This survey was conducted from June 2004 to August 2004, through questionnaires given to 432 women aged ranging from 20 to 50 years, who were living in the Seoul metropolitan area. The questionnaires were designed to determine the physique, level of obesity and dieting survey as well as to uncover which diets were in fashion and their satisfaction degree. Dieting-related knowledge and dieting side effects were also investigated. The results were as follows: In dieting survey, as the age increased, dieting for health reason (52.3%) increased, whereas that for aesthetic reasons (32.6%) decreased (p<0.05). The most effective methods of dieting were exercise (50.2%) and diet (45.0%) regimens. In regards to exercise frequency, 46.5% for none, 23.5% for 1-2 times a week, suggesting that most respondents do not practice exercise for dieting purposes (p<0.05). Major source for dieting was shown to be obtained from relative family or friends (31.7%), newspapers or magazines (29.3%) and internet (14.9%). As the age decreased, information from the latter increased, whereas that from TV program (21.2%) decreased (p<0.05). Reasons for excess weight were bad eating habits (39.6%), lack of exercise (38.3%), pregnancy and childbirth (10.6%). In fad dieting, while organic foods and aerobic exercises scored the highest satisfaction degree among diet and exercise regimens, on the other hand, sauna, steam baths and high temperature half-immersion baths scored the highest among surgery and other special therapies. As the age increased, the satisfaction degree for organic foods such as organic vegetable and high functional boiled cooked rice increased (p<0.05). As the age increased, scores on dieting-related knowledge decreased. Side effects of dieting included dizziness 06.2%) fatigue (15.1%) indigestion/constipation (11.1%) physical weakness 00.5%), loss of concentration (7.8%), dry skin (7.4%) loss of motivation (6.7%). The above results showed that attitude toward dieting among adult women varied with age and in light of the well-being trend, organic foods and aerobic exercises scored the highest satisfaction degree through all age.

Older people have increased interest and involvement in controlling their aging body through physical exercise and dieting. This study examined the relationship between body image and the participation of older people in exercise and dieting. Two measures of body image (appearance attitude and appearance orientation) were used to study their relationships to participation in exercise and dieting among older people. Data were collected via a mail survey of older married couples residing in three U.S. metropolitan areas of Florida. A total of 94 couples who were 60 years older participated in this study. Multiple regression was run separately for men and women. The results indicated that for both men and women, appearance attitude was inversely related to dieting and positively related with exercise (even though the relationship with exercise was weak for men). Appearance orientation was not significantly related to exercise or dieting for both men and women. A new scale development on body image for an aging population was suggested. Various activities performed by aging people to manage their aging body and appearance need to be studied as related to physical and psychological well-being that includes body image.

Dieting behaviors prevail among most women and are highly increasing among female adolescents who don't have to lose weight. The dieting behaviors of normal or low weight groups are highly related to the negative impact of health risk behaviors. We need a strategy for intervening in the dieting behaviors of relevant groups. With this background, a study was conducted to examine the current situation of dieting behaviors and related factors in middle school girls, and to provide guidelines for the relevant dieting group. This survey was carried out by self-questionnaires passed out to 901 middle school girls from 3 middle schools in Seoul. Data were collected from April 10th, 2000 to April 17th, 2000 and 794 respondents' data were finally selected for analysis. The instruments of this study were Shin's scale for effects of mass-media, Birleson's depression self-rating scale translated by shim, Rosenberg's self-esteem scale, Smilkstein's Family APGAR score translated by Yoon, Kim's school-related adjustment scale. The credibility of instruments was 0.41~0.83 in the pilot study and 0.70~0.86 in the main study. The summary of results was as follows: 1. The general characteristics of respondents were analyzed. In comparison of grade and dieting behaviors, the subjects of the group perceived that their body image was obeser than their real body image and their ideal body image was slenderer than their current body image. A dieter's body image was seriously distorted. 2. The dieting behaviors were analyzed. The Subjects' BMI was within the normal to low range -- they didn't have to lose weight. But actually 47.3% of the respondents were dieters. Their main dieting methods were exercise(71.8%), computer games(64.9%) such as DDR and pump, and intake reduction(64.1%). Most dieters were using desirable methods such as exercise and intake control. But unhealthy methods such as saunax, smoking and harmful drug-use were also used by a few dieters. The main reason for dieting was attractiveness. The chief resources of dieting methods were mass-media(67.8%), friends(64.3%), and parents & relatives(35.1%). Only a few subjects obtained the information from health professionals. While they were trying to lose weight, 42.1% of the subjects experienced side effects such as dizziness(45.0%), apathy(20.5%), appetite loss(18.5%), amenorrhea and the irregularity of the menstrual cycle(16.6%). 3. The relationship between dieting behaviors and factors was analyzed. Dieting behaviors were significantly related to the experience of menarche, the experience of dating with heterosexuals, perceived body image, self-esteem, depression, family's relationship, school instruction-related adjustment, school life-related adjustment, and the effect of mass-media. After that, the multiple logistic regression was used. The analysis revealed that dating, perceived body image, the experience of menarche and the effect of mass media were significant factors. In conclusion, strategies for preventing irrelevant dieting behaviors are urgently required to enhance female adolescents' ability to choose the right information from countless others and to recognize their optimum body image.

