The need for an intersectionality framework in precision medicine research.

Precision medicine research has seen growing efforts to increase participation of communities that have been historically underrepresented in biomedical research. Marginalized racial and ethnic communities have received particular attention, toward the goal of improving the generalizability of scientific knowledge and promoting health equity. Against this backdrop, research has highlighted three key issues that could impede the promise of precision medicine research: issues surrounding (dis)trust and representation, challenges in translational efforts to improve health outcomes, and the need for responsive community engagement. Existing efforts to address these challenges have predominantly centered on single-dimensional demographic criteria such as race, ethnicity, or sex, while overlooking how these and additional variables, such as disability, gender identity, and socioeconomic factors, can confound and jointly impact research participation. We argue that increasing cohort diversity and the responsiveness of precision medicine research studies to community needs requires an approach that transcends conventional boundaries and embraces a more nuanced, multi-layered, and intersectional framework for data collection, analyses, and implementation. We draw attention to gaps in existing work, highlight how overlapping layers of marginalization might shape and substantiate one another and affect the precision-medicine research cycle, and put forth strategies to facilitate equitable advantages from precision-medicine research to diverse participants and internally heterogeneous communities.

Intersectional inequalities in science.

The US scientific workforce is primarily composed of White men. Studies have demonstrated the systemic barriers preventing women and other minoritized populations from gaining entry to science; few, however, have taken an intersectional perspective and examined the consequences of these inequalities on scientific knowledge. We provide a large-scale bibliometric analysis of the relationship between intersectional identities, topics, and scientific impact. We find homophily between identities and topic, suggesting a relationship between diversity in the scientific workforce and expansion of the knowledge base. However, topic selection comes at a cost to minoritized individuals for whom we observe both between- and within-topic citation disadvantages. To enhance the robustness of science, research organizations should provide adequate resources to historically underfunded research areas while simultaneously providing access for minoritized individuals into high-prestige networks and topics.

Intersectionality within the racial justice movement in the summer of 2020.

In an environment that is high in racial justice saliency, how do identities inform motivation for supporting specific issues in the crowd? This study examines the role that intersectionality played in mobilizing participants to join the mass demonstrations sparked by the murder of George Floyd. Building on recent studies that show how protest participants connect issue-based concerns with their identities to boost support for movements, we analyze data collected through surveys with a random sample of activists participating in the protests after George Floyd's death in Washington, DC, in 2020. We find that intersectional motivations played a significant role in mobilizing protest participants. Analysis of these factors helps explain the diversity of the crowd and provides insights into how the movement may contribute to greater success for racial justice and the degree to which the movement has staying power.

Assessing Mental Health Treatment Receipt Among Asian Adults with Limited English Proficiency Using an Intersectional Approach.

U.S. Asian adults and people with limited English proficiency (LEP) confront mental health treatment receipt disparities. At the intersection of racial and language injustice, Asian adults with LEP may face even greater disparity, but studies have not assessed this through explicitly intersectional approaches. Using 2019 and 2020 National Survey of Drug Use and Health data, we computed disparities in mental health treatment among those with mental illness comparing: Non-Hispanic (NH) Asian adults with LEP to NH White adults without LEP (joint disparity), NH Asian adults without LEP to NH White adults without LEP (referent race disparity), NH Asian adults with LEP to those without LEP (referent LEP disparity), and the joint disparity versus the sum of referent disparities (excess intersectional disparity). In age- and gender-adjusted analyses, excess intersectional disparity was 26.8% (95% CI=-29.8%-83.4%) of the joint disparity in 2019 and 63.0% (95% CI=29.1%-96.8%) in 2020. The 2019 joint disparity was 1.37 (95% CI=0.31-2.42) times that if the race-related disparity did not vary by LEP, and if LEP-related disparity did not vary by race; this figure was 2.70 (95% CI=0.23-5.17) in 2020. These findings highlight the necessity of considering the intersection of race and LEP in addressing mental health treatment disparities.

