Nuts are cholesterol free with high poly-unsaturated fatty acids(PUFA) and have lower intakes of sodium than non-consumers, and thus they can decrease blood pressure. Hypertension is a common primary diagnosis in Korea. Because of extending exposure to 24-hour raised blood pressure and heart rate hypertension is likely to be caused by prolonged short sleep durations. This study examined the relationship between nut consumption and hypertension according to sleep duration among Korean adult. Based on data from the 2010-2016 Korea National Health and Nutrition Examination Survey(KNHANES), the final analytic sample(n=25,359) was used for current analysis. The dietary intake was assessed through a 24-hour recall method. Associations of nut consumption with sleep duration and hypertension were determined using multiple logistic regression with odds ratio(95% CI). All the analyses were carried out in SAS version 9.4, and the significance level was set at p<0.05. With increasing nut intake, the prevalence of hypertension significantly decreased(p for trend=0.02). After controlling for sleep duration, the nut consumption showed significant association with the prevalence of hypertension when sleep duration was 6 to 6.9 h per day(p for trend=0.03) or 7 to 7.9 h per day(p for trend=0.03). In conclusion, dietary total nut intake was found to be significantly associated with the prevalence of hypertension.

Cognitive dysfunction is relatively less considered a complication of hypertension. However, there is sufficient evidence to show that high blood pressure in middle age increases the risk of cognitive decline and dementia in old age. The greatest impact on cognitive function in those with hypertension is on executive or frontal lobe function, similar to the area most damaged in vascular dementia. Possible cognitive disorders associated with hypertension are vascular dementia, Alzheimer disease, and Lewy body dementia, listed in decreasing strength of association. The pathophysiology of cognitive dysfunction in individuals with hypertension includes brain atrophy, microinfarcts, microbleeds, neuronal loss, white matter lesions, network disruption, neurovascular unit damage, reduced cerebral blood flow, blood-brain barrier damage, enlarged perivascular damage, and proteinopathy. Antihypertensive drugs may reduce the risk of cognitive decline and dementia. Given the high prevalence of dementia and its impact on quality of life, treatment of hypertension to reduce cognitive decline may be a clinically relevant intervention.

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.

Purpose: The purposes of this secondary analysis study was to examine prevalence, risk factors and unmet healthcare needs among adults with hypertension. Methods: A sample of 3,386 adults over the age of 40 with hypertension were drawn from the Korea Health Panel Study (2013). Using SPSS 22.0 version, descriptive statistics including frequency, percentage, chi-square and logistic regression were performed. Results: Results showed that 18.9% of the sample reported unmet healthcare needs with the most frequently cited one was financial burdens (43.2%). The reported experiences of unmet healthcare needs differed by gender, marital status, vision or hearing impairment, memory problem, impaired mobility, subjective health status, total family income, depressive episode and the difficulty in making decisions. The sample participants were more likely to report unmet healthcare if they had vision impairment, low income and perception that their health status as moderate to poor. Those without vision impairment were less likely to report unmet healthcare needs. Conclusion: The identified risk factors of unmet healthcare needs should be addressed which would enhance access both to health care and to resolution of unmet healthcare needs. Since visual ability seems to impact perception of unmet healthcare needs, it may be useful to find ways to address this factor.

Several studies revealed that low calcium intake is related to high prevalence of cardiovascular diseases such as hypertension. The prevalence of hypertension is high in Koreans along with their low dietary calcium consumption. Thus, the aim of this study was to evaluate the status of calcium intake between the hypertension and normotension groups and to investigate the correlation between dietary calcium intake and blood pressure, blood lipid parameters, and blood/urine oxidative stress indices. A total of 166 adult subjects participated in this study and were assigned to one of two study groups: a hypertension group (n = 83) who had 140 mmHg or higher in systolic blood pressure (SBP) or 90 mmHg or higher in diastolic blood pressure (DBP), and an age- and sex-matched normotension group (n = 83, 120 mmHg or less SBP and 80 mmHg or less DBP). The hypertension group consumed 360.5 mg calcium per day, which was lower than that of the normotension group (429.9 mg) but not showing significant difference. In the hypertension group, DBP had a significant negative correlation with plant calcium (P < 0.01) after adjusting for age, gender, body mass index (BMI), and energy intake. In the normotension group, total calcium and animal calcium intake were significantly and positively correlated with serum triglycerides. No significant relationship was found between calcium intake and blood/urine oxidative stress indices in both groups. Overall, these data suggest reconsideration of food sources for calcium consumption in management of the blood pressure or blood lipid profiles in both hypertensive and normotensive subjects.

The prevalence of postural hypotension among over 65 year old men is 10-30%. The postural hypotension commonly causes the discomfort such as dizziness, irritability or fainting spell, and for the result it diminishes the quality of the life of aged. Therefore the assessment and intervention of postural hypotension during changing position is very important. The purpose of this study is to investigate the effect of changing position from supine to standing upright, from supine through left lateral to standing upright, from supine through sitting to standing upright of aged. The results obtained are as follows : 1. The average systolic blood pressure of normotension group is $132.68{\pm}16.04mmHg$ at supine position. The average diastolic blood pressure of normotension group is $80.72{\pm}9.82mmHg$ at supine position. The average systolic blood pressure of hypertension group is $153.92{\pm}20.12mmHg$ at supine position. The average diastolic blood pressure of hypertension group is $93.74{\pm}15.53mmHg$ at supine position. 2. There is no significant difference of blood pressure after three different procedures as mentioned above from supine to standing upright. 3. The prevalence of postural hypotension at standing upright is 13.5% which is 18.8% of the hypertension group and 9.4% of the normotension group. There is statistical difference of the prevalence of postural hypotension between hypertension group and normotension group.

