Factors Affecting Adherence to Antihypertensive Medication / 가정의학회지

BACKGROUND: Hypertension is a major contributor to the global disease burden of cardiovascular and cerebrovascular disease. The aim of this study was to determine demographic and clinical factors associated with adherence to antihypertensive medication. METHODS: From August 2012 to February 2015, we recruited 1,523 Korean patients with hypertension who visited family physicians. The study was conducted in 24 facilities located in urban and metropolitan areas. Of these facilities, two were primary care clinics and 22 were level 2 or 3 hospitals. Adherence was assessed using the pill count method; a cut-off value of 80% was used as the criterion for good adherence. Sociodemographic and lifestyle factors were compared between the adherent and nonadherent groups using the chi-square test for categorical variables and t-test for continuous variables. Binary logistic regression analysis was performed with medication adherence as the outcome variable. RESULTS: Of the 1,523 patients, 1,245 (81.7%) showed good adherence to antihypertensive medication. In the multivariate logistic analysis, age ≥65 years, exercise, treatment in a metropolitan-located hospital, being on ≥2 classes of antihypertensive medication and concomitant medication for diabetes, and a family history of hypertension or cardiovascular diseases were associated with good adherence. Patients who had a habit of high salt intake were less adherent to medication. CONCLUSION: Multiple classes of antihypertensive medications, concomitant medication, and exercise were associated with good adherence to antihypertensive medication, and high salt intake was associated with poor adherence to antihypertensive medication. These factors should be considered to improve hypertension control.

Examinees' Knowledge of the Result Form of Korean National Health Examination

BACKGROUND: Cardiovascular diseases related mortality attributes to approximately one fourth of mortality in Korea, and management of chronic diseases is essential for the prevention of cardiovascular diseases. Through the health screening program, early detection and prevention of chronic disease are made possible, and this will improve the health status of examinees. In the current national health examination (NHE), counseling and continuous management after NHE have not been properly made. We aimed to investigate examinees' knowledge of the result form of NHE in order to find the ways of improvement. METHODS: We recruited 120 examinees, who have undergone general health examination and life turning point health examination (LTPHE), and conducted survey from January 7, 2016 to January 26, 2016. Participants answered questionnaires regarding demographic characteristics, health screening related factors, and their knowledge and attitude towards NHE. Answers were converted to Likert scale, and student t-test, one-way ANOVA, and linear regression models were used for the analyses. RESULTS: Examinees' knowledge of the result form was lowest in the blood test category. When age and type of institution were adjusted, the examinees in their 60s had significantly lower knowledge of all the categories of result forms except urine test in comparison to the younger examinees. When type of institutions were compared, examinees, who had undergone NHE in health screening clinics, had significantly lower knowledge of several categories of result forms in comparison to those who had undergone NHE in private clinics and general hospitals. Examinees' knowledge of the LTPHE result form was lowest in categories of “mild cognitive impairment and dementia” and “fall down and voiding difficulty.” CONCLUSIONS: The result form of NHE should be revised so that examinees in old age can easily understand. Examinees' knowledge of the result form was lower in health screening clinic; thus, quality of health screening clinic should be improved for continuous care after NHE.
