Abstract

Objective:

To identify the association between socioeconomic, personal and health care factors, with inadequate blood pressure control.

Method:

Cross sectional, descriptive study, of 392 hypertensive individuals, randomly and proportionally selected from among 23 registered in the Basic Health of a city in Southern Brazil. Data were collected from homes between December 2011 and March 2012, using a semistructured questionnaire.

Results:

Almost half of the respondents had inadequate blood pressure control, which was associated with age less than 60 years; Non adherence to pharmacotherapy; failure to attend scheduled appointments, and; use of three or more antihypertensive drugs.

Conclusion:

Among the actions to improve blood pressure control in people with hypertension, the health care team needs to create strategies that encourage attendance at appointments, scheduled and simplify the treatment regimen. Such activities should focus particularly on the elderly.