Objectives: Cardiovascular disease is one of the main causes of death and morbidity in Korea. In this study, the prevalence and incidence of developing hypertension in a male-workers' cohort were investigated during 3-years follow-up with a view to find the risk factors that affected the development of hypertension. Methods: Among the 5,374 people who participated in a routine health check up, 3,852 people with normal blood pressure and who had no history of hypertension were prospectively followed up for 3 years. The classification of hypertension was based on the JNC7 report (the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure). Life style factors and underlying diseases that were related to the risk factors of hypertension were collected by using a self-report questionnaires via the internet. Results: The prevalence of hypertension was 28.3% (1,520/5,374) at the first screening (2001). It was found that the incidence in 2004 of hypertension for the follow-up subjects (3,711) who had normal blood pressure in 2001 was 7.6 per 100 person-year. Multiple logistic regression analysis of the variables related to the risk factors of hypertension was carried out. The relative risks were 1.037 (95% CI=1.022-1.053) as the age increased 1 year and 1.039 (95% CI=1.023-1.055) as the body mass index increased $1kg/m^2$. The relative risk for the prehypertensive group was 2.501 (95% CI=1.986-3.149) compared to the normotensive group. These results showed that age, body mass index and the baseline blood pressure were significantly related to the incidence of hypertension. Conclusions: The incidence of hypertension was 7.6 per 100 person-year during follow-up. It was concluded that the risk factors for developing hypertension in the short-term were age, BMI, and prehypertension; Especially, this showed that it is necessary for prehypertensives to manage their body weight and blood pressure to prevent hypertension in middle-age by modifying their life style.

In order to investigate dietary risk factors for hypertension in th elderly, dietary intakes and dietary habits of 405 elderly subjects, aged 60-94, were assessed by the questionnaire, anthropometric measurement and a 24-hour dietary recall. The prevalence of definite (>95mmHg for diastolic or>160mmHg for systeolic blood pressue) and borderline(90-95mmHg for diastolic or 140-160mmHg for systolic blood pressure) hypertensive subjects 33.3% and 19.3%, respectively. The distribution of the subjects for Body Mass Index(BMI), waist-hip ratio, and alcohol consumption were significantly different among definite, borderline, and normal groups(p<0.05). The distribution of the subjects for smoking, exercise, and preference of salty food were not significantly different among definite, borderline, and normal groups(p>0.05). From the generalized logistic regression analysis of the risk factors for the hypertension, the subjects with over 27 of BMI had significantly higher risk of hypertension. Alcohol consumption and preference of salty food were significant risk factors of hypertension in the elderly. Dietary risk factors for the hypertension that had significant relationship to the hypertension were intakes of potassium, calcium, phosphate, sodium, vitamin B1, niacin, and folate. There was no significant difference of consumption frequencies of food and dish among definite, borderline, and normal groups(p>0.05). The amount of intakes for cereals and grain product, bean and their products, eggs were significantly different among definite, borderline, and normal groups(p<0.05). In summary, the amount of dietary intakes to hypertension in elderly population. Longitudinal studies for dietary risk factors on incidence of hypertension are needed in general population, especially in the elderly.

Dyslipidemia, hypertension, and diabetes are well-established risk factors for cardio-cerebrovascular disease (CVD). Although the prevalence of dyslipidemia among Korean adults is very high, its management is known to be poor. The aim of this study was to assess the prevalence, awareness, treatment, and control rates of dyslipidemia among adults aged 30 years and older in Gangwon-do, Korea. Analysis included 58,121 adults (29,123 males and 28,998 females) participating in the 2013-2014 Korea National Health Screening Program (KNHSP). Dyslipidemia was defined according to the treatment criteria rather than the diagnostic criteria in Korea. Therefore, high-low-density lipoprotein cholesterol (LDL)-cholesterolemia was deemed present in individuals with LDL-cholesterol levels that exceeded the appropriate risk-based threshold. The age-standardized prevalence was highest in dyslipidemia (32.5%), followed by hypertension (25.1%), and diabetes (9.4%). The awareness rate was 76.7% for hypertension and 74.7% for diabetes, but only 10.6% for dyslipidemia. The lowest patient treatment was found for dyslipidemia (9.4%). The control rate among those undergoing treatment was highest for hypertension (75.8), followed by dyslipidemia (63.3%), and diabetes (43.9%). The higher CVD-risk categories showed lower control rates of hyper-LDL-cholesterolemia. The prevalence of dyslipidemia was higher than hypertension and diabetes, but awareness and treatment rates were lower. Our findings indicate there is a wide gap between the prevalence of dyslipidemia and subsequent treatment, which suggests that effective strategies are required to improve dyslipidemia management. It would be worthwhile to strengthen the follow-up management of patients with dyslipidemia in the KNHSP, especially for the high risk group of CVD.
