This study was undertaken to investigate iron status and related factors in female college students residing in Gyeongnam. The subjects were divided into normal (40.8%) and iron deficiency (ID) groups (59.2%) by iron status. Mean height, weight, lean body mass, percent body fat, body mass index, and wrist to hip ratio were not significantly different between the groups, but basic metabolic rate was significantly higher in the normal group than that in the ID group. The levels of hemoglobin, hematocrit, serum ferritin, transferrin saturation, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were significantly higher in the normal group than those in the ID group. However, total iron binding capacity was significantly lower in the normal group than that in the ID group. Daily intake of protein, heme-Fe, niacin, and vitamin C were significantly higher in the normal group than those in the ID group. The mean intake of protein, Fe, niacin, vitamin $B_{12}$, and vitamin C based on the Korean recommended intake (RI) were significantly higher in the normal group than those in the ID group. The mean intakes of Ca, vitamin $B_{12}$, and folate in both groups were < 75% of the Korean RI. In conclusion, increasing dietary heme-Fe and vitamin C may be helpful for preventing ID anemia in female college students.
This study was carried out to evaluate the iron nutrition status of 212 middle school students(106 males and 106 females) residing in Seoul(13-14 years old ) using eating patterns and a measurement of anthropometrical determination and hematological indices. Fasting blood samples were taken from all subjects, serum iron (SI) and total iron binding capacity(TIBC) concentrations were measured, and transferrin saturation(TS) levels were calculated. Iron and other nutrient intakes were estimated by a semi-quantitative frequency questionnaire. The level of TS(%) which was calculated with TIBC and SI in females(20.4$\mu\textrm{g}$/dl) was significantly lower(p<0.050 than that of males (27.4$\mu\textrm{g}$/㎗). The prevalence of iron deficiency was found to be 36.7% when defined by TS(%) (<05%). Mean daily intake of total iron in the study subjects was 14mg and heme iron intake was 5.4mg(38.1%) . There was a significant negative correlation between the level of SI and the income level and a positive correlation with the level of TIBC and the income level. TIBC had a positive correlation with the anthropometric variables(Ht, Wt, BMI, RI and PIBW). SI and TS had a negative correlation with body fat percentage. There was a positive correlation between energy intake and TIBC only among females. The logistic regression analysis revealed that income level, body fat percentage , weight and energy intake were major determinants of low SI levels. Among the determinants of abnormal TIBC levels were weight , height, income level and energy intake. Finally , among those of low TS% were iron and energy intake and income level. These observations suggest that physical status, body fat percentage energy and iron intakes and income level are risk factors for iron-deficiency anemia among the middle school students in Seoul.
Measurement and analysis of the physical status (height, body weight, breast girth, sitting height. length of leg, length of thigh, thigh girth, crural length, length of arm, brachial length, antebrachial girth and skinfold thickness), physical types and the growth were made to the 360 Korean middle and high school boys aged between 12 and 17 years in Taegu City. The physical status was evaluated and expressed as dispersion and the Physical type as percentage of each status to height, and the growth was analysed by the growth formula. The results are as follows; 1) The increase of the volumes of Physical status was slowest between 12 and 13 years and fastest between 13 and 14 years in general. 2) The increase of the volumes of thigh girth and antebrachial girth showed a linear pattern until 16 years. 3) The coefficient of variation was largest in skinfold thickness $(16.3{\sim}28.4%)$ followed by body weight $(10.0{\sim}14.3%)$, antebrachial girth $(4.8{\sim}19.60%)$ and length of thigh$(6.3{\sim}13.6%)$. The coefficients of variation in all the other status were similar $(4{\sim}7%)$. 4)The physical indices of body weight, breast girth, sitting height, length of thigh, thigh girth, antebrachial girth and skinfold thickness increased as age increased while the others decreased except the brachial length, which showed no significant change. 5) Ratio of growth quantity was largest in body weight followed by skinfold thickness, and the others were all similar. 6) Growth rate and specific growth rate decreased in the all the status analysed as age increased except in the skinfold thickness in which an increase was noted. 7) Growth gradient was increased along the increase of age in breast girth, sitting height, crural length, brachial length and in skinfold thickness. However a decrease was observed in the other status except in the body weight which was decreased until 15 years of age and increased thereafter.
