The purpose of this study was to investigate the waist to hip ratio, body fat, BMI(Body Mass Index), weight, serum lipids and to examine the correlation between waist to hip ratio, body fat, BMI(Body Mass Index), weight and serum lipids in obese college women. The subject were 52 college women with a score above 25 on the BMI, between March and May of 2000 at G Women's University. Data has been analyzed by SPSS/PC using frequency, percentage, mean, standard deviation, and Pearson Correlation Coefficient. The result of this study are as follows : 1. The mean of body weight and height of the subjects were 72.38kg, 160.23cm. 2. The mean of waist to hip ratio was 0.88, body fat was 38.88%, BMI(Body Mass Index) was 28.15, the level of total cholesterol was 174.88mg/dl, triglyceride was 104.29mg/dl, HDL-cholesterol was 50.83mg/dl, LDL-cholesterol was 104.23mg/dl. 3.Waist to hip ratio was more significantly correlated to triglyceride(r=.34, P<.05) and BMI(Body Mass Index) was more significantly correlated to triglyceride(r=.30, P<.05).
This study was done to compare the difference of obesity index(waist-hip ratio, body fat, body mass index, relative body weight), blood pressure and serum lipids in abdominal obesity and non abdominal in both men and women. Abdominal and non abdominal obesity was divided into waist-hip ratio above 0.85 in women and 0.95 in men. The subjects were 412 adults (age range 40-59), who had regular health examinations between 1996 to 1997 at the S-Hospital in Seoul. The data were analyzed using ANCOVA (for adjusted for age) and Pearson correlation coefficient. The results were as follows: 1. 39.9% of men and 42.5% of women had abdominal obesity. The average age group of abdominal obesity was 50.8 which is older than the non abdominal obesity group(48.0). 2. After they were adjusted for age, the group of men who have abdominal obesity had higher levels in body fat, body mass index, relative body weight, blood pressure, total cholesterol, LDL- cholesterol and triglyceride than the group of non abdominal obesity group. The group of women with abdominal obesity had higer levels in body fat, body mass index, relative body weight , blood pressure and triglyceride than the group of non abdominal obesity. 3. In the group of non abdominal obesity, the waist-hip ratio was significantly correlated to body fat, body mass index, relative body weight, blood pressure and serum lipids the group of abdominal obesity in men and women.
This study aims at examining the correlations between waist-hip ratio, body fat, BMI, relative body weight and serum lipids by men and women in 40's and 50's. The subjects were 412 adults, who had regular health examinations between January and December of 1996 at S-Hospital in Seoul. The data were analyzed using unpaired t-test and Pearson correlation coefficient. The results were as follows: 1. The group of men had higher levels in waist-hip ratio, BMI, body weight, triglyceride, total cholesterol / HDL-cholesterol ratio, LDL-cholesterol / HDL-cholesterol ratio than the group of women. The group of women had higher levels in body fat and HDL-cholesterol than the group of men. 2. In the group of men, waist-hip ratio more significantly correlated to serum lipids than body fat and BMI. In the group of women, body fat, BMI and relative body weight was more significantly correlated to serum lipids than waist-hip ratio.
The purpose of this study is to analyze the effects of exercise therapy on serum lipid levels and antioxidants of obese and normal college female students. The subject group composed of ten normal-weight students(below 30% body fat ratio) and ten obese students(above 30% body fat ratio). After a pilot test, the subjects were given an eight-weeks exercise program. Before and after the exercise program, the subjects were given test for serum lipid and antioxidants were analyzed. The SAS program was used in the data analysis. The statistical measurements employed here were T-test, Wilcoxon signed rank test, and Wilcoxon rank sum test. The results of this research are as follows. 1) The effects of exercise therapy on serum lipid levels; Before the exercise therapy, the levels of Total-cholesterol, Triglyceride and LDL-cholesterol of the obese group were higher than those of the normal-weight group. However, the HDL-cholesterol levels were higher in the normal-weight group than in the obese group, but these differences were not significant. With the exercise therapy, the levels of Total-cholesterol increased gradually. The HDL-cholesterol increased gradually, the LDL-cholesterol level decreased in both groups, However, the Triglyceride level decreased in the obese group and increased in normal group, but the difference was not significant. 2) The effects of the exercise therapy on serum antioxidants; Before exercise therapy, the serum FR and GSSG levels of the obese group were significantly higher than those if the normal-weight group(p=0.00, p=0.04). The serum GSH level of the normal-weight group was higher than that of the obese group, and the serum MDA level of the obese group was higher than that of the normal-weight group. Again these differences were not significant. With exercise therapy, serum FR level was reduced and serum GSSG level significantly increased in both group(obese group p=0.01, normal-weight group p=0.01), The serum GSH level of the obese group significantly increased(p=0.01), and serum MDA level significantly increase in the obese group(p=0.01), but the difference in the normal-weight group was not significant. These results show that regular exercise therapy reduces serum FR levels and activation of antioxidant systems, and suppress oxidative stress. These effects were slightly higher in the obese group than in the normal-weight group. The regular exercise therapy decrease the serum Triglyceride levels more in the obese group than in the normal-weight group. However the improvement of the serum lipid profile may require a longer exercise period than eight weeks. The results show that the exercise therapy was overall more effective in the obese group than the normal-weight group.
