Purpose: This study investigates the relationship among nutrition knowledge, food habit problems and dietary attitudes in nursing students. Methods: A total of 856 nursing students participated in the study. Data was analyzed by frequencies, t-tests, ANOVA, Pearson correlation coefficients, and multiple stepwise regressions via SPSS WIN 21.0. Results: The mean scores for nutrition knowledge and dietary attitudes were above average and the score related to food habit problems was high. Dietary attitudes correlated positively with nutrition knowledge, but dietary attitudes correlated negatively with food habit problems. Significant predictors of dietary attitudes included: food habit problems, interest in nutrition and health, exercise, and drinking. The regression model explained 16.4% of perceived dietary attitudes. Conclusion: To improve dietary attitudes among nursing students, nursing educators should develop nutritional educational intervention programs in order to promote nutrition knowledge and identify food habit problems.

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 effects of 10-week dietary education on elementary students in an after-school program in Seoul. Participants were 20 1-2 grade students and 283-6 grade students, and the dietary program consisted of dietary education and activities focused on children's levels of understanding. The results were as follows: Total participant's food habit scores and nutrition knowledge significantly increased (p<0.05) after dietary education. Food habit and nutrition knowledge scores of lower grade participants (grade) increased desirably (p<0.05). Meanwhile higher grade participants' (grade) food habit scores also changed (p<0.05), but their nutrition knowledge scores were changed. Boy's food habit scores significantly changed (p<0.05), whereas girl's food habit scores did not change significantly. Further, female participants' nutrition knowledge scores did not changesignificantly after education. Participants' obesity knowledge scores significantly changed after the education (p<0.05), but their attitudes on obesity increased insignificantly. Lower grade participants' attitudes on obesity significantly and desirably changed (p<0.05), whereas higher grade participants' attitudes on obesity changed insignificantly. Girl's knowledge and attitudes on obesity significantly and desirably changed (p<0.05-0.01). This study revealed the correlation between food habit scores and attitudes on obesity (p<0.01), demonstrating that participants with high food habit scores have advisable attitudes on obesity. The result of this study shows that lower grade participants' food habit scores, nutrition knowledge, and attitudes on obesity changed desirably after dietary education. Therefore, this study promote the development of adequate nutrition education and materials focused on lower grade students and the need for systematic and continuous dietary education programs based on elementary school.

This study was performed to investigate the relationships among personality preferences, dietary habit and nutrient intake of University students (n=283). Mean dietary habit score was similar between sexes and was 46.1/100 in male students and 45.1/100 in female students. Average energy intake of male students was 2,019 kcal (80.8% of RDA) and that of female students was 1,675 kcal (83.7%). Male students were taking less than 90% of RDA in calcium and vitamin $B_2$ and female students were taking less than 90% of RDA in calcium, iron, vitamin C, and vitamin A. Students preferring Judgment had significantly higher dietary habit score than students preferring Perception. Extraversion had higher nutrient intake than Introversion both in male and female students. Male students preferring Feeling had also higher nutrient intake than students preferring Thinking. Nutrient density per 1,000 kcal was higher in Thinking and Judgment than Feeling and Perception. In conclusion, students preferring Judgment and Extraversion have better dietary habit and nutrient intake than those preferring Perception and Introversion. More studies are necessary between personality preferences and dietary behavior to contribute to effective nutrition education and counseling.

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.

This study was performed in order to investigate the relationship between attention deficit hyperactivity disorder (ADHD), dietary habit and caffeine intake in upper-grade elementary school children. The total number of the study subjects was 237 students (111 boys and 126 girls), where 30 students (12.7%) were diagnosed as ADHD. The dietary habit score of the ADHD group was significantly lower than that of the normal group. In particular, the ADHD group had lower dietary scores in consuming daily breakfast, diverse foods, fruit and milk than those in the normal group. Meanwhile, the daily intake frequency of instant noodle (ramyeon) was significantly higher in the ADHD group than that in the normal group. The mean caffeine intake of the students was 42.95 mg and the proportion of students consuming more than the ADI (acceptable daily intake) was 11.8%. The caffeine intake of ADHD group (63.63 mg) tended to be higher than that of the normal group (39.95 mg); however, it was not significantly different. The ADHD score of the students was negatively related with the dietary habit score (r = -0.279, p < 0.01) but positively related with caffeine intake (r = 0.164, p < 0.05). The dietary habit score had a negative relationship with caffeine intake (r = -0.180, p < 0.01) and a positive relationship with height (r = 0.195, p < 0.01). Caffeine intake had a negative relationship with the height of the students (r = -0.171, p < 0.05). In conclusion, ADHD in children was related to poor dietary habit and high caffeine intake.

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.

The purpose of this study is to evaluate the relationship of blood pressure with dietary habit and level of physical fitness of middle-aged male workers by age. The study subjects included 511 male employees who have worked at a company in C City, whose age was more than 40 years old. Between April 10 and May 30. 1998, all of the study subjects measured physical fitness (Balance, strength, power, agility, flexibility and endurance) and blood pressure. A questionnair was administered for dietary habit and socio-demographic characteristics. The average age (SD) of the study subjects was 46.61(3.98) years. The study subjects were classified by age into 3 groups; 40-44 aged group(34.6%), 45-49 aged group(41.3%), and 50-54 aged group (24.1%). The score of dietary habit of 40-44 aged group was $69.77{\pm}5.82$. that of 45-49 aged group was $69.77{\pm}5.83$, and that of 50-54 aged group was $71.85{\pm}6.82$(p=0.005). But age of health physical fitness tend to weaken in the age of 40-44. Systolic(p=.011) and Diastolic blood pressure (p= .011) were significantly increased with age increment. Diastolic blood pressure and dietary habit of 45-49 aged group showed the significant negative-correlation(r= .280. P<0.05). and Diastolic blood pressure and age of health physical fitness of 40-44 aged group showed the significant positive-correlation(r= .182. P<0.05). On the basis of the results of this study. I hope occupational nurses should play an active role to improve dietary habit and physical fitness for prevention of hypertension with increase of age in middle-aged male workers.

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.