Invited Commentary: Mental health services utilization disparities at the intersection of Asian ethnoracial identity and limited English proficiency.

Nguyen et al. (Am J Epidemiol. 2024;XXX(XX):XXX-XXX) analyzed data from the U.S. National Survey of Drug Use and Health (NSDUH) to show that Asian American Native Hawaiian/Pacific Islander (AANHPI) adults with limited English proficiency have substantially lower levels of mental health services utilization compared with White adults without limited English proficiency. The findings add to the growing literature using an intersectionality framework to understand health and healthcare disparities. We comment on the authors' notable examination of intersecting minoritized identities in mental health services utilization and the welcome emphasis on AANHPI health. We discuss the limitations of the NSDUH data, which is administered in English and Spanish only, and its limited ability to support analyses disaggregated by ethnoracial subgroups. We conclude by identifying gaps related to funding, training, and data disaggregation, and highlight the role of mixed methods approaches to advance our understanding of intersectionality and health disparities research.

Racial, Ethnic, and Sex Disparities in Mental Health Among US Service Members and Veterans: Findings From the Millennium Cohort Study.

Although disparities in mental health occur within racially, ethnically, and sex-diverse civilian populations, it is unclear whether these disparities persist within US military populations. Using cross-sectional data from the Millennium Cohort Study (2014-2016; n = 103,184; 70.3% male; 75.7% non-Hispanic White), a series of logistic regression analyses were conducted to examine whether racial, ethnic, and/or sex disparities were found in mental health outcomes (posttraumatic stress disorder (PTSD), depression, anxiety, and problematic anger), hierarchically adjusting for sociodemographic, military, health-related, and social support factors. Compared with non-Hispanic White individuals, those who identified as American Indian/Alaska Native, non-Hispanic Black, Hispanic/Latino, or multiracial showed greater risk of PTSD, depression, anxiety, and problematic anger in unadjusted models. Racial and ethnic disparities in mental health were partially explained by health-related and social support factors. Women showed greater risk of depression and anxiety and lower risk of PTSD than men. Evidence of intersectionality emerged for problematic anger among Hispanic/Latino and Asian or Pacific Islander women. Overall, racial, ethnic, and sex disparities in mental health persisted among service members and veterans. Future research and interventions are recommended to reduce these disparities and improve the health and well-being of diverse service members and veterans.

An intersectional framework for counterfactual fairness in risk prediction.

Along with the increasing availability of health data has come the rise of data-driven models to inform decision making and policy. These models have the potential to benefit both patients and health care providers but can also exacerbate health inequities. Existing "algorithmic fairness" methods for measuring and correcting model bias fall short of what is needed for health policy in two key ways. First, methods typically focus on a single grouping along which discrimination may occur rather than considering multiple, intersecting groups. Second, in clinical applications, risk prediction is typically used to guide treatment, creating distinct statistical issues that invalidate most existing techniques. We present novel unfairness metrics that address both challenges. We also develop a complete framework of estimation and inference tools for our metrics, including the unfairness value ("u-value"), used to determine the relative extremity of unfairness, and standard errors and confidence intervals employing an alternative to the standard bootstrap. We demonstrate application of our framework to a COVID-19 risk prediction model deployed in a major Midwestern health system.

"Where Are You From?"-on Separation, Belonging and Imposter Syndrome as an International Medical Graduate.

Minoritized international medical graduates (IMGs) in American graduate medical education (GME) programs face a disproportionately higher number of intersectional micro- and macroaggressions. In order to create a healthier, more equitable learning environment, GME programs must make greater efforts to understand intersectionality, provide IMG trainees with additional support systems, incorporate effective bystander training, and celebrate and acknowledge the contributions of their minoritized IMG trainees.

Youth adversity and trajectories of depression/anxiety symptoms in adolescence in the context of intersectionality in the United Kingdom.

