It is well known that malnutrition is a predictor of mortality in hemodialysis patients. The number of diabetic nephropathy patients is increasing rapidly. This study aimed to investigate nutritional status and nutrient intake according to the presence of diabetes among hemodialysis patients. The nutritional intake and general characteristics of outpatients at Ajou University Hospital (24 with diabetes and 30 without diabetes) were investigated between July and September 2015. Patients' general data were collected, and nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) was evaluated. Nutrient intakes were assessed according to 3-day food records. There was no significant difference regarding body weight between the two groups. However, the non-diabetic group showed a better nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) ($5.2{\pm}4.4$ vs. $8.0{\pm}4.3$ score, non-diabetics vs. diabetics, P<0.05). There was no difference in daily calorie intake ($1,473.9{\pm}370.5$ vs. $1,503.8{\pm}397.5kcal$) and protein intake ($60.3{\pm}19.7$ vs. $65.6{\pm}20.5g$) in those with diabetes. Intakes of vegetables protein, sodium, potassium, vitamin C, folic acid and fiber were significantly higher in the diabetic group compared to those of the non-diabetic group. There was no difference in daily nutrient intake between the hemodialysis weekday and weekend groups. The non-diabetic group had higher calorie and sodium intakes per meal in the hemodialysis weekday group, but the difference was not significant. Based on these results, intervention should be performed to improve nutritional status in consideration of diabetes and dietary patterns.
Protein efficiency ratio (PER), net protein utilization (NPU), nitrogen digestibility (ND), organ weights, and amino acid composition were investigated for rapeseed protein isolates (RPI) prepared by alkaline countercurrent extraction and isoelectric precipitation of defatted rapeseed meal (DRM). The PER values for 3 kinds of RPI obtained at pI of 6.7, 5.6 and 5.0 were 2.8, 3.1 and 2.9, and for DRM 2.5 while the NPU values for these RPI appeared to be 68, 73 and 71 %, and for DRM 56 %, respectively. Mean ND (85%), food intake (87), and weight gain (37.6) for RPI were significantly different from those of DRM (71 %, 77, and 28, respectively). There was no signicant difference in the PER among three RPI and casein (3.0), nor in the NPU among those proteins and casein (74%). These data attributed to the favorable amino acid patterns of proteins isolated which contained balanced essential amino acids in proportions which meet the requirements of human adult(FAO/WHO, 1973).

This study examined how consumer choices (i.e., selecting food safety certified products, health-related products, and familiar brands) affect the purchase of Korean native chicken (KNC) and the demographics that influence KNC purchases using secondary consumer panel data from the Rural Development Administration of Korea. The grocery purchase data from 654 Korean households between 2017 and 2019 were used; the propensity for food safety certified products was measured by the purchasing frequency of Good Agricultural Practice (GAP) and Hazard Analysis and Critical Control Point (HACCP) products, and the propensity for health-related products was measured by the purchasing frequency of home meal replacement (HMR) and hedonic products. The propensity to purchase familiar brands was measured using a questionnaire. Logistic regression was used to examine the determinants of the KNC purchase experience, and multiple linear regression was used to determine the factors that influenced the KNC purchase frequency. The results showed that unemployed women purchased more safety certified products, health-related products, familiar brands, and KNC. These findings suggest that targeting consumers with differential marketing strategies may help promote KNC consumption. This study identified factors that influence KNC purchases, which is important for understanding consumer behavior and revitalizing the market.
Purpose: This study aimed to analyze the trends in kimchi, vegetable, and fruit consumption among the Korean population and identify the factors associated with this consumption. The goal was to provide fundamental data for developing appropriate guidelines to increase kimchi consumption by understanding its characteristics. Methods: The analysis utilized data from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted between 1998 and 2020. A total of 81,680 adults, aged 30 years or older, were included in the trend analysis. For the analysis of factors associated with kimchi, vegetable, and fruit intake, a subgroup of 22,122 adults aged 30 years or older from the KNHANES (2016-2020) was divided into two groups: 30-64 years old and 65 years old or older. Since the KNHANES data employed a complex sampling design, the statistical analysis was conducted using the appropriate complex sampling design method. Results: The overall consumption of kimchi exhibited a declining trend among both men and women. Specifically, there was a significant decline in the intake of baechu kimchi among both genders. The decline in kimchi consumption above the standard was associated with a decrease in meal frequency and an increase in the frequency of eating alone. However, the patterns for unsalted vegetables and fruits differed compared to kimchi. Conclusion: In this study, there was a decline in kimchi consumption among both men and women, and the potential factors associated with this trend included Westernized dietary habits, the presence of a spouse who influenced dietary habits, and an increased frequency of solitary dining due to the rise in single-person households. Therefore, it is necessary to develop dietary guidelines that consider these factors.
