This study was aimed at comparing the dietary pattern of middle school girls according to family type. As for subjects, sixty girls of M middle school of Taejon city were chosen as a total. They were devided into two groups consisted of thirty subjects respectively ; those who live in single mother's family(SMF) and both parent's family(BPF). In this study, intakes of food and nutrient and dietary behaviors of each group were investigated through two-day dietary records and questionnaire. The results obtained in this study were as follows : 1) Mean daily intake of all nuitrients except calcium were more than RDAs in two groups. However, intake of calcium and rtio of Ca / P were lower than RDAs in two groups. And proportion of less than 2/3 of RDAs of calcium were higher than other nutrients. Intake of iron was more than RDAs, but nutritional status of iron might be poorer considering the food sorce of iron taken by subjects. According to family type, girls of SMF seemed to have more serious to have more serious problem in these nutrients than those of BPF. 2) The average distribution ratios of breakfast, lunch, dinner and snack to total calorie intake was 25.2, 31.3, 24.6 and 18.9 in SMF, and 19.7, 33.1, 24.3 and 22.9 in BPF. Thus it proved that lunch contributed more energy intake than any other meal, and that snack was an important means to supply nutrients for girls of two groups. And energy intake through breakfast of SMF was more than BPF. 3) The major dietary problems of two groups were unbalanced diet, missing meal, and overeating. The degree of sharing meal with family was lower in girls of SMF than those of BPF. The degrees of skipping (p<0.05), or irregularity, or preparing meal by girls(P<0.05) in the case of dinner were tended to be more frequent in SMF than BPF. And number of food taken per day was less various in SMF of 15.2 kinds than BPF of 17.1 kinds(P<0.001). As a conclusion, subjects should take more calcium or iron contained food which is well absorved, and eat diverse foods to improve their nutritional status. And it is also necessary that calorie intake through snack should be diminished, and dinner should be eaten regularly and shared with family if possible. In view of family type, girls of SMF proved to have poorer food habit than those of BPF. Thus, these results shows that dietary pattern of girls is different atcording to family type. Therefore, we should carry out nutritional education for girls considering the difference of dietary pattern by family type. In addition, nutritional education for girls of SMF should be regarded more importantly than those of BPF because girls of SMF might have more chance to manage their meal by themselves and also have more dietary problems.

This nutritional survey was conducted from September 17 to October 6, 1984, in order to investigate the state of the nutritional intakes of perple living Gapoe-Dong, coastal area of Korea. This survey covered a total of forty houses. The method of this research was based on the interiview-survey with questinaires. All of the food taken daily by the people are all weighed before cooking ; the rest of food after mealing are also weighed. Thus the amount of food taken by people can be come out. The results were summarized as follows; 1) The average intake of all nutrients were below the RDA, especially calorie, vitamin B2, calcium and iron were insufficient. The protein intake was only 55.2g but the contribution of animal protein to total protein was adequate(38%). It was provided mostly by fish and shell-fish. 2) Chief food sources were rice, vegetables, fish and shell-fish, and milk, eggs, oil, potato, and fruits were insufficient. 3) The level of education and the number of family were significantly correlated to the nutrientintake, especially correlation between family-size and colorie, calcium intake were significant.

This study was performed to investigate the relationship between milk consumption, dietary nutrient intake, and physical strength in Korean adolescents for dietary education of home economics subject at middle and high schools. Intake of milk and milk products, that of dietary nutrients, and physical strength records were surveyed for 298 high school students resided in small and medium-sized cities in Korea. Intake of milk and milk products was collected from three-day dietary survey, and daily dairy equivalent of calcium was calculated by dividing daily calcium intake(mg) from milk and milk products by calcium content(200 mg) of 200 mL milk. Dietary survey was performed during three days including two-weekdays and one-weekend by food record method. Dietary nutrient intake was analyzed by CAN-Pro 3.0. Physical strength records were offered from subjects' schools. Subjects were divided into low intake group(${\leq}0.29/d$), medium intake group(0.30-0.78/d) and high intake group(0.79-5.66/d) according to daily mean dairy equivalent of calcium taken by them, and most of them consumed milk and milk products less than '2' of the recommended value. Daily mean dairy equivalent of calcium was significantly related with high records of '50 m running' and 'stand long jump'(p<0.05), however it was not related with other records of physical strength. Intakes of energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, thiamin, riboflavin, niacin and vitamin E were significantly correlated with high record of '50 m running'(p<0.01). Intakes of nutrients were related with '50 m running' except fat were significantly correlated with high record of 'stand long jump'(p<0.05). Intakes of protein, phosphorus, iron, zinc, vitamin A, $B_6$ and E were significantly correlated with high record of 'long distance running'(p<0.05). In conclusion intake of milk and milk products was related with physical strength records('50 m running' and 'stand long jump') and intakes of most nutrients including energy nutrient, vitamin and mineral were correlated with physical strength records('50 m running', 'stand long jump' and 'long distance running') in Korean adolescents. Therefore, optimal consumption of milk and various nutrients for balanced nutrition during adolescents should be emphasized in dietary education of home economics subject for their strong physical strength.

