Progression of CKD in Hispanics: potential roles of health literacy, acculturation, and social support

The relationship between health literacy and problematic internet use in Chinese college students: The mediating effect of subject well-being and moderating effect of social support

BACKGROUND

The issue of problematic Internet use (PIU) amongst college students is emerging as a major concern for mental health. Factors such as health literacy, subjective well-being and the extent of social support may be critical in preventing PIU. However, the complex relationship between these factors has not been extensively explored in research.

METHODS

A national cross-sectional study based on multistage random sampling was conducted in China in 2022. The subjects for this study were 7669 college students who completed a set of questionnaires assessing their health literacy, subjective well-being, PIU and social support. A structural equation model (SEM) was utilised for exploring the mediating effect of subjective well-being, and the PROCESS macro was used to test the moderating effect of social support.

RESULTS

After controlling for demographic factors, a significantly negative correlation was found between health literacy and PIU, and subjective well-being partially mediated this relationship. In addition, social support was negatively related to PIU and could moderate the relationship between health literacy and subjective well-being and between subjective well-being and PIU.

LIMITATIONS

This is a cross-sectional study, and the results cannot inform the causality between these variables.

CONCLUSION

Results revealed that the relationship between health literacy and PIU was partially mediated by subjective well-being in college students. The correlation between health literacy and subjective well-being and between subjective well-being and PIU were moderated by social support. Thus, future interventions for college students' PIU should be facilitated by improving health literacy, subjective well-being and social support.

Prospective association of eHealth literacy and health literacy with physical activity among Chinese college students: a multiple mediation analysis

Background

The COVID-19 pandemic has decreased physical activity (PA) while increasing demand for electronic health resources. eHealth literacy (EHL) is expected to aid eHealth use and health promotion. EHL was raised on the grounds of health literacy (HL). This study explored the associations among EHL, HL, and PA in Chinese college students and identified mediating mechanisms in the EHL/HL-PA relationship.

Methods

An integrated social-cognitive model was proposed. A total of 947 Chinese college students (52.8% women, age = 19.87 ± 1.68 years) completed the three-wave data collection. Path analysis was performed.

Results

An adequate good-to-fit model was indicated. Perceived EHL (PEHL) was significantly associated with perceived HL (PHL) and HL performance (HLP); PHL was negatively related to HLP; PEHL was significantly associated with self-efficacy (SE) and social support (SS); PHL had a significant effect on SS but not SE; HLP significantly affected SS but not SE; SS and SE positively predicted intention (INT), which then predicted PA. SS mediated PEHL/PHL-INT links; SE mediated the PEHL-INT link; SS and INT jointly mediated PEHL/PHL/HLP-PA; SE and INT jointly mediated PEHL-PA.

Conclusion

Relationships among EHL, HL, and PA were explored with multiple mediating mechanisms identified. Differential SE and SS roles in EHL/HL-PA links suggest new mechanisms to inform EHL/HL intervention development.

Community-Engaged Research (CEnR) to Address Gaps in Chronic Kidney Disease Education among Underserved Latines-The CARE Study

Ensuring equitable chronic kidney disease (CKD) education for Latine patients with low health literacy and low English proficiency stands as a critical challenge, and the "Caridad Awareness and Education" (CARE) initiative represents our ongoing effort to address this imperative issue. In collaboration with twenty-three patients living with CKD, diabetes and/or hypertension and twelve trained Community Health Workers (CHWs) from diverse Latine subgroups, we conducted a research initiative funded by the National Kidney Foundation. Our primary objective was to co-design and test culturally tailored patient education materials (PEMs) for underserved Latine adults at risk for or diagnosed with CKD. We effectively integrated Community-Engaged Research (CEnR) principles with a Human-Centered Design (HCD) approach to create a range of CKD-PEM prototypes in Spanish. Patient preferences for printed educational materials were clear. They favored printed materials that incorporated visual content with concise text over digital, email, texts, or online resources and personalized phone outreach and the involvement of CHWs. Additionally, patients identified their unwavering commitment to their families as a forceful motivator for caring for their kidney health. Currently, a culturally and linguistically tailored CKD flipchart for one-on-one education, led by CHWs, is undergoing a pilot testing phase involving a sample of one hundred Latine patients at risk for or diagnosed with CKD. This innovative approach signifies a commitment to amplifying the insights and expertise of the Latine community afflicted by kidney health disparities, effectively embracing a CEnR to forge meaningful and impactful CKD-PEMs.

Association of Acculturation and Hispanic/Latino Background with Endogenous Sex and Thyroid-Related Hormones Among Middle-Aged and Older Hispanic/Latino Adults: the HCHS/SOL Study

BACKGROUND

Hormones are linked to cardiometabolic diseases and may be impacted by acculturation though multiple mechanisms. We evaluated associations of Hispanic/Latino background and acculturation with levels of sex- and thyroid-related hormones and the potential mediating effect of adiposity, lifestyle factors, and sleep apnea syndrome on these associations.

METHODS

We studied 1789 adults, aged 45-74, from a sub-cohort of the Hispanic Community Health Survey/Study of Latinos. Peri/pre-menopausal women and individuals on medications related to hormones were excluded. Our study assessed eleven sex- and thyroid-related hormones, Hispanic/Latino background, and five acculturation measures. Associations were assessed using multivariable linear and logistic regression adjusted for survey design and confounding variables. We explored potential mediation using a path analysis.

RESULTS

In postmenopausal women, acculturation score-MESA was associated with decreased thyroid-stimulating hormone (β = - 0.13;95%CI = - 0.22, - 0.03) while age at immigration greater than the median (vs US-born) was associated with decreased (β = - 14.6; 95%CI = - 28.2, - 0.99) triiodothyronine (T3). In men, language acculturation and acculturation score-MESA were associated with increased estradiol and sex hormone-binding globulin (SHBG) while age at immigration greater and lesser than the median (vs US-born) was associated with decreased SHBG. Hispanic/Latino background (Mexicans as reference) were selectively associated with sex- and thyroid-related hormone levels in both sexes. Current smoking and sleep apnea syndrome partially mediated the association of Cuban and Puerto Rican heritage (vs Mexican) with T3 levels in men and postmenopausal women, respectively.

CONCLUSION

Selected acculturation measures were associated with thyroid-related hormones in postmenopausal women and sex-related hormones in men. Understanding the mechanisms involved in the relationship of acculturation and Hispanic/Latino background with hormones warrants additional investigation.

The self-care behaviors and health literacy can play important preventive roles in older female osteoporosis

BACKGROUND

Osteoporosis is a common complication of aging and menopause. Self-care and health literacy are among the factors affecting health status. The purpose of this research was to determine the preventive roles of self-care behaviors and health literacy in older women with osteoporosis.

METHODS

This cross‑sectional analytical research was conducted on 250 postmenopausal women consisting of 125 osteoporotic and 125 healthy people aged 60-70. They were selected by purposive sampling in Tabriz Sina Hospital from September 2021 to December 2021. Data collection instruments were a demographic questionnaire, a Menopausal Self‑Care Questionnaire, and a European Health Literacy Survey Questionnaire. Data were analyzed using SPSS 23 software.

RESULTS

The mean (SD) total score of self-care in healthy women was 118.97 (19.92) and in women with osteoporosis was 84.7 (14.98) (p < 0.001). Also, healthy women all had sufficient health literacy (100%), but 52.8% of women with osteoporosis had insufficient health literacy. The odds of osteoporosis decreased significantly with the rise in the total score of self-care behaviors [Odds ratio 95% confidence interval (95% CI); p: 0.909 (0.880 to 0.939); p < 0.001] and its subdomains as well as with increasing health literacy level [OR (95% CI); p: 0.322 (0.266 to 0.383); p < 0.001]. There was a significant positive correlation between self-care behaviors and health literacy (r = 0.616, p < 0.001).