BACKGROUND: Youth adversity is associated with persistence of depression and anxiety symptoms. This association may be greater for disadvantaged societal groups (such as females) compared with advantaged groups (e.g. males). Given that persistent symptoms are observed across a range of disadvantaged, minoritized, and neurodivergent groups (e.g. low compared with high socio-economic status [SES]), the intersection of individual characteristics may be an important moderator of inequality. METHODS: Data from HeadStart Cornwall (N = 4441) was used to assess the effect of youth adversity on combined symptoms of depression and anxiety (Strengths and Difficulties Questionnaire emotional problems subscale) measured at three time-points in 11-14-year-olds. Latent trajectories and regressions were estimated for eight intersectionality profiles (based on gender, SES, and hyperactivity/inattention), and moderating effects of the individual characteristics and their intersections were estimated. RESULTS: Youth adversity was associated with higher average depression/anxiety symptoms at baseline (11-12-years) across all intersectionality profiles. The magnitude of effects differed across profiles, with suggestive evidence for a moderating effect of youth adversity on change over time in depression/anxiety symptoms attributable to the intersection between (i) gender and SES; and (ii) gender, SES, and hyperactivity/inattention. CONCLUSIONS: The detrimental effects of youth adversity pervade across intersectionality profiles. The extent to which these effects are moderated by intersectionality is discussed in terms of operational factors. The current results provide a platform for further research, which is needed to determine the importance of intersectionality as a moderator of youth adversity on the development of depression and anxiety symptoms in adolescence.

Critical decisions: A mixed-methods study of decision-making among diverse gynecologic cancer patients considering therapeutic clinical trial enrollment.

OBJECTIVE: Participation in therapeutic clinical trials does not reflect the diversity of gynecologic cancer patients, limiting access to novel therapeutics and generalizability of results. Reasons for inequities in participation among historically underrepresented populations remain undertheorized, as studies have shown equal willingness to participate among groups. We sought to apply a precarity framework to conceptualize the factors that impact patients' desire to enroll, to improve equity in gynecologic oncology clinical trial participation. METHODS: Gynecologic cancer patients at a single tertiary care facility in the Southwestern United States who discussed participation in therapeutic clinical trial with their oncology provider from 2020 to 2021 were identified. Enrolled participants completed surveys and qualitative interviews regarding treatment experiences and decision-making. Oncology providers completed parallel surveys at the time of their patient's enrollment. Descriptive statistics and thematic coding were used to analyze data. RESULTS: 30 patients were enrolled and participated in surveys and interviews. No differences were found in quantitative data assessing shared decision-making and patient-centered communication between those who enrolled and those who did not. Qualitative data demonstrated that patients who declined trial enrollment expressed concerns regarding uncertainty and loss of control, independence in decision-making, and significant resource challenges and financial toxicity of cancer treatment. CONCLUSIONS: We identified a constellation of factors that contribute to desire to enroll in clinical trials, that we describe using the framework of precarity. Through identification of precarious patients and mitigation of burdens, we anticipate improved enrollment and retention in therapeutic clinical trials among diverse gynecologic oncology patients.

Are HIV Prevention Services Reaching all LGBTQ+ Youth? An Intersectional Analysis in a National Sample.

Although research has examined disparities in HIV prevention behaviors, intersectional research is needed to understand who may be underserved. This study examines disparities in consistent condom use, HIV testing, and PrEP awareness and use across assigned sex, gender identity, sexual orientation, and racial/ethnic identity in a large sample of sexually active LGBTQ+ youth (mean age = 16.5) who completed the 2022 LGBTQ National Teen Survey. Four social identities were included as indicators in Chi-Square Automated Interaction Detection models to uncover disparate rates of HIV preventive behaviors. Generally, HIV testing and PrEP services were higher among gay/lesbian and queer youth assigned male, and lower among those assigned female. Certain LGBTQ+ youth may be systematically missed by these services, (e.g., those assigned female; those assigned male who also identify as bisexual, pansexual, asexual, questioning, or straight (and trans/gender diverse)). Providers should strive to serve populations who are not being reached by HIV prevention services.

