The study was conducted to investigate the factors associated with bone mineral content (BMC) changes among early pubertal aged girls. Two hundred and thirty girls between 9 to 11 years of age participated in (our surveys over 2 year period. During each survey, dietary intakes were collected with 3-day food records, BMC of left leg's calcaneus were measured by PIXI (Lunar Ltd.) and body composition was measured by bioimpedance method (Inbody 3.0 Biospace Co. Ltd, Seoul, Korea). Mean values of BMC increased in consecutive measurements -1.48 g, 1.54 g, 1.61 g and 1.66 g. The change of BMC between the first and last measurements was significantly positively correlated with % body fat, negatively correlated with BMC at the baseline (p < 0.05). Change of BMC was also significantly positively correlated with % change of lean mass and mineral mass between the first and last measurements. Nutrient intakes during the study period were calculated as mean daily intakes from all surveys. Mean daily intakes of Vit. C and Vit. $B_6$ were positively and isoflavone intake was negatively correlated with changes of BMC (p < 0.05). In stepwise regression of BMC change with body composition and nutrient intakes, baseline values of BMC, weight, BMI and age, % change of mineral mass during the study period, mean intakes of isoflavone, Vit. $B_6$, protein, carotene and zinc were significant explanatory variables ($R^2=0.38$, p <.001, F = 32.39). The results imply that the change of BMC among early pubertal aged girls are associated with some body composition and intakes of certain nutrients.

This study was conducted to find and compare the effects of dietary habits on and obesity indices and nutrition intakes among four hundreds and seven healthy adults males subjects. Subjects were classified as regular meal group(RMG) and irregular meal group(IRMG). Two hundreds and thirteen subjects of RMG had regularly 3times meal(time and amount) per 1 day during more than last 6 month. One hudred and ninety four subjects of IRMG(n=194) were not had regularly meal during last 6 month. Obesity indices were BMI(Body Mass Index), WHR(Waist Hip Ratio) and PIBW(Percentage of Ideal Body Weight). And the mean BMI, WHR and PIBW of RMG and IRMG were 23.1, 0.91, 104.8 and 24.7, 0.93, 112.9. PIBW of IMG were significantly lower than IRMG(p<0.01). The mean daily intakes of starches, seeds, meats, eggs, fishes, milk, fats and processed food intakes of RMG were significantly lower than IRMG. And the mean daily intakes of vegetables, mushrooms and beverages intakes of the IRMG were significantly lower than RMG. Energy intake of RMG and IRMG were 1978.2kcal and 1988.2kcal. For nutrient intake, vitamin C intake of IRMG was significantly lower than RMG. But niacin and cholesterol intake of RMG were significantly lower than the IRMG. Meal regularity was mainly related with obesity indices and nutrition intakes. Therefore, it might be necessary to manage meal regularity to prevent obesity and chronic disease in Korean adult males.

Objectives: The purpose of this study was to evaluate the main sources of dietary sodium and potassium intake in Koreans by gender, age and regions. Methods: We used the data from 2010-2012 KNHANES. A total of 20,387 subjects aged 8 years and older were included. Intakes were compared by gender, age (8-18, 19-49 and >50 years) and geographical regions in Korea. Dishes were classified into 28 dish groups based on cooking methods. Statistical analysis was performed by using the SAS 9.3 and SUDAAN 11.0.1 software. Results: The mean sodium intake of Koreans was $4866.5{\pm}35.9mg/day$, which was 2.4 times higher than the adequate intake (AI) of sodium for Koreans. We found that daily sodium intakes were significantly different by age, gender and regions. Men and aged over 50 years had significantly higher sodium intake than women and other age groups. The mean potassium intake in Koreans was $3002.2{\pm}19.4mg/day$ and daily potassium intakes were significantly different by age, gender and regions. Women and age 50 years and over had significantly higher potassium intakes than men and other age groups. The average Na/K ratio was $2.89{\pm}0.01$ and was highest in men and in the age group of 19-49 years. The major sources of dietary sodium were soup and stew, followed by Kimchi, noodles and dumpling, pickled vegetables and seasonings, which represented 63.1 % of total sodium intakes. Soup and stew or Kimchi were the primary sources of dietary sodium intake. The major sources of dietary potassium were cooked rice, followed by soup and stew, Kimchi, fruits and beverages. Conclusions: Sodium and potassium intakes and the major sources of those were significantly different by gender, age groups and regions. Therefore, different approaches based on gender, age and regions are needed to decrease sodium intake and increase potassium intake.

