Background: Medication adherence in hypertension is the most important to control blood pressure and prevent majorcomplications. The purpose of this study was to identify factors affecting medication adherence and to examine the relationshipbetween medication adherence and blood pressure control in Korea.
Methods: This study used data from the 7th Korea national health and nutrition examination survey (2016?2018) of the Korea DiseaseControl and Prevention Agency. We selected 4,063 hypertensive patients from the data. And we choose socio-demographic, healthbehavior, healthcare utilization, and severity characteristics as hypertensive patient characteristics.
Results: Of the patients with hypertension, 92.3% had shown adherence to medication as of 2016?2018 and shows variationaccording to the characteristic of patients. The cases with male, under 50 years old, urban area, single household, unmet medicalservices, less than 5 years of hypertension duration, no comorbidities (diabetes mellitus, myocardial infarction) showed significantlylow medication adherence. After adjusting for confounders, adherent patients tended to have lower current systolic blood pressure(β=-10.846, p<0.001) and diastolic blood pressure (β=-5.018, p<0.001) than nonadherent patients. And, adherent patients increasedthe control odds of blood pressure compared with nonadherent patients (odds ratio, 3.02; 95% confidence interval, 2.21-4.12).
Conclusion: This study confirmed that adherence to antihypertensive drugs was effective in controlling blood pressure. In order tomore actively manage hypertensive patients at the national level, it is necessary to make an effort to improve the medicationcompliance of nonadherent groups, such as early-diagnosis patients, young patients under 50 years of age, and patients living alone.
