Population-based centile curves for triceps, subscapular, and abdominal skinfold thicknesses in Polish children and adolescents--the OLAF study.

Jaworski M, Kułaga Z, Płudowski P, Grajda A, Gurzkowska B, Napieralska E, Swiąder A, Pan H, Litwin M, Olaf Study Gro - Eur. J. Pediatr. (2012)

Bottom Line: The study shows for the first time smoothed population-based values of body fat distribution indices for Polish children and adolescents 7-18 years of age.Reported skinfold centiles are higher compared to previously established for Warsaw children and very close to the actual US data.The early detection of abnormal fat stores, using our population-based values and respective Z scores, may be now implemented for practice.

ABSTRACT

Unlabelled: Skinfold thicknesses are used as valid anthropometric indicators of regional body fatness. Actual population-based values for skinfold thicknesses for Polish children are not available. The purpose of this study was to provide population-based values for triceps, subscapular, and abdominal skinfold thicknesses in healthy children and adolescents. A total number of 17,416 boys and girls aged 6.5-18.5 years, randomly selected from whole Polish population of children and adolescents, were enrolled in the study. Skinfold thicknesses (triceps, subscapular, and abdominal) were measured using Harpenden skinfold caliper. All measurements were taken after the training of participating investigators. The LMS method was used to fit percentile curves across age for each skinfold. Q tests for fit were used to assess the global goodness of fit of our final models. The study shows for the first time smoothed population-based values of body fat distribution indices for Polish children and adolescents 7-18 years of age. Reported skinfold centiles are higher compared to previously established for Warsaw children and very close to the actual US data.

Conclusion: Our study provided for the first time population-based values for skinfold thicknesses evaluation in a way allowing to calculate reliable Z scores. The early detection of abnormal fat stores, using our population-based values and respective Z scores, may be now implemented for practice.

Mentions: The smoothed percentiles for triceps, subscapular, and abdominal skinfold thicknesses are presented in Fig. 1 for boys and girls, separately. In girls, median for triceps skinfold thickness increased from 10.4 mm (6.5 years) to 15.6 mm (18.5 years) with plateau between 10 and 12 years and maximum (15.6 mm) at age 17.5 years. Ninety-seventh percentile increased from 20.5 mm at age 6.5 years to 27.9 at age 18.5 years with maximum (28.7 mm) at age 16.5 years. Plateau occurred between 10.5 and 12.0 years. Median for subscapular skinfold thickness increased from 10.0 to 11.8 mm for 6.5 and 18.5 years, respectively, and 97th percentile increased from 19.0 to 27.9 mm for the same ages. Median abdominal skinfold thickness increased from 6.6 mm (6.5 years) to 16.0 mm (18.5 years), and 97th percentile increased from 22.4 to 33.0 mm for the corresponding ages, respectively.Fig. 1
