目的 探讨甘肃裕固族成人脂肪分布及变化特点，为该民族人群健康指导及相关疾病的研究提供参考。 方法 采用分层整群随机抽样方法，应用生物电阻抗体成分分析仪测量1086 例甘肃裕固族成人，其中男性336例，女性720例的脂肪相关体成分指标。 结果 甘肃省裕固族成年女性的总脂肪量、皮下脂肪含量、躯干及四肢脂肪量均高于男性 (P<0.01)；内脏脂肪含量无显著性差异 (P>0.05)。不同年龄段身体各脂肪含量男、女性比较，女性的总脂肪量、躯干脂肪量、四肢脂肪量、皮下脂肪量均高于男性(P<0.01)，内脏脂肪含量比较差异无显著性(P>0.05)；裕固族成人体脂含量随年龄的增长均呈上升趋势，20～29 岁年龄段到 40～49 岁年龄段前期为快速增长期，在60～69岁年龄段达到峰值后呈缓慢下降，双下肢脂肪含量在40～49岁年龄段达峰值，女性脂肪含量上升趋势和下降趋势较男性均更为显著。 结论 甘肃省裕固族成人内脏脂肪含量无性别差异，其余各部位脂肪量女性均高于男性；甘肃裕固族成年人总脂肪量和身体各部位脂肪含量随着年龄增长总体呈上升趋势，之后在 60～69岁年龄段后期开始下降。

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.