This study is to investigate consequent nutrient intake status, influence of body mass index(BMI), and fat distribution on the silk amino peptide(SAP) and dietary fiber supplementation. During 2 months of this research (January to March, 2002), 45 women aged 20yr – 30yr (average age 24.6yr) were selected as subjects. Nutrient intake was investigated by questionnaire, 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method(Segmental bioimpedance assay, In body 3.0). The results are as follows: mean body weight 57.7kg, mean body height 161.9cm mean BMI 22.0, and mean food habit score was 8.47. Defecation frequency was increased by dietary fiber supplementation. Frequency of pain during defecation was significantly decreased by dietary fiber supplementation (p<0.01). Feeling of residual feces was significantly improved by dietary fiber supplementation(p<0.001). Status of energy and carbohydrate intakes significantly decreased after dietary fiber supplementation(P<0.05). Body fat and WHR(waist hip ratio) significantly decreased after dietary fiber supplementation(P<0.001), and percent body fat was decreased by dietary fiber supplementation, significantly(P<0.05). Above results of this study show that dietary fiber-added routine diet improves defecation condition, and lessens body fat, percent body fat without losing body muscle. Especially, declination of abdominal fat and WHR were notable. That meant decreased risk factor.
In order to establish a new biochemical parameter to evaluate nuitrtitional status. the present paper presents a paper chromatographic procedure. which enables clear separation of the essential and nonessential free amino acids in the urine without desalting the sample prior to chromatographic analysis The children of school age. showing difference in their body physiques. from the rural and urban areas in Korea were selected in collecting the 24 hour urine specimens. with the following conclusions. (1) A new procedure utilyzing paper chromatographic analysis. without desalting the urine. was proposed to establish a new biochemical parameter for nutritional status by analyzing the ratio of the nonessential to the essential free amino acids in urine. (2) According to the pesent procedure. the ratio obtained with the urban children was proved to be $1.33{\pm}0.18$, whereas that with the rural children was $1.59{\pm}0.24$; suggesting the lower the ratio. the superior the body physiques and nutritional status. (3) The ratio had a statistically significant correlation with the body and sitting heights as well as the body weight. but not with the girth.

Purpose: Weight loss and deterioration in body composition are observed in patients with gastric cancer (GC) following gastrectomy. This study aimed to investigate the impact of residual stomach volume (RSV) on the nutritional status and body composition of patients with GC treated with distal gastrectomy. Materials and Methods: In total, 227 patients who underwent minimally invasive distal gastrectomy with Billroth 1 anastomosis for stage I GC between February 2015 and May 2018 were enrolled. Clinicodemographic and laboratory data were collected from the GC registry. The RSV, abdominal muscle area, and subcutaneous/visceral fat areas were measured using computed tomography data. Results: A larger RSV was associated with a lower decrease in the nutritional risk index (P=0.004) and hemoglobin level (P=0.003) during the first 3 months after surgery, and better recovery at 12 months. A larger RSV demonstrated an advantage in the preservation of abdominal muscle area (P=0.02) and visceral fat (P=0.04) after surgery, as well as less reduction in weight (P=0.02) and body mass index (P=0.03). Conclusions: Larger RSV was associated with improved nutritional status and better preservation of muscle and fat after distal gastrectomy.
BACKGROUND/OBJECTIVES: Maintaining total muscle mass in the older adults with swallowing difficulty (dysphagia) is important for preserving swallowing function. Increasing protein intake can help sustain lean body mass in the older adults. The aim of this study was to evaluate the effect of various high-protein texture-modified foods (HPTMFs) on muscle mass and perform dietary assessment in ≥ 65-yrs-old patients with dysphagia. SUBJECTS/METHODS: Participants (n = 10) received the newly developed HPTMFs (average 595.23 ± 66.75 kcal/day of energy, 54.22 ± 6.32 g/day of protein) for 10 days. Relative handgrip strength (RHS), mid-upper arm circumference (MUAC), body composition, mini nutritional assessment (MNA), mini dietary assessment (MDA), and Euro Quality-of-Life questionnaire 5-dimensional classification (EQ-5D) were assessed. RESULTS: After 10 days, an increase in MUAC (26.36 ± 2.35 cm to 28.50 ± 3.17 cm, P = 0.013) and RHS (0.38 ± 0.24 kg/kg body weight to 0.42 ± 0.22 kg/kg body weight, P = 0.046) was observed. Although MNA, MDA, EQ-5D, subjective health status, muscle mass, and calf circumference showed a tendency to increase after intervention, no significant differences were found. CONCLUSIONS: These results suggest that the HPTMFs can be used for improving the nutritional and health status in patients with dysphagia.
