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 was 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.

In the present study, the fluorescence behavior ova phenylethynyl-terminated imide (LaRC PETI-5) resin, a bismaleimide (BMI) resin, and various LaRC PETI-5/BMI blends with different blend compositions has been characterized as a function of heat-treatment temperature, using a steady-state fluorescence technique with a front-face illumination method far solid-state films. It is observed that there are distinguishable changes in the spectral shape, size, and position of fluorescence with varying heat-treatment temperature in the pure and blend samples. The result is qualitatively explained in terms of charge transfer complex formation as well as microenvironmental change with local mobility and viscosity occurring in the LaRC PETI-5, BMI, and their blends during the cure process. The result also implies that a steady-state fluorescence technique may be a useful tool to understand the processing conditions of polyimides and their blends in the film form on the basis of their thermo-photophysical responses.

Purpose : The purpose of this study is to ascertain whether age, body mass index(BMI) and exercise frequency(EF) are correlated with knee joint position sense in healthy women. Methods : Healthy women of 150 who participated in this study were tested knee joint position sense; each reposition error was analyzed according to the age, BMI and EF. Reposition error was measured with a Myrin goniometer. Results : The age groups, BMI groups and EF groups demonstrated significant differences of the knee joint position sense. The older the healthy women are, the higher BMI is, and the lower EF is, the more decreased knee joint position sense has become. Conclusion : The older the women are, the higher BMI is, and the lower EF is, the more decreased the knee joint position sense in healthy women is. Therefore it needs to be considered to require management of obesity and regular exercise for prevention of knee injuries due to decreased joint position sense.

목 적 : 소아 및 청소년 비만은 매년 증가되고 있는 추세이다. 소아와 청소년기라는 특성을 고려할 때 비만을 진단하는 기준 중, 어떤 기준을 적용하는 것이 비만아 선별검사에 좀더 유용한가에 대해 알아보고, 이렇게 선별된 비만아에서 비만과 관련된 여러 심혈관계 성인병 발생 위험 인자 중 조기에 예측 가능한 인자를 알아내어, 어떠한 인자가 추적관찰에 유용한지 알아보았다. 방 법 : 2001년 7월부터 11월까지 한국건강관리 협회와 인천광역시 교육청 주관으로 비만도 20% 이상인 중 고등학생 2,814명(남 : 녀=2,011 : 803)을 대상으로 하여 체중, 신장, 신체측정, 혈청지질(총 콜레스테롤, 혈청지질, HDL 콜레스테롤, LDL 콜레스테롤)을 측정하였다. 결 과 : 비만도 20% 이상인 중고생에서 BMI 95 백분위수 이상은 86.6%였으며, 체지방 기준에 의한 비만은 93.2%, 피하지방 두께에 의한 비만은 45.6%였다. BMI에 따른 비만아 중 고콜레스테롤혈증은 남아 21.0%, 여아 21.4%를 보였고, 비만도에 따라 나눈 남아 20.7%, 여아는 19.2%로 BMI와 큰 차이를 보이지 않았다. BMI에 따라 판정된 비만아를 세분하여 제 I도 과체중(고위험군, group I), 제 II도 과체중(비만, group II), 제 III도 과체중(과비만, group III)으로 나누어 보면, 남아에서는 고중성지방의 빈도가 group I에서는 15.0%, group II에서는 23.2%, group III은 34.5%로 비만할수록 더욱 증가하였고, 여아에서는 group I에서는 11.8%, group II는 20.7%, group III은 28.2%였다. 비만도에 의하면 남아에서 경도비만은 17.2%, 중증도 비만은 29.2%, 고도비만은 39.7%였고, 여아에서는 10.0%, 19.5%, 29.8%였다. 결 론 : 본 연구에서는 청소년기의 비만시 혈청지질 검사를 BMI만으로 하였을 경우 10.0-17.0%의 누락을 보였으므로 BMI 기준에 의한 혈중 지질의 측정은 한계가 있었다. 또한, 비만할수록 높아지는 고지혈증의 빈도는 비만도에 의한 것이 BMI보다 더 잘 반영하였다. 따라서 성인병 선별검사는 비만도에 의한 것이 좀더 누락율을 줄일 수 있을 것으로 사료된다. 심혈관 질환발생 위험 예측인자로는 남녀 모두 비만할수록 중성지방이 증가하여 중성지방이 관련 있는 것으로 나타났다.

