The purpose of this study is to evaluate the relationship of blood pressure with dietary habit and level of physical fitness of middle-aged male workers by age. The study subjects included 511 male employees who have worked at a company in C City, whose age was more than 40 years old. Between April 10 and May 30. 1998, all of the study subjects measured physical fitness (Balance, strength, power, agility, flexibility and endurance) and blood pressure. A questionnair was administered for dietary habit and socio-demographic characteristics. The average age (SD) of the study subjects was 46.61(3.98) years. The study subjects were classified by age into 3 groups; 40-44 aged group(34.6%), 45-49 aged group(41.3%), and 50-54 aged group (24.1%). The score of dietary habit of 40-44 aged group was $69.77{\pm}5.82$. that of 45-49 aged group was $69.77{\pm}5.83$, and that of 50-54 aged group was $71.85{\pm}6.82$(p=0.005). But age of health physical fitness tend to weaken in the age of 40-44. Systolic(p=.011) and Diastolic blood pressure (p= .011) were significantly increased with age increment. Diastolic blood pressure and dietary habit of 45-49 aged group showed the significant negative-correlation(r= .280. P<0.05). and Diastolic blood pressure and age of health physical fitness of 40-44 aged group showed the significant positive-correlation(r= .182. P<0.05). On the basis of the results of this study. I hope occupational nurses should play an active role to improve dietary habit and physical fitness for prevention of hypertension with increase of age in middle-aged male workers.

최근 만성질환자 건강관리의 목적으로 혈압측정에 대한 접근성을 높이는 제품 연구가 지속적으로 이루어지고 있다. 기존 연구에서는 심전도(ECG)와 광전용전맥파(PPG)를 분석하여 수축기혈압과 이완기 혈압을 산출하는 방식을 사용하고 있다. 주 과제는 정확도와 재현성을 위한 분석 알고리즘 개발이다. 본 연구에서는 초소형 혈압측정장치를 개발하는 단계에서 장치의 크기를 줄이고 측정방법도 간단히 하는 동시에 알고리즘도 두 개의 PPG만을 이용하여 최고혈압(SBP)을 추출하고 이에 따른 최저혈압(DBP)을 구하고자 하였다. 이를 위해 두 개의 PPG에서 얻은 측정값과 SBP, DBP 관계를 통계적으로 추적하여 상호관계를 분석하였다. PPG의 차이 값인 DF_P는 SBP와 반비례 관계가 있으며, DBP와는 비례적 관계가 성립되어 알고리즘에 의해 혈압값을 유추할 수 있으며, SBP를 통해 DBP를 추적할 수 있다.

High blood pressure (HTN) is a condition in which blood pressure is kept higher than normal. Blood pressure trait measures systolic blood pressure (SBP) which is the highest pressure and diastolic blood pressure (DBP) which is the lowest blood pressure. Pulse pressure (PP) is the difference between systolic and diastolic blood pressure. Hypertension is known as a disease caused by the interaction of the environment and genetic factors. To date, studies have been conducted to find genes associated with hypertension. Genome-Wide Association Study (GWAS) analysis using European data from the UK Biobank reported new 535 loci were associated with blood pressure trait. Among them, 12 genes have been reported to have a significant correlation with SBP, DBP and PP. In the study, 12 genes polymorphisms were extracted based on KARE (Korean association resource) and then we performed linear regression of blood pressure trait. As a result, 6 SNPs of the 3 genes (rs12355413 and rs11006736 of ARMC4, rs2290883, rs2290884 and rs11039014 of LRP4, rs7234941 of BCL2) showed statistically significant correlation (P<0.05) with blood pressure trait. Of the 3 genes, 6 SNPs in 2 genes (rs9651357, rs12355413, rs11006736, rs1889522 of ARMC4 and rs4987774, rs7234941 of BCL2) showed significant correlation with hypertension. These results suggest that genetic polymorphisms of ARMC4, LRP4 and BCL2 genes are associated with blood pressure traits and hypertension in Korean population. Moreover, we expected to help understand the pathogenesis of hypertension.

