The purpose of this study was to investigate the factors influencing body mass index of 618 university students located in the Gwangju area, from Nov. 20th to 30th, 2002. The subjects included 301 males(48.7%) and 317 females(51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index(BMI) was 3.7, 88.0 and 8.3 for the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time(65.1%) of the cases. Self-reported eating habit problems were eating irregular meal(52.4%), overeating(21%), prejudiced meal(12.4%) and skipping meal(7.4%). The type of favorite snack was biscuit(31.9%) and cup Ramyon(31.9%). The type of favorite beverage was juice(23.3%). The coffee intake was higher in males compared to females. The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 2.8% respectively. Percentages of weight control experience were 30.2 and 51.4 in the male and female, respectively. The BMI of students living in home and eating breakfast was higher than that of the other students. The BMI of students eating cup Ramyon and water increased. The BMI of students taking regular exercise and weight control tended to be higher than that of subjects not doing so. When the amount of pocket money available and the rates of coffee intake, alchol drinking and smoking increased, the BMI was increased. Therefore, nutritional education for university students is needed so as to improve their health and to modify life habits and nutritional education program should be developed to meet the various needs of these students.

This study was performed investigate eating behaviors and their association with obesity in Korean elderly people. A total of 9,408 (male 4,487, female 4,921) Korean adults aged 40 to 69 years were interviewed and examined from May 2001 to Feb 2002. The subjects were classified into 4 weight status groups based on body mass index (BMI, $kg/m^2$): under weight, BMI<18.5; normal, $18.5{\leq}BMI\leq24.9$; overweight, $25.0{\leq}BMI\leq29.9$; obesity, $BMI\geq30.0$. Anthropocentric parameters, eating behavior, and preference of cooking method and taste were examined. In male, distribution of weight status by BMI was under weight 2.4%, normal 58.1%, over weight 36.7%, obesity 2.8%. As the BMI increased, the rate of skipping meal, snacks, and eating out were increased and the rate of eat alone was decreased. When compared according to the weight status by BMI, the frequency of the steamed, roasted, fried, seasoned, and soup intake rates were increases in the cooking methods and preference of greasy taste was increased by degree of obesity. In female, distribution of weight status by BMI was under weight 1.4%, normal 52.8%, over weight 38.6%, obesity 7.2%. There were differences in the rate of eating out, snacks, the frequency of fried food intake rates, and preferences of salty, hot, greasy taste according to the weight groups by BMI. In this results, we suggests that keep regular meal and keep away from the high-fat, salty, stimulative foods for prevent and administer the obesity in Korean adults meal and female.

This Study was carried out to find out regional differences about dietary life and factors associated with meal of school children and adolescents between urban and rural area. Forty students from each of the nationwide 51 schools of three different levels(elementary, middle and high school) were surveyed by self-developed questionnaires. Total of 1,886 questionnaires (1,243 from urban and 681 from rural) were collected and distribution of subjects was 544 from elementary school, 661 from middle school, and 681 from high school. The results were summarized as follows. BMI and degree of satisfaction on body weight of elementary and middle school subjects were not significantly different between urban and rural area. But there were significant regional differences in $BMI(urban\;21.2{\pm}3.0,\;rural\;20.5{\pm}2.8,\;p<0.05)$ and degree of satisfaction on body weight of high school subjects(p<0.001). Elementary(p<0.01) and middle school(p<0.05) subjects in urban area had exercised more frequently than those in rural area. Regularity of having breakfast was not significantly different between urban and rural area at each of three different levels of school. Most subjects(urban 92.2%, rural 92.1%) had lunch regularly by virtue of school lunch service. Regularity of having dinner of elementary(p<0.01) and high school subjects (p<0.01) was significantly different between urban and rural area. Reason for skipping dinner of high school subjects was significantly different between urban and rural area (p<0.05). The most delicious meal was dinner for 51.8% of the urban high school subjects and lunch for 51.7% of the rural subjects. Only one third had intention of participating in school breakfast program regardless of region and levels of school. The findings suggested that nutrition education programs for school children and adolescents include different strategy according to region and levels of schools.

