OBJECTIVETo analyze the differences in anthropometric measurements between Mongolia and Han girls and understand the characteristics of their physical development in two ethnic groups.

METHODSThe data on anthropometric measurements of Mongolia and Han girls aged 9-17 years in Inner Mongolia were obtained from the Chinese National Survey on Student's Constitution and Health (CNSSCH) in 2010, and the data included body height, sitting height, chest circumference, weight, triceps skinfold thickness (TST), scapular skinfold thickness (SST), abdominal skinfold thickness (AST), and having menarche or not. The girls were divided into two groups according to having menarche or not, and the differences in anthropometric measurements between Mongolia and Han girls were analyzed for the two groups, respectively.

RESULTSThe proportions of Mongolia girls (9-17 years) who have experienced menarche was higher than that of Han girls (67.6%,1 049/1 553) vs (62.9%,1 837/2 922) (χ² = 9.17, P = 0.002). In girls without menarche (9-14 years), sitting height, AST, and BMI in Mongolia girls was 0.5 cm, 1.6 mm, and 0.4 kg/m², respectively, which were higher than those in Han girls (all P < 0.05). In girls who have experienced menarche (11-17 years), height and SST in Han girls was 0.8 cm, and 1.0 mm, respectively, which were higher than those in Mongolia girls (all P values < 0.01); TST, AST and BMI in Mongolia girls were 0.9 mm, 2.9 mm, and 0.3 kg/m², respectively, which were higher than those in Han girls (all P values < 0.05), respectively.

CONCLUSIONBody AST and BMI in Mongolia girls are higher than those in Han girls, while body height in Han girls is better than that in Mongolia girls after menarche. The differences of physical development between Mongolia girls and Han girls might be different before and after experiencing menarche.

OBJECTIVETo analyze the correlation between children and adolescents' body shape parameters and parent's dissatisfaction on it.

METHODSStratified cluster sampling method was used to select students and their parents, and height, weight, waist circumference (WC), hip circumference (HC), skinfold thichness of the students were measured. Body image from parents was studied through the 'Ma body figural shape'. Correlation between body shape parameters and dissatisfaction towards them from the parents was analyzed under both simple- and multiple-level methods.

RESULTSThe overall prevalence of dissatisfaction on body-shapes from parents was 69.0%, including 28.6% of the parents expecting children to be fat (PEBF) while, 40.4% of the parents expecting their children to be thin (PEBT). In males, parameters as height, weight, WC, HC, skin fold thickness, BMI in PEBT were 1.9 cm, 11.9 kg, 13.2 cm, 8.8 cm, 32.3 mm, 4.7 kg/m² respectively, all higher than the satisfaction from the parents (PBIS) (all P < 0.05), and these parameters were 2.3 cm, 7.1 kg, 7.2 cm, 5.8 cm, 14.1 mm, 2.3 kg/m² higher in PBIS than that of PEBF, respectively (all P < 0.05). In females, parameters as weight, WC, HC, skinfold thickness, BMI in PEBT appeared to be 8.6 kg, 9.1 cm, 6.6 cm, 21.9 mm, 3.5 kg/m² higher than that of PBIS (all P < 0.01), and were 5.5 kg, 5.9 cm, 5.4 cm, 10.4 mm, 1.8 kg/m² higher in PBIS than that of PEBF, respectively, plus the difference of height was 3.6 cm more (P < 0.01). Differences of body shape on parameters between PEBT and PBIS were larger in primary school students than in middle school students. However, the differences of body shape parameters between PBIS and PEBF appeared higher in middle school students than in primary school male students, but were higher in female students in primary than in middle school students.

CONCLUSIONThe prevalence of body dissatisfaction related to children and adolscents' body shape parameters from parents was high. Parents in the PEBT group seemed to have paid more attention to children's body shape parameters at low age. However, parents in PEBF group might have paid more attention to children's body shape parameters at high age in males or at low age in females.