A cross-sectional survey was used to investigate the rates of overweight and obesity (BMI$\geq$25), and eating attitudes among college students. Data were collected at a large southeastern university. Adolescents (ages 18-25) self-reported weight and height (to calculate BMI), and, in addition to demographic information, completed the eating attitudes (EAT 26) scale to assess dieting tendencies. Significance of the mean BMI differences between gender and ethnic background were assessed by one-way analysis of variance (one-way ANOVA). Chi-square was used to determine whether the rate of those with BMI$\geq$25 between gender and ethnic background was statistically significant. While 52.7% of the students' BMI were within the normal weight category, 15.2% were underweight, 21.3% were overweight, and 10.8% were obese. The rate of BMI$\geq$25 differed by gender and ethnicity, with males and African Americans having higher rates. About 12 % of the participants reported disturbed eating behavior, which is lower than previously reported. Even so, results support the generally held belief that disturbed eating attitudes and unhealthy dieting are common among college students, especially among females. At the same time, disturbed eating attitudes are not just the domain of young female students; about 10% of college males reported disturbed eating attitudes. Findings of this study call for obesity prevention/intervention and lifestyle modification outreach programs among college students. Weight status and unhealthy eating behaviors of college. students should be a concern to health care professionals. While obese young adults will likely remain obese throughout their adult life, excessive dieting among students, which is linked to eating disorders and other health hazards, does not provide healthy and adequate alternatives for maintaining a normal BMI. Implications for obesity prevention programs are discussed.

BACKGROUND/OBJECTIVES: The obese population is rapidly increasing because of reduced physical activity and a Westernized diet; consequently, various chronic diseases are more prevalent. With the increasing interest in body shape and appearance, research on body shape perceptions and accompanying weight control behaviors are needed for healthy weight management. SUBJECTS/METHODS: A cross-sectional survey was conducted on randomly selected 536 (209 men and 327 women) aged 20 to 65 years. Body mass index (BMI), body-shape perception, weight control behavior, quality of sleep, and place of residence were collected using self-reported questionnaires. Multivariable logistic regression analysis was conducted using complex design in each groups. Collected data were analyzed using the SAS 9.4 statistical package, and the significance level was set at P < 0.05. RESULTS: When these two variables were divided into four groups, they were found to influence dieting attempts. People with abnormal weights who were dissatisfied with their body shapes attempted dieting 5.23 times more than those with healthy weights and satisfaction with their body shapes. Further, those with normal weights but dissatisfaction with their bodies attempted dieting 4.45 times more than those who were satisfied with their shapes. Subjects in their 20s attempted dieting 2.53 times more than those in their 30s and 40s, and female subjects attempted dieting 2.24 times more than male subjects. CONCLUSIONS: A correct perception of one's shape can be an important factor for dietary behavior, as body shape perceptions and dieting attempts are strongly related. Additionally, healthy weight management and nutrition education are important elements to incorporate into a weight control program aimed at preventing excessive weight control behaviors and promoting correct perceptions of body shape.

