Association of social determinants, lifestyle, and metabolic factors with mortality in Chinese adults: A nationwide 10-year prospective cohort study

Nationwide estimates of the impact of common modifiable risk factors on mortality remain crucial. We aim to assess the influence of social determinants, lifestyle, and metabolic factors on mortality in 174,004 adults aged ≥40 years from the China Cardiometabolic Disease and Cancer Cohort (4C) Study. We reveal that 17 modifiable factors are independently associated with mortality, accounting for 64.8% of all-cause mortality, 77.4% of cardiovascular mortality, and 44.8% of cancer mortality. Low education emerges as the leading factor for both all-cause and cancer mortality, while hypertension is predominant for cardiovascular mortality. Moreover, low gross domestic product per capita and high ambient particulate matter with a diameter of <2.5μm (PM2.5) air pollution account for 7.8% and 4.3% for all-cause mortality, respectively, using a different method. Gender-specific analyses reveal distinct patterns, with women's mortality primarily associated with social determinants and men exhibiting stronger associations with lifestyle factors. Targeted health interventions are essential to mitigate mortality risks effectively in China.

Association of Social Determinants with Patient-Reported Outcomes in Patients with Cancer.

Patient-reported outcome (PRO) scores have been utilized more frequently, but the relationship of PRO scores to determinants of health and social inequities has not been widely studied. Our goal was to determine the association of PRO scores with social determinants. All patients with a new cancer diagnosis who completed a PRO survey from 2020 to 2022 were included. The PRO survey recorded scores for depression, fatigue, pain interference and physical function. Higher depression, fatigue and pain scores indicated more distress. Higher physical condition scores indicated improved functionality. A total of 1090 patients were included. Married patients had significantly better individual PRO scores for each domain. Patients who were able to use the online portal to complete their survey also had better individual scores. Male patients and non-White patients had worse pain scores than female and White patients, respectively. Patients with prostate cancer had the best scores while patients with head and neck and lung cancer had the worst scores. PRO scores varied by cancer disease site and stage. Social support may act in combination with specific patient/tumor factors to influence PRO scores. These findings present opportunities to address patient support at institutional levels.

Changes in mental health problems during the COVID-19 pandemic in Mexican youth: Insights from the Voces-19 study.

Previous research suggests that the mental health impacts of the COVID-19 pandemic were stronger during the first months of it. It has also been proposed that those impacts depended on gender and other social determinants. We aim to describe the change in prevalence of mental health problems (symptoms of common mental disorders [CMD], alcohol, and drug use) between two time periods during the pandemic, and the association of mental health problems with social determinants, in adolescents and young adults in Mexico. We conducted a repeated cross-section analysis of data from VoCes-19, an online survey in November 2020 to February 2021 and November 2021 to March 2022 (combined n = ×224,099). We assessed the change in the prevalence of mental health problems, the differences in prevalence and change in the prevalence by gender, and the association of social determinants and pandemic-related variables with mental health problems, by means of multivariate regression models. The prevalence of CMD decreased (46.0% vs. 42.4%), while the prevalence of alcohol (frequent use 8.4% vs. 10.3%) and drug use (4.6% vs. 7.7%) increased. The three conditions increased more among girls/young women and trans/queer/non-binary participants than among boys/young men. The results point to the importance of considering the gendered social context of young people. A better understanding of the social circumstances that relate with mental health is required to inform interventions for these age groups.

Association of Social Determinants and Tumor Biology With Racial Disparity in Survival From Early-Stage, Hormone-Dependent Breast Cancer

