This study was performed to investigate the nutrition knowledge, dietary attitudes, and dietary behaviors among high school students by gender. The subjects were 275 students (127 male, 148 female) in Incheon metropolitan area. Self-administered questionnaires consisted of general characteristics and anthropometric data, nutrition knowledge, dietary attitudes, and dietary behaviors. The average score of nutrition knowledge was significantly higher in female subjects (9.4) compared to male subjects (8.2) (p<0.01). Male subjects had a higher score for dietary attitudes than female subjects (p<0.001). Frequency of meals was significantly higher in male subjects compared to female subjects (p<0.05). Duration of meal time in male subjects was significantly higher ('5-10 minutes') compared to female subjects (p<0.001). Unbalanced diet was significantly higher in female subjects (66.3%) compared to male subjects (48.9%) (p<0.01). Male subjects showed significantly higher consumption frequency of 'dairy' (p<0.001) and 'beans' (p<0.001) compared to female subjects. For snack consumption, male subjects showed higher consumption frequency of 'nuts' (p<0.001), 'soda' (p<0.05), 'fast foods' (p<0.001), and 'ramyeon' (p<0.01), but lower consumption frequency of 'biscuits and bakery' (p<0.01) compared to female subjects. Therefore, it is necessary to develop a systemic nutrition education program for high school students by gender.

Purpose: Maternal knowledge, positive attitudes and interest toward breastfeeding may improve the sustainability of breastfeeding. This study examined the associations of knowledge, attitudes, and interest toward breastfeeding with the duration of breastfeeding in Korean mothers who used the internet. Methods: We conducted a cross-sectional study of 604 Korean mothers who breastfed their babies. Mothers were recruited through the internet and their knowledge, attitudes and interest toward breastfeeding were assessed using a web-based self-administered questionnaire. Geometric means and odds ratio (OR) with 95% confidence intervals were calculated. Results: Higher knowledge, attitudes, and interest toward breastfeeding were associated with longer duration of breastfeeding in Korean mothers. In particular, mothers who had optimal breastfeeding duration were more likely to be aware of the easiness of breast milk stimulation and breastfeeding, the development of attachment between mother and child, and pleasure from breastfeeding compared to those mothers with shorter duration. The association with optimal breastfeeding duration was more pronounced among mothers who graduated from high school for total attitude scores and total interest scores, compared to mothers who graduated from college or above. Conclusion: The results of this study suggest that it is important to improve maternal knowledge, attitudes, and interest toward breastfeeding in Korean mothers who use the internet as a source of knowledge. Also, the study results imply that the development of strategies to target mothers with relatively low education levels may improve breastfeeding rates.
This study was designed to compare the prevalence rate of obesity, food attitude, food frequency and food habits between children in Kangnung and Seoul areas. 1,005 children aged 9-12 were included in this study. They were composed of 343 children living in Kangnung from one elementary school, and 662 children in Seoul from two elementary schools. The body weight, height, waist and hip circumferences of children were measured and food frequency scores of Korean and Western foods were examined by questionnaire. And questionnaires about food attitude, food habits and life style were administered to the mother of each child. There was no significant difference in body weight and obesity index among three groups(one school of Kangnung area and two schools of Seoul area). The male children\`s prevalence rates of obesity in Kangnung and two schools(A, B) of Seoul were 10.3%, 10.3% and 7.3%, respectively. Female children\`s prevalence rate were 5.4%, 4.7%, and 6.3%, respectively. Children in Seoul turned out to more frequently eat such Korean foods like pulkogi, kalbi and fried rice and such western foods like butter, margarine, hamburger, pizza, and fried chicken. Children in Seoul had more tendency to eat regularly and spent less time in sleeping and watching TV and more time in exercise than the respondents in Kangnung. The obesity index of parents had a significantly positive correlation with that of children. These results suggest that children in Seoul have tendency to eat high-energy food frequently and to have more energy expenditure than children in Kangnung. In conclusion, further studies on the evaluation of energy intake and energy expenditure of obese and normal children different in area should be conducted. (Korean J Nutrition 34(1) : 198∼212, 2001)
The aim of this study was to investigate the effects of socio-demographic and health-related perceptions and twenty dietary behaviors on the superiority and preference, convenient use of and purchase motives of vegetables among 370 women(mean age 43.9) in Seoul and metropolitan and Gangwon area. Data was collected using a questionnaire developed in advanced studies. Almost all subjects rated vegetables more predominantly than grains or meats on the basis of health, diversity, and convenience to purchase. Recognition of healthly funcions of diet, purpose of diet and some dietary behaviors had influence on preference for vegetables. Those who recognized that diet had the function of disease control and prevention, knew the healthy options vegetables provide us, such as, preventing us from geriatric diseases, good sources of vitamins and minerals and considered other motives aside from health issues. From Pearsons's correlation analysis, it was revealed that sufficient time for meal preparation and pleasant eating and desirable life style and dietary attitudes, and a better understanding of nutrition were positively correlated with consumption of more vegetables and convenient use of vegetables. The subjects who recognized the ability of food to help prevent diseases, had a preference for vegetables and attitude to use nutritional knowledge and also considered the nutrition values of vegetables and environment friendliness. Everyday use of vegetables such as consuming a variety of different vegetables, a families favorite vegetables and variation of cooking methods had correlated positively with purchase motives. Therefore to encourage consumption of vegetables, it is important to notice three points continuously; first, practical information of nutritive values of vegetables, the contribution of vegetables in current animal protein foods centered diet and healthful functionalities. Second, the importance of regular diet and steadfast attitude and lifestyle. Finally, the quality of the market where the products are bought such as, quality control of freshness, sanitation, expression of producer and a pleasant environment to shop in.