The purpose of this study was to examine the correlation between nutrient intakes and bone mineral density in female university students. A total 27 female university students were measured the anthropometric characteristics, dietary intake and the bone mineral density of carpus using DEXA. The average age, height, weight, % body fat, WHR, and BMI of the subjects were 22.7 years, 161.5 cm, 57.0 kg, 29.9%, 0.8, 21.8 kg/$m^2$, respectively. Bone mineral density of ultradis and distal carpus as T-value were -1.5 and -0.4, respectively. The daily energy intake of the subjects was 1589.0kcal. And the intakes of energy, calcium, iron, zinc, vitamin $B_2$, and folic acid did not meet the Korean RDAs. The daily total food intake of the subjects was 1011.0g and food intake from cereals and vegetables was high. The major food groups of mineral intake were vegetables/cereals/milks/fishes for calcium, cereals/meat/vegetables/fishes for phosphorus, cereals/vegetables/meats for iron, seasonings/vegetables/cereals for sodium, vegetables/cereals/seasonings for potassium, and cereals/meats for zinc. The body weight and body mass index were significantly positive correlated to the bone mineral density of average carpus, respectively. The intakes of animal calcium and vitamin $B_2$ were significantly negative correlated to the bone mineral density of average carpus, respectively. In conclusion, bone mineral density in carpus and nutrient intakes of some female university students were low. Therefore, health management and the study on relation between bone mineral density in various site and long-term intakes of nutrients in many subjects are required.

To determine the relationships between soybean food intake, dietary isoflavone intake, and osteoporosis incidence, questionnaire surveys, bone mineral density measurements, and dietary surveys by food record were performed with 19 postmenopausal women ($57.6{\pm}7.3$ yrs of age) in Daejeon city. The subjects were divided into two groups: an 'osteoporosis group' (OG, n=10) and a 'normal group' (NG, n=9). Mean age, height, and body weight were similar between the two groups but BMI was higher in OG than in NG. Mean age at menarche was not different between the two groups. However, mean number of childbirths was greater in OG than in NG and mean total period of lactation was shorter in OG. Mean exercise time per week was similar between the two groups, and mean time of sunlight exposure tended to be shorter in OG. Mean daily intake of calcium was lower in OG whereas sodium intake was higher in OG. Mean daily intakes of total soybean food (OG: $203.8{\pm}84.6\;g/d$, NG: $285.0{\pm}146.3\;g/d$) and total dietary isoflavone (OG: $29.1{\pm}14.3\;mg/d$, NG: $38.3{\pm}23.1\;mg/d$) were not different between the two groups. However, greater intakes of soybean food and dietary isoflavone were associated with higher bone mineral density, respectively. The above results indicate that osteoporosis incidence tends to be influenced by BMI, maternal factors, dietary nutrient intakes, soybean food intakes, and dietary isoflavone intakes in postmenopausal women; although no significant differences in soybean food and dietary isoflavone intake were found between the two groups. This tendency implies that greater intakes of soybean food and dietary isoflavone lead to lower incidence of osteoporosis in postmenopausal women.

This study was done to investigate the 12 college volleyball player's food behavior, nutrient intakes, and their serum lipid levels during the periods of training and detraining and to provide basic data for an effective program for the volleyball players during the period of detraining after the game season. The results were summarized as follows : The total daily energy intake of the players was $3,363{\pm}339kcal and 3,692{\pm}499kcal$ during the periods of the training and detraining, respectively. During the training period, daily intakes of protein, calcium and vitamin A, and $B_2$ were lower than the recommended dietary allowance for the players. During the detraining period, the players' daily intakes of calcium, iron, and vitamin A were even lower. However, the consumption of alcohol was dramatically increased during the period of detraining. The levels of serum triglyceride and very low density lipoprotein were significantly increased during the detraining period. Basal metabolic rates were significantly increased after the training period and diastolic pressure was decreased during the detraining period. In conclusion, out results suggest that the detraining of volleyball players for 10 days after intensive training, negatively affects their food behavior and serum lipid concentrations. Therefore, for the improvement of performance for the next game season, a planned program for the players' detraining period should be developed.