Purpose: Given that the indicators related to chronic diseases are important to evaluating goals of the national health policy, the aim of this study was to develop dietary behavior items available in the Korea National Health and Nutrition Examination Survey. Methods: The dietary behavior items were developed based on the literature reviews, need assessment of the field, expert focus-group interviews, and expert advisory meeting. Questions for each dietary behavior item were developed by reflecting on environmental, personal, and behavior factors of the ecological frame and then revised through expert focus-group interview and expert advisory meeting. The understanding and reliability of the developed questionnaire were assessed by cognitive interview and test-retest reliability. Results: The developed items were sodium and salt intake, added and simple sugar intake, enough time to consume a meal for all ages, caffeine drinks and fresh/healthy food intake for children and adolescents, and limited dietary intake, fresh/healthy food intake for seniors. In most questions except some questions on sodium and salt intake, subjects understood over 70% and consistency of responses based on the kappa values was acceptable. Conclusion: Developed dietary behavior items are expected to be useful for evidence-based nutrition policy, interventions and research targeting dietary patterns through investigating and monitoring dietary behavior patterns.
Food habits and Korean food utilization patterns were surveyed from 188 Koreans residing in New Zealand and Malaysia by using a questionnaire. Forty seven percent of the respondents answered that Korean food should be succeeded as its traditional form. Most subjects had strong pride for Korean traditional food. Kimchi was the most frequently consumed side dish followed by Chigaes (stew), broiled meat, Tubu (bean curd), broiled fish, Tangs (soup), and Noodles. While Kimchies were prepared by the respondents themselves, Doenjang and Kochujang were sent from the relatives in Korea or purchased from the market. The changes in food consumption pattern after emigration depended on the availability of food items in residing country. Korean style meal (cooked rice and side dishes) was eaten by 51% respondents for breakfast and by 78.2% for supper. Ramyon was the most frequently consumed instant food. Eating out frequency was much higher in the residents in Malaysia than the ones in New Zealand. This study showed that Koreans residing in foreign countries have the consciousness trying to succeed Korean traditional food culture, and their food consumption pattern partly depends on food availability and socio-cultural properties of the residing country.
The purpose of this research is to examine the awareness and preference for a variety of Kimchi and Kimchi intake patterns among the students living in Chungbuk province. Four hundred samples, consisting of elementary, middle, and high school students, were surveyed; and a total of 366 usable, completed copies of the questionnaire were used for the research. The collected data were statistically analyzed using SPSS 10.0. The results of the analysis were as follows: First, Kimchi was considered traditional (24.3%), nutritious (20.5%), fermented (l9.2%), and healthy (16.1%). Second, the main reason Kimchi was preferred was its "hot taste" (25.4%), "chewy texture" (17.4%), and "sour taste" (14.0%). The students preferred their Kimchi a little hot, moderately salty, and properly fermented with a moderate amount of seasoning and did not care much about any particular parts of Kimchi. Third, 75.4% of the students ate Kimchi more than twice a day, and 78.0% of the students consumed more than 3 pieces($2.5{\times}3.0cm$) of Kimchi per meal. Fourth, elementary students wanted the school foodservice to develop bite-sized Kimchi while middle school students wanted to eat their favorite parts of Kimchi without the fishy smell. High school students wanted to eat cool and fresh Kimchi. Finally, the students wanted Kimchi to contain the following fruit and vegetables: pears (48.9%), apples (34.2%), and pineapples (30.0%), young radishes (44.9%), turnips (37.5%), and sesame leaves (34.9%). This study concludes that it is necessary to educate young students about traditional Korean food culture, serve them various types of Kimchi, change the service style, and develop new Kimchi recipes to increase Kimchi intake in school foodservices.