CONCLUSIONS

Self-care in aged women is particularly important in reducing the risk of osteoporosis, and empowering women in the field of health literacy is an important factor in improving self-care behaviors and ultimately the health of these people.

Delivery of an at-home transcranial direct current stimulation intervention to mitigate pain in patients with end-stage kidney disease receiving hemodialysis (ESKD/HD)

Background

Poorly controlled pain remains a problem for many patients with end-stage kidney disease requiring hemodialysis (ESKD/HD) and customary approaches to pain management (e.g., opioids, non-steroidals) confer substantial risk. Accordingly, non-pharmacologic therapies are needed for use in this population. Non-invasive transcranial Direct Current Simulation (tDCS) constitutes a promising nonpharmacologic method for pain management in affected individuals.

Aims

This study seeks to: 1) determine the effects of an 8-week course of at-home tDCS vs. sham tDCS on pain intensity, pain interference, medication usage, quality of life, and mood; 2) determine if tDCS effects vary by race/ethnicity; and 3) ascertain patient satisfaction with device use.

Methods

This double-blind, randomized, sham-controlled clinical trial will enroll 100 ESKD/HD patients with moderate-to-severe (≥4 on 0-10 scale) chronic pain. The active study intervention consists of 20 min of tDCS delivered over the primary motor cortex 5 days/week for 8 weeks. The comparator is a sham procedure that provides no effective stimulation. The primary outcome analysis will evaluate efficacy of tDCS for pain reduction after two months of stimulation. We will also assess the effects of treatment on analgesic consumption, pain interference, depressed mood, and quality of life. The statistical plan will include fixed classification factors for treatment (vs. sham), clinic sites, and assessment time, and the interaction of these factors adjusting for covariates (e.g., race/ethnicity, pain level).

Conclusion

At-home tDCS constitutes a promising nonpharmacologic treatment for pain mitigation in persons with ESKD/HD. This unique RCT could transform the way pain is managed in this vulnerable population.

Prospective associations of health literacy with clinical outcomes in adults with CKD: findings from the CRIC study

BACKGROUND

Limited health literacy is associated with significant morbidity and mortality in the general population but the relation of health literacy with long-term clinical outcomes among adults with chronic kidney disease (CKD) is less clear.

METHODS

Prospective data from the Chronic Renal Insufficiency Cohort (CRIC) Study (n = 3715) were used. Health literacy was assessed with the Short Test of Functional Health Literacy in Adults (dichotomized as limited/adequate). Cox proportional hazards models were used to separately examine the relations of health literacy with CKD progression, cardiovascular event (any of the following: myocardial infarction, congestive heart failure, stroke or peripheral artery disease), and all-cause, cardiovascular and non-cardiovascular mortality. Poisson regression was used to assess the health literacy-hospitalization association. Models were sequentially adjusted: Model 1 adjusted for potential confounders (sociodemographic factors), while Model 2 additionally adjusted for potential mediators (clinical and lifestyle factors) of the associations of interest.

RESULTS

In confounder-adjusted models, participants with limited (vs adequate) health literacy [555 (15%)] had an increased risk of CKD progression [hazard ratio (HR) 1.34; 95% confidence interval (CI) 1.06-1.71], cardiovascular event (HR 1.67; 95% CI 1.39-2.00), hospitalization (rate ratio 1.33; 95% CI 1.26-1.40), and all-cause (HR 1.54; 95% CI 1.27-1.86), cardiovascular (HR 2.39; 95% CI 1.69-3.38) and non-cardiovascular (HR 1.27; 95% CI 1.01-1.60) mortality. Additional adjustments for potential mediators (Model 2) showed similar results except that the relations of health literacy with CKD progression and non-cardiovascular mortality were no longer statistically significant.

CONCLUSIONS

In the CRIC Study, adults with limited (vs adequate) health literacy had a higher risk for CKD progression, cardiovascular event, hospitalization and mortality-regardless of adjustment for potential confounders.

Helping Relationships From Significant Others Scale: Chinese Version

Using the helping relationships from significant others (HRSO) scale assists patients, such as those with chronic kidney disease (CKD), in adopting a healthy lifestyle to decelerate disease progression, complications, and mortality. To study the efficacy of the scale, we recruited a convenience sample (n = 250) of patients with CKD from a nephrology clinic in southern Taiwan. Principal axis factor analysis and a promax rotation revealed a 15-item, three-factor explanation of 68.44 % of the total variance. The confirmatory factor analysis showed a good fit. The Composite reliability was .91, .89, and .92 in the same factors. Cronbach's alpha was .90 for the 15-item scale, with the 3 subscales ranging from .86 to .91. The split reliability was .73. The HRSO is a valid and reliable scale to measure significant others' support of patients with CKD in maintaining a healthy lifestyle.

Association Between Social Support and Medication Literacy in Chinese Patients With Coronary Heart Disease

Background: The level of medication literacy is very important to control symptoms and improve the prognosis of patients with coronary heart disease (CHD). The positive role of social support is able to promote patient health outcomes. However, few studies have addressed the association between social support and medication literacy in patients with CHD. The purpose of this study is to investigate the status of medication literacy and social support, and confirm the association between them in patients with CHD.

Methods: This cross-sectional study investigated 416 participants, and was conducted in a grade a hospital in China. Three different survey instruments were applied: The Demographic Characteristics Questionnaire, the Chinese Version of the Medication Literacy Scale, and the Social Support Rating Scale. Pearson correlation analysis and ordinal logistic regression analysis were performed to analyze data.

Results: The results showed that the mean score of medication literacy among the 416 participants was 4.96 ± 4.68, 48.8% (203) participants with inadequate medication literacy. The independent determinants of medication literacy include gender, education level, course of disease, number of medicines, and subjective support in social support. The mean score of social support was 41.05 ± 6.16. The Pearson correlation analysis indicated that social support was positively correlated with medication literacy (r = 0.398, P < 0.01).

Conclusion: The study shows that the level of medication literacy and social support for patients with CHD are inadequate. Social support levels could have a positive effect on medication literacy of patients.

Effects of helping relationships on health-promoting lifestyles among patients with chronic kidney disease: A randomized controlled trial

BACKGROUND

Healthy behaviors can slow the progression of chronic kidney disease. Professional healthcare providers deliver education, physical exercise programs, motivation consultations, and stage-tailored strategies for improving health behaviors, but their effectiveness reported mixed. The helping relationships of significant others based on the transtheoretical model have been shown to be beneficial in facilitating and practicing health-promoting behaviors. However, few studies have examined the effects of helping relationships on health-promoting behaviors among patients with chronic kidney disease.

OBJECTIVES

The aim of this study was to examine the effects of the intervention strategies of significant others in their helping relationships with patients to advance stages of exercise and diet behaviors, and to improve health-promoting lifestyles.

DESIGN

A randomized controlled study.

SETTINGS

Two outpatient nephrology clinics in southern Taiwan.

PARTICIPANTS

Sixty participants in each of the two groups.

METHODS

Patients were randomly assigned to either the intervention group (n = 60) whose significant others received strategies for helping relationships for 12 months, or the control group (n = 60). The Stage of Change of Exercise and Diet Behaviors, and Health Promoting Lifestyle Profile-II Chinese version were assessed at baseline and 3, 6, 9, and 12 months after receiving the helping relationship interventions tailored to stage of change from significant others.

RESULTS

Generalized estimating equation analyzes revealed that the intervention group, when compared to the control group, had significantly advanced stages of change in exercise and diet, and improvement in health-promoting lifestyle over time. Adult children and spouses were the most common significant others to help patients practice healthy behaviors, compared to previous studies where professional healthcare providers were the significant others.

