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 investigate the distribution and changes of fat in Yugur adults in Gansu and to provide references for the health guidance and related diseases of this ethnic group. Methods A stratified cluster random sampling method was used to measure the fat-related body composition of 1086 Yugu people in Gansu, including 336 males and 720 females, using bioelectrical antibody component analyzer. Results The total fat mass, subcutaneous fat mass, trunk and extremity fat mass of Yugu adult women in Gansu Province were higher than those in male (P <0.01). There was no significant difference in visceral fat content (P> 0.05). The total fat mass, body fat mass, extremity fat mass, and subcutaneous fat mass of females were significantly higher than those of males (P <0.01), but there was no significant difference in visceral fat content among different age groups (P> 0.05). The body fat content of Yugur adults increased with the increase of age. The growth rate was significantly increased in the age group from 20 to 29 years old to the age of 40 to 49 years old, and then slowly decreased after reaching the peak in the age group of 60 to 69 years , The fat content of both lower extremities peaked in the 40-49 age group, and the rising and declining trend of fat content of females were more significant than that of males. Conclusion There is no gender difference in the visceral fat content of Yugu adult in Gansu Province, while the rest of female fat content is higher than that of male in Yugu people. The total fat mass and the fat content of various parts of Yugu people in Gansu Province are generally increasing with age, ~ 69 age group began to decline late.
