Objectives: Bone health in early adulthood, as individuals approach peak bone mass, plays a critical role in preventing osteoporosis later in life. This study aimed to investigate the associations between lifestyle and dietary factors, anthropometric measurements, and urinary bone resorption markers in young adults. Methods: A cross-sectional study was conducted with 100 healthy Korean adults (50 men and 50 women) in their 20s and early 30s. Bone mineral density (BMD), anthropometric measurements, dietary intake (24-hour recall), and urinary bone resorption indicators (deoxypyridinoline and N-terminal telopeptide of type I collagen) were analyzed. Variables were compared between the osteopenia and osteoporosis groups (OSTEO group: 30% men and 60% women) and the healthy control group. Results: Men in the OSTEO group were significantly taller than those in the control group (P < 0.05). Women in the OSTEO group had significantly lower body weight and body composition (muscle and body fat) than those in the normal group (P < 0.01). Men in the OSTEO group had a significantly higher intake of animal calcium (Ca) than those in the normal group (P < 0.05). Women in the OSTEO group had significantly higher dietary fiber, vitamin A, Ca, plant Ca, and potassium intake than did those in the normal group (P < 0.05). There were no significant differences in caffeinated beverage consumption, eating habits, or urinary bone resorption indicators between the OSTEO and control groups of either sex. Conclusions: In our study of young South Korean adults, we observed low bone density levels, with particularly low BMD in taller men and underweight women. We found a higher nutrient intake in the OSTEO group, indicating the possibility of reverse causality, a phenomenon often found in cross-sectional studies. Therefore, there is a need to further elucidate dietary factors related to osteoporosis in young adults through prospective cohort studies involving a larger population.

Concept of the comfort and fitness has become a major concern in the basic function of the ready.made clothes. Until now ready-made clothes were not made by on the basis of the bodytype, but by the body size only This research was performed to classify and characterize the bodytypes of Korean adult males. Sample size was 1290 subjects and their age range was from 19 to 54 years old. 25 variables from the photographic data were applied to analyze the bodytype of trunk. Data were analyzed by the multivariate method, especially factor and cluster analysis. The groups forming a cluster can be subdivided into 5 sets by crosstabulation extracted by the hierarchical cluster analysis. 5 bodytypes classified by the photographic sources could be combined with the anthropometric data and were demonstrated with 5 silhouette. Type 3 and 4 in trunk were dominant and were composed of the majority of 55.6% of the subjects. Bodytypes of Korean males were influenced by the degree of posture erectness and of curvature of the front side of the body in waist and abdomen.

This study was designed to investigate the effects of work postures and anthropometry on the musculoskeletal discomfort of the telephone operators involved in VDT tasks. The level of musculoskeletal discomfort were evaluated for 279 VDT operators from three different workplaces. The work postures and the anthropometric data were evaluated for 70 VDT operators out of the total of 279 operators. Multiple regression analysis was utilized to examine the relation- ship between the measured ergonomic variables and the level of the musculoskeletal discomfort. It is evident from the result of the study that the ergonomic factors have great influences on the level of the musculoskeletal discomfort.

The purpose of this study was to establish the range of the body frame size determination for elderly subjects. Anthropometric data were collected from over 60 years old 229 elderly peoples. Three methods for determining frame size were to measure elbow breadth, ankle breadth, and height to wrist circumference ratio. Among the three variables, ankle breadth exhibited the lowest correlation with skinfold thickness and changed little with age. A pairwise comparision among three methods for determining frame size showed that the highest incidence of overall agreement was achieved when the ankle breadth and elbow breadth were compared. This analysis supported that ankle breadth can be used as an indicator of frame size. Small, medium and large categories of ankle breadth were presented depending on whether the measurements were below the 15th, between the 15th and 85th, and above the 85th percentile for ankle breadth.

This study was conducted to analyze the effect of isoflavone intake on prevention of chronic disease in middle and old aged man. In this study we used FFQ (Food frequency questionnaire) and the isoflavone intake level of the subjects was 25.10 mg per day. We divided the subjects into three group -high, medium, low isoflavone intake level- and investigated the relation among isoflavone intake level and clinical/anthropometric characteristics. The intake of isoflavone was inversely related with the body fat in male subjects. And we also divided the subjects into 2 groups with normal and abnormal clinical/anthropometric risk factor. The isoflavone intake level of the abnormal group with high TG, high WHR and high body fat was lower than the normal group. The main food source of isoflavone was soybean curd, bean sprout, soybean paste, soybean and soy milk, and we also investigated the relation between frequency of soybean food and anthropometric and clinical variables. The frequencies of soybean curd, soybean paste, soybean broth, soy milk, bean sprouts, peanuts, soybean and dambuk as well as intake of isoflavone were inversely correlated with some anthropometric and clinical variables such as blood pressure, TG, BMI, % body fat, and waist-hip ratio, whereas positively correlated with HDL cholesterol, muscle mass and bone density. We suggest that high consumption of soy products and isoflavone is associated with decreased blood lipid and body fat in middle and old aged man and might be useful for prevention cardiovascular diseases. From this study, we obtained valuable basic information on recommended isoflavone intake level and guidelines for the prevention of some chronic diseases/health problems.

