BackgroundIn Brazil, the prevalence of systemic arterial hypertension (SAH) is
approximately 30% of the total population. In 2010, SAH was the cause of
death of about 9.4 million people worldwide. A healthy dietary pattern is
important to maintain proper blood pressure levels and, consequently,
disease control.ObjectivesTo describe the knowledge and practices of hypertensive patients cared for at
a public hypertension outpatient clinic, and its relationship with
high-sodium food.MethodsWe applied a questionnaire to patients with questions related to
sociodemographics, dietary pattern, frequency of ingestion of certain foods,
and knowledge about their own disease.ResultsWe studied 221 patients, 56.1% of whom were women, and 53.8% had only
elementary education. Their mean age was 57.7 ±13.5 years, and 75.6%
of them reported having high blood pressure, and 11.3%, diabetes mellitus.
Regarding dietary pattern, 62% used ready-to-use seasonings, but 94.1%
reported not adding extra salt to their ready meals. Regarding patients'
knowledge about high-sodium foods and SAH, only 8 patients had 100% of right
answers, 37 patients had 73.8%, and 42 patients, 57% of right answers.ConclusionKnowledge about SAH prevention and high-sodium foods was insufficient. Based
on this study's findings, more effective educational strategies targeted at
this population can be developed.
