The Characteristics and HIV-Related Outcomes of People Living with Co-occurring HIV and Mental Health Conditions in the United States: A Systematic Review of Literature from 2016 to 2021.

Considering advances in HIV prevention and treatment, jurisdictional efforts to end the HIV/AIDS epidemic, and reduced stigma towards people living with HIV infection and mental health conditions, the authors systematically reviewed studies published between 2016 and 2021 and identified 45 studies that met the eligibility criteria. The review found that stigma towards mental health conditions still acts as a barrier to accessing HIV treatment, which impacts treatment outcomes. Additionally, social determinants of health, such as housing instability and poverty, appear to impact mental health and, therefore, HIV-related outcomes. The review also highlighted the mutually reinforcing effects of HIV, mental health, and substance use conditions, providing valuable insights into the syndemic effects of these co-occurring conditions. Overall, the review highlights the need to address stigma and social determinants of health in HIV prevention and treatment efforts and to integrate mental health services into HIV care to improve outcomes for people living with both HIV and mental health conditions.

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.

Drug use during the second year of the COVID-19 pandemic: observations from repeated cross-sectional surveys of sexual minority men in the US active on social networking applications.

Studies conducted early in the COVID-19 pandemic - before vaccines were widely available - indicated that drug use may have declined among sexual minority men (SMM). This study evaluated drug use trends in the second year of the pandemic. Cross-sectional responses from cisgender SMM living in the US and recruited online (n = 15,897) were grouped for analyses: Time 1: 3/1/2021-5/30/2021; Time 2: 6/1/2021-8/31/2021; Time 3: 9/1/2021-11/30/2021; and Time 4: 12/1 2021-2/28/2022. Results of multivariable models indicated that illicit drug use (excluding cannabis) increased at Times 2 (OR = 1.249, p < .001), 3 (OR = 1.668, p < .001), and 4 (OR = 1.674, p < .001) compared to Time 1. In contrast, cannabis use was relatively stable over time. Rates did not differ significantly among Times 1, 2, and 4. While rates of COVID-19 vaccination increased over time, illicit drug use was negatively associated with the odds of vaccination (OR = 0.361, p < .001). These findings highlight the need for ongoing attention to the risks drug use poses among SMM. Illicit drug use - a long-standing health disparity among SMM - increased significantly across the second year of the pandemic. Because they are less likely to be vaccinated, SMM who use illicit drugs may be at greater risk of COVID-19 infection or complications.

A systematic comparison of additive and interaction approaches to modeling the effects of syndemic problems on HIV outcomes in South Africa.

Much of the research on the effects of syndemics on HIV outcomes has utilized an additive approach. However, interaction effects may better account for syndemic synergy than an additive approach, but it remains difficult to specify interaction effects without empirical guidance. We sought to systematically compare additive and interaction effects approaches to modeling the effects of syndemic problems on antiretroviral therapy (ART) using empirically specified interaction terms. Participants were 194 people with HIV (PWH) who received HIV care in Khayelitsha, South Africa. In a series of linear regression models, we examined ten syndemic problems: depression, alcohol use, intimate partner violence (IPV), post-traumatic stress, social anxiety, substance use, food insecurity, poverty, housing instability, and structural barriers to care. Depression, substance use, and food insecurity were selected for interaction terms based on a prior network analysis, which found these problems to be most central. The additive models did not produce statistically significant findings. However, the interaction effects models yielded significant interaction terms in both the full model and a parsimonious model. There was a statistically significant effect of the interaction between depression and food insecurity on ART adherence (b = 0.04, Robust SE = 0.02, 95%CI [0.001-0.08], p = .012). This pattern of results was replicated in the parsimonious model. Findings suggest that when feasible, interaction effects approaches may be a helpful syndemic modeling technique. Results may inform future intervention targets, such as depression and food insecurity, and the importance of addressing both structural and psychosocial syndemic problems.

Testing a syndemics perspective on the effects of multiple adversities on depression and anxiety symptoms in a representative population sample.

