Three obesity indicators predicting central obesity in Naxi and Pumi ethnic groups in Yunnan Province and inter-ethnic comparison / 解剖学报

ABSTRACT

Objective To compare the predicted value of three different obesity indicators of on center obesity of Naxi and Pumi adult in Lijiang City, Yunnan Province; To calculate the best cut-off point of waist-to-height ratio(WHtR), body mass index(BMI) and abdominal volume index(AVT); And to compare the differences of BMI and WHtR between the Naxi, Pumi and North-South ethnic groups, so as to provide scientific reference for central obesity and related diseases. Methods By random sampling, 658 cases of Naxi adults (278 cases for men and 380 cases for women) and 496 cases of Pumi adults (2 1 6 cases for men and 280 cases for women) were selected as the subjects of the study, taking the internationally recognized visceral fat level (V F L) as the diagnostic criterion of central obesity, the relationship between WHtR, BMI, AVI and VFL was discussed by regression analysis, and the value of three obesity indicators was predicted by comparing the receiver operating characteristic (ROC) curve of the subjects. Using Excel 2019 to draw diagrams and SPSS 23. 0 to process data. Results The six indicators of age, weight, height, waist circumference, hip circumference and AVI of Naxi and Pumi men were statistically significant among different ethnic groups (P < 0 . 05); Naxi and Pumi women' s age, height, waist circumference, WHtR, BMI and abdominal volume index, the six indicators were statistically significant among different ethnic groups (P < 0 . 0 1) . Correlation analysis showed that the three indicators of WHtR, BMI and AVI were positively related to VFL (P< 0 . 0 1) . The ROC showed that the WHtR had the highest value for predicting central obesity in Naxi and Pumi men (P<0. 01), BMI had the highest value of predicting central obesity in Naxi and Pumi women (P<0. 0 1) . Cluster analysis showed that Naxi and Pumi males were similar to southern ethnic groups such as Lisu and Sui, Naxi females were similar to Zang and Jingpo, and Pumi females were similar to southern ethnic groups such as Lisu and Sui. Conclusion WHtR, BMI, AVI to determine central obesity are statistically significant, can be combined with BMI and AVI to determine Naxi, Pumi central obesity.