CONCLUSIONS

Individualized plans for healthy behaviors should take into consideration patients' readiness for adopting stage-tailored strategies of helping relationships of significant others to adhere to the health-promoting lifestyle. To promote a healthier lifestyle, significant others, such as spouses and adult children, should be included in treatment programs.

Emerging Patient-Centered Concepts in Pain Among Adults With Chronic Kidney Disease, Maintenance Dialysis, and Kidney Transplant

Patient reports of moderate to severe pain are common across the spectrum of chronic kidney disease. The synergistic effects of comorbid depression and anxiety can lead to maladaptive coping responses to pain, namely pain catastrophizing and illness-related post-traumatic stress disorder. If underlying depression and anxiety and associated maladaptive coping responses are not treated, patients can experience an increased perception of pain, worsened disability, decreased quality of life, withdrawal from social activities, and increased morbidity and mortality. Meanwhile, interest in nonpharmacologic treatments for pain that targets coping as well as comorbid anxiety and depression has been increasing, particularly given the significant societal damage that has resulted from the opioid epidemic. Evidence-based, nonpharmacologic treatments have shown promise in treating pain in areas outside of nephrology. Currently, little is known about the effects of these treatments among adults with CKD, and particularly end-stage kidney disease, when chronic pain can become debilitating. In this review, we examine patient-centered concepts related to pain that have received little attention in the nephrology literature. We also describe emerging areas of research, including omics technologies for biomarker discovery and advanced symptom clustering methods for symptom phenotyping, which may be useful to future kidney disease research and treatment.

Development and application of a chronic kidney disease-specific health literacy, knowledge and disease awareness assessment tool for patients with chronic kidney disease in Taiwan

OBJECTIVES

This study aims to develop an assessment tool for health literacy and knowledge specific to chronic kidney disease (CKD) for use in examining the associations between health literacy, disease-specific knowledge and disease awareness among patients with CKD in Taiwan.

DESIGN

An assessment tool in Mandarin and Taiwanese was developed based on patient input, panel discussions with experts and a literature review, and checked for validity and reliability in a pilot test. Formal data were collected through population-based sampling with a set quota according to region and hospital accreditation level. Cross-sectional data were collected to confirm the reliability and validity of the assessment tool. Levels of health literacy, disease knowledge, and disease awareness were then reported and analysed.

SETTING

Sample hospitals included 10 medical centres, 18 regional hospitals and 15 local hospitals in Taiwan. Researchers were granted Internal Review Board approval and obtained agreement to collect data in all study settings.

PARTICIPANTS

Patients at least 20 years old who had been diagnosed with CKD of any stage were eligible to participate. The formal assessment collected 1155 valid questionnaires, yielding an 87.3% response rate. The mean age of participants was 67.48 years (SD=12.87, range 22-98), while 484 (41.95%) were female and 78% were aware they had CKD.

RESULTS

The self-devised instrument proved to have excellent reliability and validity. Use of the instrument in the main study showed that CKD-specific health literacy was significantly associated with age (β=-0.33, p<0.00), educational attainment and disease awareness (β=0.13, p<0.00). CKD-specific knowledge was also significantly associated with age (β=-0.18, p<0.00), educational attainment and disease awareness (β=0.19, p<0.00).

CONCLUSIONS

This CKD-specific health literacy and knowledge assessment tool developed for Mandarin and Taiwanese-speaking patients is reliable and well validated. Patients with CKD who are aware of and understand their disease performed better in the assessment.

Effect of Marital Status on Depression and Mortality among Patients with Chronic Kidney Disease from National Health and Nutrition Examination Survey 2005-2014

BACKGROUND

The relationship between marital status and CKD is rarely studied. We aimed to explore the effect of marital status on the depression and mortality of patients with CKD.

METHODS

The data sources came from the NHANES database during 2005-2014 and 3,865 participants were included in this study. We used logistic regression models to examine the relationship between marital status and depression of CKD patients. The Cox proportional hazard models were used to evaluate the association between marital status and mortality of CKD patients.

RESULTS

In terms of depression in CKD patients, unmarried patients had a worse situation than married patients. Meanwhile, after adjusting the covariables, unmarried patients had increased risk of depression (OR = 1.26, 95% CI: 1.01-1.57) compared with married CKD patients, especially in males (OR = 1.45, 95% CI: 1.02-2.06) and patients with more than college education level (OR = 12.4, 95% CI: 3.75-41.02). There was a significant relationship between marital status and mortality of general CKD patients (HR = 1.36, 95% CI: 1.17-1.58). Moreover, marriage showed a protective effect against death among male patients, patients with school graduate or less and more than college educational level, patients with high income, and patients in different estimated glomerular filtration rate groups.

CONCLUSIONS

The use of large numbers of participants has revealed the effect of marital status on CKD patients. Unmarried ones had a higher risk of depression than married ones among CKD patients. Meanwhile, the risk of death was higher in unmarried ones than married ones among CKD patients in this study.

The Influence of Health Literacy and Social Support on Loneliness Among Patients With Severe Mental Illness in Rural Southwest China

Loneliness is an important risk factor for poor health outcomes among adults, especially among those with severe mental illnesses (SMIs). Existing research has shown that adults with SMIs often lack health literacy, which contributes to more restricted social networks and low levels of social support. The objective of this cross-sectional study was to examine the influence of health literacy and social support on the loneliness of patients with SMI in rural Southwest China. We recruited 300 patients with SMI in rural Southwest China between December, 2017 to May, 2018 via a multi-stage stratified random sampling approach. We used structural equation modeling (SEM) test the hypothesized relationships among the variables of the 270 patients who completed the survey. Results of the SEM showed that health literacy was both directly and indirectly associated with loneliness, with social support playing a mediating role. These findings suggest psychoeducation for SMI patients, and their informal caregivers, may offer beneficial effects toward reducing loneliness in this vulnerable population. Further, social support is another potential target for intervention development for improving patient outcomes.

Poverty, Racism, and the Public Health Crisis in America

The purpose of this article is to discuss poverty as a multidimensional factor influencing health. We will also explicate how racism contributes to and perpetuates the economic and financial inequality that diminishes prospects for population health improvement among marginalized racial and ethnic groups. Poverty is one of the most significant challenges for our society in this millennium. Over 40% of the world lives in poverty. The U.S. has one of the highest rates of poverty in the developed world, despite its collective wealth, and the burden falls disproportionately on communities of color. A common narrative for the relatively high prevalence of poverty among marginalized minority communities is predicated on racist notions of racial inferiority and frequent denial of the structural forms of racism and classism that have contributed to public health crises in the United States and across the globe. Importantly, poverty is much more than just a low-income household. It reflects economic well-being, the ability to negotiate society relative to education of an individual, socioeconomic or health status, as well as social exclusion based on institutional policies, practices, and behaviors. Until structural racism and economic injustice can be resolved, the use of evidence-based prevention and early intervention initiatives to mitigate untoward effects of socioeconomic deprivation in communities of color such as the use of social media/culturally concordant health education, social support, such as social networks, primary intervention strategies, and more will be critical to address the persistent racial/ethnic disparities in chronic diseases.

Psychological and relational factors in ESRD hemodialysis treatment in an underserved community

OBJECTIVE

The researchers investigated the association of depression with treatment adherence, and examined the possible moderating roles of social support and of the physician-patient working alliance (PPWA) on treatment adherence, satisfaction with treatment, and quality of life.

METHODS

The current study sampled ninety-five patients with End Stage Renal Disease who were receiving outpatient hemodialysis (HD) treatment.

RESULTS

Findings indicated that higher levels of depression were significantly associated with lower ratings of adherence, quality of life, and social support. In contrast, higher levels of social support and of the PPWA were significantly associated with higher ratings of adherence, satisfaction with treatment, and quality of life. Analyses of moderation showed no effect for PPWA between depression and adherence, satisfaction, or quality of life; however, there was a significant moderation effect for social support.

