Psychosocial Syndemic Burden, Sexual Behaviors, and Engagement in HIV Prevention Care Among Sexual and Gender Minority Youths: United States, 2022.

Objectives. To examine linear and nonlinear associations between psychosocial syndemic factors and HIV risk and engagement in HIV prevention care among sexual and gender minority (SGM) youths. Methods. Between February and October 2022, we recruited 17 578 SGM youths aged 13 to 18 years in the United States for an online survey. We examined the relationship of syndemics (i.e., binge drinking, drug use, sexual victimization, and anti-lesbian, gay, bisexual, and transgender discrimination) with sexual behaviors (i.e., sexual initiation, condomless anal or vaginal sex, and number of sexual partners) and HIV prevention care (i.e., HIV testing, preexposure prophylaxis awareness and utilization) using regression. Results. Psychosocial syndemic burden (number of syndemic factors reported) was linearly and cubically associated with engagement in sexual behaviors. Psychosocial syndemic burden was linearly associated with higher HIV testing and preexposure prophylaxis awareness and cubically associated with higher preexposure prophylaxis utilization. Conclusions. Our findings are evidence of synergism across psychosocial syndemic factors regarding HIV risk and engagement in HIV prevention care among SGM youths in the United States. Public Health Implications. Multicomponent interventions may help reduce HIV risk and promote access to HIV prevention services among SGM individuals aged 13 to 18 years.

Syndemic Psychosocial Conditions among Youth Living with HIV: a Latent Class Analysis.

Drug use, mental distress, and other psychosocial factors threaten HIV care for youth living with HIV (YLWH). We aimed to identify syndemic psychosocial patterns among YLWH and examine how such patterns shape HIV outcomes. Using baseline data from 208 YLWH enrolled in an HIV treatment adherence intervention, we performed latent class analysis on dichotomized responses to 9 psychosocial indicators (enacted HIV stigma; clinical depression and anxiety; alcohol, marijuana, and illicit drug misuse; food and housing insecurity; legal history). We used multinomial logistic regression to assess latent class-demographic associations and the automatic Bolck-Croon-Hagenaars method to assess HIV outcomes by class. Mean age of participants was 21 years; two thirds identified as cis male, 60% were non-Hispanic Black, and half identified as gay. Three classes emerged: "Polydrug-Socioeconomic Syndemic" (n = 29; 13.9%), "Distress-Socioeconomic Syndemic" (n = 35, 17.1%), and "Syndemic-free" (n = 142, 69.0%). Older, unemployed non-students were overrepresented in the "Polydrug-Socioeconomic Syndemic" class. Missed/no HIV care appointments was significantly higher in the "Polydrug-Socioeconomic Syndemic" class (81.4%) relative to the "Syndemic-free" (32.8%) and "Distress-Socioeconomic Syndemic" (31.0%) classes. HIV treatment nonadherence was significantly higher in the "Polydrug-Socioeconomic Syndemic" class (88.5%) relative to the "Syndemic-free" class (59.4%) but not the "Distress-Socioeconomic Syndemic" class (70.8%). Lack of HIV viral load suppression was non-significantly higher in the "Polydrug-Socioeconomic Syndemic" class (29.7%) relative to the "Syndemic-free" (16.2%) and "Distress-Socioeconomic Syndemic" (15.4%) classes. Polydrug-using, socioeconomically vulnerable YLWH are at risk for adverse HIV outcomes, warranting tailored programming integrated into extant systems of HIV care.

Longitudinal Analysis of Overlapping Psychosocial Factors Predicting Incident Hospitalization Among Mixed HIV Serostatus Men who have Sex with Men in the Multicenter AIDS Cohort Study.