A nutritional survey was made in 45 healthy Buddhist nuns (age : 20-34 yr) who have been vegetarians for more than 5 years and 20 female college students (aga : 20-22 yr) as a control group in Kyungpook province. Daily calorie intake of the Buddhist nuns and students were 1947 and 1815 kcal, respectively. The ratio of percent calorie of carbohydrate : fat : protein from total calories in the Buddhist nuns was 84 : 11 : 5 and that of the students was 70 : 15 : 15, respecting. The Buddhist nuns had significatly higher carbohydrate intake but markedly lower lipid intake than the students. Daily intakes of thiamin, niacin and ascorbic acid in the Buddhist nuns were higher, but those of iron, calcium and vitamin A were lower than the recommended daily allowances. Compared with the students, the Buddhist nuns had greater intakes of ascorbic acid, vitamin A, thiamin, niacin, and calcium. Anthropometric measurement showed that the Buddhist nuns had significantly higher values than the students in body weight, skinfold thickness, body surface area, and obesity index. There were highly significant correlations between anthropometric measurements and obesity index(0.55< r <0.99). On the other hands, correlation coefficients between nutrients intakes and skinfold thickness and obesity were very low(0.01< r <0.37). The Buddhist nuns and students showed similar normal values of hemoglobin concentration, hematocrit, and blood pressure.

This study aims to examine the relationship between chewing ability and nutritional intake status in the rural elderly. The subjects were 150 rural-dwelling elderly persons(68 males and 82 females) aged 65 years and over in Sungju-Gun, Kyunfsangpookdo. The respondents were interviewed using the questionnaires and measurments taken from a 24-hour recall method from February to April in 1998. Fifty-nine subjects(39.3%) were classified with normal chewing ability and sixty-four subjects(42.7%) could carry out all of the 10 ADL items by themselves. In addition, the group who were able to chew had more teeth and significantly higher ADL scores than the other group(p<0.01), whereas DMF value was significantly lower(p<0.001). The subjects with normal chewing ability also had higher of intakes of energy, protein, fat, carbohydrates, dietary fiber, salt, potassium, niacin, thiamin and riboflavin than in the unable group(p<0.05). As far as daily food intakes were concerned, considerable differences were revealed in the levels of grain and products and vegetables consumed depending on chewing ability(p<0.001). The results of the stepwise and vegetables consumed depending on chewing ability daily living activities and health self-assessment(p<0.05) were the most significant factors for energy intake status.

A 4-week energy balance study was conducted to estimate the energy expenditure (EE) of 16 college age men and women, 20 to 26 year of age, by measurement of energy intakes and changes in body energy(BE) content(intake/balance technique), keeping their normal living pattern and maintenance body weight. Energy intake was measured by bomb calorimetry and estimated by food table. Fecal energy loss was calculated from nitrogen excreted. Fat mass was determined from body density estimated from skinfold tickness. 1) Gross energy (GE) intakes calculated from food table was not only 13.4% lower than those of bomb calorimetry but also lower 4 and 5% than metabolizable energy(ME) intakes for the male and female subjects, respectively. 2) Fecal energy loss was 7.2% and 6.9% proportion of the gross energy intake for the male and female subjects, respectively. 3) Mean daily metabolizable energy intakes estimated by subtract fecal and urinary energy loss was 2467kcal for the male subjects and 1897kcal for the female subjects. 4) Total body energy change estimated from body composition change over 31 days was decreased 7672kcal for the male subjects and 2689kcal for the female subjects. 5) Mean daily energy expenditure was 2714kcal (45kcal/kg of body weight) for the male subjects and 1984kcal(40kcal/kg of body weight) for the female subjects. 6) The estimated energy expenditure of college-age subjects in this study provide evidence to support the Recommended Dietary Allowances for energy of Korean normal adult.
