Purpose: This study analyzes the association between depression, emotional eating, and dietary practices, and investigates the mediating effects of emotional eating between depression and dietary practice. Methods: A total of 345 women aged 40-59 years participated in the Seoul and Gyeonggido region. Assessments were achieved by self-reported questionnaires for emotional eating (Dutch Eating Behavior Questionnaire), Nutrition Quotients (NQ), and depression (Patient Health Questionnaire-9). Results: Analyzing the NQ scores by considering the depression group, revealed that compared to the normal group, balance, diversity, and eating behavior scores were lower in the depression group, whereas the moderation score was lower in the borderline depression group and depression group. The emotional eating scores were determined to be higher in the depression group than in the normal group. Partial correlation analysis between depression, emotional eating, and NQ revealed that depression is positively correlated with emotional eating and negatively correlated with all other factors of the nutrition quotient, balance, diversity, moderation, and eating behavior. Among the nutrition quotient factors considered, emotional eating was determined to be negatively correlated with both diversity and moderation. The bootstrapping method was applied to analyze the mediating effect of emotional eating for determining the association between depression and NQ. Results indicate that among the nutrition quotient factors evaluated using emotional eating as a medium, depression exerted a negative effect on moderation. Conclusion: Results of this study confirm that emotional eating, as a medium, affects the intake of unhealthy foods especially when depression is associated with dietary practices.

Iron deficiency is the most common nutritional problem that affects people of all ages in both industrialized and developing countries. Especially, college women are the target population for dietary iron deficiency. Recent study showed that the nutritional status of college women was poor because of insufficient food consumption and repeatabled weight reduction. The purpose of this study was to investigate the effects of nutrition counseling on the diet quality, nutritional status of iron and hematic parameters in college women who have self-recognized anemic symptoms. Anthropometric and dietary assessments as well as blood analysis, were carried out before and after the 8 weeks of nutrition counseling. During the experimental period, the 31 subjects were given nutrition education by a clinical dietitian. Nutrition counseling consisted of pathology of anemia, nutrition information for iron deficient anemia, diet information of balanced meals and menu choices for eating out. As a result, the frequencies of consumption of legumen and vegetables significantly increased after nutrition counseling(p<0.05). Daily intakes of protein, especially animal protein, vitamin E, niacin, heme iron, and zinc significantly increased(p<0.05). After nutrition counseling, some self-reported clinical symptoms such as 'dizziness', 'fatigue', 'short of breath', 'headache', 'sleeplessness', and 'beating heart' were significantly improved. Serum levels of transferrin(p<0.01) and total iron binding capacity levels(p<0.05) significantly increased. It could be concluded that the 8 weeks of nutrition counseling might be effective on quality of diet as well as iron status and it might also improve the some hematic parameters in college women who have self-recognized anemic symptoms.

Purpose: This study set out to evaluate the compliance to, and efficacy of oral supplementation, using a 1.5 kcal/mL or 1 kcal/mL sip feed, in children with mild to moderate malnutrition. Methods: This was a parallel, randomized, controlled open-label trial in children aged 3 to 6 years with a weight for height Z (WHZ) score <-1 and ${\geq}-3$, who were randomized to receive a total of 600 kcal/day from either a 1.5 kcal/mL or a 1.0 kcal/mL pediatric sip feed for 28 days. Assessments included daily study product intake, body weight, tolerance and dietary intake from solid food. Results: Of 110 children recruited, 98 ($mean{\pm}standard$ deviation of age $49{\pm}7months$) completed the study. Both sip feeds were well tolerated, with high compliance ($80{\pm}24%$ and $81{\pm}22%$ of prescribed volume in 1.5 kcal/mL and 1.0 kcal/mL groups respectively, p=0.79). Both study groups gained similar weight during the 28 days intervention period ($0.42{\pm}0.40kg$ in 1.5 kcal/mL group vs. $0.49{\pm}0.49kg$ in 1.0 kcal/mL group, p=0.43). There were no significant differences between the groups in weight gain and in the change in WHZ score over the intervention period. Dietary analysis at the end of the study did not show replacement of solid food by the oral nutritional supplements. Conclusion: In children with mild to moderate malnutrition, both 1.5 kcal/mL and 1 kcal/mL pediatric sip feeds had high compliance and were well tolerated, and were equally effective in promoting weight gain in the 28 days study period.

