is predictive of high morbidity and mortality among them. This study estimated the prevalence and explored factors associated with depression among PLWH in two rural secondary health facilities providing anti-retroviral therapy (ART) services in Southwestern Nigeria between September and December 2020. The Patient Health Questionnaire-9 (PHQ-9) was used to screen and identify PLWH aged 18 years or older with depression. Descriptive statistics, bivariate and multivariate analyses were performed with SPSS version 23. A total of 172 respondents were screened. The prevalence of depression was 16.3% (95% CI 11.1%, 22.7%). Mild, moderate, and moderately severe depression was identified in 17 (9.9%), 8(4.7%) and 3(1.7%) of the participants, respectively. One (0.6%) respondent had suicidal ideation. Of PLWH with any depression, 20/28(71.4%) were within the 40-59 years of age range. None of the participants was on antidepressants. The factor most associated with depression was hypertension, with adjusted odd ratios of 9.8(95% CI 3.5-27.3, p < 0.0001). The study highlights the importance of screening for the severity of depression among PLWH in rural hospitals providing ART services in Africa. PLWH with comorbid hypertension were more likely to suffer from some form of depression.

Waitlist-controlled trial of an online intervention to address mental health among older people living with HIV

Background: Older people living with HIV (PLWH) often experience elevated levels of depression, anxiety, and loneliness.Methods: This waitlist-controlled trial examined the effectiveness of online audio mindfulness lessons in impacting these feelings among older PLWH.Results: Among 214 participants, the mean (SD) age was 60.4 (5.9) years, 89% were male, and 69% were white. After 25 days, the intervention group showed significant improvements versus the waitlist control group in symptoms of depression (20.3% improvement, p < .01) and symptoms of anxiety (22.4% improvement, p = .03), but not in loneliness as measured by a Daily Diary (12.9% improvement, p = .07) or the 3-Item Loneliness Scale (4.8% improvement, p = .27). Secondary analyses among participants with elevated baseline symptoms of depression showed a 26.3% improvement (p < .01), with a moderate effect size (Hedge's g = 0.69). Similarly, those with elevated baseline symptoms of anxiety showed a 25.6% improvement (p < .01), a moderate effect size (g = 0.54), while those with moderate or severely elevated loneliness showed an 18.9% improvement in daily loneliness (p < .01), a moderate effect size (g = 0.55).Conclusion: This waitlist-controlled trial is the first to show that a series of brief, online audio mindfulness lessons improves mental health outcomes among older PLWH. For many patients, this intervention may offer relief that is both accessible and affordable.

Psychological grit moderates the relation between lifetime stressor exposure and functional outcomes among HIV-seropositive and HIV-seronegative adults

The ability to maintain functional independence throughout the lifespan may be diminished among medically compromised and chronically stressed populations. People living with HIV are more likely to demonstrate functional impairment and report greater exposure to lifetime and chronic stressors than their seronegative counterparts. It is well-known that exposure to stressors and adversity is associated with functional impairment outcomes. However, to our knowledge, no studies have examined how protective factors such as psychological grit mitigate the negative effects of lifetime and chronic stressor exposure on functional impairment, and how this association differs by HIV-status. To address this issue, we studied associations between lifetime and chronic stressor exposure, grit, and functional impairment in 176 African American and non-Hispanic White HIV-seropositive (n = 100) and HIV-seronegative (n = 76) adults, aged 24-85 (M = 57.28, SD = 9.02). As hypothesised, HIV-seropositive status and lower grit, but not lifetime stressor exposure, were independently associated with more functional impairment. Moreover, there was a significant three-way interaction between HIV-status, grit, and lifetime stressor exposure, b = 0.07, p = 0.025, 95% CI [0.009, 0.135]. Specifically, lifetime stressor exposure was related to more functional impairment for HIV-seronegative-but not HIV-seropositive-adults who reported low levels of grit. These findings suggest that the protective effects of grit may differ across populations at risk for functional impairment.

Longitudinal Associations of Psychiatric Risk Factors with Non-psychiatric Hospitalization in a Large Cohort of People Living with HIV in New York City

Hospitalizations among people living with HIV (PLWH) are frequent and costly. This study examined the association between psychiatric, HIV-related, and demographic factors and hospitalization rates among PLWH using data from the Einstein-Rockefeller-City University of New York Center for AIDS Research Clinical Cohort Database. Of the 10,215 PLWH included in the sample, 45% had at least one non-psychiatric hospitalization between 2009 and 2018, with significant risk factors including prior psychiatric outpatient visits, depression, or alcohol-related disorder diagnoses, female sex, older age, CD4 count < 500 cells/uL, and detectable viral load. Additionally, 14% had an HIV-related hospitalization, with significant risk factors including prior psychiatric outpatient visits, alcohol- and substance-related disorder diagnoses, female sex, older age, CD4 count < 500 cells/uL, and detectable viral load. The study emphasizes the need for tailored interventions, including integrated treatment and comprehensive case management, for PLWH with comorbid psychiatric disorders, women, and older adults.

