Syndemic conditions and medication adherence in older men living with HIV who have sex with men

Impact of mental disorders on low adherence to antiretroviral therapy in people living with HIV in Spain

The relationship between mental disorders other than depression or anxiety, and low adherence to both antiretroviral treatment (ART) and linkage to HIV care are unclear. The aim of our study was to compare the prevalence of mental disorders in people living with HIV (PLHIV) in Spain who present low versus high adherence to ART. We performed a cross-sectional study comparing two groups of PLHIV: 20 PLHIV with low adherence and 80 PLHIV with high adherence to ART. PLHIV who met at least one of the following criteria were included in the low-adherence group: virological failure (HIV-VL > 50 copies/mL in two consecutive blood samples); low attendance to scheduled clinical visits (≥2 missed visits in last year); irregular administration of ART (≥10 forgotten doses in the last month); and interruption of ART for more than 1 week. Inclusion criteria for high adherence were: PLHIV who had been on stable ART for more than 1 year with an HIV-VL below 50 copies/mL and without missed visits over the previous 12 months. The Millon Clinical Multiaxial Inventory was administered to participants. PLHIV with low adherence showed higher scores for all mental disorders compared with those with high adherence. And, in the multivariate binary logistic regression analysis, drug dependence and post-traumatic stress disorder were independently associated with low adherence (Nagelkerke R2 = 0.0686). In conclusion, PLHIV with poorly controlled HIV infection presented important psychological vulnerabilities. Mental health should be checked at the beginning of ART and during follow-up, especially in PLHIV with low adherence or low linkage to the health care system.

Convergence between Cardiometabolic and Infectious Diseases in Adults from a Syndemic Perspective: A Scoping Review

Objective. Synthesize the approaches used to study the convergence between cardiometabolic and infectious diseases in adults from a syndemic perspective based on the scientific evidence available to date worldwide. Methods. Scoping review that follows the recommendations of the PRISMA statement. The protocol was registered in INPLASY202150048. The search for studies was carried out in MEDLINE, LILACS, Web of Science and Scopus. Results. Since the COVID-19 pandemic, there has been an increase in studies in the field of convergence between cardiometabolic and infectious diseases from a syndemic perspective, but only three studies were classified as true syndemics. There are weaknesses in the adherence to the elements of the syndemic theory, given a low incorporation of population measurements, and until now it has not been possible to find convincing empirical evidence that supports the bio-bio interface. Quantitative methods predominated through models focused on "sum scores". Conclusions. Future studies should comprehensively address the elements of syndemics, review discrepancies between additive analyses versus other modeling, and incorporate the influence of large-scale social forces. The lack of these aspects distances studies from the notion of syndemic, bringing them closer to comorbidity or multimorbidity approaches.

An exploratory study of community violence and HIV care engagement among Black gay and bisexual men

This study examined the relationship between exposure to community violence and HIV care engagement among 107 Black gay or bisexual men living with HIV in Chicago. Measures assessed the importance of demographic covariates (age, annual income, health insurance status, and years living with HIV), community violence exposures, mental health, social support, in explaining variations in missed doses of antiretroviral therapy (ART) medication and missed HIV care appointments. Results showed that participants who reported higher rates of exposure to community violence were two times more likely to have missed ART doses and HIV care appointments. Participants who reported depression scores were two times more likely to have greater non-ART adherence. Finally, older participants were more likely to report fewer missed ART doses. More research is needed to clarify the mechanisms between age or depression and ART adherence given community violence exposure. Health care providers should screen for depression when attempting to promote better ART adherence and keeping HIV care appointments for Black gay and bisexual men living with HIV. Younger Black gay and bisexual men living with HIV may be more vulnerable than older men for missed ART doses and may require additional screening and follow-up.

Do syndemic conditions predict HIV medication adherence among urban African American men?

Much progress has been made in advancing antiretroviral (ART) adherence, yet disparities remain. To explore relationships of syndemic conditions - co-occurring health conditions caused by combinations of biological, social, and structural factors - to ART adherence among African American men, we used data from longitudinal assessments of 302 African American men enrolled in a study designed to increase physical activity and healthy eating. Syndemic conditions included alcohol dependency, drug dependency, depression, post-traumatic stress disorder, and unstable housing. A syndemic conditions variable was operationalized to indicate the presence of 0-5 conditions. About 55% of participants had 1 or more syndemic conditions. Age and marriage were positively associated with ART adherence, whereas number of syndemic conditions was negatively associated with adherence during the 12-month period. The interaction of being married and the syndemic conditions variable significantly predicted greater adherence. Similarly, the interaction of more education and the syndemic conditions variable predicted greater adherence. In multiple regression models, the syndemic conditions variable remained significant (-0.018) in predicting adherence; however, there was no significant interaction among the 5 conditions. This study lends evidence to syndemics literature indicating deleterious consequences of negative life experiences on health outcomes.