목적: 아직까지 국내에서는 단지 비만 환자에 있어 수술 후 창상 합병증이 높을 것이라는 추측만 있을 뿐 정확히 체 질량 지수 값과 수술 후 창상 합병증과의 관계에 대해 조사된 바가 없다. 이에 대해 본원에서 위암으로 수술 받은 환자들을 대상으로 한국에서의 체 질량 지수 값과 수술 후 창상 합병증과의 관계에 대해 알아보고자 하였다. 대상 및 방법: 수술 후 창상 합병증은 2005년 9월부터 2006년 2월까지 서울아산병원에서 위암으로 수술 받은 772명의 환자들을 대상으로 하여 수술 전 과거력, 이학적 검사, 경과기록 등 의무 기록 등을 통해 후향적인 방법으로 조사하였다. 결과: 총 대상 환자는 772명이었으며 평균 나이는 $57.3{\pm}11.2$세였고, 성비는 남 : 여=1.82 : 1이었다. 수술 후 창상 합병증의 비율은 세 BMI 군간에 다르게 나타났다. BMI>$25\;kg/m^2$인 과 체중 환자 군에서 4.6%로, BMI<$20\;kg/m^2$인 저체중 환자 군과 $20M{\leq}BMI{\leq}25\;kg/m^2$인 정상 체중 환자 군의 0.9%, 1.6%보다 더 높게 나타났으며 통계학적으로 유의한 차이가 있었다(P=0.038). 결론: 과체중인 환자(BMI>$25\;kg/m^2$)는 저 체중 및 정상 체중인 환자($BMI{\leq}25\;kg/m^2$) 보다 수술 후 창상 합병증의 비율은 높았고 이는 BMI와 수술 후 창상 합병증은 유의하게 관계가 있는 것을 알 수 있었다.

This study was performed to examine the relationship between the body mass index (BMI), the body fat, and the serum lipids of post-menopausal women in rural areas. The subjects were 510 women aged 50 and over. As a result of this study, we found a trend of decreasing BMI as age increased, but body fat increased. In addition, there was a significant decreasing of the lean body mass than an increasing of the body mass index according to increasing age. Therefore, this study confirmed that a main cause of rural women being classified as obese is a decrease in lean body mass, rather than an increase in of body fat. Of all subjects, 36.3% ($18.5{\leq}BMI$ < 23) of all subjects were classified as having normal BMI, whereas only 21.4% were classified as having normal body fat. Out of 190 subjects who were body fat 30% and over, 38 subjects were classified as obese ($BMI{\geq}25$) and 113 subjects were classified as overweight ($23{\leq}BMI$ < 25). The percentile of those with a BMI of $25kg/m^2$ was 70, and they had 30.82% body fat. HDL cholesterol showed a negative correlation with anthropometric factors (height, weight, body mass index, waist circumference, waist hip ratio, body fat), and total cholesterol, LDL cholesterol, and triglycerides showed a positive correlation. Especially, total cholesterol, LDL cholesterol, and hip circumference showed significant correlations. Because of differences in the body fat and lean body mass by age group, it seems difficult to assess obesity via BMI only. The elderly especially should have a higher significance placed on body fat or abdominal fat than only BMI.

Supposing that somatotype evaluation results would have significant differences between the public group with less amounts of exercises and the special group with intensive exercises for three to four times a day, this study aimed at comparing the mutual consistency between the results determined by somatotype evaluation tools such as visually calculated index(VCI), R$\ddot{o}$hrer's Index(RI) and Body Mass Index(BMI). The public, taekwondo players and judo players groups were composed of fifty persons, taekwondo players and judo players passed through VCI determination, respectively. Their height and weight were examined and analyzed with somatotype evaluation tools. Comparison of somatotype dispersion of RI and VCI showed that most women were determined by VCI as lean type but were determined by RI as normal type. And that women were determined by VCI as fat type but were determined by RI as normal type. Therefore both men and women showed significant differences in VCI and RI. Comparison of somatotype dispersion of VCI and BMI showed that both men and women were overestimated or underestimated by VCI rather than by BMI. Comparison of somatotype dispersion of RI and BMI showed that men were less determined by BMI as lean type compared with women; both men and women less determined by BMI rather than by RI as normal type; and both men and women, in particular, were more determined by BMI as fat type but men were more determined by BMI rather than by RI as fat type. Total somatotype consistency by tools showed that VCI has the greatest possibility of determining the public group, compared with other groups as lean type and that the consistency of the three tools were relatively higher for the taekwondo players and judo players groups, compared with the public.

