Both cardiovascular diseases caused by decreased body composition and arterial compliance and falling induced by loss of muscle mass are frequent occurrences in the elderly. Therefore, elderly people are advised to perform elastic band resistance exercises to improve their body composition and arterial compliance. Thus, the purpose of this study was to examine the effects of 12 weeks of elastic band resistance training on the body composition, arterial compliance and falling index in elderly females (> 65 years). The elastic band resistance exercise program was administered 3 times per week for 60 minutes each time for 12 weeks. In addition, the exercise intensity was set to 11-14 on the Borg scale (6-20). Before and after the training period, the body composition (body weight (BW), muscle mass, % body fat, body mass index (BMI)), arterial compliance (ankle brachial index (ABI) and pulse wave velocity (PWV)) and risk of falling index were determined. (After the program?), the BW (p=.003), BMI (p=.002), PWV (p=.017) and risk of falling (p=.037) in the exercise group were significantly reduced, whereas the BW (p=.009) and BMI (p=.009) in the control group were significantly increased. In conclusion, the body weight, BMI and arterial compliance of elderly females were positively changed by the elastic band resistance training. Thus, the elastic band resistance exercise may be useful for elderly people to prevent metabolic syndrome and cardiovascular diseases and to reduce their risk of falling.

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.

Purpose: This descriptive study was designed to investigative BMI(body mass index) and health behaviors in college students. Method: The subjects of this study consisted of 189 college women and 125 college men. Data were collected using self-report questionnaires from April 1 to April 10, 2005. Data were analyzed by the SPSS /pc 10.0 statistical program using frequency, t-test, $x^2$-test. Result: College women perceived themselves as more obese than indicated their BMI, and the most effective weight control factor was their response to images of people presented in the media. In general college men present more salubrious behavior than college women. Conclusion: The results suggest that health care providers need to educate female students about heathy behavior as well as the normal weight in BMI.

With the success of the genome-wide association studies (GWASs), many candidate loci for complex human diseases have been reported in the GWAS catalog. Recently, many disease prediction models based on penalized regression or statistical learning methods were proposed using candidate causal variants from significant single-nucleotide polymorphisms of GWASs. However, there have been only a few systematic studies comparing existing methods. In this study, we first constructed risk prediction models, such as stepwise linear regression (SLR), least absolute shrinkage and selection operator (LASSO), and Elastic-Net (EN), using a GWAS chip and GWAS catalog. We then compared the prediction accuracy by calculating the mean square error (MSE) value on data from the Korea Association Resource (KARE) with body mass index. Our results show that SLR provides a smaller MSE value than the other methods, while the numbers of selected variables in each model were similar.

This study was designed to investigate the relationship between body mass index and food habits of college students. For this purpose, 358 students of Kangweon University were asked to fill out the questionnaires for food habits and weight control. The results are summarized as follows ; The rate of underweight, normal and obese was 16.5, 65.1, 18.4%, respectively. Food habits score of obese females were lower than normal or underweight females. Male subjects did not show significantly different scores among the three groups. Female obese subjects have lower scores than the other groups on the eating time, seaweed intake, protein intake and vegetable intake. Male obese subjects have nutritious meals and more eating time than normal and underweight males. College students are the early stage of adult life and their food habits, food behaviors and life style will continue in later life. Therefore, college students need more nutritional knowledge, positive dietary attitudes and modified life styles to prevent and treat obesity.

Purpose: This study is to investigate perceived stress, depression, body mass index (BMI), and nutrient intakes of soldiers in the army. Methods: The subjects were 301 soldiers recruited from two divisions of the army in Kangwon-Do. The data was collected from August 3 to 9, 2009. Perceived stress, depression, lifestyle, dietary habits, BMI, and nutrient intake were assessed. Results: Subjects' distribution for normal weight, underweight, overweight, and obese was 67.4%, 0.7%, 16.3%, and 15.6%, respectively. BMI was related to class, service branch, duration of military service and being on a diet, whereas BMI was not found to be related to perceived stress, and depression. Some nutrient intakes such as dietary fiber, vitamin C, and Calcium was related to depression. Conclusion: This study suggests that soldiers need to undergo stress, depression management, and a nutritional education program.

Purpose. The purpose of this study was to identify the relationship between fatigue and nutritional status in patients undergoing radiotherapy. Design. A correlational and crossectional study design was used. Method. One-hundred-fifty-one subjects with cancer receiving radiotherapy were recruited from a university hospital in Chonan, Korea. Fatigue was measured using Piper's Fatigue Scale (PFS). The parameters for nutritional status included body weight, body mass index, hemoglobin, and lymphocyte counts. Cancer stage was controlled in analyzing the differences in fatigue, body weight and body mass index. Results. The patients who experienced most fatigue were in their fifties, employed, had head and neck cancer, received radiotherapy on the head and neck, and had concomitant chemotherapy. Disease-related characteristics such as cancer type, and treatment type were frequently related to poorer nutritional status. Patients who showed poorer nutritional status, such as those with lower body weight, lower body mass index and lower hemoglobin levels were more fatigued than those who did not exhibit such characteristics. Lymphocyte counts did not correlate with fatigue. Conclusion: The findings can be used by nurses who are taking care of patients undergoing radiotherapy. Considering the relationship between fatigue and nutritional status, nurses can identify the risk group most vulnerable to fatigue and malnourishment in order to provide appropriate interventions for them.

The purpose of this study was to identify the correlation and level of Body Mass Index, Body Shape Dissatisfaction, Eating Behavior in college students. Methods: A total of 383 students were asked. The survey was analyzed by SPSS Win 21.0 program. 293 were female students and most of the students were normal in BMI(58.2%), and underweight students were the next(14.9%). There were positive correlation between body shape non satisfication and eating behavior and BMI(r=.587, p=.000; r=.174, p=.001), and negative correlation between body shape non satisfication and age and sleeping time. According to BMI the body shape non satisfication was different in normal and 1 stage obesity students. and 2 stage obesity and under weight students (F=2.993, p=.019;F=2.993, p=.109). As a result of this study, students with body mass index overweight have low body satisfaction, so it is necessary to educate the right dietary exercise therapy for weight management. And even underweight groups should be mediated so that they undergo normal diet behaviors, rather than restrained dietary behaviors, to maintain health.

Purpose: The purpose of this study was to investigate the relationships between the herbal medicines used for women in puerperium on postpartum care, Kami-Saenghwatang(SHT) and Kami-Bohertang(BHT) and postpartum body composition change. We also examined the influence of gestational age, the number of parity and the route of delivery for gestational weight gain and postpartum weight loss. Methods: 239 women followed by postpartum care center. Variety factor s were conformed and then checked body composition analysis. 8 weeks later, we followed up body composition of 36 women among the former checked. and additionally asked the body weight of another 42 former checked women by telephone call. Results: $Mean{\pm}S.D$(standard deviation) of pre-pregnancy weight is $55.22{\pm}8.98kg$, $Mean{\pm}S.D$ of gestational maximun weight is $69.26{\pm}9.77kg$, $Mean{\pm}S.D$ of weight loss in postpartum 8 weeks(means sub-tract postpartum 1 week weight from postpartum 8 week weight) is $57.86{\pm}8.60kg$. The number of parities had corrrelation with gestational weight gain. Age, number of parities and route of delive were not significantly correlated with postpartum weight loss during 8 weeks after delivery, and also it was not correlated with body water mass, body fat mass, body mass index and body weight on postpartum 8 weeks whether they treated with SHT and BHT. conclusion: It was not correlated with body water mass, body fat mass, body mass index and body weight on 8 weeks postpartum whether they treated with SHT and BHT.
