Objectives: The purposes of the study were to develop a questionnaire for dietary habit survey for Korean adults, and unify the terms related to dietary habits. Methods: The Delphi method by 43 professionals on dietary habit research was applied to unify the terms. Results: With regard to results on terms related to dietary habit, the respondents recorded the highest percentage (90.7%) of selecting the term "dietary habits" and also the highest percentage (76.7%) of choosing "dietary habits" for English. The biggest percentage of the respondents chose "individual dietary behaviors repeatedly formed and habitualized under the social, cultural, and psychological influence in the group" as the concept of dietary habits. The Delphi survey for the development of a questionnaire resulted in the first questionnaire of 31 items, the second one of 27 items, and the third one of 25 items. The validity of questionnaire items was tested with content validity ratios (CVR). The items whose CVR value was 0.29 or lower were eliminated or revised, because the minimum CVR value needed to test validity was 0.29. To test the reliability of questionnaire items, test-retest method was performed in 163 adults. According to the Kappa coefficient in the range of 0.314-0.716, all of the 25 items were in the reliability scope. A survey was taken with 702 adults to finally revise and supplement the third questionnaire whose validity and reliability were tested. Conclusions: Through those processes, a questionnaire for adults' dietary habit survey was finally completed. The significance of the study lies in the development of the first questionnaire on dietary habits equipped with both validity and reliability in South Korea.

The purpose of this study was to identify the relationships of optimistic bias about gastric cancer, self-efficacy of healthy dietary behavior and unhealthy dietary habit in Korean adult men. The subjects were 394 men aged from 20 to 64 who lived in Seoul, Kyonggi Do, Kwang-Ju, Jeonnam Do. Data was collected by questionnaire surveys using convenient sampling. The instruments used for this study were extracted and modified from Lee's(2003). The collected data was analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression with SPSS/PC 10.0 version. Unhealthy dietary habit in adult men indicated a significantly negative correlation to optimistic bias about gastric cancer(r=-.159, p=.002) and self-efficacy of healthy dietary behavior(r=-.470, P=.000). The most significant predictors influencing unhealthy dietary habit in adult men were age and self-efficacy of healthy dietary behavior. The variance explained was about 24%. These results suggested that men of young age and lack of self-efficacy of healthy dietary behavior are likely to have unhealthy dietary behavior. Therefore, considering age and facilitating self-efficacy are needed in nursing education and intervention for dietary habit change.

This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

This study was conducted to examine the relationship between dietary habits and time spent watching TV and using internet, in elementary school children. The data were collected by a questionnaire survey of 712 elementary school children, within Gwangju and Jeonnam area. The SPSS 12.0/win program was used to analyze the 523 samples. Amount of TV-watching time was found to be related to the dietary habit score in the subjects. The children who watch TV "less than 1 hour/day" on weekdays had a better dietary habit score than those who watch TV "more than 1 hour" (p<0.0001). The children who watch TV "less than 2 hours/day" on weekends had a better dietary habit than the children who watch TV "more than 2 hours/day" (p<0.0001). The internet usage was also related to the dietary habit score in these children: those who use internet "less than 1 hour/day" on weekdays had a better dietary habit score than the children who use internet "more than 2 hours/day" (p<0.0001). The children who use internet "less than 2 hours/day" on weekends had a better dietary habit score than the children who use internet "more than 2 hours/day" (p<0.0001). These results indicate that the children tend to have a better diet when their TV and internet time is limited and thus healthy dietary behavior is negatively associated with a sedentary pattern of activity in elementary school children.

