This is the Study of descriptive research to look into influence factors about how pain, nutritional risk, loneliness and perceived health status have an effect on the health-related quality of life. The subjects were 110 elderly women living alone over the age of 65 living in D gu, Y gu, D metropolitan city and collected data by giving questionnaire, and used the SPSS/WIN 18.0 version to analyze. The correlated factors of health-related quality of life included pain(r=-.565, P<.001), nutritional risk(r=-.485, P<.001), loneliness(r=-.546, P<.001) and perceived health status(r=.706, P<.001). Factors influencing health-related quality of life are perceived health status, loneliness, pain, type of residence, number of diseases. Therefore, in order to improve health-related quality of life for elderly women living alone, it is necessary to induce the practice of education and health behavior for improvement of health status, to establish social network to increase emotional support and to apply various protection systems.

This study was carried out to investigate the future plan for infant feeding practice and its associated factors among university students so as to develop focus for nutritional education program for the promotion of breastfeeding. The subjects were 301 students (males 130, females 171). The results obtained were as follows. In this survey, the subjects had a basic knowledge of breastfeeding and lactation, especially of the ingredient of breastmilk. However they were not well informed about the physiology and method of breastfeeding and benefits of breastfeeding for mothers. The average scores far attitude toward breastfeeding and lactation were 3.09 points on a 4 point scale, which indicated a slightly positive attitudes toward breastfeeding. However the participants had a negative attitude toward its emotional and practical aspects. Their future plan for infant feeding was breastfeeding 40.3%, formula feeding 3.0% and mixed feeding 56.7%. A concern was that the students showed a high rate with regard to a mixed feeding plan, and Dey decided this based on an incorrect knowledge of breastfeeding. The group who planned to breastfeed in the future (BF) showed higher scores with respect to knowledge and attitudes than those who planned to formula feed or mixed feed (FF + MF). Therefore, to encourage mothers to breastfeed and support breastfeeding, breastfeeding nutritional education is urgently needed among university students. In addition, nutrition education programs should promote the benefits of breastfeeding for mothers and the physiology and practical method of breastfeeding. Also a practical and culturally sensitive course about food and nutrition is recommended to inform participants about breastfeeding. (Korean J Community Nutrition 8(2) : 240∼249, 2003)

Galactosemia is a rare genetic metabolic disease caused by galactose and its metabolites generated during carbohydrate metabolism, which is relatively rare in Asian countries, including Korea. Patients with galactosemia should be treated with a galactose-restricted diet. However, information is lacking about the exact content of galactose in food, and dietary guidelines for patients with galactosemia in Korea. This study aims to recognize the difficulties faced by parents and clinical experts of patients with galactosemia, and understand their demands. Totally, 5 parents of children diagnosed with galactosemia and 5 clinical professionals participated in the focus group interviews. The parents' interview focused on the daily life of the patient, which included diet and social difficulties. The clinical experts mainly answered about medical care, including the number and status of patients, and their suggestions for effective treatment. Most parents were worried about social isolation due to conflicts in the family as well as in society due to a lack of understanding of the disease. The clinical experts stated the absence of a disease management system as the greatest problem. An integrated support system for patients with galactosemia, which includes appropriate dietary guidelines by considering the domestic environment, is required.

In this paper, we developed a workout and diet assistance application to meet the growing demand for workout and dietary support services due to the increase in the home training population. The application analyzes the user's workout posture in real-time through the camera and guides the correct posture using guiding lines and voice feedback. It also classifies the foods included in the captured photos, estimates the amount of each food, and calculates and provides nutritional information such as calories. Nutritional information calculations are executed on the server, which then transmits the results back to the application. Once received, this data is presented visually to the user. Additionally, workout results and nutritional information are saved and organized by date for users to review.

