Disparate Dementia Risk Factors Are Associated with Cognitive Impairment and Rates of Decline in African Americans

OBJECTIVE

This study was undertaken to evaluate the frequency of modifiable dementia risk factors and their association with cognitive impairment and rate of decline in diverse participants engaged in studies of memory and aging.

METHODS

Modifiable dementia risk factors and their associations with cognitive impairment and cognitive decline were determined in community-dwelling African American (AA; n = 261) and non-Hispanic White (nHW; n = 193) participants who completed ≥2 visits at the Mayo Clinic Alzheimer Disease Research Center in Jacksonville, Florida. Risk factors and their associations with cognitive impairment (global Clinical Dementia Rating [CDR] ≥ 0.5) and rates of decline (CDR Sum of Boxes) in impaired participants were compared in AA and nHW participants, controlling for demographics, APOE ɛ4 status, and Area Deprivation Index.

RESULTS

Hypertension, hypercholesterolemia, obesity, and diabetes were overrepresented in AA participants, but were not associated with cognitive impairment. Depression was associated with increased odds of cognitive impairment in AA (odds ratio [OR] = 4.30, 95% confidence interval [CI] = 2.13-8.67) and nHW participants (OR = 2.79, 95% CI = 1.21-6.44) but uniquely associated with faster decline in AA participants (β = 1.71, 95% CI = 0.69-2.73, p = 0.001). Fewer AA participants reported antidepressant use (9/49, 18%) than nHW counterparts (57/78, 73%, p < 0.001). Vitamin B12 deficiency was also associated with an increased rate of cognitive decline in AA participants (β = 2.65, 95% CI = 0.38-4.91, p = 0.023).

INTERPRETATION

Modifiable dementia risk factors are common in AA and nHW participants, representing important risk mitigation targets. Depression was associated with dementia in AA and nHW participants, and with accelerated declines in cognitive function in AA participants. Optimizing depression screening and treatment may improve cognitive trajectories and outcomes in AA participants. ANN NEUROL 2024;95:518-529.

Factors Associated With COVID-19 Vaccine Acceptance Among Patients Receiving Care at a Federally Qualified Health Center

BACKGROUND

COVID-19 vaccine hesitancy in the United States is high, with at least 63 million unvaccinated individuals to date. Socioeconomically disadvantaged populations experience lower COVID-19 vaccination rates despite facing a disproportionate COVID-19 burden.

OBJECTIVE

To assess the factors associated with COVID-19 vaccine acceptance among under-resourced, adult patients.

METHODS

Participants were patients receiving care at a Federally Qualified Health Center (FQHC) in St. Paul, Minnesota. Data were collected via multiple modes over 2 phases in 2020 (self-administered electronic survey) and 2021 (study team-administered survey by telephone, self-administered written survey) to promote diversity and inclusion for study participation. The primary outcome was COVID-19 vaccine acceptance. Using logistic regression analysis, associations between vaccine acceptance and factors including risk perception, concerns about the COVID-19 vaccine, social determinants of health (SDOH), co-morbidities, pandemic-induced hardships, and stress were assessed by adjusted odds ratios (AORs) and 95% confidence intervals (CI).

RESULTS

One hundred sixty-eight patients (62.5% female; mean age [SD]: 49.9 [17.4] years; 32% <$20 000 annual household income; 69%

CONCLUSIONS

Our study in a socioeconomically disadvantaged population suggests that risk perception is associated with an increased likelihood of vaccine acceptance, while concerns about the COVID-19 vaccine are associated with a lower likelihood of vaccine acceptance. As these factors could impact vaccine uptake, consistent, innovative, and context-specific risk communication strategies may improve vaccine coverage in this population.

Emergency Preparedness and Risk Communication Among African American Churches: Leveraging a Community-Based Participatory Research Partnership COVID-19 Initiative

The coronavirus disease 2019 (COVID-19) crisis has disproportionately affected the African American population. To mitigate the disparities, we deployed an emergency preparedness strategy within an existing community-based participatory research (CBPR) partnership among African American churches to disseminate accurate COVID-19 information. We used the Centers for Disease Control and Prevention Crisis and Emergency Risk Communication framework to conduct a needs assessment, distribute emergency preparedness manuals, and deliver COVID-19–related messaging among African American churches via electronic communication platforms. A needs assessment showed that the top 3 church emergency resource needs were financial support, food and utilities, and COVID-19 health information. During an 8-week period (April 3–May 31, 2020), we equipped 120 churches with emergency preparedness manuals and delivered 230 messages via social media (Facebook) and email. For reach, we estimated that 6,539 unique persons viewed content on the Facebook page, and for engagement, we found 1,260 interactions (eg, likes, loves, comments, shares, video views, post clicks). Emails from community communication leaders reached an estimated 12,000 church members. CBPR partnerships can be effectively leveraged to promote emergency preparedness and communicate risk among under-resourced communities during a pandemic.

