Background Obesity is the prevalent disorder and is a serious public health concern because it is a significant forerunner of major chronic debilitating metabolic disease including diabetes, hypertension, lipid disorders and coronary artherosclerosis. Recently many studies shows that upper-body obesity, particulary increased visceral, abdominal fat, is most strongly associated with metaboloc risk factors. The aims of this study were to establish the relationship of body fat and its distribution to metaboloc risk factors and the clinical usefulness of waist circumference as a new indices of intraabdominal fat distribution. Methods Forty-one non-diabetic patients who visited to the health promotion center of Kosin Medical Center from March, 1998 to June, 1998 were divided into two groups according to the body mass index (BMI) : obese group (BMI≥25㎏/m^(2)) and non obese group (BMI<25㎏/m^(2)) also were divided into two group according to the waist circumference (W) : center obese group (W>94㎝ in men and W>80㎝ in women) and central non onese group (W≤94㎝ in men and W≤80㎝ in women). The amount of body fat was measured by bioelectrical impedence method. Insulin resistance was calculated by homeostasis model assessment. Results The result were as follows. 1) In obese group W and waist/hip ratio (WHP). basal insulin level in men and Smin, C-peptide and atherogenic index in women of obese group were higher than those of non-obese group (p<0.05). Insulin resistance, fat weight and lean body mass in the obese group were higher than those of non-obese group in both sexes (p<0.05). 2) In central obese group BMI, basal insulin level, insulin resistance, fat weight and lean body mass in men and atherogenic index in women were higher than those of central non-obese group. WHR in the central obese type group was higher than of central non-obese group in both sexes (p<0.05). 3) BMI was positively correlated with systolic blood pressure (r=0.32, p<0.05), diastolic blood pressure (r=0.36, p<0.05), insulin resistance (r=0.39, p<0.05), waist circumference (r=0.61, p<0.05), percentage of body fat (r=0.32, p<0.05), fat weight (r=0.61, p<0.01) and lean body mess (r=0.54, p<0.01), but negatively correlated with HDL-cholesterol (r=0.76, p<0.01). 4) Waist circumference was positively correlated with systolic blood pressure (r=0.46, p<0.01), diastolic blood pressure (r=0.37, p<0.05), fat weight (r=0.37, p<0.05), lean body mass (r=0.37, p<0.05), and WHR (r=0.82, p<0.01). 5) WHR was not significantly correlated with other metabolic risk factors except systolic blood pressure (r=0.39, p<0.05). 6) Fat weight was positively correlated with diastolic blood pressure (r=0.36, p<0.05), insulin resistance (r=0.53, p<0.01), basal insulin level (r=0.53, p<0.01),and percentage of body fat. Percentage of body fat was positively correlated with diastolic blood pressure (r=0.33, p<0.05), and insulin resistance (r=0.44, p<0.01). Conclusion Conclusively body fat, waist circumference and WHR were positively correlated with metabolic risk factors and waist circumference appeared more useful than WHR.

The Associations of Percent Body Fat with Dietary Intake, Plasma Lipids, Lipoprotein(a), and PAI-1 in Middle Aged Korean Adults

Kim Rim, Jean-Chinock,Kang, Soon-Ah,Hiojung Wee Korean Society of Community Nutrition 1998 대한지역사회영양학회지 Vol.3 No.5

This study was designed to investigate the associations of the percent body fat dietary intake, plasma lipoprotein profile, lipoprotein(a), and plasminogen activator inhibitor-1(PAI-1) concentrations of 1982 Korean subjects(men : 1000 and women : 982) between the ages of 40 and 59 years. The dietary assessment consisted of twenty-four hour dietary records and food frequency questionnaires. The subjects were identified into one of the five rating groups of % body fat : lean, underweight, normal, overweight and obese groups. The biochemical assessment included measurements of plasma total cholesterol(TC), HDL-cholesterol(HDL-C), LDL-cholesterol(LDL-C), triglyceride(TG), lipoprotein(a)(Lp(a)), and PAI-1. With respect to the ratio of percent energy intake of carbohydrate : protein : fat of the normal group of the women was 62% : 17% : 20%, respectively. Women apparently had a higher intake of carbohydrates than men(52% : 17 : 20%) did. There was a linear relationship between energy intake and % body fat in both mean and women(with the exception of the underweight group of women). The relationship of % body fat of men to the protein and fat intake was higher than that of the carbohydrate intake. Of the men in the study, intakes of energy, protein and alcohol were positively correlated to % body fat. In women, energy, carbohydrate and protein intake were positively correlated to % body fat, however, the fat, cholesterol and alcohol intake did not show any correlation to the % body fat in women. This study showed that % body fat was positively correlated with plasma TC, LDL-C, PAI-1 levels, and TG, but the % body fat was negatively correlated with plasma HDL-C level in both men and women. These results indicated that the high energy intake of obese or overweight subjects might contribute to several of the biochemical indices fo coronary heart disease(CHD) risk. In conclusion, increased energy intake is associated with overweight or obesity in middle aged Korean people. There was no relationship between % energy intake of fat and % body fat in the study, in middle-aged Korean men and women. The plasma lipid profile and PAI-1 level thought to be the risk factors of CHD were positively associated with percent body fat in middle aged Korean people.

