This study was performed to identify the nutritional status and eating behaviors of underweight adolescent females aged 15 to 19 years. The subjects were selected using data from 2001 NHANS of Korea, and included 28 underweight and 160 normal-weight subjects. We found that the underweight group had significantly lower weight (9.8 kg), waist (6.9 cm), and hip circumference (7.2 cm) values than the normal-weight group; however height and waist-hip ratio were not different. Serum indices were within normal ranges and showed no differences between the two groups. The energy and nutrient intakes of most of the subjects were considered poor. For intake levels, the proportion of subjects below the EAR, NAR and INQ of each nutrient were also not significantly different between the groups. There were no differences in frequency for skipping meals, snacking, and eating-out between the groups. When comparing food frequency data for 62 food items, the underweight group consumed significantly more often of eggs, dried anchovies, mackerel, shellfish, and mushrooms than the normal-weight group. The former also had significantly less excercise/walking, more diet-control, and more rest/sleep than the latter. Subjects in both of two groups perceived their body images as over weight, so they practiced diet-control to reduce body weight, which is considered harmful as a healthy weight. In conclusion, the underweight group showed no differences in items of biochemical indices, nutrient intakes, and many dietary behaviors, but subjects revealed significantly higher food intake frequencies for several protein foods, as well as less excercise/walking, and more rest/sleep than the normal-weight group.

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.

Objectives: The purpose of this study was to find out the relation factors of weight control behaviors, mental health status and body image perception in adolescents and to use basis data of health promotion for adolescents. Methods: This study used data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The subjects were 653 between 12-19 age. Data analysis was done with SPSS/WIN 19.0 using Chi-square test, and Logistic regression. Results: The result is as follows. The case of female adolescents, abnormal perception of body image was significantly higher on weight reduction effort and normal weight, low weight in BMI. The case of male adolescents, abnormal perception of body image was higher on normal weight in BMI. Conclusions: The adolescents tend to do unreasoning weight loss behavior without properly perception for their body image. Therefore, we suggest that adolescents be provided social support for positive body image and be developed perception program with the importance of inner values.

The objective of this study was to evaluate the effect of exogenous ghrelin on the behaviors, weight gain, and feed intakes of weanling piglets. A total of 25 pairs of Duroc$\times$Landrace$\times$Large White piglets weaned at 21 days of age were used in this experiment which finished on day 36. Each pair of healthy piglets from the same litter with similar body weight and of the same gender were selected and randomly arranged to ghrelin or control groups. Thus, there were 50 piglets (ghrelin 25; control 25) kept in 10 pens (ghrelin 5; control 5) and 5 piglets per pen. Initial body weight of the pigs did not differ between the control and ghrelin treatment ($7.43{\pm}0.17kg$; p = 0.81). Experimental pigs were infused with ghrelin ($1{\mu}g/d$ pig) via the marginal ear vein between 0750 and 0800 h at 22, 23, 24 days of age. Control pigs were infused with 0.9% saline. Feed consumption was measured on days 23, 24, 25, 29 and 36. Body weight was measured on days 22, 23, 24, 25, 29 and 36. Behavior data of individual piglets were collected by real-time observation from 0800-1500 h through remote supervisory equipment at 22, 23 and 24 days of age. The results indicated that ghrelin infusion could increase drinking (p<0.05) and lying behaviors (p<0.01) and decrease mounting behaviors (p<0.05). No significant influence of ghrelin was found on average daily weight gain (ADG) and average daily feed intake (ADFI) in this experiment (p>0.05). In conclusion, exogenous ghrelin by the method above and at the dosage of $1{\mu}g/d$ pig could cause a variety of behavioral effects, but not improve performance of weanling piglets.

Purpose: To provide the epidemiological information for developing preventive programs encourage appropriate eating and weight control behaviors. Method: 349 college students in Seoul were administered self-report question- naires to examine eating habits, trend of disordered eating, weight reduction practice and body size evaluation from September to October 2002. Data were analyzed by SAS program for frequency, t-test, ANOVA with Scheff test. Result: The mean eating score was moderate and it differed by subjects' characteristics. The mean score of EAT-26 was relatively lowered, and 3.4% of the subjects score showed disordered eating behavior. It differed significantly by subjects' general characteristics. 30.4% of total sample were currently trying to lose weight and had interested in trying to lose weight. EAT-26 was significantly different by weight reduction practices and interest. Perceived body size differed by the score of eating habit and EAT-26. Conclusion: It can be suggested weight preoccupation have a relation to eating habits, weight control practice and disordered eating. Further study is recommended educational interventions targeting at-risk subjects.

