Perception of stress, depression, hypertension and myocardial infarction as predictors of adherence to hypertension drug treatment.

This survey was performed to determine the relationship between the adherence to hypertension drug treatment and the perception of stress, depression, hypertension, and myocardial infarction. 300 patients with uncomplicated hyperten- sion from Rijeka, Croatia, were included (131 women, 169 men, mean age 53.5 years). Adherence to hypertension drug treatment as criterion, and the perception of stress, depression hypertension and myocardial infarction as prediclors were determined by self-assessment. Collected data were analysed using factor analysis, regression analysis, Kolmogorov-Smirnov test, chi2-test and t-test. The statistical significance was set at a probability rate of less than 5% (p < 0.05). 45.09% of women (p=0.479), and 64.08% of men (p = 0.032) were motivated to take antihypertensives. 55.79% of women (p = 0.382) and 64.78% of men (p = 0.028) had sufficient knowledge about drug treatment of hypertension. The positive predictors of motivation for taking antihypertensives were physiological disturbances and perceived potency of hypertension and the negative were perceived helplessness in stress control and negative thoughts and emotions. The positive predictors of knowledge about taking antihypertensives were perceived helplessness in stress control, perceived potency of hypertension and myocardial infarction and the negative predictors were perceived self-efficacy in stress control, physiological disturbances and evaluation of hypertension. Both the motivation as well as the knowledge about taking antihypertensives should be improved, especially in women. The perception of stress, depression, hypertension and myocardial infarction can be used to predict adherence to hypertension drug treatment.