Objectives: The aim of this study was to investigate dietary intakes and nutritional status among Uganda primary school children from two selected schools in urban and rural areas. Methods: Data were collected from 350 pupils (6-14 years) in Mpigi district, Uganda. All participants were offered a school lunch meal (usually maize porridge and boiled beans). Dietary survey was conducted in October 2016. Data for dietary intake levels were collected by the 24-hour recall method with trained school staffs. The data were converted into nutrient intakes using the CAN-Pro 5.0 Program and compared with KDRIs to evaluate the nutritional status of the subjects. Diet quality indexes such as nutrient density, nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) and a diet diversity index such as diet diversity score (DDS) were calculated to evaluate nutritional status among subjects. Data were analyzed using SPSS statistical programs. Results: Results show that the intakes of most nutrients were significantly different by schools. The nutritional status of micro-nutrients was very low in both schools according to analysis of nutritional indexes such as NARs and INQs. Students from both schools should improve intakes of micro-nutrients related to child growth such as calcium, Vitamin B6, zinc and folate. According to the analysis of dietary diversity, there was difference in dietary patterns by schools presumably due to their locations. Conclusions: This suggests that current meals could not provide adequate nutrients for the subjects and urgent nutrition interventions for school food services are needed to improve their nutritional well-being. New foods supplements based on local cuisine are also needed to ensure dietary diversity and sustainable development plans.
Purpose: This cross-sectional study aimed to document the dietary behaviors, dietary changes, and health status of female marriage immigrants residing in Gwangju, Korea. Methods: The survey included 92 female immigrants attending Korean language class at a multi-cultural family support center. General characteristics, health status, anthropometric data, dietary behaviors, and dietary changes were collected. Results: Mean age of subjects was 31.3 years, and home countries of subjects were Vietnam (50.0%), China (26.0%), Philippines (12.0%), and others (12.0%). Frequently reported chronic diseases were digestive diseases (13.2%), anemia (12.1%), and neuropsychiatry disorder (8.9%). Seventeen percent of the subjects was obese ($BMI{\geq}25kg/m^2$). Dietary score by Mini Dietary Assessment was 3.45 out of 5 points. Dietary scores for dairy foods, meat/fish/egg/bean intake, meal regularity, and food variety were low, and those for fried foods and high fat meat intake were also low. Thirty-three percent of subjects answered that they have changed their diet and increased their consumption of fruits and vegetables after immigration. Length of residence in Korea was positively associated with BMI and waist circumference. Length of residence tends to be positively associated with dietary changes and obesity as well as inversely associated with disease prevalence. Conclusion: The study shows that length of residence is inversely related to disease prevalence. However, this association is thought to be due to the relatively short period of residence in Korea and thus the transitional phase to adapting to dietary practices. As the length of residence increases, disease patterns related to obesity are subject to change. Healthy dietary behaviors and adaptation to dietary practices in Korea in female marriage immigrants will not only benefit individuals but also their families and social structure. Therefore, varied, long-term, and target-specific studies on female marriage immigrants are highly needed.
Purpose: The aims of this study are to examine clinical characteristics, patterns of medical care utilization, and factors which determine medical care utilization of elementary school children with recurrent abdominal pain (RAP), to find posssible factors influencing the onset and the course of the disorder. Method: We performed questionnaires in Kwangju on children from two primary schools from June,1 1998 to June 30 and carried out statistical analysis. Result: 1) Total number of questionnaires were 1417. 715 were male and 702 were female and the ratio of male to female was 1.02:1. Average age was 10.3 years. 2) 268 children had RAP (18.9%), boys 132 (18.4%), girls136 (19.2%). 3) The duration of the pain within 10 minutes was 68.5%. 178 children with RAP (66.3%) visited the doctor. The utilization pattern of medical facilities of the pupils with RAP; the most frequently utilized medical facility was pediatrics (35.2%) and the order ran as internal medicine (31.5%), and pharmacy (29.25). The utilization pattern of medical facilities for the older students; the utilization rate of pediatrics decreased, but internal medicine increased. The major factors affecting the selection of the medical facility were geographic accessibility, kindness of the personnel, good results and traffic convenience. 4) Symptoms which were accompanied with abdominal pain were headache (44.5%), chest pain (28.2%), dizziness (26.6%), vomiting (9%), and 119 children (44.5%) had no accompanied symptoms. 5) In 95 children (35.3%) abdominal pain, occured at postprandial time, in 55 children (20.5%) before meal and in 39 children (14.7%) at school. The highest incidence rate of RAP was observed on Monday (21.4%), and the lowest on Saturday (8.7%). 6) The most frequent involved part of the abdomen was periumbrical area (38%) and the order ran as epigastrium and suprapubic area. The most frequent characteristics of abdominal pain were burning pain (36.9%) and the order ran as dull, cramping and colicky pain. Conclusion: RAP is a frequent disease entitiy in children. Too many times children with RAP are treated by other departments instead of Pediatrics. A child has a peculiar growth and development which is different to those from an adult with advancing years. So, it is necessary to choose special medical care and an adequate medical facility.
