Unmet rehabilitation needs in the first 6 months post-injury in a trauma centre population with moderate-to-severe traumatic injuries.

OBJECTIVE: To describe the needs for subacute inpatient rehabilitation and community-based healthcare services, rehabilitation, and social support in patients with moderate-to-severe traumatic injury in the first 6 months post-injury. Further, to explore associations between sociodemographic and clinical characteristics and unmet needs. DESIGN: Multicentre prospective cohort study. SUBJECTS: Of 601 persons (75% males), mean (standard deviation) age 47 (21) years, admitted to trauma centres in 2020 with moderate-to-severe injury, 501 patients responded at the 6-month follow-up and thus were included in the analyses. METHODS: Sociodemographic and injury-related characteristics were recorded at inclusion. Estimation of needs was assessed with the Rehabilitation Complexity Scale Extended-Trauma and the Needs and Provision Complexity Scale on hospital discharge. Provision of services was recorded 6 months post-injury. Multivariable logistic regressions explored associations between baseline variables and unmet inpatient rehabilitation and community-based service needs. RESULTS: In total, 20% exhibited unmet needs for subacute inpatient rehabilitation, compared with 60% for community-based services. Predictors for unmet community-based service needs included residing in less central areas, profound injury severity, severe head injury, and rehabilitation referral before returning home. CONCLUSION: Inadequate provision of healthcare and rehabilitation services, particularly in the municipalities, resulted in substantial unmet needs in the first 6 months following injury.

Direct and vicarious exposure to healthcare discrimination and erasure among transgender and gender independent individuals: Testing the indirect effect of mistrust in healthcare on utilization behaviors.

RATIONALE: Direct exposure to gender identity-related discrimination and erasure among the transgender and gender independent (TGI) population are associated with healthcare underutilization, which may further exacerbate the health disparities that exist between this population and cisgender individuals in the United States (U.S.). Although the impacts of direct exposure to healthcare discrimination and erasure may have on TGI individuals are known, exposure to such harm vicariously (i.e., through observation or report) is underexplored. OBJECTIVE: The present study examined the relationships among direct and vicarious gender identity-related healthcare discrimination and erasure exposure and past-year healthcare utilization. METHOD: Gender identity-based mistrust in healthcare was also assessed, as a mechanism through which direct and vicarious gender identity-related healthcare discrimination and erasure predict healthcare utilization behaviors among a sample (N = 385) of TGI adults in the U.S., aged 18 to 71 recruited online. RESULTS: Results indicated direct lifetime and vicarious healthcare discrimination and erasure exposure significantly predicted past-year healthcare underutilization when participants anticipated encountering gender identity-related healthcare discrimination. Mediational analyses indicated that higher levels of exposure to direct lifetime and vicarious healthcare discrimination and erasure were related to higher levels of mistrust in healthcare, through which past-year underutilization was significantly related. CONCLUSIONS: These findings are vital to informing healthcare practice and policy initiatives aimed at ensuring the barriers that deleteriously influence the accessibility of healthcare among TGI individuals are ameliorated.

Disparities between Native Americans and Whites in trajectories of functional independence and life satisfaction over the 5 years after traumatic brain injury.

PURPOSE: Traumatic brain injury (TBI) can lead to impairments in motor and cognitive function and reduced life satisfaction. TBI is one of the leading causes of death and disability worldwide and disproportionately affects Native Americans, who have the highest rates of TBI among all races in the United States and elevated likelihood for fatality and severe complications. This study investigated whether disparities in functional and life satisfaction outcomes exist longitudinally over the 5 years after complicated mild, moderate, or severe TBI between Native Americans and White individuals; it further explored which demographic and injury-related covariates account for them. RESEARCH METHOD: The current study used a subsample of the national TBI Model Systems Database of 80 demographically and injury-severity matched Native American and White pairs (total n = 160). RESULTS: A series of longitudinal hierarchical linear models found that Native Americans experienced significantly lower Functional Independence Measure Cognitive and Motor trajectories than Whites; however, life satisfaction was comparable. Native Americans had declining cognitive function over time relative to a slight increase in White individuals. This differential movement dissipated with the addition of employment status at the time of injury and type of health insurance. CONCLUSIONS: These results demonstrate a profound need to further investigate the cultural and contextual variables unique to Native Americans that underlie these differences and highlight the importance of culturally responsive treatment and rehabilitation in bridging the gap in recovery.

