This study was carried out to compare the dietary behaviors and the nutrient intake of a middle school and a high school girls in Iksan. The subjects consisted of 132 middle school girls and 122 high school girls in Iksan. The proportion of subjects eating meals irregularly was higher in the high school girls (98.6%) than in the middle school girls(78.7%). The proportion of subjects skipping a meal also was higher in the high school girls(61.5%) than in the middle school girls(53.8%) and most of them (65.8%) skipped breakfast though they thought breakfast was the most important meal of a day (87.4%). The subjects tended to overeat at lunch (38.6%), and at dinner (55.9%). The main reasons of skipping a meal were 1. They had no time (49.3%), and 2. They had poor appetite (24.7%) Mean daily energy intake was 2198.5Kcal in the middle school girls and 2150.5Kcal in the high school girls and mean daily intake of protein, iron, vitamin $B_1$, vitamin $B_2$ and niacin was significantly higher (p<0.05, p<0.01) in the middle school girls than in the high school girls. Mean daily calcium, iron, vitamin $B_1$, vitamin A and C intake of middle school girls were lower than those of RDA and all nutrients intake of high school girls except for phosphorus was lower than those of RDA. The index of nutritional quality (INQ) was under 1.0 for calcium, iron, vitamin A, $B_1$ and C. Mean blood level of cholesterol, triglyceride, Hb, Hct, GOT, GPT were 170.9mg/dl, 78.9mg/dl, 13.1g/dl, 39.5%, 18.8mg/d and 15.7mg/dl, respectively.

This study was conducted to provide insight into the management and care of the elderly in nursing homes. Eighty-six elderly subjects over 65 years old (38 male, 48 female) in 3 non-fee-paying nursing homes, located in Daejeon and Chungchong areas, were studied. Subjects'dietary intakes by estimated food intake records, and self-perceived health conditions, were studied using questionnaires from July 21 to August 1, 1997. Twenty-one % of the male subjects and 42% of the female subjects were over 80 years. Their predominant past occupation was farming. While 8.3% of the female and no male residents showed a BMI (Body Mass Index) of 27 and above, about 30% of the subjects were underweight and in poor health status in seeing, joint pains, lumbago and shoulder pains. Regarding overall health status, 72.1% of the subjects considered them to be in poor health, and female and male subjects suffered more difficulties from cloudy eyes, joint pains and lumbago and shoulder pains than any other. Neuralgia was the predominant chronic complaint and followed by hypertension in both sexes. Overall, female subjects felt worse off than the male subjects in terms of their health status, that can be attributed to higher average age of the female subjects compared to the male subjects. The elderly were eating a very low fat (about 15 g : 6% of total calorie) diet with low vitamin A and E. Intakes of calories, protein and iron slightly exceeded RDA. The phosphorus intake was more than double the RDA although calcium intake was close to the RDA. From these results, it seems important to doubling the fat intake of the elderly residents in the form of vegetable fat with the object of raising of vitamin E, antioxidant vitamin, and essential fatty acids for the elderly. It is also recommended that the elderly residents should be given adequate calcium and exercise for bone health.

Calcium is an essential nutrient for living organisms, with key structural and signaling roles. Its deficiency in plants can result in poor biotic and abiotic stress tolerance as well as reduced crop quality and yield. Calcium deficiency in humans causes various diseases such as osteoporosis and rickets. Biofortification of calcium in various food crops has been suggested as an economic and environmentally advantageous method to enhance human intake of calcium. Recent efforts to increase the levels of calcium in food crops have used calcium/proton antiporters ($CAXs$) and modified one to increase calcium transport into vacuoles through genetic engineering. It has been reported that overall calcium content of transgenic plants has been increased in their edible portions with some adverse effects. In conclusion, biofortification of calcium will add more value in crops as well as will be beneficial for animal and human. Therefore, more fundamental studies on the mechanisms of calcium ion storage and transporting are essential for more effective calcium biofortification.

