广西巴马世居成人的皮褶厚度及其年龄特征

The variations of skinfold thickness with aging of indigenous people adults in GuangXi Bama

目的:探索世界第5长寿之乡广西巴马成人体脂发育水平及年龄变化特征。方法:测量992例(男463人,女529人)巴马20-110岁组世居人群6项皮脂厚度值。结果:(1)皮下脂肪男性以躯干背部最厚,面部、腹部居中,四肢较薄。女性腹部、下肢、面部、背部的皮下脂肪厚度值相当,均较丰厚。男女均以上臂前部皮下脂肪最薄。(2)男性6项皮褶厚度最大值均出现在20岁组,其随年龄增加下降幅度不明显;女性6项皮褶厚度值(除腓位外)均在40岁组升达高峰,以后则明显下降。结论:广西巴马世居人群皮脂发育水平在40岁左右处于巅峰值,之后呈现缓慢下降,女性下降较快,皮脂发育水平适中,与北方的俄罗斯族、乌孜别克族相近,优于布依族及广西东部壮族。

Objective： To study the body fat development and the thickness changes with aging from the fifth longevity township in Indigenous people adults in Guangxi bama. Methods： Six skinfold thickness parameters and the traits of their variations with age were investigated in 992 Indigenous people adults including 463 males and 529 females. Results：The skinfold thickness of the back torso skinfolds is the thickest in the male. The face and belly’s is located in the medium. In addition, limbs’s is very thin. Women＆#39;s subcutaneous fat thickness value of the abdomen and lower limbs is more thick and the same as the face and back’s. The Upper arm anterior subcutaneous fat is the most thin in the men and women;Six male skinfold maximum have appeared in the group of 20 years old, its decline is not obvious with increasing age;Six female skinfold values （except Sura position） rise to the peak at the age of 40, and then start to be markedly reduced. Conclusion：The sebum growth level is at the peak value in indigenous people adults on the age of 40 in Guangxi bama, then decline slowly. However, women’s fall faster. The sebum growth level of them is moderate and similar to northern ethnic Russians and Uzbeks. And furthermore, they are superior to the Bouyei nationality living in Guizhou and zhuang nationality in the east of guangxi, China.