Number of Sexual Partners and Patient-Reported Outcomes Among Men Age 50+ with HIV

Many men age 50+ with HIV (MWH age 50+) are sexually active. However, little is known about the relationship between the number of sexual partners and patient-reported outcomes in this population. To help address this need, analyses were performed on data from the Aging with Dignity, Health, Optimism and Community cohort, an observational study of adults age 50+ with HIV. Of 876 MWH age 50+, 26.8% had 0 sexual partners in the past year, 27.9% had 1, 21.5% had 2-5, and 23.9% had >5. Men with one partner were significantly less lonely and less depressed than any other group (p < .01 for pairwise comparisons). Men with zero partners were more depressed than any other group. Linear regression controlling for race and relationship status showed men with one partner had lower levels of loneliness than any other group. They also had lower levels of depression than men with zero or more than than five sexual partners, although depression levels were not significantly different for men with one or with two to five partners. Linear regression also showed that men in relationships were less lonely and less depressed than men who were not in relationships, after controlling for race and number of sexual partners. Better understanding of the roles that number of sex partners and relationships play in the mental health of MWH age 50+ may help ameliorate the burden of loneliness and depression in this vulnerable population.

Implications of Vascular Depression for Successful Cognitive Aging in HIV disease

Introduction

Although older adults with HIV are at high risk for mild neurocognitive disorders, a subset experience successful cognitive aging (SCA). HIV is associated with an increased risk of vascular depression (VasDep), which can affect cognitive and daily functioning. The current study examined whether VasDep impedes SCA among older adults with HIV.

Methods

136 persons with HIV aged 50 years and older were classified as either SCA+ (n=37) or SCA- (n=99) based on a battery of demographically adjusted neurocognitive tests and self-reported cognitive symptoms. Participants were also stratified on the presence of vascular disease (e.g., hypertension) and current depression as determined by the Composite International Diagnostic Interview and the Depression/Dejection scale of the Profile of Mood States.

Results

A Cochran-Armitage test revealed a significant additive effect of vascular disease and depression on SCA in this sample of older adults with HIV (z=4.13, p<.0001). Individuals with VasDep had the lowest frequency of SCA+ (0%), which differed significantly from the group with only vascular disease (30%, OR=0.04, CI=0.002,0.68)) and the group with neither vascular disease nor depression (47% OR =0.02, CI=0.33,0.001). Findings were not confounded by demographics, HIV disease severity, or other psychiatric and medical factors (ps>.05).

Discussion

These data suggest that presence of VasDep may be a barrier to SCA in older adults with HIV disease. Prospective, longitudinal studies with neuroimaging-based operationalizations of VasDep are needed to further clarify this risk factor's role in the maintenance of cognitive and brain health in persons with HIV disease.

Association Between VACS Index and Health-Related Quality of Life in Persons with HIV: Moderating Role of Fruit and Vegetable Consumption

BACKGROUND

The health status of people with HIV (PWH) influences their health-related quality of life (HRQOL). Modifiable lifestyle factors may improve HRQOL. This study (1) explores the association between modifiable lifestyle factors (physical activity and nutrition) and HRQOL and (2) examines if these lifestyle factors moderate the association health status and HRQOL.

METHODS

Participants included 91 community dwelling PWH (age 36-65 years) from the university lab. Participants reported mental and physical HRQOL via the Medical Outcome Study 36-Item Short-Form (SF-36). Physical activity was examined via the International Physical Activity Questionnaire and nutrition (i.e., fruit and vegetable consumption) was assessed with the By-Meal Screener. Health status was ascertained via the Veterans Aging Cohort Study (VACS) Index.

RESULTS

Aim 1 analyses indicated that neither physical activity nor nutrition was related to mental HRQOL (p's > .05). However, greater physical activity (β = .33, p < .01) and nutrition (β = .23, p = .03) were each independently related to better physical HRQOL and remained significant after accounting for co-occurring medical conditions. For aim 2, the interaction between health status and nutrition was statistically significant (β = .24, p = .02), such that the association between worse health status and worse physical HRQOL was weaker with better nutrition. There was not a statistically significant interaction between physical activity and health status on physical HRQOL (p > .05).

CONCLUSION

Physical HRQOL is related to self-reported physical activity and nutrition, with nutrition showing a moderating effect on the association between health status and physical HRQOL. Thus, future interventional studies designed to improve physical HRQOL should target both physical activity and nutrition.

Analysis of Factors Influencing Depression in Elderly People Living with HIV/AIDS Based on Structural Equation Model: A Cross-Sectional Study in Guangxi, China

Purpose

The purpose of our study is to understand the current status of depression and medical social support in elderly HIV/AIDS, as well as the role of social support on depression, so as to provide a certain reference for reducing the occurrence of depression in the population.

Methods

A total of 115 participants with PLWHA (people living with HIV/AIDS) aged 50 years or older were collected in Guilin from December 2021 to July 2022. Depression and medical social support were assessed using the Center for Streaming Depression Scale (CES-D) and the Medical Social Support Scale (MOS-SSS). The structural equation model was used to examine the relationship between medical social support and depression.

Results

Sixty-one of 115 participants developed depressive symptoms with a prevalence of 53.0%. The results of univariate analysis showed that ethnicity, health status, mean monthly income, antiviral treatment status, and medical social support influenced PLWHA depression (P<0.05). Simple linear regression showed that health status (95% CI: -9.901~-2.635), and antiviral treatment status (95% CI: -12.969~-3.394) influent depression (P<0.05). There were associations between total medical social support, practical support dimension, message and emotional support dimension, social interactive cooperation dimension, emotional support dimension and depression (unadjusted and adjusted for contextual factors) (P < 0.05). Using multiple linear regression analyses, we found that medical-social support was negatively associated with depression with a standardized effect value of -0.223. PLWHA with higher medical social support had lower prevalence of depression.

