Bridging the Evidence and Practice Gap in Chronic Kidney Disease: A System Thinking Approach to Population Health.

Chronic kidney disease (CKD) is common, costly, and life-limiting, requiring dialysis and transplantation in advanced stages. Although effective guideline-based therapy exists, the asymptomatic nature of CKD together with low health literacy, adverse social determinants of health, unmet behavioral health needs, and primary care providers' (PCP) limited understanding of CKD result in defects in screening and diagnosis. Care is fragmented between PCPs and specialty nephrologists, with limited time, expertise, and resources to address systemic gaps. In this article, the authors define how they classified defects in care and report the current numbers of patients exposed to these defects, both nationally and in their health system Accountable Care Organization. They describe use of the health system's three-pillar leadership model (believing, belonging, and building) to empower providers to transform CKD care. Believing entailed engaging individuals to believe defects in CKD care could be eliminated and were a collective responsibility. Belonging fostered the creation of learning communities that broke down silos and encouraged open communication and collaboration between PCPs and nephrologists. Building involved constructing a fractal management infrastructure with transparent reporting and shared accountability, which would enable success in innovation and transformation. The result is proactive and relational CKD care organized around the patient's needs in University Hospitals Systems of Excellence. Systems of excellence combine multiple domains of expertise to promote best practice guidelines and integrate care throughout the system. The authors further describe a preliminary pilot of the CKD System of Excellence in primary care.

Social Vulnerability and Receipt of Neoadjuvant Chemotherapy in Patients Undergoing Radical Cystectomy for Bladder Cancer.

To evaluate the association between a population-level measure of social determinants of health, the Centers for Disease Control and Prevention Social Vulnerability Index (SVI), and receipt of neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy. We queried our institutional database for patients with nonmetastatic MIBC treated with radical cystectomy between 2000 and 2022. Patients were assigned an SVI via ZIP code of residence and grouped into quintiles of SVI (i.e. least vulnerable to most vulnerable). Multivariable logistic regression was performed to evaluate the association between SVI and receipt of neoadjuvant chemotherapy, adjusting for age, race, gender, and cancer stage. A sub-analysis was performed to evaluate the association between subthemes of SVI (socioeconomic status, household composition/disability, race/ethnicity/language, and housing/transportation) and receipt of neoadjuvant chemotherapy. Of the 978 patients identified, 490 (50.1%) received neoadjuvant chemotherapy. Patients that received neoadjuvant chemotherapy had a lower SVI, were younger, and had >cT2 stage (all, p<0.05). The most vulnerable patients had lower odds of receiving neoadjuvant chemotherapy (OR 0.61, 0.39 - 0.95) compared to the least vulnerable patients. Analysis of subthemes of SVI demonstrated similar associations by socioeconomic status (OR 0.56, 0.36 - 0.86) and household composition/disability (OR 0.57, 0.33 - 0.99). Adverse social determinants of health, or social vulnerability, is associated with suboptimal and disparate utilization of neoadjuvant chemotherapy in patients with MIBC undergoing radical cystectomy. Strategies for identifying vulnerable populations may allow for more targeted interventions that would improve equity in bladder cancer care.

Exploring the relationship between school-supervised asthma therapy and social determinants of health in pediatric asthma care.

Social determinants of health (SDoH), including access to care, economic stability, neighborhood factors, and social context, strongly influence pediatric asthma outcomes. School-supervised asthma therapy (SST) is an evidence-based strategy that improves asthma outcomes, particularly for historically marginalized children, by providing support for daily medication adherence in school. However, little is known about the relationship between these programs and the adverse SDoH commonly affecting underrepresented minority and marginalized children with asthma. We examined qualitative data from interviews (n = 52) conducted between 2017 and 2020 with diverse multi-level partners involved in Asthma Link, a SST intervention. Participants included end-users (children and their parents), deliverers (school nurses and pediatric providers), and systems-level partners (e.g., insurers, legislators, and state officials). We used inductive coding to determine themes and subthemes and deductive coding using the Healthy People 2030 SDoH framework. Three themes emerged: (1) SST mitigates adverse SDoH (improves access to preventive healthcare and asthma health literacy), (2) SST benefits children experiencing specific adverse SDoH (provides a consistent medication routine to children with unstable family/housing situations) and (3) specific adverse SDoH impede SST implementation (economic instability, culture and language barriers). This study suggests an important relationship between SDoH and SST that warrants further evaluation in our future work on this community-based asthma intervention. Moreover, our findings underscore the importance of measuring SDoH in the implementation and evaluation of pediatric asthma interventions, particularly given the strong influence of these social factors on child health outcomes.

