Purpose: The purpose of this study was to identify the relationship between BMI, perceived weight and health status of the nursing students by finding the discrepancy between obesity by measuring BMI and students' perception of their weight. Method: The data were obtained by a questionnaire from 211 female nursing students of G college, Inchon, Korea, and by measuring their heights and weights. Result: The BMI of the 1st grade students($20.74kg/m^2$) was higher significantly than that of the 3rd grade students($19.65kg/m^2$). The difference between the obesity by BMI and perceived weight was significant. The concordance rates between obesity by BMI and perceived weight were 22,9%, 59.5%, 90.9% and 50% in underweight, normal, overweight, and obese students respectively. The students perceiving themselves overweight showed higher physical health status significantly than the students perceiving themselves underweight. There was a statistically significant correlation between BMI and physical health of the students. Conclusion: BMI of the nursing students has a significant influence on their physical health. Also there were significant discrepancies between the obesity by BMI and perceived weight.

Objectives: The purpose of the study is to investigate the relationship between body mass index(BMI) and periodontal disease in Korean adult from the data of the fifth Korea National Health and Nutrition Examination Survey(KNHANES). Methods: The subjects were 3,309 adults from 25 ro 45 years old in the fifth KNHANES. The subjects were divided into three BMI categories: normal weight 1,549(BMI ${\leq}22.9kg/m^2$), overweight 792(BMI $23.0-25.0kg/m^2$) and obesity 968(BMI ${\geq}25.0kg/m^2$). Periodontal disease was assessed by community periodontal index(CPI) and periodontitis was defined as ${\geq}$ code 3. Results: Increased BMI adults had no significantly higher prevalence of periodontitis than those having normal body weight after adjusting for variables; the odds ratio(OR) was 1.06 in overweight and 1.23 in obesity. BMI and periodontitis had no significant relation to increased age, but the age increase tended to have high odds ratio. Women had a higher OR than men. Conclusions: Through this study, it is necessary to analyze the relationship between the obesity index and periodontitis in the further study.

Purpose: This study examined the relation of BMI to lipid metabolism and health promoting behavior in middle-aged women. Methods: The subjects were 113 women between 40 to 60 years of age. The data was collected from April 2003 to July 2004. BMI was measured using body composition analyzer and lipid metabolism were measured using automatic biochemical analyzer. Health promoting behavior was collected using a structured questionnaire. The SPSSWIN(10.0 version) program was used to analyze the data and get the descriptive statistics and Pearson's correlation coefficients. Results: BMI was negatively correlated with HDL-c and positively correlated with triglyceride, but there was no significance between BMI and total cholesterol. There was no significance of correlation between BMI and total health-promoting behavior. Conclusion: This study showed that BMI is meaningful in the identification of the high risk women to prevent HDL-c & triglyceride metabolism disturbance, but additional research is needed to study the correlation between BMI and health promoting behaviors in middle-aged women.

Interfacial and microfailure properties of carbon liber/bismaleimide (BMI) composites were evaluated using both tensile fragmentation and compressive Broutman tests with acoustic emission (AE). Since BMI is rather difficult matrix to apply for the conventional fragmentation test because of its too low elongation and too brittle and high modulus properties, dual matrix composite system was applied. After carbon fiber/BMI composite was prepared for rod shape by controlling differing curing stage, composites rod was embedded in toughened epoxy as outer matrix. The typical microfailure modes including fiber break, matrix cracking, and interlayer failure were observed during tensile testing, whereas the diagonal slippage in fiber ends was observed during compressive test. On the other hand, AE amplitudes of BMI matrix fracture were higher than carbon fiber tincture under tensile test because BMI matrix has very brittle and high modulus. The waveform of signals coming from BMI matrix fractures was consistent with AE amplitude result under tensile tests.

본 연구의 목적은 방사선 조사 용적 내 포함되는 소장의 용적 감소를 위해 복부판(Belly board, 벨리보드)과 소장변위도구(Small Bowel Displacement Device, SBDD)를 사용한 직장암 환자에서 방사선 치료 영역 내 포함되는 소장의 용적과 비만도 와의 상관성을 보고, 비만지표의 적용을 통해 SBDD의 사용지표를 삼고자 한다. 실험은 2012년 1월부터 4월까지 수술 전 혹은 수술 후 벨리보드와 SBDD를 사용해 골반부위에 방사선치료를 받은 29명의 직장암 환자를 대상으로 분석하였다. 방사선 치료는 3문 조사로 시행하였으며 1.8 Gy의 분할선량으로 중심점에 45 Gy를 조사한 계획만을 분석하였다. 환자의 키, 몸무게, 체질량지수(body mass index, BMI), 허리 엉덩이 둘레비(waist hip ratio, WHR)를 측정하여 비만도를 조사하였다. 조사되는 선량의 90%이상 들어가는 소장의 용적(high dose volume of small bowel, $HDV_{sb}$)과 33%이상 들어가는 소장의 용적(low dose volume of small bowel, $LDV_{sb}$)을 방광의 총 용적(total volume of bladder, $TV_{bladder}$) 및 비만도에 따라 비교하여 그 상관관계를 통계학적으로 분석하였다. 분석결과 수술여부 및 성별 WHR은 $HDV_{sb}$, $LDV_{sb}$에 크게 미치는 영향이 없었고 $HDV_{sb}$, $LDV_{sb}$와 BMI(p=0.031/0.083), $TV_{bladder}$ (p<0.05)는 통계적으로 유의하였다. BMI가 $HDV_{sb}$와는 유의 하지만 $LDV_{sb}$와는 크게 유의하지 않았다. (p=0.031, p>0.05) BMI는 $HDV_{sb}$와 음의 상관관계(${\beta}$=-0.402)가 있었으며 $TV_{bladder}$는 $HDV_{sb}$, $LDV_{sb}$와 음의 상관관계(${\beta}$=-0.497/-0.522)가 있었다. 특히 BMI 23 미만인 경우(BMI Group2)보다 그 이상인 경우 $HDV_{sb}$에 영향을 미치며 음의 상관성(${\beta}$=-0.525)이 있었다.($LDV_{sb}$, $HDV_{sb}$와 유의확률 각각 p=0.059, p=0.027) BMI가 23 이상인 집단(BMI Group1)에서는 $TV_{bladder}$와 $HDV_{sb}$, $LDV_{sb}$가 통계학적으로 유의하였고(p<0.04) 음의 상관성을 보였다. 비만지표인 BMI가 23 이상인 과체중 및 비만군의 직장암 방사선 치료 시 벨리보드와 SBDD를 동시에 사용하는 경우 조사용적 내 포함되는 소장의 용적을 감소시키는데 더 효과적이었다. 그러므로 벨리보드를 사용하는 직장암의 방사선 치료 시 BMI 23 이상인 한국인 환자에게는 소장변위도구를 동시에 사용 할 것을 권장한다.

