The purpose of this study was to investigate the effect of bone mineral density on life styles, dietary habits and nutrient intakes among the male college students. The subjects were divided into four groups; $Q_1$ (calcaneus BMD < 25 percentile, n = 117), $Q_2$ (25 percentile $\le$ calcaneus BMD < 50 percentile, n = 118), $Q_3$ (50 percentile $\le$ calcaneus BMD < 75 percentile, n = 118) $Q_4$ (calcaneus BMD $\ge$ 75 percentile, n = 116). And they were asked about general characteristics, life style, dietary habit, and nutrient intake using questionnaire and 24-hr recall method. They were measured the bone mineral density of calcaneus using quantitative ultrasound. The average age of the subjects of the study was 23.0 yews and the average height, weight, and BMI were 174.7 cm, 69.0 kg, $22.5 kg/m^2$. The bone mineral density in calcaneus was $0.43 g/cm^2$ in $Q_1,\;0.50 g/cm^2$ in $Q_2,\;0.56 g/cm^2$ in $Q_3$, and $0.69 g/cm^2$ in $Q_4$ (p < 0.001). The results showed that $Q_1$ tended to have irregular exercise compared to the other three groups. Compared with $Q_1$ and $Q_2$, the frequency of skipping breakfast was lower in $Q_3$ and $Q_4$. Also the results showed that the $Q_4$ was significantly more often to drink coffee compared with the other three groups (p < 0.01). The mean daily energy intake was 2210.6 kcal ($88.4\%$ of RDA). The intake of energy, vitamin $B_2$, calcium, and zinc did not meet the Korean RDA. Also the $Q_2$consumed significantly lower intakes of protein (p < 0.05) and plant protein (p < 0.05) compared to the $Q_3$ and $Q_4$. The $Q_1$ and $Q_2$ consumed significantly lower intakes of vitamin $B_2$ (p < 0.01) compared to the $Q_3$ and $Q_4$. In conclusion, male student in lower bone mineral density appeared to have unhealthy life styles and dietary habits in terms of irregular exercise, high frequency of skipping breakfast and lower intakes of protein, vitamin $B_2$ showing a strong need proper education on meal practices and exercise habits for the bone health.

The purpose of this study was to compare weight control behaviour, eating habits and health-related life habits according to the obesity degree by body fat percentage (%Fat) among middle-aged women. The subjects were 170 middle-aged women who lived Gunsan City, and they were assigned to one of the following groups based on their %Fat; normal weight group (18% - < 28%), overweight group (28% - < 33%) and obesity group (over 33%). The height, body weight, %Fat, the circumference of waist and hip of them were measured. Eating habits and health-related life habits were evaluated based on questionnaires. The results were as follows. Their weight, %Fat, body mass index (BMI), relative body weight (RBW), waist, hip, and waist-hip ratio (WHR) were significantly higher in the obesity subjects when compared to the normal and overweight subjects. Self-perception for weight (p < 0.001), desire for weight control (p < 0.01), and reasons of weight control (p < 0.05) were different among three groups. The main skipped meal was breakfast (67.9%), reasons of skipping meals were different among three groups (p < 0.05), and main reasons were "lose one's appetite" and "have not enough time". Food habits score for each food was not significantly different among three groups, but eating the meal on thinking with food combination in normal group was higher than overweight and obesity group (p < 0.01). Correlation coefficients of food habits score and anthropometric measurements were that salty of food was negative and food habits scores were positive correlation for anthropometric measurements and obesity index (p < 0.05 - p < 0.001). Frequency of exercise and fitting exercise for body were different among three groups (p < 0.05). Obesity group was lower frequency of exercise than the other groups. Regular diet was positive correlation with food combination (p < 0.01), taking fish (p < 0.05), taking vegetables (p < 0.01), taking bean products (p < 0.01) and food habits score (p < 0.01), frequency of eating out and snacks were negative correlation with taking fruits and fishes. Therefore, proper nutritional education for middle-aged women in obesity group is recommended regular diet, good food habits and exercise. The middle-aged women must decrease the frequency of eating out, snack and the salty foods, and increase the fruits and vegetables. They must have healthy life styles for exercise, smoking, and drinking.

