Abstract:

Objective To analyze the changing characteristics with age of body fat mass and distribution of Dongxiang nationality adults in Gansu by bioelectrical impedance analysis method. Methods A total of 491 Dongxiang adults in Dongxiang autonomous county of Gansu Province were selected by cross-sectional stratified random sampling method. The body composition of fat was measured by body composition analyzer. Results In the general population and different age groups, the total fat mass, subcutaneous fat mass, trunk and limbs fat mass in the female adults of Dongxiang in Gansu were higher than in the male (P<0.01), and there was no significant difference in the visceral fat mass between the male and female (P> 0.05). With age, visceral fat mass increased constantly in both male and female. Subcutaneous and trunk fat mass in male and female showed a rising trend of increasing quickly from 20 age group to 40 age group, decreasing slightly in 50 age group and subsequently rising slowly. Left upper limbs fat mass in the female increased constantly, increased quickly from 20 age group to 40 age group and subsequently rising slowly. Left upper limbs fat mass in the male showed a rising trend of increasing quickly from 20 age group to 40 age group, decreasing slightly in 50 age group and subsequently rising slowly. Double lower limbs and right upper limbs fat mass decreased after the peak of 40 age group. Conclusion Fat mass in Dongxiang nationality female adults is higher than in male except visceral fat mass. Fat mass of Dongxiang adults in Gansu changed with age, and it is somewhat different in different genders and parts. Visceral fat mass in both genders and left upper limbs fat mass in the female increase constantly. The 50 age group is the time point when the trend of fat in each part changes.
