Along with the increasing interests of modem-day society toward topics of health and beauty, various studies are being actively conducted on the effects of diet for obesity prevention, and separate from aspects of disease prevention and health promotion. This study aimed to examine individual perceptions of obesity by age, and to prepare basic data for implementing an age-based weight control system, by comparing attitudes toward weight control. The research and analysis were conducted using questionnaires, provided to high school students(teenagers, 189 students), college students(20 or older, 116 students), and adults(30 or over, 88 adults) living in Daegu City. In terms of the respondents' perceptions of obesity, among those who described themselves as overweight, only about 10% were actually proven to be overweight. Also, significantly more female students than male students perceived themselves as overweight, despite the fact that they were in a normal weight range(p<0.007). There was no significant difference in the cause of obesity by gender, but it was found to be attributed to a lack of exercise for teenagers, and poor eating habits for those in their twenties and thirties. Concerning the intention to participate in a weight management class, the female teenagers showed significantly more interest than the male teenagers(p<0.017). Also, with regard to the respondents' attitudes toward weight control, the teenage females showed significantly higher interest in weight control than the teenage males p<0.003 and those in their twenties p<0.001. Moreover, regarding the period in which the respondents became most interested in weight, the teenage male students were most interested in weight during their middle school years and teenage females became most interested during their high school years. Therefore, the information from this study leads us to propose there is a need to correct the suggested reckless dieting that is occurring within an appearance-based society, as well as a need to establish a systematic weight control system, along with gathering subsequent basic data.

The study purpose was to examine weight control status and related factors among 370 high school girls in Seoul. Factors examined included interest toward weight control, body satisfaction, body image, beliefs regarding weight control and self-efficacy. $65.1\%$ had attempted to control weight and were categorized into attempt group. Those in the attempt group had higher body weight (p < 0.001) and BMI (p < 0.001) than the counterparts. They tried to control weight 2.9 times on average (22.4 days each time). The major information sources for weight control were internet ($62.8\%$), and TV/radio ($17.1\%$). Exercise was most commonly used for weight control, followed by reducing meal amount and skipping dinner. The attempt group was less satisfied with body size (p < 0.001) and perceived their body size as heavier than the counterparts (p < 0.001), but they showed more interest toward weight control (p < 0.001). The ideal body size of society or the body size that they want was very thin in both groups. Twelve out of 20 beliefs regarding weight control were significantly different between the two groups. The attempt group believed more strongly on the advantages such as increased self-confidence, appearance, attractiveness (p < 0.001) and 'good for making friends' (p < 0.01) In contrast, the attempt group believed less strongly about the disadvantages including harmful effects on health (p < 0.001), parents' dislike, feelings of discouragement (p < 0.01) and becoming (p < 0.05). The attempt group showed lower overall self-efficacy to control overeating (p < 0.05) than the counterparts. Especially, the attempt group felt less control of overeating in situations such as eating-out, after school, when they are with family (p < 0.01) or with friends, when they feel hungry, during examination periods and when others offer food (p < 0.05). This study suggested that weight management education for adolescents include strategies for changing body image and beliefs regarding weight control, as well as increasing self-efficacy to control overeating.

This study sought to determine family restaurant patrons' attitudes toward nutrition and healthy menus. A written questionnaire was handed out to 300 dine-in customers at the three different sites of T brand family restaurant. A total of 265 questionnaires were usable for data analysis, resulting in 88% response rate. Two attitude statements eliciting the strongest agreement were that 'Diet and chronic diseases risk are closely connected each other(4.44)' and 'Koreans are more nutrition & health conscious than they were in the past(4.41)'. The attitude statement-that nutrition is important when I eat out- received the lowest scores(2.92), which indicated that nutrition was not yet considered the most important factor when dining out. 23% of the respondents were interested in healthful foods, while 30% said they were unconcerned. Nutrition conscious group showed significantly (p<.000) higher attitude scores for most of statements than unconcerned group. Significant differences were found in age groups(p<.05, p<.01, p<.001), income levels(p<.05), educational levels(p<.05), health status groups(p<.05), and weight control interest groups(p<.05). Older respondents, respondents with higher income and educational levels were more interested in nutrition and healthy menus. Respondents who reported good health status and showed higher interest in weight control were more interested in nutrition and healthy menus. These findings indicate that restaurant firms should respond to consumers' increased interest in nutrition and healthy menus by offering healthful menus and increasing nutrition marketing activities. This may positively result in increasing customer counts and revenue as well as customer satisfaction level and brand image of restaurant firms. Moreover, restaurant firms are strongly encouraged to play an active role in promoting public's nutritional and health status because increasing consumption of meals away from home will seriously affect good health of our consumers.

