Determination of body composition of"Aerwa","Khmus"and"Manmi"Blang ethnic groups by bioelectrical impedance analysis
To explore the body composition characteristics of the three Blang ethnic groups,"Aerwa","Khmus"and"Manmi",the body mass and 17 body composition indicators of 692 adults(305 males,387 females)from the three Blang ethnic groups in Yunnan Province were investigated by bioelectrical impedance analysis,and the indicators were analyzed statistical-ly.The results were as follows:① Both the percent body fat and total body muscle mass of Khmus were the highest among the three ethnic groups,labor intensity and eating habits were the reasons for the rich fat and more muscle of Khmus.② The total body muscle mass,estimated bone mass,total energy metabolism and trunk muscle mass of males in the three ethnic groups showed negatively correlated with age,while the visceral fat level of males showed positively correlated with age.The total body muscle mass,total energy metabolism and trunk muscle mass of females in the three ethnic groups showed negatively correlated with age.③ Judging obesity according to percent body fat,the obesity rate of females was higher than that of males in the three ethnic groups.The visceral fat level of males was higher than that of females in the three ethnic groups.④ The three Blang eth-nic groups were closer in body composition and differ more from the Bulangshan Blang.
