[Abstract] Objective To explore the somatotype characteristics of Zhuang-Dong ethnic groups in China. Methods The Heath-Carter somatotyping method was used to study the somatotypes of 9965 (male 4312, female 5653) cases from 15 Zhuang-Dong language groups. Results The average somatotype of males in the Zhuang-Dong ethnic group were 4. 1-5. 2-1. 9, which belonged to the mesodermal somatotype of partial endoderm, and the mean somatotype of women were 5. 5-4. 9-1. 3, which belongs to the endoderm somatotype of partial mesoderm. Except for endomorphy factor and SAM, height, weight, mesomorphy, ectomorphy and HWR of all age groups of males were greater than those of females. There were statistically significant differences in somatotype among the three age groups among the sexes of the Zhuang-Dong language group. The weight, height, and ectomorphy of men and women were negatively correlated with age, and endomorphy were positively correlated with age. Among them, the male mesomorphy was not correlated with age, and the female mesomorphy was positively correlated with age. The differences between male and female three-factor value age groups were statistically significant. Conclusion The somatotype of male and female of Zhuang-Dong ethnic group has obvious changes with the increasing of age, and the southern ethnic group has the characteristics of low linearity, well-developed bones and muscles, and plump body fat.

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.

Objective To investigate the prevalence rate and biochemical characteristics of frypertension in Zhuang-Dong ethnic groups in China. Methods Blood pressure and biochemical indexes were measured in 7411 cases (3248 males and 4163 females) from 5 ethnic groups of Zhuang-Dong nationality. Results The difference of crude prevalence rate of hypertension among Zhuang-Dong language groups was statistically significant. The crude prevalence of Irypertension in males of the same age group was higher than that in females. Systolic blood pressure and diastolic blood pressure in males and females increased with age, and the crude prevalence of Irypertension also increased with age. The mean values of triglyceride, cholesterol and low density lipoprotein in males of Zhuang-Dong language group were all lower than those of females. The mean levels of blood uric acid, blood urea and blood lipid in hypertensive patients were significantly higher than those with nonnal blood pressure; the mean levels of bilirubin and serum protein in Irypertensive patients were close to those with nonnal blood pressure; the mean levels of blood lipid in Irypertensive patients were more than the nonnal range. Conclusion The prevalence of Irypertension in Zhuang-Dong ethnic group is high. The patients with Irypertension should pa)' attention to the increase of blood uric acid, blood urea and blood lipid.
Résumé
Objective To discuss the law of the change of body composition of Zhuang-Dong ethnic groups with the change of natural geographical factors(longitude, latitude, annual average temperature and annual average sunshine). Methods The bioelectrical impedance analysis (BIA) was used to measure the body composition data of 5098 cases of 13 ethnic groups of Zhuang-Dong group in China. At the same time, collect the relevant data of longitude, latitude, annual average temperature and annual average sunshine of 13 ethnic groups, and use per capita disposable income as a control variable to perform partial correlation analysis about body composition with longitude, latitude, annual average temperature, and annual average illumination. Results Zhuang-Dong group fat rate decreased and little change in muscle mass, presumption of bone mass, and water content with the increase of longitude. With the increase of latitude, the fat rate of males in the Zhuang-Dong ethnic group decreasesd, muscle mass increased (mainly muscles in the extremities), female fat rate increased, and muscle mass decreased (mainly in upper limbs and trunk muscles). In general, with the increase of the average annual temperature, the fat rate of males in Zhuang and Dong ethnic groups increased, lower limb muscles decreased, female fat rate decreased, and muscle mass increased. With the increase of the average annual sunshine, the body fat rate of men increased and the muscle mass decreased; the body fat rate of women decreased and the muscle mass increased. Conclusion Natural geographical factors (longitude, latitude, annual average temperature, and average annual sunshine) have significant effects on the body composition of the Zhuang-Dong ethnic group.