U.S. vs. Foreign Nativity and 10-Year Trajectories of Mental Health after Traumatic Brain Injury: A Model Systems Study.

BACKGROUND: Previous research has found racial and ethnic disparities in life satisfaction, depression, and anxiety after traumatic brain injury (TBI). However, limited studies have examined differences in these variables between U.S.- and foreign-born individuals with TBI. The purpose of this study was to examine whether differences exist in mental health outcomes between U.S.- and foreign-born individuals with TBI at 1, 2, 5, and 10 years after injury, as well as examine whether demographic and injury-related characteristics account for these differences. METHOD: Participants were 8289 individuals with TBI who identified as U.S.-born and 944 who identified as born outside the U.S. in the TBI Model Systems study. Participants completed measures of mental health outcomes at 1, 2, 5, and 10 years after injury. RESULTS: Foreign-born individuals with TBI had comparable levels of depression and anxiety trajectories to U.S.-born individuals, yet higher life satisfaction trajectories, even after controlling for demographic and injury-related variables. CONCLUSION: Rehabilitation professionals should consider in their clinical work the mechanisms that likely influence mental health outcomes among foreign-born individuals, including family-based values that increase resilience, as well as the possible under-reporting of mental health symptoms along the lines of cultural norms.

Racial/Ethnic Differences in Arrest Probability Trajectories after Traumatic Brain Injury: A Model Systems Study.

Background: Previous literature has documented racial/ethnic differences in traumatic brain injury (TBI) risk, cause, treatment, and rehabilitation. The purpose of the current study was to investigate potential racial/ethnic differences in arrest probability trajectories over the first 10 years after TBI and whether injury and sociodemographic characteristics accounted for these differences. Methods: The current study included 13,195 participants with moderate-to-severe TBI in the TBI Model Systems National Database who had arrest data from at least one follow-up time point (Years 1, 2, 5, and/or 10). A series of hierarchical linear models assessed racial/ethnic differences in trajectories of arrest probability over these 10 years post-injury and then included socio-demographic and injury-related covariates. Results: White individuals with TBI had lower arrest probability trajectories than Black and Native American individuals, and Asian individuals with TBI had lower arrest probability trajectories than White, Black, Latinx, and Native American persons. In many cases, racial/ethnic disparities persisted even when injury and sociodemographic characteristics were covaried. Conclusion: These results suggest that rehabilitation clinicians should assess for post-injury arrest risk factors such as age, sex, education, pre-injury unemployment, arrest history, and substance abuse, particularly in Black, Latinx, and Native American groups, and integrate programming to lessen post-injury arrest probability and improve overall rehabilitation outcomes.

Sleep, caregiver burden, and life satisfaction in Parkinson's disease caregivers: a multinational investigation.

PURPOSE: The primary aim of this study was to examine the pattern of associations among PD patient and caregiver sleep problems, caregiver burden, and caregiver life satisfaction. A secondary aim was to assess whether the pattern of associations differed between Mexican and U.S. caregivers. MATERIALS AND METHODS: Analyses were performed on data obtained from 253 caregivers (M age = 59.92). A composite score was produced for caregiver and patient sleep problems. The Zarit Burden Interview and Satisfaction with Life Scale measured caregiver burden and life satisfaction, respectively. A structural equation model with an invariance design was developed to examine and compare the pattern of associations. RESULTS: The model was generally invariant across U.S. and Mexican caregivers. Three significant indirect effects were found: caregiver sleep problems were negatively associated with life satisfaction via caregiver burden (p = 0.003); PD patient sleep problems were positively related to caregiver burden via caregiver sleep problems (p = 0.005) and life satisfaction via caregiver burden and caregiver sleep problems (p = 0.002). CONCLUSIONS: PD patient sleep problems were associated with caregiver sleep problems, leading to increased burden in caregivers and poorer life satisfaction. The findings highlight a potential opportunity for empirically supported sleep interventions.Implications for rehabilitationParkinson's disease is a progressive neurological condition that impacts patient and caregiver quality of life.Patient sleep problems contribute to greater caregiver burden, sleep problems, and reduced life satisfaction.The findings suggest patient and caregiver sleep may be a worthwhile target for intervention in order to reduce risk of caregiver burden and improve life satisfaction.