Social Factors Associated with Congenital Syphilis in Missouri.

Congenital syphilis disproportionately affects individuals impacted by adverse social determinants of health. Understanding these determinants may help facilitate holistic care. We performed a retrospective review of mother-infant dyads with potential congenital syphilis in a Missouri hospital system. Cases were classified per Centers for Disease Control and Prevention clinical scenarios. Information was collected regarding demographics, prenatal care, substance use, and other social factors. Dyads with confirmed/highly probable or possible congenital syphilis ("congenital syphilis outcomes") were compared to those with less likely/unlikely congenital syphilis ("non-congenital syphilis outcomes") using descriptive statistics. We identified 131 dyads with infant dates of birth from 12/2015-6/2022: 74 (56%) with congenital syphilis outcomes and 56 (43%) with non-congenital syphilis outcomes. Most mothers were Black/African American (n = 84, 65%) and lived in areas with high Social Vulnerability Indices. Many had inadequate prenatal care (n = 61, 47%) and/or substance use histories (n = 55, 42%). Significant associations with congenital syphilis outcomes included limited prenatal care (OR 3.01, 95% CI 1.38-6.56), no prenatal care (OR 16.08, 95% CI 1.96-132.11), substance use (OR 3.42, 95% CI 1.61-7.25), housing instability (OR 3.42, 95% CI 1.39-8.38), and justice system interactions (OR 2.29, 95% CI 1.00-5.24). Substance use correlated with prenatal care adequacy (p < 0.001). 30% of infants with congenital syphilis outcomes were taken into protective custody. Adverse social determinants of health are common in dyads impacted by congenital syphilis. Health systems should consider interdisciplinary programming to improve testing and linkage to care. Future studies should evaluate social support for congenital syphilis prevention and management.

Association of apolipoprotein B and apolipoprotein A1 levels with social determinants of health and coronary artery disease mortality in the United Kingdom Biobank - is there a need for consideration?

A higher prevalence of cardiovascular risk factors has previously been shown to be associated with adverse social determinants of health (SDoH) and to explain some of their impact on cardiovascular risk. Whether there is a relationship between lipid parameters, specifically apolipoprotein B (apoB), apolipoprotein A1 (apoA1), their ratio (apoB/apoA1), and SDoH, and whether coronary artery disease (CAD) mortality risk associated with circulating apoB and apoA1 is modified by SDoH was unclear. We investigated associations of apoA1, apoB, and apoB/apoA1 with the level of education and household income and their joint impact on CAD mortality in participants of the UK Biobank (UKB) with and without prevalent CAD at enrollment. Hazard ratios for CAD mortality were estimated after adjusting for SDoH and clinical covariates. In 292 804 participants without established CAD, apoB, and the apoB/apoA1 ratio were inversely associated with level of education and household income, whereas apoA1 was positively associated with household income. Adjustment for education level and household income coupled with the number of people living in the household did not attenuate the association between the apolipoprotein levels and incident CAD mortality rates. In a cohort of 13 826 participants with prevalent CAD, apoA1 levels were inversely associated with level of education. Higher apoB levels were only associated with greater CAD mortality risk after adjustment for risk factors. Risk estimation for CAD death through circulating apoA1 levels requires accounting for significant differences by sex. Circulating lipid parameters are associated with SDoH in individuals without CAD. CAD mortality risk estimation through apoA1 and apoB levels does not require accounting for SDoH.

