  • Purpose: The purpose of this study was to identify Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 Second ($FEV_1$), $FEV_1$/FVC according to obesity in young adult women. Method: Height, weight, body mass index (BMI), and percent body fat (PBF) were obtained by using bioelectrical impedance analysis. Neck circumference (NC), waist circumference (WC) and spirometric values (FVC, $FEV_1$, $FEV_1$/FVC) were obtained for 135 women college students who were healthy and non smokers. Results: Mean BMI and PBF were $21.8kg/m^2$ and 30.5%. Obesity prevalence according to BMI and PBF were respectively 13.3%, and 50.9%. Lean body mass (LBM) was positively correlated with FVC, $FEV_1$, and PBF was negatively correlated with FVC, $FEV_1$ and $FEV_1$/FVC. FVC and $FEV_1$ of the underweight or obese group were lower than those of normal weight group. Conclusion: PBF, but not BMI, is negatively associated with pulmonary function in women college students.

  • Osteoporosis is a disease that increases the fracture rates and a major cause of increased mortality and morbidity in the elderly people. This study is to determine which components of body composition and metabolic syndrome risk factors are important to bone health, we analysed the relationship among bone mineral density (BMD), body composition and metabolic syndrome risk factors in females. Totally 630 females participated in a medical check-up program (mean age 47 years) were selected for this study. Body composition analysis was performed by segmental bioelectrical impedance method, muscle mass, and percent body fat were measured. We also measured metabolic syndrome risk factors including abdominal obesity, HDL-cholesterol, triglyceride, blood pressure and fasting glucose level. Metabolic syndrome was defined by NCEP-ATP III criteria. The lumbar spine and femoral neck BMD were measured using the dual energy X-ray absorptiometry. Osteopenia and osteoporosis were observed in 180 and 51 persons, respectively. Muscle mass and HDL-cholesterol decreased in osteopenia and osteoporosis groups compared to the control group, and the grade was shown progressively by the symptoms. Significant positive correlation between BMD and muscle mass was observed. Multi variable regression analyses showed that % body fat and muscle mass were independent predictors of BMD after adjustment of age, height and weight. In conclusion, the BMD showed negative correlation with the metabolic and body composition was associated with BMD.

  • Purpose: The purpose of this study was to predict measuring site suited for abdominal skin fold thickness (ASFT) by measuring the distribution of abdominal subcutaneous fat thickness (AScFT) and ascertain the correlations among obesity indicators. Methods: The size of analysis materials was 124 secondary data measured by ultrasonic device, bioelectrical impedance analyzer and caliper. Data were analyzed using t-test, and Pearson's correlation. Results: The average of AScFT was 10.63± 6.79mm with its range 1.39-36.16 mm, and AScFT of female and of central parts were thicker than those of male and outer parts in the abdomen. The average of ASFT was 29.26±12.59 mm. Site 5 on Figure 1 was most similar to the average of AScFT in both sexes. Body mass index (BMI) and waist hip ratio (WHR) were 23.65±3.98 and 0.88±0.05 respectively. The body weight, BMI, WHR, visceral fat, ASFT vs AScFT revealed in significant correlation (r= .29, r= .55, r= .39, r= .33. r= .29). Conclusion: BMI and WHR seem more useful than other obesity indicators, when obesity control is necessary for Type 2 diabetes patients. Site 5 on Figure 1 is most suitable site to measure ASFT.

  • The purpose of this study is to report a case of a patient with pattern identification of liver fire flaming upward and metabolic syndrome improved by Korean medicine. The patient felt completely lost. She was treated for headache, insomnia, and metabolic syndrome with Korean medicine and psychotherapy. Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Pattern Identification Tool for Insomnia (PIT-Insomnia), Minnesota multiphasic personality inventory-2 (MMPI-2), and bioelectrical impedance analysis (BIA) were used for assessment. During treatment for six months, the patient stopped taking headache pills. Her blood pressure was stabilized. Her body weight, body fat, body mass index (BMI), and visceral fat decreased significantly. The sum of ISI, PSQI, PIT-insomnia also decreased significantly. Her Ego strength increased in the MMPI-2 supplementary scale. We assume that Korean medicine treatment through acupuncture, herbal medicine, and psychotherapy is effective in treating pattern identification of liver fire flaming upward and metabolic syndrome.