Black women with hormone receptor-positive breast cancer experience the greatest racial disparity in survival of all breast cancer subtypes. The relative contributions of social determinants of health and tumor biology to this disparity are uncertain. To determine the proportion of the Black-White disparity in breast cancer survival from estrogen receptor (ER)-positive, axillary node-negative breast cancer that is associated with adverse social determinants and high-risk tumor biology. A retrospective mediation analysis of factors associated with the racial disparity in breast cancer death for cases diagnosed between 2004 and 2015 with follow-up through 2016 was carried out using the Surveillance, Epidemiology, and End Results (SEER) Oncotype registry. The study included women in the SEER-18 registry who were aged 18 years or older at diagnosis of a first primary invasive breast cancer tumor that was axillary node-negative and ER-positive, who were Black (Black), non-Hispanic White (White), and for whom the 21-gene breast recurrence score was available. Data analysis took place between March 4, 2021, and November 15, 2022. Census tract socioeconomic disadvantage, insurance status, tumor characteristics including the recurrence score, and treatment variables. Death due to breast cancer. The analysis with 60 137 women (mean [IQR] age 58.1 [50-66] years) included 5648 (9.4%) Black women and 54 489 (90.6%) White women. With a median (IQR) follow-up time of 56 (32-86) months, the age-adjusted hazard ratio (HR) for breast cancer death among Black compared with White women was 1.82 (95% CI, 1.51-2.20). Neighborhood disadvantage and insurance status together mediated 19% of the disparity (mediated HR, 1.62; 95% CI, 1.31-2.00; P < .001) and tumor biological characteristics mediated 20% (mediated HR, 1.56; 95% CI, 1.28-1.90; P < .001). A fully adjusted model that included all covariates accounted for 44% of the racial disparity (mediated HR, 1.38; 95% CI, 1.11-1.71; P < .001). Neighborhood disadvantage mediated 8% of the racial difference in the probability of a high-risk recurrence score (P = .02). In this study, racial differences in social determinants of health and indicators of aggressive tumor biology including a genomic biomarker were equally associated with the survival disparity in early-stage, ER-positive breast cancer among US women. Future research should examine more comprehensive measures of socioecological disadvantage, molecular mechanisms underlying aggressive tumor biology among Black women, and the role of ancestry-related genetic variants.

Association of social determinants with the severity of congenital heart disease.

Congenital heart diseases are the most prevalent congenital malformations and cause greater morbi-mortality in newborns and infants. The aim of this study was to analyze the social determinants in families with children with the severity of congenital heart disease. Analytical cross-sectional study in 140 families of children with congenital heart disease to whom a structured survey was applied addressing topics related to family structure, health, economic conditions, exposure factors, and other social conditions relevant to the study, during 1 year. In all, 53.7% of the studied population belonged to low socioeconomic levels. No association was found between the severity of the heart disease and the presence of pathological antecedents in the parents. The families resided in urban areas. Also, 28.3% of the mothers had four or fewer prenatal controls during pregnancy. Only 22% of heart diseases were diagnosed during pregnancy. It was found that exposure to cigarette and wood smoke during pregnancy, in addition to low socioeconomic status, was associated with greater severity of heart disease (RACHS-1 and STS-Score), when evaluated by pathophysiological groups (cyanotic/non-cyanotic/single ventricle). Exposure to cigarette smoke, wood smoke during pregnancy, and low socioeconomic status turned out to be social determinants associated with the severity of heart disease analyzed by pathophysiological groups. The social component has not been well characterized as a cause of congenital heart disease, especially in countries like ours, where the existence of gaps and social inequities have a high impact. The findings of this study could have an impact on public health to the extent that policies are implemented to reduce exposure to cigarettes, especially during pregnancy. Knowledge of these changes and their measurement in this type of pathology could open the door to the creation of policies aimed at their prevention, focusing on the local risk factors found, which can impact the disease.

Abstract 73: Associations Of Social Determinants Of Health On Anticoagulation Treatment Among Patients With Atrial Fibrillation At Risk For Stroke At A Large Health System

Objectives: The objective of this study was to evaluate anticoagulant prescribing disparities in atrial fibrillation (AF) by exploring associations between social determinants of health (SDOH) collected from electronic health records (EHR) and oral anticoagulant (OAC) prescription. Methods: This retrospective study included adult patients newly diagnosed with AF who had ≥ 2 encounters from a large, integrated healthcare system between May 2016 and May 2021. Patient-level demographics, prescribing provider specialties, comorbidities, medications, and SDOH were extracted from EHRs. Area deprivation index (ADI) was linked to patient records as a measure of socioeconomic status. Patients were followed for 1 year from diagnosis. Multivariable logistic regression models were used to assess associations between SDOH, clinical factors, and OAC prescribing and class (warfarin or direct-acting OAC[DOAC]) of OAC prescribed. Results: Of 19,191 AF patients, 12,718 patients (66.3%) were prescribed an OAC within the first year of diagnosis. Mean age was 71.1 + 12.9 years, 43.9% (8,430 of 19,191) were females, and 91.2% (17,705 of 19,191) were white. Patients were less likely to be prescribed an OAC (relative risk [95% CI]) if they were widowed (0.98 [0.96-0.99] vs single) or had history of alcoholism (0.86 [0.79-0.95] vs no history). Most patients (53.3%) received prescriptions from a primary care provider. A linear relationship was found between worsening ADI and increased warfarin prescriptions compared with DOACs. Conclusion: Though guideline-concordant anticoagulation use remained suboptimal, clinical characteristics were strong predictors if an OAC was prescribed for AF stroke prevention. Worsening ADI was associated with an increased likelihood for patients to be prescribed warfarin instead of a DOAC.