The purpose of this study was to examine food habits and dietary behavior related to using processed food among male college students residing in dormitory and self-boarding in Gangwon. A total of 344 students (dormitory group: 227, self-boarding group: 117) were surveyed from May to June of 2012. The results are summarized as follows: self-boarding group had a significantly higher frequency of skipping breakfast and lunch and frequency of out meal compared with the dormitory group (p < 0.05, p < 0.05, p < 0.05 respectively). The self-boarding group had a significantly lower the score of 'eat vegetables and Kimchi at every meal' (p < 0.001) and 'eat a variety of food everyday' (p < 0.001) compared with the dormitory group. The self-boarding group had a significantly higher the preference for meat products (p < 0.05) and canned food (p < 0.01) for selecting processed food compared with the dormitory group. The consideration for selecting processed food was ranked by 'taste', 'price', 'expiration', 'appearance' and 'nutrition' in both dormitory and the self-boarding group. In the dormitory group, nutrition labels were identified certainly 2.6%, sometimes 12.8%, and rarely 17.2%. In the self-boarding group, nutrition labels were identified certainly 1.7%, sometimes 18.0%, and rarely 24.8%. The necessity of nutrition education was high in both dormitory group (51.6%) and the self-boarding group (62.4%). Therefore, development of an educational program and application of the information from nutrition labels for male college students, especially self-boarding students will be effective in improving dietary life in order to maintain healthy dietary habits.

This study conducted a survey with 203 single households among men and women in their 20s to 40s who were living in metropolitan areas from October 6 to November 4, 2012 in order to investigate the dietary attitude of the single households. The ratio of single households who had three meals a day regularly was 2.85 points, which was lower than the normal level, and it turned out that those in their 20s and 30s had meals more regularly than those in their 40s did (p<0.001). As for the irregular meal time, most were breakfast (85.9%), and it turned out that they often skipped meals mostly because they did not have time to eat and (41.7%) or because that bothered them (26.0%). 62.6% of the single households did overeating and most of them (39.4%) did overeating because of their irregular meals. Of the single households, women or persons who had lived alone for less than 3 years or more than 7 years cooked at home, more often (p<0.05), and most of them (42%) cooked noodles, easy to cook, but women cooked Korean food-based homemade food such as rice (31.7%) or soup and stew (21.2%), often (p<0.05). It turned out that 36.9% of the single households often ate out about two to three times a day, and as for their favorite eating-out menus, 39.4% were Korean food, followed by Western food (23.8%), flour-based food (13.5%), fast food (9.8%), Chinese food (7.3%) and Japanese food (6.2%). Lastly, as for inconveniences when they ate out, most were the 'price' (22.8%), followed by 'too much amount of food for one person' (20.2%) and 'limitations in menu selection' (19.2%). As a result of this study, it appeared that the single households had an irregular dietary life, often did overeating and often ate out, so it is judged that it would be necessary to develop a variety of nutritionally-balanced HMR food and eating-out menus in a reasonable price range for their healthy dietary life.

A study has been performed to provide the basic information about the current dietary habits, health related behaviors, and body indices and to bring forward the importance of this information to the people's attention based upon the relation between employee's life patterns and health conditions in their daily lives. Three hundred and five department store workers were examined from August 2006 to September 2006. With the average BMI values $23.9{\pm}2.2$ for males and $20.0{\pm}1.9$ for females, both gender groups were in normal, but 62.2% of the males were overweight and 15.4% of the females were under-weight. Regarding dietary and health related factors on how they perceive themselves, as normal were 204 (66.9%) the most and bad and very bad were respectively 43 (14.1%) and 5 (1.6%). Half of the subjects (43.2%) perceived sleeping hours to be insufficient, and 64.4% of them need to exercise regularly. As problems related to eating habits, they reported irregular meal times, overeating, preference of hot and spicy food, skipping meal, unbalanced meals. Regarding weight control they have attempted were the most (73.0%), after weight reduction, 51.2% of the subjects had side effects, such as gastrointestinal troubles, anemia, dizziness, sense of fatigue, constipation, physiological disorder, and diarrhea, etc. In the food habit score, it was shown that overall average score of the subjects was $62.63{\pm}9.86$ which is lower than other studies. Female ($62.76{\pm}10.15$) had better score than male ($61.67{\pm}8.06$). While the item with the highest point was eat all three meals of the day, that was the lowest point, exercise every day. The food habit score of the younger group had lower than older group, and also they preferred sweet foods to other group. The results suggest that nutrition education for workers at specific working fields needs to be more focused on the improvement of dietary habits and health status of workers.