RESUMEN: Aunque las investigaciones han examinado disparidades en los comportamientos de prevención del VIH, la aplicación de un esquema interseccional es necesario para entender quienes tienen menos acceso a los cuidados de la salud. Este estudio examina disparidides en el uso del condón, las pruebas de VIH y el conocimiento y el uso de profilaxis preexposición (PrEP) entre el sexo asignado, la identidad del género, la orientación sexual, la identidad racial/étnica) en una muestra nacional de jovenes (edad promedia = 16.5), LGBTQ+. Cuatro identidades sociales estuvieron incluidas como indicadores en el modelo de la Detección de la Interacción Automática de Chi-Square para detectar diferencias de comportamientos de prevención. Generalmente, el uso de las pruebas de VIH y los servicios de PrEP estaban mas alto entre los jovenes gay/lesbiana y queer asignados masculinos y mas bajo entre jóvenes asignadas femeninas. Es posible que ciertos jovenes LGBTQ+ estén omitidos de los servicios de las pruebas de VIH y PrEP, incluyendo jóvenes que fueron asignadas feminidas, ovenes bisexuales, pansexuales, asexuales, cuestionando, o heterosexuales (transgénero/a/e o de diversos géneros) que fueron asignados masculinos. Los profesionales de salud deben luchar para servir a las poblaciones que están fuera del alcance de los servicios preventivos del VIH.

Systems Connected to Inequities in Access to Kidney Transplantation and the Value of Intersectionality.

Patients from minoritized backgrounds based on race/ethnicity, gender, sexuality, and other social identities are more likely to experience inequities in access in kidney transplantation. Although these inequities have been reported over the decades, limited research focuses on the experiences of patients with intersecting minoritized social statuses and the mechanisms that contribute to their reduced access to transplantation. Intersectionality, a framework for understanding the ways in which multiple social identities represent interacting systems of oppression and privilege, offers a nuanced approach for understanding the experiences of patients diagnosed with end-stage organ disease with intersecting social identities. This article outlines complex systems that perpetuate inequities by highlighting the value of intersectionality in studying disparate outcomes to transplant and providing recommendations for the transplant community. This article aligns with the ESOT call for action to promote equity in transplantation worldwide.

Impact of an oral care subsidization reform on intersectional inequities in self-rated oral health in Sweden.

BACKGROUND: Oral health in Sweden is good at the population level, but seemingly with persisting or increasing inequities over the last decades. In 2008, a major Swedish reform introduced universal partial subsidies to promote preventive care and reduce the treatment cost for patients with extensive care needs. This study aimed to apply an intersectional approach to assess the impact of the 2008 subsidization reform on inequities in self-rated oral health among adults in Sweden over the period 2004-2018. METHODS: Data from 14 national surveys conducted over 2004-2018 were divided into three study periods: pre-reform (2004-2007), early post-reform (2008-2012) and late post-reform (2013-2018). The final study population was 118,650 individuals aged 24-84 years. Inequities in self-rated oral health were examined by intersectional analysis of individual heterogeneity and discriminatory accuracy across 48 intersectional strata defined by gender, age, educational level, income, and immigrant status. RESULTS: Overall, the prevalence of poor self-rated oral health decreased gradually after the reform. Gender-, education- and income-related inequities increased after the reform, but no discernible change was seen for age- or immigration-related inequities. The majority of intersectional strata experienced patterns of persistently or delayed increased inequities following the reform. CONCLUSIONS: Increased inequities in self-rated oral health were found in most intersectional strata following the reform, despite the seemingly positive oral health trends at the population level. Applying an intersectional approach might be particularly relevant for welfare states with overall good oral health outcomes but unsuccessful efforts to reduce inequities.

Discrimination, disadvantage and disempowerment during COVID-19: a qualitative intrasectional analysis of the lived experiences of an ethnically diverse healthcare workforce in the United Kingdom.

