[Hypertension from the perspective of a low-income population: an exploratory study of knowledge, attitudes, and practices].

Knowledge, attitudes, and behaviors related to high blood pressure among adults in a low-income community in Caucaia, Ceará, Brazil, as well as factors influencing their attitudes toward behavioral risk factors (smoking, alcohol consumption, salt and fat consumption, and lack of physical exercise) were studied. A total of 228 individuals were interviewed using a structured interview protocol. Thirteen focus groups provided a more in-depth analysis of attitudes. According to the findings, the reasons behind behaviors and attitudes are linked to emotions and socioeconomic issues. Behavioral changes involve giving up certain pleasures, for people who are struggling to survive in living conditions imposed by poverty. Living in poverty interferes with the possibility of behavioral change.