CONCLUSION

There are mild but significant associations between PPWA and social support. Positive associations between the PPWA and social support on adherence, satisfaction, and quality of life indicate that each one, PPWA and social support, plays its own role on patients' experiences of and behavior in treatment. Affective social support significantly limits the negative influence of depression on adherence.

PRACTICE IMPLICATIONS

Assessment of depression and social support is essential in hemodialysis treatment.

Social Determinants of Health and Chronic Kidney Disease

In the United States, chronic kidney disease (CKD) remains a concern to the health of 37 million adults. Prevention is key to combatting this disease before it is able to progress into its advanced stages or end-stage renal disease (ESRD). Awareness of the clinical early detection of CKD is important for healthcare providers, but a look at the causes of this disease can provide for greater evaluation of the patient’s risks. Understanding of social determinants of health (SDOH), the non-clinical aspects of a patient’s life that affect disease onset and progression, and its effects on CKD and ESRD should be greater emphasized in the primary care field. Population groups living with relatively poorer SDOH are disproportionally affected by CKD and ESRD. Although political change is out of the scope of the primary care health provider, efforts in combatting poor social determinants can provide for better outcomes for at-risk or diagnosed patients. Education and screening are two suggestions brought up in literature for tackling SDOH, specifically in the primary care settings most applicable to CKD.

Incident Chronic Kidney Disease Risk among Hispanics/Latinos in the United States: The Hispanic Community Health Study/Study of Latinos (HCHS/SOL)

BACKGROUND

Although Hispanics/Latinos in the United States are often considered a single ethnic group, they represent a heterogenous mixture of ancestries who can self-identify as any race defined by the U.S. Census. They have higher ESKD incidence compared with non-Hispanics, but little is known about the CKD incidence in this population.

METHODS

We examined rates and risk factors of new-onset CKD using data from 8774 adults in the Hispanic Community Health Study/Study of Latinos. Incident CKD was defined as eGFR <60 ml/min per 1.73 m² with eGFR decline ≥1 ml/min per 1.73 m² per year, or urine albumin/creatinine ratio ≥30 mg/g. Rates and incidence rate ratios were estimated using Poisson regression with robust variance while accounting for the study's complex design.

RESULTS

Mean age was 40.3 years at baseline and 51.6% were women. In 5.9 years of follow-up, 648 participants developed CKD (10.6 per 1000 person-years). The age- and sex-adjusted incidence rates ranged from 6.6 (other Hispanic/mixed background) to 15.0 (Puerto Ricans) per 1000 person-years. Compared with Mexican background, Puerto Rican background was associated with 79% increased risk for incident CKD (incidence rate ratios, 1.79; 95% confidence interval, 1.33 to 2.40), which was accounted for by differences in sociodemographics, acculturation, and clinical characteristics. In multivariable regression analysis, predictors of incident CKD included BP >140/90 mm Hg, higher glycated hemoglobin, lower baseline eGFR, and higher baseline urine albumin/creatinine ratio.

CONCLUSIONS

CKD incidence varies by Hispanic/Latino heritage and this disparity may be in part attributed to differences in sociodemographic characteristics. Culturally tailored public heath interventions focusing on the prevention and control of risk factors might ameliorate the CKD burden in this population.

'If I knew what was going to happen, it wouldn't worry me so much': Children's, parents' and health professionals' perspectives on information for children undergoing a procedure

Children undergoing procedures such as blood tests and X-rays experience less anxiety and upset if they are well prepared and informed. Currently the provision of information about procedures can be ad hoc and there are barriers to children understanding this information. This study explored the perspectives of 32 children undergoing procedures (aged between 8 and 12 years), 27 parents and 19 health professionals on the provision of preparatory information to children. Qualitative interviews, prompted by visual images, were thematically analysed. The three themes, 'accessing information', 'understanding information' and 'using information', resonated with the central tenets of health literacy. Children reported mainly accessing information second-hand through their parents and demonstrated misconceptions about their procedure. Children identified that procedural information would help them to know what was going to happen and enable them to feel less worried and scared about their procedure. This study highlights that children can have low levels of health literacy in relation to a planned procedure. Their health literacy in this context is heavily influenced by the adults (parents and health professionals) around them. There needs to be further work conducted, informed directly by children, to improve the health literacy of children attending hospital for planned procedures.

Patient Navigation: Addressing Social Challenges in Dialysis Patients

Members of racial and ethnic minority groups make up nearly 50% of US patients with end-stage kidney disease and face a disproportionate burden of socioeconomic challenges (ie, low income, job insecurity, low educational attainment, housing instability, and communication challenges) compared with non-Hispanic whites. Patients with end-stage kidney disease who face social challenges often have poor patient-centered and clinical outcomes. These challenges may have a negative impact on quality-of-care performance measures for dialysis facilities caring for primarily minority and low-income patients. One path toward improving outcomes for this group is to develop culturally tailored interventions that provide individualized support, potentially improving patient-centered, clinical, and health system outcomes by addressing social challenges. One such approach is using community-based culturally and linguistically concordant patient navigators, who can serve as a bridge between the patient and the health care system. Evidence points to the effectiveness of patient navigators in the provision of cancer care and, to a lesser extent, caring for people with chronic kidney disease and those who have undergone kidney transplantation. However, little is known about the effectiveness of patient navigators in the care of patients with kidney failure receiving dialysis, who experience a number of remediable social challenges.

Evaluation of pharmacy-based telephone interventions on medication pick-up rates: a retrospective, quality improvement study at charity outpatient clinics

OBJECTIVES

To evaluate a live telephonic outreach intervention made by clinical pharmacists and clinical pharmacy technicians on medication pick-up rates.

METHODS

A retrospective, quality improvement study conducted at six outpatient charity clinics in Dallas-Fort Worth area between 1 January 2017 and 31 July 2017. A live telephonic call was made by a pharmacy team member if the patient did not pick-up at least one prescription item. Patients may receive more than one call if they did not pick-up medication(s) more than once during the study period. A live telephonic call resulted in three categories: contacted, left a voice message and unable to contact. Medication pick-up rates were obtained from a pharmacy claims database.

KEY FINDINGS

The study population included 1726 individual patients who failed to pick-up at least one medication from Baylor Scott & White Health pharmacy. A total of 2551 live telephonic calls were made for the study population. A total of 1175 live telephonic calls (46.1%, n = 2551) resulted in a patient picking up medication(s). Results from the generalized estimating equation logistic regression models showed that patients who received a voice message (OR: 1.37; 95% CI: 1.05 to 1.80; P < 0.021) or was contacted (OR: 1.99; 95% CI: 1.54 to 2.60; P < 0.001) were more likely to pick-up their medications as compared to the 'unable to contact' group.

CONCLUSIONS

Telephonic interventions from the pharmacy team can serve as a successful means to increase medication pick-up rates among charity clinic patients.

A multi-component, family-focused and literacy-sensitive intervention to improve medication adherence in patients with heart failure-A randomized controlled trial

BACKGROUND

Medication nonadherence is prevalent and links to serious outcomes (e.g., rehospitalization/death) in heart failure (HF) patients; therefore, an urgent need exists for an intervention to improve and sustain adherence after intervention completion.

OBJECTIVES

To test the efficacy of a multi-component, family-focused, literacy-sensitive (FamLit) intervention on medication adherence in HF patients.

METHODS

Forty-three HF patients and their care partners were enrolled and randomized to receive FamLit or attention-only intervention, including an in-person session at baseline and bi-weekly phone boosters for 3 months. We measured medication adherence from baseline to 3-month post-intervention using the Medication Event Monitoring System.

