Data are limited on the association between dietary patterns and screen time among Korean adolescents. The present study identified dietary patterns of 691 adolescents, aged 13-18 years, who had participated in the Third Korean National Health and Nutrition Examination Survey (KNHANES III) and analyzed their associations with screen time. Screen time was defined as the time spent watching TV, using a computer, or playing video games was calculated as a sum of all these times. Dietary patterns and their factor scores were derived from a food frequency questionnaire using the factor analysis method. To analyze the association between dietary patterns and screen time, we conducted multiple linear regression analysis. We also performed multiple logistic regression analysis to estimate odds ratios (OR) of excessive screen time (2 hours or longer per day) and 95% confidence intervals (CI). We identified 2 dietary patterns labeled "the Korean healthy dietary pattern" and "the Western diet and fast foods pattern". The former included mixed grains, legumes, potatoes, red meat, eggs, fish, dairy products, fruits, vegetables, seaweeds, and mushrooms, whereas the latter included noodles, bread, red meat, poultry, fast foods, snack, and soft drinks. After controlling for potential confounding factors, factor scores for the Korean healthy dietary pattern were inversely associated (P-value for trend < 0.01) and those for the Western diet and fast foods pattern were positively associated with the screen time (P-value for trend < 0.01). Adolescents in the top tertile of the scores for the Korean healthy dietary pattern had a multivariable-adjusted OR [95% CI] of 0.44 (0.25-0.75) for excessive screen time compared with those in the lowest tertile. On the basis of these findings, adolescents who have excessive screen time may need to be encouraged to consume a more healthy diet.

Trans 지방산 섭취 수준을 파악하기 위하여 부산지역 중학생 800명을 대상으로 식행동 조사와 3일간의 식사기록법을 실시하였다. 식행동 조사에서 조사대상자들의 간식회수는 1일 2회 (35.3%)가 가장 많았으며, 간식 시 선호하는 식품은 아이스크림 (68.2%), 우유(57.0%), 파이(26.4%) 등이었다. 외식 시 선호하는 식품으로는 자장면(54.6%), 양념통닭(50.5%), 닭튀김(35.3%)등의 순이었다 1일 평균trans지방산 섭취수준은 남학생 1.40$\pm$0.05g,여학생 1.89$\pm$0.06g이며 전체평균 1.68$\pm$0.04g으로 여학생이 남학생보다 높았으며, 유의적인 차이가 있었다(p<0.001). 우유와 유제품, 육류 및 가공품 등에 포함되어 있는 천연적으로 생성되는 trans 지방산의 섭취 수준은 평균 1.04 $\pm$ 0.03 g으로 1일 trans 지방산 섭취량의 약 62.1%였으며 인공적으로 생성된 trans지방산의 섭취 수준은 평균이 0.64$\pm$0.02g이며 총 trans지방산 섭취량의 37.9%로 나타났다. 남ㆍ여 평균 trans 지방산의 섭취량은 1일 섭취 총 열량의 0.8%, 1일 총 지방의 3.16%였다. Trans 지방산 섭취수준은 여학생일 경우 용돈수준이 4만원에서 5만원 미만이 가장 높았으며, 간식빈도는 거의하지 않는 경우(2개월에 2회)가 4.56$\pm$1.55 g으로 가장 높았다. Trans 지방산 섭취의 주요 급원은 우유 및 유제품(34.3%), 빵류(18.3%), 어육류와 가공품(16.2%)의 순이었다. 본 연구의 결과, 우리나라 국민 전체의 trans지방산 섭취수준은 외국에 비해 그다지 높은 수준은 아니지만 현재의 식생활 패턴과 변화 추이를 볼 때 앞으로 tran지방산 섭취수준은 증가될 것으로 예상되므로 한국인의 trans지방산 섭취수준에 대한 연구 분석이 계속 진행되어야 할 것으로 사료된다.

