Abstract:

Objective To analyze the changing characteristics of non-fat tissue body composition in Dongxiang adults of Gansu by a bioelectrical impedance analysis method. Methods A total of 491 Dongxiang adults aged over 20 years in Dongxiang autonomous county of Gansu Province were selected by the cross-sectional stratified random sampling method. The non-fat tissue body composition indexes were measured by body composition analyzer. Results The mass to constituent ratio of lean body mass, bone mass, muscle mass, protein and total body water were higher in male adults of Dongxiang in Gansu than in female (P<0.01), and bone mass, muscle mass, protein and total body water were same in different age groups. Bone mass and muscle mass showed the same trend in the same gender. One of the peaks of them was in 40 age group in male adults, and they decreased at first and then increased up to peak in 40 age group in female. The protein in male decreased after the peak of 30 age group, and decreased in female. Trunk muscle mass in male and female decreased after the peaks of 50 age group and 40 age group respectively. Double upper limbs muscle mass and total body water in both decreased after the peak of 40 age group. Double lower limbs muscle mass in male showed a downward trend except that there was a slight rebound in 40 age group, and always decreased in female. Intracellular water decreased at first and then increased up to peak in 40 age group in both. Extracellular water in male and female decreased slightly after the peaks of 50 age group and 40 age group respectively. Conclusion Non-fat tissue body composition indexes in Dongxiang adults of Gansu in male are higher than in female in different age groups and all of them changed with age. There are gender differences in the trend of the remaining body composition except double upper limbs muscle mass, total body water and Intracellular water. In general, the characteristics of non-fat tissue body composition in female adults of Dongxiang are less mass than in male, decrease continuously with no peak of partial body composition or earlier peak, decrease earlier, and decrease more slowly than in male.