This study evaluated the effect of nutritional improvement of 0~5 year children of financially poor families after nutrition supplement of children and nutrition education in parents/guardians. The subject selected among applicants for low-income family financing of the government included 198 children (0~12 months:92, 1~5 years:106), and the average ages were 5.3 months and 2.4 years respectively. Food that includes each nutrient factor was provided to the subject for six months. Nutrition education was performed in two ways, through class and private education, once a month for both. Nutritional improvement was evaluated by body measurement and anemia prevalence rate. As to the survey on breast-feeding, complete breast-feeding accounted for 58.7%, weaning food 27.3%, and combined feeding 14.1% respectively, which shows that breast-feeding accounted for the largest percentage. The education program improved knowledge and attitude of the parents/guardians, which brings in positive effects on growth of children as well. The nutrition knowledge score was improved after nutrition education in 0~12 month children $(8.5\pm1.75\;to\;8.9\pm1.69)$ and 1~5 year children $(7.3\pm1.39\;to\;7.8\pm1.30)$. The nutrition attitude score was significantly improved in 0~12month children $(52.0\pm6.99$ to $53.5\pm5.21$, p < 0.001) and 1~5year children ($45.1\pm7.30$ to $49.0\pm5.96$, p < 0.001). In evaluation on nutritional improvement based on body measurements, it turned out that the wasting was reduced as for children in consideration of the height and weight according to the subject's age. The concentration of hemoglobin after the nutrient treatment for six months was significantly improved, and the anemia prevalence rate as well was reduced from 40.6% to 13.5%, which indicates the significant improvement. Based on the findings above, it turned out that providing quality food to children and nutrition education to the parents/guardians poorly fed in low-income families improved knowledge and attitude of the guardians and prevents anemia and improves growth, which brings in positive effects on growth of children. In the results regarding attitude and knowledge on nutrient/dietary life; however, the improvement level was relatively low when the extent before the education was too small, which indicates the need to revise and complement the contents and methods. In addition, as shown in the result of body measurement, long-term and consistent investigation is necessary since it is difficult to judge the effect on growth only based on short-term nutrient supplement.

The present study was conducted to document North Korea's long standing food shortage situation and to evaluate the devastating effects of its recent food crisis on the already poor health and nutritional state of the people in North Korea. We analyzed the mail survey data on food consumption patterns and anthropometry of 109 North Korean defectors, male, aged 20 years and older, who resettled in the South during the period of 1988-1999. The result of our survey data indicated that during 1988-1993 when North Korea's food supply was not yet emerged as a serious problem, food and nutrient intake of North Korean defectors was estimated to be significantly lower that the recommended intake levels for maintenance. Energy and protein intake of subjects who defected further with the recent food crisis. For subjects who defected after 1994, the total and animal food intakes were reduced to 67% and 25%, respectively, of the amounts consumed by those who defected in the period of 1988-1993, and their energy and protein intake was decreased by 27% and 30% to the level of 1,181kcal and 40g. Regardless of the time of defection, the mean height and body weight of defectors was significantly lower than that of South Korean reference men. The prevalence of infectious diseases and malnutrition signs was higher among defectors who resettled in the South after 1994 compared to those who resettled during 1988-1993.