Effectiveness of an eHealth intervention for reducing psychological distress and increasing COVID-19 knowledge and protective behaviors among racialized sexual and gender minority adults: A quasi-experimental study (#SafeHandsSafeHearts).

Sexual and gender minority and racialized populations experienced heightened vulnerability during the Covid-19 pandemic. Marginalization due to structural homophobia, transphobia and racism, and resulting adverse social determinants of health that contribute to health disparities among these populations, were exacerbated by the Covid-19 pandemic and public health measures to control it. We developed and tested a tailored online intervention (#SafeHandsSafeHearts) to support racialized lesbian, gay, bisexual, transgender, queer, and other persons outside of heteronormative and cisgender identities (LGBTQ+) in Toronto, Canada during the pandemic. We used a quasi-experimental pre-test post-test design to evaluate the effectiveness of a 3-session, peer-delivered eHealth intervention in reducing psychological distress and increasing Covid-19 knowledge and protective behaviors. Individuals ≥18-years-old, resident in Toronto, and self-identified as sexual or gender minority were recruited online. Depressive and anxiety symptoms, and Covid-19 knowledge and protective behaviors were assessed at baseline, 2-weeks postintervention, and 2-months follow-up. We used generalized estimating equations and zero-truncated Poisson models to evaluate the effectiveness of the intervention on the four primary outcomes. From March to November 2021, 202 participants (median age, 27 years [Interquartile range: 23-32]) were enrolled in #SafeHandsSafeHearts. Over half (54.5%, n = 110) identified as cisgender lesbian or bisexual women or women who have sex with women, 26.2% (n = 53) cisgender gay or bisexual men or men who have sex with men, and 19.3% (n = 39) transgender or nonbinary individuals. The majority (75.7%, n = 143) were Black and other racialized individuals. The intervention led to statistically significant reductions in the prevalence of clinically significant depressive (25.4% reduction, p < .01) and anxiety symptoms (16.6% reduction, p < .05), and increases in Covid-19 protective behaviors (4.9% increase, p < .05), from baseline to postintervention. We demonstrated the effectiveness of a brief, peer-delivered eHealth intervention for racialized LGBTQ+ communities in reducing psychological distress and increasing protective behaviors amid the Covid-19 pandemic. Implementation through community-based organizations by trained peer counselors supports feasibility, acceptability, and the importance of engaging racialized LGBTQ+ communities in pandemic response preparedness. This trial is registered with ClinicalTrials.gov, number NCT04870723.

Abstract PO1-10-03: Prevalence of and Factors Associated with Food Insecurity and Other Adverse Social Determinants of Health Among Breast Oncology Patients

