A sample of 104 adults underwent testing of body composition by multiple frequency bioelectric impedance analysis (MBIA) under controlled conditions, by anthropometric methods (skinfold thicknesses and BMI) and by the urinary creatinine method. The statistical comparison of body composition parameters (Fat, FFM, TBW), estimated by different methods for the same subjects, pointed out significant differences in mean values. The precision of skinfold and MBIA measurements was evaluated by a second control measurement. Concerning the MBIA, the reliability increased with increasing frequencies. Nevertheless, measurement reliability is higher for skinfolds than for MBIA. Under the condition that there is a real anthropometric technical ability, we affirm that the body composition parameters may at present be better estimated by the skinfold method.
104名成年人的样本在可控条件下，通过多频生物电阻抗分析（MBIA）、人体测量方法（皮褶厚度和体重指数）以及尿肌酐法进行了身体成分测试。对同一受试者采用不同方法估算的身体成分参数（脂肪、去脂体重、总体水）进行统计比较，结果显示平均值存在显著差异。通过第二次对照测量评估了皮褶和MBIA测量的精度。关于MBIA，其可靠性随频率增加而提高。然而，皮褶测量的可靠性高于MBIA。在具备实际人体测量技术能力的条件下，我们断言目前通过皮褶法可能能更好地估算身体成分参数。