Conclusion

The results indicate that the prevalence of depression among HIV/AIDS patients in Guilin is high. So the joint efforts of individuals, families, and society are needed to improve the physical and mental health of the PLWHA.

The impact of life stress, psychological resources, and proactive behaviors on quality of life among people living with HIV

OBJECTIVES

Quality of life (QoL) is an important consideration for people living with HIV (PWH). We investigated the relationship between stress, psychological resources, and proactive behaviors, on QoL (conceptualized as life satisfaction, successful aging, and depressive symptoms) by testing the hypotheses: (1) greater life stress (stress and functional impairment) is associated with poorer QoL; (2) resources (mastery, resilience, and social support) are associated with better QoL, beyond the influence of stress; and (3) proactive behaviors (medication management and leisure activities) mediate the relationship between resources and QoL.

METHODS

Secondary analyses were performed (N = 128 PWH). Participants' mean age was 52.3, 83.6% were male, and 53.9 identified as white. Multivariate regressions were performed within the context of path analyses.

RESULTS

In series 1, greater stress was associated with poorer life satisfaction (p < 0.001), lower self-rated successful aging (p < 0.001), and greater depression (p < 0.001). Functional impairment was associated with lower successful aging (p = 0.017) and greater depression (p = 0.001). In series 2, which accounted for mastery, resilience, social support, as well as demographic covariates, mastery was associated with greater life satisfaction (p = 0.038). In series 3, stress, functional impairment, leisure activities, and ART management were added to the model and social support was associated with engagement in leisure activities (p < 0.001), which was associated with better successful aging (p = 0.006). Fit indices suggested adequate relative fit. In bootstrapped analyses of indirect effects, social support was indirectly associated with successful aging through leisure activities (p = 0.020).

CONCLUSIONS

QoL, as captured by self-rated successful aging, is threatened by stress but positively influenced by social support and engaging in leisure activities. Findings support a model of proactive successful aging for PWH.

Social Support, Internalized HIV Stigma, Resilience and Depression Among People Living with HIV: A Moderated Mediation Analysis

Internalized HIV stigma has been associated with depression among people living with HIV (PLWH). However, it is still unclear whether resilience would mediate the association between internalized HIV stigma and depression and how this indirect effect would be moderated by social support. Data were collected from 402 PLWH in South Carolina using a cross-sectional survey. Data were fitted using a path model that specified the extent to which internalized HIV stigma and depression were related through resilience and how this effect was moderated by social support. Sociodemographic characteristics were included in the model as covariates. The indirect effect of internalized HIV stigma on depression through resilience was statistically significant for high social support but not for low social support. To mitigate negative impacts of internalized HIV stigma on mental health of PLWH, intervention efforts should integrate multilevel components for promoting both resilience and social support.

Elevated frequency and everyday functioning implications of vascular depression in persons with HIV disease

Depression and cardiovascular disease are common and associated with one another in HIV disease. This study aimed to determine the frequency and everyday functioning implications of the clinical syndrome of vascular depression among people living with HIV (PLWH). Participants in this cross-sectional study included 536 PLWH and 272 seronegative individuals who completed a biomedical and psychiatric research evaluation. Vascular depression was operationalized as the current presence of: 1) two or more vascular conditions; and 2) depression as determined by a normative elevation on the Depression/Dejection subscale of the Profile of Mood States or a diagnosis of Major Depressive Disorder per the Composite International Diagnostic Interview. Everyday functioning was measured by both self- and clinician-rated activities of daily living. A logistic regression model showed that HIV was associated with a three-fold increased risk of vascular depression, independent of potential confounding factors. A second logistic regression model within the PLWH sample showed that PLWH with vascular depression had significantly greater odds of dependence in everyday functioning as compared to PLWH with either vascular disease or depression alone. The elevated frequency of vascular depression in PLWH is consistent with the vascular depression hypothesis from the late-life depression literature. The high rate of functional dependence among PLWH with vascular depression highlights the clinical importance of prospective work on this syndrome in the context of HIV disease.

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.

Mapping frailty in people living with HIV: A nationwide study in Greece

OBJECTIVES

Frailty is known to affect people living with HIV prematurely, compared to the ageing seronegative population. In this cross-sectional study, we aimed to assess frailty prevalence in people living with HIV in Greece and find associations of frailty criteria with clinical data.

METHODS

Demographic and clinical data were collected from 477 participants in six HIV clinics. Fried's frailty phenotype was used to assess frailty prevalence, and participants were classified as frail, pre-frail or robust. Associations of several factors with overall frailty phenotype, as well as with frailty criteria, were explored.

RESULTS

The median age was 43 years old (IQR = 51.5) and 444/477 (93%) were men. Most of the participants (429/477, 93.5%) had an undetectable HIV viral load, and a CD4 cell count over 500 cells/μl (366/477, 76.7%). Frailty assessment classified 285/477 (62.1%) as robust, 155/477 (33.8%) as pre-frail and 19/477 (4.1%) as frail. Weakness in grip strength was the most prevalent criterion (128/477, 26.8%), followed by exhaustion (46/477, 9.6%). Lower CD4 cell count, history of AIDS diagnosis, CNS disorders, psychiatric diagnoses, and polypharmacy were strongly associated with frailty.

