To evaluate the ischemic heart disease risk factors and analysis on the its relationship between risk factors and ischemic heart disease on EKG findings in a rural area, We conducted cross-sectional health screening test for 1304 persons aged over 30 years. Blood pressure, total cholesterol, HDL cholesterol, fasting blood glucose, BMI and Waist/hip ratio, smoking data and EKG data were collected. Hypertension was classified by the sixth report of the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure and the cutpoints of hyperlipidemia was used National Cholesterol Education Program. The cutpoint of hyperglycemia was used National Diabetes Data Group and those for obese was 30%. The results obtained were as follows; 1. Prevalence of definitive hypertension was 41.2% in males and 41.6% in females. The prevalence of hypertension showed Increasing tendency according to age increase(p<0.05). 2. Prevalence of hyperlipidemia was 20.6% in males and 20.4% in female. In females prevalence of hyperlipidemia showed increasing tendency according to age increase(p<0.001). 3. Prevalence of obese was 23.4% in males and 28.8% in females. Upper body type was predominant in females, but lower body type was predominant in males. 4. Prevalence of hyperglycemia was 11.0% in males and 12.1% in females. The prevalence of hyperglycemia showed increasing tendency according to age increase(p<0.01). 5. The smoking rate was 63.7% in males and 2.6% in females. 6. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was 6.7% in males and 7.5% in females. 7. The prevalence of Ischemic heart disease was higher in hypertension than normal in females and higher in obese than normal in males. In males and females the prevalence of ischemic heart disease was higher in hyperglycemia than normal and higher in upper body type than lower body type. But there is no statistical association among them.

Purpose: Cardiovascular disease is one of the major causes of death not only in Korea but also worldwide. Atherogenic index of plasma (AIP) has been extensively investigated, but studies on nutritional intake and eating habits are scarce. The purpose of this study was to analyze the general characteristics, dietary habits, and nutritional status of Korean adults based on their AIP values using data from the 2013-2015 Korea National Health and Nutrition Examination Survey. Methods: A total number of 3,040 adults in their 20s and 30s were included as study subjects. They were divided into quintiles according to their AIP values. Comparisons were then made among the general information, eating habits, and nutritional intake statuses of the groups. Results: The averages of AIP were different by age, obese status, education, occupation, alcohol drinking frequency, smoking, and exercise in men. As for women, the averages of AIP were different by age, obese status, education, occupation, alcohol drinking frequency, and smoking status. Except for high-density lipoprotein (HDL)-cholesterol, higher AIP values in men were associated with significant increasing trends in health indicators, including systolic and diastolic blood pressure, fasting blood glucose, insulin, hemoglobin A1c, total cholesterol, triglyceride, and low-density lipoprotein (LDL)-cholesterol. As for women, as AIP increased, systolic and diastolic blood pressure, fasting blood glucose, insulin, total cholesterol, triglyceride, and LDL-cholesterol showed significant increasing trends except HDL-cholesterol. HDL-cholesterol showed a significant decreasing trend as AIP increased in men and women. In the high AIP group of women, the frequency of breakfast was lower, whereas the frequency of alcohol beverage consumption was higher. Conclusion: Among young adults, the risk of arteriosclerosis was higher in obese, smoking, and non-exercise individuals. More frequent alcohol drink consumption in women is associated with a higher risk of arteriosclerosis. Therefore, weight and lifestyle management are necessary for the prevention of atherosclerosis among young adults.

Purpose: This study examined the association between the antioxidant vitamin intake and obesity in Korean women. Methods: Adult women aged ${\geq}19years$ who completed a health examination and nutrition survey from the Korea National Health and Nutrition Examination Survey between 2007 ~ 2016 were selected for the study (n = 30,425). A BMI ${\geq}25kg/m^2$ and waist circumference ${\geq}85cm$ were defined as obesity and abdominal obesity, respectively. The individual antioxidant vitamin intake was estimated by linking the antioxidant vitamin composition database of commonly consumed foods and the subjects' 24-hour recall food consumption data. Carotenoids, retinol, vitamin A (retinol activity equivalent), vitamin C, tocopherols, and vitamin E (${\alpha}$-tocopherol equivalent) were included in the analysis. Each vitamin intake was converted to the nutrient density per 1,000 kcal. Odds ratio (ORs) and 95% confidence interval (CI) for obesity according to each tertile of the nutrient density was obtained from multiple logistic regression adjusted for age, household income, education level, smoking, alcohol consumption, and physical activity. Results: The mean intake of ${\alpha}$-carotene, retinol, vitamin E, ${\alpha}$-tocopherol, and ${\gamma}$-tocopherol per 1,000 kcal was significantly lower in the obese group than in the normal group. A higher intake of lycopene was inversely associated with obesity (highest vs. lowest; OR = 0.89, 95% CI: 0.83-0.96) and abdominal obesity (highest vs. lowest; OR = 0.88, 95% CI: 0.81-0.95). Higher intakes of ${\alpha}$-carotene, total carotenoids, vitamin A, and ${\gamma}$-tocopherol also had a negative relationship with abdominal obesity. The antioxidant vitamin intakes from eggs, milk and dairy products, seasoning, and grains were significantly lower in the obese group than in the normal group. Conclusion: This study showed that the dietary intake of antioxidant vitamins was inversely associated with obesity and abdominal obesity among Korean women. Further study will be needed to examine the causal relationship between the antioxidant vitamin and obesity.

