The objective of this study was to investigate the relationship between changes in body temperature, adiposity and sympathoadrenal activity in normal weight female college students, eating an instant-noodle lunch in a laboratory setting at ambient temperatures of 22-24.8$^{\circ}C$. Preprandial epinephrine(EPI) concentration, as an indicator of adrenal activity, was inversely and significantly correlated with body weight, body mass index(BMI), and waist girth. Changes in pre- and postprandial EPI concentrations showed positive correlations with % body fat, fat mass, waist girth, hip girth, and waist/hip girth ratio(WHR). The preprandial norepinephrine (NE) concentration was negatively correlated with recovery time from the peak postprandial core temperature to the meal-start core temperature(RTST). However, the NE concentration, an indicator of sympathetic neural activity, was not related to anthropometric measurements in normal weight young women. In conclusion, adrenal activity was negatively associated with adiposity and central body fat distribution. Sympathetic activity was related to body temperature regulation capacity after a meal, but was not related to adiposity in normal weight young women. (Korean J Nutrition 31(7) 1130-1138, 1998)

Purpose: The purpose of this study was to investigate the effect of weight control program on body composition(body mass index and waist-hip ratio), blood pressure, serum lipids(total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein) and self-regulation behavior in obese college women. Methods: Forty seven obese subjects were divided into experimental(22) and control(25) groups. The weight control program lasting 12 weeks consisted of a traffic-light diet, jumping-rope exercises, and behavior modification methods with e-mail counseling. The data were collected from 29 March to 17 September of 2004. The variables were assessed before and after intervention for 12 weeks in two groups. Then, those were repeated after a 12 week suspension of intervention in the experimental group. The data were analysed by the SPSS computer program. Results: BMI, HDL, LDL and self-regulation behavior levels showed significant differences between the experimental and control groups. While there were no significant differences in waist-hip ratio, blood pressure, total cholesterol and triglyceride. Conclusion: The weight control program had a positive effect on obese college women, and can be used to control obesity.

We designed this study to compare the total body fat content and its distribution of diabetics with those of normal subjects. Skinfold thicknesses at eight sites(subscapular, subcostal, abdomen, suprailiac, triceps, forearm, thigh and calf) and body circumferences at five sites(waist, hip, arm, thigh and calf) were measured on 220 diabetics(82 male, 138 female) and on 160 nondiabetic subjects(male 57, female 103). We matched 92 pairs with diabetics and nondiabetic control subjects by sex, age, body weight and height, and made comparisons between two groups(case-control study). The results were as follows: 1) There was no significant difference in total body fat content of diabetics and control (male ; 20.40$\pm$2.12%, 19.20$\pm$3.52%, female ; 26.46$\pm$2.53%, 27.01$\pm$2.92%, respectively). However, body muscle mass(%) in diabetic men(33.37$\pm$4.19%) was significantly lower than in nondiabetic men(38.16$\pm$7.11%). 2) Diabetics, especially women, were characterized by more central body fat than control. That is, indices of centrality of body fat distribution(subscapular/triceps skinfold : STR, central/peripheral fat : CPR) of diabetics were higher than those of control. 3) Body weight, body mass index and %IBW(current body weight$\times$100/ideal body weight) had negative correlations with duration of diabetes(r=-0.23~-0.33), but total body fat content(%) and indices of body fat distribution, such as STR, CPR, waist/hip girth ratio(WHR), and waist/thigh girth ratio(WTR), were not related to duration of diabetes.

