The purpose of this study was to investigate the relationship among nutritional status of copper and zinc, serum leptin, and lipids of 99 middle school girls residing in kyunggi-do, Korea. Subjects were divided assigned to one of two groups such as normal (BMI<85 percentile, n=58) and obese (85$\leq$BMI, n=41) groups. Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age was 13.93 years. The mean weight (p<0.001), BMI (p<0.001), body fat (p<0.001) of obese were significantly higher then those of normal group. The mean daily energy intake was 94.2% of RDA for Korean. The ratio of energy coming from carbohydrate, fat and protein was 63:24:13. The mean daily intakes of Cu and Zn were 1.4 mg and 7.4 mg (73.7% of RDA), and there were no significant difference between two groups. The mean serum levels of leptin (p<0.001), LDL-cholesterol (p<0.05), triglyceride (p<0.01), TPH (total cholesterol/HDL; p<0.001), LPH (LDL/HDL; p<0.001) and AI (atherogenic index; p<0.001) of obese were significantly higher than those of normal group. The mean serum Cu level of obese was significantly higher than normal group but, the mean serum Zn level of obese was significantly lower than normal group. Serum Cu showed a significantly positive correlations with body weight (p<0.001), BMI (p<0.001), body fat (p<0.001), serum leptin, and LPH. However, serum Zn showed a significantly negative correlations with body weight (p<0.001), BMI (p<0.001), serum leptin (p<0.001), TPH (p<0.05), and AI (Atherogenic index; p<0.05). To summarize the results, the Zn intakes of middle school girls did not reach to RDA for Koreans. Also, increase of BMI may lead to decrease of serum zinc level and increase of serum copper level, and this change of serum zinc related to the change of serum leptin and serum lipids level in middle school girls during rapid growth.

Chrominum (cr) plays an important role in carbohydrate and lipid metabolism , and Cr deficiency impairs glucose tolerance and increases serum cholestero and triglyceride. The relationship of serum Cr with serum blucose and lipids was examined in 79 female college students in Choong-Nam areas. Subjects were divided into underweight , normal , and overweight groups according to their BMI. The average age, wiegth , height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.6kg/$m^2$, respectively. Heights were not different between groups. Serum Cr and glucose concentrations werenot significantly different between groups. However, there was a tendency toward lowered serum Cr levels in under and over-weight groups. Serum cholesterol and LDL-cholesterol concentrations were significant lower in the underweight group than in other groups. BMI had positive correlation with LDL-cholesterol , AI and LPH , and negative corelations with HDL -cholesterol /total cholesterol ratio. Low serum Cr concentration was related to increased LDL-cholesterol and total cholesterol, and related to decreased HDL cholesterol in all groups . Therfore, serum Cr levels were lowered in abnormal weight groups and Cr may playan important role in coronrary heart diesease.

Purpose: 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. Method: 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. Result: 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. Conclusion: This study helps us recognize the importance of regular exercise and promotes motivation to exercise for a healthy life among middle-aged women.

This study was intended to figure out the interrelationship among body fat distribution serum insulin and lipids levels. One hundred forty four adult female from Chinju area were participated in this study. The survey was conducted between December 17, 1990-February 27, 1991, . The results are as follows : Wiast/hip girth ratio(WHR) and waist/thigh girth ratio(WTR) were increased with age and positively correlated with body mass index(BMI). It appeared that the prevalence of obesity in terms of BMI was higher in upper body type than intermediate or lower body type women. Correlation analyese indicated that serum triglyceride level seemed to be more closely associated with BMI and other body fat distribution indices. Analyses of the anthropometric data serum lipids and insulin were carried out by dividing the sample into three body type groups-upper body type women(WHR$\geq$0, .87) intermediate body type women(0.82$\leq$WHR$\leq$0.86) and low body type women(WHR$\leq$0.81) Age weight BMI RBW percentage of body fat serum insulin triglyceride cholesterol level of upper body type women were significnatly higher than that of intermediate or lower body type women(p<0.05) HDL-cholesterol was significantly lower in upper body type women. These results suggested that body fat distribution would be relevant to chronic metabolic diseases.

