RESUMO
Objective To understand the body characteristics of adults from the Tibeto-Burman language group. Methods Totally 14 837 adults (6578 males and 8259 females) from 17 minorities were selected for investigation during 2015 to 2019 and these surveys were carried out in regions including Sichuan, Yunnan, Guizhou, Hubei, Hunan and Tibet Autonomous Region. Eight physical parameters (stature, sitting height, etc.) along with 4 corresponding indexes (stature-sitting index and the like) were carefully analyzed. The body characteristics of the Tibeto-Burman language group were then compared to those of certain minorities as well as Han in both northern and southern part of China based on our collected data. Results Among 17 minorities of the Tibeto-Burman language group, people from Pumi and Tibet were relatively tall and have longer trunk and limbs. The presence of wider trunk and thicker limbs appeared to be common in Tibetan individuals. Subjects from Lahu, Jino and Derung were in possession of shorter stature and limbs while the trunk of Naxi, Lisu and Achang people seemed wider. Compared with other ethnic groups in China, individuals from the Tibeto-Burman language group tended to own shorter stature accompanied by medium trunk width, probably sharing similar physical characteristics with those minorities in southern China, especially She and Li. Conclusion Among ethnic groups dotting in southern China, individuals from the Tibeto-Burman language group generally have medium stature, medium trunk height, and wide trunk whereas those from 3 Mon-Khmer groups, Va, Khmus and Blang, are shorter and smaller in width and height of the trunk.
RESUMO
Objective To analyze the nutritional level, obesity status and the prevalence of frypertension in Blang, Deang and Va ethnic groups in Yunnan, to explore the relationship among nutritional physical index, obesity indicators and blood pressure, and use the cutoff value of related indicators to warn frypertension. Methods This paper was based on a statistical analysis of the 7 nutritional pfrysical indexes, 5 types of obesity status and frypertension status of 766 Blang, 570 Deang and 565 Va. Results We found that the nutritional pfrysique index of man)' items (4 items for men and 4 items for women) of Blang was significantly higher than that of Deang and Va (P Blang > Deang and the difference was statistically significant (P<0. 05). Conclusion Pelidisi' s index, WHR, and PBF all have good early warning effects on frypertension in all three ethnic groups.
RESUMO
Objective To investigate the characteristics of bod)' circumference of Tibetan-Burman adults. Methods Using a human bod)' altimeter and a measuring tape, the height and 9 circumference indicators of 14 722 adults from 17 Tibetan-Bunnan ethnic groups in Sichuan, Yunnan, Guizhou, Hubei, Hu ' nan and Tibet Autonomous Region were measured from 2015 to 2019, 5 circumference indexes were calculated, and the data were statistically analyzed. Results The higher the longitude, the larger the head circumference, thigh circumference, biceps circumference and foreann circumference of Tibetan-Bunnan adults and the female maximum biceps circumference, and the smaller the trunk circumferences and male calf circumference; The higher the latitude, the larger the circumferences (except for female thigh circumference); The higher the altitude, the larger the circumferences; The higher the temperature, the smaller the circumferences. Conclusion Among the 17 ethnic groups of Tibeto-Burman, the Tibetan has a larger circumference, while the Gongshan Nu, Lahu, and Drung have relatively small and close circumferences. With age, the chest and waist circumferences of Tibetan-Bunnan adults increase, and the circumference of the limbs decreases.
RESUMO
Objective To study the feasibility of neck circumference on the prediction of obesity by analyzing the relationship between the neck circumference and the obesity, and to provide the reference for the early prevention of obesity and related diseases. Methods A total of 1859 adults (911 males and 948 females) were selected from the four ethnic groups of Lingao, Li, Qiang and Baima as the subject of the study. The correlation between the neck circumference and body mass index (BMI), percent body fat, visceral fat index, waist circumference, waist hip ratio and body adiposity index were analyzed by correlation analysis, u test and receiver operating characteristic (ROC) curve analysis and Kappa consistency test. Results Neck circumference has significant positive correlations with several other obesity indicators. It has the least correlation with body adiposity index and waist hip ratio, and has greater correlation with waist circumference, visceral fat index, and percent body fat, and has the largest correlation with BMI. The average values of the neck circumference of the obesity group judged by different obesity indicators are larger than the normal group, and the difference is statistically significant. ROC curve analysis and Kappa consistency test show that the area under curve (AUC) of neck circumference and various obesity indicators are greater than 0.7, and the consistency of neck circumference, BMI and waist circumference is the best when judging obesity. Conclusion If the value of male neck circumference is greater than the critical cut point value 364.5, the female neck circumference value is greater than 319.5, which can be predicted that the BMI value is overweight or obese. When the neck circumference of male is greater than 370.5 and the neck circumference of female is greater than 319.5, it can be predicted that the waist circumference exceeds the standard, and the risk of central obesity increases.