PURPOSE: Considerable empirical evidence indicates that stressful life experiences may have a negative impact on mental health. However, it is unclear how multiple adverse experiences may intersect to influence symptoms of depression and anxiety. Using a syndemics approach to identify potential synergistic effects between major stressors, we aimed to quantify the roles of multiple recent adverse life experiences on depression and anxiety symptoms. METHODS: A population-representative sample of 1090 Australian adults (53% women, Mage 47 years) completed a cross-sectional survey in 2022 that assessed mental health and retrospective reports of nine specific stressful life experiences in the past year. RESULTS: The most common adverse life experiences in the past year were financial problems (64%), loneliness (63%), or a major health problem (51%). In multivariate logistic regression analyses, financial problems, personal health problems, health problems in a close contact, relationship problems and loneliness were significantly associated with both depression and anxiety symptoms (p < 0.05). There was just one synergistic interaction and one buffering interaction of combined adversities on anxiety, and no synergistic interactions of adverse experiences on depression. The perceived impact of combined adversities was associated with both depression (b = 0.59, p < 0.001) and anxiety (b = 0.48, p < 0.001). CONCLUSION: Adversity was strongly associated with depression and anxiety. Inconsistent with a syndemics framework, there were very few synergistic relationships between different types of adversities, suggesting that different adverse experiences may independently influence mental health. The findings indicate important opportunities for early intervention to prevent depression and anxiety during difficult times.

Drowning in the ripple effect: identifying a syndemic network of health experience (with modifiable health behaviours) using the UK Biobank.

A Syndemic model of health experience in severe mental illness (SMI) involving modifiable health behaviour contributors has been theorised but has not yet been investigated. Over the next 10 years mental ill-health and suicidal behaviours have been predicted to increase which will decrease health experience and increase hospitalisation and associated costs. This paper investigated a Syndemic model of health experience in people with SMI informed by physical activity levels, exposure to nature, personal resilience levels, drugs related (tobacco smoking and alcohol consumption), and sleep behaviours using UK Biobank data. Results implementing SEM indicate partial evidence for a Syndemic model, with personal resilience being at its centre. Contrary to previous findings, drugs related behaviours did not play an important role in the model. Implementing a Syndemic framework approach to current health care strategies could be beneficial in the development of self-management strategies for people with SMI. This is the first paper using SEM analyses to investigate SMI under the Syndemic theory paradigm.

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.

Comorbidities and extra-articular manifestations in difficult-to-treat rheumatoid arthritis: different sides of the same coin?

Despite the improvement in treatment for people with RA, ∼30% of patients remain symptomatic in the presence of optimized medical therapy, described as having 'difficult-to-treat' (D2T) RA. The average patient with RA has 1.6 other clinical conditions, which accumulate over time. Comorbidities are increasingly recognized as key contributors to D2T disease, and are themselves perpetuated by the D2T state. In this review, we discuss the commonest comorbidities in the context of D2T RA. We propose the need for a paradigm shift in the clinical and research agenda for comorbidities-including a need to consider and manage these prior to the development of D2T disease and not as an afterthought.

Co-occurring Epidemic Conditions Among Southern U.S. Black Men Who Have Sex with Men in an Online eHealth Intervention.

Black men who have sex with men (BMSM) face disproportionately higher risks for adverse sexual health outcomes compared to their non-Hispanic White counterparts. This disparity can be attributable to overlapping and intersecting risk factors at the individual and structural levels and can be understood through syndemic theory. Using longitudinal data from the HealthMPowerment trial (n = 363), six conditions related to stigma syndemics were indexed as a cumulative risk score: high alcohol use, polydrug use, depression and anxiety symptomology, and experiences of racism and sexual minority stigma. Using Poisson regression, we found a positive association between baseline risk scores and sexual risk behavior (b: 0.32, SE: 0.03, p < 0.001). Using a Generalized Estimating Equation, we also found a 0.23 decrease in the within-participant risk scores at 3-month follow-up (SE: 0.10, p < 0.020). Future work examining how care and prevention trials improve health outcomes in this population is needed.

