  • Hypertension is a well-known risk factor for cardiovascular disease. Previous studies have shown that changes in diet and lifestyle factors can prevent the development of hypertension, but the combined effects of these modifiable factors on hypertension are not well established. The objective of this study is to investigate associations of diet and lifestyle factors, evaluated both individually and in combination, with prevalent hypertension among Korean adults. We analyzed data obtained from the 2007-2008 Korean National Health and Nutritional Examination Survey, a nationwide cross-sectional study using a stratified, multistage probability sampling design. The associations of 12 nutrient intakes and lifestyle factors with risk of hypertension were explored using restricted cubic spline regression and logistic regression models among 6,351 adults. Total energy and several nutrients and minerals, including, calcium, vitamin A, vitamin C, and sodium, showed non-linear relationships with the risk of prevalent hypertension. In multivariate logistic regression models, dietary score, obesity and alcohol intake were independently associated with the risk of prevalent hypertension, but smoking and physical activity were not. Overall, participants whose dietary habits and lifestyle factors were all in the low-risk group had 68% lower prevalence of hypertension (OR: 0.32, 95 CI: 0.14-0.74) compared to those who were at least one in the high-risk group of any dietary or lifestyle factors. The result suggests that combined optimal lifestyle habits are strongly associated with lower prevalence of hypertension among Korean adults.

  • This study used the characteristics of the knowledge discovery and data mining algorithms to develop tailored hypertension follow up management model - hypertension care predictive model and hypertension care compliance segmentation model - for hypertension management using the Korea National Health Insurance Corporation database(the insureds’ screening and health care benefit data). This study validated the predictive power of data mining algorithms by comparing the performance of logistic regression, decision tree, and ensemble technique. On the basis of internal and external validation, it was found that the model performance of logistic regression method was the best among the above three techniques on hypertension care predictive model and hypertension care compliance segmentation model was developed by Decision tree analysis. This study produced several factors affecting the outbreak of hypertension using screening. It is considered to be a contributing factor towards the nation’s building of a Hypertension follow up Management System in the near future by bringing forth representative results on the rise and care of hypertension.

  • We studied the incidence and results of treatment of secondary hypertension in Yeungnam University Hospital. Ntneteen hundred fifty patients with hypertension were included from march 1990 to march 1994. We analysed the prevalence of secondary hypertension and results of treatment. The incidence of secondary hypertension in Yeungnam University Hospital was six percent. The most common underlying causes of secondary hypertension was renal parenchymal disease. Patients with three forms of potentially reversible secondary hypertension, namely, renovascular hypertension, endocrine disease exogenous hormone, were assed to determine whether surgery or withdrawal of the exogenous hormone had led to an improvement in blood pressure control. The incidence of secondary hypertension in Yeungnam University Hospital was low(6%), but some of these are curable. Thus it is very inportant that evaluate the secondary hypertension.

  • The purpose of this study was to estimate the prevalence of hypertension, and to assess the risk factors associated with hypertension in elderly (over 65 years old) Koreans, using data from the 4th Korean National Health & Nutrition Examination Survey (the 4th KNHANES), 2007~2009. A total of 1,887 participants were analyzed for assessing the risk factors after excluding those who took hypertension medicines or underwent diet therapy (hypertension perceivers). On the other hand, in analyzing prevalence, a total of 3,526 people were analyzed, including hypertension perceivers. Hypertension was more frequently found in female (64.1%) and urban (62.0%) groups compared to male (55.6%) and rural (57.4%) groups. The mean age of the hypertensive group was significantly higher than that of normal group. The mean values of total cholesterol levels were also significantly higher in the hypertensive group, while body weight, waist circumference, fasting blood glucose, hemoglobin, hematocrit, LDL-cholesterol, and HDL-cholesterol were not. Multiple logistic regression showed that smoking was significantly related to the prevalence of hypertension, but alcohol drinking, stress, obesity, hypercholesterolemia, hypertriglyceridemia, diabetes, anemia, and nutrient intakes were not. The results of this study does not support clear relations of hypertension with chronic diseases including obesity, hyperlipidemia, anemia, and diabetes as well as nutrient intakes among a Korean elderly population. A prospective long-term research study is needed to establish the effects of these factors on hypertension.

  • The present study was aimed at investigating whether the calcium current in the vascular smooth muscle (VSM) cells is altered in renal hypertension. Two-kidney, one clip (2K1C) and deoxycorticosterone acetate (DOCA)-salt hypertension were made in Sprague-Dawley rats. Rats without clipping the renal artery or implanting DOCA were used as control for 2K1C and DOCA-salt hypertension, respectively. Four weeks after clipping, systolic blood pressure was significantly higher in 2K1C rats than in control $(192{\pm}24\;and\;119{\pm}4$ mmHg, respectively, n=16 each). DOCA-salt rats also showed a higher blood pressure $(180{\pm}15$ mmHg, n=18) compared with control $(121{\pm}6$ mmHg, n=14). VSM cells were enzymatically and mechanically isolated from basilar arteries. Single relaxed VSM cells measured $5{\sim}10\;{\mu}m$ in width and $70{\sim}150\;{\mu}m$ in length were obtained. VSM cells could not be differentiated in size and shape between hypertensive and normotensive rats under light microscopy. High-threshold (L-type) calcium currents were recorded using whole-cell patch clamp technique. The amplitude of the current recorded from VSM cells was larger in 2K1C hypertension than in control. Neither the voltage-dependence of the calcium current nor the cell capacitance was significantly affected by 2K1C hypertension. By contrast, the amplitude of the calcium current was not altered in DOCA-salt hypertension. These results suggest that high-threshold calcium current of the VSM cells is altered in 2K1C hypertension, and that calcium channel may not be involved in calcium recruitment of VSM in DOCA-salt hypertension.