Socio-demographic determinants of cardiovascular risk in rural population of Central India.

Raising trend of cardiovascular diseases (CVD) in developing countries created a platform for exploring the sociodemographic nexus in search of underlying cause. The precise aim of the study is to detect any possible association of social determinants and metabolic derangement with CVDs risk, particularly focusing on comparative analysis of the data to decipher the most significant factor(s), if any among the studied parameters contributing toward prediction of such cardiometabolic risk in linked with insulin resistance. In the present study, it was found that 2% of the studied population had high risk, and 13.3% had intermediate risk of developing cardiovascular events in next 10 years. Results also showed that estimated CVD risk was significantly higher in males with central obesity and age more >60 years as key determinants showing more insulin resistance at lower cut-off. This study also strongly suggests need to revise the cut-off values for HOMA index in defining insulin resistance to rural population with active the life style and need of redefining new targeted preventive health care planning.

Association of Social Determinants, Multimorbidity, and Functional Status with Mortality after Pneumonia

Social support, multimorbidity, and functional status are important determinants of health in older adults, but their prognostic implications remain unclear after an acute illness. We conducted a prospective cohort study of 201 patients 65 years or older who were hospitalized for pneumonia at a university hospital in Korea in 2019-2020. K-means cluster analysis was performed using social deprivation score (range: 0-5), activities of daily living (range: 0-7), instrumental activities of daily living (range: 0-7), physical limitation score (range: 0-7), and Gagne comorbidity index (range: 0-24) (higher scores indicate higher risk). Four groups were identified: 1) Group A: physically limited and non-disabled group with limited social support; 2) Group B: multimorbid but functional group with social support; 3) Group C: multimorbid and disabled group with social support; 4) Group D: multimorbid and disabled group with limited social support. For Groups A through D, the Kaplan-Meir estimates for 6-month mortality were 10.0%, 18.0%, 34.2%, and 43.6%, respectively, and the 6-month mean survival times were 166.4 days (95% CI: 156.1-176.6), 156.9 days (95% CI: 140.8-173.1), 145.2 days (95% CI: 126.6-163.8), and 125.9 days (95% CI: 107.7-144.1), respectively. After adjusting for sex, age, and pneumonia severity score, the hazard ratios for Groups B through D versus Group A were 2.07 (95% CI: 0.70-6.13), 3.14 (95% CI: 1.17-8.42), and 4.38 (95% CI: 1.73-11.04), respectively. Our results suggest that multimorbidity and disabilities were implicated in higher risk of 6-month mortality after pneumonia, and social support may mitigate this risk among those with multimorbidity and disability.

Association of Social Determinants, Multimorbidity, and Functional Status with Mortality after Pneumonia

Diet-related chronic diseases, such as hypertension and obesity, are prevalent in Native American (NA) communities where poor food environments are prominent and healthy food access is limited. The Chickasaw Healthy Eating Environments Research Study (CHEERS) is an NIH-funded study aimed to improve Body Mass Index and blood pressure control among NA adults with uncontrolled hypertension. This multi-level randomized trial, guided by a community-based participatory research orientation, was co-created by tribal and university partners and is implemented within the Chickasaw Nation of Oklahoma. We created hypertension-specific food boxes that contained DASH diet foods, coupons for purchasing vegetables and fruits, educational materials, and heart-healthy recipes for supporting healthy eating. Food boxes were packed and shipped monthly to intervention participants with a 30-day supply of: one fruit serving/day, one vegetable serving/day, one serving of unsalted nuts or seeds/day, one serving of beans or lentils/day, and two servings of fatty fish/week. We will present our participatory approach in co-developing the CHEERS study methods, findings with a focus on older adults, and lessons learned. CHEERS is the first innovative food box intervention to be conducted in NA communities. Food box interventions show promise in improving dietary intake and reducing hypertension and obesity in rural and poor food environments.