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.

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.

Intersectional stigma and gender non-affirmation hinder HIV care engagement among transgender women living with HIV in India.

Among transgender women living with HIV (TGWLH) in India, little is understood about the mechanisms through which multiple intersecting stigmas impact HIV care engagement, or intervention strategies that might mitigate this impact. We conducted focus groups with TGWLH (N = 30) in three Indian cities and analysed data using theoretical frameworks related to HIV stigma, gender affirmation, and syndemics. Findings revealed that enacted and anticipated stigma due to transgender identity, HIV, or sex work status, and lack of gender affirmation (e.g., misgendering) in healthcare settings delayed ART initiation and promoted care disengagement. Having supportive physicians and counsellors within ART centres and peer outreach workers facilitated ART initiation, adherence, and retention. Findings also revealed that HIV stigma within TGW communities led to concealment of HIV status or syndemic conditions such as depression and alcohol use, thereby affecting care engagement. However, the TGW community itself was also described as a resilience resource, offering emotional, psychological and tangible support that decreased the impact of discrimination on care engagement. HIV care engagement efforts among Indian TGWLH could be strengthened by reducing intersecting stigmas in healthcare settings and within TGW communities, providing gender-affirming and culturally competent healthcare, addressing psychosocial syndemic conditions, and strengthening support within transgender communities.

Prevalence of depression, syndemic factors and their impact on viral suppression among female sex workers living with HIV in eThekwini, South Africa.

INTRODUCTION: Over half of female sex workers (FSW) in South Africa are living with HIV and clinical depression has been frequently documented among FSW. Data characterizing structural determinants of depression and the role of syndemic theory, synergistically interacting disease states, on viral suppression among FSW in South Africa are limited. METHODS: Between July 2018-March 2020, non-pregnant, cisgender women (≥ 18 years), reporting sex work as their primary income source, and diagnosed with HIV for ≥ 6 months were enrolled into the Siyaphambili trial in eThekwini, South Africa. Using baseline data, robust Poisson regression models were used to assess correlates of depression and associations between depression and syndemic factors on viral suppression. RESULTS: Of 1,384 participants, 459 (33%) screened positive for depression, defined as a score of ≥ 10 on the PHQ-9. Physical and sexual violence, drug use, alcohol use, anticipated stigma and internalized stigma were univariately associated with depression (all p's < 0.05) and included the multivariate model. In the multivariate regression, prevalence of depression was higher among participants experiencing sexual violence (PR = 1.47 95% CI:1.24,1.73), physical violence 5 times or more in < 6 months (PR = 1.38 95% CI:1.07, 1.80), using illicit drugs in the last month (PR = 1.23 95%:CI 1.04, 1.48), and reporting higher levels of internalized stigma (PR = 1.11, 95% CI:1.04,1.18). Depression in the absence of the Substance Abuse, Violence and AIDS SAVA syndemic factors was associated with increased prevalence of unsuppressed viral load (aPR 1.24; 95% CI:1.08,1.43), and the SAVA substance use and violence syndemic was associated with an increase in unsuppressed viral load among non-depressed FSW (aPR 1.13; 95% CI:1.01, 1.26). Compared to those experiencing neither factors, those jointly experiencing depression and the SAVA syndemics were at increased risk for unsuppressed viral load (aPR 1.15; 95% CI:1.02,1.28). CONCLUSION: Substance use, violence, and stigma were all associated with depression. Depression and syndemic factors (substance use + violence) were related to unsuppressed viral load; we did not observe higher unsuppressed viral load amongst those experiencing both depression and syndemic factors. Our findings point to the need to understand the unmet mental health needs of FSW living with HIV. TRIAL REGISTRATION: Clinical Trial Number: NCT03500172.

[Syndemics and non infectious diseases]. / Application du concept de syndémie en dehors des maladies infectieuses.