Poor dietary habits and inadequate nutrient intakes are of concern in the elderly, even it is worse in rural areas. In the present study, we conducted the anthropometric measurement and the dietary intakes including macronutrients, minerals and vitamins to assess the nutrient intakes and nutritional risk in elderly people in rural kyungpook province in South Korea. Subjects (n = 168, mean age, 67.3 yrs) were interviewed using d general questionnaire and 3 days of 24-hours recall for dietary intake. Nutrient intakes were analyzed using CAN-pro soft program and compared to Korean RDA and nutrition reference values (NRV). The anthropometric measurement showed that the weight and the height of the subjects in the rural area were below the average of the same age of Korean elderly people. The energy and protein intakes were 85％ and 90％ of Korean RDA, respectively. The intakes of lipid, cholesterol and dietary fiber were 62％, 40％ and 22％ of NRV for Korean adults. Main sources for protein and lipid intakes came from the vegetable sources and this pattern was more prominent in female elderly people. Ca intake was half of Korean RDA (56％), while P intake was 132％ of Korean RDA. For the antioxidant trace mineral (Fe, Cu, Mn, Zn, and Se) intakes, Fe and Zn intakes were 78％ and > 103％ of Korean RDA. Cu, Mn and Se intakes were > 113％, > 275％, and > 185％ of Korean NRV. Thiamin, niacin and vitamin C intakes were above Korean RDA, but the intakes of vitamin A and riboflavin were 88％ and 63％ of Korean RDA, respectively. On summarizing the results of the present study, the elderly people in rural area consume less lipid, cholesterol, Ca, and dietary fiber. Ca intake is lower, while P intake is higher, and this would be the potential risk for bone health. Also, Na intake was high, which can be the potential risk for the cardiovascular disease prevailance. Vitamin intakes were fairly good status, excepting riboflavin. Antioxidant mineral intakes were much higher than Korean NRV, unexpectedly. The results suggest that the elderly people in rural area have inadequate intakes of protein, lipid, dietary fiber and Ca, which mainly should be supplied from animal products. Recommendations to increase diet variety would be emphasized for this nutritionally poor-conditioned subjects, specially including animal food products and high dietary fiber food.

BACKGROUND/OBJECTIVES: Chewing difficulty is a factor contributing to a poor nutritional status in the elderly. The aim of this study was to examine disparities in food and nutrition intakes among Korean elderly people with and without chewing difficulty. SUBJECTS/METHODS: This study utilized data from the sixth Korea National Health and Nutrition Examination Survey conducted in 2013. The study subjects included males and females over 65 years of age who were not required to adhere to a special diet due to disease or sickness. They were divided into groups according to their chewing ability. Those who found chewing "very difficult" or "difficult", were combined to form the chewing difficulty group. Similarly, those who found chewing "moderately difficult", "easy", and "very easy" were combined to form the normal chewing group. RESULTS: Of the 999 subjects, 47.7% had chewing difficulties and the prevalence of chewing difficulty was higher in females than in males (P = 0.03) and higher in those 75 years of age and over than in younger individuals (P < 0.001). The chewing difficulty group had a significantly lower intake of fruits and vegetables (P < 0.05) and lower vitamin C and potassium intake than those in the normal group. Comparison of the percentages of Dietary Reference Intakes for Koreans (KDRIs) in the two groups indicated that the intake of most nutrients (energy, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, sodium, potassium, and iron) were significantly lower in the chewing difficulty group than in the normal group. In particular, calcium intake was inadequate (51% of KDRIs) in the chewing difficulty group. CONCLUSIONS: The results indicate that chewing difficulty is closely related to food and nutrient intake in the elderly and can result in vitamin and mineral intake deficiencies. It is evident that the care of elderly subjects with chewing difficulty is essential for maintaining a healthy lifestyle.

