Medication Adherence-From Measurer to Measured.

This essay by a researcher who developed a widely used medication adherence measure explores his experience with being labeled "nonadherent.".

Associations between Missed Colonoscopy Appointments and Multiple Prior Adherence Behaviors in an Integrated Healthcare System: An Observational Study.

BACKGROUND: Missed colonoscopy appointments delay screening and treatment for gastrointestinal disorders. Prior nonadherence with other care components may be associated with missed colonoscopy appointments. OBJECTIVE: To assess variability in prior adherence behaviors and their association with missed colonoscopy appointments. DESIGN: Retrospective cohort study. PARTICIPANTS: Patients scheduled for colonoscopy in an integrated healthcare system between January 2016 and December 2018. MAIN MEASURES: Prior adherence behaviors included: any missed outpatient appointment in the previous year; any missed gastroenterology clinic or colonoscopy appointment in the previous 2 years; and not obtaining a bowel preparation kit pre-colonoscopy. Other sociodemographic, clinical, and system characteristics were included in a multivariable model to identify independent associations between prior adherence behaviors and missed colonoscopy appointments. KEY RESULTS: The median age of the 57,590 participants was 61 years; 52.8% were female and 73.4% were white. Of 77,684 colonoscopy appointments, 3,237 (4.2%) were missed. Individuals who missed colonoscopy appointments were more likely to have missed a previous primary care appointment (62.5% vs. 38.4%), a prior gastroenterology appointment (18.4% vs. 4.7%) or not to have picked up a bowel preparation kit (42.4% vs. 17.2%), all p < 0.001. Correlations between the three adherence measures were weak (phi < 0.26). The rate of missed colonoscopy appointments increased from 1.8/100 among individuals who were adherent with all three prior care components to 24.6/100 among those who were nonadherent with all three care components. All adherence variables remained independently associated with nonadherence with colonoscopy in a multivariable model that included other covariates; adjusted odds ratios (with 95% confidence intervals) were 1.6 (1.5-1.8) for outpatient appointments, 1.9 (1.7-2.1) for gastroenterology appointments, and 3.1 (2.9-3.4) for adherence with bowel preparation kits, respectively. CONCLUSIONS: Three prior adherence behaviors were independently associated with missed colonoscopy appointments. Studies to predict adherence should use multiple, complementary measures of prior adherence when available.

Assessment of a Peer Support Group Intervention for Undocumented Latinx Immigrants With Kidney Failure.

Importance: Most undocumented immigrants with kidney failure rely on emergency dialysis (defined as dialysis after a patient presents as critically ill) and experience significant depression and anxiety and high mortality. Culturally and language-concordant peer support group interventions may be associated with reduced depression and anxiety and may provide emotional support. Objective: To investigate the feasibility and acceptability of a single-group peer support group intervention. Design, setting, and participants: This qualitative and single-group prospective study for undocumented immigrants with kidney failure receiving emergency dialysis was conducted in Denver, Colorado, from December 2017 to July 2018. The 6-month intervention included peer support group meetings in the hospital while participants were hospitalized for emergency dialysis. Data were analyzed from March to June 2022. Main outcomes and measures: To assess feasibility, the recruitment, retention, implementation, and delivery for the intervention were tracked. To measure acceptability, interviews were conducted with participants using a structured format. To assess the value of the peer support group intervention, themes and subthemes were identified from interviews with participants and group meetings. Results: Of 27 undocumented immigrants with kidney failure receiving emergency dialysis, 23 participants (9 females [39.1%] and 14 males [60.9%]; mean [SD] age, 47 [8] years) agreed to participate (recruitment rate, 85.2%). Among them, 5 individuals withdrew and did not attend meetings and 18 participants (retention rate, 78.3%) attended a mean of 6 of 12 meetings (50.0%). From interviews and meetings, 3 themes, with associated subthemes, were identified: camaraderie and emotional support from peers (subthemes: peer support is vital for people newly diagnosed with kidney failure, safe space to build relationships and share hardship with peers, hospital setting for peer support is ideal, solidarity to survive and change policy, and sustainability of the peer support group), solutions to improve care and resilience (subthemes: self-advocacy, self-motivation and optimism, kidney disease education, emotional support from peers caregivers, and faith), and emotional and physical aspects of receiving emergency dialysis (subthemes: psychosocial and physical distress, mixed experiences with language-concordant care, emotional exhaustion from end-of-life conversations, and gratitude for clinicians). Conclusions and relevance: This study found that peer support group intervention achieved feasibility and acceptability. The findings suggest that a peer support group may be a patient-centered strategy to build camaraderie and provide emotional support in kidney failure, especially for socially marginalized uninsured populations who report limited English proficiency.