The impact of syndemic burden, age, and sexual minority status on internalized HIV stigma among people living with HIV in South Florida

Internalized HIV stigma has been associated with several poor mental and physical health outcomes among people living with HIV (PLWH); yet, little research has explored how internalized HIV stigma may be affected by syndemic burden. This study sought to examine the relationship between syndemic conditions and HIV stigma over and above the potential effects of two social determinants of health, age and sexual minority status, using a linear regression approach (N = 1343). Syndemic burden was significantly positively associated with internalized HIV stigma above and beyond the effects of age and sexual minority status (b = 0.23). Additionally, age (b = -0.02) and being a sexually minority (b = -0.31) were significantly negatively associated with internalized HIV stigma. Findings should inform future treatment targets for this population by specifically working to reduce internalized HIV stigma for people with a greater syndemic burden and, potentially, among young adults and heterosexual PLWH.

The Relationship Between Posttraumatic Stress Disorder and Alcohol Misuse and Smoking Among Aging Men Who Have Sex With Men: No Evidence of Exercise or Volunteering Impact

OBJECTIVES

To determine if the association between posttraumatic stress disorder (PTSD) and substance use (alcohol misuse or smoking tobacco) is mediated/moderated by exercise or volunteering among aging (≥40 years) men who have sex with men (MSM), and if this mediation/moderation differs by HIV serostatus.

METHODS

Multicenter AIDS Cohort Study data were used. Three datasets with PTSD measured during different time periods (10/1/2017-3/31/2018, 898 men; 4/1/2018-9/30/2018, 890 men; 10/1/2018-3/31/2019, 895 men) were analyzed. Longitudinal mediation analyses estimated the mediation effect of exercise and volunteering on the outcomes.

RESULTS

Nine percent of MSM had evidence of PTSD. There was no statistically significant mediation effect of exercise or volunteering regardless of substance use outcome. The odds of smoking at a future visit among MSM with PTSD were approximately double those of MSM without PTSD. Results did not differ by HIV serostatus.

DISCUSSION

There is a particular need for effective smoking cessation interventions for aging MSM with PTSD.

Ageing with HIV: Medicine Optimisation Challenges and Support Needs for Older People Living with HIV: A Systematic Review

BACKGROUND

Older people living with HIV (PLWH) are at increased risks of co-morbidities and polypharmacy. However, little is known about factors affecting their needs and concerns about medicines. This systematic review aims to describe these and to identify interventions to improve medicine optimisation outcomes in older PLWH.

METHODS AND DATA SOURCES

Multiple databases and grey literature were searched from inception to February 2022 including MEDLINE, CINAHL, PsycInfo, PsychArticles, the Cochrane Database of Systematic Reviews and the Cochrane Controlled Register of Trials, Abstracts in Social Gerontology, and Academic Search Complete.

ELIGIBILITY CRITERIA

Studies reporting interventions/issues affecting older PLWH (sample populations with mean/median age ≥ 50 years; any aspect of medicine optimisation, or concerns). Quality assessments were completed by means of critical appraisal checklists for each study design. Title and abstract screening was led by one reviewer and a sample reviewed independently by two reviewers. Full-paper reviews were completed by one author and a 20% sample was reviewed independently by two reviewers.

SYNTHESIS

Data were extracted by three independent reviewers using standardised data extraction forms and synthesised according to outcomes or interventions reported. Data were summarised to include key themes, outcomes or concerns, and summary of intervention.

RESULTS

Seventy-nine (n = 79) studies met the eligibility criteria, most of which originated from the USA (n = 36). A few studies originated from Australia (n = 5), Canada (n = 5), Spain (n = 9), and the UK (n = 5). Ten studies originated from Sub-Saharan Africa (Kenya n = 1, South Africa n = 6, Tanzania n = 1, Uganda n = 1, Zimbabwe n = 1). The rest of the studies were from China (n = 1), France (n = 1), Germany (n = 1), Italy (n = 1), the Netherlands (n = 1), Pakistan (n = 1), Switzerland (n = 1), Saudi Arabia (n = 1) and Ukraine (n = 1). Publication dates ranged from 2002 to 2022. Sample sizes ranged from 10 to 15,602 across studies. The factors affecting older PLWH's experience of and issues with medicines were co-morbidities, health-related quality of life, polypharmacy, drug interactions, adverse drug reactions, adherence, medicine burden, treatment burden, stigma, social support, and patient-healthcare provider relationships. Nine interventions were identified to target older persons, five aimed at improving medication adherence, two to reduce drug interactions, and two for medicine self-management initiatives.