Exploration of Parkinson's Disease Symptomatology Subtypes From the Caregiver Perspective: Implications for Caregiver Burden, Depression, and Anxiety.

BACKGROUND: While research has demonstrated associations between Parkinson's disease (PD) severity and caregiver burden and emotional functioning, less is known about the associations between specific PD symptom patterns and caregiver functioning. OBJECTIVE: The purpose of the current study was to explore symptomatology subtypes in PD from the caregiver perspective in the U.S. and Mexico and to determine whether caregiver burden, depression, or anxiety differed by PD symptomatology subtype. METHODS: Two hundred fifty-three caregivers (M age = 59.9) completed Parts I and II of the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), the Zarit Burden Interview, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7 scales. RESULTS: Cluster analysis using domains from the MDS-UPDRS revealed 5 symptomatology subtypes: pain/motor predominant, low symptoms, severe diffuse symptoms, moderate restricted symptoms with speech/oral predominant, and mood predominant. Caregiver burden was greatest for caregivers of individuals in the severe diffuse symptom and moderate restricted symptoms with speech/oral predominant clusters. High caregiver depression and caregiver anxiety were observed in all clusters other than the low symptoms cluster. There were no site by cluster interactions, suggesting that symptom patterns contribute to caregiver functioning in similar ways in the U.S. and Mexico. CONCLUSIONS: This data-driven analysis revealed 5 symptomatology subtypes of PD from caregivers' perspectives and highlighted the need for treatments and interventions based on predominant PD symptom expression. Importance of caregiver support across various symptomatology expressions, and particularly on specialist treatment for predominant speech/oral difficulties was recommended.

Rehabilitation Needs, Service Provision, and Costs in the First Year Following Traumatic Injuries: Protocol for a Prospective Cohort Study.

BACKGROUND: Traumatic injuries, defined as physical injuries with sudden onset, are a major public health problem worldwide. There is a paucity of knowledge regarding rehabilitation needs and service provision for patients with moderate and major trauma, even if rehabilitation research on a spectrum of specific injuries is available. OBJECTIVE: This study aims to describe the prevalence of rehabilitation needs, the provided services, and functional outcomes across all age groups, levels of injury severity, and geographical regions in the first year after trauma. Direct and indirect costs of rehabilitation provision will also be assessed. The overarching aim is to better understand where to target future efforts. METHODS: This is a population-based prospective follow-up study. It encompasses patients of all ages with moderate and severe acute traumatic injury (New Injury Severity Score >9) admitted to the regional trauma centers in southeastern and northern Norway over a 1-year period (2020). Sociodemographic and injury data will be collected. Upon hospital discharge, rehabilitation physicians estimate rehabilitation needs. Rehabilitation needs are assessed by the Rehabilitation Complexity Scale Extended-Trauma (RCS E-Trauma; specialized inpatient rehabilitation), Needs and Provision Complexity Scale (NPCS; community-based rehabilitation and health care service delivery), and Family Needs Questionnaire-Pediatric Version (FNQ-P). Patients, family caregivers, or both will complete questionnaires at 6- and 12-month follow-ups, which are supplemented by telephone interviews. Data on functioning and disability, mental health, health-related quality of life measured by the EuroQol Questionnaire (EQ-5D), and needs and provision of rehabilitation and health care services are collected by validated outcome measures. Unmet needs are represented by the discrepancies between the estimates of the RCS E-Trauma and NPCS at the time of a patient's discharge and the rehabilitation services the patient has actually received. Formal service provision (including admission to inpatient- or outpatient-based rehabilitation), informal care, and associated costs will be collected. RESULTS: The project was funded in December 2018 and approved by the Regional Committee for Medical and Health Research Ethics in October 2019. Inclusion of patients began at Oslo University Hospital on January 1, 2020, and at the University Hospital of North Norway on February 1, 2020. As of February 2021, we have enrolled 612 patients, and for 286 patients the 6-month follow-up has been completed. Papers will be drafted for publication throughout 2021 and 2022. CONCLUSIONS: This study will improve our understanding of existing service provision, the gaps between needs and services, and the associated costs for treating patients with moderate and major trauma. This may guide the improvement of rehabilitation and health care resource planning and allocation. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/25980.

Racism, Mental Health, Healthcare Provider Trust, and Medication Adherence Among Black Patients in Safety-Net Primary Care.