Purpose: Obesity is an important risk factor for hypertension in adolescents. We investigated the relationship of obesity-related indices (body mass index [BMI], waist-to-height ratio [WHR], and body fat percentage [%BF]) with blood pressure and the hemodynamic determinants of blood pressure in Korean adolescents. Methods: In 2008, 565 adolescents, aged 12-16 years, were examined. The %BF of the participants was measured by bioelectrical impedance analysis. Echocardiography and brachial artery pulse tracing were used to estimate the stroke volume (SV), cardiac output (CO), total vascular resistance (TVR), and total arterial compliance (TAC). Results: We noted that BMI, WHR, and %BF were positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP). The positive correlation between BMI and blood pressure (SBP and DBP) persisted after adjustment for WHR and %BF. However, after adjustment for BMI, the positive associations between blood pressure (SBP and DBP) and WHR as well as %BF, were not noted. With regard to the hemodynamic factors, BMI, but not WHR and %BF, was an independent positive factor correlated with SV and CO. TVR had an independent negative association with BMI; however, it was not associated with WHR or %BF. Moreover, we noted that BMI, WHR, and %BF did not affect TAC. Conclusion: In Korean adolescents, BMI had an independent positive correlation with SBP and DBP, possibly because of its effects on SV, CO, and TVR. WHR and %BF are believed to indirectly affect SBP and DBP through changes in BMI.

Reducing women's bone mineral density (BMD) has close relationship to risk in osteoporosis. This study was carried out to identify bone density risk factors affecting women's BMD, and to analyze the relationship of age, between BMD and menopause, BMI, blood pressure lifestyle and dietary habits for bone health by physical measurement and questionnaires. The study subjects, 128 women living in Seoul, were divided into 4 age group; 30~39 years (17), 40~49 years (54) and 50~59 years (36) and 60~69 years (21). There were significant differences in mean height, BMI, systolic blood pressure, menache and menopause age and menopause ratio and BMD T-score among the 4 age groups. BHD was significantly decreased according to increasing age and BMI and menopause. The rate of BMD risk subjects was significantly different increasing with age and BMI. The rate of risk group were 0%, 13%, 22.2% and 71.4%, by age groups and 0%, 16.2%, 33.3% and 52.9% by BMI respectively. BMD of menopause groups was significantly decreased from 1.23 (40 years) to 1.34 (60 years). p < 0.001. Also systolic blood pressure were significantly increased from 116.5 mmHg (30 years) to 130.81 mmHg (60 years). The T-score of normal group also decreased significantly from 1.27 to 0.13 (60years) with age. There were significant negative correlation between BMD and age (r = -0.409) menopause (r = -0.346), BMI (r = -0.218) systolic blood pressure (r = -0.193), salty taste eating out (r = -0.185) (p < 0.05). There were significant positive correlation between BMD and meat fish and walking time. In conclusion, bone density decreased with age. Most of the 50 years' subjects were in risk group. BMI, menopause, systolic blood pressure, frequency alcohol consuming. To prevent osteoporosis, over 40 years needed to be educated to maintain normal weight and the improvement of eating and living habits.

The purpose of this study was to determine the probability of overweight throughout childhood in relation to the presence of overweight at birch or in early childhood, and presence of overweight in children's parents. Weight and height measures were collected at birth and at ages of 7, 10, 12 years from 655 6th grade primary schoolchildren. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex, and overweight in children's parents as a body mass index at or above 27. The prevalence of overweight increased with age of the children. Overweight at birth was not associated with overweight at 12 years of ages. However, overweight at 12 years old was already related to overweight at 7 years old. In comparison to non-overweight peers, overweight children at ages 7(OR = 7.64, 95% CI = 4.32-13.51) and 10 years(OR = 19.69, 95% CI = 11.42-33.94) had a higher rick of becoming overweight at 12 years of age. Among children who was overweight at age 7years, 60.7% remained overweight 5 years later, Yearly increment in BMI of overweight children was larger than that of non-obese children (1.15-1.65kg/m$^2$vs 0.50-0.71kg/m$^2$. As compared with the lower case in mealy increment of BMI, the probability of being overweight at age of 12 years was greater in higher case. BMI values at age 7years were positively correlated with BMI values at age of 10 and 127ear,i, and with annual increments in BMI. But those relationships with birth weight were not observed. Children were at greater risk for overweight if at least ogle parent was overweight. The odds ratio for child overweight associated with maternal overweight was 2.41(95% CI = 1,13-5.IS), and those associated with paternal overweight 1.70(95% CI = 0.92-3.17). And parents' BMIs were positively correlated with children's BMI values and yearly BMI increment. In conclusion, overweight at early childhood and annual inclement in BMI can be important in predicting the prevalence of overweight and the risk that overweight will remain after 7 years of age. The risk of being overweight throughout the childhood increases by the parents'overweight.