The purpose of this study was to investigate weight gain during pregnancy based on pre-pregnant Body Mass Index, to compare eating habits based on the recommended standards for weight gain presented by the Institute of Medicine, and to identify factors affecting the weight gain of pregnant women. The subjects were grouped into three categories according to the recommended weight gain standards presented by the Institute of Medicine: the inadequate group, the adequate group and the excessive group. The excessive group had a significantly higher pre-pregnant Body Mass Index than that of the two other groups. Based on a comparison of the eating habits and nutrient intake of the women to the recommended standards for weight gain, the excessive gain group had large meals and ate more frequently outside of the home when compared to the pre-pregnancy period. Based on an analysis of correlations between weight gain during pregnancy and diet factors, the adequate gain group had positive correlation between weight gain and a "balanced meal" and had negative correlation with "convenience meals". The excessive gain group had a positive correlation with "convenience meals" and had a negative correlation with "meal skipping." All the pregnant women were more frequent in the "overeating categories" and all ate more "fruit," as their weight gain was higher. In particular, the excessive gain group was frequently evaluated as "overeating". These results indicate that the factors affecting weight gain during pregnancy were the Body Mass Index before pregnancy, eating types, and eating habits. As the Body Mass Index before pregnancy was higher, the ingestion of a 'balanced meal' was less, and overeating and gluttony were more frequent. Therefore weight gain was enhanced.

The purpose of this study was to investigate the dietary habits and snack consumption behaviors of middle school students with different obesity indexes in the Chungnam area. The survey was carried out using self-questionnaires and included 385 students(119 underweight, 193 normal weight, 66 overweight). The rate of skipping meals was higher for underweight students than overweight students; however, this difference was not statistically significant. The mean time of meal was 10 to 20 minutes and the criteria for choosing to eat a meal were 'hunger' and 'taste' in all groups. More than half of the subjects ate snacks 1 time a day, which were purchased outside. The typical snack time was 'between lunch and dinner'. The criteria of for consuming a meal were 'taste' and 'price' in all groups. In the underweight group, the snack food scores were ice cream(4.4), fruit(4.3), fried chicken(4.1), sports beverage(4.0), fruit juice(4.0), pizza(4.0) and, tteokbokki(3.9). In the normal weight group, the snack food scores were ice cream(4.3), fried chicken(4.2), pizza(4.0), sports beverage(3.9), fruit juice(3.9) and, tteokbokki(3.9) in the overweight group, the snack food scores were ice cream(4.3), fruit(4.3), fried chicken(4.2), yogurt(4.0), sports beverage(4.0), fruit juice(4.0) and, ramen(4.0). In conclusion, the snaking behaviors of the subjects were not significantly different based on their obesity index. However, this study may provide basic information on the snacking behaviors of middle school students, and the findings suggest that nutrition education or counseling can improve snack intake habits and positive behaviors toward healthy adolescents diets.

This study was conducted to develop the standard breakfast menu for those weak groups having insufficient breakfast intake. The following three target groups are classified as: 16-19 years old high school male student, 20-29 years old female who have job or college students, 20-29 years old male or female who have job (double income family). While developing menus for each target groups, we applied several basic guidelines for meal planning as follows: Nutrient intake level was set to $\graction one-Third$ of RDA, while the energy level to $\fraction one-quarter $ of RDAs. Most Sequent meal pattern of Koreans was adapted; Suitabilities of appropriate serving size and cost for middle-income families were considered; Domestic foods and ingredients were used. We developed 24 menus summed by 2 menus for each season and three target groups. When evaluating the menus, most of the breakfast menus were sufficient of nutrients as a meal for the subjects. Three food groups such as grain/starch group, meat/fish/egg/bean group, vegetable/fruit group were included in all menus. Even though milk/dairy products group was not excluded for some menus, other calcium substitutes like anchovies were used. Oil/nut/sugar group was used to a minimum. The average number of foods for each menu was 12.8, which ranged from 10 to 17 depending on the menus. The average weight of the menus including soup was 822 g, 633 g and 730 g for each target group, respectively. The average price of the menu ranged from 2,000 to 3,500 won per person. The above results could be applied at home as well as foodservice institutes and furthermore could offer information for developing breakfast-substituting food products.

This study was undertaken to analyze the growth, nutritional, and dietary risk factors of elementary school students belonging to the Busan Metropolitan City Office of Education and provide the basic data needed to develop an underweight and obesity prevention program. In 2021, BMI and Dietary Screening Test (DST) data of 4,046 children surveyed by the Nutrition Education Experience Center's "Diagnosis System" of the Busan Regional Office of Education were analyzed. The DST consists of 36 questions about lifestyle habits, meal quality, meal regularity, snack quality, and eating behavior. Of the children included, 6.8% were underweight, 65.4% were normal weight, 13.4% were overweight, and 14.4% were obese. Children in the obesity group had shorter sleep and meal times (P<0.001), lower vegetable and fruit consumption frequencies (P<0.001), higher fast food consumption frequencies (P<0.001), higher rates of skipping meals (P<0.01) and breakfast (P<0.001), and more frequently used smartphones and watched TV during meals (P<0.001). The underweight group had the highest scores for all eating development factors but more frequently had chewing and swallowing difficulties (P<0.001). The study confirms underweightedness and obesity are present different problems and indicates that nutrition teachers should conduct accurate studies on the eating habits and behaviors of obese and underweight students and provide individually tailored nutritional counseling.