There has been a growing research focus on social determinants to health disparities in general and medication adherence more specifically in low-income Black populations. The purpose of this study was to examine whether prior experiences of racism among Black patients in safety-net primary care indirectly predicts poor medication adherence through increased mental health symptoms and low healthcare provider trust. Two competing models were run whereby mental health leads to provider trust or provider trust leads to mental health in this multiple mediational chain. A group of 134 Black patients (76 men, average age 45.39 years) in a safety-net primary care clinic completed measures of these constructs. Results revealed that in the first model, mental health mediated the relationship between racism and provider trust, and provider trust mediated the relationship between mental health and medication adherence. All paths within this model were statistically significant, except the path between provider trust and medication adherence which approached significance. In the second model, provider trust and mental health significantly mediated the relationship between racism and medication adherence, and all direct and indirect paths were statistically significant, though the path between provider trust and medication adherence was omitted. These results may serve as catalysts to assess and attempt to mitigate specific minority-based stressors and associated outcomes within safety-net primary care settings.

Cross-cultural differences in Parkinson's disease caregiving and burden between the United States and Mexico.

INTRODUCTION: Given the rapidly aging population in both the United States and Mexico, rates of Parkinson's disease (PD) are likely to rise in both countries, suggesting that the number of individuals providing informal care will also increase, and the healthcare system will have to consider the burden this places upon caregivers. Therefore, the purpose of the current study was to examine differences in PD caregiving and burden between the United States and Mexico. METHODS: Data were collected from PD caregivers in the Parkinson's Clinic at the Hospital Civil Fray Antonio Alcalde in Guadalajara, Mexico (N = 148) and the Parkinson's and Movement Disorders Center at Virginia Commonwealth University in Richmond, Virginia (N = 105) regarding caregiver demographics and self-reported burden. RESULTS: Despite considerably more time spent in caregiving duties, higher rates in unemployment or underemployment, and lower education levels, Mexican PD caregivers reported significantly less personal strain and role strain than did their United States counterparts. Even after controlling for these and other demographic differences between the two sites, the differences in caregiver burden remained. CONCLUSIONS: Latino cultural values in Mexico encouraging the importance of caring for family members with PD and respecting elders may promote caregiving and even make it a point of cultural pride, helping to overcome potential negative effects on caregivers seen in the United States. The scientific and medical communities should view caregiving as a culturally embedded and potentially positive role, rather than predominantly as burdensome as frequently conceptualized in Western or Eurocentric cultures.

Racial/Ethnic Disparities in Longitudinal Trajectories of Community Integration After Burn Injury.

OBJECTIVES: The aim of this study was to examine potential racial/ethnic disparities in community integration for the 2 yrs after burn injury. DESIGN: A sample of 1773 adults with burn injury from the Burn Model Systems database was used with data on community integration collected at discharge (preinjury recall), 6, 12, and 24 mos after discharge. METHODS: Four sets of hierarchal linear models determined the most appropriate model for understanding racial/ethnic differences in Community Integration Questionnaire trajectories over time. RESULTS: Data indicated a decrease in community integration between discharge and 6 mos, a slight increase between 6 mos and 1 yr, and then a plateau between 1 and 2 yrs. White individuals had higher community integration score trajectories over time than black (b = 0.53, P < 0.001) and Hispanic (b = 0.58, P < 0.001) individuals, and community integration scores were similar between black and Hispanic individuals (b = -0.05, P = 0.788). These racial/ethnic disparities remained after accounting for age, sex, total burned surface area, number of days in rehabilitation, and active range of motion deficits. CONCLUSIONS: Additional rehabilitation resources should be targeted to helping black and Hispanic individuals integrate back into their communities after burn injury.

Social determinants of sleep disturbance in safety-net primary care: unmet needs, classist discrimination, and anxiety.

