The purpose of this study was to compare the food behavior and nutrient intakes, and the analysis of constituent parts of blood related to iron nutrition conditions and to investigate the correlation between iron nutrition conditions and obesity. Each subject was assigned to one of such as normal(n=55) and obese groups(n=60) according to their obesity index. Their nutritional status, serum iron status were evaluated based in 24-hr dietary recalls, questionnaire and blood analysis. The mean age of the normal group(10.76 years) and that of the obese group(10.95 years) made little difference. The height(p<0.05), weight(p<0.001), and obesity index(p<0.001) in the obese group were higher than those of the normal group in every respect. The 63.55% of the subject of this study gave an answer 'They eat breakfast daily', and the frequency of eating breakfast made little difference. The average intakes of energy were 1669.44 kcal(84.19% of EER) in the obese group and 1673.59 kcal(86.72% of EER) in the normal group respectively, which made little difference between two groups. The intake of nutrients such as calcium and folate was as insufficient as below 75% of RI. The heme iron intake of the obese group was low that of the normal group(p<0.05). Among the major 20 iron resources the iron intake through animal food intake were 1.43 mg(12.00%) in the obese group and 1.93 mg(17.72%) in the normal group respectively. The rating of iron condition in the blood showed that the number of red blood cell(p<0.01), the hemoglobin(p<0.001), and hematocrit(p<0.01) of the obese group were lower than those of the normal group. These results suggest that there should be the right choice of food according to its bioavailability and nutritive guidance to appropriate food behavior, in addition to increasing iron intake to improve iron nutrition conditions of obese male elementary school students.
Although a generation-related difference in nutrient and food-group intake has been broadly recognized in the Japanese population, few studies have examined the difference and correlation of intakes with consideration of a family line and co-habitation status. We conducted a dietary survey using female college students in dietetic course in Aichi, Japan, and their mothers and grandmothers. A validated self-administered diet history questionnaire was used for assessment of intakes. Data from 110 families were included in the analysis. The means of 13 nutrients and 10 food groups (of the 15 and 14, respectively) showed significant differences among the three generations. A significant difference was observed in the carbohydrate, protein, saturated fatty acid, cholesterol, and fish intakes between the students living with their mothers and those apart. In the correlation analyses between generations, moderate correlation was observed for most nutrients and food groups between the students and their mothers living together (correlation range = 0.30-0.61 for nutrients, and = 0.21 -0.56 for food groups). A wide variation with no consistency was observed for the correlation between the students and their grandmothers (-0.18 -0.59 and -0.33 -0.65, respectively), No meaningful correlation was observed between any two generations living apart. Among the food groups examined, pulses, fish, and vegetables showed relatively large differences for the correlation between two groups with different living conditions. When living together, the correlation coefficients for nutrients and food groups between the students and their mothers decreased according to the increase in frequency of eating out by the students. These results suggest that living together and eating together were an important factor for the resemblance in dietary habits between generations in the population with a marked generation-related difference in intakes.

[Purpose] Effective nutritional intervention can help reduce the risk of nutritional problems and improve athletic performance in adolescents. The five A's (assess, advise, agree, assist, and arrange) model is widely used as the theoretical framework for advice on nutrition, smoking, drinking, and physical activity and it recommends that practitioners in primary health care promote behavior change to facilitate positive outcomes. This model has also been useful in understanding the underlying processes of behavior change. This study aimed to develop both a novel evidence-based nutritional intervention protocol, rooted in sound nutritional theory, and a customizable nutritional intervention program to support sustainable healthy eating, enhance nutrient intake, and improve athletic performance in adolescent athletes. [Methods] In this study, we adapted the 5 A's behavioral change model and motivational interview to develop a theoretical framework to help adolescent athletes change their behavior and achieve their goals. [Results] During each step of the 5 A's protocol, a customized nutritional intervention protocol was developed by nutrition experts for each of adolescent athletes. Each plan was developed to improve the eating habits of adolescent athletes through group education and counseling. All nutritional counseling sessions were designed to enable participants to apply nutritional knowledge and practical action plans to their training and competition conditions to enable each of them to achieve individual athletic goals and facilitate self-management. [Conclusion] A theoretical and evidence-based nutritional intervention protocol was developed to identify and address obstacles to healthy dietary habits in adolescent athletes. This could be used as the basis for further studies aimed at improving nutrient intake and athletic performance in adolescent athletes.