고등학생의 신체활동량과 체력의 관계

구자천(Koo ja cheon),박문환(Park moom haun) 학습자중심교과교육학회 2010 학습자중심교과교육연구 Vol.10 No.2

본 연구는 고등학생들의 신체활동량과 체력을 측정하여 신체활동량과 체력의 관 련성을 파악하는데 그 목적을 두고 고등학생 73명(남:35명, 여학생:38)을 대상으로 비교․분석하여 얻은 결과는 다음과 같다. 체중, 체지방률, BMI, 체지방량, 체수분량에서 정상체중집단과 과체중집단간에 유의한 차이가 있는 것으로 나타났다. 신체활동량은 보행수(step)와 이동거리(mile) 에서 정상체중집단과 과체중집단간에 유의한 차이가 나타났으며, 성별에 따른 신체 활동량 비교 결과는 보행수(Tatal step), 칼로리소비량(Calories), 이동거리 (Distance), 지방소모량(Fat Burned)에서 집단간 유의한 차이가 있는 것으로 나타 났다. 신체활동량과 체력과의 상관관계 살펴보면, 남학생 경우 칼로리소비량 (Calories)과 지방소모량(Fat Burned)은 50m달리기, 제자리 멀리뛰기에서 정적상관 이 나타났으며, 여학생의 경우 보행수(Total step)와 이동거리(Distance)는 50m달리 기, 윗몸앉아굽히기, 오래달리기에서 정적상관이 나타났고, 칼로리소비량(Calories) 과 지방소모량(Fat Burned)은 윗몸앉아굽히기, 오래달리기에서 정적상관이 나타났 다. 신체활동량이 체력에 미치는 영향을 알아보기 위하여 다중회귀분석을 실시한 결과 남학생은 31%, 여학생은 45% 정도 영향력을 주는 것으로 나타났다. There is a significant difference in body composition(height, weight, BMI-Body Mass Index, muscle mass and impedance) based on the percentage of body fat each male and female student group. In the basic strength, normal group which is determined by the percentage of body fat shows higher numerical value than that of obesity group. Especially male students from the normal group get a high score in long-distance run-walking and female students from the normal group do in dangling with flexed arms. According to body mass index there is a significant difference in body composition- weight, percentage of body fat, muscle mass and impedance except heigh- each male and female student group. In the basic strength, normal group shows also higher numerical value than that of obesity group. Male students from the normal group get and female students from the normal group have a result that of percentage of body fat. Body composition according to the muscle mass shows a significant difference in both male and female student group. In male group all items have no significant difference in the basic strength. But female student group has a difference in dangling with flexed arms as shown in above percentage of body fat and BMI. The reason of similar result is from the high positive correlations. In the correlation of body composition and basic strength, male student group shows that body fat and body mass correlated with muscle endurance and cardiopulmonary endurance because percentage of body fat and BMI have a negative corelation in long-distance run-walking. On the other hand female group turns out that muscle endurance correlated with body fat, body mass and muscle mass because percentage of body fat, BMI and muscle mass have a negative correlation in dangling with flexed arms. There is the same result in the multiple regression analysis that is understanding of the relative importance from the effect of factors on basic strength and BMI.

Hydroxycitrate, Carnitine 및 Capsaicin을 함유한 식이 보조제(3D-Relax Diet)의 체중 감량 효과

정은영,정경희,김미자,배윤정,장은재 동덕여자대학교 2004 생활과학연구 Vol.9 No.-

The aim of this study was to evaluate the effects of 3D-Relax Diet; a proprietary formation containing hydroxycitrate(233mg/g), carnitine(150mg/g); and capsaicin (150mg/g); on body weight, % body fat, fat mass, lean body mass, Resting Metabolic Rate(RMR), body circumference, skinfold thickness, serum glucose and lipid level. Nineteen female college students participated in this 4 weeks weight control program. All subjects were randomly assigned to the Sang sik(S) group or Sang sik & 3D-Relax(3D) group. Mean energy intake of 3D group was l,523.1±300.2 ㎉(carbohydrate: 66.3%, protein: 18.7%, fat: 15.0%) and S group consumed 1,464.8±142.1 ㎉(carbohydrate: 65.1%, protein: 19.0%, fat: 15.9%) during program. The 3D group lost 3.1±1.3 kg of body weight, 2.5±l.4 kg of fat mass, 0.6±1.2 kg of lean body mass and 16.8±183.3 ㎉/d of RMR and the S group lost 1.8±1.0 kg of body weight, 1.1±1.1 kg of fat mass, 0.8±0.3 kg of lean body mass and 19.1±181.9 ㎉/d of RMR. There was no significant differences in the loss of lean body mass and RMR between two groups, however, the total body weight and the fat mass were significantly decreased in the 3D group compared to the S group(p<0.05). The 3D group experienced a significant reduced hip size, total-cholesterol and HDL-cholesterol, however, the change of these between groups were not significantly different. There were no differences in the change of body circumference, skinfold thickness, serum glucose and lipid. These results suggest that the intake of 3D-Relax Diet(hydroxycitrate, carnitine, and capsaicin) during the weight control program decreased energy intake, fat intake and total body weight especially fat mass and those effects are presumably linked to the prevention of RMR decline and the inhibitory effects on lipogenesis.