CONCLUSIONS

Although the prevalence of frailty in people living with HIV in Greece is uncommon, when combined with pre-frailty over a third of people are affected, which requires attention in clinical practice. The physical and psychological aspects of frailty highlight the need for a holistic approach to prevent or counteract it. The diverse associations of frailty criteria with HIV-related and non-HIV-related factors suggest a possible variation in people's different healthcare needs.

Four-Year Trajectories of Internal Strengths and Socioemotional Support Among Middle-Aged and Older Adults with HIV

Positive psychological attributes are associated with better health outcomes, yet few studies have identified their underlying constructs and none have examined their temporal trajectories in clinical vs. non-clinical samples. From data collected over 4 years from people with HIV (PWH) and HIV-uninfected (HIV-) participants, we identified two latent factors (internal strengths; socioemotional support) based on responses to seven positive psychological attributes. Internal strengths increased over 4 years for PWH, but not for HIV- comparisons. Socioemotional support did not change significantly in either group. Lower internal strengths and worse socioemotional support were related to greater depressive symptoms. We speculate that improvement in internal strengths in PWH could reflect their being in care, but this requires further study to include PWH not in care. Given the apparent malleability of internal strengths and their association with improved health outcomes, these attributes can serve as promising intervention targets for PWH.

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.

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.

Sexual Dysfunctions Among People Living With HIV With Long-Term Treatment With Antiretroviral Therapy

Introduction

Sexuality plays an essential role in the psychosocial well-being of people living with HIV (PLHIV) but it is still less assessed by healthcare professionals during treatment.

Aim

To investigate the frequency of those screening positive for sexual dysfunction (SD) and associated factors according to gender/sexual orientation in PLHIV under long-term treatment with antiretroviral therapy (ART).

Methods

Between September 2013 and October 2016, 234 PLHIV adults in treatment in São Paulo were included. Participants were sexually active, did not present sexual orientation disorder or body dysmorphic disorder, and did not use sexual hormones. We performed clinical interviews and measured levels of depression, anxiety, and levels of sexual hormones. SD was assessed using a self-report questionnaire.

Main Outcome Measures

Proportion of participants screening positive for SD in the International Index of Erectile Function, the Index of Premature Ejaculation, and the Female Sexual Function Index. In the regression analyses, the outcome SD considered any SD presented with disregard to gender.

Results

70% of participants reported consistent adherence to ART and 96% had an undetectable viral load. The median (Md) duration of ART was 198 months (inter quartil range, IQR 111.6–230.4) and the median CD4 was 655 cells/mm³ (IQR 443–871). Screening positive for erectile dysfunction was 49.7%, premature ejaculation 16.9%, female sexual dysfunction 27.4% and hypoactive desire 45.1%. Lower testosterone and prolactin levels were associated with erectile dysfunction in heterosexual men (n = 58); lower levels of oestradiol and higher levels of follicle stimulating hormone were associated with female sexual dysfunction and hypoactive desire in female participants (n = 63). The multivariable model used included comorbidities and hormonal abnormality and found that age (odds ratio, OR = 1.04, 95% confidence interval, 95%CI 1.00–1.08, P = .026) and the presence of depression/anxiety (OR = 2.96; 95%CI 1.52–5.77; P = .001) were associated with SD. Also, men reporting engaging in sex with other men were associated with screening positive for SD (OR 2.66; 95%CI 1.52–5.77, P = .013).

During treatment of PLHIV, it is important to evaluate sexual health and symptoms of depression and anxiety specifically.

The strength of this study consists in evaluating PLHIV who have been in long-term treatment with ART and analyzing those screening positive for SD and associated factors for each group (heterosexual men, men reporting engaging in sex with other men, and women). Limitation includes the difficulty to generalize the findings of the study, and not exploring women's sexual orientation.

Conclusion

PLHIV in long-term treatment with ART presented alarming rates of depression/anxiety which in turn is correlated with sexual and physical health problems.

Factors Associated with Resilience Among Older People Living with HIV

Resilience, a measure of stress coping ability, may be important in helping older people (age 50+) living with HIV (PLWH) age successfully, but limited data exist regarding factors that contribute to resilience for this group. This study uses the Connor-Davidson Resilience Scale 2 (CD-RISC2) to assess resilience, based on a cross-sectional analysis of 1047 older PLWH. Bivariate linear regression models were used to identify predictor variables that had a relationship with resilience. Those variables were then included in a multivariable linear regression model, which was pared using backward selection. In the multivariable model, higher income and greater interpersonal support were associated with greater resilience, whereas depression and anxiety were associated with lower resilience. Relevant interventions that address these issues, such as increasing opportunities for social support and increasing screening for and treatment of depression and anxiety, are identified as potential pathways to increase resilience among older PLWH.

Different profiles among older adults with HIV according to their chronological age and the year of HIV diagnosis: The FUNCFRAIL cohort study (GeSIDA 9817)

Background

People in their fifties with HIV are considered older adults, but they appear not to be a homogeneous group.

Objective

To evaluate the differences among older adults with HIV according to their chronological age and the year of HIV diagnosis.

Methods

Cross-sectional study of the FUNCFRAIL cohort. Patients 50 or over with HIV were included and were stratified by both chronological age and the year of HIV diagnosis: before 1996 (long-term HIV survivors [LTHS]) and after 1996. We recorded sociodemographic data, HIV-related factors, comorbidities, frailty, physical function, other geriatric syndromes, and quality of life (QOL).