The Association of Distinct Social Determinants of Health with Added Sweetener Knowledge and Consumption in a U.S. Sample of People Living with HIV

Prior studies in people living with HIV (PLWH) suggest added sweetener intake exceeds recommendations and associates with cardiometabolic abnormalities. Little is known of factors that associate with increased sweetener consumption in PLWH. This cross-sectional study explored knowledge and consumption of added sweeteners and associations of social determinants of health (SDoH) among 900 PLWH residing in the United States. Demographics, SDoH, and added sweetener knowledge and consumption were assessed via an online survey, multivariable analyses were completed. Results demonstrate that sex, race, and low educational level associated with lower sweetener knowledge. Race, age, body mass index, income, limited access to fresh fruits/vegetables, and low sweetener knowledge associated with higher sweetener consumption. Findings highlight the need for consideration of specific demographics and inequitable social circumstances when developing nutrition lifestyle strategies, inclusive of added sweetener education, that are feasible and sustainable across diverse community settings of PLWH.

The role of social determinants on overall survival in advanced-stage non-small cell lung cancer patients.

e21117 Background: Non-small cell lung cancer (NSCLC) is the most prevalent form of lung cancer. Many studies have evaluated the association of social determinants with outcomes in early-stage NSCLC. These studies have shown statistically and clinically significant associations between overall survival (OS) and other social factors (e.g marital status, educational attainment). The aim of our study was to better understand the role of various social determinants of health (SDH) on OS in advanced-stage NSCLC patients in a community oncology practice in Florida. Methods: In this retrospective study, 125 patients with stage III and IV NSCLC were recruited between January 1st, 2014 until December 31st, 2018. We performed both categorical and continuous analyses (Pearson’s chi-square and Kruskal-Wallis test, respectively) to evaluate the association between median OS and several independent variables, including; gender, race, marital status, insurance status, living status, receiving financial assistance (FA), alcohol use, and smoking histories. OS is defined as the date of diagnosis up to the date of death. Other confounders that were analyzed included histology, treatment modality, comorbidities, and performance status of the patients. Results: Of the total study population (n = 125), 60% identified as male with a mean age of 73 years for the study population. The majority of patients (89%) identified as white; 56% were married, and 81% lived with someone. 66% of patients had an HMO insurance plan, and 51% of patients obtained FA to help with treatment care costs. 47% of patients identified as former smokers and 54% denied any alcohol use. The median OS for the patient population was 0.756 years. Chi-square analyses revealed that patients who received FA were more likely to live longer than median OS as opposed to patients that did not receive FA (OR = 2.41, 95% CI [1.18, 4.96], p = 0.050). Kruskal-Wallis analyses demonstrated that patients receiving FA had nearly a two-fold increase in median OS compared to patients without financial assistance (median OS = 1.01 years vs. 0.545 years, respectively; p = 0.013). However, other social determinants evaluated did not have a significant impact on relative OS in advanced-stage NSCLC. Conclusions: Ultimately, our study concludes that receiving FA has a significant association with increased OS in advanced-stage NSCLC patients. This study highlights the importance of reducing the financial burden of advanced-stage NSCLC patients and how FA impacts patient outcomes. Future prospective cohort studies with a larger sample size are warranted to identify other SDH, as well as the underlying mechanisms affecting median OS, in patients with advanced-stage NSCLC.

Associations of psychosocial factors, knowledge, attitudes and practices with hospitalizations in internal medicine divisions in different population groups in Israel

