  • OBJECTIVES: The aims of this study were to establish a Colombian smoothed centile chartsand LMS tables for tríceps, subscapular and sum tríceps+subscapular skinfolds; appropriatecut-offs were selected using receiver operating characteristic analysis based in a populationbasedsample of schoolchildren in Bogota, Colombia and to compare them with internationalstudies.METHODS: A total of 9 618 children and adolescents attending public schools in Bogota,Colombia (55.7% girls; age range of 9–17.9 years). Height, weight, body mass index (BMI),waist circumference, triceps and subscapular skinfold measurements were obtained usingstandardized methods. We have calculated tríceps+subscapular skinfold (T+SS) sum.Smoothed percentile curves for triceps and subscapular skinfold thickness were derived by theLMS method. Receiver operating characteristics curve (ROC) analyses were used to evaluatethe optimal cut-off point of tríceps, subscapular and sum tríceps+subscapular skinfolds foroverweight and obesity based on the International Obesity Task Force (IOTF) definitions. Datawere compared with international studies.RESULTS: Subscapular, triceps skinfolds and T+SS were significantly higher in girls than inboys (P <0.001). The median values for triceps, subscapular as well as T+SS skinfold thicknessincreased in a sex-specific pattern with age. The ROC analysis showed that subscapular, tricepsskinfolds and T+SS have a high discrimination power in the identification of overweight andobesity in the sample population in this study. Based on the raw non-adjusted data, we foundthat Colombian boys and girls had high triceps and subscapular skinfolds values than theircounterparts from Spain, UK, German and US.CONCLUSIONS: Our results provide sex- and age-specific normative reference standards forthe triceps and subscapular skinfold thickness values in a large, population-based sample of3schoolchildren and adolescents from an Latin-American population. By providing LMS tablesfor Latin-American people based on Colombian reference data, we hope to provide quantitativetools for the study of obesity and its complications.
