To evaluate the effect of feeding methods on growth and zinc nutritional status of infants early in life, we monitored from birth to 36 months in 51 infants who were exclusively fed human milk (HM, n=20), casein-based formula (CBF, n=12), or soy-based formula (SBF, n=19) during the first five months of life. Zinc status was assessed by analyzing serum zinc concentrations and zinc intakes. Zinc contents in HM and formulas were measured. Zinc intake was estimated by weighing infants before and after feeding in the HM group and by collecting formula-intake records in the CBF and SBF groups. After solid foods were introduced, all foods consumed were also included to estimate zinc intake. The growth of infants in all groups was similar to that established for normal Korean infants. Human milk zinc concentrations declined as lactation progressed. Zinc concentrations in all formulas tested in this study were higher than HM and were also higher than those claimed by the manufacturers. During the first twelve months, mean serum zinc concentrations of infants were similar in all groups, although infants in the HM group consistently had the lowest zinc intake among the groups, and the overall zinc intake in infants fed SBF was highest. This finding could be explained by the difference zinc bioavailability of HM and formulas. In conclusion, infants fed HM, CBF or SBF has normal growth up to three years of age, although HM contained the lowest zinc concentration followed by CBF, then SBF.

This study examined the needs and practice willingness for the health promotion program of restaurant industry among Seoul residents. Using structured self-administered questionnaires, data on subjects' general characteristics, health status, and eating out behavior characteristics, the needs and practice willingness of the health promotion program for restaurant industry were collected from 765 adults above the age of 19. The needs for nutrition labeling such as fat, calorie, sodium, fiber, and the practice willingness for consuming nutrition labeled food were high. Results showed that gender, restaurant's management status, and food quality status were significant indicators for needs for health promotion program. Education duration, food quality status, and the frequency of eating out were significant variables for practice willingness. The results imply that health promotion program for the restaurant industry should be based on the consumer's characteristics. Also, the results imply the necessity of several activities such as social marketing to inform the benefit of participation in the health promotion program for consumers, guidance to maintain the food quality and improve the ambiance of restaurant for suppliers, and the new establishment of research centers to validate the labeled information on meals and analyze the nutrients of the meals for agencies.

Objectives: This study investigated the health and nutritional status of the elderly according to the number of chronic diseases, using data obtained from the Korea National Health and Nutrition Examination Survey 2013~2015. Methods: Data from a total of 2,310 individuals, aged 65 years and over, were used for the analysis. The elders were divided into 0 (n=375), 1 (n=673), 2 (n=637) and 3 or more (n=625) groups, by considering the number of chronic diseases. Results: Compared to other groups, the elderly subjects who were living with their spouse had the highest ratio in group 0 (P < 0.05), whereas subjects without economic activities had highest ratio in 3 or more group (P < 0.05). The EQ-5D index of subjects in the 0 group (0.90 ± 0.01) was higher than that in the 3 or more group (0.86 ± 0.01) (P < 0.05). After adjusting for confounding factors, the energy intake of subjects was determined to be lowest in the 3 or more group (P < 0.05). Protein (P < 0.05) and riboflavin (P < 0.05) intakes of the 3 or more group were also lower than other groups. Conclusions: This study indicates that multimorbidity of the elderly is associated with their health and nutritional status. The nutrients intake of the elderly, especially energy, protein and riboflavin, tended to be lowest in the 3 or more group. Further research is required to elucidate the risk factors related to presence of multimorbidity in the elderly.

This study was conducted to assess biochemical nutritional status and health status of 53 men and 130 women aged over 65 years and residing in low-income areas in Seoul. Nutritional status and health status were determined by hematological analysis, incidence of disease, and clinical symptoms. Mean serum cholesterol levels were 159.7mg/dl in men and 182.4mg/dl in women and triglyceride levels were 124.6mg/dl in men and 130.6mg/dl in women. The serum lipid levels were higher in women than in men, and 88% of the subjects belonged to normal range and 12% belonged to hyper lipid. The mean hematological indices.; Hb, Hct, RBC, MCH, serum iron belonged to normal ranges. The proportion of anemic state were 16~18% in men and 20~25% in women. Mean serum Ca, Cu and Zn levels were 9.4mg/dl, $84.2\mu\textrm{g}/dl$ and $75.8\mu\textrm{g}/dl$ for male and $9.5\mu\textrm{g}/dl$, $88.3\mu\textrm{g}/dl$ and $75.6\mu\textrm{g}/dl$ for female, respectively. However, proportion of low Ca, Cu and Zn status were 8~20%, 77~84% and 12~34%, respectively. The biochemical indices were not significantly different according to age, BMI, obesity rate. Cholesterol, RBC, MCH and serum iron levels were significantly different between men and women. (Korean J Community Nutrition 1(2) : 215-227, 1996)

This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P<0.001) and of depression (P<0.001) improved significantly and that dietary behavior scores also improved significantly (P<0.001), while nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P<0.001). These results indicated that nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals.

