临夏州回族成人体成分分析

Body composition analysis of Hui adults in Linxia

目的:搜集临夏州回族成人体成分数据、分析其体成分特点及随年龄变化的规律。方法:采用整群随机抽样的方法,对临夏州回族成人,男224人,女119人,利用生物电阻抗分析法进行体成分测量,用SPSS 16.0软件对所获数据进行统计学处理。结果:体质指数(BMI)随年龄增长均有升高的趋势,且都在50～达到高峰;体脂肪量和体脂肪率均随年龄增长而增长,男、女性的体脂肪率在各个年龄段均有差异;躯干及四肢脂肪量的变化规律与体脂肪率基本一致;女性BMI的肥胖检出率比体脂肪率的检出率低;体液、去脂体质量、肌肉量、蛋白质量及推定骨量等不同性别间均有差异,各指标随年龄变化不明显。结论:临夏州回族成人的体脂肪量及全身各部位脂肪量随年龄增长总体呈上升趋势;体成分存在性别差异,呈现出体脂肪率女性高于男性,而其他非脂肪成分的含量则男性高于女性的特点。

Objective:To explore the body composition distribution characteristics of Hui adults in Linxia by collecting the body composition data,and to analyze the change of body fat mass with age.Methods:343 healthy adult subjects(224 males,119 females)were randomly selected.Bioelectric impedance technique was used to test the body composition indices.All the collected data were analyzed with SPSS 16.0.Results:With the increase of age,body mass index(BMI)increased constantly in both males and females,and reached its maximum at the age of 50.The total fat mass and percent body fat(PBF)increased gradually with age.There were differences between male and female adults in percentage of body fat at all ages.PBF in the female adults was higher than that in the male adults at the age of 50.The change patterns of fat mass in the trunk and limb fat mass were the same as the PBF.The prevalence of obesity according to PBF was higher than BMI.There was significant difference between males and females in total body water,FFM,muscle mass,protein and estimated bone mass.Conclusion:With age,the total fat mass and fat mass of trunk and limbs increase constantly.In general,PBF of female adults are higher than male adults,while non-fat tissue body composition indexes in females are lower than males.