Abstract Background: Social determinants of health (SDOH), the non-medical factors that influence health status, have a profound impact on breast cancer (BC) outcomes and contribute to survival disparities. Food insecurity (FI), defined as a lack of consistent access to adequate food resources, is a modifiable SDOH associated with treatment disruptions, medication nonadherence, and decreased quality of life. To identify at-risk patients and inform future interventions, we implemented SDOH screening of patients seen in breast oncology clinic at our urban academic medical center. Methods: Screening was conducted through an 8-item questionnaire on the electronic patient portal. The questions covered FI, housing and transportation challenges, and emergency department (ED) visits. We conducted a retrospective analysis of SDOH data collected among patients scheduled for a breast oncology appointment between 11/1/22 and 5/25/23. Any level of food hardship or concern constituted a positive FI screen. Descriptive statistics were used to determine the prevalence of FI and other SDOH, to assess differences in FI rates by age, race/ethnicity, and clinical stage, and to compare characteristics of food-insecure vs food-secure patients. We also conducted a multivariable logistic regression analysis to estimate the odds ratio (OR) and 95% confidence interval (CI) associated with sociodemographic/clinical factors and FI. Results: A total of 2,585 patients were seen in our breast oncology practice, of which 1,189 (46.0%) were screened for SDOH, including 41.2% non-Hispanic White (NHW), 9.6% non-Hispanic Black (NHB) and 21.0% Hispanic patients. Among patients who responded to each SDOH question, 15.5% (146/940) reported some level of FI; 8.7% (84/962) were unable to pay their rent or mortgage on time; for 5.8% (57/989), lack of transportation interfered with their treatment. The FI rate differed significantly by race and ethnicity: 4.5% of NHW, 15.2% of NHB, and 41.8% of Hispanic patients reported FI (p&amp;lt; 0.001). In multivariable analysis, NHB and Hispanic patients also had significantly higher odds of FI compared to NHW patients (OR=3.68, 95% CI=1.7-7.7, p&amp;lt; 0.001 for NHB and OR=15.0, 95% CI=8.8-27.1, p&amp;lt; 0.001 for Hispanic patients). Patients with metastatic disease had higher rates of FI compared to other breast oncology patients (23.6% vs 14.8%, p=0.048), and a metastatic BC diagnosis was associated with over twice the odds of FI (OR=2.18, 95% CI=1.1-4.2, p=0.02). Among food-insecure patients, 41.1% were unable to pay their rent or mortgage on time and 22.6% reported transportation difficulties interfering with treatment (vs 2.6% and 2.4%, respectively, for food-secure patients (p&amp;lt; 0.001)). Compared to food-secure patients, those who were food-insecure had significantly higher rates of self-reported ED visits in the past 12 months: 18.8% vs. 33.6% reported at least 1 ED visit, respectively, and 5.2% vs. 16.4% reported multiple ED visits, respectively (p&amp;lt; 0.001). Conclusions: In this analysis of SDOH data among patients seen in breast oncology clinic, FI was the most common social health risk reported, with nearly a quarter of patients with metastatic BC reporting FI. Racial/ethnic minorities were also at considerably higher risk for FI. ED utilization was significantly higher among food-insecure patients. Targeted interventions to reduce FI in at-risk populations are warranted to improve clinical and healthcare utilization outcomes.

Abstract PO4-09-08: Perceptions and Experiences of Black Women on Family History Sharing and Genetic Testing for Hereditary Breast and Ovarian Cancer

Abstract Black women experience significant disparities in morbidity and mortality related to hereditary breast and ovarian cancer (HBOC). Early identification of women with HBOC is essential for proactive screening and timely diagnosis. However, evidence suggests that Black women receive genetic testing for HBOC at lower rates than their White counterparts. We conducted in-depth qualitative interviews with 107 Black women with a personal or family history of breast or ovarian cancer, to understand their perceptions of their familial risk of HBOC and interest in genetic testing. In phase 1 of this study, participants were recruited from the networks of patient support organizations and historically Black sororities representing mostly highly educated and well insured patients. In phase 2, participants were recruited from a family medicine safety net clinic in Jacksonville, FL for socioeconomic diversity. Participants in both cohorts frequently expressed a lack of awareness about their family cancer history and identified many barriers to family disclosure of a cancer diagnosis. These include a culture of silence around medical issues and a belief that personal difficulties should be kept to oneself. Practical and cultural barriers to family history sharing were magnified among those with lower socioeconomic status. Many participants in both cohorts indicated a strong desire to understand their own risk of HBOC. They also expressed interested in genetic testing to proactively mitigate risk to themselves and future generations. Understanding of the potential relevance of HBOC testing to one’s personal health and post-test actionability was variable across both groups, although perceptions of genetic testing were generally favorable. These findings suggest that culturally tailored educational materials and alternative clinical modalities to collect family health history may be beneficial to improve timely identification of Black women who meet NCCN Guidelines for HBOC testing. Specifically, greater attention should be given to addressing barriers that led to underestimation of HBOC risk among patients experiencing disparities driven by adverse social determinants of health.

Multiplicative Impact of Adverse Social Determinants of Health on Outcomes in Lupus Nephritis: A Meta-analysis and Systematic Review.