Results

We evaluated 801 patients. Of these, 24.7% were women, 47.0% were LTHS, and 14.7% were 65 or over. Of the 65 or over patients, 73% were diagnosed after 1996. Higher rates of comorbidities among LTHS were found, being the more prevalent: COPD, history of cancer, osteoarthritis, depression, and other psychiatric disorders while the more prevalent among the 65 or over patients were: hypertension, diabetes, dyslipidemia, cancer, and osteoarthritis. LTHS showed a significantly worse QOL. There were no differences by the year of HIV diagnosis regarding frailty and functional impairment (SPPB <10) but they were more than twice as prevalent in the 65 or over patients compared to the other chronological age groups.

Conclusions

A LTHS and a 65 or over person are both “older adults with HIV,” but their characteristics and requirements differ markedly. It is mandatory to design specific approaches focused on the real needs of the different profiles.

Relationship of the balloon analog risk task to neurocognitive impairment differs by HIV serostatus and history of major depressive disorder

HIV and major depressive disorder (MDD) commonly co-occur and are both linked to greater risk-taking behavior, possibly due to neurocognitive impairment (NCI). The present study examined the concordance of the Balloon Analog Risk Task (BART), a gold standard measure of risk-taking propensity, with NCI and real-world sexual risk behaviors in PWH with comorbid MDD. Participants included 259 adults, stratified by HIV serostatus (HIV + /HIV −) and lifetime MDD (MDD + /MDD −), who completed neuropsychological testing, the BART, and sexual risk behavior questionnaires. Logistic regression, stratified by HIV serostatus, examined joint effects of MDD and BART (linear and quadratic) on NCI. Follow-up linear regressions examined sexual risk behavior and neurocognitive domain T-scores as correlates of the BART. NCI prevalence was lowest in HIV − /MDD − , but BART scores did not differ by HIV/MDD status. In the HIV + group, BART performance predicted NCI such that high and low BART scores related to greater odds of NCI, but only in dual-risk HIV + /MDD + individuals. HIV + /MDD + individuals with both low and high BART scores exhibited poorer learning and recall, whereas processing speed and executive function were only poor in low BART risk-taking HIV + /MDD + . Higher BART scores linearly related to higher sexual risk behaviors only in MDD + individuals, independent of HIV serostatus. Low and high risk-taking on the BART may reflect discrete neurocognitive profiles in HIV + /MDD + individuals, with differential implications for real-world sexual risk behavior. HIV and comorbid MDD may disturb corticostriatal circuits responsible for integrating affective and neurocognitive components of decision-making, thereby contributing to risk-averse and risk-taking phenotypes.

A Cross-Sectional Study to Evaluate the Effects of Age and Duration of HIV Infection on Anxiety and Depression in Cisgender Men

This observational cross-sectional study of 152 people with HIV (PWH) examined the effects of age and estimated duration of HIV infection (EDI) on depressive and anxiety symptoms. All participants were cisgender men and completed the Profile of Moods State (POMS), a self-report inventory of current (i.e., past week) mood states. Overall, study results confirmed higher levels of anxiety and depression in PWH compared to individuals without HIV. Age group (< 50 or ≥ 50 years) moderated the effect of EDI (< 3 or ≥ 3 years) on mood disturbance. Specifically, younger PWH with early diagnosed infection exhibited the highest levels of depression and anxiety, whereas depression and anxiety were attenuated in older PWH with early infection such that their POMS scores did not significantly differ from the HIV-negative and chronically HIV-infected groups. Despite the small sample size and other important limitations in our study design, our preliminary findings confirm previous observations that older people may have some adaptive ability to better handle the acute psychological stressors associated with recent HIV infection.

Global Systematic Review of Common Mental Health Disorders in Adults Living with HIV

PURPOSE OF THE REVIEW

By reviewing the most recent common mental health disorders (CMHD) studies in people living with HIV (PLWH) (2018-2020), this review discusses the prevalence of CMHD, factors associated with CMHD in PLWH, mental health in PLWH from vulnerable groups, the impact of CMHD on HIV disease progression and adherence to antiretroviral therapy and the efficacy of different treatment approaches.

RECENT FINDINGS

After screening for eligibility 142 studies were included in the final systematic review. Only 27% of studies were conducted in Sub-Saharan Africa, which carries the highest burn of HIV disease globally. Despite the well-established increased risk of CMHD in PLWH, the current prevalence remains high, with studies reporting 28%-62% of PLWH having mental health symptoms.

CONCLUSION

Despite the significant challenges that CMHDs present to successful HIV treatment, there are many mental health treatments and interventions which can improve outcomes in PLWH and opportunities to task-shift and integrate mental health care with HIV care.