BACKGROUND/OBJECTIVES: Food literacy (FL) is a crucial skill for selecting sustainable and healthy food options, necessitating the identification of vulnerable groups in the community using valid measurement tools. Identifying weak domains in FL is essential for enhancing the overall FL. This study examined the FL levels of Seoul citizens based on their sociodemographic characteristics and assessed the relationship between FL, food intake, and weight status. SUBJECTS/METHODS: This study utilized the data from the Seoul Food Survey, a cross-sectional study employing representative samples of Seoul citizens. Data collection occurred from September to October 2021, with 4,039 citizens aged 18 yrs and above participating in face-to-face surveys. Thirty-three FL items were assessed, comprising 14 items in the nutrition and safety (NS) domain, eight items in the cultural and relational (CR) domain, and 11 items in the socio-ecological (SE) domain. In addition, data on food intake sufficiency and obesity status were collected. The descriptive statistics, t-tests, analysis of variance, and logistic regression analysis were used for analysis. RESULTS: Men, students, young adults, older citizens, and people experiencing food insecurity had the lowest scores for all the FL domains. The highest quartile group of NS scores had a higher probability of consuming adequate servings of vegetables and fruits, with significant linear trends observed (P for trend < 0.05). In all three FL domains, the odds ratio for obesity was significantly lower in the groups with high FL scores (P < 0.05). CONCLUSIONS: A close relationship was observed between low FL, obesity, and food intake, even after controlling for other covariates. Vulnerable groups with low FL were also identified. Therefore, it is essential to develop programs to improve FL and the health and well-being of these groups.

Purpose: Body adiposity is negatively correlated with hepatic iron status, and Korean pine nut oil (PNO) has been reported to reduce adiposity. Therefore, we aimed to study the effects of PNO on adiposity, hepatic mineral status, and the expression of genes and proteins involved in iron absorption. Methods: Five-week-old male C57BL/6 mice were fed a control diet containing 10% kcal from PNO (PC) or soybean oil (SBO; SC), or a high-fat diet (HFD) containing 35% kcal from lard and 10% kcal from PNO (PHFD) or SBO (SHFD). Hepatic iron, copper, and zinc content; and expression of genes and proteins related to iron absorption were measured. Results: HFD-fed mice had a higher white fat mass (2-fold; p < 0.001), lower hepatic iron content (25% lower; p < 0.001), and lower hepatic Hamp (p = 0.028) and duodenal Dcytb mRNA levels (p = 0.037) compared to the control diet-fed mice. Hepatic iron status was negatively correlated with body weight (r = -0.607, p < 0.001) and white fat mass (r = -0.745, p < 0.001). Although the PHFD group gained less body weight (18% less; p < 0.05) and white fat mass (18% less; p < 0.05) than the SHFD group, the hepatic iron status impaired by the HFD feeding did not improve. The expression of hepatic and duodenal ferroportin protein was not affected by the fat amount or the oil type. PNO-fed mice had significantly lower Slc11a2 (p = 0.022) and Slc40a1 expression (p = 0.027) compared to SBO-fed mice. However, the PC group had a higher Heph expression than the SC group (p < 0.05). The hepatic copper and zinc content did not differ between the four diet groups, but hepatic copper content adjusted by body weight was significantly lower in the HFD-fed mice compared to the control diet-fed mice. Conclusion: HFD-induced obesity decreased hepatic iron storage by affecting the regulation of genes related to iron absorption; however, the 18% less white fat mass in the PHFD group was not enough to improve the iron status compared to the SHFD group. The hepatic copper and zinc status was not altered by the fat amount or the oil type.

This study was undertaken to investigate iron status and related factors in female college students residing in Gyeongnam. The subjects were divided into normal (40.8%) and iron deficiency (ID) groups (59.2%) by iron status. Mean height, weight, lean body mass, percent body fat, body mass index, and wrist to hip ratio were not significantly different between the groups, but basic metabolic rate was significantly higher in the normal group than that in the ID group. The levels of hemoglobin, hematocrit, serum ferritin, transferrin saturation, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were significantly higher in the normal group than those in the ID group. However, total iron binding capacity was significantly lower in the normal group than that in the ID group. Daily intake of protein, heme-Fe, niacin, and vitamin C were significantly higher in the normal group than those in the ID group. The mean intake of protein, Fe, niacin, vitamin $B_{12}$, and vitamin C based on the Korean recommended intake (RI) were significantly higher in the normal group than those in the ID group. The mean intakes of Ca, vitamin $B_{12}$, and folate in both groups were < 75% of the Korean RI. In conclusion, increasing dietary heme-Fe and vitamin C may be helpful for preventing ID anemia in female college students.

This study investigated nutritional status and eating behaviors among 59 nephritic patients with mild kidney malfunction in Korea. Nutritional status was measured by blood analysis and 1-3 day dietary recall and records, and eating behaviors were assessed by a questionnaire. Mean Body Mass Index(BMI) was within the normal range, while 21% and 14% of the patients were underweight and overweight, respectively. They received nutrition information mainly from doctors, nurses and mass media, but rarely from nutrition professionals. A quarter of patients skipped breakfast at least 3 times per 12% of the patients, respectively. Energy intake of 83% of the patients was less than the recommended level. Protein intakes of 56% of them were either under or over the recommended levels. Patients had low vitamin B$_2$ and calcium(<75% of the RDA) and excessive phosphorus(138% RDA) and vitamin C(170% RDA). Major food sources to absolute nutrient intakes were similar to those for the average Koreas, except for milk. Milk intake was low in our patients. Dietary quantity and quality were associated positively with BMI, albumin, and HDL-cholesterol and negatively with triglycerides and BUN. Results of this study indicate low nutritional status of the patients and, in turn a need for conducting nutritional education or counselling at regular at regular basis for the nephritic patients with mild kidney malfunction.