The Partnership to Improve Diabetes Education Trial: a Cluster Randomized Trial Addressing Health Communication in Diabetes Care

BACKGROUND

Effective type 2 diabetes care remains a challenge for patients including those receiving primary care in safety net settings.

OBJECTIVE

The Partnership to Improve Diabetes Education (PRIDE) trial team and leaders from a regional department of health evaluated approaches to improve care for vulnerable patients.

DESIGN

Cluster randomized controlled trial.

PATIENTS

Adults with uncontrolled type 2 diabetes seeking care across 10 unblinded, randomly assigned safety net clinics in Middle TN.

INTERVENTIONS

A literacy-sensitive, provider-focused, health communication intervention (PRIDE; 5 clinics) vs. standard diabetes education (5 clinics).

MAIN MEASURES

Participant-level primary outcome was glycemic control [A1c] at 12 months. Secondary outcomes included select health behaviors and psychosocial aspects of care at 12 and 24 months. Adjusted mixed effects regression models were used to examine the comparative effectiveness of each approach to care.

KEY RESULTS

Of 410 patients enrolled, 364 (89%) were included in analyses. Median age was 51 years; Black and Hispanic patients represented 18% and 25%; 96% were uninsured, and 82% had low annual income level (< $20,000); adequate health literacy was seen in 83%, but numeracy deficits were common. At 12 months, significant within-group treatment effects occurred from baseline for both PRIDE and control sites: adjusted A1c (- 0.76 [95% CI, - 1.08 to - 0.44]; P < .001 vs - 0.54 [95% CI, - 0.86 to - 0.21]; P = .001), odds of poor eating (0.53 [95% CI, 0.33-0.83]; P = .01 vs 0.42 [95% CI, 0.26-0.68]; P < .001), treatment satisfaction (3.93 [95% CI, 2.48-6.21]; P < .001 vs 3.04 [95% CI, 1.93-4.77]; P < .001), and self-efficacy (2.97 [95% CI, 1.89-4.67]; P < .001 vs 1.81 [95% CI, 1.1-2.84]; P = .01). No significant difference was observed between study arms in adjusted analyses.

CONCLUSIONS

Both interventions improved the participant's A1c and behavioral outcomes. PRIDE was not more effective than standard education. Further research may elucidate the added value of a focused health communication program in this setting.

Factors associated with antidepressant use among low-income racially and ethnically diverse patients with type 2 diabetes

OBJECTIVE

Depression is common in patients with type 2 diabetes and associated with poor diabetes-related outcomes. We evaluated the factors associated with antidepressant use in a low-income, racially and ethnically diverse sample of patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

We performed a cross-sectional study of baseline data from participants in a cluster randomized trial evaluating a health literacy intervention for diabetes care in safety net clinics. Depressive symptoms were measured by the Center for Epidemiological Studies Depression Scale (CES-D); antidepressant use was abstracted from medication lists. Multivariable mixed effects logistic regression was used to evaluate the relationship between antidepressant use and race/ethnicity adjusting for depressive symptoms, age, gender, income, and health literacy.

RESULTS

Of 403 participants, 58% were non-Hispanic White, 18% were non-Hispanic Black, and 24% were Hispanic. Median age was 51 years old; 60% were female, 52% of participants had a positive screen for depression, and 18% were on antidepressants. Black and Hispanic participants were significantly less likely to be on an antidepressant compared with white participants, adjusted odds ratios 0.31(95% CI: 0.12 to 0.80) and 0.26 (95% CI: 0.10 to 0.74), respectively.

CONCLUSIONS

In this vulnerable population with type 2 diabetes, we found a high prevalence of depressive symptoms, and a small proportion of participants were on an antidepressant. Black and Hispanic participants were significantly less likely to be treated with an antidepressant. Our findings suggest depression may be inadequately treated in low-income, uninsured patients with type 2 diabetes, especially racial and ethnic minorities.

The Effects of Racism in Medical Education on Students' Decisions to Practice in Underserved or Minority Communities

PURPOSE

The purpose of this study was to examine the relationship between manifestations of racism in medical school and subsequent changes in graduating medical students' intentions to practice in underserved or minority communities, compared with their attitudes and intentions at matriculation.

METHOD

The authors used repeated-measures data from a longitudinal study of 3,756 students at 49 U.S. medical schools that were collected from 2010 to 2014. They conducted generalized linear mixed models to estimate whether manifestations of racism in school curricula/policies, school culture/climate, or student attitudes/behaviors predicted first- to fourth-year changes in students' intentions to practice in underserved communities or primarily with minority populations. Analyses were stratified by students' practice intentions (no/undecided/yes) at matriculation.