How Much Does HIV Positivity Affect the Presence of Oral HPV? A Molecular Epidemiology Survey

HIV-positive people showed a high oral prevalence of HPV-DNA and have a greater incidence of head and neck carcinomas compared to general population. We performed a molecular survey evaluating the presence of HPV-DNA in saliva of HIV-positive and HIV-negative subjects in order to quantify the risk represented by HIV-positivity. The sample was made up by 102 subjects: 40 HIV-positive, 32 HIV-negative with sexual risk behaviors (SRB) and 30 HIV-negative without risk factors. DNA was extracted from cellular pellets and HPV detection and genotyping were performed by PCR assays. In the HIV-positive group (of which 58.3% declared SRB) 33.33% of the sample were HPV-positive (33.33% to high-risk genotypes, 25.0% to low-risk genotypes and 41.66% to other genotypes). In the HIV-negative SRB group, HPV-positive subjects were 37.04% (60.0% to high risk genotypes, 20.0% to low risk genotypes, and 20.0% to other genotypes). Finally, in the control group, the HPV-positive subjects were 7.14% (50% to high-risk genotypes and 50% to low-risk genotypes). In the HIV group, concerning the HPV positivity, there was no significant difference between subjects with and without SRBs. In summary, we found a high oral HPV-DNA detection in HIV+ group, showing a strong relationship between HIV and HPV.

Depression is associated with hippocampal volume loss in adults with HIV

Depressive symptoms are more prevalent in persons with HIV (PWH) than HIV-uninfected individuals. In HIV-uninfected individuals, depression has been associated with atrophy in the hippocampus and other brain regions. In the present study, we investigated the impact of depression on brain structure in PWH. One hundred PWH participated in a cross-sectional study (56.6 ± 6.4 yrs, range 41-70 yrs, 24 females, 63 African Americans). The Beck's Depression Inventory-II (BDI-II) was used to assess depressive symptoms. Structural MRI images were collected. Both the voxel-based morphometry (VBM) technique and a region of interest (ROI) based approach were used to examine the relationship between hippocampal gray matter volume (GMv) and depressive symptoms. The impact of HIV CD4 nadir and antidepressants was also investigated. Both VBM and ROI approaches revealed that higher BDI-II scores (implicating more severe depressive symptoms) were associated with loss of hippocampal GMv, especially in the right hippocampus and the right entorhinal cortex. Low CD4 nadir predicted additional hippocampal volume loss independent of depressive symptoms. Taking antidepressants did not have a detectable effect on hippocampal volume. In summary, having more depressive symptoms is associated with smaller hippocampal volume in PWH, and a history of severe immunosuppression (i.e., low CD4 nadir) correlates with additional hippocampal volume reduction. However, the impact of depression on hippocampal volume may be independent of HIV-disease severity such as low CD4 nadir.

Assessing psychological symptom networks related to HIV-positive duration among people living with HIV: a network analysis

This study aims to explore and visualize relationships among multiple psychological symptoms among people living with HIV (PLWH) with different HIV-positive durations and to compare centrality indices and densities of psychological symptom networks. We used subsets of data collected from five designated HIV/AIDS hospitals in China. Networks were constructed among 16 psychological symptoms. Centrality properties, including strength and closeness, were adopted to describe relationships among symptoms. The results showed that PLWH with longer HIV-positive durations had denser emotional networks, which indicated that they had more emotional neuroticism than their newly diagnosed counterparts. Sadness, self-abasement, and self-loathing were the most central psychological symptoms across different HIV-positive durations. Our study suggests the need to provide psychosocial support services targeting PLWH according to changing symptom severity and neuroticism trajectories. Interventions should focus on increasing empathy for PLWH and enhancing the ability to consider the situation from different perspectives to avoid the development of neuroticism in long-term survivors.

Chronically elevated depressive symptoms interact with acute increases in inflammation to predict worse neurocognition among people with HIV

We examined the joint effects of depressive symptoms (Beck Depression Inventory-II (BDI-II)) and systemic inflammation (plasma C-reactive protein (CRP)) on longitudinal profiles of neurocognition in a cohort of 143 people with HIV (PWH) on antiretroviral therapy. Global neurocognition, processing speed, motor skills, and attention/working memory all worsened as CRP increased but only among PWH who, on average, exhibited moderate to severe depressive symptoms (BDI-II > 22). Findings suggest that some PWH with chronically elevated depressive symptoms may have an inflammatory subtype of depression and a particular vulnerability to neurocognitive changes that may respond to drugs targeting inflammation or its neural sequelae.

HIV and three dimensions of Wisdom: Association with cognitive function and physical and mental well-being: For: Psychiatry Research

Wisdom is a unique human personality trait with cognitive, affective or compassionate, and reflective dimensions. We evaluated relationships of three specific dimensions of wisdom with cognitive function and physical and mental well-being in people with HIV (PWH) and HIV-negative (HIV-) participants. Subjects included 138 adults (61 PWH, 77 HIV-) from the San Diego community. Validated measures were used to assess wisdom and well-being. Cognitive function was assessed via the Montreal Cognitive Assessment. We conducted multivariate linear regressions to evaluate the associations of wisdom dimensions with cognitive function and physical and mental well-being. Compared to the HIV- group, PWH had lower mean scores on cognitive function, and physical and mental well-being, and cognitive and reflective dimensions of wisdom, but similar scores on affective or compassionate wisdom. Among PWH, higher total wisdom scores were associated with older age, lower likelihood of substance dependence, greater mental well-being, better cognitive function, higher resilience, social support, and optimism scores, as well as lower levels of perceived stress and nadir CD4 count. Our findings of an association of different dimensions of wisdom with physical and/or mental well-being in PWH would point to a possibility that enhancing these dimensions of wisdom might improve health outcomes in PWH.