Within the elderly population, the use of calcium supplements and the intake of calcium from food are on the rise in order to maintain health. Calcium is absorbed as an ion in vivo, leading to speculation that absorption efficiency is affected by the solubility of the calcium consumed. In our study, the bioavailability of two types of calcium supplements with different solubilities was evaluated. Experimental animals were fed water-soluble or insoluble calcium supplements for 6 weeks. We found that blood alkali phosphatase activity, osteocalcin content, and urine crosslinks values were not different between the groups. Similarly, the degree of apparent calcium absorption between the two calcium supplements was not significantly different. The bone mineral density and bone mineral content of the femur and the tibia increased in the group that consumed insoluble calcium compared with those of the water-soluble calcium supplemented group. However, when considering body weight, the bone mineral density value for all areas, including the spine, was significantly higher in the group that consumed the water-soluble calcium supplement.

This study investigated dietary behavior and nutrient intake in children with developmental disorders as compared with non-disabled children and assessed the relationship between dietary behavior and nutrient intake. The survey was conducted on 118 students ($4^{th}$ and $5^{th}$ grade) of four special education schools and 244 students of an elementary school (control group). The survey was carried out using a questionnaire and an interview. Of the disabled children, children with a mental disorder comprised 72.9% and those with emotional disorders including autism comprised 26.3%. The average percentages of height and weight to standards for age were significantly lower in the disabled female children as compared with the non-disabled female children. Scores for table utensil handling skills, eating behavior, and an unbalanced diet were lower in the disabled children compared with those in the non-disabled children. Dietary behavior scores were not significantly different by either gender or age in the disabled children. Mean energy intake was less than the estimated energy requirement in both groups. Nutrients taken at less than the recommended intake level were calcium, iron, vitamin A, and folate in both groups. Food behavior score at mealtime, personal hygiene score at mealtime, and an unbalanced diet score were significantly correlated with iron and vitamin A intake in disabled male children. Personal hygiene score at mealtime was significantly correlated with calcium, iron, and vitamin A intake, and unbalanced diet score was significantly correlated with iron and vitamin A intake in disabled female children. Although the nutritional status of disabled children with developmental disorders was appropriate in general, improvement in their dietary behaviors through education and practice would allow them to eat balanced diets with essential nutrients.

The purposes of this study were to assess dietary intake obtained by easy method and to compare dietary behavior of house wife and female college students in Yanbian. The subjects consisted of 276 house wives and 228 female college students. Mean daily energy intake of house wives was 1926.0kcal and that of female college students was 1949.0kcal. Calcium intake as NAR(Nutrient adequacy ratio) was lowest in house wife and female college student. Iron intake was also low in subjects and lower in female college student than in house wife. Meal frequency per day was regular in subjects. Skipping meal time in subjects was breakfast and snaking time was late evening generally. Frequency of eating out was rare in most subjects and 60.6% of subjects preferred chinese food in eating out, while house wives preferred Korean food than female college student in eating out. The vegetables were preferred than meat or fish and used by fried in sauces. Hot and sour tastes were more like than greasy taste in subjects. Nutrient intake levels and dietary behaviors of house wife were to be like as those of female college students in general. BMI(Body mass index) was lower in female collage students than house wives, similarly in Korean. According to these results, house wives and female college students in Yanbian had similar dietary patterns. Calcium intake was tend to be low and dietary pattern was regular, dietary qualifies of subjects were adequate. Nutrient intake and dietary pattern in Yanbian were to be like as in Korean, and the Korean-Chinese in Yanbian maintained traditional dietary pattern.