This study was carried out to evaluate high-school students' nutrient intakes according to the status of body mass index, and to analyze the Physical health status. The volunteers were 560 high school students in 8 provinces, but 511 students were analyzed. It was used questionnaire method as an instrument tool. The questions were composed with socio-demographic characteristics, physical health condition by CMI. and the evaluation of food consumption by 24 hours recall method. Anthrophometric measurement of height and weight was used the data of health chart of each school-class. The family situation of the subjects was mostly nuclear family(73%), agricultural work(53%), and normal living situation(75%). The students of the BMI range of 18-23 were 71%. but those of the overweight(over 23) were 15%. The individual characteristics were different in BMI. Female and third grade students were more of BMI scores. The overall nutrient intakes of students were low compared with Korean RDA of adolescent. especially iron. calcium. vitamin A, and riboflavin. The mean adequacy ratio(MAR) of nutrient intakes was 0.45$\pm$0.23 only. The energy nutrients, ash, and vitamin A intakes were significantly different according to the different BMI groups. But the other mineral and vitamin intakes were not different according to BMI. By the correlation of individual characters with BMI, height was negatively and weight and school grade were positively correlated, but sleeping time and study accomplishment were not correlated. By the correlation of nutrient intakes with BMI, there were negative correlation with the intakes of energy, carbohydrates, potassium, and thiamin. According to this results, We concluded that Korean high-school students living in rural were lower intake of nutrients(iron, vitamin A, and riboflavin) and unbalanced nutrient intakes(MAR of 0.45$\pm$0.23). The state of lower intakes of energy nutrients and vitamin A intakes in higher BMI group mean the students spend their effort to reduce BMI for avoiding obesity. But they need to balanced diet. and good nutrient intakes. These situations would be necessary for students to ameliorate quality of living in rural.

Objectives: The object of this study was to determine the relationship between body mass index (BMI) and early menarche in adolescent girls in Seoul. Methods: A retrospective study was conducted with 144 middle school students in Seoul who provided informed consent. We measured their body composition, and used the questionnaire survey method for data collection from November to December 2008. Past elemental body composition data were collected from elementary school health records of first year of middle school. Results: The early menarcheal group was taller and heavier than the late menarcheal group (p<0.05 from 8-12 years old). The body fat percentage (%), BMI were higher in the early menarcheal girls than the late-menarcheal girls (p<0.05, age at 13). In the result of multiple logistic regression, the BMI at the age of 8 and 9 was associated with early menarche after adjusting for birth weight, breast feeding and age at menarche of the mother (BMI at the age of 8: p for trend=0.01, BMI at the age of 9: p for trend=0.04). An increase in BMI from 7 to 8 year was associated with early menarche after adjusting for birth weight, breast feeding, age at menarche of the mother (p for trend=0.048). Conclusions: The BMI at the age of 8 and 9 was associated with the early menarche of girls and increase in BMI from 7 to 8 year was associated with the early menarche of girls. These results suggest that BMI and increase in BMI before menarche cause early menarche. Although this study does not represent all Korean adolescent girls, it is one of the few studies that have investigated the temporal relationship between BMI and early menarche.

Background/Aims: Obesity is a risk factor for gastroesophageal reflux disease (GERD), with several studies demonstrating positive associations between body mass index (BMI) and GERD symptoms. However, little is known about the effect of BMI changes on erosive esophagitis (EE). In this study, we investigated whether BMI reduction could resolve EE. Methods: A retrospective cohort study was performed to assess the natural course of EE according to changes in BMI. Participants undergoing health check-ups from 2006 to 2012 were enrolled, and 1,126 subjects with EE were included. The degree of esophagitis was measured by upper endoscopy and serially checked over a 5-year follow-up. Logistic regression and Cox proportional hazards models were used to investigate the association between BMI reduction and EE resolution. Results: Substantial weight loss is associated with EE resolution. The adjusted odds ratio for EE resolution was 1.44 (95% confidence interval [CI], 1.09 to 1.92) among participants with a decrease in BMI compared to those with no decrease in BMI. The EE resolution rate was related to the degree of BMI reduction. The effect of weight loss on EE resolution was higher among subjects who lost more weight. Compared with subjects with no decrease in BMI, the hazard ratios for EE resolution were 1.09 (95% CI, 0.89 to 1.35), 1.31 (95% CI, 1.01 to 1.72) and 2.12 (95% CI, 1.44 to 3.12) in subjects with BMI reductions of ${\leq}1$, 1-2, and >$2kg/m^2$, respectively. Conclusions: EE resolution is associated with a decrease in BMI, and weight loss is potentially an effective GERD treatment.