BackgroundInequalities in healthcare utilization exist across ethnic groups; however, the contributions of health-related knowledge and psychosocial factors to these inequalities remain unclear. We examined associations of social determinants of health, psychological factors, knowledge, attitudes and health practices, with hospitalizations in internal medicine divisions, among Israeli adults, Jews and Arabs, with non-communicable diseases, in a setting of universal health insurance.MethodsA retrospective study was undertaken among 520 Jews and Arabs aged 40 years or older with non-communicable diseases, members of a large health maintenance organization. Hospitalization (at least once during 2008) in an internal medicine division was determined based on documentation in electronic health records. Participants were randomly selected in strata of sex, population-group and hospitalization status (yes/no). Data were collected from medical records and via face-to-face interviews using a structured questionnaire. Main independent variables included comorbidity burden, health behaviors, mental health wellbeing and self-rated health. Scales measuring health knowledge and attitudes/beliefs were constructed using factor analysis.ResultsComorbidity burden (OR 1.41 [95% CI 1.24–1.61]) and self-rated health (not good vs. good) (OR 1.88 [95% CI 1.13–3.12]) were positively associated with hospitalizations in an internal medicine division, while an inverse association was found with better mental health wellbeing (OR 0.98 [95% CI 0.96–0.99, for each 1-point score increase). Among Jewish participants, positive associations were found of the number of offspring, comorbidity burden and perceived difficulty, with hospitalizations. No significant associations were found with hospitalizations of other sociodemographics, health behaviors, knowledge and attitudes/beliefs.ConclusionsComorbidity burden was the main risk factor of hospitalizations in internal medicine divisions. Psychosocial factors, such as self-rated health, a complex variable affected by social capital, mental wellbeing, the number of offspring, and perceived burden and difficulty, seem also to contribute. These findings suggest the involvement of broad family and social factors, beyond individual level characteristics and medical needs, in hospitalizations in internal medicine divisions. Interventions to reduce hospitalizations should be comprehensive and integrate aspects of mental health wellbeing; they should build on familial characteristics (e.g., number of offspring), factors related to social capital such as self-rated health, and perceived burden and difficulty.

Association of social determinants on well-being of rural construction workers of Central India: A cross-sectional study

Background: Social determinants of the health (SDH) arise from the social and economic condition in which they are living and their interaction produces direct impact on the health. Wider socioeconomic context, social exclusion, poverty, etc. are considered as the SDH. Objectives: This study was conducted to assess sociodemographic profile, job characteristics, and the association of the social determinants on the well-being of rural construction workers. Materials and Methods: It was cross-sectional study carried out among the rural construction workers employed at one of the medical institutes in Central India. Results: About more than half of the study participants belonged to the lower class of socioeconomic status by Modified B. G. Prasad classification 2017. Sixty-three percent participants were laborers, followed by 32% in assistance services. Musculoskeletal pain was the most common self-reported health issue, whereas near about 3/4th of study participants were found to have low or no risk on Kesseler's Distress Scale. The association between education and socioeconomic condition with well-being of rural construction workers was not found to be statistically significant. While, the association between Kesseler's Distress Scale and the presence of addiction was found to be statistically significant. Conclusion: Maximum study participants belonged to lower socioeconomic class, and musculoskeletal pain was the most common self-reported illness. The association between well-being and Kesseler's Distress Score and addiction was found to be statistically significant.

Abstract PO-155: Social determinants of receptor positive breast cancer patients’ survival in Louisiana

Abstract Breast carcinoma is the most commonly diagnosed cancer in Louisiana women. Four molecular subtypes of breast cancer are classified by the presence or lack of certain hormone receptors (HR), specifically estrogen and progesterone receptors, and the Human epidermal growth factor 2 (HER2) including: Luminal A (HR+/HER2-), Luminal B (HR+/HER2+), HER2-enriched (HR-/HER2+), and Triple-Negative Breast Cancer, TNBC (HR-/HER2-). Although it is now known that genetics has a role in the risk of breast cancer incidence, other factors such as age, race, and neighborhood also have an effect on prognosis and survival. Previously we have reported that in Louisiana neighborhood concentrated disadvantage index (CDI) explained the racial disparities in TNBC stage at diagnosis and survival, but not the disparities present in incidence. The purpose of this study is to assess the association of social determinants in Luminal A, Luminal B, and HER2-enriched breast cancers patients’ survival. This population-based study used 2010-2016 breast cancer data from the Louisiana Tumor Registry (LTR) and the data of the population at risk was obtained from the US Census. To assess neighborhood environment, CDI scores were calculated based on the PhenX Toolkit Protocol. We performed regression analysis of survival data based on the cox proportional hazard models using PHREG. A total of 21,005 breast cancer patient’s data were initially screened for the study with Luminal A (14,437), Luminal B (2,345), HER2-enriched (1,089) and TNBC (3134) diagnosis. Caucasian women (White) represented 68.5%, African women (Black) represented 30.42% and “other” race represented 1.09% of the breast cancer patients. Using Wald Chi-square tests, we compared stage of diagnosis (distant, regional) and CDI among Black and White patients of all three receptor positive breast cancers. For Luminal A, stage of diagnosis, [Distant: (Pr&amp;gt;ChiSq &amp;lt;0.0001), Hazard Ratio, HR:32.4] and Regional: (Pr&amp;gt;ChiSq &amp;lt;0.0001), HR:3.56], and race (Pr&amp;gt;ChiSq &amp;lt;0.0001, HR:1.58]) were significant, but not the CDI [(Pr&amp;gt;ChiSq: &amp;lt; 0.812), HR:1.0]. For Luminal B, stage of diagnosis, [Distant: (Pr&amp;gt;ChiSq &amp;lt;0.0001), HR:30.17] and Regional: (Pr&amp;gt;ChiSq &amp;lt;0.0001), HR:4.49], and race (Pr&amp;gt;ChiSq &amp;lt;0.0065, HR:1.62]) were significant, but not the CDI [(Pr&amp;gt;ChiSq: &amp;lt; 0.288), HR:0.91]. For HER2, stage of diagnosis, [Distant: (Pr&amp;gt;ChiSq &amp;lt;0.0001), HR:14.798] and Regional: (Pr&amp;gt;ChiSq &amp;lt;0.0001), HR:2.765], was significant, but race (Pr&amp;gt;ChiSq &amp;lt;0.254, HR:1.26]) and CDI [(Pr&amp;gt;ChiSq: &amp;lt; 0.75), HR:1.0] were not. We found significant racial difference in survival in Luminal A and Luminal B breast cancer subtypes but not in HER2-enriched subtype. However, we didn’t find any significant contribution of CDI in receptor positive breast cancer patient survival. Future studies should focus on assessing the processes by which social determinants affect receptor positive breast cancer disease progression. Citation Format: Alejandra M.

