The purpose of this study was to investigate whether group III muscle afferents play an important role eliciting abnormal blood pressure response mediated during passive muscle stretch in prehypertensive individuals. Eleven middle-aged prehypertensive men (average BP 133/80 mmHg) and nine middle-aged normotensive men (average BP 119/74 mmHg) participated in this study. After 1 min rest baseline data collection, the subject's foot was flexed (dorsiflexion) by an automated cybex for one minute. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), heart rate, stroke volume, cardiac output, and total peripheral resistance were continuously measured on a beat-by-beat basis from a finger via a Finapres device for 1 minute. To evaluate the role of mechanoreflex, a component of exercise pressor reflex, SBP, DBP, and MAP responses over the course of time were examined. The results showed that the pressor response mediated by the muscle mechanoreflex was faster in prehypertensive individuals compared to the normotensive individuals. The substantial pressor response was observed within mean 20 sec of the onset of passive stretch in prehypertension, while mean 45 sec in normotension (p<0.05). It is concluded that excessive pressor response produced during exercise in prehypertension may be due to the dysfunction of the mechano-receptors.

This study investigates the effects of wear training on blood pressure and blood lipid profiles. For the purpose of this research, 'wear training' refers to the alternating stimulation of temperature while using specific clothing under controlled situations ($18.8{\pm}0.2^{\circ}C$, $38{\pm}3%RH$). The participants alternated between two different garments producing a $1.5^{\circ}C$ difference in the innerest microclimate temperature over a period of 4 weeks. The experiments in this study were conducted in a comfortable environment after sufficient rest. The results were as follows. The systolic blood pressure and mean arterial pressure were lower in the post test than in the pre test (p<.05). The atherogenic index (AI) was also reduced and the LDL-C/HDL-C ratio increased (p<.05) in the post test. These results demonstrated that wear training positively affected improvement in vascular stiffness.

The purpose of this study is to investigate risk factors of pre-hypertension and hypertension in rural residents. Nine hundred and ninety four subjects aged 40-70 yrs in Chungnam-do participated in this study. The subjects (n = 824) were classified into three groups of hypertensive, pre-hypertensive, and normotensive according to the Joint National Committee (JNC)-7 criteria. The weight, body mass index (BMI), waist-hip ratio (WHR), and serum total protein, albumin, BUN, and triglyceride (TG) were positively correlated with SBP and DBP. After adjusted by age, sex and BMI, the total protein, albumin and TG were significantly correlated with SBP and DBP (p < 0.01). There was no significant difference in eating habits according to the level of blood pressure. The serum albumin, creatinine, Glu-FBS, Glu-PP l20, and triglyceride were higher in both prehypertensive and hypertensive group than in the normotensive group. However, mean serum cholesterol was not different among three blood pressure groups. In this study, the common risk factors of pre-hypertension and hyper-tension were male, age of fifties, lower education level, ex-smoking, higher drinking frequency, higher BMI, body fat %, waist circumference, WHR, serum albumin and diabetes, even though the degree of risks in these variables were higher in the hypertensive group. The higher BUN was a risk factor of prehypertension, while the family history, prediabetes, serum total protein, Glu-PP l20 and higher alcohol drinking amount were the risk factors of hypertension. This result suggests that maintaining good health habit and normal range of blood parameters as well as controlling body weight have to be paid attention in order to prevent hypertention, and further reseasch on the relationship of blood pressure and BUN are needed.

The purpose of this study was to examine the effects of acute aerobic exercise at different intensities on the blood pressure, blood lipids and fibrinolytic markers in pre-hypertension college-aged males. Six subjects performed an acute running exercise at three different intensities(low intensity(LI): 50-60% heart rate reserve(HRR), moderate intensity(MI): 60-70%HRR, and high intensity(HI): 70-80%HRR). The blood pressure(systolic(SBP) and diastolic blood pressure(DBP), blood lipids(total cholesterol(TC) and high-density lipoprotein cholesterol(HDL-C)) and fibrinolytic markers(tissue plasminogen activator(tPA) and plasminogen activator inhibitor-1(PAI-1)) were determined before(PRE), immediately after(POST) and 60minutes after the exercise(60 POST). Results: the SBP in the LI group was significantly increased at POST(p=0.013). The ES levels for the SBP in the MI and HI groups were reduced (-1.33 and -1.23, respectively), though the differences were not significant. The HDL in the MI(p=0.003) and HI(p=0.002) groups were significantly increased at 60 POST. Also, the tPA in the MI(p=0.021) and HI(p=0.042) groups were significantly increased at POST.