Recently, the number of obese people have been increasing due to westernized diets and increased sedentary activity. In particular, obese adolescent have been newly recognized as having significant health problems. This study focuses on determining the gender difference of obese adolescents through implementation of a structured questionnaire on general characteristics, attitudes toward dieting, eating habits and emotional depression due to obesity. Data collection was carried out by 291 students in attendance at 3 high schools in Pusan from 11. 2. 1998 to 11. 30. 1998. The targets were 148 boys and 143 girls who were judged as obese in the school's physical check-up. The test of reliability of this research was calculated by chronbach's α. Data analysis was managed by computer and statistics by SPSS/WIN. The results of the survey are as follows: 1. For the questionnaire regarding attitudes toward dieting which include 28 items, 10 out of 28 items (about 36%)showed gender difference. 2. For the questionnaire regarding eating habits which include 17 items, 5 out of 17 items (about 30%)showed gender difference. 3.For the questionnaire regarding emotional depression about obesity, 30.6% of boys and 27.3% girls answered but no statistical significance. The results of this survey indicated that this study will be important as a good guideline for treating obese adolescents. It is hoped that much more research on gender difference in obese adolescents will be implemented in the future. In addition, the development of effective treatments for obesity should be based on the gender of the adolescent.

BACKGROUND/OBJECTIVES: There is little information on the association between weight misperception and eating behavior in Korean adolescents. Therefore, we investigated the association of food intake habits and dieting method and disturbed eating behavior (DEB) in relation to weight misperception. SUBJECTS/METHODS: Data was collected by using a nationwide online panel survey from 6,943 adolescents enrolled in middle/high school. DEB was measured with the Eating Attitudes Test (EAT-26) and those who scored ${\geq}20$ on the EAT-26 were considered to have eating disorder. Logistic regressions were conducted to examine the association between weight misperception based on self-reported weight status and dieting method and eating behaviors. RESULTS: The proportion of weight underestimation was 23.5% and that of overestimation was 24.0%. Weight overestimating girls were more likely to engage in various unhealthy dieting practices (OR = 1.69 for fasting; OR = 1.88 for laxative or diuretic use; OR = 2.05 for self-induced vomiting after meals; P < 0.05). Moreover, there was a strong association between overestimation and undesirable eating behaviors, especially among girls, e.g.: having breakfast (OR = 0.85), high consumption of fast foods (OR = 1.28) and regular sodas (OR = 1.39), but not among boys. In both genders, weight overestimation appears to be a major risk factor for DEB (OR = 1.34 for boys and OR = 1.41 for girls; P < 0.05). CONSLUSIONS: Weight overestimation is associated with unhealthy weight control practices and eating behaviors. We particularly found a significant association between weight overestimation and DEB among nationwide Korean adolescents.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

The aim of this study is to explore diverse characteristics of females aged 25 to 49 years grouped according to Body Mass Index(BMI), and to investigate the effect of body satisfaction and self-esteem on involvement in dieting within each BMI group. In total, 549 females who participated in an online survey were divided into groups based on BMI(underweight, normal, and overweight). Results demonstrated three key factors, as follows. First, differences were identified among BMI groups according to demographic characteristics(age, household income, and marital status), although no difference according to education level was found. Second, differences according to BMI groups were found in body satisfaction and involvement in dieting, whereas were not found in self-esteem. Third, model testing for each BMI group showed, a positive correlation between body satisfaction and self-esteem in all three groups. However, there was a difference in causal relationships among variable across BMI groups. Body satisfaction negatively affected and self-esteem positively affected involvement in dieting for the underweight and normal groups, whereas there was no causal relationship between variables in the overweight group. Based on these results, basic information of groups segmented by the level of BMI was obtained, which could be used for both academic and practical implications.

The study was designed to investigate the relationship between dietary intakes and the obesity of 400 students who were the third grade in middle school in some areas of Seoul. The survey conducted from March 3 to 13 , 1993. The results obtained were summarized as follows :The average height and weight of surveyed subject were similar to that of standard ( the third grade students in middle school in Seoul, 1991) . Compared to the standard weight/height ratio, subject who belonged to overweight and obese group were 16.4% of male students, 16.1% of female students respectively. Female subjects showed higher ratio than male subjects in skipping meals, frequency of snack per day and concern about a dieting . In case of subjects who belonged to weight /height ratio was high, their speed of dining was fast and they have more concern about a dieting. Compared to the amount of the nutritional intakes of RDA, calcium intakes of male and female subjects were deficient. Especially iron intakes of female subjects were deficient. In takes of Calorie (p<0.01) protein(p<0.05) and fat 9p<0.01) of obese group were higher those of non-obese group. Obese group showed good appetite and overeating also . Correlation analysis showed that obese group seemed to the closely associated with relative body weight of parents, family income, frequency of meals per day, frequency of meals per day, frequency of snack per day, speed of dining and overeating .