This study was aimed at comparing the dietary pattern of middle school girls according to family type. As for subjects, sixty girls of M middle school of Taejon city were chosen as a total. They were devided into two groups consisted of thirty subjects respectively ; those who live in single mother's family(SMF) and both parent's family(BPF). In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day dietary records and questionnaire. The results obtained in this study were as follows : 1) Mean daily intake of all nuitrients except calcium were more than RDAs in two groups. However, intake of calcium and rtio of Ca / P were lower than RDAs in two groups. And proportion of less than 2/3 of RDAs of calcium were higher than other nutrients. Intake of iron was more than RDAs, but nutritional status of iron might be poorer considering the food sorce of iron taken by subjects. According to family type, girls of SMF seemed to have more serious to have more serious problem in these nutrients than those of BPF. 2) The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 25.2, 31.3, 24.6 and 18.9 in SMF, and 19.7, 33.1, 24.3 and 22.9 in BPF. Thus it proved that lunch contributed more energy intake than any other meal, and that snack was an important means to supply nutrients for girls of two groups. And energy intake through breakfast of SMF was more than BPF. 3) The major dietary problems of two groups were unbalanced diet, missing meal, and overeating. The degree of sharing meal with family was lower in girls of SMF than those of BPF. The degrees of skipping (p<0.05), or irregularity, or preparing meal by girls(P<0.05) in the case of dinner were tended to be more frequent in SMF than BPF. And number of food taken per day was less various in SMF of 15.2 kinds than BPF of 17.1 kinds(P<0.001). As a conclusion, subjects should take more calcium or iron contained food which is well absorved, and eat diverse foods to improve their nutritional status. And it is also necessary that calorie intake through snack should be diminished, and dinner should be eaten regularly and shared with family if possible. In view of family type, girls of SMF proved to have poorer food habit than those of BPF. Thus, these results shows that dietary pattern of girls is different atcording to family type. Therefore, we should carry out nutritional education for girls considering the difference of dietary pattern by family type. In addition, nutritional education for girls of SMF should be regarded more importantly than those of BPF because girls of SMF might have more chance to manage their meal by themselves and also have more dietary problems.

Objectives: The purpose of this study was to investigate the eating behavior toward processed foods among college students who live in different types of residence. Methods: This is a cross-sectional study targeting a total of 476 college students living at home with their family, living in a rental house with self-boarding, living in a lodging house, and living in a dormitory. Eating behaviors, including preference and the frequency of processed food intake were surveyed and compared according to the type of residence. Results: The rate of skipping a meal was significantly higher among students who reported self-boarding than those living in other types of residences. The main reason for skipping meals was that they got up late. In the entire study population, the main reason for consuming processed food was easy-to-cook (33.8%) and the primary consideration for choosing processed food was the price (54.0%). The processed food the most favored by college students was the processed noodles; those living at home with their family or living in a dormitory preferred milk products; those living in a rental house with self-boarding or in a lodging house preferred confectionery, retort pouch, convenience food, and canned/bottled food. The frequency of processed food intake was significantly higher in the students who reported self-boarding than those living in other types of residences (p < 0.001). Conclusions: Students' preference toward processed foods differed according to their type of residence. The frequency of processed food intake was significantly higher in students who reported self-boarding indicating that the type of residence of student is associated with their choices and consumption of processed foods.

A rapid increase in urbanization and industrialization brings about a change in economic status which results in considerable changes in lifestyle including food habits and disease and mortality patterns. The purpose of the present study was to investigate recent food habit changes if any, reasons for food habit change, current food consumption patterns, and breakfast practices among urban adults with middle and upper income levels. Three hundred men and women, aged 20-60 years, were randomly selected and interviewed individually by trained interviewers. Among the twenty food groups studied, subjects reported that, compared to two years ago, they are now eating more fast foods, meats, fish, vegetables and fruits, and less rice, noodles, pastries, and salt. The changes in fast foods, fruits, and rice consumption patterns varied significantly between age, sex, income level, and BMI groups. The two most primary reasons for food habit changes were 'for my own health' and 'for my family's health', which shows that health seems to be the major concern in changing food habits. Among meals, the breakfast meal was rated as the most important one, and was not affected by the sociodemographic variables. However, the average rate of skipping breakfast was found to be as high as 33% with a greater rate in younger age groups. The rats of breakfast skipping was found to vary between different income, education, and BMI groups. Among the subjects who eat breakfast meals daily, a traditional Korean breakfast of rice and soup was found to be still a predominant choice, although younger age groups, upper income groups, and people with more education choice, although younger age groups, upper income groups, and people with more education tended to eat a western-style breakfast more frequently. These findings are applicable at the planning and implementation stages of various nutritional improvement projects as a part of the National health Promotion Law.