Men who have sex with men (MSM) are at increased risk for certain types of chronic diseases and mental health problems. Despite having extended survival in the highly active antiretroviral therapy (HAART) era, MSM living with HIV contend with aging-related diseases and complications with treatment. Consequent hospitalizations incur high costs, fear, low quality of life, and frailty. Unlike heterosexual men, MSM experience more structural violence and "syndemics" of psychosocial factors that not only accelerate HIV acquisition and transmission risk but also may increase morbidity, leading to greater rates of hospitalization. We aim to examine the impact of "syndemic" psychosocial factors on the incidence of hospitalization among geographically diverse MSM in the US. Participants were 1760 MSM from the Multicenter AIDS Cohort Study (MACS) between 2004 and 2019. We examined the relationship between six psychosocial factors (depression, stimulant use, smoking, heroin use, childhood sexual abuse, and intimate partner violence) and incident hospitalization (admission to a hospital for treatment). We found a positive dose-response relationship between the number of syndemic factors and hospitalization. MSM reporting five or more syndemic factors had over twice the risk of hospitalization compared to MSM without syndemic factors [aRR = 2.14 (95% CI = 1.56, 2.94)]. Psychosocial factors synergistically increased hospitalizations over time. The positive dose-response relationship between the number of syndemic factors and hospitalization and the synergistic effects of these factors underscore the need for interventions that disentangle the syndemics to reduce hospitalization and related costs and improve the quality of life among MSM.

Syndemic of Substance Abuse, Depression, and Type 2 Diabetes and Their Association with Retention in Care Among People Living with HIV.

Substance abuse (SA), depression, and type 2 diabetes (DM2) often co-occur among people living with HIV (PLHIV). Guided by a syndemic framework, this cross-sectional retrospective study examined the cumulative and interaction effects of SA, depression, and DM2 on retention in HIV care (RIC) among 621 PLHIV receiving medical care in central Pennsylvania. We performed logistic regression analysis to test the associations between SA, depression, and DM2 and RIC. To test the "syndemic" model, we assessed additive and multiplicative interactions. In an unadjusted model, a dose-response pattern between the syndemic index (total number of health conditions) and RIC was detected (OR for 1 syndemic factor vs. none: 1.01, 95% CI: 0.69-1.47; 2 syndemic factors: 1.59, 0.89-2.84; 3 syndemic factors: 1.62, 0.44-5.94), but no group reached statistical significance. Interactions on both additive and multiplicative scales were not significant, demonstrating no syndemic effect of SA, depression, and DM2 on RIC among our study sample. Our findings highlight that comorbid conditions may, in some populations, facilitate RIC rather than act as barriers, which may be due to higher levels of engagement with medical care.

Exploring a syndemic of poverty, cumulative violence, and HIV vulnerability among refugee youth: multi-method insights from a humanitarian setting in Uganda.

Synergistic associations between social inequities and HIV vulnerabilities - known as a syndemic - are understudied with youth in humanitarian settings. We explored refugee youths' HIV prevention needs in Bidi Bidi Refugee Settlement, Uganda. This multi-methods study involved 6 focus groups and 12 in-depth individual interviews (IDI) with refugee youth (n = 60) aged 16-24, and IDI with refugee elders (n = 8) and healthcare providers (n = 8). We then conducted cross-sectional surveys with refugee youth (16-24 years) (n = 115) to assess: poverty, recent sexual and gender-based violence (SGBV), and condom engagement motivation (CEM) (wanting to learn about condoms for HIV prevention). Multivariable logistic regression was used to estimate adjusted odds ratios for associations between poverty and SGBV with CEM. Qualitative narratives revealed poverty and trauma elevated substance use, and these converged to exacerbate SGBV. SGBV and transactional sex increased HIV vulnerabilities. Among survey participants, poverty and recent SGBV were associated with reduced odds of CEM. The interaction between poverty and recent SGBV was significant: the predicted probability of CEM among youth who experienced both poverty and SGBV was almost half than among youth who experienced poverty alone, SGBV alone, or neither. Findings signal the confluence of poverty, violence, and substance use elevate refugee youth HIV vulnerabilities.

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 collaborative framework for the management of tuberculosis and type 2 diabetes syndemic in low- and middle-income countries: a rapid review.