This study was conducted to evaluate the textural and sensory properties of Kong-sulgidduk prepared with two types of soyflour (yellow and black) according to the amount of added glutinous riceflour. The rheological properties of Kong-sulgidduk were changed by the amount of added glutinous riceflour. When the amount of added glutinous riceflour was increased from 10% to 40%, hardness, gumminess, and brittleness were significantly increased in the sulgidduk prepared with yellow soyflour. In the case of black soyflour, the addition of 10% glutinous riceflour began to increase in the gumminess and brittleness. The addition of 30% glutinous riceflour effected a significant increase in hardness. The addition of yellow soyflour resulted in higher cohesiveness, gumminess and brittleness scores than those of black soyflour. The results of color assessments demonstrated that the more glutinous riceflour was added to the sulgidduk, the lower were the L-values; however, as the b- and a-values of the sulgidduk prepared with yellow soyflour increased. The addition of the same quantity of glutinous riceflour to the sulgidduk prepared with black soyflour resulted in a reduction in a- and b-values as compared to the sulgidduk prepared with yellow soyflour. In our sensory evaluation, with to the increasing quantities of added glutinous riceflour, the moisture and chewiness values clearly increased. However, the addition of 10% glutinous rice flour resulted in the highest overall quality. Also, the addition of 20% and 30% black soyflour resulted in better scores than the yellow soyflour samples in terms of color, moisture, and overall acceptability. These results demonstrated that the addition of glutinous riceflour to Kong-sulgidduk improves the textual and sensory properties.

Polyphenolic flavonoids are among a wide variety of phytochemicals present in the human diet. Basic research, animal model, and human studies suggest flavonoid intake may reduce the risk of several age-related chronic diseases. The vast number of flavonoids and mixtures of their subclasses, including flavonols, flavones and flavanones, and the variety of agricultural practices that affect their concentration in foods have presented a challenge to the development of adequate food composition databases for these com-pounds. Nonetheless, dietary assessments have been applied to cohort and case-control epidemiological studies and several reveal an inverse association with risk of some forms of cancer, cardiovascular disease, and other chronic conditions. Those observational studies that have examined these relationships with regard to flavonols, flavones, and flavanones are reviewed. The requirement for caution in interpreting these studies is discussed with regard to the limited information available on the bioavailability and biotransformation of these flavonoids. As the totality of the available evidence on these flavonoids suggests a role in the prevention of cancer and cardiovascular disease, further research is warranted, particularly in controlled clinical trials.

The purpose of this study was to investigate Na and K balances in healthy adult women. Anthropometric assessments, biochemical analysis of blood, 3-day dietary flood records and collections of 3-day food, 24-hr urine and faces were performed to evaluate intakes and excretions of Na and K in 20 college women living in Seoul. The mean BMI and blood pressure of the subjects were 21.08 and 110.25/67.50mmHg, respectively. Mean daily intake of energy was 1578.84kcal, 79% of Korean RDA. Also, daily intakes of Na and K ware 120.86mEq and 44.20mEq. The urinary and fecal excretions of Na were 99.88 and 4.45mEq/day, and those of K were 30.41 and 8.66mEq/day, respectively. The body retention, retention rate, and apparent absorption of Na were 17.11mEq, 13.23%, and 96.31%, and those of K were 5.82mEq, 8.69%, and 80.12%, respectively. The urinary and fecal Na/K ratio were 3.48 and 0.52. There were significantly positive correlations between 1) urinary Na, K excretions and intakes of Na or K, 2) urinary K and BMI, 3) serum K and serum globulin, and 4) urinary Na excretion and serum haptoglobin level, respectively. The results of this study show that Na intake was higher and K intake was lower than those of other advanced nations. Therefore, nutrition education show instruct people to reduce Na intake and to increase K intake.

The purpose of this study was to investigate the anthropometry, biochemical parameters and electrolytes concentrations of the Total Parenteral Nutrition (TPN) patients according to their nutritional status at the time of admission. Thirty-three patients in the Intensive Care Unit at S University Hospital were the subjects of this study. Their nutritional status was classified as At-risk I (Mild PCM, n = 13), At - risk II (Moderate PCM, n = 9) and At-risk III (Marasmus + kwashiorkor + severe PCM, n = 11) . Anthropometeric, biochemical and dietary assessments were performed. The Patients intake of calories (75.02%) and protein (53.15%) was insufficient compare with Korean RDA requirements. The body weight and the Body Mass Index (BMI) in the At-risk III group were significantly lower than in the other groups. The percentage of body weight loss and change of body weight (kg) were significantly higher than in the other groups. The subjects were malnourished as indicated by nutritional related parameters such as serum total protein, albumin, total lymphocyte count (TLC), hemoglobin and hematocrit. Serum total protein, albumin and TLC levels were lower at the time of admission before TPN administration. But after TPN administration, they increased. The electrolyte concentrations did not show any differences following TPN administration. The nutritional status of the patients could be affect by the duration of TPN administration and the number of days of the patients hospitalization. The patients who require nutritional support need the continuous follow-up care and monitoring by a nutritional support team. (Korean J Community Nutrition 8(4) : 574-583, 2003)