Objective: This experiment aimed to investigate the effect of different sources and inclusion levels of dietary fat on productive performance and egg quality in laying hens raised under hot environmental conditions. Methods: A total of 480 Hy-Line Brown laying hens at 31 wk of age were randomly allotted to 1 of 5 experimental diets. The control diet contained 2,800 kcal/kg nitrogen-corrected apparent metabolizable energy with no fat addition. Four additional diets were prepared by adding 2.0% or 4.0% of animal fat (AF) or soybean oil (SO). Energy and nutrient concentrations were consistent among all diets. Diets were fed to hens for 4 weeks. Average daily room temperature and humidity were $26.7^{\circ}C{\pm}1.52^{\circ}C$ and $77.4%{\pm}4.50%$. The heat stress index was approximately 76, indicating that hens were raised under heat stress conditions. Results: Final body weight (BW) was greater (p<0.05) for hens fed diets containing 2.0% or 4.0% AF than for those fed the control diet or diets containing 2.0% or 4.0% SO. The BW gain and feed intake were greater (p<0.05) for hens fed diets containing additional AF or SO than those fed the control diet. Eggshell thickness was the greatest (p<0.05) for hens fed the control diet, but the least (p<0.05) for hens fed diets containing 4.0% SO. Egg yolk color was the greatest (p<0.05) for hens fed the control diet, but the least (p<0.05) for hens fed diets containing 4.0% SO. Conclusion: Inclusion of supplemental fat (AF and SO) in diets exhibits preventative effects on BW loss for hens raised under hot environmental conditions when energy and nutrient concentrations in diets were maintained. The effects were greater for AF than for SO. However, inclusion of supplemental fat in diets decreases eggshell thickness and egg yolk yellowness, possibly due to a reduction in Ca absorption and intake of egg yolk colorants.

The purpose of this study is to provide preliminary data for bone disease prevention by examining the correlation between bone mineral density, and lifestyle and nutritional status of female shift workers, at general hospitals with an irregular life cycle. The subjects for this study were 232 female shift workers, over 30 years old, who worked at a general hospital more than 5 years. From the subjects, who understood the purpose of this study and decided to be participated, we measured serum albumin, total brotein, total cholesterol, hematocrit, hemoglobin, calcium, phosphorus from blood test, and obtained bone mineral density. To analyze the effectiveness of the variables for explanation power, we established the studied values as independent variables, bone minral density as a dependent variable. Exercise, the number of drinking, calcium, and phosphorus were selected as significant variables and the explanation power was 10.2%. The bone mineral density were significantly higher at the subjects who had exercise, higher calcium and phosphorus possession, and drank alcohol than the opposite cases. Regular exercise, and 1:1 intake of calcium and phosphorous were important to prevent osteoporosis for the subjects who were working three shifts which cause irregular lifestyle.

The purpose of this study was to examine dietary habits and nutrient intakes according to feeding method during infant period in elementary school students. Subjects were 1,251 elementary school students. Subjects were divided into three groups, breast-fed group (N=508), formula-fed group (N=397), and mixed group (N=346), according to feeding method during infant period. The questionnaire was composed of general characteristics, dietary conditions during infant period, dietary behaviors, and dietary intakes and was completed by children and children's parents. Average age, height, weight, and body mass index were 11.6 years, 139.0 cm, 34.6 kg, and $17.8kg/m^2$, respectively. The formula-fed group showed a smaller proportion of subjects with colostrum feeding (P<0.001) compared to the breast-fed and mixed groups. Frequency of eating snacks was significantly higher in the mixed group than in other groups (P<0.05). There was no significant difference in dietary habit total score and nutrient intakes according to feeding method during infant period. Feeding method in during infant period was associated with dietary habits (milk and vegetable intake habits) up to growth period of elementary school. A longitudinal and systematic study is needed to clarify this relationship.