Brain-derived neurotrophic factor (BDNF) is associated with depressive symptoms in older adults with HIV disease

Symptoms of depression are common among persons with HIV (PWH) and can have a significant impact on socioeconomic and personal well-being, but little is known about their neurobiological substrates in the context of HIV disease. This study examined the possible role of brain-derived neurotrophic factor (BDNF) in symptoms of depression and other aspects of mood in 109 PWH and 43 seronegative participants aged 50 and older. Participants completed the Profile of Mood States (POMS) which measured six dimensions of mood and was normatively adjusted for sex. A model controlling for medical comorbidities and substance use diagnoses among PWH showed a significant interaction between BDNF and POMS subscales. Planned post hoc analyses revealed that lower BDNF was only associated with higher scores on Depression-Dejection and Confusion-Bewilderment POMS subscales among PWH and at small-to-medium effect sizes. Lower levels of BDNF were associated with AIDS diagnoses and CD4 count, but not with viremia or duration of infection. BDNF levels did not differ between the PWH and HIV - samples, and there were no significant correlations between BDNF and any POMS variable in the HIV - group. Findings implicate BDNF in the neuropathophysiology of specific depressive symptoms in the context of HIV disease. Future studies may examine whether BDNF levels change over time, are sensitive to other aspects of mood disorders in HIV, and are associated with markers of HIV-associated neural injury.

Lower CSF homovanillic acid relates to higher burden of neuroinflammation and depression in people with HIV disease

BACKGROUND

HIV-related neuroinflammation has been proposed as a catalyst for dopaminergic dysregulation in mesocortical pathways, which may contribute to the pathogenesis of depression. Abnormalities in dopaminergic neurotransmission and depression are common in people with HIV (PWH), however the link between dopamine (DA) and depression in PWH is poorly characterized. This study investigated CSF dopaminergic biomarkers, specifically DA and its metabolite, homovanillic acid (HVA), and examined their relationship with depressive symptoms and CSF neuroinflammatory markers in PWH and HIV-seronegative (HIV-) individuals.

METHODS

Participants were 102 HIV- individuals and 123 PWH (mean age = 42) who underwent neuropsychiatric evaluations and lumbar puncture. Current depression severity was classified using the Beck Depression Inventory-II (BDI-II). CSF was assayed for DA and HVA using high performance liquid chromatography and neuroinflammatory markers using immunoassays. Linear regressions modelled BDI-II scores as a function of HIV, dopaminergic biomarker z-scores, and their interaction, controlling for psychosocial factors. Correlational analyses examined dopaminergic and neuroinflammatory relationships.

RESULTS

PWH had significantly higher BDI-II scores than HIV- participants. DA and HVA were not associated with HIV status but both significantly moderated the effect of HIV on BDI-II scores, such that PWH exhibited higher depressive symptoms than HIV- participants only at lower concentrations of HVA (z ≤ 0.06) and DA (z ≤ 0.11). In PWH only, lower HVA significantly correlated with higher BDI-II scores and higher neuroinflammation, including higher MCP-1 and IP-10.

CONCLUSIONS

Results suggest that the pathophysiology of depression in PWH differs from that in HIV- individuals. Specifically, lower central dopaminergic activity was selectively associated with greater depressive symptoms and neuroinflammation in PWH. With the rise in consideration of DA agonists for the treatment of depression, these results suggest that PWH may show a greater response to these agents than their HIV- peers.

Prevalence and factors associated with severe depressive symptoms in older west African people living with HIV

BACKGROUND

Depression is one of the most common psychiatric disorders in people living with HIV (PLHIV). Depression has a negative impact on both mental and physical health and is mainly associated with suboptimal HIV treatment outcomes. To encourage successful aging and the achievement of the 3 × 90 objectives in older PLHIV, the psychological domain must not be neglected. In this context and as data are scarce in West Africa, this study aimed to evaluate the prevalence and the factors associated with severe depressive symptoms in older PLHIV living in this region of the world.

METHODS

Data from PLHIV aged ≥50 years and on ART since ≥6 months were collected in three clinics (two in Côte d'Ivoire, one in Senegal) participating in the West Africa International epidemiological Databases to Evaluate AIDS (IeDEA) collaboration. The severity of depressive symptoms was measured using the Center for Epidemiological Studies Depression scale (CES-D), and associated factors were identified using logistic regressions.

RESULTS

The median age of the 334 PLHIV included in the study was 56.7 (53.5-61.1), 57.8% were female, and 87.1% had an undetectable viral load. The prevalence of severe depressive symptoms was 17.9% [95% Confidence Interval (95% CI): 13.8-22.0]. PLHIV with severe depressive symptoms were more likely to be unemployed (adjusted Odd Ratio (aOR) = 2.8; 95% CI: 1.4-5.7), and to be current or former tobacco smokers (aOR = 2.6; 95% CI: 1.3-5.4) but were less likely to be overweight or obese (aOR = 0.4; 95% CI: 0.2-0.8).

CONCLUSIONS

The prevalence of severe depressive symptoms is high among older PLHIV living in West Africa. Unemployed PLHIV and tobacco smokers should be seen as vulnerable and in need of additional support. Further studies are needed to describe in more details the reality of the aging experience for PLHIV living in SSA. The integration of screening and management of depression in the standard of care of PLHIV is crucial.

