The purpose of this study was to evaluate the nutrient and food intake status in underweight female college students living in Seoul. 126 underweight(BMI<20) and 74 normal weight (20$\leq$BMI<25) students were asked for their daily food intake and eating habits by using 3-day food records and questionnaire. We analyzed the amounts of the nutrient intakes and food groups as the subjects. The mean of height and weight were 162.1cm and 49.0kg in underweight and 160.6cm and 54.9kg in normal weight subjects. The mean energy, iron, and vitamin A intakes among the students were smaller than RDA for Koreans. The mean calcium(p<0.01), sodium(p<0.05), and vitamin B$_2$(p<0.05) intakes in underweight subjects were significantly higher than those in normal weight subjects. Total food intakes of underweight and normal weight students were 1235.8g and 1078.1g, respectively. The mean of the pulse group in the underweight was significantly higher than that in normal group(p<0.01) Frequently consumed food or dish items of the subjects were Kimchi, cooked rice, and milk. In the relation between BMI and dietary factors, the BMI was found to have a significant negative correlation with calcium intake(p<0.05), pulse intake(p<0.01) and eating habit score(p<0.01) Eating habit scores about quantity of food and lipid intake showed a significant difference between underweight and normal students.

A survey was conducted to determine the relationship between BMI and the dining out behaviors of 316 university students in Seoul area for May and September, 2006. The subjects included 114 males and 202 females. General characteristics and BMI determined that of the students 56 (17.7%) were underweight, 222 (70.3%)were normal, 23 (7.3%) were overweight, and 15 (4.7%) were obese. There were differences in BMI according to age, sex, and major. Students majoring in natural science and engineering were 58.3% and 51% normal weight, respectively, and the next most common weight class was overweight. The non smoking group showed had primarily normal weight subjects followed by underweight-subjects, but the smoking group had primarily normal weight subjects followed by overweight subjects (P<0.001). The frequency of dining out for breakfast significantly correlated with BMI (P<0.05). The group that frequently dined out for breakfast were primarily of normal weight followed by overweight subjects, but the group that rarely dined out for breakfast were primarily of normal weight followed by underweight subjects(21.4%). Groups whose criteria for selecting dining out meals were flavor and price showed a higher percentage of underweight subjects than other groups. The group whose motivations for choosing dining out meals were convenience and habit showed a higher percentage underweight subjects than other motivations. The group that selected the Western food menu for dining out showed a higher percentage of underweight subjects than other food menu groups. And, the groups that selected Japanese and Korean food were primarily of normal weight followed by underweight subjects, but the result was not significant.

Background: Normal-weight obese women have a normal weight with relatively low muscle mass resulting from high body fat. We aimed to investigate the effects of core exercise on body composition, abdominal muscle thickness, trunk muscular endurance, and psychological factors in normal-weight obese women. Design: One group pre-, mid-, and post-test design. Methods: A total of 20 normal-weight obese women were recruited voluntarily. Core exercises were performed for 30 minutes, three times a week for 4 weeks. InBody measurements, ultrasound imaging, and clinical tests were used to assess body composition, abdominal muscle thickness, trunk and core muscular endurance, and psychological condition(satisfaction with appearance and self-esteem). The dependent variables were measured three times: before the intervention (pre-test), 2 weeks after the intervention (mid-test), and 4 weeks after intervention (post-test). One-way repeated measures ANOVA and Friedman test were used for statistical analysis. Results: Although there was no change in the body composition (p>0.05), thickness of the transversus abdominis and internal and external oblique muscles, endurance of the trunk flexors and extensors and core muscles, and psychological condition showed significant differences after the intervention (p<0.05). Conclusion: Our findings will help develop exercise programs for normal-weight obese individuals that utilize the beneficial effect of core exercises.

This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of healthy weights at community level. Nutrient intakes of 128 housewives were assessed by 24 hour recall method. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Subjects were divided to under-weight, normal-weight, over-weight groups by body mass index (BMI). Most under-weight groups evaluated as their current body images were normal. $41\%$ of normal-weight groups judged as their current body images were obese. Energy and fat intakes of over-weight group were significantly higher than that of under-weight and normal weight groups (p<0.05). However, carbohydrate and protein intakes showed no significant differences among the three groups. It appeared that active attitude toward change in nutrition attitude of normal weight group was significantly higher than that of under-weight group (p<0.05). There were no significant differences of food habit score, nutrition knowledge, and obesity habit scores among the three groups. The frequency of eating-out showed significant difference among three groups (p<0.05). Food habit scores were positively related to health-concerned attitude (r=0.174), convenience-concerned attitude (r=0.229) and food enjoyed attitude (0.213) and negatively related to obesity habit score (r=-0.206). Also, positive correlation of body fat mass with frequency of eatingout (r=0.213), instant food (r=0.227) and amount of meal (r=0.187) existed (p<0.05). We concluded that nutrition education programs for housewives should include specific strategies to modify unsound food behaviors and inappropriate perception of body image for a healthy weight.