Purpose: This pilot study aimed to assess the feasibility, preliminary efficacy, and effects of a mobile app healthcare coaching program developed based on self-regulation theory among youths with type 1 diabetes. Methods: A mixed-method design was utilized. Participants were randomly assigned into intervention (n=23, 12-week coaching program) or control groups (n=16, usual care). Pre- and post-intervention assessments included self-efficacy, diabetes management behavior, and health outcomes (quality of life, depression, and HbA1c). Quantitative data were analyzed with SPSS/WIN ver. 26.0. The narrative information from the participants in the healthcare coaching program underwent content analyzed. Results: The intervention group had significantly lower depression scores (t=2.57, p=.014) than the control group. No significant differences were observed in self-efficacy, diabetes management behavior, and health outcomes between the two groups. The average frequency of health behavior monitoring per week among the participants was 1.86±1.60. The qualitative findings indicated that participants perceived improved diabetes self-management with the intervention; however, challenges during vacations, dietary control difficulties, and a lack of disease awareness were identified. Conclusion: The healthcare coaching program improved psychological aspects for youth with type 1 diabetes. Further research is needed to develop and implement mobile app interventions aimed at enhancing compliance with diabetes management in pediatric and adolescent populations.

This study was to investigate the effects of a silk peptide, and prune and raspberry mixture on the body fat, serum lipid composition and fat distribution in Korean women during the time they received these supplements. During the 4 month period of this research (June to October, 2002), 75 women (average age 22.9 yr) were selected as subjects. Their nutrient intake was investigated by use of a questionnaire and the 24-hour recall method. Antropometric assessments of the subjects were investigated by using the SBIA Method (Segmental Bioimpedance Assay, Inbody 3.0). The results were as follows: their mean body weight was 59.3 kg, their mean body height was 161.7 cm and their mean Basal Metabolic Indices (BMI) was 22.7. The status of their dietary fiber intake significantly increased (p < 0.05) after use of the supplements. Their body fat significantly decreased following the $3^{rd}$ stage of supplementation (p < 0.05), and their percent of body fat signiflcantly decreased after supplementation (p < 0.05). Their triceps and suprailiac circumference significantly decreased following the $3^{rd}$ stage of supplementation (p < 0.05). Their waist circumferences and waist-hip ratios (WHR) significantly decreased after both the $2^{nd}$and $3^{rd}$ stage of supplementation (p < 0.05). Their total cholesterol significantly decreased following the $3^{rd}$ stage of supplementation, as compared to their baseline results and those obtained following the 1$^{st}$ stage of supplementation (p < 0.05). Their LDL-cholesterol and LDL / HDL ratios significantly decreased following the $3^{rd}$ stage of supplementation, as compared to their baseline results and those obtained following the 1$^{st}$ stage of supplementation (p < 0.05). Their 4-HNE and total antioxidant statuses significantly decreased following the $2^{nd}$ and $3^{rd}$stage of supplementation, as compared to their baseline results and those obtained following the $1^{st}$ stage of supplementation (p <0.05). Their $2^{nd}$ stage supplementation results were significantly negatively correlated with their triceps measurements and WHR (p < 0.05). Their $3^{rd}$stage supplementation results were significantly negatively correlated with their anterior thigh measurements (p < 0.05). The above results show that prune, raspberry, silk peptide and dietary fiber supplementation to a routine diet improves body fat distribution, total cholesterol, and triglyceride levels. The decrease of abdominal fat and WHR were especially noteworthy. This implies a decrease of risk factors. (Korean J Community Nutrition 8(3) : 356~367, 2003)003)

Purpose: The 2020 Dietary Reference Intakes for Koreans (KDRIs) serves as a foundation for daily nutrient and energy recommendations aiming to enhance public health and prevent chronic diseases. They act as guidelines for maintaining proper nutrition and overall health. Using KDRIs is crucial for promoting healthier lifestyles and making informed dietary choices. Thus, this study explores the influence of a nutrition education program, based on the 2020 KDRIs, on the nutrition knowledge and dietary habits of undergraduates in Gyeongsangnam-do and Gyeonggi-do. Methods: The nutrition education program, designed with diverse instructional materials, was executed across a wide range of universities. The education group (n = 75) engaged in the program for a 6-week instructional period, while the control group (n = 53) underwent the survey without participating in the education program. Nutrition Quotient (NQ) and knowledge assessments were administered to both groups immediately before and after the instructional period. Results: Within the education group, the nutrition education program positively impacted responses to NQ practice items, including knowledge of nutrition, daily intake, and portion sizes (p < 0.05). In contrast, there were no significant differences between the before and after responses of the control group for most survey items. Post-program evaluations showed significantly higher self-assessment scores and increased satisfaction levels (p < 0.05), with the satisfaction rate for the education program using the 2020 KDRIs reaching 99.2%. Conclusion: This study has demonstrated the positive impact of an effective nutrition education program. However, there is a need for the continuous development and implementation of nutrition education programs to sustain these outcomes and further enhance the nutritional education experience.
