- OBJECTIVES
The main objectives of this study are to identify the factors associated with hypertension control and to determine the influencing factors associated with antihypertensive therapy. METHODS: The study was conducted on 107 subjects who participated in the 1999 and 2002 Gwacheon Study and who had had uncontrolled hypertension (systolic > or=140 or diastolic > or= 90mmHg) in 1999. We compared the characteristics of the controlled and uncontrolled hypertensive group and investigated the characteristics of those taking antihypertensive medication. Univariate associations between hypertension control and its characteristics and the association between antihypertension treatment and its characteristics were tested with x2-test. We also performed logistic regression analysis. RESULTS: The participants who had their blood pressure checked within 6 months before their first measurement and those who had taken the antihypertensive medication showed significantly better hypertension control during the follow-up. The multivariate analysis showed that baseline antihypertensive therapy was the most important determinant factor of hypertension control during the follow-up. Socioeconomic level and life style did not affect hypertension control when controlled by the treatment variable in this study. The factors associated with antihypertensive therapy at follow-up were previous antihypertensive therapy, old age, and high educational level. CONCLUSIONS: Those who received antihypertensive therapy and those who had their blood pressure re-checked within 6 months both showed well controlled hypertension. The subjects with high educational level complied well with the antihypertensive regimen, but those in their forties did not.

- OBJECTIVES
To identify the factors related to awareness, treatment, and control of hypertension in a Gwacheon population. METHODS: This study surveyed 1, 176 Gwacheon residents older than 40 years, and measured blood pressure using a standardized guideline in 1999. The study subjects were 473 adults (175 males, 298 females) with hypertension defined as a systolic blood pressure > or= 140 mmHg, diastolic blood pressure > or= 90 mmHg or reported treatment with antihypertensive medications. Information on awareness, treatment, and control of hypertension, and sociodemographic and health-related factors was collected through person-to-person interviews with a structured questionnaire. RESULTS: Overall, 252 (53.3%) of hypertensive subjects were aware of their condition, of whom as many as 193 (76.6%) were being treated, and 81 (42.0%) had their blood pressure controlled at the recommended level (< 140/90 mmHg). However, of the 473 subjects found to have hypertension, only 40.8% were being treated, and 17.1% were under control. There were no significant differences in the proportions of awareness, treatment, and control of hypertension. In multiple logistic regression models, awareness of hypertension was positively associated with age and family history of hypertension in females. Control of hypertension was also positively associated with having a partner and marital status in females. CONCLUSION: These findings demonstrate that much greater efforts on improving awareness, treatment, and control of hypertension are needed, even in urban community settings, considering related factors such as age, family history, and marital status. However, these factors should be further investigated for their causal relationship.