RESULTS

Students' more negative explicit racial attitudes were associated with decreased intention to practice with underserved or minority populations at graduation. Service learning experiences and a curriculum focused on improving minority health were associated with increased intention to practice in underserved communities. A curriculum focused on minority health/disparities, students' perceived skill at developing relationships with minority patients, the proportion of minority students at the school, and the perception of a tense interracial environment were all associated with increased intention to care for minority patients.

CONCLUSIONS

This study provides evidence that racism manifested at multiple levels in medical schools was associated with graduating students' decisions to provide care in high-need communities. Strategies to identify and eliminate structural racism and its manifestations in medical school are needed.

Factors influencing medical student self-competence to provide weight management services

This study aimed to identify factors associated with high obesity care self-competence among US medical students. The authors performed a cross-sectional analysis of 2014 survey data on fourth year medical students collected online as part of the Medical Student Cognitive Habits and Growth Evaluation Study (CHANGES). Independent variables included quality and quantity of interaction with patients and peers with obesity; hours of communication and partnership skills training; negative remarks against patients with obesity by supervising physicians, and witnessed discrimination against patients with obesity. The dependent variable was self-competence in providing obesity care. Of 5823 students invited to participate, 3689 (63%) responded and were included in our analyses. Most students were white (65%), half were women and 42% had high self-competence in caring for patients with obesity. Factors associated with high self-competence included increased interaction with peers with obesity (39% vs. 49%, P < 0.001) and increased partnership skills training (32% vs. 61%, P < 0.001). Increased partnership skills training and quantity of interactions with peers with obesity were associated with high student self-competence in providing obesity-related care to patients. Medical schools might consider increasing partnership skills training to improve students' preparedness and skill in performing obesity-related care.

Health Behaviors and Preventive Healthcare Utilization Among African-American Attendees at a Faith-Based Public Health Conference: Healthy Churches 2020

Unhealthy eating habits and physical inactivity along with lack of access to quality healthcare contribute to the marked health disparities in chronic diseases among African-Americans. Faith-based public health conferences offer a potential opportunity to improve health literacy and change health behaviors through health promotion within this population, thereby reducing health disparities. This study examined the self-reported health behaviors and preventive healthcare utilization patterns of 77 participants at a predominantly African-American faith-based public health conference, Healthy Churches 2020. A self-administered questionnaire was distributed to a sample of attendees to assess their health behaviors (diet and physical activity), preventive healthcare utilization (annual healthcare provider visits), and health-promoting activities at their places of worship. The results indicate that attendees of a faith-based public health conference have adequate preventive healthcare utilization, but suboptimal healthy behaviors. Our findings support the need for ongoing health-promoting activities with an emphasis on diet and physical activity among this population.

Association of Clinical Specialty With Symptoms of Burnout and Career Choice Regret Among US Resident Physicians

IMPORTANCE

Burnout among physicians is common and has been associated with medical errors and lapses in professionalism. It is unknown whether rates for symptoms of burnout among resident physicians vary by clinical specialty and if individual factors measured during medical school relate to the risk of burnout and career choice regret during residency.

OBJECTIVE

To explore factors associated with symptoms of burnout and career choice regret during residency.

DESIGN, SETTING, AND PARTICIPANTS

Prospective cohort study of 4732 US resident physicians. First-year medical students were enrolled between October 2010 and January 2011 and completed the baseline questionnaire. Participants were invited to respond to 2 questionnaires; one during year 4 of medical school (January-March 2014) and the other during the second year of residency (spring of 2016). The last follow-up was on July 31, 2016.

EXPOSURES

Clinical specialty, demographic characteristics, educational debt, US Medical Licensing Examination Step 1 score, and reported levels of anxiety, empathy, and social support during medical school.

MAIN OUTCOMES AND MEASURES

Prevalence during second year of residency of reported symptoms of burnout measured by 2 single-item measures (adapted from the Maslach Burnout Inventory) and an additional item that evaluated career choice regret (defined as whether, if able to revisit career choice, the resident would choose to become a physician again).