BACKGROUND/OBJECTIVES: Vitamin D plays an important role in skeletal growth and maintenance and in the prevention of various diseases. We investigated the relationship between vitamin D intake and bone mineral density (BMD) in Korean adults aged ${\geq}50$ years using the 2009 Korea National Health and Nutrition Examination Survey data. SUBJECTS/METHODS: This study was conducted in 1,808 subjects aged ${\geq}50$ years with BMD data in Korea. Dietary vitamin D levels were assessed by the 24-hour recall method. BMD was measured using dual-energy X-ray absorptiometry. We investigated general characteristics and the association between these characteristics, vitamin D status, and BMD. RESULTS: Vitamin D intake was significantly lower in the osteoporosis group among women (P < 0.05). Among all subjects, the higher the serum 25(OH)D concentration, the higher the whole-body total BMD (WBT-BMD), femoral total hip BMD, and femoral neck BMD (P < 0.01). In the serum vitamin D-deficient group of both the total population and women, serum 25(OH)D concentration was associated with WBT-BMD (P < 0.05). Among women with a calcium intake < 537.74 mg/day, BMD of those with a vitamin D intake > $2.51{\mu}g/day$ (average intake of women) was higher than that of women with a vitamin D intake ${\leq}2.51{\mu}g/day$ (P < 0.001). CONCLUSIONS: Korean adults should increase their BMD by increasing serum 25(OH)D concentration. Furthermore, increasing vitamin D intake could improve BMD, especially in Korean women who consume less calcium than the estimated average requirement.

To assess the nutrient intakes and diet quality of middle school students living in Kangneung area a dietary survey using th 3-day food record was conducted with 226 subjects. Mean daily energy intake was 2114$\pm$502 kcal with 61.6% of energy supplied by carbohydrate 16.4% by protein and 22.0% by fat. As well as insufficiencies in calcium and iron intakes the bioavailability of calcium and iron consumed is considered to low because most of them came from plant origins. For calcium iron vitamin A and vitamin B$_2$the proportions of subjects with intake levels less than 75% of RDA were all over 46%. The mean adequacy ratio(MAR) an index of overall dietary quality was 0.70 for males and 0.73 for females. The indexes of nutritional quality (INQ) were over 1 for most nutrients except 4 nutrients; 0.48 of calcium 0.64 of iron 0.73 of vitamin A and 0.79 of vitamin B$_2$. Nutrient intake levels less than 75% of RDA may be appropriate as a criteria for insufficiency of nutrient intakes. Based on these results it is evident that some of middle school students in Kangneung area did not consume enough nutrients especially calcium iron and vitamin A.

The Purpose of this study was to investigate the dietary intake of nutrients and the use of vitamin and mineral supplements by Korean college students attending Web class and the socioeconomic, dietary and health-related factors involved. The subjects were 137 male and 115 female students amending a health and nutrition-related Web class at a cycler university. This cross-sectional survey was conducted by self-administered questionnaire and the data were analyzed by SAS and SPSS PC package programs. Nutrient intake data collected using three-day recall method were analyzed by the Computer Aided Nutritional Analysis Program. Average intake by male students of most nutrients except energy, vitamin B$_2$ and calcium and intake by female students of those except energy, vitamin $B_2$, calcium and iron was higher than Korean RDA. Nutrient intake of male students was significantly influenced by the mother s job, skipping meals, exercise, vitamin and mineral supplement use, flood supplement use and self-evaluated anemia. Skipping meals and flood supplement use significantly influenced the nutrient intake of female students. A total of 47.4% of male students and 53.9% of female students were vitamin and mineral supplement users. In female students, socioeconomic characteristics such as the father s education level and household income were significantly different between vitamin and mineral supplement users and non-users. In both male and female students, there were significant differences in cross analysis between vitamin and mineral supplement use and flood supplement use. As for the self-reported health status of male and female students, vitamin and mineral supplement users perceived their health status to be worse compared to non-users. Therefore, nutrition education via the Internet is necessary in order to encourage college students to practice optimal nutrition strategies, including maintaining well-balanced diets by choosing various floods wisely.

In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.