Participant perspectives on the impact of receiving medically tailored meals on post-hospitalization.

OBJECTIVE: The objective of this program evaluation was to measure the impact of a medically tailored meals (MTM) intervention on participants' self-reported recovery and satisfaction while recovering from a recent hospitalization. DESIGN: A qualitative design was employed using a brief survey among all participants at the end of the intervention and phone interviews with a subset of participants. SAMPLE: Participants in this study were recently discharged from the hospital and were members of (redacted for review) who had received 2-4 weeks of MTM. MEASUREMENTS: The survey assessed overall satisfaction with the meals and perceived impact on their recovery after hospitalization (81% response rate). Interview questions asked how they felt the meals may have helped while recovering (e.g., helped them financially or with their ability to remain independent). RESULTS: Among survey participants, 65% were extremely or very satisfied with their meals. Reasons that MTM were helpful while they were recovering included having sufficient food to eat, having healthy food to eat, the convenience of the meals, and ease of preparing the meals. CONCLUSIONS: Participants receiving MTM were generally very satisfied with the program. Including nutrition education and more flexibility in quantity and frequency of food may improve satisfaction and consumption of food.

Patient Pill Organization Strategies and Adherence Measured in a Cross-Sectional Study of Hypertension.

Background: The strategies patients use to organize medications (eg, pill dispenser) may be reflected in adherence measured at follow-up. We studied whether medication organization strategies patients use at home are associated with adherence measured using pharmacy-fills, self-report, and pill counts. Design: Secondary analysis of data from a prospective randomized clinical trial. Setting: Eleven US safety-net and community primary care clinics. Patients: Of the 960 enrolled self-identified non-Hispanic Black and White patients prescribed antihypertensive medications, 731 patients reported pill organization strategies and were included. Variable: Patients were asked if they use any of the following medication organization strategies: finish previous refills first; use a pill dispenser; combine same prescriptions; or combine dissimilar prescriptions. Outcomes: Adherence to antihypertensive medications using pill counts (range, 0.0-1.0% of the days covered), pharmacy-fill (proportion of days covered >90%), and self-report (adherent/non-adherent). Results: Of the 731 participants, 38.3% were men, 51.7% were age ≥65, 52.9% self-identified as Black or African American. Of the strategies studied, 51.7% finished previous refills first, 46.5% used a pill dispenser, 38.2% combined same prescriptions and 6.0% combined dissimilar prescriptions. Median (IQR) pill count adherence was 0.65 (0.40-0.87), pharmacy-fill adherence was 75.7%, and self-reported adherence was 63.2%. Those who combined same prescriptions had significantly lower measured pill count adherence than those who did not (0.56 (0.26-0.82) vs 0.70 (0.46-0.90), p<0.01) with no significant difference in pharmacy-fill (78.1% vs 74%, p=0.22) or self-reported adherence (63.0% vs 63.3%, p=0.93). Conclusion: Self-reported medication organization strategies were common. Combining same prescriptions was associated with lower adherence as measured using pill counts but not pharmacy-fills or self-report. Clinicians and researchers should identify the pill organization strategies used by their patients to understand how these strategies may influence measures of patient adherence.

Comparing two durations of medically tailored meals posthospitalization: A randomized clinical trial.

