Abstract:

Objective To analyze the distribution and changing characteristics of fat in Yugur adults of Gansu. Methods Totally 1086 Yugur adults of Gansu province (366 males and 720 females) were selected by a multi-stage stratified cluster random sampling method. The body composition of fat was measured by the body composition analyzer. Results The total fat mass, subcutaneous fat content, trunk and limbs fat mass in female adults of Yugur in Gansu were higher than those in male (P<0.01). There was no significant difference in visceral fat content between male and female (P>0.05). In different ages, the total fat mass, subcutaneous fat content, trunk and limbs fat mass in female were higher than in male (P<0.01) except visceral fat content (P>0.05). With age, body fat content increased constantly in yugur adults. The rapid periods were 20-29 and early 40-49 age groups, and declined after upper 60-69 age. Comparison of the rise and decline of body fat content was more significant in the female. Conclusion Total fat mass, subcutaneous fat content, trunk and limbs fat mass in female adults of Yugur in Gansu are higher than those in males except visceral fat content. Fat content among body increases with age in Yugur adults, and declines after 60-69 age.