김선응(Seon Eung Kim),천인우(In Woo Cheon) 한국발육발달학회 2005 한국발육발달학회지 Vol.13 No.4

This study is investigate that body composition will be changed through the exercise program 160 subjects were divided into four groups such as control group, 4 weeks group, 8 weeks group and 16 weeks group. the % at, the amount of body fat and the weight of body fat were measured for the body composition. It showed that as for the effect of body composition, there was little difference in the % fat, the amount of body fat and the weight of body fat for the control group, and there was a little difference only in the rate of body fat for 4 weeks group, and there was difference in three items for 8 weeks group. It showed that there was difference in the % fat and the amount of body fat no difference in the weight of body fat. But it showed that body composition generally changed by application of the program.

A prospective study on changes in body composition and fat percentage during the first year of cancer treatment in children

Yang, Hye Ran,Choi, Hyoung Soo The Korean Nutrition Society 2019 Nutrition Research and Practice Vol.13 No.3

BACKGROUNDS/OBJECTIVES: Cancer treatment may lead to significant body composition changes and affect growth and disease outcomes in pediatric cancer patients. This prospective study aimed to evaluate short- and long-term body compositions changes focused on body fat during the first year of cancer treatment in children. SUBJECTS/METHODS: A prospective study was conducted in 30 pediatric cancer patients (19 hematologic malignancies and 11 solid tumors) and 30 age- and sex-matched healthy controls. Anthropometric measurements and body composition analysis using whole body dual energy X-ray absorptiometry were performed at baseline and 1, 6, and 12 month(s) of cancer treatment. Kruskal-Wallis tests, Wilcoxon paired t tests, and generalized estimation equation (GEE) were applied for statistical analysis. RESULTS: At baseline, no differences in weight, height, body mass index, abdominal circumferences, body fat, and fat-free mass were observed between 30 controls and 30 pediatric cancer patients. Total fat mass (P < 0.001) and body fat percentage (P = 0.002) increased significantly during the first month, but no changes were observed from 1 to 12 months; however, no changes in the total mass were observed during the first year of cancer treatment. Meanwhile, the total fat-free mass decreased during the first month (P = 0.008) and recovered between 6 and 12 months of follow-up (P < 0.001). According to GEE analysis, there was a significant upward trend in body fat percentage during the first year, especially the first month, of cancer treatment in children with hematologic malignancies, but not in those with solid tumors. CONCLUSIONS: Our results indicate that cancer treatment is related to significant body composition changes and rapid body fat gain, particularly during the first month after initiating cancer treatment, in children with hematologic malignancies. Therefore, individualized dietary strategies to prevent excessive fat gain are needed in pediatric cancer patients for better outcomes.

정상 체질량지수 여대생의 체지방률과 폐색성 동맥경화 위험요인과의 관계

백승희(Baek, Seung-Hui),최승욱(Choi, Seung-Wook) 한국체육과학회 2011 한국체육과학회지 Vol.20 No.5

This study was designed to analyze physique, body composition, blood pressure and risk factors of arteriosclerosis of 50 female students with normal BMI in D?S Women"s Universities, according to their body fat. As the result, the followings results were extracted. 1) physique and body composition, OG(Obesity Group) showed significantly higher WHR(Waist-Hip Ratio), % body fat & body fat mass than NG(Normal Group) at respectively, 5.6%, 34.0% and 43.7%(p<.001), but showed significantly lower lean mass(p<.01) 2) blood pressure, OG had higher SBP, MAP and DBP than NG at respectively, 3.9%, 4.8% and 5.6%, but there was no statistical difference between them. On the other hand, OG showed statistically higher Rb-aPWV and Lb-aPWV than NG at 6.4% and 7.0%(p<.01), when identifying risk factors of arteriosclerosis. 3) physique, body composition, blood pressure and risk factors of arteriosclerosis, then, there was a statistically significant, positive correlation with R. Lb-aPWV, as body fat percentage and body fat mass got higher(p<.05). However, they were in a negative correlation with lean mass(p<.05). These results demonstrate that high body fat has a cynical effect on blood pressure and risk factors of arteriosclerosis, even if female college students have normal BMI. Considering that female college students will perform important roles in taking care of health of their families as mothers in the future, it is extremely important to cut down on risks of their cardiovascular diseases. It is therefore, considered that a habitual exercise to reduce body fat is the most basic preventive activity to get rid of not only body fat, but also hazards of cardiovascular diseases.