BACKGROUND: Medically tailored meals (MTM) may be beneficial to patients after hospital discharge. OBJECTIVE: To determine if 2 versus 4 weeks of MTM posthospitalization will improve patient outcomes. DESIGN: Randomized unblinded trial. SETTINGS AND PARTICIPANTS: Six hundred and fifty patients pending hospital discharge with at least one chronic condition. INTERVENTION: One MTM a day for 2 versus 4 weeks. MAIN OUTCOME AND MEASURES: The primary outcome was a change from baseline to 60 days in the Hospital Anxiety Depression Scale (HADS). Secondary outcomes measured change in the Katz activities of daily living (ADLs), DETERMINE nutritional risk, and all-cause emergency department (ED) visits and rehospitalizations. RESULTS: From baseline to 60 days the HADS anxiety subscale changed 5.4-4.9 in the 2-week group (p = .03) and 5.4-5.3 in the 4-week group (p = .49); the difference in change between groups 0.4 (p = .25). HADS changed 5.4-4.8 in the 2-week group (p = .005) and 5.3-5.1 in the 4-week group (p = .34); the difference in change between groups 0.4 (p = .18). ADL score changed from 5.3 to 5.6 in the 2-week group (p ≤ .0001) and 5.2-5.5 in the 4-week group (p ≤ .0001); the difference in change between groups -0.01 (p = .90). The DETERMINE changed in the 2-week group from 7.2 to 6.4 (p = .0006) and from 7 to 6.7 in the 4-week group (p = .19); the difference in change between groups 0.5 (p = .13). There was no difference in ED visits and rehospitalizations between groups or time to rehospitalization. CONCLUSIONS: Different durations of short-term MTM did not affect patient-centered or utilization outcomes.

Evaluating the Role of System-Generated Communications in Health Care Organizations.

This Viewpoint discusses measures to improve the role of system-generated communications in health care organizations.

Hypertension care during the COVID-19 pandemic in an integrated health care system.

Retention in hypertension care, medication adherence, and blood pressure (BP) may have been affected by the COVID-19 pandemic. In a retrospective cohort study of 64 766 individuals with treated hypertension from an integrated health care system, we compared hypertension care during the year pre-COVID-19 (March 2019-February 2020) and the first year of COVID-19 (March 2020-February 2021). Retention in hypertension care was defined as receiving clinical BP measurements during COVID-19. Medication adherence was measured using prescription refills. Clinical care was assessed by in-person and virtual visits and changes in systolic and diastolic BP. The cohort had a mean age of 67.8 (12.2) years, 51.2% were women, and 73.5% were White. In 60 757 individuals with BP measurements pre-COVID-19, 16618 (27.4%) had no BP measurements during COVID-19. Medication adherence declined from 86.0% to 80.8% (p < .001). In-person primary care visits decreased from 2.7 (2.7) to 1.4 (1.9) per year, while virtual contacts increased from 9.5 (12.2) to 11.2 (14.2) per year (both p < .001). Among individuals with BP measurements, mean (SD) systolic BP was 126.5 mm Hg (11.8) pre-COVID-19 and 127.3 mm Hg (12.6) during COVID-19 (p = .14). Mean diastolic BP was 73.5 mm Hg (8.5) pre-COVID-19 and 73.5 mm Hg (8.7) during COVID-19 (p = .77). Even in this integrated health care system, many individuals did not receive clinical BP monitoring during COVID-19. Most individuals who remained in care maintained pre-COVID BP. Targeted outreach may be necessary to restore care continuity and hypertension control at the population level.

Early Peanut Introduction in Primary Care: Evaluation of a Multicomponent Intervention.