In this study, focus group interviews were used to investigate female university students' eating behavior, factors related to eating behavior, information sources for nutrition, and formats for nutrition education. Thirty-six students participated in one of five focus groups during December 1998 in Seoul. Focus group discussions were video, audio-taped, transcribed and analyzed by major themes. Results showed that subjects have undesirable eating behaviors, such s eating irregular meals and skipping meals. These behaviors are caused by a lack of time, habit, or for the purpose of losing weight. The students tended to have unbalanced diets and frequently ate out. They had a large amount for dinner and frequently snaked when stressed or had an empty stomach. Most of them were interested in weight control and had attempted to lose weight, but they did not participate in regular exercise. The most frequently used source for nutrition information was the mass media, but much nutrition information was based on what they learned from home economics class during middle to high school. They received more support from mothers, elder sisters, and friends for eating behaviors, such s lowering caloric intake and losing weight. In nutrition education, they wanted to learns behaviorla skills to adopt healthy behaviors, including meal planning, applying scientific weight control methods, exercise that fit into their lives, and stress management. They also mentioned that nutrition screening and assessment should be a part of nutrition education programs. As a method for nutrition education, subjects preferred an individualized approach to group education. These results provide the qualitative information for developing nutrition education programs which will be implemented for Korean University students.

This study examined the effectiveness of nutrition education and program using the diet rice bowl during a four-week diet program. Thirty-eight female college students were randomly assigned to a nutrition education (NE) group or a nutrition education and diet rice bowl (ND) group. The mean energy intake of the NE and ND group during the program was 1,130.8 kcal and 1,287.4 kcal, respectively. The total energy intake of both groups were significantly decreased during the program. In addition, the change of body weight and fat in both groups significantly decreased during the program. The NE group lost 2.8 kg of body weight and 1.4% of body fat, while the ND group lost 2.5 kg of body weight and 1.2% of body fat. The changes in total cholesterol and LDL-cholesterol in both groups also significantly decreased during the program. However, there were no significant differences in the changes of body weight, body fat mass, the total cholesterol and LDL-cholesterol between the two groups. This study could not identify a weight reduction effect of the diet rice bowl, however, this may be due to subjects' infrequent use of the diet rice bowl by their frequent meal skipping and eating-out in our study. Therefore, further studies regarding the compliance to the diet rice bowl should be conducted to examine its effectiveness on weight control.

This study was conducted to assess the perception of nutritional education by students in elementary school and their parents in terms of the degree of satisfaction with school foodservices. The survey was conducted on 322 parents and 322 students using a questionnaire. Most of the students and parents were satisfied with the school foodservices, the most satisfactory component of school foodservice was the "balanced nutrition intake". The students and parents acquired nutritional information from the "school letter" and "Mass media". They trusted professional dietitians, the school and the nutritional information acquired from accredited mass media. In regards to the type of nutritional education, 28.9% of parents preferred "clinical nutrition information on disease" and 26.9% of parents preferred "nutrition information of food". In contrast, 33.7% of the students preferred the "clinical nutrition information on disease" and 25.4% of the students preferred "right eating habit (unbalanced eating, skipping meal)". The top three reasons for wanting to provide offspring with nutritional information was "right eating habit" (48.9%), "correction of unbalanced diet" (19.8%) and "healthy physical strength" (12.1%). The dietitians need professionalism to deliver accurate information and knowledge relating to the subjects that the users demand and the development of teaching media should be conducted to effectively deliver this knowledge.

Since the economic crisis in 1997, the number of low income families has increased and the turmoil is likely to affect nutritional and health status of the children in low-income families. The purpose of this study was to investigate dietary behaviors and physical development of low income family children in the Seoul area. The subjects were 44 boys and 56 girls, between the ages of 7 and 12 years, from the beneficiary families of the governmental assistant program and enrolled in after school-care centers. A self-reported questionnaire, including general characteristics and dietary behaviors, was applied to the children and their parents. Skipping meal rate was higher in breakfast than in lunch or dinner, and was less frequent in parents and children families compared to that of the other types of families (p<0.05). Most students are shown that they usually keep the dietary guideline for Korean children. There were significant differences in keeping the dietary guidelines between the parents and children family group and other groups in several items. The results imply that the nutrition education program should be more focused on the families which are not composed of parents and children.
