In order to explore the characteristics of body composition of Maonan adults,the bioelectric impedance analysis was used to measure the body composition of 476 Maonan adults(204 males,272 females)in Guangxi Zhuang Autonomous Region.The results were as follows:① The percents of trunk fat was the highest in males,while the percent of lower limb fat was the highest in females.The trunk muscle mass in both males and females were the highest.The muscle mass of males was greater than that of females,while the percent of fat was less than that of females.② The correlation analysis results showed that the percent of body water and visceral fat level of males had significant positive correlation with age.Ten indicators including body mass,stature,total body muscle mass,estimated bone mass,right upper limb muscle mass,left upper limb muscle mass,right lower limb muscles,percent of left lower limb fat,left lower limb muscle mass and trunk muscle mass of males had significant negative correlation with age.The visceral fat level of females had significant positive correlation with age,while stature and estimated bone mass had significant negative correlation with age.③ The results of one-way analysis of variance showed that,except for seven indicators including percent body fat,body mass index,percent of body water,percent of right upper limb fat,percent of left upper limb fat,percent of right lower limb fat,percent of trunk fat,the age group differences of the other 11 in-dicators of males were statistically significant.Except for four indicators including percent of body water,percent of right upper limb fat,percent of right lower limb fat,percent of left lower limb fat,the age group differences of the other 14 indicators of females were statistically significant.④ According to the obesity criterion determined by percent body fat,both males and fe-males were normal.According to the body mass index criteria for overweight and obesity,both males and females were over-weight.⑤ The value of body composition of Maonan was close to those of other southern ethnic groups,but different from those of northern ethnic groups.
