The assessment of skinfold thickness is an objective measure of adiposity. The aims of this study were to establish Colombian smoothed centile charts and LMS L (Box-Cox transformation), M (median), and S (coefficient of variation) tables for triceps, subscapular, and triceps + subscapular skinfolds; appropriate cut-offs were selected using receiver operating characteristic (ROC) analysis based on a population-based sample of children and adolescents in Bogotá, Colombia. A cross-sectional study was conducted in 9618 children and adolescents (55.7% girls; age range of 9-17.9 years). Triceps and subscapular skinfold measurements were obtained using standardized methods. We calculated the triceps + subscapular skinfold (T + SS) sum. Smoothed percentile curves for triceps and subscapular skinfold thickness were derived using the LMS method. ROC curve analyses were used to evaluate the optimal cut-off point of skinfold thickness for overweight and obesity, based on the International Obesity Task Force definitions. Subscapular and triceps skinfolds and T + SS were significantly higher in girls than in boys (p < 0.001). The ROC analysis showed that subscapular and triceps skinfolds and T + SS have a high discriminatory power in the identification of overweight and obesity in the sample population in this study. Our results provide sex- and age-specific normative reference standards for skinfold thickness values from a population from Bogotá, Colombia.
皮褶厚度评估是肥胖程度的一种客观测量方法。本研究的目的是建立哥伦比亚肱三头肌、肩胛下及肱三头肌 + 肩胛下皮褶厚度的平滑百分位数图表以及LMS（L为Box-Cox变换、M为中位数、S为变异系数）表；基于哥伦比亚波哥大的儿童和青少年人群样本，采用受试者工作特征（ROC）分析选择合适的临界值。对9618名儿童和青少年（女孩占55.7%；年龄范围为9至17.9岁）进行了一项横断面研究。使用标准化方法测量肱三头肌和肩胛下皮褶厚度。我们计算了肱三头肌 + 肩胛下皮褶（T + SS）总和。采用LMS方法得出肱三头肌和肩胛下皮褶厚度的平滑百分位数曲线。根据国际肥胖特别工作组的定义，使用ROC曲线分析来评估皮褶厚度对于超重和肥胖的最佳临界值。女孩的肩胛下和肱三头肌皮褶以及T + SS显著高于男孩（p < 0.001）。ROC分析表明，在本研究的样本人群中，肩胛下和肱三头肌皮褶以及T + SS在识别超重和肥胖方面具有较高的辨别力。我们的结果为来自哥伦比亚波哥大人群的皮褶厚度值提供了性别和年龄特异性的标准参考标准。