INTRODUCTION: Given the absence of international guidelines on the joint management and control of tuberculosis (TB) and type 2 diabetes mellitus (T2D), the World Health Organization (WHO) and the International Union Against Tuberculosis and Lung Disease (The Union) launched in 2011 a policy framework to address the growing syndemic burden of TB-T2D. This review aimed at mapping the available evidence on the implementation of the Union-WHO Framework, explicitly, or bi-directional TB-T2D health programs as an initiative for co-management in patients in low- and middle-income countries (LMIC). METHODS: A rapid review was performed based on a systematic search in PubMed and Web of Science electronic databases for peer-reviewed articles on The Union-WHO Framework and bi-directional interventions of TB and T2D in LMIC. The search was restricted to English language articles and from 01/08/2011 to 20/05/2022. RESULTS: A total of 24 articles from 16 LMIC met the inclusion criteria. Four described the implementation of The Union-WHO Framework and 20 on the bi-directional interventions of TB and T2D. Bi-directional activities were found valuable, feasible and effective following the Union-WHO recommendations. Limited knowledge and awareness on TB-T2D comorbidity was identified as one of the barriers to ensure a functional and effective integration of services. CONCLUSIONS: This review revealed that it is valuable, feasible and effective to implement bi-directional TB and T2D activities (screening and management) according to the Union-WHO Framework recommendations, especially in countries that face TB-T2D syndemic. Additionally, it was apparent that gaps still exist in research aimed at providing evidence of costs to implement collaborative activities. There is need for TB and T2D services integration that should be done through the well-stablished TB programme. This integration of two vertical programmes, could ensure patient-centeredness, continuum of care and ultimately contribute for health systems strengthening.

The influence of a hostile environment on a syndemic of depression, stress and chronic limiting illness among LGBTQ+ people during the COVID-19 pandemic.

Lesbian, Gay, Bisexual, Transgender, Queer, Questioning (LGBTQ+) are at greater risk of poorer COVID-19 prognosis due to higher levels of chronic disease and a greater impact on mental health from pandemic mitigation strategies due to worse pre-pandemic mental health. We examine how a hostile social system contributes to LGBTQ+ people's negative health experiences during the pandemic through adopting a syndemic framework and using data from The Queerantine Study, a cross-sectional, web-based survey (n = 515). Identification of a health syndemic is based on depressive symptoms, perceived stress and limiting long-term illness. We used Latent Class Analysis to identify latent classes based on experiences of a hostile social system. A syndemic was identified among a third of respondents (33.2%), with transgender/gender-diverse and younger participants at higher risk. Latent Class Analysis identified five groups based on experiences of hostile social systems using psychosocial and socioeconomic indicators. Classes reflecting psychosocial hostility were predictive of a health syndemic and worsening health. This study emphasises (i) mental and physical health issues are intertwined among LGBTQ+ people; (ii) experiences of hostile social systems can account for part of variation in health across LGBTQ+ groups; (iii) that psychosocial hostility continued and was exacerbated throughout the pandemic, and (iv) experiences of psychosocial hostility in particular were associated with a greater likelihood of experiencing a syndemic.

Evidence of syndemic effects influencing older transgender persons' likelihood of contemplating suicide: results from a large national study.

OBJECTIVES: Very little research has examined suicidal ideation or the factors associated with contemplating suicide among older transgender adults. This paper examines whether or not there is evidence of syndemic effects influencing suicidal ideation among transgender persons aged 50 or older. METHODS: Data from the 2015 U.S. National Transgender Survey were used to examine five domains of potentially-syndemic effects (workplace issues, interactions with professionals, using public services, personal safety, and socioeconomic disadvantages) in a sample of 3,724 transgender Americans aged 50 or older. A dichotomous measure of suicidal ideation during the past year was the main outcome measure. RESULTS: The odds of contemplating suicide increased anywhere from 96% to 121% among people experiencing any of the problems under study, and anywhere from 258% to 1,552% (depending upon the syndemic effect domain in question) when they were faced by all of the experiences included in any particular domain. When all items were combined, exposure to any of the domains' problems elevated the risk of contemplating suicide by 276% and exposure to all of the problems examined increased the risk by 861%. The syndemic effects measure remained significant in multivariate analysis controlling for the influence of other potentially-relevant factors. CONCLUSIONS: Considerable evidence for the presence of syndemic effects was found, demonstrating that the more different types of adverse conditions that older transgender person's face, the more likely they are to experience to contemplate suicide. There is evidence that these effects diminish with advancing age.