본 연구에서는 초등학교 1학년에서 4학년까지의 급식 아동 중 편식이 있는 아동들을 선정하여 각 학년마다 비슷한 인원수로 교육군과 교육을 받지 않는 대조군으로 배정하였다. 교육군은 영양사가 직접 주 1회 8주간 영양교육을 학년마다 분리하여 실시하였으며, 교육군과 대조군 모두 교육 전후에 영양지식, 식생활 태도, 편식과 관련된 식이 자기효능감, 편식교정인자, 일반 식습관 등을 조사하여 영양교육에 따른 변화를 비교하고자 하였다. 영양지식과 식생활태도는 교육집단은 교육 전 $4.1{\pm}2.0$점과 $18.9{\pm}3.7$점에서 교육 후 $9.5{\pm}2.3$점과 $22.4{\pm}2.7$점으로 각각 유의하게 증가하였다(p<0.01, p<0.001). 그러나 식생활태도는 교육집단의 경우 교육 후 10항목 중 7항목에서 유의적인 변화를 보여 긍정적인 변화를 보인 반면, 대조군은 모든 항목에서 유의적인 변화를 보이지 않았다. 편식과 관련된 식이 자기효능감은 영양교육에 의해 저지방.저열량 조리법의 음식을 선택할 항목을 제외하고 개선되어 $9.9{\pm}2.8$에서 $12.6{\pm}2.0$으로 유의적 향상을 보였다(p<0.001). 편식교정인자는 영양교육에 의해 편식 여부, 식습관 수정 필요, 편식하는 식품군, 새로운 음식이나 싫어하는 음식에 대한 태도 등이 유의적으로 변화하였다. 그러나 기름을 많이 사용한 식품의 섭취, 간식섭취에 의한 결식, 인스턴트와 패스트푸드 섭취 항목은 영양교육에 의해 개선되지 않았다. 교육에 의해 편식유형 중 육류.생선.우유군 및 콩류.곡류.감자군에 대한 편식이 현저하게 감소하였다. 일반 식습관 총점은 영양교육에 의해 유의적으로 향상되었으며(p<0.001), 조사된 세부 항목 중 올바른 간식 섭취횟수, 김치를 포함한 세 가지 이상 반찬 섭취, 외식 습관, 가족과 함께 먹기를 제외한 다른 일반 식습관은 유의적으로 개선 되었다. 영양교육 후 편식교정인자는 영양지식이나 식생활태도, 식이 자기효능감과 역의 상관성을 보여(r=-0.323, r=-0.389, r=-0.310), 교육에 의해 향상된 영양지식, 식생활태도, 식이 자기효능감은 편식교정 필요를 낮출 수 있음을보였다. 한편 일반 식습관은 영양지식, 식이 자기효능감, 식생활태도와 정의 상관성을 보여(r=0.306, r=0.298, r=0.383), 영양지식의 개선은 식이 자기효능감을 높이고 식생활태도를 개선하여 일반 식습관에 영향을 주었을 것으로 사료된다. 이와 같이 본 연구에서는 급식이 제공되고 있는 학교 현장에서 영양전문가인 영양사가 기존의 선행 연구에서 개발된 영양교육 프로그램을 이용하여 초등학생의 인지 수준을 고려한 학년별로 소규모로 실시한 영양교육은 아동의 영양지식, 식생활 태도, 편식과 관련된 식이 자기효능감 증진에는 대체적으로 효과적이었으며, 편식교정인자, 일반 식습관의 개선에는 부분적 효과가 있음을 보였다. 본 연구에서 시간적 제약과 영양교육 프로그램의 전달방법의 미흡으로 인해 이러한 일부 식습관의 개선효과가 제한적이었으므로, 앞으로 저학년 아동의 편식유형과 인지 수준을 좀 더 고려하여 자신감을 더욱 높이는 실천적 프로그램이 개발되어 학교현장에서 활용되어야 할 것이다.