RESULTS

After 3-month intervention, intervention patients had significantly better medication adherence than control patients. At 6 months (3-months post-intervention), intervention effect on adherence was sustained in the FamLit intervention group, while adherence decreased in the control group.

CONCLUSION

Incorporating care partner support and providing an easy-to-understand intervention to patients-care partners may improve/sustain adherence.

Peer Navigator Intervention for Latinos on Hemodialysis: A Single-Arm Clinical Trial

Background: Latinos with end-stage renal disease (ESRD) have worse mental and kidney composite health-related quality of life (HRQOL) scores compared to non-Latino ESRD patients. Latino ESRD patients uniquely report that social factors (e.g., lack of care coordination, food insecurity, and low health literacy) and mental health influence their HRQOL. We developed a culturally tailored peer navigator (PN) intervention to improve the HRQOL of Latinos on hemodialysis. Objective: To determine the feasibility of the PN intervention. Design: Single-arm prospective study. The PN provided individualized support with advance care planning, care coordination, and counseling about the importance of diet and mental health. Setting and Participants: Latino with ESRD receiving scheduled outpatient thrice-weekly hemodialysis or reliant on emergency-only hemodialysis in Denver. Main measures: Recruitment, retention rates, data completeness, intervention dose, patient- and staff-reported satisfaction with the intervention. Results: Of 49 eligible patients, 40 (82%) agreed to participate. The majority of participants received scheduled outpatient hemodialysis (75%), 20 were women (50%), with a mean (standard deviation [SD]) age of 56 (13) years. No participants withdrew from the intervention. One participant died. The mean (SD) number of PN visits per participant was 7 (2) and the mean (SD) length of the visits was 97 minutes (49). The majority of visits took place at the hemodialysis facility (59%) and home (27%). The vast majority of participants reported that the PN improved their quality of life as a patient on hemodialysis (95%). Conclusions: The PN intervention achieved feasibility goals and was well received by participants.

"End-of-Life Care? I'm not Going to Worry About That Yet." Health Literacy Gaps and End-of-Life Planning Among Elderly Dialysis Patients

Purpose

Between 2000 and 2012, the incident dialysis population in the United States increased by nearly 60%, most sharply among adults 75 years and older. End-of-life (EOL) conversations among dialysis patients are associated with better patient-centered outcomes and lower use of aggressive interventions in the last month of life. This study examined how health literacy may affect engagement, comprehension, and satisfaction with EOL conversations among elderly dialysis patients.

Design and Methods

Qualitative/descriptive study with semi-structured interviews about health literacy, EOL conversations, and goals of care with 31 elderly dialysis patients at 2 centers in Boston. Themes were interpreted in the context of Nutbeam's health literacy framework.

Results

Despite high mortality risk in this population, only 13% of patients had discussed EOL preferences with physicians, half had discussed EOL with their social network, and 25% of participants explicitly stated that they had never considered EOL preferences. Less than 30% of participants could correctly define terminology commonly used in EOL conversations. Analyses yielded 5 themes: (1) Misunderstanding EOL terminology; (2) Nephrologists reluctant to discuss EOL; (3) Patients conforming to socially constructed roles; (4) Discordant expectations and dialysis experiences; and (5) Reconciling EOL values and future care. Patients had limited understanding of EOL terminology, lacked of opportunities for meaningful EOL discussion with providers and family, resulting in uncertainty about future care.

Implications

Limited health literacy presents a substantial barrier to communication and could lead to older adults committing to an intensive pattern of care without adequate information. Clinicians should consider health literacy when discussing dialysis initiation.

CKD and ESRD in US Hispanics

Hispanics are the largest racial/ethnic minority group in the United States, and they experience a substantial burden of kidney disease. Although the prevalence of chronic kidney disease (CKD) is similar or slightly lower in Hispanics than non-Hispanic whites, the age- and sex-adjusted prevalence rate of end-stage renal disease is almost 50% higher in Hispanics compared with non-Hispanic whites. This has been attributed in part to faster CKD progression among Hispanics. Furthermore, Hispanic ethnicity has been associated with a greater prevalence of cardiovascular disease risk factors, including obesity and diabetes, as well as CKD-related complications. Despite their less favorable socioeconomic status, which often leads to limited access to quality health care, and their high comorbid condition burden, the risk for mortality among Hispanics appears to be lower than for non-Hispanic whites. This survival paradox has been attributed to a complex interplay between sociocultural and psychosocial factors, as well as other factors. Future research should focus on evaluating the long-term impact of these factors on patient-centered and clinical outcomes. National policies are needed to improve access to and quality of health care among Hispanics with CKD.

Acculturation and chronic kidney disease in the Hispanic community health study/study of Latinos (HCHS/SOL)

Hispanics/Latinos are burdened by chronic kidney disease (CKD). The role of acculturation in this population has not been explored. We studied the association of acculturation with CKD and cardiovascular risk factor control. We performed cross-sectional analyses of 13,164 U.S. Hispanics/Latinos enrolled in the HCHS/SOL Study between 2008 and 2011. Acculturation was measured using the language and ethnic social relations subscales of the Short Acculturation Scale for Hispanics, and proxies of acculturation (language preference, place of birth and duration of residence in U.S.). CKD was defined as estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m² or urine albumin-to-creatinine ratio ≥ 30 mg/g. On multivariable analyses stratified by age, lower language subscale score was associated with higher odds of CKD among those older than 65 (OR 1.29, 95% CI, 1.03, 1.63). No significant association was found between proxies of acculturation and CKD in this age strata. Among individuals aged 18–44, a lower language subscale score was associated with lower eGFR (β = −0.77 ml/min/1.73 m², 95% CI −1.43, −0.10 per 1 SD increase) and a similar pattern was observed for ethnic social relations. Among those older than 65, lower language subscale score was associated with higher log-albuminuria (β = 0.12, 95% CI 0.03, 0.22). Among individuals with CKD, acculturation measures were not associated with control of cardiovascular risk factors. In conclusion, lower language acculturation was associated with a higher prevalence of CKD in individuals older than 65. These findings suggest that older individuals with lower language acculturation represent a high risk group for CKD.

•

Among Hispanics/Latinos, lower language acculturation was associated with a higher prevalence of chronic kidney disease in older individuals.

•

Based on our findings, older individuals with lower language acculturation represent a high-risk group for chronic kidney disease.

Eating Like a Rainbow: The Development of a Visual Aid for Nutritional Treatment of CKD Patients. A South African Project

Providing nutritional education for chronic kidney disease (CKD) patients in South Africa is complicated by several conditions: the population is composed of diverse ethnic groups, each with its own culture and food preferences; eleven languages are spoken and illiteracy is common in the lower socio-economic groups. Food preparation and storage are affected by the lack of electricity and refrigeration, and this contributes to a monotonous diet. In traditional African culture, two meals per day are often shared "from the pot", making portion control difficult. There is both under- and over-nutrition; late referral of CKD is common. Good quality protein intake is often insufficient and there are several misconceptions about protein sources. There is a low intake of vegetables and fruit, while daily sodium intake is high, averaging 10 g/day, mostly from discretionary sources. On this background, we would like to describe the development of a simplified, visual approach to the "renal diet", principally addressed to illiterate/non-English speaking CKD patients in Southern Africa, using illustrations to replace writing. This tool "Five steps to improve renal diet compliance", also called "Eating like a Rainbow", was developed to try to increase patients' understanding, and has so far only been informally validated by feedback from users. The interest of this study is based on underlining the feasibility of dietary education even in difficult populations, focusing attention on this fundamental issue of CKD care in particular in countries with limited access to chronic dialysis.