Sex work, syndemic conditions and condomless anal intercourse among men who have sex with men who engage in sex work in Latin America.

Background In Latin American countries and Suriname, sexual transmission is one of the most common modes of HIV transmission, and men who have sex with men (MSM) who engage in sex work constitute a key population. Methods In a sample of MSM (N =53,166) from the Latin American Internet Survey (2018) across 18 countries, we examined how sex work engagement is associated with syndemic conditions (multidrug use, homophobic abuse, depression/anxiety, alcohol dependency (CAGE alcohol questionnaire) and internalised homonegativity) and condomless anal intercourse with non-steady male partners using separate logistic regressions. We then used a structural equation model to determine if and how syndemic conditions mediate the relationship between sex work engagement and non-steady male partners. Results We found that getting paid for sex was associated with less condom use for anal intercourse with non-steady male partners and particular syndemic conditions, such as multidrug use, homophobic abuse and alcohol dependency. In our structural equation model, the results showed that the direct relationship between sex work engagement and non-steady male partners was positive and significant, and syndemic conditions partially mediated this relationship. Conclusion Our results highlight the continuing need for including MSM who engage in sex work and those who experience syndemic conditions in the prevention strategies targeted to MSM in Latin America and Suriname, to prevent the transmission of HIV.

Airways Type-2 Related Disorders: Multiorgan, Systemic or Syndemic Disease?

Chronic rhinosinusitis (CRS) has recently undergone a significant paradigm shift, moving from a phenotypical classification towards an "endotype-based" definition that places more emphasis on clinical and therapeutic aspects. Similar to other airway diseases, like asthma, most cases of CRS in developed countries exhibit a dysregulated type-2 immune response and related cytokines. Consequently, the traditional distinction between upper and lower airways has been replaced by a "united airway" perspective. Additionally, type-2 related disorders extend beyond respiratory boundaries, encompassing conditions beyond the airways, such as atopic dermatitis. This necessitates a multidisciplinary approach. Moreover, consideration of possible systemic implications is crucial, particularly in relation to sleep-related breathing diseases like Obstructive Sleep Apnoea Syndrome (OSAS) and the alteration of systemic inflammatory mediators such as nitric oxide. The trends in epidemiological, economic, and social burden are progressively increasing worldwide, indicating syndemic characteristics. In light of these insights, this narrative review aims to present the latest evidence on respiratory type-2 related disorders, with a specific focus on CRS while promoting a comprehensive perspective on the "united airways". It also introduces a novel concept: viewing these conditions as a multiorgan, systemic, and syndemic disease.

A community psychology for migrant justice: Critically examining border violence and resistance during the COVID-19 syndemic.

This article explores the magnifying lenses of the COVID-19 syndemic to highlight how people racialized as migrants and refugees have been-and continue to be-disproportionally harmed. We use empirical evidence collected in our scholarly/activist work in Europe, Africa, South Asia, and the United States to examine migrant injustice as being produced by a combination of power structures and relations working to maintain colonial global orders and inequalities. This is what has been defined as "border imperialism." Our data, complemented by evidence from transnational solidarity groups, show that border imperialism has further intersected with the hygienic-sanitary logics of social control at play during the COVID-19 period. This intersection has resulted in increasingly coercive methods of restraining people on the move, as well as in increased-and new-forms of degradation of their lives, that is, an overall multiplication of border violences. At the same time, however, COVID-19 has provided a unique opportunity for grassroot solidarity initiatives and resistance led by people on the move to be amplified and extended. We conclude by emphasizing the need for community psychologists to take a more vigorous stance against oppressive border imperialist regimes and the related forms of violence they re/enact.