Association of HIV serostatus and metabolic syndrome with neurobehavioral disturbances

Metabolic syndrome (MetS), a constellation of related metabolic risk factors, is a common comorbidity associated with cognitive difficulty in people living with HIV (PLWH). Neurobehavioral disturbances (e.g., behavioral manifestations of frontal-subcortical dysfunction) are also prevalent in HIV, yet the role MetS might play in HIV-associated neurobehavioral disturbances is unknown. Thus, we examined the link between MetS and neurobehavioral disturbances in PLWH. Participants included 215 adults (117 PLWH, 98 HIV-uninfected), aged 36 to 65 years, from a cohort study at the University of California San Diego. Using the Frontal Systems Behavior Scale, we captured neurobehavioral disturbances (apathy, disinhibition, and executive dysfunction). MetS was defined by the National Cholesterol Education Program's Adult Treatment Panel-III criteria. Covariates examined included demographic, neurocognitive impairment, and psychiatric characteristics. When controlling for relevant covariates, both HIV serostatus and MetS were independently associated with greater apathy and executive dysfunction. HIV, but not MetS, was associated with greater disinhibition. The present findings suggest an additive effect of HIV and MetS on specific neurobehavioral disturbances (apathy and executive dysfunction), underscoring the importance of identifying and treating both HIV and MetS to lessen central nervous system burden among PLWH.

Pre-frailty predicts cognitive decline at 2-year follow-up in persons living with HIV

Both HIV disease and frailty syndrome are risk factors for neurocognitive impairment. Longitudinal research among individuals of the general population suggests that frailty predicts future cognitive decline; however, there is limited evidence for these longitudinal relationships among people living with HIV (PLWH). The current study evaluated and compared rates of cognitive decline over 2 years among HIV serostatus and frailty status groups. Participants included 50 PLWH and 60 HIV-uninfected (HIV-) participants who were evaluated at baseline and 2-year follow-up visits. Baseline frailty status (non-frail, pre-frail, and frail) was determined using fried frailty phenotype criteria. Neurocognitive functioning was measured using practice-effect corrected scaled scores derived from a comprehensive neuropsychological battery covering seven cognitive domains. Repeated measures analysis was used to estimate rates of global and domain-specific cognitive change from baseline to 2-year follow-up among each of six HIV/frailty status groups. Among PLWH, the pre-frail group demonstrated consistent declines in global cognitive functioning (B = - 0.029, p = 0.034), processing speed (B = - 0.047, p = 0.031), and motor functioning (B = - 0.048, p = 0.038). Among HIV- participants, pre-frail individuals also declined in global cognitive functioning and processing speed (ps ≤ 0.05). HIV- non-frail participants also declined in the cognitive domains of learning, delayed recall, and motor functioning; however, these declines appeared to be driven by relatively higher baseline scores among this group. Notably, 38% of PLWH changed in frailty status from baseline to follow-up, and those with stable pre-frailty demonstrated higher likelihood for cognitive decline; change in depressive symptoms did not relate to change in frailty status. Current findings highlight pre-frailty as an important clinical syndrome that may be predictive of cognitive decline among PLWH. Interventions to prevent or reduce frailty among vulnerable PLWH are needed to maintain optimal cognitive health.

The effect of varenicline on mood and cognition in smokers with HIV

RATIONALE

Barriers to smoking cessation, including negative affect and cognitive dysfunction, may contribute to high smoking rates among people living with HIV/AIDS (PLWH). Varenicline may help PLWH quit smoking by improving mood and cognition, yet this has not been explored.

OBJECTIVES

The goal of this study was to evaluate the effect of varenicline on mood and cognition among PLWH enrolled in a smoking cessation clinical trial.

METHODS

In this secondary analysis of a varenicline trial (NCT01710137), we assessed mood (depression, anxiety) and cognition (attention, working memory) at weeks 0 (baseline), 1, 3, and 12 (end-of-treatment, EOT). Primary outcomes were changes in mood and cognition from baseline to EOT. Secondarily, mood and cognition were evaluated as predictors of biochemically confirmed 7-day point-prevalence abstinence at EOT.

RESULTS

Overall, 173 subjects (87 varenicline, 86 placebo) were included. At EOT, varenicline reduced anxiety (P < 0.001), vs. placebo (P = 0.31; interaction P = 0.05). Across both treatment arms, reductions in anxiety from baseline to EOT were associated with a higher likelihood of abstinence (OR = 1.3, 95% CI 1.1 to 1.6, P = 0.01). There were no significant treatment by time interactions for cognition or depression.

CONCLUSIONS

These data suggest that varenicline operates, at least in part, by reducing anxiety. Anxiety should be an intervention target for smokers with HIV interested in quitting.

Social support moderates D-dimer and self-rated successful aging within people with HIV and older adults

Many factors can influence perceptions of successful aging (SA), including social isolation and poor physical health. We hypothesized that social support attenuates the negative effect of plasma D-dimer, a correlate of HIV and aging, on SA. Participants included 230 adults (134 people with HIV; PWH, 96 HIV-), ages 36-65, segregated into age cohorts with up to 5 yearly visits. Multilevel modeling examined longitudinal within-person associations between D-dimer, social support, and SA. Social support moderated the relationship between D-dimer and SA and was significant among PWH and older individuals (ages 56-65), but not HIV- or younger cohorts. This association was significant only at extreme levels of social support, with significant decreases in social support potentiating the negative impact of D-dimer on SA and significant increases in social support facilitating increased SA. Despite declining health, high social support may improve SA in PWH and older adults, and low support may be especially problematic for older adults.
