Information on patterns of skinfold thickness may help to understand changes in body<br />composition during growth. The objectives of this study were to observe patterns of BMI, percentage<br />body fat (%BF), and skinfold thicknesses of Indonesian children and adolescents aged 7–18 years.</p><p><strong>Methods</strong>: Weight, height, and four skinfold thicknesses were measured in 2104 school children (924<br />boys, 1,180 girls) aged 7–18 years from Yogyakarta between 2015 and 2018. BMI and ratios between<br />central and peripheral skinfold thicknesses were determined. %BF was predicted using the equation<br />of Slaughter et al. Data were analyzed using analysis variance (ANOVA), independent sample<br />t‑test, and partial correlation (SPSS version 20.0).</p><p><strong>Results</strong>: At 7–18 years, boys and girls showed<br />a comparable gain in BMI. The comparable gain in %BF between boys and girls only occurred<br />till age 10 and total skinfolds till age 11 years. While, %BF and skinfold thicknesses were higher<br />in girls at 12–17 years, central to peripheral skinfold ratio were higher in boys. Partial correlation<br />analyses showed that all skinfold thickness parameters and %BF were significantly correlated with<br />BMI (P &lt; 0.001; r = 0.19–0.87).</p><p><strong>Conclusions</strong>: The gain in BMI and skinfold thickness between the<br />ages of 7 and 18 years occurred in age‑ and sex‑specific patterns. Instead of comparable BMI, girls<br />showed higher means of total skinfold thickness from age 12 years, while boys had higher central to<br />peripheral adiposity ratio.</p><p> </p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2336http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2336/717718178