A Dynamic Spatial Factor Model to Describe the Opioid Syndemic in Ohio.

BACKGROUND: The opioid epidemic has been ongoing for over 20 years in the United States. As opioid misuse has shifted increasingly toward injection of illicitly produced opioids, it has been associated with HIV and hepatitis C transmission. These epidemics interact to form the opioid syndemic. METHODS: We obtain annual county-level counts of opioid overdose deaths, treatment admissions for opioid misuse, and newly diagnosed cases of acute and chronic hepatitis C and newly diagnosed HIV from 2014 to 2019. Aligned with the conceptual framework of syndemics, we develop a dynamic spatial factor model to describe the opioid syndemic for counties in Ohio and estimate the complex synergies between each of the epidemics. RESULTS: We estimate three latent factors characterizing variation of the syndemic across space and time. The first factor reflects overall burden and is greatest in southern Ohio. The second factor describes harms and is greatest in urban counties. The third factor highlights counties with higher than expected hepatitis C rates and lower than expected HIV rates, which suggests elevated localized risk for future HIV outbreaks. CONCLUSIONS: Through the estimation of dynamic spatial factors, we are able to estimate the complex dependencies and characterize the synergy across outcomes that underlie the syndemic. The latent factors summarize shared variation across multiple spatial time series and provide new insights into the relationships between the epidemics within the syndemic. Our framework provides a coherent approach for synthesizing complex interactions and estimating underlying sources of variation that can be applied to other syndemics.

Characterising a syndemic among black women at risk for HIV: the role of sociostructural inequity and adverse childhood experiences.

Objectives Black women disproportionately experience STIs (including HIV/AIDS), gender-based violence, substance misuse and mental health conditions. Addressing a gap in syndemic research, we characterised comorbidity overlap within the context of sociostructural inequities and adverse childhood experiences (ACEs) among black women in Baltimore, Maryland. Methods Between 2015 and 2018, black women (n=305) were recruited from STI clinics in Baltimore, Maryland. Among those with complete survey data (n=230), we conducted a latent class analysis to differentiate women based on their profile of the following syndemic comorbidities: STIs, adult sexual victimisation, substance misuse and mental health disorders. We then examined the association between ACEs and syndemic latent class membership. Results Thirty-three percent of women experienced three to nine ACEs before age 18 years, and 44% reported four to six comorbidities. The two-class latent class solution demonstrated the best fit model, and women were categorised in either class 1 (past-year STI; 59%) or class 2 (syndemic comorbidities; 41%). Women in class 2 were more likely to report unstable housing (10% vs 3%) and identify as bisexual/gay (22% vs 10%) than women in class 1. ACEs were significantly associated with an increased likelihood of class 2 membership. Conclusions This study reinforces the importance of screening for ACEs and offering trauma-informed, integrated care for black women with syndemic comorbidities. It also highlights the critical nature of tailoring interventions to improve sociostructural equity, preventing and reducing syndemic development.

Epidemiology of Heart Failure: A Contemporary Perspective.

Designated as an emerging epidemic in 1997, heart failure (HF) remains a major clinical and public health problem. This review focuses on the most recent studies identified by searching the Medline database for publications with the subject headings HF, epidemiology, prevalence, incidence, trends between 2010 and present. Publications relevant to epidemiology and population sciences were retained for discussion in this review after reviewing abstracts for relevance to these topics. Studies of the epidemiology of HF over the past decade have improved our understanding of the HF syndrome and of its complexity. Data suggest that the incidence of HF is mostly flat or declining but that the burden of mortality and hospitalization remains mostly unabated despite significant ongoing efforts to treat and manage HF. The evolution of the case mix of HF continues to be characterized by an increasing proportion of cases with preserved ejection fraction, for which established effective treatments are mostly lacking. Major disparities in the occurrence, presentation, and outcome of HF persist particularly among younger Black men and women. These disturbing trends reflect the complexity of the HF syndrome, the insufficient mechanistic understanding of its various manifestations and presentations and the challenges of its management as a chronic disease, often integrated within a context of aging and multimorbidity. Emerging risk factors including omics science offer the promise of discovering new mechanistic pathways that lead to HF. Holistic management approaches must recognize HF as a syndemic and foster the implementation of multidisciplinary approaches to address major contributors to the persisting burden of HF including multimorbidity, aging, and social determinants of health.