BACKGROUND: Healthcare workers (HCWs) in the United Kingdom (UK) have faced many challenges during the COVID-19 pandemic, some of these arising out of their social positions. Existing literature explicating these challenges (e.g., lack of appropriate PPE, redeployment, understaffing) have highlighted inequities in how these have been experienced by HCWs based on ethnicity, gender or, job role. In this paper, we move a step ahead and examine how the intersection of these social positions have impacted HCWs' experiences of challenges during the pandemic. METHODS: We collected qualitative data, using interviews and focus groups, from 164 HCWs from different ethnicities, gender, job roles, migration statuses, and regions in the United Kingdom (UK) between December 2020 and July 2021. Interviews and focus groups were conducted online or by telephone, and recorded with participants' permission. Recordings were transcribed and a hybrid thematic analytical approach integrating inductive data-driven codes with deductive ones informed by an intersectional framework was adopted to analyse the transcripts. RESULTS: Thematic analysis of transcripts identified disempowerment, disadvantage and, discrimination as the three main themes around which HCWs' experiences of challenges were centred, based on their intersecting identities (e.g., ethnicity gender, and/or migration status). Our analysis also acknowledges that disadvantages faced by HCWs were linked to systemic and structural factors at the micro, meso and macro ecosystemic levels. This merging of analysis which is grounded in intersectionality and considers the ecosystemic levels has been termed as 'intrasectionalism'. DISCUSSION: Our research demonstrates how an intrasectional lens can help better understand how different forms of mutually reinforcing inequities exist at all levels within the healthcare workforce and how these impact HCWs from certain backgrounds who face greater disadvantage, discrimination and disempowerment, particularly during times of crisis like the COVID-19 pandemic.

Intersectionality analysis of young people's experiences and perceptions of discrimination in primary health centers in Ebonyi State, Southeast Nigeria.

BACKGROUND: Young people (aged 10 to 24 years) in sub-Saharan Africa bear a huge and disproportionate burden of poor sexual and reproductive health (SRH) outcomes due to inequalities and discrimination in accessing sexual and reproductive health services (SRHS). This study assessed the experiences and perceptions of discrimination among young people seeking SRH services in Primary Health Centers (PHCs) using an intersectionality lens. METHODS: A cross-sectional mixed-methods study was undertaken in six local government areas (LGAs) in Ebonyi State, southeast Nigeria. The LGAs comprise both urban and rural locations. The study population for the quantitative survey consisted of 1025 randomly selected young boys and girls aged 15-24 years. Eleven focus group discussions (FGDs) were conducted with the young people. Descriptive and inferential analyses were performed for quantitative data, while thematic analysis was performed for the qualitative data, using NVivo. RESULTS: A total of 16.68% participants in the survey reported that young girls/women were treated badly/unfairly compared to young boys/men when seeking SRH services in PHCs; 15.22% reported that young clients get treated badly/unfairly from adults; and 12.49% reported that young clients with poor economic status were treated unfairly. Respondents also reported that young clients with disability (12.12%), and those who are poorly educated or uneducated (10.63%) are treated badly by healthcare providers when they access SRH services. Young people in urban areas were about 7 times more likely to believe that girls/young women are treated badly than boys/young men when seeking SRH services in PHCs compared to those who live in rural areas (p < 0.001). Among the young girls/women, residing in urban areas, being poor and in school increased the likelihood of getting treated badly/unfairly when receiving SRH services by 4 times (p < 0.001). The qualitative results revealed that health workers were generally harsh to young people seeking SRH services and the level of harshness or unfriendliness of the health workers varied depending on the young person's social identity. CONCLUSION: There are varieties of intersecting factors that contribute to the discrimination of young clients in PHCs. This underscores the urgent need to prioritize intersectional perspectives in the design and implementation of interventions that will improve access and use of SRH services by young people.

Incorporating an intersectional gender approach to improve access to maternal and child health screening services.