The current study was conducted to evaluate the effect of calcium-enriched fatty acid supplementation on the growth performance, blood metabolites, intestinal morphology, carcass traits, and nutrient digestibility of broilers subjected to chronic heat stress. A total of 210 one-day-old broiler chicks (40.12 ± 0.25 g) were randomly allocated to one of five dietary treatments, to obtain six replicates per treatment. Broilers were subjected to chronic heat stress from day 21 to day 35, post-hatching, at 34℃ for 9 h per day. The body weight (BW) and feed intake of the experimental broilers were recorded weekly, and the average daily gain (ADG) and feed conversion ratio (FCR) were calculated accordingly. Rectal temperature was measured to compare the basal body temperatures between individuals, and blood samples were collected on days 21 and 35 to evaluate basal body temperature, serum total cholesterol, and the triglyceride content of the broilers. On days 21 and 35, one broiler from each cage (n=6) was euthanized to measure carcass trait parameters, nutrient digestibility in digesta, and intestinal morphology. On days 14, 28, and 35, the broilers fed 2.0% calcium-enriched fatty acids had higher BW (p < 0.05) than those fed the other diets. However, no differences (p > 0.05) were found in the average daily feed intake (ADFI) between dietary treatments over the 35 experimental days. On the other hand, on day 21, post-hatching, the broilers fed the 2.0% calcium-enriched fatty acid diet had improved (p < 0.05) dietary feed efficiencies compared to the other treatments. On day 28, the broilers fed the 5.0% of calcium-enriched fatty acid diet also had higher (p < 0.05) dietary feed efficiencies than those fed with the other dietary treatments. No effects (p > 0.05) on carcass weight, nutrient digestibility, intestinal morphology, or blood parameters were found between broilers fed with dietary treatments. This study demonstrated that the inclusion of an additive, containing 2.0% calcium-enriched fatty acid, to broiler diet could ameliorate the negative growth performance of broilers; and no interaction (p > 0.05) was observed between the calcium-enriched fatty acid and nutrient digestibility, digestive anatomy, blood metabolism, and carcass traits of broilers subjected to chronic heat stress conditions for 35 days post-hatching.
The elderly often experience difficulty while eating; this can include physical problems, such as chewing and swallowing. Furthermore, their salt intake can be high due to a diminished sense of taste and smell. This can result in a reduction in calorie intake and subsequent malnourishment. Currently, the number of food products available in the market that are targeted specifically at the older population is very low. Development of nutritional supplement-based foods for the elderly is expected to reduce these dietary problems and therefore prevent nutritional deficiencies within this population. Milk and other dairy products are excellent sources of nutrition in terms of both nutrient content and absorption rates. Dairy products have been consumed around the world for centuries, and therefore represent an excellent food source for the elderly. In addition, use of milk-derived ingredients, such as casein and calcium, will enable the development of a variety of food products and supplements targeted at this specific age group. In the future, it is expected that milk and other dairy products will be used to develop a variety of nutritious food items for the elderly in the domestic food market.
Investigation of foodservices was carried out in 7 different day care centers in Gyeongnam area and no trition survey of their 481 children were undertaken between October 5 and November 3, 1994. The results were summarized as follows: Conditions of most equipments and facilities used in the kitchen were very defective especially in dishwashing and sterilizing step. Number of cooks and assistant cooks in foodservices was 1 or 2. Purchasing of foods and planning of menu were mainly done by the manager or the secretary. Menu was cycled weekly. None of the day care centers has empolyed a dietitian. Mean values of height and weight of children showed slightly over the standard of Korean children. Mean intakes of energy and all the nutrients from the lunch, which was served by day care centers, were below 30% of the Korean RDAs. Mean value of protein, thiamine and niacin were above 25% of the RDAs. Intakes of Ca, Fe and Riboflavin were lower than the ones of other nutrients. It is suggested that dietitians should be empolyed to take care of meal services and nutrition education for the children.
Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.