RESULTS

Among 4696 resident physicians, 3588 (76.4%) completed the questionnaire during the second year of residency (median age, 29 [interquartile range, 28.0-31.0] years in 2016; 1822 [50.9%] were women). Symptoms of burnout were reported by 1615 of 3574 resident physicians (45.2%; 95% CI, 43.6% to 46.8%). Career choice regret was reported by 502 of 3571 resident physicians (14.1%; 95% CI, 12.9% to 15.2%). In a multivariable analysis, training in urology, neurology, emergency medicine, and general surgery were associated with higher relative risks (RRs) of reported symptoms of burnout (range of RRs, 1.24 to 1.48) relative to training in internal medicine. Characteristics associated with higher risk of reported symptoms of burnout included female sex (RR, 1.17 [95% CI, 1.07 to 1.28]; risk difference [RD], 7.2% [95% CI, 3.1% to 11.3%]) and higher reported levels of anxiety during medical school (RR, 1.08 per 1-point increase [95% CI, 1.06 to 1.11]; RD, 1.8% per 1-point increase [95% CI, 1.6% to 2.0%]). A higher reported level of empathy during medical school was associated with a lower risk of reported symptoms of burnout during residency (RR, 0.99 per 1-point increase [95% CI, 0.99 to 0.99]; RD, -0.5% per 1-point increase [95% CI, -0.6% to -0.3%]). Reported symptoms of burnout (RR, 3.20 [95% CI, 2.58 to 3.82]; RD, 15.0% [95% CI, 12.8% to 17.3%]) and clinical specialty (range of RRs, 1.66 to 2.60) were both significantly associated with career choice regret.

CONCLUSIONS AND RELEVANCE

Among US resident physicians, symptoms of burnout and career choice regret were prevalent, but varied substantially by clinical specialty. Further research is needed to better understand these differences and to address these issues.

Medical School Factors Associated with Changes in Implicit and Explicit Bias Against Gay and Lesbian People among 3492 Graduating Medical Students

BACKGROUND

Implicit and explicit bias among providers can influence the quality of healthcare. Efforts to address sexual orientation bias in new physicians are hampered by a lack of knowledge of school factors that influence bias among students.

OBJECTIVE

To determine whether medical school curriculum, role modeling, diversity climate, and contact with sexual minorities predict bias among graduating students against gay and lesbian people.

DESIGN

Prospective cohort study.

PARTICIPANTS

A sample of 4732 first-year medical students was recruited from a stratified random sample of 49 US medical schools in the fall of 2010 (81% response; 55% of eligible), of which 94.5% (4473) identified as heterosexual. Seventy-eight percent of baseline respondents (3492) completed a follow-up survey in their final semester (spring 2014).

MAIN MEASURES

Medical school predictors included formal curriculum, role modeling, diversity climate, and contact with sexual minorities. Outcomes were year 4 implicit and explicit bias against gay men and lesbian women, adjusted for bias at year 1.

KEY RESULTS

In multivariate models, lower explicit bias against gay men and lesbian women was associated with more favorable contact with LGBT faculty, residents, students, and patients, and perceived skill and preparedness for providing care to LGBT patients. Greater explicit bias against lesbian women was associated with discrimination reported by sexual minority students (b = 1.43 [0.16, 2.71]; p = 0.03). Lower implicit sexual orientation bias was associated with more frequent contact with LGBT faculty, residents, students, and patients (b = -0.04 [-0.07, -0.01); p = 0.008). Greater implicit bias was associated with more faculty role modeling of discriminatory behavior (b = 0.34 [0.11, 0.57); p = 0.004).

CONCLUSIONS

Medical schools may reduce bias against sexual minority patients by reducing negative role modeling, improving the diversity climate, and improving student preparedness to care for this population.

Addressing Pediatric Obesity in Clinic

There is an epidemic of pediatric obesity in the United States. In most cases, there is an excess in the amount of calories consumed, compared with the amount of calories expended. Numerous body systems are affected by pediatric obesity, with complications varying between boys and girls. Behavioral, genetic, and environmental factors affect the ability of children to avoid becoming obese. Primary care physicians should screen for obesity in children as much as possible. Associated risk factors for obesity should be uncovered. Methods of preventing obesity should be discussed routinely with children and their families. Healthy dietary habits are key, and so are family-oriented interventions, such as eating together at dinnertime. One hour of moderate to vigorous activity daily is recommended for children and adolescents. While pediatric bariatric surgery is an option, there are also numerous nonpharmacological and pharmacological measures available as management for pediatric obesity. Family-based approaches, such as reducing screen time, have been very successful. Non-weight-bearing exercises also help children and adolescents expend calories without causing injury to themselves. Family availability, activity preference, and developmental levels should all be considerations when managing pediatric obesity. Motivational interviewing may also be helpful, especially when customized for each specific patient and family. Clinicians will play an increasing role in terms of identifying, treating, and preventing pediatric obesity; measures that can be done in the clinic should be considered more and more.

Validating Health Literacy and Numeracy Measures in Minority Groups

Background:

Validation studies of existing health literacy or numeracy tools among racial/ethnic minorities are limited.

