A cross-sectional analysis of blood pressure (BP) changes and the current prevalence and distribution of hypertension among age groups in Korea were conducted. Systolic (SBP), diastolic (DBP), and pulse (PP) pressures were evaluated. Residents visiting a local Community Health Center for a health check-up and/or participating in the Health Promotion Program were included for the analyses. A total of 6,570 subjects (2,809 men, 3,761 women) were divided into five age groups: 30-39, 40-49, 50-59, 60-69, and $70\leq$ years. Comparisons were made between sex and among age groups. SBP and DBP were continuously elevated, while men showed higher levels than women until their mid-60s; then, the trend was reversed. DBP in men became elevated from their 30s, reaching the highest in the 40s then slowly decreasing. DBP in women increased up to their 40s and 50s, then reached a plateau. PP increased rapidly from the 50s in both sexes. The major contributor of age-related BP elevation may be large artery stiffness in men, particularly from their 50s, while the blood pressure elevation of women may relate to diverse factors including large artery stiffness, stroke volume, and ventricular ejection rate. The rapid elevation of PP after the 50s in both men and women could represent a risk of cardiovascular or coronary mortality, particularly with increasing age. The current data showed a higher rate of hypertension in both sexes compared to previous reports. When those with both high-normal BP and hypertension are looked at in combination, BP management of the target population should be drastically elevated.

The aim of this study was to find out the impact of age and hypertensive status on postprandial hypotension(PPH). Twenty-six hypertensive elderly ($77.7{\pm}7.2$ years old), twenty-five normotensive elderly ($80.2{\pm}6.8$ years old) and twenty-six young adults ($20.0{\pm}1.5$ years old) took part in the study. The blood pressure (BP) and heart rates (HR) were measured every 15 minutes, from 30 minutes before a meal to 90 minute after a meal in sitting position, using an ambulatory blood pressure monitor. In the hypertensive group, postprandial reduction in systolic BP continued from 30minutes to 90minutes. The reductuion rate of systolic BP of hypertensive elderly group was significantly greater than other groups (p<.05). However, there were no significant differences in trend of HR change between the groups (p=.082). The incidence of PPH was significantly higher in the hypertensives than other groups (73.1% vs 24% vs 0%, respectively, p=.001). In conclusion, age and hypertensive status had a significant impact on PPH. Elderly persons require more intensive BP monitoring and nursing intervention.

Purpose: The purpose of this study was to identify the prevalence, health behaviors, and control of hypertension in rural areas in Korea. Method: A total of 927 subjects above age 20 were selected from the areas which fell under the jurisdiction of the 24 Community Health Center located in Chungcheongbuk-do. The employees in the Community Health Center visited and interviewed patients. Data were collected using a questionnaire from July to October 2002. Result: The result showed that women had higher hypertension prevalence rates than men and the increment of its rate leveled up according to age. The hypertension prevalence rate was significantly high when the monthly income was less than 1 million won, their type of the Medical Insurance was the Guardian, they were only able to read Korean characters, and they were bereaved of spouses. In the Health behavior related to hypertension, the hypertension group showed a significantly lower level than the non- hypertension group in terms of drinking rate, smoking rate, intake of salt and intake of meat. There was no significant difference in the exercise rate and coffee intake rate between these groups. In the degree of the obesity the hypertension group was significantly higher than the non-hypertension group. The factors related to hypertension were that the duration for the incidence of hypertension was 12 to 60 months and took up 41.2%. The places where the medical check-ups occurred were the Community Health Center at 46.6%, the medical institution was mostly hospitals recording 46.5%. There were 66.1% of the targets who knew well about their blood pressure and there were 64.7% people who received education about it. As for the education place, the rate of Community Health Center was mostly high and it stood at 77.0%. In the aspect of the management of hypertension, the targets who took medicine on a regular basis were up to 76.1% and the targets who measured blood pressure once a month happened to be about 46.1 %. The targets who always recorded their blood pressure were 3.8%, chest X-ray as a related examination of hypertension reached 32.6%, electrocardiogram examination was 36.2%, cholesterol and serum lipid examination took up 33.6%, and the eye ground examination took 7.3%, which showed the lowest level of all.

The survey has for its object to detect prevalence rate of hypertension in target population, to find out the risk factor to hypertension, to detect the hypertensive patients cared pattern and therefore, to consider a effective counter plan for the long term about hypertension. The study, population of this survey was 894 out of 1013 target population from Feb. 1 1994 to March 31 1994 in Kyougsang-namdo Ulsan-gun Samnam-myoun. For these two month, check of blood pressure and direct measurement of height and weight was carried out by mass screening and home visiting and had an interview about risk factors for hypertension and cared pattern by questionnaire. The results of survey were as follows : 1. The prevalence rate of 894 study, population was 27.5% and 26.0% in man and 28.6% in women. 2. In male, the prevalence rate for age group, family history of hypertension, drinking, salt intake by risk factors were significant statistically. 3. In female, the prevalence rate for salt intake, body mass index by risk factors were significant statistically. 4. Motivation which was diagnosed as hypertension was that be examined for subjective symptoms of hypertension and routine check for health was only 25.0%, 9.1% and visiting to the hospital for other diseases, detect hypertension by chance was 65.9%. 5. The experience of treatment in prevalent cases was significant statistically in middle class of SES. And the place of treatment by risk factors could not be significant statistically in spite of the majority selected hospital generally. 6. The reasons of non-compliance in prevalent cases was restricting daily activities for its 45.5% most high and the interruption of treatment in prevalent cases was far from hospital geographically for its 47.6% most high 7. The preventive behavior about hypertensive by risk factors or general characteristics wasn't significant statistically. 8. Being treated or not in the near future about age group, SES, family history of the hypertension was significant statistically. And with regard to the place of treatment in the near future, in spite of the majority selected hospital generally, it wasn't significant statistically. 9. The reasons of non-compliance in incidence cases was restricting daily activities for its 46.8% most high. 10. The preventive behavior in the near future about age group, education level, SES, family history of hypertension was significant statistically.