BACKGROUND: In the Americas, the Pan American Health Organization (PAHO) has promoted initiatives that aim at the elimination of mother-to-child transmitted diseases for over two decades. Although Guatemala has assumed the commitment to improve access and coverage of reproductive and perinatal services, the goals have not yet been reached. Often, the implementation of these efforts is hampered by complexities rooted in social, cultural, and environmental intersections. The objective of this work is to share our experience applying gender intersectionality as a methodological and analytical tool in a participatory research project that aims to improve access to maternal and child health screening services. The study shows the novel strategy that incorporates intersectionality contributing to evidence on how it can be applied to strengthen public health efforts around the implementation of the EMTCT Plus (Elimination of mother-to-child transmission of HIV, Syphilis, Hepatitis B, and Chagas disease) framework, in the mostly rural municipality of Comapa, in Guatemala. METHODS: We applied a participatory methodology, integrating theoretical and methodological frameworks to have an intersectional understanding of health services delivered by both, midwives, and the public health institution, for the prevention, diagnosis, treatment, and follow-up of HIV, Syphilis, Hepatitis B, and Chagas. The data was collected by conducting interviews, focus groups, workshops, and reviewing laboratory databases, guided by five strategies from a cultural appropriateness framework. RESULTS: The intersectional analysis shed light on the synergies and gaps of the current efforts and protocols implemented by both the midwives and the Ministry of Health. The services offered for the four diseases were often delivered independently from each other, and a comprehensive educational and communication material strategy was absent. However, our findings will be used to inform consistent, locally relevant, and culturally appropriate educational content for the local population, also following the national policy guidelines. CONCLUSIONS: Using intersectionality as a method and as an analytical tool allowed us to understand the (1) interrelation of diverse social, cultural, and environmental determinants which influence the delivery of health services, as well as (2) the dynamics between the traditional and institutional health systems. (3) Community engagement and the participation of different stakeholders in a consultative process have been fundamental for the conceptual and methodological tenets of this research. (4) Finally, giving a more prominent role to midwives can strengthen sustainability and cultural appropriateness, which is complementary to the delivery of institutional health services.

RESUMEN: ANTECEDENTES: La Organización Panamericana de la Salud (OPS) ha impulsado iniciativas que buscan la eliminación de las enfermedades de transmisión materno infantil en las Américas desde hace más de dos décadas. Si bien Guatemala ha asumido el compromiso de mejorar el acceso y la cobertura de los servicios reproductivos y perinatales, las metas aún no se han alcanzado. Muchas veces, la implementación de estos esfuerzos se ve obstaculizada por complejidades arraigadas en intersecciones sociales, culturales y ambientales. Este estudio muestra una estrategia novedosa que incorpora la interseccionalidad como un componente metodológico y analítico. Esto contribuye a evidenciar la manera en que la interseccionalidad y la participación comunitaria pueden ser aplicadas para fortalecer los esfuerzos de salud pública en torno a la implementación de la estrategia ETMI Plus (Eliminación de la transmisión materno infantil del VIH, sífilis, hepatitis B y enfermedad de Chagas), en el municipio de Comapa, en Guatemala, el cual es mayoritariamente rural. MéTODOS: Implementamos una metodología participativa, integrando marcos teóricos y metodológicos para comprender la prestación de servicios de salud, tanto por parte de comadronas como de la institución de salud pública, desde una perspectiva interseccional para la prevención, diagnóstico, tratamiento y seguimiento de VIH, sífilis, hepatitis B y Chagas. Los datos fueron recolectados a través de entrevistas, grupos focales, talleres y tras la revisión de bases de datos de laboratorio, y nos guiamos por cinco estrategias propuestas en un marco para pertinencia cultural. RESULTADOS: El análisis interseccional permitió entender las sinergias y brechas de los esfuerzos y los protocolos que se implementan actualmente, tanto por parte de las comadronas como por el Ministerio de Salud. Encontramos que los servicios que actualmente se prestan para las cuatro enfermedades son en su mayoría independientes entre sí, y no se contaba con una estrategia integral de material educativo y de comunicación. Sin embargo, nuestros resultados se utilizarán como base para una estrategia de comunicación que sea coherente, localmente relevante y culturalmente apropiada para la población local, y también siga las regulaciones de las políticas nacionales. CONCLUSIONES: El uso de la interseccionalidad como método y como herramienta analítica nos permitió comprender (1) la interrelación de diversos determinantes sociales, culturales y ambientales que influyen en la prestación de servicios de salud, así como (2) la dinámica entre los sistemas de salud tradicional e institucional. (3) El compromiso de la comunidad y la participación de las diferentes partes interesadas en un proceso consultivo han sido fundamentales para los principios conceptuales y metodológicos de esta investigación. (4) Por último, otorgar un papel más destacado a las matronas puede reforzar la sostenibilidad y la adecuación cultural, que es complementaria a la prestación de servicios de salud institucionales.

