Purpose: This study aimed to identify the differences in blood pressure among adults in the community according to age and time of the blood pressure measurement. Methods: This was a secondary analysis study, using data from a 2015 community health survey, conducted by the Korea Centers for Disease Control and Prevention. The data of three-time-measured blood pressure were collected from 337 subjects, 25, 35, 45, 55, 65, 75 years old, which are median ages by each age group. Results: The primary systolic pressure was significantly higher than the secondary systolic pressure (t= 3.46, p= .001) and the tertiary systolic pressure (t= 4.83, p= .001). The secondary systolic pressure was higher than the tertiary measurement (t= 2.05, p= .041). There was no significant difference between the three-time-measured values for diastolic pressure. There was a significant interaction between measurement times and age in the systoic blood pressure readings (F= 1.95, p= .036). However, there was no significant interaction between measurement times and age in the diastolic blood pressure readings (F= 1.03, p= .418). Conclusion: The findings suggest that attention must be paid to the use of blood pressure values in studies or one-time-measured clinical blood pressure values. In particular, the differences in systolic pressure readings taken at different times in the older age groups were significant. Therefore, it is more important to carefully assess blood pressure in adults over the age of 45 compared to other age groups.

Objective : To verify the separate and combined effects of cadmium and nickel on blood pressure in rats. Methods : Following the daily administration of cadmium chloride$(CdCl_2)$ and nickel chloride$(NiCl_2)$ to rats both individually and in combination with intraperitoneal injection method for one week, systolic blood pressure of the tail was measured at 1 day and 5, 10, 20, 30 days after administration. Each substance was injected into the rats with 0.1 mg/kg bw and 1.0 mg/kg bw concentration. Results : After 0.1 mg/kg bw $CdCl_2$ was injected, a statistically significant difference was found as compared with the control group(only saline) after 1, 5 and 10 days. After 0.1 mg/kg bw $NiCl_2$ was injected, a statistically significant difference was not found compared with the control group. After 0.1 mg/kg bw $CdCl_2$ and 0.1 mg/kg bw $NiCl_2$ were injected simultaneously, a statistically significant difference was found as compared with the control group after 1,5 and 10 days and compared with 0.1 mg/kg bw $CdCl_2$ group after 5 days and as compared with 0.1 mg/kg bw $NiCl_2$ group after 5 and 10 days. After 1.0 mg/kg bw $CdCl_2$ was injected, a statistically significant difference was found as compared with the control group after 1, 5, 10 and 20 days. After 1.0 mg/kg bw $NiCl_2$ was injected, a statistically significant difference was found as compared with the control group after 1 day and 5 days. After 1.0 mg/kg bw $CdCl_2$ and 1.0 mg/kg bw $NiCl_2$ were injected in combination, a statistically significant difference was found after 1, 5, 10, 20 and 30 days as compared with 1.0 mg/kg bw $CdCl_2$ after 10, 20 and 30 days and as compared with 1.0 mg/kg bw $NiCl_2$ after 5, 10, 20 and 30 days. Conclusion : It was found that the effect of $CdCl_2$ on blood pressure was much more than $NiCl_2$ and a high concentration $CdCl_2\;and\;NiCl_2$ in combination delayed the recovery of blood pressure.

Purpose : Pulse wave velocity(PWV) and ankle brachial index(ABI) are not only noninvasive methods used to assess arterial stiffness in adults, but also useful, simple ways to estimate the severity of hypertension, end stage renal disease and atherosclerosis in adults. But there are few studies on PWV and ABI in adolescents and children. In this study, hypertensive adolescents were compared to normal individuals to find out the usefulness of PWV as the index of progress in the disease. Methods : 413 teenagers were divided into three groups. The first group consisted of adolescents that only had hypertension(Group 1 : 23 teenagers). The second group consisted of the adolescents who had hypertension with obesity(Group 2 : 17 teenagers), and the last group was the normal subjects(Group 3 : 328 teenagers). Weight, height and body mass index were measured. Simultaneous measurements of systolic, diastolic and average blood pressure were obtained from the four extremities. PWV, ABI, ejection time and preejection period were also measured. Results : Right brachial-ankle PWV was significantly higher in both group 1 and group 2 compared with group 3, and significantly higher in group 2 compared with group 1. Likewise, left brachial-ankle PWV also showed significantly higher values in both group 1 and group 2 compared with group 3, and also higher values in group 2 compared with group 1. Positive correlations were found between the systolic, diastolic, average blood pressure and PWV. There were also positive correlations between the blood pressure and weight, body mass index. Conclusion : Higher PWV was demonstrated in adolescents with essential hypertension compared to normal subjects. Follow-up study is needed to evaluate the progress.