Objectives: To estimate the prevalence rate of hypertension, the changes of health behavior, and compliance for the drug treatment after diagnosed as hypertension. Methods: 7,030 persons who live in Cheonan City of Chungnam Province were selected by the cluster sampling method, and 5,372 persons were surveyed by questionnaire and health examination. This data is analyzed by Chi-square test on each variable. Results: 49.8%- of men and 38.8%- of women had been diagnosed as hypertension, and the prevalence rate of hypertension was significantly increased with aging in both gender. The prevalence rate tended to decrease in highly educated women group. Unemployed persons or obese persons showed relatively higher prevalence rate. The prevalence rate of hypertension increased in groups with higher total cholesterol levels over 240 mg/dl, and groups with glucose level over 200 mg/dl. 53.1%- of male patients and 66.6%- of female patients showed compliance for antihypertensive treatment. Compliance for treatment was higher in aged group or lower educated group in both gender. Among men, proportion of compliant subjects was higher in unemployed group(49.3%-), and lower in labor or primary industry than the others but among women, there was not any significant difference. And men with compliance for treatment had higher monthly income than the others, but women did not show any. Conclusion : This population had a high prevalence rate of hypertension which may lead to cardiovascular disease. Therefore health education programs and distribution of information must be emphasized in order to increase compliance to treatment and encourage the change of health behavior to promote health.

Purpose: This study was performed to analyze the levels of blood pressure and to identify good or poor blood pressure control (BPC) groups among hypertension patients. The study was based on the Korea National Health and Nutrition Examination Survey (KNHANES VI and VII) conducted from 2013 to 2016. Methods: The sociodemographic and clinical data of 4,151 Korean hypertension patients aged 20-79 years and who were taking antihypertensive medications was extracted from the KNHANES VI and VII database. Descriptive statistics for complex samples and a decision-tree analysis were performed using the SPSS WIN 24.0 program. Results: The mean age was $62.46{\pm}0.21years$. The mean systolic blood pressure (SBP) was $128.07{\pm}0.28mmHg$, and the diastolic blood pressure (DBP) was $76.99{\pm}0.21mmHg$. 71.9% of participants showed normal blood pressure (SBP < 140mmHg and DBP < 90mmHg). From the decisiontrees analysis, the characteristics of participants related to good BPC group were presented with 9 different pathways same as those from the poor BPC group. Good or poor BPC groups were classified according to the patients' characteristics such as age, living status, occupation, education, hypertension diagnosis period, numbers of comorbidity, perceived health status, total cholesterol, high density lipoprotein-cholesterol, alcohol drinking per month, and depressive mood. Total cholesterol level (< 201mg/dL or ${\geq}201mg/dL$ cutoff point) was the most significant predictor of the participants' BPC group. Conclusion: This decision-tree model with the 18 different pathways can form a basis for the screening of hypertension patients with good or poor BPC in either clinical or community settings.

Metabolic syndrome (MetS), which is heavily dependent on dietary and lifestyle practices, is prevalent in Korean adults. Because dietary practices are unique for each race, nationality, and culture, it is important to identify Korean adult dietary practices that are associated with MetS. Macronutrient intake patterns were analyzed and compared across health status using the 2007-2008 Korean National Health and Nutrition Examination Survey data (8,143 adults who had dietary data and biomarkers related to MetS). Although intake levels were different by age, gender, and health status, carbohydrate intake was high and fat intake was low among Korean adults. The carbohydrate energy ratio was higher and the fat energy ratio was lower for subjects > 60 years old who were diagnosed with diabetes, hypertension, or MetS than those in other age groups. The main source of fat from food differed depending on the group. These results demonstrated that macronutrient intake patterns were different between age, gender, and health status subgroups. Hence, it is recommended that nutritional policy and practices aimed at controlling MetS should be based on the dietary characteristics of the target group.

To assess the effect of noise on the blood pressure of workers, 70 weaving and 70 refining female workers in 15 to 24 years of ages were tested for the changes of blood pressure before and after exposure to the noise. The noise levels at work place were 99 dB (A) for weavers and 80 dB(A) for refiners. The mean age of refiners was 17,7 years and that of weavers was 18.6 years, and the difference in mean ages was statistically significant (p<0.05). The means of heights, weights and working durations were not significantly different between two groups. The mean systolic blood pressure of the weavers was 112.5mmHg before exposure to the noise and it was increased to 115.7mmHg after exposure to 99 dB(A) of noise for 30 minutes, and the mean diastolic blood pressure from 71.6mmHg to 74.1mmHg. These increments of blood pressure were statististically significant (p<0.05). The mean systolic blood pressure of the refiners was decreased from 108.9mmHg to 106.7mmHg after exposure to 80 dB(A) of noise for 30 minutes, and the mean diastolic blood pressure from 67.3mmHg to 67.1mmHg. These changes of blood pressure were not statistically significant. The mean systolic and diastolic blood pressure of the weavers before exposure to the noise were significantly higher than that of refiners (p<0.05). The difference of blood pressure between refiners and weavers was significantly associated with noises (p<0.05), and not ages and their interactions. The study results support the hypothesis that exposure to excessive noise increases the blood pressure of workers.

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.
