Abstract
OBJECTIVE: To analyze the association between health literacy and the adherence to the pharmacological treatment of Brazilians with arterial hypertension. METHODS: Cross-sectional study with 234 participants who responded an on-line sociodemographic and clinical characterization questionnaire, in addition to evaluation of health literacy and of the adherence to their pharmacological treatment. Data were analyzed using descriptive statistics and difference and correlation tests. RESULTS: People with post-graduation, who were actively working and did not smoke, had better health literacy results. Elders and those who were retired or lived on government subsidies adhered better to the medication treatment. There was a correlation between the numerical dimension (rs=0.189; p=0.004) and the global health literacy result (r2=0.170; p=0.009) with the adherence. CONCLUSIONS: A better numerical and global understanding of health literacy was associated with better adherence to arterial hypertension medication treatment.