Purpose: This study aimed to study barley sprout powder's effect on blood lipids in women in their 50s. Methods: For 18 months of ingesting 3 grams of barley sprout powder daily, and the changes were investigated before and after the blood tests every six months. Results: The systolic blood pressure decreased from 107 mmHg for the first test to 91 for the fourth test. Diastolic blood pressure dropped from 69 mmHg to 49 mmHg at the first test. Abdominal circumference decreased from 84 cm at the first measurement to 78 cm at the fourth round. Fasting glucose and HDL were not affected. Total cholesterol was significantly refused from 264 mg/dl in the first measurement to 172 mg/dl in the fourth measurement. The first measurement of triglycerides in 2018 was 179 mg/dl, and it was highly reduced at the fourth measurements to 80 mg/dl. The first measurement of LDL was 182 mg/dl, and the fourth was a high decrease to 97 mg/ dl. Conclusions: After the women in the 50s ingesting sprout barley for 18 months, the overall improvements were shown by reducing significantly with fasting blood sugar, blood pressure, blood triglyceride, and LDL concentrations.

This study was performed to assess the risk factors associated with hypertension from Jan/2003 to Feb/2003. The subjects were 1,296 people (496 males, 800 females) aged 40 years and over living in Andong rural area. The hypertensive group was composed of 602 people (272 males, 330 females), who were diagnosed as hypertension ($SBP{\geq}140\;mmHg$ or $DBP{\geq}90\;mmHg$) for the first time at this health examination. The mean anthropometric values of body weight, body fat (%), body mass index (BMI) and waist circumference were significantly higher in hypertensive group than those in normal group. However, the biochemical measurements such as total-cholesterol (TC), triglyceride (TG), HDL-C, LDL-C and fasting blood glucose (FBG) levels did not show any difference between two groups except TG in female. The risk factors of interest in the development of hypertension were analyzed using the multiple logistic regression and expressed as odds ratio (OR) and 95% confidential interval (CI). The results showed that age, sex, obesity, waist circumference, alcohol drinking and meat intakes were risk factors for hypertension. In contrast, cigarette smoking, exercise and the increased fish, fruit and vegetable (except Kimchi) consumption, blood lipid levels and FBG were not linked with the development of hypertension. Nutrient intakes were not associated with hypertension, either. In conclusion, we cannot assert that this study established the existence of the cause-and-effect relationship between nutrient intakes and risk of hypertension in the subjects, but it does suggest that this is a question worth investigating further using a larger scale of case-control study to determine how the past exposure to some nutrient or dietary component relates to the development of the disease.

Objectives: The purpose of this study is to provide data for the improvement of hypertension management of community health practitioner posts through the study on hypertension management in community health practitioner posts. Methods: A questionnaire was mailed to 700 community health practitioners and 205 of them responded during the period from March 13, 2003 to May 13. The survey results were analyzed using SPSS program, version 11. Results: The results are as follows; 1. There are two major activities in a hypertension prevention project for community: health education and early detection. About 57% of community health care practitioners perform a health education for community people four times a year. The 64.5% of them used the materials for health education provided from a community health center and 22.1% of them performed a post-evaluation. The main method of early detection of hypertension was measurement of blood pressure of person to visit, which was 96.1%. Other methods included home visiting(89.3%), a referral from community hospitals and other resources(49.1%), health promotion events(39.5%), and a review of medical records(35.7%). 2. For the registration and management of patients with hypertension, about 36% of community health centers used a special form and more than 50% of them have registered patients who were managed by other health care institutions in the community. A computerized program was used for the management of patients with hypertension in 68.5% of them. More than 60% of them responded that it was used for report, treatment, and follow-up of patients with hypertension.

This study was proposed to investigate vital signs in subjects undergoing high magnetic field (3T) MR imaging for provide basic data on causes of claustrophobia as few previous studies were conducted on this special issue. Vital signs of 104 patients were monitored before and during the clinically indicated MR examinations to identify any relationship between MR scanning and the vital signs. An increase of systolic, diastolic blood pressure and pulse pressure were observed. However, they were not statistically significant(p>0.05), which meant the vital signs measured before and during the MRI scanning showed no significant change. This study is considered to be meaningful basic data for analyzing the links between vital sign fluctuations on claustrophobia during routine clinical MR examinations.