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 purpose of this study was to investigate the nutrient intakes, nutritional knowledge, food habits, and lifestyle behaviors of moderately or severely obese children living in the Kyonggi-do area. The subjects in this study were 37 obese children with an obesity index higher than 130% in the forth to sixth grades of elementary school. Anthropometric measurements, 24-hour recall of dietary intakes, and a survey on nutritional knowledge, food habits, and lifestyles behavior were conducted in the 37 obese children (25 boys and 12 girls). The average age, body weight, BMI, and R$\ddot{o}$hrer Index were 12.4 years, 68.6 kg, $29.6kg/m^2$, and 194.9 in boys and 12.7 years, 65.7 kg, $29.8kg/m^2$, and 201.8 in girls, respectively. The percentage of correct answers on nutritional knowledge and nutritional attitude score/max score were 85.8% and 23.0/50 in boys and 87.0% and 17.5/50 in girls, respectively. Except for calcium (85.3%) in girls and calcium (62.7%) and folic acid (83.3%) in boys, the average daily nutrient intakes percentages of nutrients were greater than the DRIs values (107.9~327.3% in boys and 103.0~416.0% in girls). This study showed the existence of some problems associated with obesity, such as higher frequency of skipping breakfast, irregular meal times, unbalanced diet, lack of intake of some nutrients, low nutritional attitude, lack of physical activity, and time management in obese children. These results suggest that a systematic education program including nutritional education on balanced diet, good eating habits and behaviors, and importance of eating breakfast and meal regularity must be emphasized to improve nutrient intakes and food habits in obese children. Obese children also require a more concentrated program that includes physical activity, weight reduction, and weight maintenance strategies to improve their life habits.
The purpose of this study was to investigate sodium consumption and related psychosocial factors among hypertensive patients and normal adults through questionnaire development. The Theory of Planned Behavior provided the basis for the study. The mean blood pressure of subjects was 117. 1 mmHg/78.55mgHg in normal adults(N-218), 159.65mmHg/102.05mmHg(systolic/diastolic) in hypertensive group(N=219) and the sodium consumption was 5219.4${\pm}$1821.3mg in normal adults and 4631.4${\pm}$1749.1mg in hypertensive group. The results of Multiple logistic regression analysis showed that the odds of being hypetensive group were increasd as subjects felt that dalty food (OR=1.5) (OR=0.8). The odds of beign hypertensive group increased as subject received more support. With respect to perceived control, the odds of being hypertensive group were increased as subjects felt more confident in contolling salty intake when spouse likes to take salty food(OR=1.4). In contrast, subjects felt less confident in contolling sodium consumption when they took medicine(OR=0.8). Study findings revealed that all three factors, attitudes, subjective norms, and perceived control contributed to the model for explaining intentions, with subjective norms being most important. This findings provided the empirical evidence for the TPB in explaining salt intake. This study suggest that educational interventions for hypertension patients focus on changing sodium consumption through changing attitude toward high sodium consumption, subjective norms, perceived control over reducing sodium consumption of specific situations, specially subjective norms and perceived control. In addition, interventions may include strategies to change attitudes toward sodium consumption by helping hypertensive patients realize negative beliefs and modifying positive beliefs and to elicit and maintain subjective norm from doctors, family and neighbors, and to increase control beliefs for reducing sodium consumption.(Korean J Nutrition 33(8) : 833-839, 2000)
The purpose of this research was to analyze the job satisfaction and business attitudes of restaurant owners in order to explore solutions for improving restaurant management. The results were as follows : 1) The motive for starting a restaurant business was vocational aptitude \longrightarrow possibilities \longrightarrow good income : 2) In terms of job satisfaction, most respondents were satisfied with both the work itself and the income. It was also observed that the younger owners were more satisfied with their jobs than the older owners : 3) Increased costs, including labor and food costs, was indicated as the biggest problem in restaurant management. Respondents also perceived labor shortage as one of the most difficult