The purpose of this study was to compare the awareness of dietary patterns and health of full-time and employed housewives. The investigation gathered information on general characteristics, dietary lifestyle, nutritional status, and health by questionnaire as well as anthropometric measurements. The subjects included housewives living in Seoul and Gyeonggi Province (86 full-time and 127 working housewives) during November 2009 to January 2010. The average age, height, and weight of the housewives were $45.8{\pm}7.6\;yr$, $161.0{\pm}8.4\;cm$, and $55.7{\pm}6.3\;kg$, respectively. The average monthly income of the households was 3 million to 5 million won (31.4% full-time and 37.0% working housewives), and their average food expense was 200,000 to 500,000 won (46.5% full-time and 48.1% working housewives). More than 90% of the studied homes were nuclear families and the most common number of children was 2 to 3 (79.1% full-time and 76.4% working housewives). The ratio of employed housewives who ate regular meals was 35.4%, but that of the full-time housewives was 48.2% (p<0.05). Of the working housewives, 7.1% never ate breakfast and the primary reason for skipping breakfast was 'busy in the morning' (61.1%). The type of food that the housewives preferred when eating out was Korean food, both for the full-time and employed housewives (76.0%). All the housewives overate calories and the full-time housewives ate more protein, fat, vitamin A, vitamin B1, vitamin B6, niacin, vitamin C, vitamin E, folic acid, and cholesterol than the employed housewives (p<0.05). Both the full-time and employed housewives were more satisfied with supper than with other meals. About 30.6% of the full-time and 33.9% of the working housewives had no interest in health, but answered that regular exercise was very important for health (33.3% full-time and 39.7% working housewives). In conclusion, working housewives have poor dietary habits and nutrient intakes, thus substantial measures to improve these problems are urgently needed.

In recent years, the number and proportion of Korean elderly have grown rapidly, and elderly individuals show a disproportionate risk for poor nutritional status. The purpose of this study was to examine the relationship of sociodemographic background to nutrient intake of persons 65 years of age or older, living in 15 cities in Korea. Data on 1973 subjects (603 males, 1370 females), who participated in the Korean Elderly Nutrition Survey (2000), were analyzed. Their mean age was 72.3 years and their mean body mass index (BMI) was 24.2 kg/$m^2$. Basic sociodemographic data were obtained through personal interviews. The 98-item semi-food frequency questionnaire, developed and previously validated for Korean middle-aged and elderly subjects, was administered. “Percentage of subjects who consumed under 75％ Korean RDA,” “number of nutrients consumed below 75％ Korean RDA,” “mean nutrient adequacy ratio,” and “nutrient density” were used to determine nutritional status. Male elderly had better nutritional quality than female elderly. Nutritional quality decreased with age, especially in older elderly (over 75). Elderly who were underweight (BMI 〈 20 kg/$m^2$) showed poorer nutritional quality than those who were normal weight (BMI 20∼25 kg/$m^2$) and overweight (BMI $\geq$ 25 kg/$m^2$). Elderly who lived alone had significantly poorer nutritional quality than those who lived with a spouse, and/or with children. Lower education level and economic dependence also showed lower nutritional quality. A stepwise multiple regression analysis was performed to examine the effects of specific sociodemographic factors on nutritional quality. For number of nutrients under 75％ RDA as a dependent variable, education level explained 4.8％ of the variance, followed by living status, age, body mass index, gender, and living expense support (Model $R^2$ = 0.091). For mean nutrient adequacy ratio as a dependent variable, model $R^2$ was 0.098. Therefore, sociodemographic variables such as gender, age, body mass index, living status, educational level, and economic status influenced elderly nutrition status. These results indicate that an elderly nutrition intervention should focus on subjects who are poorly educated, living alone, age 75 or older, and/or underweight.

This study was conducted to evaluate the nutritional status of elementary school lunch programs. The subjects of this study consisted of 170 elementary school students(male 51.8% : female 48.2%) in the 5th and 6th grades. The dietary intake of nutrients was assessed by the modified 24-hour recall method. The results are summarized as follows: the average body weight was 41.3$\pm$7.93kg for boys and 40.5$\pm$ 8.35kg for girls. The average height was 149.5$\pm$5.88cm for boys and 146.2$\pm$5.82cm for girls. The total daily energy and nutrient intake was below the RDA's except for the intake of niacin and ascorbic acid. School lunchs provided 31.5% of total energy intake ; 32.5% of carbohydrate intake, 31.9% of protein intake and 33.4% of fat intake. Therefore, school lunchs largely contributed to the nutritional balance of these children. The food habit score was poor for 40.6% of the subjects.