Objective:

This study assessed the validity of the Subjective Numeracy Scale (SNS), the Diabetes Numeracy Test (DNT-5), the Brief Health Literacy Screen (BHLS), and the Short Test of Functional Health Literacy in Adults (S-TOFHLA) by trait (health literacy or numeracy) and by method (subjective or objective) among non-Hispanic white (NHW), non-Hispanic black (NHB), and Hispanic patients with type 2 diabetes mellitus (T2DM).

Methods:

We conducted a secondary analysis of baseline data from the Partnering to Improve Diabetes Education (PRIDE) study, a clustered randomized controlled trial testing the efficacy of a health communication intervention on T2DM outcomes at state Department of Health clinics in middle Tennessee. PRIDE participants with race/ethnicity data available (n = 398) were included in this study. Most patients identified as NHW (59%), 18% identified as NHB, and 23% identified as Hispanic. Pearson correlations among the 4 measures were compared for each racial/ethnic group by trait and method. The convergent validity of each measure with education was also assessed using Pearson correlation analyses.

Key Results:

Significant correlations were observed across all 3 subgroups for the numeracy measures (SNS and DNT-5) and the objective measures (DNT-5 and S-TOFHLA). Nonsignificant correlations were observed among Hispanic participants for the health literacy measures (BHLS and S-TOFHLA, correlation coefficient = 0.13) and among NHB and Hispanic participants for the subjective measures (SNS and BHLS, correlations coefficients = 0.15 and 0.09, respectively). A significant positive correlation was noted between education and each measure across all 3 subgroups.

Conclusions:

Subjective and health literacy measures demonstrate weaker correlations than objective and numeracy measures, respectively, among minority patients in this study. Our findings highlight the need to further evaluate the appropriateness of these tools for use with minority populations, particularly the BHLS for Hispanic patients. [Health Literacy Research and Practice. 2017;1(2):e23–e30.]

Plain Language Summary:

Few studies have tested the validity of health literacy and numeracy measures in minority groups. This study highlights racial/ethnic differences in the results of validity testing of the Subjective Numeracy Scale, the Diabetes Numeracy Test, the Brief Health Literacy Screen, and the Short Test of Functional Health Literacy in Adults among adults with type 2 diabetes.

Perceptions of Provider Communication Among Vulnerable Patients With Diabetes: Influences of Medical Mistrust and Health Literacy

Patient-provider communication is modifiable and is linked to diabetes outcomes. The association of communication quality with medical mistrust is unknown. We examined these factors within the context of a low-literacy/numeracy-focused intervention to improve diabetes care, using baseline data from diverse patients enrolled in a randomized trial of a health communication intervention. Demographics, measures of health communication (Communication Assessment Tool [CAT], Interpersonal Processes of Care survey [IPC-18]), health literacy (Short Test of Functional Health Literacy in Adults), depression, medical mistrust, and glycemic control were ascertained. Adjusted proportional odds models were used to test the association of mistrust with patient-reported communication quality. The interaction effect of health literacy on mistrust and communication quality was also assessed. A total of 410 patients were analyzed. High levels of mistrust were observed. In multivariable modeling, patients with higher mistrust had lower adjusted odds of reporting a higher CAT score (adjusted odds ratio [AOR] = 0.67, 95% confidence interval [CI] [0.52, 0.86], p = .003) and higher scores on the Communication (AOR = 0.69, 95% CI [0.55, 0.88], p = .008), Decided Together (AOR = 0.74, 95% CI [0.59, 0.93], p = .02), and Interpersonal Style (AOR = 0.69, 95% CI [0.53, 0.90], p = .015) subscales of the IPC-18. We observed evidence of an interaction effect of health literacy for the association between mistrust and the Decided Together subscale of the IPC-18 such that patients with higher mistrust and lower literacy perceived worse communication relative to mistrustful patients with higher literacy. In conclusion, medical mistrust was associated with poorer communication with providers in this public health setting. Patients' health literacy level may vary the effect of mistrust on interactional aspects of communication. Providers should consider the impact of mistrust on communication with vulnerable diabetes populations and focus efforts on mitigating its influence.

The PRIDE (Partnership to Improve Diabetes Education) Toolkit: Development and Evaluation of Novel Literacy and Culturally Sensitive Diabetes Education Materials

PURPOSE

Patients with low literacy, low numeracy, and/or linguistic needs can experience challenges understanding diabetes information and applying concepts to their self-management. The authors designed a toolkit of education materials that are sensitive to patients' literacy and numeracy levels, language preferences, and cultural norms and that encourage shared goal setting to improve diabetes self-management and health outcomes. The Partnership to Improve Diabetes Education (PRIDE) toolkit was developed to facilitate diabetes self-management education and support.