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 investigate the dietary habits and daily intake of nutrients in college students. This survey was conducted using a self-administered questionaire. The average heights and weights were 173.5 cm and 72.3 kg of male students and 161.8 cm and 57.2 kg of female students. The average of BMI was $24.2kg/m^2$ of male and $21.9kg/m^2$ of female, and the value of male students was higher than the value of female students. The response to the daily meals was 54.6% for '$2{\sim}3$ times/week'. The regularity of mealtime was 41.7% for irregular and the frequency eating after nine was 45.7% for '5-6 times/week', respectively. The repast was 72.2% for 'overeating and little eating' and was a significant difference of male and female students (p<0.05). The eating rate was higher '$10{\sim}20min$'. As for breakfast food eaten, skipping breakfast was 23.6% for 'no/week' and female students were higher than male students (p<0.05). The frequency of snacks was 36.0% for 'nothing' of males students and 34.8% for '3-4 times/week' of female students (p<0.05). The type of snack was a significant difference of males and females students (p<0.01), and was the highest 75.0% for carbonated drinks of males and 37.5% for snacks of females. The eating due to stress solution was a significant difference of male and female students (p<0.01), and was the highest 23.0% for 'frequency' of males and 44.7% for 'sometime' of females. As for food intake of male and female students, the meat intake was 66.7% for 'everything of male and female students. The fish intake was 68.1 % for '1-2times/week'. The milk, milk products, eggs and beans were each 40.3%, 58.3%, 56.9%, 47.2% for '1-2 times/week' (p<0.05). The fat intake was 55.6% for '$1{\sim}2$ times/week'. The average consumption of energy was 58% of male and 67% of female of estimated energy requirement (EER). Their mean ratio of carbohydrate: protein: fat was 57 : 15 : 28 of all subjects. The mean intakes of vitamin C and folic acid were 70% and 51% of males and 62% and 52% of females of recommended intake (RI). The mean intakes of Ca, P, Fe and Na were 71%, 140%, 146% of males and 72%, 122%, 76% of female of RI and 273% of males and 233% of females of adequate intake (AI). Therefore, nutritional education is necessary for college students to establish physicall and mentall optimal health conditions though nutritional intervention.

This article concerned with the nutritional status and the taste of the lunch box of 311 middle school girls in Kwangju City from May 18 to June 12 in 1987. The purpose of this research was making materials to show direction of the education about nutrition by checking relationships among the nutritional status for the lunch box, the taste of food and the environmental factors. The results observed in the study were as follows: 1. The intake of nutrition from the lunch box and the ratio between the recommended dietary allowance and the contained nutrients in the lunch box as follows. Calorie(603 Kcal, 78.6%), protein (21.7g, 93.1%) Animal protein (10.3g, 132.1%) calcium (151.7 g, 56.9%) Ferrum 93.1 mg, 51.7%), Vitamin a (129.3 RE, 55.4%) Vitamin B1 (0.29 mg, 72.5%), Vitamin B (0.26 mg, 55.3%) Niacin (4.7 mg, 94.0%), Vitamin C 913.2 mg, 79.0%). Except animal protein, all the recommended dietary allowance. 2. According to the intake of calorie, the ratio of taken carbohydrate, protein and fat was 77.7 : 15.5 : 6.8. The intake of protein was desirable but most of calorie depended on carbohydrate. Among the total intake of protein, the ratio of animal protein was 47.5%, which was a high rate. 3. Most of calorie (75%), was taken from staples, protein (41.5%), vitamin B1 (48.3%) were taken at the same rate from staples and side dishes. Most of fat, calcium, ferrum, vitamin A, vitamin B, and vitamin C, was taken from side dishes. 4. In taking among the five basic food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food group was second, and Calcium food the second food group was the lowest. 5. As the staples, students liked tchajangmyon, mandu and ttokkuk as written order. They disliked Kongbap and Patpap. As the side dishes for the lunch box, they liked kimchi, ham, sausage, cuttlefish, dried slices of filefish, eggs and green seaweed as written order. As a side dishes they liked Laver, Cucumber, Squid, lettuce, Potatoes. They disliked pork fat, cow's intestines, cow's liver, Crussian carp, pickled fish. The favorite snack was fruits, ice cream, hamburger, Chocolate and milk. 6. In taking condition of the principal food, rice rate (65.6%) was the most, and mixed food was 5 or 10%. 7. Favorite cooking was frying, roasting and kimch. But disagreeable cooking was pickling. 8. Favorite food was what was pungent but disagreeable food was what was salty. 9. the higher parents educational background was, the higher their income was. Also the more various the information about the nutrition was, the better the intake of nutrition was. 10. The preference tendency influenced in choosing the side dish of the Lunch box. The higher the preference tendency of the girl students became, the better their nutrition condition became.

