Abstract
This study examines the association between health literacy and adherence to low-salt diet practices among individuals with hypertension. Health literacy is the ability of individuals to understand and utilize health information. We surveyed 238 patients with hypertension from a primary care clinic in Charlotte, NC. We assessed health literacy and self-reported low-salt diet. Logistic regression was used to model the relationship between health literacy and low-salt diet adherence. Respondents were primarily female (67.3%) and black (80%). Black Americans were less likely to have adequate health literacy as compared to white Americans (21.8% vs. 55.8%). The study found no association between adequate health literacy and adherence to a low-salt diet (OR = 1.06, 95% CI: 0.36-3.10) after adjusting for confounders. This study addresses the conflicting findings for health literacy in two related areas: chronic illness self-care, and nutrition/diet skills. Additional research is warranted among black Americans given their increased risk of hypertension, low rates of diet adherence and previous findings of positive associations between health literacy and nutrition skills.

Abstract Background Although the Dietary Approaches to Stop Hypertension (DASH) diet is an accepted nonpharmacologic treatment for hypertension, little is known about what patient characteristics affect dietary adherence and what level of adherence is needed to reduce blood pressure (BP). Objective Our aim was to determine what factors predict dietary adherence and the extent to which dietary adherence is necessary to produce clinically meaningful BP reductions. Design Ancillary study of the ENC...

: This integrative review identifies barriers to implementing the Dietary Approaches to Stop Hypertension (DASH) diet in hypertensive African American women. Databases were searched for original research published between 1999 and 2009. Barriers included clinicians' low adherence to nutritional counseling and patients' lack of knowledge regarding nutrition and the consequences of hypertension.

Abstract Background Although health literacy has been a public health priority area for more than a decade, the relationship between health literacy and dietary quality has not been thoroughly explored. Objective To evaluate health literacy skills in relation to Healthy Eating Index (HEI) scores and sugar-sweetened beverage (SSB) consumption while accounting for demographic variables. Design Cross-sectional survey. Participants/setting A community-based proportional sample of adults residing in ...

Background A comprehensive understanding of the self-care activities that contribute to blood pressure control may explain health disparities experienced by African Americans with hypertension. This study assessed the prevalence of self-care activities among African Americans with high blood pressure and examined differences between adherers and nonadherers to self-care activities. Methods Interviews were conducted with 186 African Americans. Self-care activities were measured using the H-SCALE ...

Purpose: Difficulties in identifying and caring for patients with limited health literacy have prompted interest in clinical screening to assess health literacy. Little agreement exists, however, on the utility of such screening. In this case study we explore the business and clinical cases for screening for health literacy using the Newest Vital Sign (NVS), a brief instrument specifically developed for use in primary care settings. Methods: Data were collected in 2008 in the Morehouse School of...

Abstract Objective: This study assessed associations among health literacy, diabetes knowledge, self-care, and glycemic control in a low income, predominately minority population with type 2 diabetes. Methods: One hundred twenty-five adults with diabetes were recruited from a primary care clinic. Subjects completed validated surveys to measure health literacy, diabetes knowledge, and self-care (medication adherence, diet, exercise, blood sugar testing, and foot care). Hemoglobin A1c values were ...

Abstract Background: Although limited health literacy is a barrier to disease management and has been associated with poor glycemic control, the mechanisms underlying the relationships between health literacy and diabetes outcomes are unknown. We examined the relationships between health literacy, determinants of diabetes self-care, and glycemic control in adults with type 2 diabetes. Methods: Patients with diabetes were recruited from an outpatient primary care clinic. We collected information ...

There were statistically • significant trends in intake of the macronutrients: average carbohydrate intake decreased and average protein intake increased in both men and women. The Surgeon General’s recent call for renewed efforts to address the high prevalence of obesity in the U.S. adult population highlights the need for better understanding of trends in consumption of energy and the macronutrients protein, carbohydrate, and fat (1). The National Health and Nutrition Examination Survey (NHANE...

Abstract Background While many instruments have been developed, validated, and used to assess health literacy skills, their use and appropriateness among patients with cardiovascular diseases (CVDs) are not widely studied. Objective To identify, appraise, and synthesize available health literacy assessment instruments used in patients with CVDs. Methods Electronic databases were searched for studies that used validated measures to assess health literacy in patients with CVDs. Included studies we...

Abstract Objective Synthesize quantitative empirical evidence on the role of health literacy in predicting adherence to dietary recommendations. Methods A systematic search of 13 online databases resulted in 1498 articles eligible for screening. Of those, 20 met the predefined inclusion criteria and, together with 6 studies retrieved from their reference lists, were included for review. Screening of full-texts, data extraction and quality appraisal were independently performed by two reviewers. ...