problems. Men were more likely than women to consider the following problems as being more serious: rent, financial problems, taxes, regulation restrictions, menu development and customer complaints. It was found that as the size of the restaurants grew, the respondents perceived the shortage of labor as the hardest part of running a business : 4) Respondents agreed that employing good foodservice workers was the most important part of foodservice management. Owners also believed that they needed more research time for menu and service development 5) To be successful, the restaurant owners paid the most careful attention to food taste. Service, sanitation, and menu development were also emphasized. Respondents stressed the focus on service, good relationships, diligence, and faithfulness in order to be a good restaurant owner. The results of this research suggest that restaurant owners should have more professional conscientiousness to succeed in their own businesses, as well as improve the quality of the foodservice industry. Other important aspects related to the overall improved quality of the foodservice industry are: the continuation of government support, the enlargement of educational opportunities and greater respect for foodservice employees.

The purpose of this study was to determine the factors related to eating breakfast for middle and high school students in Seoul using the Theory of Planned Behavior. Out of 2,280 questionnaires distributed to 22 schools, 2,060 were returned (90.4% response rate) and 1,899 were analyzed (83.3% analysis rate). Gender, self-perceived household income level and mother's working status were examined as demographic factors. "Attitude", "Subjective norm", "Perceived difficulty in access to breakfast", "Perceived time restriction" and "Self restriction to breakfast" were extracted as psychosocial factors as the results of factor analysis and reliability test using 17 items. In case of middle school students, boys were more likely to skip breakfast than girls. The students perceiving their household income level "low or middle low" were more likely to skip breakfast than those who perceived their household income level "high or middle high". The students whose mother had a job tended to skip breakfast than those whose mother had no job. In case of high school students, the students perceiving their household income level "low or middle low" tended to skip breakfast than those perceiving their household income level "high or middle high". The results of analysis of variance, all the psychosocial factors examined in this study-"Attitude", "Subjective norm", "Perceived difficulty in access to breakfast", "Perceived time restriction" and "Self restriction to breakfast"- were related to the frequencies of eating breakfast during weekdays in both the middle and high school students.
The nutritional status of middle-aged overweight and control normal subjects were evaluated for the purpose of providing the background information of the degenerative disease control. A survey was conducted with 293 healthy subjects (121 males and 172 females) between the ages 40-64. The average BMI (body mass index) of male subjects was 24.5 $\pm2.75$, and that of females was 23.5 $\pm2.87$. The average values of WHR (waist-hip ratio) were 0.88 $\pm0.04$, for males and 0.82 $\pm0.07$, for females. The normal BMI group (BMI 18.5-22.9) comprised 28.9% of males and 47.1% of females. The percentage of overweight subjects (BMI 23-24.9) was 26.4% of males and 30.8% of females. The obese group (BMI > 25) was 44.6% of males ana 22.1% of females, showing the greater rate of obese state among male subjects. The average energy intakes were 76.6 $\pm14.9$% for males and 77.8 $\pm12.6$, % for females, protein intakes were 108.0 $\pm24.6$% for males and 111.2 $\pm22.7$, % for females of the RDA levels. The average intakes of other nutrients were above the 75% of RDA levels except calcium. The average nutrient intakes of the three subgroups according to their BMI values were not different for both males and females. There were weak correlations between obesity and blood biochemical indices. There were positive correlations between BMI or WHR and hemoglobin, hematocrit, fasting glucose, total cholesterol, triglyceride, AST or ALT. There were negative correlations between BMI or WHR and HDL-cholesterol. These results suggest that the obesity rate of middle-aged is an influential factor of chronic disease. The middle-aged subjects of this study with higher educational and socioeconomic background tend to have desirable nutrition knowledge and attitude, but the application of their knowledge or attitude was relatively poor.