METHODS

The PRIDE toolkit includes a comprehensive set of 30 interactive education modules in English and Spanish to support diabetes self-management activities. The toolkit builds upon the authors' previously validated Diabetes Literacy and Numeracy Education Toolkit (DLNET) by adding a focus on shared goal setting, addressing the needs of Spanish-speaking patients, and including a broader range of diabetes management topics. Each PRIDE module was evaluated using the Suitability Assessment of Materials (SAM) instrument to determine the material's cultural appropriateness and its sensitivity to the needs of patients with low literacy and low numeracy. Reading grade level was also assessed using the Automated Readability Index (ARI), Coleman-Liau, Flesch-Kincaid, Fry, and SMOG formulas.

CONCLUSIONS

The average reading grade level of the materials was 5.3 (SD 1.0), with a mean SAM of 91.2 (SD 5.4). All of the 30 modules received a "superior" score (SAM >70%) when evaluated by 2 independent raters. The PRIDE toolkit modules can be used by all members of a multidisciplinary team to assist patients with low literacy and low numeracy in managing their diabetes.

Health communication, self-care, and treatment satisfaction among low-income diabetes patients in a public health setting

OBJECTIVE

Diabetes patients with limited resources often experience suboptimal care. Less is known about the role of effective health communication (HC) in caring for low income diabetes patients.

METHODS

Ten health department clinics in TN participated in a trial evaluating a literacy-sensitive communication intervention. We assessed the quality of baseline HC and measured associations with diabetes outcomes. Assessments included: demographics, measures of HC, health literacy, self-care behaviors, self-efficacy, medication non-adherence, treatment satisfaction, and A1C. Unadjusted and adjusted multivariable regression models were used to test associations.

RESULTS

Participants (N=411) were 49.7±9.5 years, 61% female, uninsured (96%), with A1C 9.6±2.1. In unadjusted analyses, better communication, was associated with lower medication non-adherence (OR 0.40-0.68, all p<0.05), higher treatment satisfaction (OR 1.76-1.96, all p<0.01), portion size reduction (OR 1.43, p<0.05), diabetes self-efficacy (OR 1.41, p<0.05), and lower A1C (β=-0.06, p<0.01). In adjusted analyses, communication quality remained associated with lower medication non-adherence (AOR 0.39-0.68, all p<0.05), and higher treatment satisfaction (AOR 1.90-2.21, all p<0.001).

CONCLUSIONS

Better communication between low-income patients and providers was independently associated with lower medication non-adherence and higher treatment satisfaction.

PRACTICE IMPLICATIONS

Communication quality may be an important modifiable approach to improving diabetes care for vulnerable populations.

Health literacy, physician trust, and diabetes-related self-care activities in Hispanics with limited resources

BACKGROUND

Hispanics with diabetes often have deficits in health literacy (HL). We examined the association among HL, psychosocial factors, and diabetes-related self-care activities.

METHODS

Cross-sectional analysis of 149 patients. Data included patient demographics and validated measures of HL, physician trust, self-efficacy, acculturation, self-care behaviors, and A1c.

RESULTS

Participants (N=60) with limited HL were older and less educated, and had more years with diabetes compared with adequate HL participants (N=89). Limited HL participants reported greater trust in their physician, greater self-efficacy, and better diet, foot care, and medication adherence. Health literacy status was not associated with acculturation or A1c. In adjusted analyses, HL status remained associated with physician trust, and we observed a notable but nonsignificant trend between HL status and medication adherence.

DISCUSSION

Lower HL was associated with greater physician trust and better medication adherence. Further research is warranted to clarify the role of HL and physician trust in optimizing self-care for Hispanics.

Psychosocial predictors of attitudes toward physician empathy in clinical encounters among 4732 1st year medical students: a report from the CHANGES study

OBJECTIVE

Medical school curricula intended to promote empathy varies widely. Even the most effective curricula leave a significant group of students untouched. Pre-existing student factors influence their response to learning experiences. We examined the individual predictors of first semester medical students' attitudes toward the value of physician empathy in clinical encounters.

METHODS

First year students (n=4732) attending a stratified random sample of 49 US medical schools completed an online questionnaire that included measures of dispositional characteristics, attitudes and beliefs, self-concept and well-being.

RESULTS

Discomfort with uncertainty, close-mindedness, dispositional empathy, elitism, medical authoritarianism, egalitarianism, self-concept and well-being all independently predicted first year medical students' attitudes toward the benefit of physician empathy in clinical encounters.

CONCLUSION

Students vary on their attitude toward the value of physician empathy when they start medical school. The individual factors that predict their attitudes toward empathy may also influence their response to curricula promoting empathic care.