CKD Progression and Mortality among Hispanics and Non-Hispanics

Although recommended approaches to CKD management are achieved less often in Hispanics than in non-Hispanics, whether long-term outcomes differ between these groups is unclear. In a prospective longitudinal analysis of participants enrolled into the Chronic Renal Insufficiency Cohort (CRIC) and Hispanic-CRIC Studies, we used Cox proportional hazards models to determine the association between race/ethnicity, CKD progression (50% eGFR loss or incident ESRD), incident ESRD, and all-cause mortality, and linear mixed-effects models to assess differences in eGFR slope. Among 3785 participants, 13% were Hispanic, 43% were non-Hispanic white (NHW), and 44% were non-Hispanic black (NHB). Over a median follow-up of 5.1 years for Hispanics and 6.8 years for non-Hispanics, 27.6% of all participants had CKD progression, 21.3% reached incident ESRD, and 18.3% died. Hispanics had significantly higher rates of CKD progression, incident ESRD, and mean annual decline in eGFR than did NHW (P<0.05) but not NHB. Hispanics had a mortality rate similar to that of NHW but lower than that of NHB (P<0.05). In adjusted analyses, the risk of CKD progression did not differ between Hispanics and NHW or NHB. However, among nondiabetic participants, compared with NHB, Hispanics had a lower risk of CKD progression (hazard ratio, 0.61; 95% confidence interval, 0.39 to 0.95) and incident ESRD (hazard ratio, 0.50; 95% confidence interval, 0.30 to 0.84). At higher levels of urine protein, Hispanics had a significantly lower risk of mortality than did non-Hispanics (P<0.05). Thus, important differences in CKD progression and mortality exist between Hispanics and non-Hispanics and may be affected by proteinuria and diabetes.

Relationship between Health Literacy and Kidney Function

AIM

Low health literacy (HL) may contribute to poor self-management of chronic kidney disease (CKD) and poor kidney function. This study aimed to assess the relationship between HL and estimated glomerular filtration rate (eGFR).

METHODS

A cross-sectional observational study was conducted among consecutive eligible adult patients with CKD stages 1-4 attending an outpatient nephrology clinic. HL was assessed using Newest Vital Sign (NVS). eGFR was estimated using the Modification of Diet in Renal Disease equation. CKD self-management behaviour knowledge was assessed using a study instrument (CKD self-management knowledge (SMKT)).

RESULTS

One hundred fifty patients participated in the study (83% participation rate). The prevalence of high likelihood of limited HL was 32.7%. Participants' eGFRs ranged from 17 to 152 mL/min / 1.73 m(2) , with over 80% of the eGFRs below 60 mL/min / 1.73 m(2) . HL was associated with eGFR after controlling for all demographics except age, race and gender (which are included in eGFR equation) (P = 0.05). Every unit increase in NVS score was associated with a 1.9% increase (95% confidence interval = 0 to 3.86%) in eGFR (model R square = 0.23, P = 0.002), which remained significant after controlling for CKD-SMKT (P = 0.05; model R square = 0.28, P < 0.001). The relationship was non-significant after controlling for age, although it remained significant after controlling for other demographics including gender and race.

CONCLUSIONS

There is a small but significant association between HL and eGFR. Providers should use HL-tailored communication strategies in CKD patients. Larger multicentre studies are needed to substantiate this relationship.

Association Between Cognitive Impairment and Chronic Kidney Disease in Mexican Americans

Objectives

To analyze the association between chronic kidney disease (CKD) and mild cognitive impairment (MCI) in Mexican Americans and to determine whether there is a blood‐based proteomic profile linking CKD to MCI.

Design

Retrospective analysis of cohort study.

Setting

Health and Aging Brain among Latino Elders study.

Participants

Mexican Americans (N = 437, 105 men, 332 women).

Measurements

Data were analyzed to examine the link between estimated glomerular filtration rate (eGFR) and detailed neuropsychological functioning. Serum proteomic markers were also examined.

Results

Lower eGFR levels were associated with significantly poorer neuropsychological functioning across multiple domains. After adjusting for age, sex, education, and diabetes mellitus, participants with an eGFR less than 45 mL/min per 1.73 m² performed significantly worse than those with an eGFR from 45 to 59 mL/min per 1.73 m² or 60 mL/min per 1.73 m² and higher in processing speed (F = 14.1, P < .001), executive functioning (F = 4.5, P = .01), visuospatial skills (F = 4.8, P = .009), and global cognitive functioning (F = 6.2, P = .002). Participants with an eGFR less than 45 mL/min per 1.73 m² also performed significantly worse than those with an eGFR of 60 mL/min per 1.73 m² or greater on delayed memory (F = 3.8, P = .02). There was a trend toward lower eGFR levels being associated with greater risk of MCI (odds ratio (OR) = 2.4, 95% confidence interval (CI) = 0.91–6.1, P = .07), which was stronger for men (OR = 9.6, 95% CI = 1.3–74.3, P = .03). A serum proteomic profile consisting of Factor VII, interleukin‐10, C‐reactive protein, and fatty acid binding protein was 93% accurate in detecting CKD‐related MCI.

Conclusion

Lower eGFR was associated with significantly poorer neuropsychological functioning in Mexican Americans. A blood‐based profile was generated that was highly accurate in detecting CKD‐related MCI. A blood profile capable of predicting CKD‐related cognitive impairment would be of benefit for the design of clinical interventions.

Hypertension in minority populations: new guidelines and emerging concepts

Persistent disparities in hypertension, CKD, and associated cardiovascular disease have been noted in the United States among racial/ethnic minority groups. Overall, these disparities are largely mediated by social determinants of health. Yet, emerging data suggest additional biologic factors in racial/ethnic disparities in hypertension prevalence, complications, particularly CKD, and responses to treatment. Nevertheless, race is a social construct and not a physiologic concept, and ethnicity, federally defined as the binary "Hispanic/Latino" or "not Hispanic/Latino," is also imprecise. However, race/ethnicity categories may help interpret health-related data, including surveillance and research, and are important in ensuring that clinical trials remain generalizable to diverse populations. There is significant heterogeneity among prespecified groups and, perhaps, greater genetic differences within than between certain racial/ethnic groups. This review will explore hypertension epidemiology, pathophysiology, and management among the diverse and growing US minority groups, specifically African Americans and Hispanics because much less data are available across the wide spectrum of diverse populations. We will highlight the intersection of hypertension and increasingly prevalent CKD, particularly in African Americans. Finally, we propose multidimensional treatment approaches to hypertension among diverse populations, encompassing population, community, health system, and individual-based approaches.

Socioeconomic disparities in chronic kidney disease

CKD is a national public health problem that afflicts persons of all segments of society. Although racial/ethnic disparities in advanced CKD including dialysis-dependent populations have been well established, the finding of differences in CKD incidence, prevalence, and progression across different socioeconomic groups and racial and ethnic strata has only recently started to receive significant attention. Socioeconomics may exert both interdependent and independent effects on CKD and its complications and may confound racial and ethnic disparities. Socioeconomic constellations influence not only access to quality care for CKD risk factors and CKD treatment but may mediate many of the cultural and environmental determinants of health that are becoming more widely recognized as affecting complex medical disorders. In this article, we have reviewed the available literature pertaining to the role of socioeconomic status and economic factors in both non-dialysis-dependent CKD and ESRD. Advancing our understanding of the role of socioeconomic factors in patients with or at risk for CKD can lead to improved strategies for disease prevention and management.

Health Literacy and Medication Adherence Among Patients Treated in a Free Health Clinic: A Pilot Study

BACKGROUND

A patient's health literacy is not routinely assessed during visits with a health care provider. Since low health literacy is a risk factor for poor health outcomes, assessing health literacy should be considered as part of the standard medical workup.

OBJECTIVES

To evaluate the health literacy levels and medication adherence of patients treated by pharmacists in both the general medicine and the chronic care clinics at an urban free health clinic.

