The purpose of this study was to investigate the effects that body composition, nutrient intake, and biochemical indices have on skin status, as well as their associations with skin health status, by assessing 44 female university students. The subjects were classified into 3 groups according to skin sensitivity: sensitive skin (n=11), slightly sensitive skin (n=24), and normal skin (n=9). The study included anthropometric measurements and body composition analyses, dietary intake evaluations, blood chemical analyses, and skin health status assessments. Based on % body fat, the results indicated the subjects were moderately obese (29.6%). Obesity indices were not different among the groups, but the sensitive skin group tended to have higher skinfold thickness. Dry skin was determined as the skin type of all subjects. In the sensitive skin groups, U-zone and T-zone sebum were significantly lower (p〈0.05), and spots were significantly higher (p〈0.05) than in the normal skin group. In terms of nutrient intakes, the sensitive skin groups consumed significantly lower amounts of P and vitamins A and E (p〈0.05). There were no significant differences in serum lipid fractions or total antioxidant status among the groups. In correlation coefficients analysis, skin elasticity had significant negative correlations with subscapular and midaxillary skinfold thickness, body protein, and body minerals (p〈0.05). Wrinkling had positive correlations with triceps and thigh skinfold thickness (p〈0.05). Skin evenness had negative correlations with energy intake, vitamins A, B1, B2, C, E, niacin, and zinc (p〈0.05), as well as folate and P (p〈0.01) and vitamin B6 (p〈0.001). A similar correlation tendency was observed for spots and nutrient intake, showing negative correlations with vitamins A, B6, and E, as well as folate, Fe, and P. U-zone sebum showed significant positive correlations with serum levels of total cholesterol and triglycerides. From these findings, skin health status appears to be affected by both nutrient intake and body composition. Therefore, having a proper balance between dietary intake and body composition may influence skin health status in females with sensitive skin.

The purpose of this study was to obtain baseline data of nutritional management for women's bone health according to age. This study was conducted through questionnaire, bone mineral density(BMD) measurement by DEXA and dietary survey by 24hr recalls to 134 adult women. Subjects were divided into three groups: young women group who aged 20-29(n=48), middle aged women group who aged over 30 and were pre-menopause(n=36), postmenopausal women group(n=48). The body fat percent of postmenopausal women group was the highest among the three groups. BMD of lumbar spine(L1-L2) were 0.93 g/cm2 for young women, 0.97 g/cm2 for middle aged women, and 0.88 g/cm2 for postmenopausal women, respectively(p〈0.05). BMD of femoral neck(p〈0.05), trochanter(p〈0.05), and ward's (p〈0.001) were significantly decreased as age increasement. Drinking alcohol and skipping meals were significantly higher in young women groups than in the other groups, however frequency of doing regular exercise was significantly lower in young women groups. Young women group consumed the significantly higher amount of cereals(p〈0.05), sugar and sweeteners(p〈0.001), meats(p〈0.01), eggs(p〈0.01), milks(p〈0.05) and oils(p〈0.001) than middle aged and postmenopausal women. Also, energy(p〈0.001), animal protein, (p〈0.01), plant oil(p〈0.001), animal fat(p〈0.001), retinol(p〈0.001), vitamin E(p〈0.01), and cholesterol(p〈0.001) intakes of young women were highest among the three groups. However, young women group consumed the significantly lower amount of dietary fiber(p〈0.05), vitamin C(p〈0.01), folate(p〈0.05) and fruits(p〈0.01) than the other groups. To summarized the our results, young women who were in still undergoing bone formation activity to develope peak bone mass, had more dietary habit and lifestyle problems than middle aged and postmenopausal women. The results of this study revealed that nutritional management and education for bone health should be emphasized in young women not only aged women.

The purpose of this study were to investigate middle and high school students' food habits and food attitudes, and to assess student's nutrient consumption. A self-administered questionnaire was developed based on review of literature. The questionnaire consisted of three sections (food habits, food attitudes, and food consumption). The questionnaires were distributed to 4,050 students enrolled in 34 middle and high schools located in Seoul, Gyeonggi, and Gyeongnam provinces. A final response rate was 88.2% (3,570) excluding responses that had significant missing data. Data of the food habits and food attitudes were analyzed with descriptive analysis, 2-test, and t-test using SPSS WIN(ver.11.0). The student's self-reported food consumption data was converted into nutrient consumption using conversion factor. Many middle and high school students skipped breakfast and/or dinner. Approximately 29% of the students did not eat vegetables and fruits. Scores of the middle school student's attitudes(19.1) towards foods were significantly higher than those of the high school student's attitudes(18.7)(p〈.001). Student's nutrient intakes were estimated according to the student's self-reported food consumption data. The nutrient intakes were compared with DRIs(Dietary Reference Intakes: DRIs) for their age groups. The result of EAR(Estimated Average Requirement: EAR) cut-point method demonstrated 57.7% of middle school boys, 64.4% of middle school girls, 70.2% of high school boys, and 71.0% of high school girls did not meet EAR for Calcium. Additionally, it showed that 39.0% of middle school boys, 23.7% of middle school girls, 58.4% of high school boys, and 24.4% of high school girls did not consume EAR for Vitamin B1. 25.7% of middle school boys did not meet EAR for Vitamin B2, while 44.4% high school boys did not satisfy EAR for Vitamin B2.

To evaluate the effect of cereal supplementation on children's iron nutritional status of Korean institutionalized was designed. Dietary survey was carried out methods of food weighting in the breakfast or/and dinner, and record interview in lunch (n=74). A nutritional intervention study was carried out through supplementing cereal for 4 weeks in 24 children of 1 institution from 4 to 12 years. The children received 3.6mg elemental Fe(as 100g cereal) per day. Blood samples were drawn before and after supplementation. Nutrients which children's intake was less than two-thirds of Korean RDA were Vit A, Vit B1, Vit B2, Ca and Fe. The mean daily intakes of iron were 5.1mg for male and 4.9mg for female and 52.3% for male and 45.4% for female of Korean RDA. The proportions of children with iron depletion assessed by TIBC(>360mg/dl) and serum ferritin(<20ng/ml) were 56.6% and 58.7%, respectively. The proportions of children with the iron deficient erythropoiesis assessed by serum iron(<70ml/dl), Hb(<12g/dl), and Hct(<36%) were 76.0%, 58.7%, and 64.0%, respectively. After cereal supplementation, in anemic children, levels of Hct(p<0.001), serum iron(p<0.001) and transferrin saturation(p<0.001) were significantly increased. The effect of cereal supplementation in children with iron deficient erythropoeisis was more effective to improve the iron nutritional status than children with iron depletion. It was concluded that cereal supplementation program in anemic children was also effective to improve iron nutritional status.