Purpose: The purpose of this study was to identify predictors of obesity, serum lipids and CRP in Korean adults. The predictors of obesity and serum lipids were the subject's general characteristics, life style, eating habit and nutrients. The predictors of CRP were the subject's general characteristics, life style, eating habit, nutrients, obesity and serum lipids. Method: 115 subjects who had visited the health examination center at a hospital participated in the study. The data analysed with descriptive analysis, ANOVA, Chi-square test, Pearson correlation coefficient and multiple regression. Result: Sex, married, eating out ($4{\leq}$/w), eating out (2-3/w) and age ($61{\leq}$) were anticipated variable on BMI ($R^2$=0.488). Sex and overeating (2-3/w) were anticipated variable on body fat($R^2$=0.218). Drink (4-6/w), age (51-60), sex, vegetable fat and Systolic BP were anticipated variable on total cholesterol ($R^2$=0.217). Age (51-60), vegetable fat and unmarried were anticipated variable on LDL ($R^2$=0.180). Sex was anticipated variable on HDL and Triglyceride ($R^2$=0.054, 0.192). Breakfast (1-3/w) and meal (2/d) were anticipated variable on CRP ($R^2$=0.1268). Conclusion: It is thought that decreasing eating out and overeating might be important to prevent obesity. It is thought that decreasing drinking and fat eating might be important to improve serum lipids. It is thought that eating breakfast might be important to decrease CRP.

The purpose of this study was to investigate the relationship among urn leptin, nutritional status, and urn lipids, glucose of 99 middle school girls residing in Kyluggi-do, Korea. Subjects were assigned to one of three groups such as underweight(BMI < 20, n=38), normal(20$\leq$BMI<25, n=36) and over weight(BMI$\geq$25, n=25) groups. The nutritional status of the subjects was evaluated by anthropometric measurements, questionnaires, 24-hr dietary recalls and blood anal),sis. The results were as follows : The mean age, body weight, height and BMI were 13.93 years, 55.19kg, 158.40cm and 21.96kg/㎡ respectively. The mean menarche age of the subjects was 12.64 years and the mean daily energy intake was 94.22% off RDA for Koreans. The energy ratio from carbohydrate fat and protein was 63: 24: 13. Underweight group showed the lowest intakes of oils and fats among three groups(p<0.05). The mean serum levels of leptin, glucose, total cholesterol, HDL-cholesterol. LDL-cholesterol and triglyceride were 10.57ng/ml 78.80mg/dl, 12.29mg/dl, 48.07mg/dl, 93.50mg/dl and 78.61mg/d1, respectively. The mean atherogenic index was 2.37. There were significant increases in serum leptin, glucose, LDL-cholesterol, triglyceride and atherogenic index of subjects with increases in their BMIs. Serum leptin showed a significantly positive correlation with BMI(p<0.001), body fat percent(p<0.001). When BMI was adjused, serum leptin showed a significantly positive partial correlations with intakes of animal protein(p<0.05), milks and animal foods(p<0.05), Serum leptin showed a significantly positive correlation with serum glucose(p<0.05) total cholesterol(p<0.01), LDL-cholesterol(p<0.001), triglyceride(p<0.001) and atherogenic index(p<0.001), however, it had significantly negative correlations with HDL-cholesterol(p<0.05). Therefore, these results suggest that the increase of serum levels of leptin may elevate the risk of cardiovascular disease and lipids and some nutrient intakes may be related with serum leptin levels.