METHODS

Eligible patients from the free health clinic completed the Rapid Estimate of Adult Literacy in Medicine (REALM), a health literacy measurement tool, during their clinic visit in 2011. Medication adherence was self-reported by the patients.

RESULTS

A total of 100 patients participated (mean age = 48). The majority of participants were female (56%) and white (55%). Most (64%) of the patients scored at a high school reading level according to REALM. Only 21% of participants read at a seventh- to eighth-grade level. Overall medication adherence rate was 73%. Forgetting to take medication was the most popular reason given for nonadherence.

CONCLUSION

Disease state and adherence were significantly related in patients with HIV/AIDS and hypertension. Patient's ethnicity was significantly associated with literacy levels (P < .05). Although patients' literacy levels were not significantly associated with self-reported adherence in this population, availability of a patient's baseline health literacy level as a part of the medical record may help clinicians to individualize their interaction based on the patient's health literacy level in order to achieve better health outcomes, including improved medication adherence, especially for underserved populations.

Mapping end-stage renal disease (ESRD): spatial variations on small area level in northern France, and association with deprivation

BACKGROUND

Strong geographic variations in the incidence of end-stage renal disease (ESRD) are observed in developed countries. The reasons for these variations are unknown. They may reflect regional inequalities in the population's sociodemographic characteristics, related diseases, or medical practice patterns. In France, at the district level, the highest incidence rates have been found in the Nord-Pas-de-Calais region. This area, with a high population density and homogeneous healthcare provision, represents a geographic situation which is quite suitable for the study, over small areas, of spatial disparities in the incidence of ESRD, together with their correlation with a deprivation index and other risk factors.

METHODS

The Renal Epidemiology and Information Network is a national registry, which lists all ESRD patients in France. All cases included in the Nord-Pas-de-Calais registry between 2005 and 2011 were extracted. Adjusted and smoothed standardized incidence ratio (SIR) was calculated for each of the 170 cantons, thanks to a hierarchical Bayesian model. The correlation between ESRD incidence and deprivation was assessed using the quintiles of Townsend index. Relative risk (RR) and credible intervals (CI) were estimated for each quintile.

RESULTS

Significant spatial disparities in ESRD incidence were found within the Nord-Pas-de-Calais region. The sex- and age-adjusted, smoothed SIRs varied from 0.66 to 1.64. Although no correlation is found with diabetic or vascular nephropathy, the smoothed SIRs are correlated with the Townsend index (RR: 1.18, 95% CI [1.00-1.34] for Q2; 1.28, 95% CI [1.11-1.47] for Q3; 1.30, 95% CI [1.14-1.51] for Q4; 1.44, 95% CI [1.32-1.74] for Q5).

CONCLUSION

For the first time at this aggregation level in France, this study reveals significant geographic differences in ESRD incidence. Unlike the time of renal replacement care, deprivation is certainly a determinant in this phenomenon. This association is probably independent of the patients' financial ability to gain access to healthcare.

Status of cardiovascular disease and stroke in Hispanics/Latinos in the United States: a science advisory from the American Heart Association

BACKGROUND AND PURPOSE

This American Heart Association (AHA) scientific statement provides a comprehensive overview of current evidence on the burden cardiovascular disease (CVD) among Hispanics in the United States. Hispanics are the largest minority ethnic group in the United States, and their health is vital to the public health of the nation and to achieving the AHA's 2020 goals. This statement describes the CVD epidemiology and related personal beliefs and the social and health issues of US Hispanics, and it identifies potential prevention and treatment opportunities. The intended audience for this statement includes healthcare professionals, researchers, and policy makers.

METHODS

Writing group members were nominated by the AHA's Manuscript Oversight Committee and represent a broad range of expertise in relation to Hispanic individuals and CVD. The writers used a general framework outlined by the committee chair to produce a comprehensive literature review that summarizes existing evidence, indicate gaps in current knowledge, and formulate recommendations. Only English-language studies were reviewed, with PubMed/MEDLINE as our primary resource, as well as the Cochrane Library Reviews, Centers for Disease Control and Prevention, and the US Census data as secondary resources. Inductive methods and descriptive studies that focused on CVD outcomes incidence, prevalence, treatment response, and risks were included. Because of the wide scope of these topics, members of the writing committee were responsible for drafting individual sections selected by the chair of the writing committee, and the group chair assembled the complete statement. The conclusions of this statement are the views of the authors and do not necessarily represent the official view of the AHA. All members of the writing group had the opportunity to comment on the initial drafts and approved the final version of this document. The manuscript underwent extensive AHA internal peer review before consideration and approval by the AHA Science Advisory and Coordinating Committee.

RESULTS

This statement documents the status of knowledge regarding CVD among Hispanics and the sociocultural issues that impact all subgroups of Hispanics with regard to cardiovascular health. In this review, whenever possible, we identify the specific Hispanic subgroups examined to avoid generalizations. We identify specific areas for which current evidence was less robust, as well as inconsistencies and evidence gaps that inform the need for further rigorous and interdisciplinary approaches to increase our understanding of the US Hispanic population and its potential impact on the public health and cardiovascular health of the total US population. We provide recommendations specific to the 9 domains outlined by the chair to support the development of these culturally tailored and targeted approaches.

CONCLUSIONS

Healthcare professionals and researchers need to consider the impact of culture and ethnicity on health behavior and ultimately health outcomes. There is a need to tailor and develop culturally relevant strategies to engage Hispanics in cardiovascular health promotion and cultivate a larger workforce of healthcare providers, researchers, and allies with the focused goal of improving cardiovascular health and reducing CVD among the US Hispanic population.

A systematic evaluation of websites offering information on chronic kidney disease

In this study, we described the content and characteristics of 40 non-proprietary websites offering information about chronic kidney disease (CKD) and evaluated their information quality using the DISCERN scale and readability using Flesch Reading Ease and Flesch-Kincaid grade level. The areas in which the websites scored the lowest on the DISCERN scale were whether the website discussed knowledge gaps, presented balanced information, and was clear about the information source. Websites that rated higher quality on the DISCERN scale were more difficult to read. The quality and readability of many websites about CKD to be used as meaningful educational resources for patients who desire to learn more about CKD and treatment options remain inadequate.

Limited health literacy is associated with low glomerular filtration in the Chronic Renal Insufficiency Cohort (CRIC) study

Background: Low health literacy in the general population is associated with increased risk of death and hospitalization. The evaluation of health literacy in individuals with predialysis chronic kidney disease (CKD) is limited. Methods: We conducted a cross-sectional study to evaluate the associations of limited health literacy with kidney function and cardiovascular disease (CVD) risk factors in 2,340 non-Hispanic (NH) Whites and Blacks aged 21 – 74 years with mild-to-moderate CKD. Limited health literacy was defined as a Short Test of Functional Health Literacy in Adults (STOFHLA) score ≤ 22. Outcomes evaluated included estimated glomerular filtration rate (eGFR), 24-hour urine protein excretion, and CVD risk factors. Results: The prevalence of limited health literacy was 28% in NH-Blacks and 5% in NH-Whites. Compared with participants with adequate health literacy, those with limited health literacy were more likely to have lower eGFR (34 vs. 42 mL/min/1.73 m²); higher urine protein/24-hours (0.31 vs. 0.15 g); and higher self-reported CVD (61 vs. 37%); and were less likely to have BP < 130/80 mmHg (51 vs. 58%); p ≤ 0.01 for each comparison. After adjustment, limited health literacy was associated with self-reported CVD (OR 1.51, 95% CI 1.13 – 2.03) and lower eGFR (β –2.47, p = 0.03). Conclusion: In this CKD cohort, limited health literacy was highly prevalent, especially among NH-Blacks, and it was associated with lower eGFR and a less favorable CVD risk factor profile. Further studies are needed to better understand these associations and inform the development of health literacy interventions among individuals with CKD.