This research analyzed the hematological index and health related habits such as alcohol drinking, smoking and exercise, by classifying 539 middle-aged men (age: 40 - 59) into a normal weight group, an overweight group and an obese group, according to BMI (body mass index). As a result, 33.6% (n = 181) of subjects had a BMI of 23 or less and 30.2% (n = 163) were overweight and 36.2% (n = 195) were obese (BMI > 25). The average systolic/diastolic blood pressures of total subjects were 130.96mmHg and 80.38mmHg, respectively. And the average pressure of normal subjects was 126.85/77.57mmHg, which was significantly lower than in overweight and obese subjects. Diastolic blood pressure shows significant differences among the three groups. The overall average cholesterol level of normal subjects was 193.81mg/dl, which was significantly lower than those in overweight subjects. Those in obese subjects were significantly higher than in overweight subjects. The GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrutic transaminase), ${\gamma}$-GTP (gamma-glutamyl transpeptidase) levels of obese subjects were significantly higher than in the overweight subjects. Frequency of alcohol drinking showed no significant difference among the groups. The smoking ratio in the obese group was higher than in the normal and overweight groups. The ratio of smokers was 53.1 %, and the alcohol drinking ratio was 81.0% of the total subjects. The frequency of drinking showed significant correlations with systolic blood pressure (p < 0.05) and diastolic blood pressures (p < 0.01) and ${\gamma}$-GTP (p < 0.01). The duration of smoking showed a negative correlation (p < 0.01) with diastolic blood pressure, total cholesterol and ${\gamma}$-GTP. On the other hand, exercising frequency showed negative correlations with blood glucose, ${\gamma}$-GTP and GPT(p < 0.01). These hematological indices were correlated with health related habits such as alcohol drinking, smoking and lack of exercise, and to be the cause of chronic diseases. Therefore, proper nutritional education is needed to establish advisable health related habits to maintain proper body weight. (J Community Nutrition 8(2): 63-68, 2006)

Purpose : This study investigated the effect of bamboo stepping exercises on the blood pressure of the elderly. This study was performed for 8 weeks. Methods : The study participants included 25 people aged 65 and over. Of the participants, 16 were in the hypertensive elderly group and 9 were in the normal blood pressure elderly group. The participants stepped on semicircular bamboo for 20 minutes 3 times a week for 8 weeks. The participants' blood pressure was measured 3 times before and after 8 weeks of exercise. The mean values of the 3 before and after measurements were compared and analyzed statistically. Results : The systolic blood pressure of the hypertensive elderly group decreased significantly from $134.6{\pm}21.1mmHg$ to $119.9{\pm}18.1mmHg$ (p<.05). The diastolic blood pressure of the hypertensive elderly group decreased from $70.2{\pm}10.5mmHg$ to $66.1{\pm}9.8mmHg$, but the difference was not significant. The systolic blood pressure of the normal blood pressure elderly group decreased significantly from $127.2{\pm}18.7mmHg$ to $115.5{\pm}19mmHg$ (p<.05). The diastolic blood pressure of the normal blood pressure elderly group decreased from $72.6{\pm}11.3mmHg$ to $68.2{\pm}12mmHg$, but the decrease was not significant. Conclusion : After completing 8 weeks of the bamboo stepping exercises, the elderly participants' systolic blood pressure was effectively reduced. Today, lifestyle modifications, such as daily exercise, are necessary to control the blood pressure of the elderly. We hope that the bamboo stepping exercises, which are easy to perform and are not restricted by place and time, will become part of the elderly health policy.

In the automatic non-invasive blood pressure measurement device, the oscillometric method iswidely used. In the oscillometric method, the step-wise deflation has the advantage of the robustness for the motion artifacts than the linear deflation method. But it has the disadvantage of its longer measurement time because we need to detect two or more pulses in a certain cuff pressure step. In this study, we suggest the modified step-wise deflation method to overcome this limitation while maintaining the general concept of step-wise deflation. Using one valid pulse in each step and the deflating valve control during the diastolic period, the measurement time could be reduced. In order to verify the accuracy of the proposed algorithm, we compared the blood pressure values from the suggested method and the blood pressure values from the conventional auscultation method. The mean and standard deviation were -0.50${\pm}$5.3mmHg and 2.08${\pm}$4.75mmHg, for systolic and diastolic blood pressure respectively. The measurement time can be reduced up to the half of conventional step-wise deflation method.

