The aim of our study was to compare plicometry and bioelectrical impedance analysis as methods for body composition assessment (fat mass-FM%, fat-free mass-FFM) and to extrapolate population-specific equations in order to predict the plicometrically-derived FM and FFM on the basis of body resistance. A cross-sectional study was carried out at the Diabetes Out-Patient Clinic, Department of Internal Medicine, University of Palermo, Italy. We examined 102 subjects (45 men, 57 women, age range 30-45 years) divided into three groups: Group N (36 normal weight subjects, body mass index-BMI = weight/height2 = 24.5 +/- 0.8), Group O (35 obese subjects, BMI = 35.1 +/- 0.4), and Group GO (morbid obese subjects, BMI = 49.2 +/- 1.2) as well as a control group of 30 subjects (12 men, 18 women, age range 30-45 years, BMI = 20.9-63.1). We measured the following parameters: bioelectrical impedance analysis (body resistance: R), plicometry (triceps, biceps, subscapular, and suprailiac skinfolds), height (Ht), weight (W). The two methods were comparable in Groups N and O. In Group GO, however, especially in men and for FM%, measurements were significantly different. Plicometrically-determined FM% and FFM-Kg were significantly correlated to R.W/Ht2 (r = 0.821, p < 0.0001) and to Ht2/R (r = 0.867, p < 0.0001) respectively. The following prediction formulas for plicometric FM and FFM from body resistance and anthropometric variables were obtained: 1) FM% = 22.3 (R.W/Ht2)-2.2, and 2) FFM-Kg = 1.1 (Ht2/R)-3.1.(ABSTRACT TRUNCATED AT 250 WORDS)
我们研究的目的是比较褶厚度测量法和生物电阻抗分析这两种身体成分评估方法（脂肪量-FM%，去脂体重-FFM），并推断出特定人群的方程，以便根据身体电阻预测通过褶厚度测量法得出的FM和FFM。在意大利巴勒莫大学内科糖尿病门诊进行了一项横断面研究。我们检查了102名受试者（45名男性，57名女性，年龄范围30 - 45岁），分为三组：N组（36名体重正常受试者，体重指数-BMI = 体重/身高² = 24.5 ± 0.8），O组（35名肥胖受试者，BMI = 35.1 ± 0.4），以及GO组（病态肥胖受试者，BMI = 49.2 ± 1.2），还有一个由30名受试者组成的对照组（12名男性，18名女性，年龄范围30 - 45岁，BMI = 20.9 - 63.1）。我们测量了以下参数：生物电阻抗分析（身体电阻：R）、褶厚度测量法（肱三头肌、肱二头肌、肩胛下和髂上皮肤褶厚度）、身高（Ht）、体重（W）。在N组和O组中，这两种方法具有可比性。然而，在GO组中，尤其是男性和FM%方面，测量结果存在显著差异。通过褶厚度测量法确定的FM%和FFM - Kg分别与R·W/Ht²（r = 0.821，p < 0.0001）和Ht²/R（r = 0.867，p < 0.0001）显著相关。得出了以下根据身体电阻和人体测量变量预测褶厚度测量法得出的FM和FFM的公式：1）FM% = 22.3（R·W/Ht²）- 2.2，以及2）FFM - Kg = 1.1（Ht²/R）- 3.1。（摘要截断于250字）