Iothalamate versus estimated GFR in a Hispanic-dominant pediatric renal transplant population

BACKGROUND

Accurate knowledge of glomerular filtration rate (GFR) is essential to the practice of nephrology. Routine surveillance of GFR is most commonly executed using estimated GFR (eGFR) calculations, most often from serum creatinine measurements. However, cystatin C-based equations have demonstrated earlier sensitivity to decline in renal function. The literature regarding eGFR from cystatin C has few references that include transplant recipients. Additionally, for most of the published eGFR equations, patients of Hispanic ethnicity have not been enrolled in sufficient numbers.

METHODS

The applicability of several eGFR equations to the pediatric kidney transplant population at our center were compared in the context of determining whether Hispanic ethnicity was associated with equation performance.

RESULTS

Updated Schwartz, CKiD, and Zappitelli eGFR estimation equations demonstrated the highest correlations.

CONCLUSIONS

The authors recommend further prospective investigations to validate and identify factors contributing to these findings.

Type 2 translational research for CKD

Strategies to effectively treat people with CKD have been identified by conventional clinical research. Despite this evidence, awareness, screening, detection, diagnosis, risk factor control, treatment, and outcomes remain substandard. Translating clinical evidence into actionable measures that reduce the burden of CKD is a pressing need. Expansion from a "bench-to-bedside" paradigm (conventional type 1 translation) to research that encompasses "clinic and community" is the core concept of type 2 translation. Specifically, this is the discipline of identifying factors and using strategies that lead to adoption, maintenance, and sustainability of science-based interventions in practice. This review identifies key elements of type 2 translational research and highlights the current scope of this type of research for CKD. For type 2 translation to achieve the goals of providing high-quality care and better health outcomes, key facilitators (e.g., theory-based frameworks, adaptable interventions, and inclusion of sustainability and evaluation metrics) and essential elements (e.g., multidisciplinary team care, health information technology, and stakeholder engagement) must be integrated. The National Institute of Diabetes and Digestive and Kidney Diseases recently funded five proposals that aim to improve outcomes for people with CKD, focusing on diverse components of the healthcare continuum: patient safety and transitions; delivery of high-quality, evidence-based CKD care; and elimination of disparities. The need for type 2 translational research in CKD is urgent because of preventable human suffering and unsustainable costs of providing care. Focus on the theory, framework, and approaches we have suggested may help us meet that challenge.

Diabetes and its comorbidities--where East meets West

Fetal programming associated with in utero exposure to maternal stress is thought to alter gene expression, resulting in phenotypes that promote survival in a pathogen-rich and nutrient-poor environment but substantially increase the risk of cardiovascular, metabolic and renal disorders (such as diabetes mellitus) in adults with obesity. These (epi)genetic phenomena are modified by environmental and socioeconomic factors, resulting in multiple subphenotypes and clinical consequences. In individuals from areas undergoing rapid economic development, which is associated with a transition from communicable to noncommunicable diseases, an efficient innate immune response can exaggerate obesity-associated inflammation. By contrast, in individuals with a genetic predisposition to autoimmune or monogenic diabetes mellitus, obesity can lead to atypical presentation of diabetes mellitus, termed 'double diabetes mellitus'. The increasingly young age at diagnosis of diabetes mellitus in developing countries results in prolonged exposure to glucolipotoxicity, low-grade inflammation and increased oxidative stress, which put enormous strain on pancreatic β cells and renal function. These conditions create a metabolic milieu conducive to cancer growth. This Review discusses how rapid changes in technology and human behaviour have brought on the global epidemic of metabolic diseases, and suggests that solutions will be based on using system change, technology and behavioural strategies to combat this societal-turned-medical problem.

ACE inhibitor and ARB medication use among Medicaid enrollees with diabetes

OBJECTIVE

To examine ace-inhibitor (ACEI) and angiotensin receptor blockers (ARB) prescription and adherence patterns by race in diabetic public aid recipients.

DESIGN, PARTICIPANTS, AND MEASURES

We analyzed prescription records of 27,529 adults aged 18-64 with diabetes who had at least one clinical indication for receiving an ACEI/ ARB prescription and were enrolled in the State of Illinois public aid program during 2007. We calculated proportion of days covered (PDC) to assess adherence. Multivariate models adjusted for age, sex, ACEI/ARB indication, and any significant interaction terms.

RESULTS

Only 47.4% of individuals with at least one indication for ACEI/ARB had filled an ACEI/ARB prescription. African American men were more likely than Caucasian men to ever fill an ACEI/ARB prescription (adjusted odds ratio, [AOR] [95% CI] 1.69 [1.55-1.83]). Hispanic English and Spanish speaking men were also more likely than Caucasian men to ever fill an ACEI/ARB prescription (AOR [95% CI] 1.37 [1.16-1.62] and 1.27 [1.05-1.53], respectively). Similarly, African American and Hispanic English and Spanish speaking women were more likely than Caucasian women to ever fill an ACEI/ARB prescription (AOR [95% CI] 1.70 [1.59-1.81], 1.55 (1.36-1.76), and 1.98 (1.73-2.28), respectively. However, African Americans and Hispanics were less likely than Caucasians to achieve a PDC> or =80%. Compared to Caucasians, Hispanic Spanish speakers were the least likely to be adherent (AOR [95% CI] .49 [.41-.58]). Furthermore, older individuals were more likely to achieve a PDC> or =80% than younger individuals.

CONCLUSION

African Americans and Hispanics with diabetes receiving public aid in Illinois were more likely than Caucasians to have filled at least one ACEI/ARB prescription. However, they were less adherent with these medications. Future studies should assess barriers to medication adherence in this population.

NUTORC-a transdisciplinary health services and outcomes research team in transplantation

The field of solid organ transplantation has historically concentrated research efforts on basic science and translational studies. However, there has been increasing interest in health services and outcomes research. The aim was to build an effective and sustainable, inter- and transdisciplinary health services and outcomes research team (NUTORC), that leveraged institutional strengths in social science, engineering, and management disciplines, coupled with an international recognized transplant program. In 2008, leading methodological experts across the university were identified and intramural funding was obtained for the NUTORC initiative. Inter- and transdisciplinary collaborative teams were created across departments and schools within the university. Within 3 years, NUTORC became fiscally sustainable, yielding more than tenfold return of the initial investment. Academic productivity included funding for 39 grants, publication of 60 manuscripts, and 166 national presentations. Sustainable educational opportunities for students were created. Inter- and transdisciplinary health services and outcomes research in transplant can be innovative and sustainable.

Usability of a CKD educational website targeted to patients and their family members

BACKGROUND AND OBJECTIVES

Web-based technology is critical to the future of healthcare. As part of the Safe Kidney Care cohort study evaluating patient safety in CKD, this study determined how effectively a representative sample of patients with CKD or family members could interpret and use the Safe Kidney Care website (www.safekidneycare.org), an informational website on safety in CKD.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Between November of 2011 and January of 2012, persons with CKD or their family members underwent formal usability testing administered by a single interviewer with a second recording observer. Each participant was independently provided a list of 21 tasks to complete, with each task rated as either easily completed/noncritical error or critical error (user cannot complete the task without significant interviewer intervention).

RESULTS

Twelve participants completed formal usability testing. Median completion time for all tasks was 17.5 minutes (range=10-44 minutes). In total, 10 participants had greater than or equal to one critical error. There were 55 critical errors in 252 tasks (22%), with the highest proportion of critical errors occurring when participants were asked to find information on treatments that may damage kidneys, find the website on the internet, increase font size, and scroll to the bottom of the webpage. Participants were generally satisfied with the content and usability of the website.

CONCLUSIONS

Web-based educational materials for patients with CKD should target a wide range of computer literacy levels and anticipate variability in competency in use of the computer and internet.
