Body characteristics of the Zhuang-Dong ethnic groups in China / 解剖学报

Objective To investigate the body characteristics of zhuang-dong ethnic group. Methods Totally 14 Zhuang-Dong languages in Guizhou, Guangxi, Yunnan, Hainan and Hunan were measured with anthropometry. Results The foot breadth, upper arm length and forearm length of male of Zhuang-Dong ethnic group were not correlated with age, while crista iliaca breadth was positively correlated with age (P<0. 01), 24 indexes including weight, stature and tragion height are negatively correlated with age (P<0. 05 or P<0. 01) . Six indicators of Zhuang-Dong female' s foot breadth, hand length, height of suprasternal notch above sitting plane, upper extremity length, lower extremity length and upper arm length were not related with age, while four indicators of hand breadth at metacarpale, crista iliaca breadth, total arm length and forearm length were positively correlated with age (P< 0. 05 or P< 0. 01), while 18 indicators of weight, stature and tragion height were negatively correlated with age (P<0. 05 or P <0. 01). The vast majority of body index values had statistical significance among age groups. The average value of all body indexes of Zhuang-Dong ethnic groups was larger than that in female (P<0. 05 or P<0. 01), that was, the height, length and width of male body were larger than that of female. Principal component analysis showed that, the stature, sitting height, height of suprasternal notch above sitting plane and weight of Lingao people, Li nationality men and women were larger than those of other 12 Zhuang-Dong language group. Mulao and Bajia had similar human body characteristics. In addition, the mean values of human body indexes of the 14 Zhuang-Dong language group, Bulang ethnic group and Gejia ethnic group were lower than those of the northern Han nationality, the Mongolian Balhu ethnic group, the Mongolian Erdos ethnic group, the Heshuo ethnic group in Qinghai, the Uzbek ethnic group, the southern Han nationality, the Mosuo ethnic group, the Qiang ethnic group and the Yi ethnic group. Conclusion Men and women in Zhuang-Dong ethnic group have little weight, while men' s height belongs to short stature and female's height belongs to sub-medium stature. Zhuang-Dong ethnic group has the physical characteristics of ethnic minorities in southern China, and belongs to the physical type of short stature and light weight.

Impact of body characteristics on ultrasound-measured inferior vena cava parameters in Chinese children

Ultrasound-measured inferior vena cava (IVC) and abdominal aorta (Ao)-associated parameters have been used to predict volume status for decades, yet research focusing on the impact of individual physical characteristics, including gender, height/weight, body surface area (BSA), and age, assessed simultaneously on those parameters in Chinese children is lacking. The aim of the present study was to explore the impact of individual characteristics on maximum IVC diameter (IVCmax), Ao, and IVCmax/Ao in healthy Chinese children. From September to December 2015, 200 healthy children from 1 to 13 years of age were enrolled. IVCmax and Ao diameters were measured by 2D ultrasound. We found that age (years), height (cm), weight (kg), waist circumference (cm), and BSA (m2) were positively correlated with IVCmax and Ao. Multivariate linear regression showed that age was the only independent variable for IVCmax (mm) in female children, height was the only independent variable for IVCmax in male children, and age was the only independent variable for Ao in both females and males. IVCmax/Ao was not significantly influenced by the subjects' characteristics. In conclusion, IVCmax and Ao were more susceptible to subjects' characteristics than IVCmax/Ao. IVCmax/Ao could be a reliable and practical parameter in Chinese children as it was independent of age, height, and weight.

Body Characteristics of University Soccer Players Measured by Orthopedic Medical Check. A Look at the Hip Joint and Pelvis / 体力科学

The purpose of this study was to analyze the body characteristics of university soccer players, especially the hip joint and pelvis where chronic injuries frequently occur among soccer players.<BR>Body characteristics of seventy male university soccer players were surveyed by an orthopedic medical check. The Micro FET value (MF) was used as the unique test for the potential stress on the pubic symphysis. MF was defined as the pressure value at which a subject claimed tenderness from compression on the pubic symphysis.<BR>Among the various tests of the orthopedic medical check, trunk extension in the prone position and external rotation of the hip joint in the standing position correlated with MF. The same tendencies were observed in soccer players with pubic symphysitis.<BR>Results indicate that these three simple tests : MF, trunk extension in the prone position and external rotation of the hip joint in the standing position, can be used as valuable indices for detecting pubic symphysitis in the early stages.