OBJECTIVE: To determine whether a multicomponent intervention focused on early peanut introduction was associated with a lower peanut allergy incidence in young children. METHODS: The study cohort comprised all children born January 1, 2013 through December 31, 2018 receiving care at a large health care organization. Intervention activities occurred over 16 months and included provider educational programs, electronic health record tools, and new patient instructions. We used an interrupted time series design to assess whether peanut allergy incidence differed across 3 time periods (preintervention, interim, postintervention) among high- and low-risk children. The primary outcome was incident peanut allergy by age 24 months, defined as peanut allergy in the allergy field or active problem list plus a positive supportive test. Severe eczema and/or egg allergy presence defined high-risk. Because the study was conducted as part of routine care, it was not feasible to measure what counseling clinicians provided, or how and when parents fed their children peanut-containing foods. RESULTS: In a cohort of 22,571 children, the percent with peanut allergy by age 24 months was 17.3% (116 of 671) among high-risk and 0.8% (181 of 21,900) among low-risk children. In multivariate analyses, the adjusted peanut allergy rate per 100 person-years was not significantly different across study periods among high-risk (9.6 preintervention, 11.7 interim, and 9.9 postintervention, P = .70) or low-risk (0.5 preintervention, 0.7 interim, and 0.5 postintervention, P = .17) children. CONCLUSIONS: In a community-based setting, the incidence of peanut allergy did not decline following a multicomponent intervention focused on early peanut introduction.

Sources of Clinician Burnout in Providing Care for Underserved Patients in a Safety-Net Healthcare System.

BACKGROUND: Burnout among clinicians is common and can undermine quality of care, patient outcomes, and workforce preservation, but sources of burnout or protective factors unique to clinicians working in safety-net settings are less well understood. Understanding these clinician experiences may inform interventions to reduce burnout. OBJECTIVE: To describe clinician perspectives on sources of burnout in a safety-net healthcare system. DESIGN: Semi-structured interviews were conducted with clinicians from multiple disciplines who provided care at a safety-net healthcare system from October 2018 to January 2019. Transcripts were analyzed using thematic analysis. PARTICIPANTS: Forty clinicians (25 female and 15 male; mean [SD] age, 41 [9.1]) participated, including physicians, social workers, advanced practice providers, nurses, psychologists, physical and occupational therapists, and other healthcare professionals. MAIN OUTCOMES AND MEASURES: Themes and subthemes that reflected clinician experiences, burnout, and workload expectations. KEY RESULTS: Five themes emerged: limited resources (entrenched social injustices, brokenness of the US healthcare system, precarious discharge options, and "revolving door" readmissions), barriers to building trust with patients (chasm of communication, addressing fear and mistrust, and being exposed to threats), administrative requirements (criticism hampering meaningful care, assuming extra workloads, bureaucratic burden), compassion fatigue (confronting traumatic situations, persistent worry about patient safety and welfare, witnessing mistreatment and stigmatization, overextending and overinvesting, withdrawing and shutting down, blaming self and career crisis), and advocacy as a counterbalance to burnout (solidarity when helping underserved communities, fervent advocacy, and patient gratitude). CONCLUSIONS: Among clinicians who provide care in a safety-net healthcare system, sources of burnout included limited resources, barriers to building trust with patients, administrative requirements, and compassion fatigue, but clinicians remained driven by their desire to advocate for patients. Policy-level interventions which increase funding to safety-net healthcare systems to bolster existing resources and staffing, create peer-support and wellness programs, and support advocacy efforts may mitigate burnout.

Racial and Ethnic Equity in Care for Hypertension and Diabetes in an Urban Indian Health Organization.

Approximately 70% of American Indian/Alaska Native (AI/AN) individuals reside in urban areas. Urban Indian Health Organizations (UIHOs) provide culturally engaged primary care for AI/AN patients and members of other racial and ethnic groups who have experienced disparities in diabetes and hypertension care, and are commonly affected by social and economic barriers to care. We assessed whether disparities were present between the racial and ethnic groups served by the largest UIHO in the USA. We developed retrospective cohorts of patients with hypertension or diabetes receiving primary care from this UIHO, measuring differences between AI/AN, Spanish-preferring Latinx, English-preferring Latinx, Black, and White patients in mean systolic blood pressure (SBP) and mean hemoglobin A1c (A1c) as primary outcomes. To assess processes of care, we also compared visit intensity, missed visits, and medication treatment intensity in regression models adjusted for sociodemographic and clinical characteristics. For hypertension (n = 2148), adjusted mean SBP ranged from 135.8 mm Hg among Whites to 141.3 mm Hg among Blacks (p = 0.06). For diabetes (n = 1211), adjusted A1c ranged from 7.7% among English-preferring Latinx to 8.7% among Blacks (p = 0.38). Care processes for both hypertension and diabetes varied across groups. No group consistently received lower-quality care. This UIHO provided care of comparable quality for hypertension and diabetes among urban-dwelling AI/ANs and members of other racial, ethnic, and language preference groups. Systematic assessments of care quality in UIHOs may help demonstrate the importance of their role in providing care and improve the quality of care.