  • Objectives : The aim of this study was to suggest a new method to estimate the resistance by acupoint compositions by using the multi-frequency bioelectrical impedance analysis(MF-BIA) of 5 kHz, 50 kHz and 200 kHz within 2 cm of acupoints as a local segment. Moreover, we try to confirm the relation to between measured resistance at skin surface and measured resistance by various manual acupuncture needle insertion depth. Methods : Ten male subjects participated in this study. We measured the resistance at left/right ST36 at skin surface and various manual acupuncture needle insertion depth(skin, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm and 30 mm). Results : It was also observed that the all measured resistances were the highest at 5 kHz and the lowest at 200 kHz. There were significant differences at 5 kHz, 50 kHz and 200 kHz between measured resistance at skin surface and measured resistance by various manual acupuncture needle insertion depth(p<0.05). There was no significant difference in the left and right identical acupoints under the identical condition(p>0.05). Conclusions : We conclude that the measured resistance at skin surface has limitation as to reflect the information of tissue. However, the measured resistance at each frequency was changed as similar pattern by different insertion depth. Hence, we confirmed the possibility of assumption on information of tissue which was expected to locate an acupoint.

  • Objectives: The Korean Genome and Epidemiology Study (KoGES), a multicenter-based multi-cohort study, has collected information on body composition using two different bioelectrical impedence analysis (BIA) machines. The aim of the study was to evaluate the possibility of whether the test values measured from different BIA machines can be integrated through statistical adjustment algorithm under excellent inter-rater reliability. Methods: We selected two centers to measure inter-rater reliability of the two BIA machines. We set up the two machines side by side and measured subjects' body compositions between October and December 2007. Duplicated test values of 848 subjects were collected. Pearson and intra-class correlation coefficients for inter-rater reliability were estimated using results from the two machines. To detect the feasibility for data integration, we constructed statistical compensation models using linear regression models with residual analysis and R-square values. Results: All correlation coefficients indicated excellent reliability except mineral mass. However, models using only duplicated body composition values for data integration were not feasible due to relatively low $R^2$ values of 0.8 for mineral mass and target weight. To integrate body composition data, models adjusted for four empirical variables that were age, sex, weight and height were most ideal (all $R^2$ > 0.9). Conclusions: The test values measured with the two BIA machines in the KoGES have excellent reliability for the nine body composition values. Based on reliability, values can be integrated through algorithmic statistical adjustment using regression equations that includes age, sex, weight, and height.

  • 목적 : 경혈의 임피던스를 측정하여 경혈의 특이성을 확보하고자 다수 연구가 진행되어왔다. 직류전압과 교류전압을 자극하여 단순히 경혈이 위치한 피부 임피던스를 측정하는 방식이 아닌 Multi-Frequency Body Impedance analysis(MF BIA) 기법을 이용하여 생체 구조 성분(세포 외액, 세포내액의 저항성분 그리고 세포막의 용량성분)을 추출하는 방법을 이용하여 경혈의 특이성을 확보하고자 한다. 인체 내 생체 이온 변화가 발생하였을 시, 경혈이 비경혈에 발생 전/후 높은 변화율이 관찰될 것이라는 가정을 하에, 생체 이온 변화를 유도하기 위하여 근피로를 유발하였으며, 유도 전/후의 생체 구조 성분을 비교 분석하였다. 방법: 대퇴직근에 근피로를 유도하기 위하여 건강한 대학생에게 Knee extension/flexion의 등속도 운동을 통하였다. 생체 이온 변화를 확인하기 위하여 젖산을 측정하였으며, 피험자마다 동일한 근피로를 유발하기 위하여 EMG(electromyogram) 분석을 통하여 peak torque와 median frequency를 분석하였다. 근피로 유발 24시간 이후까지 젖산과 peak torque와 median frequency을 측정하였으며, 각 단계마다 복토(ST32), 음시(ST33) 과 인접한 비경혈 2개에 대하여 생체 구조 성분 또한 측정하였다. 결과 : 젖산과 peak torque와 median frequency은 24시간 이후 근피로 유발 전으로 회복되었다. 세포외액 저항성분의 경우 비경혈에 비하여 복토(ST32)에서 생체 이온 변화에 따라 높은 변화율이 관찰되었으나, 음시(ST33) 에서는 비경혈에 비하여 낮은 변화율이 관찰되었다. 세포내액 저항성분은 경혈과 비경혈 사이 유의한 차이가 관찰되지 않았다. 복토(ST32)에서 세포막의 용량성분이 높은 변화율이 관찰되었지만, 음시(ST33)와 인접한 비경혈간의 뚜렷한 차이가 확인되지 않았다. 결론 : 생체 이온 변화에 따라 인접한 비경혈과 비교해보았을 시, 경혈에서의 상대적으로 높고 낮은 혹은 유사한 변화율이 관찰되었다. 따라서 경혈의 특이성을 확보하지 못하였으며, 생체 구조 성분 추출을 통하여 세포 이온 변화에 따른 경혈의 특이성을 확보하기에는 한계점을 가지고 있다고 결론을 내렸다.