PRACTICE IMPLICATIONS

Curricula in medical school promoting empathic care may be more universally effective if students' preexisting attitudes are taken into account. Messages about the importance of physician empathy may need to be framed in ways that are consistent with the beliefs and prior world-views of medical students.

The association of acculturation and health literacy, numeracy and health-related skills in Spanish-speaking caregivers of young children

Little is known about the relationship among acculturation, literacy, and health skills in Latino caregivers of young children. Latino caregivers of children < 30 months seeking primary care at four medical centers were administered measures of acculturation (SASH), functional health literacy (STOFHLA), numeracy (WRAT-3) and health-related skills (PHLAT Spanish). Child anthropomorphics and immunization status were ascertained by chart review. Caregivers (N = 184) with a median age of 27 years (IQR: 23-32) participated; 89.1% were mothers, and 97.1% had low acculturation. Lower SASH scores were significantly correlated (P < 0.01) with lower STOFHLA (ρ = 0.21), WRAT-3 (ρ = 0.25), and PHLAT Spanish scores (ρ = 0.34). SASH scores predicted PHLAT Spanish scores in a multivariable linear regression model that adjusted for the age of child, the age and gender of the caregiver, number of children in the family, the type of health insurance of the caregiver, and study site (adjusted β: 0.84, 95% CI 0.26-1.42, P = 0.005). This association was attenuated by the addition of literacy (adjusted β: 0.66, 95% CI 0.11-1.21, P = 0.02) or numeracy (adjusted β: 0.50, 95% CI -0.04-1.04, P = 0.07) into the model. There was no significant association between acculturation and up-to-date child immunizations or a weight status of overweight/obese. Lower acculturation was associated with worse health literacy and diminished ability to perform child health-related skills. Literacy and numeracy skills attenuated the association between acculturation and child health skills. These associations may help to explain some child health disparities in Latino communities.

A health literate approach to the prevention of childhood overweight and obesity

OBJECTIVE

To describe a systematic assessment of patient educational materials for the Growing Right Onto Wellness (GROW) trial, a childhood obesity prevention study targeting a low health literate population.

METHODS

Process included: (1) expert review of educational content, (2) assessment of the quality of materials including use of the Suitability Assessment of Materials (SAM) tool, and (3) material review and revision with target population.

RESULTS

12 core modules were developed and assessed in an iterative process. Average readability was at the 6th grade reading level (SMOG Index 5.63 ± 0.76, and Fry graph 6.0 ± 0.85). SAM evaluation resulted in adjustments to literacy demand, layout & typography, and learning stimulation & motivation. Cognitive interviews with target population revealed additional changes incorporated to enhance participant's perception of acceptability and feasibility for behavior change.

CONCLUSION

The GROW modules are a collection of evidence-based materials appropriate for parents with low health literacy and their preschool aged children, that target the prevention of childhood overweight/obesity.

PRACTICE IMPLICATIONS

Most trials addressing the treatment or prevention of childhood obesity use written materials. Due to the ubiquitous prevalence of limited health literacy, our described methods may assist researchers in ensuring their content is both understood and actionable.

Development and validation of a Spanish diabetes-specific numeracy measure: DNT-15 Latino

BACKGROUND

Although deficits in health literacy and numeracy have been described among Latinos, the impact of low numeracy on diabetes outcomes has not been studied. Study objectives were (1) to establish the reliability and validity of a 15-item Spanish, diabetes-specific numeracy measure (Diabetes Numeracy Test [DNT]-15 Latino) and (2) to examine the relationship between diabetes-specific numeracy and diabetes-related outcomes among a sample of Latino adults with diabetes.

METHODS

Data collection included patient demographics, health literacy, general numeracy, diabetes-specific numeracy, acculturation, self-efficacy, self-care behaviors, and most recent glycosylated hemoglobin (HbA1c).

RESULTS

Participants (n=144) were on average 47.8 years old (SD=12.1). The majority were female (62%), uninsured (81%), and of Mexican nationality (78%) and reported low levels of acculturation (96%). The DNT-15 Latino had high internal reliability (Kruder-Richardson 20=0.78). The DNT-15 Latino demonstrated construct validity, correlating with measures of health literacy (ρ=0.291), general numeracy (ρ=0.500), education (ρ=0.361), and income (ρ=0.270) (P<0.001 for each). The DNT-15 Latino was significantly associated with acculturation but unrelated to self-efficacy, self-care behaviors, insulin use, and HbA1c.

CONCLUSIONS

The DNT-15 Latino is a reliable and valid measure of diabetes-specific numeracy for Latino patients with diabetes; however, additional studies are needed to further explore the association between diabetes-specific numeracy and acculturation and their impact on diabetes-related outcomes for Latinos.

