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.

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 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.

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.

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.

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: Anogential distance (AGD) and the 2:4 digit length ratio appear to provide a reliable guide to fetal androgen exposure. We intended to investigate the current status of penile size and the relationship between penile length and AGD or digit length according to birth weight in Korean newborn infants. MATERIALS AND METHODS: Between May 2013 and February 2014, among a total of 78 newborn male infants, 55 infants were prospectively included in this study. Newborn male infants with a gestational age of 38 to 42 weeks and birth weight>2.5 kg were assigned to the NW group (n=24) and those with a gestational age<38 weeks and birth weight<2.5 kg were assigned to the LW group (n=31). Penile size and other variables were compared between the two groups. RESULTS: Stretched penile length of the NW group was 3.3+/-0.2 cm, which did not differ significantly from that reported in 1987. All parameters including height, weight, penile length, testicular size, AGD, and digit length were significantly lower in the LW group than in the NW group. However, there were no significant differences in AGD ratio or 2:4 digit length ratio between the two groups. CONCLUSIONS: The penile length of newborn infants has not changed over the last quarter century in Korea. With normal penile appearance, the AGD ratio and 2:4 digit length ratio are consistent irrespective of birth weight, whereas AGD, digit length, and penile length are significantly smaller in newborns with low birth weight.

This study was carried out to investigate among adolescents (total = 729) the relationship between their self-esteem, body-cathexis, their attitudes toward the importance of their bodies, their anthropometric characteristics, their perceptions of their body shapes and their experiences with weight control. The results are summarized as follows: The mean values for self-esteem and body-cathexis were generally low, but these values were significantly higher among boys than girls (p < 0.01 - 0.001). However the mean values for their attitudes toward the importance of their bodies were relatively high and were significantly higher among girls than boys (p < 0.01). The mean values for Percent Ideal Body Weight (PIBW) and Body Mass Index (BMI) were normal and no significant differences between the genders were observed. The distribution of the PIBW and the BMI values showed a higher rate for normal weights among the girlsand a higher rate for underweightedness and obesity among the boys (p < 0.01). With regard to their perception of their body image, among the boys, their current figures were almost identical with their idea of an ideal figure, but among the girls, their idea of an ideal figure was thinner than their current figure. The girls were more dissatisfied with their own body image than the boys (p < 0.001). Fifty-four percent of the subjects had previous weight control experience, and the girls had significantly more experience than the boys (p < 0.001). Their main reason for practising weight control was to lose weight (65.3%). Those who had more weight control experience had lower satisfaction with their body shapes, higher PIBW, higher BMIs or currently had fatter figures. Their standard image of their figures was influenced by TV (40.3%) and friends (36.9%). There was a weakly positive correlation between their self-esteem and their satisfaction with their body shapes, and a weakly negative correlation between their satisfaction with their body shapes and their attitudes toward the importance of their bodies. These results suggest the necessity for an educational program for adolescents as to foster a positive body image. Such a program should consider psychological factors such as selfesteem, satisfaction with body shape and attitudes toward the importance of the body

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.

Objective: To investigate the associations of obesity and physical activity with cognition in the elderly. Methods: A cross-sectional survey was conducted from October 2009 to June 2010 among people aged ≥50 years selected through multistage random cluster sampling in Shanghai. The subjects' body weight, body height, waist circumference and hip circumference were measured to calculate body mass index (BMI) and waist-hip ratio (WHR), and the data on self-reported physical activity level were collected through questionnaire survey. A comprehensive battery of cognitive tests was conducted to assess subjects' cognitive functions, including verbal recall, forward digit span (FDS), backward digit span (BDS), and verbal fluency (VF). General linear model was used to examine the associations of BMI, WHR and physical activity with cognition. Results: A total of 7 913 participants were included, with a median age of 60 years. Age, sex, education level, income level, BMI, WHR and physical activity level were significantly associated with cognitive scores in univariate analysis. After adjusted for age, sex, education level and income level, BMI was no longer significantly associated with cognitive scores in all cognitive functions (all P>0.01). WHR was significantly associated with VF score (P<0.01). Abdominally obese participants had lower VF score than non-abdominally obese participants (P<0.01). Physical activity level was significantly associated with all cognitive functions (P<0.01). Compared with participants with moderate physical activity level, participants with low physical activity level had lower scores in all cognitive functions (P<0.01). Conclusion: Abdominal obesity and low physical activity level were negatively associated with cognition level in the elderly, suggesting that waist circumference control and physical activity might help maintain cognition in the elderly.