Social determinants of health (SDoH) likely contribute to outcome disparities in lupus nephritis (LN). Understanding the overall burden and contribution of each domain could guide future health-equity focused interventions to improve outcomes and reduce disparities in LN. Objectives of this meta-analysis were to: 1) determine the association of overall SDoH and specific SDoH domains on LN outcomes, and 2) develop a framework for the multidimensional impact of SDoH on LN outcomes. We performed a comprehensive search of studies measuring associations between SDoH and LN outcomes. We examined pooled odds of poor LN outcomes including mortality, end-stage kidney disease, or cardiovascular disease in patients with and without adverse SDoH. Additionally, we calculated the pooled odds ratios of outcomes by four SDoH domains: individual (e.g., insurance), healthcare (e.g., fragmented care), community (e.g., neighborhood socioeconomic status), and health behaviors (e.g., smoking). Among 531 screened studies, 31 met inclusion and 13 studies with raw data were included in meta-analysis. Pooled odds of poor outcomes, were 1.47-fold higher in patients with any adverse SDoH. Patients with adverse SDoH in individual and healthcare domains had 1.64-fold and 1.77-fold higher odds of poor outcomes. We found a multiplicative impact of having ≥2 adverse SDoH on LN outcomes. Patients of Black Race with public insurance and fragmented care had 12-fold higher odds of poor LN outcomes. Adverse SDoH is associated with poor LN outcomes. Having ≥2 adverse SDoH, specifically in different SDoH domains, had a multiplicative impact leading to worse LN outcomes, widening disparities.

Access and use of mobile health applications among Medicaid-insured pregnant and postpartum individuals

Mobile health applications can address health disparities in prenatal care due to adverse social determinants of health. We assessed the uptake and use of, preferences for, and barriers to mobile health applications among Medicaid-insured pregnant and postpartum individuals enrolled in prenatal care from March to May 2021. Medicaid-insured pregnant and postpartum individuals frequently used (56 %) and were potentially interested in using (90 %) mobile health applications for health-related tasks and had reliable internet access to do so (94 %). Over two fifths (44 %) reported barriers to using mobile health applications. Further research is needed to understand whether using mobile health applications to address social needs in the peripartum period can affect prenatal care utilization and decrease health disparities.

Mitigating adverse social determinants of health in the vulnerable population: Insights from a home visitation programme

Introduction: Low-income families are exposed to adverse childhood experiences and psychosocial risks that impact child development. At the KK Women’s and Children’s Hospital in Singapore, Kids Integrated Development Service (KIDS0-3) is a home visitation programme that aims to optimise the development of children from low-income families. Method: Data comprising family demographics, maternal psychosocial risks and outcomes of child development were collated through a chart review of 469 mother-child dyads enrolled from June 2014 to October 2022. Results: Based on the Family and Adult Support Tool, 312 families (67%) were identified as moderate or high-risk. Children from moderate and high-risk families had poorer Bayley cognitive (mean 95.88 [SD 8.25] versus [vs] 98.44 [SD 8.72], P=0.014) and language scores (mean 87.38 [SD 10.35] vs 90.43 [SD 9.61], P=0.016] at 24 months of age, compared to the low-risk group. Children of teenage mothers had lower Bayley cognitive scores (mean 95.16 [SD 8.42] vs 97.76 [SD 8.55], P=0.037), and children of mothers who experienced sexual abuse had lower Bayley cognitive scores (mean 93.1 [SD 5.68] vs 99.7 [SD 8.17], P=0.013) and language scores (mean 82.3 [SD 12.87] vs 91.3 [SD 10.86], P=0.021]. Antenatal enrolment yielded better child language (mean 90.1 [SD 9.37] vs 87.13 [SD 10.79], P=0.04) and motor outcomes (mean 99.62 [SD 9.45] vs 94.72 [SD 9.51], P=0 .001) than postnatal enrolment. Conclusion: Psychosocial risks impact the development of children from low-income families in Singapore. Findings underscore the importance of early, integrated intervention for vulnerable families.