Social Determinants of Health and Body Mass Index in American Indian/Alaska Native Children.

Objective: To examine the associations between social determinants of health (SDOH) and prevalent overweight/obesity status and change in adiposity status among American Indian and Alaska Native (AI/AN) children. Methods: The study sample includes 23,950 AI/AN children 2-11 years of age, who used Indian Health Service (IHS) from 2010 to 2014. Multivariate generalized linear mixed models were used to examine the following: (1) cross-sectional associations between SDOH and prevalent overweight/obesity status and (2) longitudinal associations between SDOH and change in adiposity status over time. Results: Approximately 49% of children had prevalent overweight/obesity status; 18% had overweight status and 31% had obesity status. Prevalent severe obesity status was 20% in 6-11-year olds. In adjusted cross-sectional models, children living in counties with higher levels of poverty had 28% higher odds of prevalent overweight/obesity status. In adjusted longitudinal models, children 2-5 years old living in counties with more children eligible for free or reduced-priced lunch had 15% lower odds for transitioning from normal-weight status to overweight/obesity status. Conclusions: This work contributes to accumulating knowledge that economic instability, especially poverty, appears to play a large role in overweight/obesity status in AI/AN children. Research, clinical practice, and policy decisions should aim to address and eliminate economic instability in childhood.

Social risks and social needs in a health insurance exchange sample: a longitudinal evaluation of utilization.

BACKGROUND: Health systems are increasingly attempting to intervene on social adversity as a strategy to improve health care outcomes. To inform health system efforts to screen for social adversity, we sought to explore the stability of social risk and interest in assistance over time and to evaluate whether the social risk was associated with subsequent healthcare utilization. METHODS: We surveyed Kaiser Permanente members receiving subsidies from the healthcare exchange in Southern California to assess their social risk and desire for assistance using the Accountable Health Communities instrument. A subset of initial respondents was randomized to be re-surveyed at either three or six months later. RESULTS: A total of 228 participants completed the survey at both time points. Social risks were moderate to strongly stable across three and six months (Kappa range = .59-.89); however, social adversity profiles that included participants' desire for assistance were more labile (3-month Kappa = .52; 95% CI = .41-.64 & 6-month Kappa = .48; 95% CI = .36-.6). Only housing-related social risks were associated with an increase in acute care (emergency, urgent care) six months after initial screening; no other associations between social risk and utilization were observed. CONCLUSIONS: This study suggests that screening for social risk may be appropriate at intervals of six months, or perhaps longer, but that assessing desire for assistance may need to occur more frequently. Housing risks were associated with increases in acute care. Health systems may need to engage in screening and referral to resources to improve overall care and ultimately patient total health.

Associations Between Rurality, pre-pregnancy Health Status, and Macrosomia in American Indian/Alaska Native Populations.

OBJECTIVES: To examine the relationships between pre-pregnancy diabetes mellitus (DM), gestational diabetes mellitus (GDM), pre-pregnancy body mass index (BMI) and county-level social determinants of health, with infant macrosomia within a sample of American Indian/Alaska Native (AI/AN) women receiving Indian Health Service (IHS) care. METHODS: The sample included women-infant dyads representing 1,136 singleton births from fiscal year 2011 (10/1/2019-9/30/2011). Data stemmed from the IHS Improving Health Care Delivery Data Project. Multivariate generalized linear mixed models were fitted to assess the association of macrosomia with pre-pregnancy health status and social determinants of health. RESULTS: Nearly half of the women in the sample were under age 25 years (48.6%), and most had Medicaid health insurance coverage (76.7%). Of those with a pre-pregnancy BMI measure, 66.2% were overweight or obese. Although few women had pre-pregnancy DM (4.0%), GDM was present in 12.8% of women. Most women had a normal term delivery (85.4%). Overweight, obesity, pre-pregnancy DM, and county-level rurality were all significantly associated with higher odds of infant macrosomia.