Spatial Analysis of the Alcohol, Intimate Partner Violence, and HIV Syndemic Among Women in South Africa.

The co-occurrence of and synergistic interactions between substance abuse, violence, and HIV, known as the "SAVA syndemic," is thought to be a driver of women's elevated risk for HIV in sub-Saharan Africa. This study uses data from the 2016 South African Demographic and Health Survey (DHS) and the 2016 South African Census to examine geospatial associations between alcohol use, intimate partner violence (IPV), unprotected sex, and HIV status among a population-based sample of 8528 South African women (age 15-49). Results support the geographic clustering of alcohol use, unprotected sex, and IPV, but not HIV, and geospatial clustering of HIV alone. This study highlights the need for geographically-tailored interventions to address syndemics through integrated interventions, such as those simultaneously focused on alcohol, IPV, and sexual risk reduction, and points to the need for more targeted research to link these factors to HIV from a place-based risk perspective.

Characterizing HIV Syndemics and the Role of Incarceration Among Men Who have Sex with Men Presenting for Care at a Sexually Transmitted Infections Clinic.

Men who have sex with men (MSM) with a history of incarceration experience unique risk factors for HIV acquisition. The current study examined unique risk factors for HIV among MSM with a history of incarceration presenting to a sexually transmitted infections (STI) clinic. We analyzed self-reported behavioral data from clinical encounters among patients attending the clinic between January 2012 and April 2021. There were 17,221 unique visits, of which 5988 were MSM. Of these, 4.34% (N = 206) were MSM with a history of incarceration. MSM with a history of incarceration were significantly more likely to report a range of behavioral risk factors for HIV, yet also were significantly less likely to perceive themselves at risk for HIV. Future research and practice should develop culturally tailored biobehavioral HIV prevention services and consider embedding these programs within criminal justice settings to better reach this at-risk group.

Intersecting Relationships of Psychosocial and Structural Syndemic Problems Among People with HIV in South Africa: Using Network Analysis to Identify Influential Problems.

In South Africa, little is known about interrelationships between syndemic problems among people with HIV (PWH). A better understanding of syndemic problems may yield important information regarding factors amenable to mitigation. We surveyed 194 PWH in Khayelitsha, outside of Cape Town, South Africa. We used network analysis to examine the frequency of 10 syndemic problems and their interrelationships. Syndemic problems among PWH in South Africa were common; 159 (82.8%) participants reported at least 2 co-occurring syndemic problems and 90 (46.9%) endorsed 4 or more. Network analysis revealed seven statistically significant associations. The most central problems were depression, substance use, and food insecurity. Three clusters of syndemics were identified: mood and violence; structural factors; and behavioral factors. Depression, substance use, and food insecurity commonly co-occur among PWH in sub-Saharan Africa and interfere with HIV outcomes. Network analysis can identify intervention targets to potentially improve HIV treatment outcomes.

RESUMEN: En Sudáfrica, poco se sabe sobre interrelaciones entre problemas sindémicos entre personas con VIH (PCV). Un major entendimiento de los problemas sindémicos puede arrojar información importante sobre los factores susceptibles de mitigación. Utilizamos el análisis de redes para examinar la frecuencia de 10 problemas sindémicos y sus interrelaciones. Problemas sindémicos entre PCV en Sudáfrica eran communes; 159 (82.8%) participantes presentaron al menos 2 problemas sindémicos concurrentes y 90 (46.9%) presentaron 4 o más. El análisis de red reveló siete asociaciones estadísticamente significativas. Los problemas más centrales fueron la depresión, el uso de sustancias y la inseguridad alimentaria. Se indetificaron tres grupos de sindemias: estado de ánimo y violencia; factores estructurales; y factores de comportamiento. La depresión, el uso de sustancias y la inseguridad alimentaria comúnmente ocurren simultáneamente entre las PCV en el África subsahariana e interfieren con los resultados del VIH. El análisis de redes puede identificar objetivos de intervención para potencialmente mejorar los resultados del tratamiento del VIH.

