Purpose: With increasing prevalence of hypertension (HTN) in children and adolescent, pediatricians have become more interested in blood pressure (BP) measurements. The ambulatory blood pressure monitoring (ABPM) is known to be useful to differentiate true HTN and white coat HTN. The object of this study is to assess the clinical usefulness of ABPM in Korean children and adolescents. Methods: A retrospective review of 51 patients in Kyungpook National University Hospital from January 2002 to February 2010 was done. All patients were 6-18 years old and underwent ABPM. We calculated the mean value of ABP, BP load, nocturnal dip and compared the results with the patients' diagnosis and characteristics. Results: The mean age of the 51 patients was $17.8{\pm}1.8$ years and 19 children were obese. 37 patients (72.5%) were truly hypertensive and 1 patient was diagnosed as masked HTN and 7 children (14%) as white coat HTN. The rest of the patients were normotensive. Among patients with white coat HTN, 5 were in a prehypertensive state. Mean systolic and diastolic BP load of patients with true HTN were significantly higher than non-hypertensive children (P<0.001). Although the nocturnal dip of all patients were below 10%, there was no statistical significance. The obese patients showed higher systolic and diastolic BP. Their systolic and diastolic BP load were significantly higher than non-obese patients (P<0.001). Conclusion: ABPM in children and adolescents seems to be a valuable tool in the assessment of white coat HTN and in the confirmation of true HTN. A considerable number of white coat HTN patients are revealed to be in a prehypertensive state and need close follow-up.

Objectives: Anxiety and depression are known to be associated with hypertension, and blood pressure can vary spontaneously throughout the day. The aim of this study was to evaluate anxiety, depression and 24-hour ambulatory blood pressure (24-h ambulatory BP) in employees at their worksite. Methods: A total of 107 volunteers among 136 employees at a hotel in Gyeongju, Korea were enrolled in this study between December 2009 and March 2010. The Beck Anxiety Inventory (BAI) and the Beck Depression Inventory (BDI) were used to assess anxiety and depression, respectively. Blood pressure was measured using a 24-h ambulatory BP monitoring system. Results: No significant differences in either BAI or BDI scores were found when hypertensive individuals were compared to normotensive individuals. The frequency of diastolic non-dipper was significantly higher in individuals with depressive symptoms compared to those without (p<0.05). Depression was significantly associated with diastolic non-dipper (OR: 6.85, 95% CI: 1.50-30.01). Conclusions: The results of this study indicate that depression should be considered when deciding upon blood pressure control regimens, and appropriate additive psychotherapy may be beneficial in the treatment of hypertensive patients.

소금은 전통적인 조미료로서 동양인이 음식을 조리하는데 적지 않게 들어가 좋은 맛을 가져다 준다. 또한 소금중의 나트륨 역시 인체 생리 활동의 필수적인 요소이다. 이리하여 소금은 사람들의 일상 생활중 사용 범위는 지극히 넓으며 또한 매우 중요하다. 그러나 과다한 소금의 섭취 또한 인체 .건강에 유해하다. 많은 대규모의 유행 병학 연구에서 모두 식사내의 나트륨. 나트륨 칼륨의 비율과 혈압과는 명백한 관련이 있다는 것을 실증하였으며 높은 나트륨의 섭취는 고혈압의 위험 요소이며, 이 관점은 이미 대다수 학자의 공인을 받았다. 본문에서는 소금과 인체건강의 관계에 대해 간략히 서술하였다