This study was conducted to investigate the annual differences in food habits and dietary attitudes of new female college students enrolled in the department of food and nutrition for 6 years by questionnaire. The results were as follows: age, height, weight and body mass index(BMI) were no significant annual differences over study period. The average ratios of underweight, normal weight and above overweight groups classified by the BMI standard were 19.4%, 64.4% and 16.2%, respectively. There were no significant annual differences in the scores of food habits and dietary attitudes. The intake of milk showed the lowest scores among all the food habit items and the same annual tendencies for 6 years. Among food groups items, the mean intake scores of milk(p<0.01), fats and oils(p<0.001) and vegetables(p<0.05) differed significantly by year. Specifically, the intake scores of milk and vegetables decreased gradually throughout the study period and were significantly lower in 2008 than in 2003. Among dietary habits, the mean intake scores of sweets were significantly lower in 2003 and 2007 than in other years(p<0.001), and the mean intake scores of instant frozen foods were significantly higher in 2006 than during other years(p<0.05). The sum of health related items in 2007 was significantly lower than those during other years, and this was likely due to the lowest scores both of eating-out and alcohol intake in 2007 than in other years. Among dietary attitudes, the mean score of item 'Price of food is more important than nutrition.' was significantly lower in 2005(p<0.05). Food habit scores showed significantly positive correlation with dietary habits(r=0.733, p<0.01), food groups related habits(r=0.720, p<0.01), lifestyle related disease related habits(r=0.518, p<0.01), health related habits(r=0.422, p<0.01). Food habits and dietary attitudes showed highly significantly positive linear correlations each other(r=0.426, p<0.01). Dietary habits and food groups related habits showed highly significantly positive linear correlations(r=0.366, p<0.01). These results showed the same annual tendency with respect to food habit and dietary attitudes in newly enrolled college female students for 6 years. It is expected that food habit and dietary attitudes will be improved if systemic and proficient nutrition education is provided during their college period.

Objectives: A higher consumption of vegetables is emphasized as the core component of most dietary guidelines. Thus, this research investigated the dietary habits and influencing factors of vegetable preferences of adolescents. Methods: This study was conducted by using a self-administered questionnaire. 400 students from two high schools in Gyeongnam (193 boys, 207 girls) participated in the survey. The questionnaire consisted of the following variables: dietary habit, dietary action guide and factors based on Social Cognitive Theory (SCT). Results: The dietary habits of subjects showed significant differences depending on whether they prefer vegetables or not. The subjects in the group who liked vegetables had better dietary habits than the other group. Also, the study determined that the most important reason for liking or disliking vegetables is due to the taste. In the practice of dietary guidelines, the group of subjects who liked vegetables followed dietary guidelines more closely than the other group (p < 0.001). When the factors based on SCT were analyzed, personal factors showed significant differences between the groups: outcome expectation (p < 0.001), self-efficacy (p < 0.001) and affective attitude (p < 0.001). Personal factors and rated vegetable preferences showed a significant correlation in multiple regression analysis (F=42.015, p < 0.001). Conclusions: These results showed that vegetable preference is associated with a key point of desirable dietary habits among subjects. In order to increase vegetable preference or consumption, it is important to focus on strengthening not only self-efficacy of students, but also affective attitude of vegetable.

The purpose of this study was to investigate dietary habits, dietary attitudes, perceptions for nutritional importance, nutritional knowledge and frequency of food intake to get the basic data of effective nutritional knowledge to form desirable dietary habits of students. This study was carried out through a questionnaire. The subjects were 362 teenagers (boys 161, girls 201) in some farming and fishing regions of Jeonnam. The most desirable dietary habit was that both boys and girls never skipped their lunch, the undesirable dietary habit was that boys ate too fast and girls had too many snacks. While boys ate faster than girls (p < 0.01), girls skipped dinner more frequently than boys (p < 0.01). In terms of dietary attitudes, boys had more desirable attitudes than girls in that they "choose nutritious food" (p < 0.01), "enjoyed healthy food more than favorite food" (p < 0.01), "think about basic food groups when having something" (p < 0.01) while girls had more desirable attitudes than boys in that they "only have favorite food" (p < 0.01). In nutritional knowledge, girls showed a percentage of more correct answers than boys in "is likely to suffer anemia without enough iron" (p < 0.05), and "it doesn't need to eat fat, which causes obesity" (p < 0.05). In general, girls had higher nutritional knowledge than boys. For frequency of food intake, boys ate more fried and broiled food than girls (p < 0.05). In general, boys had nutritional unbalanced diets more than girls. As a result, girls had higher levels of nutritional knowledge and boys had more desirable dietary habits and attitudes. We should have systematic and repetitive education about nutrition so that teenagers could practice their nutritional knowledge in diets. Moreover, it is necessary to develop proper education for their genders.