Objective: The purpose of this study was to identify differences in measurement methods for blood pressure (Direct measurement, HP automatic indirect measurement, and SE 7000 Korean made indirect measurement), and to evaluate the clinical trial of the Korean made automatic indirect blood pressure measurement. Material & Methods: From June, 1999 to February, 2000, fifty five consecutive patients were randomized into hypertension group (n=20), normotension group (n=20), and hypotension group (n= 15). Measuring blood pressure by indirect methods (HP NIBP M 1008B and SE 7000 NIBP Korean made) was done simultaneously in the same arm with arterial line for direct blood pressure measurement (HP M1006A). The procedures were repeated ten times at intervals of 2 minutes. Statistical analysis was Performed using SPSS (version 8.0 for windows) software package. Values were expressed as means and standard deviation and means were compared using t-test. Statistical significance was considered present with a p value less than 0.05. Results: In the hypertension group and noromotension group, the disparity between HP direct measurement and indirect SE 7000 NIBP did not show any differences compared to the disparity between HP direct measurement and indirect HP NIBP. In the hypotension group, the disparity in the diastolic pressure between HP direct measurement and indirect SE 7000 NIBP was significantly different compared to the disparity between HP direct measurement and indirect HP NIBP (p<0.001), however, disparities in systolic pressure did not showed any differences. Conclusion: Direct blood pressure measurement (HP M1006A) can be replaced with indirect blood pressure measurements (HP NIBP M 1008B & SE 7000 NIBP) in normotension and hypertension patients. Korean made indirect measurement was found to be more accurate compared to HP indirect measurement in hypotension Patients, but more study is needed.

The effect of carbohydrates, fat and protein consumption on the blood pressure of adolescents was investigated from the cross sectional data. The two major areas of inquiry were : 1)measuring the variation of blood pressure at various levels of macronutient intake. 2)measuring the relative importance between the factor of nutrient intake and physical growth. A total of 726 students(341 boys and 385 girls) in the first grade of middle school in Kangwha country were studied for their dietary consumption and physical growth as well as blood pressure. Multiple regression analysis was used as the analytical method to identify the relative importance between the factors. Besides the macronutrient consumption, other nutrients such as vitamin and mineral intakes were included in the regression model. The results showed a variation of blood pressure by macronutrient intake level was in consistant both in blood pressure and by gender. Systolic and diastolic blood pressure decreased with increasing protein intake for girls(p<0.05). However, it was not observed in the case of boys. The systolic blood pressure of boys showed a tendency to decrease with fat intake increase, while their diastolic blood pressure showed the opposite trend. Results of the regression analysis showed that physical growth was a more influential factor than nutrition on blood pressure for both sexes. This could imply that the dietary hypertension factors observed in adults may not be operative generally in a population with normotensive blood pressure during growth.

This study was conducted to find out physical changes in the blood pressure and saliva cortisol of patients with high blood pressure and diabetes after participating in agro-healing activities. The saliva cortisol and blood pressure of 14 males and females aged 49.79±10.48 on average were measured after participating in agro-healing activities. The saliva collection system was used, and their satisfaction level for the program was also surveyed. Changes in the values before and after participating in the agro-healing activities were compared and analyzed. The cortisol concentration, a stress hormone, was reduced from 6.76nmol/L before the program to 4.86nmol/L after the program, down by 1.9nmol/L, which was a statistically significant difference (z=-3.170, p<.01). In addition, the cortisol concentration was gradually reduced through the entire program from Session 1 to Session 7. Changes in the blood pressure of subjects before and after participating in agro-healing activities were examined, and the total systolic and diastolic blood pressure continuously decreased after participating in agro-healing activities through the entire program from Session 1 to Session 7. Their systolic blood pressure was reduced statistically significantly (z=-1.947, p<.05). Also, participants' satisfaction was analyzed and it was found that more than 95% of participants answered 'satisfied' and 'very satisfied' with agro-healing activities. Therefore, these results indicate that agro-healing activities performed in the healing-farm had a positive impact on the cortisol concentration and blood pressure of patients with chronic diseases such as diabetes and high blood pressure. In addition, their high satisfaction for this program seemed to improve the psychological and physiological conditions of subjects.