PURPOSE: Obesity is a significant health problem with medical and psychological consequences for children and adolescents. The purpose of this study was to assess the correlation between body fat percent using bioelectrical impedance(BI) and other variable methods. METHODS: We measured height, weight, body mass index(BMI) and body fat percent by skinfold thickness(ST) and BI in 1,035(496 male; 539 female) children from seven to 18 years of age. The correlation coefficients between BI and each of the other different methods were obtained. The sensitivity and specificity to predict obesity by these several methods were studied. RESULTS: Fat percent estimated by BI analysis and BMI showed a strong correlation(r=0.749). Fat percent estimated by BI analysis and ST showed a very strong correlation(r=0.835). At the 95th percentile cut-off point for BI, ST showed a sensitivity of 57.7%, and a specificity of 97.6% for estimating body fat. At the 95th percentile cut-off point for BI, BMI showed a sensitivity of 84.9%, and a specificity of 99.3% for estimating body fat. CONCLUSION: The fat percent estimated by BI analysis correlated strongly with ST or BMI. BI analysis is an objective and accurate method for estimating body fat in childhood obesity.

The purpose of this study was to compare the anthropometry and nutrition knowledge, food behaviour and lifestyle of women college students with different obesity indexes. The subjects were 251 women college students who were randomly selected from Kunsan National University. The height, body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were measured, and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their Body Mass Index (BMI): underweight, normal weight and overweight. The results were as follows. Their body weight, soft/lean mass, fat mass, percentage of body fat, and fat distribution were significantly higher in the overweight subjects when compared to the underweight or normal weight subjects. Standard of living, self-recognition of health status and duration of exercise were significantly correlated with their BMIs. Self-satisfaction with body weight decreased as the BMI increased. Most subjects had poor habits such as skipping meals and lack of exercises. The overweight and the underweight groups skipped meals more frequently than the normal weight group. There were no significant differences in the scores on the nutritional knowledge and the dietary behaviour of the subjects with different BMIs. Therefore, proper nutritional education on regular meals and intervention are required if women college students are to have normal weights and healthy lifestyles.

The aim of this study was to represent the trend of early menarche and to assess the association of age at menarche with anthropometric profiles of Korean children and adolescents. A cross sectional survey was conducted with 13,371 girls aged 10 to 18 yr, recruited nationwide from April, 2005 to March, 2006. Height, weight and waist circumference of the subjects were measured; and the subjects self-reported their ages at menarche. We found that the menarcheal girls were taller (P<0.05 for the girls between 10 and 14 yr) and heavier (P<0.05 for the girls between 10 and 18 yr) than non-menarcheal ones. Menarcheal girls also showed higher body mass index (BMI), and greater waist circumference than non-menarcheal ones. Significant differences were represented according to the age at menarche in terms of BMI, waist circumference, % body fat mass, waist hip ratio and neck circumference as well as height and weight (P<0.05). In conclusion, girls who matured early were taller and heavier in early adolescence than those who matured later.

We have determined the infusion rates of rocuronium in the elderly and young adult patients during sevoflurane and nitrous oxide anesthesia. The correlation of some anthropometric predictors with infusion rate of rocuronium was also investigated for both elderly and young adult. Participating patients were assigned to one of two groups: 1) young adult patients aged 20 to 50 years (n = 30) ; 2) elderly patients aged over 65 years (n = 30). The anthropometric variables such as height, weight, ratio of weight to body surface area, subscapularis and suprailiac skin folds, body surface area, body mass index and % ideal body weight were evaluated as predictors for infusion rate. The infusion rate in elderly patients was significantly less compared with that in young adult patients (p < 0.05). In elderly patients, no anthropometric predictor was related to the infusion rate of rocuronium. This suggests that the infusion rate of rocuronium for an elderly patient needs to be individualized by monitoring neuromuscular transmission to avoid excessive dose.

OBJECTIVETo investigate the correlation between nonalcoholic fatty liver disease (NAFLD) and three anthropometric indices, namely waist to hip ratio (WHR), body mass index (BMI) and waist to height ratio (WHtR).

METHODSThis retrospective case-control study involved 77 NAFLD patients and 50 patients without such disease, and their data of the 3 anthropometric indices were collected. Risk correlation analysis and Mantel-Haenszel chi-square test were used for correlation analysis.

RESULTSNAFLD was significantly correlated to WHR (chi(2)(MH)=59.609, P<0.001; odds ratio=30.522, 95% CI 12.815-72.695), WHtR (chi(2)(MH)=45.316, P<0.001; odds ratio=21.037, 95% CI 8.665-51.072) and showed a dose-response relationship with BMI (chi(2)=25.017, P<0.001).