Backgrounds/Aims: Early recovery after surgery has become a popular trend. The aim of this study was to evaluate effect of nutritional intervention using Encover, an oral nutritional supplement, in patients undergoing hepato-biliary-pancreatic surgery. Methods: This single center, prospective case-control study was conducted in Gangnam Severance Hospital from September 2018 to April 2019. Through randomization, patients were divided into an experimental group (30 patients) and a control group (30 patients). At postoperative seven days, the experimental group was instructed to take two packs of Encover (JW Pharmaceutical, Seoul, Korea) daily for seven days. Body cell mass index was measured at seven days after surgery and 14 days after discharge and Patient-Generated Subjective Global Assessment (PG-SGA) was performed at 14 days after discharge. Results: Body cell mass index during outpatient follow-up was significantly decreased compared to that at discharge in both groups. However, the amount of body cell mass index showed no significant difference between postoperative seven days and outpatient follow-up in either group. During outpatient follow-up, the experimental group had a higher mean value of PG-SGA score than the control group (11.32 ± 3.46 vs. 9.48 ± 3.97; p = 0.037). Conclusions: Short-term Encover doses after surgery may not produce significant results in weight gain or other body cell mass index. Encover did not significantly affect other dietary conditions based on PG-SGA.

This study was designed to examined psychosocial status and nutritional factors(nutrition knowledge, dietary attitudes, eating behavior, dietary intakes) among female university students and to investigate if there were differences in these variables by weight loss attempt. A cross-sectional survey was conducted to 225 female university students in Seoul. Survey instrument was adapted or modified based on literature review, and dietary intakes were assessed using 24-hour recall and CAN-pro. Descriptive statistics, t-test x$^2$-test were used in data analysis. Mean height, weight of subjects were 162.7cm, 51.3kg, and mean BMI was 19.4. One hundred-nine students(48.4%) were grouped into weight loss attempt roup and 116 students were grouped int non-attempt group. According to BMI, 58.7% of weight loss attempt group were underweight, suggesting that unnecessary weight control is common in college women. With respect to psychosocial status, subjects received moderate degree of stress and were slightly satisfied with life. There was no significant difference in stress, social support or self-esteem between the two groups, however, students in non-attempt group were more satisfied with their life(p<0.01) and adapted better in school that students in weight loss attempt group. Subjects scored 14.9${\pm}$2.1 (highest score : 20) on nutritional knowledge, and showed favorable dietary attitudes. Overall, nutritional knowledge and dietary attitudes were not significantly different between the two groups. Common eating problems were irregular meals(71.6%), followed by unbalanced meals and eating-out. Subjects in weight loss attempt group were more likely to change eating habit after entering the university and showed more undesirable eating habit. Dietary intake data indicated hat the energy derived from fat was slightly higher than the recommended level. Most of the nutrient intake was lower than the RDA, particularly, iron and calcium intake was below the 50% of the RDA. Although this study did not reveal significant difference in nutritional knowledge or dietary intake by weight loss attempt, this study showed status of weight control, eating habit and dietary intake in female university students, and provide some information for nutrition education of college women.

BACKGROUND/OBJECTIVES: This study aimed to identify preschool children's eating behaviors associated with early childhood obesity and its multi-level, socio-ecological determinants. SUBJECTS/METHODS: In a cross-sectional study of 364 mothers of preschool children aged 3-5 years, these children's healthy eating behaviors were assessed using a validated preschool nutrition quotient (NQ-P) questionnaire. The children's overweight or obesity statuses were determined based on body mass index percentiles from the 2017 Korean National Growth Chart. The associations between the NQ-P score and risk of overweight or obesity were examined using multivariable logistic regression. The associations of individual, maternal, physical, and media environmental factors with the NQ-P score were also examined using multivariable linear regression. RESULTS: Preschool children with greater NQ-P scores were at a significantly lower risk of overweight or obesity (P < 0.01). The NQ-P score had a significantly positive association with maternal body mass index and an inverse association with household income (all P < 0.05). Maternal parenting and feeding practices exhibited associations with the NQ-P score. Positive associations were observed with "warm," "structured," and "autonomy-supportive" parenting as well as monitoring feeding practices (all P < 0.05). In addition, the NQ-P score had a significantly positive association with the childcare center's anti-obesogenic environment, such as the provision of nutritional and physical-activity support and vicinity of the built food environment to the home, including access to good-quality food, fruits and vegetables, and low-fat foods (all P < 0.05). Regarding media environments, the NQ-P score demonstrated more significant associations with viewing and eating and/or cooking content displayed on online video platforms (all P < 0.05) than with that on television. CONCLUSIONS: Our findings confirm the significance of healthy eating behaviors in early-childhood-obesity prevention and underscore the importance of multilevel maternal, physical, and media environmental interventions that effectively guide eating behaviors in preschool children.