  • The purpose of this study is to contribute basic data toward the efficient management of Hypertension by comprehensive analysis of several factors which make influences on indicators of Hypertension management. To achieve this, using the data of 2007, 2008 Korea National Health and Nutrition Examination Survey, 2,580 adults aged over 19 who suffered from hypertension have been analyzed comprehensively. The major results can be summarized as follows: First, in regard to the influential factors for awareness and treatment of hypertension, the older the patients were, the poorer their self-rated health status were. And when they had experienced a health examination, the more likely the hypertensive patients were aware of their hypertension and took the treatment for it. Second, as for the influential factors for control of hypertension, those who were older and those who had a health examination were significantly more likely to control their hypertension irrespective of gender. However, regular drinkers fell significantly behind in that aspect. The findings of this study show that systematic hypertension management, focusing on health behavior factors that affect the level of hypertension management, in accordance with the patients' sex and age will provide a more efficient way.

  • Objectives : To estimate the prevalence of hypertension, rates of awareness, treatment modalities, and control of hypertension, and also to identify factors in rural Korea that are related to these aspects of hypertension. Methods : A cross-sectional survey, including blood pressure(BP) measurements and interviews, investigating the variables in the health belief model was peformed from August to November, 1999 on 1,426 (79.4%) study subjects out of 1,797 registered residents over 30 years old in Ibansong-Myun, Chinju City. A second survey was peformed from January to March, 2000 on 376 (80.0%) subjects out of 470 hypertensive (or suspected hypertensive) subjects found in the first survey. Two BP readings were taken in each survey using a standard mercury sphygmomanometer. Hypertension was defined as either a BP reading $\geq$ 140/90 mmHg in both surveys, or as subjects on oral hypertensive medication. Results : Estimated hypertension prevalence was 24.9% for men, and 30.4% for women. Rates of hypertension awareness, treatment (the regular use of oral hypertensives), and control (reduction of BP to <140/90 mmHg) were 52.5%, 34.4%, and 12.9%, respectively. The factors related to lower hypertension awareness in the logistic regression analysis were male gender, farming occupation, and higher perceived barrier to medical treatment (those for whom visiting health professionals is a burden). Conclusions : To improve the low awareness, treatment, and control of hypertension, a more active and out-reaching hypertension control program, including routine BP measurements for every visitor to primary care facilities, is needed in rural Korea.

  • BACKGROUND/OBJECTIVES: This study examined the association between refined grain consumption by subtype and the incidence of hypertension from the Korean Genome and Epidemiology Study data. SUBJECTS/METHODS: In total, 5,018 participants (2,439 men and 2,579 women) from 40 to 69 years without hypertension were recruited at the beginning (2001-2002). Blood pressure and antihypertensive medication use were assessed biennially for the incidence of hypertension during the 8-year follow-up period (2009-2010). Hypertension was diagnosed as systolic blood pressure ${\geq}140mmHg$ or diastolic blood pressure ${\geq}90mmHg$ or antihypertensive medication use. Dietary intake including refined grains was assessed by a food frequency questionnaire at baseline and the follow-up (2005-2006). A multivariate Cox proportional hazard model was used to examine hazard ratios (HRs) and 95% confidence intervals (CIs) for incident hypertension according to refined-grain consumption. RESULTS: A total of 1,377 cases of hypertension (710 men and 667 women) were newly ascertained. Frequent noodle consumers (${\geq}5servings/week$) among the women had a 2.3-fold higher risk of hypertension than infrequent noodle consumers after adjustment for potential confounders (HR = 2.31, 95% CI = 1.33-4.01, P for trend = 0.0001). However, no significant association was found among the men. The intake of other refined grain products such as white rice and breads was not associated with the incidence of hypertension. CONCLUSION: Frequent noodle consumption was positively associated with a risk of incident hypertension in South Korean women.

  • Objectives: The purpose of the study is to investigate the health and oral health factors related to hypertension in Korean elderly. Methods: The study subjects were 1,527 elderly people${\geq}65$ years old who underwent physical examination and completed the health survey questionnaire of KNHANES 2014. Results: The risk of hypertension was higher in nonsmoking female elderly having poor subjective health status and low body mass index (BMI). The risk of hypertension was also higher in the elderly having poor subjective oral health status and no oral examination in the previous year. Conclusions: Health risk factors for hypertension and oral health factors may be useful measures to manage hypertension and enhance quality of life in the elderly.

  • This study investigated unmet health care needs and associated factors among patients with hypertension and those with diabetes. Patients were identified by medical professionals. Patients who did not take pharmaceuticals to treat their disease(s) were defined as those with unmet health care needs. Using data from 2005 National Health and Nutrition Examination Survey, 3,635 hypertension patients and 1,431 diabetes patients were analyzed. A multivariate logistic regression analysis was employed to examine factors associated with unmet needs. Overall, 16.6% of hypertension patients, 20.3% of those with diabetes presented unmet needs. Common factors associated unmet needs for both hypertension and diabetes were sex, insurance type, self-reported health status and length of disease. Study findings suggest that hypertension and diabetes should be treated in early stage and further study is needed to examine the reasons for unmet needs to improve patient's status effectively.