BACKGROUND: The 3P model proposes that predisposing, precipitating, and perpetuating factors all play a role in sleep disturbance. OBJECTIVE: The purpose of the current study is to investigate social determinants of sleep disturbance by applying the 3P model to a safety-net primary care setting, specifically by evaluating the role of classism and unmet needs as precipitating factors for sleep disturbance, and anxiety as a perpetuating factor for sleep disturbance. METHODS: Participants (N = 210) were a convenience sample of racially/ethnically diverse adults over the age of 18 (age M = 44.7 years) recruited from a safety-net primary care clinic in an urban area. The study employed a cross-sectional design. Participants completed a survey assessing sleep disturbances, anxiety, unmet needs, classism, social support, and a researcher-generated demographic form. RESULTS AND CONCLUSIONS: The unmet need for affordable long-term housing and greater experiences of classism were associated with more sleep disturbance, suggesting that both acted as precipitating factors. In a structural equation model with adequate fit indices, anxiety mediated the relationships with sleep disturbance for both the unmet need for affordable long-term housing and classism, suggesting that it serves as a perpetuating factor. Medical providers are recommended to explore these potential needs in safety-net primary care when patients present with sleep disturbance or anxiety. Assisting with connections to long-term housing and helping patients counteract and cope with classist discrimination may be effective in improving sleep in safety-net primary care.

Parkinson's Symptoms and Caregiver Burden and Mental Health: A Cross-Cultural Mediational Model.

Informal caregivers are critical in the care of individuals with Parkinson's disease (PD) and spend substantial time providing care, which may be associated with negative caregiver outcomes such as burden and mental health issues. Although research in the United States and Europe has generally supported these relations, there is very limited research on PD caregiving in Latin America. The current study examined the following connections in a sample of PD caregivers from the United States (N = 105) and Mexico (N = 148): (a) PD-related impairments (motor and nonmotor symptoms) and caregiver burden, (b) caregiver burden and caregiver mental health, and (c) PD-related impairments and mental health through caregiver burden. Study results uncovered significant relations among PD-related impairments, caregiver burden, and caregiver mental health. Further, caregiver burden fully mediated the relation between PD-related impairments and caregiver mental health at both study sites. Findings highlight a number of important intervention targets for caregivers and families, including caregiver burden and mental health.

Parkinson's family needs and caregiver mental health: A cross-cultural comparison between Mexico and the United States.

BACKGROUND/OBJECTIVE: Given the growing population of individuals with Parkinson's disease (PD) worldwide and the growing need for family members to take on a caregiving role, it is critical that cross-cultural differences be examined in order to better meet the needs of PD caregivers. The purpose of this study was to examine the connections between the unmet needs and mental health of PD caregivers differentially in Mexico and the United States. METHODS: In Parkinson's clinics at public, academic medical centers, PD caregivers from Mexico (n = 148) and the United States (n = 105) completed measures of unmet family needs and mental health. RESULTS: Caregivers in the United States had higher unmet needs for emotional support and for a community support network than caregivers in Mexico, although caregivers at the two sites had comparable levels of anxiety and depression. Unmet family needs explained 29.5% of the variance in caregiver anxiety in the United States (p < 0.001) but only 5.7% in Mexico (p = 0.209). Unmet family needs explained 30.4% of the variance in caregiver depression in the United States (p < 0.001) and 14.0% in Mexico (p = 0.001). In the United States, unmet needs for emotional support and for instrumental support uniquely predicted caregiver anxiety and depression, and in Mexico only the unmet need for instrumental support was a unique predictor. CONCLUSIONS: PD caregivers in the United States are at increased risk for poor emotional and community support, and these unmet needs channel directly into caregiver anxiety and depression. In Mexico, where caregivers have stronger emotional and community support, caregivers' unmet need for instrumental support generates anxiety and depression. Important targets for PD caregiver interventions may differ between Mexico and the United States.

Diversity and social justice in disability: The heart and soul of rehabilitation psychology.

Rehabilitation psychology uniquely incorporates a holistic, psychosocial perspective encompassing all aspects of disability, with a particular focus on the connection between disabled people and the social environment. This article introduces a special issue of Rehabilitation Psychology on diversity and social justice in disability research. The 13 articles in this special issue coalesce around the 3 themes of (a) critical disability identity theory, (b) discrimination and prejudice, and (c) health disparities in the context of disability. This article introduces each of these articles and draws upon the work contained in this special issue to highlight important future directions for research on diversity and social justice in disability across the following areas: (a) nondisabled privilege, (b) rehabilitation versus cure versus adjustment, (c) diverse modes of knowing, and (d) a priori diversity and strength-based measures. This special issue helps rehabilitation psychologists consider how they can best fulfill their social justice, human rights, and advocacy missions in order to advance access and inclusion with and for diverse groups of disabled people.