Purpose: A comprehensive evaluation item was developed to assess adolescent dietary habits and nutritional practices, considering food intake, eating behaviors, and food culture, such as social support and food environment. Methods: The 59 candidate items of the evaluation checklist were obtained based on the results of the eighth Korea National Health and Nutrition Examination Survey data, Korea Dietary Reference Intakes, dietary guidelines for adolescents, Youth Risk Behavior Survey data, national nutrition policies and dietary guidelines, and literature reviews. Four hundred and three middle and high school students residing in metropolitan areas participated in a survey using the 58-item checklist, which was selected through expert evaluation and content validity ratio analysis. The construct validity of the assessment tool for the quality of adolescent diets was assessed by exploratory factor analyses to determine if the checklist items were organized properly and whether the responses to each item were distributed adequately. Results: The Bartlett sphericity test was significant for each area (p <0.001), and the eigen values were greater than one. The Kaiser-Meyer-Olkin and cumulative proportions by areas were food intake (0.765 and 56.8%, respectively), eating behaviors (0.544 and 64.8%, respectively), and food environment (0.699 and 62.4%, respectively). Twenty-two checklists were determined for the final evaluation items for the adolescents' dietary habits and nutritional practices and were categorized into three distinct factors: food intake (10 items), eating behaviors (4 items), and food environment (8 items). Conclusion: The evaluation items for adolescent dietary habits and nutritional practices is a useful checklist for easily and quickly assessing the dietary qualities and reflecting Korean adolescents and their food environmental factors related to a sustainable diet.

The purpose of this study was to provide fundamental data for health promotion and improvement of the dietary life in students who receive school lunch support (SLS) by comparative analysis of food service satisfaction, dietary habits, and nutrition intakes according to SLS. The subjects of this study consisted of 258 boys and 233 girls at a middle school in Incheon. The students' average age was 14.9 years, average height was 161.3 cm, and average weight was 52.0 kg. The breakfast eating frequency of the No-SLS (NSLS) group was significantly greater than that of the SLS group (P<0.05). The time spent for eating breakfast in the SLS group was significantly shorter than that of the NSLS group for boys. There was no significant difference in dietary attitudes according to SLS. For satisfaction of the quantity and diversity of the school lunch menu in girls, the SLS group had higher satisfaction than the NSLS group. The daily energy intake of the SLS group was significantly lower than that of the NSLS group in both boys and girls. The majority of daily nutrients intakes in the SLS group were also significantly lower than those in the NSLS group. In summary, the female students in the SLS group were more satisfied with school lunch service than general students. However, SLS students less frequently ate breakfast and showed lower energy and nutrient intakes. Therefore, in order to improve the nutritional status and dietary life of students who receive school lunch support, consistent nutrition management and support in schools are required.

Long-chain (LC) n-3 polyunsaturated fatty acids (n-3 PUFAs), in particular docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are nutrients involved in many metabolic and physiological processes, and are referred to as n-3 LCPUFA. They have been extensively studied for their effects in human nutrition and health. This paper provides an overview on metabolism, sources, dietary intake, and status of n-3 LCPUFA. A summary of the dietary recommendations for n-3 LCPUFAs for different age groups as well as specific physiological conditions is provided. Evidence for n-3 LCPUFA in cardiovascular diseases, including new studies, is reviewed. Expert recommendations generally support a beneficial effect of n-3 LCPUFA on cardiovascular health and recommend a daily intake of 500 mg as DHA and EPA, or 1-2 servings of fish per week. The role of n-3 LCPUFA on brain health, in particular neurodegenerative disorders and depression, is reviewed. The evidence for beneficial effects of n-3 LCPUFA on neurodegenerative disorders is non-conclusive despite mechanistic support and observational data. Hence, no definite n-3 LCPUFA expert recommendations are made. Data for the beneficial effect of n-3 LCPUFA on depression are generally compelling. Expert recommendations have been established: 200-300 mg/day for depression; up to 1-2 g/day for major depressive disorder. Recent studies support a beneficial role of n-3 LCPUFAs in reducing the risk for premature birth, with a daily intake of 600-800 mg of DHA during pregnancy. Finally, international experts recently reviewed the scientific evidence on DHA and arachidonic acid (ARA) in infant nutrition and concluded that the totality of data support that infant and follow-on formulas should provide both DHA and ARA at levels similar to those in breast milk. In conclusion, the available scientific data support that dietary recommendations for n-3 LCPUFA should be established for the general population and for subjects with specific physiological conditions.