Abstract 2245: Awareness and participation in cancer-related clinical trials among gastrointestinal cancer survivors

Abstract Despite significant advances in cancer prevention, early detection, and treatment, there is a persistent disparity in cancer outcomes between diverse racial/ethnic groups and medically underserved populations in the United States (US). The underrepresentation of non-white racial/ethnic groups in clinical trials (CTs) poses a critical challenge to cancer research and effective care delivery. The Hispanic/Latino population is one of the fastest-growing ethnic groups in the US and has a high rate of gastrointestinal (GI) cancer. Although Hispanics/Latinos comprise 18.5% of the US population, they have participation rates of only 1% in CTs. We aimed to describe the awareness and participation of Hispanic/Latino GI cancer survivors in cancer-related CTs. We analyzed preliminary data from an ongoing cross-sectional study that examines the social determinants of health (SDOH) associated with participation in cancer-related CTs among GI cancer survivors. As of November 7, 2023, 57 individuals aged ≥ 21 years responded to a survey assessing their awareness and participation in CTs, and other SDOH domains. Descriptive statistics were used to describe the population, including frequencies, percentages, mean, and standard deviation. The participants’ mean age was 62.5 ± 12.3 years, and 56.1% were women. Most had more than a high school education (80.6%). Moreover, 59.7% of the participants had state-sponsored health insurance or Medicaid. Twenty-nine (50.9%) of the participants reported having heard about cancer-related CTs; however, only nine (31.0%) indicated that they knew how to participate in a cancer-related CT. Most of the participants had heard about cancer-related CTs from their doctor, nurse, or other health professionals (41.4%), their family/friends (20.7%), or social media/newspapers (20.7%). Furthermore, 13 (44.8%) had been invited to participate and 11 (84.6%) were eligible and participated in cancer-related CTs. Most of the participants who were eligible and participated in cancer-related CTs (90.9%) indicated that they participated because they knew CTs are important for the development of effective cancer treatments. Our preliminary findings show high levels of awareness among Hispanics/Latinos GI cancer survivors towards CTs; however, it is concerning that only a minority of those who were aware of CTs knew how to participate in them. More efforts are needed to assess the factors and SDOH that impact participation in cancer-related CTs among this population. Additionally, we will continue to recruit participants to assess the relationship between adverse SDOH and their willingness to participate in cancer-related CTs.

Abstract 2163: Socioeconomic status associates with epigenetic modulation of TET2: An emerging pathway in cardio-oncology

Abstract Introduction: Adverse social determinants of health (SDOH) are known to accelerate poor outcomes in cardiovascular disease (CVD) and cancer. Clonal Hematopoiesis (CH) is a mechanism implicated in these disease states, partially driven by epigenetic regulatory genes, including TET2. Yet, there is not much known about how epigenetic modulations of TET2 itself may relate to the immune system and subsequent disease development. Hypothesis: We hypothesize that socioeconomic status (SES), as a SDOH marker, relates to epigenetic modulation of TET2. Methods: 60 African American adults (93.3% female, mean age 61) with CVD risk, living in the Washington, D.C. area self-reported their SES as household income. Immune system activity was assessed via splenic activity (SpleenA) by 18FDG PET/CT. Serum cytokine levels were measured by ELISA and DNA methylation analysis evaluated the epigenetic modulations of TET2. Multivariable regression analysis adjusted for ASCVD 10-year risk score and BMI was used to examine associations. Results: Out of 33 TET2 methylation sites, we found 3 sites that were significantly related to SES. Notably, only Tet2cg09666717 (SES β=0.310, p=0.038) was also associated with SpleenA (β=-0.453, p=0.036) and several cytokines: IL-17A, IL-1β and TNFα along with trending to significance with IFN-γ (Table). Conclusion: Thus, we found that SES associates with hypomethylation of Tet2cg09666717, which further related to SpleenA and inflammatory markers. Our findings are hypothesis generating and suggest that lower SES may relate to inflammation and immune system dysregulation by the way of epigenetic modulation of TET2. These results should be examined in larger, functional studies with diverse population-based cohorts to determine the potential relationships of both SDOH and epigenetic markers in CH and cardio-oncology outcomes.

Social Risk Groups in Patients With Diabetes With Differing Eye Care Utilization and Vision Outcomes.