In order to investigate how to maintain normal weight under independent living conditions, twenty female university students were enrolled and asked to complete a questionnaire over a 10- day study period. T-test, Spearman's correlation and multiple regression analysis were applied to describe characteristics of weight maintainers' habits on a daily basis. The results were as follows: They always comsumed small or moderate-sized meals. $2{\sim}3$ co-eaters usually had dinner together at home while not watching TV. They also showed healthy eating behaviors such as no snacking, very little amounts of soft drinks, coffee and alcohol consumption. The always normal weight maintainers, however, were not physically active at all. When being with co-eater(s), they ate larger-sized dinners (${\beta}$ = 0.585, $R^2$= 30.6), and the more co-eaters they had at the dinner table, the greater BMI they got (${\beta}$ = 0.547, $R^2$= 29.9). As a result of this study, encouraging young adult people to exercise on a regular basis is required, even though they seem to succeed in maintaining normal weight without being active physically. Further study is necessary to investigate how co-eaters would influence the amount of food eaten.

To elucidate the effect of antioxidant complex containing $\beta-carotene$, vitamin E, vitamin C, Ginkgo Biloba leaf extract and selenium on oxygen :tree radical production and detoxification system, rats were fed normal diet and normal diet with antioxidant complex 0.1%, 0.3% and 0.5% for 3 weeks. Feed efficiency ratio, changes in body weight, weight gain and amounts of feces of rat are similar in four groups. Liver weight per body weight and hepatic lipid peroxide weight increased in 0.5% group. However, hepatic glutathione contents in all antioxidant complex added groups were significantly increased compare with normal control group. On the other hand, the activity of xanthine oxidase was a little increased due to the amounts of antioxidant complex. Superoxide dismutase and gutathione peroxidase activity of 0.1% antioxidant complex added group were increased about $10{\sim}20%$ in comparison to normal control group. These results suggest that the supplementation of antioxidant complex 0.1% to basal diet may reduce the hepatic damage caused by free radicals.

Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

The principal objective of this study was to assess the weight control behavior, body shape satisfaction, and obesity stress depending on the degree of obesity in college students who applied for a weight control program. The average BMI of the participants was $21.4\;kg/m^2$ which was in the normal range, and 76.3% of the participants were of normal body weight. Ideal BMI in this participant was $18.1\;kg/m^2$, which is in the underweight range. In terms of body perception, participants generally overestimated their body weight. The overweight and normal weight groups were less satisfied with their body shape than was the underweight group. The overweight group also expressed fears of showing their bodies to others. Additionally, the overweight and normal groups exhibited higher obesity stress than the underweight group. 97.0% of participants were interested in weight control as a way to improve their appearance. They usually obtained their weight control information from the internet and mass media. More than 80% of participants had weight control experience, having undergone weight control attempts for duration of less than a month. However, after the discontinuation of weight control efforts, these participants regained the weight. As a consequence, they were generally unsatisfied with the outcomes of weight control programs. This study demonstrated that the college women who had applied for the weight control program were unsatisfied with their body shape owing to distorted notions of the ideal body shape, and these women had generally undertaken frequent efforts to control their body weights. These results underline the importance of educating college-aged women on proper body perception and the maintenance of healthy body weight and shape.

Background: This study was designed to determine the distance from skin to lumbar epidural space in obstetric parturients and whether weight, height, or PI (ponderal index, $kg/m^2$) might influence the epidural depth. Methods: 71 obstetric patients undergoing elective cesarean section during epidural anesthesia in L2-3 level were partitioned into groups according to their prepregnant BMI(body mass index), and in each group weight, height, PI, epidural depth were measured. Results: All patients were classified as underweight(n=18), normal(n=49), overweight(n=4) and no one was partitioned into obese group. the distance from skin to lumbar epidural space was found to be 3.7 cm(underweight), 4.1 cm(normal), 4.7 cm(over weight) and total mean distance was found to be 4.0 cm. The epidural depth had correlation with weight and height in underweight, and weight and PI in normal, but had no correlation with any measurements in overweight group. Conclusion: These results suggest body weight may be a useful parameter for predicting the distance from skin to lumbar epidural space in underweight and normal weight obstetric parturients.

Objectives: The purpose of this study was to assess the characteristics of body weight perception and physiological index in young adult women. Methods: Subjects were 283 Korea women. Data was from the 2005 Korean National Health and Survey. Three groups-low normal and overweight-were based on Body mass index(BMI). General characteristics, health status perception, weight control behavior and physiological index such as BMI, total cholesterol, high-density cholesterol (HDL), low-density cholesterol (LDL), triglyceride, systolic and diastolic blood pressure, and waist circumference were compared. Data were analyzed by t-test, $x^2$-test and ANOVA using SPSS program. Results: Of the normal weight group, 28.7% of subjects perceived themselves as overweight. Of the low weight group, 30.3% regarded their weight as normal weight. Of the overweight subjects, weight control was attempted by exercise (50.1%) and food reduction (77.1%). Significant group-related differences were evident in HDL, LDL, triglyceride, systolic blood pressure and waist circumference among three groups. Conclusions: Perception and attitude regarding body weight can be inaccurate. A weight control program should consider the relation of physiological index and weight based on BMI.