The purpose of this study was evaluate the usefulness of variables which were known to be related to blood pressure for discriminating between hypertensive and normotensive groups. Variables able such as smoking, alcohol, exercise, and stress, and demographic variables such as age, economical status, and education. The data were collected from 400 male clients who visited one university hospital located in Incheon, Republic of Korea, from May 1996 to December 1996 for a regular physical examination. Variables which showed significance for discriminating systolic blood pressure in this study were age, serum lipids, education, HDL, exercise, total smoking(in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-systolic pressure group was 2%, predicting a normal-systolic pressure group was 70.3%, and total Hit Ratio was 70%. Variables which showed significance for discriminating diastolic blood pressure were exercise, triglyceride, alcohol, smoking, economical status, age and BMI(in order of significance). By using the combination of these variables, the possibility of proper prediction for a high-diastolic pressure group was 71.2%, predicting a normal-diastolic pressure group was 71.3%, and total Hit Ratio was 71.3%. Multiple regression analysis was performed to examine the association of systolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the systolic blood pressure was statistically significant(p=.000) and adjusted R2 was 0.09. Adding the variable obesity on demographic variables resulted in raising adjusted R2 to 0.11(p=.000) ; therefore, the contribution rate of obesity on the systolic blood pressure was 2.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising adjusted R2 to 0.12(p=.000) : therefore, the contribution rate of serum lipid on the systolic pressure was 1.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted R2 to 0.18(p=.000) ; therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 6.0%. Multiple regression analysis was also performed to examine the association of diastolic blood pressure with life style-related variables after adjustment for obesity, serum lipids, and demographic variables. First, the effect of demographic variable alone on the diastolic blood pressure was statistically significant(p=.01) and adjusted R2 was 0.03. Adding the variable obesity on demographic variables resulted in raising adjusted R2 to 0.06(P=.000) ; therefore, the contribution rate of obesity on the diastolic blood pressure was 3.0%. On the next step, adding the variable serum lipids on the obesity and demographic variables resulted in raising the adjusted R2 to 0.09(p=.000) ; therefore, the contribution rate of serum lipid on the diastolic pressure was 3.0%. Finally, adding life style-related variables on all other variables resulted in raising the adjusted R2 to 0.12(p=.000) ; therefore, the contribution rate of life style-related variables on the systolic blood pressure after adjustment for obesity, serum lipids, and demographic variables was 3.0%.
This study was done to determine the effects of walking exercise training(WET) on metabolic syndrome risk factors and body composition in obese middle school girls.
A non-equivalent pretest-posttest experimental design was used. Twenty seven subjects participated in this study from one women's middle school in Busan. The participants were purposely allocated to an experimental group (n=14) and a control group (n=13). The experimental group participated in 30-60 minutes of WET with 55 to 75% of a maximal heart rate six days a week for 12 weeks.
The prevalence of individual risk factors on metabolic syndrome were improved in the experimental group after the intervention. The high waist circumference(WC), high triglyceride(TG), low high density lipoprotein cholesterol(HDL-C), high blood pressure(BP) and high fasting glucose(FG) were 21.4, 21.4, 14.3, 28.6 and 7.2%, respectively. There were significant differences in WC (F=22.24, p<.001), TG (F=5.34, p=0.30), body weight(F=21.99, p<.001), fat mass(F=19.17, p<.001), and % body fat(F=17.93, p<.001) between the experimental and control group after the intervention. However, there were no significant differences in HDL-C, FG and BP between the experimental and control group after the intervention.