To evaluate whether latent class analysis on social determinants of health (SDoH) data can identify social risk groups that differ by adverse SDoH and vision outcomes in patients with diabetes. This was a prospective cohort study of adults ≥18years with diabetes who completed a SDoH survey. Latent class analysis was used to cluster patients into social risk groups. The association of social risk group and severity of diabetic retinopathy, history of lapses in diabetic retinopathy care, and visual acuity was evaluated. A total of 1006 participants were included. The three social risk groups differed by sociodemographic characteristics. The average age was 65, 60, and 54 in Groups 1, 2, and 3 respectively. Most (51%) patients in group 1 were non-Hispanic White, 66% in group 2 were non-Hispanic Black, and 80% in group 3 were Hispanic. Group 1 had the lowest burden of adverse SDoH per person (average 3.6), group 2 had 8.2, and group 3 had 10.5. In general, group 1 lacked diabetic retinopathy knowledge, group 2 had financial insecurity and difficulties with transportation, and group 3 had financial insecurity and did not have health insurance. Social risk group was associated with a history of lapses in diabetic retinopathy care, and presenting with worse vision. We identified distinct social risk groups among patients seeking care for diabetic retinopathy that differed by social needs, eye care utilization, and vision. Identifying these groups and their specific needs can help guide interventions to effectively address adverse SDoH and improve eye care utilization and vision outcomes among patients with diabetes.

Racial and Ethnic Differences in Social Determinants of Health and Health-Related Social Needs Among Adults - Behavioral Risk Factor Surveillance System, United States, 2022.

Social determinants of health (SDOH) are a broad array of social and contextual conditions where persons are born, live, learn, work, play, worship, and age that influence their physical and mental wellbeing and quality of life. Using 2022 Behavioral Risk Factor Surveillance System data, this study assessed measures of adverse SDOH and health-related social needs (HRSN) among U.S. adult populations. Measures included life satisfaction, social and emotional support, social isolation or loneliness, employment stability, food stability/security, housing stability/security, utility stability/security, transportation access, mental well-being, and health care access. Prevalence ratios were adjusted for age, sex, education, marital status, income, and self-rated health. Social isolation or loneliness (31.9%) and lack of social and emotional support (24.8%) were the most commonly reported measures, both of which were more prevalent among non-Hispanic (NH) American Indian or Alaska Native, NH Black or African American, NH Native Hawaiian or other Pacific Islander, NH multiracial, and Hispanic or Latino adults than among NH White adults. The majority of prevalence estimates for other adverse SDOH and HRSN were also higher across all other racial and ethnic groups (except for NH Asian) compared with NH White adults. SDOH and HRSN data can be used to monitor needed social and health resources in the U.S. population and help evaluate population-scale interventions.

Prenatal and Pediatric Primary Care-Based Child Obesity Prevention: Effects of Adverse Social Determinants of Health on Intervention Attendance and Impact.

Background: Adverse social determinants of health (SDoHs), specifically psychosocial stressors and material hardships, are associated with early childhood obesity. Less is known about whether adverse SDoHs modify the efficacy of early childhood obesity prevention programs. Methods: We conducted a secondary analysis of publicly insured birthing parent-child dyads with Latino backgrounds participating in a randomized controlled trial of the Starting Early Program (StEP), a child obesity prevention program beginning in pregnancy. We measured baseline adverse SDoHs categorized as psychosocial stressors (low social support, single marital status, and maternal depressive symptoms) and material hardships (food insecurity, housing disrepair, and financial difficulties) individually and cumulatively in the third trimester. Logistic regression models tested effects of adverse SDoHs on StEP attendance. We then tested whether adverse SDoHs moderated intervention impacts on weight at age 2 years. Results: We observed heterogeneous effects of adverse SDoHs on outcomes in 358 parent-child dyads. While housing disrepair decreased odds of higher attendance [adjusted odds ratio (aOR) 0.52, 95% confidence interval (CI): 0.29-0.94], high levels of psychosocial stressors doubled odds of higher attendance (aOR 2.36, 95% CI: 1.04-5.34). Similarly, while certain adverse SDoHs diminished StEP impact on weight (e.g., housing disrepair), others (e.g., high psychosocial stress) enhanced StEP impact on weight. Conclusions: Effects of adverse SDoHs on intervention outcomes depend on the specific adverse SDoH. Highest engagement and benefit occurred in those with high psychosocial stress at baseline, suggesting that StEP components may mitigate aspects of psychosocial stressors. Findings also support integration of adverse SDoH assessment into strategies to enhance obesity prevention impacts on families with material hardships. Trial Registration: This study is registered on clinicaltrials.gov: Starting Early Obesity Prevention Program (NCT01541761); https://clinicaltrials.gov/ct2/show/NCT01541761.