Menarche is a main indicator of sexual maturity which relates to a reproductive function. The onset of the menstrual cycle differs individually and is influenced by many variables such as socio-economic situation, race, genetics, climate, altitude, nutritional status, and physical growth. Among them physical growth has been known to be the most influencing factor, particularly when expressed as body fat designated by weight. This study intended to investigate the body composition of girls around the menarche period and to evaluate the minimal levels of weight and fat percentage needed for the onset of menarche. A total of 101 female subjects, aged 11 to 13 years, were recruited from the 5th and 6th grades of an elementary school, in Mokpo, Korea. The subjects were placed into one of two groups Pre-menarche and Post-menarche groups according to their experience with menarche. Thereafter, the subjects in the Post-group were placed into 4 subgroups based on the number of menstruations they experienced: Post-I (1-3 times), Post-II (4-6 times), Post-III (7-9 times), and Post-IV (> 10 times). The average age at the onset of menarche of the subjects in Post groups was $11.2 \pm 0.6$ years. There were significant differences in the data of anthropometry and body composition between the Pre and Post groups, although the mean ages of both Pre and Post groups were the same. Weight, waist, hip and thigh girths, fat percentage, and lean body mass of the Post groups were significantly higher than those of the Pre group. Height was not significantly different between the groups. Weight was highly correlated with body fat mass (r = 0.92. p < 0.001), fat percentage (r = 0.85, p < 0.001), and body mass index (r = 0.91, p < 0.001) These results indicate that weight, compared with height, reflects body composition well and influences the onset of the menstrual cycle. It could also be suggested that the minimal weight and fat percentage needed for the onset of menarche in Korean females are 41 kg and $17\%\;to\;19\%$, respectively.
The objective of this study was to investigate the relation of serum calcium level, body mass index(BMI) with bone status expressed as broadband ultrasound attenuation(BUA) measured by quantitative ultrasound (QUS) and the occurrence of osteopenia among adult men and women. Two hundred eleven(63 male and 148 female) workers who worked in 4 different battery factories were recruited from March 2005 to October 2005. BUA was used as a surrogate of bone mineral density and measured at left calcaneous bone area. The BUA value transformed into T-score by WHO standard conversion criteria to determine osteopenia (-2.5
The purpose of this study was to assess the needs for nutrition programs in the public health centers by general characteristics and body mass index (BMI) of community residents. Information of general characteristics of study participants including age, education, income, marital status, residence, and job, and resident's interest in nutrition programs, the preferred educational methods and the willingness to participate in nutrition programs were collected by an interview. Weight and height were measured and were used to calculate the BMI. The program that resident's were most interested in was 'diet therapy for chronic disease and counseling' ($28.5\%$), followed by 'nutritional management for the elderly' ($21.1\%$), and 'obesity and weight control' ($17.1\%$). 'Education and counseling by nutrition professionals' was the most preferred educational method. Among the programs that the subjects would participate in, if they were offered in public health centers, $65.8\%$ subjects would participate in 'diet therapy for chronic disease and counseling' programs, $64.9\%$ would participate in 'nutritional management for the elderly' programs and $52.2\%$ would participate in 'obesity and weight control' programs. The contents of programs that the subjects were interested in, the preferred methods and their willingness to participate nutrition programs differed significantly by age, income, education, marital status, and body mass index. The results imply that the planning of nutrition interventions in the public health centers must be tailored and targeted group specific by taking the participants general characteristics and body mass index into consideration. This would surely increase the nutrition program's effectiveness