$Na^{+}$는 체내에서 세포외액 (extracellular fluid)의 주요 양이온으로 세포내액과 세포외액은 세포막을 사이에 두고 $Na^{+}$와 $K^{+}$의 높은 농도의 차이를 유지하고 있다. 이러한 농도차이는 세포막에 있는 $Na^{+}$-K$^{+}$ATP ase의 활동에 의하여 유지되며 $Na^{+}$는 체액의 osmolarity와 혈장의 부피 유지, 신경흥분, 근육수축 및 영양소등의 이동에도 중요한 역할을 한다. 체내의 Na balance는 renin-aldosterone system에 의하여 신장에서의 배설조절로 이루어지며, 최근 Na대사에 관여하는 natriuretic hormone이 발견되고 있다. Na의 과잉섭취는 역학적 연구와 동물실험에서 고혈압의 유발인자로 제시되고 있으나, 임상적 연구에서는 Na제한이 혈압강하효과가 있다는 보고와 없다는 보고가 있어 결과가 뚜렷하지 않다. 이는 고혈압 환자중에는 salt-sensitive한 group자 salt-resistant group이 있다는 것과 산업화된 사회들의 Na 섭취량이 이미 너무 높은 수준으로 Na섭취증가와 혈압상승간의 관계를 현재의 연구 방법들로는 찾아내기 어렵다는 ‘saturation effect’로 설명한다. 그러나 Na섭취를 1일 70~100mEq.(NaCl 4.0~5.8g)이하로 줄이면 고혈압 발생이 현저히 감소하고 Na 섭취량이 1일 30mEq.(NaCl 1.7g)이하이면 고혈압은 거의 발생하지 않는다. 그러나 Na섭취가 1일 400mEq.(NaCl 23.2g)이상이 되더라도 인구 중 50~80%는 고혈압에 걸리지 않아 고혈압의 발생은 유전적 인자, 신장 기능의 부족에 의해 지배되고, Na이외에도 K, Ca등의 식이 인자 및 stress, 운동등의 환경적 요인들이 영향을 미친다. Na 섭취량은 자연식품에 들어있는 양 뿐 아니라, 가공과정, 조리가정, 식사 중에 첨가되는 양에 의하여 좌우되므로, Na 섭취량을 측정하기 매우 어렵다. 가장 널리 사용되는 방법은 24시간 소변 중 배설되는 Na의 양으로부터 추정하는 방법으로 우리나라의 경우, 이러한 방법으로 섭취량을 환산할 경우 1일 200~260mEq. (NaCl 11.6~15.1g) 정도이며 이중 80% 이상이 discretionary intake인 것으로 추정된다. 따라서 앞으로 Na섭취를 줄이도록 많은 노력을 기울여야 하겠다.

This study was attempted to observe leisure time physical activity pattern and its relationship to coronary risk factors (BMI, systolic blood pressure, diastolic blood pressure, serum total cholesterol, triglycerides, fasting blood sugar). Subjects participated in this study were 277 adult male workers of an industry in Kyungpook province, Korea. Energy expenditure were measured using modified Physical Activity History questionnaire of CARDIA study by interviewing. Serum total cholesterol, triglycerides and blood sugar level were tested with 5 ml fasting blood and height, weight and blood pressure were masured. Data on smoking and drinking habits and others were obtained. Geometric mean of leisure time physical energy expenditure were estimated as 212.80 kcal per week for study subjects and only 22.4% of them expended 2,000 kcal or more per week in leisure time physical activity. Taking walks or hikes and jogging or running were more frequent leisure time physical activities in study subjects. Statistically significant mean differences in total weekly leisure time physical activity for all coronary risk factors were not found among three groups. Because energy expenditure of leisure time was generally low in this subjects and most of them were healthy men, we did not found that leisure time physical activity was significantly associated with coronary risk factors.

