Poor medication adherence is a major contributor to inadequate BP control, and is associated
with 125,000 deaths annually. Translation of adherence interventions to community-based
primary care practices where majority of Latino patients receive care is non-existent. Thus,
the development of tailored interventions targeted at improving medication adherence in the
Latino population is needed in order to address the racial disparities in BP control between
Latinos and whites. This proposal provides a unique opportunity to address this gap in the
literature. Using a randomized control design (RCT), the study will evaluate the effect of a
culturally tailored, practice-based intervention on medication adherence in 148 high-risk
Latino patients with uncontrolled HTN. To facilitate translation into routine practices, the
intervention will be integrated into the clinic's electronic medical record (EMR) system, and
will be delivered by trained, bilingual Health Coaches.

Latinos are the fastest growing ethnic group of the U.S. with a growth rate of 43% compared
to 23% among whites over the past decade. This increase is four times the nation's 9.7%
growth rate, and accounts for more than half of the total U.S. population increase of 27.3
million during this period. This growth is accompanied by a significant increase in
cardiovascular disease (CVD)-related morbidity and mortality. Despite increasing trends in
the awareness and treatment of hypertension (HTN) among all groups, Latinos have the lowest
blood pressure (BP) control rates in the U.S. Although barriers to optimal HTN control such
as poor access, and low awareness have been used to explain the disparities in BP control
between Latinos and whites, BP control rates remain lower among Latinos who receive treatment
compared to whites. This enigma may be explained by the disproportionately poorer adherence
to prescribed antihypertensive medications among Latinos compared to whites. Poor medication
adherence is a major contributor to inadequate BP control, and is associated with 125,000
deaths annually. Despite over 30 years of research dedicated to understanding adherence
behaviors in hypertensive patients, data in Latino patients is scant. More importantly,