Social determinants of delivery mode in Jiangsu, China

BackgroundLess evidence exists regarding the association of social determinants and delivery mode in Jiangsu, and if the trend is influenced by the type of residence. This study aims to identify the significant social determinants of delivery mode, and also to compare the main differences in delivery mode between urban and rural areas.MethodsWe used data from the cross-sectional National Health Service Surveys conducted in Jiangsu Province in 2013. For the purposes of this study, information from women (15–64 years old) who had experienced childbirth the last 5 years were examined, and a total of 1365 participants were selected as research subjects.ResultsParticipants using vaginal delivery mode and cesarean delivery mode were found in 616 (45.1%) and 751(54.9%) participants, respectively. The proportion of women using cesarean delivery was 53.5% in rural area and 58.2% in urban area. Meanwhile, our results showed that women in middle Jiangsu were more likely to use cesarean delivery, and cesarean delivery is more prevalent among richer women. We also find that the more use of prenatal care visit, the more use of cesarean delivery.ConclusionsThis study validated the relationship between social determinants and the mode of delivery in Jiangsu province. Social determinants are contextual factors, which may vary by region and additional work is needed to fully understand these relationships globally. Further studies are needed to elucidate mechanisms and pathways across various populations, and these social determinants should be incorporated into future multi-level interventions designed to decrease the cesarean delivery rate.

District Level Analysis of Routine Immunization in Haryana State: Implications for Mission Indradhanush under Universal Immunization Programme.

Background:The immunization coverage in India is far away from satisfactory with full immunization coverage being only 62% at national level. Targeting the intensive efforts to poor performing areas and addressing the determinants of nonimmunization and dropouts offers a quick solution. In this paper, we assess the inter-district variations in Haryana state, and the association of social determinants with partial and no immunization.Methodology:This analysis is based on data collected as part of a large household survey undertaken in the state of Haryana to measure the extent of Universal Health Coverage. A multistage stratified random sampling design was used to select primary sampling units (i.e., subcenters), villages, and households. A total of 11,594 mothers with a child between 12 and 23 months were interviewed on receipt of immunization services. Determinants of nonimmunization and partial immunization were assessed using multiple logistic regression.Results:About 21% of children aged 12–23 months were partially immunized, while 4.3% children aged 12–23 months had received “no immunization.” While the coverage of full immunization was 74.7% at the state level, it varied from 95% in best performing district to 38% in poorest performing district. Odds of a partially immunized child were significantly higher in urban area (odds ratio [OR] = 1.23; 95% confidence interval [CI] = 1.1–1.38), among Muslim household (OR = 3.52; 95% CI = 3.03–4.11), children of illiterate parents (OR = 1.58; 95% CI = 1.22–2.05), and poorest quintile (OR = 1.61; 95% CI = 1.36–1.89).Conclusions:Wide interdistrict variations call for a need to consider changes in resource allocation and strengthening of the government initiatives to improve routine immunization in these districts.

