RESUMO
Background: Elevated blood pressure (BP) is one of the leading causes for developing major cardiovascular events and still represents a major public health challenge worldwide. We aimed to provide data on predictors of poor adherence to medication in hypertensive patients in Serbia. Methods: Observational, analytical study was undertaken at a group of 388 patients who refilled their medications in the Pharmacy Institution, "Apoteka Kragujevac", Kragujevac, Serbia between Jan and Mar 2019. Afterward, we conducted a case-control study to evaluate the influence of the variables associated with the adherence. We used a self-developed questionnaire and SF-36 to assess the influence of the quality of life on medication adherence. Results: Results revealed four independent predictors of non-adherence: increased number of medications, living in a city, forgetfulness of the dosing regimen and low energy. The odds of non-adherence were the highest among the participants living in the city and the low energy was the only factor inversely associated with the level of non-adherence. Conclusion: Many factors were associated with the non-adherence to medication. Further studies are needed to find the most appropriate protocol to promote adherence. The four risk factors (increased number of medications, living in a city, forgetfulness of the dosing regimen and low energy) are associated with non-adherence in adult hypertensive patients.