The concept of "syndemics" is getting more and more popularity in scientific journals, especially since the end of the first decade of the current century. It relates to the dynamic interaction of synchronous or sequential diseases (whether communicable or not, also including mental diseases), with social and environmental factors, resulting at the end in a worse global outcome. A first article in the same Journal (1) was devoted to infectious diseases, especially COVID-19 and HIV infections. In this second article, we highlight the fact that the concept is also applicable on diseases which are not transmitted by infectious pathogens. The importance of considering action within the field of social determinants of care will be illustrated by a limited selection of examples.

Le concept de «syndémie¼ - l'interaction entre maladies co-existantes ou séquentielles (transmissibles, non transmissibles, et maladies mentales), avec des phénomènes sociaux et environnementaux qui amplifient les effets négatifs de cette interaction - fait de plus en plus l'objet de publications dans des journaux internationaux, particulièrement ces dernières années. Un premier article dans cette même Revue (1) avait ciblé plus particulièrement les maladies infectieuses, en particulier les infections COVID-19 et HIV. Dans ce deuxième article, nous soulignons que le concept est aussi d'application pour des maladies non infectieuses. L'importance de la prise en charge des déterminants sociaux de la santé est illustré par quelques exemples choisis.

[From pandemic to syndemic : the importance of context]. / Face à la COVID-19. De la pandémie à la syndémie : l'importance du contexte.

The concept of "syndemics" is getting more and more popularity in scientific journals, especially since the end of the first decade of the current century. It relates to the dynamic interaction of synchronous or sequential diseases (whether communicable or not, also including mental diseases), with social and environmental factors, resulting at the end in a worse global outcome. The rise of publications in peer reviewed journals is exponential, especially in the last ten years. Born after another - forgotten - epidemy, the one related to HIV (AIDS), this concept is more than ever cited within the frame of the still ongoing COVID-19 pandemics. We will highlight this concept through a couple of selected examples related to infectious diseases. The recognition of an extensive intertwining allows to change in depth the way we approach health care efficiency, both at an individual as well as a societal level.

Le concept de «syndémie¼ - l'interaction entre maladies co-existantes ou séquentielles (transmissibles, non transmissibles, et maladies mentales), avec des phénomènes sociaux et environnementaux qui amplifient les effets négatifs de cette interaction - fait de plus en plus le sujet de publications dans des journaux internationaux, particulièrement ces dernières années. La croissance d'articles est effectivement exponentielle en particulier depuis la fin de la première décade du 21ème siècle. Né dans les suites d'une autre épidémie - celle du SIDA (taxée d'ailleurs de pandémie oubliée) - ce terme est devenu de plus en plus populaire. Il l'est encore plus aujourd'hui, depuis l'avènement de la crise sanitaire liée à une autre pandémie, celle de la COVID-19. Les liens et interactions multiples entre maladies et facteurs «externes¼ seront illustrés à l'aide de quelques exemples relatifs aux maladies infectieuses. Le fait même de reconnaître un tel entrelacement permet d'évoquer une approche différente afin d'améliorer l'efficience de la prise en charge de la santé d'une population et d'un individu.

'Those tablets, they are finding an empty stomach': a qualitative investigation of HIV risk among sexual and gender minority migrants in Cape Town, South Africa.

ABSTRACTObjectives: HIV prevalence among sexual and gender minority (SGM) individuals in South Africa is among the highest in the world; however, SGM migrants, an especially vulnerable subgroup of both the SGM and migrant populations, have frequently been overlooked in the country's robust public health response. This qualitative study, guided by syndemics theory, explored the processes by which SGM migrants in South Africa are exposed to HIV risk and those that may reduce this risk.Design: We conducted 6 focus groups with a total of 30 SGM migrants living in Cape Town. Participants were men who have sex with men, women who have sex with women, and transgender women. Transcripts were analyzed using grounded theory.Results: Participants identified a number of interrelated factors (insecure immigration status, financial and housing instability, food insecurity, stigma and discrimination, and lack of social support) contributing to HIV risk. While some took PrEP or HIV medication, adherence could be affected by structural and psychosocial barriers.Conclusion: Interventions that respond to the syndemic impacts on HIV outcomes are needed to reduce disease burden among SGM migrants in South Africa.