Mediational Model of Multiple Sclerosis Impairments, Family Needs, and Caregiver Mental Health in Guadalajara, Mexico.

Individuals with multiple sclerosis (MS), especially those living in Latin America, often require assistance from family caregivers throughout the duration of the disease. Previous research suggests that family caregivers may experience positive and negative outcomes from providing care to individuals with MS, but few studies have examined the unmet needs of individuals providing care to family members with MS and how these unmet needs may mediate the relationship between MS symptoms and caregiver mental health. The current study examined the relationships among MS impairments (functional, neurological, cognitive, behavioral, and emotional), unmet family needs (household, informational, financial, social support, and health), and caregiver mental health (satisfaction with life, anxiety, burden, and depression) in a sample of 81 MS caregivers from Guadalajara, Mexico. A structural equation model demonstrated the mediational effect of unmet family needs on the relationship between MS impairments and caregiver mental health. These findings suggest that intervention research on MS caregivers in Latin America may consider focusing on caregiver mental health problems by addressing unmet family needs and teaching caregivers ways to manage the impairments of the individual with MS.

Understanding the association between discrimination and depression among sexual minority people of color: Evidence for diminishing returns of socioeconomic advantage.

OBJECTIVE: To examine the differential association of heterosexism and racism on depression as moderated by socioeconomic status (SES) among sexual minority people of color. METHOD: A cross-sectional sample of sexual minority people of color (n = 170) was surveyed on their experiences of heterosexism, racism, depression, and SES in a national online study based in the United States. RESULTS: Bivariately, SES was inversely associated with depression, racism, and heterosexism. Moderation analyses found that for individuals with less socioeconomic advantage, the associations between heterosexism and depression were not as strong. However, at higher socioeconomic advantage, heterosexism was more strongly positively associated with depression. CONCLUSION: These results suggest that the effects of discrimination on depression in sexual minority individuals of color may be accentuated at higher socioeconomic levels. Implications suggest helping sexual minority clients of color from higher SES backgrounds explore the effects of discrimination on their mental health.

Measuring couple relationship quality in a rural African population: Validation of a Couple Functionality Assessment Tool in Malawi.

Available data suggest that individual and family well-being are linked to the quality of women's and men's couple relationships, but few tools exist to assess couple relationship functioning in low- and middle-income countries. In response to this gap, Catholic Relief Services has developed a Couple Functionality Assessment Tool (CFAT) to capture valid and reliable data on various domains of relationship quality. This tool is designed to be used by interventions which aim to improve couple and family well-being as a means of measuring the effectiveness of these interventions, particularly related to couple relationship quality. We carried out a validation study of the CFAT among 401 married and cohabiting adults (203 women and 198 men) in rural Chikhwawa District, Malawi. Using psychometric scales, the CFAT addressed six domains of couple relationship quality (intimacy, partner support, sexual satisfaction, gender roles, decision-making, and communication and conflict management), and included questions on intimate partner violence. We used exploratory factor analysis to assess scale performance of each domain and produce a shortened Relationship Quality Index (RQI) composed of items from five relationship quality domains. This article reports the performance of the RQI. Internal reliability and validity of the RQI were found to be good. Regression analyses examined the relationship of the RQI to outcomes important to health and development: intra-household cooperation, positive health behaviors, intimate partner violence, and gender-equitable norms. We found many significant correlations between RQI scores and these couple- and family-level development issues. There is a need to further validate the tool with use in other populations as well as to continue to explore whether the observed linkages between couple functionality and development outcomes are causal relationships.

Commentary: Reconsidering the Role of Context in Diabetes Prevention.

A substantial gap remains between what we know about type 2 diabetes prevention and our ability to apply that knowledge in socially disadvantaged populations at highest risk. This gap results, in part, from a lack of integration between epidemiologic science and social psychology theory, particularly regarding the intersections of stress, self-regulatory health behaviors, and the biological mechanisms underlying the development of diabetes. In this commentary, we describe the utility of a theoretical framework that focuses on the intersection of biological, psychosocial, and environmental contexts as they apply to diabetes disparities, and how such a framework could inform a translational research agenda to reorient prevention efforts to address these inequalities. Such reorientation is needed to ensure that the implementation of prevention efforts does not inadvertently widen diabetes disparities.