Association between changes in loneliness identified through screening and changes in depression or anxiety in older adults.

BACKGROUND: Changes in loneliness are associated with corresponding changes in depression, anxiety, and general health in population surveys, but few studies have assessed these associations through repeated screening in clinical settings. METHODS: Retrospective cohort study among individuals ≥age 65 in an integrated health care system who completed loneliness screening before two annual wellness visits, separated by a mean of 12.9 (SD 2.0) months, between 2013 and 2018. Their responses identified four subgroups: individuals who were persistently lonely; not lonely; experienced an increase (recently lonely); or decrease (previously lonely) in loneliness. Loneliness was assessed with a single item. Depression was assessed with the Patient Health Questionnaire-2. Anxiety was assessed with the Generalized Anxiety Disorder-2. Fair/poor general health was assessed by a single item. Linear mixed effects models assessed changes in outcomes after covariate adjustment. RESULTS: The cohort comprised 24,666 individuals (19.2% of older adults in the system). Mean age was 73.7 years (SD 6.4); 54.6% were female, and 11.6% were members of racial and ethnic minority groups. Of these individuals, 1936 (7.8%) were persistently lonely, 1687 (6.8%) were recently lonely, 1551 (6.3%) were previously lonely, and 19,492 (79.0%) were not lonely at either time point. After adjustment for sociodemographic, clinical and social variables, recent loneliness was associated with increases in depression (adjusted odds ratio [aOR] 1.76, 95% confidence interval [CI] 1.41-2.19) and anxiety (aOR 1.67, 95% CI 1.32-2.10). Previous loneliness was associated with decreases in depression (aOR, 0.46, 95% CI 0.36-0.58) and anxiety (aOR 0.69, 95% CI 0.54-0.90). Changes in loneliness were not associated with changes in general health. CONCLUSIONS: Changes in loneliness identified through screening were associated with corresponding changes in depression and anxiety. These findings support the potential value of identifying social risk factors in clinical settings among older adults.

Perspectives of Latinx Individuals Who Were Unvaccinated And Hospitalized for COVID-19: A Qualitative Study.

Importance: Latinx individuals in the United States have lower COVID-19 vaccination rates and higher rates of COVID-19 infections, hospitalizations, and deaths than non-Latinx White individuals. Little is known about the perspectives of Latinx adults who had not received the COVID-19 vaccination and were hospitalized for COVID-19. Objective: To describe the perspectives of Latinx individuals who were unvaccinated and subsequently hospitalized for COVID-19. Design, Setting, and Participants: This qualitative study was conducted using semistructured phone interviews with 25 Latinx adults who were unvaccinated and survived a COVID-19 hospitalization in a public safety net hospital in Colorado from February to November 2021. Interviews were audio recorded, and transcripts were analyzed using thematic analysis. Main Outcomes and Measures: Themes and subthemes of perspectives on vaccination. Results: Among 25 adults (14 [56.0%] women, 11 [44.0%] men; mean [SD] age, 51 [15] years) who participated, all participants self-identified as Latino, Latina, or Latinx or Hispanic. There were 11 individuals who relied on emergency Medicaid (hospital coverage for Denver residents who are undocumented), while 10 individuals (40.0%) were essential workers and 13 individuals (52.0%) were unemployed. In interviews, 3 themes (with subthemes) were identified: factors associated with vaccination after hospitalization (subthemes: fear of death, avoiding hospitalization and reinfection, convinced COVID-19 is real, and responded to pressure from others), concerns about the COVID-19 vaccine (subthemes: experimental status and short timeline for production, contents of vaccine unknown or concerning, vaccine considered ineffective, worrisome immediate and long-term adverse effects, mixed and conflicting information, and government aimed to control or mark population through vaccination), and opportunities to improve vaccine uptake (subthemes; sharing personal experiences through social media, testimonials about minimal vaccine adverse effects, connecting with friends and family about the hospitalization experience, making the vaccine more accessible, and connecting with trusted sources of information). Conclusions and Relevance: This study found that Latinx individuals who were unvaccinated and subsequently hospitalized for COVID-19 were motivated to engage in advocacy to encourage vaccination in their communities. These findings suggest that supporting patient advocacy after hospital discharge and continued efforts to create low-barrier, patient-informed public health strategies may be associated with increased vaccine uptake in Latinx communities.