Objectives: The objective of this study was to identify the association of food intake with bio-physiological indicators: blood pressure, body mass index (BMI), waist/hip ratio (WHR), cholesterol and urine sugar among rural people. Methods: The subjects were 890 inhabitants from 14 towns of G County in Honam province. Data were collected by interview and self-reported with structured questionnaires from April 6th to 30th 2005. Data were analyzed with the frequency, percentage, t-test, $x^2$-test, ANOVA, Scheffe test and ANCOVA using SPSS 12.0 program. Results: Pre-hypertensive and hypertensive group was 27.0%, overweight and obese 27.1%, more than 0.90 in WHR 42.0%, more than 201 mg/dl of cholesterol 23.9%, and positive urine sugar was 8.7% in general. Among eleven food groups, fruit intakes were more effective in normotensive group than in the others. Vegetables, liquors, and milk products were 0.90 WHR more effective than the others. Milk products and liquors in BMI, and grains, beans and seaweed in low cholesterol group were more effective than the others. Conclusions: Bio-physiological indicators are related significantly only with fruits, milk products, meats, cereal and liquors among eleven food categories. Further study on the relationship between food intake, physical activities, smoking, drinking and lifestyle with bio-physiological indicators are suggested.

Objectives: DASH (dietary approaches to stop hypertension) diet are recommended as first-line therapy for prevention of hypertension individuals with high normal blood pressure. We studied the effects of DASH program on blood pressure among the pre-hypertension group. Methods: To determine the impact of dietary patterns on the control of hypertension we studied the subgroup of 141 participants with systolic blood pressure of 120 to 139 mm Hg or diastolic BP of 80 to 89mmHg, body mass index(BMI) ${\geq}25kg/m^3$ or waist to hip ratio(WHR) ${\geq}0.95$(for man). 0.85(for woman) enrolled in DASH program. Participants were received of education and consulting about DASH every week for 8 weeks. Results: The level of diet to prevention of hypertension and compliance of DASH increased after education. Also, The DASH program significantly reduced systolic BP (from $136.03{\pm}12.40mmHg$ to $126.09{\pm}11.25mmHg$, p< .01) and diastolic BP (from $81.80{\pm}6.32mmHg$ to $76.44{\pm}10.61mmHg$, p< .01). Conclusion: The DASH program effectively lowers BP and may be useful in achieving prevention of hypertension.

This study is to look at the risk of chronic diseases in adults and oral health behaviors affecting periodontitis by gender. This study selected 3,071 males aged 35 to 65, 4,273 females, and 7,344 people as the final subjects of the study using the sixth original data from the National Health and Nutrition Survey. In this study, subjective oral health classified under 'bad' presented 1.69 times(p<0.001) the risk of Periodontitis for males and 1.50 times(p<0.001) for females. There was a 2.01 times(p<0.001) of a risk of periodontitis for male and 1.40 times(p=0.001) of a risk for females. Smokers have a 1.68 times(p<0.001) of a risk for males and 2.07 times(p<0.001) of a risk for females, thus a higher risk for periodontitis for females. The risk of periodontitis was 1.44 times(p<0.001) of a risk for males and 1.30 times(p<0.05) for females when compared in normal hypertension. Obesity was at a rate of 1.199 times(p<0.05) as much for males in the non-military group, 1.202 times(p<0.05) that of females for periodontitis and putting females slightly more at risk. For diabetes, males were at risk of 1.28(p<0.05) whereas it being 1.53 times(p<0.05) for females, compared the average health female. In total, Males were found to be at the greatest risk of periodontitis, while women were at the highest risk for smoking. All parameters except smoking and diabetes show a higher risk of periodontitis for females. As males are more likely to have a higher risk of periodontitis than females, they are considered to be more interested in oral health care and need systematic oral health education and policies to prevent oral diseases.