CONCLUSIONThese results support a close correlation between NAFLD and the 3 anthropometric indices, indicating that BMI, WHR and WHtR can be significant predictors of NAFLD and have potential value for evaluating and predicting NAFLD.

PURPOSE: To determine the frequency of past and present obesity among patients with NIDDM and to identify the differences of body fat, blood pressure and C-peptide/glucose ratio according to obese diabetic patients (BMI> or =25 kg/m2) and nonobese (BMI<25 kg/m2). Also the final factor is to observe the anthrometric change patterns in the study. METHOD: The weight at 20 years-old, previous maximal body weight, and acute weight loss were queried. Current height, body weight, BMI, waist & hip circumferences, waist-hip ratio, skinfold thicknesses, blood pressure, fasting blood glucose, and fasting C-peptide were measured in one hundred sixty-seven NIDDM patients. The differences of the parameters ccording to obese and nonobese, and three anthropometric change patterns were analyzed. RESULT: Results were as follows: 1. 66.5 % of the NIDDM patients had a history of past obesity as assessed by their maximum weight, while only 33.2% of them were currently obese (p's < 0.001). 2. The waist & hip circumferences, skinfold thicknesses, systolic, diastolic & mean arterial blood pressure in obese patients were greater than those of nonobese patients (all p's < 0.001). 3. The waist and the hip circumferences, and skinfold thicknesses (subscapula & triceps) were highest among the obese-obese group. WHR and abdominal skinfold thickness in the obese-obese and obese-nonobese groups were higher than those in the nonobese- nonobese group. Systolic & diastolic and mean arterial blood pressures in the obese-obese group were higher than those of obese-nonobese and nonobese-nonobese groups (all p's < 0.005).4. The abdominal and subscapular skinfold thicknesses in female diabetic patients were greater than those of male patients (all p's <0.0001). CONCLUSION: Although most Korean NIDDM patients were previously obese, many of them were not obese during the course of the study. Greater central and upper body adiposicity and higher blood pressure was shown in obese diabetic patients. Also, greater central and upper body adiposicity was demonstrated in female diabetic patients.

Childhood obesity prevalence has been increased and known to be related to various diseases and mortality in adult and body mass index (BMI) has been widely used as a screening tool in children with obesity. It is important to understand what BMI is and its limitations. BMI is a measure of weight adjusted for height. Weight scales to height with a power of about 2, is the basis of BMI (weight/height2) as the scaling of body weight to height across adults provides powers rounded to 2. BMI has the advantage of a simple and noninvasive surrogate measure of body fat, but it has limitation in differentiating body fat from lean (fat free) mass and low-moderate sensitivity is problematic for clinical applications. Among overweight children higher BMI levels can be a result of increased either fat or fat-free mass. BMI could be divided into fat-free mass index and fat mass index. Monitoring of the changes in body composition is important as distinguishing changes in each component occur with rapid growth in adolescents as it is occur in concert with changes in the hormonal environment. Reference values for each body composition indexes and chart created with selected percentiles of a normal adolescent population could be helpful in growth assessment and health risk evaluation.

BACKGROUND: Adiponectin is an adipocytokine that is highly specific to adipose tissue. In contrast to other adipocytokine, the adiponectin levels are decreased in obesity and/or type 2 diabetes. There are few studies regarding the correlation between the adiponectin concentration and obesity in children. Thus, whether the serum adiponectin concentrations are associated with adiposity in children was investigated. METHODS: One hundred and sixty four subjects were selected from the participants in an ongoing study on the relationship between birth weight and insulin resistance in children. The current weights, heights, body fat percentages, waist circumferences, blood pressures, lipid profiles and insulin resistance, by the HOMA method, were measured in all the subjects. The serum adiponectin concentrations were determined by a validated sandwich ELISA, using a human adiponectin-specific antibody. RESULTS: The serum adiponectin concentration was negatively correlated with the body mass index, waist circumference, systolic blood pressure, insulin resistance by HOMA and serum triglycerides, and positively correlated with the serum HDL cholesterol level. The serum adiponectin concentrations in the boys were significantly lower than in the girls. In a multiple regression analysis, the serum adiponectin concentration was strongly associated with waist circumference and gender. CONCLUSION: It is concluded that there was an inverse relationship between the serum adiponectin concentration and abdominal adiposity in children. However, further studies on independent gender differences on adiponectin are needed.
