The Determination of Subcutaneous Body Fat Percentage by Measuring Skinfold Thickness in Teenagers in Turkey

Our aim in this study was to determine the body fat percentage of teenagers in Diyarbakir, a city in southeast Turkey. The study included 1118 children between the ages of 10 to 15. Basic anthropometric measurements including body-mass index (BMI) and skinfold thickness were taken. The skinfold thickness were measured with a Lange skinfold caliper. Fat mass percentage (FM %) was predicted by using skinfold thickness equations. Differences between boys and girls across age groups for weight, height, and BMI were found to be statistically significant (P < 0.0001). With respect to skinfold thickness in the 10-y-old group, the thickness at triceps and subscapular sites in girls was higher than those of boys. In the 12-y-old group, the thickness was found to be higher in girls than boys at the triceps, biceps, and subscapular sites. We found that an increase in skinfold thickness in the 13, 14, and 15-y-old groups was significantly higher among girls than boys and tended to increase with age. However, such a tendency was not shown in boys. This tendency was found only at the triceps site in 10, 12, and 13-y-old boys. In addition, the skinfold thickness at the biceps site was found to be greater in the 14-y-old boys. The body fat mass percent in girls, especially those older than age 13, was also increased.