The purpose of this study was to investigate weight control practices and cardiovascular risk in middle-aged women. 304 middle-aged women were selected as subjects from thirties to fifthies living at J city in Chung-Buk Do. Data were collected using a questionnaire, anthropometric measurements, BP & total cholesterol level in serum from April 1, to June 30, 2003. The results of this study were as follows: The middle-aged woman's age is average $43.95{\pm}7.09yr$ and mean BMI(body mass index) was $23.54{\pm}3.09\;kg/m^2$. Underweight, normal weight, overweight, obese women were 3.0%, 39.5%, 27.9% and 29.6%respectively. Subjects perceived own as 'Slim' 5.9%, 'ordinary' 45.7%, 'Fat' 48.4%. Their weight perception coincide their own actual body weight but as many as 41.8% of overweight and 9.0% of obese perceived themselves as being 'ordinary'. Middle age women with past weight control experience were 55.6%, and only 35.5% was doing weight control at present. Of these subjects, 71.4% reported wanting to lose weight and the primary reason of weight control was to improve their appearance(39.53%). The most frequently reported weight control behavior was 'exercise' followed 'dieting', but 39.6% reported using 'diet food', 12.4% 'behavior modification', 12.4% 'fasting', and 'diet-drug'(3.6%) or 'smoking'(3.6%). Effective weight control methods were thought regular exercise(97.1%) & dieting (79.3%). And behavior modification(71.4%) or diet camp(60%) were effective, too. An average waist circumference was $79.80{\pm}9.47cm$, waist/hip ratio was $86.63{\pm}6.78$, waist/height ratio was $50.43{\pm}6.10$. In the index of abdominal obesity, 79.7 % of middle-aged women was waist/height ratio over 0.46, 65.3% was waist/hip ratio over 0.85, 28.4% was waist circumference over 85cm. There were significant differences in the degree of abdominal obesity according to age and BMI. In the index of cardiovascualr risk, 10.9% of middle aged women was systolic hypertension over 140mmHg, 18.7% was diastolic hypertension over 90mmHg and 10.6% was hypercholesterolemia over 200mg/dl. There was significant difference in systolic hypertension ratio according to age. There was significant difference in diastolic hypertension ratio according to age and obesity. There were significant differences in hypercholesterolemia accorting to obesity. The abdominal obesity indices and the levels of T-cholesterol in the serum, systolic and diastolic BP increased significantly according to age. T-cholesterol in serum was predicted 2.6% by waist/height ratio. And systolic BP was predicted 15.2% by waist/height, add BMI to 16.8%. Subject's diastolic BP was predicted 12.1% by BMI. Therefore waist/height ratio and BMI were significant factors for the predictors of cardiovascular risk. There was significant correlation between index of obesity and cardiovascular risk. T-cholesterol in serum had correlation with waist/eight ratio(r=0.174) and waist circumference(r=0.48). Systolic BP had correlation with waist/height ratio(r=0.387), and BMI(=0.371). diastolic BP correlation had correlation with BMI(r=0.343) and waist/height ratio(r=0.327). In conclusion, The prevalence of obesity was 29.6% in 304 cases, and increased as age after menopause increased. Middle-aged women's weight perception and actual BMI coincide but some of them did not. Trial to reduce weight was attempted. But most of them did not actually. Undesirable weight control method such as using drugs, fasting, smoking was used by some women. It is important to educate about health weight control methods and raise their awareness of exact body figures. High frequency of abdominal obesity in middle-aged women had correlation with hypertension and hypercholesterolemia. Abdominal index such as waist/height ratio, waist circumference, waist/hip ratio was used. Women's hypertension, hypercholesterolemia significantly related to body mass index and abdominal obesity.

This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.

The purpose of this study was to investigate the effects of 12 weeks of abdominal breathing exercises, through AB spur, on weight and BMI, % body fat, and waist-hip ratio in healthy college students. The subjects consisted of 20 obese young college students, and all of whom had no other health complications. The subjects were shown in detail the proper way to utilize the equipment and practice abdominal breathing in a laboratory setting. They were told to wear the AB spur for at least six hours a day in order to induce abdominal breathing exercise. Because the subjects were students, most of the abdominal breathing exercises took place while they were sitting in lectures at school, and they wore the equipment for 12 weeks. At 4, 8, and 12 weeks after the subjects started using the AB spur, there were significant decreases in weight, % body fat, BMI, and waist-hip ratio (p<0.05). In conclusion, the results of the stud suggest that abdominal breathing exercise may be a good weight loss method, as well as a beneficial way to decrease obesity factors, in obese college students.

This analysis was performed to investigate the relationship between nutrition and anthropometric indices using the data from a cross-sectional survey of a large national sample, '98 Korean national health and nutrition examination survey. Subjects were selected by stratified multistage probability sampling design and completed dietary questionnares including food intakes for one day by 24-hour recall method. For this analysis, 6566 subjects were selected by age(over 20 years old). For anthropometry, height, weight, and waist- and hip- circumference were measured. They were classified by body mass index(BMI, weight(Kg)/$height^2 $($m^2 $)) and waist-hip ratio(WHR, waist circumference(Cm)/hip circumference(Cm)). The nutrients intake of subjects were compared with the recommended daily allowances(RDA). Mean adequacy ratio(MAR) was calculated. Mean heights, weights, BMIs were higher in the groups with nutrient intake over 125% of RDA than the lower intake groups for most nutrients. However, Mean WHR was the highest in the groups with nutrient intake under 75% of RDA for most nutrients excluding iron intake of women aged 20-64 years. Among women aged 20-64 years, means of MAR were 0.71 for obese individuals(BMI>30), 0.72 for subjects with underweight(BMI<18.5), and 0.76 for subjects with normal weight(18.5$\leq$BMI<25). Normal subjects has statistically significantly higher MAR than those of other groups. However, among elderly people aged over 65 years, obese group had the highest MAR, 0.68. Women with abdominal obesity(WHR>0.9) had lower MAR, 0.71 than those with normal weight(MAR=0.76). From these results, obesity and abdominal obesity seems to be the results of malnutrition including both undernutrition and overnutrition rather than simple problem of excess energy intake. Obesity in elderly people needs to be handled differently from adults.