This study was conducted to evaluate nutrient intake, indices of anemia, serum lipids, and their correlations in 40 Korean female college students aged 21 to 25 years. Fasting blood samples were collected in October. 1997 Nutrient intake was investigated by 24-hour recall method for three days. Anthropometric measurements, blood pressure, iron status and serum lipids of the subjects were determined. The mean values for age. height, weight, BMI and blood pressure of the subjects were 22.1 years, 160.6cm, 54.4kg and 109.1/66.9mmHg, respectively. According to the body composition analysis, total body water, % body fat, lean body mass and WHR were 26.7L. 29.5%, 36.5kg and 0.8, respectively. Average daily intake of energy was 1,858.4kcal. Protein, phosphorus, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than the Korean recommended dietary allowence(RDA), whereas calcium, iron, vitamin A intakes were tower than that. Hemoglobin(Hb), hematocrit(Hct), serum iron(SI) and total iron binding capacity(TIBC) were measured and transferrin saturation (TS%) was calculated from serum. The mean values for Hb, Hct, SI, TIBC and TS were 13.6$\mu\textrm{g}$/㎗, 41.6%,97.8$\mu\textrm{g}$/㎗, 319.6$\mu\textrm{g}$/㎗ and 31.9%, respectively. The Prevalence rates of iron deficiency assessed by Hb and Hct were found to be 10% and 2.5%, respectively. However, when assessed with TIBC, the prevalence rate of iron deficiency was increased to 32.5%. The mean values for serum triglyceride(TG), total cholesterol(TC), HDL-Chol, LDL-Chol concentrations and atherogenic index(AI) were 154.7mg/㎗, 80.0mg/㎗, 47.4mg/㎗, 91.3mg/㎗ and 2.6, respectively. Correlations among indices of anemia. there were positive correlations between Hb and Hct, between SI and TS : negative correlations between TIBC and TS or SI. Correlations among serum lipids, there were positive correlations between TC and TG or LDL-cholesterol. Energy intakes were correlated positively with TIBC(p＜0.05), and vitamin C intakes negatively correlated with Hb(P＜0.05). And vitamin A intakes were negatively correlated with TG(p＜0.01). TC(p＜0.05) and LDL-Chol(p＜0.01). Hb negatively correlated with TG(P＜0.05). Body weights(p＜0.05), lean body mass(p＜0.05) and total body water(p＜0.01) werenegatively correlated with Hb. BMI and WHR correlated with TG and TC(p＜0.01). These results indicated that subjects with higher energy intake and overweight had a tendency to have iron deficiency. Increases in BMI and WHR were related to increases in serum lipids levels and decreases in TIBC. The results also showed that serum lipids were decreased when vitamin A and iron intakes were sufficient.

Purpose: The purpose of this study is to find the effects of an exercise program on body composition, serum lipids, and menopausal symptoms in Korean menopausal women. Methods: This research used none qui valent control group pretest-posttest design. The participants were 30 middle-aged women who were divided into two groups, an experimental group (n = 16) who participated in the exercise program and a control group (n = 14). The exercise program was composed of gymnastic-ball exercises with RPE $12{\sim}13$ intensity, 50 minutes' duration and three times a week for 12 weeks from April 1 to June 30, 2008. The dependent variables (body composition, serum lipids, menopause symptoms, self-efficacy, and life satisfaction) were measured before and after exercise program. Results: There were statistically significant difference in weight (F=2.92, p=.049), percent body fat (F=4.22, p=.040), total cholesterol (F=2.63, p= .017) and high density lipoprotein (F=6.74, p= .015) between the two groups. Psychological menopausal symptoms also decreased significantly (F=7.01. p=.014) after the exercise in the experimental group. Conclusions: Regular gymnastic-ball exercises are helpful for menopausal women. They have positive effects not only on body composition and serum lipids but also on the decrease of menopausal symptoms. The results of this study suggest that gymnastic-ball exercise programs are effective in health promotion of Korean middle-aged women, and thus it is necessary to develop exercise programs for women.

The purpose of this study was to investigate daily nutrient intakes, serum minerals and lipids in university students majoring in physical education. Anthropometric measurement, dietary survey, and blood analysis were conducted and compared between physical education major (PM) and other major (OM) students. Average age was 21.3 years for PM students and 20.8 years for OM students. Body weight and BMI of PM students were significantly higher than those of OM students (p<0.05). Systolic blood pressure of PM students was significantly lower than that of OM students (p<0.05). Daily energy intake was 2,047.4 kcal for PM students and 2,393.9 kcal for OM students, indicating a significant difference. Carbohydrate and vitamin B1 intakes of PM students were significantly lower than those of OM students. Serum calcium was significantly higher in PM students while serum phosphorus and magnesium levels were higher in OM students. Serum total cholesterol and LDL-cholesterol were significantly lower in PM students while HDL-cholesterol was lower in OM students. In conclusion, university students who major in physical education showed higher serum calcium, lower serum phosphorus and magnesium, and lower systolic blood pressure and serum cholesterol levels than other major students. These results show that physical activity as a major course of study is associated with decreased blood pressure and blood lipids as well as altered serum mineral levels.