Syndemics of Sexually Transmitted Infections in a Sample of Racially Diverse Pregnant Young Women.

INTRODUCTION: Syndemic theory posits that poor health outcomes co-occur and amplify each other in the context of harmful conditions that must be addressed simultaneously to improve health equity. This analysis identifies perinatal syndemic factors and examine how factors are related to STI in a sample of racially diverse young pregnant women. METHODS: Pregnant participants (n = 61) ages 14-21 from racially diverse backgrounds were recruited from a prenatal clinic for an ongoing longitudinal study between October 2019-February 2020. Participants completed a tablet survey assessing pregnancy intention, psychosocial factors (e.g., depression, stress, partner violence, pregnancy history) and consented to provide access to their medical records for STI and clinical urine samples screened for tobacco and cannabis use. Latent class analysis (LCA) was used to examine probabilities of co-occurring Syndemic indicators. RESULTS: Half of the women were Black (52%) and primigravida (54%). Three classes were identified in the LCA, two of them reflecting syndemics related to STI from the medical record. The largest class was half Black (51%), with a high rate of STI (65%), and was characterized by factors including depressive symptoms (93%), stress (64%), and substance use (65% cannabis, 82% tobacco). Additionally, the class with the highest rates of STI (74%) also had higher rates of partner violence (48%), morning sickness (100%), and prenatal cannabis use (63%). CONCLUSION: Findings indicate evidence of a syndemic related to increased STI. A longitudinal evaluation of syndemics in this cohort may inform appropriately tailored intervention strategies to promote perinatal health in racially diverse young pregnant populations.

On the syndemic nature of crises: A Freeman perspective.

In this paper we draw a parallel between the insights developed within the framework of the current COVID-19 health crisis and the views and insights developed with respect to the long term environmental crisis, the implications for science, technology and innovation (STI) policy, Christopher Freeman analyzed already in the early 90's. With at the time of writing, the COVID-19 pandemic entering in many countries a third wave with a very differentiated implementation path of vaccination across rich and poor countries, drawing such a parallel remains of course a relatively speculative exercise. Nevertheless, based on the available evidence of the first wave of the pandemic, we feel confident that some lessons from the current health crisis and its parallels with the long-term environmental crisis can be drawn. The COVID-19 pandemic has also been described as a " syndemic ": a term popular in medical anthropology which marries the concept of 'synergy' with 'epidemic' and provides conceptually an interesting background for these posthumous Freeman reflections on crises. The COVID-19 crisis affects citizens in very different and disproportionate ways. It results not only in rising structural inequalities among social groups and classes, but also among generations. In the paper, we focus on the growing inequality within two particular groups: youngsters and the impact of COVID-19 on learning and the organization of education; and as mirror picture, the elderly many of whom witnessed despite strict confinement in long-term care facilities, high mortality following the COVID-19 outbreak. From a Freeman perspective, these inequality consequences of the current COVID-19 health crisis call for new social STI policies: for a new "corona version" of inclusion versus exclusion.

Syndemics & syndemogenesis in COVID-19 and rheumatic and musculoskeletal diseases: old challenges, new era.

People with rheumatic and musculoskeletal diseases (RMDs) are facing several challenges during the COVID-19 pandemic, such as poor access to regular health services and drug shortages, particularly in developing countries. COVID-19 represents a syndemic, synergistic condition that interacts with and exacerbates pre-existing diseases such as RMDs, other co-morbidities and social conditions. The emerging evidence on both biological and non-biological factors implicated in worse outcomes in people with RMDs affected by the COVID-19 pandemic, whether infected by the virus or not, calls for the need to use more novel and holistic frameworks for studying disease. In this context, the use of a syndemic framework becomes particularly relevant. We appeal for a focus on the identification of barriers and facilitators to optimal care of RMDs in the context of the COVID-19 pandemic, in order to tackle both the pandemic itself and the health inequities inherent to it.
