Health Literacy And The Level Of Hypertension In Urban Latinos, Marlene Rosetta Glashen

Walden Dissertations and Doctoral Studies

Health literacy (HL) plays a significant role in health care communication and patient compliance. Low health literacy leads to noncompliance with health instructions, poor health choices, failure to participate in recommended health screenings, frequent hospitalizations, and higher health care costs. Using the health belief model (HBM) as the conceptual framework, this quantitative, cross-sectional study addresses a gap in the literature related to the research questions of this study. The research questions are: (a) Is there a relationship between HL and the level of hypertension (HTN) in hypertensive urban Latinos?, and (b) Will HL predict the level of control of HTN …