Social determinants of health and retention in HIV care in a clinical cohort in Ontario, Canada

ABSTRACTContinuous HIV care supports antiretroviral therapy initiation and adherence, and prolongs survival. We investigated the association of social determinants of health (SDH) and subsequent retention in HIV care in a clinical cohort in Ontario, Canada. The Ontario HIV Treatment Network Cohort Study is a multi-site cohort of patients at 10 HIV clinics. Data were collected from medical charts, interviews, and via record linkage with the provincial public health laboratory for viral load tests. For participants interviewed in 2009, we used three-category multinomial logistic regression to identify predictors of retention in 2010–2012, defined as (1) continuous care (≥2 viral loads ≥90 days in all years; reference category); (2) discontinuous care (only 1 viral load/year in ≥1 year); and (3) a gap in care (≥1 year in 2010–2012 with no viral load). In total, 1838 participants were included. In 2010–2012, 71.7% had continuous care, 20.9% had discontinuous care, and 7.5% had a gap in care. Discontinuous care in 2009 was predictive (p < .0001) of future retention. SDH associated with discontinuous care were Indigenous ethnicity, being born in Canada, being employed, reporting hazardous drinking, and non-injection drug use. Being a heterosexual male was associated with having a gap in care, and being single and younger were associated with discontinuous care and a gap in care. Various SDH were associated with retention. Care discontinuity was highly predictive of future gaps. Targeted strategic interventions that better engage those at risk of suboptimal retention merit exploration.Abbreviations: AOR: adjusted odds ratio; ART: antiretroviral therapy; AUDIT: Alcohol Use Disorders Identification Test; CES-D: Center for Epidemiologic Studies Depression Scale; CIs: confidence intervals; HIV: human immunodeficiency virus; IQR: interquartile range; MSM: men who have sex with men; NA-ACCORD: North American AIDS Cohort Collaboration on Research and Design; OCS: Ontario HIV Treatment Network Cohort Study; OHTN: Ontario HIV Treatment Network; OR: odds ratio; PHOL: Public Health Ontario Laboratories; REB: Research Ethics Board; SDH: social determinants of health; US: United States

Association of Social Determinants With Children's Hospitals' Preventable Readmissions Performance.

Performance-measure risk adjustment is of great interest to hospital stakeholders who face substantial financial penalties from readmissions pay-for-performance (P4P) measures. Despite evidence of the association between social determinants of health (SDH) and individual patient readmission risk, the effect of risk adjusting for SDH on readmissions P4P penalties to hospitals is not well understood. To determine whether risk adjustment for commonly available SDH measures affects the readmissions-based P4P penalty status of a national cohort of children's hospitals. Retrospective cohort study of 43 free-standing children's hospitals within the Pediatric Health Information System database in the calendar year 2013. We evaluated hospital discharges from 2013 that met criteria for 3M Health Information Systems' potentially preventable readmissions measure for calendar year 2013. The analysis was conducted from July 2015 to August 2015. Two risk-adjustment models: a baseline model adjusted for severity of illness and an SDH-enhanced model that adjusted for severity of illness and the following 4 SDH variables: race, ethnicity, payer, and median household income for the patient's home zip code. Change in a hospital's potentially preventable readmissions penalty status (ie, change in whether a hospital exceeded the penalty threshold) using an observed-to-expected potentially preventable readmissions ratio of 1.0 as a penalty threshold. For the 179,400 hospital discharges from the 43 hospitals meeting inclusion criteria, median (interquartile range [IQR]) hospital-level percentages for the SDH variables were 39.2% nonwhite (n = 71,300; IQR, 28.6%-54.6%), 17.9% Hispanic (n = 32,060; IQR, 6.7%-37.0%), and 58.7% publicly insured (n = 106,116; IQR, 50.4%-67.8%). The hospital median household income for the patient's home zip code was $ 40,674 (IQR, $ 35,912-$ 46,190). When compared with the baseline model, adjustment for SDH resulted in a change in penalty status for 3 hospitals within the 15-day window (2 were no longer above the penalty threshold and 1 was newly penalized) and 5 hospitals within the 30-day window (3 were no longer above the penalty threshold and 2 were newly penalized). Risk adjustment for SDH changed hospitals' penalty status on a readmissions-based P4P measure. Without adjusting P4P measures for SDH, hospitals may receive penalties partially related to patient SDH factors beyond the quality of hospital care.