Adverse Social Determinants of Health and Gaps in Care Coordination Among Children.

Gaps in care coordination (CC) can have detrimental impacts on children's health. It is unclear how much adverse social determinants of health (SDoH) may affect CC gaps. We determined whether exposure to adverse SDoH is associated with experiencing more gaps in CC using a representative national sample of children. Children with inadequate or no health insurance (adjusted odds ratio [aOR] = 2.41; 95% confidence interval [CI], 2.19-2.66) and living in disadvantaged neighborhoods (aOR = 1.53; 95% CI, 1.33-1.75) have a higher likelihood of having gaps in CC, as do those with higher counts of adverse SDoH (aOR = 2.17; 95% CI, 1.85-2.53). Thus, interventions to improve CC for children should consider adverse SDoH.

Disparities in prostate cancer mortality and clinical trial availability across vulnerable populations.

24 Background: Clinical trials provide high-level evidence and test novel therapies that have significantly improved cancer outcomes. However, disparities in clinical trial participation and cancer mortality persist across race/ethnicity and vulnerable populations, notably in patients with prostate cancer (PCa). Adverse social determinants of health (SDOH) and systemic barriers may underlie these disparities. Identifying and overcoming these barriers may improve access to and representation in clinical trials, thereby promoting equitable advancement and applicability of science. For these reasons, we evaluate the association between clinical trial availability, cancer mortality, and population-level SDOH in PCa. Methods: Using custom data linkage from ClinicalTrials.gov, Surveillance Epidemiology and End Results (SEER) Registry, and the Centers for Disease Control and Prevention Social Vulnerability Index (SVI), we performed a cross-sectional analysis of county-level PCa clinical trial data, cancer incidence and mortality rates, and population-level SDOH. We included Phase 2 and Phase 3 interventional PCa clinical trials with start dates from 2007 to 2022. The total number of clinical trials over the study period was calculated per county and population-adjusted for 100,000 residents. Counties were stratified into quintiles based on SVI (i.e., least vulnerable to most vulnerable). Population-adjusted clinical trial availability, cancer incidence, and cancer mortality were compared across SVI quintiles. Multivariable logistic and linear regression analyses were performed to evaluate the association between SVI and clinical trial availability and cancer mortality, respectively. Results: The mean number of PCa trials per 100,000 residents was 25.6, with the most vulnerable counties having fewer clinical trials compared to the least vulnerable counties (mean 18.1 vs. 50.0, p&lt;0.05). Further, the most vulnerable counties had a lower PCa incidence rate per 100,000 residents (mean 393.8 vs. 411.7, p&lt;0.05), but a higher PCa mortality rate per 100,000 residents (mean 85.7 vs. 72.0, p&lt;0.05). On multivariable regression analysis, the most vulnerable counties were associated with significantly decreased odds of having any PCa clinical trial (OR 0.3, 95% CI 0.2 – 0.4) and significantly increased PCa mortality (10.8, 95% CI 7.4 – 14.3), while the presence of any PCa clinical trial was associated with significantly decreased PCa mortality (-6.9, 95% CI -9.1 – -4.7). Conclusions: The most vulnerable counties were far less likely to have any PCa clinical trials despite having a significantly higher PCa mortality rate. The presence of a PCa clinical trial was associated with a reduction in PCa mortality. These vulnerable counties represent scientifically underserved populations that may benefit from equity-driven clinical trial enrollment and cancer care infrastructure expansion.