These results indicate that WET is effective in decreasing risk factors of the metabolic syndrome and body composition components in obese middle school girls. These findings suggest that WET can be useful as a nursing intervention in the prevention of obesity-related disorders in obese adolescents.
This study was to examine the effect of an obesity management program on the body weight, body-mass index, and physiological index of obese female high school students.
Students from one school were selected as the experimental group, and students from another school as a control group so the latter group wasn't exposed to the experiment. The experimental group and the control group were each organized with 20 students. The experimental group received 60 minutes of behavior modification once a week, for eight weeks.
The Body weight, and Body mass-Index of the experimental group significantly decreased after the obesity management program. Total-cholesterol, T-G, and LDL-C significantly decreased and HDL-C increased in the experimental group. Total-cholesterol, T-G, LDL-C and HDL-C between the experimental group and control group showed significant differences.
These results indicate that the obesity management program had a great effect on decreasing the body weight and body-mass index of the female obese high school students, normalizing their physiological index. In conclusion, this program turned out to be one of the safest and most effective obesity-management methods that could be applied to female high school students.
This research was conducted to provide basic information about the effects of aerobic exercise on physiological change in middle-aged obese women according to differences of β3-adrenergic receptor polymorphisms.
Twenty-nine middle aged obese women with over 30%BMI were divided into three groups according to β3-adrenergic receptor gene polymorphism[Variable Group(VG):9, Normal Group(NG):10, Control Group(CG):10]. The VG and NG groups performed walking at 50% exercise intensity for 30 minutes a day, 4 days a week, for 12 weeks. The data was analyzed using the SPSS program.
The level of leptin, insulin and % body fat in the VG and NG groups was significantly lower than those of the CG after 12 weeks. In addition, the level of HDL-C in the VG and NG was significantly higher than that of the CG after 12 weeks. However, TC, TG and body weight between groups didn't appear significant at the end of 12 weeks.
Aerobic exercise didn't cause differences in persons with differing β3-adrenergic receptor gene polymorphisms, but aerobic exercise affected the physiological change in middle-aged obese women. The findings suggest that aerobic exercise is a desirable nursing intervention for obesity control in middle-aged obese women.
This study was performed to investigate effects of behavior modification on obesity index, skinfold thickness, body fat, serum lipids, serum leptin in obese elementary school children.
Forty seven students were selected from two elementary schools. Twenty four children in one school were assigned to experimental group and twenty three children in another school were assigned to control group. Experimental group was received 60~70 minutes of behavior modification once a week for 8 weeks.
Obesity index of the experimental group was significantly decreased after behavior modification. But there was no significant difference between two groups. The increase of skinfold thickness was significantly low in the experimental group compared to the control group. Percentage of body fat and fat mass were significantly decreased in the experimental group. Fat free mass was significantly increased in the experimental group. HDL-C, triglyceride and serum leptin between the experimental group and control group showed no significant difference.
These results indicate that behavior modification is effective in decreasing percentage of body fat and fat mass, in less increasing skinfold thickness and in increasing fat free mass. In conclusion, behavior modification can be used as effective strategy for managing obesity in elementary school children.
The purpose of this study was to confirm the effects of a moderate and fast walking exercise program on middle-aged women's fatigue, serum lipids and immunoglobulins.
A non-equivalent control group pretest-posttest design was used for this study. The experiment was conducted for 10 weeks from May 17th to July 25th, 2004 with 44 middle-aged women, consisting of 16 for the moderate walking group, 15 for the fast walking group and 13 for the control group.
Walking exercise at both a moderate and fast speed was effective in middle-aged women in reducing fatigue and serum lipids. It was also revealed that extended periods of exercise was more effective in decreasing fatigue while for reducing serum lipid, high intensity exercise was more effective. In this study, serum immunoglobulins were reduced after moderate and fast walking exercise but its cause was not fully understood so further research is needed.
This study helps us recognize the importance of regular exercise and promotes motivation to exercise for a healthy life among middle-aged women.