The aim of this study was to investigate the relationships among energy intakes, macronutrient intakes, macronutrient compositions, anthropometric and biochemical variables in natural environment of free-living female college students. The daily energy and macronutricnt intakes were analyzed by means of 3- week dictary records. The waist circumference and insulin level were best anthropometric and bio-chemical correlates with the energy, carbohydrate and protein intakes respectively. However, there were no relationships between waist circumference and insulin verse macronutrient compositions that macro-nutrient intakes were expressed as by the percentage of daily encrgy intakes. There were no relationships between BWI, weight, perccnt body fat and fat mass vs. energy and macronutrient intakes. However, BMI was positively related to the percentage of energy from fat and inversely related to the percentage of energy from carbohydrate in their habitual diet. Triglyceride was negatively correlated to the per-centage of energy from fat and fat intakes. Significant positive correlation was also observed bctween the percentage of energy from protein and HSL-cholcsterol.

Purpose: The purpose of this study is to develop three-dimensional computerized anthropometry(3DCA) and to compare its reliability and accuracy 3DCA with manual anthropometry(MA) for measurement of lips and nasal deformities in unilateral cleft lips and palate(UCLP) patients. Methods: Samples were consisted of six UCLP patients whose facial plaster models were available immediately before and 3 months after the cleft lip surgery. MA of the facial plaster models was carried out using an electronic caliper. In 3DCA, three-dimensional auto-measuring program was used to digitize landmarks and to measure three-dimensional virtual facial models (3DVFM), which was generated with a laser scanner and 3D virtual modeling program. Intraclass correlation coefficients(ICC) were calculated to evaluate reliability and reproducibility of the variables in both methods, and Wilcoxon's signed rank test was done to investigate the difference in values of the same variables of facial models of each patient between two methods. Results: All ICC values were higher than 0.8, so both methods could be considered reliable. Although most variables showed statistical differences between two methods(p<0.05), differences between mean values were very small and could be considered not significant in clinical situation. Conclusion: In clinical situation, 3DCA can be an objective, reliable and accurate tool for evaluation of lips and nasal deformities in the cleft patients.

Background Measuring grip and pinch strength is an important part of hand injury evaluation. Currently, there are no standardized values of normal grip and pinch strength among the Korean population, and lack of such data prevents objective evaluation of post-surgical recovery in strength. This study was designed to establish the normal values of grip and pinch strength among the healthy Korean population and to identify any dependent variables affecting grip and pinch strength. Methods A cross-sectional study was carried out. The inclusion criterion was being a healthy Korean person without a previous history of hand trauma. The grip strength was measured using a Jamar dynamometer. Pulp and key pinch strength were measured with a hydraulic pinch gauge. Intra-individual and inter-individual variations in these variables were analyzed in a standardized statistical manner. Results There were a total of 336 healthy participants between 13 and 77 years of age. As would be expected in any given population, the mean grip and pinch strength was greater in the right hand than the left. Male participants (137) showed mean strengths greater than female participants (199) when adjusted for age. Among the male participants, anthropometric variables correlated positively with grip strength, but no such correlations were identifiable in female participants in a statistically significant way. Conclusions Objective measurements of hand strength are an important component of hand injury evaluation, and population-specific normative data are essential for clinical and research purposes. This study reports updated normative hand strengths of the South Korean population in the 21st century.

Objective: A recently developed facial scanning method uses three-dimensional (3D) surface imaging with a light-emitting diode. Such scanning enables surface data to be captured in high-resolution color and at relatively fast speeds. The purpose of this study was to evaluate the accuracy and precision of 3D images obtained using the Morpheus 3D$^{(R)}$ scanner (Morpheus Co., Seoul, Korea). Methods: The sample comprised 30 subjects aged 24.34 years (mean $29.0{\pm}2.5$ years). To test the correlation between direct and 3D image measurements, 21 landmarks were labeled on the face of each subject. Sixteen direct measurements were obtained twice using digital calipers; the same measurements were then made on two sets of 3D facial images. The mean values of measurements obtained from both methods were compared. To investigate the precision, a comparison was made between two sets of measurements taken with each method. Results: When comparing the variables from both methods, five of the 16 possible anthropometric variables were found to be significantly different. However, in 12 of the 16 cases, the mean difference was under 1 mm. The average value of the differences for all variables was 0.75 mm. Precision was high in both methods, with error magnitudes under 0.5 mm. Conclusions: 3D scanning images have high levels of precision and fairly good congruence with traditional anthropometry methods, with mean differences of less than 1 mm. 3D surface imaging using the Morpheus 3D$^{(R)}$ scanner is therefore a clinically acceptable method of recording facial integumental data.

The purpose of this study was to identify the change in the girth of anthropometric variables during menstrual cycle, and to provide basal data for health promotion program development during pre-menstrual phase and menstrual phase. Participants were 10 healthy women university students without menstrual irregularity, subjective premenstrual syndrome, premenstrual dysphoric disorder, dymenorrhea, obstetrician and gynecologic disease. Chest girth(axillary and papillary), waist girth(half point between iliac crest and 12th rib, and navel), and hip girth were repeatedly measured in menstrual phase, follicular phase, luteal phase during single menstrual cycle. As a result, axillary chest girth in menstrual phase was significantly increased than that in luteal phase. Papillary chest girth and waist girth at half point between iliac crest and 12th rib in menstrual phase were significantly increased than those in follicular phase. No significance was shown in chest and waist girth between follicular and luteal phase. No significance was shown in hip girth during menstrual cycle. In conclusion, signicant difference was shown in chest and waist girth during menstrual cycle. And it is suggested that succeeding research should be carried out with reference to body weight, body fat, blood and local hormone concentration during menstrual cycle.