Social determinants of obesity in American Indian and Alaska Native peoples aged ≥ 50 years.

OBJECTIVE: American Indian and Alaska Native peoples (AI/ANs) have a disproportionately high rate of obesity, but little is known about the social determinants of obesity among older AI/ANs. Thus, our study assessed social determinants of obesity in AI/ANs aged ≥ 50 years. DESIGN: We conducted a cross-sectional analysis using multivariate generalized linear mixed models to identify social determinants associated with the risk of being classified as obese (BMI ≥ 30.0 kg/m2). Analyses were conducted for the total study population and stratified by median county poverty level. SETTING: Indian Health Service (IHS) data for AI/ANs who used IHS services in FY2013. PARTICIPANTS: 27,696 AI/ANs aged ≥ 50 years without diabetes. RESULTS: Mean BMI was 29.8 ± 6.6 with 43% classified as obese. Women were more likely to be obese than men, and younger ages were associated with higher obesity risk. While having Medicaid coverage was associated with lower odds of obesity, private health insurance was associated with higher odds. Living in areas with lower rates of educational attainment and longer drive times to primary care services were associated with higher odds of obesity. Those who lived in a county where a larger percentage of people had low access to a grocery store were significantly less likely to be obese. CONCLUSIONS: Our findings contribute to the understanding of social determinants of obesity among older AI/ANs and highlight the need to investigate AI/AN obesity, including longitudinal studies with a life course perspective to further examine social determinants of obesity in older AI/ANs.

Relationship Between Social Vulnerability Indicators and Trial Participant Attrition: Findings From the HYVALUE Trial.

BACKGROUND: Social vulnerability indicators are associated with health care inequities and may similarly impede ongoing participation in research studies. We evaluated the association of social vulnerability indicators and research participant attrition in a trial focused on reducing health disparities. METHODS: Self-identified White or Black adults enrolled in the HYVALUE trial (Hypertension and VALUEs), a randomized trial testing a values-affirmation intervention on medication adherence, from February 2017 to September 2019 were included. The self-reported measures of social vulnerability indicators included: (1) Black race; (2) female gender; (3) no health insurance; (4) unemployment; (5) a high school diploma or less; and (6) financial-resource strain. Full attrition was defined as not completing at least one 3- or 6-month follow-up study visit. Log-binomial regression models adjusted for age, gender, race, medical comorbidities, and the other social vulnerability indicators to estimate the relative risk of each social vulnerability indicator with study attrition. RESULTS: Among 825 participants, the mean age was 63.3 years (±11.7 years), 60% were women, 54% were Black, and 97% reported at least one social vulnerability. Overall, 21% participants had full attrition after study enrollment. After adjustment for all other social vulnerabilities, only financial-resource strain remained consistently associated with full attrition (relative risk, 1.71 [95% CI, 1.28-2.29]). In a secondary analysis of partial attrition (completed only one follow-up visit), financial-resource strain (relative risk, 1.40 [95% CI, 1.09-1.81]) and being uninsured (relative risk, 1.54 [95% CI, 1.01-2.34]) were associated with partial attrition. CONCLUSIONS: In a trial aimed at reducing disparities in medication adherence, participants who reported financial-resource strain had a higher risk of participant attrition independent of race or gender. Our findings suggest that efforts to retain diverse populations in clinical trials should extend beyond race and gender to consider other social vulnerability indicators.