This study was aimed to examine nutrition knowledge, dietary attitudes, and eating habits of elementary school students and to examine if their characteristics differ by gender. Subjects were 5th and 6th graders of an elementary school (n = 317) in Seoul, and the survey was done during July 2007. Mean height, weight, BMI of subjects was 148.1 cm. 41.7 kg, 19.0, and 14.3% of subjects were categorized as the overweight/obese group. Anthropometric data were not significantly different by gender. Mean score of nutrition knowledge was 14.9 out of 20 showing moderate knowledge levels, and girls scored higher on nutrition knowledge than boys (p < 0.05). Subjects showed knowledge deficit in areas such as nutrients, food groups and specific weight control information. The percentages of correct answers regarding meals for brain function were significantly higher in girls than in boys (p < 0.05). They got nutrition information mainly from mass media and family/relatives. The mean score of dietary attitudes was 41.2 (possible score: 10-50) indicating somewhat positive attitudes, and the score of eating behaviors was 34.8 (possible score: 15-45). Subjects showed problems in eating habits such as having unbalanced diets and snack foods. 82.6% of subjects had unbalanced meals, and these percentages were higher in girls (87.2%) than in boys (78.1%, p < 0.05). Vegetables and fish/shellfish were the most disliked foods. Specific eating behaviors, such as eating slowly, eating grains and having processed foods less frequently, were better in girls than in boys (p < 0.05). Results also showed that majority of subjects need to improve specific behaviors including having diverse foods, eating meals slowly, having meals at regular times, having adequate foods in each food groups, and eating sweets or salty foods less frequently. Only 52.7% of subjects perceived their body images as normal, and 56.4% had experience of weight control. Reasons for weight control were different by gender (p < 0.05). Based on these findings, nutrition education for school children should focus on modifying eating habits or eating behaviors, by suggesting practically applicable methods and providing nutrition information that is interesting and suitable to school-aged children.

The purpose of this study was to investigate the dietary habits, the nutritional knowledge and the consumption patterns of convenience foods of 618 university students located in the Gwangju area, from November twentieth to November thirtieth, 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 far 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 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 28% respectively. Males ate fiequently cup Ramyon (2.08 $\pm$ 2.95), fries (pork cutlet, fried potato) (1.91 $\pm$ 2.58), Ramyon (1.81 $\pm$ 3.00) and kimbab (1.70 $\pm$ 3.17) more frequently, while females ate kimbab (2.25 $\pm$ 3.26), cup Ramyon (1.89 $\pm$ 2.09), fries (pork cutlet, fried potato) (1.77 $\pm$ 2.67), Ramyon (1.46 $\pm$ 1.1.95) and fish paste (1.45 $\pm$ 2.22) more frequently. The nutritional knowledge score was higher in females than in males. The mean consumption patterns of convenience foods of students living in home were lower than that of students living in dormitory and boarding w/cooking. When the amount of pocket money available and the body mass index increased and the nutritional knowledge level was low, the mean consumption of convenience foods increased. The mean consumption of convenience foods correlated negatively with nutritional knowledge (p < 0.01). Therefore, nutritional education for university students is needed so as to improve their health and nutritional education program should be developed to meet the various needs of these students.