This study focused on effects of patient exposure dose reduction with AEC (Auto Exposure Control) marker that is designed for showing location of AEC in X-ray Chest radiography. It included 880 adults who have to use Chest X-ray Digital Radiography system (DRS, LISTEM, Korea). AEC (Ion chambers are posited in top of both sides) are used to every adult and set X-ray system as Field size $17{\times}17inch$, 120kVp, FFD 180cm. 440 people of control group are posited on detector to include both sides of lung field and the other 440 people of experimental group are set to contact their lung directly to Ion chamber (making marker to shows location). Then, measured every DAP and, estimated patient effective dose by using PCXMC 2.0. The average age of control group (M:F=245:195) is 53.9 and the average BMI is 23.4. BMI ranges from under weight: 35, normal range: 279, over weight: 106 to obese: 20 and average DAP is 223.56mGycm2, Mean effective dose is 0.045mSv. The average age of experimental group (M:F=197:243) is 53.7 and the average BMI is 22.7. BMI ranges from under weight: 34, normal range: 315, over weight: 85 to obese: 6 and average DAP is 207.36mGycm2, Mean effective dose is 0.041mSv. Experimental group shows less Mean effective dose as 0.004mSv (9.7%) than control group. Also, patient numbers who got over exposure more than 0.056mSv (limit point to know efficiency of AEC marker) is 65 in control group (14.7%), 19 in experimental group (4.3%) and take statistics with t-Test. The statistical difference between two groups is 0.006. In order to use proper amount of X-ray in auto exposure controlled chest X-ray system, matching location between ion chamber and body part is needed, and using AEC marker (designed for showing location of ion chamber) is a way to reduce unnecessary patient exposure dose.

To investigate the total cholesterol level and its related factors in the rural and sea-board, 2,840 adults who participated voluntarily were examined during the study period December 1999 to February 2000. The height, weight, and fasting serum total cholesterol were measured. Body mass index was calculated. Information on age, gender, smoking, alcohol, and menopausal status in women were collected using a questionnaire by interviewing method. The mean value of total cholesterol was 191.6mg/ dl in sea- board and 173.6mg/ dl in rural men, respectively, and 206.9mg/ dl and 186.9mg/ dl in sea-board and in rural women. By simple analysis, in men, area, BMI and smoking were significant risk factors(p<0.01). Area(p<0.01), age(p<0.01), BMI(p<0.01), smoking(p<0.05), and menopausal status (p<0.01) were significant. In multiple linear regression analysis, the significant factors for total cholesterol in men were area(sea-board versus rural area; p<0.01), body mass index(the more obese; p<0.01), and smoking (non-smoker versus smoker ; p<0.05). Those in women were area(sea-board versus rural area; p<0.01), body mass index(the more obese; p<0.01), and menopausal status(menopause versus normal; p<0.01). Thus, in both gender, the significant factors related with total cholesterol were area and body mass index, and in addition to those, menopausal status was proved as a significant risk factor in women.

A study was performed to develop as a screening tool, the Simple Evaluation Questionnaire for screening Overweight Dietary Patterns in people in their 20's. We used the data from the 20 to 29 year old subjects who participated in the three surveys: the health behavior survey, the dietary habit survey and the food intake survey - as part of the National Health and Nutrition Survey of 1998. The 1,493 adults were classified into two body fatness groups, that of normal (including the underweight) , and the overweight (including the obese) on the basis of their relative body weight (RBW). When comparing general variables between the two groups, significant differences (11 variables) were found in gender, sadness/depression state, stress level, age, number of diseases, age when overweightedness started, maximum body weight, sleep length, presently a smoker, everyday smoking habits, number of alcoholic drinks in the past month, and the number of alcoholic drinks when dunk, as well as snacking frequency and fatty food consumption. There were significant differences between the two groups in the three variables of daily soup/kuk, pan fried fish/meat/poultry and cooked fish paste/ham/dried squid in terms of cooked food intake, and 11 variables of food size, cooked rice, stews, vegetables and kimchi at breakfast, panfried foods and beverage/teas at lunch, cooked rice and stews (liquid) at dinner, cooked fish paste/ham/dried squid at snacks and cooked fishpaste/ham/dried squid at snack between lunch and dinner. In terms of raw food intake, we observed significant differences (8 variables) in daily food intake and grains, grains/vegetables/fishes (shellfish) at breakfast, meat at lunch and milt at snack after dinner. After developing questions with indicators and analyzing the indicators by logistic regression analysis using 34 variables, including these 33, plus eating-out frequency, we chose 10 questions for the simple evaluation of dietary patterns for the overweight category, in order to give each one point each. Among them we assigned an additional point to one question and two points to another question. The average scores of the overweight and normal groups, as shown by the questionnaire developed, were 5.97 $\pm$ 2.36 and 7.36 $\pm$ 2.21, respectively. A score of seven points was selected as the cut-off point. We examined the sensitivity, specificity and positive predictive value of the questionnaire to the results of 49.3%,75.4% and 68.8%, respectively. The total score categorized as an overweight dietary pattern was 30.2%.