Mapping socio-geographical disparities in the occurrence of teenage maternity in Colombia using multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA).

BACKGROUND: The prevalence of teenage pregnancy in Colombia is higher than the worldwide average. The identification of socio-geographical disparities might help to prioritize public health interventions. AIM: To describe variation in the probability of teenage maternity across geopolitical departments and socio-geographical intersectional strata in Colombia. METHODS: A cross-sectional study based on live birth certificates in Colombia. Teenage maternity was defined as a woman giving birth aged 19 or younger. Multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) was applied using multilevel Poisson and logistic regression. Two different approaches were used: (1) intersectional: using strata defined by the combination of health insurance, region, area of residency, and ethnicity as the second level (2) geographical: using geopolitical departments as the second level. Null, partial, and full models were obtained. General contextual effect (GCE) based on the variance partition coefficient (VPC) was considered as the measure of disparity. Proportional change in variance (PCV) was used to identify the contribution of each variable to the between-strata variation and to identify whether this variation, if any, was due to additive or interaction effects. Residuals were used to identify strata with potential higher-order interactions. RESULTS: The prevalence of teenage mothers in Colombia was 18.30% (95% CI 18.20-18.40). The highest prevalence was observed in Vichada, 25.65% (95% CI: 23.71-27.78), and in the stratum containing mothers with Subsidized/Unaffiliated healthcare insurance, Mestizo, Rural area in the Caribbean region, 29.08% (95% CI 28.55-29.61). The VPC from the null model was 1.70% and 9.16% using the geographical and socio-geographical intersectional approaches, respectively. The higher PCV for the intersectional model was attributed to health insurance. Positive and negative interactions of effects were observed. CONCLUSION: Disparities were observed between intersectional socio-geographical strata but not between geo-political departments. Our results indicate that if resources for prevention are limited, using an intersectional socio-geographical approach would be more effective than focusing on geopolitical departments especially when focusing resources on those groups which show the highest prevalence. MAIHDA could potentially be applied to many other health outcomes where resource decisions must be made.

Action against inequalities: a synthesis of social justice & equity, diversity, inclusion frameworks.

Inequalities in health have long been recognized as interconnected with social, economic, and various other inequalities. The application of social justice and equity, diversity, inclusion (EDI) frameworks may help expand interdisciplinary perspectives in addressing inequalities. This review study conducted an environmental scan for existing syntheses of theories, models, and frameworks (TMFs) relevant to the social justice and EDI. Results from Web of Science, Scopus, PubMed, CINAHL, PsychINFO, and MEDLINE retrieved an existing implementation science framework intently centered upon health inequalities, and draws from a synthesis of postcolonial theory, reflexivity, intersectionality, structural violence, and governance theory. Given this high degree of relevance to the objective of this review, the framework was selected as a basis for expanded synthesis. Subsequent processes sought to identify social justice TMFs which could be integrated into the base framework selected, as well as to refine scope of the study. Based upon considerations of level of evidence and non-tokenistic integration, the following social justice and EDI TMFs were identified: John Rawls' theory of justice; Amartya Sen's Capabilities Approach; Iris Marion Young's theories of justice; Paulo Freire's critical consciousness; and critical race theory (CRT). The focus of the synthesis performed was scoped towards minimizing potential harms arising from actions intending to reduce inequalities. EDI considerations were not collated into a singular construct, but rather extended as a separate component assessing inequitable distribution of risks and benefits given population heterogeneity. Reflexive analysis amended the framework with two key decisions: first, the integration of environmental justice into a single construct, which helps to inform Rawls' and Sen's TMFs; second, a temporal element of sequential-analysis was employed over a unified output. The result of synthesis consists of a three-component framework which: (1) presents sixteen constructs drawn from selected TMFs, to consider various harms or potential reinforcement of existing inequalities; (2) aims to de-invisibilize marginalized groups who are noted to experience inequitable outcomes, and acknowledges the presence of individuals belonging to multiple groups; and (3) synthesizes seven considerations related to equitable dissemination and evaluation as drawn from TMFs, separated for sequential analysis after assessment of harms.

