目的利用生物电阻抗技术探讨不同性别、不同体重状态人群的人体成分构成特点.方法 2005年5月至2011年4月到解放军总医院体检人群,共61 379人,其中男性39 852人,女性21 527人.应用生物电阻抗法测量受试者人体成分,主要检测指标有体质指数(BMI)、体脂肪量等.结果 (1)应用BMI判定肥胖时,70岁以下同年龄男性的超重率和肥胖率均明显高于女性(均P＜0.01);(2)60岁以下成年男性和70岁以下成年女性的超重率和肥胖率随增龄而增高；(3)同年龄女性的体脂肪率均显著高于男性,且差异随年龄增长而增加,在70岁以上差异最显著(36％±6％比24％±7％,P＜0.01)；(4)随着BMI升高,体脂肪率有增加趋势,总体男性的肌肉量、体水分量、无机盐占体重比例均高于女性,(肌肉量/体重:0.708±0 066比0.664±0.063,体水分量/体重:0.520±0.044比0.474±0.042,无机盐/体重:0.040±0 004比0.036±0.004,均P＜0.01),而总体女性的蛋白质占体重比例稍高于男性(P＜0.01).结论男性总体的BMI水平高于女性,而相同BMI水平的女性体脂肪率高于男性；评价人群超重率和肥胖率时,特别是女性人群,综合体脂肪率评价肥胖状况更为准确.

Objective To explore the characteristics of body composition among male and female adults with different body weights.Methods A total of 61 379 healthy adults (39 855 males and 21 527 females) were referred to our health examination center between May 2005 and February 2011,Body mass index (BMI) and body composition contents of fat,water,muscle,protein and mineral salt were measured by anthropometric measurements and bioelectrical impedance analysis (BIA).The data were analyzed among groups divided by gender,age and BMI.Results (Ⅰ) The prevalence of overweight and obesity defined by BMI was significantly higher in the male group than the female of the same age group under 70 years old (all P＜0.01).(2) Within a certain age range (＜60 in males,＜70 in females),the prevalence of both overweight and obesity defined by BMI increased with age (all P ＜ 0.01).(3)The fat mass percentage was significantly higher in females than in males of the same age group.The difference became more and more significant with advancing age.And the most significant difference was found in the upper 70 years old group (fat mass rate of males vs females,24％ ±7％ vs 36％ ±6％,P＜0.01).(4) Body fat mass percentage progressively elevated with increases of BMI while there was a decreasing trend of other body composition contents.The total male subjects had higher percentage of muscle,water and mineral salt than females (percentage of muscle,water and mineral salt of males vs females,0.708 ± 0.066 vs 0.664 ±0.063,0.520 ± 0.044 vs 0.474 ± 0.042,0.040 ± 0.004 vs 0.036 ± 0.004,all P ＜ 0.01) while the percentage of protein was higher in the total female group (P ＜ 0.01).Conclusions Females has more fat mass than males under the same BMI.So it is more reasonable to introduce adiposity for the evaluation of obesity,especially in females.
