Abstract

Hypertension is one of the most serious health problems in Korea. The purpose of this paper is to identify factors associated with self-reported nonadherence to an antihypertensive regimen. The data were obtained from the Korean Medical Panel 2008 and 2009 database, which were surveyed by the Korea Institute for Health and Social Affairs and National Health Insurance. We analyzed 5324 patients using multivariate logistic regression models. Self-reported nonadherence was used as a dependent variable and demographic, socioeconomic, and health status were included as independent variables to investigate the associated factors. Among the patients who were diagnosed with hypertension, 13.2% did not take their medicine as prescribed. Age and education attainment level were statistically significant. Younger and lower educational attainment groups were less likely to adhere to medication regimens and showed a tendency not to take their medicine as prescribed. There were no statistically significant variables in terms of health status. Our findings suggest that nurses in clinical and community settings should pay more attention to hypertensive patients who are young and less educated.