Using an intersectionality lens to explore barriers and enablers to hepatitis C point-of-care testing: a qualitative study among people who inject drugs and service providers.

BACKGROUND: Hepatitis C virus (HCV) infection is a significant global health burden, particularly among people who inject drugs. Rapid point-of-care HCV testing has emerged as a promising approach to improve HCV detection and linkage to care in harm reduction organizations such as needle and syringe programs. The objective of this study was to use an intersectionality lens to explore the barriers and enablers to point-of-care HCV testing in a needle and syringe program. METHODS: A qualitative study was conducted using semi-structured interviews with clients (people who inject drugs) and service providers in a large community organization focused on the prevention of sexually transmitted and blood borne infections and harm reduction in Montreal, Canada. An intersectionality lens was used alongside the Theoretical Domains Framework to guide the formulation of research questions as well as data collection, analysis, and interpretation. RESULTS: We interviewed 27 participants (15 clients, 12 providers). For clients, four themes emerged: (1) understanding and perceptions of HCV testing, (2) the role of an accessible and inclusive environment, (3) the interplay of emotions and motivations in decision-making, and (4) the impact of intersectional stigma related to HCV, behaviors, and identities. For providers, five themes emerged: (1) knowledge, skills, and confidence for HCV testing, (2) professional roles and their intersection with identity and lived experience, (3) resources and integration of services, (4) social and emotional factors, and (5) behavioral regulation and incentives for HCV testing. Intersectional stigma amplified access, emotional and informational barriers to HCV care for clients. In contrast, identity and lived experience acted as powerful enablers for providers in the provision of HCV care. CONCLUSION: The application of an intersectionality lens provides a nuanced understanding of multilevel barriers and enablers to point-of-care HCV testing. Findings underscore the need for tailored strategies that address stigma, improve provider roles and communication, and foster an inclusive environment for equitable HCV care. Using an intersectionality lens in implementation research can offer valuable insights, guiding the design of equity-focused implementation strategies.

Opportunities for incorporating intersectionality into biomedical informatics.

Many approaches in biomedical informatics (BMI) rely on the ability to define, gather, and manipulate biomedical data to support health through a cyclical research-practice lifecycle. Researchers within this field are often fortunate to work closely with healthcare and public health systems to influence data generation and capture and have access to a vast amount of biomedical data. Many informaticists also have the expertise to engage with stakeholders, develop new methods and applications, and influence policy. However, research and policy that explicitly seeks to address the systemic drivers of health would more effectively support health. Intersectionality is a theoretical framework that can facilitate such research. It holds that individual human experiences reflect larger socio-structural level systems of privilege and oppression, and cannot be truly understood if these systems are examined in isolation. Intersectionality explicitly accounts for the interrelated nature of systems of privilege and oppression, providing a lens through which to examine and challenge inequities. In this paper, we propose intersectionality as an intervention into how we conduct BMI research. We begin by discussing intersectionality's history and core principles as they apply to BMI. We then elaborate on the potential for intersectionality to stimulate BMI research. Specifically, we posit that our efforts in BMI to improve health should address intersectionality's five key considerations: (1) systems of privilege and oppression that shape health; (2) the interrelated nature of upstream health drivers; (3) the nuances of health outcomes within groups; (4) the problematic and power-laden nature of categories that we assign to people in research and in society; and (5) research to inform and support social change.