Health literacy explains racial disparities in diabetes medication adherence

Although low health literacy and suboptimal medication adherence are more prevalent in racial/ethnic minority groups than Whites, little is known about the relationship between these factors in adults with diabetes, and whether health literacy or numeracy might explain racial/ethnic disparities in diabetes medication adherence. Previous work in HIV suggests health literacy mediates racial differences in adherence to antiretroviral treatment, but no study to date has explored numeracy as a mediator of the relationship between race/ethnicity and medication adherence. This study tested whether health literacy and/or numeracy were related to diabetes medication adherence, and whether either factor explained racial differences in adherence. Using path analytic models, we explored the predicted pathways between racial status, health literacy, diabetes-related numeracy, general numeracy, and adherence to diabetes medications. After adjustment for covariates, African American race was associated with poor medication adherence (r = -0.10, p < .05). Health literacy was associated with adherence (r = .12, p < .02), but diabetes-related numeracy and general numeracy were not related to adherence. Furthermore, health literacy reduced the effect of race on adherence to nonsignificance, such that African American race was no longer directly associated with lower medication adherence (r = -0.09, p = .14). Diabetes medication adherence promotion interventions should address patient health literacy limitations.

Leveling the field: addressing health disparities through diabetes disease management

OBJECTIVES

To examine the relationships among patient characteristics, labor inputs, and improvement in glycosylated hemoglobin (A1C) level in a successful primary care-based diabetes disease management program (DDMP).

STUDY DESIGN

We performed subanalyses to examine the relationships among patient characteristics, labor inputs, and improvement in A1C level within a randomized controlled trial. Control patients received usual care, while intervention patients received usual care plus a comprehensive DDMP.

METHODS

The primary outcome was improvement in A1C level over 12 months stratified by intervention status and patient characteristics. Process outcomes included the number of actions or contacts with patients, time spent with patients, and number of glucose medication titrations or additions.

RESULTS

One hundred ninety-three of 217 enrolled patients (88.9%) had complete 12-month followup data. Patients in the intervention group had significantly greater improvement in A1C level than the control group (-2.1% vs -1.2%, P = .007). In multivariate analysis, no significant differences were observed in improvement in A1C level when stratified by age, race/ethnicity, income, or insurance status, and no interaction effect was observed between any covariate and intervention status. Among intervention patients, we observed similar labor inputs regardless of age, race/ethnicity, sex, education, or whether goal A1C level was achieved.

CONCLUSIONS

Among intervention patients in a successful DDMP, improvement in A1C level was achieved regardless of age, race/ethnicity, sex, income, education, or insurance status. Labor inputs were similar regardless of age, race/ethnicity, sex, or education and may reflect the nondiscriminatory nature of providing algorithm-based disease management care.

Diabetes numeracy: an overlooked factor in understanding racial disparities in glycemic control

OBJECTIVE

Understanding the reasons and eliminating the pervasive health disparities in diabetes is a major research, clinical, and health policy goal. We examined whether health literacy, general numeracy, and diabetes-related numeracy explain the association between African American race and poor glycemic control (A1C) in patients with diabetes.

RESEARCH DESIGN AND METHODS

Adults with type 2 diabetes (n = 383) were enrolled in a cross-sectional study at primary care and diabetes clinics at three medical centers. Data collected included the following: self-reported race, health literacy, general numeracy, diabetes-related numeracy, A1C, and sociodemographic factors. A series of structural equation models were estimated to explore the interrelations between variables and test for mediation.

RESULTS

In model 1, younger age (r = -0.21, P < 0.001), insulin use (r = 0.27, P < 0.001), greater years with diabetes (r = 0.16, P < 0.01), and African American race (r = 0.12, P < 0.01) were all associated with poorer glycemic control. In model 2, diabetes-related numeracy emerged as a strong predictor of A1C (r = -0.46, P < 0.001), reducing the association between African American and poor glycemic control to nonsignificance (r = 0.10, NS). In model 3, African American race and older age were associated with lower diabetes-related numeracy; younger age, insulin use, more years with diabetes, and lower diabetes-related numeracy were associated with poor glycemic control.

CONCLUSIONS

Diabetes-related numeracy reduced the explanatory power of African American race, such that low diabetes-related numeracy, not African American race, was significantly related to poor glycemic control. Interventions that address numeracy could help to reduce racial disparities in diabetes.

Health Care Disparities and Diabetes Care: Practical Considerations for Primary Care Providers

Disparities in diabetes care are prevalent in the United States. This article provides an overview of these disparities and discusses both potential causes and efforts to address them to date. The authors focus the discussion on aspects relevant to the patient-provider dyad and provide practical considerations for the primary care provider's role in helping to diminish and eliminate disparities in diabetes care.