This study was conducted to investigate the effect of weight control by use of commercial formula diet and nutrition education on 36 obese women over a period of 6 months. During the study it motivated ways for women to control their weight and improve their health, thus analyzing variables that influence weight control. To help weight control, for the first 3 weeks, along with 1 regular mea, 2-3 liquid formula diets of 135㎉ per pack a day were provided within the 1,200-800㎉ range. For 6 months since then, all 3 meals were taken regularly and it was recommended that energy which is 500㎉ less than energy requirement be taken. To evaluate the effect of weight change by the weight control program, anthropometric measurements, biochemicl parameter, and food behavior are measured. The mean body mass index(BMI) was 30.1$\pm$3.8(25.0-43.6) and it was in the upper 5 percentile of the mean BMI of Korean women. The percent of body fat was significantly reduced from 29.1$\pm$2.4 to 26.4$\pm$2.3, showing that the weight control program induced not only a change in weight but also a change in body composition. The body circumference such as waist and hip circumference and skinfold thickness measurements of biceps, triceps, subscapular and surprailiac were reduced significantly, but the mean waist-to-hip ratio didn't change. Singnificantly improved food behavior score measured by the questionnaire indicated that the weight-contorl program induced the change of the food behavior, as well. Weight loss also induced biochemical parameters of the subject, thus total cholesterol, LDL-Cholesterol, and triglycerol which were in the high range of the normal values were reduced to 20.2%(p<0.01), 22.2%(p<0.01), 25.8%(p<0.01), repectively. HDL-cholesterol didn't change significantly, but the ratio of HDL to total cholesterol increased(p<0.01).

Objectives: The purpose of this study was to investigate the effects of modified fasting therapy on the changes of body compositions. Methods: We analyzed the medical records of 33 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University from January 1st, 2011 to December 30th, 2015. They went through reducing food intakes period (7 days), fasting period (14 days) and refeeding period (14 days). Body compositions (weight, body mass index, skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were reviewed at each state. And then the data was analyzed. Results: The body composition values (weight, body mass index [BMI], skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) decreased during the fasting therapy period, as a whole. The weight, BMI, percent body fat and visceral fat area decreased during the reducing food intakes period, the fasting period and the refeeding period. The skeletal muscle mass and basal metabolic rate significantly decreased during the reducing food intakes period and the fasting period, and insignificantly increased during the refeeding period. Conclusions: Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions.

Objectives : This study is to examine the influence of exorcise program to body shape and body composition of women. Exercise program is composed muscular resistance exercise and aerobic exorcise with 70min/time, 5day/week for 4weeks and designed for the reinforcement of muscular strength and the decease the decrease of obesity. Methods : The subjects of this study are 26 females who are from twenty until thirty-nine years old and are divided into two groups according to Obese Rate. normal weight group is 18 females under a BMI of 23 and overweight group is 8 females over a BMI of 23. we measured body compositon and body shape with body composition analyzer(inbody 3.0) measured body compositions are body weight, Lean body mass, base metabolic rate, body fat, %body fat, waist hip ratio, body mass index. measured 6body shade are upper arm circumference, chest circumference, waist circumference, hip circumference, thigh circumference. the measurements had been taken before exercise of each group, after 4 weeks, after 8 weeks, after 12 weeks. Body compositon and body shape of the measured data were analyzed by two-way repeated ANOVA followed by Dunnett's Post hoc test using SPSS. Differences were considered significant at p<0.05. Results and Conclusions : The weight was reduced at a significant level in overweight group after 4 weeks. Body fat percent was reduced at a significant level in normal group alter 4 weeks and overweight group after 8 weeks. Waist-hip ratio was reduced at a significant level in normal and overweight group after 4 weeks. Lean body mass and body metabolic rate were reduced but did not satisfy statistical significance. Circumference of all body parts showed an decrease after 12 weeks exercise program. Upper Arm, Chest, Waist, Hip Circumference were reduced at a significant level in overweight group after 4 weeks, but In normal group only Waist Circumference was reduced at a significant level after 4 weeks. Aerobic and Circuit weight training for 12 weeks reduced body weight and body fat percent, waist circumstance statistically significant without loss of lean body mass and body metabolic rate. Also these change was more effective in overweight group than in normal group.
