Introduction:

therapeutic adherence is a multifactorial problem that has generated the interest of many researchers worldwide.

Objective:

to determine adherence to antihypertensive therapy in older adult patients and the factors associated with no adherence.

Materials and methods:

a longitudinal descriptive study was carried out in hypertensive elderly patients belonging to the South Community Polyclinic, in the municipality of Moron, in the province of Ciego de Avila. The adherence to treatment was evaluated by the Martín-Bayarre-Grau questionnaire and the level of knowledge of the disease by the Batalla test. The causes associated with adherence problems in these patients were identified.

Results:

non-adherence to antihypertensive therapy predominated in 62%. Partial adherence was found to be 22%. Adherence problems prevailed in women aged 60-69 years. Multiple causes related with the patient were detected, such as forgetfulness (48.4%), non-availability of medicines (25.8%) and relief of symptoms (16.1%). Among other causes, the low level of knowledge on the disease and the presence of comorbidities were detected.

Conclusions:

a predominance of adherence to antihypertensive treatment in older adults was evidenced. Its main causes were the forgetfulness of taking the medicine, the non-availability of medicines, the lack of knowledge about the disease and the presence of comorbidities.