Psychosocial Syndemic Classes and Longitudinal Transition Patterns Among Sexual Minority men Living with or Without HIV in the Multicenter AIDS Cohort Study (MACS).

Mental health and substance use epidemics interact to create psychosocial syndemics, accelerating poor health outcomes. Using latent class and latent transition analyses, we identified psychosocial syndemic phenotypes and their longitudinal transition pathways among sexual minority men (SMM) in the Multicenter AIDS Cohort Study (MACS, n = 3,384, mean age 44, 29% non-Hispanic Black, 51% with HIV). Self-reported depressive symptoms and substance use indices (i.e., smoking, hazardous drinking, marijuana, stimulant, and popper use) at the index visit, 3-year and 6-year follow-up were used to model psychosocial syndemics. Four latent classes were identified: "poly-behavioral" (19.4%), "smoking and depression" (21.7%), "illicit drug use" (13.8%), and "no conditions" (45.1%). Across all classes, over 80% of SMM remained in that same class over the follow-ups. SMM who experienced certain psychosocial clusters (e.g., illicit drug use) were less likely to transition to a less complex class. These people could benefit from targeted public health intervention and greater access to treatment resources.

Association of syndemic conditions and quality of life among people living with HIV/AIDS.

The syndemics theory seeks to understand the effect of multiple synergic problems in promoting poor health outcomes. To disentangle which and how syndemic conditions affect the quality of life (QoL) may be important to improve well-being of people living with HIV/AIDS (PLWHA). This study evaluates the association between syndemic conditions and QoL among PLWHA. We performed a secondary analysis using data obtained between 2014 and 2017 among PLWHA under care in Rio de Janeiro, Brazil. The outcomes were the six QoL domains (physical, psychological, level of independence, social relationships, environmental, and spirituality) measured through the World Health Organization Quality of Life in HIV infection scale, abbreviated version (WHOQOL-HIV-BREF). The independent variables were demographic and clinical characteristics, syndemic conditions (binge drinking, compulsive sexual behavior, polysubstance use, intimate partner violence, and depression), and syndemics (two or more syndemic conditions simultaneously). Bivariate analysis (t-test and ANOVA) and linear regressions were performed for each quality-of-life domain. The analytical sample comprised 1530 participants, mostly male at birth (64%) and with median age of 43 years. The syndemic conditions most frequently observed were binge drinking (56%), IPV (13%), and depression (9%). Both individual syndemic conditions and syndemics were associated with worse QoL. In the multivariate analysis, positive screening for depression was associated with worse QoL in all domains. Polysubstance users presented worse QoL at social and environmental domains. Intimate partner violence was associated with worse QoL at environment domain while binge drinking was associated with worse scores in the physical domain. The presence of syndemics increased the likelihood of worse scores in the psychological, social, and environment domains. Our study expands the understanding of QoL in PLWHA, as it considers a holistic/integral, multifactorial, and synergistic approach to the determinants of QoL. Seeking strategies that target syndemics may be important to improve patient-centered outcomes in health.Abbreviations: HIV/AIDS: human immunodeficiency virus/acquired immunodeficiency syndromeWHO: World Health OrganizationQoL: quality of lifeHRQoL: health-related quality of lifePLWHA: people living with HIV/AIDScART: combined antiretroviral therapyIPV: intimate partner violenceINI/FIOCRUZ: Evandro Chagas National Institute of Infectious DiseasesOswaldo Cruz FoundationSRH: self-rated healthVL: viral loadCD4: CD4 cell countNIAAA: National Institute on Alcohol Abuse and AlcoholismCSBcompulsive sexual behaviorWHO-ASSIST: alcoholsmoking and substance involvement screening test developed by the World Health OrganizationPHQ-2: Patient Health Questionnaire-2.