Recently, the desire for low body weight, which is an abnormal weight construct along with obesity, has become an evident and serious problem in teenagers. In Korea, the desire for low weight is not perceived as an important problem, but it is rapidly expanding relative to the physical changes and developmental issues teenagers experience. The social atmosphere presented through mass media is the key influencer for the increasing low weight occurrence in teenagers. Because thoughts about beauty have changed among people, and since there is apparent blind interest in slim body shape and appearance, already low-weight individuals are attempting to lose weight along with obese persons. Thus, we consider it necessary to guide teenagers toward having correct perceptions with regard to weight and their own body shape, and that a healthy and appropriate weight is beautiful. Therefore, for this study, we investigated body perception, abnormal weight, attitude toward weight control, and factors related to eating behavior among teenage girls, who are considered the at risk group for overt body weight control behavior. Based on this, we have attempted to set in motion a systematic and active nutrition education program that will allow us to increase body satisfaction by educating on nutritional issues related to development, and ultimately, implant healthy body shape perceptions.

This study was designed to examine weight control, nutritional knowledge, dietary attitudes and eating behaviors of 370 high school girls and to investigate if there were differences in these variables by weight control status. The weight control attempters (65.1%) had significantly higher body weight and BMI (p<0.001). The difference between desired and current body weight was -9.1 kg in the attempters, showing a significantly higher difference than the counterparts (p<0.001). The attempters also showed more interest toward weight control (p<0.001), but were less satisfied with their body size (p<0.001). Most of subjects (88.1%), especially in the attempters (96.7%) responded that they would try to control their weights in the future. The regular exerciser was 22.9% in the attempters while the percentage of the counterparts was 11.9% (p<0.05). The use of internet or television watching was not significantly different by weight control status. Subjects scored 15.8 out of 20 on a nutritional knowledge scale, which showed a moderate level of knowledge. The nutritional knowledge score was 15.7 for the attempters and 15.8 for the counterparts. None of the nutritional knowledge items reached statistical significance, although the percentages of correct answers regarding weight control or balanced meals were slightly lower in the attempters. The attempters showed more favorable eating attitudes than the counterparts (p<0.001), especially in the attitudes of applying nutritional knowledge to daily life (p<0.01), attitudes for modifying diets (p<0.01) and importance of having adequate meals (p<0.01). The eating behavior was moderate, with mean scores of 31.1 (possible score: 15 - 45). Subjects showed problems in eating a variety of foods, eating meals regularly, eating slowly, eating breakfast and consumption of some food groups (e.g., dairy foods, fruits). The attempters consumed seaweeds more frequently than the counterparts (p<0.05). Although there were not many significant differences by weight control status, this study suggested that nutrition education for adolescent girls should be planned to provide nutrition information regarding desirable weight control as well as modifying diets and eating behaviors.

The purpose of this study was to implement and evaluate the nutrition education program for elementary school children Subjects were 5th graders (n = 142) of an elementary school in Seoul, and 138 children completed four sessions of nutrition education during March-April, 2008. One group pretest-posttest design was used to evaluate the program effectiveness. Anthropometric measurements and measurements on nutrition knowledge, eating attitudes and eating behavior were done before and after education. Data were analyzed using paired t-test, t-test and ${\chi}^2-test$. After completing nutrition education, body mass index (from 19.3 to 18.9), fat mass (from 10.9 kg to 10.1 kg), percent body fat (from 25% to 23.3%) of subjects decreased significantly (p < 0.001). Percentages of overweight or obese children were 24.6% at pretest and decreased to 20.3% at posttest, although it did not reach statistical significance. Total score of nutrition knowledge increased significantly from 11.9 (59.5/100) at pretest to 14.7 (73.5/100) at posttest (p < 0.001). After nutrition education, percentages of correct answers increased significantly in 10 knowledge items out of 20 items. These included items such as desirable weight control, energy requirements for boys, food groups, snack, and function of fat and balanced meals (p < 0.001). Total score of eating attitudes increased significantly from 35.1 to 36.9 (p < 0.001). Attitude of applying nutrition knowledge to daily life (p < 0.001), interest toward nutrition and health (p < 0.001), attitude of moderating food intake (p < 0.01), and attitude toward eating habit and future health (p < 0.05) were significantly different between pretest and posttest. Total score of eating behaviors increased significantly from 46.7 (possible score: 20-60) to 49.5 by nutrition education (p < 0.001). Improvement in eight eating behaviors were noticed after nutrition education. These included eating meals slowly, eat protein foods (p < 0.001), eating breakfast, eating meals regularly, eating meals with diverse foods, having dairy foods, eating foods using plant oils (p < 0.01), and having grains (p < 0.05). Subjects evaluated quite positively in attractiveness of program, understanding of program contents, helpfulness of program in improving nutrition knowledge and meal management. Study results show that the nutrition education program was effective in improving nutrition knowledge, eating attitudes and changing eating behaviors of children. This program can be used in nutrition education of children at school or at public health centers.