Leptin, the product of the obese gene, is produced by adipose tissue and is known to be a hormone concerned with regulation of appetite and metabolism. Recent reports have shown that leptin is associated not only with obesity but also with female reproduction, but it has not yet been ascertained whether leptin acts directly on the ovaries or indirectly via the hypothalamus or pituitary pathway. The object of this study is to determine the expression of leptin and its receptor in the ovaries of 3 and 8 weeks old rats by immunohistochemistry and RT-PCR. In the ovaries of 3 and 8 weeks old rats, leptin was stained in the theca cells and portions of granulosa cells of atretic follicles, whereas leptin receptors was stained in interstitial cells and ova of preantral follicles. The RT-PCR results showed that leptin receptor mRNA was expressed in the ovaries of both immature and adult rats, while leptin mRNA was not. In conclusion, leptin mRNA was not expressed in the ovaries, however, leptin was detected by immunohistochemistry. Compared to leptin itself, leptin receptors in the ovaries were ascertained by both RT-PCR and immunohistochemistry. These results suggest that leptin is related to the regulation of the physiological functions of the ovaries.

Objectives: The aim of this observational study was to identify and analyze the patterns to compare the characteristics of asthma patients. Methods: The subjects were 40 asthma patients who had satisfied the inclusion and exclusion criteria. They were divided into deficiency syndrome and excess syndrome groups, and cold syndrome and heat syndrome groups. Their quality of life was measured by the quality of life questionnaire for adult Korean asthmatics (QLQAKA) and VAS. Heart rate variability (HRV) was measured, and the degree of obesity was evaluated by body mass index (BMI). Hematological, biochemical, and immunoglobulin (Ig) E laboratory tests were included. Results: Based on pattern identification, the 40 asthma patients could be divided into two categories of groups: 1) the deficiency syndrome (N=18) and the excess syndrome (N=22) groups: 2) the cold syndrome (N=35) and the heat syndrome (N=5) groups. The mean value of HF differed significantly between the deficiency and excess syndrome groups. The mean value of IgE in blood tests of asthmatics was greater than four times the reference value. For BMI, the subjects were classified into three groups: normal weight (N=12), overweight (N=12), and obese (N=16). Conclusions: Development of a more accurate asthma-specific pattern identification tool could play a crucial role in asthma control. In addition, good control of asthma can improve the quality of life. Obesity is one of the factors associated with asthma exacerbation.

The study was performed for investigation with 257 female adults to find out the factors affecting health control behavior and obesity stress by personality type. First of all, BMIs of the respondents showed 30 low weight (11.7%), 170 normal weight (66.1%), 33 overweight (12.8%) and 24 obese respondents (9.4%). Comparing with low weight or normal weight, overweight or obesity could be seen as strong with diet control behaviors, from which obesity stress showed the tendency to be high accordingly. Second, the result of the investigation showed that for the open personality, which was featured as strongly desired to accomplish, very sincere and sensitive, they were more eager to control through health or diet. Third, the result of the investigation showed that for the more nervous, which is featured as emotionally unstable, bad at self control of impetus and clumsy to handle stress, the obesity stress was escalating.

Objectives: Exercise with partially restricted blood flow is a low-load, low-intensity resistance training regimen which may have the potential to increase muscle strength in the obese, elderly and frail who are unable to do high-load training. Restricted blood flow exercise has also been shown to affect blood vessel function variably and can, therefore, contribute to blood vessel dysfunction. This pilot study tests the hypothesis that unilateral resistance training of the leg extensors with partially restricted blood flow increases muscle strength and decreases vascular autoregulation. Methods: The subjects were nine normotensive, overweight, young adult African-Americans with low cardiorespiratory fitness who underwent unilateral training of the quadriceps' femoris muscles with partially restricted blood flow at 30% of the 1-repetition maximum (1-RM) load for 3 weeks. The 1-RM load and post-occlusion blood flow to the lower leg (calf) were measured during reactive hyperemia. Results: The 1-RM load increased in the trained legs from $77{\pm}3$ to $84{\pm}4 kg$ (P < 0.05) in the absence of a significant effect on the 1-RM load in the contralateral untrained legs (P > 0.1). Post-occlusion blood flow decreased significantly in the trained legs from $19{\pm}2$ to $13{\pm}2mL{\cdot}min^{-1}{\cdot}dL^{-1}$ (P < 0.05) and marginally in the contralateral untrained legs from $18{\pm}2$ to $16{\pm}1mL{\cdot}min^{-1}{\cdot}dL^{-1}$ (P = 0.09). Changes in post-occlusion blood flow to the skin overlying the trained and the contralateral untrained muscles were not significant. Conclusion: These results demonstrate that restricted blood flow exercise, which results in significant gains in muscle strength, may produce decrements in endothelial dysfunction and vascular autoregulation. Future studies should determine whether pharmacopuncture plays a role in treatments for such blood vessel dysfunction.