Most of college women are interested in their appearances, and those whose body weights are normal or even underweight try to lose weight. Many methods for weight control diets practiced by college women are unsound and irrational so that some side-effects should be watched out. The present study was aimed to investigate methods of diets, food habits, behaviors, and side effects of weight control and to suggest sound weight loss schemes for college women. The subjects were 353 college women living in Taegu and Kyung Buk area, comprising 178 women who have tried weight control diets and 175 women who have not tried diets. The items included in questionnaires were food habits, food behavoirs, food frequency, physical activity status, 24-hour daily activity record, height, weight, etc., and the survey was conducted in September 1997. There was no difference in body mass index between college women who have tried diets(20.1$\pm$2.26) and women who have not tried diets(19.3$\pm$1.58), and 24.2% of those who have tried diets had body mass index under 19. The leading reason for diets was to make better fitting for costumes(67%). While women who have tried diets also tried to exercise more, they tended to overeat than women who have not tried diets. Mean of food habit scores(9.33 vs 9.32) which corresponded to "poor" habit and food frequencies were not different with or without experiences of diets. This indicated that diets were not related to actual changes of food habits and food intakes. Diet methods used frequently by college women were relying on special diet foods(25.4%), fasting(24.9%) and exercise(22.6%). Trying both exercise and diet was practiced by only 5.1% of the subjects who have tried diets. The duration time of diets was mostly in the range of 1 week to 1 month, and the longer diet period was, the more weight loss was. The frequent side effects due to diets were anemia(41.8%) and enervation(23.7%). Activity coefficients were lower in those who have tried diets(1.38$\pm$0.13) than those who have not tried diets(1.41$\pm$0.19). Women who have tried diets spent more time on reading newspapers and magazines and on watching TV. This study indicates that college women who have tried diets practiced irrational diets for weight reduction and experienced undesirable side-effects. Therefore scientific and systematic weight reduction programs accompanying balanced diets and proper exercise with behavior changes should be developed.

Purpose: This ethnography was done to explore patterns of weight management behavior among adults using obesity clinics. Methods: The participants were 12 adults who were overweight or obese and 2 family members. Data were collected from iterative fieldwork in the obesity clinics of two hospitals. Data were analyzed using text analysis and taxonomic methods. Results: Weight management behaviors among participants varied according to the recognition of the body and motivation for weight control, Participants' behavior was discussed in the socio-cultural context of obesity. Patterns of weight management behavior among participants were categorized by focus: strategic self-oriented type including managements for the body as a social asset and for health, selective neglect type, and passive group value-oriented type including type dependent on others and managements for beauty. Conclusion: Participants' weight management behavior was guided by folk concepts of body and health. and constructed within the socio-cultural context. It is necessary for health care providers to understand physical and psychological problems arising from the repeated trials, excessive control of weight, and Western cultural discourse on beauty ideals among adults who are overweight or obese. Therefore, interventions should be tailored to address individual and community needs.

This study was performed to investigate the body image perception by BMI and the dietary behaviors in 803 college students(408 males and 395 females). The degree of obesity was divided into an underweight group with BMI less than $18.5kg/m^2$, a normal group with BMI of $18.5{\sim}22.9kg/m^2$, an overweight group with BMI of $23{\sim}24.9kg/m^2$ and an obese group with BMI over $25.0kg/m^2$. The average ages of subjects were 22.9 years in males and 20.2 years in females. The average weight and height of male subjects were 175.3 cm and 69.6 kg, respectively and those of female subjects were 162.5 cm and 52.0 kg, respectively. The average BMIs of male and female subjects were $22.6kg/m^2$ and $19.7kg/m^2$, respectively. The distribution of subjects who perceived their current body image as ideal body image was 25.7% in males and 10.9% in females, showing that the body image satisfaction of male subjects was 1.5 times higher than that of female subjects. Body image perception for their own bodies was mostly shown as the average or standard shape both in males and females with 64.2% and 54.2%, respectively, but males showed a higher perception rate than females and 31.1% of females and 19.5% of males perceived their bodies as lean shape(p<0.01). The body image satisfaction was 4.20 in males and 3.70 in females, showing more satisfaction in the male subjects(p<0.001). The correlation between body image and physical variables in male subjects indicated that CBI and IBI showed statistically significant correlation and also BMI showed statistically significant correlation with IBI(p<0.001) and CBI(p<0.001). The frequency of eating out increased as the frequency of skipping meals increased(p<0.001) and the frequency of having snacks increased as the frequency of eating out increased(p<0.01). The correlation between body image and physical variables in female subjects showed that CBI and IBI(p<0.001) had statistically significant correlation. Body weight showed statistically significant correlation with CBI(p<0.001), BMI(p<0.001) and height(p<0.001). The frequency of eating out increased as height(p<0.01) and the frequency of skipping meals(p<0.001) increased. When both male and female subjects wanted leaner body shapes, they preferred much leaner shapes despite their current body images belonging in the normal range. Additionally subjects preferred the body image in the normal range in cases when their current body images were lean. In particular, more female subjects had strong desires to become leaner in their body images than male subjects, which could be analyzed as a risk factor for physical him. From the above results, it is considered that both male and female subjects need to establish proper recognition and dietary behaviors for their body images and also need nutritional education and counseling for desirable weight control methods.