CONCLUSION

Further in-depth research is needed to understand older PLWH's experiences of medicines and their priority issues. Adherence-focused interventions are predominant, but there is a scarcity of interventions aimed at improving medicine experiences for this population. Multi-faceted interventions are needed to achieve medicine optimisation outcomes for PLWH.

Associations between psychosocial factors and antiretroviral therapy outcomes differ by gender and sexual orientation among people living with HIV in British Columbia, Canada

Little is known about how the co-occurrence of psychosocial factors affect sub-populations of people living with HIV (PLWH). We used cross-sectional data from 999 PLWH, aged ≥19, accessing antiretroviral therapy (ART) in British Columbia, Canada (2007-2010) to examine associations between psychosocial factors and ART-related outcomes separately for trans/cis inclusive women; heterosexual men; and gay, bisexual, and other men who have sex with men (gbMSM). Multivariable logistic regression examined associations between psychosocial factors (0-3): any violence in the past 6 months, depressive symptoms in the past week, and current street drug use (heroin, crack, meth or speedball) with sub-optimal adherence (outcome 1: average annual ART adherence <95% from interview until end of follow-up, death, or December 31st, 2018) and ever viral rebound (outcome 2) adjusting for potential confounders. Of 999 PLWH (264 women, 382 heterosexual men, and 353 gbMSM), women and heterosexual men had significantly higher median counts than gbMSM. Overall, higher counts were associated with sub-optimal adherence (adjusted odds ratio [aOR] = 1.26/1-unit increase, 95%CI = 1.07-1.49). All effect estimates were of a greater magnitude among gbMSM, but not significant for women or heterosexual men, highlighting the need for population (e.g., gender and sexual orientation)-centered care and research.

Abuse in the Continua: HIV Prevention and Care Outcomes and Syndemic Conditions Associated with Intimate Partner Violence Among Black Gay and Bisexual Men in the Southern United States

Intimate partner violence (IPV) has been implicated in HIV acquisition and worse HIV outcomes. Limited research focuses on the experiences of Black gay and bisexual men. Using data from cross-sectional surveys in Baltimore, Maryland, and Jackson, Mississippi, we analyzed the association between IPV victimization and HIV-related outcomes among 629 adult Black gay and bisexual men, among whom 53% self-reported a negative result at last HIV test. 40% of participants reported lifetime physical, sexual, and/or psychological IPV victimization, and 24% past-year victimization. Recent and lifetime IPV were associated with recent clinical diagnosis of STI (adjPrR: 1.44; 95%CI: 1.08-1.92) and ART medication interruptions (adjPrR: 1.59; 95%CI: 1.25-2.01), respectively. Physical IPV was inversely associated with current PrEP use (adjPrR: 0.35; 95%CI: 0.13-0.90). Recent IPV was independently correlated with depression symptomatology (adjPrR: 2.36; 95%CI: 1.61-3.47) and hazardous alcohol use (adjPrR: 1.93; 95%CI: 1.42-2.61), with evidence of interactions. IPV-HIV relationships were intersected by internalized stigma, housing instability, poverty, and lack of insurance. Tailored IPV services are urgently needed for comprehensive HIV services for Black gay and bisexual men in the U.S.

Mapping the current knowledge in syndemic research applied to men who have sex with men: A scoping review

Men who have sex with Men (MSM) represent a population affected by numerous health conditions. Syndemic theory has been used as a framework to study the health of MSM for nearly 20 years. However, the literature is plagued by a lack of consensus regarding what constitutes a synergy in a syndemic and recent reviews have shown that most of the papers published thus far have failed to demonstrate a synergy nor describe the bio-social interaction needed to account for a true syndemic. Moreover, to our knowledge, none of the existing reviews have focused specifically on MSM. This scoping review aims to fill this gap by mapping in detail how syndemic research on MSM has been conducted. A systematic database search was conducted between 2020 and 2021 and 115 studies were included. Our findings showed a lack of diversity regarding the location, design, subpopulation, and outcomes studied. In addition, the syndemic conditions, as well as their measurement, were not focused enough to ensure the robustness and reproducibility of the findings. Furthermore, our results support previous reviews showing a lack of empirical data to support disease interaction in syndemic research applied to MSM. Our review offers some important recommendations to help move the field forward in future work and describes some promising methodological advances.