Background: The existing data indicate that obstructive sleep apnea syndrome contributes to the development of cardiovascular dysfunction such as systemic hypertension and cardiac arrhythmias, and the cardiovascular dysfunction has a major effect on high long-term mortality rate in obstructive sleep apnea syndrome patients. To a large extent the various studies have helped to clarify the pathophysiology of obstructive sleep apnea, but many basic questions still remain unanswered. Methods: In this study, the influence of obstructive sleep apnea on systemic blood pressure, cardiac rhythm and urinary catecholamines concentration was evaluated. Over-night polysomnography, 24-hour ambulatory blood pressure and ECG monitoring, and measurement of urinary catecholamines, norepinephrine (UNE) and epinephrine (UEP), during waking and sleep were undertaken in obstructive sleep apnea syndrome patients group (OSAS, n=29) and control group (Control, n=25). Results: 1) In OSAS and Control, UNE and UEP concentrations during sleep were significantly lower than during waking (P<0.01). In UNE concentrations during sleep, OSAS showed higher levels compare to Control (P<0.05). 2) In OSAS, there was a increasing tendency of the number of non-dipper of nocturnal blood pressure compare to Control (P=0.089). 3) In both group (n=54), mean systolic blood pressure during waking and sleep showed significant correlation with polysomnographic data including apnea index (AI), apnea-hypopnea index (AHI), arterial oxygen saturation nadir ($SaO_2$ nadir) and degree of oxygen desaturation (DOD). And UNE concentrations during sleep were correlated with AI, AHI, $SaO_2$ nadir, DOD and mean diastolic blood pressure during sleep. 4) In OSAS with AI>20 (n==14), there was a significant difference of heart rates before, during and after apneic events (P<0.01), and these changes of heart rates were correlated with the duration of apnea (P<0.01). The difference of heart rates between apneic and postapneic period (${\Delta}HR$) was significantly correlated with the difference of arterial oxygen saturation between before and after apneic event (${\Delta}SaO_2$) (r=0.223, P<0.001). 5) There was no significant difference in the incidence of cardiac arrhythmias between OSAS and Control In Control, the incidence of ventricular ectopy during sleep was significantly lower than during waking. But in OSAS, there was no difference between during waking and sleep. Conclusion : These results suggested that recurrent hypoxia and arousals from sleep in patients with obstructive sleep apnea syndrome may increase sympathetic nervous system activity, and recurrent hypoxia and increased sympathetic nervous system activity could contribute to the development of cardiovascular dysfunction including the changes of systemic blood pressure and cardiac function.

This study was conducted to identify the factors of hypertension treatment in Gwangju and to establish a hypertension cure rate management plan by using local community health surveys to provide the hypertension cure rate management plan centering around the wellness local community. The research collected 13,714 Gwangju research data among a total of 685,820 local community health surveys of KDCA (Korea Disease Control and Prevention Agency) from 2017 to 2019. Among the data, 2,941 subjects, those with diagnosed hypertension aged over 30, were selected and analyzed through SAS 9.4, SAS Enterprise Miner 15.1. The results are as follows. The differences in hypertension diagnosis cure rate in Gwangju based on the subjects' socioeconomic characteristics were shown in gender, age, marital status, level of educational attainment, economic activity status, and monthly income. The significant differences in hypertension cure rate based on health behavior characteristics were shown in current smoking, monthly alcohol consumption, high-risk drinking, breakfast, recognition of good health level, diabetes and treatment, annual unmet medical needs, and annual health center use. As a result of the logistic regression analysis and interactive decision tree analysis to identify the factors affecting hypertension treatment, the research found that the factors that appear are age, marital status, diabetes and treatment, and annual unmet medical needs. Accordingly, to increase the recognition of the importance of hypertension treatment to people of young ages and not to develop complications, public health-educational effort in Gwangju is needed with an effective preparation plan.

This study was done to explore the level of physiologic health status and health promotion lifestyle, and its contributing factors of Korean older adults. A total of 209 older adults participated in this study that ran from July 2 to July 6, 2004 in the waiting area of the subways of Seoul. The average age of the respondents was 67 years old with 39.2% considering themselves as healthy, 71.3% stating they regularly exercised and 71.8% knowing their own blood pressure. Among the participants 44% were classified as having high or low blood pressure and 44.5% showing abnormal blood sugar. The mean score of health promotion lifestyle was 2.75 and the order of its subcategories was interpersonal relationship, nutrition, stress management, spiritual growth, physical activities, and health responsibilities. This score was altered by exercise and knowing personal blood pressure. As a result of this study, it is important for older adults to know their own blood pressure and to exercise regularly to promote good health. In addition, health promotion programs should be developed and implemented based on the influencing factors.
